Alternative sources of fish oil(FO)are one of the maj.r problems in aquaculture;therefore,the goal of the present study was to examine insect(black soldier fly larvae)oil(BSLO)as a potential replacer of fish/s oy oil in j.venile rainbow trout(initial average weight of 32±0.15 g)*** diets were formulated wherein FO(control diet)was completely replaced with either soybean oil(SO)or BSLO,and an additional BSLO-based diet supplemented with 1.5%bile acid(BSLO+BA)were fed to the fish for 10 *** performance of the BSLO fed group was similar(P>0.05)to that of the FO and SO fed groups,howeve r,the fish fed BSLO+BA diet registered the lowest growth(P0.05)affect the maj.r nutrient content of whole-body,however,the fatty acid composition of the muscle and liver was influenced(P<0.05),with the highest 14:0,16:0,and total saturated fatty acid detected in BSLO or BSLO+BA fed trout compared to the others(P<0.001).No significant diffe rences were observed in eicosapentaenoic acid+docosahexaenoic acid(EPA+DHA)or total n-3 polyunsaturated fatty acid(PUFA)content in muscle among the groups,whereas,the highest EPA:DHA and n-3:n-6 ratios were detected in the FO *** expression for fatty acid binding protein(fabp),fatty acid synthase(fas),and△5 desaturase in the liver was lower in FO(P<0.05),while BSLO+BA registered the highest△6 expression(P=0.006).Supplementation of BA in the BSLO diet increased superoxide dismutase(SOD)and catalase(CAT)activities compared to the other groups(P<0.05).In conclusion,BSLO could serve as a substitute for FO and SO in rainbow trout diet without negatively impacting growth performance,whole-body composition and nutrient retention,and modulate the expression of fatty acid metabolism-related genes in rainbow trout.

Drought and Grazing Effects on Oklahoma Phlox (Polemoniaceae, <i>Phlox oklahomensis</i>)

引用

American j.urnal of Plant Sciences 2013年第6期4卷 9-13页

作者： Tim L. Springer Stacey A. Gunter ronald j. Tyrl Paul F. Nighswonger Department of Biology Northwestern Oklahoma State University Alva USA. Department of Botany Oklahoma State University Stillwater USA United States Department of Agriculture Agricultural Research Service Southern Plains Range Research Station Woodward Oklahoma USA

Oklahoma phlox (Phlox oklahomensis Wherry) is endemic to Butler, Chautauqua, Comanche, Cowley, and Elk Counties of Kansas and Woods and Woodward Counties of Oklahoma. The species comprises populations of a few scattered individuals to several hundred in mixed-grass prairie sites in Oklahoma where cow-calf production is the common agricultural enterprise. It has successfully withstood periods of short-term drought (1 to 4 years) under light to moderate continuous stocking rates (41 to 52 animal unit days per hectare). Under heavy continuous stocking rates and/or prolonged drought, populations of P. oklahomensis tend to decrease in size and number and may disappear in some localities. Prolonged heavy stocking rates and drought will disrupt the reproductive cycle, severely limiting seed production and recruitment of new individuals to populations. During drought periods, livestock managers should use lighter stocking rates or deferred grazing to ensure rapid recovery of all prairie plants, including P. oklahomensis, once the drought ends. This recommendation would likely sustain prairie sites during long-term (longer than 10 years) droughts as well.

Study on the performance of the micropile-mechanically stabilized earth wall

j.urnal of Mountain Science 2018年第4期15卷 825-844页

The Micropile-Mechanically Stabilized Earth(MSE) wall, specially designed for mountain roads, is proposed to improve the MSE wall local stability, global stability and impact resistance of roadside barriers. Model tests and the corresponding numerical modeling were conducted to validate the serviceability of the Micropile-MSE wall and the reliability of the numerical method. Then, a parametric study of the stress and deformation of Micropile-MSE wall based on the backfill strength and interfacial friction angle between backfill and backslope is conducted to evaluate its *** test results indicate that the surcharge-induced horizontal earth pressure, base pressure and lateral displacement of the wall panel of Micropile-MSE wall decrease. The corresponding numerical results are nearly equal to the measured values. The basic failure mode of MSE wall in steep terrain is the sliding of backfill along the backslope, while A-frame style micropiles are capable of preventing the sliding *** maximum resultant displacement can be decreased by 6.25% to 46.9% based on different interfacial friction angles, and the displacement canbe reduced by 6% ~ 56.1% based on different backfill strengths. Furthermore, the reduction increases when the interfacial friction angle and internal friction angle of backfill decrease. In addition, the lateral displacement of wall panel, the deformation of backfill decrease and the tension strain of geogrid obviously, which guarantees the MSE wall functions and provides good conditions for mountain roads.

Disulfiram’s Antineoplastic Effects on Ovarian Cancer

引用

j.urnal of Cancer Therapy 2015年第14期6卷 1196-1205页

Obj.ctive: Aldehyde dehydrogenase (ALDH) enzymatic activity identifies ovarian cancer stem-like cells. We investigated the antineoplastic activity of the ALDH inhibitor Disulfiram on bulk ovarian cancer cells and CD133+/ALDH+ cancer stem-like cells. Study Design: Ovarian cancer cell lines, human ovarian surface epithelial cells, and mesenchymal stem cells were treated with increasing concentrations of Disulfiram and/or Cisplatin in vitro. Treated cells were assessed for viability or FACS-analyzed for either percentage of ovarian cancer stem-like cells or induction of apoptosis. Disulfiram’s impact on cancer stem-like cells was tested in vitro using tumor sphere formation assays and in vivo using tumor initiation assays with in vitro-treated A2780 cells in NSG mice. Finally, Disulfiram’s in vivo activity was assessed versus CD133+/ALDH+ cell-initiated tumor xenografts. Results: Disulfiram demonstrated antineoplastic activity against multiple ovarian cancer cell lines. While Disulfiram had limited in vitro toxicity against human ovarian surface epithelial cells or mesenchymal stem cells (IC50 of ~15 μM and >30 μM, respectively), its antineoplastic activity against cell lines was comparable to Cisplatin (IC50 ~1.5 μM). Disulfiram-mediated cell death was due, at least in part, to induction of apoptosis. Disulfiram activity was additive with chemotherapy. Disulfiram demonstrated selective depletion of CD44+ cells but not the CD133+ cancer stem-like cells. Disulfiram had no therapeutic impact on tumor initiation studies or in vivo therapy of whole cell line or stem cell-initiated tumor xenografts. Conclusions: In biologically relevant concentrations, Disulfiram has clear antineoplastic activity against ovarian cancer cells in vitro. Disulfiram selectively depleted CD44+ but not CD133+ ovarian cancer stem-like cells in vitro. However, Disulfiram had no significant activity in vivo. Thus, improved and more selective ALDH inhibitors may be required to target ovarian cancer s
