A preventative medicine physician and staff writer for The Atlantic explains the surprising and unintended effects of our hygiene practices in this informative and entertaining introduction to the new science of skin microbes and probiotics.
 
Keeping skin healthy is a booming industry, and yet it seems like almost no one agrees on what actually works. Confusing messages from health authorities and ineffective treatments have left many people desperate for reliable solutions. An enormous alternative industry is filling the void, selling products that are often of questionable safety and totally unknown effectiveness.

In Clean, doctor and journalist James Hamblin explores how we got here, examining the science and culture of how we care for our skin today. He talks to dermatologists, microbiologists, allergists, immunologists, aestheticians, bar-soap enthusiasts, venture capitalists, Amish people, theologians, and straight-up scam artists, trying to figure out what it really means to be clean. He even experiments with giving up showers entirely, and discovers that he is not alone.

Along the way, he realizes that most of our standards of cleanliness are less related to health than most people think. A major part of the picture has been missing: a little-known ecosystem known as the skin microbiome—the trillions of microbes that live on our skin and in our pores. These microbes are not dangerous; they’re more like an outer layer of skin that no one knew we had, and they influence everything from acne, eczema, and dry skin, to how we smell. The new goal of skin care will be to cultivate a healthy biome—and to embrace the meaning of “clean” in the natural sense. This can mean doing much less, saving time, money, energy, water, and plastic bottles in the process.

Lucid, accessible, and deeply researched, Clean explores the ongoing, radical change in the way we think about our skin, introducing readers to the emerging science that will be at the forefront of health and wellness conversations in coming years.

Transfusion Medicine, Apheresis, and Hemostasis: Review Questions and Case Studies is the collaborative effort that spanned a time period of 2 years and included 50 experts, many whom are national leaders in their respected fields. It also represents the passion and privilege we feel to teach the next generation of physicians in Transfusion Medicine and Apheresis. The main goal for this book is to help the readers build a solid foundation of both basic and advanced conceptual knowledge to prepare for the American Board of Pathology (ABP) certification exam in Transfusion Medicine. This book is not intended to be a substitute for textbooks, original research or review articles, and/or clinical training. Further, since the field of medicine, both from a scientific and regulatory perspective, rapidly changes, the readers are advised to continuously update their knowledge by attending national meetings and reading clinical journals. To equip the readers with the basic knowledge in critical reading and data analysis, which is an essential skill in daily medical practice, a novel chapter titled "Data Interpretation in Laboratory Medicine" was included in this book. In this chapter, the readers are asked to make logical conclusions based on the given data and/or statistical results. Moreover, there is also a chapter on "Practical Calculations in Transfusion Medicine, Apheresis, and Hemostasis" to help consolidate all the necessary formulas commonly used in daily practice for easy reference. These chapters are unique to our book and will not be found in any other currently on the market. All of the questions in this book were originally created by the authors of each chapter. Each question can either be standalone or part of a case scenario representing challenge cases in Transfusion Medicine, Apheresis, and Hemostasis. These questions often represent both rare and common clinical scenarios that the authors have seen during their clinical practice. Each question is then followed by 5 possible answers, with only one being correct (or the best answer). After the question, there is a conceptual explanation followed by a more factual explanation of the right and wrong answers. We gave the individual authors the freedom to choose how they explained the wrong answer choices. Some authors chose to be more direct (e.g. Answer A is incorrect because...), while other authors chose a more conversational style (e.g. Human resources (answer A) includes staffing, selection, orientation, training, and competency assessment of employees). This format is designed to help the student linking the conceptual and factual knowledge together to form a solid foundation for use in clinical practice. At the end of each chapter, there is a list of articles and textbooks that will prove useful to the motivated student who wishes to become an expert in the field. Another special feature to our textbook is the presence of a pre-test and post-test, which are provided to help the readers with self-assessment. As stated above, the main focus of this book is to help the readers preparing for the ABP certification exam in Transfusion Medicine. However, due to the interdisciplinary nature of the field of Transfusion Medicine, Apheresis, and Hemostasis, we believe that this book is also beneficial to and can be used by all clinicians involved in the management of complex transfusion, apheresis, and hemostasis issues, such as hematologists, anesthesiologists, surgeons, and critical care physicians. We further believe that it is a helpful guide for these specialists to prepare for their own specialty certification exam, when the topics are related to Transfusion Medicine, Apheresis, and Hemostasis.

