Determination of Sodium Thiopental Using Gold Nanoparticles

Determination of Sodium Thiopental Using Gold Nanoparticles Development of a new colorimetric method for the determination of sodium thiopental using gold nanoparticles Sodium thiopental (sodium pentothal) is in a group of drugs called barbiturates.this barbiturate commonly used anesthetic induction agents in man and animals because recovery is rapid and it has the advantage of having very little or no side effects[1].It is used for intensive-care patients with head injuries to control convulsions and reduce raised intracranial pressure[2]. As a resultmonitoring of theserum concentrations is important in this patient population. Several analytical procedures have been reported for the quantitative determination of thiopental. Among these high-performance liquid chromatography (HPLC) are more popular. HPLC assays are not completely reliable, and do not have the short process-time required in most of the above-mentioned indications[3, 4]. other methods are available for determining thiopental including stripping voltammetry[5],membrane sensors[6],capacitive chemical sensor [7],gas chromatography (GC)[8],spectrophotometric and spectrophotofluorometric[9, 10]. Donald et al[11]reported that, after the usual 4.8 mg/kg induction doses, thiopental concentration in serum as a function of time varies between 10 mg/L to 25 mg/L during 50h.As stated before most of these currently used methods for sodium thiopental detection usually need expensive and complicated instruments and are time-consuming, making on-site and real-time thiopental detection difficult. Therefore, it is important to develop a simple reliable and hig hly sensitive method for on-site and real-time detection of sodium thiopental. Recently, gold nanoparticles (NPs) explored for metallic NP-based colorimetric detection have attracted considerable attention due to biocompatibility, stability, and high extinction coefficients[12]. gold nanoparticles present size-dependent optical properties owing to the surface plasma resonance(SPR)[12]. The color of the colloidal Au NPs can be readily and precisely changed via aggregation of Au NPs.Au NPs were widely applied in colorimetric detection of several analytes such as protein, DNA, metal ions and small molecules[ ]. In this study, we used gold nanoparticles as a colorimetric probe for sensitive and selective detection of sodium thiopental. The gold nanoparticles were prepared using the classical citrate method [12].thiopental on the surface of AuNPs displaced the stabilizing citrate ions because thiol group of sodium thiopental tends to readily adsorb onto the surface of colloidal gold via chemisorptions-type interactions. The thiopental capped Au NPs were stable at basic and neutral conditions .Puntes et al [13] have studied the stability of cationic gold nanoparticle bioconjugates as a function of pH and the presence of citrate in solution. The pH of an aqueous solution of thiopental-Au NPs was varied by direct addition of citrate buffer. the thiopental-Au NPs can be aggregated by adding certain amounts of citrate buffer due to the electrostatic attraction between amino group contained in thiopental molecular and citrate ion on the surface of Au NPs, the amino group of the thiopental would be positively charged at the given pH value and they would therefore interact electrostatically with the negative charges of the citrate molecules. Thus forcing the aggregation of the conjugated Au NPs and subsequently resulting in the color change from wine red to purple or blue color.So that we detected it by UV–Vis spectrophotometer and paptode techniques and contrast both methods.First time at 2004 paptode was developed in Dr. Abbaspour group for speciation of iron(II) and iron(III) and the full range pH monitoring [14]. Then it was used for the determination of dopamine [15], hydrazine [16]. In paptode, conventional à ¯Ã‚ ¬Ã¢â‚¬Å¡atbed -scanner (as a nondestructive detector) was used to acquire the analytical parameters for quantitative determination of analyte that occurs via colorimetric reaction. The estimated re à ¯Ã‚ ¬Ã¢â‚¬Å¡ection density, as an analytical parameter, is obtained from an area of the sensing zone of spots using the average Red (R), Green (G) and Blue (B) channel. Degrees of the color of the spots are found to be proportional to the concentration of the testedanalyte. Experimental section: Reagents: HAuCl4.3H2O, trisodium citrate and citric acid were purchased from Sigma. Thiopental was obtained from Biochemie (Kundl, Austria) and zinc sulfate purchased from Fluka All solutions were prepared with ultrapure water Apparatus and software: The colorimetric study of NPs were performed by means of a Shimadzu 1601PC UV–Vis spectrophotometer (Kyoto, Japan)from 300 to 700 nm. Also a Canon scanner were used to record the color changes in paptode technique. The paptode Cells were built by creation of the holes (i.d 1.5 cm) in the sheet of plexiglas (thickness 0.9 cm). We used by photoshop Cs6 software to convert the recorded pictures of color of cells to RGB (Red, Green and Blue) and L*a*b data. The morphology and size of the nanoparticles were characterized by a transmission electron microscope (TEM model CM10; Philips). The X-Ray diffraction (XRD) patterns were obtained by using a D8 ADVANCE type (BRUKER-Germany) with Cu-KÃŽ ± radiation (ÃŽ »= 0.1542 nm). Powder XRD patterns were taken in 0.02 ° steps at 1 s per step. All the experiments were carried out at room temperature(25  ± 2 C) Synthesis of citrate-stabilized Au nanocrystals: Nanoparticles of noble metal were prepared by classical citrate method[12].the10ml of 0.014M of trisodium citrate dehydrate solution was added quickly to the 100ml of boiling solution of 0.5mM of HAuCl4.3H2O under magnetic stirring. The stirring was continued until a dark red color was observed (around 20 min) and the maximum absorbance of AuNPs solution was centered at 520 nm Sample preparation: Fresh human blood samples (2.0 mL) were obtained from volunteers of the local hospital. After letting sample stand for 60 min at room temperature we centrifuged at 4000 rpm for 10 min. The supernatant was used as the source of the serum. We used zinc sulfate method as a deproteinization technique[]: we vortex-mix for 10s of the 10ml of serum