Heart specialists reveal how pacemaker works at the biological level

Heart specialists at Johns Hopkins have figured out how a widely used pacemaker for heart failure, which makes both sides of the heart beat together to pump effectively, works at the biological level.

Fast-track genetic diagnosis for hearing loss

Over 28 million Americans are hearing impaired, and 50 percent of these cases can be traced to genetic causes. The condition can be especially challenging for children born hearing impaired because spoken language, reading, and cognitive development are tied to hearing. That makes early diagnosis essential for identifying appropriate therapy and treatment.

Uterine stem cells could help treat diabetes

Controlling diabetes may someday involve mining stem cells from the lining of the uterus, Yale School of Medicine researchers report in a new study published in the journal Molecular Therapy.

Rac1 protein triggers growth of long 'legs' that could propel melanoma cells to spread

Cancer Research UK scientists have discovered that a protein called Rac1 prompts pigment cells to sprout long 'legs' that could propel skin cancer cells, allowing them to spread, according to research published in Developmental Cell today.

Psychological stress of racial discrimination may contribute to health disparities

The consequences of psychological stress, resulting from racial discrimination, may contribute to racial health disparities in conditions such as cardiovascular disease, diabetes and other age-associated diseases.

First effective blood-stage vaccine against malaria

Scientists have identified the first effective blood-stage malaria vaccine, according to a New England Journal of Medicine study from University of Maryland School of Medicine researchers, in collaboration with the University of Bamako in Mali, West Africa, and other partners.

OXTR gene associated with optimism, self-esteem and mastery

UCLA life scientists have identified for the first time a particlular gene's link to optimism, self-esteem and "mastery," the belief that one has control over one's own life - three critical psychological resources for coping well with stress and depression.

Glucose metabolism inhibition with 2-DG induces cell death in alveolar rhabdomyosarcoma

A study made by IDIBELL researchers shows that glucose metabolism inhibition with 2-deoxyglucose (2-DG) induces cell death in a type of childhood sarcoma: alveolar rhabdomyosarcoma.

Scientist granted over $138,000 to explore Vitamin C therapy in sepsis

Sepsis kills more people than breast, colorectal, pancreatic, and prostate cancers combined. Outside of coronary care units, it is the leading cause of mortality in intensive care units. Every year 18 million people worldwide develop this potentially fatal disease. Thanks to a generous grant of $138,238.65 from the Jesse and Julie Rasch Foundation, Lawson Health Research Institute's Dr. Michael Sharpe is exploring a new sepsis therapy using Vitamin C.

Celecoxib inhibits GSK3 enzyme in lung cancer cells

Several clinical studies have shown that taking the anti-inflammatory drug celecoxib can reduce the risk of developing polyps that lead to colon cancers, at the cost of increasing the risk of heart disease. But what if this tradeoff was not necessary?

Researchers may have solved 100-year-old puzzle to safely open and close the blood-brain barrier

Cornell University researchers may have solved a 100-year puzzle: How to safely open and close the blood-brain barrier so that therapies to treat Alzheimer's disease, multiple sclerosis and cancers of the central nervous system might effectively be delivered.

Researchers combine 3-D printing technology and multiphoton polymerization to develop artificial blood vessels

Researchers have been working at growing tissue and organs in the laboratory for a long time. These days, tissue engineering enables us to build up artificial tissue, although science still hasn't been successful with larger organs. Now, researchers at Fraunhofer are applying new techniques and materials to come up with artificial blood vessels in their BioRap project that will be able to supply artificial tissue and maybe even complex organs in future.

Single UV laser pulse simultaneously zaps away biological tissue at multiple points

Researchers at Vanderbilt University have developed a new technique that uses a single UV laser pulse to zap away biological tissue at multiple points simultaneously, a method that could help scientists study the mechanical forces at work as organisms grow and change shape.

Researchers evaluate effect of Terahertz radiation on gene expression in stem cells

Terahertz technologies show promise for myriad medical, military, security, and research applications ranging from the detection of cancer to airport security systems to shipment inspection to spectroscopy. Relatively little is known, however, about the effect of THz radiation on biological systems.

'Achilles' heels' within HCV virus

Hopes for an effective vaccine and treatment against the potentially fatal hepatitis C virus (HCV) have received a major boost following the discovery of two 'Achilles' heels' within the virus.

USC scientists explore motor memory to foster better rehabilitation for stroke patients

For the first time, scientists at USC have unlocked a mechanism behind the way short- and long-term motor memory work together and compete against one another.

Neuroscientists use fMRI to identify how brain figures out scene recognition

Research conducted by Boston College neuroscientist Sean MacEvoy and colleague Russell Epstein of the University of Pennsylvania finds evidence of a new way of considering how the brain processes and recognizes a person's surroundings, according to a paper published in the latest issue of Nature Neuroscience.

BVES protein may play a role in colon cancer progression

A protein critical in heart development may also play a part in colon cancer progression. Research led by investigators from Vanderbilt-Ingram Cancer Center and the Vanderbilt Eye Institute suggests that the protein BVES (blood vessel endocardial substance) - which also is key in regulating corneal cells - may be a therapeutic target for halting colon cancer metastasis.
