Introduction: The protein has been observed to exhibit an association with various autoimmune conditions, including psoriasis and rheumatoid arthritis. Genetic experiments have revealed that changes in Zinc finger protein-coding sequences correlate with an increased vulnerability to developing autoimmune diseases, so we aimed to study investigates the involvement of rs10947540 and rs1888822 gene expression in individuals diagnosed with Rheumatoid Arthritis.
Methods: In a case-control study conducted from January 2022 to March 2023, 80 adults with RA from Menoufia University Hospital were compared with 80 age- and gender-matched healthy controls.
Background: We tested the hypothesis that nebulized budesonide would improve lung mechanics and oxygenation in patients with early acute lung injury (ALI) and/or acute respiratory distress syndrome (ARDS) during protective mechanical ventilation strategy without adversely affecting systemic hemodynamics.
Methods: Patients with ALI/ARDS were included and assigned into two groups; budesonide group (30 cases) in whom 1 mg-2 ml budesonide suspension was nebulized through the endotracheal tube and control group (30 cases) in whom 2 ml saline (placebo) were nebulized instead of budesonide. This regimen was repeated every 12 h for three successive days alongside with constant ventilator settings in both groups.
Periodontitis is a progressive disease of the periodontium with a complex, polymicrobial etiology. Recent Next-Generation Sequencing (NGS) studies of the microbial diversity associated with periodontitis have revealed strong, community-level differences in bacterial assemblages associated with healthy or diseased periodontal sites. In this study, we used NGS approaches to characterize changes in periodontal pocket bacterial diversity after standard periodontal treatment.

Participants And Methods: Comparative prospective study was conducted among a total of 72 pregnant women at 28-38 weeks of gestation. They were divided into two groups (control and study) according to the absence or presence of clinical parameters of preeclampsia.
Introduction: Symptomatic teeth with periradicular lesions of infectious origin remain a significant challenge in dentistry, and the reason for the acute perturbation is incompletely understood. The present study used pyrosequencing of bacterial 16S ribosomal RNA (rRNA) genes to characterize the microbiota of periradicular lesions.
Methods: Thirteen periradicular lesions from 11 symptomatic and 2 asymptomatic teeth were sampled during apical surgery.
Objective: The aim of the study was to evaluate the efficacy of the microtensile bond test (microTBS) and the microshear bond test (microSBS) in ranking four dental adhesives according to bond strength to enamel and identify the modes of failure involved.
Materials And Methods: Forty-four caries-free human molars were randomly assigned to one of two bond strength testing methods: 20 teeth were used for microTBS test and 24 teeth for microSBS test. Flat enamel surfaces were created by wet grinding.
Objective: The objective of the current study was to compare in-vitro the proximal contact tightness (PCT) of Class II resin composite restorations (RCR) placed with different established and new placement techniques.
Methods: 105 ivorine lower left first molars with standardized MO cavities were randomly divided into seven groups (n = 15) as follows: SRing: sectional matrix and separation ring (Garrison Dental); CRing: circumferential matrix (1101-c, KerrHawe SA) with separation ring; CWedge: circumferential matrix with a wedge only; COptra: circumferential matrix and OptraContact (Vivadent); CCerana: circumferential matrix and a Cerana insert (Nordiska Dental); CElliot: circumferential matrix and Elliot separator (PFINGST & Co) and Walser: Walser matrix O-type (Dr Walser Dental GmbH). In all the groups, the matrix band was secured using a wooden wedge except for the Walser group, following manufacturer's recommendations.
