Better knowledge of how the mechanism explaining alcohol addiction works

Alcohol, like any other substance that reinforces behaviour, such as another drug of abuse or even food, has a certain capacity to enhance social memory, that is, the ability to remember other individuals. If a mouse is administered alcohol immediately after being introduced to another animal of its own kind, the former will recognise the latter sooner.

Spliceosome crucial for processing non-coding RNA

The discovery in 1977 that the coding regions of a gene could appear in separate segments along the DNA won the 1993 Nobel Prize in Physiology or Medicine for Richard J. Roberts and Phillip A. Sharp. The active segments of a gene were termed exons, separated from each other within the gene by inactive introns.

Aβ and Fyn cooperate to cause Alzheimer-like changes in the brain

Reporting in two companion papers in the October 19 issue of the Journal of Neuroscience, investigators from the Gladstone Institute of Neurological Disease show in genetically engineered mouse models of the disease that the accumulation of Alzheimer-related neurotoxic amyloid-beta (Aâ) peptides can deplete key proteins in a specific memory center of the brain.

Discovery could lead to tests for the clinic or battlefield to diagnose ailments with just a few drops of blood

A way to detect fragments of broken brain cells that leak into the bloodstream may help doctors more quickly and precisely treat people with severe head injuries or brain diseases, say researchers at the University of Florida's McKnight Brain Institute.

Hormone responsible for types of high blood pressure could also cause preeclampsia

Researchers at the University of Cincinnati (UC) Academic Health Center have found evidence of a hormone they say is responsible for certain types of high blood pressure (hypertension), and could also cause preeclampsia, a potentially dangerous condition that occurs during pregnancy.

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.

Strain of avian influenza highly resistant to Tamiflu

An avian influenza virus isolated from an infected Vietnamese girl has been determined to be resistant to the drug oseltamivir, the compound better known by its trade name Tamiflu, and the drug officials hope will serve as the front line of defense for a feared influenza pandemic.

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.

Protein called CPSF73 performs a necessary step in the production of human chromosomes

The study found that a protein called CPSF73 acts like scissors to cut strands of histone messenger RNA (mRNA) in the cell nucleus. This cutting action produces the mRNA needed to create histone proteins that combine with DNA to form chromosomes.

Obesity associated with a threefold increase in SCD1 expression in obese muscle

The gene encoding an enzyme that hinders muscle from burning fat manufactures three times more enzyme in the muscle of obese people than lean people, researchers from Duke University Medical Center and Louisiana State University have found. This causes the obese muscle tissue to both store more fat and burn less fat, the researchers said.

Sleletal muscle findings highlight the importance of exercise in obese people

The findings suggest that muscle bears a metabolic memory of obesity, which may help to explain why sustained weight loss can be difficult despite cutting calories, according to the researchers. Exercise might more successfully override the aberrant metabolic program in muscle, they suggest, thereby improving the long-term prognosis of those prone to obesity.

Newly discovered hormone plays an important role in the digestion of fat, cholesterol, and fat-soluble vitamins

A newly discovered hormone plays an important role in the digestion of fat, cholesterol, and fat-soluble vitamins, such as vitamins A, E, and D, according to a new study in the October 2005 issue of Cell Metabolism.

Rates for new cases of kidney failure have stabilized

After 20 years of annual increases from 5 to 10 percent, rates for new cases of kidney failure have stabilized, according to new research from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). At the same time, dramatic racial disparities persist.

Technique for inserting genes into specific sites on the genome in liver cells

The genes are inserted into non-coding regions of the genome so there is no danger of interfering with the functioning of other genes. Once inserted, the gene remains a permanent part of the cell's genome.

Researchers reveal basis for hereditary coproporphyria

A research team led by scientists at The University of Texas Medical School at Houston has determined the structure of an enzyme that when defective causes an inherited disease that afflicts sufferers with severe abdominal pain, psychiatric symptoms, skin fragility, and light sensitivity.

Mitochondria and apoptosis research

The story of how mitochondria are recruited during times of stress to choreograph apoptosis--the cell's dance of death--is a story that fails to tell which particular set of steps the cells use most often, according to investigators at St. Jude Children's Research Hospital and the La Jolla Institute of Allergy and Immunology (San Diego, CA).

Discovery provides an understanding of the mechanisms of oocyte death and a way to identify potential clinical treatments for infertility

An immature egg's internal nutrient supply is critical to its survival, an insight that offers a new route to understanding and treating infertility due to egg death, according to Duke University Medical Center researchers.
