The COVID-19 pandemic caused by the SARS-CoV-2 virus has affected nearly every country and territory in the world. Although worldwide vaccination efforts have reduced the risk of serious disease outcomes, disparities in distribution have led to multiple waves of SARS-CoV-2 outbreaks and the emergence of variants of concern, some of which have enhanced infectivity and ability to evade existing vaccines. Hence there is an increasing interest in understanding the evolution of viruses like SARS-CoV-2, as well as improving our capacity to effectively current and manage future pandemics.This new volume reviews the most effective omic techniques for increasing our understanding of COVID-19, to improve diagnostics, prognostics, and genomic surveillance, and to facilitate development of effective treatments and vaccines. Chapters are written by an international team of experts and explore methods in the areas of genomics, transcriptomics, proteomics, and metabolomics. Techniques used toassess physiological function at the molecular level and artificial intelligence approaches used for more effective validation and translation of biomarker candidates into clinical use are also discussed. This book is an excellent resource for researchers studying biomarkers, virology, metabolic diseases, and infectious diseases, as well as clinical scientists, physicians, drug company scientists, and healthcare workers.

This book brings together the latest information on almond genomics and transcriptomics, with a particular focus on cutting-edge findings, tools, and strategies employed in genome sequencing and analysis with regard to the most important agronomic traits. Cultivated almond [(Prunus dulcis (Miller) D. A. Webb, syn. Prunus amygdalus Batsch., Amygdalus communis L., Amygdalus dulcis Mill.)] is a tree crop producing seeds of great economic interest, and adapted to hot and dry climates. Domesticated in Southeast Asia, its small diploid genome and phenotypic diversity make it an ideal model to complement genomics studies on peach, generally considered to be the reference Prunus species. Both represent consanguineous species that evolved in two distinct environments: warmer and more humid in the case of peach, and colder and xerophytic for almond. The advent of affordable whole-genome sequencing, in combination with existing Prunus functional genomics data, has now made it possible to leverage the novel diversity found in almond, providing an unmatched resource for the genetic improvement of this species.

Advances in cancer genomics are transforming our understanding of cancer, and have profound implications for its prevention, diagnosis, and treatment. Evolutionary dynamics suggests that as few as two mutations can cause transformation of normal cells into cancer stem cells. A process of Darwinian selection, involving a further three or more mutations, taking place over a period of years, can then result in progression to a life-threatening tumour. In many cases the immune response can recognise and eliminate the mutant cells, but most advanced tumours have mutations that activate immune checkpoints and enable the tumour to hide from the immune system. For the most hard-to-treat tumours, future progress will require molecular diagnostics to detect cancer-causing mutations in healthy subjects, and new drugs or vaccines that prevent the progression process.Chapters of this book deal with the signalling pathways that control cell division, and changes in these pathways in cancer cells. Three cell cycle checkpoints that are often mutated in cancer are analysed in detail. A discussion of chronic myeloid leukaemia illustrates the role of reactive oxygen species in driving progression from a chronic to an acute condition. A single drug that suppresses reactive oxygen can prevent disease progression and turn an otherwise deadly disease into a condition that can be managed to enable many years of normal life. Another chapter discusses chronic myelomonocytic leukaemia, a disease that involves both genetic and epigenetic change. Tumour progression is discussed as a multi-stage process in which cancer stem cells evolve into genetically unstable, invasive, metastatic, drug-resistant growths. Each of these stages can act as targets for drugs or immunomodulators, but the future of cancer treatment lies in understanding tumour dynamics, and arresting malignancy at the earliest possible stage.Evolutionary dynamics is a primarily mathematical technique, but the target readership will be tumour biologists, clinicians, and drug developers. Computational detail is provided in an online supplement, but the main text emphasises the implications of the dynamics for an understanding of tumour biology and does not require mathematical expertise.

This edited book is a compilation of tangible research findings and actual experiences on various salt tolerant rice breeding programmes, that have been successfully practiced and continuing to do so by research centres in South East Asia, with major emphasis in India, Bangladesh and Philippines. Rice being one of the most important staple crops of the world, its production and productivity have to be kept on increasing so as to feed the burgeoning population. This is a very challenging task in the midst of shrinking resource base and arable lands in the face of climate change. Salt stress is the second major abiotic stress, next only to drought, which greatly affects rice production. To overcome this problem, development of improved salt tolerant rice cultivars coupled with appropriate package of practices, an ecologically sound and socially acceptable strategy should be developed which is well within the reach of marginal farmers. With rapid advances in molecular biology, mechanisms underlying the complexity of the trait are better understood now than before. Selection of appropriate parents, desired mapping populations, precise phenotyping are the key components to underpin the mapping and utilization of reliable QTLs. Understanding genetics of salt tolerance, identifying the robust molecular markers and targeted utilization of available molecular markers form the sound basis to develop the commercial products with more precision and speed. This book covers entire range of topics: starting from biophysical characterization of salt stressed areas in different rice ecologies, conventional and molecular breeding approaches for mapping salt tolerance and subsequent development of improved rice varieties for commercial cultivation and their societal impacts. This book is of interest to scientists, faculty, policy makers and administrators. It also serves as a resource guide to graduate students of agriculture particularly plant breeding, plant physiology, molecularbiology and soil science.

Today, human generations have been divided into different groups, and in each generation, some issues are seen more and more, because one generation has grown up with the same facilities, familiarity with the norms, beliefs, characteristics, moral and behavioral traits of different generations. It helps to know better about ourselves and how to interact with others. The theory of generations was first proposed in 1923 by Karl Mannheim, a Hungarian philosopher and sociologist, and was later studied and developed by Graeme Codrington. The classification of generations that we will discuss in this article is based on the political, social and economic conditions of people born in different time periods in Europe and America, and the mentioned historical periods do not necessarily correspond to the culture of our own country; But in many ways, people born in the same generations all over the world have the same characteristics (Simonetti and Feereira 2019). The present research was conducted in order to compare personality traits and psychological well-being in generations z, y, x in Iranian society.
