Download or read book Placental Pharmacology written by B. V. Rama Sastry and published by CRC Press. This book was released on 1996-05-06 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Placenta plays a very significant role in the development of secretory and regulatory functions for the maintenance of pregnancy and in the nutrition of the embryo. It shares many functions of the heart, lung, liver, endocrines, and other organs. In Placental Pharmacology, fourteen expert authors discuss how placenta and its component parts can be used effectively in drug development research and in the study of transfer mechanisms across membranes. This reference begins by describing the use of modern biophysical methods to study placental function and prospects for their application in pharmacological research. The next three chapters deal with placental hemodynamics, use of placental tissues and cells in pharmacological assays, and placental transfer of drugs used in pregnancy. Three more chapters contain up-to-date information on molecular biological aspects of placenta currently receiving lots of attention - phospholipase A2 isozymes, imprinted genes and embryogenesis, and placental growth factors. The final chapter describes the clinically relevant topics of placental metabolism and toxicity of homocysteine in placenta. Easy to understand, thorough, and complete, Placental Pharmacology is the perfect resource for scientists interested in placenta and its uses in drug development and testing.

Download or read book Teratogenesis and Reproductive Toxicology written by E.M. Johnson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resolution of links between exposure to components of our complex environmental and causation of reproductive effects in the population constitutes an important problem in the field of toxicology. The focus of this volume is developmental toxicology, which represents one aspect of reproductive toxicology dealing with the study of adverse effects on the developing conceptus. Developmental toxicology, which includes teratogenesis as one of its manifesta tions, provides a fertile field for research in several basic and clinical disciplines; this field also receives input from several disoiplines such as developmental and molecu lar biology, pathology, pharmacology and toxicology, pediatrics and neonatology, and epidemiology. More recently we h~ve seen an emergence of interest in other fields such as perinatal physiology and postnatal behavior which have now become incorporated into the mainstream of research in this discipline. The present volume is an effort to provide a sampling of concepts currently under active investigation in several of the above fields. The authors have endeavored to provide up-to-date in formation on the following topics: detection and analysis of potential hazards to the conceptus in the workplace, pharmacokinetic aspects of the maternal/placental! fetal complex and its relationship to human birth defects, and probable mechanisms of teratogenesis as uncovered in certain well-defined situations. Also included are summaries of newer investigations on the emerging field of postnatal functional evaluations, i. e. , adverse effects on adult activities resultant from in utero exposure to toxic substances.

Download or read book Toxicology and the Maternal fetal Environment written by Teresa Dodd-Butera and published by . This book was released on 2008 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Placental function is paramount to maintaining optimum conditions both in utero and for long term fetal development. Glutathione-S-transferases (GSTs) play a role in the placenta by protecting the fetus from toxicants and oxidative stress. A soluble form of GST, GST pi (GSTP1), accounts for a significant amount of placental GST enzyme activity. Previous studies indicate that the Ile105Val polymorphism in GSTP1 affects susceptibility to pathologic conditions of pregnancy such as preeclampsia and recurrent pregnancy loss. GSTP1 also detoxifies environmental carcinogens such as polyaromatic hydrocarbons (PAHs). This study investigates the relationship between placental levels of GST pi, enzyme activity, and genetic polymorphisms of biotransformation enzymes CYP1A1 exon 7, GSTP1, GSTM1; and PAH-DNA adduct measurements. Maternal venous and umbilical cord blood and placental tissue were collected from 54 consenting obstetric patients from Tijuana, Baja California (BC), Mexico (maternal age mean 25.8, range 16--39 years). Placental GST pi levels were measured via Western blots; GST activity was measured against CDNB; and genetic polymorphisms were assessed by PCR and restriction enzyme digestion. Relative adduct levels were obtained by 32P-postlabeling. A 30-fold variation in enzyme activity was found and activity ranged from 21--623 nmol/min/ml. Activity and levels of GSTPi were modestly correlated (r = 0.359, p = 0.13). No difference was found in placental GSTPi activity associated with the GSTP1 Ile105/Ile105 genotype vs. the Val105/Val105 genotype. An increased activity was however observed in placental supernatant from GSTP1 Ile105 positive mother/baby pairs that were concordant for GST mu negative genotype vs. pairs with GST mu positive genotype, though numbers were very small (n = 6 vs. n = 31, p = 0.024); median PAH-DNA adduct measurements were 10.4 RAL x 109 nucleotides. Placental variability in levels and activity of the protective enzyme GST pi can be substantial between Hispanic women. GST pi levels and genetic variation at GSTP1 ile105val does not appear to explain variability in placental enzyme activity and PAH-DNA adduct measurements. Further studies are necessary to elucidate the impact of placental biotransformation enzymes on pregnancies which are more at risk from endogenous and environmental toxicants.

Download or read book Toxicology of Organophosphate and Carbamate Compounds written by Ramesh C Gupta and published by Academic Press. This book was released on 2011-04-28 with total page 781 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text/reference book provides the most comprehensive coverage of anticholinesterase compounds (Organophosphates and Carbamates), which constitute the largest number of chemicals that are primarily used as insecticides in agriculture, industry, and around the home/garden. Some OPs (nerve agents) have been used in chemical warfare and terrorist attacks, while some OPs and CMs have been recommended as therapeutic agents in human medicine as well as in veterinary medicine. Many chemicals of both classes are extremely toxic and lack selectivity, thus their inadvertent/accidental use continues to pose a threat to human and animal health, aquatic systems and wildlife. These anticholinesterase agents produce a variety of toxicological effects in target and nontarget organs. In light of this complexicity, this multi-authored book is written by the well known scientists from many countries. The book is organized into nine sections, with a total of 49 chapters, to provide in-depth knowledge on various aspects of OP and CM compounds, including their use, classification, mechanism-based toxicity, and prophylactic and therapeutic measurements. Several chapters are written with special emphasis to cover timely topics, such as chemical warfare agents, physiologically-based pharmacokinetic modeling, structure and function of cholinesterases, paraoxonase, carboxylesterases; developmental neurotoxicity, the intermediate syndrome, oxidative stress, endocrine disruption, and DNA damage/gene expression and carcinogenesis. Section-VI with 5 chapters is specifically devoted to risk assessment, and safety and regulatory guidelines for pesticides. Describes everything you need to know about Organophosphates and Carbamates Extensively covers pesticides, nerve agents, therapeutic drugs, and flame retardants Describes epidemiology of the world's major disasters involving Organophosphates and Carbamates Covers animal, human, aquatic, and wildlife toxicity of Anticholinesterases Insights into in-depth cholinergic and noncholinergic mechanisms of toxicity Describes recent advancements in cholinesterases, paraoxonases, carboxylesterases, oxidative stress, endocrine disruption, cardiac and pulmonary toxicity, and carcinogenesis Provides in vitro and in vivo models for neurotoxicity testing Integrates knowledge of studies in lab animals and humans Offers risk/safety assessment and national/international guidelines for permissible levels of pesticide residues Describes management of Anticholinesterase poisoning in humans
