BACKGROUND: Nintedanib is an inhibitor targeting platelet-derived growth factor receptor, fibroblast growth factor receptor and vascular endothelial growth factor receptor tyrosine kinases that has recently been approved for the treatment of idiopathic pulmonary fibrosis. The aim of this study was to analyse the effects of nintedanib in the fos-related antigen-2 (Fra2) mouse model of systemic sclerosis (SSc). METHODS: The effects of nintedanib on pulmonary arterial hypertension with proliferation of pulmonary vascular smooth muscle cells (PVSMCs) and luminal occlusion, on microvascular disease with apoptosis of microvascular endothelial cells (MVECs) and on fibroblast activation with myofibroblast differentiation and accumulation of extracellular matrix were analysed...

In this paper we present the design of a one degree of freedom assistive platform to augment the strength of upper limbs. The core element is a variable stiffness actuator, closely reproducing the behavior of a pair of antagonistic muscles. The novelty introduced by this device is the analogy of its control parameters with those of the human muscle system, the threshold lengths. The analogy can be obtained from a proper tuning of the mechanical system parameters. Based on this, the idea is to control inputs by directly mapping the estimation of the muscle activations, e...

The almost complete loss of the membrane cytoskeletal protein dystrophin and concomitant drastic reduction in dystrophin-associated glycoproteins are the underlying mechanisms of the highly progressive neuromuscular disorder Duchenne muscular dystrophy. In order to identify new potential binding partners of dystrophin or proteins in close proximity to the sarcolemmal dystrophin complex, proteomic profiling of the isolated dystrophin-glycoprotein complex was carried out. Subcellular membrane fractionation and detergent solubilisation, in combination with ion exchange, lectin chromatography and density gradient ultracentrifugation, was performed to isolate a dystrophin complex-enriched fraction...

Normal homeostatic functions of adult stem cells have rhythmic daily oscillations that are believed to become arrhythmic during aging. Unexpectedly, we find that aged mice remain behaviorally circadian and that their epidermal and muscle stem cells retain a robustly rhythmic core circadian machinery. However, the oscillating transcriptome is extensively reprogrammed in aged stem cells, switching from genes involved in homeostasis to those involved in tissue-specific stresses, such as DNA damage or inefficient autophagy...

BACKGROUND: Since neointima smooth muscle cells (SMC) mainly originate from the vessel wall, we investigated whether atherosclerotic plaque composition influences subsequent in-stent neointima proliferation and restenosis. METHODS: We performed intravascular ultrasound (IVUS) with virtual histology in 98 patients prior to elective bare-metal stent (BMS) implantation in de novo coronary artery lesions. Virtual histology variables pre-percutaneous coronary intervention (PCI) were related to in-stent neointima proliferation six months after implantation assessed as late luminal loss of 0...

Invadopodia are ventral membrane protrusions formed by cancer cells that degrade the extracellular matrix (ECM) during tumor invasion and metastasis. Formation of invadopodia is initiated by the assembly of actin filaments (F-actin) that results from the coordinated activation of several actin regulatory proteins. Actinin-1 and actinin-4 are actin bundling proteins expressed in non-muscle cells and actinin-4 is preferentially associated with malignant phenotypes of carcinoma cells. In this study, we investigated the role of actinin-1 and -4 in invadopodia formation...

BACKGROUND: [6]-Gingerol, a major component of Zingiber officinale, was previously reported to ameliorate hyperglycemia in type 2 diabetic mice. Endocrine signaling is involved in insulin secretion and is perturbed in db/db Type-2 diabetic mice. [6]-Gingerol was reported to restore the disrupted endocrine signaling in rodents. In this current study on Lepr(db/db) diabetic mice, we investigated the involvement of endocrine pathway in the insulin secretagogue activity of [6]-Gingerol and the mechanism(s) through which [6]-Gingerol ameliorates hyperglycemia...

The large amount of energy expended during flapping flight is associated with heat generated through the increased work of the flight muscles. This increased muscle work rate can manifest itself in core body temperature (Tb) increase of 1-2°C in birds during flight. Therefore, episodic body cooling may be mandatory in migratory birds. To elucidate the thermoregulatory strategy of a short-distance migrant, common eiders (Somateria mollissima), we implanted data loggers in the body cavity of wild birds for 1 year, and report information on Tb during their entire migration for 19 individuals...

