Procalcitonin helps predict prognosis among those with peritonitis

Monitoring blood levels of a compound known as procalcitonin in patients with peritonitis (a serious intra-abdominal infection) could help identify patients at increased risk of organ failure and death, according to a report in the February issue of Archives of Surgery.

Cell pathway identified which plays critical role in colon cancer

For the one in 18 men and women who will be diagnosed with cancer of the colon and rectum during their lifetime and over 150,000 people diagnosed on a yearly basis, today's genetic research news offers some optimism.

California Appellate Court panel hears arguments in challenge of State proposition promoting embryonic stem cell research

A three-judge panel of the California Court of Appeal in San Francisco on Wednesday heard oral arguments in two consolidated cases challenging the constitutionality of California's Proposition 71 -- approved by voters in 2004 to provide $3 billion for human embryonic stem cell research -- the Los Angeles Times reports.

RNAi shows promise in gene therapy

Three years ago Mark Kay, MD, PhD, published the first results showing that a biological phenomenon called RNA interference could be an effective gene therapy technique. Since then he has used RNAi gene therapy to effectively shut down the viruses that cause hepatitis and HIV in mice.

Search for vaccine to prevent Chlamydia

It's the most common bacteria-related sexually transmitted disease in the United States, so researchers at The University of Texas at San Antonio's South Texas Center for Emerging Infectious Diseases (STCEID) and The University of Texas at San Antonio Health Science Center have partnered to discover a vaccine that will prevent Chlamydia.

More evidence that inflammation can fuel cancer

As evidence mounts that the body's normally protective inflammation response can drive some precancerous tissues to become fully malignant, UCSF scientists report discovering an apparent trigger to this potentially deadly process.

C-Reactive protein plays a direct role in the onset of hypertension

We have discovered that C-Reactive Protein (CRP) is not merely a marker of the risk of hypertension, it actually induces hypertension.

Direct connection between a nation's overall happiness and its citizens' blood pressure problems

Doctors have known for a long time that blood pressure is one measure of an individual's health. This research is the first to demonstrate that there a connection between nations' happiness and blood-pressure levels.

Cancer is a stem cell issue

There is an urgent reason to study stem cells: stem cells are at the heart of some, if not all, cancers. Mounting evidence implicates a clutch of rogue stem cells brandishing 'epigenetic' marks as the main culprits in cancer. Wiping out tumours for good, some biologists believe, depends on uprooting these wayward stem cells.

Epigenetics to shape stem cell future

Everyone hopes that one day stem cell-based regenerative medicine will help repair diseased tissue. Before then, it may be necessary to decipher the epigenetic signals that give stem cells their unique ability to self-renew and transform them into different cell types.

Enzyme important in fetal heart-cell failure - findings provide new targets for treatment

In almost all forms of heart failure, the heart begins to express genes that are normally only expressed in the fetal heart. Researchers have known for years that this fetal-gene reactivation happens, yet not what regulates it.
