Imaging agents offer new view of inflammation, cancer

Posted: 07 Oct 2011 10:23 AM PDT

A series of novel imaging agents could make it possible to "see" tumors in their earliest stages, before they turn deadly. The compounds, derived from inhibitors of the enzyme cyclooxygenase-2 and detectable by positron emission tomography imaging, may have broad applications for cancer detection, diagnosis and treatment.

New targets for treating inflammatory, autoimmune diseases discovered

Posted: 07 Oct 2011 09:25 AM PDT

Researchers have discovered a cellular pathway that promotes inflammation in diseases like asthma, rheumatoid arthritis, psoriasis, inflammatory bowel disease, and multiple sclerosis. Understanding the details of this pathway may provide opportunities for tailored treatments of inflammatory and autoimmune diseases.

Jonesing for java: Could caffeine use predict risk for cocaine abuse?

Posted: 07 Oct 2011 08:39 AM PDT

Genetic link to suicidal behavior confirmed

Posted: 07 Oct 2011 08:39 AM PDT

A new study has found evidence that a specific gene is linked to suicidal behavior, adding to our knowledge of the many complex causes of suicide. This research may help doctors one day target the gene in prevention efforts.

Why anti-rejection drugs for organ transplant patients cause hypertension

Posted: 07 Oct 2011 07:33 AM PDT

A group of researchers has discovered the process that may be causing side effects caused by the anti-rejection drugs given to organ transplant patients. The discovery means those side effects likely can be dealt with much more cheaply and easily.

Study tracks mutations causing congenital dyserythropoietic anemia (CDA) II back to the Roman Empire

Posted: 07 Oct 2011 07:32 AM PDT

A new study analyzed two mutations (E109K and R14W) of the SEC23B gene and discovered one of them is responsible for the higher frequency of CDA II in Italian population. The first mutation, E109K, may have originated in the Middle East about 2.400 years ago and may have spread in the heyday of the Roman Empire. The other one may have originated in Southern Italy about 3.000 years ago.

Raising 'good' cholesterol levels reduces heart attack and stroke risk in diabetes patients

Posted: 07 Oct 2011 07:32 AM PDT

Increasing levels of high-density lipoproteins, better known as HDL or "good" cholesterol, reduced the risk for heart attack and stroke among patients with diabetes.

Timing is crucial for family consent in brain dead organ donors

Posted: 07 Oct 2011 04:32 AM PDT

Hearts used in transplants can only be sourced from donors that are brain dead before circulation to their heart has ceased. Data from a new study indicate that the time at which organ donation in brain dead donors is first discussed with family members could affect whether or not they consent to donation.

Pregnant mothers at risk from air pollution, California study suggests

Posted: 07 Oct 2011 04:32 AM PDT

A California-based study has looked in detail at air quality and the impact of traffic-related air pollution on premature birth. Results from the study show that traffic-related air pollution, especially polycyclic aromatic hydrocarbons, is associated with up to a 30 percent increase in premature births, and that seasonal changes and vicinity to the coast affected concentration of toxic pollutants in the air.
