Article Abstract
Objective: To study serum concentration and mRNA expression of interleukin-13 (IL-13) in children with steroid-responsive nephrotic syndrome (SRNS) and the effect of methylprednisolone pulse therapy (MPT) on IL-13 expression.
Methods: Twenty-eight children with SRNS were enrolled in this study. Serum protein level of IL-13 was measured using ELISA and IL-13 mRNA expression in peripheral blood mononuclear cells (PBMC) was detected with RT-PCR before MPT, 2 and 5 days after MPT, and 2 weeks after disappearance of proteinuria following MPT. Twenty-four urinary protein was measured with the biuret assay. Twenty healthy children were used as controls.
Results: Serum IL-13 levels (38.48 +/- 13.01 pg/mL vs 5.18 +/- 2.71 pg/mL) and PBMC IL-13 mRNA expression (1.31 +/- 0.23 vs 0.36 +/- 0.07) before MPT in SRNS patients were significantly higher than in the controls. After 5 days of MPT and 2 weeks after disappearance of proteinuria following MPT, serum IL-13 levels (15.33 +/- 7.81 and 5.35 +/- 2.12 pg/mL respectively) and PBMC IL-13 mRNA expression (0.89 +/- 0.26 and 0.33 +/- 0.08 respectively) were significantly reduced (P < 0.01). Serum IL-13 levels and PBMC IL-13 mRNA expression in SRNS patients 2 weeks after disappearance of proteinuria following MPT were reduced to control levels, but remained at a higher level than controls 5 days after MPT. A positive correlation was found between serum levels of IL-13 and 24-hour urinary protein in SRNS patients before (r=0.75, P < 0.01) and after 2 and 5 days of MPT (r=0.68, r=0.71 respectively; P < 0.05).
Conclusions: Serum IL-13 levels and PBMC IL-13 mRNA expression in children with SRNS increase. MPT can inhibit the expression of protein and mRNA of IL-13 in these patients.

Mesenchymal stem cells (MSCs) are promising candidates for regenerative therapies due to their self-renewal and differentiation capabilities. Pathological microenvironments expose MSCs to senescence-inducing factors such as reactive oxygen species (ROS), resulting in MSC functional decline and loss of stemness. Oxidative stress leads to mitochondrial dysfunction, a hallmark of senescence, and is prevalent in aging tissues characterized by elevated ROS levels.

Background: To determine the role of N-methyladenosine (mA) modification in the tumor immune microenvironment (TIME), as well as their association with lung adenocarcinoma (LUAD).
Methods: Consensus clustering was performed to identify the subgroups with distinct immune or mA modification patterns using profiles from TCGA. A risk score model was constructed using least absolute shrinkage and selection operator regression and validated in two independent cohorts and LUAD tissue microarrays.

Purpose: Changes in choroidal thickness (ChT) are proposed to predict myopia development but evidence is mixed. We investigated time courses of choroidal responses, following different types of dynamic artificial stimulation in chicks with and without spectacle lenses, as well as changes in retinal dopamine metabolism and expression of candidate genes.
Methods: Chicks were kept in an arena surrounded by computer monitors presenting dynamic checkerboard fields of small, medium and large size.