sample and 150mg zinc sulfate, then we centrifuged the mixture at 3000 rpm for 20 min. The supernatant, which excluded protein, was used for further analysis. Procedures for the detection of sodium thiopental: In a typical detection of sodium thiopental, different amounts of thiopental solution were added to the above XmlAu NPs solutions at room temperature. we proceeded to study the behavior of the conjugated system by modifying the pH . To investigate the effect of pH of the buffer solutions on thiopental detection, 0.5 mL of 0.1 M buffer solution (citric buffer solution in the pH range of 3.0–6.0 ) was added in mixture of thiopental and Au NPs solution. The obvious color change was observed with the naked eye and the absorbance spectra and scanning images of the solution were recorded 1 min after the addition of citrate buffer. In spectroscopy technique ,The concentration of sodium thiopental was quantified by the absorption ratio (A670/A520). Results and discussion Citrate was chosen as the stabilizer for AuNPs because it is negatively charged, and can act as a stabilizingagent to disperse AuNPs in aqueous solutions. The Au NPs after synthesis showed a surface plasmon resonance (SPR) band at 405 nm (Fig. 1a). the addition of sodium thiopental doesn’t led to a color change of Au NPsin ultrapure water, although the thiol group of sodium thiopental tends to readily adsorb onto the surface of Au NPs.The pH of AuNPs solution in present of sodium thiopental is 10.2 and Puntes et al[13]reportedthat the presence of charged molecules insolution may induce NPs aggregation by bridging particlestogether. It was observed that multiple electrostatic interactions between the conjugates mediated by cross-linking species led to an effective strong bond and consequently to irreversible aggregation and precipitation. So that at the given pH value , charge of thiopental can be change and thenthe color of the colloidal thiopental-Au NPs can be changed to blu e (broad band above 600 nm).*Scrutiny of pH/Concentrate diagrams of citrate and thiopental shows that at the pH of between 5 to 7 , charge of citrate and thiopental can benegative and neutralfig S1. But when sodium thiopental add to AuNPs solution, the S- group in the sodium thiopental provides a strong affinity for gold. So that orbital of thiol group of thiopentalinvolved for Au NPs surface and when pH change from 10.2 to 6 , the amino group of the thiopental would be accepted H + and get positive charge. In present of excesscitrate at the pH of 6 , thiopental-AuNPscan be aggregated via electrostatic attraction between the citrate ions and the thiopental. So that in this study we used citrate buffer solutionfor control of pH( in the pH range of 3.0–6.0) and source of citrate (as a bridging factor). The aggregation mechanism of Au NPs is illustrated in Fig. 1. Optimization pH and time we proceeded to study the behavior of the conjugated system by modifying the pH( 7.1-5.4). The pH of an aqueous solution of0.00001M thiopental capped AuNPs was varied by direct addition of 0.05Mcitrate buffer to the solution andThe UV-Vis spectrum wasmonitored and the extinction ratio of absorbance at 600 nm to 420 nm (A600/A410) is plotted against the pH inFig. 3A. The thiopental-capped Au NPs were stable at basic and neutral conditions.When the pH of the solution was below the 6.4 , Au NPs agglomerated.the aggregation was solely due to the bridging citrate between the amine functionality.Onthe basis of this optimization experiment, the pH was set to 6.2 to achieve a best aggregationFig. 3A.When the pH was decreased immediately from 5.4 after the addition of the citrate buffer scatteringwasobserved.Fig. 3A illustrates theabsorption spectra of AuNPs at different pH value. At the concentration of sodium thiopental as 0.00001M, the extinction ratio ofA650/A520 at room temperatureexhibited a rapid increaseduring the first 1.5min,then increased gradually from 1 min to 18 min and then remained constantFig 3B. Thus, the detection time was chosen as 20 min. We choseto use the absorbance ratio at 500 and 600 wavelengths to quantify thecolor of the system,thecolor change at various sodium thiopental concentrations were monitored byUV/Vis spectroscopyfig4A.Quantitative analysis was performed by monitoringthe absorbanceat 1minute after the addition of citrate buffer Fig4B .The linear range, detection limit and reproducibilityof the method were evaluated under the optimumconditions.Thecalibration curve for sodium thiopental was linear in two ranges of( †¦Ã¢â‚¬ ¦. To †¦Ã¢â‚¬ ¦ and†¦Ã¢â‚¬ ¦ to †¦Ã¢â‚¬ ¦) with correlation coefficients 0.9981 and0.9979, respectively. The Experimental detection limit has been obtained as 2 µM. The relative standard deviation(R.S.D.) for1.0Ãâ€"10−8M thiopental measurementwas2.7% (n=11)Fig4A .when thiopental concentrationincreased above 0.0005M, scattering was observed fig3B because thiopental polymerized white citrate molecule. So that we tried paptode techniques to resolve thisproblem FigS1. Although the higher concentrations of sodium thiopental was determined by paptode, but the limit of detection was rather high (LOD 10  µM) in comparison to the spectrophotometric method. The detailed procedure for sodium thiopental determination by the paptode method is explained in supporting information. To test the selectivity of the above method for sodium thiopental, we testing the response of the assay to some potential interference species and structurally similar to the sodium thiopental such as†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.in optimum condition and different concentration .the results areshown in bar diagramFigure 8 .red barsexhibit Color changes of the solution in thepresence of various interference species at concentrations of 10mMand bluebars exhibit Color changes in presence ofinterference species at real concentration in serum ( 1M cysteine, 2M†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦), The maximum absorption wavelength of AuNPs did notchange in the presence of the tested species, Except for cysteineat concentrations of 10mM. Therefore, AuNPs had good selectivity for sodium thiopental detection in optimum condition in the serum. Colorimetric detection of sodium thiopental in serum: To validate the reliability of the proposed method for sodium thiopental detection in real samples, The unknown amounts of thiopental were added to thethree different human serum samples before samplespre-treatment .Detecting of sodium thiopental in a serum is not easy because of the serum constituents.the color of the Au NPs was not stable by the addition of the blank serum. So that it mustdiluted ten times. As regardsthe calibration curve for detection thiopental by this methodand dilution of serum and thiopental concentration in serum as a function of time varies after the usual 4.8 mg/kg induction doses [] , we can detect sodium thiopental in human serumbefore 3 hour.samples were determined by both the AuNP-based method reported herein and the standard addition method. Satisfactory results and recoveries as shown in Table 2. The satisfactory results obtained indicate that proposed sensors can be applied to real sample assays. [1] H. Russo, F.

