[Method] With Triarrhena lutarioriparia as materials, samples were collected from April 2012 to November 2012 to explore monthly biomass changes and degradation and saccharification of Triarrhena lutarioriparia. [Result] Plant height was improving upon time; holocellulose and cellulose contents were increasing with dry weight of shoot system increasing and achieved the peak at 78.1% and 40% in September. It can be concluded that NaOH pre-treatment efficiency is better, when Triarrhena lutarionparia was treated with 2% NaOH at 100 ℃ for 20 min and reducing sugar yield achieved 178,42 mg/g. [Conclusion] Triarrhena lutarioriparia can be materials for ethyl alcohol production and the optimal harvest time is from middle September to middle October.展开更多

Here, we demonstrate an unexpected finding that high doses of α-GC exacerbated, rather than ameliorated, EAE. Similar results were observed when MOG35.ss-specific T cells treated with high-dose α-GC were transferred into naive syngeneic recipient mice. Further study showed that high doses of a-GC directly enhance the Thl7 and Thl re- sponse by activation of CD4＋CD44＋ memory T cells through phosphorylation of STAT3 and activation of NF-kB. Un- like the activation of iNKT cells by low doses of a-GC, high doses of a-GC directly interacted with CDld expressed on T ceils and activated Thl7 and Thl cells. Furthermore, antigen-presenting cells （APCs） predominantly express CDldl, whereas the majority of CD4~ T cells express CDld2. Knockdown of CDldl or CDld2 gene expression by RNAi interfered with the activation of iNKT or Thl7/Thl cells, respectively. Therefore, α-GC treatment could im- prove or worsen EAE by engaging either APCs or Thl7/Thl cells depending on the dose used.展开更多

Pitting of fruit was done manually and KMS （0.2%） was added for bleaching. The fruit was pretreated using 4 levels of CaCl2 （Co = 0%, C1 = 1%, C2 = 1.5%, C3 = 2%） and stored in jars for 4 weeks. Thereafter, application of colour was done using Erythrosine （0.05%） followed by dipping pitted fruits in sugar syrup for 24 hours. The samples were treated with 4 levels of citric acid （To = 0%, Tl = 1%, T2 = 1.5%, T3 = 2%） and then concentrated subsequently till desired TSS of 70~ Brix was attained. The samples were dried in cabinet drier at 80 ±20 ℃till constant moisture was attained. The product was packed in polyethene pouches and stored under ambient storage conditions. Results revealed that there was gradual increase in reducing sugars （%）, total sugars （%） during storage while as moisture content （%） decreased. The product developed was found economically profitable and viable for commercial production.展开更多
