A new study reveals that a protein called apolipoprotein E (apoE) can protect cultured nerve cells from the damaging effects of oxygen molecules associated with Alzheimer's disease. The apoE protein has different levels of antioxidant activity, with E2 being the most effective.
Marine geologists find detailed marine record of late Pleistocene era fires on land, shedding light on natural burning's impact on climate and ecosystems. The study reveals charcoal from fires on land was transported to ocean sediments via winds and rivers.
Researchers have identified a second gene associated with hereditary multiple exostoses, a rare bone disorder characterized by the proliferation of benign tumors. The discovery provides insight into the disease's causes and potential tumor suppressor function.
An international research group has located a new gene, NIDDM2, linked to type 2 diabetes in Finland. The gene is found in the same region as MODY3, a rare early-onset form of diabetes.
Researchers found that identical twins with differing tic severities had higher binding to D2 dopamine receptors in the caudate nucleus. This finding suggests that environmental influences modify Tourette Syndrome expression, contrary to previous studies suggesting a fixed genetic component.
