New method to manage stress responses for more successful tumor removal

The week before and two weeks after surgery are a critical period for the long-term survival rate of cancer patients. Physiological and psychological stresses caused by the surgery itself can inhibit the body's immune responses, heightening vulnerability to tumor progression and spreading.

Alcohol consumption and risk of colon cancer in people with a family history of such cancer

A study based on more than 87,000 women and 47,000 men in the Nurses' Health Study and the Health Professionals Follow-up Study, looks at whether there is a link between colon cancer and alcohol, and if so at what level of consumption, and the importance of a family history of the disease. A total of 1,801 cases of colon cancer were diagnosed during follow-up from 1980 onwards.

Barrett's patients who smoke twice as likely to develop oesophageal cancer

Smoking doubles the risk of developing oesophageal cancer in people with Barrett's Oesophagus, according to scientists at Queen's University Belfast and the Northern Ireland Cancer Registry.

Affecting one in every 100 people in the UK, Barrett's Oesophagus is a disorder in which the lining of the oesophagus is damaged by stomach acid and is changed to a lining similar to that of the stomach.

New guidelines to prevent infection in minor surgery

London -- New guidelines from the Healthcare Infection Society (HIS) aimed at minimising surgical infection in day centres and primary care are now published in the Journal of Hospital Infection.

Rice professor's nanotube theory confirmed

The Air Force Research Laboratory in Dayton, Ohio, has experimentally confirmed a theory by Rice University Professor Boris Yakobson that foretold a pair of interesting properties about nanotube growth: That the chirality of a nanotube controls the speed of its growth, and that armchair nanotubes should grow the fastest.

Divorce hurts health more at earlier ages

EAST LANSING, Mich. -- Divorce at a younger age hurts people's health more than divorce later in life, according to a new study by a Michigan State University sociologist.

Hui Liu said the findings, which appear in the research journal Social Science & Medicine, suggest older people have more coping skills to deal with the stress of divorce.

In lab, Pannexin1 restores tight binding of cells that is lost in cancer

PROVIDENCE, R.I. [Brown University] -- First there is the tumor and then there's the horrible question of whether the cancerous cells will spread. Scientists increasingly believe that the structural properties of the tumor itself, such as how tightly the tumor cells are packed together, play a decisive role in the progression of the disease. In a new study, researchers show that the protein Pannexin1, known to have tumor-suppressive properties, plays an important role in keeping the cells within a tissue closely packed together, an effect that may be lost with cancer.

Alcohol and your heart: Friend or foe?

For immediate release -- A meta-analysis done by the Centre for Addiction and Mental Health (CAMH) into the relationship between alcohol consumption and heart disease provides new insight into the long-held belief that drinking a glass of red wine a day can help protect against heart disease.

Barrett's patients who smoke are twice as likely to develop esophageal cancer

Barrett's esophagus (BE) patients who smoke tobacco are at a two-fold increased risk of developing esophageal cancer, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association. BE patients who smoke also double their risk for developing advanced precancerous cells.

Need muscle for a tough spot? Turn to fat stem cells, UC San Diego researchers say

Stem cells derived from fat have a surprising trick up their sleeves: Encouraged to develop on a stiff surface, they undergo a remarkable transformation toward becoming mature muscle cells. The new research appears in the journal Biomaterials. The new cells remain intact and fused together even when transferred to an extremely stiff, bone-like surface, which has University of California, San Diego bioengineering professor Adam Engler and colleagues intrigued. These cells, they suggest, could hint at new therapeutic possibilities for muscular dystrophy.

Sexual healing? Not likely

A new study shows the production of sperm is more biologically taxing than previously thought, and expending energy on it has significant health implications.

In research published in PLoS ONE, Dr Damian Dowling of Monash University's School of Biological Sciences and Professor Leigh Simmons of the University of Western Australia have investigated the trade-off between sperm quality and immunity.

Warming in the Tasman Sea a global warming hot spot

Oceanographers have identified a series of ocean hotspots around the world generated by strengthening wind systems that have driven oceanic currents, including the East Australian Current, polewards beyond their known boundaries.

The hotspots have formed alongside ocean currents that wash the east coast of the major continents and their warming proceeds at a rate far exceeding the average rate of ocean surface warming, according to an international science team whose work is published in the journal Nature Climate Change today.

Ultrasound male contraceptive, overlooked for decades, confirmed to work

Imagine a contraceptive that could, with one or two painless 15-minute non-surgical treatments, provide months of protection from pregnancy. And imagine that the equipment needed were already in physical therapists' offices around the world.

UCSB researchers discover the processes leading to acute myeloid leukemia

Santa Barbara, Calif. –– Researchers at UC Santa Barbara have discovered a molecular pathway that may explain how a particularly deadly form of cancer develops. The discovery may lead to new cancer therapies that reprogram cells instead of killing them. The findings are published in a recent paper in the Journal of Biological Chemistry.

Jak of all trades? Not of leukaemia therapy!

About one in five or six cases of adult leukaemia in Western populations relates to so-called chronic myeloid leukaemia, or CML. Treatment of CML usually relies on inhibitors of the abnormal protein that causes the condition but some patients do not respond to treatment and efforts are underway to develop a supplementary approach, targeting the so-called JAK2 kinase.
