Soil cation exchange capacity (CEC) depends on the extent and negative charge density of surfaces of soil mineral and organic components. Soil water sorption also depends on the extent of such surfaces, giving thus way to significant relationships between CEC and hygroscopic moisture (HM) in many soils. In this work, we explored whether CEC could be accurately predicted from HM in agricultural ...

PURPOSE To investigate the effects of hepatocyte growth factor (HGF) and a small applied electric field (EF) on corneal epithelial cell (CEC) migration. METHODS Primary cultures of bovine CECs were exposed to an EF (25-250 mV/mm) in the presence or absence of HGF (100 ng/mL). The rate and directionality of CEC migration were quantified. The expression of HGF receptors (HGFRs), p42/44 mitogen-...

Background Circulating endothelial cells (CECs) are a potential biomarker of angiogenesis. CECs increase in numbers after vessel injury. Higher CEC numbers are reported in cancer patients. Most methods for CEC detection and enumeration rely on flow cytometry (FCM); however, there is no agreement on CEC phenotype and the detection method to be used. This leads to uncertainty about the clinical a...

Self-healing injectable hydrogels can be formulated as three-dimensional carriers for the treatment of neurological diseases with desirable advantages, such as avoiding the potential risks of cell loss during injection, protecting cells from the shearing force of injection. However, the demands for biocompatible self-healing injectable hydrogels to meet above requirements and to promote the dif...

INTRODUCTION Endothelin-1 (ET-1), circulating endothelial cells (CEC) and endothelial progenitor cells (EPC) are well-known modulators of endothelial function with important cardiac effects after an acute myocardial infarction. However, the relationship between them has never been assessed. The objective of the present study was to establish the relationship between ET-1, CEC, and EPC concentra...

BACKGROUND Pulmonary vasodilators in general and prostacyclin analogues in particular have improved the outcome of patients with pulmonary arterial hypertension (PAH). Endothelial dysfunction is a key feature of PAH and we previously described that circulating endothelial cell (CEC) level could be used as a biomarker of endothelial dysfunction in PAH. We now hypothesized that an efficient PAH-s...

This report describes an in vitro system that could be useful for investigating corneal neovascularization. When isolated bovine capillary endothelial cells (CEC) were cocultivated with rabbit corneal keratocytes, capillary-like cords extended actively from the endothelial cells in the multilayers of the keratocytes. The developing cords continued to elongate, branch out, and anastomose with ea...

The communication interface between support element applications and applications running on the zSeries system processors is an essential part of the zSeries system design. For example, the interface is used to load firmware during startup, it is used for service actions such as configuring or deconfiguring I/O channels, and for many other functions. It must be fast, reliable, and failsafe. A ...

A novel mode of capillary electrochromatography (CEC), called dynamically modified strong cation-exchange CEC (DMSCX-CEC), is described in this paper. A column packed with a strong cation-exchange (SCX) packing material was dynamically modified with a long-chain quaternary ammonium salt, cetyltrimethylammonium bromide (CTAB), which was added to the mobile phase. CTAB ions were adsorbed onto the...
