specific and non- specific cellular immune responses were studied in 20 amoebiasis cases and 10 controls. all the study cases and controls were indians living in varanasi, india. ten amoebic liver abscess cases were patients admitted to university hospital. ten non-invasive intestinal amoebiasis cases constituted the second study group. non-specific immune responses were studied using e-rosette...

micrornas (mirnas) represent a class of small non-coding rna molecules that regulate gene expression at the post-transcriptional level. they play a crucial role in diverse cellular pathways. ionizing radiation (ir) is one of the most important treatment protocols for patients that suffer from cancer and affects directly or indirectly cellular integration. recently it has been discovered that mi...

objective: hypericum perforatum (st. john's wort) has long been used in traditional medicine to treat a variety of internal and external ailments. the present study was done to evaluate the immumodulatory potentials of the hydroalcoholic extract of h. perforatum. materials and methods: twenty male balb/c-mice were randomly allocated in two equal groups and immunized with sheep red blood ce...

catharanthus roseus is a medicinal and ornamental plant with growing attention toward its economical value. cell suspension from c. roseus were treated with 0 to 60mm of cadmium nitrate for 1, 3 and 6 days, then cell viability was determined using trypan blue and mtt assay. cell morphology was investigated using 0, 10, 30 and 50 mm of cadmium nitrate as selected dose for 3 days. callus of c.ros...

the prevalence of hepatitis c virus (hcv) is approximately 3% around the world. this virus causes chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. the effectiveness of interferon-α and ribavirin therapy is about 50% and is associated with significant toxicity and cost. hence, generating new vaccines or drugs is an obligation. however, there is no vaccine available for clinical u...

in this work quantitative structure activity relationship (qsar) methodology was applied for modeling and prediction of cellular response to polymers that have been designed for tissue engineering. after calculation and screening of molecular descriptors, linear and nonlinear models were developed by using multiple linear regressions (mlr) and artificial neural network (ann) methods. the root m...

Free radicals are normally produced by living organism, at controlled production rate they perform physiological functions as signal transduction molecules. However, situations leading to an overproduction that surpasses antioxidant capacity creates oxidative stress. Consequently, damage to the cell membrane, protein, DNA and cell death are observed. Dairy cattle are susceptible to oxidative st...
