Comparative analysis of spinal flexion angles during smartphone use in toilet: a randomized cross-over with three-period study.

: The purpose of this study was to quantify the impact of smartphone use while sitting on the toilet on the spinal flexion angles and the time effect. : Measurements of the spinal flexion angles in the sagittal plane were made by thirty participants while they sat on the toilet for 10 min, using a smartphone in either one, both, or neither hand. The individual's forehead, cervical, thoracic and lumbar spinal areas were each fitted with five different inertial motion sensors.

HSP27/IL-6 axis promotes OSCC chemoresistance, invasion and migration by orchestrating macrophages via a positive feedback loop.

Novel strategies to disrupt tumor progression have emerged from studying the interactions between tumor cells and tumor-associated macrophages (TAMs). However, the molecular mechanisms of interactions between tumor cells and TAMs underlying oral squamous cell carcinoma (OSCC) progression have not been fully elucidated. This study explored the molecular mechanism of the HSP27/IL-6 axis in OSCC chemoresistance, invasion, and migration.

Tested mirror precision alignment system using a pinhole point diffraction interferometer based on machine vision.

In the pinhole point diffraction interferometer (PPDI), proper alignment between the reflection spot of the tested component and the pinhole is critical to obtain accurate interferograms. At present, adjusting for tilt error requires manual manipulation, and defocus error cannot be corrected. These limitations impede the instrumentation process of PPDI.

Identification of multicohort-based predictive signature for NMIBC recurrence reveals SDCBP as a novel oncogene in bladder cancer.

Background: Despite surgical and intravesical chemotherapy interventions, non-muscle invasive bladder cancer (NMIBC) poses a high risk of recurrence, which significantly impacts patient survival. Traditional clinical characteristics alone are inadequate for accurately assessing the risk of NMIBC recurrence, necessitating the development of novel predictive tools.

Methods: We analyzed microarray data of NMIBC samples obtained from the ArrayExpress and GEO databases.
