Alcohol consumption disrupts breastfeeding hormones

...induced changes in oxytocin. The current research provides a physiological basis for Mennella's previous findings concerning alcohol's effect on breastfeeding. Those studies indicated that infants ingest less milk at the breast in the hours following maternal alcohol consumption, in part due to decreased mat...

Chemical Engineer Kao Explores Antibiotic Synthesis With DNA Chips

...veloped by the Redwood City-based company Maxygen, provides Kao with a second advantage--speed. After one round of generating mutants with transposons, only a handful of the many mutants generated will likely increase antibiotic yields. Shuffling creates combinations of all mutants that originally generated i...

Lipids get new comprehensive classification system

...e LIPID MAPS database. "The format of the LIPID ID provides a systematic means of assigning unique IDs to lipid molecules and allows for the addition of large numbers of new categories, classes and subclasses in the future," explains Dr. Fahy. "The first two characters (1-2) of the ID contain the database ide...

Second messenger NAADP shows fast, dose-related impact on satiety cycle

...usion, Yamasaki said, "Our data in this experiment provides the first direct evidence that cholecystokinin elicits a rapid, dose-dependent and selective increase in NAADP, and thus unequivocal evidence that NAADP is a crucial messenger employed by cholecystokinin." Yamasaki noted that NAADP has "a short hist...

Evidence of 600-million-year old fungi-algae symbiosis discovered in marine fossils

...carbon dioxide, while the other partner, a fungus, provides moisture, nutrients, and protection for the consortium. "When and where did they first learn the tricks to form this collaboration?" Xiao asked. "The earliest lichen fossils described by Professor Taylor were from non-marine deposits about 400 milli...

Research may provide new link between soft drinks and weight gain

A University of Cincinnati (UC) study provides new evidence that drinking large amounts of beverages containing fructose adds body fat, and might explain why sweetening with fructose could be even worse than using other sweeteners. Researchers allowed mice to freely consume either water, fructos...

Understanding how bacteria communicate may help scientists prevent disease

...ce it has reached a critical size. The Powe award provides seed money of $5,000 to faculty members who are in the first two years of their tenure track as an investment in promising achievements in an important area. The institution matches the award. Much like a legislative body, some bacteria need a quoru...

U of T researchers map role of Epstein-Barr virus in cancer

...an cells grown in culture. Frappier says the paper provides a structural explanation of this protein complex so scientists can see in molecular detail how the EBNA1 protein binds to USP7 and the resulting impact on cell growth. Once that level of detail is achieved, she says scientists can then design specifi...

Cancer drug slows poxvirus in mice

...sed by poxviruses to exit infected cells, and also provides new support for the concept of treating viral infections by targeting specific host cell molecules rather than the viruses themselves," says NIAID Director Anthony S. Fauci, M.D. The senior author of the paper, published online this week in the jour...

High-powered gene profiles provide clues to genes involved in common form of lung cancer

...he genetic errors that drive the disease. Our work provides a good starting point for scientists looking for others." As part of the study, investigators did microarray analyses on the two major subtypes of NSCLC, adenocarcinoma and squamous cell carcinoma, and found that their genomic profiles overlap in ev...

Critical step traced in anthrax infection

...sor of microbiology and molecular genetics at HMS, provides insight into the broader question of how proteins cross cell membranes. The findings appear in the July 29 issue of Science. An anthrax bacterium secretes three nontoxic proteins that assemble into a toxic complex on the surface of the host cell to ...

Genome study of beneficial microbe may help boost plant health

Some have doubted that marine reserves on the high seas would work because the big fish travel such great distances, but the new Science paper shows there are indeed consistent areas in which to priori...

Stem cells in bone marrow replenish mouse ovaries

...is week's issue of the journal Cell. This finding provides direct evidence to overturn a long-held dogma in reproductive biology, that female mice generate egg cells only during fetal development and thus are born with a finite stock of eggs that declines throughout life. The new report significantly extends...
