STEP™ Instruments (100 mm Working Length)
Description:...kaged in various configurations and combinations. They are used in conjunction with the Step™ Insufflation and Access needle and the Step™ radially Expandable Sleeve. The 5, 7/8, 10 and 12 mm cannula include a reducer cap which allows the insertion of instruments smaller than the cannula diameter....STEP™ and STEP™ Short Reducers

Description:...e benefits of a ring graft without the rings. Employing a patented, unibody construction, the GORE-TEX INTERING Vascular Graft is the lowest profile, radially supported graft available today. The graft has a smooth, luminal surface that's soft to the touch, and yet is exceptionally strong. It resists kinking...GORE-TEX® INTERING Vascular Graft-Standard Walled

How did bilaterally symmetric flowers evolve from radially symmetric ones? To address this important question, geneticists Francisco Perfectti and Juan Pedro M. Camacho, and ecologist José M. Gómez (Universidad de Granada, Spain) explored how different flower shapes affected plant fitness in natura...New MRI technique could mean fewer breast biopsies in high-risk women

With the team's powerful technique, an MRI machine acquires data radially and generates a high-resolution, three-dimensional image that radiologists can turn, slice and view from many perspectives enabling them to study a l...New method separates cancer cells from normal cells
...these channels leading to a central reservoir, like spokes on a wheel, worked just as well separating cancer and non-cancerous cells. A stack of these radially arranged ratchet channels could be used to create a "cancer trap."

From that zone, crawling neurons migrate radially out toward the surface or "superficial" part of the developing cortex, giving rise to a laminar structure.
