Action responsibility

Cleanup actions taken to deal with a release or threat of release of a hazardous substance that could affect humans and/or the environment. The term "cleanup" is sometimes used interchangeably with the terms remedial action, removal action, response action, or corrective action. 

They block the reuptake and also enhance the release of NE, DA and 5-HT (Ben-erjee et al. 2004). There is considerable evidence suggesting that the primary action responsible for their psychostimulant effects is on the CNS DA system (Nehlig 1999).

SSRIs have been approved for the treatment of the majority of anxiety disorders, except agoraphobia and specific phobia. The mechanisms of action responsible for SSRIs anxiolytic activity remain to be fully delineated. Understanding of pre- and postsynaptic receptor regulation with chronic treatment and cross-system effects are critical in furthering our imderstanding of these drugs. Increasing specificity may improve clinical efficacy. 

The first agent proven to be effective in OCD was the TCA, clomipramine. Its efficacy in pediatric-age patients with OCD was demonstrated in two double-blind, placebo-controlled studies (146, 147). These findings were further supported by a double-blind crossover study with desipramine ( 148). This latter study provided support for serotonin uptake inhibition being the mechanism of action responsible for the efficacy of clomipramine in OCD. Despite this evidence, there are several limitations to the use of clomipramine because of its multiple mechanisms of action ... 

Additional research has found that high doses of atrazine administered to female SD rats - acutely or chronically -reduce the output of luteinizing hormone (LH), a pituitary hormone that is necessary for timely ovulation and normal estrous cycling. This specific inhibitory mechanism of atrazine action is a key step in the mode of action responsible for mammary tumors in the SD rat. 

Increasing the temperature generally speeds up a reaction. Lowering the temperature of food by refrigeration causes a decrease in the rate of the bacterial action responsible for food spoilage. The factors that affect reaction rates are not desirable or undesirable in themselves and can be useful manipulators to serve a desired purpose.

Meat taken from the room where the Tenderay process is carried out is immediately cooled below 40° F. to inhibit the enzyme action responsible for the tenderization. 

The exact mechanism of action responsible for St. John s wort s neurological effects is not known. Additionally, it is not known if any one chemical constituent is responsible for its activity or if it is a combination of multiple components. It is known that the extracts of H. perforatum appear to inhibit the synaptic uptake of several neurotransmitters including norepinephrine, serotonin (5-HT), and dopamine (3,11-13). Rats that were fed high doses of hypericum extracts standardized to flavonoids (50%), hypericin (0.3%), and... 

When mixture component chemicals are determined to act through independent toxic modes of action, response addition is recommended. When component chemicals act via a similar toxic mode of action, dose addition is recommended [1]. In response addition, the net response estimated for the mixture is equivalent to the sum of the individual component responses [1], The assumption is that for a toxicity following exposure to a mixture, the type or degree of adverse effect caused by one mixture component has no direct impact on the type or degree of adverse effect caused by a second component. Response addition requires dose-response data for all components of a mixture sufficient to define the slope of the dose-response carve with a degree of certainty sufficient to support predictions of risk at uncharacterized, environmentally relevant doses. 

This is where the neurotransmitters enter the picture. The neurotransmitters are actually chemical substances, created and stored by the neurons until they are needed. Once the neuron receives the signal to carry a message on, the neurotransmitters are released. They jump across the synapse gap — or, more accurately, squirt across — and attach themselves to specially designated receptors on the other side. Each neurotransmitter has its own particular receptor. Some trigger an action response others send a signal inhibiting a response.

Birds respond differently than mammals to oral nitroaromatic and nitramine exposure. Although hematological parameters are often affected by high exposures, the resiliency of the avian hematopoietic system and the refractory nature of the nucleated red blood cells suggest that the blood is not a sensitive target. Explosive compounds appear to predominantly affect the central nervous system (CNS) and cause neuromuscular effects (e.g., convulsions, lethargy, and tremors). The moiety as well as the potential mode of action responsible for these effects is largely unknown. 

Additives that control bacterial growth may therefore exert both biostatic and biocidal effects. The mechanism of action responsible for each effect is not generally the same. Biostatic action is considered to represent metabolic inhibition which is released when the additive is removed. Biocidal activity causes irreversible damage to a vital structure or function of the cell. Dispersants may also be used to prevent attachment to a surface.

Step 5 Significant impact determination - If the responsible person or group decides that a proposed action will not significantly affect the environment, then a so called negative determination is made (Step 6B) which may involve a public notice or explanation steps are then taken to proceed with the proposed action responsible person a group simply identifies such cases...

This enabler puts into place supply chain performance measures. Often, objectives are set but systems do not exist to measure performance against those objectives. This can be especially true when the source of the data is a supplier or a customer. Another problem occurs when measurement cycles are out of sync with the action response cycle. If measurements are much more frequent than the responses, the company may be drowning in useless data. If the measurement cycle is far longer than the response cycle, then responses may be too late to make timely and effective corrections.
