Abstract
The electromagnetic form factors of the proton and neutron encode information on the spatial structure of their charge and magnetization distributions. While measurements of the proton are relatively straightforward, the lack of a free neutron target makes measurements of the neutron's electromagnetic structure more challenging and more sensitive to experimental or model-dependent uncertainties. Various experiments have attempted to extract the neutron form factors from scattering from the neutron in deuterium, with different techniques providing different, and sometimes large, systematic uncertainties. We present results from a novel measurement of the neutron magnetic form factor using quasielastic scattering from the mirror nuclei ^{3}H and ^{3}He, where the nuclear effects are larger than for deuterium but expected to largely cancel in the cross-section ratios. We extracted values of the neutron magnetic form factor for low-to-modest momentum transfer, 0.6

Survey of rectal cancer MRI technique and reporting tumour descriptors in the UK: a multi-centre British Society of Gastrointestinal and Abdominal Radiology (BSGAR) audit. Clin Radiol 2024; 79:117-123. [PMID: 37989667 DOI: 10.1016/j.crad.2023.10.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 10/17/2023] [Accepted: 10/21/2023] [Indexed: 11/23/2023]
Abstract
AIM To evaluate variation in magnetic resonance imaging (MRI) technique and reporting of rectal cancer staging examinations across the UK. MATERIALS AND METHODS A retrospective, multi-centre audit was undertaken of imaging protocols and information documented within consecutive MRI rectal cancer reports between March 2020 and August 2021, which were compared against American and European guidelines. Inclusion criteria included histologically proven rectal adenocarcinoma and baseline staging MRI rectum only. RESULTS Fully anonymised data from 924 MRI reports by 78 radiologists at 24 centres were evaluated. Thirty-two per cent of radiologists used template reporting, but these reports offered superior documentation of 13 out of 18 key tumour features compared to free-text reports including T-stage, relation to peritoneal reflection and mesorectal fascia (MRF), nodal status, and presence of extramural venous invasion (EMVI; p<0.027 in each). There was no significant differences in the remaining five features. Across all tumour locations, the tumour relationship to the MRF, the presence of EMVI, and the presence of tumour deposits were reported in 79.5%, 85.6%, and 44% of cases, respectively, and tumour, nodal, and distant metastatic stage documented in 94.4%, 97.7%, and 78.3%. In low rectal tumours, the relationship to the anal sphincter complex was reported in only 54.6%. CONCLUSION Considerable variation exists in rectal cancer MRI acquisition and reporting in this sample of UK centres. Inclusion of key radiological features in reports must be improved for risk stratification and treatment decisions. Template reporting is superior to free-text reporting. Routine adoption of standardised radiology practices should now be considered to improve standards to facilitate personalised precision treatment for patients to improve outcomes.

Abstract
CatSper is a voltage dependent calcium ion channel present in the principal piece of sperm tail. It plays a crucial role in sperm hyperactivated motility and so in fertilization. Extracellular loops of mouse sperm CatSper were used to develop a vaccine to achieve protection from pregnancy. These loops were inserted at one of the three hypervariable regions of Human Papilloma Virus (HPV) capsid protein (L1). Recombinant vaccines were expressed in E.coli as inclusion body (IB), purified, refolded and assembled into virus-like particles (VLP) in vitro, and adsorbed on alum. Four vaccine candidates were tested in Balb/C mice. All the constructs proved immunogenic, one showed contraceptive efficacy. This recombinant contraceptive vaccine is a non-hormonal intervention and is expected to give long-acting protection from undesired pregnancies.

