  • The 5¢ flanking region of the bile salt export pump (Bsep) gene was systematically analysed to provide the basis for understanding the mechanisms which regulate Bsep transcription. In addition substrates and drugs were investigated for their ability to alter Bsep promoter activity. Bsep promoter function was restricted to hepatocyte derived HepG2 cells. The 5¢ deletional analysis revealed a biphasic shape of reporter gene activities, indicating a suppressive element between nucleotides )800 and )512. ...

  • Trypanosoma cruzi, the parasitic protozoan that causes Chagas disease, contains a major cysteine proteinase, cruzipain. This lysosomal enzyme bears an unusual C-terminal extension that contains a number of post-translational modifications, and most antibodies in natural and experimen-tal infections are directed against it. In this report we took advantage of UV-MALDI-TOF mass spectrometry in conjunction with peptide N-gly-cosidase F deglycosylation and high performance anion exchange chroma-tography analysis to address the structure of the N-linked oligosaccharides present in this domain. ...

  • In recent years, the remarkable advances in medical imaging instruments have increased their use considerably for diagnostics as well as planning and follow-up of treatment. Emerging from the fields of radiology, medical physics and engineering, medical imaging no longer simply deals with the technology and interpretation of radiographic images. The limitless possibilities presented by computer science and technology, coupled with engineering advances in signal processing, optics and nuclear medicine have created the vastly expanded field of medical imaging.

  • 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.

  • 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).

  • There are several reasons that may explain why the prevalence of heart failure is increasing: ageing of the population, the success in prolonging survival in coronary patients, and the success in postponing coronary events by effective prevention in those patients at high risk or those patients who have already survived a first event (secondary prevention) (Senni et al, 1999). Advances in medical therapy have resulted in improved survival in patients with moderate and severe heart failure, but the prognosis for end-stage heart failure patients still remains poor.

  • When good science makes an advance it pauses and turns to reacquaint itself with the modes of thought that immediately preceded it. Science orients itself with respect to these modes of thought, examines its connections, debts and disputes with them, decides whether it is operating at a different level of analysis and with respect to different interests, conceptualisations and subject matter. The present volume is a case in point of good science in this sense. It addresses medical pluralism, a founding concept of the field of medical anthropology.

  • Because of the availability of powerful computational techniques, new modality techniques such as Computer-Aided Tomography (CAT), Magnetic Resonance Imaging (MRI) and others, and because of the new techniques of imaging processing (machine vision), the lives of many patients will be saved, and the quality of all our lives improved. This marriage of powerful computer technology and medical imaging has spawned a new and growing generation of young dynamic doctors who hold PhDs in physics and/or computer science, along with their MDs.

  • The mathematical modeling of microstructures in solids is a fascinating topic that combines ideas from different fields such as analysis, numerical simulation, and materials science. Beginning in the 80s, variational methods have been playing a prominent rˆole in modern theories for microstructures, and surprising developments in the calculus of variations were stimulated by questions arising in this context.

  • Rapid technical advances in medical imaging, including its growing application to drug/gene therapy and invasive/interventional procedures, have attracted significant interest in close integration of research in life sciences, medicine, physical sciences and engineering. This is motivated by the clinical and basic science research requirement of obtaining more detailed physiological and pathological information about the body for establishing localized genesis and progression of diseases.

  • This book provides a review of image analysis techniques as they are applied in the field of diagnostic and therapeutic nuclear medicine. Driven in part by the remarkable sophistication of nuclear medicine instrumentation and increase in computing power and its ready and inexpensive availability, this is a relatively new yet rapidly expanding field. Likewise, although the use of nuclear imaging for diagnosis and therapy has origins dating back almost to the pioneering work of Dr G.

  • Modern medicine is characterized by the continuously growing spectrum of improving diagnostic methods and therapeutic processes. It keeps getting more complicated and confusing and therefore also needs more order. The main goal of medical documentation is to provide information for the adequate care of patients. Carefully carried out written records like a patient history, physician indexes, or, more recently, patient databases serve to reach this goal.

  • Introduction: β-Lactum antibiotics constitute an important class of antibacterial agents being used extensively for both humans and food-producing animals to treat or prevent infections. The drugs occasionally cause human deaths due to anaphylactic shock during medical treatments, especially when they are parenterally administered without their prior intracutaneous tests. These cases are usually handled as medical accidents (malpractice), and subjected to autopsies and analysis of the drugs used. These antibiotics are composed of cephems ( Table 10.1) and penicillins ( Table 10.

  • Ag-NPA-1 (AgFABP), a 15 kDa lipid binding protein (LBP) fromAscari-dia galli, is a member of the nematode polyprotein allergen/antigen (NPA) family. Spectroscopic analysis shows that Ag-NPA-1 is a highly ordered, a-helical protein and that ligand binding slightly increases the ordered sec-ondary structure content. The conserved, single Trp residue (Trp17) and three Tyr residues determine the fluorescence properties of Ag-NPA-1.
