A survey of ectoparasite infestation in dogs in Tehran, Iran.
This survey was conducted to identify and estimate the frequencies of ectoparasites of dogs in Tehran, Iran. A total of 143 dogs attended at the Small Animal Hospital of the Veterinary School, the University of Tehran, were examined for the presence of ectoparasites and dermatological lesions. Ectoparasite specimens and blood samples were sent to parasitology and hematology laboratories, respec...
متن کاملStress response of brown pelican nestlings to ectoparasite infestation.
Measurement of corticosterone has become a useful tool for assessing the response of individuals to ecological stressors of interest. Enhanced corticosterone levels can promote survival of stressful events; however, in situations where a stressor persists and corticosterone levels remain elevated, the adrenocortical response can be detrimental. A potential ecological stressor for wild birds is ...
متن کاملMitochondrial Genetic Variation in Iranian Infertile Men with Varicocele
Objective Several recent studies have shown that mitochondrial DNA mutations lead to major disabilities and premature death in carriers. More than 150 mutations in human mitochondrial DNA (mtDNA) genes have been associated with a wide spectrum of disorders. Varicocele, one of the causes of infertility in men wherein abnormal inflexion and distension of veins of the pampiniform plexus is observe...
متن کاملCCL22 16C/A Genetic Variation is not Associated with Breast Carcinoma in Southern Iranian Population
Background: CCL22/MDC is a CC chemokine with a critical role in regulation of the immune balance in physiological condition. CCL22/CCR-4 ligation has been documented to participate in the migration of regulatory T (Treg) cells and Th2 lymphocytes to the site of breast tumors; circumstances that are known to be associated with poor prognosis. Objective: To investigate the association of a single...
متن کاملSoil Transmitted Helminthic Infestation in Children of Kashmir Valley
Worm infestation is a major problem in children from developing countries due to bad hygienic conditions. It produces nutritional deficiencies and anaemia in children when present in large numbers. The present study deals with the investigation of the frequency of intestinal helminth parasites in children of Kashmir valley in the age group of 4-15 years. 312 children were examined for different...
