Efficient isolation, characterization, and culture of endometrial epithelial cells and stromal fibroblasts from calf uteri collected at the slaughterhouse is key to develop useful 3D culture tissue models to investigate uterine physiology and pathology without the need of performing invasive procedures to recover tissue samples.Here we provide a detail methodology that gives consistently pure and viable populations of distinct primary bovine endometrial cells.Cells have a remarkable ability to self-organize and rearrange in functional organoids, this process was greatly boosted by the recent advances in 3D culture technologies and materials. Presently, this approach can be applied to model human organ development and function "in a dish" and can be used to predict drug response in a patient specific fashion.Here we describe a protocol that allows for the derivation of functional cardiac mini organoids consisting of cocultured cardiomyocytes and cardiac fibroblast. Cells are suspended in a drop of medium and encapsulated with hydrophobic fumed silica powder nanoparticles. These nanoparticles are treated with hydrophobic chemicals, hexamethyldisilazane (nHMDS), and result in the formation of microbioreactors. These microenvironments are defined as "liquid marbles," stimulating cell coalescence and 3D aggregation. Phenazine methosulfate price Then nHMDS shell ensures optimal gas exchange between the interior liquid and the surrounding environment. This microbioreactor makes working in smaller volumes possible and is therefore amenable for higher throughput applications. Moreover, the properties of liquid marble microbioreactors makes it an excellent culture technique for cocultures. Here we demonstrate how cocultures of cardiac fibroblast and cardiomyocytes in a cardiosphere can be a valuable tool to model cardiac diseases in vitro and to assess cell interactions to decipher disease mechanisms.The technological revolution in reproductive biology that started with artificial insemination procedures and embryo transfer led to the development of assisted reproduction techniques such as in vitro fertilization or even cloning of domestic animals by nuclear transfer from somatic cells. Currently, procedures of isolated immature ovarian follicles in vitro culture are becoming the prominent technology aimed to preserve or restore fertility especially of young oncological patients or those at risk of premature ovarian failure.Here, we describe a protocol that can be applied for in vitro growth of porcine, preantral ovarian follicles in three-dimensional (3D) culture conditions. After enzymatic isolation from the ovarian cortex, preantral follicles are suspended in a drop of medium and enclosed with fluorinated ethylene propylene (FEP) powder particles (microbioreactors). Such microbioreactors maintain the 3D structure of the follicles during the whole process of in vitro growth what is crucial to ensure proper folliculogenesis progression and their ability to survive.Extracellular vesicles (EVs) are vesicles released by cells, which due to their cargo and cell membrane proteins induce changes in the recipient cells. link2 These vesicles can be a novel option to induce stem cell differentiation. Here we described a method to induce mesenchymal stem cell differentiation (MSC) into neuron-like cells using small EVs from neurons. First, we will describe a method based on neurons to induce adipocyte derived stem cells differentiation, a type of MSC, by coculturing both using inserts. Secondly, we will describe a follow-up method by using only isolated neuron-derived small EVs to directly induce ADSC differentiation in neuron-like cells. Importantly, in both methods it is possible to avoid the direct cell-to-cell contact, thus allowing for the study of soluble factors role during stem cell differentiation.Growing cells as 3D structures need not be difficult. Often, it is not necessary to change cell type, additives or growth media used. All that needs to be changed is the geometry cells (whether primary, induced pluripotent, transformed or immortal) simply have to be grown in conditions that promote cell-cell adhesion while allowing gas, nutrient, signal, and metabolite exchange. Downstream analysis can become more complicated because many assays (like phase contrast microscopy) cannot be used, but their replacements have been in use for many years. Most importantly, there is a huge gain in value in obtaining data that is more representative of the organism in vivo. It is the goal of the protocols presented here to make the transition to a new dimension as painless as possible. Grown optimally, most biopsy derived organoids will retain patient phenotypes, while cell (both stem cell, induced or otherwise or immortalized) derived organoids or spheroids will recover tissue functionality.The mammalian ovary is a large source of oocytes organized into follicles at various stages of folliculogenesis. However, only a limited number of them can be used for in vitro embryo production (IVEP), while most have yet to complete growth and development to attain full meiotic and embryonic developmental competence. While the in vitro growth of primordial follicles in the ovarian cortex has the potential to produce mature oocytes, it is still at an experimental stage. The population of early antral follicles (EAFs), instead, may represent a reserve of oocytes close to completing the growth phase, which might be more easily exploited in vitro and could increase the number of female gametes dedicated to IVEP.Here we present in vitro culture strategies that have been developed utilizing physiological parameters to support the specific needs of oocytes at distinct stages of differentiation, in order to expand the source of female gametes for IVEP by maximizing the attainment of fertilizable oocytes. Furthermore, these culture systems provide powerful tools to dissect the molecular processes that direct the final differentiation of the mammalian oocyte.
Previous studies have indicated that right ventricular (RV) function is damaged in diabetes mellitus (DM); however, it is not clear whether in the presence of chronic ischemia, RV function is different between patients with and without DM (DM + and DM - , respectively).

