We report on the formation by mechanical alloying of fcc solid solution Fe and Cu, which are immiscible. Intense codeformation Cu with other high-melting bcc metals generates small fragments tip radii order 1 nm such that capillary pressures force atoms these to dissolve. The critical radius for dissolution is found increase solute content inside spinodal thus leading full one components. fcc-FeCu solutions have Curie temperatures similar those vapor-deposited alloys a positive heat mixing...
Cell-to-cell communication is essential for the appropriate development and maintenance of homeostatic conditions in central nervous system. Extracellular vesicles have recently come to forefront neuroscience as novel vehicles transfer complex signals between neuronal cells. are membrane-bound carriers packed with proteins, metabolites, nucleic acids (including DNA, mRNA, microRNAs) that contain elements present cell they originate from. Since their discovery, extracellular been studied...
Dietary supplements enriched with bioactive compounds represent a promising approach to influence physiological processes and enhance longevity overall health. Cynara cardunculus var. scolymus serves as functional food supplement high concentration of compounds, which offers various health-promoting benefits. Several chronic diseases have metabolic, genetic, or inflammatory origins, are frequently interconnected. Pharmacological treatments, although effective, often result in undesirable...
Microparticles (MPs) are small fragments generated from the plasma membrane after cell stimulation or apoptosis. We have recently shown that MPs harboring morphogen Sonic Hedgehog (MPs Shh+ ) correct endothelial injury by release of nitric oxide cells [Agouni, Mostefai, Porro, Carusio, Favre, Richard, Henrion, Martínez and Andriantsitohaina (2007) FASEB J., 21, 2735–2741]. Here, we show induce formation capillary-like structures in an vitro model using human cells, although they inhibited...
Microparticles (MPs) are vesicles released from plasma membrane upon cell activation and during apoptosis. Human T lymphocytes undergoing apoptosis generate MPs bearing morphogen Shh (MPs(Shh+)) that able to regulate in vitro angiogenesis.Here, we investigated the ability of MPs(Shh+) modulate neovascularization a model mouse hind limb ischemia. Mice were treated vivo for 21 days with vehicle, MPs(Shh+), plus cyclopamine or alone, an inhibitor signalling. Laser doppler analysis revealed...
Vitamin D plays an essential role in maintaining bone density, building the immune system, and regulating cell growth alongside other key biological functions. Limited data are available about seasonal variation vitamin levels pediatric population Saudi Arabia. This study aimed to investigate influence on circulating of 25(OH)D. A total 1790 outpatients who visited University healthcare centre were included this study. Overall, there was a noticeably high prevalence (69%) both combined...
Microparticles are membrane vesicles with pro-inflammatory properties. Circulating levels of microparticles have previously been found to be elevated in patients metabolic syndrome (MetS). The present study aimed evaluate the effects vivo treatment microparticles, from MetS and healthy subjects (HS), on ex vascular function mice. isolated or HS, a vehicle were intravenously injected into mice, following which reactivity response vasoconstrictor agonists was assessed by myography respect...
Background Bone marrow-derived endothelial progenitor cells (EPCs) are critical for neovascularization. We hypothesized that microparticles (MPs), small fragments generated from the plasma membrane, can activate angiogenic programming of EPCs. Methodology/Principal Findings studied effects MPs obtained wild type (MPsPPARα+/+) and knock-out (MPsPPARα−/−) mice on EPC differentiation angiogenesis. were isolated WT or KO cultured in presence MPsPPARα+/+ MPsPPARα−/− blood mice. Only harboring...
