Importance: Down syndrome, resulting from trisomy 21, is the most prevalent chromosomal disorder and a leading cause of intellectual disability. Despite its significant impact on brain development, research on the white matter microstructure in infants with Down syndrome remains limited.

Objective: To investigate early white matter microstructure in infants with Down syndrome using diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI).

Background: The benefits of early detection in medullary thyroid carcinoma (MTC) are not well established. This study investigates the impact of early detection of MTC on clinical outcomes.

Methods: This retrospective study evaluated 144 patients diagnosed with MTC at Samsung Medical Center between 1995 and 2019, classified as asymptomatic (mostly detected through routine health check-ups, including ultrasonography, calcitonin, or carcinoembryonic antigen levels) and symptomatic.

Objectives: Caring for ill cancer patients imposes a considerable burden on families, significantly reducing quality of life (QoL). This study examined the association between death preparation and QoL amongst family caregivers (FCs) of terminally ill patients with cancer in South Korea.

Materials And Methods: A multicentre cross-sectional survey using questionnaires was conducted in nine inpatient palliative care units in South Korea.

Aging is considered the contributory accumulation of abruptions occurring through cell signaling cascades, which ultimately cause changes in physical functions, cell fate, and damage across all organ systems. DNA damage response (DDR) also occurs through telomere shortening, tumor formation, mitochondrial dysfunction, and so forth. Cellular aging occurs through cell cycle arrest, which is the result of extended DDR cascade signaling networks via MDC1, 53BP1, H2AX, ATM, ARF, P53, P13-Akt, BRAF, Sirtuins, NAD + , and so forth.

Background: We aimed to investigate the prognostic significance of primary tumor size in patients with pT1-T3a N0 M0 papillary thyroid carcinoma (PTC), minimizing the impact of confounding factors.

Methods: A multicenter retrospective study included 5,759 patients with PTC. Those with lymph node metastasis, gross extrathyroidal extension (ETE), and aggressive variants were excluded.

Hereditary retinoblastoma is a classic cancer predisposition syndrome with risks beginning in early infancy. About 45% of children with retinoblastoma (RB) have hereditary disease. These children are at risk for both intraocular disease as well as additional neoplasms throughout their lifetime.

Background: The combination of atezolizumab with etoposide and carboplatin (AECb) has become a new standard of care for extensive-stage small-cell lung cancer (ES-SCLC). This study evaluates its impact on central nervous system (CNS) progression, specifically brain metastases.

Method: We analyzed the outcomes of 550 ES-SCLC patients who received first-line therapy between 2016 and 2022, focusing on time to intracranial progression (TTicP), progression-free survival (PFS), and overall survival (OS).

Goniomonads are commonly found heterotrophic biflagellates in both marine and freshwater environments. Despite the high genetic diversity inferred from 18S rDNA data, many goniomonad species remain undescribed. In this study, we established a total of 21 marine goniomonad culture strains, and from these, describe three new species by using 18S rDNA phylogeny, light microscopy, and electron microscopy.

Human induced pluripotent stem cell (iPSC) derived cortical organoids (hCOs) model neurogenesis on an individual's genetic background. The degree to which hCO phenotypes recapitulate the brain growth of the participants from which they were derived is not well established. We generated up to 3 iPSC clones from each of 18 participants in the Infant Brain Imaging Study, who have undergone longitudinal brain imaging during infancy.

RAS/MAPK pathway mutations often induce RASopathies with overlapping features, such as craniofacial dysmorphology, cardiovascular defects, dermatologic abnormalities, and intellectual disabilities. Although BRAF gene mutations are associated with cardio-facio-cutaneous (CFC) syndrome and Noonan syndrome, it remains unclear how these mutations impair cognition. Here, we investigated the underlying neural mechanisms using several mouse models harboring a gain-of-function BRAF mutation (K499E) discovered in RASopathy patients.

Pain management remains a major challenge in the healthcare system. While synthetic analgesics are widely used for pain management, their effectiveness in managing chronic pain is often limited due to low efficacy or side effects. Thus, there is growing interest in exploring alternative pain relief methods, particularly using medicinal plants from traditional Eastern medicine and their phytochemicals.

Steatotic liver enhances liver metastasis of colorectal cancer, but this process is not fully understood. Steatotic liver induced by a high-fat diet (HFD) increases cancer-associated fibroblast (CAF) infiltration and collagen and hyaluronic acid (HA) production. We investigated the role of HA synthase 2 (HAS2) in the fibrotic tumor microenvironment in steatotic liver using Has2ΔHSC mice, in which Has2 is deleted from hepatic stellate cells.

Memristors are promising candidates for next-generation non-volatile memory devices, offering low power consumption and high-speed switching capabilities. However, conventional metal oxide-based memristors are constrained by fabrication complexity and high costs, limiting their commercial viability. Organic-inorganic hybrid perovskites (OIHPs), known for their facile solution processability and unique ionic-electronic conductivity, provide an attractive alternative.

Purpose: Antipsychotic drugs (APDs) can be used to relieve psychological symptoms in patients with cancer. We investigated the nationwide use of APDs during concurrent chemoradiotherapy (CCRT) for patients with lung cancer and its association with overall survival (OS).

Materials And Methods: The National Health Service database was used in this retrospective cohort study.

Introduction: Drug-induced liver injury (DILI) has been investigated at the patient level. Analysis of gene perturbation at the cellular level can help better characterize biological mechanisms of hepatotoxicity. Despite accumulating drug-induced transcriptome data such as LINCS, analyzing such transcriptome data upon drug treatment is a challenging task because the perturbation of expression is dose and time dependent.

Schizophrenia and attention deficit hyperactivity disorder (ADHD) have many contradicting features, but both these disorders share inattention as a core symptom. This study explored how the characteristics of inattention differ between the two disorders. 20 patients with schizophrenia, 20 patients with adult ADHD and 20 healthy controls participated in this study.

Even in antiretroviral therapy (ART)-suppressed human immunodeficiency virus (HIV)-infected individuals, there are heterogeneous populations of HIV-expressing cells exhibiting variable degrees of progression through blocks to HIV transcriptional initiation, elongation, completion, and splicing. These HIV-transcribing cells likely contribute to HIV-associated immune activation and inflammation as well as the viral rebound that occurs after stopping ART. However, it is unclear whether the blocks to HIV transcription are present before ART and how the timing and duration of ART may affect the clearance of cells expressing HIV transcripts that differ in their processivity and/or presence of mutations.
