Cell-derived extracellular matrix (ECM) scaffolds have received considerable interest for tissue engineering applications. In this study, ECM scaffolds derived from mesenchymal stem cell (MSC), chondrocyte, and fibroblast were prepared by culturing cells in a selectively removable poly(lactic-co-glycolic acid) (PLGA) template. These three types of ECM(More)
BACKGROUND The aim was to evaluate the risk for major hemorrhage complications (MHC) prior to percutaneous renal biopsy and apply a specific procedure in high-risk patients to decrease their incidence. Hemorrhage complications that required blood transfusion or other interventions were diagnosed as MHC. METHODS One retrospective (Group A, n = 1314) and(More)

and Applied Analysis 3 Theorem 2.3. Suppose that f : R ×Rd×Rd → ×Rd is continuous, a, b : R → R are continuous, strictly increasing functions satisfying a 0 b 0 0. Let constants M > 0 and q ∈ 0, 1 exist such that for n ∈ Z, a |x| ≤ V t, x ≤ b |x| , t ∈ R, x ∈ R, 2.3 V n 1, x n 1 ≤ qV n, x n , 2.4 V t, x t ≤ MV n, x n , for t ∈ n, n 1 . 2.5 Then the trivial(More)
The paper deals with convergence and stability of the semi-implicit Euler method with variable stepsize for a linear stochastic pantograph differential equation(SPDE). It is proved that the semi-implicit Euler method with variable stepsize is convergent with strong order p = 1 2. The conditions under which the method is mean square stability are determined(More)
BACKGROUND Interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) have important functions in injury and repair processes of glomerular intrinsic cells. A study was conducted to analyze the urinary VEGF/creatinine (CR) and IL-6/CR levels in simple hematuria patients after excluding the interference of creatinine. We aimed to investigate the(More)
Renal hematuria is caused by glomerular disease. Under pathological conditions, the distribution of interleukin-6 (IL-6) in kidney tissue is abnormal and urinary IL-6 levels are increased. Abnormal IL-6 secretion promotes the hyperplasia of mesangial cells and matrix and, thus, affects the permeability of the glomerular filtration membrane. Therefore, the(More)
