Technique to visualize changes in nerve connections when flies learn may help to understand how memories form

For the first time, researchers have used a technique called optical imaging to visualize changes in nerve connections when flies learn. These changes may be the beginning of a complex chain of events that leads to formation of lasting memories.

Protein identification gets a speed boost

But the labor intensity of the procedure is now a thing of the past for researchers in the Oregon Health & Science University School of Medicine. The Proteomics Shared Resource, an unassuming but state-of-the-art lab on the fifth floor of OHSU's Medical Research Building, can process more than three times as many protein samples in half a day, and much of it can be done by one person.

Fluorescent molecule used to examine real time chemical reactions that result in smooth-muscle contraction

Smooth muscle, found in the walls of blood vessels and in internal organs such as lungs, stomach and the bladder, contracts as the end result of a series of chemical reactions. In a new study, UT Southwestern researchers report that one set of chemical reactions resulting in the contraction of the smooth-muscle cells is augmented by a second chemical pathway that kicks in when the first pathway is limited.

Compounds that may stop replication of T-cell leukemia virus

Researchers are analyzing several compounds that may inhibit the enzyme that is essential for the reproduction of the Human T-cell Leukemia Virus Type 1 (HTLV-I), which has infected 15 to 20 million people worldwide. The virus causes the fatal adult T-cell leukemia in up to 10 percent of those infected.

Protein Hydrogels Can be Genetically Engineered to Promote

Johns Hopkins University researchers have created a new class of artificial proteins that can assemble themselves into a gel and encourage the growth of selected cell types. This biomaterial, which can be tailored to send different biological signals to cells, is expected to help scientists who are developing new ways to repair injured or diseased body parts.

New optical glucose sensor could mean help for diabetics

Researchers at the University of California, Santa Cruz, have developed a novel optical glucose sensor that could be used to provide continuous monitoring of glucose levels in diabetics and hospitalized patients. Recently published studies showed that the sensor detects glucose under physiological conditions, giving a reversible fluorescent signal that changes intensity in response to changes in the concentration of glucose.
