RSS

Tryptophan is one of the 20 standard amino acids, as well as an essential amino acid in the human diet.

Lugdunin in the human nose has strong antimicrobial properties against S. aureus

Antibiotic-resistant bacteria are an increasing health threat, making new antibiotics essential. German researchers have recently had a breakthrough: they discovered lugdunin in the human nose--a new kind of cyclic peptide that comes from the bacterium Staphylococcus lugdunensis and has strong antimicrobial properties against Staphylococcus aureus, among others.

Researchers discover biochemical agent responsible for blood pressure drop in sepsis

A study conducted by an international group of researchers has overturned the understanding of life-threatening inflammatory diseases such as sepsis, pointing to a biochemical agent that may be involved in the rapid decline in blood pressure that occurs in the advanced stage of sepsis and usually causes the patient's death. This discovery could pave the way for novel therapeutic approaches.

Hormonal plants? Uncovering the melatonin biosynthesis pathway using a novel LC-MS technique

Researchers have devised a sensitive and accurate analytical LC-MS technique for the seven metabolites in the melatonin biosynthesis pathway of rice shoots.

Researchers develop new molecule that binds to the cerebrovascular system

Brazilian and US researchers have developed a molecule called FRW that, in tests with mice, proved capable of binding to blood vessels in the brain but not in other organs when injected into the bloodstream.

Protein supplements containing BCAA may have ‘detrimental effects’ on health and lifespan

New research suggests that BCAAs in the form of pre-mixed protein powders, shakes and supplements may do more harm to health than good.

Brazilian researchers reveal bactericidal action mechanism of violacein

In an article published in the journal ACS Infectious Diseases, Brazilian researchers describe the bactericidal action mechanism of violacein, a violet pigment produced by environmental bacteria, especially Chromobacterium violaceum.

Cancer cells grown in tumor-mimicking environment can help predict the effect of experimental drugs

Before being tested in animals or humans, most cancer drugs are evaluated in tumor cells grown in a lab dish.

Exercise-induced muscle changes could help boost mood in older adults, study suggests

New research suggests that exercise-induced muscle changes could help boost mood in older adults. The study is published ahead of print in the American Journal of Physiology--Cell Physiology.

Researchers develop artificial enzymatic pathway for synthesizing isoprenoids in E. coli

Researchers from North Carolina State University have developed an artificial enzymatic pathway for synthesizing isoprenoids, or terpenes, in E. coli.

New drug could significantly slow progression of ALS, shows research

A new drug could significantly slow the progression of ALS, also known as Lou Gehrig's disease, according to new research by University of Alberta biologists. Current treatments slow progression of the degenerative disease by only a few months, and these findings could revolutionize the treatment of patients suffering from ALS, extending and improving quality of life.

Brazilian professors propose guidelines for therapeutic use of melatonin

Sixty years after melatonin was isolated and with more than 23,000 published studies showing the many functions of this hormone secreted by the pineal gland, guidelines should be discussed and established for its therapeutic use.

Study uncovers link between gut bacteria and 'hedonic eating'

A study of 63 healthy people showed that those with elevated microbiome levels of the metabolite indole -; produced when gut bacteria break down the amino acid tryptophan -; had stronger function and connectivity in specific areas of the brain's reward network.

New approach could provide objective and easy-to-obtain measure of dietary adherence

An analysis of small molecules called "metabolites" in a blood sample may be used to determine whether a person is following a prescribed diet, scientists at Johns Hopkins Bloomberg School of Public Health have shown.

New studies on fat cell filling, history of biochemistry, and ketogenic diet

There's more than one type of fat cell. Besides the white fat that stores triglycerides in lipid droplets in preparation for lean times later, mammals also have heat-generating brown fat, which acts more like a radiator than a storage closet.

Key metabolites shed by gut bacteria can help protect from inflammation, study finds

Researchers at Tufts University have elucidated a mechanism by which the "good" bacteria that reside in our gastrointestinal tract can help protect us from inflammation, and how their disruption (dysbiosis) can increase the susceptibility of the liver to more harmful forms of disease.
