background calcium infusion is used as a pre-treatment before calcium channel blockers to prevent hypotension. occasional cardioversion with calcium gluconate infusion is seen in patients with paroxysmal supraventricular tachycardia. several mechanisms have been suggested for mechanism. herein we report a case presenting with atrial fibrillation but cardioverted with calcium gluconate infusion,...

One of the many challenging tasks of protein design is the introduction of a completely new function into an existing protein scaffold. In this study, we introduce a new computational procedure OptGraft for placing a novel binding pocket onto a protein structure so as its geometry is minimally perturbed. This is accomplished by introducing a two-level procedure where we first identify where are...

summer pruning and calcium spray could improve kiwifruits quality. in this study, effect of summer pruning in two times, 2 and 15 days after petal fall alone or in combination with %1 calcium chloride spray on fruit quality and mineral elements contents of ‘hayward’ kiwifruit was investigated. calcium sprayed four times 90 days after petal fall with 15 days intervals. the results showed that su...

Bupropion is an atypical antidepressant drug. Fluctuating in its serum levels following oral administration of immediate release dosage forms leads to occasional seizure. The aim of the present work was designing of sustained release bupropion HCl nanospheres suited for pulmonary delivery. Agar nanospheres were prepared by transferring the w/o emulsion to solid in oil (s/o) suspension. Calcium ...

Water hyacinth ( Eichhornia crassipes ) is one of the potential feedstocks for bioethanol production due to their higher cellulose content. It needs optimization pretreatment remove lignin and release hemicellulose from lignocellulosic complex. Pretreatment was done using sulfuric acid, sodium hydroxide, calcium hypochlorite as soaking agents. Experiment carried out at 121 °C 15 minutes. with 1...

Calcium imaging data promises to transform the field of neuroscience by making it possible to record from large populations of neurons simultaneously. However, determining the exact moment in time at which a neuron spikes, from a calcium imaging data set, amounts to a non-trivial deconvolution problem which is of critical importance for downstream analyses. While a number of formulations have b...

in recent years, due to absence of integrated watershed management in most regions, natural resources have witnessed numerous damages with severe floods as one of its consequences which further leads to economic, social and environmental damages. presently, there is no optimal utilization of land in most watersheds hence no optimal model matching with facilities and objectives is used in the wa...

calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. in this study, various formulations of calcium acetate tablets were prepared and their disintegrati...

Hyperphosphatemia has an important role in the development of secondary hyperparathyroidism and bone disease in patients with end-stage renal disease (ESRD). The most effective method of phosphate elimination lies with phosphate binders, the agent that more commonly used, calcium carbonate, is not an ideal binding agent. In this regard, calcium acetate has been reported to have more or at least...

The potential of membrane scaling control by a real-time optimization algorithm was investigated. effect antiscalant dosing evaluated from the induction time measured in glass batch-reactors, and operational performance lab-scale reverse osmosis (RO) unit two pilot-scale RO units. Step changes demonstrated that accumulation is ‘paused’ during periods when optimum dose applied. This paramount fo...
