br Results br Discussion In view


In view of their potential use in cell-based therapy for patients with PD, midbrain DA neurons were one of the first cell types to be generated from iPSCs. The resemblance between iPSC-derived DA neurons and true DA neurons has been studied based on a number of mainly morphological and functional properties, as well as mdDA-specific gene sets (Hedlund et al., 2008; Kriks et al., 2011; Wernig et al., 2008). However, the risk of tumor growth and the heterogeneous molecular backgrounds of embryonic stem cell (ESC)- and iPSC-derived DA neurons have precluded the use of these prostaglandin receptor for therapy in humans (Momčilović et al., 2014; Salti et al., 2013). Gaining a detailed understanding of the genetic and epigenetic signatures of ESC- and iPSC-derived DA neurons is therefore a critical step toward establishing cell-based therapy as a viable treatment for PD. In this study, we present a comparative genome-wide profile of the genetic and epigenetic features of iPSC-derived DA neurons and their primary counterparts. Although iPSC-derived DA neurons showed characteristics that are widely used to classify functional mdDA neurons (Ganat et al., 2012; Kriks et al., 2011; Sundberg et al., 2013), caused a reduction in rotation behavior in a rat model for PD, and adopted many of the genetic and epigenetic features of their primary counterparts, we also observed major deviations that may interfere with proper functionality after grafting.
Since DA neurons obtained via induced pluripotency undergo defined developmental stages in vitro, we compared them with primary embryonic and postnatal mdDA neurons. To generate iPSCs and differentiate them into DA neurons, we applied a combination of currently widely accepted and standardized protocols (Chambers et al., 2009; Kawasaki et al., 2000; Takahashi and Yamanaka, 2006). We made use of transgenic Pitx3 mice (Maxwell et al., 2005) to isolate primary mdDA neurons and reprogram embryonic fibroblasts into iPSCs, which were subsequently differentiated into DA neurons. The transcription factor PITX3 has been demonstrated to be one of the most stringent markers for fully differentiated, functional mdDA neurons (Smidt et al., 2003, 2004), and expression of the PITX3-GFP reporter allowed us to strictly identify and FACS purify iPSC-derived and primary mdDA neurons.
Although transcript analysis indicated that proviral gene expression introduced during reprogramming was silenced in iPSC-derived mdDA neurons, we still found residual expression of fibroblast markers. It was previously shown that iPSCs are prone to differentiate along their somatic parental lineages because they maintain a parental epigenetic memory (Bar-Nur et al., 2011; Kim et al., 2010; Sullivan et al., 2010). Although some studies suggested that such epigenetic memory is restricted to early-passage iPSCs (Polo et al., 2010), others reported that parental epigenetic states also persist in late-passage iPSCs (Kim et al., 2011). This could explain why we observed fibroblast marker expression and a permissive DNA methylation state for some of the fibroblast genes in PITX3-GFP-positive cells derived from high-passage (p15–p20) iPSCs.
To determine whether the epigenetic states of the analyzed neuron populations reflected similarities and differences in gene-expression profiles, we analyzed global DNA methylation patterns in primary embryonic mdDA neurons (E14.5) and iPSC-derived DA neurons. In contrast to the case with undifferentiated iPSCs, we found strong general de novo methylation in iPSC-derived DA neurons. Earlier studies reported that PSCs mostly contain methylation-free promoters, as well as methylation-free intergenic and orphan CGIs (Illingworth et al., 2010). De novo methylation was only found upon loss of pluripotency, suggesting that transcriptional repression in PSCs is established predominantly via other mechanisms (Fouse et al., 2008; Mohn et al., 2008). Indeed, we observed that most de novo methylation events occurred during differentiation from pluripotent cells to multipotent precursors isolated from an iPSC-derived NESTIN-GFP reporter line (data not shown).

In this study we have

In this study, we have developed a three-step protocol to differentiate hESCs to endothelial progenitor l-ascorbic acid cost (EPCs) using human recombinant laminins that are biologically relevant (LN521, LN511, and LN421) to mimic the in vivo endothelial substrata. First, vascular cell lineages emerge from mesoderm during embryogenesis (Huber et al., 2004). The next phase directs these mesoderm-committed cells toward the endothelial lineage (CD34+vascular endothelial growth factor receptor [VEGFR2]+CD31+VE-Cadherin+) (Sahara et al., 2014). At the last stage, to obtain a pure population of ECs, a CD31+ population is purified using CD31-coupled magnetic beads. With this three-step protocol, we were able to obtain a 95% CD34+VEGFR2+CD31+VE-Cadherin+ population after 15 days. Using RNA-sequencing (RNA-seq) technology, we compared transcriptomes of our hESC-derived EPCs with that of human umbilical vein endothelial cells (HUVECs), which are fully mature and the most commonly used human primary ECs. The results confirmed expression of markers in the early endothelial lineage, as well as the presence of some mature markers. In short, our differentiation protocol allows efficient generation of pure EPCs in a chemically defined and xeno-free system, which can be applicable for therapeutic purposes as well as modeling human diseases.


