Article Abstract
Background: The transoral endoscopic thyroidectomy vestibular approach (TOETVA) is the most recently developed minimally invasive technique with no skin incision. For tissue dissection and bleeding control, the use of proper energy devices is very important in endoscopic thyroid surgery. To date, there have been no clinical studies reported regarding which energy device is better in TOETVA, ultrasonic shears or advanced bipolar device. The aim of our study is to determine which energy device is more useful for TOETVA.
Methods: This study was designed as an open-label, prospective randomized controlled trial in a single university hospital. Patients were randomly assigned to the ultrasonic group or advanced bipolar group before the surgery. From June 2020 to May 2022, 40 patients were enrolled (20 patients were assigned to the ultrasonic group, and 20 patients were assigned to the advanced bipolar group). Primary endpoints were operation time for lobectomy, number of camera cleanings, and blood loss during the lobectomy. Secondary endpoints were pain score, postoperative drainage, and blood chemistry. A single endocrine surgeon had performed all surgeries.
Results: There were no significant differences between the two groups in age, sex, body mass index (BMI), tumor location, preoperative cytology, or surgical extent. The time for lobectomy was significantly shorter in the advanced bipolar group (33.8±6.4 41.9±9.0 minutes, P=0.002). The number of camera cleanings was significantly lower in the advanced bipolar group (2.9±1.6 5.8±2.5 times, P<0.001). Estimated blood loss was also significantly less in the advanced bipolar group (11.5±17.3 81.8±99.5 mL, P=0.004). Postoperative hospital stays, drainage, pain score, laboratory findings, and complications were not significantly different between the two groups.
Conclusions: According to this study, advanced bipolar device showed better performance, with a shorter operation time, less camera cleaning, and less blood loss. We suggest that advanced bipolar device can be a better choice in TOETVA.

The human stomach features distinct, regionalized functionalities along the anterior-posterior axis. Historically, studies on stomach patterning have used animal models to identify the underlying principles. Recently, human pluripotent stem (hPS)-cell-based gastric organoids for modelling domain-specific development of the fundic and antral epithelium are emerging.

Electroencephalography (EEG) is a comparatively inexpensive and non-invasive recording technique of neural activity, making it a valuable tool for biomarker discovery in transcranial magnetic stimulation (TMS). This systematic review aimed to examine mechanistic and predictive biomarkers, identified through TMS-EEG or resting-state EEG, of treatment response to TMS in psychiatric and neurocognitive disorders. Nineteen articles were obtained via Embase, APA PsycInfo, MEDLINE, and manual search; conditions included, unipolar depression (k = 13), Alzheimer's disease (k = 3), bipolar depression (k = 2), and schizophrenia (k = 2).

3D printing, as a versatile additive manufacturing technique, offers high design flexibility, rapid prototyping, minimal material waste, and the capability to fabricate complex, customized geometries. These attributes make it particularly well-suited for low-temperature hydrogen electrochemical conversion devices-specifically, proton exchange membrane fuel cells, proton exchange membrane electrolyzer cells, anion exchange membrane electrolyzer cells, and alkaline electrolyzers-which demand finely structured components such as catalyst layers, gas diffusion layers, electrodes, porous transport layers, and bipolar plates. This review provides a focused and critical summary of the current progress in applying 3D printing technologies to these key components.

Purpose: To characterize a no b-wave (nob) mouse model of congenital stationary night blindness (CSNB) caused by a Grm6 variant that disrupts photoreceptor-to-bipolar cell signaling. Additionally, we aim to evaluate the efficacy of gene therapy in restoring visual function.
Methods: The nob mouse was generated through selective breeding to regenerate the nob phenotype.
Polygenic scores for psychiatric traits mediate the impact of multigenerational history for depression on offspring psychopathology.

A family history of depression is a well-documented risk factor for offspring psychopathology. However, the genetic mechanisms underlying the intergenerational transmission of depression remain unclear. We used genetic, family history, and diagnostic data from 11,875 9-10 year-old children from the Adolescent Brain Cognitive Development study.
