Routine radiographs in the follow-up study of Legg-Calvé-Perthes disease patient have generally been plain radiographs of the anteroposterior and frog-leg lateral view. Recently, several reports have found that osteochondritis dissecans can develop in 2% to 4% of Legg-Calvé-Perthes disease patients. Early roentgenographic recognition of this lesion is very important for its long-term prognosis. However, follow-up examination of the lesion using plain radiography is sometimes not satisfactory in terms of delineating the lesion. Accordingly, the authors performed computed tomography and three-dimensional reconstruction in 13 hips with osteochondritis dissecans following Legg-Calvé-Perthes disease and were able to obtain more precise information on the extent of the involvement, the degree of healing, the stability of the osteochondral fragment, and the location of the dislocated loose body.

Studies have shown that circRNAs play an important regulatory role in trophoblast function and embryonic development. Based on sequencing and functional experiments, we found that hsa_circ_0069443 can regulate the function of trophoblast cells, and its presence is found in the exosomes secreted by trophoblast cells. It is known that exosomes mediate the interaction between the uterus and embryo, which is crucial for successful pregnancy.

Forest edges, where humans, mosquitoes, and wildlife interact, may serve as a nexus for zoonotic arbovirus exchange. Although often treated as uniform interfaces, the landscape context of edge habitats can greatly impact ecological interactions. Here, we investigated how the landscape context of forest edges shapes mosquito community structure in an Amazon rainforest reserve near the city of Manaus, Brazil, using hand-nets to sample mosquitoes at three distinct forest edge types.
