Throughout the world, millions of Muslims fast daily during the month of Ramadan from sunrise (Sahar) until sunset (Iftar). Considering the impacts of environment on physiological functions, we performed this study in order to examine the effects of Ramadan fasting on some blood parameters of healthy volunteers and hypertensive patients. According to the results, there were no significant chang...

Investigation of aluminium uptake by human erythrocytes was the major aim of this study. Packed red blood cells were incubated in Earle's medium (pH 7.4) containing varying concentrations of aluminium (0-160 /lg/J) as AIK(SO.), and aluminium content of the cells were determined using flameless atomic absorption. There was significant increase in aluminium content of the cells. Addition of 5...

For building a sustainable fermentation process, it is essential to reduce dependence on natural resources and lower the amount of pollution that created. The reuse agro-industrial wastewater after possible treatment leads achievement these goals concurrently. This study investigates production citric acid cellulase enzyme by A. niger cultivated in olive mill (OMW) using loofa sponge-packed col...

A method is described whereby the packed cell volume (PCV) of a blood sample can be estimated from the haemoglobin concentration. The method defines the relation existing between haemoglobin concentration and the PCV of blood samples and uses the mathematical formula thus obtained to estimate an unknown PCV value for a sample by extrapolation from the known haemoglobin value of the same sample....

Lacunar (small deep cerebral infarcts) infarction is described in association with raised packed cell volumes. Two patients had polycythaemia vera, one stress polycythaemia. They presented with transient ischaemic episodes and were shown by computed tomography to have lacunes deep in the basal ganglia and internal capsule. Such lesions may be caused by small vessel occlusions related to increas...

During the purification of an aquarium for carp breeding, a relatively high level of chemical oxygen demand (COD) was removed by filtration systems packed with both alginate- and polyvinyl alcohol (PVA)-immobilized gel beads of Rhodobacter sphaeroides S. Low nitrate accumulation was observed in the alginate gel beads packed system due to denitrification, but high levels of nitrate and nitrite a...

Most healthy humans have a haemoglobin concentration of 12 to 15 g/dL and most intensivists now transfuse packed red blood cells for haemoglobin <7 g/dL. Higher haemoglobin is associated with improved intermediate and clinical outcomes after subarachnoid hemorrhage (from ruptured brain aneurysm) or neurotrauma. An observational study in a recent issue shows that higher haemoglobin was associate...

Morphogenesis is driven by small cell shape changes that modulate tissue organization. Apical surfaces of proliferating epithelial sheets have been particularly well studied. Currently, it is accepted that a stereotyped distribution of cellular polygons is conserved in proliferating tissues among metazoans. In this work, we challenge these previous findings showing that diverse natural packed t...

A proportional-resonant (PR)-based current control strategy for grid-connected packed-E cell (PEC) inverter is presented. Unlike the existing strategies, which are based on proportional-integral controller, developed packed-U and PEC inverters, proposed PR-based achieves zero steady-state error in grid current. Furthermore, it eliminates necessity of employing loop regulating dc capacitor volta...
