The emergence and rapid spread of the potentially fatal coronavirus disease 2019, caused due to infection by severe acute respiratory syndrome coronavirus-2, has led to worldwide interest in developing functional bioactive ingredients that act as immunomodulatory agents. In this study, we aimed to characterize Carica papaya extract and explore its potential as an immunomodulator by performing in vitro cell screening. Papaya leaf water extract (PLW) was found to significantly increase the levels of nitric oxide (NO) and prostaglandin E₂ (PGE₂) by upregulating inducible nitric oxide synthase and cyclo-oxygenase-2 activity, respectively. Additionally, PLW increased the production of tumor necrosis factor-α and interleukin 1β in RAW 264.7 cells. Furthermore, PLW activated the expression of c-Jun N-terminal kinase (JNK) and extracellular signal-regulated kinase (ERK) but not that of p38 mitogen-activated protein kinase. These results indicate that PLW increased the production of NO, PGE₂, and pro-inflammatory cytokines by activating the JNK and ERK pathways in macrophages, thus demonstrating immunomodulatory properties. Finally, high-performance liquid chromatography fingerprint analysis indicated the presence of rutin, narirutin, and ρ-coumaric acid in PLW (6.30, 119.76, and 47.25 ppm, respectively). Treating cells with these compounds at non-toxic concentrations had no effect on NO production. Taken together, these results suggest that PLW may have potential as an immunity-enhancing supplement.

Hyun-Su Lim,Su Bin Choi,Hanjung Kwon,Jae-Won Lim,Chul Jong Han,Jung-Min Oh,Jong-Woong Kim 대한금속·재료학회 2021 ELECTRONIC MATERIALS LETTERS Vol.17 No.6

To fabricate electrodes for use in fl exible electronic devices with improved resistance to the mechanical stresses induced byrepeated bending, we developed a highly fl exible and conductive composite comprised of Ti 3 C 2 -based MXene nanosheetsand Ag nanoparticles. Specifi cally, we synthesized Ti 3 C 2 -based MXene nanosheets and added them as a second fi ller to anAg dispersion to fabricate Ag–MXene composite paste. Although the synthesized MXene nanosheets are somewhat lesselectrically conductive than pure Ag nanoparticles, the conductivity of the pattern formed by printing this composite pastewas comparable to that of pure Ag nanoparticle-based electrode. Moreover, resistance in the resulting electrode remainedfairly constant despite repeated bending employing a curvature radius of 2 mm. We attribute this to the presence of theMXene nanosheets, whose homogeneously distributed hydroxyl or oxygen terminate surface functional groups preventedor delayed the propagation of cracks inside the printed pattern despite repeated bending.

Su-bin Kim,Chunghwi Yi,Seo-hyun Kim,Gyu-hyun Han,One-bin Lim 한국전문물리치료학회 2023 한국전문물리치료학회지 Vol.30 No.3

Background: In modern society, the use of computers accounts for a large proportion of our daily lives. Although substantial research is being actively conducted on musculoskeletal diseases resulting from computer use, there has been a recent surge in interest in improving the working environment for prevention. Objects: This study aimed to examine the effects of posture correction feedback (PCF) on changes in neck posture and muscle activation during computer typing. Methods: The participants performed a computer typing task in two sessions, each lasting 16 minutes. The participant’s dominant side was photographed and analyzed using ImageJ software to verify neck posture. Surface electromyography (EMG) was used to confirm the par-ticipant’s cervical erector spinae (CES) and upper trapezius muscle activities. The EMG signal was analyzed using the percentage of reference voluntary contraction and amplitude prob-ability distribution function (APDF). In the second session, visual and auditory feedback for posture correction was provided if the neck was flexed by more than 15° in the initial position during computer typing. A 20-minute rest period was provided between the two sessions. Results: The neck angle (p = 0.014), CES muscle activity (p = 0.008), and APDF (p = 0.015) showed significant differences depending on the presence of the PCF. Furthermore, signifi-cant differences were observed regarding the CES muscle activity (p = 0.001) and APDF (p = 0.002) over time. Conclusion: Our study showed that the feedback system can correct poor posture and re-duces unnecessary muscle activation during computer work. The improved neck posture and reduced CES muscle activity observed in this study suggest that neck pain can be prevented. Based on these results, we suggest that the PCF system can be used to prevent neck pain.

현수빈(Su Bin Hyun),현창구(Chang-Gu Hyun) 한국생물공학회 2020 KSBB Journal Vol.35 No.3

This study analyzed the antioxidant activity and skin primary irritation test by using hot-water extracts of Acca sellowiana leaves (WAL) and branches (WAB). Due to the recently warmed climate, Jeju Island produces subtropical plants, and the efficacy of one of them, A. sellowiana, has been confirmed. DPPH · ABTS · DMPD radical scavenging activity, ferrous-ion chelating activity, cupric reducing antioxidant capacity (CUPRAC), reducing power assay, ferric-reducing antioxidant power (FRAP) were teseted, and total phenol and phenol contents were analyzed. In addition, through skin primary irritation test, it was investigated whether it can be used as a cosmetic ingredient. As a result, in all antioxidant activity experiments, the activity of WAL and WAB increased in a concentration-dependent manner. In addition, the content of flavonoids was contained in the WAL more than WAB, and accordingly, the antioxidant activity of the WAL was better. In addition, WAL is hypoallergenic and WAB is a non-irritating ingredient, suggesting that it is possible as a natural material that can be used in cosmetics in the future.

Test–retest Reliability and Concurrent Validity of a Headphone and Necklace Posture Correction System Developed for Office Workers

Gyu-hyun Han,Chung-hwi Yi,Seo-hyun Kim,Su-bin Kim,One-bin Lim 한국전문물리치료학회 2023 한국전문물리치료학회지 Vol.30 No.3

Background: Office workers experience neck or back pain due to poor posture, such as flexed head and forward head posture, during long-term sedentary work. Posture correction is used to reduce pain caused by poor posture and ensures proper alignment of the body. Sev-eral assistive devices have been developed to assist in maintaining an ideal posture; however, there are limitations in practical use due to vast size, unproven long-term effects or inconsis-tency of maintaining posture alignment. We developed a headphone and necklace posture correction system (HANPCS) for posture correction using an inertial measurement unit (IMU) sensor that provides visual or auditory feedback. Objects: To demonstrate the test-retest reliability and concurrent validity of neck and upper trunk flexion measurements using a HANPCS, compared with a three-dimensional motion analysis system (3DMAS). Methods: Twenty-nine participants were included in this study. The HANPCS was applied to each participant. The angle for each action was measured simultaneously using the HANPCS and 3DMAS. The data were analyzed using the intraclass correlation coefficient (ICC) = [3,3] with 95% confidence intervals (CIs). Results: The angular measurements of the HANPCS for neck and upper trunk flexions showed high intra- (ICC = 0.954–0.971) and inter-day (ICC = 0.865–0.937) values, standard error of measurement (SEM) values (1.05°–2.04°), and minimal detectable change (MDC) values (2.92°–5.65°). Also, the angular measurements between the HANPCS and 3DMAS had excel-lent ICC values (> 0.90) for all sessions, which indicates high concurrent validity. Conclusion: Our study demonstrates that the HANPCS is as accurate in measuring angle as the gold standard, 3DMAS. Therefore, the HANPCS is reliable and valid because of its angular measurement reliability and validity.
