SARS-CoV-2 Spike Protein Convergent Evolution: Impact of Virus Variants on Efficacy of COVID-19 Therapeutics and Vaccines (SpringerBriefs in Microbiology)

by Daniele Focosi

This book reviews the current knowledge of the globally circulating SARS-CoV-2 variants, highlights their distinct genetic characteristics and associated conformational changes in the viral spike protein, and profoundly discusses the mechanisms of convergent evolution that led to the rise of these mutated strains at different geographic regions during the Covid-19 pandemic. Furthermore, the book explores how these variants do and may impact the efficacy of established neutralizing antibody-based (nAb) vaccines and therapeutics by analysing latest in vivo and in vitro clinical data. Finally, the author discusses ways on how nAb Covid-19 treatment derived immune escape of SARS-CoV-2 could be minimized in the future.

SARS-CoV2 (COVID-19) Pandemic Control and Prevention: An Epidemiological Perspective

by Laurens Holmes, Jr.

This is the first comprehensive text to provide not only a detailed explanation of how the SARS-CoV2 (COVID-19) virus is spread within human populations, but also an epidemiological analysis and interpretation of viral pandemics to enable better measures for prevention and control. Providing an introduction to the physiology of both the human immune system and the SARS-CoV2 virus, specifically the virus’s replicative potential and our own vulnerability, the book offers an in-depth understanding of how the pandemic evolved. It also highlights the aberrant epigenomic mechanistic process in pathogenic microbe’s replication and survival, implying gene and environment interaction that affected different populations. Citing a range of environmental conditions, from structural and systemic racism to malnutrition and low-socioeconomic status, the book examines how these factors exacerbated existing health disparities, resulting in a disproportionate burden of morbidity and mortality on certain social groups. Also providing invaluable guidance on how future iterations of this pandemic may be better prevented and controlled, this will be a defining book for students, researchers and professionals within Public Health and Clinical Medicine to better understand the SARS-CoV2 (COVID-19) virus, and how to protect the most vulnerable social groups.

SAS for Epidemiologists

by Charles Dimaggio

This comprehensive text covers the use of SAS for epidemiology and public health research. Developed with students in mind and from their feedback, the text addresses this material in a straightforward manner with a multitude of examples. It is directly applicable to students and researchers in the fields of public health, biostatistics and epidemiology. Through a "hands on" approach to the use of SAS for a broad number of epidemiologic analyses, readers learn techniques for data entry and cleaning, categorical analysis, ANOVA, and linear regression and much more. Exercises utilizing real-world data sets are featured throughout the book. SAS screen shots demonstrate the steps for successful programming. SAS (Statistical Analysis System) is an integrated system of software products provided by the SAS institute, which is headquartered in California. It provides programmers and statisticians the ability to engage in many sophisticated statistical analyses and data retrieval and mining exercises. SAS is widely used in the fields of epidemiology and public health research, predominately due to its ability to reliably analyze very large administrative data sets, as well as more commonly encountered clinical trial and observational research data.

SCF and APC E3 Ubiquitin Ligases in Tumorigenesis

by Hiroyuki Inuzuka Wenyi Wei

This SpringerBrief explores the physiological roles of Skp1-Cullin1-F-box Complex (SCF) and Anaphase Promoting Complex (APC) in normal cells and in tumor formation. These two related, multi-subunit E3 ubiquitin ligase enzymes, APC and SCF are thought to be the major driving forces governing proper cell cycle progression Defective cell cycle regulation leads to genomic instability and ultimately, cancer development. Selective degradation of key cell cycle regulators by the ubiquitin-proteasome system has been proven to be a major regulatory mechanism for ensuring ordered and coordinated cell cycle progression. The SCF and APC E3 ligases have been characterized to play pivotal roles in regulating the cell cycle progression by timely degrading various critical cell cycle regulators. This Brief reviews recent studies that have shown that deregulation of signaling pathways in which the two ubiquitin ligases are involved causes aberrant cell cycle regulation, in turn leading to tumorigenesis The text also discusses how SCF and APC may present promising therapeutic targets to treat various cancers.

SCN2A-Related Disorders (Elements in Genetics in Epilepsy)

by Megan Abbott Kevin J. Bender Andreas Brunklaus Scott Demarest Shawn Egan Isabel Haviland Jennifer A. Kearney Leah Schust Myers Heather E. Olson Stephan J. Sanders Christina SanInocencio Joseph Symonds Christopher H. Thompson

SCN2A encodes a voltage-gated sodium channel (designated NaV1.2) vital for generating neuronal action potentials. Pathogenic SCN2A variants are associated with a diverse array of neurodevelopmental disorders featuring neonatal or infantile onset epilepsy, developmental delay, autism, intellectual disability and movement disorders. SCN2A is a high confidence risk gene for autism spectrum disorder and a commonly discovered cause of neonatal onset epilepsy. This remarkable clinical heterogeneity is mirrored by extensive allelic heterogeneity and complex genotype-phenotype relationships partially explained by divergent functional consequences of pathogenic variants. Emerging therapeutic strategies targeted to specific patterns of NaV1.2 dysfunction offer hope to improving the lives of individuals affected by SCN2A-related disorders. This Element provides a review of the clinical features, genetic basis, pathophysiology, pharmacology and treatment of these genetic conditions authored by leading experts in the field and accompanied by perspectives shared by affected families. This title is also available as Open Access on Cambridge Core.

SDG 14: A Machine-Generated Overview of Recent Literature

by Sergio Rossi

This book focuses, in seven chapters, on the perspectives and solutions that different research groups offer to try to address problems related to SDG 14: Life Below Water. The different objectives developed in SDG 14 are treated independently, with an attempt to give a global vision of the issues. The mechanism used to select the book's content was through an Artificial Intelligence program, choosing articles related to the topics by means of keywords. The program selected those articles, and those that were not related to the topic or did not focus on SDG 14 were discarded by a subject matter expert. Obviously, the selection was partial and the entire subject is not covered, but the final product gives a very solid idea of ​​how to orient ourselves to delve deeper into the topic of SDG 14 using published chapters and articles. The AI program itself selected the text of these contributions to show the progress in different topics related to SDG 14. This mode of operation will allow specialists (and non-specialists) to collect useful information for their specific research purposes in a short period of time. At a time when information is essential in order to move quickly by providing concrete answers to complex problems, this type of approach will become essential for researchers, especially for a subject as vast as SDG 14.

SH Domains

by Natalya Kurochkina

This book covers structure, function, and important roles of the SH domains, structure-function relationships, the versatile nature of their action, mechanisms of aggregation, specificity of interactions, impact of mutations on protein functional dysregulation, and cell signaling. Their involvement in various cellular processes such as migration, invasiveness, actin reorganization, shaping spines, determination of the morphology assembly of fibrils, and mechanotransduction makes these molecules attractive drug targets. Substrates, inhibitors and activators of PTKs present a wide variety of therapeutic agents in the context of delivering treatments for numerous pathologies. The new emerging field of stem cell therapies and design of biomaterials for treatments relies on the directed regulation of stem cell growth, differentiation and morphology, as well as the production of biomimetic scaffolds that respond to programmed signals. Advances in deciphering the mechanisms of action of these important molecules will lead to the implementation and success of their vital applications.
