In the 12 years from 1975 to 1987, 55 patients had open pulmonary valve surgery for isolated congenital stenosis of the pulmonary valve. Three types of pulmonary stenosis were seen: (a) dome-shaped pulmonary stenosis (34 patients); (b) dysplastic pulmonary valves with thick cauliflower-like cusps (12 patients), and (c) hour-glass deformity of the pulmonary valve, with "bottle-shaped" sinuses (n...

Bacteriophage T4 consists of a head for protecting its genome and a sheathed tail for inserting its genome into a host. The tail terminates with a multiprotein baseplate that changes its conformation from a "high-energy" dome-shaped to a "low-energy" star-shaped structure during infection. Although these two structures represent different minima in the total energy landscape of the baseplate as...

Molluscum contagiosum (MC) is an infection of the skin and mucous membrane caused by a DNA virus from the poxvirus family. It usually affects any part of the body and presents as pearly, flesh colored dome shaped nodule with a central umbilication. Clinical diagnosis can be supplemented with histopathology for the confirmed diagnosis of MC. This article presents a case of 12-year-old male child...

Volume 82, Number 5 www.aafp.org/afp American Family Physician 517 A 15-year-old boy presented with papules concentrated on his bilateral forearms, elbows, knees, and trunk that arose suddenly five weeks earlier. The patient reported that the lesions became pruritic after showering. He had no personal or family history of similar lesions and took no regular medications. He was obese and had a f...

We describe a method for controllably generating giant balloon-like liposomes through electroformation of densely micro-patterned lipid films. These balloon-like liposomes are still tethered to the substrate through a thin lipid tube. We found that the patterns that were more densely spaced generated the balloon-like liposomes, whereas patterns that were sparsely spaced generated hemi-spherical...

This study was designed to investigate whether there is a difference in the strength of the bony patella following preparation either with a dome configuration or with a regular uniplanar cut in total knee arthroplasty. For each test 4 cadaveric patellae were used. Two of the 4 patellae were prepared with a regular uniplanar cut and 2 were prepared into a dome shape with a circumferential wall,...