America The Beautiful :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  A terrible terrorist act was committed on American soil on September 11, 2001. Airplanes were hijacked, taken to important cities, and crashed into important buildings. This dreadful happening shocked all of America. Most are still in denial and grieving over the tragedy. It seemed that America was getting little support from other countries; unlike the support America gives many other nations when they are in trouble. One reporter from Canada, Gordon Sinclair, thought this was a terrible injustice. In a report given by Sinclair, many times America has helped out, even its enemies, were pointed out. Sinclair points out the fact that America has some of the best technology, the fact that America has helped its enemies with restitution after wars and bombings, as well as the fact that America is a watchdog that helps those who have domestic problems.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"You talk about Japanese technocracy, and you get radios. You talk about German technocracy, and you get automobiles. You talk about American technocracy, and you find men on the moon – not once, but several times – and safely home again,† states Sinclair. This statement shows the vast amount of technologies America possesses. Later in the same paragraph, Sinclair remarks about the fact that America did not even pursue its draft dodgers for the fact that they ran to Canada. This shows that America’s domestic problems are not as important as helping others around the world. America lays its scandals on the table for all to view. To speak more on the issue of technology, America is the largest producer of airplanes in the world. America does not boast about its technological advances, it merely allows other nations to share in its glory.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"This Canadian thinks it is time to speak up for the Americans as the most generous and possibly the least appreciated people on the earth. Germany, Japan, and to a lesser extent, Britain and Italy were lifted out of the debris of war by the Americans who poured billions of dollars and forgave other billions in debts,† states Sinclair. This quote refers to the restitution mentioned in the beginning of this expose. After bombing Hiroshima and Nagasaki during World War II, America gave much money to the Japanese to help rebuild their cities. Can a country that rebuilds its enemies be that bad, or is it simple minded and blind? In my opinion, America is just a good neighbor.

green house effect :: essays research papers

GREEN HOUSE EFFECT INTRODUCTION In temperate countries some economically important plants that cannot grow outside at a very low temperature during the winter are grown in glass-walled & glass-roofed growth chambers (known as glass houses)exposed to sunlight. Glass houses are also used in sub tropiacal regions during winter months & relatively cold high altitude for high value horticultural annual crops including flowers on a cmmercial scale as well as for research work especially for breeding of new varities & crop physiological & pathological studies. Temperature within the glass house rises because of the glass of the roof & walls through it allows entry of sunlight with little obstruction,resist the escaping of the reflected light of longer wave-lengths rich in infra-red rays resulting in a heat built up. Such glass houses are called green housesas the light & heat within such houses prove very effective for profuse growth of green plants. The property of trapping heat by carbon di oxide & other gases of the atmosphere is similar to the glass cover of green house that reasists the escaping of heat radiated from inside of the house.As such, these atmospheric gases are called green house gases that resist the escaping of radiated heat from the earth by absorbing infra red rays & particularly reflecting the trapped heat back to earth's surface.this phenomenon is therefore called the green-house effect in wicch certain atmospheric gases act in a manner similar to the glass cover of glass house,as earth itself act as a green-house. MAJOR GREEN HOUSE GASES The major sources of green house gases are (i)CARBON DI OXIDE - It comes from burning of fossil fuels &from deforrestation. (ii)METHANE- It comes from paddy field,burning of wood,wetland etc. (iii)CHLOROFLURO CARBONS -which is populary known as CFC. It comes from air conditioning industry,foam packaging industries. (iv)NITROUS OXIDE-It comes from coal burning,motor veicheles,breakdown of chemial fertilizer,biomass burning. Carbon-di-oxide is the major green-house gas responsible for more than 55% of the green-house-effect. Methane is responsible for 20%,CFC is responsible for 15% & NO is responsible for 5% of the green-house effect. If the amount of carbon-di-oxide & other green-house gases would increase in the atmsphere ,the temperature on the surface of the earth & that of the layers of air adjuscent to the surface would increase,on the other hand global temperature would increase with the decrase in amount of the green house gases in the atmosphere.In fact the amount of all the green-house gase in the atmosphere is gradually increasing, as a result of which it is predicted that the global temperature would increase & there would be climatic changes on the earth resulting in adverse effects on the ecosystem of earth.

