PURPOSE: This study examined the relationships among menopausal symptom, self-efficacy, health promoting behaviors, and investigated factors affecting health promoting behaviors of teachers with middle-aged women experiencing menopause. METHODS: From September to October 2012, a convenience sample of 252 subjects aged 40 to 60 years was recruited from 8 elementary schools, 3 middle schools and 5 high schools. The data analysis was done by ANOVA and stepwise multiple regression. RESULTS: Menopausal symptom of subjects was slightly lower than general middle aged women and the average level of health promoting behaviors was similar to general middle aged women. Health promoting behaviors were differentiated by severity of menopausal symptom, not by menstruation state. Menopausal symptom was negatively related to health promoting behaviors. The most significant factor affecting health promoting behaviors was self efficacy (14.3%). The combination of self efficacy, menopausal symptom, and elementary school teachers accounted for 20.1% of health promoting behavior. CONCLUSION: When developing health promotion program for teachers with middle-aged women, such program should consider self-efficacy, menopausal symptom, and school type.

This study was performed to observe the therapeutic effects of interferon-gamma(IFN-gamma) and gamma-globulin(gamma-globulin) in experimental Pneumocystis carinii pneumonia of immune suppressed mice. After 9 weeks, trimethoprim-sulfamethoxazole(TMP-SMZ; 10-50 mg/mouse/day), mouse IFN-gamma(5 x 10(4) units/mouse/day) and mouse gamma-globulin(20 mg/mouse/day) were administered to the mice for 3 weeks by the experimental group. The therapeutic efficacy was evaluated by body weights, histopathologic and electron microscopic findings of the lungs, and number of P. carinii cysts by Gomori's methenamine silver stain. Body weights of the mice were significantly increased in the group of combination therapy of TMP-SMZ with IFN-gamma or gamma-globulin, and in the group of TMP-SMZ treatment (p < 0.05), however, little effect was found in the group of gamma-globulin alone. Histopathologic findings of P. carinii pneumonia were much improved in the group of combination therapy of TMP-SMZ with IFN-gamma. Treatment with either TMP-SMZ or IFN-gamma significantly reduced the number of cysts in the P. carinii pneumonia, but gamma-globulin alone was ineffective. In electron microscopic findings of P. carinii pneumonia, the number of trophozoites and cysts were reduced by treatment with either TMP-SMZ or IFN-gamma, and most of the cysts were empty or containing one or two intracystic bodies. The present results suggested, that combination therapy of TMP-SMZ with IFN-gamma had synergistic effects in treatment of P. carinii pneumonia in experimental mice.

Triple-negative breast cancer (TNBC) is an aggressive cancer subtype lacking targeted therapies and is characterized by highrecurrence rates and poor prognosis. Recent advances in targeting DNA damage response (DDR) pathways using poly (ADP‒ri-bose) polymerase (PARP) inhibitors offer promising therapeutic strategies, especially for TNBC patients with BRCA1/2 mutations.This study reports the development and characterization of ART-446, a novel and selective CHK2 inhibitor. ART-446 showed potent activity against TNBC, regardless of BRCA deficiency, and it also reversed PARP inhibitor resistance. ART-446 potentlyinhibited CHK2 (IC50 : 9.06 nM) with high selectivity over other kinases; it synergized with the PARP inhibitor olaparib, enhancingDNA damage, inducing G2/M cell cycle arrest, and promoting apoptosis in both BRCA-mutant and wild-type TNBC cells. Mechanistic analyses revealed that ART-446 sensitized BRCA mutant and WT cells to PARP inhibitors by impairing DNA repair and increasing the accumulation of DNA damage. Importantly, ART-446 disrupted both homologous recombination and nonhomologous end-joining repair pathways, addressing a key limitation of PARP inhibitor monotherapy—resistance in BRCA-proficient cancers.In vivo, the combination of ART-446 and olaparib significantly reduced tumor growth in TNBC xenograft models without noticeable toxicity. The combined treatment increased DNA damage signaling, as evidenced by elevated γH2AX levels, and enhanced the sensitivity of BRCA2-deficient cells to ART-446. These findings underscore the potential of ART-446 to exploit DNA repair deficiencies and overcome resistance mechanisms associated with PARP inhibitors. By addressing the limitations of current treatments and expanding the utility of PARP inhibitors, ART-446 represents a promising candidate for DDR-targeted therapies, offering a novel approach to improve the outcomes of patients with TNBC.

PURPOSE: The purpose of this study was to explore and understand customized home visiting nurses' experiences in telephone visiting. METHODS: Qualitative data were collected from several discussions of 4 focus groups consisting of 20 customized home visiting nurses. All interviews were recorded and transcribed according to thematic content analysis processes. RESULTS: The five main themes on customized home visiting nurses' experiences of telephone visiting were 'greeting', 'counseling', 'using strategies', 'maintaining attitude for enhancing relations' and 'enduring difficulties'. The category of 'counseling' was composed of confirming, educating, supporting, adjusting, and indicating. And, the category of 'using strategies' included complimenting, scolding, persuading, compensating, and ignoring. CONCLUSION: Developing a standardized manual on telephone visiting is needed to guide an effective counseling. In order for a customized home visiting nurse to be a good telephone counselor, training of motivational interviewing is recommended.

A xanthoma is a localized collection of tissue histiocytes containing lipid and is usually associated with hyperlipidemia. Tendinous and tuberous xanthomatosis have been found in association with familial hypercholesterolemia, Type III hyperlipidemia, beta-sitosterolemia and cerebrotendinous xanthomatosis. Tendinous and tuberous xanthomatosis without hyperlipidemia have been reported very rarely. Especially tendinous xanthomatosis without hyperlipidemia have not been reported at all in korea. We are reporting a patient with tendinous and tuberous xanthomatosis accompanied by normal plasma lipids
