It concludes with some reflective comments on the author’s Archaeological Theory: An Introduction, in advance of the third revised edition.
Ready-to-eat (RTE) food is characterised by a long shelf-life at refrigerated temperature and can be consumed as such, without any treatment. The aim of the work was to evaluate the presence of Listeria spp. and Listeria monocytogenes in RTEs collected from refrigerated vending machines placed in hospital environment and accessible to the hospitalised patients. In 4 different sampling, 55 RTEs ...
The population of naive T cells in the periphery is best described by determining both its T cell receptor diversity, or number of clonotypes, and the sizes of its clonal subsets. In this paper, we make use of a previously introduced mathematical model of naive T cell homeostasis, to study the fate and potential of naive T cell clonotypes in the periphery. This is achieved by the introduction o...
T lymphopoiesis in the thymus was thought to be completed once they reach the single positive (SP) stage, when they are "fully mature" and wait to be exported at random or follow a "first in-first out" manner. Recently, accumulating evidence has revealed that newly generated SP thymocytes undergo further maturation in the thymic medulla before they follow a tightly regulated emigrating process ...
Phylogenetic relationships between the known genera of the order Misophrioida permit the identi® cation of two lineages: one consisting of the family Misophriidae Brady, 1878 which comprises seven genera, and a new, monotypic family, the Palpophriidae Boxshall & Jaume, 1999; the other consisting of another new family, the SpeleophriidaeBoxshall & Jaume, 1999, comprising eight genera. Habitat ex...
conclusions our results suggest that human exposure to mcpyv occurs throughout life. the mcpyv antibody levels remained high among older adults in our population, consistent with reports from other populations. patients and methods in this cross-sectional study, we collected 440 serum samples from healthy individuals 2 to 78 years of age who visited the pasteur institute’s clinic in tehran, ira...
images of the two simultaneously excited slices. Displayed are (a) the conventional reconstruction of the CAIPIRINHA acquisition using GRAPPA and (b) the reconstruction of the incoherently undersampled CAIPIRINHA acquisition using the proposed combination of Compressed Sensing and GRAPPA. (c) Difference between a) and b) magnified by a factor of 10. Accelerated Simultaneous Multi-slice Cardiac ...
