National Environmental Quality Standards (EQS) for zinc used for the assessment of ecological status in freshwaters have been shown to vary by over two orders of magnitude across 25 European countries. Such variability is unlikely to reflect consistent ecological protection or environmental relevance. Recent European technical guidance on EQS derivation gives an opportunity to derive protective metrics for zinc that are relevant to national water chemistry conditions. To derive a zinc EQS relevant to national water chemistry conditions and account for bioavailability, the new technical guidance requires high-quality spatial and temporal monitoring data. These data must be of water samples with concurrent measures of pH, dissolved organic carbon (DOC) and calcium, the parameters that most influence zinc bioavailability in freshwaters. A national bioavailability-based zinc EQS for France has been derived from Biotic Ligand Model calculations undertaken for freshwaters samples from 4645 sites (22,000 samples with concurrent measures of pH, DOC, calcium) in 96 regions. An EQS of 11.3 μg Zn L-1 was derived based on sensitive waters from the Bretagne region typically of circumneutral pH and relatively low DOC and low dissolved calcium. The least sensitive waters to zinc exposures in France are found in the Hauts-De-France, higher pH values than those in Bretagne, similar dissolved organic carbon and higher dissolved calcium. An indicative assessment of compliance showed that across France, 2% of the sites would exceed this bioavailability-based EQS.Bilateral ovariectomy is the best characterized and the most reported animal model of human menopause. Ovariectomized rodents develop insulin resistance (IR) and visceral obesity, the main risk factors in the pathophysiology of metabolic syndrome (MS). These alterations are a consequence of hypoestrogenic status, which produces an augment of visceral fat, high testosterone levels (hyperandrogenism), as well as inflammation, oxidative stress, and metabolic complications, such as dyslipidemia, hepatic steatosis, and endothelial dysfunction, among others. Clinical trials have reported that menopause per se increases the severity and incidence of MS, and causes the highest mortality due to cardiovascular disease in women. Despite all the evidence, there are no reports that clarify the influence of estrogenic deficiency as a cause of MS. In this review, we provide evidence that ovariectomized rodents can be used as a menopausal metabolic syndrome model for evaluating and discovering new, safe, and effective therapeutic approaches in the treatment of cardiometabolic complications associated to MS during menopause.The study of the complex impact of the cognitive and psychological factors' interplay in learning process has for long obsessed educational researchers. In an attempt to partially address the issue, the present study investigates the direct and indirect interrelationship among Iranian EFL learners' basic psychological needs satisfaction, goal-orientation, willingness to communicate, learning strategy use, self-efficacy and second language achievement through a path analytic research design. To this end, 506 Iranian undergraduate English students took the related questionnaires and based on the collected data, a hypothesized model of interrelationship among variables was tested using AMOS statistical package. According to the final path analytic tested model, L2 achievement was predicted by goal orientation, self-efficacy, and learning strategy use. Moreover, while basic psychological needs satisfaction did not directly predict L2 achievement, it was indirectly associated with L2 achievement through goal orientation. The findings imply that the teachers need to first identify the most relevant individual sources of performance variation in their context and next design procedures to maximally cope with inhibitive psychological or cognitive factors which associate with their learners' rate and route of learning. Moreover, language learners need to be more oriented towards setting their future goals, believing in their capabilities, and use more learning strategies.To compare a novel Compressed SENSE accelerated ECG- and respiratory-triggered flow-independent 3D isotropic Relaxation-Enhanced Angiography without Contrast and Triggering (modified REACT) with standard non-ECG-triggered 3D contrast-enhanced magnetic resonance angiography (CE-MRA) for imaging of the thoracic aorta in patients with connective tissue diseases (CTD) or other aortic diseases using manual and semiautomatic measurement approaches. This retrospective, single-center analysis of 30 patients (June-December 2018) was conducted by two radiologists, who independently measured aortic diameters on modified REACT and CE-MRA using manual (Multiplanar-Reconstruction) and semiautomatic (Advanced Vessel Analysis) measurement tools on seven levels (inner edge) Aortic annulus and sinus, sinotubular junction, mid- and high-ascending aorta, aortic isthmus, and descending aorta. Bland-Altman analysis was conducted to evaluate differences between the mean values of aortic width and ICCs were calculated to assess inteificance was found between both measurement techniques (p = 0.08). Fosbretabulin purchase As a novel non-CE-MRA technique, modified REACT allows for fast imaging of the thoracic aorta with higher image quality in the proximal aorta than CE-MRA enabling a reliable measurement of vessel dimensions without the need for contrast agent. Thus, it represents a clinically suitable alternative for patients requiring repetitive imaging. Manual and semiautomatic measurement approaches provided comparable results without significant difference in time need.

Critical illness has detrimental effects on the diaphragm, but the impact of critical illness on other major muscles of the respiratory pump has been largely neglected. This study aimed to determine the impact of critical illness on the most important muscles of the respiratory muscle pump, especially on the expiratory muscles in children during mechanical ventilation. In addition, the correlation between changes in thickness of the expiratory muscles and the diaphragm was assessed.

This longitudinal observational cohort study performed at a tertiary pediatric intensive care unit included 34 mechanical ventilated children (> 1month- < 18years). Thickness of the diaphragm and expiratory muscles (obliquus interna, obliquus externa, transversus abdominis and rectus abdominis) was assessed daily using ultrasound. Contractile activity was estimated from muscle thickening fraction during the respiratory cycle.

Over the first 4days, both diaphragm and expiratory muscles thickness decreased (> 10%) in 44% of the children.
