Transcriptional activation is a key process required for long-term memory formation. Recently, the transcriptional coactivator CREB-binding protein (CBP) was shown to be critical for hippocampus-dependent long-term memory and hippocampal synaptic plasticity. As a coactivator with intrinsic histone acetyltransferase activity, CBP interacts with numerous transcription factors and contains multipl...
Compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. To calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. A new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...
Ultrahigh storage densities of up to 1 Tb/in. or more can be achieved by using local-probe techniques to write, read back, and erase data in very thin polymer films. The thermomechanical scanning-probe-based data-storage concept, internally dubbed millipede, combines ultrahigh density, small form factor, and high data rates. High data rates are achieved by parallel operation of large 2D array...
Prolonged cold storage of plasma may induce the conversion of plasma prorenin (inactive renin) to renin. This phenomenon is exaggerated in oral contraceptive (OC) users; the titer of Hageman factor (HF, Factor XII) in OC users is higher than in nonusers. The present study relates these observations. The increment in plasma renin activity (PRA) during cold storage, as measured by generation of a...
The knowledge of dielectric properties may hold a potential to develop a new technique for quality evaluation of milk. The dielectric properties of water-diluted cow’s milk with milk concentrations from 70% to 100% stored during 36 h storage at 22 C and 144 h at 5 C were measured at room temperature for frequencies ranging from 10 to 4500 MHz using open-ended coaxial-line probe technology, alon...
investigating downstream changes in bed load shape can be useful to detect watershedhydrological processes and it is very important to design hydraulic structures and to managecapacity of large storage dams, properly. regarding to doing of enforcement studies, thisresearch was conducted in qalesar river in upstream of chahardangeh watershed in mazandaranprovince. after recognition of the study ...
objective: human basic fibroblast growth factor (bfgf) plays an important role in cellular proliferation, embryonic development, and angiogenesis as well as in several signaling pathways of various cell types. bfgf is an essential growth factor for the maintenance of undifferentiated human embryonic stem cells (hescs) and human induced pluripotent stem cells (hipscs). materials and methods: in ...
