Cellular Mechanisms of Slime Gland Refilling in Pacific Hagfish (\u3cem\u3eEptatretus stoutii\u3c/em\u3e)

Hagfishes use their defensive slime to ward off gill-breathing predators. Slime gland refilling is a surprisingly slow process, and previous research has shown that the composition of the slime exudate changes significantly during refilling, which likely has consequences for the functionality of the slime. This study set out to expand our understanding of slime gland refilling by examining the cellular processes involved in refilling of the glands, as well as determining where in the gland the main slime cells – the gland thread cells and gland mucous cells – arise. Slime glands were electro-stimulated to exhaust their slime stores, left to refill for set periods of time, and harvested for histological and immunohistochemical examination. Whole slime glands, gland thread cell morphometrics and slime cell proportions were examined over the refilling cycle. Slime glands decreased significantly in size after exhaustion, but steadily increased in size over refilling. Gland thread cells were the limiting factor in slime gland refilling, taking longer to replenish and mature than gland mucous cells. Newly produced gland thread cells underwent most of their growth near the edge of the gland, and larger cells were found farthest from the edge of the gland. Immunohistochemical analysis also revealed proliferating cells only within the epithelial lining of the slime gland, suggesting that new slime cells originate from undifferentiated cells lining the gland. Our results provide an in-depth look at the cellular dynamics of slime gland refilling in Pacific hagfish, and provide a model for how slime glands refill at the cellular level

Emptying and Refilling of Slime Glands in Atlantic (\u3cem\u3eMyxine glutinosa\u3c/em\u3e) and Pacific (\u3cem\u3eEptatretus stoutii\u3c/em\u3e) Hagfishes

Hagfishes are known for their unique defensive slime, which they use toward off gill-breathing predators. Although much is known about the slime cells (gland thread cells and gland mucous cells), little is known about how long slime gland refilling takes, or how slime composition changes with refilling or repeated stimulation of the same gland. Slime glands can be individually electrostimulated to release slime, and this technique was used to measure slime gland refilling times for Atlantic and Pacific hagfish. The amount of exudate produced, the composition of the exudate and the morphometrics of slime cells were analyzed during refilling, and as a function of stimulation number when full glands were stimulated in rapid succession. Complete refilling of slime glands for both species took 3–4 weeks, with Pacific hagfish achieving faster absolute rates of exudate recovery than Atlantic hagfish. We found significant changes in the composition of the exudate and in the morphometrics of slime cells from Pacific hagfish during refilling. Over successive stimulations of full Pacific hagfish glands, multiple boluses of exudate were released, with exudate composition, but not thread cell morphometrics, changing significantly. Finally, histological examination of slime glands revealed slime cells retained in glands after exhaustion. Discrepancies in the volume of cells released suggest that mechanisms other than contraction of the gland musculature alone may be involved in exudate ejection. Our results provide a first look at the process and timing of slime gland refilling in hagfishes, and raise new questions about how refilling is achieved at the cellular level

Patient Perception of Physician Attire in a Military Ophthalmology Clinic

The purpose of this study is to investigate patient preferences of physician attire in an outpatient military ophthalmology clinic to determine how these preferences affect patients' perceptions of physician competence and their overall clinical experience. Materials and methods This study is a prospective survey administered to patients at the ophthalmology clinic at Brooke Army Medical Center. USA. Patients who were willing to participate in a volunteer survey were included in this study. Demographic information and survey questions were utilized in this study along with words and pictures for patients to select a preference in physician attire in the clinic setting (scrubs, military uniform, or civilian professional attire) and surgical setting (surgical cap or a surgical bouffant). The survey asks patients if physician attire impacts patient confidence in physician abilities (yes or no) and if surgeon attire impacts the likelihood of the patient taking the surgeon's advice (yes or no). Results The demographic distribution includes 57-77 years old participants (53%), females (61%), retirees (49%), and dependent spouses (40%). The racial distribution includes 46% - Caucasian, 20% - African American, 22% - Hispanic, 6 - % Asian, and 6% - other. Most patient appointment types were established follow-up (77%) with only 12% new and 11% walk-in. The survey results (N=308) indicate that most patients (64%) did not have a preference in physician clinical attire, while 22% preferred scrubs, 11% preferred military uniform, and 3% preferred civilian attire. Most patients (66%) did not have a preference for surgical headwear, while 27% preferred the surgical cap, and 7% preferred the surgical bouffant. Only 9% of the patients surveyed indicated that physician attire impacted their confidence in their physician's ability, and 12% reported that attire impacted the likelihood of taking advice. Conclusions Most patients in an outpatient military ophthalmology clinic do not have a preference for physician attire or surgical headwear when surveyed. The majority of patients did not feel physician attire impacted their perception of physician's ability or their likelihood of taking advice. When indicating a preference, patients tended to prefer scrubs to outpatient civilian attire or military attire and trended towards preferring surgical cap over surgical bouffant for headwear

