Study: Gene therapy can boost heart muscle function

In an animal study, researchers at the University of Washington show that it is possible to use gene therapy to boost heart muscle function. The finding suggests that it might be possible to use this approach to treat patients whose hearts have been weakened by heart attacks and other heart conditions.

Johns Hopkins undergraduates develop Cooling Cure to protect newborn from brain damage

When babies are deprived of oxygen before birth, brain damage and disorders such as cerebral palsy can occur. Extended cooling can prevent brain injuries, but this treatment is not always available in developing nations where advanced medical care is scarce.

Study shows wireless, self-contained sensor records, transmits brain activity data

A compact, self-contained sensor recorded and transmitted brain activity data wirelessly for more than a year in early stage animal tests, according to a study funded by the National Institutes of Health.

University of Pittsburgh researchers receive NIH grant to develop wearable artificial lung

Each year, nearly 350,000 Americans die of some form of lung disease, with another 150,000 patients needing short- and long-term care. Unfortunately, current breathing-support technologies are cumbersome, often requiring patients to be bedridden and sedated.

Researchers develop single molecule test for detecting methylated DNA

Collaborators from Mayo-Illinois Alliance for Technology Based Healthcare have developed a new, single molecule test for detecting methylated DNA. Methylation -- the addition of a methyl group of molecules to a DNA strand -- is one of the ways gene expression is regulated.

Study shows how high shear stress could cause VWF to change shape and form blood clots

New research from Rice University, Baylor College of Medicine (BCM) and the Puget Sound Blood Center (PSBC) has revealed how stresses of flow in the small blood vessels of the heart and brain could cause a common protein to change shape and form dangerous blood clots.

Engineering chemotherapy drugs' shape increases their ability to target and inhibit cancer cells

Bioengineering researchers at University of California, Santa Barbara have found that changing the shape of chemotherapy drug nanoparticles from spherical to rod-shaped made them up to 10,000 times more effective at specifically targeting and delivering anti-cancer drugs to breast cancer cells.

Researchers use 3D printing and injectable gels to create bioengineered ears

Physicians at Weill Cornell Medical College and biomedical engineers at Cornell University have succeeded in building a facsimile of a living human ear that looks and acts like a natural ear. Researchers believe their bioengineering method will finally succeed in the long quest by scientists and physicians to provide normal looking "new" ears to thousands of children born with a congenital ear deformity.

Researchers explore cellular signals produced by the body in response to traumatic injury

When it comes to healing the terrible wounds of war, success may hinge on the first blood clot - the one that begins forming on the battlefield right after an injury. Researchers exploring the complex stream of cellular signals produced by the body in response to a traumatic injury believe the initial response - formation of a blood clot - may control subsequent healing.

Researchers create new ultra-sensitive tool for chemical, DNA and protein analysis

Utilizing optical characteristics first demonstrated by the ancient Romans, researchers at the University of Illinois at Urbana-Champaign have created a novel, ultra-sensitive tool for chemical, DNA, and protein analysis.

Study shows importance of lncRNAs for regulation of adipogeneis

Whitehead Institute researchers have identified a previously unrecognized layer of genetic regulation that is necessary for the generation of undesirable white fat cells. When this regulation is disrupted, white fat cells are unable to accumulate lipid droplets or mature from their precursors.

Overexpression of alpha-synuclein can cause Parkinson's

Researchers at the University of California, San Diego School of Medicine say overexpression of a protein called alpha-synuclein appears to disrupt vital recycling processes in neurons, starting with the terminal extensions of neurons and working its way back to the cells' center, with the potential consequence of progressive degeneration and eventual cell death.

Biomaterials as neural stem cell niches can help repair damage in the CNS

Despite recent advances in understanding the mechanisms of nerve injury, tissue-engineering solutions for repairing damage in the central nervous system (CNS) remain elusive, owing to the crucial and complex role played by the neural stem cell (NSC) niche. This zone, in which stem cells are retained after embryonic development for the production of new cells, exerts a tight control over many crucial tasks such as growth promotion and the recreation of essential biochemical and physical cues for neural cell differentiation.

Scientists use magnetic levitation to make in vitro lung tissue more realistic

In a development that could lead to faster and more effective toxicity tests for airborne chemicals, scientists from Rice University and the Rice spinoff company Nano3D Biosciences have used magnetic levitation to grow some of the most realistic lung tissue ever produced in a laboratory.

Institute of Bioengineering and Nanotechnology, IBM reveal new antimicrobial hydrogel

Researchers from IBM and the Institute of Bioengineering and Nanotechnology revealed today an antimicrobial hydrogel that can break through diseased biofilms and completely eradicate drug-resistant bacteria upon contact.

Knee cartilage repair success with new biomaterial

In a small study, researchers reported increased healthy tissue growth after surgical repair of damaged cartilage if they put a “hydrogel” scaffolding into the wound to support and nourish the healing process. The squishy hydrogel material was implanted in 15 patients during standard microfracture surgery, in which tiny holes are punched in a bone near the injured cartilage. The holes stimulate patients’ own specialized stem cells to emerge from bone marrow and grow new cartilage atop the bone.

Bladder Cancer Advocacy Network announces availability of three research awards

The Bladder Cancer Advocacy Network (BCAN) has announced the availability of three research awards of $100,000 each, over a two-year period. Applications will be accepted from January 9 to March 6, 2013.

Mussels may provide highly adhesive wound closure and more effective healing from surgery

Mussels can be a mouthwatering meal, but the chemistry that lets mussels stick to underwater surfaces may also provide a highly adhesive wound closure and more effective healing from surgery.

Minor mutations can lead to big improvements in antibiotic resistance

Rice University scientists have found that mutations of small effect can turn out to be game changers in the bacterial fight against antibiotic drugs.
