Title: Ethnomedicinal studies on medicinal plants used by people of Rif, Morocco 题目:摩洛哥里夫人民使用的药用植物的民族医学研究
N. Chaachouay
Medicinal and aromatic plants are a considerable source of active substances which are exploited in the treatment of several diseases. This study was carried out in the Rif (North of Morocco), it aimed to identify medicinal and aromatic plant used by the local people to treat digestive system diseases, together with the associated ethnomedicinal knowledge. Methods: The ethnomedical information collected was from 732 traditional healers using semi-structured interviews, free listing and focus group. Family use value (FUV), use value (UV), plant part value (PPV), fidelity level (FL) and Informant Agreement Ratio (IAR) were employed in data analysis. Medicinal and aromatic plant were collected, identified and kept at the natural resources and biodiversity laboratory, Ibn Tofail University, Kenitra. Results: During the present study 87 medicinal plant species belonging to 43 families has been documented. The most frequent ailments reported were gastric ulcers (IAR = 0.97). The majority of the remedies were prepared from decoction (42.12%). Leaves were the most frequently used plant part (PPV = 0.344) and Thymus saturejoides Coss. (UV = 0.240) was the specie most commonly prescribed by local herbalists. Conclusions: The results of this study showed that people living in the Rif of Morocco are still dependent on medicinal and aromatic plants. The documented plants can serve as a basis for further studies on the regions medicinal plants knowledge and for future phytochemical and pharmacological studies.
药用和芳香植物是活性物质的重要来源,可用于多种疾病的治疗。这项研究是在Rif(摩洛哥北部)进行的,其目的是确定当地人民用于治疗消化系统疾病的药用和芳香植物,以及相关的民族医学知识。方法:采用半结构化访谈法、自由清单法和焦点小组法对732名传统治疗师进行民族医学信息收集。采用家庭使用价值(FUV)、使用价值(UV)、植物部分价值(PPV)、保真度(FL)和知情同意率(IAR)进行数据分析。药用和芳香植物被收集、鉴定并保存在Kenitra Ibn Tofail大学自然资源和生物多样性实验室。结果:本研究共记录到43科87种药用植物。最常见的疾病是胃溃疡(IAR = 0.97)。以煎制为主(42.12%)。使用频率最高的植物部位为叶片(PPV = 0.344)和胸腺。(UV = 0.240)是本地中医最常开的品种。结论:本研究结果表明,生活在摩洛哥Rif地区的人们仍然依赖药用和芳香植物。这些记录的植物可以作为进一步研究该地区药用植物知识和未来植物化学和药理研究的基础。

IoT and Face Recognition based Remote Access System 基于物联网和人脸识别的远程访问系统
Amey Bairolu, Sanjukta Sheth, Binay Hazra, Arpit Rawankar
— There are many security systems available in the market and in thesis, which are stringent and can make things worse in the hour of need as there are many situations which demand customized authentication. These systems either require the visitors to provide details of authenticity, for instance, ID cards, passwords, etc. or require someone to explicitly be near the entrance to manually check the details. There are even some existing security systems which become cumbersome for the owners by seeking permission time and again even when the visitor is a frequent one. This paper, therefore is focused on providing a smart solution, without compromising security, by employing a system which will not only grant access to authorized visitors, but will also allow some expected visitors to walk through the doors and restrict the rest even when there is no one physically present near the entrance or anywhere near the concerned area to manually check on the visitors. This system will therefore solicit permission from the owner only when the visitor is unknown. This remote access system therefore uses face recognition, which is a biometric artificial intelligence based technology, and Internet of Things (IoT) to give access to the known visitors when it recognizes them successfully or to give access to the expected visitors by sending an e-mail to the owner with a picture of the visitor, to let the owner decide whether or not to give access to the visitor even when the owner isn’t anywhere near the entrance. For face recognition, histogram of oriented gradient has been used as it requires lower computational time and lower processing power. To allow the owner to remotely send controlling commands to the raspberry pi, Flask has been used to host a webpage designed solely for the stated purpose, along with serveo that allows remote port forwarding. The system also uses an IoT API (ThingSpeak) to upload the name of the authorized visitors and their time of arrival.
