SEVERE BIODEGRADATION OF CRUDE OILS FROM THE QUIRIQUIRE FIELD, EASTERN VENEZUELAN BASIN
Authors: López Liliana , Romero Jesús A. , Lo Mónaco Salvador 
Published: December 2021

Five crude oil samples from the Quiriquire field (Maturin sub‐basin, Eastern Venezuelan Basin) were analysed to evaluate their levels of biodegradation. The oils were obtained from coarse sandstones and conglomerates of the Pliocene Quiriquire Formation at depths <1000 m. Analyses of the samples’ bulk physicochemical parameters indicate variations in API gravity and in the content of saturated hydrocarbons and NSO+asphaltenes, and also in the saturate/aromatic ratio which increases in more biodegraded oils. n‐Alkane distributions are characterized by a dominant unresolved complex mixture (UCM) or hump under an envelope of peaks which lack the acyclic isoprenoids pristane and phytane. The alteration of steranes and terpanes together with the presence of 25‐norhopanes and 17‐nor‐tricyclic terpanes, and the alteration of low molecular‐weight (C20‐C21) triaromatic steroids, phenanthrene, methyl‐phenanthrene, dibenzothiophene and methyl‐dibenzothiophene, indicate that the oils have undergone severe biodegradation.The oils contain compounds with different susceptibilities to biodegradation which is probably a consequence of the mixing of different oil charges in the Quiriquire Formation reservoir. The oils were derived from underlying source rocks in the Upper Cretaceous Guayuta Group (Querecual and San Antonio Formations), and migration into the shallow reservoir at Quiriquire field likely occurred continuously through time. Although the oils have undergone severe biodegradation, it was possible to make some inferences about their origin. Thus, the analyzed oils are interpreted to have originated from marine shale or marl source rocks containing mixed organic matter deposited under anoxic‐suboxic conditions and were generated at near peak oil window maturities.

Published: December 2021

AbstractThe aim of this work was to examine relations between instrumental and sensory parameters in a texture modified food matrix, with and without saliva. Nine pureed carrot samples (eight thickened and a control) were developed with starch (0.4 and 0.8% wt/wt), xanthan (0.2 and 0.4% wt/wt) or starch–xanthan blends that met International Dysphagia Diet Standardisation Initiative (IDDSI) Level 4 guidelines using fork and spoon tests. Rheological and tribological tests were conducted on the food and simulated bolus prepared by adding fresh stimulated saliva to the food (1:5, saliva:food) to mimic oral processing. Perceived sensory properties were identified using a temporal dominance of sensations (TDS) test (n = 16) where panelists were given a list of nine attributes. The area under the curve was extracted from TDS curves for each attribute/sample and this was correlated with rheological (viscosity at 10 s−1, G′, G″, and tan δ at 1 Hz) and tribological (friction coefficient in three regimes) data. The viscosity of the control sample decreased after adding hydrocolloids (except Starch_0.8%) and with saliva incorporation. G′ and G″ either increased or were similar for xanthan and blends and decreased for starch‐thickened samples. Hydrocolloid addition increased friction for all samples and was higher with saliva addition. Sensory results showed that samples with starch were perceived as thick and grainy while xanthan was perceived as smooth and slippery. A greater number of sensory attributes correlated with viscoelastic parameters compared to friction coefficients. Correlations were highest with the saliva added samples, further highlighting the importance of including saliva during instrumental testing.
Comfort over safety: thermoregulation overshadows predation risk effects in the activity of a keystone prey

AbstractThe activity level is a fundamental metric of animal behavior, related to the avoidance of predators, food acquisition, and thermoregulation. Animals need to weigh their activity budget to fulfill their energetic, social and reproductive requirements over the energetic costs of these activities. This task becomes further challenging for prey species, which also need to account for predation risk. To investigate the factors shaping proactive behavioral decisions leading prey species engagement in their diel activities, we implemented a multisite year‐round monitoring study on the Iberian rabbit (Oryctolagus cuniculus algirus), a key prey species in Mediterranean ecosystems. We deployed remotely triggered cameras over 15 sites to continuously monitor Iberian rabbits' activity. We estimated activity levels from time‐of‐detection data from camera traps, and modeled it as a function of climatic, intraspecific, predation, and resource‐related covariates. We found that Iberian rabbits exhibit a bimodal activity pattern peaking at sunrise and sunset, with a more pronounced peak occurring at sunrise during the nonbreeding season, and spend 9.15 ± 3.00 h/day (mean ± sd) active. Diel activity levels were negatively affected by extreme environmental temperatures and density dependence, demonstrating the privileged importance of social interactions and normothermia maintenance. We found mammalian predator activity and abundance to have near‐negligible effects on the activity levels of this key prey, suggesting decreased antipredator behavior when risk is perceived as prolonged. Moreover, we argue that perceived risk may be more important than realized risk in shaping Iberian rabbits' activity level. These results provide valuable insights toward a comprehensive understanding of the factors underlying behavioral decisions made by prey species, relevant for maintaining their energetic and homeostatic balance.

