Shock

A life-threatening condition that requires immediate medical intervention. It is characterized by reduced blood flow that may result in damage of multiple organs. Types of shock include cardiogenic, hemorrhagic, septic, anaphylactic, and traumatic shock. [from NCI]

Sodium arsenite

A highly soluble, orally available trivalent arsenic-containing telomerase inhibitor with potential antitumor activity. Although the exact mechanism through which sodium metaarsenite exerts its effect has yet to be fully elucidated, this agent appears to target and bind to telomeric sequences, specifically TTAGGG repeats, leading to a shortening of telomeres, and subsequent induction of apoptosis and inhibition of tumor cell growth. In addition, sodium metaarsenite also leads to the translocation of the catalytic subunit of telomerase into the cytoplasm and inhibition of the activity of telomerase. Telomerase is active in most tumors cells and is responsible for the maintenance of telomere length and plays a key role in cellular proliferation, but is quiescent in normal, healthy cells. The susceptibility to sodium metaarsenite seems to be inversely correlated with initial length of telomeres. [from NCI]

Nitric oxide

A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP. [from MeSH]

Inflammation

A localized protective response resulting from injury or destruction of tissues. Inflammation serves to destroy, dilute, or wall off both the injurious agent and the injured tissue. In the acute phase, inflammation is characterized by the signs of pain, heat, redness, swelling, and loss of function. Histologically, inflammation involves a complex series of events, including dilatation of arterioles, capillaries, and venules, with increased permeability and blood flow; exudation of fluids, including plasma proteins; and leukocyte migration into the site of inflammation. [from NCI]

Hereditary spastic paraplegia

The hereditary spastic paraplegias (HSPs) are clinically and genetically heterogeneous disorders characterized by lower extremity spasticity and weakness (occurring in variable proportion). When symptoms begin after childhood, they usually progress slowly and steadily. When symptoms begin in very early childhood, they may be non-progressive and resemble spastic diplegic cerebral palsy. HSP is classified as "uncomplicated" if neurologic impairment is limited to lower extremity spastic weakness, hypertonic urinary bladder disturbance, and mild diminution of lower extremity vibration sensation. HSP is classified as "complicated" if the impairment present in uncomplicated HSP is accompanied by other systemic or neurologic abnormalities such as ataxia, seizures, cognitive impairment, dementia, amyotrophy, extrapyramidal disturbance, or peripheral neuropathy (in the absence of other causes for these additional features). Neurologic examination of individuals with uncomplicated HSP demonstrates variable degrees of increased muscle tone (spasticity) particularly in the hamstrings, quadriceps, gastrocnemius-soleus, and adductor muscles; weakness in the iliopsoas, hamstring, and tibialis anterior muscles; hyperreflexia at the patella and ankles; often (though not always) mildly reduced vibration sensation in the toes; extensor plantar responses; and spastic gait. [from GTR]

Physiological stress

The unfavorable effect of environmental factors (stressors) on the physiological functions of an organism. Prolonged unresolved physiological stress can affect HOMEOSTASIS of the organism, and may lead to damaging or pathological conditions. [from MeSH]

Mediator of inflammation

Protein binding

The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments. [from MeSH]

Prostaglandin

A group of compounds derived from unsaturated 20-carbon fatty acids, primarily arachidonic acid, via the cyclooxygenase pathway. They are extremely potent mediators of a diverse group of physiological processes. [from MeSH]

Dinoprostone

A synthetic prostaglandin E2 (PGE2) analogue with smooth muscle contraction inducing property. It has been suggested that PGE2 regulates the intracellular levels of cyclic 3, 5-adenosine monophosphate (cAMP) by activating adenylate cyclase and thereby increases cellular membrane calcium ion transport. By acting directly on the myometrium, dinoprostone induces uterine and gastrointestinal smooth muscle contractions. [from NCI]
