Background and aims Internet addiction (IA) was recently defined as a disorder tagging both the impulse control and the reward systems. Specifically, inhibitory deficits and reward bias were considered highly relevant in IA. This research aims to examine the electrophysiological correlates and autonomic activity [skin conductance response (SCR) and heart rate] in two groups of young subjects (N = 25), with high or low IA profile [tested by the Internet Addiction Test (IAT)], with specific reference to gambling behavior...

Phthalate esters (PAEs) are man-made compounds that are used widely in industry, and the ubiquitous exposure of humans to PAEs has been reported. Although some PAEs have been suggested to function as xenoestrogens in in vitro systems, such as human estrogen receptors (ERs) expressed in Chinese hamster ovary (CHO)-K1 cells, few studies have attempted to elucidate whether PAEs affect human ERα/ERβ-mediated signaling in human breast cancer cells (i.e., combination between human ERs and human cells). Thus, further experiments are needed in order to clarify the activities of PAEs...

Depression is a disease of an abnormal brain energy metabolism also marked with increased apoptosis in specific brain regions. Mounting evidence indicates that the mitochondrial oxidative phosphorylation and apoptosis are novel targets for the actions of estrogen receptors (ERs). In this study, we examined the effects of antidepressant (AD) fluoxetine (FLU) treatment on the mitochondrial ER alpha (ERα), ER beta (total and phospo-pERβ) and their association with cytochrome c (cyt c) oxidase activity and apoptotic Bcl2/Bax-molecules in the hippocampal mitochondria of chronically isolated (CPSI) female and male rats depicting depression...

Endoplasmic reticulum stress (ERS)-induced intracellular calcium (Ca(2+)) overload and ROS burst plays a critical role in apoptosis. Protein kinase C epsilon (PKCε) is involved in regulating the homeostasis of Ca(2+) and ROS production. isorhamnetin (Iso), as an ROS scavenger, effectively inhibit apoptosis, but the mechanism is still unclear. This study was to investigate whether Iso can inhibit ERS-induced apoptosis in N2a cells, and the protective effects are involved in PKCε-mediated Ca(2+) homeostasis and inhibition of ROS...

The EEG rhythmic activities of the somato-sensory cortex reveal event-related desynchronization (ERD) or event-related synchronization (ERS) in beta band (14-30 Hz) as subjects perform certain tasks or react to specific stimuli. Data reported for imagination of movement support the hypothesis that activation of one sensorimotor area (SMA) can be accompanied by deactivation of the other. In order to improve our understanding of beta ERD/ERS generation, two neural mass models (NMM) of a cortical column taken from Wendling et al...

The present research explored rewarding bias and attentional deficits in Internet addiction (IA) based on the IAT (Internet Addiction Test) construct, during an attentional inhibitory task (Go/NoGo task). Event-related Potentials (ERPs) effects (Feedback Related Negativity (FRN) and P300) were monitored in concomitance with Behavioral Activation System (BAS) modulation. High-IAT young participants showed specific responses to IA-related cues (videos representing online gambling and videogames) in terms of cognitive performance (decreased Response Times, RTs; and Error Rates, ERs) and ERPs modulation (decreased FRN and increased P300)...

Hormonal changes due to menopause can cause various health problems including weight gain and depressive symptoms. Multiple lines of evidence indicate that oestrogen receptors (ERs) play a major role in postmenopausal obesity and depression. However, little is known regarding the ER subtype-specific effects on obesity and depressive symptoms. To delineate potential effects of ERβ activation in postmenopausal women, we investigated the effects of a novel oestrogen receptor β-selective ligand (C-1) in ovariectomized mice...

Hyperoxic acute lung injury (HALI) is a major clinical problem for patients undergoing supplemental oxygen therapy. Currently in clinical settings there exist no effective means of prevention or treatment methods. Our previous study found that: hydrogen could reduce HALI, as well as oxidative stress. This research will further explore the mechanism underlying the protective effect of hydrogen on oxygen toxicity. Rats were randomly assigned into three experimental groups and be exposed in oxygen chamber for 60 continuous hours:100% balanced air (control);100% oxygen (HALI);100% oxygen with hydrogen treatment (HALI+HRS)...

Endoplasmic reticulum stress (ERs) has been regarded as an important cause for the pathogenesis of non-small-cell lung cancer (NSCLC). β-elemene is an active component in the essential oil extracted from a medicinal herb, Curcuma wenyujin, and has been reported to be effective against non-small-cell lung cancer (NSCLC). However, the potential effect and underlying mechanisms of β-elemene on regulating ERs to inhibit NSCLC are still unclear. In the present study, A549 cells and Lewis tumor-bearing C57BL/6J mice were established to evaluate this effect...

OBJECTIVES: American Thoracic Society/European Respiratory Society (ATS/ERS) spirometry interpretation guidelines recommend ≥15 min between pre- and post-bronchodilator testing to evaluate for a bronchodilator response. We aimed to lengthen the time between albuterol administration and post-bronchodilator testing to adhere to ATS/ERS guidelines and evaluated if lengthening this wait time would increase the percentage of patients classified as bronchodilator responsive. METHODS: We compared the proportion of patients with a positive bronchodilator response between two groups of children with asthma, one group in which post-bronchodilator administration wait times were not standardized (pre-intervention) to another in which the wait time was extended to 15 min to adhere to ATS/ERS standards (post-intervention)...

BACKGROUND: Estrogen receptors (ER) α and β are found in both women and men in many tissues, where they have different functions, including having roles in cell proliferation and differentiation of the reproductive tract. In addition to estradiol (E2), a natural hormone, numerous compounds are able to bind ERs and modulate their activities. Among these compounds, phytoestrogens such as isoflavones, which are found in plants, are promising therapeutics for several pathologies. Glyceollins are second metabolites of isoflavones that are mainly produced in soybean in response to an elicitor...

Home mechanical ventilation is increasingly used by people with chronic respiratory failure. However, there are few reports on attitudes towards treatment. A web-based survey in eight languages was disseminated across 11 European countries to evaluate the perception of home mechanical ventilation provision in ventilator-assisted individuals and caregivers. Out of 787 responders from 11 European countries, 687 were patients and 100 were caregivers. 95% of patients and 94% of caregivers were from only 4 countries (Germany, the Netherlands, Italy, Spain)...