Our laboratory has produced multiple laminin isoforms as recombinant proteins, and developed chemically defined and xeno-free hESC derivation and culture systems using biologically relevant substrata LN511 or LN521. Both of these laminins, which are developmentally regulated, are also present in other BMs that, additionally, may contain other tissue-specific laminin isoforms (Domogatskaya et al., 2012; Miner et al., 1998). The results of this study demonstrate the possibility to produce high-quality, homogeneous cultures of EPCs from pluripotent hESCs that are cultured on these two laminins found in all subendothelial BM. Our hESC-derived cells were functionally demonstrated by tube formation and DiIAcLDL uptake assays, and expressed specific markers for the endothelial lineage and vasculogenesis.
Global transcriptome analysis shed light on the expression of genes involved in cell-cell and cell-matrix interactions, as well as expression signatures during differentiation toward maturity of the endothelial cell lineage (Figure 6). The data revealed that pluripotent hESCs do not produce high amounts of BM components, emphasizing the importance of providing the initial relevant supporting matrix, such as LN521, for hESCs to survive and maintain their pluripotency (Rodin et al., 2014a). hESCs, EPCs, and mature HUVECs did not produce Fibronectin (FN1), Fibulin-1 (FBLN1), Fibrillin-1 (FBN1), or Vitronectin (VTN), suggesting that these proteins are not biologically relevant coating substrata when culturing these cells in vitro. Interestingly, the subendothelium-specific laminin α4 chain did not appear until cells became fully mature. Along the endothelial lineage, our EPCs expressed collagen type IV as the main structural BM component, which is likely to provide structural support, while laminin α5 chain expression was low, possibly because it was added exogenously. When we allowed our cells to mature further after purification, important endothelial-specific BM markers, such as von Willebrand factor, laminin α4 chain, and matrix metallopeptidase MMP1 had an increase in mRNA levels over the 6-week period, reaching levels similar to those of HUVECs. Our results suggested that a switch in ECM composition might occur alongside a faster turnover as the cells progress toward maturation. For example, Perlecan was the main BM component expressed in HUVECs, indicating that this proteoglycan bearing a high affinity for growth factors is needed for EC proliferation during vascular development (Zoeller et al., 2009). Both laminin α4 chain and matrix metallopeptidases MMP1, MMP2, and MMP14 were highly expressed, suggesting that the main laminins LN411 and LN421 in the HUVEC BM undergo a constant turnover.

Similar results regarding film uniformity were obtained for all other

Similar results regarding film uniformity were obtained for all other samples. Table 3 lists the data allowing to compare the calculated stoichiometric composition of elements with the averaged experimental results. The analysis of the data in Table 3 leads us to conclude that the CuTPP and ZnTPP samples exhibit an approximate agreement of the elemental contents in thin films with the calculated values. The copper content in the CuTPP sample turns out to be insignificantly (by about 1wt%) lower, and the zinc content in ZnTPP higher, compared with the calculated values. Substantially larger deviations have been observed in the content of nitrogen impurities, observed to be increased in comparison with stoichiometry only prostaglandin receptor for CuTPP films. This may be associated with different content of the air adsorbed in the films, which substantially depends on the structure of the film and, respectively, on the surface area of the condensate. We are going to demonstrate below that a more developed surface is typical for CuTPP films, and, as a consequence, they can absorb a significantly larger amount of air. Differences in the structure and surface morphology of films of different tetraphenylporphyrins will be discussed further.
Component analysis of thin film samples of the coordinated FeClTPP complex revealed two features distinguishing it from copper and zinc metalloporphyrins. Firstly, thin films of the complex are significantly (by about three times) chlorine-depleted. Secondly, a substantial amount of oxygen (up to 7wt%) is found in these films, which is much greater than the contents of adsorbed oxygen in copper and zinc tetraphenylporphyrin films. Quantum chemical calculations performed for the complex with FeCl showed that the Cl prostaglandin receptor is weakly bound to the rest of the structure (the Mayer bond order of Fe–Cl in a coordinated complex has a value of 0.2). Ref. [9] established, for the MnIIICl porphyrin similar in structure, that a complete loss of chlorine atoms coordinated to the metal occurred for an adsorbed [SAc]P-MnIIICl monolayer on Ag(100) under heating up to 498K; however, there was no loss of metal atoms and no destruction of macrocycles. Thus, during the sublimation process and at temperatures of about 600K, atoms can partially break away from the metalloporphyrin, with the free radicals formed capable of effectively interacting with the residual oxygen and, potentially, with hydroxyl groups, establishing sufficiently strong chemical bonds. Fig. 2 shows possible scenarios of chlorine substitution by oxygen, the formation of complex structures with μ-bridged complexes [8] and of iron oxychloride, hydroxyl. However, all of these scenarios could explain an increase in the oxygen content in the films up to a maximum of 2.3% even in case of complete substitution of chlorine by oxygen complexes. The excess oxygen content cannot be associated with the air adsorbed on the surface, as it is not accompanied by a corresponding increase in its content in nitrogen films. However, a study of EPR spectra of cobalt porphyrins [10] noted that it is possible for CoIITPP to form a bond with an O2 molecular ligand coordinated to the metal atom. A similar presence of bound molecular oxygen in our samples could explain such high values of the oxygen content in FeClTPP films. Thus, accurate determination of the chemical structure of the films obtained by evaporation of the FeClTPP complex requires further study. It should be noted that the magnetic characteristics of these films would also substantially depend on the method by which they were fabricated.

