Notching up vascular regeneration

Notching up neural stem cell homogeneity in homeostasis and disease

Adult neural stem cells (NSCs) are perceived as a homogeneous population of cells that divide infrequently and are capable of multi-lineage differentiation. However, recent data revealed that independent stem cell lineages act in parallel to maintain neurogenesis and provide a cellular source for tissue repair. In addition, even within the same lineage, the stem and progenitor cells are strikin...

Cricket: notching up runs for food and alcohol companies?

OBJECTIVE To analyse sports sponsorship by food and alcohol companies by quantifying the proportion of time that the main sponsor's logo was seen during each of three cricket telecasts, the extent of paid advertising during the telecast and the contribution by the main sponsor to this, and to describe the associated ground advertising. METHODS DVD recordings of the three telecasts were analys...

Vitamin D promotes vascular regeneration.

BACKGROUND Vitamin D deficiency in humans is frequent and has been associated with inflammation. The role of the active hormone 1,25-dihydroxycholecalciferol (1,25-dihydroxy-vitamin D3; 1,25-VitD3) in the cardiovascular system is controversial. High doses induce vascular calcification; vitamin D3 deficiency, however, has been linked to cardiovascular disease because the hormone has anti-inflamm...

Regeneration: New Neurons Wire Up

Functional repair of damage in the nervous system requires re-establishment of precise patterns of synaptic connectivity. A new study shows that after selective ablation, zebrafish retinal neurons regenerate and reconstruct some, although not all, of their stereotypic wiring.
