Abstract

Malnutrition in people with liver disease is a challenging issue due to its multifactorial nature, which includes hypermetabolism, increased energy needs, malabsorption, and anorexia. Despite advances in both assessment and management, correct nutritional support is still an often-unanswered need in the care of these patients to avoid poor outcomes. One of the central issues remains how to improve muscolar mass of sarcopenic chronically malnourished individuals with end stage liver diseases and cirrhosis, as only a correct nutritional assessment and subsequent nutritional handling may enhance quality of life and disease outcome. Nutritional management is mandatory in certain inherited metabolic/genetic defects: in these patients specific dietary restrictions/supplementations represent a challenge to guarantee optimal growth and liver health.A nutraceutical approach dealing with hepatoprotective effects of specific nutrients, has been proposed for several chronic liver disease, mainly in obesity related liver disease and alcoholic liver disease. Finally, other challenges are represented by tailored nutritional intervention in improving gut–liver axis dysfunction also in parenteral nutrition/intestinal failure associated liver disease, inflammatory bowel disease, and celiac disease.The purpose of this Special Issue, “Nutrition and Liver Disease”, is to provide novel information and perspectives in the field of nutrition in liver disease and its management.

Abstract

The aim of this Special Issue is to review, understand, and evaluate new and exciting opportunities from the field on regenerative medicine, biomaterials, and stem cell research for the bioengineering of human liver grafts that can be applied for transplantation and personalized treatment of end-stage liver disease.The development of culture conditions for long-term expansion of LGR5+ intestinal stem cells as crypt-villus structures demonstrated the feasibility of deriving complex, organ-like structures in vitro from primary adult tissues, including the liver. Moreover, human pluripotent stem cells (hPSCs) can be applied to generate functionally maturated liver and bile duct epithelial cells.In this Special Issue, we welcome reviews and original papers focussing on hepatic cell sources, including adult hepatic stem cells, organoids, fetal and induced pluripotent stem cells, and primary cells (i.e., hepatocytes, cholangiocytes, and endothelial cells) and how these cells can be applied in tissue engineering strategies to generate implantable and personalized liver grafts. Potential topics include, but are not limited to, the following: liver tissue engineering, liver regeneration, graft repair, liver stem cells and organoids, bio-scaffolds, and 3D printing.We invite you to contribute original research papers, as well as comprehensive reviews, aligned with these themes, to advance and improve the actual state-of-the-art in liver bioengineering and providing new opportunities for the imminent medical problem of organ and tissue shortage for transplantation.

Abstract

Vitamin E is the major lipid-soluble antioxidant in the cell antioxidant system and is exclusively obtained from the diet. In 1922, vitamin E was discovered as a dietary factor essential for reproduction in rats. Meanwhile, vitamin E has revealed many more important molecular properties, such as the scavenging of reactive oxygen and nitrogen species with consequent prevention of the oxidative damage associated with many diseases. In addition, the modulation of signal transduction and gene expression in antioxidant and non-antioxidant manners was shown for vitamin E.This Special Issue highlights some of the recent advances in vitamin E research, showing on the one hand the status quo and providing, on the other hand, new insights into functions and physiological relevance. Thus, the current knowledge of tocochromanol biosynthesis in plants and future challenges regarding the understanding of its regulation are presented. Another paper describes the fate of vitamin E in the human gastrointestinal lumen during digestion. During the metabolism of vitamin E, the long-chain metabolites 13’-hydroxychromanol and 13’-carboxychromanol are formed by oxidative modification of the side-chain. Their occurrence in human serum indicates a physiological relevance. Another paper describes the membrane distribution of α-tocopherol in brain regions of adult rhesus monkeys, also looking for associations between membrane α-tocopherol and the content of polyunsaturated fatty acids.

Abstract

This new book entitled "Non-Alcoholic Fatty Liver Disease Research 2016" covers a selection of recent research topics and current review articles in the field of nonalcoholic fatty liver disease (NAFLD) that have been recently published in a monographic Special Issue of the International Journal of Molecular Sciences (IJMS) journal. NAFLD is an “umbrella” definition that encompasses a spectrum of histopathological liver changes ranging from simple steatosis to nonalcoholic steatohepatitis (NASH) with/without fibrosis, “cryptogenic” cirrhosis and hepatocellular carcinoma. NAFLD has become one of the most common forms of chronic liver disease worldwide and its prevalence is expected to continue rising. It is now becoming increasingly clear that the clinical and economic burden of NAFLD does not only affect the liver, but also affects the risk of developing cardiovascular disease, type 2 diabetes mellitus, colo-rectal neoplasms, chronic kidney disease and other extra-hepatic diseases that have a considerable impact on health-care expenditures. Against this background, further research is needed to better understand the natural history, and the molecular pathogenesis of NAFLD, as well as to elucidate the underlying mechanisms by which NAFLD contributes to the increased cardiometabolic risk, and to disclose novel and effective treatment strategies for this increasingly prevalent and burdensome disease.Some of the leading international researchers in this area expressed a willingness to contribute to this book providing an updated, state-of-the-art view on the aforementioned topics, and also suggesting novel research avenues for NAFLD.

Abstract

Not only developed countries, but also most developing areas of the world, have experienced a surge in obesity prevalence over recent decades. Obesity complications are now among the leading causes of premature mortality, encompassing conditions such as coronary heart disease, stroke, and type 2 diabetes. This places a heavy burden on contemporary healthcare systems. While rodent models have limitations as experimental models of human obesity-related disease, study of rats and mice either spontaneously prone - or resistant - to obesity, or genetically engineered to illuminate underlying mechanisms has yielded key information about the metabolic defects linked to obesity, and their associated diseases. This topic includes both original research studies and reviews of the use of animal studies in specific areas of obesity-related disease. Various methodological approaches are discussed, with evaluation of the extent to which use of animal models has facilitated progress, or, conversely, has proved a cul de sac in investigation of human disease mechanisms. Consideration is also given to future strategies to use such rodent models optimally to enhance comprehension and treatment of pandemic human obesity-related diseases.

