results the mean age of patients was 16.7 ± 2.5 years. there was no statistically significant difference between the two groups regarding gender, age, curve before surgery, and percentage of flexibility. the mean curvature was 70 ± 20.7 in the hr and 64.81 ± 19.4 in the cd group before surgery (p = 0.09); and the mean curvature was 40 ± 16.3 and 26.58 ± 15.37 in hr and cd groups respectively af...

With the development of the Harrington rod (Harrington, 1962) a long-segment rod and hook instrumentation was available for the first time, which became the worldwide standard procedure for many years in the surgical treatment of adolescent idiopathic scoliosis. According to a retrospective meta-analysis, Harrington rods were used in more than 85% of such cases between 1958 and 1993 (Haher et a...

Stanford scientists have developed a fluorescence imaging technique that allows them to view the pulsing blood vessels of living animals with unprecedented clarity. compared with conventional imaging techniques, the increase in sharpness is akin to wiping fog off your glasses. the technique, called near infrared-2 imaging, or nir-2, involves first injecting water-soluble carbon nanotubes into t...

 Abstract Objective: To present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the Harrington rod (HR) and posterior multisegmented hook instrumentation. Methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with Harrington technique (106 patients) or multise...

It is shown that there exists a low2 Harrington non-splitting base — that is, a low2 computably enumerable (c.e.) degree a such that for any c.e. degrees x,y, if 0′ = x ∨ y, then either 0′ = x ∨ a or 0′ = y ∨ a. Contrary to prior expectations, the standard Harrington non-splitting construction is incompatible with the low2-ness requirements to be satisfied, and the proof given involves new tech...

Psychotic illnesses (schizophrenia and schizoaffective and affective psychosis) have a lifetime prevalence of 2–3% and probably occur at a similar rate in all human societies. No etiologically significant environmental precipitants have been identified, and this suggests that these diseases are primarily genetic. Brain studies reveal that in schizophrenic patients, development of cerebral asymm...
