Short-term trajectories of workplace bullying and its impact on strain: A latent class growth modeling approach
The aim of this weekly diary study was (a) to identify trajectories of workplace bullying over time and (b) to examine the association of each cluster with strain indicators (i.e., insomnia and anxiety/depression). A sample of 286 employees during 4 weeks of data was used (N occasions = 1,144). Results of latent class growth modeling showed that 3 trajectories could be identified: a nonbullying trajectory, which comprised 90.9% of the sample; an inverted U trajectory; and a delayed increase bullying trajectory; the latter two each had 4.2% of the participants. We found a significant interaction between time and trajectories when predicting insomnia and anxiety/depression, with each strain showing a differential pattern with each trajectory. It seems that the negative effects on insomnia are long-lasting and remain after bullying has already decreased. In the case of anxiety and depression, when bullying decreases strain indicators also decrease. In this study, by examining trajectories of bullying at work over time and their associations with strain, we provide new insights into the temporal dynamics of workplace bullying
Ripple Effects of Surface acting: A Diary Study among Dual-earner Couples
This study among 80 dual-earner couples examines the ripple effects of emotional labour – on a daily basis. Specifically, we propose that employees who engage in surface acting at work drain their energetic resources, and undermine their own relationship satisfaction. Drawing upon conservation of resources (COR) theory, we predicted that work-related exhaustion would mediate the relationship between surface acting at work and at home. In addition, we hypothesized that employees’ emotional energy in the evening would mediate the relationship between surface acting at home and (actor and partner) satisfaction with the relationship. Participants filled in a survey and a diary booklet during five consecutive working days (N = 80 couples, N = 160 participants x 5 days, N = 800 occasions). The hypotheses were tested with multilevel analyses, using the actor–partner interdependence model. Results showed that daily work-related exhaustion partially mediated the relationship between daily surface acting at work and at home. As hypothesized, daily surface acting at home influenced own and partner’s daily relationship satisfaction through reduced daily emotional energy. These findings offer support for COR theory, and have important implications for organizations that encourage emotion regulation
Gamma Irradiation of Magnetoresistive Sensors for Planetary Exploration
A limited number of Anisotropic Magnetoresistive (AMR) commercial-off-the-shelf (COTS) magnetic sensors of the HMC series by Honeywell, with and without integrated front-end electronics, were irradiated with gamma rays up to a total irradiation dose of 200 krad (Si), following the ESCC Basic Specification No. 22900. Due to the magnetic cleanliness required for these tests a special set-up was designed and successfully employed. Several parameters of the sensors were monitored during testing and the results are reported in this paper. The authors conclude that AMR sensors without front-end electronics seem to be robust against radiation doses of up to 200 krad (Si) with a dose rate of 5 krad (Si)/hour and up to a resolution of tens of nT, but sensors with an integrated front-end seem to be more vulnerable to radiation

What Neanderthals and AMH ate: reassessment of the subsistence across the Middle–Upper Palaeolithic transition in the Vasco‐Cantabrian region of SW Europe
ABSTRACT: Recent research in northern Spain has revealed the disappearance of Neanderthal populations in the Vasco‐Cantabrian region a few millennia earlier than in eastern and southern Iberia and discovered a short period of overlap with modern humans, at least, in terms of radiocarbon dates. However, the causes of Neanderthal decline understood as a regional and temporal process remain open. Despite the abundance of technological studies, modern‐quality chronological dating, and the availability of archaeofaunal and palaeoenvironmental data, there is a lack of consensus about how climatic and environmental conditions could have affected ungulate prey and, therefore, Neanderthal subsistence strategies. In this paper, an analytical summary of the archaeofaunal and taphonomic data available for the Vasco‐Cantabrian region, combined with the most recent chronological evidence, present general knowledge about animal biogeography and ecology during the Middle–Upper Palaeolithic transition, and provides an interpretation of the behaviour of both human species in the region. This work reviews the palaeomammal community of animals represented in the record as exploited by human groups in several caves and rock shelters and pointing to continuing lacunae in knowledge. Further research is needed to verify and potentially explain the apparent hominin population gap and the ultimate fate of the Neanderthals
Positive Experiences at Work and Daily Recovery: Effects on Couple’s Well-Being
The present diary study investigates, at the within-person level, how job satisfaction mediates the relationship between self-rated job performance and recovery experiences (i.e., psychological detachment from work and relaxation) during off-job time. Furthermore, we explore the effects of these two recovery experiences on couple´s well-being. Data were collected from 145 dual-earner couples (N = 290 participants; N = 1450 occasions) with a daily diary design (five consecutive working days). Multilevel analyses showed that daily job performance positively predicted psychological detachment and relaxation, and that daily job satisfaction partially mediated this relationship. In addition, we found that psychological detachment and relaxation have positive effects on own and partner´s indicators of well-being (i.e., relationship satisfaction and positive emotions). The benefits of recovery go beyond the individual and affect their partner´s level of well-being
A novel eIF4E-interacting protein that forms non-canonical translation initiation complexes
Translation is a fundamental step in gene expression that regulates multiple developmental and stress responses. One key step of translation initiation is the association between eIF4E and eIF4G. This process is regulated in different eukaryotes by proteins that bind to eIF4E; however, evidence of eIF4E-interacting proteins able to regulate translation is missing in plants. Here, we report the discovery of CERES, a plant eIF4E-interacting protein. CERES contains an LRR domain and a canonical eIF4E-binding site. Although the CERES–eIF4E complex does not include eIF4G, CERES forms part of cap-binding complexes, interacts with eIF4A, PABP and eIF3, and co-sediments with translation initiation complexes in vivo. Moreover, CERES promotes translation in vitro and general translation in vivo, while it modulates the translation of specific mRNAs related to light and carbohydrate response. These data suggest that CERES is a non-canonical translation initiation factor that modulates translation in plants.This research has received funding from the European Research Council under the European Union's Seventh Framework Programme (FP/2007-2013) / ERC Grant Agreement n. 260468 to M.M.C. and from the grant S2013- ABI2748 from CAM.

