  • This study was performed to investigate the physiological functionality of jerusalem artichokes and to define its antioxidant potential. The study also evaluated mook prepared with jerusalem artichokes powder as a new functional food for ameliorating Diabetes Mellitus. Regarding the chromaticity of mook prepared with jerusalem artichoke, lightness decreased as the amount of jerusalem artichoke increased (p < 0.05), while the redness and yellowness values increased significantly (p < 0.05). Regarding the mechanical properties, hardness, springiness, chewiness, gumminess, and cohesiveness decreased significantly as the amount of jerusalem artichoke increased (p < 0.05). The total polyphenol and flavonoid contents of JA30 were 7.36 mg TAE/g and 2.15 mg RE/g, respectively, which were higher than those of the control group(3.50 mg TAE/g and 0.76 mg RE/g, respectively). The DPPH and ABTS scavenging abilities ($IC_{50}$) for JA30 were 4.40 and 5.70 mg/mL, respectively, indicating a higher radical scavenging ability than the control group (7.59 and 7.24 mg/mL, respectively). The ${\alpha}-glucosidase$ inhibitory effect ($IC_{50}$) of JA30 and the control group was 18.91 and 24.01 mg/mL, respectively. Based on the above-described results, mook containing jerusalem artichoke powder is expected to ameliorate diabetes with antioxidant activity, ${\alpha}-glucosidase$ inhibitory effect, and sensory factor. Also, it is believed that this functional material has the potential to improve health.

  • This study was conducted to investigate changes in composition of ginsenosides and color of processed ginsengs prepared by different steaming-drying times. Processed ginsengs were prepared from white ginseng with skin by 9-time repeated steaming at $96^{\circ}C$ for 3 hours and followed by hot air-drying at $50^{\circ}C$ for 24 hours. As the times of steaming processes increased, lightness (L value) decreased and redness (a value) increased in color of ginseng powders. Crude saponin contents and ginsenosides compositions in processed ginsengs prepared by different steaming-drying times were investigated using the HPLC method, respecively. Crude saponin contents according to increasing steaming-drying times decreased in some degree. In the case of major ginsenosides, the contents of $Rb_1$, $Rb_2$, Rc, Rd, Rf, Re, $RG_1$, Re were decreased with increase in steamimg times, but those of $Rh_1$, $Rg_3$, $Rk_1$ were increased after especially 3 times of steaming processes. Interestingly, in black ginseng were prepared by 9 times steaming processes, the content of ginsenoside $Rg_3$ was 8.20 mg/g, approximately 18 times higher than that (0.46 mg/g) in red ginseng. In addition, the ratio of the protopanaxadiol group and protopanaxatiol group (PD/PT) were increased from 1.9 to 8.4 due to increasing times of steamming process.

  • Purpose: We examined the prevalence of anemia, annual screening for anemia, and treatment of anemia with iron among children with inflammatory bowel disease (IBD). Methods: A retrospective study of U.S. pediatric patients with IBD was performed in the MarketScan commercial claims database from 2010-2014. Children (ages 1-21) with at least two inpatient or outpatient encounters for IBD who had available lab and pharmacy data were included in the cohort. Anemia was defined using World Health Organization criteria. We used logistic regression to determine differences in screening, incident anemia, and treatment based on age at first IBD encounter and sex. Results: The cohort (n=2,446) included 1,560 Crohn's disease (CD) and 886 ulcerative colitis (UC). Approximately, 85% of CD and 81% of UC were screened for anemia. Among those screened, 51% with CD and 43% with UC had anemia. Only 24% of anemia patients with CD and 20% with UC were tested for iron deficiency; 85% were iron deficient. Intravenous (IV) iron was used to treat 4% of CD and 4% UC patients overall and 8% of those with anemia. Conclusion: At least 80% of children with IBD were screened for anemia, although most did not receive follow-up tests for iron deficiency. The 43%-50% prevalence of anemia was consistent with prior studies. Under-treatment with IV iron points to a potential target for quality improvement.

  • The aim of this study is to evaluate the effect of yeast extract (YE) and salicylic acid (SA) on the expression of curcuminoid-biosynthesis genes (CzDCS and CURS1-3), and accumulation of curcumin in Curcuma zedoaria cell cultures. The results showed that, in cells treated with YE or SA, the expression levels of curcuminoid genes were 1.14- to 3.64-fold higher than the control (untreated cells), in which the YE exhibited a stronger effect in comparison with SA. Curcumin accumulation also tended to be similar to gene expression, curcumin contents in YE- or SA-treated cells were 1.61- to 2.53-fold higher than the control. The SA treatment at the fifth day of culture stimulated the curcumin accumulation and expression in all four genes compared to that at the beginning. While the YE treatments gave different results, the CzCURS1 and CzCURS3 genes were expressed strongly in cells that were treated at the beginning. However, the CzDCS and CzCURS2 genes showed the opposite expression pattern, they were activated strongly in the treatments at day five of the culture. However, the content of curcumin reached its maximum value on the fifth day of culture in all investigations.