Published: December 2021

AbstractSeveral Peronospora species are carried by wind over short and long distances, from warmer climates where they survive on living plants to cooler climates. In eastern Canada, this annual flow of sporangia was thought to be the main source of Peronospora destructor responsible for onion downy mildew. However, the results of a recent study showed that the increasing frequency of onion downy mildew epidemics in eastern Canada is associated with warmer autumns, milder winters, and previous year disease severity, suggesting overwintering of the inoculum in an area where the pathogen is not known to be endogenous. In this study, genotyping by sequencing was used to investigate the population structure of P. destructor at the landscape scale. The study focused on a particular region of southwestern Québec—Les Jardins de Napierville—to determine if the populations were clonal and regionally differentiated. The data were characterized by a high level of linkage disequilibrium, characteristic of clonal organisms. Consequently, the null hypothesis of random mating was rejected when tested on predefined or nonpredefined populations, indicating that linkage disequilibrium was not a function of population structure and suggesting a mixed reproduction mode. Discriminant analysis of principal components performed with predefined population assignment allowed grouping P. destructor isolates by geographical regions, while analysis of molecular variance confirmed that this genetic differentiation was significant at the regional level. Without using a priori population assignment, isolates were clustered into four genetic clusters. These results represent a baseline estimate of the genetic diversity and population structure of P. destructor.

Summary

Sun‐induced fluorescence in the far‐red region (SIF) is increasingly used as a remote and proximal‐sensing tool capable of tracking vegetation gross primary production (GPP). However, the use of SIF to probe changes in GPP is challenged during extreme climatic events, such as heatwaves.

Here, we examined how the 2018 European heatwave (HW) affected the GPP–SIF relationship in evergreen broadleaved trees with a relatively invariant canopy structure. To do so, we combined canopy‐scale SIF measurements, GPP estimated from an eddy covariance tower, and active pulse amplitude modulation fluorescence.

The HW caused an inversion of the photosynthesis–fluorescence relationship at both the canopy and leaf scales. The highly nonlinear relationship was strongly shaped by nonphotochemical quenching (NPQ), that is, a dissipation mechanism to protect from the adverse effects of high light intensity. During the extreme heat stress, plants experienced a saturation of NPQ, causing a change in the allocation of energy dissipation pathways towards SIF.

Our results show the complex modulation of the NPQ–SIF–GPP relationship at an extreme level of heat stress, which is not completely represented in state‐of‐the‐art coupled radiative transfer and photosynthesis models.
An endogenous basis for synchronisation characteristics of the circadian rhythm in proliferating Lemna minor plants
Authors: Ueno Kenya , Ito Shogo , Oyama Tokitaka 
Published: December 2021

Summary

The circadian clock is a cell‐autonomous system that functions through the coordination of time information in the plant body. Synchronisation of cellular clocks is based on coordination mechanisms; the synchronisation characteristics of proliferating plants remain unclear.

The bioluminescence circadian rhythms of fronds (leaf‐like plant units) of proliferating Lemna minor plants carrying a circadian bioluminescence reporter, AtCCA1:LUC, were spatiotemporally analysed at a cell‐level resolution. We focused on spontaneous circadian organisation under constant light conditions for plants with light : dark treatment (LD grown) or without it (LL grown).

Fronds developing even from an LL‐grown parental frond showed coherent circadian rhythms among them. This allowed the maintenance of circadian rhythmicity in proliferating plants. Inside a frond, a centrifugal phase/period pattern was observed in LD‐grown plants, whereas various phase patterns with travelling waves were formed in LL‐grown plants. These patterns were model simulated by local coupling of heterogeneous cellular circadian oscillators with different initial synchronous states in fronds.

