direct agglutination test (dat) is a sensitive and simple method, which is applicable in field and unequipped laboratories. in order to evaluate dat in the diagnosis of toxoplasma infections, the antigen was prepared in the protozoology unit, school of public health and it was used in the following studies. a- 251 serum samples collected from suspected toxoplasmosis out-patients were examined f...

hemorrhoids is one of the most common diseases of mankind. there are different methods of treatment, but many problems and complications are associated with the use these modalities. dc electrotherapy of hemorrhoids is an alternative method which offsets many of these conditions. two hundred and ten patients with 426 hemorrhoidal tags of different grades underwent dc electrotherapy by a dc gene...

this study aimed at comparing the impact of two types of teacher feedback on iranian efl learners’ writing ability and their verb tense consistency in l2 writing. following the administration of a standardized language proficiency test (preliminary english test), sixty-two participants were selected and were randomly assigned to the control (direct-only correction) and experimental (direct meta...

graphene modified glassy carbon electrodes have been developed for the determination of calcium dobesilate in pharmaceutical formulations. the prepared graphene and cnts were used as a conductive substrate for electrochemical study of calcium dobesilate. the direct electrochemistry of calcium dobesilate showed a reversible cyclic voltammogram with a formal potential of 133 mv (vs. ag/agcl) for ...

The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...

objective(s):the aim of this study was to improve flowability and compressibility characteristics of starch to use as a suitable excipient in direct compression tabletting. quasi-emulsion solvent diffusion was used as a crystal modification method. materials and methods: corn starch was dissolved in hydrochloric acid at 80˚c and then ethanol as a non-solvent was added with lowering temperature ...

thyroid hormones regulate the metabolisms of all cells including hepatocytes, and hence, modulate hepatic function. hyperthyroidism is one of the most common endocrine disorders characterized by increased secretion of thyroid hormones t3 and/or t4. this study investigated frequency of abnormal liver function tests in the patients with hyperthyroidism that referred to imam reza hospital of kerma...

conventional methods of pear breeding, largely based on intra- and inter-specific hybridization, are difficult because pear is highly heterozygous, polygenic and has a long juvenile period. genetic improvements of pear cultivars are possible through induction of mutations and gene transfer by genetic engineering. a general prerequisite for these approaches is to establish an efficient plant reg...