Diversity in numbers – cultivating a growth mindset for numeracy development

Developing a solid foundation in quantitative skills (QS, e.g., numeracy, statistics) is essential for students’ academic success. More broadly, numeracy is a core language for understanding and developing critical thinking around current and future challenges in sustainability, artificial intelligence and climate change. However, Australian tertiary QS teaching is often limited to one 100-level unit and between 1-3 units later in the degree (Matthews et al., 2012). This provides little opportunity for vertical scaffolding of QS or even STEM students’ recognition of QS as an essential element of their learning, as QS development is not prioritised in their courses. The ACDS-funded Diversity in Numbers (DiN) project evaluates an alternative curricular model for numeracy skills development within the science curriculum: scaffolded, course-wide implementation of digital numeracy modules with embedded interactive content and rich automated feedback to maximise learning. Pilot modules have been developed, each focusing on a core QS concept (e.g., statistical testing, unit conversions). Modules are framed around a published article relevant to unit content, with the goal of broadening student awareness of how numbers can be used to explore global diversity. By promoting a culture of inclusivity and diversity, where students can see themselves within the curriculum, we aim to foster a sense of belonging among our diverse undergraduate students, supporting the emergence of an increasingly diverse scientific community. Preliminary qualitative findings from student focus groups during semester two 2022 will be presented, considering the implications of DiN modules on student engagement and learning, numeracy anxiety and awareness of diversity. A major finding of this work was that most students in the focus group displayed a fixed mindset to QS, although we did see some variability depending on the context in which students received their school-level mathematics education. While most students could recognise a fixed mindset around maths, leading to anxiety or avoidance of QS, students educated outside the Australian education system were not constrained by this. From these findings, it seems that fostering a growth mindset around QS development is a crucial first step in engaging Australian students with university-level numeracy concepts. We propose that participating in scaffolded QS modules that sit outside the graded curriculum and offer formative feedback may support students to develop a growth mindset towards QS.

Robot Assisted Surgical Ward Rounds: Virtually Always There

Background:  While an explosion in technological sophistication has revolutionized surgery within the operating theatre, delivery of surgical ward-based care has seen little innovation.  Use of telepresence allowing off-site clinicians communicate with patients has been largely restricted to outpatient settings or use of complex, expensive, static devices.  We designed a prospective study to ascertain feasibility and face validity of a remotely controlled mobile audiovisual drone (LUCY) to access inpatients.  This device is, uniquely, lightweight, freely mobile and emulates ‘human’ interaction by swiveling and adjusting height to patients’ eye-level.   Methods: Robot-assisted ward rounds(RASWR) were conducted over 3 months. A remotely located consultant surgeon communicated with patients/bedside teams via encrypted audiovisual telepresence robot (DoubleRoboticstm, California USA).  Likert-scale satisfaction questionnaires, incorporating free-text sections for mixed-methods data collection, were disseminated to patient and staff volunteers following RASWRs.  The same cohort completed a linked questionnaire following conventional (gold-standard) rounds, acting as control group. Data were paired, and non-parametric analysis performed.  Results: RASWRs are feasible (>90% completed without technical difficulty). The RASWR(n=52 observations) demonstrated face validity with strong correlations (r>0.7; Spearman, p-value <0.05) between robotic and conventional ward rounds among patients and staff on core themes, including dignity/confidentiality/communication/satisfaction with management plan. Patients (96.08%, n=25) agreed RASWR were a satisfactory alternative when consultant physical presence was not possible. There was acceptance of nursing/NCHD cohort (100% (n=11) willing to regularly partake in RASWR).  Conclusion: RASWRs receive high levels of patient and staff acceptance, and offer a valid alternative to conventional ward rounds when a consultant cannot be physically present

Comparing the interobserver reproducibility of different regions of interest on multi-parametric renal magnetic resonance imaging in healthy volunteers, patients with heart failure and renal transplant recipients

