Rockefeller research reveals vital new component of system responsible for regulating food intake

The molecular intricacies of hunger and satiety, pivotal for understanding metabolic disorders and the problem of obesity, are not yet fully understood by scientists. However, new research from The Rockefeller University reveals an important new component of the system responsible for regulating food intake: a hormone called amylin, which acts in the brain to help control consumption.

Researchers find way to inhibit enzyme responsible for Alzheimer's disease

For decades, intensive research has been conducted on drugs all over the world to treat Alzheimer's patients. Although major progress has been made in diagnostics (the disease can be detected increasingly early and accurately), the therapeutic options remain limited.

Braille maps created to help blind, visually impaired people navigate local training center

Using a high-tech 3-D printer, a Rutgers undergraduate and his professor created sophisticated braille maps to help blind and visually impaired people navigate a local training center.

Researchers develop new method to screen tumor samples for presence of human polyomaviruses

Human polyomaviruses are commonly found in the population and generally do not produce noticeable symptoms. However, one type of human polyomavirus, the Merkel cell polyomavirus, is known to cause a rare form of skin cancer called Merkel cell carcinoma, and other members of the polyomavirus family can induce non-cancer related diseases in people with compromised immune systems.

Brains have different traits that affect anatomical and cognitive factors

Everyone has a different mixture of personality traits: some are outgoing, some are tough and some are anxious. A new study suggests that brains also have different traits that affect both anatomical and cognitive factors, such as intelligence and memory.

Penn State researchers develop self-powered enzyme pumps

A new way to use the chemical reactions of certain enzymes to trigger self-powered mechanical movement has been developed by a team of researchers at Penn State University and the University of Pittsburgh. A paper describing the team's research, titled "Convective flow reversal in self-powered enzyme micropumps," is published this week in the journal Proceedings of the National Academy of Sciences.

Mice with lymphatic defects develop obesity late in life

Lymphatic vessels play multifaceted roles in the body, including the absorption of dietary lipid in the intestines as well as the movement of immune cells throughout the body. Previous work by Guillermo Oliver and colleagues showed that mice with lymphatic defects due to loss of one copy of the Prox1 gene developed obesity late in life.

Bariatric surgery reduces incidence of heart failure exacerbation in patients with morbid obesity

A new study led by Massachusetts General Hospital investigators finds that heart failure patients who underwent bariatric surgery to treat morbid obesity had a significant reduction in the incidence of heart failure exacerbation - a dangerous, sudden worsening of symptoms - in the two years following surgery.

New 3-D microscope allows researchers to look at living cancer cells in controlled microenvironment

UT Southwestern Medical Center researchers have designed and built a microscope capable of creating high-resolution, 3-D images of living cancer cells in realistic, controllable microenvironments.

Study examines sexual satisfaction of heterosexual couples in long-term relationships

A Chapman University psychologist and his interdisciplinary research team have just published a study examining the sexual satisfaction -- or dissatisfaction -- of heterosexual couples in long-term relationships, and what contributes to keeping sexual passion alive.

New imaging study shows how exercise affects the brain

People who exercise have better mental fitness, and a new imaging study from UC Davis Health System shows why. Intense exercise increases levels of two common neurotransmitters -- glutamate and gamma-aminobutyric acid, or GABA -- that are responsible for chemical messaging within the brain.

Researchers develop effective technique for studying high-arched palate using mouse model

Researchers from the laboratory of Paul Trainor, Ph.D., at the Stowers Institute of Medical Research have developed an effective and reliable technique for studying high-arched palate using a mouse model. The methodology could expand research into the genetic aspects of this craniofacial abnormality.

TTR protein causes autoimmune reaction in joints of juvenile idiopathic arthritis patients

Juvenile idiopathic arthritis, or JIA, is the most common form of childhood arthritis. It appears to be an autoimmune disease, caused by antibodies attacking certain proteins in a person's own tissue. But no "autoantigens" -- the proteins triggering an immune attack -- have been linked to JIA.

Light reflectance spectroscopy may lead to real-time tissue analysis during prostate cancer surgery

Researchers at UT Southwestern Medical Center have determined that light reflectance spectroscopy can differentiate between malignant and benign prostate tissue with 85 percent accuracy, a finding that may lead to real-time tissue analysis during prostate cancer surgery.

3D planning and CAD/CAM techniques have potential for advances in plastic and reconstructive surgery

While used mainly in craniofacial reconstruction so far, 3D planning and CAD/CAM techniques have the potential for advances in practically every area of plastic and reconstructive surgery, according to the review by Drs. Miles J. Pfaff and Derek Steinbacher of Yale University.

Uncorrected refractive error responsible for vision impairment in 101 million people worldwide

Uncorrected refractive error (URE)--nearsightedness, farsightedness, and other focusing problems correctable by prescription lenses--is responsible for moderate to severe vision impairment in 101 million people and blindness in seven million people worldwide, reports a study in the March issue of Optometry and Vision Science, official journal of the American Academy of Optometry.
