Woochan Chun,Hee-su Kim,Sieun Park,Jihea Park,Seunghee Shim,Sookyoung Park 한국전문물리치료학회 2021 한국전문물리치료학회지 Vol.28 No.3

Background: The foot is a complex body structure that plays an important role in static and dynamic situations. Previous studies have reported that altered foot posture might affect knee joint strength and postural stability, however their relationship still remains unclear. Objects: The purpose of this study was to identify whether pronated foot posture has an influence on knee isokinetic strength and static and dynamic postural stability. Methods: Forty healthy young males aged 18 to 26 years were included. Foot posture was evaluated using the Foot Posture Index-6 (FPI-6), and the subjects were divided into two groups according to their FPI-6 scores: a neutral foot group (n = 20, FPI-6 score 0 to +5) and a pronated foot group (n = 20, FPI-6 score +6 or more). Biodex Systems 3 isokinetic dyna-mometer was used to evaluate knee isokinetic strength and hamstring to quadriceps ratio at three angular velocities: 60°/sec, 90°/sec, and 180°/sec. The static and dynamic postural stabil-ity in a single-leg stance under the eyes-open and eyes-closed conditions were measured with a Biodex Balance System. Results: There were no significant differences between the groups in knee isokinetic strength and static postural stability (p > 0.05), but there was a significant difference in the medial–lateral stability index (MLSI) for dynamic postural stability under the eyes-closed condition (p = 0.022). The FPI-6 scores correlated significantly only with the dynamic overall stability index (OSI) and the MLSI (OSI: R = 0.344, p = 0.030; MLSI: R = 0.409, p = 0.009) under the eyes-closed condition. Conclusion: Participants with pronated foot had poorer medial–lateral dynamic stability un-der an eyes-closed condition than those without, and FPI-6 scores were moderately positively correlated with dynamic OSI and dynamic MLSI under the eyes-closed condition. These results suggest that pronated foot posture could induce a change in postural stability, but not in knee isokinetic strength.

Choi, Jihea,Park, Yon Chul,Choi, Sarah Korean Academy of Child Health Nursing 2021 Child Health Nursing Research Vol.27 No.1

Purpose: This study aimed to develop a mobile-based self-management health alarm (MSHA) program for modifying obese children's lifestyle based on the information-motivation-behavioral skills (IMB) model and to test its feasibility. Methods: A methodological study for the development of the MSHA program and pilot study with a one-group pretest-posttest design for feasibility testing was conducted. The MSHA program was designed to provide obesity-related information (I), monitor daily diet and exercise, provide motivational text messages (M), and enhance healthy diet and exercise skills (B) via a mobile-based web platform. In the feasibility test, six obese children participated in the 4-week program, and the number of days per week that they achieved their goals and differences in metabolic components were assessed. Data were analyzed using descriptive statistics and the Wilcoxon signed-rank test. Results: Participants successfully achieved their diet and exercise goals≥5 days per week. Body mass index (z=-1.99, p=.046), waist circumference (z=-2.20, p=.028), and triglyceride levels (z=-2.21, p=.027) significantly decreased. Conclusion: The MSHA program showed positive effects on health behaviors and metabolic syndrome risk. The program may be effective in improving metabolic syndrome in obese children by promoting self-health management behaviors.

Purpose: Interpersonal competence, a key competence for patient-centered care by nurses, should be understood. Therefore, factors influencing the interpersonal competence of nursing students should be identified to explore and enhance their interpersonal relationships during the undergraduate educational curriculum for nursing educators. In this study factors influencing interpersonal competence, especially on self-assertiveness and empathy in nursing students were identified and analysed. Methods: A cross-sectional study design was used for the study in two Korean nursing colleges with similar baccalaureate nursing curricula. A total of 251 nursing students from freshman to senior year completed a questionnaire to measure related factors that were assumed to influence nursing students’ interpersonal competence. Data were collected from October 11~31, 2016. Study variables included self-assertiveness, empathy, interpersonal competence, and socio-demographic status. Multiple regression analysis was used for data analysis. Results: Nursing students’ interpersonal competence was explained by personality (β=.22), self-assertiveness (β=.16) and empathy (β=.38). The explanatory power of these predictors was 26.8% (p<.001). Conclusions: Nursing students’ interpersonal competence during the undergraduate nursing years can be enhanced by educational strategies that improve their interpersonal relationship as patient-centered care providers. Simultaneously, the attitude of the nurse educator is also important for nursing students who are to be treated as valuable learners and to improve students" empathy and self-assertiveness ability.

