A sideways look at configural encoding: Two different effects of face rotation

Inversion has a disproportionate disruptive effect on the recognition of faces. This may be due to the disruption of holistic or configural encoding employed to recognise upright faces. The paradigm developed by Tanaka and Farah (1993 Quarterly Journal of Experimental Psychology, Section A 46 225 - 246) was used to investigate the effect of 90°(or orthogonal) rotation on configural encoding. Faces learnt in the orthogonal condition were not recognised as well as upright faces, but a whole-face advantage was found in both cases. This whole-face advantage did not occur for inverted faces. It appears that 90° rotation affects recognition but not specifically configural encoding. It is concluded that rotating a face can have at least two different effects on face processing depending on the range of rotation. Implications for the nature of facial dimensions and the expertise account of the inversion effect are considered

“Life within the person comes to the fore”: Pastoral workers’ practice wisdom on using arts in palliative care

Background: Pastoral care (also chaplaincy, spiritual care) assists people to find meaning, personal resources, and connection with self, others, and/or a higher power. Although essential in palliative care, there remains limited examination of what pastoral workers do. This study examined how pastoral workers use and consider the usefulness of art-based modalities. Methods: Qualitative research was used to examine the practice wisdom (tacit practice knowledge) of pastoral workers experienced in using visual arts and music in palliative care. Two focus groups were conducted. Thematic analysis was informed by grounded theory. Results: Six pastoral workers shared information. Three themes emerged. First, pastoral workers use arts as “another tool” to extend scope of practice by assisting patients and families to symbolically and more deeply contemplate what they find “sacred.” Second, pastoral workers’ art affinities inform their aims, assessments, and interactions. Third, pastoral workers perceive that art-based modalities can validate, enlighten, and transform patients and families through enabling them to “multisensorially” (through many senses) feel recognized, accepted, empowered, and/or close to God. Key elements involved in the work’s transformative effects include enabling beauty, ritual, and the sense of “home” being heard, and legacy creation. Discussion and Conclusion: Pastoral workers interpret that offering art-based modalities in palliative care can help patients and families to symbolically deal with painful memories and experiences, creatively engage with that deemed significant, and/or encounter a sense of transcendence. Training in generalist art-based care needs to be offered in pastoral education

Patients’ and caregivers’ contested perspectives on spiritual care for those affected by advanced illnesses: A qualitative descriptive study

Context; Spiritual care refers to practices and rituals addressing spiritual/religious concerns. It supports coping with loss and finding hope, meaning, and peace. Although integral to palliative care, its implementation is challenging. Objective: To understand an Australian cohort of patients’ and caregivers’ perspectives about experiencing and optimizing spiritual care in the context of advanced illness. Methods: Patients and caregivers of patients with #12 month prognosis were recruited from a broader spiritual study via criterion sampling and agreed to opt-in interviews. Participants from an Australian, metropolitan health service received a spiritual care definition and were interviewed. Transcripts were analyzed using qualitative description. Results: 30 patients (17 male; mean age 70 years) and 10 caregivers (six male; mean age 58.9 years) participated. 27 identified as Christian, and 10 had no religion. Participants described multifaceted and contested beliefs about spirituality. Many queried the tangibility of spirituality, but all valued respectful staff who affirmed personhood, that is, each individual’s worth, especially when care exceeded expectations. They also resonated with positive organizational and environmental tones that improved holistic well-being. Participants stressed the importance of the hospital’s welcoming context and skilled care, which comforted and reassured. Conclusion: Although many patients and caregivers did not resonate with the term ‘‘spiritual care,’’ all described how the hospital’s hospitality could affirm their values and strengthen coping. The phrase ‘‘spiritual care and hospitality’’ may optimally articulate and guide care in similar, pluralist inpatient palliative care contexts, recognizing that such care encompasses an interplay of generalist and specialist pastoral care staff and organizational and environmental qualities

Conserving, Distributing and Managing Genetically Modified Mouse Lines by Sperm Cryopreservation

