Response generalization

We imagine a finite-duration shock pulse arriving at some point in the material. The strain as a function of time is shown as the upper diagram in Fig. 7.11 for elastic-perfectly-plastic response (solid line) and quasi-elastic response generally observed (dash-dot line). The maximum volume strain = 1 - PoIp is designated...

A broad and vigorons T cell response generally accompanies elimination of HBV as well as HCV infection. By contrast, patients with chronic hepatitis B or C tend to have late, transient, or narrow T cell responses. In a long-term follow-up of HBV-infected patients receiving HPC transplants from HBV-immune individuals, 20 of 31 recipients cleared their HBV infection (Hui et al. 2005). In principle, these results encourage the development of adoptive T cell transfer strategies for the treatment of chronic viral hepatitis. However, it is still controversial whether induction of an efficient T cell response is the cause or the consequence of viral clearance. Furthermore, T cell responses do not only contribute to virus control but also to disease pathology (Rehermann and Nascimbeni 2005). 

Despite the work of Overton and Meyer, it was to be many years before structure-activity relationships were explored further. In 1939 Ferguson [10] postulated that the toxic dose of a chemical is a constant fraction of its aqueous solubility hence toxicity should increase as aqueous solubility decreases. Because aqueous solubility and oil-water partition coefficient are inversely related, it follows that toxicity should increase with partition coefficient. Although this has been found to be true up to a point, it does not continue ad infinitum. Toxicity (and indeed, any biological response) generally increases initially with partition coefficient, but then tends to fall again. This can be explained simply as a reluctance of very hydrophobic chemicals to leave a lipid phase and enter the next aqueous biophase [11]. An example of this is shown by a QSAR that models toxicity of barbiturates to the mouse [12] ... 

The individual responsiveness to desmopressin is consistent, and a test dose administered at the time of diagnosis or prior to therapy is the best predictor of response. Generally, DDAVP is more effective in vWD than in hemophilia patients, with an average 30% to 50% increase in vWF and factor VIII levels. In patients with an adequate response, desmopressin is first-line therapy because it allows for once-daily administration (elevates plasma levels for 8-10 hours), does not pose a threat in terms of viral transmission, and the cost is substantially less than that of the plasma-derived products. Fibrinolysis inhibitors (50-60 mg/kg of aminocapriotic acid every 4—6 hours or trenex-amic acid 10-15 mg/kg every 8-12 hours) and OCs are used successfully in the management of epistaxis and menorrhagia or as adjuvant treatments. 

To define a feature extraction procedure it is necessary to consider that the output signal of a chemical sensor follows the variation of the concentration of gases at which it is exposed with a certain dynamics. The nontrivial handling of gas samples complicates the investigation of the dynamics of the sensor response. Generally, sensor response models based on the assumption of a very rapid concentration transition from two steady states results in exponential behaviour. 

Stabilize the patient s asthma before treatment is started. Initially, use aerosol concurrently with usual maintenance dose of systemic steroid. After approximately 1 week, start gradual withdrawal of the systemic steroid by reducing the daily or alternate daily dose. Make the next reduction after 1 to 2 weeks, depending on response. Generally, these decrements should not exceed 25% of the prednisone dose or its equivalent. A slow rate of withdrawal cannot be overemphasized. 

Three terms beginning with the letter R are used to describe the improvement of a depressed patient after treatment with an antidepressant, namely response, remission, and recovery. The term response generally means that a depressed patient has experienced at least a 50% reduction in symptoms as assessed on a standard psychiatric rating scale such as the Hamilton Depression Rating Scale (Fig. 5—2). This also generally corresponds to a global clinical rating of the patient as much improved or very much improved. Remission, on the other hand, is the term used when essentially all symptoms go away, not just 50% of them (Fig. 5-3). The patient is not better the patient is actually well. If this lasts for 6 to 12 months, remission is then considered to be recovery (Fig. 5—3).

Deterministic Responses. At the low levels of exposure of concern to waste classification, deterministic responses generally are important only for hazardous chemicals, but not for radionuclides. 

