Objective(s): Erythropoiesis is regulated by some extrinsic and intrinsic factors as microRNAs (miRNAs). miRNAs are endogenously small non-coding regulatory RNAs which play vital roles in the variety of cellular fate, critical processes; growth, apoptosis, metabolism, survival of the cells and specially differentiation. Several miRNAs such as miR-16 and miR-451 have been shown to be correlate...

Memory is a way of connecting people with their pasts. Historical buildings, museums, archives and monuments are some the tools which help to remember pasts (Nora, 1989). Books also have perspective about communal past. However, these things lose meaning in dystopian society like one portrayed Fahrenheit 451. Memories turn into weapons that destruct threaten human happiness foundations society....

During Leg 59 of the Deep Sea Drilling Project, five sites (447 to 451) were occupied and seven holes drilled between Okinawa and Guam in the Philippine Sea (Fig. 1). All holes except Hole 447 yielded common calcareous nannoplankton at certain intervals cored. Nannoplankton assemblages and their age assignments will be discussed for each site, and fossil lists for selected samples from Holes 44...

The adaptation of cancer cells to the constantly changing conditions of their microenvironment during tumor progression requires dynamic and flexible mechanisms. Glioblastoma and other tumors cells require a continuous flux of nutrients and oxygen to sustain growth and elevated metabolism; yet, there is often insufficient supply of blood and energy to nourish this growth/metabolism. While the a...
