Automated Screening of Precancerous Cervical Cells Through Contrastive Self-Supervised Learning.

Cervical cancer is a significant health challenge, yet it can be effectively prevented through early detection. Cytology-based screening is critical for identifying cancerous and precancerous lesions; however, the process is labor-intensive and reliant on trained experts to scan through hundreds of thousands of mostly normal cells. To address these challenges, we propose a novel distribution-augmented approach using contrastive self-supervised learning for detecting abnormal squamous cervical cells from cytological images.

This study aimed to investigate the prevalence of such discrepancies during care transitions and their impact on post-discharge emergency department (ED) visits in this patient population.

Methods: This retrospective cross-sectional study included patients aged 65 and older who were on chronic medications and admitted to the intensive care units of emergency departments (ED-ICUs) between 2019 and 2020.

Heat-treated brown rice starch structure and effect on short-chain fatty acids and mouse intestinal microbiota.

Rice with high resistant starch (RS) exhibits the potential to improve glucose metabolism, insulin sensitivity. In this study, using two rice varieties-Samgwang, a medium-amylose rice, and Dodamssal, a high-amylose rice containing RS-we analyzed the composition and molecular structural characteristics of brown rice and its starch and the effects on fasting blood glucose levels, fecal short-chain fatty acid (SCFA), and gut microbiota after 8 weeks of consumption in mice. The amylose content of heat-treated Samgwang (HS) and -Dodamssal (HD) was 21.

STK19 facilitates the clearance of lesion-stalled RNAPII during transcription-coupled DNA repair.

Transcription-coupled DNA repair (TCR) removes bulky DNA lesions impeding RNA polymerase II (RNAPII) transcription. Recent studies have outlined the stepwise assembly of TCR factors CSB, CSA, UVSSA, and transcription factor IIH (TFIIH) around lesion-stalled RNAPII. However, the mechanism and factors required for the transition to downstream repair steps, including RNAPII removal to provide repair proteins access to the DNA lesion, remain unclear.

Widely Integrated Services in Home (WISH) for homebound older adults: a study protocol for a randomized encouragement trial.

Background: Home-based primary care (HBPC) is an emerging patient-centered, interprofessional healthcare service model that can address unmet medical needs and care burdens for homebound older adults. In December 2022, the Ministry of Health and Welfare in South Korea launched the Home-Based Medical Center Demonstration project to provide a new bundle payment for physician home visits. In this study, we seek to determine whether the recently introduced HBPC services in South Korea have been associated with a reduction in long-term care (LTC) facility admissions and acute hospitalizations among homebound older adults.

Cisplatin induces kidney damage through the down-regulation of Prx I by autophagic degradation.

In this study, we investigated the potential role of PrxI in cis-diamminedichloroplatinum (cisplatin)-induced renal damage in mice. The anticancer drug cisplatin is a chemotherapeutic agent that is widely used to treat solid tumors. Cisplatin-induced nephrotoxicity is a serious dose-limiting side effect, primarily caused by oxidative stress.

Raising the Academic Authority of Clinical Experience: The Department of Internal Medicine at Keijo Imperial University and Its Periodical Imsangnaegwahak.

This paper examines the periodical Clinical Internal Medicine published by the Department of Internal Medicine at Keijo Imperial University in colonial Korea. Previous studies on medical research at Keijo Imperial University have primarily focused on preclinical departments such as anatomy, hygiene, pharmacology, and microbiology which produced knowledge that supported Japan's imperialistic expansion. This approach has overlooked the research contributions of clinical departments, often viewing the roles of preclinical and clinical departments through a dichotomy between research versus clinician training.

Crystal Structure and Molecular Mechanism of Isocitrate Lyase from .

is a green, nonsulfur bacterium that employs the 3-hydroxypropionate cycle to grow, using carbon dioxide/bicarbonate as its primary carbon source. Like most bacteria, it possesses the glyoxylate cycle, facilitated by malate synthase and isocitrate lyase (ICL), allowing a "tricarboxylic acid cycle" bypass. also harbors ICL, an enzyme that catalyzes reversible isocitrate cleavage into glyoxylate and succinate.

Community-Based Exercise Programs Post Spinal Cord Injury Hospitalization: A Pilot Study for a Randomized, Multicenter, Double-Blind Controlled Setting.

