Cardiovascular diseases occur with increasing frequency in our society. Their diagnosis often requires tailored visualization techniques, e.g., to examine the blood flow channel in case of luminal narrowing. Curved Planar Reformation (CPR) addresses this field by creating longitudinal sections along the centerline of blood vessels. With the possibility to rotate around an axis, the entire vesse...

Summary Although advances in coating technologies have allowed us to match—or even exceed—the lubricity of Nature's low-friction surfaces, the performance synthetic materials inevitably diminishes over time as surfaces are worn and damaged by irreversible breakage covalent bonds. Synthetic systems lack bespoke repair mechanisms that replenish hydration lubrication Nature. Here, we demo...

Acute photo-inactivation of clathrin in Drosophila synapses sheds new light on a 35-year-old debate over mechanisms of synaptic-vesicle endocytosis: clathrin is essential for reformation of functional synaptic vesicles, but not for bulk membrane internalization.

Everyone makes mistakes. Still, getting things wrong can be a lonely experience. In religious thought as in philosophy or cognitive science, error is equated with imperfection: anyone who wants to be right needs to correct or supersede mistakes. Indeed, certainty—the need to be sure one is right—has been identified as the obsession that defined the age in Susan Schreiner’s powerful recent study...

Traditional techniques for visualizing anatomical structures are based on planar sections from volume images, like images obtained by computed tomography (CT) or magnetic resonance imaging (MRI). However, planar slices taken in the coordinate system of the 3D image often do not provide sufficient or qualitative enough diagnostic information. The reason is that because planar slices do not follo...

Received March 5, 1984; accepted May 18, 1984. On physical examination, there was tenderness in the L 1 area. Neurologic examination was normal. Initial radiographs (fig. 1A) of the lumbosacral spine revealed a compression fracture of the L 1 vertebra; subsequent myelography demonstrated an extradural block at the same level. At surgery, a standard posterior exposure of the dorsal arches of T10...

The excision repair process following ultraviolet irradiation has been fractionated into its individual steps in toluene-treated cells. Incision can be examined in vitro independently of other reactions by omission of the deoxyribonucleoside triphosphates which prohibits repair synthesis and causes incisions to accumulate. Incision requires ATP, continues from 10 to 15 min at 37”, and is specif...

Potorous tridactylis (PTK2) cells growing in culture were treated with psoralen derivatives and dividing cells were located by phase-contrast microscopy. Psoralens, light-sensitive DNA-photoadducting drugs, were reacted with mitotic chromosomes through exposure to 365-nm light from an argon laser microbeam system. It was found that following mitosis and photoreaction, cells without nuclear enve...
