New target for Parkinson's disease identified by researchers

Investigators have discovered a novel link between a protein called SV2C and Parkinson’s disease (PD). Prior work had suggested that the SV2C gene was associated with the curious ability of cigarette smoking to reduce PD risk.

Rare proteins collapse earlier

Some organisms are able to survive in hot springs, while others can only live at mild temperatures because their proteins aren’t able to withstand such extreme heat. Researchers investigated these differences and showed that often only a few key proteins determine the life and heat-induced death of a cell.

From heroin addiction to alcohol-related problems

Methadone programs and long-term therapy using other opioids evidently work. People addicted to heroin consume less heroin, cocaine and even alcohol at the beginning of the treatment. As a long-term study reveals, however, the alcohol consumption among these patients has increased considerably since the 1990s.

Study finds new link between childhood abuse and adolescent misbehavior

An important learning process is impaired in adolescents who were abused as children, a researcher has found, and this impairment contributes to misbehavior patterns later in life. A new article details the connection between impaired associative learning capacities and instances of early childhood abuse.

A better way to measure the stiffness of cancer cells

Biomedical engineers have discovered a way to detect signs of cancer on a cell-by-cell basis using two lasers and a camera. An increase in cell stiffness is an indicator of cancerous tissue, but current technology cannot gauge cells individually. In a study, researchers describe a technique for assessing an individual cell’s stiffness using patterns that appear within its internal structure.

Liver tumor growth in mice slowed with new chemo-immunotherapy treatment

Hepatocellular carcinoma is the most common form of liver cancer, but treatment options are limited and many patients are diagnosed in late stages when the disease can’t be treated. Now, researchers have developed a new treatment that combines chemotherapy and immunotherapy to significantly slow tumor growth in mice. The researchers believe that with more research, the strategy could be translated to benefit patients with the disease.
