How visual scene memory is processed differentially by the upstream structures of the hippocampus is largely unknown. We sought to dissociate functionally the lateral and medial subdivisions of the entorhinal cortex (LEC and MEC, respectively) in visual scene-dependent tasks by temporarily inactivating the LEC and MEC in the same rat. When the rat made spatial choices in a T-maze using visual s...

The mammary ducts of humans and mice are comprised of two main mammary epithelial cell (MEC) subtypes: a surrounding layer of basal MECs and an inner layer of luminal MECs. Breast cancer subtypes show divergent clinical behavior that may reflect properties inherent in their MEC compartment of origin. How the response to a cancer-initiating genetic event is shaped by MEC subtype remains largely ...

background: salivary gland tumors constitute an important part of oral and maxillofacial pathology. pleomorphic adenoma (pa) and mucoepidermoid carcinoma (mec) are the most common benign and malignant salivary gland tumors. fascin is an actin-bundling protein that increases the motility of normal and transformed epithelial cells. the aims of the study were to determine the expression of fascin ...

Salivary gland carcinomas are a rare and clinically diverse group of neoplasms among which mucoepidermoid carcinomas (MEC) are reported to be most frequently occurring. MEC display a variety of biological behaviors and variable natural history. We report a case of mucoepidermoidcarcinom. Histopathological features suggested intermediate grade mucoepidermoid carcinoma. Surgical resection was don...

The medial septum (MS) is required for theta rhythmic oscillations and grid cell firing in the medial entorhinal cortex (MEC). While GABAergic, glutamatergic, and cholinergic neurons project from the MS to the MEC, their synaptic targets are unknown. To investigate whether MS neurons innervate specific layers and cell types in the MEC, we expressed channelrhodopsin-2 in mouse MS neurons and use...

BACKGROUND Mucoepidermoid carcinoma (MEC) can be classified into low-, intermediate-, and high-grade tumors based on its histological features. MEC is mainly composed of three cell types (squamous or epidermoid, mucous and intermediate cells), which correlates with the histological grade and reflects its clinical behavior. Most cancers exhibit reduced methylation of repetitive sequences such as...

in children as young as our patient (7 years) have been reported (3). Histologically, MEC is characterized by three cell types: mucinous, squamous, and clear (4). Lesions are typically well-circumscribed and demonstrate peritumoral fibrosis, variability in the epithelial lining, mucinous, and papillary features (2,5). Immunohistochemical analysis reveals positive staining for cytokeratin and ca...

Damage caused by water shortages leads to physiological and biochemical changes in metabolism of plants and make them predispose to attack by pests and diseases and reduce the quality of the crops. In order to evaluate the effect of supplemental irrigation on safflower fly (A. helianthi) population of safflower cultivars, an experiment conducted as a split plot based on randomized complete bloc...
