Clinical spectrum of adult-onset leukoencephalopathy with axonal spheroids and pigmented glia in individuals of Korean ancestry.

Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a rare white matter disease characterized by axonal and glial injury. Although its clinical characteristics have been described in case reports, the prevalence of CSF1R mutations in clinically suspected ALSP cases remains unclear. Herein, we analysed the frequency of CSF1R mutations in patients with probable or possible ALSP and describe the genetic, clinical, radiological, and pathological findings of ALSP cases in individuals of Korean ancestry.

Diet therapy abates mutant APC and KRas effects by reshaping plasma membrane cholesterol nanodomains.

Cholesterol-enriched plasma membrane domains are known to serve as signaling platforms in a diverse array of cellular processes. However, the link between cholesterol homeostasis and mutant APC-KRas-associated colorectal tumorigenesis remains to be established. Thus, we investigated the impact of Apc-Kras on (i) colonocyte plasma membrane cholesterol homeostasis, order, and receptor nanoclustering, (ii) colonocyte cell proliferation, and (iii) whether these effects are modulated by select membrane active dietaries (MADs).

Linguistic characteristics of primary progressive aphasia in a verb-final language.

Purpose: The current study aimed to examine the linguistic characteristics of Korean-speaking individuals diagnosed with primary progressive aphasia(PPA).

Methods: Two individuals with agrammatic/non-fluent variants of nfvPPA and two with semantic variants of svPPA participated in this study. Picture description tasks were used to collect connected speech samples.

Analysis of Binding Sites for a Novel ssDNA Aptamer Specific to Verrucarin A and Detection in Dust Extracts.

An aptamer is a single-stranded oligonucleotide that serves as a chemical antibody with a high specificity and binding affinity that can recognize a wide range of molecules. Effective modification and truncation of aptamers can enhance their binding affinities to particular targets while also broadening their application for uses, such as biosensors. However, a conventional trial-and-error methodology hinders this process.

Association between osteoporosis and the rate of telomere shortening.

A shorter leukocyte telomere length (LTL) is reported to be associated with age-related diseases, including osteoporosis. Many studies have tried identifying the association between LTL and osteoporosis, although it remains controversial. This study aimed to determine whether osteoporosis is independently associated with LTL shortening in a prospective longitudinal cohort.

Evaluating the effects of action learning on the research competency of undergraduate nursing students: A mixed-methods study.

Background: Research skills in nursing are crucial for guiding evidence-based practice and enhancing health care. However, undergraduate nursing students often encounter challenges in skill development because of curriculum constraints that prioritize clinical education. Bridging this skill gap is imperative for preparing students for evidence-based practice and nursing scholarship.

Tumor antigen PRAME is a potential therapeutic target of p53 activation in melanoma cells.

Upregulation of PRAME (preferentially expressed antigen of melanoma) has been implicated in the progression of a variety of cancers, including melanoma. The tumor suppressor p53 is a transcriptional regulator that mediates cell cycle arrest and apoptosis in response to stress signals. Here, we report that PRAME is a novel repressive target of p53.

Comparison of Enlarged Perivascular Spaces in Early-Onset and Late-Onset Alzheimer Disease-related Cognitive Impairment: A Single Clinic-based Study in South Korea.

We examined whether there were differences in the presence of centrum semiovale-enlarged perivascular spaces (CSO-ePVS) and basal ganglia-ePVS (BG-ePVS) among patients with Alzheimer disease-related cognitive impairment (ADCI) based on their age of onset. Out of a total of 239 patients with cognitive impairment, 155 with positive amyloid-PET results were included. Among these, 43 had early-onset ADCI (EOADCI) and 112 had late-onset ADCI (LOADCI).

Effect of Dietary Habits on Alzheimer's Disease Progression.

Purpose: Research on the relationship between diet and dementia among Koreans are lacking. This study investigated the association between dietary habits and dementia progression over 3 years in patients with Alzheimer's disease dementia (ADD).

Materials And Methods: This study included 705 patients with mild-to-moderate ADD.

Case report: Neuronal intranuclear inclusion disease initially mimicking reversible cerebral vasoconstriction syndrome: serial neuroimaging findings during an 11-year follow-up.

Neuronal intranuclear inclusion disease (NIID) is a rare, progressive neurodegenerative disorder known for its diverse clinical manifestations. Although episodic neurogenic events can be associated with NIID, no reported cases have demonstrated concurrent clinical features or MRI findings resembling reversible cerebral vasoconstriction syndrome (RCVS). Here, we present the inaugural case of an adult-onset NIID patient who initially displayed symptoms reminiscent of RCVS.

Classifying Studies on Workplace Violence for Visiting Nurses Using the Social-Ecological Model: A Scoping Review.

Purpose: To prevent workplace violence (WV) against visiting nurses (VNs), understanding the influencing factors is crucial. To better comprehend potential violence prevention strategies, the U.S.

Monitoring and evaluation of provincial classical swine fever immunization implementation with an E2 subunit vaccine in Jeju Island, South Korea.

Purpose: Accidental vaccination with a live attenuated low-virulence strain of Miyagi (LOM) vaccine led to the reemergence of classical swine fever virus (CSFV) in Jeju province, South Korea in 2014. To control the continual outbreaks of LOM-derived CSFV, the provincial government launched a provincial mass vaccination project using a CSF-E2 subunit vaccine. We conducted this study to assess the herd immunity level and outcomes of E2 vaccine-based immunization in breeding and growing herds on Jeju Island during 2020-2021.

Advancing ecological validity and clinical utility in virtual reality-based continuous performance test: exploring the effects of task difficulty and environmental distractors.

Introduction: Researchers have highlighted concerns regarding the limited diagnostic utility and ecological validity of the Continuous Performance Test (CPT). Recent advancements in VR-based CPTs have attempted to address these concerns by simulating real-life scenarios and enhancing attention deficit hyperactivity disorder (ADHD) diagnosis; however, certain areas require improvement for obtaining reliable data from both healthy individuals and those with ADHD. To tackle these issues, we developed an enhanced VR-based CPT program featuring four distinct difficulty levels, advancing toward home-based assessment.

Influence of short-lived radioiodines other than 131I on screening direct thyroid measurements with TCS-172 NAI(TL) survey meters.

In a nuclear emergency, one of the actions taken for the sake of public is to monitor thyroid exposure to radioiodines. Japan's Nuclear Regulation Authority recently published a report on such monitoring and proposed direct thyroid measurements with conventional NaI(Tl) survey meters (e.g.

Palmar-plantar erythrodysesthesia syndrome resulting from toceranib phosphate in a dog with apocrine gland anal sac adenocarcinoma: a case report.

An 11-year-old neutered male Miniature Poodle with a stage 3 apocrine gland adenocarcinoma was started on chemotherapy with toceranib phosphate after surgery. Beginning on day 10 of toceranib, the dog's foot pads became erythematous and hyperkeratinized. The dog complained of pain, inability to walk, depression, and loss of appetite.
