Epigenetic Insights into Autism Spectrum Disorder: DNA Methylation Levels of , and in Korean Autism Spectrum Disorder Sibling Pairs.

Objective: Previous research on autism spectrum disorder (ASD) in Koreans has primarily focused on genetic diversity because of its high heritability. However, the emerging recognition of transgenerational epigenetic changes has recently shifted research attention towards epigenetic perspectives.

Methods: This study investigated the DNA methylation patterns of the promoter regions of candidate genes such as , , and in blood samples from ASD probands and their unaffected siblings.

Associations of mediterranean diet score and age-related macular degeneration in Korean elderly.

Background: Previous studies have reported associations between individual nutrients or specific foods and the risk of age-related macular degeneration (AMD). However, the relationship between overall dietary quality, specifically the alternative Mediterranean diet (aMED) score, and AMD remains unclear. Therefore, this study aimed to investigate the association between the aMED score, as an indicator of overall diet quality, and AMD in the Korean population.

Impact of graphical display on the intention to undergo risk-reducing salpingo-oophorectomy and mastectomy in individuals positive for BRCA pathogenic variant.

The BRCA1/2 pathogenic variant (PV) increases the risk of breast and ovarian cancer; thus, risk-reducing salpingo-oophorectomy (RRSO) and mastectomy (RRM) are recommended. We evaluated the effects of the graphical display of cancer risk compared with those of numerical presentation on the decision-making for risk-reducing (RR) surgery. A total of 471 women representing the Korean population were recruited.

Compressive Strength and Chloride Ion Penetration Resistance of GGBFS-Based Alkali-Activated Composites Containing Ferronickel Slag Aggregates.

Various studies have reported the use of alkali-activated composites to enable sustainable development in the construction industry as these composites eliminate the need for cement. However, few studies have used ferronickel slag aggregates (FSAs) as an aggregate material for alkali-activated composites. Alkali-activated composites are environmentally friendly and sustainable construction materials that can reduce carbon dioxide emissions from cement production, which accounts for 7% of global carbon emissions.

TongGuanWan Alleviates Doxorubicin- and Isoproterenol-Induced Cardiac Hypertrophy and Fibrosis by Modulating Apoptotic and Fibrotic Pathways.

Heart failure, a major public health issue, often stems from prolonged stress or damage to the heart muscle, leading to cardiac hypertrophy. This can progress to heart failure and other cardiovascular problems. Doxorubicin (DOX), a common chemotherapy drug, and isoproterenol (ISO), a β-adrenergic agonist, both induce cardiac hypertrophy through different mechanisms.

Ultrasonographic study and anatomical guidelines for botulinum neurotoxin injection into the parotid gland.

Benign enlargement of the parotid gland hypertrophy results in a bulky lateral facial contour and esthetic appearance. This study aimed to determine the depth from the skin surface to the parotid fascia, which encompasses the parotid gland. The anatomical properties of the parotid glands were evaluated in 40 patients using ultrasonography.

Four new species of Ashmead (Hymenoptera, Bethylidae) from Korea with an updated key to species in the Eastern Palaearctic region.

The genus Ashmead, 1893 (Hymenoptera, Bethylidae) is a cosmopolitan bethylid genus with 68 valid species distributed across most zoogeographic regions worldwide. This taxonomic study on Korean species of has led to the description of four new species, namely , , , and Additionally, illustrations of the diagnostic characteristics of each species are provided, along with an updated key for 11 species from the Eastern Palaearctic region.

Oral Extrusion of a Screw After Anterior Cervical Spine Plating: A Case Report.

Although anterior cervical discectomy and fusion (ACDF) is one of the most common surgical procedures performed for the treatment of cervical disease, it is associated with a variety of postoperative complications. Esophageal perforation is a rare but very serious post-ACDF complication, and cases in which screws extrude through the mouth are even rarer. Herein, we present the case of a 61-year-old woman who visited our emergency center with oral extrusion of a screw 6 months after undergoing ACDF.

Ethanolic Extract from (L.) Moench Inhibits Influenza A/B and Respiratory Syncytial Virus Infection : Preventive Agent for Viral Respiratory Infections.

Among the most frequent causes of respiratory infections in humans are influenza A virus H1N1 (H1N1), influenza B virus (IVB), and respiratory syncytial virus (RSV). Echinacea is a perennial wildflower belonging to the family. (L.

Performance of Large Language Models on the Korean Dental Licensing Examination: A Comparative Study.

Purpose: This study investigated the potential application of large language models (LLMs) in dental education and practice, with a focus on ChatGPT and Claude3-Opus. Using the Korean Dental Licensing Examination (KDLE) as a benchmark, we aimed to assess the capabilities of these models in the dental field.

Methods: This study evaluated three LLMs: GPT-3.

Geometric isomerization of dietary monounsaturated fatty acids by a cis/trans fatty acid isomerase from Pseudomonas putida KT2440.

Pseudomonas putida KT2440 encodes a defense system that rigidifies membranes by a cytochrome c-type cis/trans fatty acid isomerase (CTI). Despite its potential as an industrial biocatalyst for directly regulating the geometric isomerism of monounsaturated fatty acids, its original catalytic and structural properties have remained elusive. In this study, the catalytic nature of wild-type CTI purified P.

Development of eco-friendly pretreatment processes for high-purity silicon recovery from end-of-life photovoltaic modules.

This study examines the efficacy of photovoltaic (PV) recycling processes and technologies for the recovery of high-purity silicon powder from waste solar modules. In order to facilitate the simplification of complex processes, such as the conventional nitric acid dissolution, solvent and ultrasonic irradiation, and solvent dissolution, a variety of mechanical separation processes have been established. These processes are designed to enhance the efficiency and effectiveness of the aforementioned processes.
