Evaluation the level of vitamin D and its relationship with clinical symptoms in patients with COVID-19 referred to the medical center in Bam city.

Background: Vitamin D is a steroid hormone that protects against viral infections by influencing innate and adaptive immune responses. The effectiveness of vitamin D3 supplementation in COVID-19 is unknown. The study's goal was to elucidate the relationship between blood vitamin D levels and COVID-19 clinical outcomes by examining the effect of a single high dose of vitamin D3 on the length of hospital stay in COVID-19 patients.

Preparation of nanostructured photocatalyst ZnSnO@S-doped g-CN and its use in DB1 dye degradation through photocatalytic ozonation process.

This study aimed to investigate the potential of the photocatalytic ozonation process (PCO) for decolorizing DB1(direct blue) dye, a commonly used dye in the textile industry known for its resistance to removal from wastewater. To address this challenge, a ZnSnO@S-doped g-CN nano photocatalyst was synthesized using a simple hydrothermal method. In a novel approach, a light/O/ZnSnO@S-doped g-CN system was employed for the first time to degrade the DB1 dye.

Enhancing insecticidal efficacy of Bacillus thuringiensis Cry1Ab through pH-sensitive encapsulation.

Nanotechnology is a promising way to enhance the stability of Bacillus thuringiensis (Bt) insecticidal proteins under environmental conditions. In this work, two emulsions were prepared through the Pickering emulsion technique, stabilized by Cu-SQDs/S-CN nanocomposites and by GO nanosheets. In addition, a pH-sensitive polymer was incorporated into these emulsions, allowing the Bt protein, Cry1Ab, to be released in an alkaline pH environment, as it occurs in the lepidopteran pests' gut.

Green synthesis of bovine serum albumin/oxidized gum Arabic nanocomposite as pH-responsive carrier for controlled release of piperine and the molecular docking study.

A safe drug carrier was synthesized by albumin (BSA) and oxidized gum arabic (OGA). Piperine (PIP) was loaded into BSA/OGA nanobiocomposites by desolvation method. A set of experiments were designed by considering different contents of OGA (5, 7.

Effective visible-light-driven photocatalytic degradation of fenitrothion by s-gCN/Ag-Au bimetallic nanocomposite.

This paper reports on the optimization of fenitrothion photocatalytic degradation in visible light based on Plackett Burman (PB) design and central composite design (CCD) in response surface methodology (RSM). A herbicide routinely used with a negative impact on the environment is fenitrothion, which must be degraded to minimize the impact on the environment. For fenitrothion degradation, Ag-Au bimetallic nanoparticles on the semiconducting s-doped gCN surface were synthesized using the galvanic exchange.

Ultraviolet protection of Bacillus thuringiensis through microencapsulation with Pickering emulsion method.

An encapsulated formulation of Bacillus thuringiensis (Bt) was produced by the Pickering emulsion technique to improve its activity and stability under UV-A radiation. In this technique latex particles, GO nanosheets, olive oil, ethanol, and water were used to encapsulate Bt in colloidosomes. The protective efficacy of this formulation in protecting Bt subsp.

A novel method for biosynthesis of different polymorphs of TiO nanoparticles as a protector for Bacillus thuringiensis from Ultra Violet.

Bacillus thuringiensis (Bt) were used for biosynthesis of amorphous TiO converted to distinct polymorphs (anatase, rutile, mix) under different temperature conditions. Characterizations of TiO nanoparticles were performed by using X-ray diffraction spectroscopy (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and, energy-dispersive X-ray spectroscopy (EDX) analysis. Stability of five formulations under ultraviolet (UV) radiation with spore viability and mortality test on Ephestia kuehniella Zeller larvae were investigated.

Noble UV protective agent for Bacillus thuringiensis based on a combination of graphene oxide and olive oil.

The focus of this study is investigating the performance of graphene oxide (GO) in the protective effect of olive oil on Bacillus thuringiensis (Bt) after being exposed to UV radiations. Biological pesticides Bt subsp. Kurstaki is one of the most important biological control agents.
