Na+ efflux across basolateral membranes of isolated epithelia of frog skin was tested for voltage sensitivity. The intracellular Na+ transport pool was loaded with 24Na from the apical solution and the rate of isotope appearance in the basolateral solution (JNa23) was measured at timed intervals of 30 s. Basolateral membrane voltage was depolarized by either 50 mM K+, 5 mM Ba++, or 80 mM NH+4. ...

Magnetized water showed alterations in the electrolyte potential and vibration modes. This study aimed to investigate the effect of magnetic water and physiological solutions on the UV-spectra of tramadol HCl. Distilled water as well as full strength or diluted physiological solutions are magnetized by magnetic disc. Then tramadol HCl was dissolved in each magnetic and in non-magnetic solution ...

In this work the acidity constants of Thiamine in water and water-Triton X-100 micelle media solutions, at 25 °C, have been determined spectrophotometrically. To evaluate the pH- absorbance data, a resolution based on the combination of soft-and hard-modeling is applied. The acidity constants of all related equilibria are estimated using the whole spectral fitting of the collected data to a...

This experiment was conducted to determine the effect of foliar spray with polyamines on postharvest life of chrysanthemum cut flowers in the horticulture laboratory of Islamic Azad University of Rafsanjan in 2015. For this purpose, an experiment was conducted based on a completely randomized design with three replications with spermidine, spermine and putrescine treatments at 1, 2 and 3 mM con...

CLINICAL CHEMISTRY, Vol. 33, No. 1, 1987 189 tubes containing 200 ML of 0.6 mol/L HC1O4; thus deproteinization was instantaneous. The tubes were centrifuged within 1 h and the clear protein-free supernate was stored at 4 #{176}C until assayed. Such deproteinized samples were stable for at least two months at 4 #{176}C and were analyzed without prior neutralization. Lactate was measured with an ...

In two party privacy preserving association rule mining, the issue to securely compare two integers is considered as the bottle neck to achieve maximum privacy. Recently proposed fully homomorphic encryption (FHE) scheme by Dijk et.al. can be applied in secure computation. Kaosar, Paulet and Yi have applied it in preserving privacy in two-party association rule mining, but its performance is no...

Preparation and crystallization G6-amylase from alkalophilic Bacillus sp.707 was expressed by Bacillus subtilis 207-25. The enzyme was crystallized by the hanging drop vapor diffusion method using the reservoir solution containing 50% (v/v) 2methylpentane-2, 4-diol, 100 mM Tris-HCl (pH 8.5) and 200 mM ammonium phosphate. Calcium chloride and sodium chloride were added to final 1 mM in the drop ...
