Sustained peripheral nociceptive input disrupts interstimulus-interval-dependent sensory gating in the rat primary somatosensory cortex

Sensory gating is processed in thalamocortical pathways and depends significantly on the interstimulus interval. Somatosensory symptoms and temporal discrimination disturbances are associated with nociceptive conditions. We aimed to investigate the effects of capsaicin applicatio...

Effect of 3200 MHz Radiofrequency Fields on MCF-7 and L929 Cell Lines

Objective: The use of technological devices emitting radio frequency fields(RFF) is increasing day by day. Nowadays, low-frequency RFF has begun to be used in cancer treatment as a non-invasive method. However, the time-dependent effects of high-frequency RFF on healthy and cance...

The effect of stone size on the success of fluoroscopy-free retrograde intrarenal surgery

Abstract Background Fluoroscopy is routinely used during retrograde intrarenal surgery (RIRS) but exposes both patients and operating room staff to ionizing radiation. Fluoroscopy-free RIRS has emerged as an alternative strategy; however, the influence of stone size on surgical s...

Exploring exercise behavior, physical activity level, and perceived barriers in women with lipedema: a case-control study

Lipedema is a chronic adipose tissue disorder characterized by pain and disproportionate fat distribution. Although exercise is an important component of lipedema management, evidence regarding exercise behavior, physical activity, and related barriers remains limited. This study...

The Blastocystis-colorectal cancer hypothesis: correlation is not causation

Introduction Emotional empathy is a key component of medical professionalism, enhancing doctor–patient communication, trust, treatment adherence, and clinical outcomes. However, research suggests that emotional empathy tends to decline during medical education, with potential neg...

Modular unmanned ground vehicle architecture for search and rescue operations: autonomous SLAM and AI-driven thermal victim detection

Purpose The catastrophic effects of natural disasters on human life and the critical importance of timely response have significantly increased the demand for autonomous search and rescue (SAR) technologies such as unmanned ground vehicles (UGVs) and unmanned aerial vehicles (UAV...

Temperature–Load‐Dependent Wear Transitions of PH 15–5 Stainless Steel Under Dry Sliding

The dry sliding behavior of PH 15–5 precipitation‐hardened stainless steel was investigated at room temperature and −40 °C under 10 and 20 N using reciprocating ball‐on‐disc tests. A 6 mm WC–Co ball was used at 34 mm s −1 for 30 min, corresponding to 61.2 m sliding distance. Fric...

The Effect of Parental Education on the Early Literacy Skills of Children With Low Vision

Introduction The study examines the impact of the early literacy parent education program for children with low vision (ELPEP-CLV) on parents’ ability to promote their children's early literacy skills at home. The program is designed to improve the literacy outcomes of children a...

Effect of CFRP strip width, spacing, and anchors on the axial and flexural performance of RC columns

This study experimentally investigates the effectiveness of strengthening reinforced concrete (RC) columns with carbon fiber-reinforced polymer (CFRP) strips to enhance their axial load capacity and nonlinear deformation behavior under both concentric and eccentric axial loading....

Expert evaluation of AI-assisted scenario design for interactive problem based learning environments in medical education

Problem-based learning (PBL) is an interactive learning approach in which students develop understanding through collaborative inquiry, hypothesis generation, and interpretation of clinical information. Because scenario quality shapes reasoning and self-directed learning, this st...

Ultrasound assessment of diaphragm thickness and related determinants in healthy female adolescents: a retrospective study

The diaphragm plays a crucial role in respiration and is influenced by changes in body composition. However, data on the relationship between diaphragm thickness, respiratory muscle strength, and body composition in healthy adolescents are limited. This study aimed to investigate...

Emerging cfDNA technologies in glioblastoma through fragmentomics and sonobiopsy

Glioblastoma (GBM) is difficult to monitor using liquid biopsy because the tumor-derived fraction of circulating cell-free DNA (cfDNA), i.e., circulating tumor DNA (ctDNA), is often very low in plasma and because spatial and temporal heterogeneity complicate single-variant tracki...

Topic Modeling of Occupational Accident Narratives in the Manufacturing Sector Using BERTopic: Sector-Specific Accident Pattern Analysis

Despite technological developments and increasing awareness in the field of occupational health and safety, occupational accidents remain one of the fundamental problems that continue to have significant economic and social consequences. Particularly in the manufacturing sector,...

In Vivo Comparison of Laser Fluorescence, Near-Infrared Transillumination, and Conventional Methods for Approximal Caries Detection

Background/Objectives: The aim of this in vivo study was to compare the diagnostic performance of conventional methods, including visual examination according to the International Caries Detection and Assessment System II (ICDAS II) and digital bite-wing radiography, with laser f...

Beaconing detection via timing-based flow metadata analysis: implications for SCADA/ICS

Supervisory Control and Data Acquisition (SCADA) and Industrial Control Systems (ICS) are critical to the continuity of modern industrial infrastructure. Cyberattacks targeting these systems can lead to serious consequences, including production losses, physical damage, and threa...

Exploring Teacher Idealism: The Concentric Model, Narrative Identity, and Agency in English Language Teaching in Türkiye
