Attempts to estimate the effects of dietary cholesterol on serum cholesterol by meta-analysis have not previously included baseline together with added dietary cholesterol in a mathematical model. Mean reported changes in serum cholesterol from 27 studies in which controlled diets were supplied by a metabolic kitchen provided 76 data points, each weighted by the number of subjects in nonlinear ...

Three experiments conducted with weanling pigs evaluated the effects of vitamin E added to the drinking water or diet on plasma and tissue αtocopherol concentrations. When natural or synthetic vitamin E was used, it was added at an IU-equivalent basis, but natural vitamin E was 73.5% (mg basis) of the synthetic vitamin E. Experiment 1 used 18-d-old weanling pigs (n = 120) in a 3 × 2 factorial a...

The following is a list of the major changes since Version 2.0 of the package. Replaced gsvd by cgsvd which has a diierent sequence of output arguments. Removed the obsolete function csdecomp (which replaced the function csd) Deleted the function mgs. Changed the storage format of bidiagonal matrices to sparse, instead of a dense matrix with two columns. Removed the obsolete function bsvd. Adde...

Various fluxing materials are added to technical ceramics in an attempt to lower their sintering temperatures and make their processing economical. The effect of 0·3 wt% Li2CO3 addition on the phase, microstructure, phase transition temperatures and dielectric properties of BaTiO3 was investigated in the present study. The addition of 0·3 wt% Li2CO3 was observed to lower the optimum sintering t...

A total of 160 finishing pigs (PIC 327 × 1050; initially 45.6 kg) were used in an 84-d experiment to evaluate the effects of dietary fat source and feeding duration on growth performance, carcass characteristics, and carcass fat quality. There were 2 pigs per pen with 8 pens per treatment. The 10 dietary treatments were a corn-soybean meal control diet with no added fat and a 3 × 3 factorial wi...

Bacterial reduction of selenate [Se(VI)] to elemental Se [Se(0)] is considered an effective bioremediation technique to remove selenium (Se) from agricultural drainage water. However, the fate of the newly formed Se(0) in aquatic systems is not known when it flows out of the treatment system. A set of laboratory experiments was conducted to determine the fate of the colloidal-particulate Se(0) ...

An experiment was conducted to study the effect of adding crystalline niacin to low-protein diets on pig performance from weaning to market weight. Niacin was added at 0, 3, 9, 27, or 81 ppm to a low-protein test (LPT) diet fortified with crystalline amino acids and at 0 or 81 ppm to a positive control (PC) diet. Pens (four pigs/pen) were the experimental units with 12 and 8 pens per treatment ...

Because latent form of matrix metallopeptidase-9 (proMMP9) levels are positively related to blastocyst development, it was hypothesized that addition during maturation may improve development of heat-stressed oocytes. To test hypothesis, 0, 30 or 300 ng/ml human proMMP9 (hMMP9) was added at 18 h of in vitro maturation (hIVM) to cumulus-oocyte complexes matured at 38.5 or 41.0ºC (first 12 h only...
