Albumin as an outcome measure in haemodialysis in patients: the effect of variation in assay method. (1/38)

BACKGROUND: Serum/plasma albumin is an important predictor of future mortality/morbidity in haemodialysis (HD) patients and has been proposed as an important audit measure. Different methods of albumin assay give different results and the bias between methods may be greater in renal failure patients. METHODS: Albumin concentration in plasma was measured by three methods, two dye-binding methods (bromocresol green (BCG) and bromocresol purple (BCP)) and an immuno-turbidimetric (ITM) method, in 143 HD patients (group I) and 49 non-renal patients (group II). Comparisons were made between means, variation in differences across a range of albumin concentrations and on the percentage of patients within the normal range. RESULTS: In HD patients (group I), BCG over-estimated plasma albumin compared with the other two methods. The difference could be as much as 10 g/l and was more marked in hypoalbuminaemic patients. The BCP method gave results closer to the ITM method, particularly in HD patients. These differences were less marked in group II patients but both methods overestimated albumin compared with the ITM method. Using the BCG local laboratory normal range, 84% of HD patients had plasma albumin concentrations within the normal range but this fell to 57% if the BCP results were used. CONCLUSIONS: The method for determining albumin concentration has a marked effect on the results particularly in HD patients. BCG, the most commonly used method, gives higher results than other methods and correlates poorly with an immunological method. These differences make comparative audit between nephrology units difficult and have implications for other biochemical variables and other specialties.  (+info)

Conversion between bromcresol green- and bromcresol purple-measured albumin in renal disease. (2/38)

BACKGROUND: Albumin measured by a bromcresol purple dye-binding assay (Alb(BCP)) agrees more closely with the gold standard of immunonephelometry than does bromcresol green (Alb(BCG)) measurement. Both tests are in current clinical use. A method for converting between the two would be useful. METHODS: We measured albumin by bromcresol green and bromcresol purple in 535 patients, 155 of whom had renal disease. We randomly divided data from the patients with renal disease into two equal-sized sets, and used one set to derive, and the remaining set to validate, a regression equation relating the two values. RESULTS: The relationship Alb(BCG)=5.5+Alb(BCP) performed very well in both the renal patient validation set and in the data from 380 unselected in-patients and out-patients. Intraclass correlations for agreement between measured Alb(BCG) and predicted Alb(BCG) was 0.98 in both analyses. CONCLUSIONS: The ability to convert between these measurements will be of use in clinical situations where the absolute value of the serum albumin is important, when data from laboratories using different methodologies must be combined, and in the application of the Modification of Diet in Renal Disease formula to estimate glomerular filtration rate in patients whose albumin has been measured by bromcresol purple.  (+info)

Guidance for selecting the measurement conditions in the dye-binding method for determining serum protein: theoretical analysis based on the chemical equilibrium of protein error. (3/38)

A methodology for selecting the measurement conditions in the dye-binding method for determining serum protein has been studied by a theoretical calculation. This calculation was based on the fact that a protein error occurs because of a reaction between the side chains of a positively charged amino acid residue in a protein molecule and a dissociated dye anion. The calculated characteristics of this method are summarized as follows: (1) Although the reaction between the dye and the protein occurs up to about pH 12, a change in the color shade, called protein error, is observed only in a pH region restricted within narrow limits. (2) Although the apparent absorbance (the absorbance of the test solution measured against a reagent blank) is lower than the true absorbance indicated by the formed dye-protein complex, the apparent absorbance correlates with the true absorbance with a correlation coefficient of 1.0. (3) At a higher dye concentration, the calibration curve is more linear at a higher pH than at a lower pH. Most of these characteristics were similarly observed experimentally in the reactions of BPB, BCG and BCP with human and bovine albumins. It is concluded that in order to ensure the linearity of the calibration curve, the measurement should be performed at a higher dye concentration and sufficiently high pH where the detection sensitivity is satisfied.  (+info)

Screening for albuminuria: a case for estimation of albumin in urine. (4/38)

The usefulness of bromcresol green for estimating albumin in urine was evaluated by comparison with the Laurell "rocket" technique. In contrast to the bromcresol green method applied for urinary albumin, rather doubtful results were obtained with conventional (Microzone) electrophoresis for albumin and with precipitation techniques for total protein estimation. Albumin estimation with bromcresol green is recommended as a more reliable substitute for total-protein estimations in urine. Limitations of bromcresol green are also pointed out.  (+info)

Expression of PGT in MDCK cell monolayers: polarized apical localization and induction of active PG transport. (5/38)

The PG transporter (PGT) is expressed in subapical vesicles in the kidney collecting duct. To gain insight into the possible function of the PGT in this tubule segment, we tagged rat PGT with green fluorescent protein at the COOH terminus and generated stable PGT-expressing Madin-Darby canine kidney cell lines. When grown on permeable filters, green fluorescent protein-PGT was expressed predominantly at the apical membrane. Although the basal-to-apical transepithelial flux of [(3)H]PGE(2) was little changed by PGT expression, the apical-to-basolateral flux was increased 100-fold compared with wild-type cells. Analysis of driving forces revealed that this flux represents PGT-mediated active transepithelial PGE(2) transport. We propose that endogenous PGT is exocytically inserted into the collecting duct apical membrane, where it could control the concentration of luminal PGs.  (+info)

