Deep-brain stimulation may stop uncontrollable shaking in patients with Parkinson's

Deep-brain stimulation (DBS) may stop uncontrollable shaking in patients with Parkinson's disease and essential tremor by imposing its own rhythm on the brain, according to two studies published recently by University of Alabama at Birmingham researchers in the journal Movement Disorders.

Trudeau Institute study holds promise for improved prevention and treatment of bacterial infections

New research from the laboratory of Dr. Andrea Cooper at the Trudeau Institute, just published in the European Journal of Immunology, holds promise for the improved prevention and treatment of bacterial infections and the life-threatening complications of chronic inflammation that can result from them.

NYU-Poly creates ultra-sensitive biosensor to identify small single virus particles

Researchers at Polytechnic Institute of New York University (NYU-Poly) have created an ultra-sensitive biosensor capable of identifying the smallest single virus particles in solution, an advance that may revolutionize early disease detection in a point-of-care setting and shrink test result wait times from weeks to minutes.

Scientists use new method to easily investigate stress systems in babies

After waking up, the concentration of the stress hormone cortisol in saliva rises considerably; this is true not only for grown-ups but for babies as well. A research team from the Ruhr-Universit-t Bochum and from Basel has reported this finding in the journal Psychoneuroendocrinology.

Scientists decode signals that boost the burning of fat

The numbers of obese people are climbing steeply all over the world - with obvious major consequences for their health. Due to excess food intake and a lack of physical activity, but also due to genetic factors, the risk for overweight people dying from diseases like coronary heart disease, diabetes und atherosclerosis increases.

Metabolism drives the brain clock, reveals study

The rhythm of life is driven by the cycles of day and night, and most organisms carry in their cells a common, (roughly) 24-hour beat. In animals, this rhythm emerges from a tiny brain structure called the suprachiasmatic nucleus (SCN) in the hypothalamus. Take it out of the brain and keep it alive in a lab dish and this "brain clock" will keep on ticking, ramping up or gearing down production of certain proteins at specific times of the day, day after day.

Scientists identify genes that underlie growth of primitive leukemia stem cells

University of Rochester Medical Center scientists believe they are the first to identify genes that underlie the growth of primitive leukemia stem cells, and then to use the new genetic signature to identify currently available drugs that selectively target the rogue cells.

MAOA gene appears to make women happy

A new study has found a gene that appears to make women happy, but it doesn't work for men. The finding may help explain why women are often happier than men, the research team said.

Cyclin D3 protein regulates size and quantity of RBCs

The adult human circulatory system contains between 20 and 30 trillion red blood cells (RBCs), the precise size and number of which can vary from person to person. Some people may have fewer, but larger RBCs, while others may have a larger number of smaller RBCs. Although these differences in size and number may seem inconsequential, they raise an important question: Just what controls these characteristics of RBCs?

SPR microscopy examines binding kinetics of membrane proteins

Proteins adorning the surfaces of human cells perform an array of essential functions, including cell signaling, communication and the transport of vital substances into and out of cells. They are critical targets for drug delivery and many proteins are now being identified as disease biomarkers - early warning beacons announcing the pre-symptomatic presence of cancers and other diseases.

Human Vaccines & Immunotherapeutics Special Focus provides critical view on cancer vaccines

In one of the most comprehensive peer-reviewed discussions on cancer vaccines and immunotherapeutics, a Special Focus in the journal Human Vaccines & Immunotherapeutics provides a critical view on cancer vaccines and a discussion on best approaches for the future.

High doses of vitamin B3 stimulate CEBPE gene, enhance WBCs’ ability to combat staph infections

Cedars-Sinai researchers have found that a common vitamin may have the potential to provide a powerful weapon to fight certain "superbugs," antibiotic-resistant staph infections that health experts see as a threat to public health.

ABCD4 and CblF proteins responsible for hereditary vitamin B12 deficiency

Vitamin B12 is vital for cell division, the synthesis of red blood cells and the functioning of the nervous system. Unable to produce the vitamin itself, the human body has to obtain it via animal proteins. So far it has been known that on its way into the cell vitamin B12 is absorbed by little organelles, so-called lysosomes. From there, the vitamin enters the cell interior with the aid of the transport protein CblF, which was discovered by the same research team three years ago.
