OBJECTIVE This study investigates associations between cortical thickness and pain duration, and central sensitization as markers of pain progression in painful knee osteoarthritis. METHODS Whole brain cortical thickness and pressure pain thresholds were assessed in 70 participants; 40 patients with chronic painful knee osteoarthritis (age = 66.1± 8.5 years, 21 females, mean duration of pain ...
Objectives Due to the small thickness of cortical gray matter in the brain, biological interpretation of image values in the cortical regions on FDG PET images is confounded by tissue atrophy and partial volume effects, especially in patients with Alzheimer Disease (AD). In this study, we developed a method that employs a well established MRI-based cortical brain surface mapping technique to ac...
Background: Old laying hens are more prone to dietary calcium (Ca) and phosphorus (P) deficiencies as they absorb Ca and P less efficiently than younger hens. OBJECTIVES: In a 2×2 factorial design, the influence of diets with two levels of available phosphorus (AP) and phytase enzyme on the laying performance, egg quality and tibia bone characteristics of laying hens at their late 2nd producti...
IMPORTANCE Cannabis use during adolescence is known to increase the risk for schizophrenia in men. Sex differences in the dynamics of brain maturation during adolescence may be of particular importance with regard to vulnerability of the male brain to cannabis exposure. OBJECTIVE To evaluate whether the association between cannabis use and cortical maturation in adolescents is moderated by a ...
The anatomy of cerebral cortex is characterized by two genetically independent variables, cortical thickness and cortical surface area, that jointly determine cortical volume. It remains unclear how cortical anatomy might influence neural response properties and whether such influences would have behavioral consequences. Here, we report that thickness and surface area of human early visual cort...
OBJECTIVE Brain atrophy is common in subcortical ischemic vascular disease, but the underlying mechanisms are poorly understood. We set out to examine the effects of incident subcortical infarcts on cortical morphology. METHODS A total of 276 subjects with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, an inherited small vessel disease, were enroll...
