The effect of ascorbic acid (AA) and butylated hydroxyanisole (BHA) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for AA and BHA) in diet containing 1 ppm total aflatoxin (AF: 76.45% AFB1, 10.52% AFB2, 9.89% AFG1 and 3.14% AFG2). A total of 300 day-old broiler chicks were divided into ten treatment groups (T1=control; T2...
Ascorbic acid (AA) as a vitamin and neuromodulator is present in most parts of CNS such as nucleus accumbens shell (Acbsh). This study evaluates the effect of intra-nucleus accumbens shell injection of AA on spatial learning and memory. 35 adult male Wistar rats (220-270 g) were divided into 5 groups: control (intact), sham AA (injected normal saline as AA vehicle) as well as 3 groups of AA (12...
Kepler’s Harmonice Mundi includes a mysterious arrangement of polygons labeled Aa, in which many of the polygons have fivefold symmetry. In the twentieth century, solutions were proposed for how Aa might be continued in a natural way to tile the whole plane. I present a collection of variations on Aa, and show how it forms one step in a sequence of derivations starting from a simpler tiling. I ...
