Article Synopsis
  • Whole-genome sequencing (WGS) of Korean autism families reveals that autistic females have a higher genetic burden than males, indicating a higher liability threshold for females compared to males across different ancestries.
  • The study analyzes data from a large sample of Korean individuals and compares it with European ancestry cohorts, finding that sex differences in genetic burden and autism symptoms vary significantly.
  • Results show that while females carry more damaging genetic variants, male siblings of autistic females display more severe social communication issues, highlighting the complexity of autism's genetic factors and the influence of sex on autistic traits.

This article explores the role of sensorimotor engagement in students' learning of a challenging science, technology, engineering, and math-related concept. Previous research has failed to distinguish two features commonly associated with embodiment: sensorimotor engagement and visuospatial concreteness. In the current research, we ask whether sensorimotor engagement-operationalized as watching a video of hands manipulating paper representations-offers unique benefits beyond the visuospatial concreteness of a dynamic visualization of the same process.

Background: Lung cancer, especially non-small cell lung cancer (NSCLC), poses a significant health challenge globally due to its high mortality. Afatinib, a second-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI), has shown superior efficacy over traditional chemotherapy in NSCLC treatment. However, issues like secondary resistance and adverse effects call for alternative therapies.

Fine particulate matter (PM) is a risk factor for pulmonary diseases and lung cancer, and inhaled PM is mainly deposited in the bronchial epithelium. In this study, we investigated the effect of long-term exposure to low-dose PM on BEAS-2B cells derived from the normal bronchial epithelium. BEAS-2B cells chronically exposed to a concentration of 5 µg/ml PM for 30 passages displayed the phenotype promoting epithelial-mesenchymal transition (EMT) and cell invasion.

Peptidoglycan (PG) is an important architectural element that imparts physical toughness and rigidity to the bacterial envelope. It is also a dynamic structure that undergoes continuous turnover or autolysis. possesses redundant PG degradation enzymes responsible for PG turnover; however, the advantage afforded by the existence of numerous PG degradation enzymes remains incompletely understood.

Aim: Short tandem repeats (STRs) are repetitive DNA sequences and highly mutable in various human disorders. While the involvement of STRs in various genetic disorders has been extensively studied, their role in autism spectrum disorder (ASD) remains largely unexplored. In this study, we aimed to investigate genetic association of STR expansions with ASD using whole genome sequencing (WGS) and identify risk loci associated with ASD phenotypes.

Purpose: We aimed to describe RAS mutations in gynecologic cancers as they relate to clinicopathologic and genomic features, survival, and therapeutic implications.

Experimental Design: Gynecologic cancers with available somatic molecular profiling data at our institution between February 2010 and August 2022 were included and grouped by RAS mutation status. Overall survival was estimated by the Kaplan-Meier method, and multivariable analysis was performed using the Cox proportional hazard model.

Bronchoscopy is a frequently used initial diagnostic procedure for patients with suspected lung cancer (LC). Cytological examinations of bronchial washing (BW) samples obtained during bronchoscopy often yield inconclusive results regarding LC diagnosis. The present study aimed to identify molecular biomarkers as a non-invasive method for LC diagnosis.

Understanding normal probability distributions is a crucial objective in mathematics and statistics education. Drawing upon cognitive psychology research, this study explores the use of drawings and visualizations as effective scaffolds to enhance students' comprehension. Although much research has documented the helpfulness of drawing as a research tool to reveal students' knowledge states, its direct utility in advancing higher-order cognitive processes remains understudied.

Article Synopsis
  • This study focuses on improving lung cancer diagnosis through a new test that analyzes DNA methylation from bronchial washing cytology, which has shown better sensitivity compared to traditional bronchoscopy methods.
  • Researchers enrolled 187 patients with suspicious CT lesions and performed tests on two specific methylation biomarkers, revealing that the combination of both tests increased diagnostic sensitivity.
  • The findings suggest that using DNA methylation analysis could potentially reduce the need for invasive procedures like biopsies in detecting lung cancer.

Large old trees, which provide ecosystem services and serve as a historical and cultural heritage, are exposed to various environmental threats, such as habitat fragmentation and climate change, necessitating diagnosis of tangible and intangible stresses and their effects on tree growth for effective management. This study investigated the photosynthetic characteristics of 25 large old Zelkova serrata (Thunb.) Makino trees in Chungcheong Province, Korea, and identified the physical environmental factors affecting their physiological responses.

Objective: This study aims to determine the optimal dose of recombinant-human bone morphogenic protein-2 (rhBMP-2) for successful bone fusion in minimally invasive lateral lumbar interbody fusion (MIS LLIF). Previous studies show that rhBMP is an effective alternative to autologous iliac crest bone graft, but the optimal dose remains uncertain. The study analyzes the fusion rates associated with different rhBMP doses to provide a recommendation for the optimal dose in MIS LLIF.

  • * The study identifies the cell surface protein Lrig1 as a key factor in enhancing the suppressive abilities of Tregs, particularly in T helper (Th) 17 cells.
  • * Lrig1 deficiency leads to weakened suppressive functions but does not stop the differentiation of naïve T cells; targeting Lrig1 could be a potential therapeutic strategy for autoimmune diseases, as shown by improved outcomes in mouse models.

Using multiple representations is an important part of learning and problem-solving in science, technology, engineering and mathematics fields. For students to acquire flexible knowledge of representations, they must attend to the structural information within each representation and practice making relational connections between representations. Most studies so far have only attempted to help students connect between multiple representations in the lab or short-term classroom interventions, with the intervention largely separated from students' authentic learning.

Peptidoglycan (PG) is an essential bacterial architecture pivotal for shape maintenance and adaptation to osmotic stress. Although PG synthesis and modification are tightly regulated under harsh environmental stresses, few related mechanisms have been investigated. In this study, we aimed to investigate the coordinated and distinct roles of the PG dd-carboxypeptidases (DD-CPases) DacC and DacA in cell growth under alkaline and salt stresses and shape maintenance in Escherichia coli.

  • Cancer stem cells (CSCs) in lung cancer resist therapies like chemotherapy and radiation, highlighting the need for targeted treatment strategies.
  • Recent research indicates that down-regulation of miR-26a-5p is linked to the mesenchymal-like characteristics of lung cancer cells, potentially influencing the CSC phenotype.
  • Increasing miR-26a-5p levels can reduce cancer cell growth and enhance the effectiveness of chemotherapy, suggesting it could be a promising target for improving lung cancer treatments and patient survival.
