Left-right wiring determined by neural communication in the embryonic worm

...e is understanding how the left and the right side become different from each other, and how they coordinate their activity so that every worm still has exactly one of each type of cell," says the paper's senior author Cori Bargmann, Torsten N. Wiesel Professor and head of the Laboratory of Neural Circuits ...

Biodegradable microspheres deliver time release vaccines, stimulate different immune response

... identify, target and kill cells that have already become infected, something antibodies can not do. The determine the cause of this effect, Wilson-Welder and her colleagues next incubated human dendritic cells in the presence of polyanhydride microspheres (without ovalbumin). Dendritic cells are respon...

Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

Leukemia drug turns mini-molecules up, cancer genes down

...cells that give rise to a form of white blood cell become stuck at an immature stage. The immature cells accumulate until they crowd out healthy white cells in the blood and bone marrow. "Our findings suggest that these three miRNAs help re-program the malignant cells to a more normal state," Garzon say...

NIDA study identifies genes that might help some people abstain from smoking

...uccess in quitting smoking and in vulnerability to become dependent on multiple substances include cadherin 13 (a molecule involved in cell adhesion, which governs how cells recognize and connect to their neighbors) and a cyclic G-dependent protein kinase gene, which plays a key role in normal brain develop...

It's never too late to get it back! Aging interrupted

...ulate the body to eliminate damaged cells that may become cancerous, and to stimulate repair in damaged cells like neurons and heart cells. Low calorie diets drive the body to replace and repair damaged cells. This process usually slows down as we age, but low calorie diets make the body re-synthesise and ...

Blood sugar's manufacture limited by building blocks' supply

...lled Krüppel-like family of transcription factors, become severely lacking in the blood sugar glucose—a primary energy source for the body and the sole source for the brain—after a period of overnight fasting. The researchers traced that deficiency back to an inability to produce new glucose in the liver, a...

Paper challenges 1491 Amazonian population theories

...servationists take to be ‘natural.' This view has become fashionable among many archaeologists and anthropologists, and is challenged in a recent paper from Dr. Mark Bush of the Florida Institute of Technology. The findings of Bush’s research may rekindle a debate has major implications for land use and po...

Gut research yields new anti-cancer approach

...sed, nearly 100 percent of these tumors eventually become resistant, said Alok A. Khorana, M.D., assistant professor of Medicine at the Medical Center. In cells with more drug efflux pumps, Taxol is not effective (e.g. pancreas, liver and colon), he said. High-dose PPARgamma inhibitors may overcome the l...

A 'traffic light' for neurons means 'go' for improving brain research

...trol of neuronal activity with light could someday become a therapy in itself. A neural traffic light To selectively take control of neurons, the researchers used a virus to insert genes for producing light-sensitive proteins into cells of interest. The gene ChR2 is derived from an algae that makes ...

Red flag for repetitive stress injuries identified for first time in humans

...ifferent kinds of chemicals) as the body begins to become injured by repetitive motions. These biomarkers warn of an underlying problem. "While not a diagnostic test, because the biomarkers could also indicate another type of injury, they do provide a red flag where before there was none," said Barr, ass...

In obesity, brain becomes 'unaware' of fat

Male-killing bacteria makes female butterflies more promiscuous

...promiscuity only rises up to the point where males become so rare that female virginity rates rise. The male-killling phenomenon in this species was first identified in 1920 by Hubert Simmonds but has not received much attention until now. This finding is significant for the scientific community because...
