Animal studies showed that male gastric tissues respond more rapidly to Helicobacter pylori (H.pylori) infection but the possible mechanisms remained unclear. There is no data about gender specific activity of Androgen receptor (AR) as an independent unfavorable prognostic factor in gastric cancer and its interactions with H.pylori and angiogenesis in both genders. To compare the pathogenesis o...

Background: Resveratrol is a natural polyphe- nolic compound, synthesized by plants as a phytoalexin and protects against ultraviolet radiation and fungal infection. Nitric oxide is formed from L-arginine through nitric oxide synthases (NOS), a group of enzymes that structurally resemble cytochrome P-450 reductase. In females, circulating NO is increased during follicle development and decrease...

Pleomorphic adenoma (PA) is the most common benign tumor of major salivary glands and intra nasal PA unusual which may be misdiagnosed as malignancy. A 65-year-old female presented with unilateral bleeding obstruction in right cavity for 6 months. Local examination showed polypoid mass surgically excised. HPE classic triphasic component epithelial, myoepithelial cartilaginous stromal elements p...

In this study, we examined the effect of a combination surface topographies (fiber alignments) and different stiffness poly(L-lactic acid) (PLLA) substrates on direct relationship between anti-cancer drug (CDDP) sensitivity for MDA-MB-231 cells mesenchymal properties under both normal hypoxic conditions. addition, studied induction epithelial–mesenchymal transition (EMT). The CDDP treatment hyp...

Epithelial myoepthial carcinoma (EMEC) is rare, low grad tumor with epithelial and myoepithelial components frequent local recurrence, also called glycogen rich adenoma (clear cell pattern), myoepithelioma (spindle plamocytiod patterns), (if only differentiation marked cytologic atypia). Occurs most frequently in the major salivary glands accounts for approximately 1% of all gland neoplasms tha...

conclusions results of the current study showed the high prevalence of m. tuberculosis among the patients with lung cancer; therefore, it seems that continuous surveillance is essential to monitor the m. tuberculosis in the patients with lung cancer. results the subjects included 252 (66.3%) males and 128 (33.7%) females. based on cultural and microscopic methods, m. tuberculosis infection was ...
