Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The magnitude and rapidity of the changes in the concentrations of APPs, together with their short half-life, suggest an important role for these proteins in the establishment of host defense. APPs are regarded as having general functions in trapping of micro-organisms and their products, in activating complement, in binding cellular remnants like nuclear fractions, in neutralizing enzymes, scavenging free radicals, and in modulating the hosts immune response. Despite vast pro- and anti-inflammatory properties ascribed to individual APPs, their function during health and disease remains incompletely defined. 190 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Urinary tract infections (UTI) continue to be under the most common bacterial infections worldwide. Diagnostic and treatment have substantial financial burden on society. In the USA, UTIs are responsible for more than 7 million physician visits annually and about 15% of all community-prescribed antibiotics in the USA are dispensed for UTIs. About 50% of women will experience at least one UTI episode during lifetime, about 1 million emergency department visits due to UTI in the USA alone, resulting in more than 100 000 hospital admissions annually, most often for pyelonephritis. Moreover, UTIs are also the leading cause of hospital-acquired infections, accounting for approximately 40% of all such cases. The majority of these cases are catheter-associated. Therefore, nosocomial UTIs comprise perhaps the largest institutional reservoir for nosocomial antibiotic-resistant pathogens. Beside the economic impact, UTIs affect also significantly the quality of life of the affected population. The aim of this book is to highlight problematic aspects and recent advances in the field of UTIs. The book is divided in three parts. 186 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Arteriovenous fistulas are shunts between arteries and veins that can be found in many organs of the human body such as the brain, skin, eye and lung. These lesions can be symptomatic by causing ischemia, through the process of the steal phenomenon, or vascular congestion and subsequent hemorrhage, eg. intracerebral hemorrhage of a ruptured dural arteriovenous fistula. The etiology of these lesions is not fully understood, some are congenital and others are acquired. On the other hand, iatrogenic arteriovenous fistulas, such as in hemodialysis patients, can be a life-saving procedure. This book provides a clear and concise review of the diagnosis and management of arteriovenous fistulas throughout the human body. It could be a great resource to medical students, residents, fellows, professors and researchers in the field. 212 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Advanced lithography grows up to several fields such as nano-lithography, micro electro-mechanical system (MEMS) and nano-phonics, etc. Nano-lithography reaches to 20 nm size in advanced electron device. Consequently, we have to study and develop true single nanometer size lithography. One of the solutions is to study a fusion of top down and bottom up technologies such as EB drawing and self-assembly with block copolymer. In MEMS and nano-photonics, 3 dimensional structures are needed to achieve some functions in the devices for the applications. Their formation are done by several methods such as colloid lithography, stereo-lithography, dry etching, sputtering, deposition, etc. This book covers a wide area regarding nano-lithography, nano structure and 3-dimensional structure, and introduces readers to the methods, methodology and its applications. 262 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The mode of action by radiation is postulated to be the production of double strand breaks of DNA. The repair of double strand breaks occurs through non homologous end joining through acetylation of histone proteins by histone acetyltransferases (HATs). The fixation of double strand breaks through HAT inhibitors is a promising application for radiation sensitization in the clinic.P53 is a tumour suppressor gene and its mutation has been implicated in 60% of human cancers. As one of the pivotal anticancer genes, P53 controls the transcription and translation of a series of genes. The kinetics of DNA double strand break generation and their co relation to P53 status, ATM and ARF activation are computed and modelled for understanding the potential of such research. 228 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The idea of this book was born due to the rapid increase of the interest in excellence of agricultural production in the aspect of both ¿ the quality of raw material for food production as well as in the aspect of environment protection. Agrophysics is a field of science that focuses on the quality of agriculture as a whole i.e. the interaction between human and environment, especially the interaction between soil, plant, atmosphere and machine. Physics with its laws, principles and rules is a good tool for description of the interactions, as well as of the results of these interactions. Some aspects of chemistry, biology and other fields of science are also taken under consideration. This interdisciplinary approach can result in holistic description of processes which should lead to improvement of the efficiency of obtaining the raw materials to ensure a sufficient amount of food, safe for human health. This book could be regarded as the contribution to this description. The reader can find some basic as well, as more particular aspects of the contemporary agriculture, starting with the soil characteristics and treatment, plant growth and agricultural products¿ properties and processing. 410 pp. Englisch.