-市场上和论文中有许多安全系统,这些系统很严格,在需要的时候会使事情变得更糟,因为有许多情况需要定制认证。这些系统要么要求访客提供真实性的详细信息,例如身份证、密码等,要么要求有人明确地在入口附近手动检查详细信息。甚至有一些现有的安全系统,对于业主来说,即使访客是常客,也要一次又一次地寻求许可,这变得很麻烦。因此,本文的重点是提供一个智能的解决方案,在不影响安全性的情况下,通过采用一个系统,不仅允许授权的访客进入,而且允许一些预期的访客通过大门,并限制其他人,即使没有人实际出现在入口附近或相关区域附近的任何地方,以手动检查访客。因此,这个系统只会在访问者是未知的情况下征求所有者的许可。因此,这种远程访问系统使用人脸识别,这是一种基于生物识别人工智能的技术,以及物联网(IoT),当它成功识别已知的访客时,可以访问他们,或者通过向主人发送带有访客照片的电子邮件来访问预期的访客,让主人决定是否允许访问访客,即使主人不在入口附近。在人脸识别中,定向梯度直方图的计算时间较短,处理能力较低,因此被广泛采用。为了允许所有者远程发送控制命令到树莓派,Flask被用来托管一个专为声明目的而设计的网页,以及允许远程端口转发的服务器。该系统还使用物联网API (ThingSpeak)上传授权访客的姓名和到达时间。

Highlighting glycosylation ways in Caryophyllaceae saponins by simplex simulation approach 用单纯形模拟方法突出石竹科皂苷的糖基化途径
Asma Hammami, M. Farman, N. Semmar
Glycosylation mechanisms in saponins of Caryophyllaceae plant family were subjected to simulation by statistically exploring variability of 231 chemical structures belonging to four different aglycones: gypsogenin (Gyp), quillaic acid (QA), gypsogenic acid (GA), 16-OH-gypsogenic acid (16-OH-GA). Saponins based on different aglycones were initially characterized by relative glycosylation levels of different carbons. Simulation was initialized by combining the four saponin groups using Scheffe’s mixture design which provides a complete set of N gradual weightings of groups. Combined saponins were randomly and iteratively sampled from different groups by bootstrap technique. For a same combination, saponins were averaged leading to barycentric glycosylation profile. Iterations of the N barycentric profiles and averaging provided a final response matrix of N smoothed glycosylation profiles from which regulation mechanisms of carbons were highlighted in different aglycone-based saponins. Glucose (Glc) was revealed to be widely favored in GA and 16-OH-GA with more target aspect of 28-Glc in 16-OH-GA and relatively shared distribution between C28 (mainly) C3 and C23 in GA. Strong competition for galactose (Gal) was highlighted between C3 and C28 with target aspects to 28-Gal in GA and 3-Gal in (Gyp, QA). Gyp and QA showed higher regulations of pentoses (xylose, Xyl; arabinose, Ara) with more affinity of GA for (3-Ara, 28-Xyl) and 16-OH-GA for (3-Xyl, 28-Ara). These results call for further investments in simulations of glycosylation mechanisms helping for better understanding metabolic aspects of saponins, and encouraging future analytic experiments in the field.
通过统计分析石膏原素(Gyp)、香桐酸(QA)、石膏原酸(GA)、16- oh -石膏原酸(16-OH-GA)四种不同苷元的231种化学结构的变异,模拟了石竹科植物皂苷的糖基化机制。基于不同苷元的皂苷最初通过不同碳的相对糖基化水平来表征。采用Scheffe的混合设计,将四种皂苷组组合,初始化模拟,该设计提供了一套完整的N个逐渐加权组。采用自举法从不同组中随机迭代取样组合皂苷。对于相同的组合,皂苷被平均导致重心糖基化谱。N质心谱的迭代和平均得到了N平滑糖基化谱的最终响应矩阵,从中突出了碳在不同苷基皂苷中的调节机制。葡萄糖(Glc)在GA和16-OH-GA中被广泛偏爱,在16-OH-GA中28-Glc的靶点更多,而在GA中C28(主要是)C3和C23之间的分布相对共享。C3和C28之间对半乳糖(Gal)的激烈竞争突出,目标方面是GA中的28-Gal和GA中的3-Gal (Gyp, QA)。Gyp和QA对戊糖(木糖、Xyl;GA对(3-Ara, 28-Xyl)和(3-Xyl, 28-Ara)具有更强的亲和力。这些结果呼吁进一步投资于糖基化机制的模拟,以帮助更好地理解皂苷的代谢方面,并鼓励未来在该领域的分析实验。
