Larger Stabilizing Particles Make Stronger Liquid Marble.

Small 2018 Dec 13:e1804549. Epub 2018 Dec 13.

Department of Biomedical Engineering, School of Medicine, Shenzhen University, Shenzhen, Guangdong, 518060, China.

Understanding the mechanical stability of granular-armored liquid marbles is prerequisite for their applications including encapsulation, sensors, microreactions, and miniaturized liquid storage. Most liquid marbles are armored with agglomerated granular structure which complicates the wetting and interacting states of particles, hence, impeding one from understanding the effect of granular size on the mechanical stability of marbles. In this work, using a custom-built platform to examine the liquid marbles armored by a single layer of uniform grains, it is revealed that larger microsized grains produce stronger liquid marble.

Integrated internal standards: A sample prep-free method for better precision in microchip CE.

Electrophoresis 2018 Dec 13. Epub 2018 Dec 13.

BIOS-Lab on a Chip Group, MESA+ Institute of Nanotechnology, TechMed Centre and Max Planck Center for Complex Fluid Dynamics, University of Twente, Enschede, Overijssel, The Netherlands.

Point-of-care systems based on microchip capillary electrophoresis require single-use, disposable microchips pre-filled with all necessary solutions so an untrained operator only needs to apply the sample and perform the analysis. While microchip fabrication can be (and has been) standardized, some manufacturing differences between microchips are unavoidable. To improve analyte precision without increasing device costs or introducing additional error sources, we recently proposed the use of integrated internal standards (ISTDs): ions added to the BGE in small concentrations which form system peaks in the electropherogram that can be used as a measurement reference.

Bone marrow endothelial cells sustain a tumor-specific CD8 T cell subset with suppressive function in myeloma patients.

Oncoimmunology 2019 22;8(1):e1486949. Epub 2018 Oct 22.

Department of Biomedical Sciences and Human Oncology, Unit of Internal Medicine "Guido Baccelli", University of Bari Medical School, Bari, Italy.

Endothelial cells (EC) line the bone marrow microvasculature and are in close contact with CD8 T cells that come and go across the permeable capillaries. Because of these intimate interactions, we investigated the capacity of EC to act as antigen-presenting cells (APC) and modulate CD8 T cell activation and proliferation in bone marrow of patients with multiple myeloma (MM) and monoclonal gammopathy of undetermined significance. We found that EC from MM patients show a phenotype of semi-professional APC given that they express low levels of the co-stimulatory molecules CD40, CD80 and CD86, and of the inducible co-stimulator ligand (ICOSL).

Neutrophil Mechanosignaling Promotes Integrin Engagement With Endothelial Cells and Motility Within Inflamed Vessels.

Front Immunol 2018 28;9:2774. Epub 2018 Nov 28.

Simon Lab, Department of Biomedical Engineering, University of California, Davis, Davis, CA, United States.

Neutrophils are the most motile of mammalian cells, a feature that enables them to protect the host against the rapid spread of pathogens from tissue into the circulatory system. A critical process is the recruitment of neutrophils to inflamed endothelium within post-capillary venules. This occurs through cooperation between at least four families of adhesion molecules and G-protein coupled signaling receptors. Read More

Pathology and pathobiology of pulmonary hypertension: state of the art and research perspectives.

Eur Respir J 2018 Dec 13. Epub 2018 Dec 13.

Cardiovascular Institute, Dept of Pediatrics, Stanford University School of Medicine, Stanford, CA, USA.

Clinical and translational research has played a major role in advancing our understanding of pulmonary hypertension (PH), including pulmonary arterial hypertension and other forms of PH with severe vascular remodelling ( chronic thromboembolic PH and pulmonary veno-occlusive disease). However, PH remains an incurable condition with a high mortality rate, underscoring the need for a better transfer of novel scientific knowledge into healthcare interventions. Herein, we review recent findings in pathology (with the questioning of the strict morphological categorisation of various forms of PH into pre- or post-capillary involvement of pulmonary vessels) and cellular mechanisms contributing to the onset and progression of pulmonary vascular remodelling associated with various forms of PH.

Pore-scale fluid processes in geological media are critical for numerous applications in several fields. Continued improvement of high-resolution image acquisition and processing methods has provided a means to directly characterize pore-scale fluid processes for natural geomedia, and to test the representativeness of theoretical and computational models developed to simulate them. High-resolution synchrotron X-ray microtomography (XMT) combined with advanced 3-D image visualization was used to investigate the impact of larger-scale solid-surface heterogeneity on nonwetting-wetting (air-water) interfacial area for two natural geomedia (a sand and a soil).

Dual cationic-anionic profiling of metabolites in a single identified cell in a live Xenopus laevis embryo by microprobe CE-ESI-MS.