lighthod The Nigger in Joseph Conrads Heart of Darkness :: Heart Darkness essays

The Nigger and The Heart of Darkness    â€Å"The Heart of Darkness,† by Joseph Conrad was written in 1898 and 1899 and published in 1902.   So, although it wasn’t surprising that the word used to describe a black person was nigger, it was insulting just the same.   Throughout the short story I had to remind myself of the time period it was written. Joseph Conrad is nothing short of a genius.   His writing technique is eloquent, and surreal and yet after having completed â€Å"The Heart of Darkness,† I couldn’t help feeling a little insulted by the oft used word nigger.   My feelings lead me to do a little research on this word nigger.   I checked three dictionaries:   (1) the â€Å"Oxford Concise Dictionary,† (2) the â€Å"Webster’s Ninth New Collegiate Dictionary,† and (3) â€Å"The American Heritage Dictionary.†Ã‚   They all had in common one definition, â€Å"a member of any dark-skinned race.†Ã‚   In addition, they all said it was â€Å"offensive.†Ã‚   Webster’s went one further and said â€Å"a member of a socially disadvantaged class of persons.†Ã‚   Now this last definition was closer to what my parents had told me the meaning of the word nigger was, an ignorant person.   I tend to like my parents’ definition much better than all the r est combined! The word nigger is actually derived from the Latin word niger which means black.   Okay, so we’re getting closer to understanding now.   So why all the controversy surrounding this word?   I even have to wonder if â€Å"The Heart of Darkness† was written by a black author would I have been equally or less offended?   This word nigger was recently the cause of a controversy between two very prominent directors, Spike Lee (black) and Quentin Tarantino (white), in regards to Tarantino’s new movie â€Å"Jackie Brown.†Ã‚   Lee felt Tarantino used the word nigger too many times in his movie and considered it a racist act.   I’m not sure, but I believe Lee too has overused the word in his movies and yet he publicly cries foul when Tarantino does the same thing.   What makes blacks so offended by whites using the word nigger when they use if themselves? The main reason touted is because some blacks use it (and I mean use it often) as a term of endearment.   Then there are some blacks (usually the upper crust) who use the word as an insult, as in Webster, as a description of a low class black person.

The Diary of Consuelo Ortiga Y Perez

The Diary of Consuelo Ortiga y Perez * 16 September 1882 We have met two more Filipinos; one is called Rizal and the other, Perio. 30 September 1882 Rizal brought me a cane this morning which is full of sugar and one cannot tell how it was put inside. [01] 9 October 1882 Rizal says that he goes out only to go to the medical school and to come here at night. 18 January 1883 Rizal talked with me for a long time, almost the whole night. He told me that I was very talented, that I was very diplomatic, and that he was going to see if he could extract some truth from me within two weeks; that I was mysterious and that I had a veil over my ideas.He asked me who my favorite author was; I don’t know what I answered him because I was no longer feeling well. Lete told him that neither had he understood me and I said that it was easy and I was sure that Rizal would understand me forthwith. Now I’m sorry for having said this. Have I not given him hope with it? Rizal told me that he detested amiable women because when they smiled, men imagined that they did so for something else. As he had told me the night before that I was very amiable, I understood that he meant it and I left him so that he would not make a mistake.A man should first study the ground and if he sees that the smile is fore everybody he ought not to pay attention to her smiles because in distributing them so freely they lose all their meaning. 26 February 1883 . . . Rizal is also in love; he has not declared this but almost, almost. He told me last night that he had a sickness that would not leave him except when traveling and that was only perchanc4. He also told me and I understood why, that two brothers had killed each other because both played the same card, that is, because both loved the same woman.He said that he had taken notice of one who was very tall for him but in spite of the fact that he had done it to amuse himself, it was useless. I listened to him with pleasure because he talks well and I fear that because of that he may think that I’m giving him hope, as it is in reality, but as it happens that I like his conversation, I abandon myself to it and then when he goes away, I’m sorry; he comes and again I do the same thing. Lola [02] was telling me that we ought to go away this summer and I would be glad to see if by not seeing Filipinos; I would avert a tempest that I see is near.I find myself in a position of not knowing which side to take: Lete on one side, Rizal on the other, on another the two brothers; [03] all attack and I have nothing with which to defend myself except my head, for I don’t see, as I go nowhere, my former admirers, though it would be the same should I see them. Those who do not suit me for some reasons, and these neither for others; in short, sometimes I fear I may lose my mind. 2 March 1883 Rizal asked me if I didn’t miss another love. I said to him â€Å"no,† but that is false. For sometime now Iâ⠂¬â„¢m different.Before I didn’t think of things I’m thinking of now. Then I had more suitors than now and I don’t know if for that very reason I didn’t give them altogether even ten minutes. Now, on the other hand, I think of them and my opinion is divided between Rizal and Lete. The first one tempts me by his manner of speaking and because he seems to me a serious lad, though formal ones frighten me. 20 March 1883 Rizal was much preoccupied and I asked him what the trouble was. He said that he was thinking of certain changes. â€Å"You’re sad