Purpose: This study was done to better understand how sick children and their families define chronic illness; what behaviors they used for managing chronic illness; and how they perceived the socio-cultural context of Korea. Methods: This study was a secondary analysis of qualitative studies. Articles on children with a chronic illness and their families located in electronic databases were selected for review. Twenty one qualitative studies were reviewed. Qualitative studies that had used an analysis tool, the Family Management Style Framework were reviewed. Results: Children with chronic illness and their families tended to accept illness as a negative outcome and thought that they were deprived of the context of normality. In the traditional Korean family style, parents-in-law demand absolute obedience from their daughter-in-law, leading to a conflict between the two parties, which, in turn, may have negatively affected their perceptions of chronic illness. Western and oriental medical treatments were used, and participants sought an array of folk remedies. Conclusion: Culturally specific findings can help to better understand the difficulties faced by children with a chronic illness and their families and can provide invaluable input into the development of culturally appropriate and sensitive nursing interventions.
Cytosine arabinoside(AraC) inhibits DNA synthesis and ${\beta}$-DNA polymerase, an enzyme involved in DNA repair. This, a potent antimitotic agent, is clinically used as an anticancer drug with side effect of severe neurotoxicity. Earlier reports suggested that inhibition of neuronal survival by AraC in sympathetic neuron may be due to the inhibition of a 2'-deoxycytidine-dependent process that is independent of DNA synthesis or repair and AraC induced a signal that is triggers a cascade of new mRNA and protein synthesis, leading to apoptotic cell death in cultured cerebellar granule cells. The present study would suggest whether caspase family(ICE/CED-3-like protease) involved in AraC-induced apoptosis pathway of PC12 cells. It was observed that treatment of PC12 cells with AraC led to decrease of viability by MTT assay and morphology changes, which did not suggest that AraC induced apoptosis in PC12 cells. The mRNA of caspase-1/caspase-3 were expressed in PC12 cells constitutively, and AraC did not activate caspase family. These results suggest that caspase-1/caspase-3 may not be required for AraC-induced cell death pathway in PC12 cells.
Although sanguinarine, a benzophenanthridine alkaloid, possesses anti-cancer properties against several cancer cell lines, the molecular mechanisms by which it inhibits cell growth and induces apoptosis have not been clearly understood. In order to further explore the critical events leading to apoptosis in sanguinarine-treated MCF-7 human breast carcinoma cells, the following effects of sanguinarine on components of the mitochondrial apoptotic pathway were examined: generation of reactive oxygen species (ROS), alteration of the mitochondrial membrane potential (MMP), and the expression changes of Bcl-2 family proteins. We show that sanguinarine-induced apoptosis is accompanied by the generation of intracellular ROS and disruption of MMP as well as an increase in pro-apoptotic Bax expression and a decrease of anti-apoptotic Bcl-2 and Bcl-xL expression. The quenching of ROS generation with N-acetyl-L-cysteine, the ROS scavenger, protected the sanguinarine-elicited ROS generation, mitochondrial dysfunction, modulation of Bcl-2 family proteins, and apoptosis. Based on these results, we propose that the cellular ROS generation plays a pivotal role in the initiation of sanguinarine-triggered apoptotic death.
Src-family kinases are critically involved in the control of cytoskeleton organization and in the generation of integrin-dependent signaling responses, inducing tyrosine phosphorylation of many signaling and cytoskeletal proteins. Activity of the Src family of tyrosine kinases is tightly controlled by inhibitory phosphorylation of a carboxy-terminal tyrosine residue, inducing an inactive conformation through binding with its SH2 domain. Dephosphorylation of C-ter tyrosine, as well as its deletion of substitution with phenylalanine in oncogenic Src kinases, leads to autophosphorylation at a tyrosine in the activation loop, thereby leading to enhanced Src activity. Beside this phophorylation/dephosphorylation circuitry, cysteine oxidation has been recently reported as a further mechanism of enzyme activation. Mounting evidence describes Src activation via its redox regulation as a key outcome in several circumstances, including growth factor and cytokines signaling, integrin-mediated cell adhesion and motility, membrane receptor cross-talk as well in cell transformation and tumor progression. Among the plethora of data involving Src kinase in physiological and pathophysiological processes, this review will give emphasis to the redox component of the regulation of this master kinase.
