Parabrachial CGRP neurons modulate active defensive behavior under a naturalistic threat.

Recent studies suggest that calcitonin gene-related peptide (CGRP) neurons in the parabrachial nucleus (PBN) represent aversive information and signal a general alarm to the forebrain. If CGRP neurons serve as a true general alarm, their activation would modulate both passive nad active defensive behaviors depending on the magnitude and context of the threat. However, most prior research has focused on the role of CGRP neurons in passive freezing responses, with limited exploration of their involvement in active defensive behaviors.

Resolution of hypertension after kidney transplantation is associated with improved kidney transplant outcomes: a nationwide cohort study.

Objectives: Patients with advanced chronic kidney disease suffer from hypertension, and kidney transplantation (KT) has potential to induce hypertension resolution. We hypothesized that hypertension resolution after KT is associated with better KT outcomes.

One-Step Synthesis of 2-Arylquinolin-4(1)-Ones from 1-(2-Aminoaryl)-3-Arylpropan-1-Ones via Pd(II)-Catalyzed Dehydrogenative Cyclization.

In this study, we developed palladium-catalyzed dehydrogenative cyclization to transform 1-(2-aminoaryl)-3-arylpropan-1-ones into 2-arylquinolin-4(1)-ones, also known as aza-flavones which are the bioisosteres of flavones, in an atom-economic manner. This method exhibited excellent chemical compatibility with a broad substrate scope, accommodating up to 25 derivatives. Additionally, kinetic studies were performed to elucidate the reaction mechanism.

Risk of Lung Cancer and Risk Factors of Lung Cancer in People Infected with Tuberculosis.

This study investigated lung cancer risk in people infected with tuberculosis (TB) compared to the general population and evaluated factors associated with lung cancer in TB-infected individuals. Mandatory reported TB infection case data in Gyeonggi Province, South Korea (2010 to 2016) were obtained and linked with medical usage and health screening data from the National Health Information Database. Lung cancer incidence in patients with TB was compared to that in the general population using standardized incidence ratio (SIR), adjusted for age and sex.

Non-canonical Function of Prolyl Hydroxylase Domain 2 in Breast Cancer Cell Growth and Progression: Role of Peptidyl-prolyl Cis-trans Isomerase NIMA-interacting 1.

Prolyl hydroxylase domain 2 (PHD2) is the primary oxygen sensing enzyme involved in hydroxylation of hypoxia-inducible factor (HIF). Under normoxic conditions, PHD2 hydroxylates specific proline residues in HIF-1α and HIF-2α, promoting their ubiquitination and subsequent proteasomal degradation. Although PHD2 activity decreases in hypoxia, notable residual activity persists, but its function in these conditions remains unclear Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (Pin1) targets proteins with phosphorylated serine/threonine-proline (pSer/Thr-Pro) motifs.

Relationship between Cancer Incidence and Health Behaviors from Ecological Study in Korea.

The aim of this ecological study was to examine the correlation between cancer incidence and health behaviors such as smoking, alcohol consumption, and obesity, and investigated whether there were differences in this correlation between metropolitan areas and other regions. Data on health behaviors exposure/prevalence and cancer incidence rates for 227 administrative districts (cities and counties) were obtained. The average exposure proportion measured annually from 2008 to 2011 in the Korea Community Health Survey data and the age-standardized cancer incidence data from 2014 to 2018, obtained through the cancer registry data, were downloaded from the Statistics Korea website.

Voxel-Based Morphometry and Subfield Volumetry Analysis Reveal Limbic System Involvement in Tinnitus.

Background And Purpose: Tinnitus is a condition in which individuals perceive sounds, such as ringing or buzzing, without any external source. Although the exact cause is not fully understood, recent studies have indicated the involvement of nonauditory brain structures, including the limbic system. We aimed to compare the volumes of specific brain structures between patients with tinnitus and controls.

Antipsychotic continuation during pregnancy and risk of postpartum relapse in women with schizophrenia: nationwide register-based study.

Background: Women with schizophrenia frequently discontinue antipsychotic medications during pregnancy. However, evidence on the risk of postpartum relapse associated with antipsychotic use during pregnancy is lacking.

Aims: To investigate the within-individual association between antipsychotic continuation during pregnancy and postpartum relapse in women with schizophrenia.

Secreted LGALS3BP facilitates distant metastasis of breast cancer.

Background: Patients with estrogen receptor (ER)-positive breast cancer (BC) can be treated with endocrine therapy targeting ER, however, metastatic recurrence occurs in 25% of the patients who have initially been treated. Secreted proteins from tumors play important roles in cancer metastasis but previous methods for isolating secretory proteins had limitations in identifying novel targets.

Methods: We applied an in situ secretory protein labeling technique using TurboID to analyze secretome from tamoxifen-resistant (TAMR) BC.

A robust multimodal brain MRI-based diagnostic model for migraine: validation across different migraine phases and longitudinal follow-up data.

Inter-individual variability in symptoms and the dynamic nature of brain pathophysiology present significant challenges in constructing a robust diagnostic model for migraine. In this study, we aimed to integrate different types of magnetic resonance imaging (MRI), providing structural and functional information, and develop a robust machine learning model that classifies migraine patients from healthy controls by testing multiple combinations of hyperparameters to ensure stability across different migraine phases and longitudinally repeated data. Specifically, we constructed a diagnostic model to classify patients with episodic migraine from healthy controls, and validated its performance across ictal and interictal phases, as well as in a longitudinal setting.

Purpose: In the INBUILD trial in patients with progressive pulmonary fibrosis (PPF), nintedanib slowed the decline in forced vital capacity (FVC) versus placebo, with a safety profile characterised mainly by gastrointestinal events. INBUILD-ON, the open-label extension of INBUILD, assessed the safety of nintedanib during longer-term treatment. Data on FVC were collected.

Standardized patient profile review using large language models for case adjudication in observational research.

Using administrative claims and electronic health records for observational studies is common but challenging due to data limitations. Researchers rely on phenotype algorithms, requiring labor-intensive chart reviews for validation. This study investigates whether case adjudication using the previously introduced Knowledge-Enhanced Electronic Profile Review (KEEPER) system with large language models (LLMs) is feasible and could serve as a viable alternative to manual chart review.

Comparison of coseismic velocity changes estimated by cross-correlation of ambient seismic noise for earthquakes in south Korea and Japan.

Ambient noise cross-correlation has been widely used to observe post-earthquake temporal velocity variations. Comparative studies are essential for assessing seismic hazards and clarifying the relationship between velocity variation and magnitude. However, very few comparative studies by earthquake magnitude have been conducted, particularly for magnitudes smaller than 6.

Direct View of Gate-Tunable Miniband Dispersion in Graphene Superlattices Near the Magic Twist Angle.

Superlattices from twisted graphene mono- and bilayer systems give rise to on-demand many-body states such as Mott insulators and unconventional superconductors. These phenomena are ascribed to a combination of flat bands and strong Coulomb interactions. However, a comprehensive understanding is lacking because the low-energy band structure strongly changes when an electric field is applied to vary the electron filling.

Association of Post-procedure Ankle-Brachial Index with Outcomes Following Drug-Coated Balloon Angioplasty in Femoropopliteal Artery Disease.

Endovascular treatment of femoropopliteal artery (FPA) disease with Drug-coated balloons (DCBs) may face complications such as arterial recoil, dissection, and residual stenosis. Angiography has limited accuracy for evaluating blood flow through revascularized target lesions. Thus, there is a need for post-procedure hemodynamic assessment in treated limbs.
