introduction: 17β-estradiol modulates nociception by binding to estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and gabaa receptors. beside its autonomic functions, paragigantocellularis lateralis (lpgi) nucleus is also involved in pain modulation. the aim of the current study was to investigate the role of the intracellular estrogenic ...

background: colorectal cancer is one of the most important causes of morbidity and mortality in the world. it has been suggested that tissue inhibitor of metalloproteinase-1 (timp-1) plays a particular role in cancer promotion. the objective of the present study was to compare the effect of repeated measurement of carcinoembryonic antigen (cea) and timp-1 plasma levels in a follow-up response t...

background: mesenchymal stem cells (mscs) are multipotential cells and their therapeutic potency is under intense investigation. studying the effect of different induction factors on mscs could increase our knowledge about the differentiation potency of these cells. one of the most important sources of these factors in mammalian body is platelet. platelet lysate (pl) contains many growth factor...

background: the aim of present study was to evaluate the protective efficacy of live recombinant l. tarentolae expressing kmp11-ntgp96-gfp fusion as candidates for live engineered recombinant vaccine against visceral leishmaniasis in balb/c mice. methods: kmp-11 and nt-gp96 genes cloned into the pjet1.2/blunt cloning vector and then into pegfp-n1 expression vector. the kmp-11, nt-gp96 and gfp f...

introduction: oral premalignant lesions are conditions having high potential tendency for transformation into malignancy. the use of a conservative and effective treatment modality is one of the best strategies for cancer prevention. photodynamic therapy (pdt) is a non-invasive method for topical and selective treatment of oral precancerous lesions. the present study was taken up to determine t...

a simple, green synthesis of n-alkyl-3-acetyl-2-methylpyrrole derivatives using zno nanoparticles from the three component reaction of aliphatic amines, acetylacetone (as a 1,3-dicarbonyl compound) and α-haloketones under solvent-free condition is described.

background: early childhood caries (ecc) is a common health problem in the developing countries. basic knowledge about the etiology and pathogenesis of ecc plays an important role in its prevention. objective: to determine the relationship between salivary tlr-2 concentration and early childhood caries formation methods: twenty-eight children with ages ranging from 36 to 71 months (15 in ecc gr...
