Vitamin C inhibits the growth of some tumors

Nearly 30 years after Nobel laureate Linus Pauling famously and controversially suggested that vitamin C supplements can prevent cancer, a team of Johns Hopkins scientists have shown that in mice at least, vitamin C - and potentially other antioxidants - can indeed inhibit the growth of some tumors ¯ just not in the manner suggested by years of investigation.

GP prescribing of antibiotics in question

GPs prescribing antibiotics often rely on their personal preferences and experience, rather than clinical evidence, says new research launched at the British Pharmaceutical Conference (BPC) in Manchester.

Mechanism identified that plays a critical role in multiple myeloma cell cycle and survival

Researchers at Emory University's Winship Cancer Institute are the first to discover a mechanism that plays a critical role in the multiple myeloma cell cycle and survival.

Shaken not stirred for embryonic stem cells

Embryos spend much of their time in the womb bobbing along with a mother's movement, and, surprisingly enough, new research from the Georgia Institute of Technology and Emory University suggests that embryonic stem cells may develop much better under similarly shaky conditions.

Being overweight may independently increase risk for developing coronary heart disease

Being moderately overweight or obese appears to increase the risk for developing coronary heart disease events independent of traditional cardiovascular risk factors, according to a meta-analysis of previously published studies in the September 10 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Antidepressant citalopram shows promise in treating symptoms of dementia

Researchers have found surprising evidence that an antidepressant (citalopram) may perform as well as a commonly-prescribed antipsychotic (risperidone) in the alleviation of severe agitation and psychotic symptoms of dementia.

Coding and noncoding genes are involved in and cooperate in human tumorigenesis

A new study provides evidence that noncoding RNAs and interactions between noncoding genes play a much greater role in human cancer than was previously understood.

Two drugs equally effective for heart patients undergoing angioplasty

In lifesaving procedures to open blocked heart arteries a key question has persisted for years: Is use of the more expensive drug, abciximab, justified over use of the less-expensive eptifibatide

Occupational vocal cord dysfunction

Researchers from the UAB and the Vall d'Hebron Hospital have diagnosed two patients affected with vocal cord dysfunction, which causes coughing and difficulty in breathing due to irritating agents that are breathed in at the workplace.

Genetic causes of rheumatoid arthritis

The human genome has now been thoroughly screened in the hunt for the genetic causes of rheumatoid arthritis. The results, which both confirms previous hypotheses and turn the spotlight on entirely new genes, are presented in two articles in the prestigious New England Journal of Medicine.

Women more at risk from sleep deprivation than men

New research led by researchers at Warwick Medical School at the University of Warwick reveals that women's health is much more at risk from sleep deprivation than men's.

New genetic risk factor for rheumatoid arthritis and lupus

A genetic variation has been identified that increases the risk of two chronic, autoimmune inflammatory diseases: rheumatoid arthritis (RA) and systemic lupus erythematosus (lupus).

Congestive heart failure is rare among leukemia patients who take imatinib

Congestive heart failure rarely occurs among leukemia patients who take imatinib, researchers at The University of Texas M. D. Anderson Cancer Center found after an exhaustive review of the detailed medical histories of 1,276 patients who enrolled in clinical trials for the drug.

Researchers make new discovery on pigment melanin and skin - hair color

The pigment melanin, which is responsible for skin and hair color in mammals, is produced in specialized cells called melanocytes and then distributed to other cells. But not every cell in the complex layers of skin becomes pigmented.

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.

Schizophrenia-linked gene keeps new adult brain cells under control

The study reveals that the gene, known as Disrupted-In-Schizophrenia 1 (DISC1), directs the incorporation of new neurons into the adult brain and keeps the process under control. The gene's newly discovered roles might help to explain why schizophrenia's symptoms generally arise in adolescence or early adulthood, the researchers suggested.

Innovative liquid crystal technology offers promise of new drugs

A partnership between Kent State University, Summa Health System and IC-MedTech Inc. has yielded an innovative liquid crystal technology that offers the promise of new drugs which may more effectively manage cancer and other diseases.

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.
