Study investigates prolonged pathological outcomes of traumatic brain injury

Researchers from the University of South Florida and colleagues at the James A. Haley Veterans' Hospital studying the long-term consequences of traumatic brain injury using rat models, have found that, overtime, TBI results in progressive brain deterioration characterized by elevated inflammation and suppressed cell regeneration.

New rat model simulates traumatic or surgical muscle tissue loss in humans

Penetrating soft tissue injuries that may be caused by bullet wounds or motor vehicle accidents, or exposure to explosive devices in military settings, can cause muscle loss resulting in functional disability and cosmetic deformity. Efforts underway to develop tissue engineering solutions to repair and replace damaged and lost muscle will benefit greatly from the availability of robust animal models to test these innovative therapeutic strategies.

Immune-promoting drugs may control recurrent disease

Nearly half of the 700,000 cancer patients who undergo surgical removal of a primary tumor each year suffer a recurrence of their disease at some point, and many of those patients will eventually die from their disease.

UAB research succeeds in testing a vaccine against leishmaniasis

A research coordinated by the UAB has succeeded in testing a vaccine against leishmaniasis. The vaccine was tested with the best animal model existing, the golden hamster, and can be produced at low costs by using insect larvae.

New technique may prevent inheritance of mitochondrial diseases in children

A joint team of scientists from The New York Stem Cell Foundation (NYSCF) Laboratory and Columbia University Medical Center (CUMC) has developed a technique that may prevent the inheritance of mitochondrial diseases in children.

Two recent experimental treatments improve visual function in mouse models of retinitis pigmentosa

Two recent experimental treatments - one involving skin-derived induced pluripotent stem (iPS) cell grafts, the other gene therapy - have been shown to produce long-term improvement in visual function in mouse models of retinitis pigmentosa (RP), according to the Columbia University Medical Center (CUMC) scientists who led the studies. At present, there is no cure for RP, the most common form of inherited blindness.

FUS RNA binding ability essential for development of Amyotrophic Lateral Sclerosis

Research led by Dr. Udai Pandey, Assistant Professor of Genetics at LSU Health Sciences Center New Orleans, has found that the ability of a protein made by a gene called FUS to bind to RNA is essential to the development of Amyotrophic Lateral Sclerosis (ALS). This discovery identifies a possible therapeutic target for the fatal neurological disease.

Umbilical cord stem cell therapy shows promise in infant BPD

Researchers have successfully used human umbilical cord stem cells to partially prevent damage and restore lung structure and function in an experimental animal model of bronchopulmonary dysplasia.

Paternal exposure to cocaine can impair gene expression and behavior in their offspring

Research from the Perelman School of Medicine at the University of Pennsylvania and Massachusetts General Hospital (MGH) reveals that sons of male rats exposed to cocaine are resistant to the rewarding effects of the drug, suggesting that cocaine-induced changes in physiology are passed down from father to son.

Researchers question animal models that measure generalized anxiety disorder

Pre-clinical trials - the stage at which medications or therapies are tested on animals like laboratory mice - is a crucial part of drug development. It's only then that scientists can assess benefits and side effects before a drug is administered to patients.

Novel antibodies can aid in early diagnosis of Sjogren's Syndrome

Patients suffering from the painful autoimmune disease, Sjogren's Syndrome, will soon be able to be properly diagnosed much earlier, thanks to the discovery of novel antibodies by researchers at the University at Buffalo and Immco Diagnostics, Inc. The breakthrough, described in a paper in the December issue of Clinical Immunology, will allow patients to be treated sooner when they are much more likely to benefit.

Arginase, IDO could hold clues to help 79 million Americans with prediabetes

Two enzymes that are elevated in prediabetes could hold clues to helping the 79 million Americans with the condition avoid serious vascular complications and maybe even identify those most at risk for full-blown diabetes, researchers say.

GM604 target regulates over 4,000 genes: Genervon

Genervon scientists have confirmed that the target of GM604 regulates over 4,000 genes. More significantly, it modifies ALS disease progression by modulating at least 30 significant ALS related genes. It does this through at least 8 pathways, potentially more, and up to 22 biological processes.

Activated astrocytes could play a harmful role in Alzheimer's disease

A research team composed of University of Kentucky researchers has published a paper which provides the first direct evidence that activated astrocytes could play a harmful role in Alzheimer's disease.

Study identifies KNDy neurons as a likely control switch of hot flushes

Hot flushes affect millions of people, and not just women. Yet, it is still unclear what causes the episodes of temperature discomfort, often accompanied by profuse sweating.

Scientists identify key molecular pathway that leads to depression

Scientists have identified the key molecular pathway leading to depression, revealing potential new targets for drug discovery, according to research led by King's College London's Institute of Psychiatry. The study, published today in Neuropsychopharmacology, reveals for the first time that the 'Hedgehog pathway' regulates how stress hormones, usually elevated during depression, reduce the number of brain cells.

Certain SSRI medications fail to achieve same selectivity for prevention of SUDEP

Scientists from Southern Illinois University today reported the results of a study evaluating the potential effect of two selective serotonin reuptake inhibitors (SSRI) antidepressant medications in reducing the risk of sudden unexpected death in epilepsy (SUDEP).

Enzalutamide shows promise in treating triple-negative and estrogen-positive breast cancer

Breast cancers are defined by their drivers - estrogen and progesterone receptors (ER and PR) and HER2 are the most common, and there are drugs targeting each. When breast cancer has an unknown driver, it also has fewer treatment options - this aggressive form of breast cancer without ER, PR or HER2, which was thought not to be driven by hormones, is known as triple negative.

Pain can be treated by targeting immune and nerve cells outside brain or spinal cord

The treatment of inflammatory pain can be improved by endogenous opioid peptides acting directly in injured tissue. Scientists at the Charité - Universitätsmedizin Berlin and the Université Paris Descartes showed that pain can be successfully treated by targeting immune and nerve cells outside the brain or spinal cord.

New laser surgical technique appears to be safe and effective in treating epilepsy

A developing new laser surgical technique for epilepsy appears to be safe and effective and reduces hospital stays to one or two days, according to two research reports presented today during the American Epilepsy Society 66th Annual Meting at the San Diego Convention Center.
