Chinese hamster Wg3-h-o cells which were descended from DON cells have been mutagenized and selected for derivatives defective in metabolic cooperation via gap junctions (i.e., mec-). The selection protocol included four consecutive cycles of cocultivating mutagenized cells, deficient in hypoxanthine phosphoribosyltransferase (HPRT) and wild-type cells in the presence of thioguanine (cf Slack, ...

Solid oxide fuel cells (SOFCs) can be operated in a reversed mode as electrolyzer cells for electrolysis of H2O and CO2. In this paper, a 2D thermal model is developed to study the heat/mass transfer and chemical/electrochemical reactions in a solid oxide electrolyzer cell (SOEC) for H2O/CO2 co-electrolysis. The model is based on 3 sub-models: a computational fluid dynamics (CFD) model describi...

Waste heat can be captured as electrical energy to drive hydrogen evolution in microbial reverse-electrodialysis electrolysis cells (MRECs) by using thermolytic solutions such as ammonium bicarbonate. To determine the optimal membrane stack configuration for efficient hydrogen production in MRECs using ammonium bicarbonate solutions, different numbers of cell pairs and stack arrangements were t...

Freezing-cryosurgery, and electrolysis-electrochemical therapy (EChT), are two important minimally invasive surgery tissue ablation technologies. Despite major advantages they also have some disadvantages. Cryosurgery cannot induce cell death at high subzero freezing temperatures and requires multiple freeze thaw cycles, while EChT requires high concentrations of electrolytic products-which mak...

Geobacter sulfurreducens PCA completely oxidized lactate and reduced iron or an electrode, producing pyruvate and acetate intermediates. Compared to the current produced by Shewanella oneidensis MR-1, G. sulfurreducens PCA produced 10-times-higher current levels in lactate-fed microbial electrolysis cells. The kinetic and comparative analyses reported here suggest a prominent role of G. sulfurr...

background: salivary gland tumors form a major area in the field of oral pathology. b-cell lymphoma -2 (bcl-2) is an anti-apoptotic gene with up-regulation in various neoplasms. the aim of the present case-control study was to comparatively investigate the expression of bcl-2 protein in pleomorphic adenoma (pa) and mucoepidermoid carcinoma (mec) and assess its potential diagnostic role in diffe...

The aim of the present study was to investigate the effect of realgar on the viability, proliferation and apoptosis in the human chronic lymphocytic leukemia (CLL) cell line, MEC‑1. Potential mechanisms mediating the effect were also explored in the experiment. Cultured MEC‑1 cells were incubated with various concentrations of realgar for 24, 48 and 72 h. A WST‑8 assay was employed to evaluate ...

We show that energetic charged particles are produced during electrolysis of a D2O solution of Li2SO4 in a cell with a platinum anode and a palladium cathode. CR-39 plastic detectors, designed for recording alpha particles from radon decay, were immersed in the electrolyte during electrolysis. They recorded significantly larger numbers of energetic particle tracks than were recorded by control ...

The mechanisms that enable the hippocampal network to express the appropriate spatial representation for a particular circumstance are not well understood. Previous studies suggest that the medial entorhinal cortex (MEC) may have a role in reproducibly selecting the hippocampal representation of an environment. To examine how ongoing MEC activity is continually integrated by the hippocampus, we...

► Microbial salinity-reduction electrolysis cells (MSCs) can treat salinewastewater. ► In MSCs, organic matter and salt ions were removed simultaneously. ► Ion-exchange membranes were not damaged for three months in MSCs. ► Exoelectrogens can generate high currents with salinities up to 36 g/L TDS. ⁎ Corresponding author.
