The meaning of biology is,'The science of life', which is derived from the Greek word bios (life), and logos (knowledge). So, Biology is the field of science dealing with Living Being. That's why Biology is also called Life Science. The book circumvents the customary human-centric style of nearly all introductory textbooks, the style which significantly misrepresents our understanding of the diversity of life. Our methodology focusses on the illustration of individual topics and their impact on different living species. For instance, the discussion of the cell-structure of different living things is present in the same chapter. The authors also highlight that it is essential to understand biological science as a whole for a thorough understanding of human biology. The book mainly avoids the use of specialized biological vocabulary where possible, instead it offers the concepts using simple English. This book is equally useful for readers from diverse backgrounds including researchers, professors, students, and biological scientists. Moreover, people having a background in other disciplines can also use this book to grasp the fundamentals of biology.

In eukaryotes, lipid metabolism requires the function of peroxisomes. These multitasking organelles are also part of species-specific pathways such as the glyoxylate cycle in yeast and plants or the synthesis of ether lipid in mammals. Proteins required for the biogenesis of peroxisomes typically assemble in large molecular complexes, which participate in membrane formation, protein transport, peroxisome duplication and - inheritance during cell division. Peroxisomal function is essential for life. Mutations in PEX genes, encoding for biogenesis factors, are often associated with lethal disorders. The association of peroxisomes with other organelles suggests an extensive participation in organellar crosstalk. This book represents a state-of-the-art review in the field of peroxisome research encompassing the cell and molecular biology of peroxisome biogenesis and its diseases, the protein complexes involved in this process and the modern technologies applied to study them. The book is intended for graduate students, researchers and lecturers in biochemistry, molecular and cell biology with a biomedical background.

Many modern geneticists attempt to elucidate the molecular basis of phenotype by utilizing a battery of techniques derived from physical chemistry on subcellular components isolated from various species of organisms. Volume 5 of the Handbook of Genetics provides explanations of the advantages and shortcomings of some of these revolutionary tech­ niques, and the nonspecialist is alerted to key research papers, reviews, and reference works. Much of the text deals with the structure and func­ tioning of the molecules bearing genetic information which reside in the nucleus and with the processing of this information by the ribosomes resid­ ing in the cytoplasm of eukaryotic cells. The mitochondria, which also live in the cytoplasm of the cells of all eukaryotes, now appear to be separate little creatures. These, as Lynn Margulis pointed out in Volume 1, are the colonial posterity of migrant prokaryotes, probably primitive bacteria that swam into the ancestral precursors of all eukaryotic cells and remained as symbionts. They have maintained themselves and their ways ever since, replicating their own DNA and transcribing an RNA quite different from that of their hosts. In a similar manner, the chloroplasts in all plants are self-replicating organelles presumably derived from the blue-green algae, with their own nucleic acids and ribosomes. Four chapters are devoted to the nucleic acids and the ribosomal components of both classes of these semi-independent lodgers. Finally, data from various sources on genetic variants of enzymes are tabulated for ready reference, and an evaluation of this information is attempted.

It is a “must” for libraries and the bookshelves of everyone interested in the biology of parasites and early-branching eukaryotes.

