...er of ordinary clay and a cell-friendly coating of amino acid, and placed cultured neurons on the very top. When light shines on them, the mercury-tellurium nanoparticle film layers produce electrons, which then move up into the PDDA film layers and produce an upward-moving electrical current. "As you bu...

Specially Developed Proteins Could Help Resist Ageing

...n and ageing,' he notes. Similar experiments on amino acids, nucleic acids and fats called lipids, using heavy forms of carbon, hydrogen, nitrogen and oxygen could be on the way. The idea has received a mixed reception from scientists in the field. Some point out that deuterium is toxic in moderate qu...

Discovery in Male Mice Gives Hope in Providing Clues to Find Infertility in Men

...ach parent. The mutation leads to a change in an amino acid in Dmc1 that blocks meiosis in its tracks, preventing sperm production. The mutant allele (one version of the pair of genes we inherit from each parent) is dominant; females who carry it remain fertile but carry the defect and pass the mutation ...

Chondroitin may Not Have Any Beneficial Effect on Arthritis, New Study Says

...e some disability caused by it. Glucosamine, an amino sugar, is thought to promote the formation and repair of cartilage. Chondroitin, a carbohydrate, is a cartilage component that is thought to promote water retention and elasticity and to inhibit the enzymes that break down cartilage. Both compounds a...

Peptide Found in Human Blood Inhibits 60 Strains of HIV, Study Says

...eir blood. According to Kirchhoff, by altering two amino acids, VIRIP's antiviral potency increased one hundredfold. VIRIP attacks a protein, called GP-41 and found on the surface of HIV, that the virus uses to penetrate the surface of human cells, the Chronicle reports. According to Warner Greene, direc...

...e comes in contact with arginine, one of 20 common amino acids in proteins. When one of the enzymes is present, nitrogen is removed from the chemical structure of arginine and it converts into citrulline. Laboratories have developed a test to measure for anti-cyclic citrullinated peptide antibody, or ant...
