Structural analysis and biological activity of cell wall polysaccharides extracted from Panax ginseng marc
No full textGinseng marc is a major by-product of the ginseng industry currently used as animal feed or fertilizer. This fibrous, insoluble waste stream is rich in cell wall polysaccharides and therefore a potential source of ingredients for functional food with health-promoting properties. However, the extraction of these polysaccharides has proved problematic and their exact composition remains unknown. Here we have analysed the composition, structure and biological activity of polysaccharides from ginseng root, stem and leaf marc fractionated using a chelator and alkali solutions. The pectic fraction has been extracted from root marc in high abundance and can activate the production of interleukine-1α and the hematopoietic growth factor by RAW 264.7 murine macrophage cells, which are important immune regulators of T-cells during inflammatory responses and infection processes. Our study reveals the potential to increase the value of ginseng marc by generating carbohydrate-based products with a higher value than animal feed.Jing Li, Damao Wang, Xiaohui Xing, Ting-Jen Rachel Cheng, Pi-Hui Liang, Vincent Bulone, Jeong Hill Park, Yves S.Y.

The Effects of a Syntax-Focused Reading Intervention on Middle-School Students' Syntactic Knowledge
Full text linkSyntactic knowledge, the implicit and explicit knowledge of syntax, is a necessary�" but often overlooked�" component of proficient reading (e.g., Deacon & Kieffer, 2018). Though some research exists on effective syntactic instruction, such as sentence combining (Neville & Searls, 1985; Wilkinson & Patty, 1993), researchers have called for additional investigations (e.g., MacKay et al., 2021). The purpose of this quasi-experimental, mixed methods study was to explore the effectiveness of a syntax-focused reading intervention on middle-school students' syntactic knowledge, in comparison with an alternate condition group. In this study, which took place over nine weeks, 49 sixth graders in a Literacy Support class were assigned to the syntax-focused reading intervention group or the alternate condition group receiving comprehension strategy instruction. The author analyzed the quantitative data using ANCOVA tests with performance on two measures of syntactic knowledge as the outcome variables. The results indicated that there was no significant difference in students' overall performance on the two measures of syntactic knowledge. However, students in the syntax-focused reading intervention group performed significantly better on items in one measure that targeted knowledge of appositive phrases. This finding suggested that students may have used their explicit knowledge of appositive phrases, learned in the syntax-focused reading intervention, to determine the meaning of unknown words in connected text. Qualitative analyses of individual and focus group semi-structured interviews conducted with six students from both groups ( n = 12) suggested that the syntax-focused reading intervention was effective at developing students' metalanguage and strategies for breaking apart sentences, which ultimately supported their syntactic knowledge
Evolutionary Analysis of Subsurface Microbial Community in Taiwan Chelungpu Fault Zone
No full text本研究以台灣車籠埔斷層鑽探計畫(TCDP)所採得之207m、462m、739m、1033m及1287m深度的岩心樣本，進行活動造山帶微生物群落結構之研究、探討其與環境因子之相關性並推測微生物的代謝活動。針對16S rRNA 基因序列進行PCR增幅放大，建構不同深度的細菌和古細菌16S rRNA基因之分子資料庫。將樣本序列與Geneank或RDP database進行比對，以相似度99%定義集結之OTUs，建構親緣關係樹。並使用生態多樣性指數分析細菌的群落結構。研究結果得知，細菌組獲得319條序列，可集結為66群相異的OTUs。各個深度的岩心皆以Proteobacteria門之細菌為主，其中隸屬β-proteobacteria綱之OTU_b001與OTU_b106分別在不同深度樣本中佔優勢，亦存在較為少量的Actinobacteria、Bacteroidetes和Firmicutes三門之細菌，顯示在淺層地下的微生物族群，仍以好氧或兼性好氧之異營代謝活動為主。此外，砂岩樣本之細菌多樣性均高於頁岩樣本，而來自淺部卓蘭層之樣本的多樣性又大於深部錦水頁岩層，顯示此區細菌種類的分佈，主要受到岩性、孔隙度、營養源和地質分層所控制，而深度的影響不甚明顯。古細菌族群則僅在462m和1287m兩岩心樣本中發現，共獲得4個OTUs，其三隸屬於Crenarchaeota門，另一則為Euryarchaeota門之成員，推測古細菌族群之發現，可能與適應深部地層與斷層活動所產生之高熱環境有關。Taiwan Chelungpu-fault Drilling Project (TCDP) is to probe Chelunpu fault zone that triggered Chi-Chi earthquake five years ago. The materials retrieved during coring were used for analysis of microorganism community structure and to investigate the interaction between microorganism and environment as well as prediction of bacterial metabolic function. Sample DNA were extracted from five core samples of 207m, 462m, 739m, 1033m, and 1287m depth below surface, and small-subunit rRNA gene (16S rDNAs) were amplified by PCR using primers specific to the archaea and bacteria domains. The PCR products were cloned and sequenced. Sequence analysis showed 66 bacteria operational taxonomic units (OTUs) from 319 clone sequences and 4 archaea OTUs from 102 clone sequences while using 99% similarity OTU definition. The bacteria 16S rDNA clone libraries were primarily composed of Proteobacteria, especially β-proteobacteria, with minor Actinobacteria, Bacteroidetes, and Firmicutes members. All core samples were dominated by either OTU_b001 or OTU_b106. The above-mentioned results exhibit that shallow subsurface microorganism mainly use obligate aerobic or facultative aerobic heterotrophic metabolism. In addition, archaea were only observed from 462m and 1287m core samples with sequence related to thermophilic species belonging to Crenarchaeota and Euryarchaeota. Diversity index analysis shows the distribution of bacterial species was influenced mainly by lithological characteristics, porosity, and nutrition source rather than depth in this study.中文摘要…………………………………………………………… 1

Reliance on individuating information and stereotypes in impression formation: the diagnosticity and judgment task model of person perception
No full textThis dissertation proposes and tests the diagnosticity and judgment task model of person perception. This decision tree model of reliance on stereotypes and individuating information in impression formation makes a priori predictions regarding in what situations perceivers will rely on individuating information, in what situations they will rely on stereotypes (i.e., category information), and in what situations they will rely on both sources of information. The central tenet of the model is that the diagnosticity (i.e., relevance, usefulness) of the individuating information and the type of judgment task jointly influence reliance on stereotypes and individuating information in stereotype-relevant target evaluations. In the present research, the model’s two main a priori hypotheses were tested: (1) In the presence of highly diagnostic individuating information and category information, perceivers should rely exclusively on individuating information in target evaluations, regardless of the judgment task at hand; and (2) in the presence of somewhat diagnostic information and category information, perceivers should rely exclusively on individuating information in trait ratings, but on stereotypes and individuating information in occupational suitability judgments and target-relevant predictions. The first hypothesis was supported, but the second was not. These results are discussed in the context of previous relevant research.Ph.D.Includes bibliographical referencesby Rachel Sarah Rubinstei
