Oral-Health-Related Quality of Life and Cosleeping: The Role of Nocturnal Breastfeeding

2021

The purpose of this paper is to analyse the association between cosleeping and the number of breastfeeding sessions in infants, OHRQoL of the child and the family, and the DMFT Child’s index. The sample comprised 273 children (2–4 years old). In addition to the clinical examination of the child to assess the DMFT Index, the mother was requested to complete a questionnaire to collect data about the breastfeeding practice, diet, dental hygiene, dental check-ups, quality of the child’s oral life, and family impact (ECOHIS Scale). The children’s OHRQoL is positively correlated with number of night-time breastfeeding sessions at 12 months (r2 = 0.40 **), DMFT index (r2 = 0.60 **), impact family …

Root repair after injury from mini-screw

2005

Mini-implants and mini-screws are commonly used in orthodontics to provide extra anchorage. One potential insertion site is between the roots in the alveolar process, which results in a risk of damaging the roots of neighbouring teeth. In an animal-experimental study, 20 mini-screws (bracket screw bone anchors, BSBAs) were inserted into the mandible of five beagle dogs. Each dog received two BSBAs in each lower quadrant, between the roots of the second and third, and third and fourth premolars. Sequential point labelling was performed every 6 weeks with vital stains, and apical X-rays were taken every 6 weeks. Radiographic examination demonstrated damage at three roots because of insertion …

An Agents and Artifacts Approach to Distributed Data Mining

2013

This paper proposes a novel Distributed Data Mining (DDM) approach based on the Agents and Artifacts paradigm, as implemented in CArtAgO [9], where artifacts encapsulate data mining tools, inherited from Weka, that agents can use while engaged in collaborative, distributed learning processes. Target hypothesis are currently constrained to decision trees built with J48, but the approach is flexible enough to allow different kinds of learning models. The twofold contribution of this work includes: i) JaCA-DDM: an extensible tool implemented in the agent oriented programming language Jason [2] and CArtAgO [10,9] to experiment DDM agent-based approaches on different, well known training sets. A…

Formation and Transformations of Organic Salt Hydrates: Four Encenicline Hydrochloride Monohydrates and Respective Isostructural Desolvates

2018

Encenicline hydrochloride (Enc-HCl) crystallizes in four different monohydrate phases, but at the same time crystallization in a nonsolvated phase is not observed, indicating that water plays a crucial role in guiding the crystallization process and ensuring structure stability. All monohydrate phases show exceptionally high stability, and the main structural motif stays intact even after dehydration, leading to isostructural (for I and II) or isomorphic (for III) desolvates. Three monohydrate phases with determined crystal structure information consists of Enc-HCl-water hexamers that are stacked into similar slabs, that are further packed identically in monohydrates I, II, and III. The fea…

Chemical conjugation of dexamethasone to a polyaspartamide and in vitro evaluation studies

2004

Two macromolecular conjugates of dexamethasone containing different drug amounts were synthesized using PHEA as the polymeric carrier and a succinic group as spacer. The content of linked drug was equal to 25.3% w/w (conjugate A) and 12.7% w/w (conjugate B). Both polymeric conjugates, unlike the free drug, were water-soluble and the amount of unlinked drug was evaluated to be approximately about 0.01% w/w. Both conjugates were relatively stable in vitro at pH 7.4 whereas in the presence of esterase only the conjugate B was able to release drug under the used experimental conditions. This dissimilar behavior has been attributed to the distinct macromolecular conformations assumed in aqueous …

Transparent thermoplastic polyurethanes based on aliphatic diisocyanates and polycarbonate diol

2016

Segmented thermoplastic polyurethanes (PUs) were synthetized using polycarbonate diol as soft segment with a molar mass of 500 and as a hard segment 1,5-pentanediol with a combination of isophorone diisocyanate (IPDI) and hexamethylene diisocyanate (HDI). Differential scanning calorimetry, differential mechanical analysis, Fourier transform infrared-attenuated total reflection spectroscopy, haze, transmittance, hardness, tensile properties and retention of tensile properties tests were employed to characterize the different PUs. The results of this study show that IPDI/HDI relation has a significant impact on the phase mixing, crystallinity and therefore on the PU’s properties. The variati…
