ABSTRACT

This study examined the low-impact dance intervention on the markers of bone metabolism, cognitive function, and functional fitness of postmenopausal women. Senior women were randomized into low-impact dance (LG) or control group (CG). Three dance sessions weekly were scheduled in the LG for 16 weeks. The markers of bone metabolism, bone composition, Stroop test, and functional fitness were assessed at pre- and post-intervention. The marker of bone formation, some of cognitive function and functional fitness were improved in the LG. The low-impact dance intervention benefited the marker of bone formation, parts of cognitive function and functional fitness.

ABSTRACT

In this study, we developed a novel analysis method based on liquid chromatography/tandem mass spectrometry (LC-MS/MS) to allow the simultaneous identification of 20 coccidiostats in eight matrix categories, including the muscles of chicken, swine, cow, and fish as well as chicken eggs, bovine milk, and porcine viscera. In the pretreatment procedure, acetonitrile/methanol (95:5, v/v) containing 1% formic acid, 5 g of sodium acetate, and 6.0 g of anhydrous magnesium sulfate was used for extraction, followed by a clean-up procedure using n-hexane saturated with ACN to facilitate the elimination of analytes from high lipid samples. Chromatographic separations were achieved using a Poroshell 120SB C18 column and operated with a gradient mobile phase system consisting of methanol (with 0.1% formic acid) and 5 mM ammonium formate, and the MS detection was monitored simultaneously. The method was validated in accordance with the Guidelines for the Validation of Food Chemical Methods by the Taiwan Food and Drug Administration. The limit of quantitation among 8 matrices were 0.5-2 ng g-1. The proposed method proved highly effective in detecting the presence of targeted veterinary drugs, providing a high degree of precision and accuracy over a broad range of matrices.
