Controlling protein diversity

...ase CAPERá and CAPERâ. These coactivators not only cause the gene to begin the process that results in protein production, they also determine what kind of RNA (a kind of genetic template for the protein) is made as well as what kind of protein results. "This subgroup of coactivators, when brought to the ...

PGA on a tour under the skin

...s is harmless on human skin, but it is the leading cause of hospital-acquired infections and infections of indwelling medical devices. S. epidermidis is associated with an enormous number of infections in people with prosthetic joints, replacement heart valves, and intravenous catheters, and antibiotic res...

Discovery Promises Simpler Therapy for Sickle Cell Disease

... red cells from those with severe disease symptoms cause blood vessels to constrict when oxygen levels drop, they found, a response which would further exacerbate the oxygen deficiency. Treatment of red blood cells with nitric oxide reversed that effect, they reported. "Our results suggest that abnormal b...

Stem Cell Research Shows Potential for Replacing Tissue Damaged in Heart Attacks

...led “precardiac endoderm?sends strong signals that cause adjacent cells in the embryo to become cardiac myocytes. Based on this finding, Dr. Lough reasoned that precardiac endoderm might similarly induce ES cells to become a homogeneous population of cardiac myocytes. Working with Diane Rudy-Reil, Ph.D., ...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

...te into fibrous tangles called amyloid fibrils and cause fatal wasting of brain tissue. The abnormally folded protein itself appears to act as an infectious agent, transmitting disease without a DNA or RNA genome such as in a virus. Although disease prions seem to infect normal prions by binding to them an...

Douglas Losordo and colleagues from Tufts University now document the existence of a previously unrecognized subset of huma...

Light therapy may combat fungal infections, new evidence suggests

.... neoformans invades the central nervous system to cause disease, most commonly in patients who lack a functioning immune system, such as organ transplant recipients, those with HIV/AIDS, and patients treated with steroids or cancer chemotherapy. The fungus' global importance as a health threat has therefo...

New lab technique identifies high levels of pathogens in therapy pool

...microbes included "Mycobacterium avium," which can cause "lifeguard lung" and which was present in nine ill lifeguards who worked at the facility. The technique used in the study is 1,000 times more sensitive than standard microbe-culturing techniques used at most indoor pool facilities today, the researc...

Nanoparticles offer new hope for detection and treatment

...h of an inch) wide. Small, rapidly growing tumors cause growth of new blood vessels, which feed the tumors. To get the particles to bind to tumors, the researchers equipped them with tiny "hooks" that link only to complementary "loops" found on cells in newly forming blood vessels. When the nanoparticles ...
