Gene controls whether fear is a factor

... of a gene that controls the ability to react with appropriate fear to impending danger. As a result, mice lacking the gene stathmin become daredevils of a sort, the researchers report. The basic findings may have general implications for the study of anxiety disorders and potential anti-anxiety drugs, according...

Brain activity related to processing faces is similar in people with, without autism

...particular brain regions that are critical for the appropriate generation of actions show deficits in autistic individuals. In addition, we wanted to see if these deficits were further compounded by the presence of social cues on which executive decisions had to be based," Belger added. The study compared fMRI ...

New understanding of regeneration gained by Forsyth scientists

...ter" control signal. "If we can learn how to send appropriate signals through gap junctions, we may be able to tell the system to make a complex structure as needed." said Levin. Michael Levin, PhD. is an Associate Member of the Staff in The Forsyth Institute Department of Cytokine Biology. Through experiment...

Implantable pumps extend lives of patients too sick for transplant

...ination therapy. The first challenge is selecting appropriate patients, which is crucial, since the patients most likely to survive would be those who are quite sick, but not too sick to be beyond help. This fine line in determining which patients are optimal will need to be defined by future clinical trials, h...

Polio vaccination strategies assessed as eradication nears

... polio eradication, they conclude that choosing an appropriate vaccination strategy to prevent poliovirus re-introduction is an important and unavoidable task. Founded in 1904, The Journal of Infectious Diseases is the premier publication in the Western Hemisphere for original research on the pathogenesis, diag...

Health of coral reefs detected from orbit

...nd coverage constraints. We need a system that has appropriate coverage and revisit frequency, with a sufficient amount of spectral bands and sensitivity. There is no more suitable system than MERIS." The team studied Heron Island reef at the southern end of the Great Barrier Reef, site of a University of Quee...

Novel enzyme offers new look at gene regulation

... 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 the years to come," said Zhang. ...

Discovering the first steps in transcription-coupled repair

...H (TFIIH) allowed XPG to cut the DNA strand at the appropriate place -- without removing the RNAPII. The best explanation is that TFIIH causes a conformational change, a "remodeling" of the RNAPII, which lifts the clamp module out of the way. This finding is especially significant because XPB and XPD, the other...

MUHC investigators search for the root of sexual pain in women

...smus and dyspareunia will undoubtedly lead to more appropriate and effective treatments." Patients who wish to be involved in this study, or wish to learn more about sexual pain in women should contact: ...

Phenolic compounds may explain Mediterranean diet benefits

...unction in humans, carefully controlled studies in appropriate populations, or with a large sample size, are required to definitively establish the in vivo antioxidant properties of these components in relation to cardiovascular disease outcomes. On the other hand, some data suggest that endothelial dysfunction ...

How the neuron sprouts its branches

...tal problem that neurons must solve is how to sort appropriate cargo molecules in the right amounts down different dendritic branches," said Ehlers. "After all, different dendritic branches can have different functional properties, molecular composition and electrical properties. So, when a cargo reaches a branc...

Scientists fetch useful information from dog genome publications

Although there were only a few animals in this initial gene pool, the considerable size differences among the founding individuals has made the PWD breed an excellent model for investigating the genetic basis of skeleta...

Stem cells from muscles can repair cartilage

... of a therapeutic gene and enabled the delivery of appropriate amounts of BMP-4 protein to the injury site," they state, adding that the improved repair lasted for 24 weeks following transplantation. Further studies conducted by the authors (not yet published) have produced similar results. They conclude: "These...

Study shows AIDS drugs cost-effective, care underfunded

...t enough," he said. "We must focus now on creating appropriate incentives for providers to care for HIV patients. The current pool of providers is struggling to make ends meet. As they begin to retire, where will the new wave of physicians come from to replace them?" A commentary accompanying the HIV expenditur...

New Rotavirus vaccine joins routine infant immunization schedule

...0 hospitalizations. In developing countries, where appropriate medical care may be unavailable, rotavirus kills as many as 600,000 children annually. Merck conducted clinical trials of RotaTeq in more than 70,000 infants in 11 countries--one of the largest clinical trials to be performed by a pharmaceutical com...

Researchers get neurons and silicon talking

...ip just 1mm squared in size. The group had to find appropriate materials and refine the topology of the chip to make the connection with neurons possible. Biologically NACHIP uses special proteins found in the brain to essentially glue the neurons to the chip. These proteins act as more than a simple adhesive, ...
