Manganese recovery from electric arc furnace dust bioleachate: Evaluation of different precipitation agents.

This study optimized a one-step precipitation process for manganese recovery from a complex medium-bioleachate obtained from electric arc furnace dust (EAFD). The effects of pH variations and different precipitation agents, including acetone, ethanol, oxalic acid, and ammonium hydroxide, were investigated for manganese recovery. While acetone and ethanol facilitated precipitation, they did not lead to the formation of a specific manganese precipitate.

Comprehensive Iranian guidelines for the diagnosis and management of maple syrup urine disease: an evidence- and consensus- based approach.

Maple Syrup Urine Disease (MSUD) disease is a defect in the function of the Branched-chain 2-ketoacid dehydrogenase complex (BCKDH). It is caused by pathogenic biallelic variants in BCKDHA, BCKA decarboxylase, or dihydrolipoamide dehydrogenase. The brain is the major organ involved in MSUD.

Determining and comparing the achieved competencies of graduating nursing students of public and private universities in Iran.

Aim: This study aims to determine and compare the achieved competencies of graduating nursing students of public and private universities in Iran.

Background: The main responsibility of nursing education is to train nurses who possess the necessary competencies to provide safe and high-quality care. Given that a significant proportion of nursing education in Iran is the responsibility of private universities, it is essential to ensure that nursing graduates acquire the required competencies.

Effect of atorvastatin gel in non-surgical treatment of peri-implant mucositis: A randomized controlled clinical trial.

Background: Peri-implant diseases, such as peri-implant mucositis and peri-implantitis, are inflammatory conditions caused by biofilms that can lead to the loss of surrounding soft tissues and bone. The most effective treatment involves non-surgical mechanical debridement to remove plaque, but other treatment modalities have shown limited success. This study investigated the anti-inflammatory and immunomodulatory effects of atorvastatin (ATV) gel as an additional treatment for peri-implant mucositis.

Efficient visible-light-driven photocatalytic degradation of antibiotics in water by MXene-derived TiO-supported SiO/TiC composites: Optimisation, mechanism and toxicity evaluation.

Photocatalytic technology has emerged as a promising solution to global water contamination, mainly through the effective degradation of persistent pharmaceutical pollutants. However, a few challenges still exist in enhancing degradation efficiency, reducing the toxicity of by-products, and ensuring cost-effective scalability. This study focuses on Tetracycline Hydrochloride (TCH) as an index antibiotic pollutant to evaluate the performance of a novel MXene-derived TiO-supported SiO₂/TiC composite (SMXT) synthesized using ultrasonic and wet impregnation techniques.