Abstract
PURPOSE/OBJECTIVE(S) Neoadjuvant treatment for patients with localized pancreatic adenocarcinoma (PDAC) has improved survival duration. As survival increases, local disease control becomes even more important. We sought to understand the patterns of locoregional recurrence following total neoadjuvant therapy (TNT) and determine the impact of treatment volumes on recurrence. MATERIALS/METHODS Patients with PDAC managed with neoadjuvant chemotherapy and chemoradiation (TNT) followed by surgery who developed an isolated locoregional or simultaneously locoregional and distant recurrence were identified. Locoregional recurrences were individually contoured utilizing commercially available software. When available, original neoadjuvant dose distributions were registered to the scans on which the locoregional recurrences were contoured. Recurrences where then classified as in-field (> 95% of prescription dose), marginal (50-95% of prescription dose), or out of field (< 50% of prescription dose). Target volumes were created using four commonly utilized PDAC contouring guidelines to characterize the relationship of the local recurrence to the RT dose distribution. RESULTS Of 474 patients treated with TNT and surgery, 80 (17%) patients developed a locoregional recurrence with or without distant recurrence, visible on diagnostic imaging. Of the 80 patients, 56 (70%) had tumors in the pancreatic head; 46 (57.5%) were borderline resectable, 23 (28.8%) locally advanced, and 11 (13.6%) resectable. The most common initial neoadjuvant therapies were FOLFIRINOX (57.5%) and gemcitabine/nab-paclitaxel (18.8%). Chemoradiation included concurrent gemcitabine (47.5%) or 5-fluorouracil (26.3%). RT dose distributions were available for 38 patients; 22 (57.9%) had in-field failures, 9 (23.7%) marginal failures, and 7 (18.4%) out of field failures. Each published contouring atlas covered a relatively low percentage of recurrences, which are summarized in Table 1. Regions at particularly high likelihood of recurrence that were under covered on existing atlases included: aortic-diaphragmic junction, retro-pancreatic duodenal nodal basin, and the region to the right of the superior mesenteric artery (SMA). CONCLUSION We present the largest series (to our knowledge) of mapped locoregional recurrences for patients being treated with TNT in PDAC. These recurrences differ substantially from established atlases and highlight anatomical regions of highest priority for RT coverage. A novel visual contouring volume highlighting these regions will be presented which will strive to advance the use of RT in the TNT setting.

Abstract
Multiple introductions of tea (Camellia sinensis) to the United States since the 1850s have resulted in US tea germplasm that are currently poorly characterized. To resolve questions concerning the relatedness and regional adaptability of US tea germplasm, 32 domestic individuals were evaluated using 10 InDel markers, and compared with a background population of 30 named and registered Chinese varieties of tea. The marker data were analyzed via a neighbor-joining cladistic tree derived from Nei's genetic distance, STRUCTURE, and Discriminant Analysis of Principal Components, which revealed four genetic groups. Nineteen individuals selected from the four groups were assessed for seven leaf traits, two floral descriptors, and leaf yield, to identify plants best adapted to Florida field conditions. Our analyses compared with available historical records led us to estimate the most likely provenance of some of the US individuals, to precisely identify tea plant material and to choose most diverse accessions for breeding tea improved for adaptability, yield and quality.

Carney AE, Clarke C, Pratt WE. Administration of neuropeptide Y into the rat nucleus accumbens shell, but not core, attenuates the motivational impairment from systemic dopamine receptor antagonism by α-flupenthixol. Neurosci Lett 2023; 797:137069. [PMID: 36641044 DOI: 10.1016/j.neulet.2023.137069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 01/09/2023] [Accepted: 01/10/2023] [Indexed: 01/13/2023]
Abstract
Previous research has demonstrated that dopamine and Neuropeptide Y (NPY) promote motivated behavior, and there is evidence to suggest that they interact within neural circuitry involved in motivation. NPY and dopamine both modulate appetitive motivation towards food through direct actions in the nucleus accumbens (NAc), although how they interact in this region to promote motivation is presently unclear. In this study, we sought to further elucidate the relationship between NAc NPY and dopamine and their effects on motivated behavior. Specifically, we examined whether NAc injections of NPY might reverse behavioral deficits caused by reduced dopamine signaling due to systemic dopamine receptor antagonism. Appetitive motivation was measured using a progressive ratio-2 paradigm. Male Sprague Dawley rats were treated with systemic injections of the dopamine antagonist, α-flupenthixol or a saline vehicle. Two hours following injections, they were administered infusions of NPY (at 0, 156, or 235 pmol) into either the NAc shell (n = 12) or the NAc core (n = 10) and were placed in operant chambers. In both groups, α-flupenthixol impaired performance on the PR-2 task. NPY receptor stimulation of the NAc shell significantly increased both breakpoint and active lever presses during the PR-2 task, and dose-dependently increased responding following systemic dopamine receptor blockade. NPY did not affect appetitive motivation when injected into the NAc core. These data demonstrate that NPY in the NAc shell can improve motivational impairments that result from dopamine antagonism, and that these effects are site specific. These results also suggest that upregulation of NPY in neurodegenerative diseases may possibly buffer early motivational deficits caused by dopamine depletion in Parkinson's and Huntington's disease patients, both of which show increased NPY expression after disease onset.

