Introduction: Mitochondrial membrane potential (MMP) and mitochondrial mass (MM) affect mitochondrial function and lymphocyte activation, but few studies on HBV infection exist. This study aimed to investigate the regulatory mechanism of mitochondrial dysfunction during HBV infection and its clinical significance by analyzing the alterations of MM and MMP in peripheral blood immune cells.

Methods: The study enrolled 90 participants, including healthy volunteers(HC) and patients with HBV infection, HBV patients were divided into chronic hepatitis B patients (CHB) and liver cirrhosis (LC) according to the study, and CHB was also divided into an inflammation group and a non-inflammation group.

Article Synopsis
  • Premolar extraction is an effective treatment for patients with bimaxillary dentoalveolar protrusion, particularly when using clear aligners (CAs) which close extraction spaces but can cause unwanted tooth movements, especially in cases where 2nd premolars are removed.
  • This study analyzed two models of bimaxillary dentoalveolar protrusion to understand the effects of extracting either the 1st or 2nd premolars on tooth tipping and anchorage loss using finite element analysis.
  • Results indicated that extracting 1st premolars resulted in more significant changes in tooth angulation and a greater tendency for distal tipping compared to 2nd premolars, with the maxillary arch showing more mesial tipping

The biological activities of natural products (NPs) provided precious resources for the development of new drugs. Numerous studies have shown that statins exhibit cytotoxic potential, which is now an extensive focus of investigation. Herein, a remarkably efficient method for modification of statins using hexadehydro-Diels-Alder (HDDA) arynes has been described.

To compare the effects of expansion screw with maxillary protractor and clear aligners combined with maxillary protractor on the maxilla and maxillary dentition of mixed dentition patients with class Ⅲ skeletal malocclusion using finite element analysis, further providing clinical guidance for clear aligner treatment. A finite element model was established based on maxillofacial cone-beam CT data of a 10-year-old boy with mixed dentition, class Ⅲ skeletal malocclusion, who visited Department of Orthodontics, School of Stomatology, The Fourth Military Medical University in January, 2024. The expander with protractor group (group A) and the clear aligners with protractor group (group B) were divided.