This study examined the effects of perceived discrimination on multicultural adolescents regarding feelings of This study examined the direct effect of socially prescribed perfectionism on interpersonal anxiety in upper elementary school students and the sequential mediating effect of dichotomous thinking and rejection sensitivity on this relationship. The sample comprised 306 upper elementary school students (grades 4 to 6; 149 boys, 48.7%) in Seoul, Incheon, and Busan. The Data were collected through an online self-report questionnaire completed by the participants and analyzed using SPSS version 27.0 and MPlus version 8.7 software. The analyses revealed three key findings. First the direct effect of socially prescribed perfectionism on interpersonal anxiety was not statistically significant. Second dichotomous thinking mediated the relationship between socially prescribed perfectionism and interpersonal anxiety, whereas rejection sensitivity did not. Finally, socially prescribed perfectionism influenced interpersonal anxiety through the sequential mediation of dichotomous thinking and rejection sensitivity. In conclusion, although socially prescribed perfectionism does not directly influence interpersonal anxiety, children may experience interpersonal anxiety in situations involving dichotomous thinking due to socially prescribed perfectionism, leading to rejection sensitivity. These findings suggest that interventions for interpersonal anxiety in upper elementary school students should focus on psychological problems attributed to socially prescribed perfectionism.
About 0.8 million people die because of hepatitis B virus (HBV) infection each year. In around 5% of infected adults, the immune system is ineffective in countering HBV infection, leading to chronic hepatitis B (CHB). CHB is associated with hepatocellular carcinoma, which can lead to patient death. Unfortunately, although current treatments against CHB allow control of HBV infection, they are unable to achieve complete eradication of the virus. Cytokines of the IFN family represent part of the innate immune system and are key players in virus elimination. IFN secretion induces the expression of interferon stimulated genes, producing proteins that have antiviral properties and that are essential to cell-autonomous immunity. IFN-α is commonly used as a therapeutic approach for CHB. In addition, IFN-γ has been identified as the main IFN family member responsible for HBV eradication during acute infection. In this review, we summarize the key evidence gained from cellular or animal models of HBV replication or infection concerning the potential anti-HBV roles of IFN-γ with a particular focus on some IFN-γ-inducible genes.
Severe fever with thrombocytopenia syndrome virus (SFTSV) is a zoonotic, tick-borne RNA virus of the genus Bandavirus (Family Phenuiviridae), mainly reported in China, Japan, and the Republic of Korea (Korea). For the purpose of this study, a total of 3,898 adult and nymphal ticks of species Haemaphysalis longicornis (94.2%), Haemaphysalis flava (5.0%), Ixodes nipponensis (0.8%), and 1 specimen of Ixodes ovatus, were collected from the Deogyusan National Park, Korea, between April 2016 and June 2018. A single-step reverse transcriptase-nested PCR was performed, targeting the S segment of the SFTSV RNA. Total infection rate (IR) of SFTSV in individual ticks was found to be 6.0%. Based on developmental stages, IR was 5.3% in adults and 6.0% in nymphs. The S segment sequences obtained from PCR were divided into 17 haplotypes. All haplotypes were phylogenetically clustered into clades B-2 and B-3, with 92.7% sequences in B-2 and 7.3% in B-3. These observations indicate that the Korean SFTSV strains were closer to the Japanese than the Chinese strains. Further epidemiological studies are necessary to better understand the characteristics of the Korean SFTSV and its transmission cycle in the ecosystem.
This paper is searching the meaning of Gangseong(姜聖) which came from Gucheon Sangje(九天上帝, the Lord and Creator of the Great Origin of the Ninth Heaven) incarnated in the Gang(姜) family. To study the meaning of Gangseong(姜聖), this paper concentrate on Maitreya(彌勒尊佛) and the sentence about Wonsibanbon(原始返本) Sangje's incarnation in the Gang's family appeared on term Gangseong in the middle of divinity terms(九天應元雷聲普化天尊姜聖上帝). Furthermore, Sangje's surname Gangseong(姜姓) has relation with Maitreya and the sentence about Wonsibanbon. What Maitreya has relation with Gangseong(姜聖) is the legendary poem that Maitreya Statue became complete woman(六丈金佛 化爲全女) and what Wensibanbon has relation with Gangseong is the fact that family name Gang is primary surname all over the world's human beings. Wonsibanbon comprises correction of family lineage and theocracy(政敎一致) which came from tracing and reviving the beginning. As a primary family name, Sangje's incarnation family name Gang plays a leading edge role of religious activity of Sangje because primary family name Gang represents the one and only Truth(眞法) or the principle of Wensibanbon which means the union[unity] of religion and politics(政敎一致), and combining saintliness and heroism (聖雄兼備). According to the one and only Truth(眞法) like this, the first emergence and role of the completely "DoTongKunJa" (道通君子, the perfection of man with Dotong) who Sang-Je declared will build the union[unity] of religion and politics shows realization of advance-oriented salvation. Under the principle of Yangsan(兩山, twin mountain, 甑山, 鼎山, the three-story Maitreya Statue of Geumsan Temple) which