Selective inactivation of a1B-adrenoceptor (AR) by the sitedirected alkylating agent chlorethylclonidine (CEC) has been used as one of major pharmacological criteria to subclassify a1-AR; however, the mechanism for the differential CEC sensitivity of the two subtypes is uncertain, and the extent of CEC inactivation varies depending on the treatment employed. In this study, we examined the corre...

BACKGROUND Endothelial progenitor cells (CEPs) and circulating endothelial cells (CECs) are potential biomarkers of response to anti-angiogenic treatment regimens. In the current study, we investigated the effect of docetaxel and sunitinib on CEP/CEC kinetics and clinical response in castration resistant prostate cancer (CRPC) patients. PATIENTS AND METHODS Chemonaive patients with CRPC were ...

BACKGROUND The aim of this systematic review is to provide an overview of the diagnosis, treatment options and treatment-related complications of cervical esophageal carcinoma (CEC) and to subsequently provide recommendations to improve quality of care. DESIGN Studies were identified in PubMed, EMBASE and Web of Science. A total of 107 publications fulfilled the inclusion criteria and were in...

The myocardial effect of alpha-1A adrenoceptor (alpha-1 AR) agonists in neonatal rats are mediated by alpha-1A AR and not by alpha-1B AR, although both receptor subtypes are equally expressed; the functions of alpha-1B AR are not known. Here, we report that alpha-1 B ARs inhibit the activities of alpha-1A ARs in neonatal rat myocardium so that the inactivation of alpha-1 B ARs by chloroethylclo...

Capillary electrochromatography (CEC) combines the separation principle of HPLC (partitioning between mobile and stationary phases) with the high efficiency of capillary electroseparation methods. In CEC the electroosmotic flow (EOF) inherent in capillary electrophoretic separations is used to transport solute and mobile phase through a packed capillary column. The properties of the EOF provide...

A method of two-step gradient capillary electrochromatography (CEC) was developed to measure 12 carbonyls (aldehydes and ketones) in indoor air samples. The carbonyls were derivatized with 2,4-dinitrophenylhydrazine (DNPH) and then separated by a two-step gradient CEC on a C8 column. Effects of various instrumental conditions on the separation, including buffer concentration, organic modifiers,...

AIMS The quantification of circulating endothelial cells (CECs) in whole blood is a novel marker of direct endothelial injury and shows promise as a potential biomarker of cardiovascular (CV) risk. The inter-relationship(s) between CECs and predicted CV risk has not been explored in large cohort of 'high-risk' patients. We hypothesized that there would be a significant relationship between incr...

Purpose: B7 molecules are a family of proteins that co-stimulate T cells during immune activation. Normally the corneal epithelial cells (CEC) do not express these molecules on their cell surface. Tolllike receptors play an important role in the innate immune response to invading pathogens and recently have been demonstrated to be expressed on mice cornea. The objective of this study was to det...

Interphase chromatin is organized in distinct nuclear sub-compartments, reflecting its degree of compaction and transcriptional status. In Caenorhabditis elegans embryos, H3K9 methylation is necessary to silence and to anchor repeat-rich heterochromatin at the nuclear periphery. In a screen for perinuclear anchors of heterochromatin, we identified a previously uncharacterized C. elegans chromod...
