Polycythemia vera (PV) is a clonal disorder arising in multipotent hematopoietic progenitor cells. It causes the overproduction of red cells and, to a lesser extent, neutrophils and platelets. PV occurs with a slight predominance in men, and the median age of diagnosis is 60 years [1]. Although the association between PV and coronary artery disease is unknown, previous studies have reported cor...

The paper presents common mode voltage analysis of single phase grid connected photovoltaic inverter. Many researchers proposed different grid tie inverters for applications like domestic powering, street lighting, water pumping, cooling and heating applications. Traditional grid tie PV inverter uses either a line frequency or a high frequency transformer between the inverter and grid. The tran...

Scientists have observed local field potential theta rhythms (3-12 Hz) in the hippocampus for decades, but understanding the mechanisms underlying their generation is complicated by their diversity in pharmacological and frequency profiles. In addition, interactions with other brain structures and oscillatory drives to the hippocampus during distinct brain states has made it difficult to identi...

Polycythemia vera (PV) is a clonal hematologic disease characterized by hyperplasia of the three major bone marrow lineages. PV erythroid progenitor cells display hypersensitivity to several growth factors, which might be caused by an abnormality of tyrosine phosphorylation. In the present study, we have investigated protein tyrosine phosphatase (PTP) activity in highly purified erythroid proge...

In the lateral hypothalamus, groups of functionally related cells tend to be widely scattered rather than confined to discrete, anatomically distinct units. However, by using parvalbumin (PV)-specific antibodies, a solitary, compact cord of PV-immunoreactive cells (the PV1-nucleus) has been identified in the ventrolateral tuberal hypothalamus in various species. Here we describe the topography,...

A high-sucrose diet (SU) decreases insulin action in the liver (Pagliassotti MJ, Shahrokhi KA, and Moscarello M. Am J Physiol Regulatory Integrative Comp Physiol 266: R1637-R1644, 1994). The present study was conducted to characterize the effect of SU on glucagon action in isolated periportal (PP) and perivenous (PV) hepatocytes by measuring glucagon-stimulated glycogenolysis and glucose releas...

Cholecystokinin (CCK)- and parvalbumin (PV)-expressing neurons constitute the two major populations of perisomatic GABAergic neurons in the cortex and the hippocampus. As CCK- and PV-GABA neurons differ in an array of morphological, biochemical and electrophysiological features, it has been proposed that they form distinct inhibitory ensembles which differentially contribute to network oscillat...

A solar trigeneration system for off-grid households, based on photovoltaic-thermal (PV/T) collectors, photovoltaic (PV) modules and a heat pump (HP), whose aim is to provide enough electricity, domestic hot water (DHW), heating and cooling power to meet the typical demand of an offgrid single family dwelling, is modeled to predict its performance, enable system sizing and evaluate the impact o...

The reality bites for ‘green energy’ when the economic assessment shows it as not a viable investment. Economic assessment for projects normally uses Return on Investment (ROI), Payback Period (PBP), Life Cycle Assessment (LCA), Life Cycle Cost (LCC) and Cost Benefit Analysis (CBA). Several studies have argued against these tools; but they are common due to lack of alternatives. To demonstrate ...

There are various methods that can be employed to increase the lifespan and power output of photovoltaic (PV) systems. This study aims a grid-connected PV system by using water-cooling unit solar reflectors. The modules current divided into two clusters. first cluster, which is considered an improved has reflector-cooling added it, while second cluster used as reference. results show maximum ef...
