Tranformations in the Facial Region of the Human Embryo
ISBN: 9783540060888 / Angielski / Miękka / 32 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The human face is invariably interesting, even as an object of embryologic analysis. The early embryonic growth processes are located around the developing sense organs, among which the nose holds a key position. The first indication of the development of the nose is the formation of the placodes, oval areas of thick- ened and condensed ectoderm, one on each side of the head. Each of these placodes is transformed, via the nasal groove, into the nasal tube, sometimes indicated as primitive nasal cavity. In the literature this transformation has been described as an isolated process that...

Heavy Metals in the Brain: A Light Microscope Study of the Rat with Timm's Sulphide Silver Method. Methodological Considerations and Cytological
ISBN: 9783540062134 / Angielski / Miękka / 71 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The importance of transition metals and group II b metals in biological reac tions is becoming increasingly clear. Such metals form an integral part of the structure of many enzymes and non-enzymic proteins and also feature in more reversible interactions between metal ions and large or small biological molecules (Johnson and Seven, 1961). As discussed at the end of this paper, chemical analyses have shown the presence of these metals in the central nervous system and some hypotheses have been advanced concerning their role in more specific nervous activities such as synaptic processes. In...

Structure Function Correlation on Rat Kidney: Quantitative Correlation of Structure and Function in the Normal and Injured Rat Kidney
ISBN: 9783540110743 / Angielski / Miękka / 108 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Over the past few decades an exceedingly large number of experimental and clinical investigations have been performed in an attempt to analyze the way in which the kidney functions. The basis for all this work was established during the nineteenth and the early twentieth century by morphologists (Bowman 1842; Hyrtl1863, 1872; Heidenhain 1874; Peter 1909; von Mollendorf 1930). All these investigators clearly outlined the extremely heterogeneous assembly of renal tissue and also defined the nephron as the smallest morphological unit. It was further the merit of these anato- mists and...

Methylotrophy and Methanogenesis
ISBN: 9780442305284 / Angielski / Miękka / 88 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This short book attempts to give a reader who has a basic biochemical and microbiological background (one to two years at University level) an idea of the ecological, biochemical, physiological and biotechnological importance of methane, methanol and related compounds in the microbial world. Because the book covers several different scientific disciplines, readers may encounter unfamiliar terminology. The glossary at the end of the book defines the more obscure of these. The book has been written during a period of heavy teaching commit ments, and despite the helpful comments of many...

Uv-B and Biosphere
ISBN: 9780792344223 / Angielski / Twarda / 313 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Current phase-out schedules of the production and emission of CFC's indicate that chlorine loading in the stratosphere is not yet at its maximum. The recovery of stratospheric ozone is estimated to take time and ele- vated levels of UV-B radiation are expected to occur throughout most of the next century. Despite numerous physiological studies of UV-B effects on plants, often grown in climate chambers, knowledge of UV-B effects on organisms and processes in natural aquatic or terrestrial ecosystems is poor. Currently it appears that UV-B radiation is not just an environmental stress' factor...

Model Experts: Wax Anatomies and Enlightenment in Florence and Vienna, 1775-1815
ISBN: 9780719082054 / Angielski / Twarda / 264 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Based on a detailed study of rich archival sources, Model experts explores practices of model production and display, and reveals the often invisible labours of the co-operating artisans, anatomists, and administrators.
The book shows that the models were central to a remarkable political experiment: 'La Specola' opened in 1775 as the Royal Museum of Physics and Natural History, one of the first public science museums in Europe. As a venue for public enlightenment, the museum displayed model anatomies to create the model citizen. The study also moves beyond the borders of Tuscany,...

Proliferation of Different Cell Types in the Brain
ISBN: 9783540098997 / Angielski / Miękka / 74 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Studies on cell kinetics in untreated animals have for the most part been done on or- gans in which many proliferating cells can be found. In general the proliferating cells have been identified either in histologic sections as mitoses or by autoradiography as labeled interphase cells following the injection of a labeled precursor of DNA, such as 3H_ or 14C-thymidine (TdR). A great many proliferating cells can be observed in the rat and mouse brain during the embryonic period and for a short time after birth, and many studies on cell kinetics have been performed for this phase of life. By...

In 1953, at the grand age of 92, Ferdinand Hochstetter submitted his famous collection of photographs of human embryos entitled: "Uber die Entwicklung der Formverhaltnisse des menschlichen Antlitzes." Together with others papers, this contribution was published in 1955, a year after Hochstetter's death. In unbroken combativeness, Hochstetter discussed his results with regard to those of earlier embryologists and to those of his own lifetime. Thus, in an obituary, Elze (1956) reported about one of Hochstetter's letters from the year of his death (1954): "nur einige blodsinnige Behauptungen,...

Mechanical Stress, Functional Adaptation and the Variation Structure of the Human Femur Diaphysis
ISBN: 9783540054641 / Angielski / Miękka / 90 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. According to the classical theory of functional structure of bone which was developed by J. Wolff (1884, 1892) and W. Roux (1895) following the investigations of the functional architecture of the substantia spongiosa by H. von Meyer (1867), bone is "functionally" laid down in gross form as well as in minute architecture in accordance with the "maximum-minimum-law". As a result of functional adaptation, a maximum of efficiency is achieved with a minimum of material (Kummer, 1962a). In this sense functional adaptation is a reaction of adaptation of the idiotype-within the bounds of the...

Biochemical studies on plant virus RNA replication have advanced considerably since 2000, primarily because of new genetic, molecular, biochemical, and enzymatic studies. This book generates understanding of multiplication of plus-sense RNA plant viruses, especially at molecular level. Certain virus-encoded essential proteins, nucleotide sequence motifs, and RNA secondary structures are central to virus RNA replication, which has a number of stages. Each is a complex phenomenon requiring specific factors and conditions.

This textbook focuses on stochastic analysis in systems biology containing both the theory and application. While the authors provide a review of probability and random variables, subsequent notions of biochemical reaction systems and the relevant concepts of probability theory are introduced side by side. This leads to an intuitive and easy-to-follow presentation of stochastic framework for modeling subcellular biochemical systems. In particular, the authors make an effort to show how the notion of propensity, the chemical master equation and the stochastic simulation algorithm arise as...
