the “driving force - pressure - state - impact – response” modeling framework isadopted to consider the formation mechanisms of environmental risks and the requirements ofecological environment protection. moreover, a systematical index system and evaluation model forthe measurement of the coastal ecological security level is put forward in this paper to assess thestate of coastal ecological en...
Methods The study included 43 patients with isolated and combined sTBI and Glasgow Coma Scale on admission 8 or less (age 32.4 ± 10.8 years, men/ women 36/7). Severe brain contusion was diagnosed in all patients. Emergency surgery was required in 20 patients. All patients received decompressive craniotomy with intracranial hematoma or contusion foci removal. Transcranial duplex investigation wa...
OBJECTIVE Recently, a concept of an individually targeted level of cerebral perfusion pressure that aims to restore impaired cerebral vasoreactivity has been advocated after traumatic brain injury. The relationship between cerebral perfusion pressure and pressure reactivity index normally is supposed to have a U-shape with its minimum interpreted as the value of "optimal" cerebral perfusion pre...
In this study lateral differences in tympanic membrane temperature (TMT) were explored as an index of cerebral lateralization. TMT posttask differences were examined for sustained attention to response tasks (SARTs) following the presentation of negative and neutral emotional picture stimuli. Right TMT changed significantly more from baseline TMT than did left TMT after participants performed S...
INTRODUCTION Synchronized low-frequency fluctuations in the resting-state functional MRI (fMRI) signal have been suggested to be associated with functional connectivity in brain networks (1). However, the underlying mechanism of this connectivity is still poorly understood. To better interpret the resting signal, we examined spontaneous fluctuations at the level of cerebral metabolic rate of ox...
OBJECTIVES To use three-dimensional (3D) power Doppler ultrasound to investigate cerebral blood flow perfusion in fetuses with congenital heart disease (CHD). METHODS The vascularization index (VI), flow index (FI) and vascularization flow index (VFI) in the total intracranial volume and the main arterial territories (middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior ...
