Study brings effective hepatitis C cure closer to reality

Scientists at The Scripps Research Institute have determined the most detailed picture yet of a crucial part of the hepatitis C virus, which the virus uses to infect liver cells. The new data reveal unexpected structural features of this protein and should greatly speed efforts to make an effective hepatitis C vaccine.

Neuroscientists discover how brain cells form "geotags" for specific memories

Using a video game in which people navigate through a virtual town delivering objects to specific locations, a team of neuroscientists from the University of Pennsylvania and Freiburg University has discovered how brain cells that encode spatial information form "geotags" for specific memories and are activated immediately before those memories are recalled.

Researchers identify gene responsible for malfunctions in fear-related memory system

A study published recently in the Journal of Neuroscience points, for the first time, to the gene trkC as a factor in susceptibility to the disease. The researchers define the specific mechanism for the formation of fear memories which will help in the development of new pharmacological and cognitive treatments.

Certain Chinese medicines can regulate neurotrophic and apoptosis-related factors

Parkinson's disease is a common neurodegenerative disease in the elderly, which is pathologically characterized by selective loss of dopaminergic neurons. Compound preparations of Chinese medicines that can tonify the kidney have been reported to significantly improve symptoms of Parkinson's disease.

Occludin and connexin 43 expression may reflect pathogenesis of brain injury

Understanding the pathogenesis of brain edema may allow for the prevention and treatment of edema in the field of neurosurgery, thus resulting in better treatments for intracranial diseases.

New injectable therapy could help treat rotator cuff injuries

For a baseball pitcher, a rotator cuff injury often means an extended stay on the disabled list for surgery and rehabilitation of the damaged tendons. But a new technology under development may stop this shoulder injury from becoming so severe that surgery is required.

Optogenetics offers a promising therapy for retinal degeneration

For a few years now optogenetics has been seen as a very promising therapy for progressive blindness, for example when it is a result of retinal degeneration.

Enzyme intervenes when cancer-fighting PTEN is bound for cell's protein-destroying machinery

A protector for PTEN, a tumor-thwarting protein often missing in cancer cells, has emerged from research led by scientists at The University of Texas MD Anderson Cancer Center published online at Nature Cell Biology this week.

Compound extracted from wine-processed Fructus corni protects hippocampal neurons from damage

Studies have shown that Fructus corni has a protective effect on hepatocytes, and has anticancer, antioxidative, anti-inflammatory and antiseptic properties. 5-hydroxymethylfurfural, a compound extracted from wine-processed Fructus corni, has a protective effect on hippocampal neurons damaged by H2O2.

Researchers identify protein in malaria that is inhibited by newly discovered anti-malarial compounds

Researchers have identified the protein in malaria-causing Plasmodium parasites that is inhibited by a newly discovered class of anti-malarial compounds known as imidazopyrazines.

Accumulation of small protein in brain’s blood vessels can drive early cognitive impairment

A team of Stony Brook University researchers led by William Van Nostrand, PhD, Professor in the Department of Neurosurgery, has discovered in a model of Alzheimer's disease that early accumulation of a small protein, known as amyloid β, in the blood vessels of the brain can drive early cognitive impairment.

NIBIB-funded researchers explore better treatment for brain aneurysms

Thirty thousand Americans suffer severe neurological damage or death from brain aneurysms each year and the existing treatments eventually fail in nearly half of patients. Currently, these "bubbles" in the blood vessel are either clamped off, which requires invasive brain surgery, or filled with platinum coils to induce clotting in the aneurysm. Both treatments, although somewhat effective, can have subsequent problems, including inflammation, incomplete healing, and the development of secondary aneurysms adjacent to the initial site. These complications result in approximately 40 percent of patients needing additional treatment to attempt to re-repair the aneurysm.

Researchers show benefits from testosterone administration in hysterectomized women

Hysterectomy and oophorectomy (the removal of ovaries) are performed to treat various diseases in women, including cancer. These procedures are accompanied not only by a decline in estrogen but also testosterone levels in the blood.

UCLA researchers identify cells involved in placenta development

Dr. Hanna Mikkola and researchers at UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have identified a specific type of cell and a related cell communication pathway that are key to the successful growth of a healthy placenta. The findings could greatly bolster our knowledge about the potential causes of complications during pregnancy.