Measurement of serum albumin by capillary zone electrophoresis, bromocresol green, bromocresol purple, and immunoassay methods. (6/38)

BACKGROUND/AIMS: The introduction of capillary zone electrophoresis (CZE) to this laboratory has highlighted discrepancies in albumin measured on an Abbott Aeroset by bromocresol green (BCG) and that calculated by CZE on the basis of total protein measured by Biuret. METHODS: This study examined differences in albumin estimation by CZE, Abbott Aeroset BCG, and Aeroset bromocresol purple (BCP), and compared these with albumin estimated by Beckman Array immunoassay. RESULTS: Altman and Bland analysis of results showed a positive bias of BCG with CZE (4.51 g/litre; 95% limits of agreement, 3.77 to 5.26; n = 72) and BCP (3.85 g/litre; 95% limits of agreement, -1.42 to 9.12; n = 72). CZE and BCP agreed closely (0.67 g/litre; 95% limits of agreement, -4.39 to 3.06; n = 72). Analysis of 57 of those samples in which BCG and CZE differed > or = 5 g/litre showed a positive bias of BCG with immunoassay (8.35 g/litre; 95% limits of agreement, 1.54 to 15.16; n =57), with good agreement between CZE and immunoassay (-0.44 g/litre; 95% limits of agreement, -2.82 to 1.94; n = 57). CONCLUSIONS: BCP is superior to BCG for the assay of albumin and has replaced BCG as the routine test for albumin in this laboratory.  (+info)

Theoretical analysis concerning the characteristics of a dye-binding method for determining serum protein based on protein error of pH indicator: effect of buffer concentration of the color reagent on the color development. (7/38)

In the dye-binding method based on protein error of a pH indicator, the color development has been reported to be markedly affected by the buffer concentration of the color reagent. In this study, the author analyzed this phenomenon by a theoretical calculation based on the chemical equilibrium of protein error. The calculation was performed on the assumption that both the dissociated dye anion and the anion contained in the buffer solution react with protein, forming a dye-protein complex and an anion-protein complex, respectively. The calculated results were compared with those obtained by the experiments using bromophenol blue, bromocresol green and bromocresol purple that are employed widely for determining the human serum albumin concentration clinically. The calculated results of this method are summarized as follows: (1) the color development decreases with the increase in the concentration of the anion contained in the buffer solution; (2) the calibration curve is more linear in the higher concentration of the anion than in the lower one. These calculated results agreed well with the experimental ones. From these results, it was concluded that the change in the color development by the buffer concentration of the color reagent is due to the change in the concentration of the buffer anion.  (+info)

Inhibitors of prostaglandin transport and metabolism augment protease-activated receptor-2-mediated increases in prostaglandin E2 levels and smooth muscle relaxation in mouse isolated trachea. (8/38)

Stimulants of protease-activated receptor-2 (PAR(2)), such as Ser-Leu-Ile-Gly-Arg-Leu-NH(2) (SLIGRL), cause airway smooth muscle relaxation via the release of the bronchodilatory prostanoid prostaglandin E(2) (PGE(2)). The principal aim of the current study was to determine whether compounds that inhibit PGE(2) reuptake by the prostaglandin transporter [bromocresol green and U46619 (9,11-dideoxy-9alpha,11alpha-methanoepoxy PGF2alpha) and PGE(2) metabolism by 15-hydroxyprostaglandin dehydrogenase (thiazolidenedione compounds rosiglitazone and ciglitazone) significantly enhanced the capacity of SLIGRL to elevate PGE(2) levels and produce relaxation in isolated segments of upper and lower mouse trachea. SLIGRL produced concentration-dependent increases in PGE(2) levels and smooth muscle relaxation, although both effects were significantly greater in lower tracheal segments than in upper tracheal segments. SLIGRL-induced increases in PGE(2) levels were significantly enhanced in the presence of ciglitazone and rosiglitazone, and these effects were not inhibited by GW9662 (2-chloro-5-nitrobenzanilide), a peroxisome proliferator-activated receptor-gamma antagonist. SLI-GRL-induced relaxation responses were also significantly enhanced by ciglitazone and rosiglitazone, whereas responses to isoprenaline, a PGE(2)-independent smooth muscle relaxant, were unaltered. Ciglitazone and rosiglitazone alone produced concentration-dependent increases in PGE(2) levels and smooth muscle relaxation, and these responses were inhibited by indomethacin, a cyclooxygenase inhibitor. Bromocresol green, an inhibitor of prostaglandin transport, significantly enhanced SLIGRL-induced increases in PGE(2) levels and relaxation. Immunohistochemical staining for 15-hydroxyprostaglandin dehydrogenase was relatively intense over airway smooth muscle, as was staining for the prostaglandin transporter over both airway smooth muscle and epithelium. In summary, inhibitors of PGE(2) reuptake and metabolism significantly potentiate PAR(2)-mediated increases in PGE(2) levels and smooth muscle relaxation in murine-isolated airways.  (+info)

People can still cope in these ways, or with their modern communication equivalents; however, these newer modes of communication require significantly less effort and lets face it--why not go with the easier path? Moreover, the speed of our ability to express ourselves, and obtain a response, is much faster. This speed can be a good thing, minimizing the time that people experience discomfort without relief. But it also has a downside: People have less experience or practice managing their emotions without acting on them rapidly. Unfortunately, the instant aspect of these communications seems to discourage deep reflection and encourages immediate reaction, leading instead to simple venting or "look at me" type communications-profile updates and photos, comments on blogs or websites, and youtube videos-that are less an attempt to share considered, reflective thoughts and images ...

