The Middle Period of the Atacama oases, North Chile, has been characterized as a time of peace, uniform abundance, and widespread access to exotic materials. In the present work, we test this notion through a comparison of Middle Period human isotopic data (δCco, δ Nco, and δCap) representing two distinct ayllus, Solcor and Tchecar, in the San Pedro de Atacama oases. We employ Bayesian mixture ...

Inferred dietary preference is a major component of paleoecologies of extinct primates. Molar occlusal shape correlates with diet in living mammals, so teeth are a potentially useful structure from which to reconstruct diet in extinct taxa. We assess the efficacy of Dirichlet normal energy (DNE) calculated for molar tooth surfaces for reflecting diet. We evaluate DNE, which uses changes in norm...

a 25 year-old man presented with pain, swelling, and intermittent drainage from distal lateral aspect of his left knee three months after undergoing isolated acl reconstruction with arthroscopic hamstring autograft and endobottom technique. his surgeon at that time tried to eliminate the pathology through arthroscopic wash out in two attempts. however, the pain, edema, and discharge recurred af...

There are reasons to suspect that dietary changes through adult life may modify risk for some cancers. We examined the association of recent and past dietary habits and changes in dietary intake over time with ovarian cancer risk. Long-term nutritional assessment was performed retrospectively in 631 incident cases of invasive epithelial ovarian cancer and in 1174 matched controls (matched by ag...

We develop and test a model to predict the geographic region-of-origin of humans based on the stable isotope composition of their scalp hair. This model incorporates exchangeable and nonexchangeable hydrogen and oxygen atoms in amino acids to predict the delta(2)H and delta(18)O values of scalp hair (primarily keratin). We evaluated model predictions with stable isotope analyses of human hair f...

A semimechanistic model has recently been proposed to explain observed correlations between the H and O isotopic composition of hair from modern residents of the USA and the isotopic composition of drinking water, but the applicability of this model to hair from non-USA and preglobalization populations is unknown. Here we test the model against data from hair samples collected during the 1930s-...

background: dietary diversity score (dds) measurement was used to assessment of diet quality in different disease like cardiovascular disease. one way to improve the cardiovascular patient's ability is cardiac rehabilitation program that include exercise training, nutrition consultation and psychological treatment. no study was designed to compare the dds before and after dietary consultation a...

objective: maternal type and amounts of dietary fatty acids affect on reproductive process in the mice. the present study investigated the effects of maternal supplementation with different amounts of omega-6 or omega-9 during pregnancy on the number of offspring, sex-ratio and duration of gestation. materials and methods: eight-week-old female c57bl/6 mice were randomly assigned into four diet...
