| 4 | Case Study:Productive Performance and Prediction of Operating Income of Small-Scale Contract Farming of Swine in Lampang,Thailand显示文摘The objective of this study was to examine productive performance and predict factors affecting operating income of small-scale contract farming of swine(SCFS)in Lampang,Thailand.Ten SCFSs were selected by purposive sampling as primary data sources for two consecutive fattening cycles during the year 2015-2017.Data indicated that the SCFS was feeder pig finishing system which herd size(HS)averaged 502 head/farm.The animals consumed approximate 1.59 kg of feed/head/d.The average daily gain(ADG)was 675.22 g/d and feed conversion ratio(FCR)was 2.42.The mean of fattening time(FT)averaged 158 d/cycle.The culling rate(CR)and mortality rate(MR)were 0.17%and 2.50%,respectively.The predicted operating income(POI)was estimated by multiple linear regressions.The equation was:POI=2,700.912+0.027HS–7.119CR–18.225MR+16.885ABW+806.466FI–4.142ADG–420.281FCR–9.719FT(ABW=average body weight;FI=feed intake)with r=0.899,r2=0.808,p-value=0.009.According to stepwise procedure,the potential equation was:POI=323.664FI–9.769MR–22.635 with r=0.837,r2=0.701,p-value=0.000.This predicted equation would benefit as a monitoring index for SCFS to manage their expected operating income and proper farm management to be further profitable and sustainable. | Suntorn Wittayakun Worawut Chainetr Nirundorn Kongngoen Weera Innaree Piyamas Tancharoenrat Ir.Marjuki | 2019 | Journal of Agricultural Science and Technology(A)2019，9，3： | 0 |
| 5 | Tinospora crispa extract inhibits MMP-13 and migration of head and neck squamous cell carcinoma cell lines显示文摘Objective: To investigate the effect of Tinospora crispa(T. crispa) extract on matrix metalloproteinase 13(MMP-13) expression and cell migration. Methods: The cytotoxicity of T. crispa extract was examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay on head and neck squamous cell carcinoma(HNSCC) cell lines. The effect on expression of MMP-13 was analysed by RT-PCR and ELISA. The migration was assessed by wound healing assay. Results: MMP-13 m RNA was highly expressed in the metastatic human HNSCC cell lines, HN22 and HSC-3. T. crispa extract at a concentration of 100.0 μg/m L caused about 50% reduction of cell survival. T. crispa extract at a non-toxic concentration of 12.5, 25.0 and 50.0 μg/m L signii cantly suppressed MMP-13 m RNA expression and secreted MMP-13 in both HN22 and HSC-3. The expression of tissue inhibitors of metalloprotease by HSC-3 cells was attenuated by 25.0 and 50.0 μg/m L of T. crispa extract. Addition of the extract to cells in a wound healing assay showed inhibition of cell migration by HN22 cells. Conclusions: These data suggest that T. crispa could be considered as a potential therapeutic drug to prevent metastasis of HNSCC. | Hataipan Phienwej Ih-si Swasdichira Surattana Amnuoypol Prasit Pavasant Piyamas Sumrejkanchanakij | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，9： | 0 |
