In Volume 18 of this well-established series, Professor Atta-ur-Rahman again brings together the work of several of the world's leading authorities in organic chemistry. Their contributions demonstrate the rapid, ongoing development of this field by illustrating many of the latest advances in synthetic methods, total synthesis, structure determination, biosynthetic pathways, and biological activity.The opening chapter presents an overview of strategies for the synthesis of several classes of natural products with an emphasis on complex polycyclic systems. Subsequent chapters discuss the synthesis of specific classes of compounds, including morphine, polyketides, acetogenins, nonactic acid derivatives, complex spirocyclic ethers, ä-lactam and pyridone derivatives, inositol phosphates, sphingolipids, brassinosteroids, Hernandia lignans, and dimeric steroidal pyrazine alkaloids. Finally, the ever stronger links between chemistry and biology are reinforced by chapters on the origin and function of secondary metabolites, bioactive conformations of gastrin hormones, and immunochemistry.
Abstract: Plexiform neurofibromas occurring in approximately 20-50% of all neurofibromatosis type-1 (NF1) cases are histologically benign tumors, but they can be fatal due to compression of vital structures or transformation to malignant sarcomas or malignant peripheral nerve sheath tumors. All sizeable plexiform neurofibromas are thought to result from an early second mutation giving rise to a loss of heterozygosity of the NF1 gene. In this unusual case, a 12-year-old girl presented with a rapidly growing, extremely extensive plexiform neurofibroma with segmental distribution over the entire right arm, extending to the right chest wall and mediastinum, superimposed on classic cutaneous lesi...
Genomics and Health in the Developing World provides detailed and comprehensive coverage of population structures, human genomics, and genome variation--with particular emphasis on medical and health issues--in the emerging economies and countries of the developing world. With sections dedicated to fundamtals of genetics and genomics, epidemiology of human disease, biomarkers, comparative genomics, developments in translational genomic medicine, current and future health strategies related to genetic disease, and pertinent legislative and social factors, this volume highlights the importance of utilizing genetics/genomics knowledge to promote and achieve optimal health in the developing worl...
Foreword, written by Alexander A. Di Lella appears after "Contents" and a photo of the honoree; then, Introduction, by the editors. The contributions, thirteen in all, are divided into four parts: One: Genesis Creation Traditions; Two: Later Septuagintal Books; Three: New Testament Texts; and Four: Linguistic Studies. Next there is a bibliography of Fr. Gignac; a list of the contributors, with their academic locations; Index of Ancient Sources; Index of Authors; Index of Subjects.
