Parameter estimation: an advanced simulation tool in biomedicine

1990

Parameter estimation as an advanced tool in biomedicine have become extremely important in the study of biological systems. With increasing physiological knowledge and more efficient computers, modelling, simulation, and estimation have grown during the past 20 years to one of the most powerful tools of biomedical system analysis. Moreover modelling, simulation and estimation is of growing importance for determination of non-measurable parameters and state variables of biomedical systems as well as for case studies research of biomedical processes, which have been developed by physicians and system engineers and have also been widely accepted by biomedical scientists. These models already d…

An evidence based therapeutic approach to hereditary and acquired angioedema

2014

Purpose of review Hereditary angioedema (HAE) due to C1 esterase inhibitor (C1-INH) deficiency (HAE-C1-INH), HAE with normal C1-INH, and acquired angioedema due to C1-INH deficiency are rare but important diseases that can be associated with significant morbidity and mortality. Research into the pathogenesis of angioedema has expanded greatly and has led to new clinical trials with novel therapeutic agents and strategies. Recent findings Strategies for managing HAE-C1-INH are aimed at treating acute attacks or preventing attacks through the use of prophylactic treatment. Agents available in Europe for treating acute attacks include plasma-derived C1-INH concentrates, a bradykinin B2 recepto…

Biochemical composition of muscle extracellular matrix: the effect of loading

2000

Collagen plays an important role in skeletal muscle both during muscle differentiation and normal muscle growth, and also serves a role as a supportive structure. It is the most abundant protein of the extracellular matrix and of the 19 distinct collagen types, types I, III, IV and V are the dominating ones in skeletal muscle. Both collagen synthesis as well as degradation is influenced by either physical loading or immobilization in skeletal muscle, and recent methods have allowed for greater understanding of the posttranslational processing of collagen.

Learning how to live together: genomic insights into prokaryote–animal symbioses

2008

Our understanding of prokaryote-eukaryote symbioses as a source of evolutionary innovation has been rapidly increased by the advent of genomics, which has made possible the biological study of uncultivable endosymbionts. Genomics is allowing the dissection of the evolutionary process that starts with host invasion then progresses from facultative to obligate symbiosis and ends with replacement by, or coexistence with, new symbionts. Moreover, genomics has provided important clues on the mechanisms driving the genome-reduction process, the functions that are retained by the endosymbionts, the role of the host, and the factors that might determine whether the association will become parasitic…

An overview of nanoparticles role in the improvement of barrier properties of bioplastics for food packaging applications

2017

Abstract Plastics are the most demanding materials for the food packaging industry due to economical and practical reasons such as their low cost, lightness, easy to handle in integrated production lines, and their higher resistance than other materials. Besides containment and information, the packaging should protect foodstuffs from not only contamination but also the loss of food quality. Despite the many advantages, their inherent permeability is perhaps the foremost drawback that could lead to the loss of some food components and, also, to the transference of gases or moisture from the surrounding to the food. Thus, the barrier properties and the wettability are of fundamental importan…

Nonthermally driven volatilome evolution of food matrices: The case of high pressure processing

2020

Abstract Background The adoption of innovative nonthermal processing as alternatives to conventional heating techniques in the food industry is mainly relied on their tremendous potential to simultaneously achieve preservation purposes and the maintenance of fresh-like characteristics and health benefits of final products. With increasing evaluation for the applicability of nonthermal processing, there remains, however, a great challenge for keeping the balance between the efficiency of microbial/enzymatic inactivation and the maintenance of sensory and nutritional characteristics. Accordingly, a timely summarization and elucidation of the response pattern and mechanism of related quality p…

An overview of the potential applications based on HPP mechanism

2020

Abstract Over the last decades, high-pressure processing (HPP) has shown its potential as one of the most relevant technologies for nonthermal food processing mainly due to its application for microbial inactivation while retaining fresh-like characteristics of the food. Moreover, HPP can be considered as a potential tool for developing new food products with new sensorial and functional properties. Apart from food preservation, the application of HPP to improve health attributes (e.g., reducing food contaminants or salt concentration), and to enhance the extraction or fermentation processes, has been an interesting research topic around the world. This chapter intends to show the core-base…

Green technologies for food processing: Principal considerations

2019

Abstract The environmental impact of the food industry is of increasing concern for our society. Reductions in the amounts of harmful substances produced and in energy consumption, and increases in by-product recycling, are all requirements that the industry must now meet. However, “green technology” concepts are currently driving the development of new techniques in this field. Emerging green technologies are capable of superseding conventional thermal treatment, which negatively affects the physical, nutritional, and bioactive properties of food, and are also more environmentally friendly. Novel green techniques include ionizing and ultraviolet radiation, ohmic heating, high-power ultraso…

The potential of pulsed electric fields to reduce pesticides and toxins

2020

Abstract Several studies have demonstrated the feasibility of pulsed electric fields (PEF) for different applications in the food industry. PEF technology is a valuable tool to improve functionality, extractability, and recovery of nutritionally valuable compounds as well as bioavailability of micronutrients and components in a diverse variety of foods. Moreover, some studies have shown the potential of PEF treatments to reduce the formation of food processing contaminants, pesticides, and toxins. This opens the doors to new PEF applications in the food industry. Recently, scientists explored the possibility of removing harmful chemical, such as pesticides and toxins, from food commodity by…
