An investigation was carried out to evaluate the growth performance of six commercial broiler hybridsavailable in Iran (Arbor Acres, Arian, Cobb 500, Hubbard, Lohmann and Ross 508). Two hundred and fiftyfertile eggs of each hybrid were taken from different breeder farms, all over the country. The similarity offlocks ages and their health conditions were considered. After hatching, the sexed chi...

The discovery of either a dermatomal cutaneous nevus or a spinal arteriovenous malformation (AVM) should raise the suspicion of Cobb syndrome. The Cobb syndrome is a neurocutaneous syndrome in which there are metameric cutaneous and spinal AVMs. The authors present the case of a patient with acute cervical myelopathy and subtle cutaneous hemangiomas in whom a cervical perimedullary fistula was ...

Method Study Design: Retrospective study. Population. 388 (31 males) patients respecting these inclusion criteria: AIS diagnosis, Risser test 0-3; all Cobb degrees; no prior treatment; who had reached the end of treatment since our institute database start in 2003. Methods: Clinical and radiographic (Cobb degrees) data at the beginning of treatment have been compared to end growth results. Trea...

Methods This is a cohort of 43 patients (all female) with AIS who underwent posterior spine fusion. The patients were divided into two group which were thoracic curve group (n=30, Lenke 1, 2, 3, 4) with a mean age of 14.6 years and a mean Cobb angle of 54° and lumbar/thoraco-lumbar group (n=14, Lenke 5, 6) with a mean age of 14.6 years and a mean Cobb angle of 56° Each was compared for preopera...

Materials and methods Case-control study in with 85 patients with AIS and 25 healthy volunteers. AIS patients were classified into two groups determined by the curve mangitude): A (Cobb angle 25-40°) and B (Cobb angle >40°). Main outcomes were: respiratory muscle strength estimated by maximal inspiratory and expiratory preassures (MIP, MEP), peripherical muscle strength assessed in hands and lo...

STUDY DESIGN A retrospective study. OBJECTIVE The aim of this study was to detect risk factors for Adding-on after posterior correction surgery in patients with Lenke 1 or 2 AIS, and to explore whether Adding-on Index could be used to predict Adding-on effectively. SUMMARY OF BACKGROUND DATA Adding-on phenomenon is a common complication in Lenke 1 or 2 AIS patients after correction surgery....

Standard growth theory implies that steady-state growth in the presence of exponential declines in the prices of computers and other capital equipment requires a Cobb-Douglas production function. Conventional wisdom holds that capital shares are relatively constant, so that the Cobb-Douglas approach might be a good way to model growth. Unfortunately, this conventional wisdom is misguided. Capit...
