Portrait of "good" cholesterol

Researchers from the University of Cincinnati have determined the structure of cholesterol-containing high-density lipoproteins. The results obtained may explain how "good cholesterol" protects against cardiovascular diseases.

Erythrocytes of the universal group

Multilayer polymer "pouches" do not interfere with erythrocytes to carry oxygen and carbon dioxide, but make antigen molecules on their surface invisible to the immune system.

Ibuprofen against parkinsonism: details

Men and women who took ibuprofen two or more times a week were about 38% less at risk of developing Parkinson's disease than those who regularly took aspirin and other NSAIDs or acetaminophen.

Neurons from stem cells for the treatment of Alzheimer's disease

The possibility of growing "in vitro" one of the types of neurons that die first in Alzheimer's disease will allow us to study the causes of the disease, facilitate the creation of drugs, and in the future will make it possible to replace lost neurons with new ones.

Human Evolution: Big gains and small but Important Losses

Humans are distinguished from monkeys mainly not by genetic acquisitions, but by the loss of some DNA fragments. Due to this, we, in particular, got a big brain, but lost the "whiskers"-vibrissae and keratin spikes on the penis.

Gene therapy instead of booze?

Stimulation of the receptors of two neurotransmitters associated with binge drinking leads to a "significant reduction" of this, without a doubt, bad inclination. True, in rats.

Gene therapy of Alzheimer's disease and other neurodegenerative diseases?

An increase in Parkin's protein synthesis not only causes the breakdown of beta-amyloid in nerve cells, but also leads to the restoration of impaired neuron function. The authors plan clinical trials on patients with neurodegenerative diseases, including Alzheimer's, Parkinson's and Huntington's diseases.

Trap the virus

Artificial "cells" capable of attracting, capturing and inactivating viruses may become a new tool for studying the mechanisms by which viruses attack cells, and the basis for a new class of antiviral drugs.

AIDS gene therapy: an encouraging result

After the introduction of genetically modified T-lymphocytes, approximately 6% of the patients' T-cells turned out to be immune to HIV. In the future, this may lead to a slowdown in the development of AIDS in HIV carriers.

Global Ageing Knowledge Management System

The world's first global knowledge management system in the field of aging, the International Aging Research Portfolio (IARP), has started working to track projects, grants and publications in biomedicine with a focus on the physiological and psychological aspects of aging and age–dependent diseases
