Beyond the DNA code itself lies a hidden layer of control - the 3' untranslated region (3'UTR) of messenger RNA (mRNA). This tail-like region, though not translated into protein, plays a surprising role in shaping a cell's destiny. Multiple cleavage sites in the 3'UTR allow cells to choose which portion gets added, resulting in diverse mRNA forms. This diversity impacts how efficiently the mRNA is translated into protein. Researchers are finding connections between 3'UTR variations and cell functions like proliferation and differentiation. Even diseases like cancer may be linked to abnormal 3'UTR processing. Understanding how cells make these choices could unlock new avenues for treating diseases and deciphering the complexities of development.

Tras los éxitos de El emperador de todos los males y El gen, Siddhartha Mukherjee se adentra en la increíble y apasionante historia de la célula. 'En un relato a la vez lírico y amplio, Mukherjee nos lleva a través de una historia de la comprensión humana: desde el descubrimiento en el siglo XVII de que estamos formados por células hasta la actual tecnología de vanguardia para manipular y desplegar células con fines terapéuticos'.Th e New Yorker Bienvenidos a la apasionante historia de la célula. En este nuevo libro, el oncólogo y divulgador Siddhartha Mukherjee nos acompaña en un viaje fascinante a partir de uno de los mayores descubrimientos científicos de la historia: el hecho de que todos los organismos vivos complejos estén constituidos por unidades diminutas, autónomas y autorreguladas, esas que en el siglo XVII Robert Hooke vio a través de su microscopio y bautizó con el nombre que hoy conocemos. Aquel hallazgo, seguido de una cada vez mejor comprensión de la fisiología celular, cambió para siempre (y aún determina) la manera en que abordamos la medicina, la ciencia, la biología, las estructuras sociales y hasta la cultura. Una fractura de cadera, una parada cardiaca, el Alzheimer, el sida, un cáncer de pulmón... todo, absolutamente todo, puede explicarse como el resultado del funcionamiento anómalo de las células o de los ecosistemas que estas forman. Y también todo debería poder tratarse mediante su manipulación terapéutica. Esta revolución en el campo de la biología celular ya ha demostrado resultados transformadores y hoy se plantea como uno de los avances científicos que más vidas pueden salvar.Críticas:'Maravillosamente ambiciosa. La biología de la célula es compleja y colosal como la vida misma. No creo que ningún escritor pudiera tratar este asunto mejor'.The Times 'En parte misterio, en parte historia de aventuras, La armonía de la célula es una irresistible incursión en los confines de la ciencia médica y un recordatorio del poder del ingeniohumano que probablemente dejará a los lectores asombrados y esperanzados'.Jennifer Egar, autora ganadora del Pulitzer 'La escritura de La armonía de la célula es tan agradable que te dejas llevar por su música'.The New York Times 'Con una investigación profunda, La armonía de la célula es un extraordinario viaje a través de la historia de los descubrimientos hasta llegar a la medicina celular más innovadora que se practica en la actualidad y a la promesa de lo que está por venir'.Paul Nurse, Premio Nobel de Fisiología y Medicina en 2001 'Un narrador extraordinariamente dotado. Las ideas del autor sobre el futuro próximo de la medicina son tan convincentes como inspiradoras. Otro éxito de Mukherjee'.Publishers Weekly'Una exploración fiable, oportuna y, lo que es más importante, biológicamente precisa de lo que significa ser humano'.The Guardian

This richly illustrated book, replete with several QR codes for short, original films, focuses on being compassionate to creatures less than ourselves.From the Introduction: We go through our lives consuming the flesh of other living animals despite our capacity to refrain from doing so. It has been estimated that we kill 55 billion animals each year for food (Hussain). We are willingly neglecting the welfare of 55 billion lives every year when we have other food options for our survival. In the 21st century, we have a moral duty and responsibility not to continue the horrendous suffering endured by animals simply for profit and appetite. Ending the unimaginable suffering of animals for which we bear a responsibility will increase our own eudaimonia since being compassionate to others also benefits us. As we expand our moral circle of compassion and consideration, the individual self can gain a greater sense of well-being.

The erosion of biodiversity is currently highly publicized. Militant movements accuse humans of destroying nature and being responsible for a sixth mass extinction. However, this anxiety-provoking message is sometimes based on misconceptions, false or partisan ideas, and media relays that favor and amplify alarmist information. If the situation of certain populations is worrying, it is not a general phenomenon because others are expanding. Rather than holding a globalizing discourse, it is necessary to recontextualize and relativize the debate to better define the necessary actions. Biodiversity Erosion analyzes numerous scientific publications, as well as alarming discussions, emphasizing the multiple biases present in the way information is presented. This book questions the relevance of the notion of species and the desire to compile an inventory of all living things. It argues for a less Manichean approach to our relationship with nature.

