PURPOSE: The risk of radiation exposure is considered to have increased in recent years. For convenience and simple administration, development of an effective orally administered radioprotective agent is highly desirable. The steroid 5-AED has been evaluated as both a radioprotector and a radiomitigator in mice and nonhuman primates, however, poor oral bioavailability has limited its development, while a variant compound, 17α-Ethinyl-androst-5-ene-3β, 17β-diol (EAD), exhibits significant oral bioavailability...

Bone marrow (BM) perivascular stromal cells and vascular endothelial cells (ECs) are essential for hematopoietic stem cell (HSC) maintenance, but the roles of distinct niche compartments during HSC regeneration are less understood. Here we show that Leptin receptor-expressing (LepR+) BM stromal cells and ECs dichotomously regulate HSC maintenance and regeneration via secretion of pleiotrophin (PTN). BM stromal cells are the key source of PTN during steady-state hematopoiesis because its deletion from stromal cells, but not hematopoietic cells, osteoblasts, or ECs, depletes the HSC pool...

BACKGROUND AND OBJECTIVES: The purpose of this study was to determine charges following unilateral mastectomy (UM) and bilateral mastectomy (BM) for patients with unilateral breast cancer (UBC). We hypothesized that BM may be associated with fewer charges over time. METHODS: A retrospective review was conducted of patients with UBC treated between 2006 and 2010 with UM and BM in a large healthcare system. Institutional billing data were investigated for 5 years postoperatively to calculate the immediate and subsequent charges of all inpatient and outpatient breast-related care associated with the initial diagnosis for a subset of patients identified using propensity score matching method...

Purpose: The purpose of this review was to provide detailed insights into the pathophysiology of myofibroblast-mediated fibrosis (scarring or late haze) after corneal injury, surgery, or infection. Method: Literature review. Results: The epithelium and epithelial basement membrane (EBM) and/or endothelium and Descemet's basement membrane (BM) are commonly disrupted after corneal injuries, surgeries, and infections. Regeneration of these critical regulatory structures relies on the coordinated production of BM components, including laminins, nidogens, perlecan, and collagen type IV by epithelial, endothelial, and keratocyte cells...

Purpose: To investigate changes of β-zone parapapillary atrophy (PPA) during axial elongation. Methods: Change of β-zone PPA was evaluated by spectral-domain optical coherence tomography (SD-OCT) in myopic children for 2 years, prospectively. Using the infrared images acquired by a fixed scan circle in the glaucoma progression analysis (GPA) mode, the retinal pigment epithelial opening (RPEO) and the clinical disc margin (CDM) were manually delineated. The area and position of β-zone PPA was calculated as the differences from those of the RPEO and CDM, respectively...

Atherosclerosis is a complex disease that involves alterations in lipoprotein metabolism and inflammation. Protein and lipid glycosylation events, such as sialylation, contribute to the development of atherosclerosis and are regulated by specific glycosidases, including sialidases. To evaluate the effect of the sialidase neuraminidase 1 (NEU1) on atherogenesis, here we generated apolipoprotein E (ApoE)-deficient mice that express hypomorphic levels of NEU1 ( Neu1hypo Apoe-/- ). We found that the hypomorphic NEU1 expression in male Apoe-/- mice reduces serum levels of very-low-density lipoprotein (VLDL) and LDL cholesterol, diminishes infiltration of inflammatory cells into lesions, and decreases aortic sinus atherosclerosis...

Mesenchymal stem cells (MSCs) are promising cell sources for regenerative medicine. Growing evidence has indicated that mechanical stimuli are crucial for their lineage-specific differentiation. However, the effect of mechanical loading on redox balance and the intracellular antioxidant system in MSCs was unknown. In this study, human bone marrow-derived MSCs (BM-MSCs) were subjected to cyclic stretch at the magnitude of 2.5%, 5%, and 10%. Cell proliferation, intracellular reactive oxygen species (ROS), expression of antioxidant enzymes, and osteogenic differentiation were evaluated...

BACKGROUND: Human bone marrow mesenchymal stem cells (hBM-MSC) have the ability of differentiating into chondrocytes and osteoblasts. miR-182-5p promotes osteoclastogenesis and bone metastasis by up-regulating the expression of parathyroid hormone-like hormone (PTHLH). However, the function of miR-182-5p in chondrogenesis is still unknown. METHODS: Mimic or inhibitor of miR-182-5p were used to upregulate or knock-down miR-182-5p expression respectively. We analyzed chondrogenesis by Safranin O staining and Blyscan™ Sulfated Glycosaminoglycan Assay...

Background: Non-small cell lung cancer (NSCLC) patients frequently develop brain metastases (BM), even though the initial imaging with brain CT or MRI was negative. Stage III patients have the highest risk to develop BM, with an incidence of approximately 30%. BM can lead to neurocognitive disorders, loss of quality of life (QoL), and they are the most important factors influencing patient's overall survival (OS). Although a radical local treatment of BM may be possible with primary radiosurgery or after resection, the prognosis often remains poor...

BACKGROUND: We reported the results of an Italian large retrospective analysis that evaluated the effectiveness and safety of T-DM1 in 'field-practice' breast cancer patients. We performed a sub-analysis to investigate the clinical activity of T-DM1 in patients with brain metastases (BMs). METHODS: The records of 87 adult women with HER2-positive breast cancer and BMs treated with T-DM1 were reviewed. Their clinical outcomes were compared with those of 216 patients without central nervous system (CNS) involvement...

In this study, poly(3-hydroxybutyrate) (PHB) production from a newly isolated obligate alkaliphilic Bacillus marmarensis DSM 21297 was investigated to evaluate the ability of obligate alkaliphilic strain to produce a biopolymer. Additionally, electrospun nanofibers from B. marmarensis PHB (Bm-PHB) were generated using Bm-PHB/polycaprolactone (PCL) blend to evaluate the applicability of Bm-PHB. According to the experimental results, the metabolic activity of B. marmarensis decreased the pH of the medium by generating H+ ions to initiate Bm-PHB production, which was achieved at pH below 9...

Despite progress in the treatment of MM, including the use of high-dose chemotherapy and autologous stem cell transplantation, a considerable proportion of patients are refractory to all therapies. This resistance is related to the molecular genetic heterogeneity in MM cells as well as to the contributions from the BM, which is one of the key determinants of treatment outcome. Our previous studies using fluorescent tracers revealed that MM heterogeneity is correlated with the presence of quiescent stem-like cancer cells, which prefer to reside within the osteoblastic niche of the BM...

The fatality of non-small-cell lung cancer (NSCLC) and the role of the cancer microenvironment in its resistance to therapy are long recognized. Accumulating data allocate a significant role for mesenchymal stem cells (MSCs) in the malignant environment. Previously, we have demonstrated that MSCs from NSCLC metastatic bone marrow (BM) niche deleteriously affected NSCLC cells. Here, we have decided to examine the effect of MSCs from the primary niche of the lung (healthy or adjacent to tumor) on NSCLC phenotype...

Two-dimensional (2D) organic-inorganic perovskite semiconductors with natural multi-quantum well structures and confined 2D excitons are intriguing for the study of strong exciton-photon coupling, due to their large exciton binding energy and oscillation strength. This strong coupling leads to a formation of the half-light half-matter bosonic quasiparticle called exciton-polariton, consisting of a linear superposition state between photonic and excitonic states. Here, we demonstrate room temperature strong coupling in exfoliated wavelength-tunable 2D organic-inorganic perovskite semiconductors embedded into a planar microcavity, exhibiting large energetic splitting-to-linewidth ratios (>34...