Abstract
OBJECTIVE This study examines the role of MTHFR gene polymorphism (rs1801133) in women with lipedema (LIPPY) body composition parameters compared to a control group (CTRL). SUBJECTS AND METHODS We carried out a study on a sample of 45 LIPPY and 50 women as a CTRL. Body composition parameters were examined by Dual-energy X-ray Absorptiometry (DXA). A genetic test was performed for the MTHFR polymorphism (rs1801133, 677C>T) using a saliva sample for LIPPY and CTRL groups. Mann-Whitney tests evaluated statistically significant differences between four groups (carriers and non-carriers of the MTHFR polymorphism for LIPPY and CTRL groups) on anthropometric/body composition parameters to identify patterns. RESULTS LIPPY showed significantly higher (p<0.05) anthropometric parameters (weight, BMI, waist, abdominal, hip circumferences) and lower waist/hip ratio (p<0.05) compared to the CTRL group. The association between the polymorphism alleles related to the rs1801133 MTHFR gene and the body composition values LIPPY carriers (+) showed an increase in fat tissue of legs and fat region of legs percentage, arm's fat mass (g), leg's fat mass (g), and leg's lean mass (g) (p<0.05) compared to CTRL (+). Lean/fat arms and lean/fat legs were lower (p<0.05) in LIPPY (+) than in CTRL (+). In the LIPPY (+), the risk of developing the lipedema disease was 2.85 times higher (OR=2.85; p<0.05; 95% confidence interval = 0.842-8.625) with respect to LIPPY (-) and CTRL. CONCLUSIONS The presence or absence of MTHFR polymorphism offers predictive parameters that could better characterize women with lipedema based on the association between body composition and MTHFR presence.

Abstract
Background 65,000 people live with dementia in Ireland, many have co-existing or emerging mental health illnesses and non-cognitive symptoms. During the COVID-19 pandemic there was a need to provide innovative solutions to service provision. As Medicine for the Elderly (MEDEL) and Psychiatry of Later Life (PLL) were established stand-alone services, there was no formalised working relationship, resulting in an overlap of cases and disparity in service provision. Methods A description of three cases to illustrate the joint working interface with MEDEL and PLL. These cases highlight their complex care needs and the speciality input required by both services within a shared catchment area. The age range was 78-88 years. All presented with at least two medical co-morbidities, including vascular risk factors and delirium. Each had at least one mental health illness including new onset psychotic and mood disorders. Sharing of resources including diagnostic services, nursing, medical, occupational therapy, physiotherapy and social work facilitated cost effective holistic care. Results Given the existing structures of MEDEL and PLL, it was possible to link with community partners attached to each service, allowing domiciliary visits for crisis intervention and best use of expertise from both disciplines. This resulted in the provision of timely patient centred care, reduced polypharmacy through a unified pharmacological approach, enhanced communication, shared learning and cost effectiveness. Care that is in the right place at the right time, in line with Sláinte Care, allowed timely access to diagnostics, improved care outcomes and a cohesive response. Conclusion This cohort present with complex care needs. An integrated approach enables patients to receive holistic care without duplication of resources or disparity of treatment and care options. Going forward this should involve a fully integrated memory service, with shared governance.

Abstract
We report a precise measurement of the parity-violating (PV) asymmetry A_{PV} in the elastic scattering of longitudinally polarized electrons from ^{48}Ca. We measure A_{PV}=2668±106(stat)±40(syst) parts per billion, leading to an extraction of the neutral weak form factor F_{W}(q=0.8733 fm^{-1})=0.1304±0.0052(stat)±0.0020(syst) and the charge minus the weak form factor F_{ch}-F_{W}=0.0277±0.0055. The resulting neutron skin thickness R_{n}-R_{p}=0.121±0.026(exp)±0.024(model) fm is relatively thin yet consistent with many model calculations. The combined CREX and PREX results will have implications for future energy density functional calculations and on the density dependence of the symmetry energy of nuclear matter.

Abstract
We report precision determinations of the beam-normal single spin asymmetries (A_{n}) in the elastic scattering of 0.95 and 2.18 GeV electrons off ^{12}C, ^{40}Ca, ^{48}Ca, and ^{208}Pb at very forward angles where the most detailed theoretical calculations have been performed. The first measurements of A_{n} for ^{40}Ca and ^{48}Ca are found to be similar to that of ^{12}C, consistent with expectations and thus demonstrating the validity of theoretical calculations for nuclei with Z≤20. We also report A_{n} for ^{208}Pb at two new momentum transfers (Q^{2}) extending the previous measurement. Our new data confirm the surprising result previously reported, with all three data points showing significant disagreement with the results from the Z≤20 nuclei. These data confirm our basic understanding of the underlying dynamics that govern A_{n} for nuclei containing ≲50 nucleons, but point to the need for further investigation to understand the unusual A_{n} behavior discovered for scattering off ^{208}Pb.

