background: fine-needle aspiration of breast cancer often provides moderate cellular material that is representative of the tumors. these samples can be used not only for cytological diagnosis but also to obtain information on the prognosis and likely response to therapy by using immunohistochemical staining studies. methods: we assessed the degree of correlation between prognostic biologic mar...

results in patients with high breast densities, malignant cases (61.2%) were significantly more in comparison to patients with low breast densities (37.3%) (p= 0.007, or=2.66 95% ci=1.29-5.49). after adjusting for age, density was associated with malignancy in age groups <46 years (p=0.007), and 46-60 years (p=0.024) but not in age group >60yrs (p=0.559). adjusting for menopausal status, densit...

recent studies have shown that glucocorticoids may have modulatory effect on anxiety reactions. this effect may occur with opioid system interference. according to that, the purpose of this research is to assess the effect of dexamethasone as glucocorticoid agonist and its interaction with opioidergic system on the anxiety modulatory effect in plus maze model in mice. male white mice with mediu...

discussions in comparison to the control of wy14643, sandoz58-035, c9 and t11-cla, epa increased the pparα mrna levels (p = 0.024, p = 0.041, p = 0.043, and p = 0.004, respectively), even though, la had no significant effect on the pparα mrna expression (p = 0.489). materials and methods this experimental study investigated the effects of c9, t11-conjugated linoleic acid (c9, t11-cla). alpha li...

results the tlr3 protein in the ach group tended toward reduction although the p value of the comparison between the ach group and hd group was not statistically significant. the tlr3 levels in the hcc, ac, and cir groups were higher than those in the hd and ach groups. tlr3 was not interrelated with all costimulation proteins in the dcs and t cells in all five groups. no group presented any in...

background and objective: breast cancer is the commonest cancer of indian women. estrogen and progesterone expression is seen in benign breast lesions and in breast carcinoma associated with good prognostic parameters and it correlates well with response to hormone therapy. although a lot of studies have been conducted in the past on hormone receptor expression in breast cancer and few have cor...

conclusions p. gingivalis and p. intermedia could play a role in implant failure by changing the expression profiles of genes related to bone formation and resorption. results viability was reduced to 56.8% (p. gingivalis) and 52.75% (p. intermedia) at 1000 multiplicity. amongst 48 genes examined, expressions of bmper, smad1, il8 and nfrkb were found to be highly upregulated by both bacterial c...

introduction: pro-inflammatory chemokines and cytokines   such as mcp-1 and il6 can activate microglial cells that has found in some neuro-inflammatory disorders. hypoxia activates cerebral endothelial cells to release these pro-inflammatory mediators. we aimed to investigate the anti-hypoxic effects of different doses of some gabaergic agents. materials and methods: we randomly divided 150 mic...

there is interrelationship between the immune and nervous systems that is accomplished by the molecular mediators. dopamine is one of the most important neurotransmitters. five different dopamine receptor genes (drd1, drd2, drd3, drd4, and drd5) have been recognized and cloned. the expression of the dopamine receptors is well characterized in the brain but little work has been done to examine t...

objective(s) several lines of evidence indicate that neuropeptides exhibit protective properties against gastroduodenal ulcers. neurotensin, a gut-brain neuropeptide, is implicated in a number of physiological processes in the central nervous system and peripheral tissues including gastrointestinal tract. in the present study, we aimed to investigate the gastroprotective potential of either per...
