Abstract Reconstructing intermediate and bottom‐water temperature in the Arctic Ocean is key for understanding paleoclimatic phenomena, such as region's interactions with warm Atlantic waters, stratification, sea‐ice dynamics. However, benthic proxy archives are sparse throughout circle compared to lower latitudes. Trace‐element ratios (E/Ca) derived from ostracodes, a group of bivalved microsc...

Abstract Assessment of the microbial impact on mineral dissolution is crucial for a predictive understanding basic (Ca, Mg bearing) silicate weathering and associated CO 2 consumption, bioerosion, storage in basaltic rocks. However, there are controversies about mechanism effect, which ranges from inhibiting via nil to accelerating. Here we studied diopside interaction with heterotrophic bacter...

this study was carried out to investigate the effects of 1, 25-dihydroxycholecalciferol (1, 25 (oh)2 d3) and root hydroalcoholic extract of withania somnifera (ws) root on performance, mineral retention, bone mineralisation and mechanical characteristics of broiler chicks. treatments were arranged factorially (2×3×2) consisted of a positive control with adequate ca and a negative control diet (...

Increasing available Mg in crested wheatgrass (Agropyron spp•) could reduce the incidence of grass tetany (hyponsagnesemia) in ruminants glazing this forage. Raisins the Mg levels might be done through genetic processes if enough variation in ion concentration existed in the Agropyrons. The purpose of this study was to determine the genetic variation in Mg, Ca, and K concentrations in 2 crested...

The major nuclease from Mycoplasma penetrans has been purified to homogeneity. The enzyme seems to be present as a membrane-associated precursor of 50 kDa and as a peripheral membrane monomeric polypeptide of 40 kDa that is easily removed by washing of cells with isotonic buffers and in the aqueous phase upon Triton partitioning of Triton X-114-solubilized protein. The 40-kDa nuclease was extra...