Surface morphology of metalloporphyrin films
Surface morphology of 500nm-thick films prepared from the ZnTPP mixture (Fig. 3a) was investigated by electron microscopy, which revealed that the films have a smooth surface and are composed of large columnar crystals up to 2µm in length, closely packed and forming a thick film. It can be seen on the defect (cleavage) of the film that the crystallization is characterized by an elongated crystal axis and occurs mainly parallel to the substrate.

Finally gestation and early infancy are critical

Finally, MG 149 and early infancy are critical periods for health and overweight development in adolescence and adulthood (Currie & Almond, 2011; Dietz, 1994). To explore this association we ran models controlling for median income and mean education in the municipality at the time when each individual was born. We did not have information corresponding about occupational status at birth. In females, inclusion of income at birth reduced the variance in overweight with 27%, which was almost identical to the reduction observed when income in 2012 was added. Inclusion of education at birth reduced the variance in overweight in females with 32%, compared with 34% when education in 2012 was added. In men, the corresponding numbers were 26% at birth and 21% in 2012, 29% for education at birth and 32% for education MG 149 at in 2012. Finally, we ran models including all SES variables at the time of birth and in 2012. In females, 59% of the variance was explained, compared with 57% in the models including SES in 2012 only. In men, the comparable numbers were 41% and 40%, respectively.

The association between individual body mass index and area-level socio-economic resources supports findings reported in previous studies. A number of these studies have used composite indicators of SES (Adams et al., 2009; Chen & Truong, 2012; Do et al., 2007; Feng & Wilson, 2015; Sundquist, Malmström, & Johansson, 1999; Wen & Maloney, 2014), while other studies have looked specifically at area-level income (Cetateanu & Jones, 2014; King et al., 2006), area-level education (Harrington & Elliott, 2009) or area-level occupational status (Cetateanu & Jones, 2014). A Canadian study, which included school-aged children, used individual-level SES variables in addition to area-level income, occupation and education. This study found that both individual- and area-level SES variables were negatively associated with individual BMI (Janssen, Boyce, Simpson, & Pickett, 2006). However, the mentioned studies explore the associations between high BMI and area-level SES; they do not estimate how much of the geographic variation in high BMI that could be explained by SES. To our awareness, our study provides the first estimates of this.
The study was based on an extensive register data source, which provided information on height and weight among women and men in 428 Norwegian municipalities. However, there are limitations that need to be taken into consideration when interpreting the findings. First, our measure of overweight was based on BMI, which has been criticized because telophase does not incorporate measures of body fat, which is an independent predictor of ill health (Burkhauser & Cawley, 2008). Second, and related to this, there may be measurement errors: if BMI is mis-measured (as it was based on self-reported height and weight), and if the level of mis-measurement is associated with SES, our coefficients might be biased. Finally, there may be reverse causality and omitted variables, either at the individual- or area-level, and the implications of this are discussed in more detail below.

Recent literature suggests the importance of cross-border ties on health and well-being (Acevedo-Garcia, Sanchez-Vaznaugh, Viruell-Fuentes, & Almeida, 2012), and that there is growing recognition that migrants are affected by both cultures at the destination and ties to sending communities (Olwig, 2006). Cross-border ties have been defined as the process of maintaining relationships across borders through various means (Mouw, Chavez, Edelblute, & Verdery, 2014). The impact of cross-border ties and health is mixed, suggesting that it may have both protective and adverse health effects for migrants (Torres, 2013). It can provide a type of social protection across borders that may have an effect on the health behaviors of migrants (Faist, Bilecen, Barglowski, & Sienkiewicz, 2015), including how healthcare services are accessed, where migrants seek health-related advice, and how they obtain medication (Heyman, Nunez, & Talavera, 2009; Menjivar, 2006; Wang & Kwak, 2015). One study of Korean immigrants to Canada found that migrants often return to their hometowns for health examinations, import their medications, and seek advice from people back home by phone or online platforms (Wang & Kwak, 2015). Therefore, ties to hometowns take on many forms with potentially wide-ranging consequences and effects.