Spatiotemporal analysis of the circadian rhythms in proliferating plants reveals spontaneous synchronisation manners that are associated with local cell–cell coupling, spatial phase patterns and developmental stages.
“He fumbles at your Soul”: Emily Dickinson between the piano and the cosmos
Authors: Thomières Daniel 
Published: December 2021

AbstractThis essay is an attempt at unfolding the semantic implications of a sonnet by Emily Dickinson, through layer after layer of meaning, “He fumbles at your Soul.” The poem, which relates a traumatic experience, can be analyzed as an experiment in which the poet explores language, going as far as is possible in order to fathom its potential. The notion of identity is interrogated as a series of more or less conventional modes of being, which, at its deepest level, questions the meaning of life. The subject is shown as constituted by concrete metamorphoses poised between nature and culture, as well as between death and life. In conclusion, the poem puts forward an original conception of death: death is a plurality which reveals new possibilities of life.
Sublingual immunization with recombinant GroEL plus CpG‐ODN inhibits Porphyromonas gingivalis‐induced inflammation and alveolar bone loss

Published: December 2021

AbstractIt has been reported that GroEL, a heat shock protein (HSP) produced by the representative periodontopathogenic bacterium, Porphyromonas gingivalis, induces inflammation‐induced osteoclastogenesis and promotes alveolar bone resorption. In this study, we demonstrated the efficacy of a mucosal vaccine targeting GroEL against bone resorption induced by P. gingivalis. Female BALB/c mice received sublingual CpG oligodeoxynucleotide as an adjuvant with recombinant GroEL (rGroEL) prior to P. gingivalis exposure. Animals were euthanized 30 days after P. gingivalis inoculation. Sublingual immunization (SLI) with rGroEL elicited significant rGroEL‐specific serum immunoglobulin (Ig)G and salivary IgA antibody (Ab) responses, and these responses were sustained for approximately 1 year. Interestingly, 10‐fold more GroEL‐specific IgA Ab‐producing cells were detected in the submandibular glands (SMGs) than in the spleen. Antigen (Ag)‐specific cells isolated from the spleen and SMGs induced significantly higher levels of IFN‐γ expression after Ag restimulation in vitro. Flow cytometry illustrated that the frequency of CD11b+ dendritic cells with enhanced expression of CD80, CD86, CD40, and major histocompatibility complex II molecules was significantly increased in the SMGs. Furthermore, SLI with rGroEL significantly suppressed P. gingivalis‐induced alveolar bone resorption and P. gingivalis‐stimulated tumor necrosis factor‐α, interleukin‐6, and HSP60 expression in the gingiva.These findings suggest that SLI with rGroEL and CpG oligodeoxynucleotide is a beneficial strategy for preventing periodontal disease, mainly by presenting Ags in the oral region and inducing antibody production in the mucosal and systemic systems.
Can I leave my hat on? A cross‐level study of multiple team membership role separation
Authors: van de Brake Hendrik J. , Berger Stefan 
Published: December 2021

AbstractThis article conceptualizes role separation in multiple team membership (MTM) (i.e., the extent to which a multiteamer's role within a focal team is different from his/her role in another team) as a key predictor of individual and team outcomes. Existing literature on MTM focuses primarily on the total number of concurrent teams that an individual contributes to, and thus largely ignores the potential diversity that may characterize MTM. In Study 1, we develop and validate a measure of MTM role separation that reflects differences in (a) expected work results; (b) team collaboration; (c) leader expectations; and (d) client and/or customer characteristics. In Study 2, we use field data to examine the cross‐level implications of MTM role separation. As expected, we find that MTM role separation is positively related to a multiteamer's role ambiguity within a focal team and, by extension, harms the performance of the entire focal team. This indirect relationship is not observed when a focal team's teamwork quality (TWQ) is high. We discuss how these findings advance our understanding of the multifaceted and multi‐level nature of MTM and help multiteamers, team leaders, and organizations deal with MTM's challenges.

Abstract

Iron (Fe) is an essential element for plant growth and development. Fe deficiency can trigger leaf chlorosis and reduce fruit yield. Therefore, it is necessary to explore transcription factors in response to Fe deficiency stress.

A total of 29 MhR2R3‐MYB transcription factors were identified based on the transcriptome of Malus halliana under Fe deficiency stress. A comprehensive analysis of physical and chemical properties, gene structures, conserved motif composition, evolutionary relationship and chromosome distribution was performed. Subsequently, based on the transcriptome, 14 genes with the most significant expression under Fe deficiency stress were screened for qRT‐PCR verification. Among them,the functional characteristics of MhR2R3‐MYB4 (MD05G1089600) were further studied in Arabidopsis thaliana.

