Non-Classical Congenital Adrenal Hyperplasia (NCCAH) due to partial 21-hydroxylase deficiency is a frequent and often underdiagnosed cause of hyperandrogenism in women. We report the case of a 39-year-old woman presenting with severe hirsutism. Hormonal evaluation revealed elevated 17-Hydroxyprogesterone (17OHP), confirmed after ACTH stimulation, consistent with NCCAH. Imaging findings were normal. This case highlights the importance of systematic screening for this condition in the…

Ectopic parathyroid adenomas are rare and usually present with biochemical hyperparathyroidism. They most frequently occur in the mediastinum or thymic region. Localization within a lymph node along the recurrent laryngeal nerve chain is extremely rare. We report a case of a 70-year-old woman in whom a non-functioning ectopic parathyroid adenoma was incidentally discovered within a lymph node of the right recurrent laryngeal nerve chain during surgery for a suspicious thyroid nodule.…

Systematic reviews derive their credibility from the comprehensive identification of relevant evidence. In medical science research, systematic reviews have traditionally been pursued through searches of multiple curated bibliographic databases, a practice reinforced by methodological convention and consensus reporting frameworks. However, this approach developed in an earlier era of scientific communication, when dissemination was slower, more journal-centered, and more tightly bounded by…

The growing demand for high-efficiency electric propulsion systems in modern satellite missions has intensified interest in alternative propellants for Hall-effect thrusters (HETs). Although xenon remains the standard propellant due to its favorable atomic mass and low ionization energy, its high cost and limited global supply motivate the exploration of viable substitutes such as krypton and argon. This study presents a comprehensive comparative analysis of noble gas propellants for Hall…

This tutorial review provides a comprehensive exploration of advanced Structured Query Language (SQL) techniques, building upon foundational database knowledge to equip aspiring programmers and administrators with sophisticated data management skills. The review covers ANSI SQL standards applicable across major database management systems, including Oracle, SQL Server, and MySQL [1, 4]. Key topics include the intricate use of aggregate functions for data summarization and statistical…

This report presents a comprehensive study on the implementation and simulation of advanced flight control systems for Unmanned Aerial Vehicles (UAVs). The work is divided into two primary domains: the practical application of the Pixhawk Pilot Support Package (PSP) within the MATLAB/Simulink environment and the theoretical construction of a six-degree-of-freedom (6 DOF) dynamic model for fixed-wing aircraft. By leveraging the PSP, we demonstrate the integration of hardware-in-theloop (HIL)…

Background and Purpose: Chronic neck pain (CNP) is among the most prevalent occupational health complaints in desk-based workers globally, with reported lifetime prevalence exceeding 70% in office populations. Despite substantial evidence supporting exercise-based physiotherapy for CNP, patient adherence to unsupervised postural correction programs remains persistently poor. Vibrotactile biofeedback — the delivery of real-time haptic alerts via skin vibration when a…

Antisocial personality is a type of personality characterized by persistent violation of social norms, infringement on others’ rights, and a lack of responsibility. It is closely associated with aggressive behavior, criminal activity, and poor social adaptation. With the increasing prominence of mental health issues, the formation mechanisms and intervention pathways of antisocial personality have gradually become a major focus of research. Existing studies suggest that antisocial…

Background: The location of lesions causing hearing loss in patients with cerebral palsy remains unclear.

Objectives: To evaluate the incidence and characteristics of auditory pathologies in children with various forms of cerebral palsy.

Methods: This prospective observational study enrolled 42 children with a confirmed diagnosis of cerebral palsy. All participants underwent comprehensive clinical examinations;…

With the rapid development of the digital economy, digital assets have gradually become an important driving force for the transformation of the financial system. Based on technologies such as Blockchain, digital assets have played a significant role in improving financial efficiency, promoting product innovation, and advancing inclusive finance. At the same time, their characteristics of decentralization and transparency have, to some extent, provided new pathways for consumer…