Abstract

The aim of this Special Issue focusing on “Nutritional Intake and the Risk of Non-Alcoholic Fatty Liver Disease” is to provide an in-depth overview of the role of the intake of different macro- and micronutrients in the development and progression of non-alcoholic fatty liver disease, as well as in its prevention and treatment. General over-nutrition but also alterations of the dietary pattern (e.g., towards a higher intake of fat, cholesterol, and sugar—and herein especially fructose) are discussed as being critical in the development of non-alcoholic fatty liver disease (NAFLD). However, it has also been suggested that a general reduction of caloric intake and/or modulation of dietary composition, be it in regard to fat or to sugar intake, may have beneficial effects on the liver status in settings of NAFLD. Furthermore, in more recent years, the intake of pre- and probiotics, but also of specific micronutrients or secondary plant compounds, has also been considered a means in the prevention and therapy of this disease. Despite intense research efforts during the last decades, our understanding of the effects of nutritional intake on the development as well as on the prevention and cure of NAFLD is still limited.Providing a better understanding of the effects of diet and especially of specific macro- and micronutrients as well as pre- and probiotics and secondary plant compounds in the context of the development of NAFLD and its progression could lead to novel prevention and therapeutic strategies for this metabolic liver disease. This Special Issue will thus include original research and scientific perspectives on the relationship between NAFLD and dietary constituents that may 1) be involved in the development of the disease and 2) prevent its onset and progression. Mechanistic insights defining the contribution of certain nutritional factors (e.g., macronutrients like fat and sugar but also micronutrients and secondary plant compounds as well as pre- and probiotics) to the occurrence and management of NAFLD will improve our understanding of the disease and eventually lead to the development of universally accepted prevention and therapeutic strategies.

Abstract

Lymphocytes constantly survey the lymph nodes in search for potential infection by a pathogen. They enter the afferent lymphatic vessel that serves as a conduit to transport the motile lymphocytes to the draining lymph node. Lymphatic vessels (LVs) are present in most vascularized tissues. They are traditionally regarded as passive conduits for soluble antigens and leukocytes. Afferent LVs begin as blind ended capillaries, which give rise to collecting vessels that merge and connect with draining lymph nodes (dLNs). Initial lymphatic capillaries are composed of Lymphatic Endothelial Cells (LECs) connected by discontinuous cell junctions, which join to form larger collecting lymphatic vessels, and ultimately feed into the LN subcapsular sinus. Within the LN, LECs are localized to the subcapsular, cortical, and medullary sinuses, where they interact with incoming and exiting leukocytes. LECs, and in general LN stromal cells, have emerged in the recent years as active players in the immune response. In support to this,studies have shown that the immune response generated during inflammation and under pathologic conditions is accompanied by modeling of the LVs and generation of new lymphatics, a process known as lymphangiogenesis. These facts strongly suggest that LECs and stromal LN cells in general, are not inert players but rather are part of the immune response by organizing immune cells movement, exchanging information and supplying survival factors. The purpose of this research topic is to review the role of the LECs during immune homeostasis and cancer. Considering the critical role of lymphangiogenesis in many pathologies like chronic and acute inflammation, autoimmunity, wound healing, graft rejection, and tumor metastasis, it is important to understand the molecular mechanisms that govern the cross talks between the LECs and immune cells during homeostasis and inflammation.

Abstract

Micro-bioreactors offer unique opportunities to study biological systems under fluidic conditions. The concept of micro-bioreactors suggests that biological reaction conditions on a large scale can be scaled down to micro-volumes while maintaining performance and functionality. Models and operation principles can be simulated at a smaller scale, either by scaling down organs in the human body, or using bioreactors for the production of biologics. This book highlights these issues with a strong focus on new engineering design. The initial chapters cover the conceptual design of microbioreactors and organ-on-chips, and the role of microbioreactors in tissue engineering for clinical and therapeutic targets. Two chapters are dedicated to microbioreactors for implementing tumor models. Other chapters discuss three-dimensional models for hepatic and cardiac cells for toxicity testing and drug evaluation. Finally, the design of organ chips for cartilage scaffolds and the integration of sensors are covered in separate chapters. We believe the book will have substantial value for researchers active in bioreactor engineering, drug development and cell physiology, as well as readers interested in these topics.

Abstract

Identification and development of cancer biomarkers and targets have greatly accelerated progress towards precision medicine in oncology. Studies of tumor biology have not only provided insights into the mechanisms underlying carcinogenesis, but also led to discovery of molecules that have been developed into cancer biomarkers and targets. Multi-platforms for molecular characterization of tumors using next-generation genomic sequencing, immunohistochemistry, in situ hybridization, and blood-based biopsies have greatly expanded the portfolio of potential biomarkers and targets. These cancer biomarkers have been developed for diagnosis, early detection, prognosis, and prediction of treatment response. The molecular targets have been exploited for anti-cancer therapy and delivery of therapeutic agents. This Special Issue of Biomedicines focuses on recent advances in the discovery, characterization, translation, and clinical application of cancer biomarkers and targets in malignant diseases of the digestive system. The goal is to stimulate basic and translational research and clinical collaboration in this exciting field with the hope of developing strategies for prevention and early detection/diagnosis of cancer in digestive organs, and improving therapeutic and psychosocial outcomes in patients with these malignant diseases.
