Parasitic infection caused by helminths and protozoa are the major cause of human disease in most countries of tropical region. It is estimated that about 3.5 billion people are infected with intestinal parasites of whom 450 million are ill. The prevalence of intestinal parasitic infection varies not only geographically but also in different region in the same country. The present study is unde...
Background & Aims: Cryptosporidiosis is one of the most important parasitic zoonoses of human and animals. This infection is common in mammals and caused by the coccidian parasites of the genus Cryptosporidium. The Present study was designed to determine the epidemiology of Cryptosporidium infection in cattle in Kerman by using conventional morphological as well as molecular methods for molecul...
in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...
ABSTRACT Cryptosporidium spp. are zoonotic protozoa, frequently associated with diarrhea in calves, which responsible for important economic losses. The aim of this study was to assess the prevalence infection by and its risk factors among calves raised a milk production region Northeastern Brazil. Fecal samples (n = 385) were obtained from young animals (up ten months old) evaluated means cent...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
abstract this study is an attempt to determine the effect of nano- technology education on science lesson for fifth grade in primary school in the city of kermanshah. this research is experimental and is conducted in the from of pre-test and post- test for the control group. an achievement test was administered to determine the rate of learning in the students. the research is an applied one. ...
AIM The aim of this study is evaluation of molecular assay and the standard staining method. BACKGROUND Cryptosporidium is a protozoon from coccidian subclass, which is one of the most important causes of diarrhea in children and immunocompromised individuals around the world. Diagnosis and treatment are necessary for mentioned cases. Usual diagnostic method for this parasite is fecal smear p...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
background: the main goal of the present study was to develop a new sensitive and specific pcr based method for identification of cryptosporidium sp. using novel primers from 18s ribosomal rna. cryptosporidiosis in high-risk host groups particularly in neonates and immuno-compromised individuals may result in death. to the best of our knowledge this is the first study regarding develop a new p...
