What relates to the short-term effectiveness of biliary drainage?
A research team from Taiwan identified factors that were related to the short term effectiveness of percutaneous transhepatic biliary drainage in cholangiocarcinoma patients and evaluated the impact of palliative drainage on their survival. They found the short term effectiveness of percutaneous biliary drainage was related to patient's prothrombin time or the extent of tumor involvement. It, however, had no impact on survival.

Findings that should speed the development of drugs for Parkinson's disease
Australian scientists have significantly advanced our understanding of dopamine release from nerve cells, findings that should speed the development of more effective drugs for treating Parkinson's disease. People with Parkinson's disease suffer from muscle rigidity, tremor, a slowing of physical movement and, in extreme cases, a loss of physical movement. These primary symptoms are caused by the loss of dopamine producing nerve cells in the brain.

Is hepatic differentiation of embryonic stem cells induced by valproic acid and cytokines?
A research team from China developed a protocol for direct hepatic lineage differentiation from early developmental progenitors to a population of mature hepatocytes. Their study showed that hepatic cells of different developmental stages from early progenitors to matured hepatocytes can be acquired in the appropriate order based on sequential induction with valproic acid and cytokines.

New culprit for viral infections among elderly -- an overactive immune response
Researchers at Yale School of Medicine have found that exaggerated responses of the immune system explain why the elderly succumb to viral infections more readily than younger people. Published in the Nov. 19 Cell Host & Microbe, the study bucks the general belief that declining immune responses are to blame for susceptibility to viral infections.

Oceans' uptake of manmade carbon may be slowing
The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions -- a finding with potentially wide implications for future climate. The study appears in this week's issue of the journal Nature.

Common pain relief medication may encourage cancer growth
Although morphine has been the gold-standard treatment for postoperative and chronic cancer pain for two centuries, a growing body of evidence is showing that opiate-based painkillers can stimulate the growth and spread of cancer cells. Two new studies advance that argument and demonstrate how shielding lung cancer cells from opiates reduces cell proliferation, invasion and migration in both cell-culture and mouse models.
