Purpose: This work described a new species of Ceratomyxa, based on morphological and phylogenetic analyzes of myxospores collected from the gallbladder of the fish Astyanax mexicanus.
Methods: Sixty-two specimens were captured, between December 2022 and February 2024, in the Flexal River, in the community of Tessalônica, state of Amapá. The specimens were transported alive to the Laboratory of Morphophysiology and Animal Health, at the State University of Amapá, where the studies were carried out.

During lung development, the embryonic airway originates as a wishbone-shaped epithelial tube, which undergoes a series of branching events to build the bronchial tree. This process depends crucially on cell proliferation and is thought to involve distinct branching modes: lateral branching, wherein daughter branches emerge along the length of a parent branch, and bifurcations, wherein the tip of a parent branch splits to form two new daughter branches. The developing airway is fluid-filled, and previous studies have shown that altered luminal pressure can influence rates of branching morphogenesis.

It was hypothesized that the stem size planned with accordance to the diaphyseal canal width alone can accommodate the distal femur successfully with no sizing mismatch. Forty-six patients (53 hips) suffering from secondary osteoarthritis due to hip dysplasia scheduled for total hip arthroplasty (THA) with a subtrochanteric transverse shortening osteotomy were included.