Sperm from C57BL/6 mice are difficult to cryopreserve and recover. Yet, the majority of genetically modified (GM) lines are maintained on this genetic background.Reported here is the development of an easily implemented method that consistently yields fertilization rates of 70+/-5% with this strain. This six-fold increase is achieved by collecting sperm from the vas deferens and epididymis into a cryoprotective medium of 18% raffinose (w/v), 3% skim milk (w/v) and 477 microM monothioglycerol. The sperm suspension is loaded into 0.25 mL French straws and cooled at 37+/-1 degrees C/min before being plunged and then stored in LN(2). Subsequent to storage, the sperm are warmed at 2,232+/-162 degrees C/min and incubated in in vitro fertilization media for an hour prior to the addition of oocyte cumulus masses from superovulated females. Sperm from 735 GM mouse lines on 12 common genetic backgrounds including C57BL/6J, BALB/cJ, 129S1/SvImJ, FVB/NJ and NOD/ShiLtJ were cryopreserved and recovered. C57BL/6J and BALB/cByJ fertilization rates, using frozen sperm, were slightly reduced compared to rates involving fresh sperm; fertilization rates using fresh or frozen sperm were equivalent in all other lines. Developmental capacity of embryos produced using cryopreserved sperm was equivalent, or superior to, cryopreserved IVF-derived embryos.Combined, these results demonstrate the broad applicability of our approach as an economical and efficient option for archiving and distributing mice

A spiral scaffold underlies cytoadherent knobs in Plasmodium falciparum-infected erythrocytes

Much of the virulence of Plasmodium falciparum malaria is caused by cytoadherence of infected erythrocytes, which promotes parasite survival by preventing clearance in the spleen. Adherence is mediated by membrane protrusions known as knobs, whose formation depends on the parasite-derived, knob-associated histidine-rich protein (KAHRP). Knobs are required for cytoadherence under flow conditions, and they contain both KAHRP and the parasite-derived erythrocyte membrane protein PfEMP1. Using electron tomography, we have examined the three-dimensional structure of knobs in detergent-insoluble skeletons of P. falciparum 3D7 schizonts. We describe a highly organised knob skeleton composed of a spiral structure coated by an electron dense layer underlying the knob membrane. This knob skeleton is connected by multiple links to the erythrocyte cytoskeleton. We used immuno-electron microscopy to locate KAHRP in these structures. The arrangement of membrane proteins in the knobs, visualised by high resolution freeze fracture scanning electron microscopy, is distinct from that in the surrounding erythrocyte membrane, with a structure at the apex that likely represents the adhesion site. Thus, erythrocyte knobs in P. falciparum infection contain a highly organised skeleton structure underlying a specialised region of membrane. We propose that the spiral and dense coat organise the cytoadherence structures in the knob, and anchor them into the erythrocyte cytoskeleton. The high density of knobs and their extensive mechanical linkage suggest an explanation for the rigidification of the cytoskeleton in infected cells, and for the transmission to the cytoskeleton of shear forces experienced by adhering cells

PRIMO: an interactive homology modeling pipeline

The development of automated servers to predict the three-dimensional structure of proteins has seen much progress over the years. These servers make calculations simpler, but largely exclude users from the process. In this study, we present the PRotein Interactive MOdeling (PRIMO) pipeline for homology modeling of protein monomers. The pipeline eases the multi-step modeling process, and reduces the workload required by the user, while still allowing engagement from the user during every step. Default parameters are given for each step, which can either be modified or supplemented with additional external input. PRIMO has been designed for users of varying levels of experience with homology modeling. The pipeline incorporates a user-friendly interface that makes it easy to alter parameters used during modeling

Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans

Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in 25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16 regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP, while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium (LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region. Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the refined data for existing association signals, we estimate that these loci now explain ∼38.9% of the familial relative risk of PrCa, an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent signals within the same regio

HSE and Covid at work : a case of regulatory failure

This publication represents the collective work of a team of health and safety experts brought together by IER to review the UK's response to the Covid-19 pandemic, assess the lessons to be learnt and identify areas of weakness that need further attention. It is IER's intention to follow up this work with a more detailed analysis of the UK's health and safety framework, based on discussions with trade unions, health and safety reps, non-organised workers, enforcement bodies and safety specialists. On the fiftieth anniversary of the Robens Report of 1972, which, despite changes in workplace practices, remains the cornerstone of our health and safety laws, the IER will publish its findings and recommendations
