Histochemical Studies Of The Liver Of The Rat During Embryonic Development Reprinted From The Journal Of Cellular And Comparative Physiology

This is the second edition of the third volume in the Monographs on Pathology of Laboratory Animals series. Since the first edition, new information has developed at a remarkable pace. Both editions propose standardized nomenclature that is being used internationally, gaining significant acceptance. The result is improved communications of pathologic data to regulatory agencies and in scientific publications worldwide. New information on the nature and variability of preneoplastic lesions in the liver of laboratory rodents is included in this edition. The book expands data on the accompanying changes in enzyme activity in affected liver cells. Spongiosis hepatis in the rat and its relation to spongiotic pericytoma are discussed thoroughly. Information on many other pathologic entities is brought up to date and new ones are added to this second edition, making it an even more useful and expanded reference text.

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a highly prevalent hereditary renal disorder in which fluid-filled cysts are appeared in both kidneys. Main causative genes of ADPKD are PKD1 and PKD2, encoding for polycystin-1 (PC1) and polycystin-2 (PC2) respectively. Those proteins are localized on primary cilia and function as mechanosensor in response to the fluid flow, translating mechanistic stimuli into calcium signaling. With mutations either of PKD1 or PKD2, hyper-activated renal tubular epithelial cell proliferation is observed, followed by disrupted calcium homeostasis and aberrant intracellular cyclic AMP (cAMP) accumulation. Increased cell proliferation with fluid secretion leads to the development of thousands of epithelial-lined, fluid-filled cysts in kidneys. It is also accompanied by interstitial inflammation, fibrosis, and finally reaching end-stage renal disease (ESRD). In human ADPKD, the age at which renal failure typically occurs is later in life, however no specific targeted medications are available to cure ADPKD. Recently, potential therapeutic targets or surrogate diagnostic biomarkers for ADPKD are proposed with the advances in the understanding of ADPKD pathogenesis, and some of them were attempted for clinical trials. Herein, we will summarize genetic and epi-genetic molecular mechanisms in ADPKD progression, and overview the currently available biomarkers or potential therapeutic reagents suggested.

Color Atlas of Fetal and Neonatal Histology serves as a comprehensive atlas of the developmental histology of the major organs from 15 weeks gestation to the neonatal period. Each section includes text on basic embryologic processes that influence the development of each organ and highlight major histologic features that correspond with certain developmental periods. In addition, there are many color photomicrographs at key developmental stages to assist the reader in identifying appropriate histologic changes at each developmental stage. This book will be of great value to students of embryology, pathology residents and fellows, and attending pathologists who perform fetal autopsies.

The first edition of Color Atlas of Fetal and Neonatal Histology was an important step in updating the histology texts available to practicing pathologists and pathology trainees who perform fetal autopsy and/or participate in research involving fetal tissues. It was a well-received volume that filled a major gap in pathology references related to normal histology and provided a comprehensive, state-of-the art review of fetal and neonatal histology. While the basics of fetal histology have changed little in the intervening years since publication of the first edition, this successor edition provides new insights and a fresh perspective. This book contains six new chapters including: blood vessels and lymphatics, external genitalia, eye, ear, skin, and maceration changes. Many existing chapters have also been expanded to address a greater breadth of fetal and neonatal histology such as postnatal testis development and the cardiac conduction system. The “Special Considerations” sections were also expanded in many chapters to address particularly problematic issues within individual organ systems. The book reviews the histology of the major organ systems in the fetus and neonate and provides detailed images, up-to-date references, and practical guidelines for identifying tissues across all gestational ages of development. The second edition of Color Atlas of Fetal and Neonatal Histology serves as the ultimate go-to resource for pathologists and researchers dealing with, and interested in, fetal and neonatal histology. It provides a comprehensive summary of the current status of the field with excellent and extensive illustrative examples that help guide the clinical study of fetal and neonatal histology and stimulate investigative efforts with fetal tissue.