Abstract
The mass of the W boson, a mediator of the weak force between elementary particles, is tightly constrained by the symmetries of the standard model of particle physics. The Higgs boson was the last missing component of the model. After observation of the Higgs boson, a measurement of the W boson mass provides a stringent test of the model. We measure the W boson mass, MW, using data corresponding to 8.8 inverse femtobarns of integrated luminosity collected in proton-antiproton collisions at a 1.96 tera-electron volt center-of-mass energy with the CDF II detector at the Fermilab Tevatron collider. A sample of approximately 4 million W boson candidates is used to obtain [Formula: see text], the precision of which exceeds that of all previous measurements combined (stat, statistical uncertainty; syst, systematic uncertainty; MeV, mega-electron volts; c, speed of light in a vacuum). This measurement is in significant tension with the standard model expectation.

Abstract
OBJECTIVES The objective of this study was to understand the variables or study habits that inform study in undergraduate and postgraduate students attending Trinity College Dublin. METHODS A descriptive, cross-sectional anonymous online survey was used to gather data to explore student study habits. Survey 1 was completed by participants in April 2019 and survey 2 was completed by participants in April 2020, during the COVID-19 restrictions. RESULTS A total of 1557 participants completed survey 1 in 2019, and 1793 participants completed survey 2 in 2020. In both surveys a majority reported using caffeine, library study, sleep pattern adjustment and excercise to aid academic performance. Survey 2 participants reported COVID-19 resulted in increased difficulty studying (91%). In particular loss of structure and routine was negatively impacted by the pandemic (92%), and increased feelings of stress were reported (75%). CONCLUSIONS Our study suggests a potential role of the college environment as a target for the implementation of interventions to promote student learning, healthy study habits and well-being. The global pandemic has resulted in additional challenging demands for universities to serve an essential role in supporting college students study habits.

Abstract
We report a precision measurement of the parity-violating asymmetry A_{PV} in the elastic scattering of longitudinally polarized electrons from ^{208}Pb. We measure A_{PV}=550±16(stat)±8(syst) parts per billion, leading to an extraction of the neutral weak form factor F_{W}(Q^{2}=0.00616 GeV^{2})=0.368±0.013. Combined with our previous measurement, the extracted neutron skin thickness is R_{n}-R_{p}=0.283±0.071 fm. The result also yields the first significant direct measurement of the interior weak density of ^{208}Pb: ρ_{W}^{0}=-0.0796±0.0036(exp)±0.0013(theo) fm^{-3} leading to the interior baryon density ρ_{b}^{0}=0.1480±0.0036(exp)±0.0013(theo) fm^{-3}. The measurement accurately constrains the density dependence of the symmetry energy of nuclear matter near saturation density, with implications for the size and composition of neutron stars.

Abstract
BACKGROUND MicroRNAs [miRNAs] are cell-specific small non-coding RNAs that can regulate gene expression and have been implicated in inflammatory bowel disease [IBD] pathogenesis. Here we define the cell-specific miRNA profiles and investigate its biomarker potential in IBD. METHODS In a two-stage prospective multi-centre case control study, next generation sequencing was performed on a discovery cohort of immunomagnetically separated leukocytes from 32 patients (nine Crohn's disease [CD], 14 ulcerative colitis [UC], eight healthy controls) and differentially expressed signals were validated in whole blood in 294 patients [97 UC, 98 CD, 98 non-IBD, 1 IBDU] using quantitative PCR. Correlations were analysed with phenotype, including need for early treatment escalation as a marker of progressive disease using Cox proportional hazards. RESULTS In stage 1, each leukocyte subset [CD4+ and CD8+ T-cells and CD14+ monocytes] was analysed in IBD and controls. Three specific miRNAs differentiated IBD from controls in CD4+ T-cells, including miR-1307-3p [p = 0.01], miR-3615 [p = 0.02] and miR-4792 [p = 0.01]. In the extension cohort, in stage 2, miR-1307-3p was able to predict disease progression in IBD (hazard ratio [HR] 1.98, interquartile range [IQR]: 1.20-3.27; logrank p = 1.80 × 10-3), in particular CD [HR 2.81; IQR: 1.11-3.53, p = 6.50 × 10-4]. Using blood-based multimarker miRNA models, the estimated chance of escalation in CD was 83% if two or more criteria were met and 90% for UC if three or more criteria are met. INTERPRETATION We have identified and validated unique CD4+ T-cell miRNAs that are differentially regulated in IBD. These miRNAs may be able to predict treatment escalation and have the potential for clinical translation; further prospective evaluation is now indicated.

