Previous studies suggest that some insects require dietary arginine because they cannot synthesize this amino acid through the urea cycle. To determine whether this finding applies to all insects and what its metabolic implications are, we analysed the conservation of 20 genes involved in arginine biosynthesis and metabolism in the genomes of 150 species from 11 taxonomic orders. Our results showed that no insect can synthesize arginine via the urea cycle, as ornithine carbamoyltransferase is absent from all genomes analysed.

Methods: Thirty-six feral cats were randomly allocated to group control (C) or group QLB with 0.4 mL kg of 0.
Schwannomas are nerve sheath tumors arising from Schwann cells. Schwannomas of the intercostal nerve are extremely rare, with limited published literature. These tumors are generally regarded as benign asymptomatic.

Methods: A nationwide cross-sectional online survey was conducted with licenced physical therapists recruited through professional networks and social media. The questionnaire, developed based on the CHERRIES checklist, assessed participants' knowledge, clinical strategies, and perceived barriers related to self-efficacy and self-management interventions.
Tuberculosis (TB) is the most common comorbidity in people living with HIV/AIDS (PLWH), including those under antiretroviral treatment. PLWH are 28 times more likely to develop TB in Brazil, the leading cause of HIV-related deaths globally, with approximately 161,000 reported deaths worldwide in 2023. Early diagnosis of latent tuberculosis infection (LTBI) and prophylactic therapy can reduce TB cases, prevent disease progression, and decrease transmission in high-risk populations.
