The effects of three molecular weight ranges of dextran sulfate on five different human immunodeficiency virus (HIV) isolates (from patients with acquired immunodeficiency syndrome), alone and in combination with dideoxynucleosides, were investigated in vitro. The higher the molecular weight range of dextran sulfate, the more potent the activity as assessed by a quantitative syncytium formation...

Among the two types of bacterial L-asparaginases, only type II enzymes have been used inthe treatment of acute lymphoblastic leukemia owing to their higher affinity for L-asparagine.However, current screening media used for the isolation of L-asparaginase-producingmicroorganisms do not discriminate between the two types of L-asparaginase. During anoptimization study conducted to increase L-aspa...

Background & Objective: Traditional medicines have a wide range of pharmacological properties. This work was aimed to investigate the antimicrobial effect of Thymus vulgaris, Matricaria chamomilla, Melissa officinalis and Rhus coriaria extracts against clinical isolates of Pseudomonas aeruginosa. Materials and Methods: 180 P. aeruginosa clinical isolates were examined. disc diffusion method as...

Bioassays are currently used to measure the presence of functionally active cytokines in biological fluids. These assays may be influenced by the presence of other substances, either cytokine specific or not, in such fluids. In the present study, we analyzed whether some currently used disease-modifying antirheumatic drugs (DMARDs) could interfere with the measurements of circulating interleuki...

Background: Some studies identified the health effects of COVID-19 disease, but they are not sufficient to control it. This study was designed to recommend some possible useful acts in daily life to protect people against COVID-19) based on the various effects of the disease on human life, which have been proven in previous studies. Method: Google Scholar, PubMed, and World Health Organization...

citrus blast disease caused by pseudomonas spp is among the most injurious diseases of citrus. in the northern citrus growing provinces of iran. to determine the species and pathovars of pseudomonas strains associated with the disease in mazandaran province and in the neighboring areas in guilan and golestan provinces and as well to assess their phenotypic heterogeneity and virulence, symptomat...

soybean, glycine max (l.) merr is one of the most important oilseed plants in the world and phythophthora root and crown rot is a significant limiting factor for its planting. in the present study the antagonistic effect of 12 trichoderma spp. in vitro and these trichoderma spp. in combination with bradyrhizobium japonicum in vivo on phytophthora sojae and soybean growth were tested. in laborat...

Four patterns of inositol fermentation by different isolates of Klebsiellae are described. Inositol fermentation by some isolates may be modified by medium incorporation of acetoin and diacetyl. An inositol--hydrogen sulphide--motility medium, modified by reducing the pH value, increasing the inositol concentration, and the incorporation of acetoin, is described and evaluated as a means of dete...
