  • Introduction: As one of azide salts, lead azide is well known, because it is used as a detonator for air bags of automobiles. Recently, sodium azide has been frequently used for suicides and homicidal attempts. In this chapter, therefore, analytical methods are described only for sodium azide. Sodium azidea is being well used as an antiseptic (preservative)b in biochemical researches and as a material for synthesis of organic compounds.

  • Delayed hypersensitivity mechanisms directed by drug-specific T cells are probably the most important mechanisms in the etiology of the most common drug eruptions—morbilliform exanthems—and also of rare and severe forms such as hypersensitivity syndrome, acute generalized exanthematous pustulosis (AGEP), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN). Drugspecific T cells have been detected in these types of drug eruptions. Contrary to what has been believed for years, the antigen is more often the native drug itself than its metabolites.

  • These reactions are characterized by one or more sharply demarcated, erythematous lesions, sometimes leading to a blister. Hyperpigmentation results after resolution of the acute inflammation. With rechallenge, the lesion recurs in the same (i.e., fixed) location. Lesions often involve the lips, hands, legs, face, genitalia, and oral mucosa and cause a burning sensation. Most patients have multiple lesions. Fixed drug eruptions have been associated with phenolphthalein, sulfonamides, cyclines, dipyrone, NSAIDs, and barbiturates.

  • Prescription and over-the-counter drugs help millions of people with devastat-ing diseases and chronic conditions. But in the process, these medications can also deplete the body’s natural stores of vitamins, minerals, and hormones—the very nutrients you need to keep energy levels high, fend off infections, and be healthy. Pharmacist Suzy Cohen calls these medications “drug muggers,” and she says it’s essential to replenish what a drug mugger steals from your body in order to feel your best and avoid side effects.

  • Great efficiencies have been achieved in the drug discovery process as a result of technological advances in target identification, high-throughput screening, high-throughput organic synthesis, just-in-time in vitro ADME (absorption, distribution, metabolism, and excretion), and early pharmacokinetic screening of drug leads. These advances, spanning target selection all the way through to clinical candidate selection, have placed greater and greater demands on the analytical community to develop robust high-throughput methods.

  • The modern drug discovery process, in general, involves the identification of a biochemical target (usually protein target), screening of synthetic compounds or compound libraries from combinatorial chemistry/natural sources for a lead compound, and optimization of the lead compound (activity, selectivity, pharmacokinetics, etc.) for recommending a potential clinical candidate.

  • In the drug discovery area, a compound with desired therapeutic properties is identified, and its structure may be modified by synthetic alterations to enhance potency and specificity or to decrease toxicity and undesired side effects. The lead drug candidate is then transitioned into the drug development area. Only small amounts of drug (typically less than a gram) are required to support the required studies in the Drug Discovery area. However larger amounts are required to support the studies conducted in the Drug Development area.

  • The lead agency must also coordinate with other agencies and review security plans for infrastructure and utilities that could threaten event security (local water supply, water treatment facilities, electricity supply, communications grid, sewer system, computer systems, etc.). At some special events, manhole covers have been welded shut near the event venues. Often, newspaper dispensers and public trash cans are removed before an event (they can be hiding places for bombs and can be used as missiles to harm law enforcement or destroy property). When such measures...

  • Leadership is required from City staf and elected oicials, from organizations operating in diverse sectors across the city, and from Vancouver residents—many of whom have already contributed to the development of this plan. he City will need to lead the way in its own operations as well, demonstrating what a Greenest City looks like in City-run buildings, facilities, and operations. Leadership from other levels of government and other public sector agencies will also be critical to our success. Action A plan like this is only useful when it is acted upon.

  • Over the past few decades, research in …nancial economics has taken a high e¤ort to increase the understanding of the volatility patterns of stock market returns. Indeed, good knowledge of return volatility is crucial for portfolio choice, risk management and derivatives asset pricing. Perhaps the most robust empirical regularity of stock return volatility is volatility clustering. As …rst noted by Mandelbrot (1963) when referring to stock market returns, "large changes tend to be followed by large changes, of either sign, and small changes tend to be followed by small changes".

  • In addition to family planning services, the WHP offers preventive health screening services. For many women, the periodic family planning visit may be their only point of contact for preventive care and screening. An analysis of patients at family planning centers found that the majority (62%) considered the center their usual source of care and that poor (73%) and uninsured (75%) women were even more likely to depend on the centers as their usual source of care.

  • early half of providers indicated their interest in participating but limited time availability resulted in them completing both the baseline questionnaire and interview by email or mail. Results from the baseline questionnaire were for only descriptive purposes and were not further analyzed. Findings from the transcripts of the phone interviews were analyzed to identify common themes and experiences. Our final sample included 5 Planned Parenthood affiliates and 16 non-PPFA or “alternative” providers (although one did not complete the baseline profile).

  • The leading features content is very vaguely considered in the reports. Material selection and second extent configurations (e.g. texture, colour and light) can best identify the answer to question A. For example, the content is described as follows: “door handle should be made in aluminium and polished to a glossy smooth surface without texture, to convey the cold, cynical, military-industrial terms”. The structural principle for the door handle is its function as a tool for twisting and pulling, and for a computer mouse a resting hand shape.

  • There is a pervasive perception among providers that treating patients with TB on an outpatient basis will lead to increased TB transmission. With the advent of modern antituberculosis chemotherapy, admission to the hospital has been shown not to be necessary for effective treatment of TB. Studies have shown that, not only does outpatient treatment of TB achieve cure rates comparable to inpatient care, outpatient therapy is not associated with an increase in TB transmission in the community.
