Once the first cell arose on Earth, how did genetic diversity arise if DNA replication and cell division generate exact copies? The answer is that neither process is perfect and that changes do occur at each step. Some changes are small and subtle while others are large and dramatic. As DNA mutates, evolution of a population takes place. But when can someone determine if a single species has changed enough to be considered two separate species? How is a species defined and is this definition useful in the real world? Real biological data will be examined to confront and an-swer these questions. Finally, the book examines an example of evolution that takes place in humans on a regular basis-the mammalian immune system. White blood cells evolve rapidly to confront any substance that enters a body and is perceived as a threat. With each exposure, these cells get better and better at neutralizing the threat.

Authoritative resource presenting techniques and technologies to sustainably neutralize environmental contamination in aquatic plants, microorganisms, and more Two thirds of the Earth is covered with aquatic habitats that play a key role in stabilizing the global environment and providing a wide variety of services to increasing human needs. Nevertheless, anthropogenic activities are rapidly destroying the quality of both fresh and marine waters globally, due to excessive use of chemicals, fertilizers and pollution from suburban and industrial areas eventually making their way into the aquatic world. Aquatic Contamination: Tolerance and Bioremediation presents the broader spectrum of biological applicability of microbes with better understanding of cellular mechanisms for remediation of aquatic contaminants. The book also focuses on practices involved in molecular and genetic approaches, necessary to achieve targets of bioremediation and phytoremediation to solve global water contamination problems. Such approaches pave the way for the utilization of biological assets to design new, efficient, and environmentally sound remediation strategies by inculcating genomic techniques at cellular and molecular levels with model assessment. Aquatic Contamination provides a comprehensive background for readers interested in all perspectives of the contamination of aquatic environs. It covers various research aspects which are being carried out globally to understand simulation models in the assessment of xenobiotics, role of genomics, transgenic plants, and microbial enzymes for degradation and removal of toxic substances in aquatic environs. Key features include: Extensive coverage of interactions between plant, metals and microbes including the influence of biotic and abiotic factors Comprehensive discussion of the details of molecular mechanisms from assimilation to detoxification levels Exploration of the enzymatic approaches of potential plants acting as hyper-accumulators for contaminants in aquatic environs Details of sustainable tools such as transgenic plants for the manipulation of important functional microbial genes to achieve higher certainty of bioremediation Details of advances in tools and models like micro-arrays and simulation models for the complete assessment of xenobiotic compounds from cellular to degradation hierarchies Aquatic Contamination: Tolerance and Bioremediation will be substantially helpful to environmentalists, microbiologists, biotechnologists and scientists, providing essential information on various modern technologies for the remediation of contaminants in aquatic ecosystems.

Cells are the building blocks of all living things. They are called "cells" because Robert Hooke, the person who discovered the cells when looking under the microscope thought that it looked like the "empty rooms" of a monastery where monks used to sleep in.

Biology is the study of living organisms and the research of the science behind living things. Biology is the core that unites all other disciplines and sub-disciplines of biological science. This starts with the understanding of the cell. Hence, the study of biology is vital for our children.

This book, "Cells For Kids" is a book designed for children with diagrams so that they can learn everything about animal and plant cells from the start. As parents, we must ingrain their minds and awaken their curiosity so that they can be ready for this complex and rapidly evolving subject area.

Most biology books, be it for children or adults start with a chapter on the cell. It is here that all biological processes take place. Hence it is vital that we as parents, teach our children about the cell as early as possible. Some may be able to learn while some may not but at least it's a step in the right direction.

I wrote this book for my own children and I can see that they are now curious about what a cell is and what exactly does it does? Half of my job is done; this will save me a lot of heartache later on when I am trying to trying to teach them biology. My ultimate aim would be to get them to study science when they grow up and this book would be one of their stepping stones. Study of biology will prepare children for a range of careers where they can make a difference in the world.

Here's what's covered in this book about cells. I have included questions after some chapters for parents to ask to ensure kids are learning before moving on to the next chapter. There is a quiz at the end of the book.

