Mechanized human hands: System designed to improve hand function lost to nerve damage

Mechanized human hands: System designed to improve hand function lost to nerve damage

Engineers at Oregon State University have developed and successfully demonstrated the value of a simple pulley mechanism to improve hand function after surgery. The device, tested in cadaver hands, is one of the first instruments ever created that could improve the transmission of mechanical forces and movement while implanted inside the body. After continued research, technology such as this may offer new options to people who have lost the use of their hands due to nerve trauma, and ultimately be expanded to improve function of a wide range of damaged joints in the human body Continue reading

Agonizing rabies deaths can be stopped worldwide

Agonizing rabies deaths can be stopped worldwide

The deadly rabies virus–aptly shaped like a bullet– can be eliminated among humans by stopping it point-blank among dogs, according to a team of international researchers led by the Paul G. Allen School for Global Animal Health at Washington State University. Ridding the world of rabies is cost-effective and achievable through mass dog vaccination programs, the scientists report in a paper that appears in the Sept Continue reading

Stem cell transplant does not cure SHIV/AIDS after irradiation of infected rhesus macaques

Stem cell transplant does not cure SHIV/AIDS after irradiation of infected rhesus macaques

A study published on September 25th in PLOS Pathogens reports a new primate model to test treatments that might cure HIV/AIDS and suggests answers to questions raised by the “Berlin patient,” the only human thought to have been cured so far. Being HIV-positive and having developed leukemia, the Berlin patient underwent irradiation followed by a bone-marrow transplant from a donor with a mutation that abolishes the function of the CCR5 gene.

Researchers engineer ‘Cas9′ animal models to study disease, inform drug discovery

Researchers engineer ‘Cas9′ animal models to study disease, inform drug discovery

Researchers from the Broad Institute and Massachusetts Institute of Technology have created a new mouse model to simplify application of the CRISPR-Cas9 system for in vivo genome editing experiments. The researchers successfully used the new “Cas9 mouse” model to edit multiple genes in a variety of cell types, and to model lung adenocarcinoma, one of the most lethal human cancers.

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

Brain chemical potential new hope in controlling Tourette Syndrome tics

A chemical in the brain plays a vital role in controlling the involuntary movements and vocal tics associated with Tourette Syndrome (TS), a new study has shown. Continue reading

How physical exercise protects the brain from stress-induced depression

How physical exercise protects the brain from stress-induced depression

Physical exercise has many beneficial effects on human health, including the protection from stress-induced depression. However, until now the mechanisms that mediate this protective effect have been unknown Continue reading

Coping techniques help patients with COPD improve mentally, physically

Coping techniques help patients with COPD improve mentally, physically

Coaching patients with chronic obstructive pulmonary disease to manage stress, practice relaxation and participate in light exercise can boost a patient’s quality of life and can even improve physical symptoms, researchers at Duke Medicine report. In a study published online Sept Continue reading