and here sadness is forbidden to enter. â€Å"It’s true; I’ve been importunate. † â€Å"No; I’ve been the importunate one in saying that to you. † â€Å"I know,† he said to me in reply, â€Å"that some are winning. † At that moment another spoke to me preventing me fortunately from answering. Later he told me that I was giving it for his saint’s day. à ¢â‚¬Å"How? What do you mean? † â€Å"Nothing, nothing; I’ll explain it to you another day. † I didn’t wish to insist. In the afternoon he said to father that he might trouble him to see if he could finish his course this year.It seems that he wants to go away. It is thus like a wound. Poor Rizal! And poor me who inspires love in those whom I can’t love! 2 April 1883 Rizal began to tell me: â€Å"I congratulate you,† but I got only ambiguous phrases from him. At this point Lete was able to sit beside me and said to me: â€Å"Now we are going to adjust our accounts. I’m very much irritated by the philosopher. † (That is what he calls Rizal. ) â€Å"Why? † â€Å"Because he is very attentive to you tonight. Haven’t you noticed a certain change in him? † â€Å"I? No. † Well, he has suffered it greatly; the other day he told me, ‘Don’t you know that I’m getting to like Consuelo? ’ † â€Å"‘Yes? Then I’m glad,’ I replied, and yesterday I went to his house and he was writing some verses. † â€Å"For whom are those verses? † I asked him. â€Å"For a newspaper in the Philippines. † â€Å"Are they, perchance, inspired by the ardent rays of Consuelo’s eyes? † â€Å"Chap,† he replied, â€Å"I don’t need to be inspired. † â€Å"What do you think? † â€Å"That you exaggerate; I don’t believe I’ve such intentions. † â€Å"He’s very clever; you don’t know him. †I laughed to myself, because I know all that by heart. (Here follows a long dialogue with Lete. ) At this point Esteban Villanueva [04] comes and says to Lete: â€Å"Come and close the door for I’m leaving. † He went but on leaving he took the chair with him. Rizal came full of jest and said to me: â€Å"Tell me, Consuelo, why does Lete take away the chair? † â₠¬Å"Ask him. † â€Å"Later,† Lete said to him. â€Å"I'll explain. † Afterwards, Rizal said to me: â€Å"Tonight many will suffer from the lung and the heart. † Then Lete said to me: â€Å"Understand ‘from the lung’ for gambling; from the heart, for you. â€Å"And why give it that interpretation? † â€Å"Because it is his. †I went later to get some copper coins that Antonio (Paterno) had in his vest pocket and when he surprised me, I said: â€Å"What a poor thief I am! † â€Å"You can be sure of that,† said Rizal to me, â€Å"but of another thing no. † This vexed Lete and he and Rizal were peeved all night long. We – Antonio, Rizal, and I – arranged ourselves to play tute [05] and Rizal began to tell me things always circuitously until I told him that he had something that I didn’t like and that is he was not frank enough. You speak in such a way that it’s necessary to think a grea t deal to be able to understand you and I hope that in time I’ll understand you. † He became serious; he put his hand to his forehead and said to me: â€Å"You know very well what I want to tell you, but there’s no better system of avoiding answering then to ask questions; but since you want me to tell you plainly, tell me if it’s true that one who comes afterwards arrives late. † â€Å"What! Have they said that I said it? † â€Å"No; nobody would say it. † â€Å"Then, you ask me if he who comes behind arrives late. †Ã¢â‚¬Å"Yes, that’s it. † If I were to tell you that, I would have to relate to you many things in my intimate life that I’ve told nobody. † â€Å"You’re right, I ask you to excuse me, but as you’re so amiable, I’ve dared† 3 April 1883 My account having been interrupted yesterday, I continue it today. After awhile, Rizal said to me: â€Å"I’m going to tell you a story. † â€Å"Let’s see. † â€Å"She was a girl courted by two men. She was engaged to one and the other would tell her: â€Å"So and So wants to court you† and when he would go away, she would laugh with the other at him. † â€Å"If I could get mad, I would. † â€Å"Why? † Because you’ve called me a coquette. † â€Å"No; because she wasn’t to blame. † â€Å"It was to find out if she listened to both. † â€Å"I didn’t want to say that, nor did the other tell her that he loved her; but at any rate I ask you a thousand pardons and I withdraw whatever was offensive. † I stood up for a moment and when I came back, Rizal, truly pressed, said to me: â€Å"Do you forgive me? † â€Å"I’ve nothing to forgive because it was due to my excessive susceptibility. † â€Å"Why? Do you forgive me? † â€Å"I forgive and see how good I am for I impose no penance. † â€Å"Impose a penance on me,† he said. April 1883 Last night some were absent, among them Rizal, a thing that surprised me. Lete said to me: â€Å"I’ve come more than anything else to ask you a question. † â€Å"What? † â€Å"Rizal told me the other day that last Sunday, speaking with you, you told him that this summer many will be disappointed, and I want to know if I’ll be one of them. † â€Å"Why do you want me to tell you a thing that I don’t know? I spoke without knowing what I was saying. That indeed slipped from my tongue, as I was following my own thought more than the conversation in which I was engaged. â€Å"I don’t understand what you want to say. † â€Å"Well nothing; I said that just to say something and now I’m sorry for I see that my phrases are commented on. † â€Å"When Lete told me this I was displeased that Rizal had told him, but Lete told me later that Rizal told him in order that h e would be warned. I’ve already thought that since Rizal is so astute, he’ll make Lete averse to me to have one rival less. 16 April 1883 Rizal told me he has some plants that he has bought today and that the first flower will be for me.He told Lete and me a story that he said belonged to my mythological times. He calls Papa â€Å"Periandro† and Lete â€Å"Letidolis† and himself â€Å"Planchivis†. He said that Periandro had a daughter to whom Diana had granted the gift of loving all men and afterwards he added women. In short, the story was long and I don’t remember all of it, but in it he spoke of everything and explained our respective situations. 