And a lot of people would find, themselves, that work is the kind of default setting: that you need to work and you need to make money and that I have to be intentional about not working. I think that maybe the invitation here is to think inversely. Its actually good to be intentional about when you work. And that does mean stopping at the appointed time.. But it also means being very focused during the times that you are working. I think for me it is easier to break this up into bite-sized chunks throughout the day. So I might say, "Ok that between 8 and 9, Im working on this," and thats what I do during that time. Its making time to work: it has a beginning and an end, and even if the project is not done at 9 oclock, ...

Allergic sensitization to flea bites follows a definite and char-acteristic sequence. Initially, there is no reaction. Sensitivity develops suddenly, usually several days later. Original bite sites, heretofore quiescent, may erupt into firm bumps (delayed re-action). Then comes a period when the firm bumps develop about twenty-four hours after new bites. Immediate reactions (wheals within thirty minutes of the bites) begin to appear and the delayed reaction gradually fades away. The wheals of the immediate reaction resolve within a few hours, while the bumps of the delayed reaction last several days. A period of immediate reactions alone follows. Finally, a state of immunity is reached in which there are no reactions at all. This chain of events is remini-scent of the sequence seen with mosquito bites ...

Finally a doctor had me pulled aside for my Ultrasound / NT Scan. Not the U/S tech, the actual doctor! Everyone was really being nice, including her. Then during the scan she just stopped and turned to face me. She said "This is not a good day for you." My immediate reaction was that they still couldnt get a good read. (This was our 2nd attempt.) That wasnt it. NT is a collection of fluid at the back of the babys neck. She went back to the view... it had been large enough that I hadnt even recognized it. This is where the tears began. I just lay there... holding Elmos hand, crying ...
I HAD to pull away to survive. Seeing pregnant women or newborns was like torture. But now, Im faced with that again. Im faced with watching people that Im walking with find out that their pregnant while I continue to struggle. My immediate reaction was that oh darn, now I cant be friends with them anymore. But after I really thought about it, I discovered that I didnt really feel that way anymore. I think that Im in a place in my life now where I can enjoy watching everyone else as they are blessed by a new baby. Even if my womb is still empty. It makes it a heck of a lot easier to be happy for them knowing that they came from a place where Ive been. Not just another friend or family member that got pregnant and has no idea what its like to lose a child ...
What CAUSES the immediate release of carbon dioxide in carbonated beverages when salt is added? My science fair experiment is measuring CO2 in 3 different soda pop brands. T he experiment calls for placing salt in a balloon and tipping the balloon to add to the bottle of soda. The release of CO2 is immediate, and I measure the balloons. I need to know what has occured that causes the immediate reaction. I have been unable to find the answer in my resources. I need this answer in case the judges ask me. ...
As spring enters the year with blossoms and brilliant sunshine and people enjoying the beach again (well, I do live in southern Spain...), I contemplate my life. A friend recently wrote to say what an awful year this has been for him, and for so many due to the recession, due to numerous other factors, both global and personal ... but mainly outer factors. The comment stopped me in my tracks, because I feel quite the opposite. Its been a year filled with infinite richness, with growth, insights, joy, happiness, excitement, successes, and fascination. Another friend wrote to say she was sorry I had not been having a good beginning to this year due to some logistical delays, but my immediate reaction was that it has been an excellent year so far, notwithstanding these delays, because of the richness of my inner life that translates itself to the outside, and more specifically, to how I view what is going on on the outside. ...
When I heard that Gary Neville had taken the job at Valencia my immediate reaction was it was a good decision - but also a brave one.
On Meatspace Trolling. Upon being summoned for federal jury duty, my immediate reaction was not irritation, but amusement. Jury duty is an opportunity to play a game: the Peremptory Challenge Challenge! When one reports for jury duty, it is of course with the goal of having a "peremptory challenge" used to exclude one from the jury - that is, inducing an attorney to use one of his "get rid of this juror free" cards, as my friend Thi achieved in part by dropping an e-bomb[1] when asked to explain what he did for a living. Getting knocked off "for cause" is easy, and will result from being too heavy-handed in ones approach, so obviously the result of a challenge for cause is ignominy. Being placed on a jury is a form of losing, but then one faces the Jury Nullification Challenge (particularly on a drug jury). The path of glory is clearly to be excused on a peremptory challenge if at all. "So basically, youre trolling the District Court," is how my husband puts it. Yes! Yes, I am! But this is ...
Immune System Chaos: Take a look at what anxiety does to your body and whether its only your immediate reaction to stress or a long-term problem.
Like most people, former representative Ron Paul (R., Texas) learned the details of the federal governments far-reaching surveillance program when he read about it over the weekend. But as someone who has spent the last several decades warning of governments encroachment on civil liberties, he wasnt exactly shocked by the revelations.. "The thought of our government doing this wasnt a bit of a surprise," he tells National Review Online. "I assumed they had been doing it. Theyve had the authority to do it. I said thats what the Patriot Act would end up doing.". At the very least, the official documents leaked by Edward Snowden, a former intelligence officer and Ron Paul donor, offered "credible evidence" that confirmed Pauls suspicions. "I didnt know the details before," he says. "My immediate reaction was, you know, were supposed to be shocked by this?" Surely Paul must feel vindicated, after years of having his concerns largely dismissed by politicians in both parties. Right?. Not ...

