Women with heart attack symptoms receive lower quality of care than men

A new study published recently in the American Journal of Medicine, conducted by researchers in the Cardiac and Vascular Institute at NYU Langone Medical Center, found there was significantly lower quality of care and worse outcomes in women compared to men - particularly young women under age 35 who had heart attack symptoms.

Newly discovered on/off switch in enzymes may help battle fat-related disease

Enzymes involved in breaking down fat can now be manipulated to work three times harder by turning on a molecular switch recently observed by chemists at the University of Copenhagen. Being able to control this chemical on/off button could have massive implications for curing diseases related to obesity including diabetes, cardio vascular disease, stroke and even skin problems like acne. But the implications may be wider.

Study identifies how RNA viruses hijack a host cell to multiply

By discovering how certain viruses use their host cells to replicate, UC Irvine microbiologists have identified a new approach to the development of universal treatments for viral illnesses such as meningitis, encephalitis, hepatitis and possibly the common cold.

Researchers report how Alzheimer's protein deposits disrupt signalling between nerve cells

How abnormal protein deposits in the brains of Alzheimer's patients disrupt the signalling between nerve cells has now been reported by researchers in Bochum and Munich, led by Dr. Thorsten M-ller from the Medizinisches Proteom-Center of the Ruhr-Universit-t, in the journal Molecular and Cellular Proteomics. They varied the amount of APP protein and related proteins associated with Alzheimer's disease in cell cultures, and then analysed how this manipulation affected other proteins in the cell.

IntelliCell seeks patent for new mechanical method to separate SVF from blood vessels in fat

IntelliCell BioSciences, Inc. announced today that it has filed a patent application for a new mechanical method to separate stromal vascular fraction (SVF) from the blood vessels in adipose tissue (fat) to be used clinically in regenerative medicine.

Berry wines may help people with diabetes decrease their blood sugar

In evaluating the bioactive compounds of Illinois blueberry and blackberry wines, University of Illinois scientists have found compounds that inhibit enzymes responsible for carbohydrate absorption and assimilation. And that could mean a tasty way to help people with diabetes decrease their blood sugar.

Medivir initiates MIV-711 phase Ib trial in healthy volunteers

Medivir AB, the research-based pharmaceutical company focused on the development of high-value treatments for infectious diseases, is reporting today that a clinical phase Ib trial of the company's candidate drug (CD) MIV-711 has commenced.

Protein toxic to nerve cells in AD also contributes to memory loss

The underlying causes of Alzheimer's disease are not fully understood, but a good deal of evidence points to the accumulation of β-amyloid, a protein that's toxic to nerve cells. β-amyloid is formed by the activity of several enzymes, including one called BACE1. Most Alzheimer's disease patients have elevated levels of BACE1, which in turn leads to more brain-damaging β-amyloid protein.

New birth-control strategy for mosquitoes can combat malaria

Using information about the unique mating practices of the male malaria mosquito ― which, unlike any other insect, inserts a plug to seal its sperm inside the female ― scientists are zeroing in on a birth-control drug for Anopheles mosquitoes, deadly carriers of the disease that threatens 3 billion people, has infected more than 215 million and kills 655,000 annually.

U.S. DOE’s Oak Ridge National Laboratory develops new carbon cycling model

A new carbon cycling model developed at the U.S. Department of Energy's (DOE) Oak Ridge National Laboratory better accounts for the carbon dioxide-releasing activity of microbes in the ground, improving scientists' understanding of the role soil will play in future climate change.

Rhomboid enzymes and malaria treatment: an interview with Sinisa Urban

Rhomboid enzymes live in the cell’s membrane where their job is to cut the anchors of proteins, which releases the target proteins from the membrane.

Passenger deletions that deactivate essential genes provide new opportunity to strike cancer

Genomic deletions promote cancer by carving up or eliminating tumor-suppressor genes, but now scientists report in the journal Nature that the collateral damage they inflict on neighboring genes exposes cancer cells to vulnerabilities and new avenues for attack.

Cancer patients with xerostomia can benefit from regenerative research

Biologists, surgical oncologists and regenerative medicine specialists from Rice University, the University of Delaware and the Christiana Care Health System in Wilmington, Del., have begun a four-year program aimed at using cells to grow whole salivary glands that can replace those destroyed by cancer radiation therapy.

Blocking PHD2 oxygen sensor can render cancer treatments more effective

Researchers in Leuven (VIB/KU Leuven) have confirmed their hypothesis that normalizing blood vessels by blocking oxygen sensor PHD2 would make chemotherapy more effective.

Study investigates ability of bifidobacteria to remove glycans from milk glycoproteins

A research team at the University of California, Davis, has found that important and resourceful bacteria in the baby microbiome can ferret out nourishment from a previously unknown source, possibly helping at-risk infants break down components of breast milk.

Glioblastoma patients with modified PTEN have resistance to EGFR inhibitors

Despite years of research, glioblastoma, the most common and deadly brain cancer in adults, continues to outsmart treatments targeted to inhibit tumor growth.

Cathepsins may attack one another instead of the bodily proteins

Researchers for the first time have shown that members of a family of enzymes known as cathepsins - which are implicated in many disease processes - may attack one another instead of the bodily proteins they normally degrade. Dubbed "cathepsin cannibalism," the phenomenon may help explain problems with drugs that have been developed to inhibit the effects of these powerful proteases.

Antisense therapy shows promise in treating toxoplasmosis

A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences.

Researchers identify key element in the development of Burkitt lymphoma

Burkitt lymphoma is a malignant, fast-growing tumor that originates from a subtype of white blood cells called B lymphocytes of the immune system and often affects internal organs and the central nervous system. Now Dr. Sandrine Sander and Professor Klaus Rajewsky of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have identified a key element that transforms the immune cells into malignant lymphoma cells.
