Wastewater treatment using nanodiamond and related materials.

Nanodiamonds (NDs) are zero-dimensional (0D) carbon-based nanoparticles with SP/SP-hybridized carbon atoms that have shown great potential in wastewater treatment areas due to their high surface area, chemical stability, and unique adsorption properties. They can efficiently remove a wide range of pollutants from water, including heavy metals, organic compounds, and dyes via various mechanisms such as electrostatic interactions, π-π stacking, and ion exchange. NDs can be functionalized following different surface chemistries, enabling tailored surface properties and enhanced pollutant adsorption capabilities.

Green Synthesis of Cerium-Based Metal-Organic Framework (Ce-UiO-66 MOF) for Wastewater Treatment.

Green synthesis of metal-organic frameworks (MOFs) in aqueous solutions under ambient conditions with reduced production costs and environmental effects is an efficient technique to transfer lab-scale production to industrial large scale. Hence, this work proposes a green, low-cost, sustainable, rapid, and innovative synthetic strategy to produce cerium-based (Ce-UiO-66) MOFs under ambient conditions in the presence of water as a green solvent. This synthetic strategy exhibits great potential compared to conventional solvothermal synthetic techniques, and it does not need external activation energy and organic solvents, which can achieve the standards of green chemistry.

Three-dimensional opto-thermo-mechanical model for predicting photo-thermal optical coherence tomography responses in multilayer geometries.

Photothermal optical coherence tomography (PT-OCT) is a functional extension of OCT with the ability to generate qualitative maps of molecular absorptions co-registered with the micron-resolution structural tomograms of OCT. Obtaining refined insight into chemical information from PT-OCT images, however, requires solid understanding of the multifactorial physics behind generation of PT-OCT signals and their dependence on system and sample parameters. Such understanding is needed to decouple the various physical effects involved in the PT-OCT signal to obtain more accurate insight into sample composition.

Transient-mode photothermal optical coherence tomography.

Photothermal optical coherence tomography (PT-OCT) is an emerging extension of OCT, which forms images based on both scattering and absorption of light. The speed of PT-OCT, however, has been limited by the necessity for lock-in detection with extensive temporal sampling of the sample's PT response. Here, we demonstrate transient-mode PT-OCT (TM-PT-OCT), which increases the effective A-line rate by orders of magnitude from 10-100 Hz to 1.

Systematic review of productivity loss among healthcare workers due to Covid-19.

Objective: To assess existing evidence on the effects of COVID-19 on healthcare workers (HCWs) using the health-related productivity loss approach.

Methods: A systematic search of online databases including PubMed, Scopus, Ovid, Web of Science, and EMBASE was conducted up to 25 August 2020. Following two screening stages, studies related to the effects of COVID-19 on healthcare workers were included in the study.

Caustic ingestion in children in south of Iran. Retrospective study from Shiraz - Iran.

Unlabelled: Caustic ingestion is a major health concern in both developed and developing countries, that may lead to serious esophageal injury. The clinical presentation of caustic ingestion in children vary from asymptomatic to serious and fatal sequelae, such as perforation and stricture formation.

Objective: Due to the lack of a comprehensive study in our area, this study has evaluated clinical and endoscopic manifestations and complications of caustic ingestion in children in south of Iran.

Distribution of hospital beds in Tehran Province based on Gini coefficient and Lorenz curve from 2010 to 2012.

Introduction: Fair distribution of hospital beds across various regions is a controversial subject. Resource allocation in health systems rarely has focused on those who need it most and, in addition, is often influenced by political interests. The study assesses the distribution of hospital beds in different regions in Tehran, Iran, during 2010-2012.

The relationship between learning style preferences and gender, educational major and status in first year medical students: a survey study from iran.

Background: Identifying and employing appropriate learning styles could play an important role in selecting teaching styles in order to improve education.

Objectives: This study aimed to determine the relationship between learning styles preferences and gender, educational major and status in first year students at Isfahan University of Medical Sciences.

Patients And Methods: A cross-sectional study employing the visual-aural-read/write-kinesthetic (VARK) learning style's questionnaire was done on 184 first year students of medicine, pharmacy, dentistry, nursing and health services management at Isfahan University of Medical Sciences in 2012.

Discharge against medical advice: a case study in a public teaching hospital in Tehran, Iran in 2012.

 Discharging against medical advice is to leave the hospital despite the advice of the doctor, which can result in complications and readmissions. This study aimed to examine the prevalence of patients' discharge against medical advice (DAMA) and their reasons in a public teaching hospital in Tehran, Iran in 2012. This was an applied and cross-sectional study in which all patients (2601 patients) who had been discharged against medical advice from the studied hospital in 2012 were studied.

Estimation of nursing staff in selected hospitals of ilam and ahvaz provinces, Western iran.

Background: The nurses as the largest group among different groups of hospital workforce play a crucial role in success of the hospital activities and promotion of community health.

Objectives: This study aimed to obtain an estimation of the necessary nursing workforce status in educational hospitals affiliated to Ilam and Ahvaz University of Medical Sciences based on the scientific formula.

Materials And Methods: This research was a cross sectional-descriptive study, which was done in hospitals affiliated to Ilam and Ahvaz University of Medical Sciences during 2010.

Application of WHO model for evaluating Patient Safety Friendly Hospital Initiatives (PSFHI) in an Eye hospital in Tehran, Iran.

Background: Patient safety is one of the major issues concerning the medical community and the World Health Organization (WHO) in most countries. This study aimed to evaluate the patient safety status in an Eye Hospital in Tehran, using the WHO model for Patient Safety Friendly Hospital Initiatives (PSFHI) in 2012.

Methods: This Cross-Sectional study was done in an Eye Hospital in Tehran.

Acute glomerulonephritis: a 7 years follow up of children in center of Iran.

Acute glomerulonephritis (AGN) is a type of renal disease which indicates the inflammation of glomerulus and nephrons. This study was carried on 94 children, <15 years old with the diagnosis of AGN who were admitted to Qom and Yazd's hospitals between 2000 and 2006. Data were collected using hospital records on admission, progression notes and outpatient follow up.
