BCX4945 proves effective at clearing malaria infections

An antimalarial agent developed by researchers at Albert Einstein College of Medicine of Yeshiva University proved effective at clearing infections caused by the malaria parasite most lethal to humans - by literally starving the parasites to death. The novel research, carried out on a small number of non-human primates, could bolster efforts to develop more potent therapies against one of the world's leading killers.

Botulism toxins could be re-engineered for treating RA, asthma, psoriasis

The most poisonous substance on Earth - already used medically in small doses to treat certain nerve disorders and facial wrinkles - could be re-engineered for an expanded role in helping millions of people with rheumatoid arthritis, asthma, psoriasis and other diseases, scientists are reporting. Their study appears in ACS' journal Biochemistry.

Study explores critical role of 14-3-3σ in halting breast cancer progression

New research out of McGill University's Goodman Cancer Research Centre provides compelling new evidence that a gene known as 14-3-3σ plays a critical role in halting breast cancer initiation and progression.

Herbicide atrazine linked to reproductive dysfunction

An international team of researchers has reviewed the evidence linking exposure to atrazine - an herbicide widely used in the U.S. and more than 60 other nations - to reproductive problems in animals. The team found consistent patterns of reproductive dysfunction in amphibians, fish, reptiles and mammals exposed to the chemical.

Knocking out one copy of IGF1 receptor fails to increase life span of male mice

Scientists studying longevity thought it might be good to lack a copy of a gene, called IGF1 receptor, that is important in insulin signaling. Previous studies showed invertebrates that lacked the copy lived longer, even if their bodies were less responsive to insulin, the hormone that lowers blood sugar.

BUSM professor receives 2011 ACN Communication Media Award

Michael F. Holick, PhD, MD, director of the General Clinical Research Unit and professor of medicine, physiology and biophysics at Boston University School of Medicine (BUSM) was selected by the American College of Nutrition (ACN) Awards Committee as the 2011 recipient of the ACN Communication Media Award.

JIB highlights aluminium's potential role in neurodegenerative diseases

Aluminium's potential role in neurodegenerative diseases such as Alzheimer's disease and cancer, specifically breast cancer, and the potential role for aluminium adjuvants in vaccine-related adverse effects are spotlighted in the latest issue of the Journal of Inorganic Biochemistry (JIB).

New procedure could be adapted for use with X-ray techniques in studying human health

For more than a century, the use of X-rays has been a prime diagnostic tool when it comes to human health. As it turns out, X-rays also are a crucial component for studying and understanding molecules, and a new approach -- just published by researchers at the University of Georgia -- may dramatically improve what researchers can learn using the technique.

Biochemists identify structure of hydroxyurea that specifically inhibits proteasome

As the "recycling plant" of the cell, the proteasome regulates vitally important functions. When it is inhibited, the cell chokes on its own waste. Cancer cells, in particular, are very sensitive because they need the proteasome for their uncontrolled growth. Biochemists at the Technische Universitaet Muenchen (TUM) have now identified the lead structure of a new class of drugs that attacks the proteasome in an unusual way. New medication could be developed on the basis of this previously unknown binding mechanism.

Clinical value of OrSense NBM 200 non-invasive Hb monitor for maternal health to be presented at 4th COGI

OrSense Ltd., announced today that two oral presentations on the clinical value of its NBM 200 non-invasive hemoglobin (Hb) monitor for maternal health and anemia monitoring prior, during and post delivery of pregnant women will be presented at the 4th Asia Pacific Congress on Controversies in Obstetrics Gynecology and Infertility (COGI).

H2S plays a major role in protecting bacteria from effects of different antibiotics

Although scientists have known for centuries that many bacteria produce hydrogen sulfide (H2S) it was thought to be simply a toxic by-product of cellular activity. Now, researchers at NYU School of Medicine have discovered H2S in fact plays a major role in protecting bacteria from the effects of numerous different antibiotics.

Human pluripotent stem cells rely heavily on glycolysis to drive their metabolic activities

Human pluripotent stem cells, which can develop into any cell type in the body, rely heavily on glycolysis, or sugar fermentation, to drive their metabolic activities.

Researchers discover human genes that might contribute to ALS

Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a universally fatal neurodegenerative disease. Mutations in two related proteins, TDP-43 and FUS, cause some forms of ALS. Specifically, these two proteins are RNA-binding proteins that connect to RNA to regulate the translation of proteins and other cellular functions such as RNA splicing and editing. In a new study, researchers at the Perelman School of Medicine at the University of Pennsylvania discovered additional human genes with properties similar to TDP-43 and FUS that might also contribute to ALS.
