Their chemical structures were elucidated by using IR, ECD, HR-ESI-MS, 1D and 2D NMR methods.

Cotreatment strategy for hazardous arsenic-calcium residue and siderite tailings via arsenic fixation as scorodite.

Siderite tailings is a potentially cost-free iron (Fe) source for arsenic (As) fixation in hazardous arsenic-calcium residues (ACR) as stable scorodite. In this study, a pure siderite reagent was employed to investigate the mechanism and optimal conditions for As fixation in ACR via scorodite formation, while the waste siderite tailings were used to further demonstrate the cotreatment method. The cotreatment method starts with an introduction of sulfuric acid to the ACR for As extraction and gypsum precipitation, and is followed by the addition of HO to oxidize As(III) in the extraction solutions and finalized by adding siderite with continuous air injection for scorodite formation.

Effect of polymer architecture on the properties and in vitro cytotoxicity of drug formulation: A case study with mono- and di-gradient amphiphilic poly(2-Oxazoline)s.

Due to the straightforward single-step synthesis, amphiphilic gradient copoly(2-oxazoline)s are becoming more popular alternative to their block analogue for the development of next-generation drug delivery systems. Here, we investigated the influence of polymer architecture on the physiochemical and biological assessment of nanoformulations formed by the self-assembly of gradient copoly(2-oxazoline)s. Two different architectures were synthesized: hydrophilic-grad-hydrophobic (mono-gradient) and hydrophobic-grad-hydrophilic-grad-hydrophobic (di-gradient) which contained a hydrophilic monomer, 2-ethyl-2-oxazoline (EtOx) and a hydrophobic monomer, 2-phenyl-2-oxazoline (PhOx).

The Long-Term Immunity of a Microneedle Array Patch of a SARS-CoV-2 S1 Protein Subunit Vaccine Irradiated by Gamma Rays in Mice.

Background/objectives: COVID-19 vaccines effectively prevent severe disease, but unequal distribution, especially in low- and middle-income countries, has led to vaccine-resistant strains. This highlights the urgent need for alternative vaccine platforms that are safe, thermostable, and easy to distribute. This study evaluates the immunogenicity, stability, and scalability of a dissolved microneedle array patch (MAP) delivering the rS1RS09 subunit vaccine, comprising the SARS-CoV-2 S1 monomer and RS09, a TLR-4 agonist peptide.

Elegant and Innovative Recoding Strategies for Advancing Vaccine Development.

Recoding strategies have emerged as a promising approach for developing safer and more effective vaccines by altering the genetic structure of microorganisms, such as viruses, without changing their proteins. This method enhances vaccine safety and efficacy while minimizing the risk of reversion to virulence. Recoding enhances the frequency of CpG dinucleotides, which in turn activates immune responses and ensures a strong attenuation of the pathogens.

In Situ Gelling Dexamethasone Oromucosal Formulation: Physical Characteristics Influencing Drug Delivery.

The study focuses on the development of an in situ gelling dexamethasone (DEX) oromucosal formulation designed for the treatment of aphthous stomatitis. Three series of formulations were prepared; a first series containing DEX suspended, a second series containing DEX and, in addition, mint essential oil (EO), and a third series containing EO and DEX solubilized in propylene glycol (PG). In the composition, polymers in the role of mucoadhesive agent were interchanged (hydroxypropyl methylcellulose (HPMC), hydroxypropyl cellulose (HPC), hydroxyethyl cellulose (HEC), methyl cellulose (MC), carboxymethyl cellulose (CMC), and sodium carboxymethyl cellulose (NaCMC).

Comparative Investigation of Vortex and Direct Plasma Discharge for Treating Titanium Surface.

Numerous studies have investigated the surface treatment of implants using various types of plasma, including atmospheric pressure plasma and vacuum plasma, to remove impurities and increase surface energy, thereby enhancing osseointegration. Most previous studies have focused on generating plasma directly on the implant surface by using the implant as an electrode for plasma discharge. However, plasmas generated under atmospheric and moderate vacuum conditions often have a limited plasma volume, meaning the shape of the electrodes significantly influences the local electric field characteristics, which in turn affects plasma behavior.
