A study of chloride binding capacity of concrete containing supplementary cementitious materials.

Chloride-induced steel corrosion is known to be a very common kind of deterioration of reinforced concrete. It is beneficial to bind free chloride ions to reduce the corrosion probability of the reinforcement embedded in the concrete. The binding capacity of the concrete varies according to its cementitious system.

Effect of surface morphology on optical properties of two multilayer structures CuO/ZnO/SiC and AlO/ZnO/SiC.

Zinc oxide (ZnO) and Silicon carbide (SiC) thin films demonstrate unique properties such as high electron mobility, thermal stability, good chemical resistance, and low cost made them good candidates for optical applications. Moreover, semiconductors absorb short wavelengths of light due to the presence of a band gap. This work's purpose is to study the effect of deposited ZnO and SiC thin films by physical vapor deposition (PVD) above two different oxides and substrates.

The Beneficial Effects of Emotional Intelligence Training for Critical Care Nurses on Job Burnout: A Quasi-Experimental Study.

Background: Critical care nurses are at especially high risk of burnout. Burnout is a maladaptive response to work-related stress that is associated with negative consequences for patients. Emotional intelligence enables nurses to make better decisions and manage their patients more effectively.

Diagnosing the culprit behind a subtle case of concomitant right atrial myxoma and atrial fibrillation: A case report.

Myxomas are rare tumors arising from the uncontrolled proliferation of mesenchymal cells. Among cardiac conditions, cardiac myxomas account for less than 0.1% of cases, with the majority found in the left atrium and only 8% in the right atrium.

Exploiting fungi in bioremediation for cleaning-up emerging pollutants in aquatic ecosystems.

Aquatic pollution negatively affects water bodies, marine ecosystems, public health, and economy. Restoration of contaminated habitats has attracted global interest since protecting the health of marine ecosystems is crucial. Bioremediation is a cost-effective and eco-friendly way of transforming hazardous, resistant contaminants into environmentally benign products using diverse biological treatments.

A comprehensive review on sustainable clay-based geopolymers for wastewater treatment: circular economy and future outlook.

In the present era of significant industrial development, the presence and dispersal of countless water contaminants in water bodies worldwide have rendered them unsuitable for various forms of life. Recently, the awareness of environmental sustainability for wastewater treatment has increased rapidly in quest of meeting the global water demand. Despite numerous conventional adsorbents on deck, exploring low-cost and efficient adsorbents is interesting.

Objective: To evaluate the protective role of nanocurcumin on the toxicity induced by methotrexate in the submandibular glands of rats.

Design: Twenty- four healthy male Wistar albino rats were randomly distributed into 3 groups, 8 rats each. Group I-control: rats received a single intraperitoneal injection of saline; Group II-methotrexate (MTX): rats received methotrexate 20 mg/ kg day 1 of the experiment; Group III-methotrexate and nanocurcumin (MTX+NCU): rats received methotrexate 20 mg/ kg on day 1 of the experimental period in addition to nanocurcumin 100 mg/kg/day for 7 days.

Expression of leptin receptor in renal tubules is sparse but implicated in leptin-dependent kidney gene expression and function.

Leptin regulates energy balance via leptin receptors expressed in central and peripheral tissues, but little is known about leptin-sensitive kidney genes and the role of the tubular leptin receptor (Lepr) in response to a high-fat diet (HFD). Quantitative RT-PCR analysis of Lepr splice variants A, B, and C revealed a ratio of ∼100:10:1 in the mouse kidney cortex and medulla, with medullary levels being ∼10 times higher. Leptin replacement in / mice for 6 days reduced hyperphagia, hyperglycemia, and albuminuria, associated with normalization of kidney mRNA expression of molecular markers of glycolysis, gluconeogenesis, amino acid synthesis, and megalin.

Cinnamon Oil Encapsulated with Silica Nanoparticles: Chemical Characterization and Evaluation of Insecticidal Activity Against the Rice Moth, Corcyra cephalonica.

Cinnamon (Cinnamomum zeylanicum Blume) essential oil has vast potential as an antimicrobial but is limited by its volatility and rapid degradation. To decrease its volatility and prolong the efficacy of the biocide, cinnamon essential oil was encapsulated into mesoporous silica nanoparticles (MSNs). The characterization of MSNs and cinnamon oil encapsulated with silica nanoparticles (CESNs) was estimated.

Self-Assessed Capabilities, Attitudes, and Stress among Pediatric Nurses in Relation to Cardiopulmonary Resuscitation.

Background: In emergency medicine, cardiopulmonary resuscitation (CPR) is one of the most stressful scenarios for nurses who conduct both basic and advanced resuscitation methods.

Aim: This study aimed to assess nurses' self-assessed capabilities, attitudes, and stress related to CPR.

Methods: This cross-sectional, observational study was carried out on 748 pediatric nurses at six governmental hospitals.

Characterization and Biodegradation of Phenol by and Strains Isolated from Sewage Sludge and Their Effect on Soybean Seeds Germination.

Phenols are very soluble in water; as a result, they can pollute a massive volume of fresh water, wastewater, groundwater, oceans, and soil, negatively affecting plant germination and animal and human health. For the detoxification and bioremediation of phenol in wastewater, phenol biodegradation using novel bacteria isolated from sewage sludge was investigated. Twenty samples from sewage sludge (SS) were collected, and bacteria in SS contents were cultured in the mineral salt agar (MSA) containing phenol (500 mg/L).

Autogenous dentin graft versus alloplastic graft combined with socket shield for pre-implant socket preservation: a split-mouth randomized clinical trial.

After tooth extraction, alveolar bone resorption and labial bone plate thinning occur due to the lack of periodontal ligaments. The socket shield method was developed to preserve the alveolar ridge. A split-mouth study was performed in which eight patients were treated using alloplast with socket shield on one side (alloplast group, control) and autogenous dentin graft with socket shield on the contralateral side (dentin group, test).

Stapler Assisted Total Laryngectomy: A Prospective Randomized Clinical Study.

Closure of the pharyngeal defect after total laryngectomy had been traditionally performed with manual suturing techniques that invert the mucosal edge this technique though effective, yet it is time-consuming. Recently the use of stapling devices to successfully close the pharyngeal defect after total laryngectomy has been advocated to shorten the operative time, especially in the high-risk cancer patients where a prolonged operative time is not preferred. The present study aimed at comparing stapler assisted total laryngectomy to suture closure total laryngectomy in a prospective randomized manner.

The Effect of Coenzyme Q10/Collagen Hydrogel on Bone Regeneration in Extraction Socket Prior to Implant Placement in Type II Diabetic Patients: A Randomized Controlled Clinical Trial.

Background: The healing of an extraction socket leads to alveolar ridge resorption that can hinder future implant placement and further rehabilitation with special concerns in diabetes mellitus. Coenzyme Q10 (CoQ10) has been developed as a new material for alveolar socket augmentation. The aim of this study was to investigate the effect of CoQ10 hydrogel on bone regeneration after extraction of mandibular teeth in Type II diabetic patients.

High levels of dd-cfDNA identify patients with TCMR 1A and borderline allograft rejection at elevated risk of graft injury.

The clinical importance of subclinical, early T cell-mediated rejection (Banff TCMR 1A and borderline lesions) remains unclear, due, in part to the fact that histologic lesions used to characterize early TCMR can be nonspecific. Donor-derived cell-free DNA (dd-cfDNA) is an important molecular marker of active graft injury. Over a study period from June 2017 to May 2019, we assessed clinical outcomes in 79 patients diagnosed with TCMR 1A/borderline rejection across 11 US centers with a simultaneous measurement of dd-cfDNA.
