in order to study seed hardening process in pomegranate, some of the relevant biochemical parameters were evaluated in fleshy part of arils or seeds in various soft and hard seeded pomegranate genotypes from the initial fruit set upto ripening stages. lignin was determined from the seeds and enzyme assays were performed on the flesh of arils. analysis of variance revealed significant difference...

exsheathing fluid (ef) and excretory-secretory products (es) of infective third-stage cultured larvae ofostertagia circumcincta were analysed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sdspage). five and seven predominant proteins were found in the ef and es products, respectively. immunoblotting by sheep pre-infection serum did not react with any of the ef and es proteins, b...

in order to evaluate the effect of different nitrogen application methods on yield and yield components of winter wheat, a field experiment with split plot arrangement in randomized completely blocks design with four replicates was conducted during 2006-07. basal dressing in three levels (with no basal dressing, strip and distributing nitrogen fertilizer) as main plot and top dressing in six le...

Syrian hamsters become anemic and exhibit delayed growth following oral infection with third-stage Ancylostoma ceylanicum hookworm larvae. Here we describe experiments designed to determine the feasibility of adult worm transfer (AWT) between hosts, a technique that would facilitate the specific study of bloodfeeding hookworms in vivo without prior exposure of the host to larva-specific antigen...

frost in early spring is one of the limiting factors in the production of grape. chemicals offer useful approach to reduce low temperature-induced damages. different concentrations of salicylic acid including: 0 (control), 0.5, 1 and 2 mm were sprayed twice on 10 year-old ‘bidaneh sefid’ grape vines at full bloom stage and changes in leaf soluble carbohydrates, proline and protein levels were m...

Oestrus ovis is an economically important parasite of small ruminants and a zoonotic parasite with many reports of ophthalmomyiasis in human from Iran and other countries. The aim of the peresent study was the isolation and identification of excretory-secretory (ES) and somatic (S) antigens of O. ovis second and third stage larvae (L2, L3) collected from Arabi sheep breeds located in southwest ...

Lagochilascariosis, a disease caused by Lagochilascaris minor, affects the neck, sinuses, tonsils, lungs, the sacral region, dental alveoli, eyeballs and the central nervous system of humans. A cycle of autoinfection may occur in human host tissues characterized by the presence of eggs, larvae and adult worms. This peculiarity of the cycle hinders therapy, since there are no drugs that exhibit ...

Heartworm prevention: Major factors of resistance First, heartworm preventives were designed and marketed at doses intended to prevent infection by killing third-stage and young fourth-stage larvae, not microfilariae. Thus, microfilariae may persist despite exposure to a macrocyclic lactone (ML); these drug-selected microfilariae can be transmitted between dogs by mosquitoes. This seems an unwi...
