Identifying symptom cluster in cancer patients undergoing chemotherapy-in Vietnam: A cross-sectional study.

Background: Major cancer treatments can cause a wide range of unpleasant symptoms that burden oncology patients. Different symptom clusters (SC) among cancer patients have been reported in the literature. This study determined the prevalence of symptoms patients experience during chemotherapy treatment and identified symptom clusters among them.

Reversible and size-selective opening of the inner Blood-Retina barrier: a novel therapeutic strategy.

The inner Blood-Retina-barrier (iBRB) remains a key element in retarding the development of novel therapeutics for the treatment of many ocular disorders. The iBRB contains tight-junctions (TJ's) which reduce the space between adjacent endothelial cells lining the fine capillaries of the retinal microvasculature to form a selective and regulatable barrier. We have recently shown that in mice, the iBRB can be transiently and size-selectively opened to molecules with molecular weights of up to approximately 1 kDa using an siRNA-mediated approach involving suppression of the tight junction protein, claudin-5.
