In view of recent recognition of the existence of two Herpesvirus hominis (HVH) types with antigenic and biological differences, an electron microscopic study was undertaken of pocks produced on the choriallantoic membrane of embryonated eggs after infection with type 1 and type 2 HVH strains. Besides the typical morphological features of herpesvirus infection noted by several investigators, it...

− The current study aimed to assess some novel pharmacological activities of vanillin. Vanillin inhibited the chick chorioallantoic membrane (CAM) angiogenesis. Vanillin had anti-inflammatory activity using the acetic acid-induced permeability model in mice. Anti-nociceptive activity of vanillin was shown using the acetic acid-induced writhing test in mice. Vanillin inhibited production of nitr...

the focus of this study was antimicrobial membrane-activity of actinomycetes isolated from soils of iran. in this work, soil samples were collected from desert and farming zones of northern and central iran. a total number of 45 actinomycetes were isolated from the soil samples. in the primary screening performed to evaluate antimicrobial activity, isolated microorganisms were analyzed in terms...

Although it is well established that tumors can induce endothelial cell mitosis and angiogenesis leading to extensive neovascularization, little is known concerning the spectrum of normal cells or tissues that may have similar inductive capabilities. A variety of developmentally active tissues were tested: mouse embryonic organ rudiments, mouse and rabbit trophoblast and placenta, and blastemal...

structural steel sections are mainly used in beams and columns of building frames. iran national steel industrialgroup is among the oldest and largest producers of beams in iran. it has two beam production lines, namely line630 and line 650. in this study, the mechanical properties of manufactured beams in these production lines werecompared. based on the t-test results, the elongation is signi...

We studied calcium-triggered fusion of sea urchin egg secretory granules to test whether membrane bound fusion proteins are required in both fusing membranes. Using both light scattering assays and video microscopy, we found that native granules fused to granules that had been inactivated with either trypsin or N-ethylmaleimide. Granules also fused with liposomes prepared from lipids extracted ...
