The human organism is a biophysical system. Stress represents a normal reaction of the organism which appears as a response to an aggression situation which requires an unusual and quick adaptation effort from the organism.

Regulator of G-protein signaling (RGS) proteins were originally identified as negative regulators of G-protein-coupled receptor (GPCR) signaling via their GTPase-accelerating protein (GAP) activity. All RGS proteins contain evolutionarily conserved RGS domain; however, they differ in their size and regulatory domains. RGS1 and RGS10 are smaller than other RGS proteins, and their functions involve various inflammatory responses including autoimmune responses in both the periphery and the central nervous system (CNS). Neuroinflammation is the chronic inflammatory response in the CNS.

An immuno-homologue of maize Ca2+/calmodulin (CaM)dependent protein kinase with a molecular mass of 72 kDa was identified in pea. The pea kinase (PsCCaMK) was upregulated in roots in response to low temperature and increased salinity. Exogenous Ca2+ application increased the kinase level and the response was faster than that obtained following stress application. Low temperaturemediated, but not salinity-mediated stress kinase increase was inhibited by the application of EGTA and W7, a CaM inhibitor....

Here we show, for the ®rst time, thein vitro formation of ®lamentous aggregates of phosphorylated tau protein in SH-SY5Y human neuroblastoma cells. The formation of suchaberrant aggregates, similar to thoseoccurringinvivoin Alzheimer's disease and other tauopathies, requires okadaic acid, a phosphatase inhibitor, to increase the level of phos-phorylated tau, and hydroxynonenal, a product of oxidative stress that selectively adducts and modi®es phosphorylated tau.

Hsp105aisoneof themajormammalianheat shockproteins that belongs to the HSP105/110 family, and is expressed at especially high levels in the brain as compared with other tissues in mammals. Previously, we showed that Hsp105a prevents stress-induced apoptosis in neuronal PC12 cells, and is a novel anti-apoptotic neuroprotective factor in the mammalian brain.

The role of oxidative stress in pilocarpine-induced status epilepticus was investigated by measuring lipid peroxidation level, nitrite content, GSH con-centration, and superoxide dismutase and catalase activities in the hippo-campus of Wistar rats. The control group was subcutaneously injected with 0.9% saline. The experimental group received pilocarpine (400 mgÆkg )1 , subcutaneous). Both groups were killed 24 h after treatment.

Plasma concentrations of free fatty acids are increased in metabolic syn-drome, and the increased fatty acids may cause cellular damage via the induction of oxidative stress. The present study was designed to determine whether the increase in fatty acids can modify the free sulfhydryl group in position 34 of albumin (Cys34) and enhance the redox-cycling activity of the copper–albumin complex in high-fat diet-induced obese mice.

Oviparously developing embryos of the crustaceanArtemia franciscana encyst and enter diapause, exhibiting a level of stress tolerance seldom seen in metazoans. The extraordinary stress resistance of encysted Artemia embryos is thought to depend in part on the regulated synthesis of artemin, a ferritin superfamily member.

Substantial levels of trehalose accumulate in bacteria, fungi, and inverte-brates, where it serves as a storage carbohydrate or as a protectant against environmental stresses. In higher plants, trehalose is detected at fairly low levels; therefore, a regulatory or signaling function has been proposed for this molecule.

Iron regulatory protein-1 binding to the iron-responsive element of mRNA is sensitive to iron, oxidative stress, NO, and hypoxia. Each of these agents changes the level of intracellular ATP, suggesting a link between iron levels and cellular energy metabolism.

In mammals, cytochrome P450 17a-hydroxylase⁄17–20 lyase (CYP17), which is encoded by a single gene, plays a critical role in the production of mineralocorticoids, glucocorticoids and androgens by the adrenal cortex. Two CYP17 isoforms with unique catalytic properties have been identified in the South African Angora goat (Capra hircus), a subspecies that is susceptible to cold stress because of the inability of the adrenal cortex to produce sufficient levels of cortisol.

Phosphorylation of the a-subunit of the eukaryotic initiation factor 2 (eIF2) on Ser51 is an early event associated with the down-regulation of protein synthesis at the level of translation and initiation of a transcrip-tional program. This constitutes a potent mechanism to overcome various stress conditions.

Peroxiredoxin V (PRDX5) is a member of the family of mammalian pro-teins that neutralize reactive oxygen species. The PRDX5gene is constitu-tively expressed at a high level in many human tissues, but functional elements of its promoter responsible for a high basal activity in the absence of oxidative stress have still not been identified.

Heat shock protein 90 (Hsp90) is a molecular chaperone required for the activity of many of the most important regulatory proteins of eukaryotic cells (the Hsp90 ‘clients’). Vertebrates have two isoforms of cytosolic Hsp90, Hsp90aand Hsp90b. Hsp90bis expressed constitutively to a high level in most tissues and is generally more abundant than Hsp90a, whereas Hsp90a is stress-inducible and overexpressed in many cancerous cells.

Quinolinic acid (QUIN) excitotoxicity is mediated by elevated intracellular Ca 2+ levels, and nitric oxide-mediated oxidative stress, resulting in DNA damage, poly(ADP-ribose) polymerase (PARP) activation, NAD + deple-tion and cell death. We evaluated the effect of a series of polyphenolic compounds [i.e. epigallocatechin gallate (EPCG), catechin hydrate, curcu-min, apigenin, naringenin and gallotannin] with antioxidant properties on QUIN-induced excitotoxicity on primary cultures of human neurons....
