Seventy-six treatment-naive human immunodeficiency virus (HIV)-1-infected patients were recruited from Korea and China to evaluate transmitted drug resistance (TDR). Although no major TDR was observed within the study population, some resistance-associated mutations in the reverse transcriptase region were observed (V118I 9.2%, V179D 7.9%). The frequencies of resistance-associated mutations in NNRTI (V179D) and PI minor mutations were higher in Korean patients compared with Chinese patients (13.6% vs. 0%, 45.5% vs. 12.5%, p < 0.05). Although unique clustering was observed in phylogenetic analyses according to geographic sources, cautious monitoring is recommended due to increasing TDR reports in this area where the population shares close geographic and cultural aspects.

Anorexia nervosa (AN) is a severe psychiatric disorder, characterized by restricted eating, fear to gain weight, and a distorted body image. Mu-opioid receptor (MOR) functions as a part of complex opioid system and supports both homeostatic and hedonic control of eating behavior. Thirteen patients with AN and thirteen healthy controls (HC) were included in this study.

Background: Sample preparation can be a critical stage of analytical procedures that profoundly influences their performance, environmental impact, and overall efficiency. While nanomaterials have revolutionized sample preparation owing to their high surface area-to-volume ratios, tunable surface chemistry, and enhanced adsorption capacities, limitations persist. Researchers have ushered in a new era of efficient sample preparation methodologies that could overcome the limitations of nanomaterials by introducing deep eutectic solvents (DESs), which have unique advantages such as low volatility and toxicity, biodegradability, and tunability.

Wastewater treatment systems are essential for sustainable water resource management but face challenges such as equipment and sensor malfunctions, fluctuating influent conditions, and operational disturbances that compromise process stability and detection accuracy. To address these challenges, this paper systematically reviews data-driven fault detection and diagnosis (FDD) methods applied in wastewater treatment systems from 2014 to 2024, focusing on their applications, advancements, and limitations. Main contributions include an overview of key treatment processes, a detailed evaluation of fault types (process and sensor faults), advancements in multivariate statistical methods, machine learning (ML), and hybrid FDD techniques, as well as their effectiveness in anomaly detection, managing complex data distributions, and enabling real-time monitoring.
