Scientists identify how virus triggers cervical and mouth cancer

University of Manchester scientists have discovered for the first time an important new way in which the human papilloma virus (HPV) triggers cancer in what could lead to new treatments for cervical and mouth cancer.

HPV infection is known to increase the risk of developing cancers of the cervix and mouth with the two high-risk forms of the virus accounting for approximately 70% of all cervical cancer cases.

Unique orangutan reintroduction project under imminent threat

JAMBI, Indonesia – A Sumatran rainforest named a global priority for tigers and home to a unique orangutan rescue project is targeted for clearcutting by one of the world's largest paper suppliers.

The stemness of cancer cells

The stemness of cancer cells

LA JOLLA, CA-A close collaboration between researchers at the Salk Institute for Biological Studies and the Institute for Advanced Study found that the tumor suppressor p53, long thought of as the "Guardian of the Genome," may do more than thwart cancer-causing mutations. It may also prevent established cancer cells from sliding toward a more aggressive, stem-like state by serving as a "Guardian against Genome Reprogramming."

Nano-measurement of troponin levels proves an accurate predictor of deterioration in heart failure

Sophia Antipolis, 14 December 2010: Today, heart failure is by far the single biggest reason for acute hospital admission. Around 30 million people in Europe have heart failure and its incidence is still increasing: more cases are being identified, more people are living to an old age, and more are surviving a heart attack but with damage to the heart muscle. Yet traditional risk-factor prediction models have only limited accuracy in this population to identify those at highest risk for worsening outcomes.

Smoking behind more than a third of severe rheumatoid arthritis cases

Smoking accounts for more than a third of cases of the most severe and common form of rheumatoid arthritis, indicates research published online in the Annals of the Rheumatic Diseases.

And it accounts for more than half of cases in people who are genetically susceptible to development of the disease, finds the study.

UK ill prepared for 'epidemic' of degenerative valvular heart disease

The UK is poorly prepared for the forthcoming epidemic of degenerative valvular heart disease, prompted by a rapidly ageing population, say leading experts in the journal Heart.

The prevalence of valvular heart disease, or VHD for short, rises with age. European and US data indicate that more than 13% of those aged 75 and above have the progressive condition. And by 2018, there will be an estimated 4 million people in the UK aged between 75 and 84.

UK medical student ophthalmology teaching falling short

UK medical schools are failing to comply with the recommended curriculum for ophthalmology, set out by the International Council of Ophthalmologists (ICO), suggests a survey published online in the British Journal of Ophthalmology.

Amid concerns that the specialty was being squeezed out of undergraduate education, the council urged medical schools to make it a core subject and produced guidance to help them do this.

Ovarian cancer clue: Methylation-mediated suppression of a key pathway is found

December 14, 2010 – Ovarian cancer is the leading cause of death among gynecological cancers. To better understand the disease and improve therapies, researchers are investigating how deregulation of genes across the genome could be contributing to malignancy.

Ovarian cancer advances when genes are silenced

DURHAM, N.C. – There are many mechanisms that alter the activity of genes – direct changes to the DNA code like mutations and deletions, or changes that control when genes are switched on and off, called epigenetic means. Tumor-suppressor genes are often inactivated through epigenetics, which provides an opening for the cancerous growth of cells.

Drought and rising temperatures weaken southwest forests

ALBANY, Calif.—Forests in the southwestern United States are changing and will face reduced growth if temperatures continue to rise and precipitation declines during this century, according to a study conducted by a team of scientists from the U.S. Forest Service; University of California, Santa Barbara; U.S. Geological Survey; and University of Arizona. Their findings were released today in the Proceedings of the National Academy of Sciences (PNAS) special issue on climate change.

Many brain tumor patients use homeopathy, alternative treatments

ST. PAUL, Minn. – Many people with incurable brain tumors use alternative therapies, such as taking vitamins and homeopathy, in addition to their conventional treatments, according to a study published in the December 14, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology.

About 40 percent of brain tumor patients in the study used alternative therapies including homeopathic remedies, vitamin supplements and psychological therapy.

Soda taxes: Weight loss benefit linked to household income

DURHAM, N.C. – Imposing higher taxes on sodas and other sweetened drinks may generate a lot of money – but would lead to only minimal weight loss among most people and would have no effect on weight among consumers in the highest and lowest income groups, according to new research from Duke-National University of Singapore (NUS) Graduate Medical School.

Targeted messages may encourage some patients to get colorectal cancer screenings

Personalized electronic messages to patients overdue for screenings, or mailings targeted to patients with expired orders for colonoscopies, may each increase colorectal cancer screening rates over the short term, according to two reports posted online today that will be published in the April 11 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

High levels of 'good' cholesterol may be associated with lower risk of Alzheimer's disease

High levels of high-density lipoprotein (HDL), also known as "good" cholesterol, appear to be associated with a reduced risk for Alzheimer's disease in older adults, according to a report in the December issue of Archives of Neurology, one of the JAMA/Archives journals.
