A gene's first 'kiss' sets off that affair known as puberty

...rmone (LH) and follicle-stimulating hormone (FSH), directly into the circulation. In turn, these rising levels of LH and FSH cause the testes and ovaries to produce the sex hormones testosterone and estradiol, the culprits responsible for the physical changes and emotional baggage of male and female puberty, ...

Source of molecular triggers in cutaneous T cell lymphoma identified

...Those newly available antigens are presented by LC directly to CTCL receptors, stimulating the malignant cells rapidly divide. "This finding has broad implications for the understanding, diagnosis, and treatment of CTCL, as well as potentially contributing to the investigation of other types of lymphomas," s...

W.M. Keck Foundation funds study of friendly microbes

...searchers. A second aspect of the project aims to directly identify the products of bacterial metabolism in the intestine. The goal is to characterize previously unknown chemical compounds that play important roles in regulating the properties of the microbial community and human physiology. To do so, the re...

Mouse brain cells rapidly recover after Alzheimer's plaques are cleared

In the regionof the injection, the antibodies cleared the plaques, confirmingearlier research results. Then Brendza closely monitored the swellingsfor three days."We thought that clearing the plaques would halt t...

Tiny particles could solve billion-dollar problem

...s to break down TCE is that palladium converts TCE directly into non-toxic ethane. By contrast, breaking down TCE with more common catalysts, like iron, produces intermediate chemicals, like vinyl chloride, that are more toxic than TCE. In the CBEN experiments, Wong and collaborators compared the effectivene...

Study Links Ebola Outbreaks To Animal Carcasses

...ve. In 11 cases, instances of human infection were directly linked to gorilla, chimpanzee and duiker carcasses. To prevent future outbreaks from becoming health crises, health officials and wildlife researchers must continue to work together in monitoring the region's wildlife for signs of Ebola. Shortly aft...

Bound for destruction: Ubiquitination protects against improper Notch signaling

...r of the ubiquitin ligase family of molecules that directly bindto proteins marked for degradation), as it had previously been shownthat Nedd4 plays a role in the processing of other types oftransmembrane proteins. Proteins in the cell membrane must first beinternalized through a process known as endocytosis ...

Gene therapy converts dead bone graft to new, living tissue

Researchers reveal the infectious impact of salmon farms on wild salmon

...birds. Every commercially important fish is either directly or indirectly dependent on herring." "Previous studies have been dismissed by industry, but past studies haven't looked at such large samples or the spatial aspect," says fisheries biologist Ransom Myers of the University of Dalhousie. "This study g...

Female sex hormones play a vital role in defense against sexually transmitted diseases

... are much more susceptible than men. "The results directly indicate that the hormonal conditions that provide protection against primary exposure to sexually transmitted viral infections may be very different than those that may be useful in vaccination strategies," said Kaushic. "There is of course the fli...

Spider Venom Could Yield Eco-Friendly Insecticides

... relatively easy for researchers to aspirate venom directly from its fangs. Since Australian funnel-web spiders can live for more than five years in captivity, a small group of these spiders yields plenty of toxins for King's chemical analysis. Funnel-web spider venom is a complex brew of more than 100 chemi...

Purdue proves concept of using nano-materials for drug discovery

..., contain a variety of proteins, some of which are directly responsible for cancer's ability to resist anti-tumor chemotherapy drugs. These proteins act as tiny pumps that quickly remove chemotherapy drugs from tumor cells, making the treatment less effective. Cancer cells exposed to chemotherapy drugs produc...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...rnstein notes. "Some of the genes can cause cancer directly when altered by mutations." "The work we're doing now is very fundamental," he says. "But what we learn about the interactions between chromatin, its tags, and various proteins that interact with them may one day be useful for understanding, diagnos...

ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors

Furthermore, nanoshells can be "tuned" tointeract with specific wavelengths of light by varying the thickness oftheir shells. This tunability allows for the Raman enhancements to beoptimized for speci...
