A study was conducted to evaluate the effects of dietary inorganic and organic trace minerals in two levels of supplementation regarding performance, diarrhea occurrence, hematological parameters, fecal mineral excretion and mineral retention in metacarpals and liver of weanling pigs. Seventy piglets weaned at 21 days of age with an average initial body weight of 6.70 ± 0.38 kg were allotted in...

UNLABELLED Bacteria play important roles in mineral weathering, soil formation, and element cycling. However, little is known about the interaction between silicate minerals and rhizobia. In this study, Rhizobium yantingense H66 (a novel mineral-weathering rhizobium) and Rhizobium etli CFN42 were compared with respect to potash feldspar weathering, mineral surface adsorption, and metabolic acti...

In the present study, models were developed to estimate the altitudinal variation in secondary metabolite contents of Hypericum orientale growing wild in “Güldağı” mountain, Turkey. Aerial parts of flowering 30 individuals were collected at six different altitudes (500, 1150, 1650, 2100, 2720 and 3250 m). Actual secondary metabolite contents of plants were measured by High Performance Liquid Ch...

The role of hepatic intrinsic clearance for metabolite formation from various precursors on subsequent metabolite elimination was was investigated in the once-through perfused rat liver preparation. Two pairs of acetaminophen precursors: [14C] phenacetin-d5 and [3H] phenacetin-do, [14C] acetanilide and [3H] phenacetin were delivered by constant flow (10 ml/min/liver) either by normal or retrogr...

Previous laboratory and pilot clinical trial data suggest that vitamin and/or mineral supplementation may prevent tumor growth in small cell lung cancer. However, rates of supplementation and their major purported clinical effects have never before been studied in patients with small cell lung cancer. This study was undertaken to explore associations between vitamin/mineral supplementation and ...

A new hydroxylated metabolite of tamoxifen, Metabolite Y [frans-1 -(p-/?-hydroxyethoxyphenyl)-1,2-diphenylbut-1-ene] was characterized and subsequently measured by high-per formance liquid chromatography in serum from patients receiv ing normal (10 mg twice daily) and high dose (>150 mg twice daily) tamoxifen therapy for treatment of advanced breast cancer. In normal-dose patients, the serum le...
