Assessment of ferritin and lead levels in children living in an informal urban settlement in Kenya
No full textBackground: Childhood lead exposure from recycling used lead-acid batteries (ULAB) in unregulated areas is a significant cause of lead toxicity, particularly in low and middle-income countries. This study aimed to assess the proportion of children with increased blood lead levels (BLLs) in an informal settlement where ULAB recycling occurs.
Methodology: This was a descriptive study conducted in Nairobi county, Kenya. Children aged 6 months to 7 years were recruited after obtaining written informed consent, completion of a questionnaire and collection of samples for complete blood count, ferritin, and lead analysis.
Results: Out of 215 children, 17 (8.0%) had BLLs ≥ 5 μg/dL. There was a weak negative correlation between BLLs and ferritin (rs(211) = −0.147, P = .032).
Conclusion: Our study confirms the presence of increased BLLs in children residing in the study area. Relevant authorities should legislate on safe ULAB disposal to protect the population from toxic effects
AAC Cranford cranberry dry bean
No full textAAC Cranford is an early maturing cranberry dry bean (Phaseolus vulgaris L.) cultivar with high yield, an upright determinate bush (Type I) growth habit and large seed size. Currently, dry bean cultivars in the cranberry bean market class are only commercially grown in Manitoba and Ontario primarily due to their late maturity. Therefore, AAC Cranford with its early maturity and high yield potential will enable growers to commercially produce cranberry bean in Alberta and Saskatchewan.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

AAC GN963 great northern dry bean
No full textAAC GN963 is a high yielding great northern dry bean (Phaseolus vulgaris L.) cultivar with an upright, indeterminate bush (Type II) growth habit, early maturity and a large seed size. Lodging resistance of AAC GN963 is slight improvement compared to AAC Whitehorse, a great northern bean cultivar with predominant commercial acres under irrigation in southern Alberta. The canning and cooking quality attributes of AAC GN963 were similar to the check cultivars AAC Whitehorse and Resolute. AAC GN963 is well suited for commercial production under irrigation in Alberta and Saskatchewan.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

AAC Y073 yellow dry bean
No full textAAC Y073 is a high yielding yellow dry bean (Phaseolus vulgaris L.) cultivar with a partially upright, determinate bush (Type I) growth habit, early maturity, and large seeds with a bright yellow seed coat. Large, bright yellow seeds of AAC Y073 is an improvement over the current check cultivar CDC Sol. AAC Y073 was developed at the Agriculture and Agri-Food Canada, Lethbridge Research and Development Centre, Lethbridge, AB, and is well suited for commercial production under irrigation in Alberta and Saskatchewan.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

AAC Y012 and AAC Y015 yellow dry bean
No full textAAC Y012 and AAC Y015 are high yielding, early maturing yellow dry bean (Phaseolus vulgaris L.) cultivars with a determinate bush growth habit (Type I), improved seed coat colour and partial field resistance to white mould. AAC Y012 and AAC Y015 were developed at the Agriculture and Agri-Food Canada (AAFC) Research and Development Centre, Lethbridge, AB. AAC Y012 and AAC Y015 are suitable for irrigated wide row production in Alberta and Saskatchewan.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

AAC PT600 pinto dry bean
No full textAAC PT600 is a high yielding pinto dry bean (Phaseolus vulgaris L.) cultivar with an upright, indeterminate bush with short vine (Type IIa) growth habit, early maturity and large seed size. AAC PT600 had significantly improved lodging resistance and partial field resistance (i.e., avoidance) to white mould compared to both Island and AAC Expedition, pinto bean cultivars currently grown in southern Alberta. The base colour of seed coat of AAC PT600 was light brown, similar to AAC Expedition, and was better than Island which had a dark brown base seed coat. The canning and cooking quality attributes of AAC PT600 were similar to the check cultivar Island. AAC PT600 is well suited for commercial production under irrigation in Alberta and Saskatchewan.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

AAC Expedition pinto dry bean
No full textAAC Expedition is a high yielding pinto dry bean (Phaseolus vulgaris L.) cultivar with a semi-upright, indeterminate bush (Type IIb) growth habit, large seed size, low percentage of hard seed and bright seed coat colour. Improved seed quality traits especially bright seed coat colour and low percentage of hard seeds after soaking, and high yield potential of AAC Expedition will make it a preferred pinto bean cultivar for commercial production. AAC Expedition developed by Agriculture and Agri-Food Canada (AAFC) Research and Development Centre, Lethbridge, AB, is well suited for commercial production under irrigation in Alberta and Saskatchewan.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

In situ precipitation of amorphous calcium phosphate nanoparticles within 3D porous collagen sponges for bone tissue engineering
No full textAmorphous calcium phosphate (ACP) plays an important role in biomineralization within the three-dimensional (3D) collagen network in human hard tissues, and exhibits osteoconductivity. Porous collagen sponges coated with ACP nanoparticles could be considered as potential scaffolds for use in bone tissue engineering. In this study, such composite materials were fabricated via homogeneous ACP precipitation using a supersaturated calcium phosphate (CaP) solution. Homogeneous ACP precipitation was induced in situ within the sponges by a temperature-controlled coating process composed of two steps. In the first step, the CaP solution was cooled to 4 °C to suppress precipitation until the solution penetrated fully into the sponge's internal pores. In the second step, the CaP solution was warmed up to 25 °C with continuous shaking to induce ACP precipitation within the sponges. The resulting sponges were therefore coated with ACP nanoparticles on their inner and outer surfaces. A simulated body fluid (SBF) test indicated osteoconductivity of the collagen sponges coated with ACP nanoparticles. Further, ACP-coated collagen sponges immobilizing basic fibroblast growth factor (bFGF) were fabricated using the CaP solution supplemented with bFGF. The fabricated sponges allowed the sustained release of bFGF in a culture medium and enhanced proliferation of osteoblastic MC3T3-E1 cells. Such ACP-coated collagen sponges have the potential to be used as scaffolds in bone tissue engineering if pursued for further in vitro and in vivo studies
