Membrane Transport: A Practical Approach
Manufacturer: Oxford University Press, USA ProductGroup: Book Binding: Paperback ASIN: 0199637040 |
Book Description
Membrane Transport is targeted towards researchers with an interest in the mechanism of solute transport across biological membranes. Its scope is broad, ranging from the techniques required to study transport itself, through the expression, purification and reconstitution of transporters, to techniques for investigation of their structures. As such, it not only proves the necessary technical grounding for newcomers to the field, but should also be of value to "old-hands" wishing to get up to date with recent developments in these areas. While some of the approaches described require sophisticated equipment (e.g. a stopped-flow fluorimeter), most of the protocols can be implemented in any well- found laboratory. Preparation of this volume comes at a time when a result of genome sequencing our knowledge of membrane transporter sequences is far outstripping our understanding of their molecular mechanisms. Our hope is that this book will help future researchers to redress this imbalance.

Moving Questions: A History of Membrane Transport and Bioenergetics
Joseph D. Robinson Manufacturer: An American Physiological Society Book ProductGroup: Book Binding: Hardcover ASIN: 0195105648 |
Book Description
This book describes half a century of progress in two mainstream areas of biological research: membrane transport, initially a focus of physiologists, and oxidative phosphorylation, initially a focus of biochemists. Robinson shows how the development of new explanatory models had unexpectedly merged these inquiries into a new field, bioenergetics. In the late 1930s, explanations for the asymmetric distribution of ions between cells and their environments invoked absolute impermeabilities of the cell's surrounding membranes. But new experiments contradicted that idea and demonstrated that forming the transmembrane distributions required metabolic energy, implying the participation of active transport "pumps." Subsequent studies identified, isolated, and characterized these pumps as enzymes coupling ionic transport to the consumption of adenosine triphosphate (ATP), an "energy-rich" molecule serving as a cellular energy store. In the late 1930s oxidative phosphylation, the process of coupling ATP synthesis to oxidative metabolism, was identified. The explanatory model emerging in the next decades, however, did not follow the enzymatic precedents of known metabolic phosphorylations but rather embodied the principle that metabolic oxidations drive active transport pumps to create transmembrane distribution of ions, with these ionic asymmetries then driving ATP synthesis. It was discovered that ATP consumption can form ionic asymmetries; ionic asymmetries can drive ATP formation; and ionic asymmetries-like ATP-can also power other cellular functions.

Regulatory Mechanisms of Intracellular Membrane Transport (Topics in Current Genetics)
Manufacturer: Springer ProductGroup: Book Binding: Hardcover ASIN: 3540223029 |
Book Description
This book deals with the molecular mechanisms of membrane trafficking, a central eukaryotic cell biological process. In the post-genomic era many essential molecules involved in intracellular membrane/protein transport are emerging. A huge task now is to compile the molecular networks that govern these processes. Understanding of regulatory processes and participating molecules are likely to reveal global cellular regulatory circuits that couple membrane trafficking with other cellular functions. Such cell biological features are only starting to emerge. This book puts special emphasis on such mechanisms and processes. The contents discusses the role of coat proteins, tethering complexes, small rab GTPases, Sec1-family proteins and SNARE molecule phosphorylation in exocytosis, endocytosis and membrane fusion. In addition, the role of lipids in vesicle formation and membrane fusion, and some specialized cell biological denovo membrane generation processes are discussed.

