The genus , a group of ciliated protists, has attracted attention as a model organism due to its widespread distribution and ease of cultivation. This study examines the evolutionary patterns of the SSU rRNA secondary structure within this genus, aiming to elucidate its role in supporting evolutionary relationships and uncovering cryptic species. By predicting the secondary structure of SSU rRNA and applying the CBC (Compensatory Base Change) concept analysis, we examined 69 species of the genus , with 57 SSU rRNA gene sequences retrieved from GenBank and 12 newly sequenced specimens from South Korea.

Human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HPV-positive HNSCC) has distinct biological characteristics from HPV-negative HNSCC. Using an AI-based analytical platform on meta cohorts, we profiled expression patterns of viral transcripts and HPV viral genome integration, and classified the tumor microenvironment (TME). Unsupervised clustering analysis revealed five distinct and novel TME subtypes across patients (immune-enriched, highly immune and B-cell enriched, fibrotic, immune-desert, and immune-enriched luminal).

Aptamer-Conjugated Multi-Quantum Dot-Embedded Silica Nanoparticles for Lateral Flow Immunoassay.

Biosensors (Basel)

January 2025

Department of Bioscience and Biotechnology, Konkuk University, Seoul 05029, Republic of Korea.

Lateral flow immunoassays (LFIAs) are widely used for their low cost, simplicity, and rapid results; however, enhancing their reliability requires the meticulous selection of ligands and nanoparticles (NPs). SiO@QD@SiO (QD) nanoparticles, which consist of quantum dots (QDs) embedded in a silica (SiO) core and surrounded by an outer SiO shell, exhibit significantly higher fluorescence intensity (FI) compared to single QDs. In this study, we prepared QD@PEG@Aptamer, an aptamer conjugated with QD using succinimidyl-[(N-maleimidopropionamido)-hexaethyleneglycol]ester, which is 130 times brighter than single QDs, for detecting carbohydrate antigen (CA) 19-9 through LFIA.

Background: Anterior cruciate ligament (ACL) injuries are one of the most common sports injuries, accounting for approximately 50% of knee-related injuries. Extracorporeal shockwave therapy (ESWT), in the form of the radial (R-SWT) or focused shockwave (F-SWT), has been shown effective in treating various orthopaedic conditions. Recently, studies have investigated whether ESWT combined with standard rehabilitation may improve outcomes following anterior cruciate ligament reconstruction (ACLR).

χ-sepnet: Deep Neural Network for Magnetic Susceptibility Source Separation.

Hum Brain Mapp

February 2025

Laboratory for Imaging Science and Technology, Department of Electrical and Computer Engineering, Seoul National University, Seoul, Republic of Korea.

Magnetic susceptibility source separation (χ-separation), an advanced quantitative susceptibility mapping (QSM) method, enables the separate estimation of paramagnetic and diamagnetic susceptibility source distributions in the brain. Similar to QSM, it requires solving the ill-conditioned problem of dipole inversion, suffering from so-called streaking artifacts. Additionally, the method utilizes reversible transverse relaxation ( ) to complement frequency shift information for estimating susceptibility source concentrations, requiring time-consuming data acquisition for (e.

A multifactorial association study detected a probable causal connection between the prevalence of in the gut microbiome and the incidence of major depressive disorder (MDD) in the human host. A bioassay-guided fractionation approach identified bacterially produced metabolites that induced pro-inflammatory immune responses. The metabolites are unusual phospholipids that resemble conventional cardiolipins, in which diethanolamine (DEA) replaces the central glycerol.

Background And Purpose: This study investigates the practicality and utility of the "outline sign," which refers to the thin curvilinear hyperenhancing line that may be seen along the margin of a meningioma on a spin-echo postcontrast T1-weighted image. For cases in which the differential diagnosis may include other tumors, visualization of the outline sign may help to increase the diagnostic confidence for a meningioma. Therefore, in the temporal bone region such as the cerebellopontine angle or jugular foramen, where differential considerations may include a schwannoma or paraganglioma, we additionally investigated whether the outline sign may be observed in these nonmeningioma lesions.

Optimal timing and dosing of adjuvant cyclin-dependent kinase (CDK) 4/6 inhibitor in early breast cancer is controversial. This prospective phase II clinical trial investigated tolerability and safety of two ribociclib dosing schedules. Patients with stage I-III hormone receptor-positive (HR+)/HER2- breast cancer on adjuvant endocrine therapy (ET) were randomized to two ribociclib dosing schedules: 400 mg continuous vs 600 mg intermittent, with initiation in early (prior ET < 2 years) vs delayed (prior ET ≥ 2 years) setting.

Concerns have been raised that glucagon-like peptide 1 receptor agonists (GLP1-RAs) may increase the risk of thyroid cancer, but evidence remains conflicting. We therefore investigated if GLP1-RA use, compared with use of dipeptidyl peptidase-4 inhibitors (DPP-4is), was associated with thyroid cancer risk in patients with type 2 diabetes. This multisite cohort study with subsequent meta-analysis included six population-based databases from Canada (Ontario), Denmark, Norway, South Korea, Sweden, and Taiwan.

Coronary artery disease and percutaneous coronary intervention in patients with severe chronic kidney disease.

Department of Cardiology, St Francis Hospital and Heart Center, Roslyn, New York, USA; New York Institute of Technology, Old Westbury, New York, USA. Electronic address:

Coronary artery disease (CAD) is the leading cause of mortality among patients with chronic kidney disease (CKD), presenting unique challenges in diagnosis and management. Advanced CKD patients often present with atypical symptoms, and conventional diagnostic and interventional approaches carry risks, including contrast-induced nephropathy and the potential need for renal replacement therapy. These risks have led to the phenomenon of "renalism," where necessary procedures may be deferred due to concerns over renal injury.

Article Synopsis
  • High-dose methotrexate (MTX) can lead to serious complications like acute kidney injury (AKI), neutropenia, and liver damage, but glucarpidase, an enzyme that breaks down MTX, shows potential benefits.
  • In a study of 708 patients with MTX-AKI across 28 cancer centers, those receiving glucarpidase had a significantly higher chance of kidney recovery and faster recovery times compared to those who did not receive the treatment.
  • Additionally, glucarpidase treatment was associated with lower rates of severe neutropenia and liver enzyme elevation, but there was no notable difference in mortality rates between the two groups.

Otolaryngol Head Neck Surg

January 2025

Department of Otolaryngology-Head and Neck Surgery, Harvard Medical School, Boston, Massachusetts, USA.

As qualitative data analysis becomes more frequently applied within the fields of medicine and surgery, it is beneficial to expand our knowledge of the utility, methodology, and interpretation of these techniques. While qualitative research serves a distinct purpose and differs from quantitative research, both can be approached with diligence, with careful techniques that are similarly maintained and respected. In advance of this installment in the Evidence-Based Medicine in Otolaryngology series, we presented a comparison between qualitative and quantitative methods.
