Scientists evaluate two different strategies to treat Usher syndrome

After years of basic research, scientists at Johannes Gutenberg University Mainz (JGU) are increasingly able to understand the mechanisms underlying the human Usher syndrome and are coming ever closer to finding a successful treatment approach. The scientists in the Usher research group of Professor Dr. Uwe Wolfrum are evaluating two different strategies. These involve either the repair of mutated genes or the deactivation of the genetic defects using agents.

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.

Scientists demonstrate how glowing fish can help screen drugs that control metabolic disorders

A tiny, translucent zebrafish that glows green when its liver makes glucose has helped an international team of researchers identify a compound that regulates whole-body metabolism and appears to protect obese mice from signs of metabolic disorders.

Mistletoe extract plays a vital role in treating colon cancer

Mistletoe has become an important symbol of Christmas but it also has the potential to play a vital role as an alternative therapy for sufferers of colon cancer.

New antifungal drugs could be developed based on substance bacteria use to decompose mushrooms

Soft rot diseases cause a great deal of damage in agriculture, and turn fruits, vegetables, and mushrooms to mush. By using imaging mass spectrometry together with genetic and bioinformatic techniques (genome mining), German researchers have now discovered the substance the bacteria use to decompose mushrooms.

Intramyocardial injection of organ-derived stem cells after AMI improves left ventricle function

A study published in the current issue of Cell Transplantation, now freely available on-line, has found that when mesenchymal cells derived from skeletal muscle (SM-MSCs) or adipose tissue (ADSCs) were injected into the heart muscle (myocardium) of separate groups of laboratory rats that had suffered a myocardial infarction, rats in both groups experienced significantly improved left ventricle function and smaller infarct size after cell therapy.

Carnosic acid promotes eye health

Herbs widely used throughout history in Asian and early European cultures have received renewed attention by Western medicine in recent years. Scientists are now isolating the active compounds in many medicinal herbs and documenting their antioxidant and anti-inflammatory activities. In a study published in the journal Investigative Ophthalmology & Visual Science, Stuart A. Lipton, M.D., Ph.D. and colleagues at Sanford-Burnham Medical Research Institute (Sanford-Burnham) report that carnosic acid, a component of the herb rosemary, promotes eye health.

Novartis receives FDA approval for Flucelvax to prevent seasonal influenza

The U.S. Food and Drug Administration announced today the approval of Flucelvax, the first seasonal influenza vaccine licensed in the United States produced using cultured animal cells, instead of fertilized chicken eggs. Flucelvax is approved to prevent seasonal influenza in people ages 18 years and older.

Induced-pluripotent stem cells not as genetically unstable as previously thought

Stanford University School of Medicine scientists have demonstrated, in a study conducted jointly with researchers at Yale University, that induced-pluripotent stem cells - the embryonic-stem-cell lookalikes whose discovery a few years ago won this year's Nobel Prize in medicine - are not as genetically unstable as was thought.

Study shows how Parkinson's spreads and leads to nerve cell death

Understanding how any disease progresses is one of the first and most important steps towards finding treatments to stop it. This has been the case for such brain-degenerating conditions as Alzheimer's disease. Now, after several years of incremental study, researchers at the Perelman School of Medicine, University of Pennsylvania have been able to piece together important steps in how Parkinson's disease (PD) spreads from cell to cell and leads to nerve cell death.

CLR01 effectively inhibits synaptotoxicity in mice with Alzheimer's

Last March, researchers at UCLA reported the development of a molecular compound called CLR01 that prevented toxic proteins associated with Parkinson's disease from binding together and killing the brain's neurons.

CD22 protein could prove to be important new target for anti-cancer therapy

A team of UC Davis investigators has discovered a protein on the surface of lung cancer cells that could prove to be an important new target for anti-cancer therapy. A series of experiments in mice with lung cancer showed that specific targeting of the protein with monoclonal antibodies reduced the size of tumors, lowered the occurrence of metastases and substantially lengthened survival time.

Sea water strengthens the body against viruses, low defences, bacteria and pathogens

Sea water therapy is a technique of cellular nutrition backed by more than 100 years of clinical use in hospitals, during which numerous studies have demonstrated its beneficial effects on patients' health.

Study describes how Dbr1 gene halts toxic buildup of TDP-43-a protein

Scientists at the Gladstone Institutes and the Stanford University School of Medicine have discovered how modifying a gene halts the toxic buildup of a protein found in nerve cells. These findings point to a potential new tactic for treating a variety of neurodegenerative conditions, including amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease)-a fatal disease for which there is no cure.

New method of testing for West Nile virus

While the United States has largely been spared the scourge of mosquito-borne diseases endemic to the developing world-including yellow fever, malaria and dengue fever-mosquito-related illnesses in the US are on the rise. One pathogen of increasing concern in the U.S. is an arbovirus known as West Nile.

Research may lead to new ways to identify women with breast cancer risks from low-dose radiation

Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have identified tissue mechanisms that may influence a woman's susceptibility or resistance to breast cancer after exposure to low-dose ionizing radiation, such as the levels used in full-body CT scans and radiotherapy.

LRRK2 inhibitors may provide neuroprotection for patients with Parkinson's

For decades, patients with Parkinson's disease (PD) have had the same experience. Their hands start to shake uncontrollably, their limbs become rigid and they lose their balance. Years before those movement problems set in, many begin struggling with fainting, incontinence, sexual dysfunction, anxiety and depression. Many patients are still treated with a 42-year-old drug called L-DOPA, which temporarily staves off symptoms but can itself cause heart arrhythmias, stomach bleeding and hallucinations.

MD Anderson, Methodist create new 3D model for lung cancer research

A new technique that allows scientists to grow lung cancer cells in three dimensions could accelerate discoveries for a type of cancer that has benefited little from scientific research over the last several decades.

High-fat Western diet could lead to development of atherosclerosis

Columbia University Medical Center (CUMC) researchers have found that a diet high in saturated fat raises levels of endothelial lipase (EL), an enzyme associated with the development of atherosclerosis, and, conversely, that a diet high in omega-3 polyunsaturated fat lowers levels of this enzyme.

Scientists discover how protein deficiency may be linked to frontotemporal dementia

Using animal models, scientists at the Gladstone Institutes have discovered how a protein deficiency may be linked to frontotemporal dementia (FTD)-a form of early-onset dementia that is similar to Alzheimer's disease. These results lay the foundation for therapies that one day may benefit those who suffer from this and related diseases that wreak havoc on the brain.
