This study didn't measure whether receiving the cardiosphere-derived cells extended lifespans, so we have a lot more work to do. We have much to study, including whether CDCs need to come from a young donor to have the same rejuvenating effects and whether the extracellular vesicles are able to reproduce all the rejuvenating effects we detect with CDCs." Cardiac and systemic rejuvenation after cardiosphere-derived cell therapy in senescent rats Cardiosphere-derived cell (CDC) therapy has exhibited several favourable effects on heart structure and function in humans and in preclinical models; however, the effects of CDCs on aging have not been evaluated. We compared intra-cardiac injections of neonatal rat CDCs to a control of phosphate-buffered saline, PBS, in 21.8 ± 1.6 month-old rats (mean ± standard deviation; n = 23 total). Ten rats of 4.1 ± 1.5 months of age comprised a young reference group. Blood, echocardiographic, haemodynamic and treadmill stress tests were performed at baseline in all animals, and 1 month after treatment in old animals. Histology and the transcriptome were assessed after terminal phenotyping. For in vitro studies, human heart progenitor cells from older donors, or cardiomyocytes from aged rats were exposed to human CDCs or exosomes secreted by CDCs from paediatric donors. Transcriptomic analysis revealed that CDCs, but not...

Authors: Fournier E Abstract Carpal tunnel syndrome (CTS) is too common a condition not to daily interact with the practitioner, if only because of its entanglement to other pathologies, causal or chance association. The typical symptomatology, with hand paresthesia and morning pain upon waking, is related to a median nerve injury in the confined space of the carpal tunnel, more often by local inflammation and tenosynovitis of the finger flexors (repetitive activity of the hands). SCC may be secondary to situations (pregnancy) or conditions (edema, hypothyroidism…), which exaggerate the ordinary pathophysiol...

In this study, 2-urea-chitosan oligosaccharide derivatives (2-urea-COS derivatives) and 2,6-diurea-chitosan oligosaccharide derivatives (2,6-diurea-COS derivatives) were successfully designed and synthesized via intermediate 2-methoxyformylated chitosan oligosaccharide. All samples were characterized and compared based on FT-IR, 1H NMR spectroscopy, and elemental analysis. The antifungal effects of COS derivatives were tested against Fusarium oxysporum f. sp. niveum, Phomopsis asparagus, and Botrytis cinereal. Their antioxidant properties, including superoxide radicals’ scavenging activity, hydroxyl radicals’ s...

Publication date: April 2020Source: Colloids and Surfaces B: Biointerfaces, Volume 188Author(s): Didem Cetin, Meltem Okan, Erhan Bat, Haluk KulahAbstractDetection of circulating tumor cells (CTCs) from the bloodstream holds great importance to diagnose cancer at early stages. However, CTCs being extremely rare in blood makes them difficult to reach. In this paper, we introduced different surface modification techniques for the enrichment and detection of MCF-7 in microfluidic biosensor applications using gold surface and EpCAM antibody. Mainly, two different mechanisms were employed to immobilize the antibodies; covalent b...

The as-prepared ZnO nanoparticles had the hexagonal wurtzite structure with maximum absorption at 355 nm and the band gap energy was found to be 3.21 eV. The electron microscopy analysis showed that the ZnO nanoparticles are spherical in shape with an average size range...

Municipal effluents, which are complex mixtures of biological and chemical compounds including flame retardants, have been shown to alter lipid metabletabolism in environmentally and experimentally exposed fish. Down-regulation of several genes coding for fatty acid metabolism enzymes has previously been reported in male northern pike (Esox lucius) collected in the St. Lawrence River (Q...

CONCLUSIONS: Formulations containing antioxidant vitamins, R-alpha lipoic acid and docosahexaenoic acid, administered for 6 consecutive months, counteracted the oxidative stress by further stabilising the morphological/functional parameters of both the ocular surface and the glaucoma, without presenting with adverse effects or intolerances.
