K E Vagnoni,E Lopez-Cruz,M Carranza et al.
K E Vagnoni et al.
Experimental induction of intestinal barrier dysfunction (e.g., inflammation and hyperpermeability) has been shown to induce a systemic inflammatory response and reduce productivity in lactating dairy cows. Because numerous natural situatio...
Effects of lysophosphatidylcholine on the oxidative burst response, inflammatory cytokine secretion, and Escherichia coli killing in polymorphonuclear neutrophils isolated from Holstein heifer calves [0.03%]
溶血磷脂酰胆碱对去除细胞核的中性粒细胞氧化爆发反应、炎症因子释放及杀灭大肠杆菌的影响
