It is classically thought that increases in hemoglobin mass (Hbmass) take several weeks to develop upon ascent to high altitude and are lost gradually following descent. However, the early time course of these erythropoietic adaptations has not been thoroughly investigated and data are lacking at elevations greater than 5000 m, where the hypoxic stimulus is dramatically increased. As part of th...

Progressive cerebral infarction (PCI) is associated with high rates of mortality and disability. Many studies have shown that Dl-3n-butylphthalide (NBP) is effective against acute ischemic stroke. The administration of NBP can result in an increased number of capillaries in the ischemic region, promote the establishment of collateral circulation, protect the mitochondria, and narrow the infarct...

The present study was conducted to investigate whether dietary essential oils could affect growth performance, relative organ weights, cecal microflora, immune responses and blood profiles of broiler chickens fed on diets containing different nutrient densities. A total of eight hundred-forty 1-d-old male broiler chicks were randomly allotted into twenty-eight pens (7 pens per treatment, 30 chi...
