Sports participation among adolescents is increasing, offering numerous health benefits and exposing them to the risk of sports-related injuries. This paper aims to understand that the prevalence and risk factors associated with these injuries are crucial for effective injury prevention and the overall well-being of adolescent athletes. This systematic review synthesizes the existing literature on sports-related injuries in adolescent athletes.

- - JE (Japanese Encephalitis) is a serious mosquito-borne viral infection that has a high fatality rate and can lead to severe neurological issues in survivors, with no known cures available.
- - The JE virus genome is relatively small (10.98 kb) and includes two coding regions and 15 peptides, with genomic analysis being conducted using 29 sequences from different countries and host animals to study its evolution.
- - The study found that a specific genome sequence from Taiwan had very few genetic variations compared to sequences from India, suggesting overall genetic similarity among JE virus strains.
Esculentosides include a group of plant-derived compounds with tremendous pharmacological potential. The antiproliferative effects of esculentoside A against different colorectal cancer cells were evaluated. We found that the proliferation of all the colorectal cancer cells was halted by esculentoside A.

Methods: The ceramic materials included IPS e.max CAD (lithium disilicate), VITA ENAMIC (polymer infiltrated ceramic), and Celtra Duo CAD (zirconia reinforced lithium silicate).
Efficacy of antimicrobial photodynamic therapy in disinfection of Candida biofilms on acrylic dentures: A systematic review.
Photodiagnosis Photodyn Ther
December 2022
Background: The aim of this systematic review was to critically analyze and summarize the currently available scientific evidence concerning antifungal efficacy of aPDT against Candida on acrylic surface.
Methods: The focused question was: '"Is aPDT effective in minimizing the counts of Candida on acrylic dentures". A literature search was conducted interpedently on the following electronic research databases: PubMED/MEDLINE, Cochrane, Google Scholar and Embase.
Objective: To compare the translucency and masking of zirconia-reinforced lithium silicate with lithium disilicate glass-ceramic and hybrid composite.
Materials And Methods: One hundred and twenty disc-shaped specimens were fabricated using Enamic, Celtra Duo, IPS E.max CAD, and Suprinity.
Objectives: Assessment of the effect of aging and bonding on the reparability of different temporary crown and bridge materials using a flowable resin composite.
Methods: The materials used included two bis-acryl and two polymethylmethacrylate materials. The materials were aged either dry, in distilled water, or in a 75% ethanol/water solution.
Background: To date, there has been no study identified that assessed peri-implant parameters and local levels of proinflammatory cytokines between waterpipe smokers (WS) and electronic cigarette users (VS). To evaluate the true effect of the risk indicator (WS and VS), a positive control (cigarette smokers [CS]) was added in the study design.
Purpose: To compare clinical and radiographic peri-implant parameters and proinflammatory cytokine profile in the peri-implant sulcular fluid (PISF) among CS, WS, VS, and nonsmokers (NS).
Objectives: The objectives of this study are to estimate the prevalence of self-medication with antibiotics in King Khalid University Hospital population and evaluate the factors affecting this behavior.
Materials And Methods: This was a cross-sectional study conducted at King Khalid university hospital from April to May 2016. A pretested self-administered questionnaire was handed to a random selection of 519 patients attending the primary care clinics .
Photodynamic therapy in the treatment of symptomatic oral lichen planus: A systematic review.
Photodermatol Photoimmunol Photomed
May 2018
Background: The aim of this systematic review was to assess the efficacy of photodynamic therapy (PDT) in the treatment of symptomatic oral lichen planus (OLP).
Methods: This systematic review aimed to address the following focused question: "Is PDT effective in the treatment of symptomatic OLP?" Indexed databases such as MEDLINE, EMBASE, and CENTRAL were searched up to and including August 2017.
Results: Six clinical studies were included.
Objectives: To evaluate the effect of silane application and silane heat treatment on lithium-disilicate ceramic when bonded to composite resin.
Methods: Twelve blocks of lithium-disilicate (LD) ceramic were fabricated and bonding surfaces were etched using 9.5% hydrofluoric acid (90 seconds).
Aims: This Study was conducted to determine the incidence of malocclusion, occlusal interferences, temporomandibular Disorder (TMD) among the Saudi population and to evaluate the possible existence of an association between malocclusion, occlusal interferences and TMD.
Methods: 250 patients attending dental clinics in Abha city, Saudi Arabia for treatment was clinically examined for the degree of malocclusion. Patients were further evaluated for the presence of occlusal interferences and TMD.
Objective: To report on the clinical presentation, etiology, and laboratory features of acute and chronic atrial fibrillation (AF) in a tertiary hospital in Riyadh, Saudi Arabia.
Materials And Methods: We retrospectively studied records of 720 patients with AF seen in outpatients and inpatients departments at King Abdulaziz Medical City, Riyadh, during the period of 1 January 2002 to 31 August 2008.
Results: Documented acute and chronic AF was present in 157 (21.
