Crab bioturbation alters the community assemblies of abundant and rare bacteria on an intertidal wetland in the Yellow River estuary.

Introduction: Revealing assembly patterns of abundant and rare bacteria is pivotal for comprehending the responses of soil bacterial community to environmental changes. Crabs exert significant impacts on soil environments through their frequent burrowing activities in intertidal wetlands. However, there remains a paucity of knowledge regarding the influencing mechanism of crab bioturbation on community assemblies of abundant and rare bacteria.

The relationship between CTA performances and cardiac function indicators in myocardial bridge and mural coronary artery.

Objective: To investigate the relationship between computed tomography angiography (CTA) performances and cardiac function indicators in patients with myocardial bridge and mural coronary artery (MB-MCA).

Methods: The clinical data of 60 patients with MB-MCA receiving CTA in the First Hospital of Zhangjiakou from January 2021 to February 2022 were analyzed retrospectively. The patients were divided into different groups based on CTA performances, including the degree of stenosis of the left anterior descending (LAD) MCA, whether there was atherosclerosis in the anterior segment of MB of LAD branch, the MB thickness, and the degree of stenosis of the LAD branch.

Diagnostic value of myocardial bridge-mural coronary artery vascular morphology based on CTA technique.

Objective: To investigate the diagnostic value of coronary CT angiography (CTA) technique on the vascular morphology of the myocardial bridge-mural coronary artery (MB-MCA).

Methods: In this retrospective study, 180 patients with suspected MB-MCA attending Hebei Huaao Hospital from February 2019 to February 2020 were analyzed. The image quality, myocardial bridge distribution, type, length, and degree of stenosis of wall coronary vessels were compared between CTA and Coronary angiography (CAG).
