Red meat consumption linked to increased risk of total, cardiovascular, and cancer mortality Posted: 12 Mar 2012 01:27 PM PDT 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.

How the human body controls viruses thought to cause a variety of cancers Posted: 12 Mar 2012 12:28 PM PDT New research addresses how the human body controls gamma-herpesviruses, a class of viruses thought to cause a variety of cancers.

Tweens just say 'maybe' to cigarettes and alcohol Posted: 12 Mar 2012 12:28 PM PDT When it comes to prevention of substance use in our tween population, turning our kids on to thought control may just be the answer to getting them to say no.

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.

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.

'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.

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.

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.

Reducing academic pressure may help children succeed Posted: 12 Mar 2012 07:14 AM PDT Children may perform better in school and feel more confident about themselves if they are told that failure is a normal part of learning, rather than being pressured to succeed at all costs, according to new research.

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.
