New polysaccharide may help combat multidrug resistance in cancer

In a recent study published in the Journal of Biological Chemistry, scientists report that a molecule previously thought to play a purely structural and inert role in cells is actually involved in multidrug resistance in cancer.

Allergies increase risk for corneal transplant rejection

Corneal transplant patients who suffer from eye allergies are at a significantly higher risk of transplant failure than those without allergies, UT Southwestern Medical Center researchers have shown.

Discovery may lead to new drugs to treat cancer, control fertility

A recent discovery in cellular biology may allow scientists to enhance organ regeneration by stem cells, prevent the progression of cancer, and control fertility.

Proof that chiropractic treatment helps migraine sufferers

Seventy-two per cent of migraine sufferers in a clinical trial experienced either 'substantial' or 'noticeable' improvement after a period of chiropractic treatment, defying historical skepticism of chiropractics by some medical practitioners.

Sunshine makes you feel good and may also help fight cancers

Although Vitamin D, the sunshine vitamin, gets little media attention, it is, surprisingly, a good tool in the fight against cancer.

Exercise programme is as beneficial as spinal surgery in treating lower back pain

The largest ever clinical trial of surgery versus exercise treatments for chronic low back pain has found that patients may obtain as much benefit from an intense physical exercise programme as from spinal surgery.

Crucial to develop set of protections for women who donate eggs to stem cell research

Now that stem cell researchers have devised an efficient way of creating new human embryonic stem cell lines, biomedical ethicists at the Stanford University School of Medicine say it's crucial to develop a unique set of protections for the women who donate their eggs to make the research possible.

Gene keeps neural cells on correct developmental path

Embryonic stem cells with identical genomes grow into distinctive tissues, such as heart, bone, and brain. At one time, scientists believed the differences among cell types arose from various sets of genes switched on inside developing cells. Then, studies showed that adult neurons uniquely lack a protein that permanently turns off neuronal genes in the rest of the body's cells.

Dextromethorphan temporarily reduces the intensity of fibromyalgia

Dextromethorphan, an over-the-counter medication that silences coughs, may help fibromyalgia patients quiet over-reacting nerves that amplify ordinary touches into agony.

Researchers generate patient-specific stem cells

Researchers have isolated the first human embryonic stem cell lines specifically tailored to match the nuclear DNA of patients, both males and females of various ages, suffering from disease or spinal cord injury.

FDA recommends approval of the investigational anti-HIV drug tipranavir

Boehringer Ingelheim today announced that the U.S. Food and Drug Administration's (FDA) Antiviral Drugs Advisory Committee recommended the approval of the investigational anti-HIV drug tipranavir (11-3). Tipranavir is a non-peptidic protease inhibitor that requires boosting with low-dose ritonavir and must be used in combination with other antiretroviral agents.

Study holds implications for gene therapy and stem cell biology

The study, conducted by scientists from Cincinnati Children's Hospital Medical Center, and Hannover Medical School and Hamburg University in Germany, reveals important evidence that tells us more about how blood forming stem cells regenerate. On the other hand, scientists offer caution in regards to the side effects associated with genetic engineering of stem cells.

Physiotherapy is effective in treating stress incontinence

Physiotherapy is effective in treating stress incontinence in about 80 per cent of cases, according to the first national study undertaken in clinical practice by researchers at the University of South Australia.

Judges perceive child witnesses as being more honest than adults when testifying in court

The multi-disciplinary research, the first of its kind to examine judges' perceptions of child witnesses, was led by Queen's Child and Family Law scholar Nick Bala. It addresses how judges assess the honesty and reliability of children's court testimony, and how accurate their observations are.

Nurture as important as nature in developing ability for flexible self-control

Your ability to follow the rules of the road when driving on unfamiliar streets exists thanks to the way your pre-teen life experiences influenced the development of your brain. Individuals deprived of normal life experiences may lack this ability to control their behavior in novel situations, a new computer model suggests, providing insight into how nature and nurture may interact in the development of self-control.

Merck cervical cancer virus vaccine performs well

Drugmaker Merck & Co. Inc. on Thursday said its investigational vaccine against a sexually transmitted virus linked to cervical cancer triggered a stronger immune response in young adolescents than in young women in a late-stage trial.

So you thought that smell was cheese!

Researchers in the UK have found that visual words can influence the perception of smells, with pleasant words influencing olfactory brain regions to perceive an odour as pleasant, an interesting idea that might hold particular relevance for restaurateurs and advertisers.

Extolling the safety of childhood vaccinations may only serve to strengthen the positions of those philosophically opposed to them

"Changing attitudes about pediatric vaccination can be challenging," says Dr. Kumanan Wilson, professor of medicine and health policy, management and evaluation at U of T, internal medicine physician at Toronto General Hospital, University Health Network, and lead author of the research.

Drug used to treat enlarged prostate may improve the accuracy of prostate biopsies

The drug, dutasteride, suppresses blood flow in benign tissue of the prostate, allowing radiologists to better target cancer tissue using Doppler ultrasound, said Elizabeth Ives, MD, a research fellow at Thomas Jefferson University Hospital in Philadelphia and lead author of the study.

Cetuximab (Erbitux) can battle cancer and prolong life in many patients with advanced colorectal cancer

"Even in people who have gone through six or more previous courses of chemotherapy, cetuximab, may fight the growth of cancer, giving patients additional months of life," says study presenter Heinz-Josef Lenz, M.D., associate professor of medicine at the Keck School of Medicine of the University of Southern California and USC/Norris Comprehensive Cancer Center.
