Following myocardial infarction (MI), the accumulation of CD86-positive macrophages in the ischemic injury zone leads to secondary myocardial damage. Precise pharmacological intervention targeting this process remains challenging. This study engineered a nanotherapeutic delivery system with CD86-positive macrophage-specific targeting and ultrasound-responsive release capabilities.

Background: Increasing evidence suggests that SARS-CoV-2 infection may lead to early onset and aggravation of pre-existing vascular dementia and Alzheimer's disease. Methylene tetrahydrofolate reductase (Mthfr) is a critical enzyme in folate metabolism, also required for optimal brain function. Mthfr deficient mice display cognitive impairments and neurovascular deficits and polymorphisms in MTHFR increases dementia risk.

CHU Saint-Étienne, Service de Rhumatologie, Mines Saint-Etienne, INSERM, SAINBIOSE U1059, Université Jean Monnet Saint-Étienne, Saint-Etienne, France.

Background: Methotrexate (MTX) is the first-line treatment for Rheumatoid Arthritis (RA), yet 30%-50% of RA patients develop resistance to MTX, which can manifest several years after treatment initiation.

Objective: This study investigates the relationship between erythrocyte methotrexate polyglutamates (MTX-PGs) subtype concentrations and clinical disease activity in RA patients undergoing long-term MTX treatment.

Methods: In this cross-sectional study, patients on a stable dose of subcutaneous MTX for several years were included.

Background And Purpose: Recommended treatment of urothelial muscle-invasive bladder cancer (MIBC) is cisplatin-based neoadjuvant chemotherapy (NAC) followed by cystectomy, but there are challenges with low utilization of NAC. We aimed to evaluate the utilization of NAC, perioperative complications and oncological efficacy in a real-world setting.

Patients And Methods: All patients operated with radical cystectomy at the University Hospital of North Norway during 2011-2021 for MIBC were included.

Background: This study investigated the effects of phototherapy on serum BH4 levels, evoked potentials, and cognitive impairment in post-stroke depression patients.

Methods: We conducted a prospective study with 160 post-stroke depression patients, randomly assigned to an experimental group receiving daily 40 min of phototherapy alongside routine treatment, and a control group receiving only routine treatment. Serum tetrahydrobiopterin (BH4) levels were measured via ELISA.