BACKGROUND: Epithelial to mesenchymal transition (EMT) is a major determinant of cancer metastasis and is closely linked with TGF-β1. Intracellular proteins, including E. Cadherin, N. Cadherin and Vimentin are directly related to EMT that affect cell migration and adhesion; on the other hand, non muscle myosin (NM) has a central role in cytokinesis, migration and adhesion. OBJECTIVE: We aimed to explore the association of EMT and metastasis with TGF-β1 through regulation of non-muscle myosin II-A (NMII-A) and its interaction with Hexosamine Biosynthesis Pathway (HBP)...

The introduction of SiO2 particles as crosslinking points into hydrogels has been recognized as a suitable way for toughening hydrogels, due to their versatile functionalization and large specific surface area. However, chemically linked SiO2 nanocomposite hydrogels often exhibited negligible fatigue resistance and poor self-recoverable properties due to the irreversible cleavage of covalent bonds. Here, we proposed a novel strategy to improve stretchability, fatigue resistance and self-recoverable properties of hydrogels by using SiO2-g-poly(butyl acrylate) core-shell inorganic-organic hybrid latex particles as hydrophobic crosslinking centers for hydrophobic association...

Nuclear hormone receptors (NRs) regulate physiology by sensing lipophilic ligands and adapting cellular transcription appropriately. A growing understanding of the impact of circadian clocks on mammalian transcription has sparked interest in the interregulation of transcriptional programs. Mammalian clocks are based on a transcriptional feedback loop featuring the transcriptional activators circadian locomotor output cycles kaput (CLOCK) and brain and muscle ARNT-like 1 (BMAL1), and transcriptional repressors cryptochrome (CRY) and period (PER)...

Complete reendothelialization followed by inhibition of smooth muscle cell (SMC) proliferation is considered as an effective therapeutic option to prevent restenosis. We have designed poly(lactide-co-glycolide)-loaded bilayered nanoparticles (NPs) with the ability to sequentially release vascular endothelial growth factor (VEGF)-encoding plasmids from the outer layer and paclitaxel (PTX) from the core to promote endothelial regeneration as well as prevent restenosis. Comparing with conventional NPs, which release VEGF plasmid and PTX simultaneously, we expect that the bilayered NPs could release the VEGF plasmid more rapidly, followed by a delayed release of PTX, resulting in an efficient VEGF gene transfection, which ideally could promote reendothelialization and inhibit excessive SMC growth...

Sarcopenia is the degenerative loss of core muscle mass. It is an aspect of frailty, which is associated with increased rates of peri-operative harm. We assessed the association of the cross-sectional areas of abdominal muscles, including psoas, with survival during a median (IQR [range]) follow-up of 3.8 (3.2-4.4 [0.0-5.1]) years after scheduled endovascular (132) or open (5) abdominal aortic aneurysm repair in 137 patients. In multivariate analysis, mortality hazard (95%CI) was independently associated with: age, 1...

BACKGROUND: Histologic grade is the most important predictor of the clinical outcome of non-muscle invasive (Ta, T1) papillary urothelial carcinoma (NMIPUCa), but its ambiguous criteria diminish its power to predict recurrence/progression for individual patients. We attempted to find an objective and reproducible histologic predictor of NMIPUCa that correlates well with the clinical outcome. METHODS: A total of 296 PUCas were collected from the Departments of Surgical Pathology of 11 institutions in South Korea...

BACKGROUND: Core stabilization has been utilized for rehabilitation and prevention of lower limb musculoskeletal injuries. Previous studies showed that activation of the abdominal core muscles enhanced the hip muscle activity in hip extension and abduction exercises. However, the lack of the direct measurement and quantification of the activation level of the abdominal core muscles during the execution of the hip exercises affect the level of evidence to substantiate the proposed application of core exercises to promote training and rehabilitation outcome of the hip region...

In the present study, we sought to investigate the influence of high fat diet on the core clock genes and the muscle functional genes daily expression in the skeletal muscle of Chinese soft-shelled turtle. The turtles were fed by two diets including a control fat diet (the CON treatment, 7.98% lipid) and a high fat diet (the HFD treatment, 13.86% lipid) for six weeks and administrated by the photophase regimen of 24h light/dark (12L:12D) cycle. After the feeding trial experiment, we measured the daily expression levels of 17 core clock genes (Clock, Bmal1/2, NPAS2, Tim, Cry1/2, Per1/2, DBP, AANAT, NIFL3, BHLHE40, NR1D2, RORA, RORB, RORC) and 12 muscle functional genes (FBXO32, MBNL1, MSTN, Myf5, Myf6, MyoD, MyoG, MyoM1, PPARa, PDK4, Trim63, UCP3) in the skeletal muscle of the two treatments...
