Effects of Access Cavity Design and Placement Techniques on Mineral Trioxide Aggregate Obturation Quality in Simulated Immature Teeth: A Micro-Computed Tomography Study.

In teeth with open apices, performing single session apexification is a challenging treatment due to the difficulty in handling mineral trioxide aggregate (MTA). Minimally invasive approaches in dentistry have also influenced the cavity designs in endodontics. Until now, different techniques have not been investigated in addition to manual condensation during the process of placing MTA in traditional (TradACs) or conservative (ConsACs) endodontic access cavities.

Efficiency of KTP laser for verrucae vulgaris and plantaris: A retrospective analysis.

Background: Verrucae are benign proliferations caused by human papillomavirus. Treatment is needed for pain, bleeding, contagiousness, and cosmetically.

Aims: The aim of this study is to evaluate the effectiveness of KTP laser treatment in verrucae, as well as side effects and recurrence rates.

Automated VMAT treatment planning using sequential convex programming: algorithm development and clinical implementation.

To develop and clinically implement a fully automated treatment planning system (TPS) for volumetric modulated arc therapy (VMAT).We solve two constrained optimization problems sequentially. The tumor coverage is maximized at the first step while respecting all maximum/mean dose clinical criteria.

In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No Concomitant Benefits: Experimental Evidence from 84 Countries.

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g.

Automated and Clinically Optimal Treatment Planning for Cancer Radiotherapy.

Each year, approximately 18 million new cancer cases are diagnosed worldwide, and about half must be treated with radiotherapy. A successful treatment requires treatment planning with the customization of penetrating radiation beams to sterilize cancerous cells without harming nearby normal organs and tissues. This process currently involves extensive manual tuning of parameters by an expert planner, making it a time-consuming and labor-intensive process, with quality and immediacy of critical care dependent on the planner's expertise.

Meaning in life, psychological hardiness and death anxiety: individuals with or without generalized anxiety disorder (GAD).

Generalized anxiety disorder (GAD) is a widespread psychiatric disorder. According to the transdiagnostic approach, death anxiety can underpin predominantly somatic manifestations of GAD. Personal resilience factors such as a sense of a meaningful life, and psychological hardiness, which can protect people from developing clinical symptoms, may be lower in individuals with GAD.

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation.

Internalized Stigma in Pediatric Psoriasis: A Comparative Multicenter Study.

Background: Internalized stigma, adoption of negative attitudes and stereotypes of the society regarding persons' illness, has not been studied previously in pediatric psoriasis patients.

Objective: We aimed to investigate the internalized stigma in pediatric psoriasis patients and to determine differences according to factors affecting internalized stigma compared to adult psoriasis patients.

Methods: This multicenter, cross-sectional, comparative study included 125 pediatric (55 female, 70 male; mean age±standard deviation [SD], 14.

Solving the volumetric modulated arc therapy (VMAT) problem using a sequential convex programming method.

The volumetric modulated arc therapy (VMAT) problem is highly non-convex and much more difficult than the fixed-field intensity modulated radiotherapy optimization problem. To solve it efficiently, we propose a sequential convex programming algorithm that solves a sequence of convex optimization problems. Beginning by optimizing the aperture weights of many (72) evenly distributed beams using the beam's eye view of the target from each direction as the initial aperture shape, the search space is constrained to allowing the leaves to move within a pre-defined step-size.

Posttraumatic Growth: A Comprehensive Evaluation of the Recently Revised Model.

For the last 30 years, the conceptualization studies of posttraumatic growth (PTG) which refer to the positive changes as a result of the struggle with adverse events, have been continuously evolving with new findings. In line with this empirical evidence, Tedeschi and colleagues have proposed a revised model in which PTG is accepted both as a process and an outcome. The roles of the concepts such as wisdom, resilience, socio-cultural factors are explained better.

A column generation heuristic for VMAT planning with adaptive CVaR constraints.

In this study we develop an efficient computational procedure that generates medically acceptable treatment plans for volumetric modulated arc therapy with constant gantry speed. Our proposed method is a column generation heuristic based on a mixed integer linear programming model, where the objective function contains minimization of total monitor unit of the treatment plan and dose-volume requirements are included as conditional value-at-risk constraints. Our heuristic generates a full treatment arc for the restricted master problem and calibrates the right hand side parameters of the conditional value-at-risk constraints in the first phase.

Data from the Human Penguin Project, a cross-national dataset testing social thermoregulation principles.

In the Human Penguin Project (N = 1755), 15 research groups from 12 countries collected body temperature, demographic variables, social network indices, seven widely-used psychological scales and two newly developed questionnaires (the Social Thermoregulation and Risk Avoidance Questionnaire (STRAQ-1) and the Kama Muta Frequency Scale (KAMF)). They were collected to investigate the relationship between environmental factors (e.g.

Meaning and Posttraumatic Growth Among Survivors of the September 2013 Colorado Floods.

In the wake of significant adversity, a range of recovery outcomes are possible, from prolonged distress to minimal effects on functioning and even psychological growth. Finding meaning in one's life is thought to facilitate optimal recovery from such adversity. Research on psychological growth and recovery often focuses on the daily hassles or significant traumas of convenience samples or on people's psychological recovery from medical illness.

The Relationship between ABO Blood Groups and Acne Vulgaris.

Background And Aim: Studies of associations between various cancers and the ABO blood groups have shown elevated relative risks for some categories of disease. There has so far been no report of an evaluation of the relationship between the ABO blood groups and acne vulgaris. To investigate this association, we conducted a retrospective study of acne vulgaris diagnosed in Turkey.
