Trends in Pharmaceutical and Food Sciences I

Abstract

Trends in Pharmaceutical and Food Sciences I is the first issue of an open access E-book devoted to scientific and technical research that covers the entire spectrum of drug and food research, including medicinal chemistry, pharmacology, drug delivery, microbiology and biochemical studies, as well as relevant developments in nutrition, food safety and analytical innovation. The first chapter, Different techniques to detect G protein coupled receptor heteromers, describes state of the art techniques based in biophysical principles applied to detect oligomeric aggregates formed by G-protein coupled receptors in the cell membrane, and describes how the knowledge generated can be applied to design new compounds for the treatment of neurological and mental diseases. Obesity has become a worldwide problem and it is well known that causes and exacerbates many health problems by promoting profound changes in physiological functions. Chapter 2, Analysis of the role of diet in the appearance of neurodegenerative processes, reviews the consequences of these metabolic alterations while considering their effects in the development of Type 2 Diabetes Mellitus, and their role in the appearance of cognitive impairments such as the sporadic forms of Alzheimer’s disease. The development of new cultivars facing climate change is an issue of great interest for the agrochemical industry and can be approached in different ways. Chapter 3, Arabidopsis Thaliana A Model for the Study of Plant Speciation, reviews different aspects of the plant immune system and the different layers of the plant immune response and signaling. The emerging field in plant research that studies how soil microbiota influences plant basic mechanisms is also discussed. Chagas disease is endemic in Latin America, but recently and due to human migrations, it is becoming a global health problem. In chapter 4, Trypanosoma cruzi infection diagnosis: New insights, challenges and perspectives, a group of experts from several institutions describe the different techniques that can be used for the serological diagnosis of the infection and the characterization of Trypanosoma cruzi, discuss the advantages and drawbacks of each method and propose improvements that would entail important savings for health institutions. Chapter 5, Nutrients, Control of Gene Expression and Metabolic Homeostasis, focuses on the molecular mechanisms that control metabolism by means of regulating gene expression in response to dietary inputs, to design new therapeutic strategies based on nutritional interventions against metabolic diseases. In this context, involvement of FGF21 hormone in the regulation of lipid metabolism during amino acid starvation is described, thus reinforcing its important role as an endocrine factor in coordinating energy homeostasis under a variety of nutritional conditions. This raises the possibility of dietary modulation of circulating levels of FGF21 as an alternative approach to its pharmacological administration. Biodegradable polymeric nanoparticles encapsulating neuroprotective drugs have enormous potential to treat neurodegenerative diseases, including Alzheimer´s disease and glaucoma. Recent advances in the field are described in chapter 6, Polymeric nanoparticles for the treatment of neurodegenerative diseases: Alzheimer’s disease and glaucoma, specifically the preparation of engineered polymeric nanoparticles with attached peptides or antibodies to increase their bioavailability, favoring their transport through the blood brain barrier and the blood retinal barrier, avoiding at the same time possible drug adverse and toxic effects. The last chapter, Pentacyclic triterpenes in table olives: Determination of their composition and bioavailability by LC-M, is a review on the pentacyclic triterpenes contained in table olives, natural compounds of enormous interest due to their beneficial effects on human health, including hepatoprotective, anti-diabetic, antiviral, cardioprotective and antitumor activities. Authors describe a selective and sensitive LC–MS method for the simultaneous determination of the main triterpenic compounds present in Olea europaea L. This opens the possibility to bioavailability studies after consumption of different foods, or administration of plants widely used in traditional medicine, with the aim of studying in depth the beneficial effects of these compounds in human beings. We hope that this new volume will attract the interest of all the scientific community, especially those working in the fields of pharmaceutical, medical, biological, chemical and food sciences.