CXCR2 Inhibition in Human Pluripotent Stem Cells Induces Predominant Differentiation to Mesoderm and Endoderm Through Repression of mTOR, β-Catenin, and hTERT Activities

Jung, Ji-Hye,Kang, Ka-Won,Kim, Jihea,Hong, Soon-Chul,Park, Yong,Kim, Byung Soo Mary Ann Liebert, Inc. 2016 STEM CELLS AND DEVELOPMENT Vol.25 No.13

<P>On the basis of our previous report verifying that chemokine (C-X-C motif) receptor 2 (CXCR2) ligands in human placenta-derived cell conditioned medium (hPCCM) support human pluripotent stem cell (hPSC) propagation without exogenous basic fibroblast growth factor (bFGF), this study was designed to identify the effect of CXCR2 manipulation on the fate of hPSCs and the underlying mechanism, which had not been previously determined. We observed that CXCR2 inhibition in hPSCs induces predominant differentiation to mesoderm and endoderm with concomitant loss of hPSC characteristics and accompanying decreased expression of mammalian target of rapamycin (mTOR), β-catenin, and human telomerase reverse transcriptase (hTERT). These phenomena are recapitulated in hPSCs propagated in conventional culture conditions, including bFGF as well as those in hPCCM without exogenous bFGF, suggesting that the action of CXCR2 on hPSCs might not be associated with a bFGF-related mechanism. In addition, the specific CXCR2 ligand growth-related oncogene α (GROα) markedly increased the expression of ectodermal markers in differentiation-committed embryoid bodies derived from hPSCs. This finding suggests that CXCR2 inhibition in hPSCs prohibits the propagation of hPSCs and leads to predominant differentiation to mesoderm and endoderm owing to the blockage of ectodermal differentiation. Taken together, our results indicate that CXCR2 preferentially supports the maintenance of hPSC characteristics as well as facilitates ectodermal differentiation after the commitment to differentiation, and the mechanism might be associated with mTOR, β-catenin, and hTERT activities.</P>

활성화된 단핵구의 동형성 세포 부착(동형성 응집)은 염증반응, 분화, 이동과 같은 생리학적, 병리학적 과정에서 중요한 역할을 한다. 매실 추출물은 항바이러스, 항균, 항암작용과 같은 효과를 보인다고 알려 져있다. 따라서, 매실 추출물은 단핵구의 동형성 응집 억제를 통해 염증반응을 조절할 가능성을 가진다. 본 연구에서는, 염증성 질환에서 매실 추출물의 치료효능을 뒷받침할 수 있는 분자적 기전을 조사하였다. 매실 추출물이 지질다당질(LPS)로 활성화된 단핵구의 동형성 응집을 억제함을 확인하였다. 이러한 효과는 LPS로 활성화된 THP-1 세포의 iNOS 단백질 발현 억제를 통해, 산화질소(NO) 생산의 감소로 조절되는 것을 발견하였다. 또한 NO 생성물질인 SNAP 처리 실험을 통해 단핵구 동형성 응집을 억제하는데 매실에 의한 NO 억제가 필수적인 기작임을 확인하였다. 게다가, 매실 추출물은 LPS로 유도된 IκB-α 의 인산화와 NF-κB의 핵내로의 이동을 현저하게 감소시키는 것을 확인하였다. 매실 추출물은 NO생성과 NF-κB 활성 억제를 통해 LPS로 활성화된 단핵구의 동형성 응집을 저해하고 이를 통해 항염증 효과를 유도할 수 있다는 결론으로부터 만성 염증성 질환의 치료와 예방에 매실 추출물의 효능을 제시하고자 한다. Homotypic cell adhesion (homotypic aggregation) in activated monocytes plays a central role in physiological and pathological processes including inflammatory responses, differentiation and migration. The extract of the Prunus mume Sieb. et Zucc. fruit (Maesil) has potential benefits to human health; such as anti-viral, anti-microbial, and anti-cancer activities. Indeed, Maesil extract may modulate inflammatory responses via interference with homotypic aggregation in monocytes. In the present study, the molecular mechanisms underpinning the therapeutic efficacy of Maesil extract in inflammatory diseases were investigated. It was found that Maesil extract inhibited homotypic aggregation in lipopolysaccharide (LPS)-activated monocytes. This was mediated by reduction of nitric oxide (NO) production, partly via inhibition of inducible nitric oxide synthase (iNOS) expression in LPS-activated THP-1 cells. It was confirmed that NO inhibition is a key mechanism in Maesil induced blockade of monocyte aggregation through identification of reversal of this inhibitory effect by the NO-producing agent S-nitroso-N-acetyl penicillamine (SNAP). In addition, Maesil extract significantly attenuated LPS-induced IκB-α phosphorylation and NF-κB translocation into the nucleus. In conclusion, Maesil extract exerts anti-inflammatory effects via inhibition of homotypic aggregation of LPS-activated monocytes through mechanisms involving the suppression of NO production and NF-κB activity, suggesting Maesil extract as a potential therapeutic candidate for the prevention and treatment of chronic inflammatory diseases.
