Disruption of Resting-State Functional Connectivity in Acute Ischemic Stroke: Comparisons Between Right and Left Hemispheric Insults.

Few resting-state functional magnetic resonance imaging (RS-fMRI) studies evaluated the impact of acute ischemic changes on cerebral functional connectivity (FC) and its relationship with functional outcomes after acute ischemic stroke (AIS), considering the side of lesions. To characterize alterations of FC of patients with AIS by analyzing 12 large-scale brain networks (NWs) with RS-fMRI. Additionally, we evaluated the impact of the side (right (RH) or left (LH) hemisphere) of insult on the disruption of brain NWs.

Real-Time Monitoring of Neurocritical Patients with Diffuse Optical Spectroscopies.

Neurophysiological monitoring is an important goal in the treatment of neurocritical patients, as it may prevent secondary damage and directly impact morbidity and mortality rates. However, there is currently a lack of suitable non-invasive, real-time technologies for continuous monitoring of cerebral physiology at the bedside. Diffuse optical techniques have been proposed as a potential tool for bedside measurements of cerebral blood flow and cerebral oxygenation in case of neurocritical patients.

Real-Time Non-invasive Assessment of Cerebral Hemodynamics With Diffuse Optical Spectroscopies in a Neuro Intensive Care Unit: An Observational Case Study.

Prevention of secondary damage is an important goal in the treatment of severe neurological conditions, such as major head trauma or stroke. However, there is currently a lack of non-invasive methods for monitoring cerebral physiology. Diffuse optical methods have been proposed as an inexpensive, non-invasive bedside monitor capable of providing neurophysiology information in neurocritical patients.

Normal cerebral cortical thickness in first-degree relatives of temporal lobe epilepsy patients.

Objective: To examine cerebral cortex thickness in asymptomatic first-degree relatives of patients with mesial temporal lobe epilepsy (MTLE).

Methods: We investigated 127 asymptomatic first-degree relatives of patients with MTLE due to hippocampal sclerosis (HS) (mean age ± SD = 39.4 ± 13 years) and 203 healthy control individuals (mean age ± SD = 36.

Psychological stress and its influence on salivary flow rate, total protein concentration and IgA, IgG and IgM titers.

Unlabelled: The hypothalamic-pituitary-adrenal and sympathetic-adrenomedullary axes are the main systems activated in response to stress. Alterations in salivary components and flow rate have been associated with oral health problems and psychological stress.

Objectives: The aim of the present study was to investigate the influence of psychological stress on salivary flow, total protein concentration and IgG, IgM and IgA concentrations.

Cell phenotyping in saliva of individuals under psychological stress.

Total leukocytes, NK cells, B and T lymphocytes present in the saliva of medical students with or without stress were quantified by flow cytometry in 10,000 events. The symptoms of psychological stress were monitored with Lipp's Inventory of Stress Symptoms for Adults (ISSL). No significant differences were observed in the number of cells phenotyped in students with and those without psychological stress.