Madecassic acid manufacturer While previous studies have analyzed trust from an

While previous studies have analyzed trust from an organizational perspective, as well as the role that the leader plays in the creation of a trusting environment, there is currently no consistent theoretical and empirical body of knowledge regarding the study of trust in the leader in virtual settings and the variables that influence it (Zhang & Fjermestad, 2006). Thus, previous literature has not proposed a model that allows the factors that influence the building of trust in a virtual team leader to be accurately understood. This study seeks to reduce this shortcoming in the literature by analyzing some of those factors that may influence trust in a virtual leader.
This paper proposes two types of antecedent factors of trust in the leader of a virtual team: the physical attributes of the leader (degree of attractiveness) and the behavioral attributes of the leader (degree of empathy and justice). On the other hand, it should be noted that some of the relationships between the antecedent factors and trust may be moderated by other aspects, such as leadership style. With regards to this, theory points to two basic styles of leadership: leaders with a transformational style (Pillai, Schriesheim, & Williams, 1999), and leaders with a transactional style.

Literature review and the formulation of hypotheses

The data collection process and the validation of the measurement scales

To Madecassic acid manufacturer the proposed hypotheses, the structural equations model shown in Fig. 1 was developed.
The fit of the model presented acceptable values (Bentler–Bonett Non-normed Fit Index=0.897; Comparative Fit Index (CFI)=0.920; Bollen (IFI) Fit Index=0.921; Root Mean Sq. Error of App. (RMSEA)=0.092; 90% RMSEA Confidence Interval (0.082, 0.110)).
Focusing on the antecedents of trust in a virtual leader, we observe that physical attractiveness has a positive and significant effect on trust in a leader (β=0.077; p<0.05). Therefore the hypothesis H1 is accepted. Likewise, behavioral traits of a virtual leader such as empathy (β=0.362; p<0.01) and perceived justice (β=0.413; p<0.01) exert a positive and significant effect on trust, therefore hypotheses H2 and H4 are also accepted. Furthermore, the results reveal the existence of a positive and significant relationship between the degree of perceived attractiveness and the perceived empathy of a leader (β=0.486; p<0.01), allowing us to also accept hypothesis H3.
In order to test the moderating effect of leadership style, a multi-sample analysis was performed. For each of the analyses, the total sample of individuals was divided into two groups. To form the groups, the mean of the corresponding item was taken in each case, and a series of cases around this value (±½standard deviation) were eliminated. Secondly, an LM-Test analysis, “Lagrange Multiplier Test” (Engle, 1984) was performed in order to check if differences existed among the parameters obtained for the two groups and if these differences were significant.
Hypothesis H5 argues that for well-defined leadership styles, i.e. highly transformational or highly transactional styles of leadership, the leader\’s attractiveness will have less influence on trust. The analysis of the results reveals that the relationship between the degree of attractiveness and trust in the leader is moderated in the case where the leader employs a more transformational leadership style (p<0.01). In fact, the presence of a negative parameter (β=−0.031; p<0.01) for the attractiveness→trust relationship for the more transformational sample suggests that the effect is not only weaker, but indicates that the influence of attractiveness on trust diminishes for very transformational leadership styles (see Table 5). However, there is no statistically significant moderating effect when the leader exerts a very transactional leadership style (β=−0.003, p=0.217). Therefore, hypothesis H5 should be rejected.

Satisfaction with CSR initiatives therefore

Satisfaction with CSR initiatives therefore becomes a key metric of the successful development and implementation of a CSR policy. Consumers may wish to reward companies with good CSR records positively or even with non-negative information in the form of resilience to negative information about the company (Bhattacharya & Sen, 2004). Recent literature has not only delineated how to achieve this relationship between CSR initiatives and positive attitudes, but also how to offer to business practitioners a comprehensive framework for identifying appropriate responses to consumer demands, based on three different motivations: instrumental, relational and moral (Caruana & Chatzidakis, 2014). However, the relationship between CSR initiatives and customer satisfaction has been scarcely researched and consequently, our understanding of the disaggregated drivers and causes may be incomplete. We also argue that positive attitudes may be expected to trigger satisfaction and hence CSR must have a positive influence on satisfaction.
Thus, our aim in this research is twofold: first, to assess what kinds of CSR initiatives significantly influence consumer satisfaction with the company; second, to assess the mediating role exerted by brand attitude in the relationship between CSR and satisfaction. These two main research objectives are accomplished through two different studies in two different countries, USA and Spain that reflect two cultural settings and also depict different cultural patterns in each of the five current six cultural dimensions suggested by Hofstede and Hofstede (2001).

