“…The pulse wave attenuation was measured under different ranges of ophthalmodynamometric force (ODF) as a function of distance along the vessel (V(Dist)), which in turn was calculated in disc diameters (DD) from the center of the optic disc. A linear mixed-effects model with randomized slopes and intercepts was used to estimate the correlations between the logarithmically transformed harmonic regression wave amplitude (HRW(a)) and the Fourier trigonometric coefficients with the predictors (V(Dist) and ODF). …”

“…He was admitted to the in-patient department and a brain MRI was performed, which revealed intense infra and supratentorial leptomeningeal enhancement, with involvement of the hypothalamus and optic chiasm. Laboratory evaluation revealed significantly reduced gonadotrophin and testosterone levels (FSH 1.1U/L, LH 0.43U/L, total testosterone 4.5ng/dL), normal prolactin and no other HP hormonal deficits. …”

“…Six fresh frozen human thoracic spine specimens with intact rib cages (C7-L1) were loaded with pure moments of 5 Nm in flexion/extension, lateral bending, and axial rotation, while monitoring the relative motions of all spinal segments using optical motion tracking. The specimens were tested (1) in the intact condition, followed by testing after vertebral body replacement at T6 level using a unilateral approach combined with (2) long instrumentation (T4–T8) and (3) short instrumentation (T5–T7) as well as a bilateral approach combined with (4) long and (5) short instrumentation. …”
