Background: Otitis media with effusion (OME) is associated with comorbidities such as allergic rhinitis, gastroesophageal reflux disease, asthma, and more. Many of these comorbidities can be caused by type 2 inflammation (T2I). This study aims to determine the risk of undergoing OME surgery in patients with and without T2I disease.

Article Synopsis
  • Age-related hearing loss (ARHL) is linked to inner-ear factors, but this study explores the lesser-understood impact of age-related changes in the middle ear using a finite element model.
  • The analysis compared clinical data from younger (average age 38) and older adults (average age 64), focusing on air-bone gap (ABG) measurements at various frequencies through pure-tone audiometry.
  • Results showed significant conductive hearing loss in older adults at 1.0 kHz, with more pronounced damage to the basilar membrane in the speech frequency range, suggesting that aging worsens hearing challenges when exposed to higher sound levels.

The study aimed to evaluate the impact of occupational noise on hearing loss among healthcare workers using audiometry. A longitudinal study was conducted with a six-month follow-up period in a hospital with 21 participants, divided into high-noise-exposure (HNE) and low-noise-exposure (LNE) groups. Mean noise levels were higher in the HNE group (70.

Objective: To investigate the association between the prevalence of cyclosporin A-induced gingival overgrowth and the expression of the epithelial-to-mesenchymal transition factors in the gingival tissues of renal transplant patients.

Background: Gingival overgrowth (GO) is a frequent complication in organ transplant patients treated with the immunosuppressant cyclosporin A (CsA). The epithelial-to-mesenchymal transition (EMT) is considered a factor contributing to CsA-induced GO.

Background And Objective: Noise is a common occupational and environmental hazard; however, little is known about the use of computational tools to quantitively analyze data on basilar membrane (BM) damage in noise-induced hearing loss (NIHL). Here, we established a comprehensive three-dimensional finite-element human ear model to quantify the impact of noise exposure on BM and perilymph fluid.

Methods: We used auditory risk units (ARUs) to evaluate the BM damage for subjects (3 men and 5 women; mean age, 32.

Automated inspection has proven to be the most effective approach to maintaining quality in industrial-scale manufacturing. This study employed the eye-in-hand architecture in conjunction with deep learning and convolutional neural networks to automate the detection of defects in forged aluminum rims for electric vehicles. RobotStudio software was used to simulate the environment and path trajectory for a camera installed on an ABB robot arm to capture 3D images of the rims.

Background And Objectives: The Young's modulus of the tympanic membrane (TM) is an important modeling parameter in computer simulations of the sound transmission in the ear. Understanding the material mechanics of the TM is essential to improve the coupling between the tympanic membrane and the auditory ossicles. However, the impact of the age-related Young's modulus of the TM on sound transmission is not well known.

To resolve the issue of sewage fluctuation and discontinuity in a rural district of China, a new operation mode of replenishing the mixture of fermentation liquor and tail water during the off-flow period was proposed, and the nutrient removal performance of a pilot-scale A/O system with this operation mode was investigated. The results of beaker experiments found that the mixture of tail water and fermentation liquor at a ratio of 12:1 had better denitrification and phosphorus release/absorption characteristics than the raw water, and theoretically had the function of enhancing denitrification and phosphorus removal performances. The results of a 97 d pilot test showed that the removal efficiency of TN and TP was improved after the system was adjusted from the constant flow mode to this new operation mode, and the average removal rate of TN and TP increased from 69.

Fabricating Ti alloy based dental implants with defined porous scaffold structure is a promising strategy for improving the osteoinduction of implants. In this study, we use Laser Beam Melting (LBM) 3D printing technique to fabricate porous Ti6Al4V dental implant prototypes with three controlled pore sizes (200, 350 and 500 μm). The mechanical stress distribution in the surrounding bone tissue is characterized by photoelastography and associated finite element simulation.
