Detection of pathogenic infections in neurological disorders through recycling of gene expression data


Book Description

For increasing the knowledge about small RNA an online platform was built in this thesis, homogenizing the analysis of sequencing data from over 4,000 samples collected in different laboratories worldwide from various organisms. Consequentially, tissue and disease specific biomarkers were detected and evidence was found for bacterial and viral infections of the sequenced tissues. This motivated the development of an algorithm for analyzing non-host RNA sequencing reads for detecting pathogenic abundance in the host. Focusing on neurological diseases, bacterial presence is suggested in brains of dementia patients. The platform and the algorithm can help scientists to add important leads to their own studies. In dieser Arbeit wurde eine Online-Plattform für small RNA entwickelt, die die Analyse der Sequenzierungsdaten von über 4.000 weltweit gewonnenen Proben verschiedener Organismen homogenisiert. Mit ihr wurden gewebe- und krankheitsspezifische Biomarker gefunden, sowie Hinweise auf bakterielle und virale Infektionen der sequenzierten Gewebe. Dies motivierte die Entwicklung eines Algorithmus für die Analyse von Nicht-Wirts-RNA-Sequenzierungsdaten zum Detektieren von Pathogenen. Bei einer Fokussierung auf neurologische Erkrankungen wurde bakterielle Präsenz im Gehirn von Demenzpatienten detektiert. Die Plattform und der Algorithmus können der Wissenschaft behilflich sein, neue Studien mit wichtigen Informationen zu verbessern.




The Blood-Cerebrospinal Fluid Barrier


Book Description

Despite the existence of two barrier systems in the brain, research over the last century has mostly focused on the blood-brain barrier rather than on the blood-CSF barrier. Today, there is a greater understanding of the function of the blood-CSF barrier and of the choroid plexus, a tissue that is the primary site of this barrier. With the growing number of studies that focus on the role of the blood-CSF barrier in CNS homeostasis and neurological disorders, a modern overview of the blood-CSF barrier is long overdue. The Blood-Cerebrospinal Fluid Barrier is exclusively devoted to the blood-CSF barrier. Internationally renowned experts discuss the most recent progress in the field of choroid plexus physiology and update our knowledge of the function of the blood-CSF barrier. The book begins with an overview of the development and morphology of the choroid plexus, and then covers various aspects of its function, such as the regulation of choroidal blood flow, ion transport, and the production and transport of polypeptides. Following an extensive section on the role of the choroid plexus in CNS disorders, the final section discusses in vitro, in vivo, and in situ models of the blood-CSF barrier. This unique book analyzes a wealth of new research on the proven and potential roles of the choroid plexus/blood-CSF barrier in the brain. It is a valuable resource that will foster future studies in neuroscience, pharmacology, and toxicology.







Non-coding RNAs in Cardiovascular Diseases


Book Description

This book presents the latest research on non-coding RNAs in cardiovascular disease, a major cause of death worldwide. Non-coding RNAs play a significant role in development, proliferation, differentiation and apoptosis. Since altered non-coding RNA expression is often associated with various diseases, their potential use in diagnostics, prognostics and therapeutics is an important current area of study. The book consists of six parts: 1) An overview of non-coding RNAs and cardiovascular system, 2) Bioinformatics and interactions, 3) Non-coding RNA regulation in cardiovascular system, 4) Non-coding RNAs and cardiovascular diseases, 5) Potential biomarkers and therapeutic implications, 6) Future prospects. It is particularly useful for researchers and students in the field of non-coding RNA and cardiovascular biology, as well as for cardiologists, pharmacologists and physiologists.







Human Herpesviruses


Book Description

This comprehensive account of the human herpesviruses provides an encyclopedic overview of their basic virology and clinical manifestations. This group of viruses includes human simplex type 1 and 2, Epstein–Barr virus, Kaposi's Sarcoma-associated herpesvirus, cytomegalovirus, HHV6A, 6B and 7, and varicella-zoster virus. The viral diseases and cancers they cause are significant and often recurrent. Their prevalence in the developed world accounts for a major burden of disease, and as a result there is a great deal of research into the pathophysiology of infection and immunobiology. Another important area covered within this volume concerns antiviral therapy and the development of vaccines. All these aspects are covered in depth, both scientifically and in terms of clinical guidelines for patient care. The text is illustrated generously throughout and is fully referenced to the latest research and developments.

Polyomaviruses and Human Diseases


Book Description

Science never solves apr oblem without creating ten more Geor ge Bernard Shaw How prophetic the above words prove to be when applied to the advances of 20th century medicine. Prior to Banting and Best, chnicians were unaware of the ravages of diabetes, patients simply wasted away and died. Following the purifica tion of insulin, clinicians now had to deal with diabetic retinopathy, diabetic neph ropathy and all the other complications of long-term diabetes. A little over 50 years ago, the first successful human kidney transplant was performed in Boston. The first 30 years of the experience had successes when compared to the alternative but were a constant struggle to get even 50% of the grafts from deceased donors to survive more than a year. However, the science continued to advance knowledge of the immune response. With this came more and increasingly powerful tools for the clinician. Suddenly, success rates of 80-90% at one year were attainable. With this success came new problems, new complications and clinicians now had to worry about the long-term consequences of their therapy as patients were surviving with functional grafts for extended periods. A particular infectious complication evolved with the application of ever more powerful immunosuppressant drugs. Astute clinicians noted that occasionally cellular rejections seemed to get worse with steroids. Despite their best efforts and the use of powerful drugs, patients lost their grafts to overwhelming interstitial infiltrates not seen before.




Microbial Threats to Health


Book Description

Infectious diseases are a global hazard that puts every nation and every person at risk. The recent SARS outbreak is a prime example. Knowing neither geographic nor political borders, often arriving silently and lethally, microbial pathogens constitute a grave threat to the health of humans. Indeed, a majority of countries recently identified the spread of infectious disease as the greatest global problem they confront. Throughout history, humans have struggled to control both the causes and consequences of infectious diseases and we will continue to do so into the foreseeable future. Following up on a high-profile 1992 report from the Institute of Medicine, Microbial Threats to Health examines the current state of knowledge and policy pertaining to emerging and re-emerging infectious diseases from around the globe. It examines the spectrum of microbial threats, factors in disease emergence, and the ultimate capacity of the United States to meet the challenges posed by microbial threats to human health. From the impact of war or technology on disease emergence to the development of enhanced disease surveillance and vaccine strategies, Microbial Threats to Health contains valuable information for researchers, students, health care providers, policymakers, public health officials. and the interested public.