ASIN: 0387985891 |
Book Description
Superstrings and M-theory: provocative and controversial, but unarguably one of the most interesting and active areas of research in current physics. Called by some, "the theory of everything," superstrings may solve a problem that has eluded physicists for the past 50 years, the final unification of the two great theories of the twentieth century, general relativity and quantum field theory. Now, here is a thoroughly revised, second edition of a course-tested comprehensive introductory graduate text on superstrings which stresses the most current areas of interest, not covered in other presentations, including: · Four-dimensional superstrings · Kac-Moody algebras · Teichmüller spaces and Calabi-Yau manifolds · M-theory Membranes and D-branes · Duality and BPS relations · Matrix models The book begins with a simple discussion of point particle theory, and uses Feynman path integrals to unify the presentation of superstrings. It has been updated throughout, and three new chapters on M-theory have been added. Prerequisites are an acquaintance with quantum mechanics and relativity.Customer Reviews:
a "schaum's outline" of string theory.......2004-02-21
Helpful in some places.......2003-08-16
One of the places which it does this is in chapter 5 on multiloops and Teichmuller spaces. The author discusses the Schottky groups, the constant curvature metric formalism, theta functions, and the light cone formalism, the latter of which is dealt with in the context of string field theories in later chapters. The author points out the Schottky problem as one that has been solved and its connection to the parametrizing moduli space by the period matrix for the calculation of loop amplitudes beyond three loops. He does a good job of explaining how to calculate the multiloop amplitude using these different formalisms, particularly the origin of the "period matrix". An explicit formula is given for the multiloop amplitude in terms of the Schottky groups using the Nambu-Goto formalism. The functional integral does not fix uniquely the region of integration in this formalism, and so this region must be carefully truncated to avoid overcounting. This motivates the author to introduce the Polyakov formalism, which, interestingly, makes heavy use of the research of the 19th century on Riemann surfaces. Thus, string theory should not be thought of as a purely 21st century theory that found its way into the 20th, as some have described it. Much of the mathematics it uses comes from the latter half of the 19th century. The author shows how the singularity structure of the multiloop diagram can be expressed in terms of a Selberg zeta function. The redundancy in the path measure under conformal transformations is removed by gauge fixing, Weyl rescalings, and reparametrizations. All of this leads to the moduli space of constant curvature metrics so as to alleviate the problem of overcounting from reparametrization invariance. The moduli space, as usual, is written as Teichmuller space modulo the mapping class group, and the author shows how to relate the variation of the metric tensor to the quadratic differentials. All of these considerations are then generalized to superstrings, with the author showing how the presence of spinors complicates things to a certain extent. The author does mention the supermoduli space in connection with Grassmannians, but unfortunately refers the reader to the literature for further details. He justifies his avoidance of the Grassmannian approach by purusing a field theory of strings. The latter however is just as complicated, although for different reasons.
Another helpful discussion in the book is the one on Kac-Moody algebras and E8. The author motivates well the need for Kac-Moody algebras, namely that of making sense of the complicated spectrum of the heterotic string. The Kac-Moody algebras are first developed in the book in the context of conformal field theory wherein the author introduces the famous vertex operators. In the case of heterotic strings, the author uses the vertex operators to construct a representation of a Kac-Moody algebra that utilizes the Chevalley basis.
The discussion on F-theory, although very short, is also very interesting and helpful considering that most of the mathematical literature on this subject might be too difficult for newcomers to the subject. The author motivates well the need for F-theory, being that of a theory with twelve-dimensional symmetry that is compactified on the torus. F-theories are thus a Type IIB theory with SL(2,Z) modular symmetry. Elliptic fibrations, of much recent interest in the mathematics community, are shown to originate in the (non-perturbative) compactification of a Type IIB theory on a manifold B, via F-theory compactified on an elliptic fibration of the manifold B.

Product Description
With an Introduction and Notes by Roger Clark, University of Kent at Canterbury One of the great Classics of Western Literature, Les Miserables is a magisterial work which is rich in both character portrayal and meticulous historical description. Characters such as the absurdly criminalised Valjean, the street urchin Gavroche, the rascal Thenardier, the implacable detective Javert, and the pitiful figure of the prostitute Fantine and her daughter Cosette, have entered the pantheon of literary dramatis personae.Download Description
Since geniuses, like demons, recognize the presence of a superior God by certain signs, Thenardier comprehended that he had to deal with a very strong person. It was like an intuition; he comprehended it with his clear and sagacious promptitude.Customer Reviews:

