Design: GW69A This analysis used the most recent data from Demographic and Health Surveys of 19 malaria-endemic countries in sub-Saharan Africa. Survival information of 101,636 singleton live-born infants
from the most recent delivery of ever-married women <= 5 y before each survey was examined. The effect of each potential predictor on neonatal deaths was analyzed by using Cox proportional hazards regression models.
Results: Infants whose mothers received any iron/folic acid supplements and sulfadoxine-pyrimethamine intermittent preventive treatment (SP-IPT(p)) for malaria during pregnancy were significantly protected from neonatal death [hazard ratio (HR): 0.76; 95% CI: 0.58, 0.99]. The protective effect was not significant in mothers who received only iron/folic acid supplements (HR: 0.90; 95% CI: 0.73, 1.12) or only SP-IPT(p) (HR: 1.08; 95% CI: 0.74, 1.57). Among the sociodemographic and birth characteristics, factors that significantly increased the risk of neonatal death included first-born infants, a birth interval of <2 y, maternal age at delivery of >= 30 y, smaller than
average-sized infants, and male infants.
Conclusion: The use of antenatal iron/folic Fosbretabulin supplier acid supplements combined with appropriate intermittent preventive treatment of malaria during pregnancy is an important intervention to reduce neonatal mortality in malaria-endemic regions. Am J Clin Nutr 2010;92:235-43.”
“Novel polyaminophenols, poly-2-[3-thienylmethylene] aminophenol (P-2,3-TP), poly-3-[3-thienylmethylene] phosphatase inhibitor library aminophenol (P-3,3-TP) and poly-4-[3-thienylmethylene] amino phenol (P-4,3-TP), were synthesized by oxidative polycondensation reaction. Metal complexes of P-2,3-TP were also obtained. The structures of synthesized compounds were confirmed by FT-IR, UV-vis, (1)H NMR, and
(13)C NMR techniques. The characterization was made by TG-DTA, DSC, and gel permeation chromatography (GPC) analyses in addition to solubility tests. Electrical conductivities of polymers were measured by four-point probe technique. Fluorescence measurements were carried out in various solutions and optimum concentrations and maximal intensities were determined. The new synthesized polyaminophenols are good candidates for electronic, opto-electronic, and photovoltaic applications due to polyconjugated structures. (C) 2011 Wiley Periodicals, Inc.

“This paper presents an atomistic Green’s function study of phonon transport through a heterogeneous interface between bulk TiC substrates and graphene nanoribbons (GNRs). The force constants that govern the lattice dynamical equations are obtained from first-principles density functional theory (DFT) calculations and then optimized for the Green’s function formulation. Phonon vibrational properties of TiC and GNRs are investigated by lattice dynamics calculations with optimized force constants that correlate well to direct DFT results.
