The objective of the study was to investigate the effect of exogenous nitric oxide on cellular response and production of secondary metabolites in Catharanthus roseus callus. The Cell suspension and callus of C. roseus were treated with sodium nitroprusside, then cell viability, morphology, the amount of H2O2, proline, lipid peroxidation, the activity of superoxide dismutase, catalase and perox...

objective: today, aids is considered as a global problem and many efforts to generate an effective vaccine against this disease have been made, but remain inconclusive. dna vaccines are a member of the new generation of vaccines that can efficiently stimulate the immune system. however, recent findings indicate low immunogenicity for these vaccines and it is believed that these types of vaccine...

background: elevated level of plasma homocysteine has been related to various diseases. patients with hyperhomocysteinemia can develop hepatic steatosis and fibrosis. we hypothesized that oxidative stress induced by homocysteine might play an important role in pathogenesis of liver injury. also, the cellular response designed to combat oxidative stress is primarily controlled by the transcripti...

purpose: evaluation of humoral and cellular immune responses of naturally infected dogs against type i (rcpb) (recombinant cycsteine proteinase b), and ii (rcpa) (recombinant cycsteine proteinase a) recombinant cysteine proteinases and c-terminal extension (cte) of leishmania infantum (l. infantum). materials and methods: in this study, fourteen infected dogs (7 with symptoms, 7 asymptomatics)...

esophagus cancer is the eighth most common cancer worldwide and particularly high in an area extending from the southern border of the caspian sea in iran across central asia to china. since information about this mysterious disease is poor, proteomics may be solving this enigma. altering gene expression in cancer cell is a remarkable indicator can be detected by proteomics techniques and bioin...

in this study, we investigate the immunostimulatory effects of alcoholic extract of the coffee seed on cell-mediated immune response andcyclophosphamide-induced (cp) immunosuppressed mice. the assessment of cellular immune function was carried out by the measurement of delayed-type hypersensitivity (dth) response. according to the literature survey, cyclophosphamide has only suppressing effect ...

the aim followed in the present study was an evaluation of the adaptive immune traits (cellular and humoral) of both males and females in iranian commercial vs azarbayijan native fowls. information obtained from cellular and humoral responses of 49 birds of arian broiler line. 79 azarbayijan native birds were made used of. total antibody titration, immunoglobulin y titration (igy), and immunogl...

The response to drought stress is a complicated process involving stress sensing, intracellular signaltransduction, and the execution of a cellular response. Transcription factors play important roles in the signaling pathways including abiotic stress. In the present study a rice NF-YA transcription factor gene was partially characterized following dehydration. Disrupting the gene via a T...
