A new model of stretch-induced growth is evaluated in four chicken wing muscles stretched to different extents by a spring-loaded tubular assembly. Muscles grew in length and cross section in proportion to the extent to which they were stretched. Longitudinal growth was essentially completed within 1 wk, while muscles grew in cross section through at least(More)
Skeletal muscle growth induced by passive stretch was characterized in chicken wing muscles. Within 24 h after installing the stretch apparatus on the birds, the sarcomere length of the stretched patagialis was 40% greater than control. This was accompanied by increasing muscle wet weight, protein content, DNA and RNA concentrations. Sarcomere length(More)
BACKGROUND This article addresses the use of liquid injectable silicone as both an immediate and long-lasting treatment for broad-based, depressed acne scars. The only filler substance that maintains precision and permanence in improving and/or correcting these types of acne scar defects is medical-grade liquid silicone. OBJECTIVE We describe five(More)
This article discusses the use of medical-grade liquid silicone injections for perioral rejuvenation and lip augmentation and treating various scars and defects in these areas. Recommended concepts and techniques for optimum results are also highlighted based on 40 years' experience with liquid silicone injections. The benefits of combining silicone(More)
Growth of chicken patagialis muscle in response to passive stretch for 7 days was studied in the absence and presence of the DNA synthesis inhibitor hydroxyurea. In the absence of hydroxyurea, the DNA content and concentration of the stretched muscle increased 101% and 40%, respectively, relative to the unstretched contralateral control. Stretch-induced(More)
We tested the influence of PGE2 on protein degradation in isolated mouse and rat muscles. PGE2 had no influence on protein degradation rate in mouse muscles under several different incubation conditions and over a dose range of 28 nM to 28 microM. Furthermore, neither PGE2 (2.8 microM) nor arachidonic acid (5 microM) influenced protein degradation in rat(More)
Rhinoplasty entails several steps that affect the appearance and function of the nose in an interrelated way. Occasionally, an excellent result can be marred by a minor imperfection and lead to dissatisfaction of both patient and surgeon. For significant pathology, revision rhinoplasty can be performed safely if the architecture and physiology of the nose(More)
Vero cytotoxin-producing Escherichia coli O157 (VTEC O157) infections are a threat to public health. VTEC O157 has been isolated from gulls but evidence of transmission to humans from birds has not been reported. We recount an incident of VTEC O157 infection affecting two sibling children who had no direct contact with farm animals. An outbreak control team(More)
A 78-year-old man with a 2-year history of a large dermatitis-like plaque of his thigh is described. It had a raised elevated border, resembling persistent fungal dermatitis (tinea corporis). However, it proved to be a squamous cell carcinoma, prompting this description and a reminder that skin cancer may mimic dermatitis.
