Studies to find better ways to preserve human eggs, ovarian tissue under way

...notes scientists already are developing methods to stimulate ovarian tissue to produce eggs outside the body, a process that could also make in vitro fertilization a lot more affordable. Others are looking for ways to ensure there are no cancer germ cells in salvaged tissue. If all goes as hoped with this s...

Salty oceans provide early warning for climate change

... results reveal that a build up of salty water can stimulate deep water circulation, while a diluting of the waters is linked to sluggish flow. “Salt plays a far more important role that we first thought,” says Professor Rainer Zahn, a palaeoclimatologist at the Autonomous University of Barcelona in Spain. ...

Researchers shed light on mechanism of action used by anti-cancer drug

...ion of the anti-cancer drug sorafenib, which could stimulate the development of novel regimens in which it is combined with other molecularly targeted agents for patients with blood cancers and solid tumors. In the new study, led by Steven Grant, M.D., Massey’s associate director for translational research a...

Runners -- Let thirst be your guide

...estigators have been researching the triggers that stimulate AVP secretion during exercise, and have found several. One is a loss of fluid from the body and blood as a result of sweating during prolonged exercise. Another is nausea, a common reaction to extreme sports, which makes the body think vomiting will ...

Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state

St. Jude study shows genes play an unexpected role in their own activation

...nderstand how this single transcription factor can stimulate many different genes, depending on which tissues are using it and which signaling molecule caused cAMP to put CREB to work,” Brindle said. “It is another clue to how CREB might activate the genes for enzymes that make glucose in the liver, while acti...

New study suggests potential for a broadly-protective HIV vaccine

...mely variable, so an effective vaccine may need to stimulate the body to produce cross-reactive antibodies that will neutralize multiple viral strains. These results demonstrate that induction of truly broad-spectrum neutralizing antibodies may be an achievable goal. This groundbreaking study titled: “Extensiv...

Smallpox outbreak: How long would it take for vaccines to protect people? Would it work?

...investigational vaccine made by Bavarian Nordic to stimulate the immune system against smallpox. "Vaccines prevent disease by giving the body a jump-start at recognizing the infecting virus or bacteria," said Sharon Frey, M.D., the principal investigator for the study at Saint Louis University. "After succe...

Early exposure to indoor fungus molecules may protect infants against future allergies

...s—like bacterial endotoxins and fungal glucans—can stimulate the body’s immune system to produce infection- and allergy-fighting substances. Because of this, Iossifova says, people should avoid overusing antibacterial sprays and soaps to clean their bodies and homes. "Certain microbes can have helpful affec...

Vaccine prevents prion disease in mice

...ot fight them off. To develop a vaccine that would stimulate the mice's immune system, researchers attached prion proteins to a genetically modified strain of Salmonella. For the study, the mice were orally vaccinated with a safe, attenuated Salmonella strain, which expressed the prion protein. Then they w...

Molecule that destroys bone also protects it, new research shows

...made by "T helper" cells of the immune system that stimulate immunity. Gaffen noted that until recently, immunologists believed there were only two major types of "T helper" cells -- TH1 and TH2 -- which were believed to be responsible for nearly all immune system activities. "This paradigm underwent a sea...

Egyptians, not Greeks were true fathers of medicine

...eletal disorders were treated with rubefacients to stimulate blood flow and poultices to warm and soothe. They used celery and saffron for rheumatism, which are currently topics of pharmaceutical research, and pomegranate was used to eradicate tapeworms, a remedy that remained in clinical use until 50 years ag...

High-dose anticlotting drug cuts heart attack, death risk in half

...nterferes with the action of platelet cells, which stimulate the formation of blood clots. Interventional cardiologists give patients a loading dose of this medication before PCI to protect against blood clotting. After the procedure, most patients take a lower daily dose (75 mg) for up to a year, depending on...

DOE JGI sets 'gold standard' for metagenomic data analysis