CSR and consumer satisfaction
Following Beckmann (2007), it can be said that CSR has a wide variety of effects on hsp90 inhibitors that can only be tested in a diffuse rather than a compact way. In fact, consumers react to some CSR initiatives but not others due to their level of knowledge, congruence fit between consumer profile and company products, and brand characteristics (Bigné, Currás, Ruiz, & Sanz, 2012); their reaction also varies in relation to the relationships between corporate skills and CSR initiatives (Du, Bhattacharya, & Sen, 2007; Lichtenstein et al., 2004); and perceived trustworthiness of the information source (Mohr, Webb, & Harris, 2001; Robinson, Irmark, & Jayachandran, 2012). In addition to these consumer-related effects, cultural context, technological, economic, political and social factors have been shown to influence CSR assessments (Dahlsrud, 2008). Although the literature is abundant in terms of CSR and its effects, there are still gaps in the understanding of other variables that may assess the performance of a brand in adopting CSR initiatives. Brand loyalty has been suggested as a recurring theme in the CSR literature showing that higher levels of CSR associations are linked to stronger loyalty behavior because consumers develop a more positive, stronger evaluation of the firm (Brown & Dacin, 1997; Sen & Bhattacharya, 2001). Recent studies have focused on novel effects of CSR, like brand equity (Torres, Bijmolt, Tribó, & Verhoef, 2012) or behavioral effect, such as repeat patronage intentions (Auger, Devinney, Louviere, & Burke, 2010; Vlachos, Tsamakos, Vrechopoulos, & Avramidis, 2009).
In this paper we attempt to argue the role of satisfaction as a key metric in evaluating CSR performance. In the marketing domain, satisfaction has been used typically as a measure of overall performance of a brand. Furthermore, it has proven its relevance for non-marketing effects, such as stock prices (Anderson, Fornell, & Mazvancheryl, 2004; Fornell et al., 2006), employee satisfaction (Frey et al., 2013) and consumer spending growth (Fornell et al., 2010). Given the broader nature of CSR for firms, satisfaction might explain the adequacy in monitoring company performance. Satisfaction is considered to be a judgment that is cognitive-affective and relative, that is, the result of comparison between a subjective experience and a previous standard Oliver (1997, p.13) that may be used to evaluate companies’ CSR initiatives. Customer satisfaction, based on customer relations with the brand and its CSR initiatives can be approached from the perspective of overall or specific issues. In this study we examine overall issues because specific issues tend to be related to other constructs such as cause-brand fit (Bigné et al., 2012), brand credibility (Bigné, Chumpitaz, & Currás, 2010) or altruistic attributions (Ellen, Webb, & Mohr, 2006) deriving in context related findings. Although those factors play a role, they might be considered mediators in a specific initiative rather than overall and superior explanatory issues.

