Preparation and Evaluation of Phenol Formaldehyde-Montmorillonite and Its Utilization in the Adsorption of Lead Ions from Aqueous Solution.

In this study, phenol formaldehyde-montmorillonite (PF-MMT) was prepared and used for lead ion (Pb) adsorption. Batch adsorption experiments were conducted to determine the optimal conditions. The calculated adsorption equilibrium () revealed that pseudo-second-order (PSO) and Langmuir isotherm models best fit the experimental data, suggesting chemisorption as the main mechanism.

Comparison of the Efficacy and Safety of Left Atrial Appendage Closure and Direct Oral Anticoagulants for Atrial Fibrillation: A Meta-Analysis of Randomized Control Trials and Observational Studies.

The aim of this study was to compare the efficacy and safety of left atrial appendage closure (LAAC) and direct oral anticoagulants (DOACs) in patients with atrial fibrillation (AF). This meta-analysis was conducted as per the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. Two investigators performed an online database search on PubMed, Web of Science, and Scopus databases from inception to October 31, 2023, without any language or time restrictions.

Decision-Making Preferences among Advanced Cancer Patients in a Palliative Setting in Jordan.

Understanding patients' decision-making preferences is crucial for enhancing patients' outcomes. The current study aims to identify Jordanian advanced cancer patients' preferred decision-making and to explore the associated variables of the passive decision-making preference. We used a cross-sectional survey design.

Validation of the Arabic Version of the Edmonton Symptom Assessment System.

Quality cancer care is a team effort. In addition, patients' symptoms change over the course of treatment. As such, the Edmonton Symptom Assessment System (ESAS) is a simple tool designed to quickly monitor symptom change.

Three-dimensional evaluation of root canal morphology of maxillary first premolars: Micro-computed tomographic study.

Aim: The aim of this study was to investigate the root and root canal morphology of maxillary first premolar teeth in a Kuwaiti population using micro-computed tomography (μ- CT).

Materials And Methods: A total of 100 maxillary first premolars were scanned in a micro- computed tomographic device. The external anatomy (number of roots, distance from cementoenamel junction to apex, and presence of a palatal groove) and internal anatomy (number of canals and presence of apical deltas, lateral canals, and isthmi) of teeth were analyzed using descriptive analysis.

Exploring the Nexus Between E-Business Processes and Organizational Performance: Can Technological Opportunism Play Any Role?

The digitization of business processes has gained much scholarly and practical attention in the recent past. To understand their effectiveness, particularly in connection to organizational performance, the current study developed and tested a comprehensive framework. Through obtaining data from 350 manufacturing businesses, the study investigated using Smart PLS3 and found a significant influence of online procurement, channel management, and service delivery capabilities on organizational performance.

A Digital Microscopic Inspection of Dentinal Defects after Using Endodontic Retreatment Files.

Aim: The study aimed at evaluating the incidence of dentinal defects after root canal retreatment with ProTaper Universal retreatment (PTUR) and XP-endo Shaper and Finisher R (XP).

Materials And Methods: Sixty extracted single-rooted human premolars were selected and divided into 4 groups of 15 teeth each. In the negative control group, the teeth were left unprepared.

The effect of dental restoration type and material on periodontal health.

Purpose: To investigate the relationship between the type and material of dental restorations and periodontal health in a sample of Jordanians.

Materials And Methods: Patients attending the Dental Teaching Clinics of Jordan University of Science and Technology with restored teeth were examined. For every patient, the plaque index, gingival index, probing depth and clinical attachment level were recorded on restored and non-restored tooth surfaces.

Frequency and distribution of root filled teeth and apical periodontitis in a Jordanian subpopulation.

Objective: The aim of this study was to evaluate the prevalence and distribution of apical periodontitis and endodontic treatment in a Jordanian subpopulation.

Study Design: Digital panoramic radiographs of 294 patients who were assessed at Caritas Association between January and September 2008 were evaluated. The coronal and periapical status of all visible teeth were evaluated according to the criteria proposed by de Moor et al.

The radiographic outcomes of direct pulp-capping procedures performed by dental students: a retrospective study.

Background: The decision between pulp capping and root canal therapy after pulp exposure is a clinical issue. The aim of the authors' study was to evaluate the outcome of direct pulp-capping procedures performed by dental students.

Methods: The authors followed the treatment outcomes of 193 patients with 204 pulp exposures with direct pulp capping.

Compliance with infection control programs in private dental clinics in Jordan.

Rapid response to rituximab in a pediatric liver transplant recipient with post-transplant lymphoproliferative disease and maintenance with sirolimus monotherapy.

A 12-yr-old girl with end-stage renal disease secondary to primary hyperoxaluria type I received a living related (left lateral segment) liver transplant from her brother as the first step of a staged liver and kidney transplant. Renal transplantation was planned for a later date from the same donor. Nine weeks after transplantation she developed polymorphic PTLD of the tonsils and adenoids.
