A new study has found that red meat consumption is associated with an increased risk of total, cardiovascular, and cancer mortality.

Sugar-sweetened drinks linked to increased risk of heart disease in men, study suggests

Posted: 12 Mar 2012 01:27 PM PDT

Men who drank one sugar-sweetened beverage a day had a 20 percent higher risk of heart disease compared to men who did not drink any sugar-sweetened drinks. Daily sugar-sweetened drink consumption was also linked to higher levels of harmful lipids in the blood and inflammation. Artificially sweetened beverages did not increase heart-disease risk in this study.

New research addresses how the human body controls gamma-herpesviruses, a class of viruses thought to cause a variety of cancers.

Correcting human mitochondrial mutations

Posted: 12 Mar 2012 12:26 PM PDT

Researchers have identified, for the first time, a generic way to correct mutations in human mitochondrial DNA by targeting corrective RNAs, a finding with implications for treating a host of mitochondrial diseases.

Scientists identify more than 500 genes that may cause pancreatic cancer

Posted: 12 Mar 2012 12:26 PM PDT

Scientists have identified more than 500 genes that may cause or contribute to the development of pancreatic cancer. This particularly deadly disease has a 1-in-20 survival rate after five years, largely because no effective genetic screening method exists for early detection.

New study examines stair-related injuries among children in the US

Posted: 12 Mar 2012 11:03 AM PDT

A new study found that from 1999 through 2008, more than 93,000 children younger than five years of age were treated in US emergency departments for stair-related injuries. On average, this equates to a child younger than five years of age being rushed to an emergency department for a stair-related injury every six minutes in the US.

Epstein Barr-like virus infects and may cause cancer in dogs

Posted: 12 Mar 2012 11:02 AM PDT

Best known for causing mononucleosis, or "the kissing disease," the Epstein Barr virus has also been implicated in more serious conditions, including Hodgkin's, non-Hodgkin's and Burkitt's lymphomas. Now a team of researchers has the first evidence that an Epstein Barr-like virus can infect and may also be responsible for causing lymphomas in man's best friend.

Spring break ritual could lead to brain damage

Every year, thousands of teens and young adults celebrate Spring Break by binge drinking large amounts of alcohol, a dangerous right-of-passage and one linked to possible brain damage later as adults.

Delay in surgery can cause irreparable meniscus tears in children with ACL injuries

Posted: 12 Mar 2012 10:51 AM PDT

For children aged 14 and under, delaying reconstructive surgery for anterior cruciate ligament (ACL) injuries may raise their risk of further injury. If surgery occurs later than 12 weeks after the injury, the injury may even be irreparable.

Pockets of high cervical cancer rates found in North Carolina, U.S.

Posted: 12 Mar 2012 08:41 AM PDT

A study of cervical cancer incidence and mortality in North Carolina has revealed areas where rates are unusually high.

'Two steps' ahead in cystic fibrosis research

Posted: 12 Mar 2012 08:41 AM PDT

Restoring normal function to the mutant gene product responsible for cystic fibrosis (CF) requires correcting two distinct structural defects, according to new research. This finding could point to more effective therapeutic strategies for CF in the future.

Beliefs about genes, God, can change health communication strategies

Posted: 12 Mar 2012 08:41 AM PDT

Beliefs about nature and nurture can affect how patients and their families respond to news about their diagnosis, according to health communication researchers.

Growing market for human organs exploits poor

Posted: 12 Mar 2012 08:40 AM PDT

An anthropologist who spent more than a year infiltrating the black market for human kidneys has published the first in-depth study describing the often horrific experiences of poor people who were victims of organ trafficking.

Potential role of parents' work exposures in autism risk examined: Possible link between some work exposures and risk for offspring

Posted: 12 Mar 2012 08:39 AM PDT

Could parental exposure to solvents at work be linked to autism spectrum disorder (ASD) in their children? According to an exploratory study, such exposures could play a role, but more research would be needed to confirm an association.

Circumcision may help protect against prostate cancer

Posted: 12 Mar 2012 07:21 AM PDT

A new analysis has found that circumcision before a male's first sexual intercourse may help protect against prostate cancer. The study suggests that circumcision can hinder infection and inflammation that may lead to this malignancy.

Powerful treatment provides effective relief for urinary incontinence, study suggests

Posted: 12 Mar 2012 07:19 AM PDT

The biggest study into the treatment of urinary incontinence with botulinum toxin (trade name Botox) has demonstrated that it is effective in treating overactive bladder (OAB) - a debilitating common condition which can affect up to 20% of people over the age of 40.

World's tallest man stops growing

Posted: 12 Mar 2012 07:14 AM PDT

The world's tallest man appears to have stopped growing following treatment at the University of Virginia Medical Center, earning the medical center a mention in the 2012 Guinness World Records.

Mechanism in cells that leads to inflammatory diseases discovered

Posted: 12 Mar 2012 07:14 AM PDT

Researchers have unlocked the mystery of how an inflammatory molecule is produced in the body, a discovery they say could lead to advances in the treatment of rheumatoid arthritis, Type 2 diabetes and numerous other chronic diseases that affect tens of millions of people.

Sending out an SOS: How telomeres incriminate cells that can't divide

Posted: 12 Mar 2012 07:14 AM PDT

The well-being of living cells requires specialized squads of proteins that maintain order. Degraders chew up worn-out proteins, recyclers wrap up damaged organelles, and-most importantly-DNA repair crews restitch anything that resembles a broken chromosome. If repair is impossible, the crew foreman calls in executioners to annihilate a cell. As unsavory as this last bunch sounds, failure to summon them is one aspect of what makes a cancer cell a cancer cell.

Promising new drug target for kidney disease

Posted: 11 Mar 2012 09:32 PM PDT

Researchers have identified a regulator protein that plays a crucial role in kidney fibrosis, a condition that leads to kidney failure. Finding this regulator provides a new therapeutic target for the millions of Americans affected by kidney failure.

Protein discovery could switch off cardiovascular disease

Posted: 11 Mar 2012 09:32 PM PDT

Scientists have discovered a protein inside blood vessels with an ability to protect the body from substances which cause cardiovascular disease.

Nanotube technology leading to new era of fast, lower-cost medical diagnostics

Posted: 09 Mar 2012 07:56 AM PST

Researchers have tapped into the extraordinary power of carbon "nanotubes" to increase the speed of biological sensors, a technology that might one day allow a doctor to routinely perform lab tests in minutes, speeding diagnosis and treatment while reducing costs. The new findings have almost tripled the speed of prototype nano-biosensors, and should find applications not only in medicine but in toxicology, environmental monitoring, new drug development and other fields.
