Johns Hopkins neuroscientists identify cause of brain degeneration in Huntington's disease

Working with genetically engineered mice, Johns Hopkins neuroscientists report they have identified what they believe is the cause of the vast disintegration of a part of the brain called the corpus striatum in rodents and people with Huntington's disease: loss of the ability to make the amino acid cysteine.

Findings support development of cysteine protease inhibitors as new drug target for AD

A team of scientists from the University of California, San Diego School of Medicine, the Medical University of South Carolina and San Diego-based American Life Science Pharmaceuticals, Inc., report that cathepsin B gene knockout or its reduction by an enzyme inhibitor blocks creation of key neurotoxic pGlu-Aβ peptides linked to Alzheimer's disease (AD). Moreover, the candidate inhibitor drug has been shown to be safe in humans.

New gold nanoparticle method allows for tracking studies of virus pathways in tissues

Enteroviruses are pathogenic viruses infecting humans. This group consists of polioviruses, coxsackieviruses, echoviruses and rhinoviruses. Enteroviruses are the most common causes of flu, but they also cause serious symptoms such as heart muscle infections and paralysis. Recently, enteroviruses have been linked with chronic diseases such as diabetes.

Decreasing levels of reactive oxygen species can break cycle of unhealing wounds

Chronic wounds affect an estimated 6.5 million Americans at an annual cost of about $25 billion. Further, foot blisters and other diabetic ulcers or sores account for the vast majority of foot and leg amputations in the United States today.

American scientists introduce novel gel for sealing wounds

In first-aid situations, wounds must be quickly and effectively closed to stop blood loss and prevent infection. For treatment on arrival in a hospital, the temporary seal must be reopened, which often causes additional damage to the injured tissue. In the journal Angewandte Chemie, American scientists have now introduced a novel gel for sealing wounds. The gel can later be dissolved and gently removed.

NAC amino acid may offer new treatment options for psychiatric disorders

Improved understanding of the roles of inflammation and oxidative stress in psychiatric disorders has generated new leads in the search for novel therapies. One such investigative compound currently in clinical trials is an amino acid, N-Acetyl Cysteine (NAC), which appears to reduce the core symptoms of bipolar disorder, schizophrenia, depression, autism and cravings in addictions including cocaine, cannabis abuse and cigarette smoking.

Immune marker predicts transplant success, improves selection of bone marrow donors

The risk of death following bone marrow transplantation can be reduced about 60 percent using a new technique to identify bone marrow donors who make the most potent cancer-fighting immune cells, according to research from St. Jude Children's Research Hospital. The findings appear in the September 16 online issue of the Journal of Clinical Oncology.
