Quantitative Iron Neuroimaging Can Be Used to Assess the Effects of Minocycline in an Intracerebral Hemorrhage Minipig Model.

Iron-mediated toxicity is a key factor causing brain injury after intracerebral hemorrhage (ICH). This study was performed to investigate the noninvasive neuroimaging method for quantifying brain iron content using a minipig ICH model and assess the effects of minocycline treatment on ICH-induced iron overload and brain injury. The minipig ICH model was established by injecting 2 ml of autologous blood into the right basal ganglia, which were then subjected to the treatments of minocycline and vehicle.

Increased levels of serum pigment epithelium-derived factor aggravate proteinuria via induction of podocyte actin rearrangement.

Purpose: To assess the role of serum pigment epithelium-derived factor (PEDF) in the occurrence and development of proteinuria and renal dysfunction and determine its relevant signaling pathway.

Methods: We analyzed serum PEDF, creatinine, the urinary albumin-to-creatinine ratio, and renal morphology of normal or streptozotocin (STZ)-induced diabetic mice, before and after treatment with PEDF. In vitro, podocytes were stimulated with PEDF under normal or high-glucose conditions; permeability was measured by the transwell assay with fluorescein isothiocyanate (FITC)-dextran; and F-actin cytoskeleton was analyzed by phalloidin staining.

The correlation between transcutaneous oxygen tension and microvascular complications in type 2 diabetic patients.

Aims: This study aimed to assess whether transcutaneous oxygen tension (TcPO) was associated with the presence of microvascular complications in type 2 diabetic (T2D) patients and whether TcPO could act as an independent risk factor for predicting the occurrence of microvascular events in these patients.

Methods: We recruited 436 patients with T2D. Based on the presence of diabetic kidney disease, diabetic retinopathy, and/or diabetic peripheral neuropathy, the patients were divided into groups with and without microvascular complications.

Identification and verification of PRDX1 as an inflammation marker for colorectal cancer progression.

Chronic inflammation contributes to high risk of colorectal cancer (CRC) development. Thus, discovering inflammation biomarkers for monitoring of CRC progression is necessary. In this study, we performed isobaric tags for relative and absolute quantitation-based proteomic assay on CRC tissues and paired normal mucosal tissues to identify key components in CRC pathogenesis.

Two novel serum biomarkers for endometriosis screened by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry and their change after laparoscopic removal of endometriosis.

Objective: To explore novel endometriosis serum biomarkers by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS).

Design: First, we aimed to discover the potential biomarkers of endometriosis by SELDI-TOF-MS. Second, blinded test was performed to characterize the effectiveness of the model by examining the sensitivity and specificity.
