Abstract

Foodborne disease like salmonellosis and toxoplasmosis are amongst the most significant causes of hospitalization in the U.S. and globally. Gastrointestinal infections alter gut microbiomes and increase permeability to toxins. Various invasions by microbial, fungal, viral and parasitic agents stimulate inflammation, a defensive mechanism of the body’s immune system. Other stimuli include environmental stimuli, oxidative stress, aging and the physiological process. A long-lasting, persistent and excessive inflammatory response is a significant risk factor for developing various chronic inflammatory and infectious diseases.Different nutritional and dietary life styles, whether poor or lacking essential nutritional elements, as well as excess intake, can result in inflammatory complications and loss of function. Nutritional deficiency is linked with several infectious and inflammatory diseases as a cause or consequence. For instance, protein deficiency was reported in orphanages to provoke microbial and fungal complications including Pneumocystis pneumonia. Similarly, protein deficiency is a tell-tale sign of several parasitic diseases. Studies indicate that nutrients, such as amino acids, oligosaccharides, and short-chain fatty acids exert inhibitory and anti-inflammatory functions. These investigations help to understand nutritional contributions to the prevention, treatment and taming of certain inflammatory and infectious diseases. Infectious and inflammatory complications go hand-in-hand with malnutrition.The purpose of this Special Issue is to publish related new, basic and translational findings and clinical trials in this area. Other investigations or review articles were sought to link infectious and inflammatory diseases with nutrients. In addition, novel diagnostic, preventive and therapeutic modalities were invited to aid the development of nutritional strategies for the treatment and/or prevention of inflammation and infection. Original reviews were of particular interest to advance our understanding of signaling pathways, and the molecular and biochemical mechanisms behind the effects of nutrients on inflammatory and infectious diseases.

Abstract

The role of many phytochemicals in the modulation of the carcinogenesis process has been well documented by combining in vitro and animal studies, as well as epidemiological evidence. When acting in synergy, phytochemicals exert potential anti-cancer properties and much progress has been made in defining their many biological activities at the molecular level. However, an interesting feature in the field of phytochemicals and cancer is the role of some phytochemicals in promoting cancer development. This Special Issue of Toxins aims to provide a comprehensive look at the contribution of dietary and non-dietary phytochemicals to cancer development and at the molecular mechanisms by which phytochemicals inhibit or promote cancer. These aspects are extremely useful for the definition of efficient preventive measures against cancer.

Abstract

Over the last few years, polyphenol has received a great deal of attention due to their potential beneficial effects on human health. Widely contained in foods commonly consumed in all populations worldwide, polyphenols represent an attractive explanation of the beneficial effects, not only of fruits and vegetables, characteristic components of healthy dietary patterns, but also of other plant-derived foods, such as tea, coffee, and cocoa, which only recently have been exploited as being beneficial for humans. In addition to the numerous biological properties, polyphenols have been indicated as being responsible for a decreased risk of metabolic disorders, cardiovascular disease, and certain cancers. The book addresses original research and reviews of literature concerning polyphenol-rich foods and human health.

Abstract

Ascorbic acid is a small, simple, water soluble molecule, synthesised by most plants and animals, with the exception of humans and some animal species due to mutations in the gene encoding the terminal enzyme in the biosynthetic pathway. For humans, it is thus a vitamin (vitamin C) that must be obtained from the diet, with complete deficiency resulting in the fatal disease scurvy. Many functions have been attributed to this fascinating molecule and, despite nearly 90 years of research since its discovery, new roles are still being uncovered, including recent discoveries that it acts as a regulator of epigenetic marks and transcription factors (1). In this volume we begin with a review by Michels and Frei on specific factors that need to be taken into consideration when carrying out vitamin C research. Translational research normally comprises a progression from in vitro/cell culture studies to animal models and finally to clinical trials. At each of these stages, there are requirements specific to vitamin C research that need to be integrated into study designs and this review describes these in detail. [...]

