fourth rib methods. The current study tests Hartnett’s revised methods as well as the original Suchey-Brooks and Iscan etal. methods on a modern sample from the William Bass Skeletal Collection (N=313, mean age=58.5, range 19-92). Results show that the Suchey-Brooks and Iscan etal. methods assign individuals

to the correct phase 70.8% and 57.5% of the time compared with Hartnett’s revised methods at 58.1% and 29.7%, respectively, with correctness scores based on one standard deviation of 3-Methyladenine supplier the mean rather than the entire age range. Accuracy and bias scores are significantly improved for Hartnett’s revised pubic symphysis method and marginally better for Hartnett’s revised fourth rib method, suggesting that the revised mean ages at death of Hartnett’s phases better reflect this modern Napabucasin population. Overall, both Hartnett’s revised methods are reliable age estimation methods. For the pubic symphysis, there are significant improvements in accuracy and bias scores, especially for older individuals; however, for the fourth rib, the results are comparable to the original Iscan etal. methods, with some improvement for older individuals.”
“Directing spatial attention to a location inside the classical receptive field (cRF) of a neuron in macaque medial temporal area (MT) shifts the center of the cRF toward the attended location. Here

we investigate the influence of spatial attention on the profile of the inhibitory surround present in many MT neurons. Two monkeys attended to the fixation point or to 1 of 2 random dot patterns (RDPs) placed inside or next to the cRF, whereas a third RDP (the probe) was briefly presented in quick succession across the

cRF and surround. The probe presentation responses were used to compute a map of the excitatory receptive field and its inhibitory surround. Attention systematically reshapes the receptive ZD1839 nmr field profile, independently shifting both center and surround toward the attended location. Furthermore, cRF size is changed as a function of relative distance to the attentional focus: attention inside the cRF shrinks it, whereas directing attention next to the cRF expands it. In addition, we find systematic changes in surround inhibition and cRF amplitude. This nonmultiplicative push-pull modulation of the receptive field’s center-surround structure optimizes processing at and near the attentional focus to strengthen the representation of the attended stimulus while reducing influences from distractors.”
“Background & Aims: IL-17 secreting CD4 (Th17) and CD8 (Tc17) T cells have been implicated in immune-mediated liver diseases, but the molecular basis for their recruitment and positioning within the liver is unknown.\n\nMethods: The phenotype and migratory behaviour of human liver-derived Th17 and Tc17 cells were investigated by flow cytometry and chemotaxis and flow-based adhesion assays. The recruitment of murine Th17 cells to the liver was studied in vivo using intra-vital microscopy.
