9 +/- 57.8 d before conception showed a 7.3-g/L increase in change in hemoglobin from baseline compared with those
who initiated supplementation at 26.3 +/- 12.3 d after conception (P = 0.01). Among 146 nonpregnant women, IFA decreased anemia (odds ratio: 0.19; 95% CI: 0.04, 0.95) and improved iron stores (P = 0.001) more than did FA.
Conclusion: Good adherence and initiation of supplementation before conception are needed to reduce anemia during early pregnancy. This trial was registered at www.clinicaltrials.gov as NCT00953134. Am J Clin Nutr 2009; 90: 1295-302.”
“Errors encountered in the capacitance-voltage (C-V) measurements of quantum well (QW) structures are usually attributed to Debye smearing. The other sources from which errors may occur are not well discussed in literature. In this paper we have
highlighted the limits of Selleckchem SBC-115076 C-V measurements on QW structures. Simulations have been carried out through the self-consistent solutions of the Schrodinger and Poisson equations for various band offsets, dopings, and temperatures. This will provide guidelines for suitable design of quantum structures for proper C-V measurements. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3462395]“
“Introduction: p53 codon 72 polymorphism has been reported to be associated with bladder cancer incidence, progression and prognosis, but the association is still under debate. A tentative model was constructed to evaluate the association between p53 codon 72 polymorphism and bladder cancer. Subjects Napabucasin solubility dmso and Methods: In this study, a total of 554 participants were enrolled. The genotyping was carried out using PCR-RFLP and DNA direct sequencing. Results: The genotype distribution of p53 codon 72 polymorphism
was significantly different between bladder cancer patients and controls (p = 0.039). In logistic regression, diagnostic age and genotype Pro/Pro were the risk factors for developing an invasive tumor. A 4.526-fold risk was estimated for the patients with Pro/Pro genotype as opposed to non-Pro/Pro genotype to develop invasive selleck compound tumors. However, the extent of p53 codon 72 polymorphism did not predict bladder cancer prognosis. Conclusions: A conceptual mode was constructed; in addition, the moderating and mediating analysis was also carried out in a structural equation model to resolve possible confounding effects. Taken together, p53 codon 72 polymorphism may be associated with bladder cancer incidence and progression, but not prognosis. Further study is needed to evaluate the usefulness of the constructed model in risk assessment. Copyright (C) 2011 S. Karger AG, Basel”
“A high power narrow line width (38 W, 0.09 nm full width at half maximum) external cavity diode laser is investigated for rubidium spin exchange optical pumping of Xe-129. This tunable photon source has a constant line width, independent of operating power or wavelength within a 1 nm tuning range.