Les systèmes ubiquitine-protéasome et « ubiquitin-like » interviennent de manière concertée dans la régulation précise de toutes les fonctions cellulaires. Ils occupent ainsi une place centrale et transversale dans la biologie et leur manipulation à des fins cliniques promet de grandes avancées thérapeutiques. Il est primordial aujourd'hui, pour un biologiste, de connaître ces systèmes et de comprendre leurs mécanismes. Paradoxalement cependant, du fait des très nombreux domaines de la biologie dans lesquels ils interviennent, les informations sur ces derniers sont très dispersées dans la littérature, et il n'existe pas d'ouvrage récent décrivant de manière détaillée ces systèmes et leurs fonctions biologiques. Protéasome, ubiquitine et protéines apparentées à l'ubiquitine, vient combler ce manque en proposant pour la première fois, une synthèse en français des découvertes réalisées ces dernières années. Il est organisé autour de trois grands axes : - le premier est consacré à la description des machineries enzymatiques impliquées, en commençant par le système UPS (protéasome, enzymes d'ubiquitylation…) dont la découverte est historiquement à l'origine de tout ce champ d'investigations ; - le deuxième est constitué de chapitres « transversaux », dont la logique est de présenter comment les systèmes UPS et UBL interviennent dans la régulation de processus biologiques ou de voies de signalisation spécifiques ; - enfin, les derniers chapitres abordent les liens avec différentes pathologies humaines. Protéasome, ubiquitine et protéines apparentées à l'ubiquitine, est un ouvrage collectif, conçu dans un objectif didactique, il autorise de multiples points d'entrée, facilitant l'accès rapide aux informations précises pour un large public de biologistes. Le renvoi à de nombreux articles publiés dans des journaux internationaux permettra aux lecteurs qui le désirent d'approfondir leurs recherches.

Oxidative stress is the result of an imbalance in pro-oxidant/antioxidant homeostasis that leads to the generation of toxic reactive oxygen species. Brain cells are continuously exposed to reactive oxygen species generated by oxidative metabolism, and in certain pathological conditions defense mechanisms against oxygen radicals may be weakened and/or overwhelmed. DNA is a potential target for oxidative damage, and genomic damage can contribute to neuropathogenesis. It is important therefore to identify tools for the quantitative analysis of DNA damage in models on neurological disorders. This book presents detailed information on various neurodegenerative disorders and their connection with oxidative stress. This information will provide clinicians with directions to treat these disorders with appropriate therapy and is also of vital importance for the drug industries for the design of new drugs for treatment of degenerative disorders.• Contains the latest information on the subject of neurodegenerative disorders• Reflects on various factors involved in degeneration and gives suggestions for how to tackle these problems

Ultrastructure in Biological Systems, Volume 2: Ultrastructure of the Kidney provides an overview of the state of knowledge on the ultrastructure of the mammalian kidney. The application of the electron microscope to studies of the kidney resulted in the demonstration of the hitherto undetected early thickening of the basement membrane of glomerular capillaries in glomerulonephritis. Yet many problems remain, particularly in relation to the correlation between function and the ultrastructure of components of the kidney—mesangium, glomerulus, juxtaglomerular apparatus, and the renal tubules. It is only recently that the mesangium has come to be accepted as real, and many questions remain as to the function of its cells. The existence of true membranes between foot processes of the epithelial cells of glomeruli is a newly established fact; but what this has to do with glomerular filtration is not known at present. Granules apparently secretory in nature have been identified in cells of the juxtaglomerular apparatus, but so far their presence has not been correlated with specific functional change. Artifacts introduced at fixation are now known to have considerable relevance in interpreting the ultrastructure of the normal nephron. These are paraphrased views of the contributors to this monograph who, while acquainting the reader with the research being carried on in these areas, have also brought into focus the many problems still awaiting solution.

Connective tissues known as osteoblasts and odontoblasts produce bone/cartilage and teeth. One author examines the biochemistry and pathology of the connective tissue of the periodontium that is related to periodontal disease. He also examines the role of oral bacteria in the pathogenesis of periodontitis; he concludes that bacterial enzymes can increase permeability for other bacterial types to directly elicit inflammation. One author analyzes the physical chemistry of gelatin and gelatin transition. He concludes that the rate of fold formation and the stability of the fold-units on single-chain gelatins and on multichain gelatins depend on the relative effectiveness of ions. Single-chain gelatins have the highest rate of network junction point formation; multichain gelatins, with enhanced cyclic junction point formation, have less network-forming properties. Cellular biologists, pathologists, physiologists, gerontologists, and researchers in gene therapy, pharmacology, micro- or molecular chemistry will find this book highly informative.