The introduction of penicillin for treatment of bacterial infections in the 1940s was immediately followed by reports of allergic reactions. From a clinical view, penicillin allergic reactions can be classified as either immediate reactions occurring within one hour after the last penicillin administration, or as non-immediate reactions occurring at any time from 1 h to 48 h (5). Immediate reactions are usually IgE-mediated while non-immediate reactions are often induced by sensitized T cells. The longer the time before symptoms appear, the greater the possibility that a non-IgE mediated mechanism is involved. Immediate reactions are manifested clinically by urticaria, angioedema, rhinitis, bronchospasm and anaphylaxis. The main non-immediate reactions are maculopapular exanthema and delayed urticaria/angioedema.. The most comprehensive study on the performance of penicillin ImmunoCAP so far is the evaluation by Blanca and co-workers, who studied 129 patients in five groups. In the group with ...

In stoichiometry calculations, we assume that reactions run to completion. However, when a chemical reaction is carried out in a closed vessel, the system achieves equilibrium. Equilibrium occurs when there is a constant ratio between the concentration of the reactants and the products. Different reactions have different equilibria. Some may appear to be completely products, however, all reactions have some reactants present. A reaction may look "finished" when equilibrium is reached, but actually the forward and reverse reactions continue to happen at the same rate. A reverse reaction is when the written reaction goes from right to left instead of the forward reaction which proceeds from left to right. This is why equilibrium is also referred to as "steady state".. It is possible to write an equilibrium expression for a reaction. This can be expressed by concentrations of the products divided by the concentration of the reactants with the coefficients of each equation acting as exponents. It is ...

Im sitting here watching Sigve sleep, and thinking how strange it is to see him in this situation. Up until 1 year ago, when he had the leg infection that turned out to be how the leukemia was discovered, he had never been sick, except for one night in hospital years ago with some stomach cramps, and the odd cold and flu. And I guess its the abruptness of the situation that is weird. Weve known for a few months that he would have to have the transplant, but he never felt sick! And we have often commented on how strange it is to have to be made very sick to get well. But I guess sometimes its like that, it gets worse before it gets better! So far I have found it easy to stay strong; sometimes drawing on Sigves strength, as things have been going so well. He has always had this amazing ability to be able to adapt to any situation, and make the best of it. He told me that when he was told that he probably had leukemia, his immediate reaction was a feeling of gratitude for how good his life has ...
The people he did this to were not all young and powerless or those in his employ whom one can understand being reluctant to report this behavior for fear of repercussions. Among them were "a retired Navy rear-admiral, a dean at San Diego State University, the head of the Port Tenants Association and a businesswoman." So why did they not speak up immediately? Gilberts use of the phrase "I didnt want to make a scene" gives us a clue as to how people like Filner get away with their behavior for so long without the victims blowing the whistle. They take advantage of the fact that they know that most people try to avoid making a scene, especially if they are taken by surprise. I can imagine that the immediate reaction would be shock and disbelief that such a thing could happen. This would be followed by the desire to escape the situation as quickly and quietly as possible without anyone else noticing, out of sheer embarrassment, and maybe having a vague feeling that they might be blamed for the ...
We explored the functions of team monitoring and talking to the room (undirected talk to relay relevant information or comment on the performance of real-time self behavior) for effects on team interaction and performance in 27 anesthesia teams in the clinical setting. Immediate reactions to team monitoring and talking to the room were investigated by means of lag sequential analysis. As expected, we found that in high performing teams, immediate consequences of team monitoring were speaking-up and providing unsolicited assistance. Talking to the room led to further talking to the room and substituted explicit coordination. The results highlight the relevance of team monitoring and talking to the room for team coordination and performance in dynamic healthcare environments. ...
It was as if a searing knife had been thrust into Blaines eyes. But it wasnt all at once, no - it was a dull, searing pain that pulled Blaine out of the darkness into consciousness. His immediate reaction was to bring his hands up to his face, rub his eyes, make the pain go away, but his arms felt so heavy.. A soft voice reached his ears, saying his name over and over. "Kurt," he croaked out softly, turning his head in the direction of the voice. His head hurt so much, his eyelids felt so heavy, but he needed to hear that voice.. "Yes," Kurt said softly, his voice thick, "Blaine! How do you feel? I should get the nurse-". "No," Blaine mumbled, "M fine. My head hurts, though...". "I bet it does, baby," Kurt smiled weakly as he sniffed, rubbing his nose. He reached out to grasp Blaines hand, patting it nervously. "I just want you to know everyones outside. Theyve been here all night. Well except for Sebastian," Kurt said, venom in his voice. "He ran, the coward...But- but we called the cops ...

My most immediate reaction to the article was to find out what she looks like. I make no apologies. Im a compassionate progressive, but Im not a politically correct compassionate progressive.. As I suspected, she looks extremely physically fit, but also attractive and traditionally "feminine". I suspected that for a variety of reasons. First of all, the whole situation of being hassled by intimidated sexists for being "masculine" suggests that the woman in question is likely to be attractive. If a less attractive woman succeeded in the same sport, sexists would merely sneer at her appearance rather than getting worked up. Second of all womens weight lifting is pretty heavily drug tested, and although there probably are athletes who test the limits of that testing (as in any relatively major sport), quite bluntly, it would mainly be contenders for the gold from countries with major weight-lifting programs, a group which does not include the UK, who would be most likely to do that.

