Buch. Zustand: Neu. Neuware -Pleural diseases are usually accompanied by pulmonary or nonpulmonary (heart, kidney, thyroid, systemic) diseases. Rarely, pleural diseases are solitary lesions. Pleural effusions are frequent manifestations of pleural diseases. Their treatment depends on the cause of effusion. Tuberculous and nontuberculous inflammation of pleura cause effusion as well as benign and malignant tumors. Talc treatment is one of the modalities of therapy for pleural effusions. Asbestosis is still the leading cause of pleural tumors. A solitary fibrous tumor of pleura is a mesenchymal tumor with various morphological patterns but with a consistent immunophenotype. A high proliferative index requires frequent follow-up because of possibe relapse and mandatory oncological treatment. A pleural malignant mesothelioma is aggressive and is the most frequent tumor of mesothelial origin.

Buch. Zustand: Neu. Neuware -Staphylococcus spp. and Streptococcus spp. have not only got pathogenic isolates, but also non-pathogenic isolates. Staphylococcus spp. and Streptococcus spp. that are Gram positive cocci are the main pathogens in several infections. Virulence factors such as usual and unusual surface proteins encoded by resistance genes are the main causes of pathogenesis. Multidrug-resistant pathogens that are the main causes of morbidity and mortality worldwide have the ability to synthesize a number of destructive enzymes encoded by resistance genes such as -lactamases. Resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA), Streptococcus pneumoniae, Group A, and Group B Streptococcus have emerged throughout the world. To eliminate these resistant pathogens that cause untreatable, acute, and chronic infections, different new antimicrobials must be developed and used. The goal of this book is to provide the latest information about the above topics.Books on Demand GmbH, Überseering 33, 22297 Hamburg 120 pp. Englisch.

Buch. Zustand: Neu. Neuware -The mitochondrion is a unique and ubiquitous organelle that contains its own genome, encoding essential proteins that are major components of the respiratory chain and energy production system. Mitochondria play a dominant role in the life and function of eukaryotic cells including neurons and glia, as their survival and activity depend upon mitochondrial energy production and supply. Besides energy production, mitochondria also play a vital role in calcium homeostasis and may induce apoptosis by excitotoxicity. Mitochondrial dysfunction is related to common neurological diseases, such as Parkinson's disease, Alzheimer's disease, Friedreich's ataxia, Huntington's disease, and Multiple Sclerosis. An efficient treatment of mitochondrial dysfunction would open new horizons in the therapeutic perspectives of a substantial number of inflammatory and degenerative neurological disorders.Books on Demand GmbH, Überseering 33, 22297 Hamburg 124 pp. Englisch.

Buch. Zustand: Neu. Neuware -Recently, remarkable progress has been made in the area of preclinical xenotransplantation experiments. Surprisingly, a heterotopic heart from the gene-editing pig continued to beat for almost 2.5 years, when implanted in the monkey abdomen, and a pig life-supporting kidney could also function for over 1.3 years in monkeys. Concerning islets, islets from gene-editing pigs could work for more than one year in monkeys. It is noteworthy that one group reported a survival of adult wild-type pig islets of over 600 days. On the other hand, the progress in these preclinical trials strongly affected not only the xenotransplantation study itself but regeneration studies to use pigs as a scaffold to foster human induced pluripotent stem cells.Books on Demand GmbH, Überseering 33, 22297 Hamburg 156 pp. Englisch.

Buch. Zustand: Neu. Neuware -Probiotic bacteria are found in the intestinal microbiota of the host and favor multiple metabolic reactions.

Buch. Zustand: Neu. Neuware -The two fields of knowledge ¿geology¿ and ¿hydrology¿ always go hand in hand, often giving rise to the terms ¿geohydrology¿ and ¿hydrogeology.¿ The importance of the science of water, commonly called ¿hydrologic science,¿ is always complemented by the ¿science of the interior of the earth.¿ Whereas hydrology is concerned with the quality and quantity of underground water, its movement, extraction, and recharge, geology talks of the rock matrix and the structure in which this water is contained, stored, and moved around.In recent times, the knowledge of geohydrology or the hydrology of groundwater has gained an impetus many times its original scale; and with that, acquisition, expansion, research, advancement, and dissemination of this knowledge have become more significant. With so many dimensions of geohydrology available for exploration, research, and technological advancement, any work contributing to any dimension of geohydrology and groundwater will find its right place. This compilation of chapters is going to play a very important part in furthering the knowledge of geohydrology and may prove an interesting and useful read for various cross-sections of academia, researchers, engineers, hydrologists, and all categories of water consumers.Books on Demand GmbH, Überseering 33, 22297 Hamburg 120 pp. Englisch.

Buch. Zustand: Neu. Neuware -Elastography, the science of creating noninvasive images of mechanical characteristics of tissues, has been rapidly evolving in recent years. The advantage of this technique resides in the ability to rapidly detect and quantify the changes in the stiffness of soft tissues resulting from specific pathological or physiological processes. Ultrasound elastography is nowadays applied especially on the liver and breast, but the technique has been increasingly used for other tissues including the thyroid, lymph nodes, spleen, pancreas, gastrointestinal tract, kidney, prostate, and the musculoskeletal and vascular systems. This book presents some of the applications of strain and shear-wave ultrasound elastography in hepatic, pancreatic, breast, and musculoskeletal conditions.Books on Demand GmbH, Überseering 33, 22297 Hamburg 146 pp. Englisch.

Buch. Zustand: Neu. Neuware -Lagoon Environments Around the World - A Scientific Perspective covers a wide range of topics. Typically bordering between land and sea, lagoons are among the most diversely utilized waterways on the planet. Lagoons are extremely important environments socio-economically, and their usage places ever increasing stress on these very sensitive aquatic regions. The effective management of shallow aquatic environments requires a detailed scientific understanding of the various contributary natural processes. This has both environmental and economic implications, especially where there is any anthropogenic involvement. This book draws on international scientific research to examine the following lagoon related issues: classification, circulation hydrodynamics, ecosystems, sedimentation, anthropogenic stresses, and response to extreme events. The research was carried out by researchers who specialize in shallow water processes and related issues.Books on Demand GmbH, Überseering 33, 22297 Hamburg 246 pp. Englisch.
