...and memory as well as reasoning, planning, problem solving and emotion.According to Mukherjee, patients with Alzheimer’s disease have beenknown to have a 30 percent to 50 percent loss of these receptors “Ifthere is a gradual loss of these receptors over time, Nifrolidine couldbe a potential marker for early ...

Scientists find missing enzyme for tuberculosis iron scavenging pathway

...coside N-acetyltransferase activity in Rv1347c. By solving the three-dimensional structure of Rv1347c, Dr. Baker and his colleagues have discovered that the enzyme most likely plays an entirely different role in M. tuberculosis. "What the structure showed, when combined with careful analysis of the sequence...

Papers of DNA Pioneer and Nobel Laureate Francis Crick Added to National Library of Medicine’s Profiles in Science Web Site

.... After 1953, Crick devoted most of his effort to solving the genetic coding problem, the problem of how genes controlled the synthesis of proteins. In 1961, he and Sydney Brenner reported evidence that the genetic code is to be read three letters at a time, evidence that made possible the full elucidation ...

Brain-mapping technique aids understanding of sleep, wakefulness

... Southwestern Medical Center scientist dreaming of solving the mysteries of sleep. By tracking which nerve cells in the mouse brain stimulate others, researchers in Japan and at UT Southwestern found that a type of neuron responsible for keeping animals awake receives inhibitory signals from neurons active ...

Biochemists report discovery of structure of major piece of telomerase; implications for cancer

...why they would be a problem for telomerase, but by solving the structure, we now understand how they disrupt the folding and stability of the RNA and why they are disease mutations." For telomerase to be active, it needs the telomerase RNA and a protein called human telomerase reverse transcriptase, which i...

Chickadees can help humans get their bearings

...resent. "Getting oriented is an important part of solving many spatial navigational problems, such as locating your car in the parking lot at the end of a long day in the office. This discovery points to the fact that our early experiences influence how we solve such problems and could mean that by varying ...

Scripps research scientists solve structure of a critical innate immune system protein

...lization of a protein is a crucial initial step in solving its structure via x-ray crystallography, the technique that Wilson and his colleagues employ. Because glycoproteins are covered with sugars, they are heterogenous due to the multiple glycoforms that make it harder, but not impossible, to form good cr...

Investigating 'brain shrinkage' in alcoholics

"The pathologist and neuroradiologist can identify the region of the brain to study, and the molecular biologist can take samples from these regions and look at the genes controlling structure and function and even identify individual pro...

Unweaving amyloid fibers to solve prion puzzles

... Rather than develop a single high-tech method for solving the amyloid structure, he instead used a combination of low resolution tools to analyze varieties of prion strains and piece together the puzzle of how amyloids form. "We now have an overall picture of how prions join together to form the amyloid's ...

Methamphetamine Abuse, HIV Infection Cause Changes in Brain Structure

... such as difficulties in learning new information, solving problems, maintaining attention and quickly processing information. Co-occurring methamphetamine abuse and HIV infection appears to result in greater impairment than each condition alone. “Methamphetamine abuse is linked with HIV, hepatitis C, and o...
