How sneaky HIV escapes cells

...ped exosomes as a quality control mechanism to get rid of clumped proteins, which are generally broken and useless. However, just as retroviruses exploit other cell processes for their own ends, it now appears they rely on exosomes to get out of infected cells and infect fresh cells. As such, drugs that...

Studies to find better ways to preserve human eggs, ovarian tissue under way

...” says Dr. Emmi. “You are concentrating on getting rid of cancer cells.” Also, if a woman has breast cancer, for example, hormones needed to induce ovulation could be problematic because many breast cancer cells have estrogen receptors. As pieces of a puzzle come together, Dr. Song notes scientists al...

Children of smokers have more than 5 times higher levels of a nicotine toxin

...ody breaks down nicotine from inhaled smoke to get rid of it. Sleeping with parents and lower temperature rooms were also associated with increased amounts of cotinine. Cotinine was measured in 100 urine samples taken from infants aged 12 weeks. Seventy one of the babies had at least one parent ...

New vaccine prevents CMV infection and disease in mice

...mune system can protect from the disease but can’t rid the body of the virus, people remain infected and can become re-infected or infect others through saliva. “Children in day care settings, for example, or adults who are sexually active, can pass along the virus,” explained Spector. “It becomes a ...

For many insects, winter survival is in the genes

... Denlinger has no plans to develop a method to get rid of heat-shock proteins in insect pests, but he says that it is important to understand how insects survive through the winter. "There may be steps we can take to disrupt the diapause process and make an insect vulnerable to low temperatures," Denl...

Thymus transplants gives hope to babies with fatal immune disease

...r which her immune system was strong enough to get rid of the virus and prevent other infections. Dave'yana then went home. "If it wasn't for Dr. Markert and her team, my baby would not be here right now," Harding said. "They really fought for my baby to get the transplant." Whether she likes it o...

Studies force new view on biology of flavonoids

...ees them as foreign compounds and is trying to get rid of them," Frei said. "But this process of gearing up to get rid of unwanted compounds is inducing so-called Phase II enzymes that also help eliminate mutagens and c...

Heart failure: Intervention possibilities from imaging programmed cell loss

...grammed cell loss—the body's normal way of getting rid of unneeded or abnormal cells—may help in early identification of those individuals who are at risk of developing heart failure, say researchers in the April Journal of Nuclear Medicine. "Our study indicates that it is feasible to noninvasively iden...

Need oxygen? Cells know how to spend and save

...w oxygen, the scientists found the cells unable to rid themselves of COX4-1. "It's remarkable that the one-celled yeast also swap COX subunits in response to hypoxia, but because they lack HIF-1, they accomplish the swap in a completely different way," says Semenza. "This suggests that adapting mitoc...

Synthetic peptide targets latent papilloma virus infections

...ncer each year. Once infected, it's difficult to rid oneself of the virus because it hides as a latent DNA in cells of the epithelial tissue, such as skin and the lining of the vagina and cervix, and spreads as these cells divide. The UC Berkeley team created a protein fragment, or peptide, that succ...

Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex

...n the form of a gritty brown powder that had to be rid of contaminants. Using techniques and tricks perfected while working on the mammoth sample, Asara purified the protein, identified as collagen, and, with the enzyme trypsin, broke it down into fragments, or peptides, 10 to 20 amino acids long. The pe...

Twin studies reveal genetic components leading to cardiac and kidney disease

...iabetes. "Normally kidneys filter the blood to rid the body of accumulated toxins. In healthy kidneys, more than a million little ‘baskets?or ‘sieves?filter out the bad chemicals without leaking ‘good?cells or proteins," said O’Connor, adding that how well these filters work appears to be a heritable...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

...After 15-20 minutes, the butanol is removed to get rid of any remaining nanoparticles that didn’t get incorporated into the beads and the beads are washed with ethanol. Then the beads are coated with a polymer that creates a hydrophilic surface on the beads. This allows the beads to be functionalized by ...

In the worst case scenario where practices don’t change, water use will also double. Agricultural practices are ...

Scientists unravel clue in cortisol production

... out the function of a protein or a gene is to get rid of it or mutate it so that it's not acting normally. Then you compare it with one that is acting normally," said Sewer. In this study, they focused on a protein known as steriodogenic factor 1 (SF-1), which is essential for making all steroid horm...