Plant innate immunity is a potential surveillance system of plants and is the first line of defense against invading pathogens. The immune system is a sleeping system in unstressed healthy plants and is activated on perception of the pathogen-associated molecular patterns (PAMP; the pathogen’s signature) of invading pathogens. The PAMP alarm/danger signals are perceived by plant pattern-recognition receptors (PRRs). The plant immune system uses several second messengers to encode information generated by the PAMPs and deliver the information downstream of PRRs to proteins which decode/interpret signals and initiate defense gene expression. This book describes the most fascinating PAMP-PRR signaling complex and signal transduction systems. It also discusses the highly complex networks of signaling pathways involved in transmission of the signals to induce distinctly different defense-related genes to mount offence against pathogens.

Originally published in 1928 as part of the Cambridge Comparative Physiology series, this book examines the importance of cilia in the lives of many invertebrate animals. Gray demonstrates how cilia, not muscle fibres, often play the dominant role as organs of contraction and locomotion and explains how ciliated surfaces are co-ordinated. This book will be of value to anyone with an interest in the history of science.

Fungi produce many chemically diverse secondary metabolites whose biological roles largely remain elusive. Within the increasing number of sequenced fungal genomes several important genes involved in secondary metabolite formation have been identified. Most of these genes are clustered and their coordinated transcription is controlled in a complex way by both narrow pathway-specific regulators as well as broad global transcription factors responsive to environmental cues. In recent years it was discovered many of the newly identified gene clusters are silent under laboratory conditions suggesting that the biosynthetic potential of fungi is far from being exploited. Besides identifying novel bioactive metabolites from still unexplored sources, the activation of these gene clusters by several approaches may result in the discovery of new substances with antibiotic and pharmaceutical benefits. This book covers recent advances in the field of fungal secondary metabolisms ranging from methodologies to biological aspects and will include the latest knowledge on fungal molecular biology, genomics, and metabolomics. With the related volume by Professor Juan-Francisco Martin, where the most relevant and well-studied fungal secondary metabolites are compiled, this book provides a comprehensive overview of the state-of-the-art of research on fungal secondary metabolites.

This collection of papers includes some of the presentation given at the International congress of Plant Pathology held in Beijing in 2013 in the session of Recent Development in Postharvest Pathology. Fruit production for human consumption is an important part of the market economy. Any waste during to spoilage and pest infestation, in the field and the postharvest phase, results in significant economic losses which are more pronounced as the losses occur closer to the time of produce sale. Careful handling of perishable produce is needed for the prevention of postharvest diseases at different stages during harvesting. Handling, transport and storage in order to preserve the high quality produce. The extent of postharvest losses varies markedly depending on the commodities and country estimated to range between 4 and 8% in countries where postharvest refrigeration facilities are well developed to 30% where facilities are minimal. Microbial decay is one of the main factors that determine losses compromising the quality of the fresh produce. For the development of an integrated approach for decay management, cultural, preharvest, harvest and postharvest practices should be regarded as essential components that influence the complex interactions between host, pathogen, and environmental conditions. Orchards practices including preharvest fungicide applications can also directly reduce the development of postharvest fruit decay. Among postharvest practices, postharvest fruit treatments with fungicide are the most effective means to reduce decay. Ideally, these fungicides protect the fruit from infections that occur before treatment, including pathogen causing quiescent infections, as well from infection that are initiated after treatment during postharvest handling, shipment and marketing. The implementation of these alternatives techniques often requires modifying currently used postharvest practices and development of new formulation for their applications. The present chapters deal with the newest report related to postharvest pathology in the world.

Reports on the emergence and prevalence of resistant bacterial infections in hospitals and communities raise concerns that we may soon no longer be able to rely on antibiotics as a way to control infectious diseases. Effective medical care would require the constant introduction of novel antibiotics to keep up in the "arms race" with resistant pathogens. This book closely examines the latest developments in the field of antibacterial research and development. It starts with an overview of the growing prevalence of resistant Gram-positive and Gram-negative pathogens, including their various resistance mechanisms, prevalence, risk factors and therapeutic options. The focus then shifts to a comprehensive description of all major chemical classes with antibacterial properties, their chemistry, mode of action, and the generation of analogs; information that provides the basis for the design of improved molecules to defeat microbial infections and combat the emerging resistances. In closing, recently developed compounds already in clinical use, those in preclinical or first clinical studies, and a number of promising targets to be exploited in the discovery stage are discussed.

