The purpose of this article was to investigate the current state of studies on clinical trials of acupuncture treatment for Alzheimer's disease using neuroimaging method. We searched for clinical trials of acupuncture treatment for Alzheimer's disease(AD) and mild cognitive impairment(MCI) using neuroimaging method in the MEDLINE (Pubmed) database on March 18, 2020. Once the online search was finished, studies were selected manually by the inclusion criteria. Finally, we analyzed the characteristics of selected articles and reviewed the neural substrates of acupuncture treatment in AD. Total ten studies were included in this study. The most frequently applied modality for AD was functional MRI. The most frequently selected acupoints for AD were KI3, LR3 and LI4. One of studies showed that acupuncture treatment could improve the symptoms of MCI. Through the analysis, we demonstrated that neuroimaging method could capture the neural substrates associated with AD. Moreover, acupuncture may induce differential response according to the disease status. Finally, real acupuncture could produce more extensive activation/deactivation than sham acupuncture. We hope that neuroimaging method can contribute to the clinical research of acupuncture treatment for AD through large-scale RCT and diverse imaging modality.

Low-level laser therapy including laser acupuncture (LLLT/LA) has been widely used for non-specific chronic low back pain (NCLBP). However, there is no critically appraised evidence of its potential benefits. This study aimed to evaluate the effectiveness of LLLT/LA for NCLBP. There were 12 databases (MEDLINE, CENTRAL, EMBASE, KoreaMed, KMBASE, KISS, NDSL, KISTI, OASIS, CNKI, CiNII, J-stage) searched for randomized controlled trials using LLLT/LA for NCLBP up until June 2019. The primary outcome was pain intensity and functional status/disability due to NCLBP. A random-effects meta-analysis was conducted on 20 studies involving 1,323 participants. LLLT/LA showed a significant positive effect on pain relief scores compared with sham treatments (SMD -0.51, 95% CI: -0.88 to -0.13; χ2 = 31.12, I2 = 74%). Alone, the therapy showed a significant positive effect on function/disability scores (30 participants, MD -11.90, 95% CI: -17.37 to -6.43). As an add-on treatment, it showed a significant positive effect on pain relief (80 participants, MD -5.10, 95% CI: -9.31 to -0.88; χ2 = 28.99, I2 = 97%) and improved function/disability scores (120 participants, MD 5.44, 95% CI: 2.19 to 8.68; χ2 = 4.07, I2 = 75%). Among 20 studies, 9 studies reported no adverse events and 1 study reported mild adverse events. LLLT/LA may be an alternative or add-on treatment for NCLBP.

나노포장은 나노물질 첨가에 따라 항균성, 가스 및 자외선 차단성과 같은 기능성이 향상된다는 장점이 부각되면서 오랫동안 개발되어 왔다. 하지만 최근들어 이러한 나노물질들이 식품과 직접적으로 접촉되면서 식품으로 이행되어 식품과 함께 섭취될 수 있기 때문에 안전하지 않을 수 있다는 논란이 있다. 독일, 스페인, 영국 등의 많은 유럽 국가들에서는 이러한 문제에 대한 빠른 대처를 위해 2000년대 중반부터 또한 우리나라에서는 2014년부터 나노물질 적용 포장재에서 나노물질의 이행에 대한 연구를 수행하고 있다. 나노물질별, 환경별(온도, 시간), 식품모사용매 또는 식품 유형별에 따른 나노물질의 이행에 대한 연구결과를 바탕으로 향후 안전관리를 위한 방안과 가이드라인 등이 마련되어야 한다.

This study looked through the text mining analysis to check the status of the virtual assistant service, and explore the needs of consumers, and present consumer-oriented directions. Trendup 4.0 was used to analyze the keywords of AI services in Online News and social media from 2016 to 2020. The R program was used to collect consumer comment data and implement Topic Modeling analysis. According to the analysis, the number of mentions of AI services in mass media and social media has steadily increased. The Sentimental Analysis showed consumers were feeling positive about AI services in terms of useful and convenient functional and emotional aspects such as pleasure and interest. However, consumers were also experiencing complexity and difficulty with AI services and had concerns and fears about the use of AI services in the early stages of their introduction. The results of the consumer review analysis showed that there were topics(Technical Requirements) related to technology and the access process for the AI services to be provided, and topics (Consumer Request) expressed negative feelings about AI services, and topics(Consumer Life Support Area) about specific functions in the use of AI services. Text mining analysis enable this study to confirm consumer expectations or concerns about AI service, and to examine areas of service support that consumers experienced. The review data on each platform also revealed that the potential needs of consumers could be met by expanding the scope of support services and applying platform-specific strengths to provide differentiated services.

