RESUMO
Wild capture fisheries are of economic and social importance, providing a primary source of protein to people globally. There is a broad research base on the environmental impacts of fishing gears and processing methods yet, the impact on the global CO2 budget is less well studied. Evaluating the risk that wild capture fisheries pose to ecosystem health is vital to sustainably managing fishing practices to meet increasing global nutritional needs and reverse declines in marine biodiversity. At the same time meeting net-zero ambitions by reducing direct and indirect GHG emissions is vital. Ecological risk assessments, trait-based assessments, and vulnerability assessments have long supported fisheries management systems globally but do not yet provide any representation regarding the impacts that fishing gears have on the ability of the habitat to capture and store carbon. Considering the importance of accessibility and transparency in approaches necessary for fisheries sustainability certifications, this paper describes a method to integrate habitat carbon capacity attributes into the Marine Stewardship Council (MSC) Consequence and Spatial Analysis (CSA) framework. Applying the CSA carbon extension developed herein produces different CSA risk scores compared to the MSC CSA that does not account for carbon. This has potential consequences for certification schemes as carbon becomes more important in the fisheries sustainability conversation. The CSA carbon extension tool developed here is an important first step in incorporating carbon indicators into evaluations of fisheries that consider fishery carbon impacts.

There are few formal publications in Australia relating to Victorian-era dentures and reliable evidence relating to their contemporaneous design, ownership and type is almost non-existent. Archeologists have reported only ten denture units retrieved from eight individuals interred in 19th century Australian cemeteries. A salvage excavation in 2001 at the North Brisbane Burial Grounds (NBBG, 1843-1875) uncovered, inter alia, an assemblage of two metal- and two vulcanite-based dentures. The names of the owners, the records of the dental practitioners and allied contextual information have been lost. This report is the first detailed analysis in Australia of 19th century dentures. It presents an investigation into the composition and underpinning laboratory technology within this quartette of NBBG artifacts, which represent half the known, and the only two alloy-based, dentures retrieved from 19th century cemeteries throughout Australia. The data within is a compilation of and extensive literature review, historical research methods, macroscopic inspection, scanning electron microscopy and energy dispersive x-ray spectroscopy. The results provide insight into dental practice and affiliated technologies in Victorian-era Brisbane.

Current policy in the UK recommends that men bank sperm prior to cancer treatment, but very few return to use it for reproductive purposes or agree to elective disposal even when their fertility recovers and their families are complete. We assessed the demographic, medical and psychological variables that influence the decision to dispose by contacting men (n = 499) who banked sperm more than five years previously, and asked them to complete questionnaires about their views on sperm banking, fertility and disposal. From 193 responses (38.7% response rate), 19 men (9.8%) requested disposal within four months of completing the questionnaire. Compared with men who wanted their sperm to remain in storage, they were significantly more confident that their fertility had recovered (OR = 1.78, 95% CI = 1.05-3.03, p = 0.034), saw fertility monitoring (semen analysis) as less important (OR = 0.61, 95% CI = 0.39-0.94, p = 0.026), held more positive attitudes to disposal (OR = 5.71, 95% CI = 2.89-11.27, p < 0.001), were more likely to have experienced adverse treatment side-effects (OR = 4.37, CI = 1.61-11.85, p = 0.004) and had less desire for children in the future (OR = 0.41, 95% CI = 0.26-0.64, p < 0.001). Information about men's reasons to dispose of banked sperm may be helpful in devising new strategies to encourage men to engage with sperm banking clinics and make timely decisions about the fate of their samples.

Abstract Long-term storage of banked sperm, especially when it is not needed, for reproductive purposes, is costly and poses practical problems for sperm banks. For sperm banks to function efficiently, men must understand the implications of unnecessary storage, and make timely decisions about disposal of their own samples. Men who bank sperm prior to cancer treatment are routinely offered follow-up consultations to test their fertility, update consent and, where necessary, expedite referral for Assisted Conception. Yet sperm banks report that men do not respond to letters, suggesting samples are stored needlessly. We conducted semi-structured interviews with six men with a history of not responding to letters, to document reasons for non-response. Interviews were transcribed and analysed using Interpretive Phenomenological Analysis. Men's reasons for not responding are a complex interplay between past, present and future perspectives. In terms of their past, information is important on diagnosis, because men must understand that fertility can change after treatment. Present and future concerns focus on fears of being told fertility has not recovered and being pressured to dispose of banked sperm. The challenge is to devise invitation letters that address men's concerns while offering them tangible benefits and peace of mind.

Peace, both personal and global, resides in understanding. Verbatim theatre is introduced as a vehicle for translating research findings to promote understanding and thereby, promote health. By shifting our translation lens from "bench to bedside" to "field to forum," new opportunities arise for moving nursing research-findings to an engaged audience. Stories from Pearl Harbor and Hiroshima survivors were woven into the verbatim performance, With Their Voices Raised. Analysis of audience members' reflections after the performance suggests that verbatim theatre created a connection based in openness, engagement, and trust that informed understanding and raised awareness about peace processes.

We have previously shown that the cell death-promoting protein Bcl-2-interacting mediator of cell death (Bim) is ubiquitinated and degraded following a neuroprotection-conferring episode of brief ischemia (preconditioning). Here, we identify the E3 ligase that ubiquitinates Bim in this model, using a proteomics approach. Using phosphorylated GST-Bim as bait, we precipitated and identified by mass spectrometry tripartite motif protein 2 (TRIM2), a RING (really interesting new gene) domain-containing protein. The reaction between TRIM2 and Bim was confirmed using co-immunoprecipitation followed by immunoblotting. We show that TRIM2 binds to Bim when it is phosphorylated by p42/p44 MAPK but does not interact with a nonphosphorylatable Bim mutant (3ABim). 12-O-tetradecanoylphorbol-13-acetate activation of p42/p44 MAPK drives Bim ubiquitination in mouse embryonic fibroblast cells and is associated with an increased interaction between TRIM2 and Bim. One hour following preconditioning ischemia, the binding of Bim to TRIM2 increased, consistent with the time window of enhanced Bim degradation. Blocking p42/p44 MAPK activation following preconditioning ischemia with U0126 or using the nonphosphorylatable 3ABim reduced the binding between Bim and TRIM2. Immunodepletion of TRIM2 from cell lysates prepared from preconditioned cells reduced Bim ubiquitination. Finally, suppression of TRIM2 expression, using lentivirus transduction of shRNAmir, stabilized Bim protein levels and blocked neuroprotection observed in rapid ischemic tolerance. Taken together, these data support a role for TRIM2 in mediating the p42/p44 MAPK-dependent ubiquitination of Bim in rapid ischemic tolerance.

The aim of the study was to assess dimensions of the patient-clinician relationship in relation to adherence with antiretroviral medication in a sample of HIV patients. This was a correlational evaluation, using a cross-sectional design. Thirty-eight HIV patients in two UK HIV units provided complete data. Analysis suggested that the elements of the patient-clinician relationship contributing to adherence with medication were the patient perception of being valued and respected by the clinician, the patients' ability to initiate discussions about the treatment, empowerment and level of trust placed in the nurse. The latter, and the time since starting antiretroviral treatment, were the only two variables that could predict adherence in a regression model, explaining 41% of the variance in adherence. Building trusted relationships with the patients and investing in educational and communication techniques to improve the therapeutic relationship could strongly contribute to HIV patients to maintaining high adherence rates.
