this study was performed in order to define the cellular immune response of 12 recovered cutaneous leishmaniasis subjects to different soluble antigens of the amastigote form of leishmania major. a soluble leishmanial antigen preparation (sla) derived from highly-purified amastigotes from infected nude mice was fractionated by mono q column using fast protein liquid chromatography (fplc) system...

background: many in vitro studies suggested that choline incorporation into many types of tumors is related to cell proliferation. whether in vivo choline incorporation is related also to cell proliferation or not was my question. therefore, the aim of this pilot study was to investigate the relationship of in vivo [methyl- 14c]-choline incorporation and in vivo [methyl-3h]- thymidine incorpora...

objective(s): scutellarin, a flavonoid extracted from the medicinal herb erigeron breviscapus hand-mazz, protects neurons from damage and inhibits glial activation. here we examined whether scutellarin may also protect neurons from hypoxia-induced damage. materials and methods: mice were exposed to hypoxia for 7 days and then administered scutellarin (50 mg/kg/d) or vehicle for 30 days cognitiv...

objective: by date investigations have indicated the presence of stem cells within the pulp tissue of both temporary and permanent human teeth. in the present study, these stem cells were compared in terms of their growth kinetics and culture requirements. materials and methods: stem cells within the pulp of the human third molar (permanent tooth) and the deciduous incisor (temporary tooth) wer...

background: some antidepressant drugs can promote neuronal cell proliferation in vitro as well as hippocampal neurogenesis in human and animal models. furthermore, adipose tissue is an available source of adult stem cells with the ability to differentiate in to multiple lineages. therefore, human adipose-derived stem cells (hadscs) may be a suitable source for regenerative medical applications....

background: determination of the division history of t cells in vitro is helpful in the study of effector mechanisms against infections. technique described here uses the intracellular fluorescent label carboxyfluorescein diacetate succinimidyl ester (cfse) to monitor the proliferation. methods: in a cross sectional study, blood samples were collected from 7 volunteers with history of cutaneous...

background the mutations of lhbs in pre-s, especially in pre-s2, are definitive in hepatocellular carcinoma (hcc) associated with hbv. however, the mechanisms of the n-glycosylation modification in lhbs are unclear. the n-glycosylation modification of lhbs affects endoplasmic reticulum stress, cell proliferation and its secretion which was further studied. objectives the objectives of our studi...

aim : in this paper effect of combinational usage of calprotectin and etoposide on ags cell line is studied. background : application of combined toxic agents such as etoposide and cicplatin are commonly used for chemotherapy purposes. as a matter of fact, calprotectin and etoposide were both applied on human gastric adenocarcinoma cell line (ags) as antitumor agents. both calprotectin and etop...

back ground: candida albicans is a member of the normal human microflora. c. albicans cell wall is composed of several protein and carbohydrate components which have been shown to play a crucial role in c. albicans interaction with the host immune system. major components of c. albican cell wall are carbohydrates such as mannans, β glucans and chitins, and proteins that partially modulate the h...

Nano-fertilizers can increase value of products in agriculture. Iron plays many important and essential roles in plant growth and development as compared to other micronutrients. In the present study, effects of different levels of enriched nano chelated Iron fertilizer (25, 50, 100, and 200 mg l-1)  were investigated in comparison with the common Iron (FeSO4.7H2O) on in vitro proliferation of ...
