Abstract Orthodontic tooth movement is triggered by orthodontic force loading on the periodontal ligament and is achieved by alveolar bone remodeling, which is regulated by intimate crosstalk between osteoclastogenesis and osteoblast differentiation. Whether the communication between osteoclasts and osteoblasts is influenced by orthodontic compression stress requires further clarification. In this study, osteoclasts were differentiated for 10 days. On day 4 of differentiation, the number of pre-osteoclasts peaked, as determined by the increased expression of RANK and the number of multinucleated cells. After 24 h of compression stress loading, on day 4, the number of osteoclasts increased, and the optimal magnitude of… More >

Abstract Emerging communication and computing technologies such as social media, Internet of Things and big data provide great opportunities to improve information management systems for emergency operations. This paper studies the issues of information management at China’s Emergency Operations Center (EOC), and proposes a data-driven knowledge management system (KMS) to support decisionmaking, coordination, and collaboration within EOCs and with the public. In the proposed KMS, big data analytics is employed to gather and analyze information from different knowledge domains and track how a crisis evolves in physical world and in cyber space. The proposed system aims at improving situation awareness of… More >

Abstract Background: Telemedicine is a rapidly evolving form of modern information and communication technology used to deliver clinical services and educational activities.
Objective: The aim of this article is to report and analyze our experience with transatlantic consultation via videoconferencing in pediatric cardiology.
Methods: In February, 2013, videoconferencing project was launched between a medium-volume pediatric cardiac center in Bratislava, Slovakia and subspecialty experts from a high-volume pediatric cardiac program at The Children’s Hospital of Philadelphia (CHOP), USA. During 1.5–2 hours videoconferences, 2–3 patients with similar complex clinical scenarios were presented to CHOP experts. The main goal of the project was consultation… More >

Abstract Objective: Pheochromocytoma and paraganglioma (extra-adrenal pheochromocytoma) are rare neuroendocrine tumors that arise from the neuroendocrine cells. Chronic hypoxia is known as a possible cause, and a strong link between cyanotic congenital heart disease and these tumors has been reported. However, reports of phechromocytoma/paraganglioma in Fontan patients were scarce. We herein report seven cases of phechromocytoma/paraganglioma after Fontan operation at a single tertiary center.
Methods: We retrospectively reviewed medical records and imaging studies who diagnosed as phechromocytoma/paraganglioma after Fontan operation in Seoul National University Children’s Hospital.
Results: Seven patients were identified during follow-up after Fontan operation, and the prevalence was 2.5%… More >

Abstract In a previous paper we described a pronounced increase of apoptotic nuclei in rat corpus luteum of pregnancy whose programmed chromatin degeneration was induced by the progesterone antagonist mifepristone. Those observations encouraged us to study the apoptotic nuclear membrane during pregnancy and after parturition and pup removal, by using a freeze-fracture technique which allows us to observe ‘en face’ the nuclear envelop and also permits nuclear pore counting. This study was complemented with the TUNEL assay (TdT-mediated dUTP nick-end labelling). Changes in nuclear pores during pregnancy begin with an intense reduction in number but still showing an even distribution on… More >

Abstract Nonspecific acid phosphatases are a group of enzymes whose activity increases the availability of exogenous and endogenous orthophosphate either through extra- or intracellular hydrolysis of phosphate compounds. Our study demonstrates the activity of acid phosphatases in the filamentous freshwater alga Stigeoclonium tenue. These enzymes were detected following a cerium-based method in which cerium was used as an orthophosphate-capture reagent. In thalli from S. tenue from the natural environment, acid phosphatases were found in the longitudinal cell wall, plasmalemma, and vacuole. In thalli from Bold’s Basal Medium culture, these enzymes were found mainly in the plasmalemma; they were scarce in the… More >