Analyst 2018 Dec 13. Epub 2018 Dec 13.

Department of Chemistry & Biochemistry, University of Maryland, College Park, MD 20742, USA.

In situ capillary microsampling with capillary electrophoresis (CE) electrospray ionization (ESI) mass spectrometry (MS) enabled the characterization of cationic metabolites in single cells in complex tissues and organisms. For deeper coverage of the metabolome and metabolic networks, analytical approaches are needed that provide complementary detection for anionic metabolites, ideally using the same instrumentation. Described here is one such approach that enables sequential cationic and anionic (dual) analysis of metabolites in the same identified cell in a live vertebrate embryo. Read More

Objective: To investigate the regulative effect of hemichannels protein Pannexin-1 on P2X7 receptor activation and caspase-1 mediated inflammatory response in the lungs of mice with lung injury.

Methods: Sixty male C57BL/6 mice were randomly divided into five groups with 12 mice in each group: sham operation group (Sham group), mechanical ventilation (MV) group, MV + low dose lipopolysaccharide (LPS) group (MLL group), MV + medium and high dose LPS group (MML group) and MV + high dose LPS group (MHL group). A "two-hit" lung injury model was reproduced by MV with high tidal volume combined with LPS injection in airway. Read More

Anti-PD1 'SHR-1210' aberrantly targets pro-angiogenic receptors and this polyspecificity can be ablated by paratope refinement.

MAbs 2018 Dec 12:1-19. Epub 2018 Dec 12.

a UltraHuman Limited, Codebase , Edinburgh , UK.

Monoclonal anti-programmed cell death 1 (PD1) antibodies are successful cancer therapeutics, but it is not well understood why individual antibodies should have idiosyncratic side-effects. As the humanized antibody SHR-1210 causes capillary hemangioma in patients, a unique toxicity amongst anti-PD1 antibodies, we performed human receptor proteome screening to identify nonspecific interactions that might drive angiogenesis. This screen identified that SHR-1210 mediated aberrant, but highly selective, low affinity binding to human receptors such as vascular endothelial growth factor receptor 2 (VEGFR2), frizzled class receptor 5 and UL16 binding protein 2 (ULBP2).

Bone marrow-derived mesenchymal stem cells attenuate tubulointerstitial injury through multiple mechanisms in UUO model.

J Cell Biochem 2018 Dec 7. Epub 2018 Dec 7.

Department of Biochemistry and Molecular Biology, Harbin Medical University, Harbin, Heilongjiang, China.

Current evidence supports the use of bone marrow-derived mesenchymal stem cells (MSCs) for a diverse range of clinical applications, and many studies have shown that MSCs have renal-protective effects, but the mechanism is not well understood. Therefore, in this study, we aim to further identify whether MSCs can attenuate renal fibrosis by decreasing tubulointerstitial injury in a unilateral ureteral obstruction (UUO) model. In this study, we cultured MSCs and then transplanted them into a UUO model through the tail vein. Read More

Pretreatment with an angiotensin II receptor blocker abolished ameliorating actions of adipose-derived stem cell sheets on cardiac dysfunction and remodeling after myocardial infarction.

Regen Ther 2018 Dec 19;9:79-88. Epub 2018 Sep 19.

Division of Regenerative Medicine and Therapeutics, Department of Genetic Medicine and Regenerative Therapeutics, Tottori University Graduate School of Medical Science, 86 Nishi-cho, Yonago 683-8503, Japan.

Introduction: Cell sheets using myoblasts have been developed for the treatment of heart failure after myocardial infarction (MI) bridging to heart transplantation. Stem cells are supposed to be better than myoblasts as a source of cells, since they possess a potential to proliferate and differentiate into cardiomyocytes, and also have capacity to secrete angiogenic factors. Adipose-derived stem cells (ASCs) obtained from fat tissues are expected to be a new cell source for ASC sheet therapies. Read More

Comparison of the efficacy of cryopreserved human platelet lysate and refrigerated lyophilized human platelet lysate for wound healing.

Regen Ther 2019 Jun 20;10:1-9. Epub 2018 Nov 20.

Department of Plastic and Reconstructive Surgery, Kansai Medical University, 2-5-1 Shin-machi, Hirakata City, Osaka, 573-1010, Japan.

Introduction: Human platelet lysate (hPL) part of the growth factor cocktail derived from human platelets, which has been applied as a cell growth supplement. The production process is easier in comparison to platelet-rich plasma; thus, hPL is now considered for use in wound healing therapy. However, methods for preserving hPL for more than several months that maintain its bioactivity must be considered, especially for chronic wound treatment. Read More
