Endothelial cells (EC) derived from embryonic stem cells (ESC) require additional functional characterization before they are used as a cell therapy in order to enhance their potential for engraftment and proliferation. We explore several physiologically relevant functions of ESC-derived EC (ESCEC), such as its capacity to produce nitric oxide (NO), regulate permeability, activate and express s...

freeze-thaw is one of the most powerful weathering agents that may cause a rapid change in the initial engineering properties of stones, and limit their durability. freeze-thaw induces stress over the pores’ surface of stones. consequently, stone durability is closely related to its engineering and physical properties. the purpose of this study is estimating the engineering properties of deteri...

The role of limbic system structures in spatial orientation continues to be debated. The hippocampus (HPC) has been implicated in encoding symbolic representations of environments (i.e., cognitive map), whereas entorhinal cortex (EC) function has been implicated in self-movement cue processing (i.e., dead reckoning). These distinctions largely depend on the electrophysiological characteristics ...

The hippocampus plays an important role in the genesis of mesial temporal lobe epilepsy, and the entorhinal cortex (EC) may affect the hippocampal network activity because of the heavy interconnection between them. However, the mechanism by which the EC affects the discharge patterns and the transmission mode of epileptiform discharges within the hippocampus needs further study. Here, multielec...

BACKGROUND 70-80% of sporadic endometrial carcinomas are defined as endometrioid carcinoma (EC). Early-stage, well differentiated endometrial carcinomas usually retain expression of estrogen and progesterone receptors (ER and PR, respectively), as advanced stage, poorly differentiated tumors often lack one or both of these receptors. Well-described EC prognosis includes tumor characteristics, s...

using of different systems of soil plough after changing unconsciously and non-scientific of land use, other soil physical and chemical characteristics affected. this fact, especially in marginal lands and mountainous regions is more visible. this research compared with the purpose of studying land use changing on some soil physical and chemical characters like very tiny sand percent, ph, ec, c...

INTRODUCTION Emergency contraception (EC) reduces women's risk for pregnancy after unprotected intercourse, and women's awareness of the method is increasingly important for expanding access. However, knowledge of EC alone does not predict use, and few population data exist to describe EC use among those aware of the method. METHODS Using data from the 2003 California Health Interview Survey,...

Objective: Embryonal carcinoma (EC) is an uncommon subtype of intracranial germ cell tumors. The aim of this study is to determine the clinical characteristics and prognosis of EC. Methods: A total of ten EC patients were underwent surgical treatment. Three patients gained total resection (TR) and seven gained subtotal resection (STR). Radiotherapy was provided in nine patients and chemotherapy...

A highly sensitive microarray system for detecting protein-protein interactions has been developed. This method was successfully applied to analyze the interactions of heme-regulated phosphodiesterase from Escherichia coli (Ec DOS). To immobilize (His)6-Tag fused Ec DOS, anti-(His)6-Tag monoclonal antibody (anti-(His)6-Tag mAb) was initially immobilized on the solid surface, and (His)6-Tag fuse...

Cellulose and its derivatives are used as potential matrices for biomaterials and tissue engineering applications. The objective of present research was to investigate the influence of biofield treatment on physical, chemical and thermal properties of ethyl cellulose (EC) and methyl cellulose (MC). The study was performed in two groups (control and treated). The control group remained as untrea...