Abstract
The mental health of third-level students is of major societal concern with the gap between the demand for services and supports offered at crisis level. In Ireland, similar to elsewhere, colleges have responded to this need in vastly differing ways, with student counselling services available to all institutions, and student health departments and sessional psychiatry in some of the larger institutions, with none operating as a single multidisciplinary service. There is an increasing recognition for a more systematised approach, with the establishment of International Networks, Charters and Frameworks. These advocate for a whole institutional approach to student mental health, in addition to the development of an integrated system of supports with effective pathways to appropriate care. This paper, by members of the Youth and Student Special Interest Group of the College of Psychiatrists of Ireland, contextualises student mental health currently and describes future directions for this emerging field. It is a call to action to develop a structure that supports the needs of students with mental health problems across the full range of the spectrum from mild to severe.

Abstract
BACKGROUND Pork consumption, in particular fresh/lean-pork consumption, provides protein and other essential micronutrients that older adults need daily and may hold the potential to prevent functional limitations resulting from sub-optimal nutrition. AIM Assess fresh/lean-pork intake in relation to functional limitations among older adults in the USA. METHODS Individual-level data came from the National Health and Nutrition Examination Survey (NHANES) 2005-2016 waves. Nineteen validated questions assessed five functional limitation domains: activities of daily living (ADLs); instrumental activities of daily living (IADLs); leisure and social activities (LSAs); lower extremity mobility (LEM); and general physical activities (GPAs). Logistic regressions were performed to examine pork, fresh-pork and fresh lean-pork intake in relation to functional limitations among NHANES older adults (n = 6135). RESULTS Approximately 21, 18 and 16% of older adults consumed pork, fresh pork and fresh lean pork, respectively. An increase in pork consumption by 1 oz-equivalent/day was associated with a reduced odds of ADLs by 12%, IADLs by 10% and any functional limitation by 7%. An increase in fresh-pork consumption by 1 oz-equivalent/day was associated with a reduced odds of ADLs by 13%, IADLs by 10%, GPAs by 8%, and any functional limitation by 8%. Similar effects were found for fresh lean-pork consumption on ADLs, IADLs, GPAs and any functional limitation. CONCLUSION This study found some preliminary evidence linking fresh/lean-pork consumption to a reduced risk of functional limitations. Future studies with longitudinal/experimental designs are warranted to examine the influence of fresh/lean-pork consumption on functional limitations.

Abstract
Beef is a key component in the American diet. This study assessed fresh and fresh lean beef intake in relation to functional limitations among U.S. older adults 65 years and older. Logistic regressions were performed on individual-level 24-hour dietary recall and health indicator data (N=6,135) retrieved from 2005–2016 National Health and Nutrition Examination Survey. Approximately 51%, 14%, and 9% of older adults consumed beef, fresh beef, and fresh lean beef, respectively. Daily increase in fresh beef consumption by 1 ounce-equivalent was associated with a reduction in the odds of lower extremity mobility limitation (LEM) by 16% (95% confidence interval=4%–27%), general physical activities limitation by 13% (1%–24%), and any functional limitation by 14% (2%–24%). Daily increase in fresh lean beef consumption by 1 ounce-equivalent was associated with a reduction in the odds of LEM by 22% (7%–34%) and any functional limitation by 15% (1%–28%). No association with activities of daily living, instrumental activities of daily living, or leisure and social activities limitations was identified. In conclusion, preliminary evidence links fresh and fresh lean beef consumption to reduced functional limitation risk. Older beef consumers are encouraged to modestly increase their intakes of fresh and lean beef, rather than total beef, to maximize attributes of functional health associated with beef consumption while concurrently avoiding additional saturated fat and sodium intake. Limitations of this study include measurement errors and cross-sectional study design. Future studies with longitudinal/experimental design are warranted to examine the influence of fresh/lean beef consumption on functional limitations among older adults.