This cross-sectional study enrolled 90 consecutive candidates for coronary artery bypass graft surgery and allocated them to 3 groups 24 DM - patients with the absence of stenosis of more than 50% in the proximal and mid parts of the right coronary artery (the DM - RCA - group [control]), 33 DM - patients with the presence of significant stenosis (> 70%) in the proximal part of RCA (the DM - RCA + group), and 33 DM + patients with RCA + (the DM + RCA + group). RV function was evaluated based on longitudinal deformation markers, measured via the 2D speckle-tracking echocardiographic examination of right ventricular free wall (RVFW).

The systolic strain value, systolic strain rate, and late diastolic strain rate of RVFW were not statistically significantly different between the three groups. Our adjusted post hoc analysis showed that the early diastolic strain rate of RVFW in the DM + RCA + group was lower than that in the DM - RCA + and DM - RCA - groups (1.5s
 ± 0.4 vs 1.7s
 ± 0.5 vs 1.7s
 ± 0.4).

Diastolic function in the presence of DM was impaired irrespective of RCA - or RCA + . Additionally, RCA + had no effect on systolic and diastolic RV functions at rest in our DM - patients.

Many patients with chronic pulmonary diseases, such as interstitial lung disease, cystic fibrosis, and non-cystic fibrosis bronchiectasis, suffer from dyspnea and exercise intolerance. Reduced lung compliance is the main cause of the patients' dyspnea, but weak respiratory muscles could be an additional factor. The diaphragm is considered the major respiratory muscle. Our study aimed to detect diaphragmatic thickness and excursion by ultrasound in pediatric patients with chronic pulmonary diseases to assess respiratory muscle weakness in these patients.

A case-control study was conducted on 130 patients with pediatric chronic pulmonary diseases (childhood interstitial lung diseases, cystic fibrosis, and non-cystic fibrosis bronchiectasis) and 100 control subjects. Ultrasound was used to detect diaphragmatic excursion and thickness, which were correlated with the severity of the disease, both clinically and functionally.

The right and left diaphragmatic excursions were significantly lower in the patientsage, weight, height, FEV1/FVC ratio, and heart rate.Although there have been major strides toward uncovering the neurobehavioral mechanisms involved in cognitive functions like memory and decision making, methods for measuring behavior and accessing latent processes through computational means remain limited. To this end, we have created SUPREME (Sensing to Understanding and Prediction Realized via an Experiment and Modeling Ecosystem) a toolbox for comprehensive cognitive assessment, provided by a combination of construct-targeted tasks and corresponding computational models. SUPREME includes four tasks, each developed symbiotically with a mechanistic model, which together provide quantified assessments of perception, cognitive control, declarative memory, reward valuation, and frustrative nonreward. In this study, we provide validation analyses for each task using two sessions of data from a cohort of cognitively normal participants (N = 65). Measures of test-retest reliability (r 0.58-0.75), stability of individual differences (ρ 0.56-0.70), and internal consistency (α 0.80-0.86) support the validity of our tasks. After fitting the models to data from individual subjects, we demonstrate each model's ability to capture observed patterns of behavioral results across task conditions. Our computational approaches allow us to decompose behavior into cognitively interpretable subprocesses, which we can compare both within and between participants. We discuss potential future applications of SUPREME, including clinical assessments, longitudinal tracking of cognitive functions, and insight into compensatory mechanisms.Biotherapeutics are highly efficacious, but the pain and inconvenience of chronic injections lead to poor patient compliance and compromise effective disease management. Despite innumerable attempts, oral delivery of biotherapeutics remains unsuccessful due to their degradation in the gastrointestinal (GI) environment and poor intestinal absorption. link3 We have developed an orally ingestible robotic pill (RP) for drug delivery, which protects the biotherapeutic drug payload from digestion in the GI tract and auto-injects it into the wall of the small intestine as a safe, pain-free injection since the intestines are insensate to sharp stimuli. The payload is delivered upon inflation of a balloon folded within the RP, which deflates immediately after drug delivery. Here we present results from two clinical studies demonstrating the safety, tolerability and performance of the RP in healthy humans. In the first study, three versions of the RP (A, B and C) were evaluated, which were identical in all respects except for the diameter of the balloon.
