Comparative Study of Novel Noninvasive Cerebral Autoregulation Volumetric Reactivity Indices Reflected by Ultrasonic Speed and Attenuation as Dynamic Measurements in the Human Brain.

This is a comparative study of two novel noninvasive cerebrovascular autoregulation (CA) monitoring methods based on intracranial blood volume (IBV) changes in the human brain. We investigated the clinical applicability of the new volumetric reactivity index (VRx2), reflected by intracranial ultrasonic attenuation dynamics for noninvasive CA monitoring. The CA was determined noninvasively on 43 healthy participants by calculating the volumetric reactivity index (VRx1 from time-of-flight of ultrasound, VRx2 from attenuation of ultrasound).

Acute and chronic effects of soccer game on the retinal vessel diameters in middle-aged adults.

Background: Although changes in retinal vessel diameter is a new biomarker for the evaluation of cardiovascular risk factors, limited information is available regarding the effects of endurance exercises on retinal microcirculation. Thus, we aimed to evaluate both chronic and acute effects of soccer game on the diameters of retinal vessels in middle-aged players.

Methods: Retinal vessel diameters were measured in 12 middle-aged amateur players (44.

Effects of core stability exercises on multifidus muscles in healthy women and women with chronic low-back pain.

Background: Chronic low-back pain (LBP) may be related to decreased lumbar multifidus muscle cross-sectional area (CSA).

Objective: In this study, core stabilization exercises were designed to enhance neuromuscular control and correct multifidus dysfunction.

Methods: The subjects were healthy women (n = 11) and women with chronic LBP (n = 17).

Test-Retest Cross-Reliability of Tests to Assess Neuromuscular Function as a Multidimensional Concept.

The purpose of this investigation was to estimate the test-retest cross-reliability of peripheral and central changes with respect to nonlinear and linear measures of a surface electromyography (EMG) signal measured during isometric maximal voluntary contraction (MVC) combined with superimposed electrical stimulation during a brief and fatiguing task involving the ankle plantar flexors over 2 follicular phases of menstrual cycle. Ten healthy female adults underwent 1 familiarization session and 5 identical test-retest sessions. The results showed that the decrease in plantar flexor EMG components (root mean square [RMS], mean frequency [MnF], wavelet packet entropy [WPE]) for soleus and gastrocnemius muscles, central activation ratio (CAR) and MVC, and contractile properties (P20, P100, PTT-100, and half-relaxation time) of the plantar flexor muscles at the end of 2-minute MVC were similar (time effect; p < 0.

Coats' retinitis or retinoblastoma in a 3-year-old girl: a case report.

Coats' disease is an idiopathic disorder defined by an abnormal development of retinal vessels with a progressive deposition of intraretinal or subretinal exudates, leading to exudative retinal detachment. The most difficult task is to differentiate Coats' disease from retinoblastoma. We present a rare case of Coats' disease diagnosed in a 3-year-old girl.

Ultrasonic measurement of ocular rectus muscle thickness in patients with Graves' ophthalmopathy.

Unlabelled: The aim of this study was to evaluate changes in extraocular muscle thickness and to assess its correlation with the degree of proptosis in patients with Graves' ophthalmopathy (GO).

Material And Methods: A total of 242 patients (207 females and 35 males) with Graves' ophthalmopathy were enrolled into the study (GO group). Their mean age was 53.

Investigations of ocular changes, extraocular muscle thickness, and eye movements in Graves' ophthalmopathy.

Unlabelled: The aim of this study was to evaluate ocular changes, to measure the thickness of extraocular muscles, and to assess eye movements in patients with active Graves' ophthalmopathy.

Material And Methods: We examined 27 patients (18 women and 9 men) with Graves' ophthalmopathy. Their age ranged from 17 to 59 years; mean age was 42.
