Some immune cells defend only one organ

Some immune cells defend only one organ

Scientists have uncovered a new way the immune system may fight cancers and viral infections. The finding could aid efforts to use immune cells to treat illness. Continue reading

Everest trek shows how some people get type II diabetes

Everest trek shows how some people get type II diabetes

Scientists have gained new insights into the molecular process of how some people get type II diabetes, which could lead to new ways of preventing people from getting the condition. The research, led by the University of Southampton and UCL, which took place on Mount Everest, assessed the mechanisms by which low oxygen levels in the body — known as hypoxia — are associated with the development of insulin resistance.

Development of new cell models that report circadian clock function

Development of new cell models that report circadian clock function

Researchers at the University of Memphis and University of Pennsylvania report the development of robust new liver and fat cell models that report circadian clock function. These models are amenable to high throughput drug screening and could be used to find promising small molecules to resynchronize or help body clocks function normally. The consequences of modern life, eating and staying up later, shift work, cell phone addiction, and travel across time zones, all disturb internal clocks. Continue reading

Laboratory-grown vaginas implanted in patients

Scientists reported today the first human recipients of laboratory-grown vaginal organs. A research team led by Anthony Atala, M.D., director of Wake Forest Baptist Medical Center’s Institute for Regenerative Medicine, describes in the Lancet long-term success in four teenage girls who received vaginal organs that were engineered with their own cells. “This pilot study is the first to demonstrate that vaginal organs can be constructed in the lab and used successfully in humans,” said Atala.

How mechanical forces affect T-cell recognition, signaling

How mechanical forces affect T-cell recognition, signaling

T-cells are the body’s sentinels, patrolling every corner of the body in search of foreign threats such as bacteria and viruses. Receptor molecules on the T-cells identify invaders by recognizing their specific antigens, helping the T-cells discriminate attackers from the body’s own cells. Continue reading

Unraveling what’s behind the sniffles, hoping for treatment

Unraveling what’s behind the sniffles, hoping for treatment

Scientists at the University of Colorado School of Medicine have shed light on one of the most common of ailments — the runny nose. Your respiratory tract is under constant attack and the nose is the first line of defense. Often, especially as the weather warms, the assault comes from allergens, which cause the body to fight off a perceived threat Continue reading

Chips with olestra cause body toxins to dip, study finds

Chips with olestra cause body toxins to dip, study finds

According to a clinical trial led by University of Cincinnati researchers, a snack food ingredient called olestra has been found to speed up the removal of toxins in the body. Results are reported in the April edition of the Journal of Nutritional Biochemistry. The trial demonstrated that olestra — a zero-calorie fat substitute found in low-calorie snack foods such as Pringles — could reduce the levels of serum polychlorinated biphenyls (PCBs) in people who had been exposed to PCBs.

Proprioceptive feedback helps rehab patients learning to operate robotic prosthetic

Proprioceptive feedback helps rehab patients learning to operate robotic prosthetic

The unconscious process by which human beings perceive the position of their body parts — known as proprioception — is a critical element of the body’s motor control system. Proprioceptive feedback plays a key role in rehabilitation following a brain injury. Continue reading

Nanoparticles cause cancer cells to self-destruct

Nanoparticles cause cancer cells to self-destruct

Using magnetically controlled nanoparticles to force tumor cells to ‘self-destruct’ sounds like science fiction, but could be a future part of cancer treatment, according to research from Lund University in Sweden.