This book comprehensively covers the topic of COVID-19 and other pandemics and epidemics data analytics using computational modelling. Biomedical and Health Informatics is an emerging field of research at the intersection of information science, computer science, and health care. The new era of pandemics and epidemics bring tremendous opportunities and challenges due to the plentiful and easily available medical data allowing for further analysis. The aim of pandemics and epidemics research is to ensure high-quality, efficient healthcare, better treatment and quality of life by efficiently analyzing the abundant medical, and healthcare data including patient's data, electronic health records (EHRs) and lifestyle. In the past, it was a common requirement to have domain experts for developing models for biomedical or healthcare. However, recent advances in representation learning algorithms allow us to automatically learn the pattern and representation of the given data for the development of such models. Medical Image Mining, a novel research area (due to its large amount of medical images) are increasingly generated and stored digitally. These images are mainly in the form of: computed tomography (CT), X-ray, nuclear medicine imaging (PET, SPECT), magnetic resonance imaging (MRI) and ultrasound. Patients' biomedical images can be digitized using data mining techniques and may help in answering several important and critical questions related to health care. Image mining in medicine can help to uncover new relationships between data and reveal new and useful information that can be helpful for scientists and biomedical practitioners. Assessing COVID-19 and Other Pandemics and Epidemics using Computational Modelling and Data Analysis will play a vital role in improving human life in response to pandemics and epidemics. The state-of-the-art approaches for data mining-based medical and health related applications will be of great value to researchers and practitioners working in biomedical, health informatics, and artificial intelligence..

What is sex? Has it always existed? What purpose does it serve? Why are there penises and vaginas? These questions are at the very core of Dirty Biology, an erudite (and hilarious) graphic novel that aims to teach you everything you wanted to know about sex--and then some."Sex" can mean a number of things. It can refer to sex organs, to sex types, to the act of copulation, or to the simple exchange of genetic material. This book explains what we actually mean when we talk about sex and reveals a wealth of astonishing scientific details along the way. For example, did you know that some species can have sex without genitals? And when it comes to genitals, did you know that there's an amazing diversity of these across species? From the evolution of penises and vaginas to far-fetched mating rituals and the shocking consequences of the sex act, Dirty Biology exposes sex for what it is: a lot more interesting and more complicated than the simplistic image we often have of it.

For author Don C Reed, father of a paralyzed son, the California Institute for Regenerative Medicine (CIRM) is the greatest medical advance since penicillin.REVOLUTIONARY THERAPIES is Reed's third book about the $3 billion stem cell program.Voted into law in November 2004, CIRM is now running out of money.Should its funding be renewed? Thereby hangs a tale, or rather several dozen of them, for each of the book's 71 short chapters is framed by a yarn or vignette.The factual background is accurate, vetted by the scientists, but Reed's goal is clearly both entertainment and education.A favorite example is a little girl named Evie, imprisoned in a plastic bubble: her body's immune system did not work, and she would die outside. She joined a CIRM clinical trial ... Imagine how Evie's parents felt - when she got well.Some stories are comical, like ""How Stem Cell Research Saved My Car""; others surprising, like the comparison between politics and the giant crocodile Gustave; others are tragic or inspiring: but all point to this:More than 100 million Americans suffer chronic disease, causing mountains of medical debt - and the only way to reduce that expense ($3 trillion last year) - is cure.

This book provides an insightful sociological study of the declining Japanese population, using statistical analysis to establish the significance of municipal power using demographic data on national, regional, prefectural and municipal levels. Penned by one of Japan's eminent sociologists, it provides a quantitative characterization of population decline in Japan with a focus on regional variation, and identifies the principal explanatory factors through GPI statistical software tools such as G-census and EvaCva, within a historical perspective. Furthermore, it offers a qualitative assessment of what constitutes 'municipal power' as this relates to regional/local revitalization as a means of addressing municipal population decline. Using Goki Shichido as a theoretical framework, this book pays special attention to municipal variations within the same prefecture, presenting a completely unique approach. In combining these two dimensions ofanalyses, the book successfully reveals the impact of municipal power and socio-cultural identity of social capital in the region, from both quantitative and qualitative perspectives at the municipal level. Demography issues in Japan have been receiving increasing attention among researchers given the growing number of declining populations in developed countries, in tandem with rapid aging and low fertility trends. Providing an original and unique contribution to regional population analysis in the fields of regional demography, historical demography and regional population policy, this book shows that the revitalization of the community is vital if Japan is to increase its population, so as to renew a community 'raison d'être'. The book is of interest to scholars of Asian studies more broadly, and to sociologists, demographers, and policymakers interested in population studies, specifically."Providing an informative and vivid overview of the demographic situation of Japan, the author offers excellent suggestions for effective regional policy in confronting a shrinking society. This book presents a unique analysis of the regional variations on small municipal levels, with demographic variables, social indicators and historical identities.¿An original contribution to regional population analysis in the fields of regional population policy, regional demography and historical demography."- Toshihiko Hara, Professor Emeritus, Sapporo City University
