Elliptic Fourier analysis of crown shapes in Quercus petraea trees [PDF]
Shape is a fundamental morphological descriptor, significant in taxonomic research as well as in ecomorphology, one method of estimation being from digitally processed images. In the present study, were analysed shapes of Q. petraea crowns, pertaining to

Is there a true match in the femoral medullary cavity between neutral and flexion alignment of the stem on a female (Asian) population? [PDF]
Background In total hip arthroplasty, stem alignment has been proposed to occur in the neutral and flexed positions. Nonetheless, there is a paucity of research on the relationship between the shape of the medullary cavity cross-section and its ...

Development of Douglas fir merchantable stem volume model in the conditions of the Czech Republic
A precise merchantable stem volume model of Douglas fir [Pseudotsuga menziesii (Mirb.) Franco] is missing in the Czech Republic. The aim of this study was to fit a new model through the reparametrization of volume equations (used in the Czech Republic or

Inflammation Shapes Stem Cells and Stemness during Infection and Beyond [PDF]
The outcome of an inflammatory incident can hang in the balance between restoring health and tissue integrity on the one hand, and promoting aberrant tissue homeostasis and adverse outcomes on the other. Both microbial-related and sterile inflammation is a complex response characterized by a range of innate immune cell types, which produce and respond ...

Epigenetic Regulation Shapes the Stem Cells State [PDF]
Pluripotent stem cells are endowed with the dual capacity to self-renew and to differentiate towards all lineages. Genetic and genome-wide studies in different model organisms have provided compelling evidence for the importance of epigenetic factors both in the maintenance of pluripotency and in the establishment of cell lineage commitment, during ...

Epithelial Stem Cells: Making, Shaping and Breaking the Niche [PDF]
AbstractEpithelial stem cells maintain tissues throughout adult life and are tightly regulated by their microenvironmental niche to balance cell production and loss. These stem cells have been studied extensively as signal-receiving cells, responding to cues from other cell types and mechanical stimuli that comprise the niche.

Keeping the Epidermal Stem Cell Niche in Shape [PDF]
Recently in Nature Cell Biology,Connelly et al. (2010) identified biomechanical sensing mechanisms that link the physical shape of the stem cell microenvironment to epithelial stem cell fate decisions. Ultimately, the integration of extrinsic and intrinsic signals controls stem cell self-renewal or differentiation.

Intrinsic Immunity Shapes Viral Resistance of Stem Cells [PDF]
Stem cells are highly resistant to viral infection compared to their differentiated progeny; however, the mechanism is mysterious. Here, we analyzed gene expression in mammalian stem cells and cells at various stages of differentiation. We find that, conserved across species, stem cells express a subset of genes previously classified as interferon (IFN)

Effects of Stem Density on Crown Architecture of Scots Pine Trees
Trees adapt to their growing conditions by regulating the sizes of their parts and their relationships. For example, removal or death of adjacent trees increases the growing space and the amount of light received by the remaining trees enabling their ...
