Date of acceptance / Kabul tarihi: March 09, 2016 / 09 Mart 2016 ABSTRACT: Role of galectin-3 and CD44v6 expression in the differentiation of the follicular carcinoma and adenoma of the thyroid Objective: The role of the galectin-3 and CD44v6 expression in the differentiation of the thyroid follicular carcinoma and follicular adenoma were investigated in many preoperative cytologic samples and ...

Salivary gland neoplasms (SGN) remain a diagnostic dilemma due to their heterogenic complex behavior. Their diverse histomorphological appearance is attributed the underlying cellular mechanisms and differentiation into various histopathological subtypes with overlapping fea-tures. Diagnostic tools such as fine needle aspiration biopsy, computerized tomography, magnetic resonance imaging, posit...

The theme of this paper is the construction of finite-difference approximations to the first derivative in the presence of Dirichlet boundary conditions. Stable implementation of splitting-based discretisation methods for the convectiondiffusion equation requires the underlying matrix to be skew symmetric and this turns out to be a surprisingly restrictive condition. We prove that no skewsymmet...

Substantial behavioural and neuropsychological evidence has been amassed to support the dual-route model of morphological processing, which distinguishes between a rule-based system for regular items (walk-walked, call-called) and an associative system for the irregular items (go-went). Some neural-network models attempt to explain the neuropsychological and brain-mapping dissociations in terms...

Social identity theory postulates that people are motivated to achieve a positive and distinct identity. One strategy in response to threatened identity is differentiation, the occupation of vacant social niches. Studies by Lemaine (1974) demonstrated that individuals when feeling inferior do in fact use differentiating behavior to justify themselves, both in situations with and without explici...

How do youths' personality reports differ from those of adults? To identify the year-by-year timing of developmental trends from late childhood (age 10) to early adulthood (age 20), the authors examined Big Five self-report data from a large and diverse Internet sample. At younger ages within this range, there were large individual differences in acquiescent responding, and acquiescence variabi...

Over the past two decades a variety of mechanisms regulating cellular differentiation have been uncovered. These include signaling by morphogens or membrane-associated ligands and asymmetric segregation of cytoplasmic components. Most of these processes are driven by protein coding genes. Here I describe another possible cellular differentiation mechanism that involves asymmetric segregation of...

The aim of the study is to describe the differentiation of the cortical plate in human foetuses aged 9-11 weeks. Histological sections showed that in this early period of development the cortical plate is differentiated into two zones. The external zone is composed of vertical columns of cells, which are perpendicular to the cortical surface. The internal zone is wider and consists of irregular...

Two experiments examined the psychological and biological antecedents of hierarchical differentiation and the resulting consequences for productivity and conflict within small groups. In Experiment 1, which used a priming manipulation, hierarchically differentiated groups (i.e., groups comprising 1 high-power-primed, 1 low-power-primed, and 1 baseline individual) performed better on a procedura...
