Amino acids in nectar enhance butterfly fecundity: A long awaited link
The fascinating interactions between flowers and their pollinators have resulted in a spectacular diversity of plants. In order to entice pollinators such as bees, flies or butterflies to visit and successfully pollinate their flowers, plants have evolved intriguing mechanisms and attractants, of which nectar is best known. Thirty years ago, researchers discovered that nectars of flowers...Conserved amino acids play both structural and mechanistic roles in sandwich-like protein
The question of whether amino acids in sandwich-like proteins are there to stabilize the structure or to speed up the protein-folding process is best answered by "all of the above," according to researchers at Rice University in Houston. This discovery, reported in today's issue of the Proceedings of the National Academy of Sciences, could benefit future research on treatments for disease...New technique helps researchers determine amino-acid charge
Measurements of the ion-current through the open state of a membrane-protein's ion channel have allowed scientists at the University of Illinois at Urbana-Champaign to obtain a detailed picture of the effect of the protein microenvironment on the affinity of ionizable amino-acid residues for protons. The findings, reported in the Dec. 15 issue of Nature, are expected to be welcome news for...Use of amino acid supplement following a heart attack provides no benefit, may be harmful
Use of the amino acid supplement L-arginine following a heart attack does not improve certain cardiac functions and measurements and may be associated with an increased risk of death, according to a study in the January 4 issue of JAMA. L-arginine is a widely available dietary supplement and is publicized as having benefits for patients with hypertension, angina, heart failure and sexual d...Changes in amino acids in the 1918 influenza virus cut transmission
Modest changes in the 1918 flu virus's hemagglutinin receptor binding site—a molecular structure critical for the spread of infection—stopped viral transmission in ferrets, according to a new study conducted by researchers at Mount Sinai School of Medicine and at the Centers for Disease Control and Prevention. The finding, published in the February 1 issue of Science, could have significant clini...[14C(U)]-L-Amino Acid Mixture, 1mCi (37MBq) from PerkinElmer

RNA is often labeled with fluorescent dyes (i.e. Cy3 or Cy5) for microarray analysis. Label may be directly incorporated during cDNA synthesis, aRNA amplification or a post-aRNA reverse transcription (RT) reaction, or attached via a chemical coupling reaction performed after any enzymatic reactions...A new discovery about Acetaminophen
According to a new enzyme which is discovered, may interpret the reasons for acetaminophen acting differently from other painkillers. //Acetaminophen (paracetamol in the UK) is known to relieve pain and fever, but not inflammation. Whereas aspirin and ibuprofen tackle inflammation too and are known as non-steroidal anti-inflammatory agents (NSAIDs). These drugs are known to block two enzymes - cy...A new discovery about Acetaminophen

Although Acetaminophen can be used as a pain reliever and fever reducer after a heart attack it cannot protect the heart muscle. These were the results of a new study using sheep and rabbits concluded. // The study, using rabbits and sheep, could have implications for people who have suffered heart attacks, about a million people in the U.S. each year, said researcher Robert C. Gorman,...A Study Explores the Medical Potentials of Bucky Amino Acids
