Marginal and Internal Precision of Zirconia Four-Unit Fixed Partial Denture Frameworks Produced Using Four Milling Systems
2021
Background: CAD/CAM systems enable the production of fixed partial dentures with small and reproducible internal and marginal gaps. Purpose: The purpose of this study was to evaluate the reproducibility of the marginal and internal adaptations of four-unit fixed partial denture frameworks produced using four CAD/CAM systems. Materials and Methods: Prepared dies of a master model that simulated the loss of the first left molar were measured. Fifteen frameworks were manufactured using four CAD/CAM systems (A–D). The internal fit was determined by the replica technique, and the marginal gap was determined by microscopy. ANOVA was carried out to detect significant differences, and the Bonferron…
Non-alcoholic Fatty pancreas disease pathogenesis: a role for developmental programming and altered circadian rhythms.
2014
OBJECTIVES: Emerging evidence suggests that maternal obesity (MO) predisposes offspring to obesity and the recently described non-alcoholic fatty pancreas disease (NAFPD) but involved mechanisms remain unclear. Using a pathophysiologically relevant murine model, we here investigated a role for the biological clock - molecular core circadian genes (CCG) in the generation of NAFPD. DESIGN: Female C57BL6 mice were fed an obesogenic diet (OD) or standard chow (SC) for 6 weeks, prior to pregnancy and throughout gestation and lactation: resulting offspring were subsequently weaned onto either OD (Ob_Ob and Con_Ob) or standard chow (Ob_Con and Con_Con) for 6 months. Biochemical, pro-inflammatory a…
Zobārstu pilnā vainaga preparātu konverģences pārbaude Latvijā, laboratorijas pētījums
2020
Ievads: Vienas vienības kroņa vai fiksētas daļējas protēzes saglabāšana un pretestība ir divi mehāniski faktori, kas ir saistīti ar veiktās atjaunošanas prognozi. Publicētajā literatūrā tiek atbalstīti īpaši zoba sagatavošanas parametri kroņa uzlikšanai. Preparācijas vertikālajām sienām jābūt ar konverģences leņķi no 10-14 grādiem, lai nodrošinātu kroņa saglabāšanu. Šo parametru neievērošana rada lielāku risku zaudēt kroņa saglabāšanu. Tomēr pētījumi liecina, ka šie kritēriji parasti netiek ievēroti. Nespēja ierobežot vertikālās sienas konverģenci (kopējo okluzālo konverģenci) izraisa protēzes struktūras zudumu, kariesu, palielina zobu struktūras zūdumu preparēšanas laikā un samazinā zoba p…
Traditional Chinese herbal medicine at the forefront battle against COVID-19: Clinical experience and scientific basis.
2020
Abstract Background Throughout the 5000-year history of China, more than 300 epidemics were recorded. Traditional Chinese herbal medicine (TCM) has been used effectively to combat each of these epidemics’ infections, and saved many lives. To date, there are hundreds of herbal TCM formulae developed for the purpose of prevention and treatment during epidemic infections. When COVID-19 ravaged the Wuhan district in China in early January 2020, without a deep understanding about the nature of COVID-19, patients admitted to the TCM Hospital in Wuhan were immediately treated with TCM and reported later with >90% efficacy. Approach We conducted conduct a systematic survey of various TCM herbal pre…
