Mobilizing the lymphatic system may help combat obesity-induced metabolic syndrome

The search by scientists to find ways to combat obesity continues. Recently, investigators have been exploring whether they can engage the lymphatic system to help regulate obesity-induced inflammation of fat (adipose) tissue and restore systemic metabolic fitness. In a study appearing in he American Journal of Pathology, researchers report that augmenting lymphatic vessel formation in

Discovery of blood vessel system in bones

A network of very fine blood vessels that connects bone marrow directly with the blood supply of the periosteum that was previously overlooked has now been discovered by Dr. Anika Grüneboom, a young researcher who is now working at Universitätsklinikum Erlangen. She made this groundbreaking discovery while working on her doctoral thesis at Universität Duisburg-Essen

A fully human system to cultivate skin cells for grafting

Breakthrough study to culture human skin cells called keratinocytes to produce skin grafts has been published by a team of researchers from Duke-NUS Medical School and the Singapore General Hospital (SGH). This method is the first to use a specific type of tissue-proteins known as laminins, found in the human body, to create a safer

How the grid cell system of the brain maps mental spaces

It has long been known that so-called place cells in the human hippocampus are responsible for coding one’s position in space. A related type of brain cell, called grid cells, encodes a variety of positions that are evenly distributed across space. This results in a kind of honeycomb pattern tiling the space. The cells exhibiting

Eyes turn to Vermont as it sees success with health system

A Vermont health care organization working to keep patients healthier while reducing costs is being closely watched because of its rate of success—it was within 1 percent of meeting its financial target in its first year and has now been expanded to cover about 18 percent of the state’s population, officials said. Last year, OneCare

Nation’s first cardiac ablation with mapping system recently cleared by the FDA performed at Penn Medicine

After eight years of failed treatment for persistent atrial fibrillation (AF), Janet Szilagyi, 78 of Clayton, New Jersey, became the first patient in the United States to undergo cardiac ablation—a procedure in which an electrophysiologist will scar or destroy tissue in the heart that’s allowing incorrect electrical signals to cause an abnormal heart rhythm—using an

When your immune system meddles in your love life

About a decade ago, evolutionary psychologists suggested that humans have evolved a first line of defense against disease: a behavioural immune system (BIS). This system is thought to be unconsciously activated, to varying degrees, when an individual perceives, rightly or wrongly, that there is a threat of disease. Although we cannot see microorganisms with our

Fetal immune system rejects the mother in preterm labor

Preterm labor, a common pregnancy complication, has long been a mystery to scientists. But a new study from UC San Francisco shows it may sometimes happen when the fetal immune system “wakes up” too early and begins to reject the mother, causing the uterus to start contracting. The researchers think the fetal immune system becomes
