Gallstones from 24 female patients were subjected to quantitative chemical analysis. Two main categories of stones were identified:
(1) Ten cholesterol stones with 93.38% cholesterol and only 0.17% bilirubin. (2) Mixed stones with cholesterol below 65%.
They were sub-divided in two groups: (a) Six stones having 0.5% bilirubin and (b) Eight stones having 0.5% bilirubin. The
calcium of cholesterol and mixed stones was comparable while phosphorus contents in cholesterol stones were low by over 30%
in mixed stones. 相似文献

Conclusion Assessing teacher effectiveness is a complex issue with social and historical dimensions. Assessment of teacher effectiveness
was an alien concept in ancient and medieval India. The teacher's moral authority, scholarship, wisdom and role in shaping
the lives of the youth and the society was unquestionable. The place of the teacher ('the Guru’) was always considered much
higher than that of the parents.

Currently, world is facing a global outbreak causing a pandemic threat known as COVID-19. This infectious disease is triggered by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Gut microbiota harbours multi species community with a strong impact on host immune homeostasis. However, our knowledge about this gut microbiota and its symbiotic relationship with immune activation in association with SARS-CoV-2 is limited. Unbalanced bacterial flora with too many opportunistic infections can shift immune system towards a cascade of inflammatory responses leading to multi organ damage. This review will highlight immune-regulation via various mechanisms in SARS-CoV-2 infection. Diet has an unbelievable influence on gut microbiome that allows a new state of homeostasis to be reached through timing, frequency and duration of intake. This review article focuses on gut, lung microbiota and immunomodulation with specific attention on immune activation by gut microbiota. 相似文献

Timeline generation systems are a class of algorithms that produce a sequence of time-ordered sentences or text snippets extracted in real-time from high-volume streams of digital documents (e.g. news articles), focusing on retaining relevant and informative content for a particular information need (e.g. topic or event). These systems have a range of uses, such as producing concise overviews of events for end-users (human or artificial agents). To advance the field of automatic timeline generation, robust and reproducible evaluation methodologies are needed. To this end, several evaluation metrics and labeling methodologies have recently been developed - focusing on information nugget or cluster-based ground truth representations, respectively. These methodologies rely on human assessors manually mapping timeline items (e.g. sentences) to an explicit representation of what information a ‘good’ summary should contain. However, while these evaluation methodologies produce reusable ground truth labels, prior works have reported cases where such evaluations fail to accurately estimate the performance of new timeline generation systems due to label incompleteness. In this paper, we first quantify the extent to which the timeline summarization test collections fail to generalize to new summarization systems, then we propose, evaluate and analyze new automatic solutions to this issue. In particular, using a depooling methodology over 19 systems and across three high-volume datasets, we quantify the degree of system ranking error caused by excluding those systems when labeling. We show that when considering lower-effectiveness systems, the test collections are robust (the likelihood of systems being miss-ranked is low). However, we show that the risk of systems being mis-ranked increases as the effectiveness of systems held-out from the pool increases. To reduce the risk of mis-ranking systems, we also propose a range of different automatic ground truth label expansion techniques. Our results show that the proposed expansion techniques can be effective at increasing the robustness of the TREC-TS test collections, as they are able to generate large numbers missing matches with high accuracy, markedly reducing the number of mis-rankings by up to 50%. 相似文献

Although the educational experiences of South Asian Muslim women have been studied, little is known regarding the role of technology and its effects on education in this population. This study explores the use of information and communication technologies (ICT) in British Muslim girls’ schools and its effect on learning. It uses primary data from semi-structured interviews with 14–19-year-olds in three Islamic faith schools. Template analysis was used to identify emerging themes. Participants had access to a wide range of technologies and applications; however, access was often limited to classroom settings. Participants also used subject-specific resources available from learning platforms, although this was not consistent across schools and subjects. The participants felt that the range of resources was limited because of their gender and religion, and wanted greater access to ICT, and more online collaboration and social communication. A didactic approach to instruction was prevalent and for many, exacerbated a ‘digital disconnect’. Our findings suggest that Islamic faith schools reinforce lack of home ICT use. The current didactic approach highlights differences with the student-centred pedagogical techniques of early Qur’anic schools. This study encourages a discussion of the challenges of open access to information, religious freedoms and ensuring equality of learning. 相似文献

Objective
Scandix pecten-veneris L. is a less studied wild edible herb and is considered an extinct plant species in many parts of the world. This study was designed to evaluate its phytochemical composition and biological potential of S. pecten-veneris L.Methods
Phytochemicals including alkaloids, flavonoids, polyphenols, and tannins were determined in extracts of S. pecten-veneris. Antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), while reducing power was tested by ferric reducing/antioxidant power (FRAP) assay. Antimicrobial activity against seven bacterial and four fungal strains was evaluated using agar well diffusion assay. Enzymes inhibition study was performed for urease, phosphodiesterase-I, and catalase-II.Results
S. pecten-veneris showed moderate antiradical activity and reducing potential of hydroxyl radicals to about 20% of the initial value. The antioxidant activity of various extracts of S. pecten-veneris showed a linear correlation with total phenolic contents in the order of water>n-butanol>chloroform>ethyl acetate>methanol extracts. S. pecten-veneris leaves showed the highest inhibitory activity against Staphylococcus aureus while the highest antifungal activity was observed against Candida albicans. The plant extract was most potent against urease enzymes but showed moderate activity against phosphodiestrase-I and carbonic anhydrase-II.Conclusions
Our data demonstrate that in addition to its culinary uses, S. pecten-veneris has good medicinal potential and hence could be used for treating some specific health ailments.38.
The South Asian diaspora and its impact on the lives of dispersed communities is a complex phenomenon finding expression in a range of issues and debates. However, the nature and scale of the challenges and issues vary in each case and context, and even over generations. These issues become more sensitive and poignant when underpinned by cultural and belief systems. This paper debates the impact of dominant discourses and values on schooling choices and the related concerns to explore issues linked to girls’ education among Pakistani diaspora in England, drawing on relevant literature and the evidence from a recent study of single-sex schooling. It argues that multiple emotional, social, cultural, historical, political, economic and other affiliations influence the patterns of behaviour and the terms of civic engagement in the adopted country leading to a struggle over meanings and competing positions over values and practices that are fluid and dynamic. 相似文献

M-learning is gaining popularity in formal and informal education, both in developed and developing countries. Specifically it can be an effective tool to overcome digital divide in developing countries. The success of m-learning at tertiary level depends on the perception of students towards this form of learning. A scientific approach was used in this study to explore the critical factors responsible for m-learning adoption among university students. The findings of this study, based on 628 valid survey responses, have both theoretical and practical implications for researchers and policy-makers. 相似文献
