Since tumor cells are more dependent on glycolysis for energy supply than other cells, we tested whether its inhibition by 2-deoxy-D-glucose (2-DG) affects tumor growth. Male Wistar rats were inoculated in the liver with tumor cells from a chemically induced colonic adenocarcinoma. From day 5 after inoculation 2-DG (400 mg/kg/24 h) was continuously infused into the hepatic artery for 5 days; co...

Mitochondrial dysfunction is a hallmark of beta-amyloid (Aβ)-induced neurotoxicity in Alzheimer's disease (AD), and is considered an early event in AD pathology. Diammonium glycyrrhizinate (DG), the salt form of Glycyrrhizin, is known for its anti-inflammatory effects, resistance to biologic oxidation and membranous protection. In the present study, the neuroprotective effects of DG on Aβ(1-42)...

A new method to solve the single and multi-objective distribution expansion planning problems including DG is investigated in this paper. The sizing and placement of DG as well as the required power of the main grid would be optimized using proposed method to meet the demand. Binary Particle Swarm Optimization (BPSO) algorithm is used to solve the optimization problem for three objective functi...

2-Deoxyglucose (2-DG), a nonmetabolizable glucose analogue, blocks glycolysis at the phosphohexose isomerase step and has been frequently used as a glucose starvation mimetic in studies of a wide variety of physiological dysfuctions. However, the effect of 2-DG on protein glycosylation and related signal pathways has not been investigated in depth. In HeLa, an HPV18-positive cervical carcinoma ...

The water soluble porphyrin tetrakis(4-N-methylpyridyl)porphine (H2TMpyP) and its copper(II) derivative (CuTMpyP) convert Z-poly(dG-dC) to the B-form. For H2TMpyP, the fraction Z character (fr-Z) is given by fr-Z = 1.0 - 21 rO and for CuTMpyP, fr-Z = .94 - 12 rO where rO identical to [Porphyrin]O/[DNA]O. Neither the manganese(III) derivative of of this porphyrin (MnTMpyP) nor tetrakis(2-N-methy...

In view of previous studies demonstrating a significant correlation between adenosine triphosphate (ATP) depletion and impairment of chemotaxis (CTX) during granulocyte (PMN) storage, we sought to quantitate the relationship between CTX and PMN energy metabolism. We incubated PMNs at 37 degrees C with 2-deoxyglucose (2-dg) in the presence of 5 mmol/L glucose. As expected, ATP inhibition by 2-dg...

To better understand encoding and decoding of stimulus information in two specific hippocampal sub-regions, we isolated and co-cultured rat primary dentate gyrus (DG) and CA3 neurons within a two-chamber device with axonal connectivity via micro-tunnels. We tested the hypothesis that, in these engineered networks, decoding performance of stimulus site information would be more accurate when sti...

There is a considerable amount of work in the scientific literature on nonlinear (“paradoxical”) effects, but their toxicological significance for body still poorly understood. Plant growth regulators are biologically active substances at level low and ultra-low doses concentrations, they widely used agriculture. To date, mechanisms toxic specific effects body, presence “paradoxical” have not b...

This work describes the construction of a sensitive, stable, and label-free sensor based on a dual-gate field-effect transistor (DG FET), in which uniformly distributed and size-controlled silicon nanowire (SiNW) arrays by nanoimprint lithography act as conductor channels. Compared to previous DG FETs with a planar-type silicon channel layer, the constructed SiNW DG FETs exhibited superior elec...