7 May 1883 Last night I was in the corridor when Rizal passed on his way out, but instead of leaving, we talked for more than an hour.He again repeated that he couldn’t understand me, that I had a very black veil that hid my ideas from him, that many times he believed that a thing was done that in reality was not done, and it happened to him when studying that instead of letters he always saw a figure. . . . He brought me a flower, the first that his plant bore. 14 may 1883 (Dialogue between Consuelo and Lete about their engagement) At this point I opened my handbag and I saw the flower Rizal had given me last Sunday and without caring a whit, showed it to him.Everybody knew it and Rizal, however much he tried to dissimulate, was very happy. Afterwards I was sorry but there was no remedy. Lete then said to me: â€Å"You’ve kept the flower. † â€Å"Yes; I was removing things; my handbag was open and I dropped the flower into it just as I would have done with any other thing. † â€Å"You’re a terrible woman,† Rizal said. â€Å"It seems unbelievable! It’s atrocious, with that sweet face you take delight in mortifying; since this night you have made me suffer so much and you do nothing but laugh. † â€Å"I want to laugh n ow if by chance I may have to cry later. â€Å"I would be glad. † â€Å"Thanks,† I said to Rizal. He didn’t know that I was at the point of crying. I don’t remember what Rizal said that Lete said to me: ‘You’ll not make me quarrel with my friend. ’† â€Å"I? Why? † â€Å"Because it’s so. † â€Å"It will not be serious. † â€Å"Who knows, perhaps you will be the first cause. † â€Å"For God’s sake, don’t frighten me for I’m afraid! † â€Å"Lete is so good,† added Rizal, interrupting the conversation. â€Å"One night I gave him such great fright when he was alone at one house that he left so angry that I saw him cry.Nevertheless, the other day, we made up. † â€Å"You have seen me cry? Where? Here in the house? † Lete objected, grateful for that affectionate praise. The other didn’t reply and I became very curious. Have they had some displeas ure between them? 9 June 1883 For two Sundays all the Filipinos haven’t come. Rizal was here the other afternoon and he said he had not come on account of the examinations and that he came out well in every one of them. The poor one is very enthusiastic and I’m sorry. Enthusiasm, they say, is contagious, but I can’t be infected.I’m quite mortified that they have so soon forgotten me for some nobodies [06] who, according to my information, are not even pretty, but I’ll be very careful so that they’ll not be vain thinking of another thing and in case it’s calculation as I imagine. 11 June 1883 Rizal and Antonio (Paterno) who were at the Retiro yesterday brought me flowers and they told me to go there, but I haven’t gone because those girls go and I don’t want to be obliged to speak with them. Rizal told me he was going to Paris to distract himself, to cure himself of an illness contacted a year ago.Then he has seen others deceived by the amiability with which they have been treated and he was afraid the same thing might happen to him; that he fell in love again and it seemed to him that he was going to be accepted and soon he was disappointed. Now it’s different because she belongs to a much higher class. â€Å"I have,† he said to me, â€Å"too many aspirations. † â€Å"Man must always have them. † â€Å"Yes; but when they’re too high they’re ridiculous. † â€Å"An aspiration is never ridiculous when its end is good and neither do I believe that you have aspired for the moon. â€Å"No; but it’s so difficult that I know it will accept only one with a great name or high position. † I didn’t answer him. What could I say to him? If I gave him hope, then later to tell him â€Å"no† would be a crime; and I haven’t enough willpower to take all hope from him, because, despite everything, I like him. â€Å"Tell me what you w ant from Paris. † â€Å"Nothing, may you enjoy much. † â€Å"You already know that I’m going to study French, and what I’ll try is to get curried if I don’t succeed. I’ll follow the currant. Lete and I have concluded a truce for the summer. â€Å"We’re in it,† I said to him. â€Å"When does it end? † â€Å"In September. †Ã¢â‚¬Å"Then on the day following, the end. † â€Å"In October? † I asked, knowing what he wanted to say. â€Å"Yes. † â€Å"And what’s it, in what does it consist? † â€Å"Pardon me, for as it’s Lete’s also, I can’t tell you. † â€Å"Don’t say it then. † 18 June 1883 Rizal has gone to Paris; he says he’ll come back in September. Last night Antonio (Paterno) told me that as the train moved, he sent us many regards through him. Will he get cured? 23 August 1883 The other night Lete told me that on Monday he talked wit h Rizal for more than four hours. As a good friend,† he said, â€Å"I related to him everything, and now he saw that I had not been sincere towards him. † Before, Rizal said to him, he didn’t think of me, now the told him the opposite. Rizal asked him about the status of his relationship with me. He told him and he advised Lete not to go to Barcelona because â€Å"If you go,† he said, â€Å"it’s possible she may not answer you on the 24th but on the 25th, or never, which is the same; then, as soon as you’re away she’ll get cold, in case she’s becoming convinced, and as for me I can’t be responsible to you.