Malaria-causing protozoa of the genus Plasmodium have exerted one strongest selective pressures on human genome, and resistance alleles provide biomolecular footprints that outline historical reach these species
In the summer of 1845, under command Sir John Franklin, 128 officers and men aboard Royal Navy ships HMS Erebus Terror sailed into Lancaster Sound entered waters Arctic North America. The goal this expedition was to complete discovery a northwest passage by navigating uncharted area between Barrow Strait Simpson Strait. Franklin his crew spent first winter at Beechey Island, where three crewmen died were buried. September 1846, became stranded in ice off coast King William they remained...
Synchrotron‐based standard X‐ray fluorescence imaging can be a sophisticated tool for mapping distributions of trace elements in archaeological bone; however, thin samples are normally required to achieve high‐spatial‐resolution results. Poorly preserved or fragile challenging measure using this technique, since the production sufficiently section may difficult. We discuss implementation confocal as successful strategy high‐resolution elemental poorly bone. The method additionally facilitate...
A novel X-ray collimating optic enables improved spatial resolution in confocal fluorescence imaging and absorption spectroscopy.
Bone is a dynamic tissue which exhibits complex patterns of growth as well continuous internal turnover (i.e. remodeling). Tracking such changes can be challenging and thus high resolution imaging-based tracer would provide powerful new perspective on bone dynamics. This is, particularly so if detected in 3D. Previously, strontium has been demonstrated to an effective by synchrotron-based dual energy K-edge subtraction (KES) imaging either 2D or The use however, limited very small sample...
Helicobacter pylori is a gram-negative bacterium that colonizes the stomach of nearly half world's population. Genotypic characterization H. strains involves analysis virulence-associated genes, such as vacA, which has multiple alleles. Previous phylogenetic analyses have revealed connection between modern and movement ancient human populations. In this study, DNA was amplified from tissue Kwäday Dän Ts'ìnchi individual. This individual recovered Samuel Glacier in Tatshenshini-Alsek Park,...
To evaluate the feasibility of using non-radioactive barium as a bone tracer for detection with synchrotron spectral K-edge subtraction (SKES) technique.Male rats 1-month old (i.e., developing skeleton) and 8-month skeletally mature) were orally dosed low dose chloride (33mg/kg/day Ba2+) 4weeks. The fore hind limbs dissected imaging in projection computed tomography modes at 100μm 52μm pixel sizes. SKES method utilizes single bent Laue monochromator to prepare 550eV energy spectrum encompass...
Abstract Lead (Pb) has been known to be a cause of human poisoning since ancient times, but despite this, it was widely used metal in the European colonial period. In this study, relationship between Pb exposure and demographic variables ancestry age explored by comparing bone levels individuals that were either African or ancestry, excavated from British Royal Navy hospital cemetery (1793–1822 CE) at English Harbour Antigua, West Indies. More direct comparisons two ancestral groups possible...
Bones represent a valuable biological archive of environmental lead (Pb) exposure for modern and archaeological populations. Synchrotron radiation X-ray fluorescence imaging (SR-XFI) generates maps Pb in bone on microstructural scale, potentially providing insights into an individual's history and, the context bone, biogenic or diagenetic nature its uptake. The aims this study were to (1) examine spatial patterns from samples cadavers compared with observed archaeologically, (2) test...
ABSTRACT A pathological condition, aural atresia, was discovered associated with human remains recovered from a late 19 th ‐century Catholic cemetery 2 km south of Battleford, Saskatchewan, Canada. Aural congenital condition that results in non‐existent external auditory meatus, apparent on the right temporal bone young adult male. complete osteological and contextual assessment, which included use SkyScan 1172 micro‐CT scanner incus recovered, indicated malleus had fused during early...
Bioarchaeology, the sub-discipline of archaeology concentrating on human remains, involves study skeletal tissues to make inferences about lifeways in past. Trace metals such as lead (Pb...
