Since the publication of the Bellcore measurements in the early nineties, long-range dependence (LRD) has been in the center of a continuous debate within the teletraac community. While researchers largely acknowledge the signiicance of the LRD phenomenon, they still disagree on two issues: (1) the utility of LRD models in buuer dimensioning and bandwidth allocation, and (2) the ability of comm...

BACKGROUND In insulin-resistance, VLDL presents alterations that increase its atherogenic potential. The mechanism by which insulin-resistance promotes the production of altered VLDL is still not completely understood. The aim of this study was to evaluate the relationship between the expression of sterol regulatory element binding protein 1c (SREBP-1c) and of peroxisome proliferator-activated ...

We have constructed a questionnaire to investigate the separation behavior in a sample of family dogs (Canis familiaris) (N = 45) and in parallel we have observed dogs’ separationrelated behavior in a simple behavioral test (Separation and greeting test, S&G). We recorded the dogs’ behavior during the separation from and reunion (greeting) with the owner. We investigated whether owners’ report ...

Recent experiments with reading disabled children have shown that image blurring (produced with frosted acetate overlays) results in an immediate benefit in search performance, eye movement pattern and reading comprehension. This suggests that the contrast and spatial frequency content of visual stimuli are important factors for these children. In the present experiment, spatial frequency filte...

OBJECTIVE The purpose of this retrospective study is to determine the fetal lung-to-liver signal intensity ratio (LLSIR) on T2-weighted images for the prediction of neonatal respiratory outcome. METHODS One hundred ten fetuses who underwent magnetic resonance imaging (MRI) examination for various indications after 22 weeks of gestation participated in this study. LLSIR was measured as the rat...

A meta-analysis was conducted to investigate whether specific reading disorder (SRD) groups demonstrate a deficit in using phonological recoding strategies. Thirty-four studies were reviewed that had compared the nonword reading performances of SRD groups with reading-level matched (RL) control groups. The average nonword reading difference between groups across the total number of studies was ...

We compared the efficacy of intravitreal aflibercept (IVA) to intravitreal ranibizumab (IVR) injections in eyes with diabetic macular edema (DME). The medical records of 49 eyes of 36 patients who were diagnosed with DME and had received IVR and 46 eyes of 40 patients who had received IVA treatment were reviewed. The central macular thickness (CMT) and best-corrected visual acuity (BCVA) were m...

Administration of a sucrose-rich diet (SRD) to normal hamsters induces an insulin-resistant state and a significant increase of insulin secretion and beta-cell mass. Islets isolated from these animals had a marked increase in glucose metabolism and glucose-induced insulin secretion, at both low and high glucose concentrations. They also presented increased hexokinase (HK) activity, without meas...

OBJECTIVE To evaluate the test-retest reliability of isometric and isokinetic muscle strength measurements in the upper extremity after stroke. DESIGN A test-retest design. SUBJECTS Forty-five persons with mild to moderate paresis in the upper extremity > 6 months post-stroke. METHODS Isometric arm strength (shoulder abduction, elbow flexion), isokinetic arm strength (elbow extension/flex...

BACKGROUND REM sleep has antiepileptogenic properties whereas, its loss is known to have a proconvulsive role. However, the mechanisms underlying the proepileptogenic effects of REM sleep deprivation are yet not fully understood. The aim of our study was to evaluate the effects of selective REM sleep deprivation (SRD) on cortical excitability in healthy subjects by means of transcranial magneti...