"Les Miserables" : Victor Hugo's grestest achievement.......2001-09-16
Such an important, profound and philosophical theme could only have been selected by a visionary such as Victor Hugo - whom I consider the greatest novelist of the 19th Century.
Other than Ayn Rand's "Atlas Shrugged" I do not know any single novel in world literature which seeks to present a unique philosophy to change the world and give a new direction to human existence.
According to me, the plot-theme is : "The step-by-step purification of a man's soul and his achievement of spiritual perfection."
Jean Valjean is the hero of the novel. The best years of his life have been wasted because of the iniquities and injustice of the prevailing social order. Emerging from prison after 19 years, his soul is immersed in anger, bitterness, hatred and a feeling of vengeance against society. How he acieves spiritual perfection, as viewed by Hugo, is what the story is all about.
However, this point has not been recognised by many. While most say that the theme is : "The injustice of society towards the lower classes", Hugo's intention was to dramatise "Man's struggle against the laws of society".
Keeping this in view, the accepted plot theme is (as best defined by Ayn Rand) : "The lifelong flight of an ex-convict from a ruthless representative of the law", this representative being Javert.
However, the struggle of Jean Valjean continues long after his conflict with Javert is resolved.
Victor Hugo is not just showing that Conscience is above Law, but this: what is the highest level of selflessness and self-sacrifice a man is capable of and what makes it possible.
As far as I can see, the accepted plot-theme has been identified the way it has been, because it defines a specific purpose(i.e., Javert's pursuit of Jean Valjean). Perhaps critcs would dismiss my point of view because neither is it Jean Valjean's explicit goal to become perfect nor does he set himself an objective which would symbolize his attainment of perfection.
But I look at the plot to have been construsted in a manner which inevitably leads Jean Valjean to perfection.
Bishop Myriel is the guiding image for Jean Valjean:his role represents how love and compassion can resurrect a man's conscience.
Fantine is the symbol of the woman and Cossette is the symbol of the child who are the victims of social evils.
Javert-the implaccable, ruthless and awe-inspiring policeman who shall never compromise on his values - is the symbol of blind conformity to the existing legal and social order.
One of the greatest achievements of "Les Miserables" is its sweeping sense of drama. What I love most about Hugo is the superb dramatic situations - suspenseful, thrilling, emotionally intense - he creates.
The scenes are so breathtakingly grandiose and mind-blowing that one can only think : "How did he get such a brilliant idea??!!"
The best part of the novel is the fighting at the barricades during the July Revolution in Paris - led by, perhaps the most admirable hero in 19th Century Romantic fiction - Enjolras.
Enjolras - despite a minor role - made a greater impact on me than the two central characters - Jean Valjean and Marius. One also cannot forget the lovable, heroic, 12 year old Gavroche.
The greatest drawback of "Les Miserables" is the plethore of esssays on various social, historical, religious and other issues, which are exasperatingly long, which interrupt the plot, make the novel cumbersome and the reader impatient.
However, they give the reader a picture of the world which Hugo had in mind (and which he wanted to revolutionize-and how) while writing the book.
They may not be directly related to the plot, but are certainly related to the meaning of the novel.
Further, the plot tends to become loose at times. The coincidences are rather naive and force the reader to conclude that they are meant solely to bring coherence in the story or to present a particular aspect of Hugo's philosophy.
Some may find the descriptions unnecessarily meticulous, though in poetic terms they are stunningly beautiful.
However, all this seems irrelevant if we concentrate on the profound pschycological analysis of the value-conflicts of Jean Valjean (and Javert) rarely matched in world literature; the scope and intellectual value of the novel; its immense social and philosophical significance and its wonderful portrayal of man as a heroic being.
But above all is the unsurpassable dramatic treatment rendered by Hugo's genius : the sheer artistry, the incomparable ingenuity, the soulful emotional content, the startling originality and compelling suspense-there is NO OTHER SINGLE WRITER IN THE WORLD who has equalled Hugo in this aspect-make, in addition to its numerous merits, "Les Miserables" one of the greatest achievements of the human mind.

Eponine: Truly the most fascinating character of the novel!.......1998-01-05
Upon reading all of the other reviews, I was startled that nobody even mentioned the character of Eponine. She is the epitome of progress and definately the most intriguing, not to mention original, characters of the novel. She was brought up to lie and steal, but yet had room in her hardended heart to love Marius. At the beginning we see her as a bratty, jealous child and yet in the end she was a martyr. I feel Eponine made one of the most remarkable changes of attitude in the novel. Her progress is commendable. May we all have such great revelations.
Truly the most remarkable and moving book I've ever read. A must-read!
