The in vitro effects of arachidonyl-2-chloroethylamide (ACEA; a selective CB(1)-receptor agonist) and N-piperidin-l-yl)-5-(4-chlorophenyl)-1-(2,4-cochlorophenyl)-4-methyl-1H-pyrazole-3-carboxamide (SR141716A; a selective CB(1)-receptor antagonist) on lipid peroxidation (spontaneous and Fe (2+)-induced), total glutathione (GSH)-level and activity of antioxidant enzymes (superoxide dismutase, glu...
BACKGROUND Amyloid beta (Aβ) is believed to be responsible for the synaptic failure that occurs in Alzheimer's disease (AD), but there is little known about the functional impact of Aβ on intrinsic neuronal properties. Here, the cellular effect of Aβ-induced neurotoxicity on the electrophysiological properties of CA1 pyramidal neurons and the mechanism(s) of neuroprotection by CB1 cannabinoid r...
BACKGROUND The genome of the important industrial host Bacillus subtilis does not encode the glyoxylate shunt, which is necessary to utilize overflow metabolites, like acetate or acetoin, as carbon source. In this study, the operon encoding the isocitrate lyase (aceB) and malate synthase (aceA) from Bacillus licheniformis was transferred into the chromosome of B. subtilis. The resulting strain ...
Pseudomonas aeruginosa colonizes and can persist in the lungs of cystic fibrosis (CF) patients for decades. Adaptation of P. aeruginosa to the CF lung environment causes various genotypic and phenotypic alterations in the bacterium that facilitate persistence. We showed previously that isocitrate lyase (ICL) activity is constitutively upregulated in the P. aeruginosa CF isolate FRD1. We show he...
Neural stem cells (NSCs) are self-renewing cells that can differentiate into multiple neural lineages and repopulate regions of the brain after injury. We have investigated the role of endocannabinoids (eCBs), endogenous cues that modulate neuronal functions including neurogenesis, and their receptors CB(1) and CB(2) in mouse NSCs. Real-time PCR and Western blot analyses indicated that CB(1) is...
This paper presents the Flexible Radio Kernel (FRK), a configuration and execution management environment for hybrid hardware/software flexible radio platforms. The aim of FRK is to manage platform reconfiguration for multi-mode, multi-standard operation, with different levels of abstraction. A high level framework whose goal is to manage multiple Medium Access Control layers and to enable coop...
We compared the transcriptome, proteome, and nucleotide sequences between the parent strain Escherichia coli W3110 and the L-threonine-overproducing mutant E. coli TF5015. DNA macroarrays were used to measure mRNA levels for all of the genes of E. coli, and two-dimensional gel electrophoresis was used to compare protein levels. It was observed that only 54 of 4,290 genes (1.3%) exhibited differ...
Fibrinogen, 1 of 13 coagulation factors responsible for normal blood clotting, is synthesized by hepatocytes. Detailed roles of the orphan nuclear receptors regulating fibrinogen gene expression have not yet been fully elucidated. Here, we identified estrogen-related receptor gamma (ERRγ) as a novel transcriptional regulator of human fibrinogen gene expression. Overexpression of ERRγ specially ...

Background and objectives The relationship between the tumor microenvironment network of key signaling pathways in cancer plays a role occurrence development tumors. Tumor-associated macrophages (TAMs) are important inflammatory cells play an tumorigenesis progression. Macrophages malignant tumors, mainly M2 subtype, promote progression by producing cytokines down-regulating anti-inflammatory i...
