Limited fashion products serve as a strategy for demonstrating the brand’s vitality and presence by satisfying the emotional needs of consumers seeking to escape from the boredom of similar products. The MZ generation values unique experiences and desires to purchase rare and unique products. Accordingly, the fashion industry prioritizes launching limited fashion products that emphasize artistry and can convey different values compared to existing products. The open-run phenomenon, characterized by people waiting in line before the store opens and then running to the store to purchase these limited products as soon as the store opens, is rapidly emerging as a consumer trend in our society. This study explored the impact of fashion consumers’ psychological factors-that is, FOMO, brand attachment, and need for uniqueness-on their open-run intention for limited fashion products. An online survey was administered to test the research hypotheses on Korean consumers, and 300 responses were statistically analyzed using the SPSS 28.0 program. The results revealed that FOMO, brand attachment, and the need for uniqueness significantly increased open-run intention for limited fashion products. Furthermore, consumers’ fashion involvement appeared to have a significant positive moderating effect on FOMO, brand attachment, and open-run intention. However, it did not substantially impact the effect of the need for uniqueness on open-run intention.

Cucumber mosaic virus (CMV) poses a considerable threat to a diverse array of crops in global agriculture. CMV impacts commercially important cut lilies by diminishing both yield and flower quality. We used RNA sequencing (RNA-seq) to investigate the changes in gene expression in the leaves and bulbs of four distinct cultivars of cut lily, ‘Cancun,’ ‘Brunello,’ ‘Connecticut King,’ and ‘Casa Blanca’ following CMV infection. Notably, CMV affected photosynthetic processes by significantly downregulating genes associated with photosynthesis. In addition, CMV infection was detrimental to chloroplast function and energy production. We observed differential expression of genes associated with both dominant and recessive resistance pathways that are crucial for preventing virus entry, replication, and systemic spread within the plant. Based on functional annotation and differential gene expression analysis, we identified the regulatory genes involved in triggering immune responses, modulating signal transduction, and specific host factors during CMV infection. To validate the RNA-seq findings, we selected four genes involved in resistance, virus multiplication, and virus spread and analyzed them using real-time quantitative reverse transcription PCR (qRT-PCR) with specific primers. The qRT-PCR results aligned closely with those from RNA-seq, showing consistent fold-change responses for the genes that were differentially expressed, indicating that the RNA-seq results were reliable. These results deepen our understanding of the complex genetics behind plant-virus interactions while also providing information for breeding programs that aim to develop CMV-resistant lily cultivars.

The swallowing reflex is modulated by multiple sensory inputs, such as bolus volume, viscosity, and taste. The interactions among different types of sensory information have been extensively studied. However, the influence of oral temperature on bolus volume perception has not been investigated. The aim of this study was to assess the effect of temperature on volume perception sensitivity in healthy individuals. Five volumes (5, 10, 15, 20, and 25 mL) of distilled water were estimated at three different temperatures, 4℃ (cold), 21℃ (room temperature), and 45℃ (warm), using a visual analogue scale. There were no significant differences in the sensitivity of oral volume perception across temperatures. These findings suggest that the ability to perceive bolus volume remains stable under temperature variation.

Chronic enteropathy (CE) in dogs presents with persistent symptoms such as vomiting, diarrhea, weight loss, and changes in appetite. Traditional diagnostic methods, including blood tests, ultrasound, and endoscopy, often fail to assess the entire small intestine. Capsule endoscopy offers a non-invasive approach, enabling comprehensive visualization of the gastrointestinal tract and enhancing diagnostic accuracy. In case 1, a 10-year-old Maltese with chronic diarrhea and significant weight loss underwent capsule endoscopy, revealing severe lacteal dilation and moderate gastric erythema, leading to a diagnosis of severe intestinal lymphangiectasia and moderate enteritis. Despite initial corticosteroid therapy and dietary changes, clinical improvement was limited. In case 2, an 11-year-old mixed-breed dog with chronic vomiting, anorexia, and weight loss was assessed. Capsule endoscopy detected moderate gastric erythema, severe small intestinal irregularities, and jejunal bleeding, diagnosing mild esophagitis, moderate gastritis, and severe enteritis with hemorrhage. Treatment with a hypoallergenic diet, corticosteroids, and acid suppressants resulted in gradual symptom relief. This report demonstrates that capsule endoscopy can be utilized as a screening tool for evaluating the mucosal status in patients with CE.

We previously reported that pyridoxine and its derivatives exert antidiabetic effects by alleviating postprandial hyperglycemia via inhibition of carbohydrate-hydrolyzing enzymes in normal sprague–dawley (SD) rats. In this study, we aimed to further evaluate whether long-term pyridoxal supplementation decreases the blood glucose levels using SD rats. SD rats were randomly assigned to groups fed a high-carbohydrate diet (66.1% cornstarch) with or without pyridoxal (4%) for 36 days. Changes in body weight, blood glucose levels, and food intake were measured daily for 36 days. Dietary supplementation with pyridoxal significantly decreased the blood glucose levels (P<0.001) and body weight (P<0.001) in mice. Glycated hemoglobin (HbA1c) levels, which are good indicators of plasma glucose concentrations over prolonged periods, were also significantly decreased over five weeks (P<0.001). Similarly, dietary treatment with Acarbose ® (0.04%), a positive control, also significantly decreased the blood glucose and HbA1c levels and body weight. Overall, our findings suggest that pyridoxal inhibits weight gain and alleviates postprandial hyperglycemia by decreasing glucose absorption and HbA1c levels.

Mesenchymal stem cells (MSCs) have emerged as a promising therapeutic resource for the peripheral nervous system (PNS) and central nervous system (CNS) that is attributable to their capacity for neuronal differentiation. Human dental pulp stem cells (hDPSCs), which exhibit MSC-like traits, can differentiate into neuron-like cells and secrete critical neurotrophic factors; however, their therapeutic potential in peripheral nerve injury remains unexplored. This study investigated the regenerative effects of hDPSC transplantation following sciatic nerve injury (SNI) in rats. Transplantation of hDPSCs, STRO-1+ hDPSCs, or CD146+ hDPSCs after sciatic nerve transection in rats upregulated the levels of β3 tubulin, a marker of immature newborn neurons. Furthermore, the levels of glial cellderived neurotrophic factor, insulin-like growth factor 2, and the neuroregenerative factor NeuroD1 were upregulated. Motor dysfunction in rats with SNI was restored, as demonstrated by significantly higher sciatic functional index scores compared with the sciatic nerve transection group without transplantation. Transplantation of hDPSCs into injured peripheral nerves results in the upregulation of neurotrophic factors, differentiation into immature neurons, and promotion of motor function recovery. This approach holds promise as a valuable therapeutic strategy for repairing injured peripheral sciatic nerves, potentially providing a solution for nerve damage in both the PNS and CNS.
