This book was released on 2019 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: We present a taxonomic revision of the Colombian Tityus (Archaeotityus) species based on morphological and morphometric evidence. We examined more than 385 specimens and evaluated new and previously used qualitative and quantitative morphological characters. We redescribe the Colombian species and present morphological characters for both sexes and an emended diagnosis for the subgenus Tityus (Archaeotityus). We describe a new species Tityus guane sp. nov. from Santander department, Colombia, Tityus betschi Lourenço 1992 is synonymized with Tityus parvulus Kraepelin, 1914, and Tityus wayuu Rojas-Runjaic & Armas, 2007 is synonymized with Tityus tayrona Lourenço, 1991. We measured 186 specimens and performed a multivariate principal component analysis (PCA) for 34 selected morphometric ratios for each sex. We found that a few morphological ratios support species level distinctions within the Colombian species. We provide updated distributional maps with new records and an identification key for both sexes. Furthermore, we provide an updated checklist for the subgenus and a discussion about the character systems used within Tityus (Archaeotityus). The new morphological characters proposed and the traditional morphometry examined with a PCA are useful for studying Tityus (Archaeotityus) taxonomy. Keywords: Arachnida, Scorpions, South America, Neotropical region, Scorpiones"--Page 3.
Download or read book Scorpion Venoms written by P. Gopalakrishnakone and published by Springer. This book was released on 2021-01-14 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the field of Toxinology has expanded substantially. On the one hand it studies venomous animals, plants and micro organisms in detail to understand their mode of action on targets. While on the other, it explores the biochemical composition, genomics and proteomics of toxins and venoms to understand their three interaction with life forms (especially humans), development of antidotes and exploring their pharmacological potential. Therefore, Toxinology has deep linkages with biochemistry, molecular biology, anatomy and pharmacology. In addition, there is a fast developing applied subfield, clinical toxinology, which deals with understanding and managing medical effects of toxins on human body. Given the huge impact of toxin-based deaths globally, and the potential of venom in generation of drugs for so-far incurable diseases (for example, Diabetes, Chronic Pain), the continued research and growth of the field is imminent. This has led to the growth of research in the area and the consequent scholarly output by way of publications in journals and books. Despite this ever growing body of literature within biomedical sciences, there is still no all-inclusive reference work available that collects all of the important biochemical, biomedical and clinical insights relating to Toxinology. The Handbook of Toxinology aims to address this gap and cover the field of Toxinology comprehensively.

Download or read book Animal Diversity and Biogeography of the Cuatro Ci negas Basin written by Fernando Álvarez and published by Springer. This book was released on 2019-05-09 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume investigates the contemporary fauna that inhabit the Cuatro Ciénegas Basin. Divided into 15 chapters, it addresses and describes their diversity, taxonomic and biogeogaphic affinities, and ecological characteristics. The Cuatro Ciénegas Valley is a unique oasis in the south-central region of the State of Coahuila, part of the Sonoran Desert, in Mexico. Several clues, specially derived from the study of the microbiota, suggest a very ancient origin of the valley and its permanence through time. This condition had promoted a high level of endemism and led to unique interactions between the resident species.

Download or read book Handbook of Venoms and Toxins of Reptiles written by Stephen P. Mackessy and published by CRC Press. This book was released on 2021-05-24 with total page 912 pages. Available in PDF, EPUB and Kindle. Book excerpt: A decade after publication of the first edition, Handbook of Venoms and Toxins of Reptiles responds to extensive changes in the field of toxinology to endure as the most comprehensive review of reptile venoms on the market. The six sections of this new edition, which has nearly doubled in size, complement the original handbook by presenting current information from many of the leading researchers and physicians in toxinology, with topics ranging from functional morphology, evolution and ecology to crystallography, -omics technologies, drug discovery and more. With the recent recognition by the World Health Organization of snakebite as a neglected tropical disease, the section on snakebite has been expanded and includes several chapters dealing with the problem broadly and with new technologies and the promises these new approaches may hold to counter the deleterious effects of envenomation. This greatly expanded handbook offers a unique resource for biologists, biochemists, toxicologists, physicians, clinicians, and epidemiologists, as well as informed laypersons interested in the biology of venomous reptiles, the biochemistry and molecular biology of venoms, and the effects and treatment of human envenomation.

Book excerpt: An "Identification Manual" on the Amazonian Entomofauna for beginners and non-specialists has been demanded for many years. Most taxonomic literature on Neotropical Arachnida and Myriapoda is strictly descriptive, keys in translated and accepted textbooks are restricted to the higher taxa and first introductions to Amazonian arthropods refer to specific sampling sites and are mainly devoted to insects. And the other hand, taxonomical knowledge on Amazonian Arthropoda was much improved due to investigations for the last two decades, cooperatively between the National Institute for Amazonian Research and the Tropical Ecology Working Group at the Max-Planck-Institute for Limnology in Ploen/Germany

Download or read book Evaluation of Enzyme Inhibitors in Drug Discovery written by Robert A. Copeland and published by John Wiley & Sons. This book was released on 2005-04-01 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vital information for discovering and optimizing new drugs "Understanding the data and the experimental details that support it has always been at the heart of good science and the assumption challenging process that leads from good science to drug discovery. This book helps medicinal chemists and pharmacologists to do exactly that in the realm of enzyme inhibitors." -Paul S. Anderson, PhD This publication provides readers with a thorough understanding of enzyme-inhibitor evaluation to assist them in their efforts to discover and optimize novel drug therapies. Key topics such as competitive, noncompetitive, and uncompetitive inhibition, slow binding, tight binding, and the use of Hill coefficients to study reaction stoichiometry are all presented. Examples of key concepts are presented with an emphasis on clinical relevance and practical applications. Targeted to medicinal chemists and pharmacologists, Evaluation of Enzyme Inhibitors in Drug Discovery focuses on the questions that they need to address: * What opportunities for inhibitor interactions with enzyme targets arise from consideration of the catalytic reaction mechanism? * How are inhibitors evaluated for potency, selectivity, and mode of action? * What are the advantages and disadvantages of specific inhibition modalities with respect to efficacy in vivo? * What information do medicinal chemists and pharmacologists need from their biochemistry and enzymology colleagues to effectively pursue lead optimization? Beginning with a discussion of the advantages of enzymes as targets for drug discovery, the publication then explores the reaction mechanisms of enzyme catalysis and the types of interactions that can occur between enzymes and inhibitory molecules that lend themselves to therapeutic use. Next are discussions of mechanistic issues that must be considered when designing enzyme assays for compound library screening and for lead optimization efforts. Finally, the publication delves into special forms of inhibition that are commonly encountered in drug discovery efforts, but can be easily overlooked or misinterpreted. This publication is designed to provide students with a solid foundation in enzymology and its role in drug discovery. Medicinal chemists and pharmacologists can refer to individual chapters as specific issues arise during the course of their ongoing drug discovery efforts.
