Potential new drug target for preventing postmenopausal bone loss

Scientists have discovered new information about an immune pathway in mice that explains how oxidative stress that results from acute estrogen deficiency leads to the loss of bone.

Tendons found to contain a small subset of previously unknown adult stem cells

Tendon, the cord-like tissue that connects muscle to bone, contains a small subset of previously unknown adult stem cells, scientists at the National Institute of Dental and Craniofacial Research (NIDCR) part of the National Institutes of Health, and their colleagues have discovered.

Scientists shed new light on how antibodies fight HIV

By furthering scientists' understanding of the molecular mechanisms that separate the minority of successful HIV antibodies from the majority of ineffective antibodies, the work may have implications for future attempts to design an HIV vaccine.

Discovery of tendon cells that self-renew

Athletes know that damage to a tendon can signal an end to their professional careers. But a consortium of scientists, led in part by USC School of Dentistry researcher Songtao Shi, has identified unique cells within the adult tendon that have stem-cell characteristics - including the ability to proliferate and self-renew.

New technique for growing cartilage from human embryonic stem cells

Rice University biomedical engineers have developed a new technique for growing cartilage from human embryonic stem cells, a method that could be used to grow replacement cartilage for the surgical repair of knee, jaw, hip, and other joints.

Scientists speed healing of bone damage

Blocking a naturally occurring inhibitor of bone formation accelerates healing of skull defects in mice, say researchers at the Stanford University School of Medicine and Lucile Packard Children's Hospital. The finding advances the understanding of how the skeleton develops and opens new therapeutic avenues for many of the disorders that are expected to afflict aging baby boomers.

Myoendothelial cells identified as new human source of stem cells with potential to repair muscle

For the first time, scientists at Children's Hospital of Pittsburgh of UPMC have discovered a unique population of adult stem cells derived from human muscle that could be used to treat muscle injuries and diseases such as heart attack and muscular dystrophy.

20 percent of overweight toddlers found to be iron-deficient

A study by UT Southwestern Medical Center researchers has found that overweight toddlers and those not enrolled in day care are at high risk for iron deficiency.

Benefits and limitations of health tests offered in community settings

Consumers who queue up for health screenings at the mall, a senior center, a drug store or other retail business could benefit from the information they learn.

Revlimid receives approval in Switzerland for treatment of multiple myeloma

Celgene International Sarl has announced that it's oral cancer drug, Revlimid (lenalidomide) has been granted approval by the Swiss Agency for Therapeutic Products (Swissmedic) for use in combination with dexamethasone as a treatment for patients with multiple myeloma who have received at least one prior therapy.

Study identifies osteopontin as a key player in the body's immune response to chronic stress

Osteopontin (OPN), a protein molecule involved in many different cellular processes, plays a significant role in immune deficiency and organ atrophy following chronic physiological stress, resulting in increased susceptibility to illness.

Taking paracetamol slows down bone growth

In Medicine, paracetamol is used to soothe every kind of pain, from simple molar pain to pain produced by bone fractures.

Mice stressed in simulated weightlessness show organ atrophy

A ground-based, experimental model used to simulate astronaut weightlessness in space has provided Rutgers scientists an opportunity to study the effects of stress on immune organs.

FDA approves Acambis smallpox vaccine

Acambis plc (Acambis) has announced that the US Food and Drug Administration (FDA) has approved its ACAM2000 (Smallpox (Vaccinia) Vaccine, Live) vaccine for protection against smallpox.

Symposium on children born with clubfoot

We often think that high-tech, surgical methods are the best approach when it comes to medical care. But for children born with clubfoot, there is growing, worldwide interest in a low-tech, non-surgical method of treatment that is more effective, less expensive and easier to provide than surgery.

Greater use of spinal fusion has not lowered risk of repeat back surgery

Despite new implant technologies and surgical techniques leading to increased rates of spinal fusion surgery, the percentage of patients requiring further low-back surgery after spinal fusion has actually increased since the early 1990s, reports the Sept. 1 issue of the journal Spine, published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Does physical activity provide a molecular key to longevity?

Fitness and physical exercise are among the most neglected means to improve prognosis. They are the healthiest cardiovascular intervention. Even cardiologists focus on pharmacological treatment and evaluate classical risk factors without asking about daily exercise or objective measures of physical capacity. It is surprising considering the strong data that underscores the survival benefit of regular exercise training.

Discovery of novel cause of iron overload in patients with thalassemia

According to the study, thalassemia patients overproduce a protein called GDF15, which suppresses the production of a liver protein, hepcidin, which in turn leads to an increase in the uptake of dietary iron in the gut.

New insights into knee injuries and osteoarthritis in the knee

The sort of swelling that occurs when a joint is damaged by injury or degeneration is normally essential to the healing process, but when it comes to the knee, that inflammation can actually interfere with healing.

New anti-cancer drug made from corn lillies kills brain tumor stem cells

A drug that shuts down a critical cell-signaling pathway in the most common and aggressive type of adult brain cancer successfully kills cancer stem cells thought to fuel tumor growth and help cancers evade drug and radiation therapy, a Johns Hopkins study shows.
