A potential chemotherapeutic drug to treat hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, particularly in China. However, HCC remains one of the more difficult cancers to treat. It is important to screen for new anti-cancer drugs. A number of dietary compounds possess anti-cancer properties. These dietary compounds may modify the activity of specific targets that control cell proliferation and apoptosis. Galangin could inhibit the methoxyresorufin O-demethylase activity of CYP1A2, CYP1A1 and P-form phenolsulfotransferase. Galangin induced apoptosis in several cancer cell lines and arrested the cell cycle, modulated the expression of cycline/cdk, and decreased Bcl-2. It was suggested that galangin may be a potential anti-tumor agent. However, the mechanism by which galangin exerts its anti-tumor activity is unknown.

Vanishing bile duct syndrome secondary to anti-retroviral therapy in HIV

Vanishing bile duct syndrome (VBDS) refers to a group of disorders characterized by destruction and disappearance of intrahepatic (inside the liver) bile ducts. Multiple causes have been identified including infections, malignancies, autoimmune conditions and adverse effects of medications. The usual course of this condition is variable and many patients with VBDS respond to treatment of the underlying condition and/ or removal of the offending agent. However, others progress to cirrhosis and end stage liver disease requiring liver transplantation.

Functional magnetic resonance imaging to evaluate pancreatic cancer

Pancreatic ductal adenocarcinoma (the disease commonly referred to as pancreatic cancer) carries the worst prognosis of any cancer. As current treatments offer minimal benefit, entirely new approaches are needed. Given the success of local therapies, as opposed to intravenous systemic therapies, for liver diseases (such as hepatocellular carcinoma), it is thought that similar local therapies may benefit patients with pancreatic cancer. To develop such therapies, it would be useful to devise targets that are easy to obtain and can indicate the efficacy of these new therapies in models of pancreatic cancer.

Brain potentials reveal spectator effect

The neurological responses caused by observing somebody else playing a game have been uncovered. Researchers writing in the open access journal BMC Neuroscience found differing responses for neutral observers, compared to those who wished the player to fail and those who wanted to see the player succeed.

A leap forward in addiction awareness and control

Funded by the Economic and Social Research Council (ESRC) the study designed the two programmes and examined their effectiveness in helping excessive drinkers reduce their drinking. The AACTP and LEAP programmes address the challenges faced by excessive drinkers, including a preoccupation with drinking made worse by alcohol-related stimuli around them. . The study also addressed excessive drinkers’ difficulties with motivation which prevent them focusing on and achieving goals which provide alternative healthy activities to drinking alcohol.
