Objective assessment of visual attention in orthognathic surgery training based on eye tracking.

The aim of this study was to investigate the differences in visual attention between novices and orthognathic experts, as well as to provide evidence for use in developing and optimizing training strategies for orthognathic surgery. Novice and orthognathic experts were recruited, and their distributions of visual attention were monitored via an eye-tracking device while they watched orthognathic surgery videos. The percentages of visual fixation duration devoted to the areas of interest - surgical objects, instruments controlled by the main surgeon, and instruments controlled by the assistants - in each orthognathic surgery section were analyzed and compared between the two groups using repeated-measures factorial analysis of variance (ANOVA).

Exploring the distribution of visual attention in genioplasty trainees using eye-tracking technology.

Purpose: This study aimed to investigate the visual attention of genioplasty trainees using eye-tracking technology, with the goal of providing insights for optimizing genioplasty training strategies.

Methods: Trainees were recruited for the study, and their visual attention distribution was monitored with an eye-tracking device while they watched a genioplasty procedure video. The percentage of fixation durations dedicated to areas of interest (surgical objects, instruments manipulated by the primary surgeon, and instruments controlled by assistants) were analyzed for each phase of the procedure.

The effectiveness of tamsulosin hydrochloride with terazosin combination therapy for chronic prostatitis Type-III b.

Objectives: To study the therapeutic effects of combined tamsulosin hydrochloride and terazosin treatment for patients with chronic prostatitis Type-III b.

Methods: This study involved 180 patients with chronic prostatitis Type-III b treated between January 2018 and December 2020 conducted at Nanhua Hospital Affiliated to Nanhua University. Patients were randomly divided into two equal groups: one receiving oral terazosin hydrochloride tablets only (control group), and one orally receiving both tamsulosin hydrochloride sustained-release tablets and terazosin hydrochloride tablets (observation group).

Perception of the Nose and Lower Face Before and After Orthognathic Surgery in Subjects with Dento-maxillofacial Deformities: An Eye-Tracking Study.

Background: Dento-maxillofacial deformities are often associated with nasal deviation, and patients often complain of nasal deviation after orthognathic surgery. This study aimed to quantitatively evaluate the facial visual attention given to dento-maxillofacial deformities accompanying nasal deviation from the perspective of patients and determine whether orthognathic surgery could alter this outcome.

Methods: The scanning paths of 137 patients were recorded using an eye-tracking device; recordings were made while the patients viewed images of dento-maxillofacial deformities associated with various degrees of nasal deviation before or after orthognathic surgery.

Do Orthognathic Patients and Persons Without Facial Deformities Have Different Visual Attention to Menton Deviation?

Purpose: This study aimed to quantify how menton deviation influenced facial visual attention of orthognathic patients and persons without facial deformities, and to explore differences between them.

Materials And Methods: The visual scanning paths of 260 participants (Group I, 130 orthognathic participants; Group II, 130 participants without facial deformities) while observing images reflecting normal subjects and those with different menton deviation degrees were recorded with an eye-tracking device. The fixation duration [FD] and first fixation time [FFT]) on the areas of interest for each group were compared.

Facial visual attention to menton deviation: An objective evaluation by laypeople.

Purpose: This study aimed to quantitatively evaluate whether the severity of menton deviation (MD) influenced facial perceptions of laypeople. We also aimed to determine the effectiveness of surgery in normalizing the distribution of the facial visual attention of laypeople.

Methods: The scanning paths of 177 laypeople were recorded using an eye tracking device while observing images of individuals without MD and pre- and post-treatment subjects with different degrees of MD.

MiRNA-200a induce cell apoptosis in renal cell carcinoma by directly targeting SIRT1.

Accumulating evidence indicates that microRNAs are implicated in tumor initiation and progression through negatively regulating oncogenes or tumor suppressor genes. In the present study, we report that the expression of miR-200a was significantly lower in renal cell carcinoma (RCC) specimens and RCC cell lines. Restoration of miR-200a suppressed cell growth, arrested cell cycle progression, and promoted cell apoptosis in RCC cell lines.
