Book Description
Gamma-Glutamyl Transpeptidases (γ-GTs) are members of the N-terminal nucleophile hydrolase superfamily, enzymes that cleave the γ-glutamyl amide bond of glutathione to liberate cysteinylglycine. The released γ-glutamyl group can be transferred to water (hydrolysis) or to amino acids or short peptides (transpeptidation). γ-GT plays a key role in the gamma glutamyl cycle by regulating the cellular levels of the antioxidant glutathione, hence it is a critical enzyme in maintaining cellular redox homeostasis.γ-GT is upregulated during inflammation and in several human tumors, and it is involved in many physiological disorders related to oxidative stress, such as Parkinson’s disease and diabetes. Furthermore, this enzyme is used as a marker of liver disease and cancer. This book covers current knowledge about the structure-function relationship of γ-GTs and gives information about applications of γ-GTs in different fields ranging from clinical biochemistry to biotechnology and biomedicine.​

Book Description
Much of the information currently available on the transport systems of bacterial and animal cell membranes and their mode of coupling to metabolic supply of energy can be found in this volume. Consideration of the participating enzymes dictated the choice of topics: Several transport systems where little information is available on the enzymology of the process are not included, while separate chapters deal with y-glutamyl transpeptidase and intestinal disaccharidases which meet many of the requirements of transport enzymes. The volume also includes two chapters on photosynthetic membranes as a general introduction to the topic. Other aspects of biological transport and photosynthesis will be developed in detail in a forthcoming volume now in preparation. These chapters reveal the excitement and rapid advance of the field, the daily reports of new concepts, new techniques, and new experimental findings which instantly interact to generate further progress. Our aim was to provide a starting point for those who are just beginning, and an opportunity for others to stop, take stock, and start in a new direction. My warmest thanks to all who contributed to this volume.

Book Description
This book, combining and updating two previous editions, is a unique source of information on the diagnosis, treatment, and follow-up of metabolic diseases. The clinical and laboratory data characteristic of rare metabolic conditions can be bewildering for both clinicians and laboratory personnel. Reference laboratory data are scattered, and clinical descriptions may be obscure. The Physician’s Guide documents the features of more than five hundred conditions, grouped according to type of disorder, organ system affected (e.g. liver, kidney, etc) or phenotype (e.g. neurological, hepatic, etc). Relevant clinical findings are provided and pathological values for diagnostic metabolites highlighted. Guidance on appropriate biochemical genetic testing is provided. Established experimental therapeutic protocols are described, with recommendations on follow-up and monitoring. The authors are acknowledged experts, and the book will be a valuable desk reference for all who deal with inherited metabolic diseases.

Book Description
This volume contains the proceedings of the XVth North American Testis Workshop, held in Louisville, Kentucky, April 7 to 10, 1999, to describe current advances in testis biology. The first two chapters provide a useful historical perspective of testis physiology and formulate compelling research questions about important aspects of sperm formation and function. This prologue sets the scene for the remainder of the volume that follows a logical progression, as the title implies, from stem cell to cell function, but that is necessarily preceded by sex determination, the quintessential requirement for there being a testis in the first place. The program for this XVth Testis Workshop evolved from recommenda tions of the scientific committee and their advice on the selection of invited speakers. The XVth Testis Workshop has a strong comparative flavor with contributions on worms (Caenorhabditis), flies (Drosophila), and chickens, which are models that permit and thereby reveal the power of genetic analy ses of the molecular mechanisms involved in spermatogenesis. A glimpse into the future is provided with information from EST, protein, and genome databases that already have an impact on progress in our understanding of the male germ cell. Although there is heavy emphasis in these chapters on cellular and molecular e,¥ents, database mining and translational profiling relevant to testis function and dysfunction and assisted reproduction tech nologies are not overlooked.