Abstract

Antimicrobial peptides (AMPs) are gene-encoded, ancient (and important) mediators of innate host defense that exert direct or indirect antimicrobial action as well as possessing other important biologic activities (e.g., neutralization of endotoxin and anti-biofilm action) that help to protect vertebrates, invertebrates and plants from invading pathogens. While the emergence of multi-antibiotic resistant pathogens (and the desperate need to develop new anti-infectives) has been a recent force driving the field, interest in AMPs has an earlier origin in studies of how phagocytes kill bacteria by oxygen-independent processes. AMPs responsible for such killing of microbes by rabbit and human neutrophils were later purified by Ganz, Selsted and Lehrer, which they termed defensins; at the time of this writing, literally thousands of defensin-based publications can be found in the scientific literature! The initial reports on defensins and the earlier report by Boman’s group on the purification and action of an insect AMP represented a historical and defining point for the AMP field as they, in hindsight, demanded the recognition of AMP research as a unique discipline that has important linkages to other important fields of medicine, especially those of microbiology, infectious diseases and immunology. On a personal note, I remember conferences on phagocytes and host defense in the early 1980s where the topic of AMPs was relegated to one short session in a five day period! Now, we have hundreds of international “AMPologists” with expertise in chemistry, biochemistry, molecular and structural biology, cell biology, microbiology, pharmacology, or medicine who have built their research careers around AMPs and can now attend international conferences dedicated to advances in AMP research.

Abstract

The role of major dietary omega-3 fatty acids (Ω-3; α-linolenic acid, eicosapentaenoic acid and docosahexaenoic acid) in human health has generated enormous scientific interest and many controversies in recent years. Due to a growing number of studies with conflicting or even negative clinical results, the former “hype” of Ω-3 thought to be beneficial in many aspects of human health regardless of the physiological and clinical preconditions is now being critically re-evaluated, especially with respect to the potential role of Ω-3 fatty acid supplementation in preventing a variety of diseases and clinical conditions. This critical view reflects the complex interaction of Ω-3 with cell membranes and their integrated proteins mediating signal transduction, transport systems, and other processes. Moreover, Ω-3 are precursors of bioactive metabolites, such as eicosanoids, lipoxins, resolvins, protectins, maresins, and nitrolipids that influence several physiological and pathophysiological processes and their full spectrum of effects are only beginning to be defined. Finally, physiological and pathophysiological conditions as well as concomitant pharmacological treatments may influence the specific and non-specific actions of Ω-3 supplementation.This Special Issue of the Journal of Clinical Medicine will emphasize the role and biological interactions of Ω-3 with regard to cancer, psychiatric disorders, metabolic disorders and nutrition and will also reflect on some basic molecular and cellular mechanisms.

Abstract

Accumulating evidence suggests that not all obese subjects are at increased cardiometabolic risk and that the “metabolically healthy obese” phenotype may exist in the absence of metabolic abnormalities. Limited data regards the determinants of metabolically healthy obesity exist, particularly in relation to genetics, dietary and lifestyle behaviours. In light of the current obesity epidemic, it is clear that current “one size fits all” approaches to tackle obesity are largely unsuccessful. Whether dietary, lifestyle and/or therapeutic interventions, based on stratification of obese individuals according to their metabolic health phenotype, are more effective remains to be seen, with limited and conflicting data available. This book includes original research articles and reviews of the scientific literature that contribute to our understanding of the role of clinical, biological, genetic, and environmental factors in metabolically healthy and unhealthy obesity.

Abstract

Wounds are a largely unrecognized, spiraling epidemic that affect millions of people world-wide. They are complex and involve temporal and spatial involvement of many different cell types and tissue processes. Recent advances in our understanding of wound repair and regeneration, as well as the many novel and exciting approaches aimed at healing chronic/acute wounds and reducing scar formation, make this a pertinent time for a Special Issue aimed at overviewing this important field. The goal of this book is to provide a summary of the field, describe its impact, as well as introduce the recent advances in understanding the mechanisms that underpin wound healing and scar formation. The articles include in this book highlight new developments in therapeutic approaches for wound repair including the use of nanomedicine and biomaterials to deliver cells and/or drugs to promote healing. Cellular responses that underpin angiogenesis, inflammation, proliferation and remodeling, as well as advances in cytoskeletal interactions in keratinocytes and fibroblast cell functions. Wound remodeling and scar formation including the roles of growth factors, cytokines and stem cells are included.
