Pilat (Hymenochaetaceae) Significantly Inhibits the Growth of Sarcoma 180 by Inducing ApoptosisCaifa Chen, Weifa Zheng, Xiaowen Gao et al.Inonotus obliquus (Fr.) Pilat (Hymenochaetaceae) has been widely used as a folk medicine to treat various cancers in Russia, Poland and most of Baltic countries for literally more than four centuries. However, in spite of its therapeutic significance for cancers, this fungus has not been studied systematically for the mechanisms of antitumor activity. In this study, we report the effects … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 1 · 31 Mar 2007 · 21,110 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Context-Free Grammar for Parsing Manipuri LanguageYumnam Nirmal, Utpal SharmaParsing, i.e., identifying the underlying hierarchical structure of natural language expressions is important for several natural language processing applications. In recent times Machine Learning (ML) approaches have been developed for this study for many languages. Most of the effective techniques require an annotated corpus of the language for training and validation. For the Manipuri language of the Tibeto-Burman family, neither … …Journal of Computer Science, Vol. 17, Issue 9 · 9 Oct 2021 · 6,420 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Combined Approach to Improve Supervised E-Learning using Multi-Sensor Student Engagement AnalysisAbdulkareem Al-AlwaniE-learning provides an important means of education which can reach masses irrespective of their locations all over the world. The E-learning systems and platforms have evolved over the years, but E-learning methodologies are still lagging in matching the benefits of teacher-student interaction in a classroom.

Research ArticleOpen accessIn the abstractConformal Mapping of Temperature Variation in Compost HeapJonah Chukwuemeka Agunwamba, Oji Achuka NwokeLaboratory in vessel trapezoidal compost system was designed and constructed. Temperature variation in the compost heap was measured for five days at various depths. Mathematical model for the variation of temperature of the composting process was developed using Conformal Mapping Technique. One of the parameters in the model had two distinct roots, one a positive root and the other negative … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 17 Jun 2016 · 7,347 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordHeterologous Expression and Biochemical Characterization of Lipase from Burkholderia cepacia Lu10-1Yao Zhang, Lu Wang, Yuanda SongEven though lipase genes from a variety of microorganism have been cloned and over-expressed, the prospective lipase resources for commercial production and industry application are still limited. In the present study, a lipase from Burkholderia cepacia Lu10-1 is heterologously over-expressed in Escherichia coli strain BL21(DE3) and purified to homogeneity. The molecular weight of the recombinant lipase from B. cepacia Lu10-1 … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 23 Dec 2017 · 8,765 accessesView PDF Cite
