First step in exploring the GnRH reproduction-related circuitry in the brain

Howard Hughes Medical Institute researchers have discovered a vast network of neurons in the brain of mice that governs reproduction and controls the effects of reproductive status on other brain functions.

Lifelong exercise decreases cellular aging in the brain

In the first study to show that lifelong exercise decreases cellular aging in the brain, scientists from the McKnight Brain Institute of the University of Florida say that moderately active rats have healthier DNA and more robust brain cells than their less active counterparts. The research was presented at the Society for Neuroscience's 35th annual meeting in Washington, D.C.

Older brains store and encode memories differently than younger brains

Researchers working with rats have found the first solid evidence that still "sharp" older brains store and encode memories differently than younger brains.

Young scientists turn to gel to ease side-effects of cancer treatment

Three young scientists in the University of York’s Department of Chemistry have developed a gel that could spare cancer patients some of the unpleasant and dangerous side-effects of radiotherapy.

Studies outline dangers of mixing stress, deprivation and tempting foods

Two studies in the October issue of Behavioral Neuroscience show that when animals are stressed, deprived and exposed to tempting food, they overeat, with different degrees of interaction.

Protein alpha-synuclein associated with causing neurodegenerative conditions may actually protects against neurodegeneration

Researchers at UT Southwestern Medical Center have discovered that a protein associated with causing neurodegenerative conditions may, when appearing in normal amounts, actually protects against neurodegeneration.

Tryptophan metabolites play an important role in the immune system

Tryptophan is the source of Thanksgiving legend and grist for a "Seinfeld" episode, but it's not the chemical that you'd expect to find in Lawrence Steinman's lab.

Exercise is good for multiple sclerosis, but it must be done correctly

Aerobic exercise is thought to help persons with multiple sclerosis fight fatigue, the most common symptom of the disease. Yet MS also appears to cause the body to heat up more quickly, compromising the ability to exercise.

Largest study to date on risk factors associated with primary biliary cirrhosis

A case-control study of more than 2000 people has identified a number of factors that may induce primary biliary cirrhosis (PBC) in genetically susceptible individuals. These include a history of urinary tract infections, hormone replacement therapy, tobacco use, and nail polish use.

Women who smoke are more concerned about their habit and their ability to quit than men

In a new study presented at CHEST 2005, the 71st annual international scientific assembly of the American College of Chest Physicians (ACCP), the majority of smokers mistakenly believed nicotine causes cancer, leading many to smoke "light" cigarettes because they believed them to be less harmful.

Antisense molecules may hold promise in treating brain chemical problems such as Alzheimer's

Saint Louis University research shows a new class of drugs may hold promise in treating brain chemical problems such as Alzheimer's disease, says the principal investigator of research published in an early on-line version of Peptides.

Possible new directions for treatments for addiction to cocaine

Cocaine causes specific alterations in the brain's circuitry at a genetic level, including short-term changes that result in a high from the cocaine, as well as long-term changes seen in addiction, researchers from UT Southwestern Medical Center have found.

When it comes to keeping clean, old fashioned soap and water may be best

Over the last decade the popularity of soaps and cleaning products claiming to have anti-bacterial properties has mushroomed as consumers are persuaded, by clever marketing, that they offer a defense against household illnesses.

Study of the molecular mechanism involved in the human implantation process

In spite of advances in assisted reproductive technologies, more than 6.1 million women in the United States - roughly 20 percent of all women of reproductive age - suffer from infertility.

E-cadherin, that cellular touch so important in cancer

E-cadherin is a molecule involved in adhesion between epithelial cells that also seems to have a protective role in cancer, since its loss is associated with tumour progression and metastases formation in a series of different cancers.

Discovery of agent that can suppress cancer development

In a case of basic science detective work, researchers at The University of Texas M. D. Anderson Cancer Center have solved the puzzle of the "inconsistent biomarker" and, in the process, may have discovered an agent that can suppress cancer development.

PCBs found widely in the environment and absorbed in the diet - may damage sperm

Research by an European Union-supported international team of scientists has shown that polychlorinated biphenyls (PCBs) - synthetic organic chemicals found widely in the environment and absorbed in the diet - may damage sperm.

Quest to develop synthetic versions of rare natural substances to cure tobacco-related diseases

Within a laboratory on the Florida State University campus, a chemist leads a team of researchers in a quest to develop synthetic versions of rare natural substances. If all goes well, the team’s efforts could pay off in the form of the next generation of cancer-fighting drugs.