The chapters:

1. What is a cell? (This chapter defines what a cell is)

2. Who discovered the cell? (Describes exactly how Robert Hooke discovered the cell and what he saw under the microscope)

3. What are cells made of? (Describes what the cell is made of - organelles and cytoplasm)

4. Why cells are mostly made of water? (A good question and a difficult one to answer)

5. How big is a cell? (Cells come in different shapes and sizes, get to learn the size of the cell)

6. How many cells are in the human body? (The body is made of cells and children will learn how many cells we have)

7. How many different types of cells are there? (Learn about the different types of cells namely; eukaryotic and prokaryotic cells)

8. The animal cell (Learn about the animal cell and its various structures with a labelled diagram)

9. Parts and organelles of animal cells (Describes each organelles of the animals cells)

10. The plant cell (Learn about plant cells with a labelled diagram)

11. The parts and organelles of plant cells (Describes parts and organelles of the plant cells)

12. Animal cells and plant cells - The Difference (Goes through the many differences between the animal and plant cells)

13. What are tissues, organs and organ systems? (Cells form tissues, which then form organs and then organs systems)

14. Cellular division - Cell cycle (There are two types of cells (1) Mitosis and (2) Meiosis)

15. 10 facts about the cell (Some facts about the cell)

16. Quiz - What can you remember? (A quiz at the end of the book)

This book examines four examples of animal physiology that illustrate emergent properties in whole organisms. The first example shows how mammals coordinate the activity of all their cells using a daily rhythm. The second case explains an apparent contradiction that happens every time a woman gets pregnant and delivers a healthy baby-how the immune system tolerates a foreign tissue such as the fetus. The next case study in this book shows how bodies regulate the amount of fat using a complex in-teraction of proteins that function as a lipostat, a self-regulating fat maintenance system. Finally, the book provides an understanding of why some species live long lives while others die after very short lives, and under what conditions each situation is favored. What is evolutionarily adaptive about death? These four case studies provide sufficient evidence to understand how animals regulate many of their own metabolic functions.

This comprehensively revised second edition of "Computational Systems Biology" discusses the experimental and theoretical foundations of the function of biological systems at the molecular, cellular or organismal level over temporal and spatial scales, as systems biology advances to provide clinical solutions to complex medical problems. In particular the work focuses on the engineering of biological systems and network modeling.
Logical information flow aids understanding of basic building blocks of life through disease phenotypesEvolved principles gives insight into underlying organizational principles of biological organizations, and systems processes, governing functions such as adaptation or response patternsCoverage of technical tools and systems helps researchers to understand and resolve specific systems biology problems using advanced computationMulti-scale modeling on disparate scales aids researchers understanding of dependencies and constraints of spatio-temporal relationships fundamental to biological organization and function.

Whether it is to look to the past in search of their origins, analyze their present activity, particularly digital, or to think about the effects of their actions on the future, 21st century humans regularly question their traces . Collective questions and technical progress offer new resources which, in turn, raise the problems of traces. In order to reveal the difficulties posed by the unanalyzed trace, this book proposes a journey through different contexts. Along the way, intellectuals (including Bateson, Barthes, Bourdieu, Derrida, Goffman, Peirce, Ricoeur, Varela, Thompson, Watsuji and Watzlawick) and trace professionals (such as police officers or computer scientists) shed light on the background to this veritable odyssey. This didactic book presents a contemporary exploration of the fundamental nature of the trace via the new French paradigm of the Ichnos-Anthropos ( Homme-trace ) and its corollary, the corps-trace .

Pulmonary hypertension is a life-threatening disease with no known cure. Here we provide a concise yet comprehensive review of the current knowledge about the pathophysiology of pulmonary hypertension (PH). The underlying signaling mechanisms involved in pulmonary vascular remodeling and the exaggerated vascular contractility, two characteristic features of pulmonary hypertension, are discussed in depth. The roles of inflammation, immunity, and right ventricular function in the pathobiology of pulmonary hypertension are discussed. The epidemiology of the five groups of pulmonary hypertension (World Health Organization classification; Nice, 2013) is also briefly described. A clear understanding of our current knowledge about the pathogenesis of PH is essential for further exploration of the underlying mechanisms involved in this disease and for the development of new therapeutic modalities. This book should be of interest to researchers and graduate students, both in basic research and in clinical settings, in the fields of pulmonary vascular biology and pulmonary hypertension.
