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

...productive system in common with the human's. The onset of puberty becomes official when gonadotropin-releasing hormone (GnRH) is secreted and sets off a chain reaction of chemical messages. Inside the hypothalamus, nerve cells release GnRH in a 'round-the-clock,' pulsatile fashion. With each secretion, t...

Martin died in 1993 just as tests of his ideas were getting underway, but scientists have embarked on a series of experiments in three major areas of the world's oceans. "The three areas are the Southern Ocean around Antarctica, the equ...

Learning to fight an adversary that won't stay down

... drugs so as to avoid overuse and the accompanying onset of resistance. "There are a relatively small number of antibiotics that have come out that are new, and some of them are very potent and act against most resistant strains," he says. "But the clinicians rightly try to keep these things in reserve fo...

Gene Therapy For Parkinson's Disease Moves Forward In Animals

...es one strategy to halt Parkinson's disease at its onset and another strategy to treat the devastating side effects that occur when treating the disease in its later stages. By inserting corrective genes into the brain, scientists studying small monkeys called marmosets prevented brain damage by producing...

Discovery Could Lead To Novel Approaches In HIV Treatment

...und that,already in the first months following the onset of infection, thymicfunction is decreased. Such a decrease results in a loweredT-lymphocyte production by the thymus.These findings pave the way to the development of novel immunotherapiesof HIV-infected individuals. Such immunotherapies could be als...

Research Using Mouse Models Reveals A Novel Key Player In The Initiation Of Colon Cancer

...is revealed that the Foxl1 deficiency affected the onset of tumor formation, accelerating them to arise in 1/3rd of the normal time. The authors examined the integrity of the APC gene in these tumor cells and found that more than ninety per cent of the tumors had lost the normal copy of the APC gene and no...