â€Å"You know,† Rizal continued, â€Å"that I liked Ines and nevertheless I left her to Antonio (Paterno); with her I could have passed away the time, but with Consuelo no; for this reason I have told you as a friend I advised you to marry her, but as Rizal, no. † â€Å"As he’s noble,† Lete continued, â€Å"we have made a pact that he’ll say nothing until 24 October. He told me he had to answer a question you put to him. I asked him wit it was but he replied that he couldn’t tell me because it was a secret. The following day Rizal came and brought two music sheets as a souvenir from Paris and some verses that I had asked him at the concert and others dedicated to me [07] which confirmed everything Lete had told me.They go with this diary to save me the trouble of writing them down and because I believe they reveal passion, not for an indifferent one but for me who had inspired them, and for knowing their author. My question was if he already got cured, a rather bold question which I’m sorry I asked. 3 September 1883 I showed Rizal’s letter to Matilde. [08] She didn’t like it and said there was a very bad intention in the polite piece. 0 October 1883 All the Filipinos came last night. Lete told me that he had asked Rizal what we were going to talk about, and replied that it was nothing. And he added: â€Å"Is it you who have to talk with him? † Yes,† I answered, â€Å"what I regret is that you have told him; I’ll not say anything to him again. † â€Å"I, too, am sorry, but now nothing can be done. † As Rizal was warned by Lete, several times he spoke to me and asked me as formerly if I would win in the game but I didn’t want to have a conference with him to show Lete I was not interested and, besides, it was already becoming difficult.I went with Papa yesterday to see the king returning from his excursion. The enthusiasm was great. . . . We were also carried away in that surge and when it cleared a little I heard a voice telling me: â€Å"Over here, Consuelo. † It was Maximino (Paterno) who was with his brother, Ventura (Valentin), and Rizal. The last asked me if I knew why all were so studios. â€Å"Because they have realized the evil they were doing and they abj ured their errors. † â€Å"No; because they have learned that it’s a prerequisite to certain things to have a career and for that reason they study in order to aspire for them. We talked a great deal and I don’t remember everything. â€Å"If I believed in certain things,† I continued, â€Å"I would say that you’re immortal. † â€Å"Immortal? † â€Å"For many things. † â€Å"For none I believe; it seems to me that I’ll die soon and if one thing that I’ve thought of and I haven’t told anybody occurs, I’ll notify you wherever you may be to show you I’m right. †Ã¢â‚¬Å"I’ll note down what you have told me as soon as I get home. † What interpretation had he given to my words? Later he told me that he believed in nothing, that he had no faith. â€Å"And how can you live? † â€Å"Without it. â€Å"On the contrary I think we ought to believe in something that may encourage us in our undertakings and may comfort us in our misfortune. † â€Å"When a curate says it, I don’t believe it; if you should say it, I would believe it. † â€Å"God grant that I may have power to make you believe! † He kept silent and after awhile he said to me: â€Å"Neither do I believe in the love of parents; mine love me, but they would not remember me if I would not return or I’m delayed ten years in returning. † â€Å"Don’t say that; I believe little and if you speak to me thus, I’ll believe in nothing.The love of parents doesn’t die. † â€Å"I’ve not been a father, undoubtedly for that reason. . . .† â€Å"I neither, but I judge filial love by the paternal. I’ve separated from Papa for some twenty days and when the train left I was very happy. . . . It seemed to me I was going back home at night, but upon arrival at the town where I was going, despite my efforts and I’m not give n to tears, I couldn’t control myself and I cried . . . and everyday I remembered him. † â€Å"You must have been alone. † â€Å"No; my brother was with me. † â€Å"We don’t speak of those loves. And the others? â€Å"Oh, we are agreed on those. † When I was small I heard it said that friendship couldn’t exist between two boys, and I said: What has distinct sex got to do with it? I wished to try the experiment and I see it’s true. I believed in a friend, nothing more than a friend, and we broke up quarreling. †Ã¢â‚¬Å"I would be yours if that wee not too much for me, I can’t aspire. . . .† â€Å"And if it’s granted to you? † They interrupted us in order to cross the street, and then Sanmarti, [09] whom we met, stood beside me. Rizal also asked me what I would say if Lete would ask me how I spent the day. The truth,† I replied. â€Å"Then, I’ll tell him that I spent it very well, and then I saw the Queen and the King. † â€Å"You’ve been more fortunate than I,† I said to him as if I didn’t understand him. † â€Å"The Queen was beside a gentleman [sic.! ]. . . .† It seems to me Lete would not be very much satisfied for God knows what Rizal would tell him. When all had left, Rizal told Papa for me to hear: â€Å"Spain ought to ally herself with another nation. † Papa: â€Å"No sir; Spain is all right as she is. †Rizal: â€Å"It’s time she ceases to be a second class power. Papa: â€Å"You know Spain’s history, therefore you know that whenever she allied herself with other powers she lost rather than gained. † Rizal: â€Å"However, an alliance with a young, rich, and strong nation, I believe, in the present circumstances and even in the future must be beneficial to her, though it may be only a support that a weakened monarchy needs. . . .† â€Å"Weakened? How? Never has it rested o n a more solid foundation; never was it more loved by the people that see in it the symbol of regeneration, of peace, of new life. Rizal: â€Å"Right, Don Pablo, but only in form, not at the bottom, as it represents the symbol. The people, as part of it, loves the monarchy per accidens, [Contingently, indirectly, by virtue of some chance, circumstance, or happening. Latin for, by happenstance. Opposite of per se. – rly] because it represents the peace of Spain which it loves per se, because it still believes in that longed-for regeneration of its past grandeur; but the primates of the people adore above all someone who is determined to take possession of her with the same purpose of governing her.

