Preliminary evaluation of sagittal and transverse plane cross-sectional variations of the trunk during quiet and deep breathing by optical reflective motion analysis in patients with scoliosis.

Trunk movements during quiet and deep breathing in untreated and in operated patients with scoliosis are not well defined. To evaluate sagittal and transverse plane cross-sectional variations of the trunk during quiet and deep breathing by optical reflective motion analysis (ORMA) in children with scoliosis. Twenty-one patients were divided into three groups: normal subjects (A; n = 6), subjects with untreated scoliosis >50° (B; n = 7) and operated patients (C; n = 8).

[Parathyroid hormone inhibits the apoptosis of osteoblast MC-3T3E1 cells through a non-PLC-dependent protein kinase C pathway].

Objective: To investigate the effect of the non-PLC-dependent protein kinase C (PKC) pathway of parathyroid hormone (PTH) on the apoptosis and proliferation of osteoblast MC-3T3E1 cells.

Methods: MC-3T3E1 cells were seeded in 96-well plates at the density of 1.5×10(4) cells/mL and incubated for 3 day.
