Human endothelial cells (EC) augment CD40 ligand (CD40L) expression on PHA-activated CD4+ T cells at early times (e.g., 4-6 h). Fixed EC, devoid of mRNA, are comparable to living EC in their capacity to augment early CD40L expression on CD4+ T cells. Fixed EC increase T cell mRNA expression of both IL-2 and CD40L compared with PHA alone at 6 h. EC are unable to increase the rate of transcriptio...

An acidic phospholipase A2 (EC-I-PLA2) has been purified from the Indian saw-scaled viper (Echis carinatus) venom through a combination of column chromatography and electrophoresis. EC-I-PLA2 has a molecular weight of 16000 by SDS-PAGE. It was focussed between pH 4.2 and 4.8 by isoelectro focussing. EC-I-PLA2 was non-lethal to mice and devoid of neurotoxicity, myotoxicity, anticoagulant activit...

The purpose of this paper is to present the perceptions and experiences of Electronic Commerce (EC) implementation in Australia. The study is investigated from the perspective of Smalland Medium-sized Enterprises (SMEs) and the framework of implementation is represented by the extent of deployment. Based on the sample of about 115 small businesses in Australia, this paper uses regression modell...

The special nature of groceries, especially perishables, challenges the possibilities of digital channels i.e. computers and networks to improve customer service. We report the findings of theme interviews on the potential of electronic commerce (EC) of groceries with 33 experts of grocery industry and EC, most of them senior executives, in 23 organisations in Finland during the Autumn of 1997....

Many different thermal, optical, and thermal/optical carbon analysis methods for organic carbon (OC), elemental carbon (EC) or black carbon (BC) have been applied throughout the world to evaluate visibility and the Earth’s radiation balance. Dozens of intermethod and interlaboratory comparison studies have been conducted. Several of these studies are catalogued and summarized here. BC or EC con...

The realization of a complete techno-economy through significant carbon dioxide (CO2) reduction in the atmosphere has been explored to promote low-carbon economy various ways. CO2 reactions (CO2RRs) can be induced using sustainable energy, including electric and solar systems such as electrochemical (EC) CO2RR photoelectrochemical (PEC) systems. This study summarizes fabrication strategies for ...

the objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (sm) supplemented with an enzyme complex (ec). a total of 1920 animals of the cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four sm levels and three enzymes utilization types)...

The role of mechanical regulation in driving human induced pluripotent stem cell (hiPSC) differentiation has been minimally explored. Although endothelial cell (EC) fate from hiPSCs has been demonstrated using small molecules to drive mesoderm induction, the effects of substrate stiffness with regard to EC differentiation efficiency have yet to be elucidated. We hypothesized that substrate comp...

Garcinia mangostana Linn extract (GME) is a natural product that has received considerable attention in cancer therapy, and has the potential to reduce side effects of chemotherapeutics and improve efficacy. We formulated GME-encapsulated ethyl cellulose (GME-EC) and a polymer blend of ethyl cellulose and methyl cellulose (GME-EC/MC) nanoparticles. We achieved high drug-loading and encapsulatio...
