小花棘豆(Oxytropis glabra DC)是新疆分布最广泛、危害最严重的毒草,动物大量采食后会造成中毒.其中中毒动物的繁殖机能下降明显.国内外研究表明,小花棘豆主要毒性成分苦马豆素可通过抑制α-甘露糖苷酶(AMA)的活性而发挥毒性作用.现有研究表明小花棘豆中毒动物睾丸出现细胞空泡变性和坏死等病理变化,但尚未有关于AMA在睾丸中分布和表达的报道.本研究通过探讨小花棘豆中毒对小鼠睾丸AMA活性
养鸡生产特别是肉鸡饲养,疫苗接种是饲养管理中关键的一环,但在短时间内需要接种十几种疫苗,其疫苗免疫应激强度很大,临床实践中常常发生免疫应激事件,甚至是免疫麻痹,诱发家禽疾病.这与免疫功能抑制和细胞凋亡有着极为密切的关系.脾脏作为机体的重要免疫器官,其功能状态的正常与否,直接关系到到机体整体免疫情况的好坏,因此,检测脾淋巴细胞的凋亡与增殖情况是从客观上判断机体整体免疫功能好坏的一个重要手段.将90只
Ethyl levulinate(EL)has been considered as a new liquid biofuel candidate.One-pot production of EL from wasted biomass was investigated in this study.Furfural residues(FRs),the abundant wasted biomass
Biodiesel production catalyzed by free lipase has been drawing attention for its lower cost and faster reaction rate compared to immobilized lipase.It has been found that free lipase NS81006 could eff
In this paper,we proposed an alternative way to produce biodiesel from palm oils.Different Ni2P/SiO2 catalysts were synthesized using the thermal decomposition of metal hypophosphite precursors.The ca
Simultaneous saccharification and fermentation(SSF)of very high gravity(VHG)cassava mash,containing 329.07 g·L-1 of dry cassava flour,was used for ethanol production.The mash was hydrolized to maltode
The paper investigated the localized economics of a lignocellulosic ethanol production technology developed by NREL[1] in China,based on nth–plant project costs and 2013 prices.The results show that t
In this work,a novel subcritical n-butane extraction(SNBE)of castor oil from cold pressed cake was investigated.On the basis of single-factor experiments,it was observed that the decrease of moisture
In recent years,energy crisis and environmental issues such as greenhouse effect,global warming,etc.has roused peoples concern.Biodiesel,as renewable energy,has attracted much attention to deal with s
In order to research physical and chemical properties of blend diesel fuel,EL,biodiesel and n-butanol was taken as the key additive.Some experiments was studied based on China National Standards and C
