Purpose: Persimmon (Diospyros kaki Thunb.) is rich in phytochemicals (e.g., tannin and beta-carotene.), vitamins (e.g., vitamins A and C), minerals (e.g., calcium and potassium), and dietary fiber. Persimmon exhibits efficacy against diseases such as cancer, hypertension, and heart disease. This study examined the antioxidant and immune-enhancing activities of Fuyu (a sweet persimmon) and Hachiya (an astringent persimmon) and evaluated their potential as functional food ingredients. Methods: The antioxidant and immune-enhancing activities of Fuyu and Hachiya persimmons were evaluated by extracting them with hot water and ethanol (100%). The antioxidant activity was assessed by measuring the total phenolic content (TPC), total flavonoid content (TFC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (RSA), and oxygen radical absorbance capacity (ORAC). Six-year domestic red ginseng was used as a reference for assessing the immune-enhancing activity. Nitric oxide (NO) production, phagocytosis, cytokine levels interleukin [IL]-2, IL-4, IL-10, and interferon-γ), and inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) gene expression were analyzed. Results: The hot water extracts of Fuyu and Hachiya persimmon exhibited significantly higher TPC, TFC, DPPH RSA, and ORAC levels than the ethanol extract. The Hachiya persimmon extract generally showed comparable or higher immune-enhancing activity than the Fuyu persimmon extract in NO production, cytokine activity, phagocytosis, and expression of iNOS and COX-2 genes. Conclusion Hachiya persimmon possesses superior antioxidant properties to Fuyu persimmon while exhibiting comparable immune-enhancing activity. These characteristics highlight its potential for beneficial applications. Nevertheless, further research is required to elucidate these effects and optimize their use in health-promoting interventions.

Background: Renal replacement therapy (RRT) is an important treatment option for sepsisassociated acute kidney injury (AKI); however, the optimal timing for its initiation remains controversial. Herein, we investigated the clinical outcomes of early continuous kidney replacement therapy (CKRT), defined as CKRT initiation within 6 hours of sepsis-associated AKI onset, which was earlier than the initiation time defined in previous studies. Methods: We used clinical data sourced from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. This study included patients aged ≥ 18 years who met the sepsis diagnostic criteria and received CKRT because of stage 2 or 3 AKI. Early and late CKRTs were defined as CKRT initiation within 6 hours and after 6 hours of the development of sepsisassociated AKI, respectively. Results: Of the 33,236 patients diagnosed with sepsis, 553 underwent CKRT for sepsisassociated AKI. After excluding cases of early mortality and patients with a dialysis history, 45 and 334 patients were included in the early and late CKRT groups, respectively. After propensity score matching, the 28-day mortality rate was significantly lower in the early CKRT group than in the late CKRT group (26.7% vs. 43.9%, P = 0.035). The early CKRT group also had a significantly greater number of days free of mechanical ventilation (median, 19; interquartile range [IQR], 3–25) and vasopressor administration (median, 21; IQR, 5–26) than the late CKRT group did (median, 10.5; IQR, 0–23; P = 0.037 and median, 13.5;IQR, 0–25; P = 0.028, respectively). The Kaplan–Meier curve also showed that early CKRT initiation was associated with an improved 28-day mortality rate (log-rank test, P = 0.040).In contrast, there was no significant difference in the 28-day mortality between patients who started CKRT within 12 hours and those who did not (log-rank test, P = 0.237). Conclusion Early CKRT initiation improved the survival of patients with sepsis-associated AKI. Initiation of CKRT should be considered as early as possible after sepsis-associated AKI onset, preferably within 6 hours.

A wave of new technologies has created opportunities for the cost-effective generation of high-throughput profiles of biological systems, foreshadowing a "data-driven science" era. The large variety of data available from biological research is also a rich resource that can be used for innovative endeavors. However, we are facing considerable challenges in big data deposition, integration, and translation due to the complexity of biological data and its production at unprecedented exponential rates. To address these problems, in 2020, the Korean government officially announced a national strategy to collect and manage the biological data produced through national R&D fund allocations and provide the collected data to researchers. To this end, the Korea Bioinformation Center (KOBIC) developed a new biological data repository, the Korea BioData Station (K-BDS), for sharing data from individual researchers and research programs to create a data-driven biological study environment. The K-BDS is dedicated to providing free open access to a suite of featured data resources in support of worldwide activities in both academia and industry.

Pyoderma gangrenosum (PG) is a rare, non-infectious, neutrophilic dermatosis characterized by painful ulcers with indistinct borders and peripheral erythema. The diagnosis of PG requires the exclusion of other causes of similar appearing skin manifestations, including vasculitis and infections. The pathogenesis of PG is not clear; however, dysregulation of the immune system has been suggested in previous studies. More than half of the PG patients have underlying diseases; the most common being inflammatory bowel disease (IBD). The progression of PG in IBD patients is seen after the onset of IBD, usually during its exacerbation. On the other hand, PG may follow a course independent of the intestinal disease. We present a case of an 18-year-old young male with PG that presented before being diagnosed with ulcerative colitis as an associated condition. He had a painful ulcerative lesion on his right shin with no previous gastrointestinal symptoms. This case suggests that investigating for underlying disorders is essential in PG patients despite the lack of symptoms other than the skin lesions.

Life cycle stages, including daughter sporocysts, cercariae, and metacercariae, of Parvatrema duboisi (Dollfus, 1923) Bartoli, 1974 (Digenea: Gymnophallidae) have been found in the Manila clam Ruditapes philippinarum from Aphaedo (Island), Shinan-gun, Jeollanam-do, Korea. The daughter sporocysts were elongated sac-like and 307-570 (av. 395) μm long and 101-213 (av. 157) μm wide. Most of the daughter sporocysts contained 15-20 furcocercous cercariae each. The cercariae measured 112-146 (av. 134) μm in total length and 35-46 (av. 40) μm in width, with 69-92 (av. 85) μm long body and 39-54 (av. 49) μm long tail. The metacercariae were 210-250 (av. 231) μm in length and 170-195 (av. 185) μm in width, and characterized by having a large oral sucker, genital pore some distance anterior to the ventral sucker, no ventral pit, and 1 compact or slightly lobed vitellarium, strongly suggesting P. duboisi. The metacercariae were experimentally infected to ICR mice, and adults were recovered at day 7 post-infection. The adult flukes were morphologically similar to the metacercariae except in the presence of up to 20 eggs in the uterus. The daughter sporocysts and metacercariae were molecularly (ITS1-5.8S rDNA-ITS2) analyzed to confirm the species, and the results showed 99.8-99.9% identity with P. duboisi reported from Kyushu, Japan and Gochang, Korea. These results confirmed the presence of various life cycle stages of P. duboisi in the Manila clam, R. philippinarum, playing the role of the first as well as the second intermediate host, on Aphae-do (Island), Shinan-gun, Korea.