  • Sorafenib, originally identified as an inhibitor of multiple oncogenic kinases, induces ferroptosis in hepatocellular carcinoma (HCC) cells. Several pathways that mitigate sorafenib-induced ferroptosis confer drug resistance; thus strategies that enhance ferroptosis increase sorafenib efficacy. Orphan nuclear receptor estrogen-related receptor γ (ERRγ) is upregulated in human HCC tissues and plays a role in cancer cell proliferation. The aim of this study was to determine whether inhibition of ERRγ with DN200434, an orally available inverse agonist, can overcome resistance to sorafenib through induction of ferroptosis. Sorafenib-resistant HCC cells were less sensitive to sorafenibinduced ferroptosis and showed significantly higher ERRγ levels than sorafenib-sensitive HCC cells. DN200434 induced lipid peroxidation and ferroptosis in sorafenib-resistant HCC cells. Mechanistically, DN200434 increased mitochondrial ROS generation by reducing glutathione/glutathione disulfide levels, which subsequently reduced mTOR activity and GPX4 levels. DN200434 induced amplification of the antitumor effects of sorafenib was confirmed in a tumor xenograft model. The present results indicate that DN200434 may be a novel therapeutic strategy to re-sensitize HCC cells to sorafenib.

  • In this study, AA1060/Alumina composites were fabricated by combined stir casting and accumulative press bonding (APB). The APB process was repeated up to six press bonding steps at 300Ċ. As the novelty, potential dynamic polarization in 3.5Wt% NaCl solution was used to study the corrosion properties of these composites. The corrosion behavior of these samples was compared and studied with that of the annealed aluminum alloy 1060 and versus the number of APB steps. So, as a result of enhancing influence on the number of APB process, this experimental investigation showed a significant enhancement in the main electrochemical parameters and the inert character of the Alumina particles. Together with Reducing the active zones of the material surfaces could delay the corrosion process. Also, at higher number of steps, the corrosion resistance of composites improved. The sample produced after six number of steps had a low corrosion density in comparison with high corrosion density of annealed specimens. Also, the scanning electron microscopy (SEM), was used to study the corrosion surface of samples.

  • Background: Recognizing the seriousness of the misuse and abuse of medical narcotics, the South Korean government introduced the world's first narcotic management system, the Narcotics Information Management System (NIMS). This study aimed to explore the recent one-year opioid prescribing patterns in South Korea using the NIMS database. Methods: This study analyzed opioid prescription records in South Korea for the year 2022, utilizing the dispensing/administration dataset provided by NIMS. Public data from the Korean Statistical Information Service were also utilized to explore prescription trends over the past four years. The examination covered 16 different opioid analgesics, assessed by the total number of units prescribed based on routes of administration, type of institutions, and patients' sex and age group. Additionally, the disposal rate for each ingredient was computed. Results: In total, 206,941 records of 87,792,968 opioid analgesic units were analyzed. Recently, the overall quantity of prescribed opioid analgesic units has remained relatively stable. The most prescribed ingredient was oral oxycodone, followed by tapentadol and sublingual fentanyl. Tertiary hospitals had the highest number of dispensed units (49.4%), followed by community pharmacies (40.2%). The highest number of prescribed units was attributed to male patients in their 60s. The disposal rates of the oral and transdermal formulations were less than 0.1%. Conclusions: Opioid prescription in South Korea features a high proportion of oral formulations, tertiary hospital administration, pharmacy dispensing, and elderly patients. Sustained education and surveillance of patients and healthcare providers is required.

