Biochemistry and Physiology of Nutrition, Volume II focuses on the processes, methods, and studies on nutrition. The book starts by discussing intracellular localization through histochemical methods of enzymes and vitamins; the structural changes in vitamin deficiency; and microbiology of digestion. Deficiencies in vitamins, A, C, D, E, B1, riboflavin, nicotinic acid, choline, biotin, and folic acid are noted. The book then focuses on microbiology of digestion, considering the establishment of microbial population in the alimentary tract, results of microbial digestion, antibiotics, and intestinal flora of man. The text also defines the nutrition system of worms, insects, and protozoa. The generation of ATP in terminal respiration and anaerobic glycolysis, as well as ATP's role in energy transfer, is noted. The discussions also focus on hydrolytic and phosphorylitic enzymes, such as carbohydrates, esterases, amidases, phosphatases, and phosporylases. Other topics covered are respiratory enzymes and coenzymes in which nucleotides, glucose diphosphate, diphosphoglyceric acid, and thiamine pyrophosphate are noted. The book notes the functions of iron compounds in the body, particularly in blood and tissues, and then touches on calcium and phosphorus metabolism. Given considerations are calcium and phosphorus in blood, skeletal calcium and phosphorus, and the factors affecting adsorption. A discussion also focuses on trace elements and the effects of protein, carbohydrates, fats, and vitamins in nutrition. The book is a vital source of data for readers interested in studying the elements, factors, processes, and methods involved in nutrition.

Keeping and Breeding Aquarium Fishes deals with the aquarium as a going concern, on the factors which enter into the maintenance of this state, and on fish breeding. Cold-water and goldfish enthusiasts may complain that the tropicals seem to get an overweight share of the text. This is because they need it. This book is not concerned with fancy varieties or show standards, except so far as they need special conditions for maintenance or breeding. The book opens with a chapter on the elements of a balanced aquarium, covering tanks, plants, and aquarium snails. This is followed by separate chapters on anatomy and physiology of fishes, fish foods and feeding, the principles of aquarium keeping, the process of setting up a tank, lighting and heating; and the aeration, filtration, and circulation of the water. Subsequent chapters deal with and aquarium rooms with breeding batteries; the breeding of livebearers, egg scatterers, anabantids, and cichlids; types of fish disease, and keeping saltwater fishes.

The Action of Hormones in Plants and Invertebrates focuses on the mechanisms of action of hormones in plants and invertebrates, including auxins, vitamins, steroids, and carotenoids. The book considers plant growth hormones, hormone-like substances in fungi, and hormones in insects and crustaceans. This volume is organized into four chapters and begins with a historical overview of the concept of hormones in plants, and then describes assay methods for auxins, along with auxin chemistry, transport, and role in tropisms. The discussion moves to other plant hormones such as wound hormones, flower-forming hormones, vitamins, steroids, carotenoids, rhizocaline, and caulocaline. The book then methodically explains insect hormones and their sources; the role of hormones in reproduction and postembryonic development; and hormone-induced color change in insects. This volume also offers information on the mode of action and physicochemical properties of insect hormones. The book concludes with a chapter on the biological effects of hormones on Crustacea, from sex characteristics to color change, molting and growth, retinal pigment movements, locomotion, and ovarian development. This book will be of interest to biologists, zoologists, botanists, and endocrinologists.

Methods in Food Analysis Applied to Food Products deals with the principles and the acquired tools of food analysis, emphasizing fruit and vegetable products. The book explains the suitability and limitations of the analytical procedures used for food products, from polarimetry and saccharimetry to colorimetry, spectrophotometry, viscosimetry, acidimetry, and alcoholometry. This volume is organized into 20 chapters and begins with an overview of sampling and preparation and preservation of sample. Under the physical methods, the principles of the more common procedures are discussed together with their application to the analysis of fruit and vegetable products. A brief account of the nature of the products is included. In presenting the chemical methods, the salient chemical properties of the constituent are first considered, focusing on those properties used in analysis, which is then followed by an outline of the chemistry of several of the available methods. Finally a detailed description of one of the methods, usually as applied to fruit and vegetable products, is explained. Some references to microanalytical, bioassay and bacteriological procedures are made. This book is intended for food technologists, chemists, and manufacturers; students; and researchers involved in quantitative analyses; organic and inorganic chemistry; and bacteriology.

The Hormones: Physiology, Chemistry and Applications, Volume II covers the chemistry, physiology, and clinical applications of the mammalian endocrinology. This volume contains 10 chapters, and begins with discussions on the physiology and the role of ovarian hormones and androgens on vital processes. The subsequent chapters explore the biochemistry, physiology, and metabolism of specific secreted hormones, such as adrenal cortex, thyroid, and posterior pituitary hormones, and gonadotrophins. Other chapters deal also with the chemical control of nervous activity of acetylcholine, adrenaline, sympathin, and neurohormones. The concluding chapter focuses on the clinical applications of the covered hormones and their role in mammalian growth. This book is an invaluable source for mammalian endocrinologists, physiologists, biochemists, and researchers who are interested in mammalian development.
