UCLA cancer researchers shake loose hidden biomarker

...hin the cell. We found that if we disturbed hollow tubular structures called microtubules, part of the cell's framework, we were able to relocate PSMA from its 'hidden' location on the apical membrane to an accessible area in the basolateral surface." To cause this disturbance and the resulting relocation o...

Virginia Tech, Nanjing Institute researchers discover half-billion year-old fossils

...hus replicating the three-dimensional shape of the tubular structures. How did these Ediacara organisms live? "We think that the fossils were preserved where they lived. In other words, they had not been transported a long way from their deathbed to their graveyard." Zhou said, "And the way they occur in th...

Stem cells bring fast direct improvement, without differentiation, in acute renal failure

...neys, such "insults" lead to destruction of kidney tubular and vascular cells, initiating a significant inflammatory response. Recovery of kidney function that is adequate for patient survival depends primarily on the protection and regeneration of destroyed and injured cells. Yet virtually no progress has ...

University of Delaware researchers develop cancer 'nanobomb'

...n nanotubes, which are atoms of carbon arranged in tubular form. Originally, he said, the research team was looking at the use of the carbon nanotubes as drug delivery vehicles. Because they are smaller than the size of a single cell, the nanotubes can provide for the highly selective injection of drugs i...

University of Pittsburgh School of Medicine researchers develop 'off-the-shelf' vascular grafts

... or spraying, MDSCs inside a biodegradable porous, tubular polyester urethane scaffold using a rotational vacuum seeding device. After culturing their vascular constructs for seven days, the investigators then implanted them in the abdominal aortas of rats eight weeks before performing tests to determine...