  • 학생들 간에 사용되고 있는 각종 약물 남용에 관한 실태와 문제점을 알아보기 위하여 1989년 3월 15일부터 3월 29일 사이에 부산 시내에 위치한 인문계 실업계, 남 녀 고등학교 각각 1개교씩 총 4개교의 학생 2,411명을 대상으로 지난 1년간 약물 남용실태를 설문조사한 결과를 요약하면 다음과 같다. 대상학생들의 24.4%가 흡연경험이 있었고, 현재 피우는 학생은 11.6%였으며, 실업계 학생이 인문계보다 더 많았다. 안정제, 최면제, 각성제를 제외한 모든 약물의 약명 파악률은 90% 이상이었고, 지난 1년간 복용경험자 비율은 진통제, 소화제, 자양강장제가 70~80% 수준이었고 각성제는 15.6%, 안정제는 1.4%, 최면제는 0.5%, 본드 1.4%, 신나 0.5%였다. 약물 사용 경험자중에서 매일 복용 혹은 사용하고 있는 자의 비율은 진통제 7.7%(145명), 소화제 6.2%(118명), 자양강장제 5.2%(96명), 안정제 5.9%(2명), 각성제 5.0%(19명), 마약류 2.8%(1명)였으나 최면제와 본드의 매일 사용자는 없었다. 이로 미루어 볼때 고등학생은 비마약성 약물의 남용이 심각하다고 하겠다. 약물을 치료목적 이외에 사용한 학생은 남 녀 각각 진통제 8.4%, 6.5%, 소화제 20.7%, 14.7%, 자양강장제 65.4%, 55.5%였으며 마약류는 우울할 때나 호기심으로 쓰는 율이 높았다. 특히 각성제는 대부분 공부를 위하여 사용되고 있는 것으로 나타나 입시제도의 심각성이 지적되고 있다. 구입 장소별로는 마약류, 본드, 신나는 구멍가게나 행상, 친구에게서 구입률이 가장 높았고, 그 이외의 약품은 약국과 의료기관에서의 구입률이 높았다. 흡연자가 비흡연자에 비하여 모든 약물을 월등히 많이 사용하고 있었으며, 특히 마약류의 사용은 흡연과 아주 밀접한 연관성이 있었다. 대상 학생들의 약물의 이름을 알고 있는 비율은 높으나, 약물을 타당한 목적(신체적, 정신적 건강향상)에 사용하지 않는 경우가 많았고, 약물의 처음 사용시기가 중학시절(14~15세)이 많았으며 호기심에서 사용한 율이 높아기 때문에 약물남용의 부작용과 의존성에 대한 경각심을 일찍부터 고취시켜 줄 필요가 있다고 판단되어 국민학교 교육과정에서부터 약물 남용예방을 위한 보건교육 및 홍보가 시급하다고 하겠다. 이와 함께 학생들의 금연에 관한 교육 및 홍보가 우선되어야 할 것이다. 또한 약물을 약국, 구멍가게 등에서 쉽게 구입할 수 있었다는 사실로 보아 약물 통제를 위한 규제를 검토 보완해야 하며, 의약 분업의 조속한 실시가 필요한 것으로 생각된다.

  • (E)-3-Phenyl-1-(2-pyrrolyl)-2-propenone (PPP) is a pyrrole derivative of chalcone, in which the B-ring of chalcone linked to ${\beta}$-carbon is replaced by pyrrole group. While pyrrole has been studied for possible Src inhibition activity, chalcone, especially the substituents on the B-ring, has shown pharmaceutical, anti-inflammatory, and anti-oxidant properties via inhibition of NF-${\kappa}B$ activity. Our study is aimed to investigate whether this novel synthetic compound retains or enhances the pharmaceutically beneficial activities from the both structures. For this purpose, inflammatory responses of lipopolysaccharide (LPS)-treated RAW264.7 cells were analyzed. Nitric oxide (NO) production, inducible NO synthase (iNOS) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) mRNA expression, and the intracellular inflammatory signaling cascade were measured. Interestingly, PPP strongly inhibited NO release in a dose-dependent manner. To further investigate this anti-inflammatory activity, we identified molecular pathways by immunoblot analyses of nuclear fractions and whole cell lysates prepared from LPS-stimulated RAW264.7 cells with or without PPP pretreatment. The nuclear levels of p50, c-Jun, and c-Fos were significantly inhibited when cells were exposed to PPP. Moreover, according to the luciferase reporter gene assay after cotransfection with either TRIF or MyD88 in HEK293 cells, NF-${\kappa}B$-mediated luciferase activity dose-dependently diminished. Additionally, it was confirmed that PPP dampens the upstream signaling cascade of NF-${\kappa}B$ and AP-1 activation. Thus, PPP inhibited Syk, Src, and TAK1 activities induced by LPS or induced by overexpression of these genes. Therefore, our results suggest that PPP displays anti-inflammatory activity via inhibition of Syk, Src, and TAK1 activity, which may be developed as a novel anti-inflammatory drug.
