aim : we aimed to study the expression of cd24 and cd133 in colorectal cancer and normal adjacent tissues to assess a relationship between these markers and clinic-pathological characteristics and patient’s survival. background : cancer stem cells are a group of tumor cells that have regeneration and multi-order differentiation capabilities. patients and methods : expression of cd24 and cd133 w...

Epithelial ovarian cancer is one of the increasingly incident malignancies that is notorious because of its evasiveness for early diagnosis and high mortality rates. Epithelial ovarian cancers are highly dependent on pathologic vasculature and Vascular Endothelial Growth Factor is known to be one of the most efficient angiogenic factors. Polymorphisms of the VEGF gene, in this study, were asses...

OBJECTIVES To identify differentially expressed miRNA between oral squamous cell carcinoma (OSCC) and non-cancer (NC) and to associate these with clinico-pathological parameters. MATERIALS AND METHODS miRNA microarray profiling was utilized to obtain the expression profile of miRNAs in four OSCC and four NC samples. The expression of miR-31 and miR-375 was further validated in 26 OSCC and thr...

OBJECTIVES To compare the clinico-pathological features of collapsing glomerulopathy (CG) at a tertiary hospital in Saudi Arabia with the world literature. Methods: In a retrospective study, all biopsy-diagnosed cases of CG between 2004-2015 were identified and analyzed, at King Khalid University Hospital, King Saud University, Riyadh. The clinico-pathological findings along with prognosis were...

Background: Breast Cancer in the Middle East and North Africa region (MENA) occurs in a younger age group of patients and is more aggressive than in Europe and North America. Little is known about the presence of immune infiltration and clinico-pathologic correlates in patients from the MENA region. Immune infiltration of most solid tumors carries a prognostic role. Adaptive immune cells and cy...

Histoid lepro sy, originally described by Wade in 1960 (1 2) is generally regarded as a distinct clinico-pathological entity. It presents as cutaneous or subcutaneous nodular and / or plaque-like lesions arising from apparently normal skin. The lesions are characterized, histologically , by tumorous collections. of spindle-shaped cells arranged in a crisscross fashion giving them a resemblance ...

The samples from pleural and pericardial effusion, in which immature haematopoietic cells had been identified cytologically, were re-examined. The results were then analysed along with the clinico-biological context and compared to published data. The aim was to determine the frequency, the type and the context of haematopoietic cell identification in pleural and pericardial fluid effusion. In ...

The contribution of genetic variants in RhoA and ROCK1 genes towards prostate cancer risk has not been reported before. We genotyped six potentially functional genetic variants in a case-control study of 1699 subjects. Overall, we found rs2410 mutant allele and rs2269736 wild allele were risk factors for prostate cancer. Individuals carrying more than two risk alleles were exposed to hazard of ...

The challenges regarding seamless integration of distributed, heterogeneous and multilevel data arising in the context of contemporary, post-genomic clinical trials cannot be effectively addressed with current methodologies. An urgent need exists to access data in a uniform manner, to share information among different clinical and research centers, and to store data in secure repositories assur...

Corticobasal degeneration (CBD) is a rare sporadic 4-repeat tauopathy. We report here the first Polish case of pathologically proven CBD. Our patient developed clumsiness of the right hand at age 63 years. During the course of his illness he suffered from progressive asymmetric parkinsonism unresponsive to dopaminergic therapy. Focal dystonia affecting right upper extremity, non-fluent aphasia,...