The world health organization recognized CVDs as the leading cause

The world health organization recognized CVDs as the leading cause of global mortality, accounting for 46.2% (17.5 million) of deaths caused by non-communicable diseases [20]. Inadequate sleep was associated with increased risk of developing CVDs [21]. Usually, short sleep duration was associated with cardiovascular disease-related mortality and long sleep duration with non-cardiovascular related mortality [22]. Further, short sleep duration was significant risk factor for hypertension [23]. Self-reported hypertension was associated with sleep problems also in Finland [16]. In the present study, CVD risk factors were significantly associated with one or more sleep problems. For example, cardiac insufficiency was significantly associated with increased odds for poor sleep quality. Hypertension was significantly associated with increased odds in seasonal variation in sleep duration. Likewise, AP1903 Supplier pectoris was associated with both seasonal variation and sleep debt. The results are in line with the existing studies, that reports higher morbidity, mortality and hospitalization rates for CVDs [24,25]. According to the evidence, poor sleep quality and short sleep duration (<6h per night) were independent risk factors for type 2 diabetes [18,26,27]. Hormonal changes, due to sleep debt, contribute to insulin resistance, which could, therefore, be a risk factor for diabetes. In a case-control study, 34% of diabetic patients reported sleep-related problems compared to 8% of controls [14]. Many experimental studies indicated that short sleep duration (<7h/night) and poor sleep quality decreased glucose tolerance and reduced insulin sensitivity, which showed the link between diabetes and sleep problem [28–30]. Another study reported that circadian misalignment, which commonly occurs as a consequence of poor sleep, disturbed glucose-insulin metabolism and substrate-oxidation, thereby suggesting further associations between sleep and diabetes [31]. However, in contrary to earlier evidence, the present study showed no significant associations between sleep problems and diabetes. In like manner, sleep problem was also a common complaint of cancer patients [32]. As cited in the review by Roscoe and colleagues [33], many studies have reported a strong correlation between cancer-related fatigue and sleep problems such as poor sleep quality, difficulties of falling asleep, and poor sleep efficiency. Symptoms such as pain, melancholy, loss of concentration as well as a decrease in other cognitive functions clusters in cancer patients [34–36]. In contrary to earlier findings, the present study showed no significant association between sleep parameters and cancer. On the other hand, patients with lung diseases often had poor sleep quality due to abnormalities in breathing during sleep [37]. In a large multi-country survey, the likelihood of sleep problem was significantly higher among older asthmatics (≥50years) than other chronic diseases in Finland [16]. In the present study, the odds for poor sleep quality were increased more than 1.5-fold among those with respiratory disease. In 1989, Hyyppä and Kronholm [38] found an association between somatic diseases and poor quality of sleep among Finnish population. Likewise, acid-related gastrointestinal diseases were important determinants of poor sleep quality among elderly Finns [39]. In line with the available evidence, gallstones and degenerative arthritis in the present study were significantly associated with the increased odds of poor sleep quality. Furthermore, epidemiological and clinical studies have reported a strong correlation between sleep problems and depression [40,41]. In a large community-based population study, short sleep duration, and increased sleep disturbances were independently associated with increased cortisol secretion suggesting chronic stress [42]. In line with the existing evidence, in the present study depression was associated with range of sleep problems including inadequate total sleep and nap duration, seasonal variations in sleep duration, and poor sleep quality. Likewise, other mental disorders were associated with inadequate total sleep and nap duration. To our knowledge, no prior studies have directly assessed the associations of renal failure and proteinuria with sleep-related problems. However, some earlier studies have shown that sleep problems had increased the risk of CVDs, hypertension, diabetes, and obesity, all of which were implicated in the etiology of chronic kidney diseases [43]. More recent studies have indicated sleep problems also among kidney patients [44,45]. In line with the existing evidence, the present study too showed that all of the sleep problems increased the odds of renal failure.

At a later point of time

At a later point of time, when the fastest arriving stimulus used in a previous associative learning event reaches the nervous system, it reactivates the IPL and activates the inter-LINKed postsynaptic terminal from a lateral direction (Fig. 1D). When the postsynaptic terminal is in a background state of continuous depolarization induced by the neurotransmitter molecules released from its presynaptic terminal (Fig. 1A), any “incidental” lateral activation of the postsynaptic terminal through the IPL is expected to induce a semblance of the arrival of activity from its presynaptic terminal as a systems property (see Fig. 1 for further c-kit inhibitor description). Semblance is an expected event of cellular hallucination induced at the inter-LINKed postsynaptic terminal [19,20]. Such an operation is essential for inducing the function of internal sensations; for example, memory [22]. Another integral part of the system property is that the lateral entry of activity through the IPL can contribute to the horizontal component of the oscillating potentials recorded extracellularly [23]. During the wake state, maintaining the extracellularly-recorded oscillating potentials at a certain frequency range is essential for inducing the internal sensations of various higher c-kit inhibitor functions. For example, as the background frequency recorded by the electro-encephalogram (EEG) waves is reduced, there is a gradual reduction in the level of awareness that eventually leads to a state of unconsciousness [24].

We present a case trial of sleep stage detection using a novel electroencephalographic (EEG) recording platform placed in the ear (ear-EEG). In current practice, polysomnography (PSG) during hospitalization is the gold standard for diagnosing sleep disorders. However, PSG is also a relatively resource intensive investigation, which limits its use. Home PSG as a less expensive alternative has been investigated finding unsatisfactory recordings in 13 of 48 patients, the main cause of unsatisfactory recordings being loss of EEG data [1]. We envision that ear-EEG fills this gap.
The ear-EEG devices are customized to each user similar to hearing-aid earplugs. This secures tight contact between the recording electrodes and the skin. Ear-EEG as a method has been tested in awake, healthy subjects using a variety of known EEG paradigms [2]. Compared to scalp EEG it maintains a similar signal-to-noise ratio, being less contaminated by electro-muscular artifacts albeit at a cost to signal amplitudes [3]. Correlation analysis between ear-EEG and scalp-EEG shows the highest degree of similarity for scalp electrodes near the temporal region decreasing towards the midline [4]. Thus one can make reasonable assumptions that sleep related phenomena predominantly found near the midline, such as vertex sharp waves, would be less likely to be resolved with ear-EEG.

