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)
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 Among trauma patients who survive to reach hospital, exsanguination is a common cause of death. A widely practicable treatment that reduces blood loss after trauma could prevent thousands of premature deaths each year. The CRASH-2 trial aimed to determine the effect of the early administration of tranexamic acid on death and transfusion(More)
BACKGROUND Tranexamic acid (TXA) has been shown to reduce blood loss in surgical patients and the risk of death in patients with traumatic bleeding, with no apparent increase in vascular occlusive events. These findings raise the possibility that it might also be effective in traumatic brain injury (TBI). OBJECTIVE The Clinical Randomisation of an(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)
Homologous transfusion has been known to cause viral infections and other complications. Recently, autologous transfusion has been adopted widely as a safer and more effective procedure to prevent these complications. The authors report the experiences of 29 patients who had been operated on after preparation of autologous blood. Furthermore, the authors(More)
Electrophysiological studies were performed in eight patients (four men and four women, mean (SD) age 24 (5) years with paroxysmal attacks of palpitation during or immediately after exercise. Five patients were competitive athletes at college. In two patients spontaneous supraventricular tachycardia during exercise was recorded by ambulatory(More)
