the effects of cholecystokinin (cck) receptor antagonists on hypothermia induced by cocaine or morphine have been studied in mice. in the present work, subcutaneous (sc) injection of cocaine (50-150 mg/kg) or morphine (125-500 mg/kg) induced hypothermia in mice. administration of ccka receptor antagonist mk-329 (0.5-1.5 mg/kg), cckb receptor antagonist l-365, 260 (0.5-1.5 mgl kg) and cck recept...

as the data on the epidemiology and outcome of fungal infections in children with hematologic cancer are limited especially in iran, this study was aimed to delineate the epidemiologic features and outcome of fungal infections in this population. the medical records of all children with hematologic malignancies diagnosed with a fungal infection from 2005 to 2010 at a tertiary pediatric hospital...

Differences between endophytic and ectophytic bacterial communities with stress on antagonistic bacteria, were studied by comparing the composition of communities isolated from the rhizosphere, phyllosphere, endorhiza and endosphere of field-grown potato plants using a multiphasic approach. Terminal restriction fragment length polymorphism analysis of 16S rDNA of the bacterial communities revea...

Mycoparasitic species of the fungal genus Trichoderma are potent antagonists able to combat plant pathogenic fungi by direct parasitism. An essential step in this mycoparasitic fungus-fungus interaction is the detection of the fungal host followed by activation of molecular weapons in the mycoparasite by host-derived signals. The Trichoderma atroviride MAP kinase Tmk1, a homolog of yeast Fus3/K...

Macrophomina phaseolina (Tassi) Goid is a destructive pathogen of cowpea that causes serious charcoal rot disease with significant yield losses. Antifungal activity of three indigenous Ascomycetes viz., Trichoderma harzianum, T. viride, and T. hamatum, and two Meliaceae members, i.e., Melia azedarach L. and Azadirachta indica L. were assessed against the pathogen. Laboratory screening trials wi...

Biting midges are globally distributed pests causing significant economic losses and transmitting arbovirus diseases to both animals and humans. Current biological and chemical control strategies for biting midge target destruction of adult forms, but strategies directed at immature stages of the insect have yet to be explored in Australia. In the present study, coastal waters of Hervey Bay reg...

The basidiomycete fungus Crinipellis perniciosa (Stahel) Singer is the causal agent of Witches' Broom Disease of Cacao (Theobromacacao L.) which is the main factor limiting cacao production in the Americas. Pod losses of up to 90% are experienced in affected areas as evidenced by the 50% drop in production in Bahia province, Brazil following the arrival of the C. perniciosa in the area in 1989....

The bacterial genus Burkholderia is abundant in the sugarcane rhizosphere. Literature states that some Burkholderia strains are nematode and fungal antagonists and/or plant growth promoters. Research was undertaken to obtain indigenous sugarcane-associated Burkholderia strains that possess these properties. Preliminary screening produced 13 isolates that are able to paralyse juveniles of Meloid...

Sulfonate sphingoids or sulfonolipids are bioactive unusual compounds found in members of the Bacteroidetes family. The present report describes the structures of sulfonolipids of halophilic bacteria, sharing structural similarity with compounds of fungal origin inhibiting the serine palmitoyl transferase and with capnines, known as antagonists of von Willebrandt factor. Two sulfonolipids (SL1 ...
