The corrosion behavior of the TiTaNbZrAg alloys with different amounts of tantalum (0%, 10% and 20%) and with distinct surface topography (smooth and rough) was investigated in phosphate buffer solution (PBS) for long-time immersion (1000 h). By this approach, we expect to bring about new insights into the influence of both the amount of Ta in the alloy composition and the surface topography on the corrosion behavior of the Ti-based alloys. The corrosion resistance was studied by Open Circuit Potential (OCP), Potentiodynamic Polarization (PP), and Electrochemical Impedance Spectroscopy (EIS).

In the current research, a green plasticized magnesium ion-conducting biopolymer electrolyte was developed using simple solution casting method for Electric Double Layer Capacitors (EDLC) applications. The biopolymer Cellulose Acetate (CA) as the host polymer, with varying concentrations of BaTiO as the nanofiller, Mg(CFSO) as the ionic dopant, and PEG as the plasticizer.

- Human parainfluenza viruses (HPIVs) are a major cause of respiratory infections in kids, particularly during the COVID-19 pandemic when other respiratory viruses' patterns changed due to non-pharmaceutical interventions.
- A study analyzed nearly 19,339 respiratory samples from pediatric patients between 2021 and 2023, finding a total HPIV detection rate of 7.21%, with an increase in both test numbers and positive cases in 2023 compared to previous years.
- The study noted a seasonal shift in HPIV prevalence, with most cases occurring in younger children, and highlighted the rise of co-infections with other pathogens, stressing the importance of ongoing monitoring for public health responses.
Article Synopsis
- The study highlights the creation of environmentally friendly silver nanoparticles (AgNPs) using berries, showcasing their potential for use in medical applications like drug delivery and antimicrobial treatments due to their non-toxic nature.
- Characterization techniques confirmed the successful synthesis of AgNPs, which were found to have an average size of 23.5-28 nm and showed physical stability, as indicated by a negative zeta potential of -19.7 mV.
- The synthesized AgNPs demonstrated significant antioxidant properties, with a 79% inhibition of lipid peroxidation, and effective antimicrobial activity, presenting promising results against certain bacteria.
Objective: This study aims to observe the outcomes of topical phenytoin treatment in healing neuropathic diabetic foot ulcers with mild infection and compare these outcomes with those obtained from conventional dressing methods.
Methods: A retrospective observational study was conducted by reviewing the medical records of patients with neuropathic diabetic foot ulcers treated at a tertiary care center from 2015 to 2020. Two groups were identified: (1) patients treated with topical phenytoin (for ulcers measuring less than 5 cm, a dosage of 100 mg was used; for ulcers measuring between 5 cm and 9 cm, a dosage of 150 mg was used; for ulcers measuring between 10 cm and 15 cm, a dosage of 200 mg was used; and for ulcers measuring greater than 15 cm, a dosage of 300 mg was used.