To know the exact diagram represent the effect of catalysis on chemical equilibrium, I searched on experimental data but I cant find suitable data. so I consider a hypothetical reversible first -order reaction in each direction where $$\ce{ A ,=, B}$$ I choose those two equations for reversible first- order reaction to calculate the concentrations of product and reactant at a different time: $$\ce{[A]}=\frac{k_b +K_fe^{-(k_f+k_b)t} }{k_f+k_b}{[A]_0}$$ $$\ce{[B]}=\frac{k_f -K_fe^{-(k_f+k_b)t} }{k_f+k_b}{[A]_0}$$. Starting with A at a concentration$[A]_0={0.6}$ and the values of the rate constants of uncatalayzed reaction are $k_f=3s^{-1}$ and $k_b=1s^{-1}$. and the values of the rate constants of catalayzed reaction are $k_f=6s^{-1}$ and $k_b=2s^{-1}$. I did the calculation using excel sheet and draw the graph of concentration Vs time : ...
Equilibrium chemistry is concerned with systems in chemical equilibrium. The unifying principle is that the free energy of a system at equilibrium is the minimum possible, so that the slope of the free energy with respect to the reaction coordinate is zero. This principle, applied to mixtures at equilibrium provides a definition of an equilibrium constant. Applications include acid-base, host-guest, metal-complex, solubility, partition, chromatography and redox equilibria. A chemical system is said to be in equilibrium when the quantities of the chemical entities involved do not and cannot change in time without the application of an external influence. In this sense a system in chemical equilibrium is in a stable state. The system at chemical equilibrium will be at a constant temperature, pressure (or volume) and composition. It will be insulated from exchange of heat with the surroundings, that is, it is a closed system. A change of temperature, pressure (or volume) constitutes an external ...
Le Chateliers Principle can be used to predict how a change in condition affects a chemical equilibrium. Essentially, if there is a change in either the concentration of reactants/products, temperature, volume or pressure, the chemical system will try to respond by counteracting this change and establishing a new chemical equilibrium. This principle can be illustrated in the Haber process:. N2 + 3H2 ,-, 2NH3. For example, if the concentration of NH3 decreased suddenly, the system would try to counteract this change by increasing the concentration of the product. It can do this by shifting the equilibrium of the reaction to the right, by essentially using more reactants to turn into product.. Such a principle can and has been manipulated in chemical industries, such as in the above example, to improve the yield of a certain product. So by removing NH3 continuously, the chemical equilibrium will respond to this by generating more ammonia. This ammonia is then removed, and the system generates ...
Since I was only able to test the mockup with one person I contacted an expert to give his opinion on the application and check whether this can be used by most of the persons with a mental disability. When I showed the application the immediate reaction was really positive. He thinks this application can really be a way to close the social gap some more for a lot of people with a mental disability.. For the dilemma for the selection of text and then reading it out loud or the other way around the expert responded that it might be better to choose for first selecting and then reading it loud because in this way it is consistent with other reading applications like Sprint and Kurzweil which some of them already use. For the buttons then it might be a solution when tapped to just read it out loud anyway and also navigate to the page. Facebook does not really have a deep hierarchy of pages so going back to the previous page is not that difficult in this application.. Some other suggestions were to ...
Paraphenylenediamine is a potent skin sensitizer, which is uniformly present in hair dyes and henna tattoos.

A contemporary history of a critical period, Are We Ready? analyzes the impact of 9/11, the anthrax attacks that followed, and preparations for a possible smallpox attack on the nations public health infrastructure. David Rosner and Gerald Markowitz interviewed local, state, and federal officials to determine the immediate reactions of key participants in these events.
As expected, RYGB rats consumed less of each of the nutritive stimuli tested than did SHAM rats. What was more interesting, though, was how intakes changed between the surgical groups across testing periods. Indeed, during sucrose and Intralipid testing, consumption by the RYGB rats did not differ from that of the SHAM rats until the second or third test period. Our group and others have previously shown that RYGB rats display less intake of and preference for sucrose and Intralipid compared with SHAM rats within a 24- to 48-h preference test (2, 4, 10, 27), but it was unclear if these intake differences would be apparent in shorter term intake tests. Here we demonstrated that, while RYGB rats did eventually drink less sucrose and Intralipid than SHAM rats, this intake difference took at least a full 60-min test period to emerge. This behavioral pattern is suggestive of a learned process based on postingestive consequences as opposed to an immediate reaction to changes in the perceived ...

