Background: The association between hepatitis C virus (HCV) infection and oral lichen planus (OLP), an extrahepatic manifestation, is well known. There are still patients with viral liver disease in this country who are not receiving appropriate treatment. This prospective study aimed to evaluate the prevalence of OLP and untreated hepatitis virus infection in patients who visited dental clinics in Ehime prefecture, in western Japan. Methods: Patients who visited 35 dental clinics in Japan from March 2018 to June 2 [...]

The present study investigates the association between anger, stress, psychological distress and mood disorders among Egyptian entrepreneurs. Approach-wise, the study is quantitative, and its cross-sectional data were collected using a questionnaire. The study’s respondents are Egyptian entrepreneurs involved in several business activities. Hence, the study concluded based on 286 valid responses. We used analysis of moment structures (AMOS) software, where we conducted path analysis to conclude the results. C [...]

Children's leisure time in the Western world is changing compared to what it used to be in the previous decades. Children's involvement in organized activities and screen time use is increasing, while outdoor play, despite once being the main leisure time activity for children, is declining. Gray, Oliver and other contemporary theorists link this shift in children's lifestyles to an increase in the prevalence of anxiety disorders. This study aimed to determine whether allocating preschool children's [...]

We address the Wind Farm Layout Optimization (WFLO) problem and tackle the optimal placement of several turbines within a specific (wind farm) area by incorporating additional aspects of an economically driven target function. With this, we contribute three refinements for WFLO research: First, while many research contributions optimize the turbines' locations subject to maximum energy production or energy efficiency, we instead pursue a strategy of maximizing a profit objective. This enables us to incorporate inne [...]

TiO2 photocatalyst was prepared using cellulase as a biotemplate through a hydrothermal process. The as-prepared catalyst was characterized based on physicochemical techniques and was used to remove As(III) from contaminated water. The cellulase templated TiO2 photocatalyst (TiO2-cellulase) had a large specific surface area, which reached 166.6 m2·g–1. It also had a strong oxidation ability and, thus, behaved well in both photocatalytic oxidation of As(III) and dark adsorption. The pH of the solution h [...]

This citizen science project CLUE compared the attack frequency between school and vacation periods among adolescents. The data collection process adopted in citizen science projects opens up the possibility of conducting analyses by including a large number of participants over a long period and across different regions. The data on 684 migraine attacks reported by 68 adolescents aged 16 to 19 years were collected using an online platform and smartphone apps. A Fisher’s exact test was used to compare the distribut [...]

The objective of the present experimental study was to compare how young people, healthy older people, and older people with dementia cognitively integrated three factors (Intention, Consequence, and Apology) when making blame-like judgments (prosecution and revenge) and forgiveness-like judgments (resentment and reconciliation). Thirty-four young people (Mage = 22.12, SD = 3.44), 22 healthy older people (Mage = 71.82, SD = 8.69), and 18 older people with dementia (Mage = 75, SD = 10.06) participated in the study. [...]

Water scarcity is one of the most pressing global challenges, particularly in arid and semi-arid regions. In this context, the Gaza Strip, where groundwater is the only available natural water resource, faces severe water stress due to overexploitation and drought conditions. This study aimed to review the recent water budget for the Gaza Strip by collecting data for the years (2021-2022) which was analyzed, discussed, and compared with other studies. The results showed a sharp deterioration in the Gaza Strip in te [...]

Layered double hydroxides (LDHs) have interesting properties and structures that enable them to carry nucleic acids, such as deoxyribonucleic acid (DNA). This study synthesized LDHs using the co-precipitation method and functionalized with the amino acids arginine (Arg) and histidine (His) to promote proton-sponge activity for enhanced transgene expression. The LDHs were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), and nanoparticle tracking analysis (NTA). The interaction of [...]
