Eleven types of nuts and seeds were analyzed to determine their energy (326-733 mg), moisture (1.6-18.3 mg), carbohydrate (8.8-70.9 mg), protein (4.9-30.5 mg), lipid (2.5-69.8 mg), and ash (1.2-5.5 mg) contents per 100 g of sample. Energy content was highest in pine nuts (733 mg/100 g), carbohydrate level was highest in dried figs (70.9 mg/100 g) and protein was highest in peanuts (30.5 mg/100 ...

Carbonate concretions can form as a result of organic matter degradation within sediments. However, the ability to determine specific processes and formation temperatures of particular concretions has remained elusive. Here, we employ concentrations of carbonate-associated sulfate (CAS), SCAS and clumped isotopes (along with more traditional approaches) to characterize the nature of concretion ...

Natural dark mink kit were fed a diet supplemented with 0, 25, 50, 100 or 200 ppm Cu from CuSO4 . 5H2O for 153 or 357 d. The shorter term Cu supplementation had no significant beneficial or adverse effects on mink body weight gains or hemoglobin or hematocrit concentrations, although plasma Cu concentrations were slightly elevated in the mink fed added Cu. Liver Cu concentrations were significa...

A heavy metal ion sensor was constructed by cross-linking melanin onto the gold electrode of quartz crystal microbalance (QCM). A mercury ion sensitivity of 518+/-37 Hz/ppm was observed, a substantial increase in sensitivity compared to previous reports of 10-50 Hz/ppm with the limit of detection at 5 ppb. Detection of other metal ions including Sn(2+), Ge(4+), Li(+), Zn(2+), Cu(2+), Bi(3+), Co...

Mintrex Zn, Mintrex Cu, and Mintrex Mn organic trace minerals contain 16% Zn, 15% Cu, and 13% Mn with 80, 78, and 76% 2-hydroxy-4-(methylthio)butanoic acid (HMTBA) by weight as the organic ligand, respectively. Our objective was to determine if HMTBA from Mintrex was fully available as a Met source. In experiment 1, thirty-six broilers (7 to 10 d old) were orally gavaged with methyl-(14)C-label...

in order to investigate the impact of foliar zn application in reducing the negative effects of water stress on bean growth and yield, a field experiment was carried out in the research field of ilam university in 2011. the experiment was arranged in split factorial based on a randomized complete block design with three replications. the experimental factors were water stress including water wi...

Soil samples in Moryayla village located 156 km northeast of Erzurum and Cu mineralization area around it were collected randomly. In these samples, 20 taken order to investigate the metals found pollution limits sources that cause this pollution. The geochemical analyzes (Cd, Cr, Cu, Ni, Pb, Zn Fe) soil made evaluated with parameters. calculation parameters, enrichment factor (EF); geoaccumula...

Two studies were conducted to compare the availability of trace minerals offered to Brahman-crossbred heifers in either grain- or molasses-based supplements. Heifers were randomly assigned to bahiagrass pastures of equal size (n = 3 and 2 heifers/ pasture with 6 and 4 pastures/treatment for Experiment 1 and 2, respectively). Two supplements were formulated using corn and cottonseed meal (DRY) o...

Three experiments were conducted to determine the effects of phytase, excess Zn, or their combination in diets for nursery pigs. In all experiments, treatments were replicated with five to seven pens of six to seven pigs per pen, dietary Ca and available P (aP) levels were decreased by 0.1% when phytase was added to the diets, excess Zn was added as ZnO, a basal level of 127 mg/kg of Zn (Zn sul...

OBJECTIVES Zinc (Zn) is related to insulin synthesis, storage, and secretion. This study demonstrates the effects of Zn supplementation in donor rats on the outcomes of islet transplantation. METHODS Donor rats received 3 different regimens of dietary Zn supplementation for 2 weeks before undergoing pancreas donation: a standard diet containing Zn at 50 ppm (control), 1 ppm (low-Zn group) or ...
