Asymptomatic HIV babies could use earlier treatment

...nts—no matter what it is—makes a big difference in preventing or delaying the progression of the disease,?said Maldonado. “Now we have to move forward to figure out if this treatment is going to be appropriate for everyone.?/p> Clinical trials are needed to determine if every infected newborn should be trea...

Tamoxifen-like drug suggests new ways to selectively block estrogen

Understanding how bacteria communicate may help scientists prevent disease

...iofilms make bacteria resistant to antibiotics, so preventing the formation of biofilms or short-circuiting bacteria's ability to become virulent by disturbing their communication network so they remain harmless, is an alternative strategy to controlling disease," he said. Kulkarni will continue his collaborat...

Antiretroviral Therapy May Prevent HIV Transmission From Breastfeeding Mothers To Infants

...ition of HIV replication in the breast milk, or by preventing infection from taking hold in the infant. The high drug concentrations raised the possibility of some risks, as well as benefits, however. Such levels may be high enough to cause adverse effects associated with the drugs, such as rash, neutropenia, ...

U of T researchers map role of Epstein-Barr virus in cancer

...ith natural cell regulation by binding to USP7 and preventing its interaction with the p53 protein. "Normally, p53 levels will increase in response to certain problems in the cell such as damaged DNA and this stops the cell from proliferating. Through binding USP7, EBNA1 keeps the p53 levels low so cells will ...

Cancer drug slows poxvirus in mice

...t that Gleevec or similar drugs might be useful in preventing adverse side effects of smallpox vaccine. The classic smallpox vaccine is made from live, weakened vaccinia virus and is not recommended for people with compromised immunity, except in emergency situations where they may have been exposed to smallpox...

Malaria mechanism revealed

... that such information might reveal strategies for preventing and treating malaria--the researchers used x-ray crystallography to determine the atomic structure of a key portion of the EBA-175 protein called the RII domain. The results revealed that two molecules of RII come together in a manner resembling a h...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

...nfected plants cells quickly commit suicide, often preventing the invader from destroying the entire plant. The new discovery appears to be a universal mechanism for defense by all plants against not only bacteria and viruses, but also parasitic fungi, insects and worms, he said. "This work is important becau...

Late peak may have prevented severe flu season from becoming worse

...n. This extra time could have been responsible for preventing many more people from becoming ill than would have been expected under the circumstances if the flu peaked at the same time it did the year before. ### To see a graph showing hospital CAP admissions for 2002-2005, go to http://www.solucient.com/tre...

Researchers discover mechanism for multiplying adult stem cells

Blink, and the brain misses it

...reness during blinks may be a neural mechanism for preventing the brain from becoming aware of the eyelid sweeping down over the pupil during a blink and the world going dark," explains Professor Frith. In summing up the study's implications, the authors suggest that when we blink, the brain may just miss it. ...

Scientists turn tobacco against cancer

...ve been used in treating metastatic disease and in preventing recurrence in certain high-risk patients. But the technology to produce large amounts of antibody is expensive, and researchers would like to find alternatives. Dr. Koprowski, Dr. Ko and their co-workers had previously shown that tobacco plant-made m...

Scientists find microRNAs regulate plant development

...then cleaves the mRNA into smaller pieces, thereby preventing translation of the protein it encodes, and thus inhibiting or "silencing" gene expression. mRNAs corresponding to several regulatory genes that mediate auxin responses contain short stretches of sequence that are complementary to microRNAs, and there...

Discoveries by UAB and Florida scientists may help transplanted organs survive longer

...at could delay rejection of transplanted organs by preventing blood-vessel deterioration. "One of the principal problems for kidney transplantation is organ availability," said Mark A. Atkinson, Ph.D., a study co-author and director of the Center for Immunology and Transplantation Research at UF. "That occurs ...

New protein vital for immune response is found in surprise location

... their findings may lead to new therapies aimed at preventing and treating viral diseases such as the flu, hepatitis, West Nile virus and SARS. The study is available online and will appear in the Sept. 9 issue of the journal Cell. Working with cultured cells, researchers found that the protein, made by a gene...

New type of rejection blocker protects kidneys after transplant

...blocks immune responses has proved as effective in preventing acute kidney transplant rejection as cyclosporine, the standard anti-rejection treatment. Patients who took the experimental drug, a co-stimulatory blocker called belatacept (LEA29Y), also had better kidney function and experienced less of the toxi...

Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses

... the body's attempt to signal for immune defenses, preventing the immune system from both stopping the spread of virus and helping the body recover from infection. Interferon is so critical for recovery from these infections that it is being tested in clinical trials to treat infection with various flaviviruse...

Secrets to antibody's success against West Nile Virus surprise scientists

...st cells. How does an antibody that's better at preventing the virus from binding to host cells actually turn out to be worse at treating infection? The key may lie in a theory known as antibody-dependent enhancement (ADE) of infection, which has been observed in test tube studies of dengue virus and may be ...
