Poised to migrate

Hearts grow with the flow properly formed heart comes only after effort—the pumping of cells through a primitive heart to generate gene-activating shear forces. who have come up with a method for watching heart development by culturing developing zebrafish on microscope stages. The researchers tracked the movement of blood cells against the background of fluorescently stained blood serum. High-...

Protein kinase C: poised to signal.

Nestled at the tip of a branch of the kinome, protein kinase C (PKC) family members are poised to transduce signals emanating from the cell surface. Cell membranes provide the platform for PKC function, supporting the maturation of PKC through phosphorylation, its allosteric activation by binding specific lipids, and, ultimately, promoting the downregulation of the enzyme. These regulatory mech...

The Willingness to Migrate in the CEECs .

Mast cells migrate from blood to brain.

It is well established that mast cells (MCs) occur within the CNS of many species. Furthermore, their numbers can increase rapidly in adults in response to altered physiological conditions. In this study we found that early postpartum rats had significantly more mast cells in the thalamus than virgin controls. Evidence from semithin sections from these females suggested that mast cells were tra...

Extracting Prior Knowledge from Data Distribution to Migrate from Blind to Semi-Supervised Clustering

Although many studies have been conducted to improve the clustering efficiency, most of the state-of-art schemes suffer from the lack of robustness and stability. This paper is aimed at proposing an efficient approach to elicit prior knowledge in terms of must-link and cannot-link from the estimated distribution of raw data in order to convert a blind clustering problem into a semi-supervised o...
