conclusion superselective tae for lgi bleeding has a high success and low complication rate. there are no statistical correlations between the clinical success rate and several variables, including embolic material, embolization site, and anticoagulant or antiplatelet medication. patients and methods fifty-two patients who underwent superselective tae for lgi bleeding between 2003 and 2011 were...

background: recently, there has been interest in non‑mammalian collagen sources such as fish collagen in the development of biomatrices and scaffolds for periodontal regeneration. in the present study, a novel collagen barrier membrane of fish origin was assessed in the treatment ofperiodontal intra‑bony defects. materials and methods: ten systemically healthy chronic periodontitis patients hav...

BACKGROUND Bleeding among patients with acute myocardial infarction (AMI) is associated with worse long-term outcomes. Although the mechanism underlying this association is unclear, a potential explanation is that withholding antiplatelet therapies long beyond resolution of the bleeding event may contribute to recurrent events. METHODS AND RESULTS We examined medication use at discharge, 1, 6...

Let U be an open subset of a locally compact metric ANR X and let f : U → X be a continuous map. In this paper we study the fixed point index of the map that f induces in the n-symmetric product of X, Fn(X). This index can detect the existence of periodic orbits of period ≤ n of f , and it can be used to obtain the Euler characteristic of the n-symmetric product of a manifold X, χ(Fn(X)). We co...

Some problems in differential equations evolve towards Topology from an analytical origin. Two such problems will be discussed: the existence of solutions asymptotic to the equilibrium and the stability of closed orbits of Hamiltonian systems. The theory of retracts and the fixed point index have become useful tools in the study of these questions. Retractos, ı́ndice de punto fijo y ecuaciones d...

The objective of this study was to evaluate the effectiveness of oral hygiene instruction media on periodontal health in hearing impaired children over a period of three months. The study was carried out among 66 hearing impaired children (aged 6-10 years). The children were randomly divided into 4 groups by oral hygiene instruction media type: video presentation group, illustrated book group, ...

OBJECTIVE To compare the efficacy of an oscillating-rotating power toothbrush with a novel brush head incorporating angled CrissCross bristles (Oral-B Triumph with SmartGuide with Oral-B CrossAction brush head) versus a sonic toothbrush (Sonicare DiamondClean) for plaque and gingivitis reduction over a six-week period. METHODS This was a single-center, randomized, examiner-blind, two-treatmen...

Managing large volume points clouds data generated from laser scanner is a challenging problem in Geographic Information System (GIS) and spatial database. Based on analyzing the pros and cons of the existing management methods, this paper presents a method to manage lidar data in databases based on the Hilbert space-filling curve. Each lidar data point (X, Y, and Z) is encoded (indexed) by the...