The ear-EEG device consists of four recording electrodes embedded in a solid cast made from individually fitted ear impression moulds. We used two ear-EEG devices simultaneously. The recording electrodes are labelled E, I, B and A (Fig. 1).
We recorded simultaneous scalp EEG for comparison. Scalp electrode configuration followed the international 10–20 system with 25 electrodes including inferior temporal chain and EOG. For sleep staging, we used electrode positions F3, C3, O1, F4, C4, O2 contralaterally referenced to M1 and M2 on the mastoid processes as recommended by The American Academy of Sleep Medicine [5]. The study has been approved by the National Board of Health and the Local Ethics Committee.
The validation setup is 3 fold:
The subject was a 30 y.o. male with no known medical problems who participated after giving informed consent. Ear-EEG and simultaneous scalp EEG were recorded for 21h including one night’s sleep. The amplifier used was a Nicolet wireless 64-channel system sampling at 256Hz. Both scalp and ear-EEG electrodes was connected to the same amplifier. For visual inspection of raw data we used proprietary software (Nervus reader v.5.93.424, from Cephalon, Denmark). For frequency analysis of the EEG we calculated power spectrograms in Matlab using the pwelch function. Ear-EEG signals have smaller amplitudes compared to standard EEG. To compensate we displayed scalp signals at 100 µV/cm and ear-EEG signals at 30µV/cm. This preferentially amplified low frequency noise in ear-EEG channels making parts of the EEG difficult to read due to high-amplitude waveforms. To offset this effect we displayed duplicates of ear-EEG channels with different low cut filters, one at 2.0Hz and the other at 0.5Hz. Using the latter is necessary for identification of the slow waves of N3 sleep, but using a low cut at 2.0Hz improved the readability of parts of the EEG where faster frequencies predominated.

contratación con los particulares para la prestación del servicio público de transmisión y distribución de electricidad, conforme reverse transcriptase lo establecido en el Decreto, se extiende a prácticamente todo el ámbito de la actividad, esto es, financiamiento, instalación, mantenimiento, gestión, operación y ampliación de la infraestructura; la excepción es, quizá, la administración y cobro de la venta de electricidad a la multitud de hogares mexicanos que contrata el servicio con la y que sin duda es difícil que puedan constituir un negocio rentable.
Decreto anuncia que en dos años Pemex y se convertirán en Empresas Productivas del Estado; no establece el tratamiento de las actividades que ahora realizan y que fueron eliminadas de las reservadas en exclusiva al Estado (refinación, petroquímica y generación eléctrica, entre otras) o a los términos en que ambas entidades serán liquidadas en su condición actual de organismos públicos desconcentrados; se desconoce por ejemplo cuál será el destino de los pasivos financieros y laborales (es deseable que no se desemboque en otros “fobaproas”) o de los reportes que con fines contables y financieros rinde Pemex a la U. S. Security Exchange Commission, en los cuales las reservas probadas que tiene el encargo de explotar por cuenta de la Nación soportan la aceptación de los títulos que emite y circulan en los mercados internacionales.
Decreto no hace referencia al sistema nacional de precios de los energéticos, se entiende que éstos se liberan al mercado, con lo cual la política de impuestos al consumo, y de eventuales subsidios, debe transparentarse, pero la propaganda de disminución de precios no se sustenta, y mucho menos la conjetura de que se incrementará la extracción de gas natural y con ello bajarán los precios de la electricidad; téngase presente que tal cosa no ha sucedido en las últimas tres décadas en el caso del petróleo y los petrolíferos, a pesar de que la producción del crudo ha sido alrededor del doble del consumo interno y no por ello los precios han disminuido.
señala que para alentar la producción nacional se establecerán “porcentajes” mínimos de participación de la proveeduría nacional; es dudoso, por decir lo menos, que en los términos planteados se alcance el resultado deseado; los tratados internacionales y los acuerdos de libre comercio suscritos por México tienen precisamente la finalidad de evitar prácticas de protección a trace fossil la producción nacional que entorpezcan el libre comercio; además, las empresas petroleras son propietarias o arriendan bienes de capital que utilizan para la exploración y extracción de los hidrocarburos, suponer que el contenido nacional de esos bienes se puede incrementar para lograr la adjudicación en una licitación, no sólo contraría los principios fundamentales de la ansiada competitividad, implica desconocer la operación de esos mercados; la estrategia así planteada es errónea o ilusa.
Decreto reitera términos de sustentabilidad, protección al medio ambiente, cambio climático, energías limpias y energías renovables, pero el propósito de los cambios constitucionales es afianzar los combustibles fósiles en la matriz energética, recuperar el terreno perdido de los hidrocarburos en la oferta nacional de energía y alejarse de las fuentes distintas a las fósiles; las referencias a los vocablos ambientales y a la transición energética son expresiones de generosidad muy atendibles, pero no contienen fundamento legal o institucional alguno que vislumbre alterar la inercia actual. Una vez más se incurre en la práctica habitual de no priorizar la protección del medio ambiente; primero, antes del 20 de abril, se contará con leyes que regularán los cambios constitucionales en materia de energía, e incluso se dispondrá del marco jurídico para crear un órgano autónomo desconcentrado de la Secretaria de Medio Ambiente y Recursos Naturales (), la Agencia Nacional de Seguridad Industrial y de Protección al Medio Ambiente del Sector Hidrocarburos, y después, “sin mayor prisa”, antes del fin de diciembre, como complemento o derivado, a la zaga de las modalidades regulatorias y del nuevo órgano burocrático, se dispondrá de la legislación ambiental.

