Efficient green Cr(VI) adsorbent from sorghum waste: Eco-designed functionalized mesoporous silica FDU-12.

This paper presents an eco-design approach to the synthesis of a highly efficient Cr(VI) adsorbent, utilizing a positively charged surface mesoporous FDU-12 material (designated as MI-Cl-FDU-12) for the first time. The MI-Cl-FDU-12 anion-exchange adsorbent was synthesized via a facile one-pot synthesis approach using sodium silicate extracted from sorghum waste as a green silica source, 1-methyl-3-(triethoxysilylpropyl) imidazolium chloride as a functionalization agent, triblock copolymer F127 as a templating or pore-directing agent, trimethyl benzene as a swelling agent, KCl as an additive, and water as a solvent. The synthesis method offers a sustainable and environmentally friendly approach to the production of a so-called "green" adsorbent with a bimodal micro-/mesoporous structure and a high surface area comparable with the previous reports regarding FDU-12 synthesis.

Effect of Shields in Radiation Dose and Secondary Biological Risk of Gonads in Lumbosacral Digital and Computerized Radiography.

Background: The purpose of this study was to evaluate the effect of shields in imposed radiation dose to gonads in anterior-posterior (AP) and lateral views of lumbosacral radiography using digital radiography (DR) and computerized radiography (CR) methods.

Materials And Methods: Sixty patients who were suspected to AP and lateral view of lumbosacral radiography were included in this study. The patients were exposed with and without shields which have 0.

Photographic Evaluation of Burn Depth via Telemedicine: Insights from Iranian Surgeons.

Background: The accurate assessment of burn depth is crucial for determining appropriate treatment. Telemedicine has emerged as a promising tool for supporting burn diagnosis and decision-making, as it allows for remote consultation with burn specialists and access to high-quality imaging. The aim of this study was to evaluate the diagnostic capabilities of telemedicine in diagnosing burn depth.

Motivations for alcohol consumption during the COVID-19 pandemic in Islamic Republic of Iran.

Background: High alcohol consumption is an important public health problem, and understanding factors associated with such consumption is essential.

Aims: This study aimed to assess individual and social factors associated with alcohol consumption during the coronavirus disease 2019 (COVID-19) pandemic in the Islamic Republic of Iran.

Methods: In this qualitative study, purposive sampling was used to select study participants by sharing the survey link on the Telegram application channels with an Iranian audience during COVID-19.

Orofacial Pathological Lesions in Children and Adolescents: A 25-year survey in Iran.

Statement Of The Problem: Oral pathological conditions presented in children are various and often different from those of adults. There is considerable variation in the prevalence of these lesions among different regions of the world.

Purpose: The aim of this study was to assess the frequency and clinical-pathological features of oral lesions diagnosed in children and adolescents throughout 25 years in an oral pathology department.

Influence of Root Canal Curvature on the Accuracy of Root ZX Electronic Foramen Locator: An Study.

Introduction: The aim of this study was to evaluate the correlation between accuracy of Root ZX electronic foramen locator and root canal curvature.

Methods And Materials: One hundred and ten extracted mandibular molars were selected. Access cavity was prepared and coronal enlargement of mesiobuccal canal was performed.

Comparison of the effects of Crataegus oxyacantha extract, aerobic exercise and their combination on the serum levels of ICAM-1 and E-Selectin in patients with stable angina pectoris.

Background: Adhesion molecules play an important role in the development and progression of coronary atherosclerosis. The aim of this study was comparing the effect of Cratagol herbal tablet, aerobic exercise and their combination on the serum levels of Intercellular adhesion molecule (ICAM)-1 and E-Selectin in patients with stable angina pectoris.

Methods: Eighty stable angina pectoris patients aged between 45 and 65 years, were randomly divided into four groups including three experimental groups and one control group: aerobic exercise (E), Crataegus oxyacantha extract (S), aerobic exercise and Crataegus oxyacantha extract (S+E), and control (C).

Median and ulnar nerve injuries; what causes different repair outcomes?

Background: Peripheral nerve injuries have significant effects on patients' life quality. To make patients' therapeutic expectations more realistic, prediction of repair outcome has significant importance.

Materials And Methods: Totally, 74 patients with 94 nerve injuries (44 median and 50 ulnar nerves) were evaluated and followed up for 5 years between 2008 and 2013 in two main university hospitals of Isfahan.

Evaluation of craniofacial proportions: A pilot study.

Background: Regarding the need for determining the cephalometric norms for each population and the advantages of proportional analyses, we evaluated the variables of McNamara and Schwartz analyses and their relation in a pilot study on 6-17 years old Iranian students and provided formulas, which show these relations.

Materials And Methods: In this descriptive-analytical study, a tatal of cephalometric radiographs from the archive documents of Orthodontic Department of Isfahan Dental School was selected and traced. The variables of McNamara and Schwartz analyses were investigated.

Stability of antibacterial activity of Chlorhexidine and Doxycycline in bovine root dentine.

Objective: The aim of this study was to compare the substantivity of chlorhexidine (CHX) and doxycycline bond to the dentin in diffusion disk method.

Methods: A total of 92 dentin disks were prepared from Bovine's teeth root. After removing cementum and standardizing disks in weight and outer diameter, they were irrigated with sodium hypochlorite 2.

The effect of three irrigants on the coronal leakage of the root canals system irrigants.

Introduction: The production of smear layer during canal instrumentation is thought to increase coronal microleakage even after canal obturation. Previous studies have shown that the type of irrigant does not necessarily affect the seal of the obturation. Our study aimed to evaluate the effect of three irrigation solutions (MTAD, citric acid and EDTA/NaOCl) on the coronal microleakage of root canals.
