First technology to remove prions that cause vCJD from blood launched
...operties of red cells. A filtration approach also avoids the ethical issues associated with diagnostic testing, such as alerting a blood donor that he or she has an invariably fatal disease. Regardless, there are no available diagnostic tests sensitive enough to identify asymptomatic vCJD infected people. ...Researchers develop new method for facile identification of proteins in bacterial cells
...a soup of hundreds of cell proteins. The technique avoids elaborate conventional sample preparation steps by coaxing the cells into mass production of the protein the researchers wish to analyze. "Finding a specific target in a mixture of hundreds of proteins can be likened to finding the proverbial needle ...JBC study shows that bigger isn't necessarily better for amyloid proteins
...ligomers may be a viable therapeutic approach that avoids inflammatory side effects because the oligomeric conformation is strictly pathological and non-native. The antibodies can also be used as a diagnostic tool to measure the amount of oligomers in the presence of a vast excess of native protein and fibr...Viagra shows selective effects in hypertensive pregnancy on mother, fetus
...ct of Viagra on the uteroplacental circulation and avoids some of the complications of antihypertensive therapy during pregnancy, particularly the danger of reducing uteroplacental blood flow (placental underperfusion) secondary to the reduction of systemic blood pressure." Hypertensive pregnancy develops i....... Dr. Lefebvre says that the IQ index meticulously avoids the factor that gets feathers ruffled with human IQ tests: cultural bias. The index statistically takes into account differences in the number of observations for commonly seen birds, such as crows, and rare isolated sightings. Even then, he says, th...Neural crest stem cells in skin could provide alternative to embryonic stem cell use
... cells could be used for cell therapy. The latter avoids both rejection of the implant and graft-versus-host disease. Studies in the mouse showed that neural crest stem cells from adult hair follicles are able to differentiate into neurons, nerve supporting cells, cartilage/bone cells, smooth muscle cell...Heart protein could be used to repair damage caused by heart attack
...'s senior author. "The delivery is very simple and avoids many of the problems of using stem cells." While more common in adults, heart disease is the leading noninfectious cause of death in children younger than one year. Heart disease in children is usually caused by developmental abnormalities. The prot...
