\n\nMethods: Serum bone turnover markers (BTMs), bone specific alkaline phosphatase
(BALP), type 1 procollagen SN-38 mw N-terminal propeptide (P1NP), osteocalcin (OC), and the beta-isomerized C-terminal telopeptide of type 1 collagen (beta-CTx) were measured in 50 adult male DTC patients after 4-week suspension of levothyroxine replacement therapy and 40 matched euthyroid controls. Relationships between parameters of thyroid function (free triiodothyronine, FT3; free thyroxine, FT4; thyroid stimulating hormone, TSH) and the BTMs were studied.\n\nResults: The patients had significantly decreased OC (-37.6%, P<0.001) and beta-CTx (-35.5%, P<0.001) compared with the controls, showing FT3 as the independent
risk factor for OC (R(2)=0.425, P<0.001) and beta-CTx (R(2)=0.124, P<0.001). Partial correlation analysis showed that only FT3 was significantly correlated with OC after controlling FT4 and TSH (r=0.362, P=0.001).\n\nConclusions: DTC patients have moderately decreased bone turnover after short-term suspension of thyroxine suppressive therapy, Selleckchem CFTRinh-172 with serum FT3 concentration as the predominant and independent risk factor.

“The use of low-cost, potential, locally available and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. Sequential Plackett-Burman design (PBD) model was used to screen out the most significant factors and Box-Behnken design (BBD) GSK2126458 in vitro to study the combined effects of interaction between the variables selected by PBD. Second-order polynomial regression model was applied which was statistically validated using analysis of variance. Maximum decolorization 96.25% obtained at pH 6.88, dye concentration 188.01 mg/L and adsorbent dose 0.49 g (dead yeast cells) after 60 min. Kinetic studies showed that the adsorption follows pseudo-second order kinetics and maximum 61% desorption obtained. Negative values of Gibbs free energy change (Delta G(o)) showed that
the adsorption was feasible and spontaneous and negative values of enthalpy change (Delta H-o) confirmed exothermic adsorption. (C) 2012 Elsevier B.V. All rights reserved.”
“A first study on the use of Chilean natural zeolite of different particle sizes (0.5, 1 and 2 mm in diameter) in laboratory-scale batch denitrificant reactors was carried out with the aim of assessing the microbial communities adhered to this material. Molecular techniques such as fluorescence in situ hybridization (FISH) and denaturing gradient gel electrophoresis (DGGE) fingerprints revealed a high microbial diversity with a strong presence of Gammaproteobacteria (70% of the total microorganisms) in reactors with zeolite 0.5 mm in diameter. Archaea were only detected in the reactors with zeolite 1 mm in diameter.
