ABSTRACT- Almost all oyster mushroom producers in Iran produce this kind of mushroom without any kind of casing soil. Although different kinds of casing soils are available for Agaricus bisporus, limited information is available regarding Pleurotus ostreatus. Availability of peat in many regions around the world is a concern and some researchers' efforts have been devoted to a search for altern...

Intraventricular injections of vasopressin (VP) and antagonists with varying degrees of specificity for the VP receptors were used to identify the action of endogenous brain VP on 0.3 M NaCl intake by sodium-deficient rats. Lateral ventricular injections of 100 ng and 1 microg VP caused barrel rotations and a dramatic decrease in NaCl intake by sodium-deficient rats and suppressed sucrose intak...

The aim of this study was to investigate the relationship between recurrent miscarriages and factor V Leiden, prothrombin G20210A and C677T methylenetetrahydrofolate reductase (MTHFR) mutations. In this case-control study the prevalence of factor V Leiden, prothrombin G20210A and C677T methylenetetrahydrofolate reductase mutations was determined in a consecutive series of 80 recurrent miscarria...

In order to evaluate the direct-method test of sensitivity to drugs used in the principal tuberculosis treatment regimes, in the Organon Teknika MB/BacT system, we tested 50 sputum samples positive to microscopy taken from patients with pulmonary tuberculosis and with clinical indications for an antibiogram, admitted sequentially for examination during the routine of the reference laboratory. T...

Unique room temperature-formed iron-doped nickel hydroxide on Ni foam as a 3D electrode in alkaline electrolyte offers fast gas dissipation, a high number of active sites and a high oxidation state of Ni for an improved oxidation ability for the oxygen evolution reaction (OER), which delivers an OER current density of 100 mA cm-2 at an overpotential of 0.312 V and 96.3% retention after 100 h at...

The aim of this study was to investigate modulation of voltage-dependent steady-state activation and availability from inactivation of the cardiac Na+ channel by the cytoskeleton. As an experimental approach, we used long-lasting monitoring [63 ± 5 (SE) min] of the half-point potentials of the steady-state availability curve ( V 1/2A ) and normalized conductance curve ( V 1/2G) in 116 rat ventr...

A rapid, isocratic method for separating the most prevalent phospholipids by high-performance liquid chromatography is described. Baseline resolution of phosphatidylinositol, phosphatidylserine, phosphatidylethanolamine, phosphatidylcholine, lysophosphatidylcholine, and sphingomyelin is achieved in less than 40 min on a silica column. Lipids are injected in 10 microliter of chloroform-diethyl e...

The major envelope glycoprotein genes (ORF5) of seven Czech isolates of porcine reproductive and respiratory syndrome virus (PRRSV) were amplified and their nucleotide sequences were determined. ORF5 displayed nucleotide and amino acid identities of 87.5-100% and 87. 6-100%, respectively, among the isolates. In a phylogenetic tree, all European isolates were grouped in a genotype distinct from ...
