Fuel cells have become increasingly important in recent years because of their high energy efficiency and low environmental impact. However, key challenges remain in the widespread adoption of fuel-cell vehicles, including reducing Pt usage in catalysts and improving their durability. In this study, a high-performance Pt@carbon-dot-film core-shell catalyst was successfully synthesized using a nonequilibrium reaction field, , solution plasma (SP) process, by adjusting the electrolyte pH.

Purpose: To examine the effect of romosozumab administration on reducing the incidence of proximal junctional kyphosis (PJK), particularly PJK due to fractures (PJK-Fx), in patients undergoing spinal corrective fusion surgery.
Design: Retrospective cohort study.
Background: Out-of-hospital cardiac arrest (OHCA) has a poor prognosis. Patients with shockable rhythms often have better outcomes than those with nonshockable rhythms. A previous study reported a decline in shockable rhythms and poorer outcomes with the use of beta-blockers before OHCA.

Although these conditions rarely occur together, we present a case of a 54-year-old female with plantar malignant melanoma who developed hypothyroidism after the second cycle of pembrolizumab and then uveitis after the fifth cycle. Hypothyroidism was treated with levothyroxine, and uveitis was managed with corticosteroids.

- Non-tuberculous mycobacteriosis (NTM) is a rare infection that can affect the lungs, skin, or spread throughout the body, with cutaneous infections often linked to weakened immune systems or contaminated sources.
- A case study of a 54-year-old man with a persistent skin ulcer showed that his initial treatment was ineffective, leading to HIV testing which revealed advanced infection.
- Proper antimicrobial treatment for NTM and the start of antiretroviral therapy significantly improved the patient's condition, demonstrating the need to consider underlying immunosuppressive factors in persistent skin infections to prevent serious complications.
