Escherichia coli 16S-like ribosomal RNAs from
eubacterial, archaebacterial and eukaryotic organisms have
several universally conserved sequence zones which are
proposed to be single-stranded. A clear function for all
of these regions has not yet been defined. To evaluate the
roles of these sequence zones in protein synthesis,
knowledge of their...
Crosses between four near isogenic lines for height reducing genes
Rht₁ and Rht₂ and one agronomically superior dwarf line, including
generations through F₃ with reciprocal backcrosses constituted the
experimental materials. Mean, range and standard deviation values for
eleven traits pertaining to the different generations were obtained.
Heterosis and inbreeding depression...
This study identified new compounds with pest control activities. The two sources of candidates that were followed here were the main heartwood extract of Alaska Yellow Cedar (AYC) constituents and several semi-synthetic counterparts. Five compounds were isolated and identified for the first time in AYC heartwood in this research: two...
BackgroundEpidemiological evidence suggests that arsenic (As) exposure during pregnancy may reduce infant birth weight. One significant source of As exposure is diet; thus, As may indirectly affect infant growth by mediating the effect of maternal diet on birth weight (BW). This study evaluated the potential mediating effect of As in...
Exposure to arsenic early in life has been associated with increased risk of several chronic diseases and is believed to alter epigenetic programming in utero. In the present study, we evaluate the epigenome-wide association of arsenic exposure in utero and DNA methylation in placenta (n = 37), umbilical artery (n...
BACKGROUND: Chronic exposure to arsenic is associated with skin lesions. However, it is not known whether reducing arsenic exposure will improve skin lesions.
OBJECTIVE: We evaluated the association between reduced arsenic exposures and skin lesion recovery over time.
METHODS: A follow-up study of 550 individuals was conducted in 2009-2011 on...
Submarine glacial landforms in fjords are imprints of the dynamic behaviour of marine-terminating glaciers and are informative about their most recent retreat phase. Here we use detailed multibeam bathymetry to map glacial landforms in Petermann Fjord and Nares Strait, northwestern Greenland. A large grounding-zone wedge (GZW) demonstrates that Petermann Glacier...
Soils in household environments in low- and middle-income countries may play an important role in the persistence, proliferation, and transmission of Escherichia coli. Our goal was to investigate the risk factors for detection, survival, and growth of E. coli in soils collected from household plots. E. coli was enumerated in...
