Effect of surgically-induced weight loss on inflammatory mediators and peripheral blood monocyte CD11b expression in morbid obesity.

Obesity is characterized by a state of chronic mild inflammation, with raised circulating levels of inflammatory markers. Expression and release of inflammation-related adipokines, generally, rise as adipose tissue expands. In the present study we evaluated the level of serum mediators concerned in inflammation and monocyte activation (TNF-alpha, hs-CRP, MCP-1) together with percentage of CD11-b expression on monocytes in a group of morbidly obese individuals (n = 20) before and (3-6 months) after restrictive surgery, and in 15 healthy normal weight individuals.

The prognostic potential of bone marrow cyclin E and P27, in Egyptian patients with acute myeloid leukemia.

Cyclin E and the cyclin dependent kinase inhibitor P27 are two important regulators of the G1-S transition modulating the activity of cyclin-dependent kinases. Aberrations in the cell cycle control are often observed in tumors and might even be mandatory in tumor development. There are few molecular biologic determinants that may be prognostic for patients with acute myeloid leukemia (AML).