Objective: To assess interobserver reproducibility of different regions of interest (ROIs) on multi-parametric renal MRI using commercially available software. Materials and methods: Healthy volunteers (HV), patients with heart failure (HF) and renal transplant recipients (Tx) were recruited. Localiser scans, T1 mapping and pseudo-continuous arterial spin labelling (pCASL) were performed. HV and Tx also underwent diffusion-weighted imaging to allow calculation of apparent diffusion coefficient (ADC). For T1, pCASL and ADC, ROIs were drawn for whole kidney (WK), cortex (Cx), user-defined representative cortex (rep-Cx) and medulla. Intraclass correlation coefficient (ICC) and coefficient of variation (CoV) were assessed. Results: Forty participants were included (10 HV, 10 HF and 20 Tx). The ICC for renal volume was 0.97 and CoV 6.5%. For T1 and ADC, WK, Cx, and rep-Cx were highly reproducible with ICC ≥ 0.76 and CoV &lt; 5%. However, cortical pCASL results were more variable (ICC &gt; 0.86, but CoV up to 14.2%). While reproducible, WK values were derived from a wide spread of data (ROI standard deviation 17% to 55% of the mean value for ADC and pCASL, respectively). Renal volume differed between groups (p &lt; 0.001), while mean cortical T1 values were greater in Tx compared to HV (p = 0.009) and HF (p = 0.02). Medullary T1 values were also higher in Tx than HV (p = 0.03), while medullary pCASL values were significantly lower in Tx compared to HV and HF (p = 0.03 for both). Discussion: Kidney volume calculated by manually contouring a localiser scan was highly reproducible between observers and detected significant differences across patient groups. For T1, pCASL and ADC, Cx and rep-Cx ROIs are generally reproducible with advantages over WK values

Policing mining: In outer-space greed and domination vs. peace and equity a governance for humanity!

Staking claim and ownership has remained an antagonistic issue for nations, resulting in many international conflicts. This is particularly so in disputed territories or areas which are deemed the heritage of mankind. In the next 50-years mining in space is set to become a reality and rather than being used to become an asset to man/society and create an equitable world, it is likely to be a battleground for greed and sovereign dominance – an overspill from Earth. This paper researches the conflict between greed and dominance vs. peace and equity in respect to space - mineral resources, providing historical contextualization, opinion, thoughts and interpretation. Hence, consideration is given to international approaches and who should ‘police,’ plus the governance of, space riches. The research largely considers the stance of the USA in this respect. The relevance of travel and travel modes (particularly air) and ownership of the sky is reviewed, so as to provide comparison and (historical) contextualization – identifying issues previously encountered when man looks to both travel and acquire assets by these means. The latest position of asteroid mining is also explored and ‘lessons from Earth’ are revisited as part of this research – which is largely considered and undertaken from a legal (discipline) perspective

Experiences of caregivers of children with inherited metabolic diseases: a qualitative study

Background: We sought to understand the experiences of parents/caregivers of children with inherited metabolic diseases (IMD) in order to inform strategies for supporting patients and their families. We investigated their experiences regarding the management of disease, its impact on child and family life, and interactions with the health care system. Methods: From four Canadian centres, we conducted semi-structured telephone interviews with parents/caregivers of children with an IMD who were born between 2006 and 2015 and who were participating in a larger cohort study. Participants were selected with the aim of achieving a diverse sample with respect to treatment centre, IMD, and age of the child. Interviews emphasized the impacts of the disease and its treatment on the child and family and explicitly queried perceptions of interactions with the health care system. We identified emergent themes from the interview data. Results: We completed interviews with 21 parents/caregivers. The 21 children were aged \u3c1 to 7 years old with IMD that included amino acid disorders, urea cycle disorders, fatty acid oxidation disorders, and organic acid disorders or \u27other\u27 IMD. Most parents reported that they and their families had adapted well to their child\u27s diagnosis. Parents used proactive coping strategies to integrate complex disease management protocols into routine family life. An important source of stress was concern about the social challenges faced by their children. Participants reported positive interactions with their most involved health care providers within the metabolic clinic. However, they reported challenges associated with the health care system outside of disease-specific metabolic care, when encountering systems and providers unfamiliar with the child\u27s disease. Conclusions: The successful use of proactive coping strategies among parents of children with IMD in this study suggests the potential value of promoting positive coping and is an important direction for future study. Parents\u27 social concerns for their children were important stressors that warrant consideration by health care providers positioned to support families. Our results with respect to experiences with care highlight the important role of specialized metabolic clinics and point to a need for better coordination of the care that takes place outside the disease-specific management of IMD

Be prepared: communism and the politics of scouting in 1950s Britain

This article examines the exposure, and in some cases dismissal, of Boy Scouts who belonged or sympathised with the Young Communist League in Britain during the early 1950s. A focus on the rationale and repercussions of the organisation's approach and attitudes towards ‘Red Scouts’ found within their ‘ranks’ extends our understanding of youth movements and their often complex and conflicting ideological foundations. In particular, the post-World War Two period presented significant challenges to these spaces of youth work in terms of broader social and political change in Britain. An analysis of the politics of scouting in relation to Red Scouts questions not only the assertion that British McCarthyism was ‘silent’, but also brings young people firmly into focus as part of a more everyday politics of communism in British society