This study explores the effectiveness of community-based exercise programs for individuals with spinal cord injury (SCI) following hospital discharge. Given the rising incidence of SCI, particularly in South Korea, and the associated long-term disabilities, the necessity for comprehensive post-discharge rehabilitation is paramount. The study focuses on a pilot randomized multicenter double-blind controlled trial, targeting SCI patients who have completed inpatient rehabilitation and are living in the community.

Will you boost my joy or dampen it? Cultural differences in hedonic interpersonal emotion regulation in romantic relationships.

A central tenet guiding contemporary research on emotions is that people are fundamentally motivated to feel good and avoid feeling bad. This principle translates from intrapersonal to extrinsic interpersonal emotion regulation; people not only strive to achieve the hedonic goal of managing their own emotions, but they also help others reach the same goal-the process called hedonic interpersonal emotion regulation (hedonic IER). Here, we challenge the centrality of this principle in romantic relationships by testing a hypothesis that, compared with European Americans, Asians use hedonic IER less and benefit less from their partners' use of this strategy.

Mortality risk of loneliness: Culture matters.

Objective: Does loneliness predict premature death? Much prior research suggests so, but this evidence draws primarily on populations from individualistic societies, such as North America and Western Europe. Here, we aimed to extend this evidence by testing a hypothesis that loneliness would predict greater mortality risk in collectivistic societies, where social interdependence is normatively sanctioned.

Method: Using a harmonized dataset from two individualistic (England and the United States) and two collectivistic (Korea and Mexico) countries (combined = 41,869), we tested whether cultural contexts moderate the extent to which loneliness predicts 10-year all-cause mortality.

Development of semi-dried goat meat jerky using tenderizers considering the preferences of the elderly.

Elderly people avoid eating red meat and dried meat product due to its texture and stiffness; they deprive them of rich sources of nutrients. In addition, food-related diseases are exponentially increasing due to using synthetic additives in food products. Therefore, this research aimed to develop semi-dried goat meat jerky considering geriatric preferences by using natural tenderizers and nitrate.

Heartbeat-related spectral perturbation of electroencephalogram reflects dynamic interoceptive attention states in the trial-by-trial classification analysis.

Attending to heartbeats for interoceptive awareness initiates distinct electrophysiological responses synchronized with the R-peaks of an electrocardiogram (ECG), such as the heartbeat-evoked potential (HEP). Beyond HEP, this study proposes heartbeat-related spectral perturbation (HRSP), a time-frequency map of the R-peak locked electroencephalogram (EEG), and explores its characteristics in identifying interoceptive attention states using a classification approach. HRSPs of EEG brain components specified by independent component analysis (ICA) were used for the offline and online classification of interoceptive states.

Pilot Study of Home-Based Virtual Reality Fitness Training in Post-Discharge Rehabilitation for Patients with Spinal Cord Injury: A Randomized Double-Blind Multicenter Trial.

Spinal cord injury (SCI) patients require continuous rehabilitation post-discharge to ensure optimal recovery. This study investigates the effectiveness of home-based virtual reality fitness training (VRFT) as a convenient and accessible rehabilitation method for SCI patients. This randomized, double-blind, multicenter trial will enroll 120 participants, assigning them to either an 8-week VRFT program (exercise group) or a control group engaging in regular daily activities.

Effects of perceived risk of COVID-19 on fear among visiting workers: Mediating role of perceived stress.

With the creation of a social distancing policy due to coronavirus disease 2019 (COVID-19), home visit workers are under mental stress as they are treated as the source of infection for COVID-19. Since door-to-door rental equipment examiners and gas inspectors must perform their duties even in the COVID-19 situation, they are being discriminated against so severely. The purpose of study was to examine the mediating role of perceived stress on the relationship between risk perception and fear.

Effects of gender and slaughter age on physicochemical and quality traits of Korean Hanwoo striploin.

Hanwoo beef is in high demand because of its unique flavor, freshness, and high-fat content. However, the longer rearing period required to enhance marbling in Hanwoo cattle has adverse environmental consequences, such as greenhouse gas emissions and overall rearing costs. To address consumer preferences for leaner and healthier meat, the Korean meat industry has recently introduced Hanwoo heifer meat as an alternative source, but its quality traits are still unclear.
