The rates of “”infrequently”" or “”never”" responses combined together ranged from 51% to 86% for the various key items.
Conclusion: The overwhelming majority of the referees do not verify, by their own independent analysis, key items related to methodology and statistical analysis of submitted systematic reviews and meta-analyses.”
“BACKGROUND: An emerging innovation for the treatment of polluted air consists in using a liquid-solid biphasic system, in which the sequestering phase contains inert polymer beads. The different polymers tested here for this purpose were; Hytrel (R) G3548L, Hytrel (R) G4078W, styrene butadiene copolymer, 28% and 31%, silicone
rubber, PEBAX (R) 2533, and rubber tires. The selection of the most effective polymer(s) first requires a determination AZD9291 mouse of the uptake of the pollutants by the solid phase in terms of key polymer properties such as partition coefficient, diffusion coefficient and biodegradability.
RESULTS: A significant difference was found in the uptake levels of alpha-pinene from the gas phase for the different polymers tested. Based on partition coefficient measurements,
relatively non-polar polymers such as Kraton (R) tend to uptake alpha-pinene better than polar ones, such as Hytrel (R). A reduction in the partition coefficient of alpha-pinene into polymers in the presence of water has also been observed. It was also proven that the tested polymers are not biodegradable.
CONCLUSIONS: IWR-1-endo price The uptake of alpha-pinene by the different polymers
tested was determined and it was shown that such polymers could be used for air pollution control. Furthermore, their non-biodegradability justifies their use as absorbents. This paper provides a new opportunity to work with biofilters (BFs)/biotrickling filters (BTFs) using polymers as a sequestering phase. (C) 2010 Society of Chemical Industry”
“Objectives: To systematically review the check details literature on the use of probiotics in pregnancy and their impact on maternal outcomes.
Methods: Online databases were searched in April 2012 using the following terms to identify eligible studies: “”probiotics”", “”pregnancy”", “”maternal outcomes”" and “”metabolism”". Primary outcomes of selected studies were maternal fasting glucose during pregnancy and rates of gestational diabetes mellitus (GDM). Secondary outcomes were rates of pre-eclampsia, maternal inflammatory markers and lipid profiles and gestational weight gain. Studies whose primary outcomes were bacterial vaginosis, pre-term delivery and infant atopy were excluded. Only English-language articles were included. The limited number of eligible studies and varying outcomes precluded formal meta-analysis of these data.
Results: Initially, 189 articles were identified and screened. Seven articles met inclusion criteria and are included in the present review.
