The available gel types are suitable for mimicking a variety of tissue types, including cardiac tissue and blood vessels.

Custom, tissue-mimicking flow phantoms can be fabricated using the developed methodology and have potential for use in a variety of applications, including ultrasound-based imaging methods. This is the first reported use of BSI with an in vitro flow phantom.

The aim of this study was to establish reference intervals for RBC parameters and platelet count for healthy adults in Japan. A total of 750 healthy adults (447 women and 303 men; median age 40 years (18-67 years) at seven Japanese centers who participated in regular medical checkups entered this study. Their RBC parameters and platelet count were measured using automated hematocytometers. The reference intervals of the RBC parameters and platelet count according to sex in healthy adults were determined. There was an age-specific decrease in RBC counts and an age-specific increase in mean corpuscular volume in men. This study emphasizes the need to consider sex and age in the clinical use of reference intervals of RBC parameters.Conventional transmission electron microscopy is an essential tool to understand the structure-function relationships and play a vital role in biological research. Mitochondria-associated membranes are linked with cancer processes in a fundamental manner. A conventional transmission electron microscopy method for preparing specimens in clinical and research settings for the study-analysis of the mitochondria-associated membranes in human tumors is presented. The sample processing includes chemical fixation by immersion, dehydration, embedding, polymerization, sectioning, and staining.In recent years, next-generation sequencing (NGS) has become a powerful tool for studying both inherited and somatic heteroplasmic mitochondrial DNA (mtDNA) variation. NGS has proved particularly powerful when combined with single-cell isolation techniques, allowing the investigation of low-level heteroplasmic variants both between cells and within tissues. Nevertheless, there remain significant challenges, especially around the selective enrichment of mtDNA from total cellular DNA and the avoidance of nuclear pseudogenes. This chapter summarizes the techniques needed to enrich, amplify, sequence, and analyse mtDNA using NGS .Intracellular Ca2+ is strictly regulated to maintain optimal levels for function of cellular organelles as well as mitochondrial respiratory signaling at the tricarboxylic acid cycle and electron transport chain level. Optimal Ca2+ concentration for these processes vary between cell types. Furthermore, exposure of mitochondria to sustained, elevated levels of Ca2+ induces mitochondrial Ca2+ overload and damage to mitochondrial oxidative phosphorylation and ATP production. Isolated mitochondria are widely used to study mitochondrial physiology and drug effects on mitochondrial metabolism and respiratory function. However, isolated mitochondria are easily damaged during the mitochondrial isolation process. The present article describes a mitochondrial isolation method using Ca2+-chelation to minimize mitochondrial damage. We follow up the isolation process with an application that requires an optimized buffer Ca2+ concentration the characterization of their respiratory function using a high-resolution respirometric assay.The more recent studies of human pathologies have essentially revealed the complexity of the interactions involved at the different levels of integration in organ physiology. Integrated organ thus reveals functional properties not predictable by underlying molecular events. It is therefore obvious that current fine molecular analyses of pathologies should be fruitfully combined with integrative approaches of whole organ function. It follows that an important issue in the comprehension of the link between molecular events in pathologies and whole organ function/dysfunction is the development of new experimental strategies aimed at the study of the integrated organ physiology. Cardiovascular diseases are a good example as heart submitted to ischemic conditions has to cope both with a decreased supply of nutrients and oxygen, and the necessary increased activity required to sustain whole body-including the heart itself-oxygenation.By combining the principles of control analysis with noninvasive 31P NMR measureme heart that evidence different modes of energetic regulation of cardiac contraction. We also discuss the clinical application by using noninvasive 31P cardiac energetics examination under clinical conditions for detection of heart pathologies.Cellular metabolism contributes to cell fate decisions. Bioenergetic profiling can therefore provide considerable insights into cellular identity and specification. Given the current importance of human pluripotent stem cells (hPSCs) for biomedical applications, assessing the bioenergetic properties of hPSCs and derivatives can unveil relevant mechanisms in the context of development biology and molecular disease modeling. Here, we describe a method to facilitate bioenergetic profiling of hPSCs in a reproducible and scalable manner. After simultaneous assessment of mitochondrial respiration and glycolytic capacity using Seahorse XFe96 Analyzer, we measure lactate concentration in the cellular media. Finally, we normalize the values based on DNA amount. We describe the procedures with specific requirements related to hPSCs . WZ811 molecular weight However, the same protocol can be easily adapted to other cell types, including differentiated progenies from hPSCs .In vitro experiments using permeabilized cells and/or isolated mitochondria represent a powerful biochemical tool for elucidating the role of the mitochondrion in driving disease. Such analyses have routinely been utilized across multiple scientific fields to shed valuable insight on mitochondrial-linked pathologies. The present chapter is intended to serve as a methodological blueprint for comprehensively phenotyping peripheral blood cell mitochondria. While primarily adapted for peripheral blood cells, the protocols outlined herein could easily be made amenable to most all cell types with minimal modifications.
