Background There is a strong,bi-directional link between tuberculosis(TB)and undernutrition:TB often causes undernutrition,and undernourished people are more likely to contract TB and experience worse ***,several TB nutritional support programmes exist;however,evidence on their effectiveness is limited and *** study evaluates the effect of a nutritional support programme implemented for people with TB in the Atsimo-Andrefana region,Madagascar in *** this programme,undernourished people with TB[with a body mass index(BMI)of<18.5 kg/m]receive 0.6 L of vegetable oil and 6.0 kg of a soy-wheat blend per month throughout their TB *** We analysed secondary non-governmental organisation data collected between January and Novem-ber 2022 in the Atsimo-Andrefana region,Southern Madagascar,including information on an individual's medical conditions(e.g.,type of TB,treatment outcomes)and nutritional status measured prior to,during,and after comple-tion of treatment(e.g.,height,weight,mid-upper arm circumference).We conducted descriptive analyses of patient baseline characteristics and outcomes to assess the impact of the provided nutritional support on the BMI of people With *** A total of 1310 people with TB were included in the study[9.9%(130)children under the age of 5,32.1%(420)children between 5 and 18 years,58.0%(760)adults].55.4% of children under 5,28.1% of children between ages 5 and 18,and 81.3%of adults were undernourished at treatment initiation.42.3%(55/130)of children under 5 experi-enced severe acute malnutrition at treatment *** the average BMl of adults with TB receiving food support increased over time,from 17.1 kg/m^(2)(interquartile range:15.8-18.3,range:10.3-22.5)to 17.9 kg/m^(2)(interquartile range:16.6-19.1,range:11.9-24.1),most adults remained undernourished even after completing TB *** The current TB nutritional support programme falls short of sufficiently increasing the BM

文物承载着灿烂文明,传承着历史文化,是全人类的宝贵遗产。由于文物不可再生的珍贵性,以及最少干预的文物保护基本原则,无损分析技术始终是文物制作工艺研究、劣化机理及保护修复研究中材料分析的最主要技术手段。因此,研发、应用新型无损分析技术是文物保护利用的重要研究方向。近年来,源于遥感领域的便携式地物高光谱仪在文物材料分析中展现出强大应用潜力,并且已在石质古建筑、绘画等文物修复中成功应用。作为一种无需采样的非侵入式光谱技术,便携式地物高光谱仪可在极短时间获取一个涵盖可见光-近红外-短波红外波段(350~2500 nm)的全波段、高分辨率反射光谱。同时,其便携程度很高,对工作环境、光源等无特殊要求,可在野外文物或遗址现场原位使用。此外,在采集光谱数据的同时还可通过遥感技术实现数据的远程传输和分析。上述技术特点使其在文物材料分析中具有独特的应用优势。以光谱技术的基本原理为基础,首先介绍了目前文物材料分析中常用便携式地物高光谱仪的设备型号及其性能指标;其次细致梳理了近十年来其在有机质/无机质文物材料定性和定量分析、文物保护材料分析,以及文物修复原位、实时监测等方面的应用现状;之后深入探讨了谱图预处理的规范和建立标准波谱库等两个影响该技术应用效果的关键问题;最后展望了该技术的发展趋势,预期在脆弱有机质文物分析、多种分析技术联合应用和定量分析研究方面前景广阔。

American Journal of Plant Sciences 2024年第2期15卷 95-109页

作者： Gisele mara Silva Gonçalves Andre Bernardo de Camargo Eisingher Postgraduate Program in Health Sciences Pontifical Catholic University of Campinas (PUC-Campinas) Campinas Brazil

Silymarin, from the fruit of Silybum marianum, is known for its hepatoprotective action. The aim of this study was to review the mechanisms of action of the silymarin phytocomplex to expand the possibilities for its application in human health. The search for published articles was carried out on the CAPES Journals Portal platform, which covers worldwide scientific databases. Publications from 2010 to 2022 were included. Of the 311 articles retrieved, 21 were included. The articles discuss the diversity of silymarin’s applications and the possibility of optimizing its bioavailability using drug delivery systems. Silymarin shows promise in numerous diseases, such as liver, kidney, cardiovascular, respiratory and others. Its antiviral action has been demonstrated in studies and silymarin has the potential to be used as a complementary therapy in the treatment of many diseases, with the expectation that, in the future, it will be used in therapeutic protocols for exclusive use.

The use of cover crops is a promising strategy for influencing the soil microbial consortium,which is essential for the delivery of multiple soil functions(i.e.,soil multifunctionality).Nonetheless,relatively little is known about the role of the soil microbial consortium in mediating soil multifunctionality under different cover crop amendments in dryland ***,we assessed the multifunctionality of soils subjected to four cover crop amendments(control,non-amended treatment;RD,radish monoculture;HV,hairy vetch monoculture;and RDHV,radish-hairy vetch mixture),and we investigated the contributions of soil microbial richness,network complexity,and ecological clusters to soil *** results demonstrated that cover crops whose chemical composition differed from that of the main plant crop promoted higher multifunctionality,and the radish-hairy vetch mixture rendered the highest *** obtained evidence that changes in soil microbial richness and network complexity triggered by the cover crops were associated with higher soil ***,specialized microbes in a key ecological cluster(ecological cluster 2)of the soil microbial network were particularly important for maintaining soil *** results highlight the importance of cover crop-induced variations in functionally important taxa for promoting the soil multifunctionality of dryland Ultisols.