Food allergies are divided into two major categories: immediate and delayed. Immediate reactions occur quickly and in some cases can be life-threatening. These are considered fixed allergies.. Delayed reactions are considered food sensitivities and occur gradually and are not life-threatening. They do however contribute to many other conditions like irritable bowel syndrome, rheumatoid arthritis, headaches, ADD/ADHD, even skin conditions like eczema and rosacea.. Our Alletess food sensitivity tests come with a four-day meal rotation plan, elimination diet, and wellness plan to help desensitize you to reduce symptoms. ...
Her teachers describe her as a brilliant student. Srishti says that it took almost a year of hard work to develop the project and she is grateful to her parents and teachers for their help. She wants to become a research scientist.. Google Science Fair is an online science competition sponsored by Google, Lego, CERN, National Geographic and Scientific American and started in January 2011. It is open to students in the age bracket of 13 to 18 around the globe who formulate a hypothesis, perform an experiment and present their results.. "The biggest challenge in the project," said Srishti, "was to carry out the research. Its a tough competition but I am geared up for it.". The Project in her words:.

Introduction. ________________ 2.0 Abstract: From the experiment, we become understand about dynamic equilibrium and Le Chatelier?s principle. Besides, we able to observe the change of an equilibrium when the concentration of a reactant or product is altered. We also know how to predict the effect of concentration changes on chemical equilibrium. This report shows, whenever a system in equilibrium is disturbed the system will adjust itself in such a way that the effect of the change will be reduced or moderated. Changing the concentration of a chemical will shift the equilibrium to the side that would reduce that change in concentration. The chemical system will attempt to partly oppose the change affected to the original state of equilibrium. In turn, the rate of reaction, extent, and yield of products will be altered corresponding to the impact on the system. The principle is used to manipulate the outcomes of reversible reactions, often to increase the yield of reactions. 3.0 Introduction: ...

For the reaction between hydrogen and iodine suppose a mole of hydrogen and b moles of iodine are mixed in a scaled bulb at 444ºC in the boiling sulphur for some time. The equilibrium mixture is then cooled and the bulbs are opened in the solution of NaOH. Let the amount of hydrogen consumed at equilibrium be x moles which means that the amount of hydrogen left at equilibrium is a-x moles. Since 1 mole of hydrogen reacts with 1 mole of iodine o form two moles of hydrogen iodide hence the amount of iodine used is also x moles so its moles at equilibrium are b-x and the moles of hydrogen iodide at equilibrium are 2x ...
The solubility of a two-component, H 2 O+CO 2 fluid in silicate liquids was modeled by assuming mechanical, thermal, and chemical equilibrium between the fluid and liquid phases. The liquid phase was treated as a 12-component (10 major oxides+H 2 O+CO 2 ) mixture, and its thermodynamic properties were calculated on the basis of a regular and non-isometric mixing equation for the excess Gibbs free energy. The mole fractions of the exsolved and dissolved water and carbon dioxide were calculated on the basis of two chemical equilibrium and two mass-balance equations expressing the conservation of the exsolved and total mass of volatiles. The model was then calibrated by processing nearly 1000 experimental H 2 O and CO 2 solubility determinations from the literature in natural and synthetic silicate liquids covering a wide range of pressure-temperature-composition conditions. The results show that the present model predicts with reasonable accuracy the solubility of water and carbon dioxide in ...

We develop a model of chemical equilibrium mixtures containing the elements H, C, F. We show that the shock response of a wide variety of molecular and polymeric fluorocarbons can be modeled as a chemical equilibrium mixture of a small number of dissociation product molecules. HF is known to strongly associate in the supercritical fluid phase. We predict that such an association also occurs under shock conditions.

