Tumor microenvironment contributes critically to drug response

It should be possible to significantly improve the response of common cancers to existing "classical" chemotherapy drugs, say scientists at Cold Spring Harbor Laboratory (CSHL), by introducing agents that alter the interaction of cancer cells with their immediate surroundings, called the tumor microenvironment.

Caring for wife with breast cancer can affect men's health

Caring for a wife with breast cancer can have a measurable negative effect on men's health, even years after the cancer diagnosis and completion of treatment, according to recent research.

Coronary stents do not increase risk of heart attack, death in people with metal allergies

Cardiologists have long grappled with how to best manage patients with coronary artery disease who report skin hypersensitivity to nickel or other metal components found in stents -- small tubes placed in narrowed or weakened arteries to help improve blood flow to the heart. But new Mayo Clinic research, published in the April 16, 2012, issue of Circulation: Cardiovascular Interventions, may help allay these concerns.

Study finds lower cytokine levels in the plasma of children with autism

A University of Kansas Medical Center study found significantly lower levels of several cytokines, the immune system's messengers and regulators, in the plasma of children with autism disorder (AD) compared to that of unrelated healthy siblings from other families who had members with autism spectrum disorders.

UCSF scientists assemble high-value genetic resource to help researchers

One of the ultimate ways of understanding what impact any particular gene has in human health or disease is to disrupt it-knocking it down or wiping it out in a worm, fly or mouse and gauging what happens next. Now scientists at the University of California, San Francisco (UCSF) Diabetes Center and the Gladstone Institute for Cardiovascular Disease have assembled a large publicly available resource to help researchers determine the importance of genes in mice and better gauge what roles they might play in disease.

Hydrophilic carbon cluster HADES can selectively kill brain cancer cells

Nanomedicine researchers at the Methodist Neurological Institute and Rice University have developed a way to selectively kill brain cancer cells by using a tiny syringe to deliver a combination of chemotherapy drugs directly into the cells. These findings will be published in the April 24 issue of the American Chemical Society journal ACS Nano.

UTHealth researcher studies novel cell therapy to prevent GVHD

A researcher at The University of Texas Health Science Center at Houston (UTHealth) is studying a novel cell therapy that could help avoid autoimmune problems after stem cell transplantation, as well as potentially treat other autoimmune diseases.

Steroids still work better for patients with sciatica

Despite the great promise that injecting a new type of anti-inflammatory pain medicine into the spine could relieve the severe leg and lower back pain of sciatica, a Johns Hopkins-led study has found that the current standard of care with steroid injections still does better.

Synthon receives tentative approval for tadalafil tablets

Synthon has announced that its subsidiary Synthon Pharmaceuticals, Inc. has received tentative approval from the U.S. Food and Drug Administration (FDA) for its abbreviated new drug application for tadalafil tablets, 20 mg on April 13, 2012. Synthon's product is a generic and bioequivalent version of Eli Lilly & Co and United Therapeutics’ Adcirca® tablets, which are indicated for the treatment of pulmonary arterial hypertension to improve exercise ability.

Salmonella link with yellowfin tuna: mass recall follows

A yellowfin tuna product used to make dishes like sushi, ceviche and sashimi sold at restaurants and grocery stores has been connected with with an outbreak of salmonella that has sickened more than 100 people in 20 states and the District of Columbia, federal health authorities announced last Friday.

Immunotherapy may also help elderly cancer patients

Cancer is much more likely in the elderly than the young, and their bodies often are less prepared to fight the disease and the often-toxic side effects of treatment.

TGF-β molecule ramps up the immune system in some cases and suppress it in others

Loyola researchers are reporting surprising findings about a molecule that helps ramp up the immune system in some cases and suppress it in others.

DEP exposure suppresses function of phagocytic immune cells

A team of researchers, led by Dr. Stephan Schwander, of the University of Medicine and Dentistry of New Jersey - School of Public Health (UMDNJ-SPH), has determined a possible link between exposure to a common component of urban air pollution and a change in the function of important immune cells that protect against the bacteria that cause tuberculosis.

Disruption of key cellular functions produces physiologic and behavioral responses

Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of animal cells trigger immune and detoxification responses, along with behavioral changes.

Flu shots offered to populations at risk at the beginning of season

All Care Inala Medical Centre doctor Michael Ho said flu shots were becoming more popular each year. “Flu seasons tends to begin in late March early April to June,” he said. “More and more people are opting to get vaccinations because they are promoted well within the community.” He added, “It is particularly important for elderly people to be immunized because their immune system is already not at its best…This is also the case for people who have chronic medical conditions like diabetes, severe asthma, or heart disease. With their current condition, if they catch the flu they can end up with a worse outcome.”

Researchers discover a lead on the origin of chronic lymphatic leukaemia

Up until now the causes of the development of chronic lymphatic leukaemia, the most common form of cancer of the blood in Europe, have been unknown. At present a cure is not possible. A research group at the MedUni Vienna led by Christoph Steininger of the University Department of Internal Medicine I has now however discovered a lead on the origin of this disease. Says Steiniger: "This could influence the therapy approach taken in treating chronic lymphatic leukaemia."

CLYD gene serves as crucial negative regulator in pulmonary fibrosis

An international team of researchers led by Georgia State University scientists have found a key component in the pathological process of pulmonary fibrosis, a fatal disease for which there is currently no cure.

New method for direct identification of antigens

The immune system is a vital part of our defenses against pathogens, but it can also attack host tissues, resulting in autoimmune disease. The antigens that induce destructive immune reactions can now be identified directly - without any prior knowledge of their possible structure.
