Collapsing glomerulopathy associated with parvovirus B19 and systemic lupus erythematosus in a patient with APOL1 high-risk variant for nephropathy.

Collapsing glomerulopathy (CG) has a severe course typically associated with viral infections, especially HIV and parvovirus B19, systemic lupus erythematosus (SLE), among other etiologies. A 35-year-old woman with recent use of a JAK inhibitor due to rheumatoid arthritis presented with a 2-week history of fever, cervical adenopathy, and facial erythema.

Snaplage residue as a fiber source for finishing beef cattle under grazing: effects on residue characteristics, cattle behavior and performance, and carcass traits.

The snaplage residue presents itself as a potential alternative roughage source in finishing systems, owing to its high fiber concentration which aids in maintaining rumen health. Nevertheless, the performance of animals will hinge on both the allowance and the nutritive value it offers. This study aimed to evaluate different stocking rates of heifers grazing snaplage residue as an exclusive source of fiber on finishing phase performance.

New Behavior Records of the Oxysternon palemo Castelnau, 1840 (Coleoptera: Scarabaeidae: Scarabaeinae) in Cerrado.

The present study reports new behavioral records for Oxysternon palemo Castelnau, 1840 in Cerrado. According to its nesting habits and resource allocation, this species of dung beetle is traditionally classified as coprophagous and paracoprid, transporting portions of dung through tunnels excavated below the resource. We observed a male individual moving a pequi seed (Caryocar brasiliensis Cambess.
