| The content of insulin-like growth factor 1 (IGF-1) in bovine milk in México is unknown, and high levels could increase the health risk for adult people who ingest milk. The aim of this study was to determine the level of IGF-1 and its relationship with fat content using liquid chromatography with ion trap as a mass detector in milk marketed in Durango, México. During 18 months we analyzed, three times, six lots chosen randomly of whole, reduced-fat, and low-fat milk of three brands. Each sample was pre-treated using cut-off membranes, digested with trypsin, and subjected to liquid chromatography-mass spectrometry. There was a significant difference in the mean concentration of IGF-1 between the brands and types of milk analyzed (Chi square=34.66;... |

| Oat (Avena sativa L.) is a cereal grain, its seeds are rich in nutrients, is consumed as whole grain with health benefits fot humans due to its antioxidants, such as the avenanthtamides (Avns). The contents of Avns 2c, 2f and 2p were evaluated by HPLC in groats and hulls of oat varieties Chihuahua, Cuauhtemoc, Raima and Avemex cultivated in Durango, México. The association of these Avns with protein, fat, crude fiber and ash of oat was also investigated. A 4x2 bifactorial design was used, with the number of varieties and groats ot hulls as factors. Avns contents differed significantly (p<0.05) among oat varieties, groats and hulls. Avemex groats had the highest concentrations of Avns: 3.6±0.7, 3.0±0.5 and 3.3±0.6 mg kg-1 fot 2c, 2f and 2p Avns. Avemex... |
