Individuals who have sustained a traumatic brain injury (TBI) often exhibit an array of cognitive deficits, yet perhaps most maladaptive of these sequelae is the frequent occurrence of reduced insight into one's own condition. In such cases, TBI individuals may overestimate their post-injury level of socio-cognitive functioning, leading to disparities(More)
BACKGROUND Dietary vitamin K is usually inadequate to maximize serum osteocalcin gamma-carboxylation. Phylloquinone supplementation increases osteocalcin gamma-carboxylation; however, the amount required to maximize carboxylation is not known. OBJECTIVE This study assessed the ability of various doses of phylloquinone (vitamin K(1)) to facilitate(More)
Neuroimaging research has demonstrated that the posterior cingulate cortex (PCC) is functionally compromised in individuals diagnosed with amnestic mild cognitive impairment (MCI), a major risk factor for the development of Alzheimer's disease (AD). In functional MRI studies with healthy participants, this same region is active during self-appraisal(More)
Limited data in humans and animals indicate that excess vitamin A stimulates bone resorption and inhibits bone formation, effects that over time might lead to bone loss and fracture. Thus, it is possible that vitamin A supplementation is a currently unrecognized risk factor for the development of osteoporosis. To further evaluate this possibility, a(More)
Although the number of new cases of basal cell carcinoma (BCC) has increased rapidly in the last few decades, the molecular basis of its pathogenesis is not completely understood. Activation of the Hedgehog (Hh) signaling pathway has been shown to be a key factor driving the development of BCC. The Wnt/β-catenin signaling pathway was also shown to be(More)
BACKGROUND Psychocutaneous medicine studies the boundaries between skin and mind, and takes the unique approach of examining the patients in their biopsychosocial context. It can help patients with chronic skin problems cope with anxiety and the social stigma of their disease. Decreased psychologic stress can contribute to better treatment outcomes and be(More)
To the Editor , We are writing in response to the innovative articles published by Mooney et al. and Brick et al. about employing virtual dermatopathology (DP) for clinical use and pathology education.1,2 Because the diagnostic equivalence between virtual and conventional microscopy has been supported by comparative studies, virtual DP has been implemented(More)
