PURPOSE: Four incident reports involving missed doses of myeloid growth factors (MGFs) triggered the need for an outcome-driven initiative. From March 1, 2015, to February 29, 2016, at University of California Irvine Health Chao Infusion Center, 116 of 3,300 MGF doses were missed (3.52%), including pegfilgrastim, filgrastim, and sargramostim. We hypothesized that with the application of Lean Six Sigma methodology, we would achieve our primary objective of reducing the number of missed MGF doses to < 0...

Diabetes mellitus induces a reduction in skeletal muscle mass and strength. Strength training is prescribed as part of treatment since it improves glycemic control and promotes increase of skeletal muscle mass. The mechanisms involved in overload-induced muscle hypertrophy elicited at the establishment of the type I diabetic state was investigated in Wistar rats. The purpose was to examine whether the overload-induced hypertrophy can counteract the hypotrophy associated to the diabetic state. The experiments were performed in oxidative (soleus) or glycolytic (EDL) muscles...

The fluorolytic sol-gel synthesis for binary metal fluorides (AlF₃, CaF₂, MgF₂) has been extended to ternary and quaternary alkaline earth metal fluorides (CaAlF₅, Ca₂AlF₇, LiMgAlF₆). The formation and crystallization of nanoscopic ternary CaAlF₅ and Ca₂AlF₇ sols in ethanol were studied by (19)F liquid and solid state NMR (nuclear magnetic resonance) spectroscopy, as well as transmission electron microscopy (TEM). The crystalline phases of the annealed CaAlF₅, Ca₂AlF₇, and LiMgAlF₆ xerogels between 500 and 700 °C could be determined by X-ray powder diffraction (XRD) and (19)F solid state NMR spectroscopy...

The effects of sodium dodecyl sulfate (25 mg/ml) and Triton X-100 (12.5 mg/ml and 25 mg/ml) on the HaCaT immortalized keratinocytes exposed to these surfactants for 48 h were studied. Using shotgun proteomics, a comparative analysis of the proteomic profiles of control and experimental cells after surfactants exposure was carried out. 260 common proteins were identified in control and experimental cells; 33 proteins were found in cells exposed to all three treatments, but not in control cells. These 33 proteins apparently reflect a nonspecific (universal) response of cells to toxic damage by the surfactants...

We analyze the performance of a free-space optical (FSO) link affected by atmospheric turbulence and line-of-sight (LOS) blockage. For this purpose, the atmospheric turbulence induced fading is modeled by the ℳ distribution, which includes the Gamma-Gamma distribution as special case. We exploit the fact that the physical interpretation of the ℳ distribution allows to split the optical energy through the propagation link into three different components: two coherent components and one incoherent scatter component...

OBJECTIVES: Graft flow in coronary artery bypass grafting (CABG) may be determined by the anatomical and pathological characteristics of the coronary artery and target myocardium. Our goal was to explore the relationships between graft flow and the cardiac/coronary parameters in CABG. METHODS: We enrolled 63 patients who underwent isolated CABG and were examined by cardiac computed tomography. We statistically analysed the correlation between the intraoperative graft flow, such as the mean graft flow (MGF) or the pulsatile index (PI), and the computed tomography scan-based anatomy of the coronary artery tree and the left ventricle in 104 individually bypassed grafts...

AIMS: Severe hypoxia always inhibits the cell proliferation, osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs), and hinders bone defect repair. Herein we explored the effects of mechano-growth factor (MGF) E peptide on the proliferation and osteogenic differentiation of BMSCs under severe hypoxia. MATERIALS AND METHODS: CoCl2 was utilized to simulate severe hypoxia. MTS was used to detect cell viability. Cell proliferation was verified through flow cytometry and EdU assay...

Notch signaling is involved in osteogenic differentiation; however, its role differs depending on cell type and differentiation stage. Here, we investigated the involvement of Notch signaling in the osteogenic differentiation of retinoic acid-treated embryoid bodies derived from mouse gingival fibroblast-derived induced pluripotent stem cells (mGF-iPSCs). When cultured in osteogenic media, mGF-iPSCs showed an increase in their expression of osteogenic marker genes and deposited a mineralized matrix. Furthermore, increased levels of mRNA for Notch1, Notch2, and Hey1 were observed...

In order to study the influence of disuse and aging on skeletal muscle homeostasis, different human models were employed. Effects of chronic disuse were investigated in elderly patients suffering from uni-lateral hip-osteoarthritis, whereas the effect of short-term disuse (4 and 14 days of unilateral lower limb immobilisation) was assessed in healthy young and old individuals. In summary, chronic muscle disuse in the elderly was associated with marked quantitative as well as qualitative neuromuscular impairments...

Evidence suggests that chiropractic manipulation might exert positive effects in osteoporotic patients. The aim of this study was to evaluate the effects of chiropractic manipulation on bone structure and skeletal muscle in rats with bone loss caused by ovariectomy (OVX). The 6-month old Sprague-Dawley rats at 10 weeks following OVX or sham operation (Sh) did not suffer chiropractic manipulation (NM group) or were submitted to true chiropractic manipulation using the chiropractic adjusting instrument Activator V(®) three times/week for 6 weeks as follows: Force 1 setting was applied onto the tibial tubercle of the rat right hind limb (TM group), whereas the corresponding left hind limb received a false manipulation (FM group) consisting of ActivatorV(®) firing in the air and slightly touching the tibial tubercle...

Mechano growth factor (MGF) is a splice variant of IGF-1 first described in skeletal muscle. MGF induces muscle cell proliferation in response to muscle stress and injury. In control mice we found endogenous expression of MGF in neurogenic areas of the brain and these levels declined with age. To better understand the role of MGF in the brain, we used transgenic mice that constitutively overexpressed MGF from birth. MGF overexpression significantly increased the number of BrdU+ proliferative cells in the dentate gyrus (DG) of the hippocampus and subventricular zone (SVG)...

Previous studies have attached more importance to growth factors in treating cartilage degeneration and osteoarthritis (OA). Here, the capability of mechano growth factor-C24E (MGF) to prevent osteoarthritic cartilage degeneration was evaluated in vitro and in vivo. Using in vitro cultured human OA chondrocytes treated with 10-60 ng/ml MGF for 12 h, we detected the cell proliferation, migration and anabolism of OA chondrocytes. The unfolded protein response (UPR) and the proteins characteristic of OA pathology, such as TGF-β, Smad3 and HIF-2α of OA chondrocytes, were also detected by western blotting...

This work studied the performance of a laboratory-scale microbial fuel cell (MFC) using a bioanode that consisted of treated clinoptilolite fine powder coated onto graphite felt (TC-MGF). The results were compared with another similar MFC that used a bare graphite felt (BGF) bioanode. The anode surfaces provided active sites for the adhesion of the bacterial consortium (NAR-2) and the biodegradation of mono azo dye C.I. Acid Red 27. As a result, bioelectricity was generated in both MFCs. A 98% decolourisation rate was achieved using the TC-MGF bioanode under a fed-batch operation mode...
