Improving bladder function among people with spinal cord injuries

Improving bladder function among people with spinal cord injuries

People who have suffered spinal cord injuries are often susceptible to bladder infections, and those infections can cause kidney damage and even death. New UCLA research may go a long way toward solving the problem. A team of scientists studied 10 paralyzed rats that were trained daily for six weeks with epidural stimulation of the spinal cord and five rats that were untrained and did not receive the stimulation.

Sugared soda consumption, cell aging associated in new study

Sugared soda consumption, cell aging associated in new study

Sugar-sweetened soda consumption might promote disease independently from its role in obesity, according to UC San Francisco researchers who found in a new study that drinking sugary drinks was associated with cell aging. The study revealed that telomeres — the protective units of DNA that cap the ends of chromosomes in cells — were shorter in the white blood cells of survey participants who reported drinking more soda.

Conspicuous tRNA lookalikes riddle the human genome

Conspicuous tRNA lookalikes riddle the human genome

Transfer RNAs (tRNAs) are ancient workhorse molecules and part of the cellular process that creates the proteins, critical building blocks of life that keep a cell running smoothly. A new discovery suggests that the number of human genomic loci that might be coding for tRNAs is nearly double what is currently known. Most of the newly identified loci resemble the sequences of mitochondrial tRNAs suggesting unexpected new links between the human nuclear and mitochondrial genomes, links that are not currently understood Continue reading

Dynamic motion of HIV as it readies an attack: Seen in real time, for the first time

Dynamic motion of HIV as it readies an attack: Seen in real time, for the first time

Researchers at Weill Cornell Medical College have developed technologies that allow investigators, for the first time, to watch what they call the “dance” of HIV proteins on the virus’ surface, which may contribute to how it infects human immune cells. Their discovery is described in the Oct. 8 issue of Science , and is also a part of a study published the same day in Nature Continue reading

Too many stroke patients miss window to regain crucial functions

Too many stroke patients miss window to regain crucial functions

Too many stroke patients in Canada are not getting the rehabilitation they need to return to a healthy, active life, according to a new study which will be presented at the Canadian Stroke Congress in Vancouver. Continue reading

New pathway linking the brain to high blood pressure identified

New pathway linking the brain to high blood pressure identified

New research by scientists at the University of Maryland School of Medicine (UM SOM) and the Ottawa Heart Institute has uncovered a new pathway by which the brain uses an unusual steroid to control blood pressure. The study, which also suggests new approaches for treating high blood pressure and heart failure, appears today in the journal Public Library of Science (PLOS) One . “This research gives us an entirely new way of understanding how the brain and the cardiovascular system work together,” said Dr. Continue reading

Memory loss associated with Alzheimer’s reversed: Small trial succeeds using systems approach to memory disorders

Memory loss associated with Alzheimer’s reversed: Small trial succeeds using systems approach to memory disorders

Patient one had two years of progressive memory loss. She was considering quitting her job, which involved analyzing data and writing reports, she got disoriented driving, and mixed up the names of her pets. Continue reading

Scientists identify which genes are active in muscles of men, women

Scientists identify which genes are active in muscles of men, women

If you want your doctor to know what goes wrong with your muscles because of age, disease or injury, it’s a good idea to know what “normal” actually is. Continue reading

Spastic paraplegia: New light shed on cause

Spastic paraplegia: New light shed on cause

Scientists at The Scripps Research Institute (TSRI) have discovered that a gene mutation linked to hereditary spastic paraplegia, a disabling neurological disorder, interferes with the normal breakdown of triglyceride fat molecules in the brain. The TSRI researchers found large droplets of triglycerides within the neurons of mice modeling the disease. The findings, reported this week online ahead of print by the journal Proceedings of the National Academy of Sciences , point the way to potential therapies and showcase an investigative strategy that should be useful in determining the biochemical causes of other genetic illnesses.

Yoga, meditation may help train brain to help people control computers with their mind

Yoga, meditation may help train brain to help people control computers with their mind

New research by biomedical engineers at the University of Minnesota shows that people who practice yoga and meditation long term can learn to control a computer with their minds faster and better than people with little or no yoga or meditation experience. The research could have major implications for treatments of people who are paralyzed or have neurodegenerative diseases Continue reading
