Cannabinoids may be a target for new strategies in cancer treatment

Cannabis-like substances that are produced by the body have both therapeutic and harmful properties, besides their well-known intoxicating effects, and the body's cannabinoid system may be a target for new strategies in cancer treatment.

Genome sequencing helps characterize S. aureus ST398-NM strain

Using genome sequencing and household surveillance, National Institutes of Health (NIH) scientists and their colleagues from Columbia University Medical Center and St. George's University of London have pieced together how a newly emerging type of Staphylococcus aureus bacteria has adapted to transmit more easily among humans.

Scientists discover new pathway necessary for infection to occur with N. gonorrhoeae

Researchers from Boston University School of Medicine (BUSM) have for the first time identified a novel pathway that is necessary for infection to occur with the pathogen Neisseria gonorrhoeae, which is responsible for the second most common infectious disease worldwide, gonorrhea.

Low and high ID50 bacteria act through stealth and frontal attack

Why is it that Mycobacterium tuberculosis can cause tuberculosis with as little as 10 cells, whereas Vibrio cholerae requires the host to ingest up to tens of millions of cells to cause cholera? This is the question that two research teams, from the Pasteur Institute, in France, and the Instituto Gulbenkian de Ciencia and the University of Lisbon, in Portugal, answer in the latest issue of the journal PLoS Pathogens.

Study identifies new processes that lead to development of novel cell implicated in allergies

A collaboration between scientists in Trinity College Dublin and the United Kingdom has identified new processes that lead to the development of a novel cell implicated in allergies. The discovery has the potential for new strategies to treat asthma and other allergic diseases.

Octapharma submits octaplasLG BLA with FDA to treat TTP

Octapharma USA has submitted its Biological License Application (BLA) for octaplasLG to the U.S. Food and Drug Administration (FDA) with the goal of expanding its U.S. product portfolio by the fourth quarter of 2012.

Chemically altered osteoporosis drug may fight malaria

A chemically altered osteoporosis drug may be useful in fighting malaria, researchers report in a new study. Unlike similar compounds tested against other parasitic protozoa, the drug readily crosses into the red blood cells of malaria-infected mice and kills the malaria parasite. The drug works at very low concentrations with no observed toxicity to the mouse.

New RNA interference method holds promise for cancer, other diseases

For the past decade, scientists have been pursuing cancer treatments based on RNA interference - a phenomenon that offers a way to shut off malfunctioning genes with short snippets of RNA. However, one huge challenge remains: finding a way to efficiently deliver the RNA.

Cross-protective vaccines will make a bout with influenza less severe

An emerging class of long-lasting flu vaccines could do more than just save people the trouble of an annual flu shot.

Death of myelin sheath producing cells does not trigger MS

Millions of adults suffer from the incurable disease multiple sclerosis (MS). It is relatively certain that MS is an autoimmune disease in which the body's own defense cells attack the myelin in the brain and spinal cord.

Ovaries of reproductive-age women possess egg precursor cells that can mature into eggs

OvaScience, a fertility company focused on the discovery, development and commercialization of novel treatments for infertility, today announced the publication of results demonstrating that ovaries of reproductive-age women possess egg precursor cells that can mature into eggs.

MGH scientists isolate OSCs from ovaries of reproductive age women

For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

New technique effective in jumpstarting defective immune systems against many diseases

In a study published in Nature Medicine, Loyola researchers report on a promising new technique that potentially could turn immune system killer T cells into more effective weapons against infections and possibly cancer.

Seven scientists aim to make strides in predicting and preventing preterm birth

With the help of funding from the March of Dimes, researchers from five states and Canada are seeking answers to questions such as how cellular-level processes that control uterine muscles may affect preterm labor, the causes of preeclampsia, and how air pollution may affect pregnancy and preterm birth - all with the goal of preventing preterm birth so more babies will get a healthy start in life.

Fetus protecting enzyme also prevents autoimmune diseases

Cells that die naturally generate a lot of internal debris that can trigger the immune system to attack the body, leading to diseases such as lupus.

Study evaluates how environmental triggers might alter epigenetics of CFS

A University of Toronto Scarborough (UTSC) researcher is examining how environmental triggers might alter gene function in people with Chronic Fatigue Syndrome. The research could lead to better insights into the disease and eventually to new treatments.

Article in journal Science proposes new look on killer diseases

The immune system protects from infections by detecting and eliminating invading pathogens. These two strategies form the basis of conventional clinical approaches in the fight against infectious diseases.

Scientists identify specific pathways behind breast cell's transformation into cancer

Although it's widely accepted that inflammation is a critical underlying factor in a range of diseases, including the progression of cancer, little is known about its role when normal cells become tumor cells. Now, scientists from the Florida campus of The Scripps Research Institute have shed new light on exactly how the activation of a pair of inflammatory signaling pathways leads to the transformation of normal breast cells to cancer cells.

Scientists decode two new blood types

You probably know your blood type: A, B, AB or O. You may even know if you're Rhesus positive or negative. But how about the Langereis blood type? Or the Junior blood type? Positive or negative? Most people have never even heard of these.