In classifying waste, deterministic responses generally should be of concern only for hazardous chemicals (see Section 3.2.2.1). Therefore, the only important issue for risk assessment is the most appropriate approach to estimating thresholds for induction of responses in humans. The primary concern here is that consistent approaches should be used for all substances that induce deterministic effects. NCRP s recommendation that nominal thresholds in humans should be estimated using the benchmark dose method and a safety factor of 10 or 100, depending on whether the data were obtained in a study in humans or animals (see Section 6.1.2.1), is intended to provide consistency in estimating thresholds for all substances that cause deterministic effects.

As soon as the final IND is completed, it is submitted (see the checklist). The FDA conducts a formal review (response generally issued within 30 days of submission). That response (generally provided in a conference call) may be full approval with permission to conduct the proposed study of studies, approval with some restriction on the proposed study or studies, or a rejection. Each requires a response from the submitter. 

There may be other solutions of the problem at hand. The system thus asks whether we are satisfied with the solution just given or whether it should try to find alternate solutions. In some implementations the system poses the respective question explicitly, awaiting a specified response (generally yes or no). Other systems just wait for the user to act. The convention in these systems is often that a carriage return signals accepting the solution, where as input of a indicates that alternate solutions are to be found. In the present case, there are no other solutions. Thus, if we ask for more we get the answer no. Another interesting question may be... 

It is possible to conduct predictive irritation assays in man as only a small area of the skin needs to be tested (provided that systemic toxicity is low and informed consent is obtained). Patch test responses generally heal rapidly, within a week or so. More severe reactions should be evaluated periodically over a longer period to determine how the inflammatory response is resolved. Some subjects may develop changes in pigmentation level at the test site following severe responses. It... 

The net effect of dopamine is thus likely to depend on the degree of activation of D1 and D2 receptors, on the contribution of NMDA and AMPA receptor-operated channels to the synaptic response, and the interplay between VSCCs and synaptic responses. Generally, the D2 effect predominates, i.e. dopamine inhibits depolarization and firing evoked by glutamate (Cepeda et al., 1992, 1993). 

Induction of de novo synthesis of a-amylase by GA in isolated aleurone layers is evident after a lag period of approximately 8 hr following administration of the hormone. In keeping with hormone responses generally, GA must be present continuously if the de novo synthesis of hydrolases is to be sustained. Synthesis of new RNA is essential to the GA-induction of de novo synthesis of hydrolases. Actinomycin D, an inhibitor of RNA synthesis, inhibits the synthesis and release of a-amylase if the inhibitor is presented during the first 7 to 8 hr after treatment. Inhibitors of protein synthesis, such as cycloheximide, also inhibit GA-induction of hydrolases. And, interestingly, abscisic acid, a growth-inhibiting hormone, inhibits GA-induced a-amylase synthesis as well.

The term stakeholder is often used in disposal and other aid operations. Everybody can be regarded as a stakeholder - the only variable is the level of responsibility. Generally speaking the main stakeholders are the developing country, the former manufacturer of the pesticides and the commercial disposal company, as well as the donor organisation. The duty of each partner organisation is specified in a document such as a Memorandum of Implementation, for example.

The relative response factor (RRF) of 1 defines that an impurity and active at identical concentrations have the same analytical response. Generally, no corrections for RRF need to be performed if the RRF of particular impurities are between 0.8 and 1.2. If the relative response factors are outside this region, the impurities can be overestimated or underestimated. For example, if impurity X has an RRF of 0.5 compared to the active, then it would be underestimated and if impurity Y has an RRF of 1.5 compared to the active, then it can be overestimated. In these cases the RRF must be taken into account when determining the percent of related substances during evaluation of the purity of the DS or the DR The following equation could be used. 

Aspirin hypersensitivity is also a potential concern and can occur in two ways (1) a respiratory reaction, which is more profitimd in patients with rhinitis, asthma, or nasal polyps, or (2) a typical type I hypersensitivity reaction, including urticaria, wheals, angioedema, itching, rash, bronchospasm, laryngeal edema, hypotension, shock, or syncope. This latter response generally occurs within 1 hour of aspirin ingestion. Such aspirin intolerance may manifest itself in 4% to 19% of patients with asthma and may approach 40% of steroid-dependent asthmatics.
