  • High-pressure liquid-solid chromatography (HPLC) is rapidly becoming the method of choice for separations and analysis in many fields. Almost anything that can be dissolved can be separated on some type of HPLC column. However, with this versatility comes the necessity to think about the separation desired and the best way to achieve it. HPLC is not now and probably never will be a turn-key, push-button type of operation.

  • Foreword: It was with great pleasure that I accepted the invitation to write the foreword for Drugs and Poisons in Humans. A Handbook of Practical Analysis. Dr. Osamu Suzuki and Dr. Mikio Yashiki, two outstanding Japanese scientists, fi rst published the Handbook in Japanese in 2002. Specialists throughout Japan contributed analytical methods for a wide variety of therapeutic and illicit drugs, pesticides, and natural toxins and alkaloids. In fact, rarely has such a wide spectrum of analytes and metabolites been addressed within a single reference manual....

  • Introduction: Small amount of drugs and poisons incorporated into human bodies are hidden among large amounts of biological components, such as proteins, lipids, nucleic acids and membranes. It is not easy to detect only a target compound from such complicated matrices. Before instrumental analysis, extraction procedure is usually essential and very important.

  • Central to this book are two ideas. The first is that Fluid Mechanics is relevant to a wide variety of problems that are priorities in the early 21st century, three of which are health, the environment, and energy. The second idea is that researchers in this field are applying novel methods to address these problems. Even on its most basic level, Fluid Mechanics is challenging.

  • Introduction: Forensic autopsy is an important task for proving crimes medically; unfortunately, every department of legal medicine of Japanese universities is suffering from insufficient staffs and budget. About 30 years ago, one of the authors started the analysis of drugs and poisons at the Department of Legal Medicine, Hiroshima University School of Medicine. At that time, the author did not have much knowledge about poison analysis; but it is a good memory that many good friends of toxicological societies gave the author many useful suggestions on analytical methods.

  • This book presents and develops major numerical methods currently used for solving problems arising in quantitative finance. Our presentation splits into two parts. Part I is methodological, and offers a comprehensive toolkit on numerical methods and algorithms. This includes Monte Carlo simulation, numerical schemes for partial differential equations, stochastic optimization in discrete time, copula functions, transform-based methods and quadrature techniques. Part II is practical, and features a number of self-contained cases.

  • Introduction: Pentazocine ( Fig. 5.1) is a non-narcotic analgesic, but shows mild dependence; there are many cases of pentazocine abuse especially for medical and co-medical workers. The drug is being regulated as a subclass compound of narcotics (DEA class: IV). Pentazocine in both antemortem and postmortem specimens is being analyzed by GC [1–4], HPLC [5–7] and GC/MS [8]. In this chapter, a simple method for GC/MS analysis of pentazocine in human whole blood and urine is presented. ⊡ Figure 5.1 Structures of pentazocine and dextromethorphan (IS).

  • Introduction: Propionic acid derivative analgesic-antipyretics ( Table 2.1) are non-steroidal and antiinflammatory drugs. As one of mechanisms of their pharmacological actions, inhibition of prostaglandin biosynthesis can be mentioned. Although fatal cases due to propionic acid derivative analgesic-antipyretics are not many in the world, the incidence of poisoning (including survived cases) by this drug group is relatively high among therapeutic drugs in Japan [1].

  • The second section of the book involves the regional biogeography of individual taxa. This section begins with a chapter by Alberto Taylor and his colleagues on the biogeography of cycads in Central America. Their natural history and experimental ecological methods integrate the evolutionary context of the cycad lineage with contemporary autecology, and they elucidate biogeographic patterns and conservation priorities, the latter of which are under-appreciated but pressingly important in Central America.

  • Introduction: Acetylsalicylic acid (ASA, aspirin) ( Figure 4.1) has been being used as an analgesic-antipyretic for a long time; it is contained in many of over-the-counter drugs. Although ASA is relatively safe, various poisoning symptoms, such as lowered consciousness levels, hypotension, pulmonary edema and convulsion, were reported upon ingestion of a large amount of this drug [1]. For analysis of ASA, methods by HPLC [2–19], GC [20–23], GC/MS [24] and capillary electrophoresis [25–27] were reported; among these methods, HPLC is most popular. ...

  • Introduction: Determination of methemoglobin (Met-Hb) in blood is important for the diagnosis of poisoning by oxidants, such as nitrite, nitrate, chlorate, chlorite, alkyl nitrites, nitroglycerin, aniline and other compounds. In 1938, Evelyn and Malloy [1] had devised a photoelectric method for determination of Met-Hb in blood. Minor modifications of this method were made by several researchers to increase sensitivity [2–4]. These methods are based on a phenomenon that the absorbance maximum of weakly acidic Met-Hb at 630 nm disappears by addition of cyanide.

  • Introduction: As many as 5,000–6,000 mushroom species are growing in the world. Among them, only about 1,000 species are named; the majority of them are unnamed. The number of species of edible mushrooms in Japan is about 300; that of toxic mushrooms is said to be about 30. Various types of toxic mushrooms exist; some show high toxicity, while others show hallucinogenic actions. Morphological and chemical analyses for mushrooms are occasionally required in forensic science practice.
