Hereditary hearing loss (HHL), a genetic disorder that impairs auditory function, significantly affects quality of life and incurs substantial economic losses for society. To investigate the underlying causes of HHL and evaluate therapeutic outcomes, appropriate animal models are necessary. Pigs have been extensively used as valuable large animal models in biomedical research.

Article Synopsis
  • Fulvic acid (FA) plays a significant role in agriculture, ecology, and medicine, prompting research into its molecular structure and composition.
  • This study focused on separating coal-based FA from Inner Mongolia lignite using microwave-assisted oxygenation and utilized various analytical techniques to determine its microscopic structure.
  • The findings revealed that FA consists of multiple functional groups with a specific molecular formula (CHNO) and a relative molecular mass of 886, providing valuable insights for future research applications.

Purpose: To achieve functional and esthetic results, implants must be placed accurately; however, little information is available regarding the effect of surgical templates on the accuracy of implant placement. Thus, the aim of this study was to measure the deviation between actual and planned implant positions, and determine the deviation caused by the surgical template.

Materials And Methods: Jaws from 16 patients were scanned using cone beam computed tomography (CBCT).

Background: The occurrence of mandibular defects caused by tumors has been continuously increasing in China in recent years. Conversely, results of the repair of mandibular defects affect the recovery of oral function and patient appearance, and the requirements for accuracy and high surgical quality must be more stringent. Digital techniques--including model reconstruction based on medical images, computer-aided design, and additive manufacturing--have been widely used in modern medicine to improve the accuracy and quality of diagnosis and surgery.

To investigate the association between the single nucleotide polymorphisms (SNPs) in adiponectin gene promoter and essential hypertension (EH) in Chinese Korean and Han of Yanbian area, 220 EH patients and 268 normotensive control individuals were enrolled. PCR and direct DNA sequencing were used to determine the -11426A>G (rs16861194), -11391G>A (rs17300539), -11377C>G (rs62620185), -11156insCA (rs60806105), and -11043C>T (rs76786086) SNPs in the promoter region of adiponectin gene. Total cholesterol (TC), the triglyceride (TG), fasting plasma glucose (FPG), low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein-cholesterol (HDL-C) levels were examined by oxi-dase method.
