Impact of adipocytes on ultrasound evaluation of parathyroid adenomas.

Purpose: Parathyroid lipoadenomas are difficult to recognize preoperatively; hence, they may remain undetected. Difficulty in recognition is thought to be due to the adipocytes present in the tumor. This study aimed to clarify the impact of adipocytes as a component of parathyroid adenomas on ultrasound evaluation.

Quality of Communication Between Professors and University Students in the Process of Learning.

Teaching requires the incorporation of communication skills, and these potentials may affect the outcomes of the learning process. This study evaluated the quality of communication between professors and students during the process of learning Dentistry. A questionnaire was developed and applied to evaluate their perceptions about their communications in an undergraduate Dentistry course.

Characterization of an uncooled mid-infrared Schottky photodetector based on a 2D Au/PtSi/p-Si nanohole array at a higher light modulation frequency.

In this study, an uncooled 2D nanohole array PtSi/p-Si Schottky mid-infrared (MIR) photodetector, which is essential for on-chip Si-based low-barrier MIR detectors, is presented. Room temperature operation introduces susceptibility to thermal noise and can impact stability. Through modulation frequency and reverse bias optimization, the stability improved by 7 times at 170 Hz and -3.

[Anatomical Repair of Total Arch Replacement for Stanford Type B Subacute Aortic Dissection with Aberrant Right Subclavian Artery:Report of a Case].

A 45-year-old man complaining of chest and back pain due to acute aortic dissection was referred to our department. A contrast enhanced computed tomography( CT) scan showed Stanford type B aortic dissection with Kommerell diverticulum and aberrant right subclavian artery. The patient underwent antihypertensive treatment for one month.

Electromechanically reconfigurable plasmonic photodetector with a distinct shift in resonant wavelength.

Plasmonic photodetectors have received increasing attention because their detection properties can be designed by tailoring their metal structures on surfaces without using any additional components. Reconfiguration of the plasmonic resonant state in a photodetector is relevant for various applications, including investigating in situ adaptive detection property changes, depending on the situation, and performing single-pixel spectroscopy in geometrically limited regions. However, the spectral responsivity change with conventional reconfiguration methods is relatively small.
