DNA-protein cross-links (DPXs) in fish erythrocytes represent a potential biomarker for exposure to metal cations, such as hexavalent chromium (Cr[VI]) and divalent nickel (Ni[II]). Species-specific sensitivities to DPX formation were studied by coexposure of juvenile specimens of rainbow trout, hybrid bluegill, and channel catfish to waterborne metals, such as Cr(VI) and Ni(II). In a species c...

Guanine nucleotides, divalent cations, and sodium differentially regulate agonist and antagonist binding to adenosine A1 receptors in brain membranes. Guanine nucleotides decrease the binding of the adenosine A1 receptor agonist [3H]N6-cyclohexyladenosine ([3H]CHA) to guinea pig and bovine brain membranes by about 50% at 1--3 microM, while not affecting binding of the antagonist [3H]1,3-diethyl...

neospora caninum, an apicomplexan protozoan, is regarded as a major cause of abortion and stillbirth in cattle in countries world-wide. the ability to detection n.caninum in tissue samples can be a useful detection diagnostic tool for use in the study of the pathogenicity, immunoprophylaxis, and treatment of neospora infection. however, molecular biology is one of the most sensitive tools for d...

The study assessed the health quality of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) seed samples collected from formal and informal sector in Ethiopia and Syria. In Ethiopia, several seed-borne fungi were found on wheat samples: Cochliobolus sativum, Fusarium avenaceum, F. graminearum, F. nivale, F. poae and Septoria nodorum. C. sativum was predominant with 84% of samples...

INTRODUCTION Post-operative outcomes may be improved by the use of flow related end-points for intra-venous fluid and/or low dose inotropic therapy. The mechanisms underlying this benefit remain uncertain. The objective of this study was to assess the effects of stroke volume guided intra-venous fluid and low dose dopexamine on tissue microvascular flow and oxygenation and inflammatory markers ...

a simple special protocol using semichon’s acetic carmine stain was applied for examination of muscles of some small mammals, naturally infected with sarcocystis spp. using this method, infected muscles fibers with sarcocystis could easily be differentiated from muscle tissues. this method can be applied for screening of infected muscles with sarcocystis cysts on large number of samples for epi...

Salinity stress restricts growth of soybean plant [Glycine max (L.) Merr.]. Glycine betaine (GB) is among osmoprotectant compounds that are produced in tolerant plant species in response to environmental stresses. Soybean is sensitive to soil salinity and is classified as a low-ccumulator of glycine betaine. Therefore, this study was performed to evaluate the salinity tolerance of two contrasti...

INTRODUCTION The administration of dopexamine may constitute a therapeutical option to improve hepatosplanchnic perfusion in sepsis. In order to verify this hypothesis, we administered dopexamine in an experimental sepsis model in rats. METHODS This prospective, randomized, controlled laboratory study was conducted in 42 Wistar rats. The animals were divided into 3 groups. Group 1 (CON group)...

The purpose of our experiment was to investigate, if apparently healthy, vaccinated chickens may be involved in maintaining and spreading infectious bursal disease virus (IBDV) in poultry environments. We aimed at simultaneous detection and identification of very virulent field strain IBDV (vvIBDV) as well as vaccine strain IBDV in experimentally infected chickens. Two groups of specific pathog...