Ante el anuncio del refer ndum y de

Ante el anuncio del referéndum y de la imposición del corralito se endureció la posición de la ue. El mismo Jean-Claude Juncker no dudó en señalar:
En rigor, GS-1101 lo que Grecia aspiraba era a prorrogar las fechas de vencimiento del préstamo recibido en ocasión del segundo rescate y a fijar nuevas, y mejores, condiciones para un tercer rescate. Para el gobierno de Grecia el monto de la deuda era (es) impagable, pero no solo: el propio Fondo Monetario Internacional había reconocido, tres días antes del referéndum, que la deuda era insostenible y por ello los acreedores europeos de Grecia (que en conjunto absorben 60% de esa deuda –contra 15% en 2011) deberían hacerle caso al Fondo y aceptar que:
La pregunta que se les formulaba a los griegos era muy simple: “¿Debería aceptarse el acuerdo que fue entregado por la Comisión Europea, el Banco Central Europeo y el Fondo Monetario Internacional en el Eurogrupo del 25.06.2015 y que se compone de dos partes y que constiuye su propuesta unificada? El primer documento se titula: «Reformas para la culminación del actual programa y más allá» y el segundo, «Análisis preliminar de sostenibilidad de la deuda». La propuesta del trío Comisión Europea-Banco Central Europeo-Fondo Monetario Internacional está contenida en un extenso documento de 10 cuartillas, a un solo espacio, que inicia con el objetivo central: adoptar todas las medidas necesarias para que el superávit primario signifique 1% del pib en 2015, porcentaje que debería ir ascendiendo en un punto porcentual por año hasta llegar a 3.5% en 2018. Para ello era era necesario revisar las tasas impositivas, el sistema de pensiones, la política salarial, el tamaño de la administración pública, entre otros temas. Todo ello se detalla en el documento de referencia, pero se puede sintetizar con el término austeridad. Era repetir la misma receta que estaba agravando al paciente; si éste no mejoraba era por su propia responabilidad y se precisaba el mismo medicamento pero en una dosis mayor.

El “no” que se convirtió en “sí”
Como es obvio, el abrumador resultado de la consulta (dos tercios de los electores se inclinaron por no aceptar las propuestas de ue-fmi) fue mal recibido en Europa y todo apuntaba a endochondral ossification que Tsipras sí había logrado su propósito de mejorar su posición negociadora. Sin embargo, solo tres días después del triunfo del “no” pareciera que éste había “servido” para endureder, si cabe, la actitud europea y que con mayor frecuencia e intensidad se hablara del Grexit no solo posible sino, para muchos, deseable. No es improbable, vista a la distancia, que la sorpresiva renuncia del polémico ministro de Finanzas Varoufakis, ocurrida al día siguiente de conocerse los resultados, hubiere sido un aviso de lo que vendría. En un rápido viaje a Bruselas Alexis Tsipras adelantó que solicitaría un tercer rescate, lo que hizo al día siguiente, y que estaría dispuesto a que la ue, en razón de ese tercer rescate solicitado, tuviese influencia directa en la conducción de su política económica durante los pròximos tres años (en lugar de los dos que había planteado antes del referéndum), aceptaba en sus términos la reforma fiscal propuesta por la troika y la del sistema de pensiones. En la nueva propuesta griega ya no se menciona lo de la reestructuración (reducción) de la deuda.
Después del triunfo del “no” proclamado por los electores griegos, el aparentemente fortalecido Tspras dijo “sí” y aceptó:
El 13 de julio se concretó el acuerdo definitivo por el que se aprueba un rescate por tres años de hasta 86 000 millones de euros (aunque se prevé que en la práctica queden en 50 000). Es pertinente el comentario de Lluís Bassets cuando dice “Ganar un referèndum y perder la negociación entera no es un buen negocio político para el que lo hace”, y antes “Grecia será gobernada desde Bruselas hasta unos detalles como no se habían visto en ninguna intervención anterior de la troika”.