Identification by proximity labeling of novel lipidic and proteinaceous potential partners of the dopamine transporter
Dopamine (DA) transporters (DATs) are regulated by trafficking and modulatory processes that probably rely on stable and transient interactions with neighboring proteins and lipids. Using proximity-dependent biotin identification (BioID), we found novel potential partners for DAT, including several membrane proteins, such as the transmembrane chaperone 4F2hc, the proteolipid M6a and a potential membrane receptor for progesterone (PGRMC2). We also detected two cytoplasmic proteins: a component of the Cullin1-dependent ubiquitination machinery termed F-box/LRR-repeat protein 2 (FBXL2), and the enzyme inositol 5-phosphatase 2 (SHIP2). Immunoprecipitation (IP) and immunofluorescence studies confirmed either a physical association or a close spatial proximity between these proteins and DAT. M6a, SHIP2 and the Cullin1 system were shown to increase DAT activity in coexpression experiments, suggesting a functional role for their association. Deeper analysis revealed that M6a, which is enriched in neuronal protrusions (filopodia or dendritic spines), colocalized with DAT in these structures. In addition, the product of SHIP2 enzymatic activity (phosphatidylinositol 3,4-bisphosphate [PI(3,4)P2]) was tightly associated with DAT, as shown by co-IP and by colocalization of mCherry-DAT with a specific biosensor for this phospholipid. PI(3,4)P2 strongly stimulated transport activity in electrophysiological recordings, and conversely, inhibition of SHIP2 reduced DA uptake in several experimental systems including striatal synaptosomes and the dopaminergic cell line SH-SY5Y. In summary, here we report several potential new partners for DAT and a novel regulatory lipid, which may represent new pharmacological targets for DAT, a pivotal protein in dopaminergic function of the brainOpen Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.

Gender, albuminuria and chronic kidney disease progression in treated diabetic kidney disease
Background: Women are reported to have a lower incidence of renal replacement therapy,
despite a higher prevalence of chronic kidney disease (CKD). Aim: To analyze diabetic kidney
disease (DKD) progression in men and women. Methods: Prospective cohort: n = 261, 35% women,
new consecutive nephrology DKD referrals. Results: Women smoked less and better complied
with the dietary phosphate and sodium restrictions. Despite a less frequent nephrology referral,
women had lower baseline albuminuria. Over a 30 + - 10-month follow-up, albuminuria decreased in
women and the estimated glomerular filtration rate (eGFR) loss was slower than in men. However,
the percentage of rapid progressors was similar in both sexes. The best multivariate model predicting
rapid progression in men (area under curve (AUC) = 0.92) and women differed. Albuminuria and
fractional excretion of phosphate (FEphosphate) were part of the men multivariable model, but not of
women. The AUC for the prediction of rapid progression by albuminuria was higher in men than in
women, and the albuminuria cut-off points also differed. In women, there was a higher percentage of
rapid progressors who had baseline physiological albuminuria. Conclusions: Female DKD differs
from male DKD: albuminuria was milder and better responsive to therapy, the loss of eGFR was
slower and the predictors of rapid progression differed from men: albuminuria was a better predictor in men than in women. Lifestyle factors may contribute to the differencesThis work and the APC was funded by FIS grant numbers CP14/00133, PI16/02057, PI18/01366,

Valorization of brewer’s spent grain by furfural recovery/removal from subcritical water hydrolysates by pervaporation
This work is focused on the development of a sustainable process for the valorisation of the main by-product
generated in the brewing industry, the brewer’s spent grain (BSG). A two-step process combining subcritical
water treatment and pervaporation (PV) was proposed to hydrolyse the hemicelluloses fraction of this lignocellulosic biomass and further removal/recovery of some of the degradation products of sugars by using two
different organophilic membranes, polydimethylsiloxane (PDMS) and polyoctilmethylsiloxane (POMS) membranes. Specifically, furfural is the dehydration product of pentoses and it is one of the top biomass-based
chemicals being an important platform chemical. For synthetic binary mixtures, lower total permeation flux
but higher enrichment factors for furfural were determined for POMS. When dealing with subW hydrolysates,
POMS membranes yielded the highest furfural recovery, 94.1 %, with permeate concentrations as high as 40 g⋅L1
. Furthermore, it was assessed that PV is a suitable detoxification method that yielded a retentate nearly free of
furfural allowing its use as growth media in the opposite to the subW hydrolysate with inhibitory furfural
concentrations for microbial bioprocesses.publishe
