Pomegranate juice and punicalagin-mediated chemoprevention of hepatocellular carcinogenesis via regulating miR-21 and NF-κB-p65 in a rat model.

Background: Hepatocellular carcinoma (HCC) is the most common neoplasm among primary liver malignancies, accounting for 70%-85% of total liver cancer cases worldwide. It is also the second-leading cause of cancer-related death worldwide. Recent research has investigated naturally occurring products high in polyphenolic compounds in the regression and prevention of HCC.

Effects of pomegranate aril juice and its punicalagin on some key regulators of insulin resistance and oxidative liver injury in streptozotocin-nicotinamide type 2 diabetic rats.

Nowadays, medicinal plants have been widely used everywhere to provide essential care for many disorders including diabetes. Recent reports assumed that the antidiabetic activities of pomegranate aril juice (PAJ) may be ascribed to its punicalagin (PCG). Therefore, the present study evaluated and compared the antidiabetic activities of PAJ and its PCG, and monitored some mechanisms of their actions in streptozotocin-nicotinamide (STZ-NA) type 2 diabetic rats.

On asphericity of convex bodies in linear normed spaces.

In 1960, Dvoretzky proved that in any infinite dimensional Banach space and for any [Formula: see text] there exists a subspace of of arbitrary large dimension -iometric to Euclidean space. A main tool in proving this deep result was some results concerning asphericity of convex bodies. In this work, we introduce a simple technique and rigorous formulas to facilitate calculating the asphericity for each set that has a nonempty boundary set with respect to the flat space generated by it.
