Influence of a bioceramic root end material and mineral trioxide aggregates on fibroblasts and osteoblasts

2012

The biocompatibility of materials used in endodontic treatment is of high importance, because they can come in contact with periradicular tissues and there is a risk of possible systemic toxicity. The aim of the present study was to investigate the in vitro reaction to a bioceramic based root end material in comparison to mineral trioxide aggregates (MTA) as the established gold standard.The root end materials grey MTA Angelus (GMTA), white MTA Angelus (WMTA), ProRoot MTA, and EndoSequence Root Repair Material (ERRM) were incubated with human periodontal ligament fibroblasts and osteoblasts (10(4)cells/ml) for up to 96h. Cell proliferation (RFU) was determined by means of the Alamar Blue as…

Gaming Bot Detection: A Systematic Literature Review

2018

In online games, some players employ programs (bots) that allow them to bypass game routines and effortlessly gain virtual resources. This practice leads to negative effects, such as reduced revenue for the game development companies and unfair treatment for ordinary players. Bot detection methods act as a counter measure for such players. This paper presents a systematic literature review of bot detection in online games. We mainly focus on games that allow resource accumulation for players between game sessions. For this, we summarize the existing literature, list categories of games ignored by the scientific community, review publicly available datasets, present the taxonomy of detection…

Robust Allocation Rules in Dynamical Cooperative TU Games

2011

Robust dynamic coalitional TU games are repeated TU games where the values of the coalitions are unknown but bounded variables. We set up the game supposing that the Game Designer uses a vague measure of the extra reward that each coalition has received up to the current time to re-adjust the allocations among the players. As main result, we provide a constructive method for designing allocation rules that converge to the core of the average game. Both the set up and the solution approach also provide an insight on commonalities between coalitional games and stability theory.

Pre‐clinical evaluation of the effect of a volume‐stable collagen matrix on periodontal regeneration in two‐wall intrabony defects

2021

Aim To histologically evaluate the effect of a new collagen matrix on periodontal regeneration. Materials and methods Two-wall intrabony defects were surgically created bilaterally distally to the maxillary first and third pre-molars in beagle dogs. The defects were randomly allocated to open flap debridement either with (test) or without (control) a volume-stable collagen matrix (VCMX). After 12 weeks, the dogs were euthanized, and the specimens histologically processed. Descriptive, histomorphometrical (vertical gain of periodontal tissues) and statistical analyses were then performed. Results Healing was uneventful in most cases. Residual VCMX was still present and showed integration int…

Immunohistochemical Evaluation of Periodontal Regeneration Using a Porous Collagen Scaffold.

2021

(1) Aim: To immunohistochemically evaluate the effect of a volume-stable collagen scaffold (VCMX) on periodontal regeneration. (2) Methods: In eight beagle dogs, acute two-wall intrabony defects were treated with open flap debridement either with VCMX (test) or without (control). After 12 weeks, eight defects out of four animals were processed for paraffin histology and immunohistochemistry. (3) Results: All defects (four test + four control) revealed periodontal regeneration with cementum and bone formation. VCMX remnants were integrated in bone, periodontal ligament (PDL), and cementum. No differences in immunohistochemical labeling patterns were observed between test and control sites. N…

Similarities between Playing World of Warcraft and CLIL

2012

This article argues that playing World of Warcraft (WoW) and Content and Language Integrated Learning (CLIL) have a number of similar features. We base our argument on findings from three studies. The first (Sylvén 2004/2010) is about CLIL and non-CLIL students at upper secondary level and aims to investigate what effect, if any, CLIL has on the incidental acquisition of vocabulary. The second (Sundqvist 2009) is about extramural English and aims to examine its potential impact on learners’ oral proficiency and vocabulary. Extramural English is broadly defined as any type of contact that learners have with English outside the classroom. The third is a joint study focusing on young learners …

Abstract 13812: Pulmonary Function Predicts Cardiac Function, Structure & Clinical Outcome in Chronic Heart Failure: Results From the Myovasc Stu…

2020

Introduction: A growing body of evidence suggests a relevance of pulmonary function in the pathophysiology of heart failure (HF). Comprehensive data on the role of forced expiratory volume in 1 second (FEV1) in the development & progression of HF is limited. Hypothesis: Given this background, we hypothesized, that (FEV1) is associated with deteriorated left ventricular (LV) functional as well as structural status, & predicts specific clinical outcome in HF. Methods: Data from the MyoVasc Study (n=3,289) were analysed. Comprehensive clinical phenotyping including body plethysmography for the evaluation of FEV1 & standardized echocardiography were performed during a five-hour inv…

Cardinal inequalities involving the Hausdorff pseudocharacter

2023

We establish several bounds on the cardinality of a topological space involving the Hausdorff pseudocharacter $H\psi(X)$. This invariant has the property $\psi_c(X)\leq H\psi(X)\leq\chi(X)$ for a Hausdorff space $X$. We show the cardinality of a Hausdorff space $X$ is bounded by $2^{pwL_c(X)H\psi(X)}$, where $pwL_c(X)\leq L(X)$ and $pwL_c(X)\leq c(X)$. This generalizes results of Bella and Spadaro, as well as Hodel. We show additionally that if $X$ is a Hausdorff linearly Lindel\"of space such that $H\psi(X)=\omega$, then $|X|\le 2^\omega$, under the assumption that either $2^{<\mathfrak{c}}=\mathfrak{c}$ or $\mathfrak{c}<\aleph_\omega$. The following game-theoretic result is shown: i…
