P-N depleted bulk BiOBr/α-Fe2O3 heterojunction (DBH) nanostructures with the growth of (001) BiOBr facets were prepared via a simple hydrothermal method. BiOBr possesses an average thickness of around 50 nm and shows preferential exposure of the (001) facets. α-Fe2O3 nanoparticles, with an average diameter of 5 nm, are attached on the surface of BiOBr as 20-50 nm clusters with an intimate contact interface. Such DBH nanostructures show high hydrogen evolution, and 193 mmol g(-1) of H2 is produced with DBH containing 1 wt% Pt, which is 6...

BACKGROUND: Cellular therapies for immunomodulation in vascularized composite allotransplantation (VCA) have gained importance due to their potential minimization of immunosuppression. Adipose-derived mesenchymal stem cells (AD-MSCs) especially have shown encouraging potential. We investigated the influence of timing and frequency of AD-MSC-treatment on immunologic and graft survival as well as graft vasculopathy (GV) outcomes after VCA. METHODS: Lewis (LEW) rats received full-mismatched Brown Norway (BN) rat hindlimb transplants...

OBJECTIVE: To investegate the role of calcineurin (CaN) and its downstream nuclear factor of activated T-cells (NFATc3) in abdominal aorta restenosis following balloon dilatation in rats. METHODS: SD rats were randomly divided into sham-operated group, balloon group and cyclosporine A (CsA) group. The rats in the latter two groups were subjected to abdominal aorta injury with balloon dilatation, and those in CsA group were treated with CsA at the daily dose of 12...

Neo-intima development and atherosclerosis limit the long-term use of vein grafts for revascularization of ischemic tissues. Recently, studies have confirmed that proliferating cell nuclear antigen (PCNA) plays an important role in cell proliferation. Our research confirmed that 28 days after vein transplantation, PCNA expression increases significantly. Using rabbits, rather than rodents, for a more representative model of human vein grafts, we aimed to establish a time course of changes in cell proliferation and apoptosis using morphometric and immunohistochemical analyses, western blot, terminal deoxynucleotidyl transferase dUTP nick end labeling, and transmission electron microscopy (TEM)...

In situ precision synthesis of monodisperse hairy plasmonic nanoparticles with tailored dimensions and compositions by capitalizing on amphiphilic star-like diblock copolymers as nanoreactors are reported. Such hairy plasmonic nanoparticles comprise uniform noble metal nanoparticles intimately and perpetually capped by hydrophobic polymer chains (i.e., "hairs") with even length. Interestingly, amphiphilic star-like diblock copolymer nanoreactors retain the spherical shape under reaction conditions, and the diameter of the resulting plasmonic nanoparticles and the thickness of polymer chains situated on the surface of the nanoparticle can be readily and precisely tailored...

Calcium is an important ion in cell signaling, hormone regulation, and bone health. Its regulation is complex and intimately connected to that of phosphate homeostasis. Both ions are maintained at appropriate levels to maintain the extracellular to intracellular gradients, allow for mineralization of bone, and to prevent extra skeletal and urinary calcification. The homeostasis involves the target organs intestine, parathyroid glands, kidney, and bone. Multiple hormones converge to regulate the extracellular calcium level: parathyroid hormone, vitamin D (principally 25(OH)D or 1,25(OH)2D), fibroblast growth factor 23, and α-klotho...

The purpose of this study was to compare the cardiovascular health of Black and White breast cancer patients undergoing adjuvant treatment. Baseline data from a cohort study of Black (n = 45) and White (n = 101) breast cancer patients initiating aromatase inhibitor treatment were analyzed. Participants had a cardiovascular health assessment, including carotid intimal medial thickness measurement, donated a blood sample, and completed a questionnaire. Atherosclerotic cardiovascular disease (ASCVD) event risk scores were calculated...

Evidence suggests that women who suffer from intimate partner violence (IPV) and posttraumatic stress disorder (PTSD) have structural and functional alterations in specific brain regions. Yet, little is known about how brain connectivity may be altered in individuals with IPV, but without PTSD. Women exposed to IPV (n = 18) and healthy controls (n = 18) underwent structural brain imaging using a Siemens 3T MRI. Global and regional brain network connectivity measures were determined, using graph theory analyses...

The present study investigated the contribution of bone marrow-derived mesenchymal stem cells (BM‑MSCs) to neointimal formation, and whether endothelial‑like cells (ELCs) differentiated from BM‑MSCs could attenuate intimal hyperplasia following vascular injury. BM‑MSCs were isolated from rat femurs and tibias and expanded ex vivo. Differentiation into ELCs was induced by cultivation in the presence of 50 ng/ml vascular endothelial growth factor (VEGF). MSCs and ELCs were labeled with BrdU and injected via the femoral vein on the day of a balloon‑induced carotid artery injury...

BACKGROUND/OBJECTIVES: While adiposity and hepatic steatosis are linked to cardiovascular risk in developed countries, their prevalence and impact in low-income countries are poorly understood. We investigated the association of anthropomorphic variables and hepatic steatosis with cardiometabolic risk profiles and subclinical cardiovascular disease (CVD) in a large rural Indian cohort. METHODS: In 4691 individuals in the Birbhum Population Project in West Bengal, India, we performed liver ultrasonography, carotid ultrasound and biochemical and clinical profiling...

PURPOSE: The present study aimed to explore the regulating effect of Toll-like receptor 4 (TLR4) on intimal hyperplasia in rat vein grafts. METHODS: Rat models of external jugular vein carotid artery bypass grafting were established. Afterward, TLR4 small interfering RNA (siRNA) recombinant plasmids were constructed, which were transfected into rat vein graft bypass to study the effect of TLR4 silencing on intimal hyperplasia and to explore the underlying mechanisms...

BACKGROUND/OBJECTIVES: Carotid intimal media thickness (IMT) and coronary calcium scores (CCS) are thought to reflect atherosclerotic burden. The validity of this assumption for IMT is challenged by recent meta-analyses; for CCS by absence of a relationship between negative scores, and freedom of future events. As such, we considered evaluation of the relationship between tissue IMT and CCS, and extend of atherosclerotic disease relevant. METHODS: Analyses were performed on donor aortas obtained during renal graft procurement, and on coronary arteries collected during heart valve procurement for tissue donation...

OBJECTIVE: Macrophages are involved in venous thrombus (VT) resolution and vein wall remodeling. This study was undertaken to identify variations in macrophage phenotypes in thrombi and vein wall in multiple models of VT to clarify the natural history of macrophage polarization in clearance of VT. We also sought to demonstrate the feasibility of macrophage phenotyping in human VT. METHODS: Established murine models of VT were used to mimic the clinical spectrum of human VT (stasis and nonstasis models)...

Diabetic keratopathy is an ocular complication that occurs with diabetes. In the present study, the effect of diabetic keratopathy on corneal optical density, central corneal thickness, and corneal endothelial cell count was investigated. One hundred and eighty diabetic patients (360 eyes) were enrolled in the study during the period from March, 2012 to March, 2013. The patients were divided into three age groups: <5, 5-10 and >10 years, with 60 patients per group (120 eyes). During the same period, 60 healthy cases (120 eyes) were selected and labeled as the normal control group...

MATERIAL AND METHODS: In 71 postmenopausal women divided in two groups: group 1, IMT > 1 mm and group 2, IMT ≤ 1 mm, blood pressure, body mass index (BMI), waist hip ratio (WHR), visceral and subcutaneous fats and carotid IMT were analyzed. Descriptive statistics were used and the comparison among those with abnormal and normal IMT was carried out using Mann-Whitney U test; also Spearman's correlation analysis was done...