For example Amanda and I began discussing how to insure our child will eat (and hopefully enjoy) a wide range of foods after a friends three-year old daughter declared she would no longer eat vegetables. Our immediate reaction was that though this seems to be a problem for every other parent in the world, for many reasons, we do not foresee this being a major battle we will need to wage. First, as a member of a vegetarian family our kid is going to be pretty hungry if it doesnt eat vegetables. I realize I could be underestimating a childs willingness to partake in a hunger strike if it ends in a diet of macaroni & cheese and vegan cupcakes (trust me, vegan cupcakes are the best). Second, we eat a wide range of foods prepared many different ways. We hope this variety will help our child discover what foods it likes and tolerate those it likes less. Third, we are good cooks. Fourth, we cook primarily from scratch. Prepackaged foods and fast food are full of sodium and fats that provide instant ...
As a part of the millennial generation, Ive been immersed in a world that has been dominated by wireless communication. For the past eighteen years, Ive grown accustomed to being surrounded by social media and thus know nothing different. Social media platforms such as Snapchat, Instagram, Facebook, and Twitter are most likely to be found on anyones phone thats under the age of twenty-five. This especially holds true on our campus. It is impossible to walk around without seeing someone glued to their phone within a few feet radius. I have to admit I am also one of those people too. I can easily spend at least two hours a day on social media and at times for even a longer duration. What exactly draws us to social media though? As our world technologically progresses, so does our desire to keep up. We are also surrounded by an atmosphere where social pressure is rampant. If someone didnt have any form of social media, my immediate reaction would be that they need to get with the times. It is ...
Notice a pattern here? Food intolerance activates the immune system in the gut! This is exactly how we can test for food intolerance. Contact a Doctor that can test to see if you immune system is in over drive. Most Doctors will test for food allergy by ordering IgE (immune system antibody). IgE is activated when there is immediate reaction - like a life-threatening peanut allergy. What most Doctors fail to test for is IgG, this is a delayed immune response that is activated when the food is a threat and needs to be eliminated. Even though IgG is a delayed reaction, chronic activation of the immune response to a foreign substance (food allergy) can cause harm to your body. When your immune system is in constant state of activation, your body is stressed out, unable to derive nutrients from foods, and is having a hard time replenishing lost energy stores ...
Affective stimuli can influence immediate reactions as well as spontaneous behaviors. Much evidence for such influence comes from studies of facial expressions. However, it is unclear whether these effects hold for other affective stimuli, and how the amount of stimulus processing changes the nature of the influence. This paper addresses these issues by comparing the influence on consumption behaviors of emotional pictures and valence-matched words presented at suboptimal and supraliminal durations. In Experiment 1, both suboptimal and supraliminal emotional facial expressions influenced consumption in an affect-congruent, assimilative way. In Experiment 2, pictures of both high- and low-frequency emotional objects congruently influenced consumption. In comparison, words tended to produce incongruent effects. We discuss these findings in light of privileged access theories, which hold that pictures better convey affective meaning than words, and embodiment theories, which hold that pictures better
Anxiety is very common. Some types of anxiety are healthy, but if it starts to overwhelm your everyday life, you could be living with an anxiety disorder. Anxiety includes feelings of worry, nervousness and panic. Its different from fear, which is an immediate reaction to a perceived threat. Its common for everyone to experience anxiety sometimes. Some types of anxiety are healthy and can help you get things done. When anxiety starts to overwhelm your daily life, it could mean youre living with an anxiety disorder.
Latex allergy can lead to a number of symptoms. The most common reaction is that it occurs in the skin. And this can either be an immediate reaction in the case of hives, or a delayed reaction where a rash appears several weeks after exposure to latex.
I recently tried going 2 weeks without gluten because I was tired of always being bloated and having stomach aches (and other assorted stomach related symptoms-aka less than perfect stools). After 2 weeks of making sure nothing I ate had any gluten in it, I had a large piece of fully gluten-ed bread (I know because I baked it). About an hour later, I vomited a little. But, my immediate reaction was disbelieve (and apparently to boldly wave my fist at the symptom). So, needless to say, for dinner I had two more pieces of bread and a muffin (though in total less calories than I normally consume). By that night my stomach was bloated to the point it looked like I could have been several months pregnant. I thought that was where it would end. But by midday the next day, I was vomiting a little bit here and there. And by that night, I had emptied my entire stomach with a few extra empty efforts by my stomach just to make sure. And I felt so terrible afterwards that I think I had a food aversion to ...
There had to be a reason why he was constantly stuffed up without being sick. I consulted a naturopath who suggested that a food allergy could be causing his enlarged tonsils so she recommended food allergy testing. She explained the tricky part about identifying food sensitivities is that they dont have an immediate reaction. I thought, no way he has any food allergies, hes never had a strange reaction to any foods, and I thought he was pretty regular - 5 times a day regular.. The allergy test she recommended is called an IgG test. I had no idea this was. When I thought about allergy testing, I thought about the scratch tests where they scratch you with potential allergens and look for a visible reaction.. I learned that food allergies are a reaction to food proteins and are categorized in mainly two ways; as an immunoglobulin E (IgE)-mediated (immediate) reaction or a non-IgE-mediated (delayed) reaction. I had associated food allergies with IgE reactions, which would immediately result in ...
Abstract. A clay-supported copper nitrate (Claycop) and a catalytic amount of (2,2,6,6-tetramethylpiperidin-1-yl)oxyl enable an inexpensive and mild reagent system for the nitration of a wide variety of aromatic and aliphatic olefins. High conversions and exclusive E-selectivity, together with the environmentally benign nature of the Claycop reagent, make this a green method and an attractive alternative to established methods.. ...
Balanced chemical equations can now be applied to the concept of chemical equilibrium, the state in which the reactants and products experience no net change over time. This occurs when the forward and reverse reactions occur at equal rates. The equilibrium constant is used to determine the amount of each compound that present at equilibrium. Consider a chemical reaction of the following form:. \[ aA + bB \rightleftharpoons cC + dD\]. For this equation, the equilibrium constant is defined as:. \[ K_c = \dfrac{[C]^c [D]^d}{[A]^a [B]^b} \]. The activities of the products are in the numerator, and those of the reactants are in the denominator. For Kc, the activities are defined as the molar concentrations of the reactants and products ([A], [B] etc.). The lower case letters are the stoichiometric coefficients that balance the equation.. An important aspect of this equation is that pure liquids and solids are not included. This is because their activities are defined as one, so plugging them into ...
Chapter Two LeChatlelier -- I thought that the earths climate was in a stable equilibrium -- like a chemical equilibrium. I am a chemist, and it was natural to see the world that way. In chemistry there is a concept called Le Chateliers principle which holds that a chemical system will alter itself to re-establish equilibrium. Last year, I heard a climate change denier make such an argument . (Here is a more sophisticated version.) At the time I thought the same, I thought more CO2 in the air, would mean faster growing forests and more algae in the sea. The biosphere would moderate the increase. As Time passed scientists tested one source of CO2 absorption after another, and nothing is fast enough. There are still people fertilizing the sea to increase CO2 absorption, but the best data shows the algae are eaten by other animals before they sink to the bottom of sea and leave the biosphere. Lets remember ocean fertilization though, because it is a Geoengineering Idea ...
This paper outlines the development of a dual hydrazine/nitrogen dioxide (HZ/NO2) prototype fiber optic sensor utilizing an acid-base indicator that undergoes color changes depending on which gas is present. Bromothymol blue bromocresol green mixture (1/1) in hydrogel (1/1), produces a blue-green indicator for HZ and/or NO2. The sensor was tested several times over a period of eight weeks and the response was consistent and proved the feasibility of dual HZ/NO2 leak detection. Prototype sensor construction, the hardware, and the software of the electronic interrogator circuitry are briefly explained. The paper presents a summary of sensor response when exposed to 52 ppm and 18 ppm hydrazine and 400 ppm and 200 ppm nitrogen dioxide ...

