Adenosine News and Research

RSS

Adenosine is a nucleoside composed of a molecule of adenine attached to a ribose sugar molecule (ribofuranose) moiety via a ß-N9-glycosidic bond.

Researchers shed light on the brain cell damage caused by Alzheimer's disease

The researchers hope that by gaining a better understanding of the disease's cellular impacts, progress can be made towards developing a treatment. The research is reported in the current edition of the Journal of Alzheimer's Disease, published by IOS publishers.

Study of Anoxia could yield better anesthetics, stroke/heart attack recovery

For a human, mere minutes without oxygen (called anoxia) resulting from cardiac arrest, cerebral stroke or being trapped under water can lead to profound tissue damage and even death. However a Western painted turtle can survive anoxia for months without apparent tissue damage. Why, and how?

RNA loops and knots guide genetic modifications

University of Connecticut Health Center scientist, Robert Reenan, has uncovered new rules of RNA recoding - a genetic editing method cells use to expand the number of proteins assembled from a single DNA code.

Lack of sleep activates the body’s defence mechanisms

A lack of sleep is considered a threat situation, which activates the body’s defence mechanisms. This is the same type of response that protects the body against viruses and bacteria as well as in stress situations.

Special imaging study shows failing hearts are energy starved

Using magnetic resonance spectroscopy (MRS) for the first time to examine energy production biochemistry in a beating human heart, Johns Hopkins researchers have found substantial energy deficits in failing hearts.

Novel enzyme in sperm is essential for spontaneous and independent movement

A study led by scientists at the University of North Carolina at Chapel Hill has found that a novel enzyme in sperm is essential for spontaneous and independent sperm movement as well as male fertility.

Smoking and coffee combined have a greater harmful effect on arteries and blood flow

Smoking and coffee often go together. But the combination appears to have a harmful effect on arteries and blood flow that is greater than would be expected from simply combining the effects of each practice.

People who drank alcohol on a regular basis appeared to have less cardiovascular disease

Many previous studies have shown a link between moderate alcohol consumption, versus abstinence or heavy consumption, and decreased mortality from cardiovascular disease.

Ultra-sensitive measurement technique shows how biomolecular motors carry out essential tasks

In the human body, hundreds of different types of biomolecular motors help carry out such essential tasks as muscle contraction, moving chromosomes during cell division, and reloading nerve cells so they can repeatedly fire.

Adenosine triphosphate is a culprit in causing the devastating damage of spinal cord injury

ATP - adenosine triphosphate, the vital energy source that keeps our body’s cells alive, runs amok at the site of a spinal cord injury, pouring into the area around the wound and killing the cells that normally allow us to move, scientists report in the cover story of the August issue of Nature Medicine.

Khat plant may create next men’s fertility wonder drug

Now, researchers at the Centre for Reproduction, Endocrinology and Diabetes at King’s College London, UK, have studied the effects of PPAs on mouse and human sperm and found the first evidence that they stimulate the final stage of sperm maturation (capacitation) when sperm develop the ability to fertilize an egg.

Magnetic resonance spectroscopy identifies women with chest pain at high risk

Women with chest pain who have a normal coronary angiogram can benefit from a test that detects abnormal metabolism in their heart muscle, according to a study reported in today’s rapid access issue of Circulation: Journal of the American Heart Association.

Research shows that treatment with nitric oxide after storage may dramatically improve the viability of transplanted livers

About 5,000 liver transplants are performed annually in the United States, and a key factor ensuring success is maintaining a healthy donor organ that can function effectively in the recipient. However, transplanted livers typically incur substantial damage when blood flow is restored to the organ after the transplant.

Combination therapy may be useful in humans with spinal cord injury

A combination therapy using transplanted cells plus two experimental drugs significantly improves function in paralyzed rats, a new study shows. The results suggest that a similar therapy may be useful in humans with spinal cord injury.

Protein that appears to play a key role in Alzheimer's disease

A protein that allows human cancer to resist multiple anticancer drugs also appears to play a key role in Alzheimer's disease, according to research conducted at Fox Chase Cancer Center. The protein, active in brain tissue, could be a target for new drugs to treat patients with Alzheimer's.

Closer to understanding the function of a protein linked to an inherited form of the movement disorder dystonia

The protein, torsinA, is defective in patients with DYT1 dystonia, an inherited condition that causes uncontrollable movements in the limbs and torso. Learning what torsinA does could be an important step toward developing a treatment for the disorder.

Small, frequent doses of caffeine best strategy for staying awake

Caffeine is the world's most widely-used stimulant yet, scientists still do not know exactly how it staves off sleep. Researchers at Brigham and Women's Hospital, Harvard Medical School and other institutions have now discovered that caffeine works by thwarting one of two interacting physiological systems that govern the human sleep-wake cycle.