Livestock species experience several stresses, particularly weaning, transportation, overproduction, crowding, temperature, and diseases in their life. Heat stress (HS) is one of the most stressors, which is encountered in livestock production systems throughout the world, especially in the tropical regions and is likely to be intensified due to global rise in environmental temperature. The gut has emerged as one of the major target organs affected by HS. The alpha- and beta-diversity of gut microbiota composition are altered due to heat exposure to animals with greater colonization of pathogenic microbiota groups. HS also induces several changes in the gut including damages of microstructures of the mucosal epithelia, increased oxidative insults, reduced immunity, and increased permeability of the gut to toxins and pathogens. Vulnerability of the intestinal barrier integrity leads to invasion of pathogenic microbes and translocation of antigens to the blood circulations, which ultimately may cause systematic inflammations and immune responses. Moreover, digestion of nutrients in the guts may be impaired due to reduced enzymatic activity in the digesta, reduced surface areas for absorption and injury to the mucosal structure and altered expressions of the nutrient transport proteins and genes. The systematic hormonal changes due to HS along with alterations in immune and inflammatory responses often cause reduced feed intake and production performance in livestock and poultry. The altered microbiome likely orchestrates to the hosts for various relevant biological phenomena occurring in the body, but the exact mechanisms how functional communications occur between the microbiota and HS responses are yet to be elucidated. This review aims to discuss the effects of HS on microbiota composition, mucosal structure, oxidant-antioxidant balance mechanism, immunity, and barrier integrity in the gut, and production performance of farm animals along with the dietary ameliorations of HS. Also, this review attempts to explain the mechanisms how these biological responses are affected by HS.

Pleurotus species are commercially essential mushrooms and widely cultivated throughout the world. The production of Pleurotus mushrooms alone accounts for around 25% of that total cultivated mushrooms globally. In America and Europe, Pleurotus species are considered specialty mushrooms, whereas, in Korea, their cultivation is economically profitable, and it is one of the highly consumed species. Pleurotus species are predominantly found in tropical forests and often grow on fallen branches, dead and decaying tree stumps, and wet logs. Biographical studies have shown that the Pleurotus genus is among the more conspicuous fungi that induce wood decay in terrestrial ecosystems worldwide due to its formidable lignin-modifying enzymes, including laccase and versatile peroxidases. Pleurotus species can be grown easily due to their fast colonization nature on diversified agro-substrates and their biological efficiency 100%. Pleurotus mushrooms are rich in proteins, dietary fiber, essential amino acids, carbohydrates, water-soluble vitamins, and minerals. These mushrooms are abundant in functional bioactive molecules, though to influence health. Pleurotus mushrooms are finding unique applications as flavoring, aroma, and excellent preservation quality. Apart from its unique applications, Pleurotus mushrooms have a unique status delicacy with high nutritional and medicinal values. The present review provides an insight into the cultivation of Pleurotus spp. using different agro-waste as growth substances paying attention to their effects on the growth and chemical composition.

Purpose: Health literacy is a significant determinant of health and health behaviors such as cancer screening. Despite its significance, there are limited instruments available to assess health literacy targeting Koreans. The purpose of this study was to test the psychometric properties of Korean translation of a validated health literacy instrument in cancer screening-Korean version of assessment of health literacy in breast and cervical cancer screening (K-AHL-C). Methods: A total of 555 women aged 20~65 participated in the online survey study. Of 52 items addressing five domains included in the original version, we focused on 36 items addressing three key domains closely associated with cancer screening: familiarity, health navigation, and comprehension. Results: During content validation, two items from the health navigation domain were removed, yielding 34 items. Using Rasch analysis and confirmatory factor analysis, we found the evidence of construct validity of K-AHL-C. The Korean version was also significantly correlated with measures of Functional Health Literacy scale, cancer prevention behaviors, and subjective health status, suggesting convergent validities respectively. Finally, K-AHL-C had acceptable reliability coefficients (α) ranging from 0.71 to 0.92 for each domain and the total scale. Conclusion: These psychometric properties support the K-AHL-C is a valid and reliable instrument for measuring Koreans' health literacy in cancer screening. Also it is expected to use the instrument to detect breast and cervical cancer early and improve the screening rate, and ultimately to contribute to the promotion of women's health and women's health nursing practice.
