Hybrid nanoprobe specifically designed to use as a contrast agent targeting phagocytic cells in an animal model of ischemic stroke and imaging using MRI, intravital two-photon microscopy phase X-rays imaging.

Chicken peritoneal exudate cells (PEC) were induced by Sephadex G-50 injection and were used for studying their in vitro phagocytic activity towards sheep red blood cells (SRBC) and Salmonella gallinarum. The peritoneal macrophages-were phagocytic to opsonised as well as to non-opsonised SRBC or S. gallinarum. The recognition and phagocytosis depended on time of exposure as well as the intensit...

This study aims to examine the efficacy of oral whole-cell vaccine S. agalactiae with Artemia sp as a vector for prevention against Streptococcosis in tilapia fish. The fish seeds used were 2-3 cm size which did not carry bacteria and reared jars volume 3 liters many ten birds/jar. Giving orally by first soaking sp. times 15, 30, 60, 90, 120 150 minutes. Parameters observed relative percent sur...

Aim of the study: To evaluate hemato-immunological parameters in Palomino trout compared to naturally pigmented rainbow trout.
 Area Fars province (SW Iran).
 Material and methods: Sixty fish both varieties (30 30 pigmented) were sampled from same pond. After blood sampling, hematological parameters, total serum protein immunoglobulin (Ig), phagocytic activity, respiratory burst lysoz...

Phagocytic vesicles from rabbit lung macrophages produced superoxide in the presence of NADH or NADPH. At 37 degrees C, these vesicles generated 51+/-7.8 nmol O(2) (-)/min per mg protein in the presence of 0.5 mM NADPH. The apparent K(m) for NADPH and NADH (66 and 266 muM, respectively), the pH optimum for the reaction (6.9), and the cyanide insensitivity were similar to properties of plasma me...

Phagocytosis is the process by which cells internalize particulate material, and is of central importance to immunity, homeostasis and development. Here, we study the internalization of immunoglobulin G-coated particles in cells transfected with Fcgamma receptors (FcgammaRs) through the formation of an enveloping phagocytic cup. Using confocal microscopy, we precisely track the location of fluo...

BACKGROUND Trypanosoma cruzi is an intracellular parasite that, like some other intracellular pathogens, targets specific proteins of the host cell vesicular transport machinery, leading to a modulation of host cell processes that results in the generation of unique phagosomes. In mammalian cells, several molecules have been identified that selectively regulate the formation of endocytic transp...

The study was focused on the observation of alkaline and acidic phosphatase activity in the glandular cells of the uterine endometrium in puerperal moufflon ewes (Ovis musimon) after exposure to polychlorinated biphenyls. Fifteen animals divided into 2 groups (experimental group – n=8; control group – n=7) were included in the experiment. The immunotoxic effect was evaluated by the test of the ...

Purpose: To investigate in vivo immunomodulatoryeffect and histopathological feature of mouse liver and kidney following treatment with 2 neolignans (Pc-1 and Pc-2) isolated from red betel (Piper crocatum Ruiz & Pav) leaf. Methods: Balb/c mice immune response was induced with Listeria monocytogenes. Immunomodulatory effect was tested by using macrophage phagocytic, nitric oxide, and lymphocyte ...
