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...

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...

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

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...
