An emergent behavior is a global, qualitatively novel system behavior, which results from the interaction of the system’s components, is maintained for a specific period of time, and ceases to exist when particular components are removed from the system. The formation of a complex snow-flake patterns, the buildup of a traffic jams, the erection of termite cathedrals, the development of troubles...

We discuss about gr -connectedness and different properties of it, such as remarks, examples theorems.

In the fission yeast Schizosaccharomyces pombe, the pgr1+ gene encoding glutathione (GSH) reductase (GR) is essentially required for cell survival. Depletion of GR caused proliferation arrest at the G1 phase of the cell cycle under aerobic conditions. Multicopy suppressors that restore growth were screened, and one effective suppressor was found to be the trx2+ gene, encoding a mitochondrial th...

BACKGROUND A specific type of partial AZFc deletion, called 'gr/gr' deletion, was recently proposed as genetic risk factor for spermatogenic impairment and testis cancer. Since both pathologies can be part of the testicular dysgenesis syndrome (TDS), we aimed to define the role of 'gr/gr' deletion in the aethiopathogenesis of another component of the TDS: cryptorchidism. METHODS A total of 14...

Purified glucocorticoid receptor (GR) from rat liver was used for a quantitative analysis of the protein-DNA interaction at specific GR-binding segments within the 5'-long terminal repeat of the mouse mammary tumor virus. A truncated receptor was generated and used to demonstrate formation of heterodimeric GR, which furthermore was shown to be in rapid equilibrium with receptor-monomer. The rel...

OBJECTIVE Recent evidence suggests a metabolic contribution of cytochrome P450 enzymes (CYPs) to the drug-resistant phenotype in human epilepsy. However, the upstream molecular regulators of CYP in the epileptic brain remain understudied. We therefore investigated the expression and function of pregnane xenobiotic (PXR) and glucocorticoid (GR) nuclear receptors in endothelial cells established ...
