HIV accessory protein disables host immunity via receptor-protein intermediary

...mmatory diseases such as rheumatoid arthritis, and possibly sepsis. This research appears in the February print issue of Nature Cell Biology. Over a decade ago, Penn's David Weiner, PhD, Associate Professor of Pathology and Laboratory Medicine, and colleagues reported that Vpr corrupted the glucocorticoid re...

Serious adverse reactions to smallpox vaccine appear to be limited

...ntial first responders to a bioterrorism incident, possibly attributable to rigorous vaccine safety screening and educational programs, according to a study in the December 7 issue of JAMA. Routine childhood immunization against smallpox in the United States ceased in 1971, according to background informatio...

Biologists discover new pathway into plant cells

...ay provide a new tool to penetrate plant cells and possibly manipulate their behavior in some beneficial way ?to grow faster, resist disease or increase yields. The findings were published today in two articles in The Plant Cell, a professional journal. Also of considerable interest is that the biological m...

Asleep in the deep: Model helps assess ocean-injection strategy for combating greenhouse effect

...pth of at least 800 meters (about a half mile) and possibly as much as 3,000 meters (nearly two miles) to keep it from escaping. Eruptions from injected CO2 are a serious concern, Zhang said, "because carbon dioxide is known to have driven deadly water eruptions." In 1986, a CO2-driven eruption in Cameroon's...

New U. of Colorado at Boulder flu chip may help combat future epidemics, pandemics

...ll mutate and become transmittable between humans, possibly triggering a worldwide pandemic. "If an unusual flu subtype surfaces that has characteristics of both avian and human flu types, we could detect it rapidly using this technology," Kuchta said. Standard laboratory culturing techniques by the CDC and...

Ancient humans brought bottle gourds to the Americas from Asia

...the oldest bottle gourds ever found but also quite possibly the oldest plant DNA ever analyzed. The newest of their archaeological samples, a specimen found in Kentucky, was just 1,000 years old -- suggesting the gourds were used in the New World as containers for at least 9,000 years. ...

New study identifies key gene in development of connections between brain and spinal cord

...standing of the development of the human brain and possibly the treatment of spinal cord injuries. During fetal development, genes "instruct" nerve cells on how and where to develop. Researchers examined the plasticity of fetal cells to better understand at what developmental period cells are specialized ...

UCLA discovery will aid in treatment of patients with a deadly brain cancer

...enetic variations in the molecular signature could possibly be treated with drugs to make them more sensitive to EGFR blockers. Of the 8,000 to 10,000 glioblastoma patients diagnosed each year, about 10 to 20 percent have the combination of the mutant and PTEN proteins, Mischel said. The next step is a prosp...

How E. coli bacterium generates simplicity from complexity

... surprisingly few physiological functions. This is possibly a general principal in many, if not all, species." Palsson and his colleagues at UCSD, postdoctoral fellows Christian L. Barrett and Christopher D. Herring, and Ph.D. candidate Jennifer L. Reed, created a computer model of an E. coli cell based on t...

UK sperm donor crisis

...clear the level of commitment required as this had possibly contributed to the 30% drop-out rate over the decade of the study, particularly in the early days when fertility issues were less well known to the public. The unit is also reviewing its high cut-off rate for semen quality. However, to achieve good...

The brain is broadly wired for reproduction

...neurons influence a wide array of brain functions, possibly coordinating those functions with neuroendocrine status in order to optimize reproductive success, according to Buck. Almost all the GnRH neuron-connected areas were identical in male and female mouse brains. However, there were some telltale sex di...

Novel enzyme offers new look at gene regulation

...in the JmjC domain of a protein called "hairless," possibly due to defects in the appropriate removal of histone methyl groups. "Given the large numbers of JmjC domain-containing proteins that exist in diverse organisms ranging from yeast to human, our discovery will keep many people in the field busy for th...

Molecular research suggest shift needed in how some drugs are created

...d by the researchers at Dallas Southwestern cannot possibly exist in humans, because of bad steric interactions that preclude the formation of this particular complex," Nair said. Steric interactions refer to contacts that result when two protein molecules bind with each other. Bad interactions mean that the...

New understanding of regeneration gained by Forsyth scientists

... we can gain a greater understanding of how we can possibly direct this process in tissues that don't currently regenerate; this has clear applications towards induction of regeneration in biomedical settings." Dr. Levin and his team ultimately hope to gain an understanding of how adult stem cells are control...

New technique multiplies life span in simple organisms

...anti-aging research. Longo proposes that SIR2 and possibly its counterpart in mammals, SIRT1, may block the organism from entering an extreme survival mode characterized by the absence of reproduction, improved DNA repair and increased protection against cell damage. Organisms usually enter this mode in resp...
