Identified main genetic variants involved in response to HIV

... technologies, analysing 550,000 variations of the complete human genome in 486 patients, mostly European, preselected from 30,000 potential candidates. These variations, known as simple nucleotide polymorphisms (SNPs), are single variations affecting only one nucleotide or base of the genomic sequence. Des...

Cellular message movement captured on video

...ece all of these things together we can get a more complete understanding of how the cell functions, both in migration and signal transduction,” said Chien. “If we can understand the details of these processes, we can not only understand how normal cells function, but we can also look at diseased cells to see...

Blood test may help signal tumor's remission, return in throat cancer patients

...r the test. The majority of the patients had a complete response to therapy. Patients whose blood levels of these cytokines and growth factors dropped and remained low following treatment were more likely to continue in remission. Patients who experienced large increases in protein levels were more likely...

Caribbean frogs started with a single, ancient voyage on a raft from South America

...ork for the study required nearly three decades to complete because many of the species are restricted to remote and isolated mountain tops or other inaccessible areas. Some species included in the study now are believed to be extinct because of habitat degradation and possibly other causes such as climate c...

New collaborative research reveals chimpanzees can sustain multiple-tradition cultures

...rved a high-ranking female member of its own group complete an action sequence, the majority of the chimpanzees followed that sequence for the remainder of the testing period. Over time, the different methods chosen by each high-ranking female were passed among members of her group, thereby becoming a local t...

Breakthrough developments in rheumatoid arthritis reported

...s colleagues have been amassing a genetic database complete with siblings with rheumatoid arthritis (and some family members without it) in an attempt to single out those genes that are involved in the autoimmune process. In fact, in 2004, they identified a gene called PTPN2 that confers a two-fold risk for r...

Newly discovered antibody may be body's natural defense against Alzheimer's

...derate Alzheimer's disease, which is planned to be complete later this year. While this study may provide a signal of the effect of IVIG therapy to clinical outcomes, further investigation in larger controlled and longer-term trials will be needed to definitively demonstrate whether IVIG is useful in treating...

Massive herds of animals found to still exist in Southern Sudan

...itial planning for the trip, but Fay was unable to complete his surveys due to political obstacles. On Jan. 17, 2007, Fay, Elkan and Marjan set out to replicate the surveys of the early ’80s. Using the same methodology, the same flight lines, the same flight height, they began an aerial survey of three of t...

Exploring the dark matter of the genome

Human genetic 'deserts' are teeming with significant life

...nds to carry out the same kind of analysis for two complete human chromosomes. “I will be surprised if we do not find the same kind of variety in these structures”, he says. “Our work has shown that the human genome is far more complex than anyone could have imagined, even ten years ago. Understanding th...

Revealed -- Mosquito genes that could be controlling the spread of killer viruses

...ct with specific pathogens, we hope to gain a more complete understanding of the mechanisms by which a pathogen either survives inside the insect body, or is killed by the insect’s defences.” The international research team, led by Imperial PhD student Robert Waterhouse, focused on comparing the immunity g...

Ice Age extinction claimed highly carnivorous Alaskan wolves

... “Being able to say all of those things—having a complete picture—is really unusual,” said lead author Jennifer Leonard, a research associate with the Smithsonian Genetics Program, and currently at Uppsala University in Sweden. The researchers extracted mitochondrial DNA from the fossil wolf bones preser...

New vaccine prevents CMV infection and disease in mice

...ibody response. Neither approach alone would give complete protection. “In mice, the vaccine not only fought the disease, but prevented the infection from being established in the first place,” Morello said. Researchers at UCSD hope to begin pre-clinical work on development of a human vaccine. If su...

Gene expression patterns predict rapid decline in idiopathic pulmonary fibrosis patients

Based on observations in the clinic that some IPF patients display a more rapidly progressing disease course, researchers at the Simmons Center for Interstitial Lung Disease at the University of...

Thymus transplants gives hope to babies with fatal immune disease

..."We want people to know that when the diagnosis of complete DiGeorge anomaly is made, it is no longer a death sentence," said pediatric immunologist Louise Markert, M.D., Ph.D., who developed the procedure. "There is a treatment available -- thymus transplantation -- that has led to survival of most of the in...

Genome of yellow fever/dengue fever mosquito sequenced

The research appears in the May 18, 2007 Science Express, in the article, "Genome Sequence of Aedes aegypti, A Major Arbovirus Vector." Researchers at 24 universities...

Bones in motion: Brown scientists to create new 3-D X-ray system

...ill be rolled out in phases, Brainerd said, with a complete system available by 2010. The project builds on orthopedic imaging work at Henry Ford Hospital in Detroit and on original research in skeletal imaging at Brown, including a trailblazing technique developed by Gatesy that uses animation software to...

Gut research yields new anti-cancer approach

Saubermann, M.D., associate professor of Medicine at the Medical Center, realized they had come across a potentially new therapeutic ef...

Mine runoff continues to provide clues to microbial diversification