implies emergence of the completely "DoTongKunJa"(道通君子) who will accomplish the union[unity] of religion and politics(政敎一致), combining saintliness and heroism(聖雄兼備) and advent of the one and only Truth(眞法出現). This could be possible by the almighty of Sangje who incarnated in Gang's family name according to the principle of Wensibanbon from the text Jeonkyung(典經) as shown. Adjusting family lineage (血統) means to straighten out the relation between ancestors and descendants, and which has close relation with the activity after Sangje's incarnation in Gang's family name according to the principle of Wensibanbon. As far as family lineage was concerned, there are three aspects of close relation between ancestors and descendants. First, general connection between ancestors and descendants, Second Dotong(道通)-related connection, Third after -death entrance(冥府)-related connection. Descendants should know a family history from moral laws of family relationships(天倫) by the Compatibility principle. As for second Dotong-related connection between ancestors and descendants, the fact descendants' Dotong can be accomplished by the act of ancestors' charity shows human beings world(人間界) where descendants live has close organic relation with divine world(神明界) where ancestors live. As for third after-death entrance-related connection between ancestors and descendants, after-death entrance are totally related with both Heavenly order(天道) of ancestors and Humane-order(人道) of descendants. At this point, we can see the relation between ancestors and descendants are very close and organic. As shown from the text Jeonkyung, Sangje as Gucheon Sangje(九天上帝, the Lord and Creator of the Great Origin of the Ninth Heaven) and Maitreya(彌勒尊佛) has descended to the earth adopting Gang's family name according to principle Wensibanbon. By Sangje's incarnation in Gang's family name, the legitimacy of the religion and the perfection of Do could be successed under the law of Yangsan(兩山). Furthermore, Sangje realize the one and only Truth by Adjusting family lineage and producing the completely "true man" through Cheonji Gongsa.

Purpose : We screened more than 350 compounds with an endoperoxide ring structure in search of an anti-leukemic drug and found that compound 127 (c-127) could induce significant cytotoxicity in HL-60 cells. In this study, we investigated the molecular mechanisms of compound 127-induced antitumor activity on HL-60 cells. Methods : HL-60 cells were cultured in Rosewell Park Memorial Institute 1640 and cell viability was measured by MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide], a tetrazole assay. Apoptosis was assessed by a DNA fragmentation test. Apoptotic machineries were determined by Western blot analysis. Results : C-127 could induce a cytotoxic effect at 24 h and apoptosis at 6 h, which was demonstrated with MTT assay and DNA fragmentation test, respectively. The apoptotic effect of this drug was caused by the activation of the intracellular caspase-8,3 activation, the cleavage of pro-apoptotic Bid, and the increase of c-Jun expression accompanied with JNK (Jun N-terminal kinases) phosphorylation. On the contrary, it increased the expression of anti-apoptotic Bcl-2 levels, leading to the induction of the induction of anti-apoptotic effect. Taken together, the present study demonstrated that c-127 was a potent inducer of cytotoxicity on HL-60 cells through apoptotic mechanisms, which included the activation of caspase family, the regulation of Bcl-2 family, and the activation of JNK signaling pathway. Conclusion : Our results suggest that c-127 has a strong antitumor activity through the regulation of various apoptotic machineries on HL-60 cells. The compound may be utilized as an effective and potentially therapeutic drug in leukemia.

Worldwide, tuberculosis remains one of the leading infectious diseases, accounting for nearly 3 million deaths and more than 8 million new cases annually. DNA typing of Mycobacterium tuberculosis is important for the control of tuberculosis, since it can be used to track transmission route of tuberculosis, source of internal laboratory contaminations, and to answer questions on the nature of tuberculosis infections such as reactivation or exogenous reinfection of disease. At present, IS6110-based RFLP is the choice of method for typing large numbers of clinical isolates of M. tuberculosis, since it has the highest resolution power. However, RFLP requires long time, high cost and qualified experts, so only reference level laboratories can use the RFLP technique. In order to have an optional molecular typing method suitable for the clinical settings, this study evaluated the use of one of PCR-based typing methods, IS6110-based outward PCR for typing clinical isolates of M. tuberculosis. In brief, the results from this study showed that IS6110-based RFLP is useful to discriminate diverse clinical isolates of M. tuberculosis as well as to identify clinical isolates that belong to the same family or cluster groups that have been previously classified by RFLP analysis. In addition, the banding profiles resulted from IS6110-based outward PCR seemed to represent genomic characteristics of M. tuberculosis, since strains belong to the K-family generated unique band that is not present in any other strains but present only in the genome of K-family strains. The IS6110-based outward PCR was also shown to be useful with DNAs isolated directly from liquid cultures indicating this method can be suitable for typing M. tuberculosis in clinical settings.