Proposal to Eliminate Obesity

Ste wart, M. June 13, 2011 Eng-106 Proposal to eliminate fleshiness The stir against fleshiness is an ongoing contest peoples all over the sphere are struggling to lose saddle. Obesity is star of the most leading manages of death ecumenic this disease causes life threa cristaling wellness conditions, such as high profligate pressure, cardiovascular diseases, type 2 diabetes, arthritis, forty winks apnea, strokes and cancer. The number of rotund individuals through out(a) the world has doubled since three decades ago, which has become a high risk wellness component part in todays society.Recent studies designate that one out of e real ten individual worldwide has been diagnosed as be obese. Despite the increasing corpulency dilemma, studies augur that some stretchs find it hard to speech weight issues with obese patients. Although, the touch and patient cope there is a puzzle, incomplete is willing to discuss it. This only makes the problem more complex la ter on, when it could arrest been resolved in the early stages. William, Bestermann jr. , a medical director for Holston medical exami country Group in Kingsport, Tenn. accedes that if doctors are committed to keeping patients from having strokes or heart rapes, whence this conversation can non be avoided, and they have to military service their patients lose weight. Bestermann has developed a excogitate for doctors to foster guide and successfully discretion obese patients on a delegation for the Stop Obesity/Alliances, which consist of captain businesses, health apprehension providers, unions and insurers whose sole purpose is to strategize an attack on obesity. Doctors have centered the fight against obesity, in an effort to win the war on obesity.Medical advisors suggest that primary care doctors launch a well-developed attack against obesity, in regularize to expand their patients lifespan due to the concomitant that it decreases their tone of life and also acc ounts for snootions of dollars in health expenses. The most common reason for the excessive increase in health expenses there are near s stock-stillty-two one million million million peoples in the United States who are obese, which enhances an development of chronic health conditions associated with obesity. If doctors and health indemnity companies work together to discover an sound solution to eliminate obesity, this would save billions of nnocent lives. duty tour methods to assistant in the fight against obesity are inevitable due to the return circumstances. The Staff at the Mayo Clinic state that the purpose for obesity interference is to succor individuals reach and keep a ample weight. A person seeking considerment should be monitored by health professionals, therapist, nutritionist, dietician, and an obesity specialist in an effort to watch a healthier lifestyle. Obesity is a life dark disease that causes early(a) respectable chronic diseases if not enured properly.Most peoples become obese by no fault of their own, due to psychological problems, recollective illnesses and other distressful aspects in their life. My eat up based on my research is that prexy Obama, recounting and Healthcare Professionals should rejoinder a stand on this life threatening disease as soon as possible. The president can only do so much if sex act does not approve a bill. It is a tragical to see so m both peoples in this world suffering and dying from any kind of disease that is in fact preventable. Obesity being one of them should be at the top of the list, because it is the main cause of all these other incurable diseases.If preventing or ridding the world of obesity is the key to best health, and expand a persons lifespan. Why has Congress done something roughly it? Are doctors really concerned about their patients health? Some of our kids are even obese obesity is a serious condition that most of us knock off to realize. How can we say that, America is the reason of the proud and the brave, if we as peoples of this great nation refuse to come together and take a stand on what is the right way? Obesity is an ongoing war that has hindered and outlined our society far too long it is time that we do something about this crisis, in advance it is too late.And our society becomes extinct. Peoples of this great trim prat take a stand, in order to make a change we must come together. I am a firm believer in change, thereof by the will of God and myself, I will address President Obama and Congress on this issue to fight obesity starting today, because tomorrow is not promised to you or me. We have to live for today and help others in the process, who are unable to help themselves. I find this to be very disturbing that so many peoples in the world are obese. And nothing is being done about it. Society what has happened to us?Will we continue to sit back and do nothing? Even if Congress have to pass a bill for an effective method to fight obesity, than they should. For every man, woman and child that are diagnosed as obese, effective immediately they should be offered weight-loss surgery. galore(postnominal) in the past have died because they were obese this is not something Congress does not chicane about. Some obese individuals reach out for help from their physicians the answer to their consistent weight gain problem is to stop eat or exercise more. This is the solution to end obesity, not applicable.Are doctors failing to save lives? Do they offer the best health advice to patients? I have to admit a doctors job seems a precise overwhelming, with the enormous amount of patients that they see and treat daily, but if you cannot trust your own doctor in regards to your health issues, who can you trust. If doctors know of any cures to save millions of lifes yearly. Are they entitled to share their findings with patients? References Greene, C. , & Hellmich, N. (2009, October 06).
