Abstract

Catheter ablation is a major treatment for atrial tachycardias. Hereby, the precise monitoring of the lesion formation is an important success factor. This book presents computational, wet-lab, and clinical studies with the aim of evaluating the signal characteristics of the intracardiac electrograms (IEGMs) recorded around ablation lesions from different perspectives. The detailed analysis of the IEGMs can optimize the description of durable and complex lesions during the ablation procedure.

Abstract

The purpose this thesis is to study the effect of fermentable feed ingredients on the intestinal health of weaned piglets via an in vitro fermentation model combined with an ex vivo model on intestinal explants. &#13;&#13;This work will focus on two different pools of ingredients. The first pool will focus on chicory, it’s corresponding by-products and purified fractions. The same principle will be applied to the second pool that is composed out of oat and barley. &#13;&#13;All the feed ingredients are going to be tested by an in-vitro model combined with an ex-vivo model. The aim of those experiments is to determine whether barley, oat, chicory or by-products could have a close effect on intestinal health corresponding to their purified fraction. &#13;&#13;First, an in vitro fermentation will be performed using weaned piglets' feces. The aim is to measure the resulting gas production and to collect fermentation fluids. Based on these fermentation juices, we can measure the concentration in volatile fatty acids by HPLC but also estimate the relative amount of butyrogenic species by PCR. These fermentation juices will also be used during the ex vivo procedure. &#13;&#13;The ex vivo model will consist in inducing an inflammation (via LPS of E. Coli) in weaned piglets' intestinal explants and see if the applied fermentation juices are able reduce inflammation. &#13;For that, cytokines, tight junctions and mucins mRNA levels will be analysed by qRT-PCR. &#13;&#13;Based on the in vitro - ex vivo model analyses, we can thereafter select which fermentable feed ingredients are the most suitable for the in vivo trial on weaned piglets.

Abstract

The use of lipid-based nanosystems, including lipid nanoparticles (solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC)), nanoemulsions, and liposomes, among others, is widespread. Several researchers have described the advantages of different applications of these nanosystems. For instance, they can increase the targeting and bioavailability of drugs, improving therapeutic effects. Their use in the cosmetic field is also promising, owing to their moisturizing properties and ability to protect labile cosmetic actives. Thus, it is surprising that only a few lipid-based nanosystems have reached the market. This can be explained by the strict regulatory requirements of medicines and the occurrence of unexpected in vivo failure, which highlights the need to conduct more preclinical studies.Current research is focused on testing the in vitro, ex vivo, and in vivo efficacy of lipid-based nanosystems to predict their clinical performance. However, there is a lack of method validation, which compromises the comparison between different studies.This book brings together the latest research and reviews that report on in vitro, ex vivo, and in vivo preclinical studies using lipid-based nanosystems. Readers can find up-to-date information on the most common experiments performed to predict the clinical behavior of lipid-based nanosystems. A series of 15 research articles and a review are presented, with authors from 15 different countries, which demonstrates the universality of the investigations that have been carried out in this area.

Abstract

In the search for a healthier diet and facing the uncertainties about the consumption of artificial additives, the scientific community has explored in the last years the potential of natural compounds, such as polyphenols, carotenoids, chlorophylls, essential oils, tocopherols, vitamins, polysaccharides, among others, obtained from the most diverse sources, such as plants and fungi, for the replacement of the artificial additives in food, which has made these compounds recognized as “natural additives”. In addition to being considered less harmful to health, and giving a certain functional property to a foodstuff, natural additives can also provide a beneficial synergistic effect in the food matrix. For the consumers, diverse studies have been showed that regular ingestion of bioactive compounds, that can be applied as natural additives, can be helpful for the prevention/treatment of several chronic and aging illnesses, such as cardiovascular diseases and neurological disorders. However, there is much to be researched on the viable use of bioactive compounds and to overcome their chemical limitations so that it can actually be used as natural additives in foods. This book addresses, through 18 scientific articles, some natural compounds with potential for use as preservatives, nutritional additives, coloring agents, flavorings, and various agents.

Abstract

The analysis of circulating tumor cells (CTCs) as a real-time liquid biopsy approach can be used to obtain new insights into metastasis biology, and as companion diagnostics to improve the stratification of therapies and to obtain insights into the therapy-induced selection of cancer cells. In this book, we will cover all the different facets of CTCs to assemble a huge corpus of knowledge on cancer dissemination: technologies for their enrichment, detection, and characterization; their analysis at the single-cell level; their journey as CTC microemboli; their clinical relevance; their biology with the epithelial-to-mesenchymal transition (EMT); their stem-cell properties; their potential to initiate metastasis at distant sites; their ex vivo expansion; and their escape from the immune system.

Abstract

Recently, microfluidic, nanofluidic and lab-on-a-chip devices have gained particular attention in biomedical applications. Due to their advantages, such as miniaturization, versatility, ease of use, cost-effectiveness, and the potential to replace animal models for drug development and testing, these devices hold tremendous potential to revolutionize the research of more effective treatments for several diseases that threaten human life. With integrated biosensors, these devices allow the development and design of micro- and nanoparticles to be studied in detail, modelling human physiology, investigating the molecular and cellular mechanisms underlying disease formation and progression, and gaining insights into the performance and long-term effects of responsive drug delivery nanocarriers. This Special Issue gathered research papers, and review articles focusing on novel microfluidic, nanofluidic and lab-on-a-chip devices for biomedical applications, addressing all steps related to fabrication, biosensor integration and development, characterization, numerical simulations and validation of the devices, optimization and, the translation of these devices from research labs to industry settings.
