Previous studies demonstrated that in the murine model of Onchocerca volvulus keratitis, neutrophils and eosinophils are recruited into the cornea in a biphasic manner in response to intrastromal injection. To determine if CD4(+) T cells regulate migration of neutrophils and eosinophils into the cornea, CD4(+) cells were depleted using monoclonal antibody GK1.5 before intrastromal injection of ...

The infective stage of Haemonchus contortus, the third-stage larva, retains the secondstage larval cuticle. Exsheathment takes place in the rumen of the host (Somerville, 1954), under the influence of a number of factors, chiefly unionized carbonic acid and dissolved gaseous carbon dioxide (Rogers, 1960). The ensheathed larva survives desiccation, but, if caused to exsheathe by appropriate trea...

The dauer larva of the nematode Caenorhabditis elegans is a good model system for investigating the regulation of developmental fates by environmental cues. Here we show that SDF-9, a protein tyrosine phosphatase-like molecule, is involved in the regulation of dauer larva formation. The dauer larva of sdf-9 mutants is different from a normal dauer larva but resembles the dauer-like larva of daf...

Results Under basal conditions, the major prostaglandin released by human microvascular endothelial cells is PGI2. Exogenous PGI2 markedly attenuated the migration of isolated eosinophils through cell-free filters. This effect was prevented by the IP receptor antagonist Cay10441 and the adenylyl cyclase inhibitor SQ29548. Treatment of endothelial cells with diclofenac, a non-selective COX inhib...

The forkhead gene FH1 encodes a HNF-3beta protein required for gastrulation and development of chordate features in the ascidian tadpole larva. Although most ascidian species develop via a tadpole larva, the conventional larva has regressed into an anural (tailless) larva in some species. Molgula oculata (the tailed species) exhibits a tadpole larva with chordate features (a dorsal neural senso...

The preimaginal stages including egg, mature larva and pupa of Pseudaspidapion botanicum Alonso-Zarazaga & Wang, 2011 were described and figured, diagnostic characters of larva and pupa were discussed, and corresponding biological information was supplied. The nomenclature of frontal setae in the larva compared with curculionid weevils, the absence of the hypopharyngeal bracon in the larva, and...

background : the visceral larva migrans (vlm) is a syndrome observed in human infection with helminth larval eggs such as the toxocara spp. that usually infects dogs and cats. among the risk factors involved in the occurrence of vlm, partic­ularly importance of these animal populations, an investigation was carried out for the presence of toxocara spp. eggs in public parks in the city of urmia,...
