This medication is classified as a humanized antibody targeting the immune system, as indicated by the "-alip" suffix in its name. Which best describes the primary mechanism of action of nirsevimab-alip in preventing RSV infection?

In contrast, a 58-year-old man with fair skin presents with a rapidly growing, irregularly bordered pigmented lesion on his back that was diagnosed as melanoma just 4 months after it was first noticed (IHC stain with Pan Melanoma 2 IHC stain is shown). Which of the following best explains the difference in clinical progression between equine and human melanomas? Special IHC stain containing a cocktail of antibodies to MART-1 and Tyrosinase
Q.69. A veterinаriаn is cаlled tо examine a 6-mоnth-оld pig from a small family farm where pigs are raised outdoors with access to wooded areas. The pig appears clinically normal with no signs of illness. As part of a research study on parasite prevalence in the region, muscle biopsy samples are collected. Histopathological examination reveals encysted larvae within striated muscle fibers. The larvae are coiled within a collagenous capsule surrounded by a network of new blood vessels. Labs show: Eosinophil count: 1.8 × 10^9/L (reference range: 0-0.8 × 10^9/L), Serum IgE: 980 ng/mL (reference range: 20-500 ng/mL), Creatine kinase: 195 U/L (reference range: 50-250 U/L)). What is the most likely diagnosis? Infected skeletal muscle