This Brief provides a comprehensive overview of Trypanosoma cruzi, a parasite that is traditionally considered as exclusively vectorborne, but can be foodborne, and may lead to outbreaks of Chagas disease in consumers. The characteristics of Trypanosoma cruzi and the clinical effects of the disease are covered, including documented outbreaks, regional patterns, and epidemiology. The various transmission routes are outlined, but with specific focus on foodborne transmission. A major emphasis of this text is contamination of fruit juices with Trypanosoma cruzi in, a transmission vehicle with increasing significance in the spread of this parasite. Also outlined is the difficulty of establishing a protocol for detection in food samples. Results on survival of Trypanosoma cruzi in food matrices is considered, as well as current risk assessment procedures and regulations. Different approaches to preventing transmission, including inactivation and decontamination are introduced, but also the importance of targeted educational initiatives, and also with a focus on future detection, prevention, and prevention of contamination of foods with this parasite.

Since their discovery in 1869, the dictyostelids have attracted the attention of scientists in a wide variety of fields. This interest has stemmed from their peculiar lifestyle and developmental properties, which were shaped by the evolutionary forces that generated multicellularity during eukaryotic evolution. More recently, the dictyostelids have gained attention due to the striking similarities found at the genomic, cellular and biochemical levels with human cells, which has propelled the species Dictyostelium discoideum to become a model system for biology and medicine in many laboratories. This book covers the latest advances in our knowledge of these extraordinary organisms with topics spanning from their evolutionary history, ecology and diversity to the recent discoveries regarding their cellular and molecular biology.

Microbes and microbiology are seldom encountered in philosophical accounts of the life sciences. Although microbiology is a well-established science and microbes the basis of life on this planet, neither the organisms nor the science have been seen as philosophically significant. This book will change that. It fills a major gap in the philosophy of biology by examining central philosophical issues in microbiology. Topics are drawn from evolutionary microbiology, microbial ecology, and microbial classification. These discussions are aimed at philosophers and scientists who wish to gain insight into the basic philosophical issues of microbiology.

Topics presented include how symbiosis starts on the molecular level; chemical signaling in mycorrhizal symbiosis; genomic and functional diversity of endophytes; nitrogen fixation; nutrient uptake and cycling; as well as plant protection against various stress conditions. Further, the use of beneficial microorganisms as biopesticides is discussed, particularly the application of Plant Growth Promoter Rhizobacteria (PGPR) in agriculture with the aim to increase yields.

Bioethanol has been recognized as a potential alternative to petroleum-derived transportation fuels. Even if cellulosic biomass is less expensive than corn and sugarcane, the higher costs for its conversion make the near-term price of cellulosic ethanol higher than that of corn ethanol and even more than that of sugarcane ethanol. Conventional process for bioethanol production from lignocellulose includes a chemical/physical pre-treatment of lignocellulose for lignin removal, mostly based on auto hydrolysis and acid hydrolysis, followed by saccharification of the free accessible cellulose portions of the biomass. The highest yields of fermentable sugars from cellulose portion are achieved by means of enzymatic hydrolysis, currently carried out using a mix of cellulases from the fungus Trichoderma reesei. Reduction of (hemi)cellulases production costs is strongly required to increase competitiveness of second generation bioethanol production. The final step is the fermentation of sugars obtained from saccharification, typically performed by the yeast Saccharomyces cerevisiae. The current process is optimized for 6-carbon sugars fermentation, since most of yeasts cannot ferment 5-carbon sugars. Thus, research is aimed at exploring new engineered yeasts abilities to co-ferment 5- and 6-carbon sugars. Among the main routes to advance cellulosic ethanol, consolidate bio-processing, namely direct conversion of biomass into ethanol by a genetically modified microbes, holds tremendous potential to reduce ethanol production costs. Finally, the use of all the components of lignocellulose to produce a large spectra of biobased products is another challenge for further improving competitiveness of second generation bioethanol production, developing a biorefinery.