Expression of 13 out of these 14 genes was upregulated, only one was downregulated. Maximum upregulation of MhR2R3‐MYB4 under Fe deficiency was 36.39‐fold and 58.21‐fold compared with day 0 in leaves and roots, respectively. Overexpression of MhR2R3‐MYB4 enhanced tolerance to Fe deficiency in A. thaliana and led to multiple biochemical changes: transgenic lines have higher chl a, chl b and Fe2+ content, higher enzyme activity (SOD, POD, CAT and FCR) and lower chlorosis than the wild type in Fe deficiency conditions.

We suggest that MhR2R3‐MYB4 plays an important part in Fe deficiency stress, which may contribute to improve Fe deficiency tolerance of apple in future.

Published: December 2021

AbstractThe emergence and prevalence of bacterial pathogens in freshwater aquaculture systems is a growing concern as the economic losses associated with diseases are mounting and impacting the fishery sector. One way of controlling fish mortality and morbidity is using bacteriocin‐secreting probiotics, which are generally considered safe without any adverse effects that usually accompany other treatment strategies. Understanding the mode of action of bacteriocin on pathogens is vital for considering them suitable for application as a prophylactic in aquaculture. Although several measures such as antibiotic treatment, chemotherapy, vaccination, etc., are available, though not without concerns, these methods have limitations for field‐level applications since they result in several adverse effects both for the animals and the aquatic environment affecting several species in the food chain. In this situation, the use of bacteriocin can be an excellent alternative to minimize the disease burden in freshwater aquaculture if delivered appropriately. Here, we provide an update on the various bacteriocins and their mode of action against important pathogens encountered in aquaculture.
A family‐centred perspective on the arteriovenous fistula in end‐stage renal disease: Findings from dyadic interviews
Authors: Sousa Helena , Bártolo Ana , Ribeiro Oscar , Figueiredo Daniela 
Published: December 2021

AbstractIntroductionThe preservation of a well‐functioning arteriovenous fistula (AVF) is crucial for successful dialysis in patients with end‐stage renal disease (ESRD); nonetheless, complications are frequent which leads to lower quality of life, hospitalisations and death. Self‐care behaviours help to reduce the risk of complications and family caregivers can play an important role as partners for behaviour change. However, the patient and family caregiver's experiences with such an invasive intervention are largely unknown.AimsThis study aimed to explore the experiences of patients with ESRD and their family caregivers with the AVF through joint interviews.MethodsA qualitative exploratory study was conducted with a purposive sample. Semi‐structured joint interviews were conducted with 14 dyads (28 participants) composed of patients on haemodialysis with AVF and their respective family caregivers. Interviews were audiotaped, transcribed verbatim and submitted to thematic analysis.FindingsFour major themes were identified: (i) AVF negative impacts; (ii) (un)presence of self‐care behaviours; (iii) AVF self‐management facilitators and (iv) AVF self‐management barriers.DiscussionThe findings suggested that more attention needs to be paid to patients’ and their family caregivers’ support needs (e.g. fears, concerns, knowledge, adherence barriers and facilitators) regarding AVF self‐management. The dyads seem to be aware of how to take care of the AVF; however, self‐care behaviours still need to be improved.ConclusionInnovative interventions need to follow an interdisciplinary approach with an educational and support component. The integration of family caregivers should also be considered, since this study evidenced their lack of knowledge and skills, and willingness to participate in these initiatives.
Not seeing the elephant in the room: How policy discourses shape frontline work with child poverty
Authors: Nørup Iben , Jacobsen Betina 
Published: December 2021

AbstractBased on strong discourses of individualization, active welfare reforms in Denmark have changed the financial security of vulnerable families and increased numbers of children are growing up in poverty. This study investigates how poverty is reflected in frontline workers' categorizations of children considered vulnerable. Empirically, the study draws on qualitative group interviews with 56 informants and descriptive results from two surveys with almost 2000 respondents each. Findings are analysed using Foucault's theory of disciplinary power. The findings give an important insight as to how policy discourse influences and steers the moral and professional judgement in the frontline and why social work with vulnerable clients takes on particular forms. The results show that frontline workers implement and reproduce an individualised discourse found in recent social policy reforms while overlooking societal structures defining the individual's possibilities. In particular, poverty is left unrecognised, as categorizations of ‘normal’ versus ‘vulnerable’ revolve around family relations and perception of personal shortcomings of the parents.
