Available in PDF, EPUB and Kindle. Book excerpt: De tout temps, l'homme a eu conscience de l'intérêt thérapeutique des toxines. Certaines toxines végétales depuis longtemps utilisées figurent encore dans la pharmacopée actuelle. Viennent s'y ajouter depuis peu des toxines microbiennes. Cependant le maniement des toxines natives ou à peine modifiées reste délicat tant est faible la marge entre les effets toxiques et l'efficacité thérapeutique. Comment, dans une perspective médicale, canaliser la puissance d'action et l'efficacité d'une toxine ? Connaître sa structure, comprendre son mécanisme d'action n'est pas suffisant : il faut aussi identifier sa cible privilégiée, autrement dit un récepteur cellulaire, faute de quoi l'entreprise apparemment chimérique d'un détournement de sa puissance et de sa spécificité reste aveugle. Ce cap est franchi, depuis un certain nombre d'années, et le développement des recherches sur les toxines axées sur la thérapeutique est devenu foisonnant. Voyez telle ou telle toxine protéique ternaire, avec ses trois domaines, de fixation sur un récepteur membranaire, de translocation qui lui permet de franchir la membrane cellulaire, et d'activité enzymatique qui va alors pouvoir s'exercer dans la cellule. Qu'on parvienne à dissocier chacun de ces trois domaines en leur conservant leurs propriétés, et des possibilités nouvelles d'utilisation thérapeutique vont s'ouvrir, presque à l'infini semble-t-il. Car chacun d'entre eux pourra être couplé à une molécule active bien ciblée, et leur efficacité sera même améliorée pour peu qu'on parvienne à conjuguer leur action. Qu'un récepteur, qu'une molécule, propres au métabolisme ou à la physiologie d'une cellule cancéreuse soient identifiés, et des toxines conjuguées à un ligand de ce récepteur, de cette molécule (ce peut être un anticorps) bloqueront les canaux ioniques ou exerceront leur effet cytolytique sur cette seule cellule, sans nuire aux cellules saines. Nous voilà dégagés de l'utopie, le contenu de cet ouvrage le prouve abondamment. Et même si la concrétisation des promesses reste délicate, le champ d'action est si vaste initialement qu'il ne saurait rester improductif : il ne l'est d'ailleurs déjà plus.

Download or read book Treatment of Ovarian Cancer written by A. P. Bardos and published by Nova Publishers. This book was released on 2005 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new volume presents the latest research on therapies for ovarian cancer. Ovarian cancer is cancer that begins in the cells that constitute the ovaries, including surface epithelial cells, germ cells, and the sex cord-stromal cells. Cancer cells that metastasize from other organ sites to the ovary (most commonly breast or colon cancers) are not then considered ovarian cancer. According to the American Cancer Society, ovarian cancer accounts for 4 percent of all cancers among women and ranks fifth as a cause of their deaths from cancer. The American Cancer Society statistics for ovarian cancer estimate that there will be 25,400 new cases and 14,300 deaths in 2003. The death rate for this disease has not changed much in the last 50 years. Unfortunately, almost 70 percent of women with the common epithelial ovarian cancer are not diagnosed until the disease is advanced in stage -- i.e., has spread to the upper abdomen (stage III) or beyond (stage IV). The 5-year survival rate for these women is only 15 to 20 percent, whereas the 5-year survival rate for stage I disease patients approaches 90 percent and for stage II disease patients approaches 70 percent. Ovarian tumors are named according to the type of cells the tumor started from and whether the tumor is benign or cancerous. The three main types of ovarian tumors are: Epithelial Tumors, Germ Cell Tumors and Stromal Tumors.

Download or read book Molecular Basis of Human Blood Group Antigens written by Jean-Pierre Cartron and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of blood groups was born at the beginning of this century, when the field of immunology married that of genetics. Most of the subsequent progress in immunogenetics was achieved by British investigators. The six consecutive editions of the unequaled Blood Groups in Man have long been considered as the bible of blood groupers. It is quite unfortunate that this book has not been revisited since 1975. Although one cannot do without immunogenetics, which remains useful for the identification of new blood groups and genetic studies, the focus of interest has moved somewhat today. After several decades, the molecular basis of blood groups can be investigated by biochemists. From 1950 to 1980, the ABO, Hh, and Lewis blood groups served as models and their chemical basis came to be established. The red cell membrane glycophorins carrying the MN and Ss antigens and the glycolipids with P blood group specificities were also identified and characterized. The chemical basis of the other groups, however, remained largely unknown.

This book was released on 2010-08-28 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein hydrolysates, otherwise commonly known as peptones or peptides, are used in a wide variety of products in fermentation and biotechnology industries. The term “peptone” was first introduced in 1880 by Nagelli for growing bacterial cultures. However, later it was discovered that peptones derived from the partial digestion of proteins would furnish organic nitrogen in readily available form. Ever since, p- tones, which are commonly known as protein hydrolysates, have been used not only for growth of microbial cultures, but also as nitrogen source in commercial fermen- tions using animal cells and recombinant microorganisms for the production of value added products such as therapeutic proteins, hormones, vaccines, etc. Today, the characterization, screening and manufacturing of protein hyd- lysates has become more sophisticated, with the introduction of reliable analytical instrumentation, high throughput screening techniques coupled with statistical design approaches, novel enzymes and efficient downstream processing equipment. This has enabled the introduction of custom-built products for specialized appli- tions in diverse fields of fermentation and biotechnology, such as the following. 1. Protein hydrolysates are used as much more than a simple nitrogen source. For example, the productivities of several therapeutic drugs made by animal cells and recombinant microorganisms have been markedly increased by use of p- tein hydrolysates. This is extremely important when capacities are limited. 2. Protein hydrolysates are employed in the manufacturing of vaccines by ferm- tation processes and also used as vaccine stabilizers.
