Comparison of two microdiffusion methods used to measure ionizable fluoride in cow's milk
(2011)
Two microdiffusion methods for measuring ionizable fluoride in cows' milk have been compared. The comparison includes diffusion time, amount of fluoride in spiked and unspiked milk samples and the effect of aluminium as ...
Study on the microstructure of African wild silk cocoon shells and fibers
(2012-01)
Silk fibers and cocoon shells from four African wild silkmoths Gonometa postica, Anaphe panda, Argema mimosae and Epiphora bauhiniae-were studied to gain insight into the structure-property-function relations and potential ...
The palaeo-lake Suguta and its importance for understanding lake level fluctuations in the East African Rift System
(University of Nairobi, 2010)
We studied the most recent dry-wet-dry cycle in the presently arid Suguta Valley in the Northern Kenya Rift where a 300-m-deep lake has formed during the so-called African Humid Period (AHP, 14.8-5.5 ka BP). Hydromodeling ...
Steady rifting in northern Kenya inferred from deformed Holocene lake shorelines of the Suguta and Turkana basins.
(University of Nairobi, 2012-05-15)
A comparison of deformation rates in active rifts over different temporal scales may help to decipher variations in their structural evolution, controlling mechanisms, and evolution of sedimentary environments through time. ...
ASXL1 mutations promote myeloid transformation through loss of PRC2-mediated gene repression
(2012)
Recurrent somatic ASXL1 mutations occur in patients with myelodysplastic syndrome, myeloproliferative neoplasms, and acute myeloid leukemia, and are associated with adverse outcome. Despite the genetic and clinical data ...
Effect of serum lipoproteins on stereoselective halofantrine metabolism by rat hepatocytes
(2012)
Experimental hyperlipidemia has shown to decrease cytochrome P450 3A4 and 2C11 expression and to increase liver concentrations and the plasma protein binding of halofantrine (HF) enantiomers. The present study examined the ...
Relapse-specific mutations in NT5C2 in childhood acute lymphoblastic leukemia
(2013)
Relapsed childhood acute lymphoblastic leukemia (ALL) carries a poor prognosis, despite intensive retreatment, owing to intrinsic drug resistance. The biological pathways that mediate resistance are unknown. Here, we report ...
A stage-wise approach for the analysis of multi-environment trials.
(University of Nairobi, 2012)
Plant breeders and variety testing agencies routinely test candidate genotypes (crop varieties, lines, test hybrids) in multiple environments. Such multi-environment trials can be efficiently analysed by mixed models. A ...
Differential transcription of two highly divergent gut-expressed Bm86 antigen gene homologues in the tick Rhipicephalus appendiculatus
(2011)
The transcriptional control of gene expression is not well documented in the Arthropoda. We describe transcriptional analysis of two exceptionally divergent homologues (Ra86) of the Bm86 gut antigen from Rhipicephalus ...
