BACKGROUND The prefrontal cortex (PFC) is a heterogeneous cortical structure that supports higher cognitive functions, including working memory and verbal abilities. The PFC is vulnerable to neurodegeneration with healthy aging and Alzheimer disease (AD). OBJECTIVE We used volumetric magnetic resonance imaging to determine whether any region within the PFC is more vulnerable to deterioration ...

METHODS A series of 40 dissections were performed on 20 preserved or fresh male cadavers. The site origin and drainage of vessels, caliber, length, and correlation between diameter and length of pedicle were identified. RESULTS The SIEA and SIEV were identified at in...

The local dynamic stability of trunk movements was assessed during repetitive lifting using nonlinear Lyapunov analyses. The goal was to assess how varying the load-in-hands affects the neuromuscular control of lumbar spinal stability. Thirty healthy participants (15M, 15F) performed repetitive lifting at 10 cycles per minute for three minutes under two load conditions: zero load and 10% of eac...

background: oral lichen planus is a chronic inflammatory disease with a poorly understood etiology. the role of angiogenesis in the development of different chronic inflammatory diseases is of great concern. vascular endothelial growth factor (vegf) is an important regulator of angiogenesis. we aimed to evaluate the serum level of vegf in patients with oral lichen planus compared with normal in...

BACKGROUND The pyridinium cross-links pyridinoline (PYD) and deoxypyridinoline (DPD) are established markers of bone resorption. We evaluated the analytical and clinical performance of a commercially available PYD HPLC assay and established reference intervals in children and adults. METHODS We used a commercially available reagent set (Chromsystems Instruments & Chemicals) to measure PYD and...