Background: The storage condition of a toothbrush can influence the growth of bacteria. Indonesia as a developing country has a low awareness of the importance of toothbrush hygiene. Thus, an efficient and economic toothbrush storage solution is needed. Objective: The aim of this study was to evaluate the effect of soaking toothbrushes in mouthwash solution on the total number of Streptococcus mutans and Fusobacterium on the toothbrush. Methods: Eighteen toothbrushes were provided to healthy individuals aged 19-23-years. For 1 month, each toothbrush was soaked in disinfectant solution (25 mL) for 20 min after brushing, with Group 1 using mouthwash and Group 2 using sterile tap water. The real-time polymerase chain reaction (PCR) method was used to evaluate the number of microorganisms on each toothbrush. The total number of DNA targets was identified using real-time PCR followed by SYBR Green reagents and 16S rRNA-gene specific primers for S. mutans and Fusobacterium. A paired sample t-test was ...
The diagnostic value of skin tests was assessed in 35 patients affected by bird breeders disease by comparing the results with those obtained in a group of 27 symptomless breeders and 10 symptomless unexposed individuals. Sterilised and diluted serum and lyophilised extracts of faeces prepared from the breeders own birds were injected intradermally. Skinprick tests using the same materials were carried out simultaneously. The intradermal test using serum showed a positive reaction in 18 out of 20 patients tested and in three out of 20 symptomless breeders (p less than 0.0005); later reactions occurred in eight of the patients and one of the symptomless breeders (p less than 0.01). A delayed reaction was seen in five of the patients and one of the symptomless breeders (p = 0.09). No positive reactions were recorded in symptomless unexposed individuals. Intradermal skin testing using extracts of faeces yielded an immediate reaction in 19 of 21 patients and in three of 11 symptomless breeders ...

There is a good reason for being MIA. For most of the year, I been consumed by a new world of diet and nutrition that took me on a journey I never knew existed.. While I thought I was becoming close to a nutrition "expert" - I had no idea the learning curve ahead of me.. Four days before Christmas, my daughter was diagnosed with an auto-immune disease, ulcerative colitis. When we first heard the diagnosis, my immediate reaction was, "OK, how do I fix her?" And the response I received was "there really is no cure - this is a life-long condition that she can treat with medication.". I am not writing this post for sympathy votes. Not even close. I am writing to share how much I have learned, in the hopes that I pass that learning on to a much broader audience.. The gut microbiome is a very complex and fascinating part of our bodies. Literally, our bodies function from this one main "control center". It effects our minds, digestive system, organs, energy levels…the list goes on. When the balance ...
There, they had set up a makeshift bar-b-cue out of what looked like a piece of an old car engine lined in aluminum foil, and were grilling hotdogs and selling them for 10 francs each. After a lifetime of American media exposure (and a germaphobic mother to boot) my immediate reaction was a mixture of disgust and outrage. Salmonella! E. Coli!! Botulism!! But when I got to the snack truck, I found that I could either spend my entire 20 francs on a "clean" hotdog from them, or I could buy one of the streetkids hotdogs and have money left to splurge out on a bag of chips and a soft drink. Knowing that my next meal wouldnt be until I was sitting down in the airplane the next day, I made my choice and headed back over to the steps of Trocadero. To this day, it was the tastiest hotdog Ive ever had.. Now before all you American food-bloggers in Paris get your Princesse Tam Tams in a bunch, let me just clarify- most (that is to say the great majority) of legitimate Paris food vendors adhere to ...

For some reactions, the equilibrium constant is very large, in which case nearly all of the reactant chemical is turned into products, such as when paper is burned. For other reactions, it is very small, which results in very little products being formed. If the equilibrium constant is close to 1, a mixture of both products and reactants is expected at equilibrium.. When chemists talk about equilibrium constants, they call reactions with large K values favorable and reactions with small K values unfavorable. It is important to note, however, these terms are not judgements about the value or usefulness of a particular chemical reaction. In fact, some very important reactions are actually "unfavorable"; one such example is the synthesis of ammonia from nitrogen and hydrogen gas (Haber process), which has a rather small equilibrium constant.. Understanding how chemical equilibriums work is important as it helps in understanding how a reaction happens. It allows chemists to calculate how much ...

Our research program is built on the premise that chemical separation is driven by physical field and chemical equilibrium. With the insights into how molecules are separated and detected in capillary columns, we wish to design novel instrument that can provide even more separation power for chemical analysis and purification. Interestingly, the newly designed instrument comes with newly created problems to be solved, and new phenomena to be explained. Our group enjoys meeting these challenges with many wonderful tools available to us, including what we have learned in physics, mathematics, computer science, and most importantly, chemistry! We have several projects currently being worked on:. Interface development for capillary electrophoresis- electrospray ionization - mass spectrometry (CE-ESI-MS) ...
