Abstract
Objective We sought to create and characterize a mouse model of the inflammatory, cerebral demyelinating phenotype of X-linked adrenoleukodystrophy (ALD) that would facilitate the study of disease pathogenesis and therapy development. We also sought to cross-validate potential therapeutic targets such as fibrin, oxidative stress, and the NLRP3 inflammasome, in post-mortem human and murine brain tissues. Background ALD is caused by mutations in the gene ABCD1 encoding a peroxisomal transporter. More than half of males with an ABCD1 mutation develop the cerebral phenotype (cALD). Incomplete penetrance and absence of a genotype-phenotype correlation imply a role for environmental triggers. Mechanistic studies have been limited by the absence of a cALD phenotype in the Abcd1-null mouse. Methods We generated a cALD phenotype in 8-week-old, male Abcd1-null mice by deploying a two-hit method that combines cuprizone (CPZ) and experimental autoimmune encephalomyelitis (EAE) models. We employed in vivo MRI and post-mortem immunohistochemistry to evaluate myelin loss, astrogliosis, blood-brain barrier (BBB) disruption, immune cell infiltration, fibrin deposition, oxidative stress, and Nlrp3 inflammasome activation in mice. We used bead-based immunoassay and immunohistochemistry to evaluate IL-18 in CSF and post-mortem human cALD brain tissue. Results MRI studies revealed T2 hyperintensities and post-gadolinium enhancement in the medial corpus callosum of cALD mice, similar to human cALD lesions. Both human and mouse cALD lesions shared common histologic features of myelin phagocytosis, myelin loss, abundant microglial activation, T and B-cell infiltration, and astrogliosis. Compared to wild-type controls, Abcd1-null mice had more severe cerebral inflammation, demyelination, fibrin deposition, oxidative stress, and IL-18 activation. IL-18 immunoreactivity co-localized with macrophages/microglia in the perivascular region of both human and mouse brain tissue. Interpretation This novel mouse model of cALD suggests loss of Abcd1 function predisposes to more severe cerebral inflammation, oxidative stress, fibrin deposition, and Nlrp3 pathway activation, which parallels the findings seen in humans with cALD. We expect this model to enable long-sought investigations into cALD mechanisms and accelerate development of candidate therapies for lesion prevention, cessation, and remyelination.

Abstract
PURPOSE This paper presents an assessment of a low-cost organ perfusion machine designed for use in research settings. The machine is modular and versatile in nature, built on a robotic operating system (ROS2) pipeline allowing for the addition of specific sensors for different research applications. Here we present the system and the development stages to achieve viability of the perfused organ. METHODS The machine's perfusion efficacy was assessed by monitoring the distribution of perfusate in livers using methylene blue dye. Functionality was evaluated by measuring bile production after 90 min of normothermic perfusion, while viability was examined using aspartate transaminase assays to monitor cell damage throughout the perfusion. Additionally, the output of the pressure, flow, temperature, and oxygen sensors was monitored and recorded to track the health of the organ during perfusion and assess the system's capability of maintaining the quality of data over time. RESULTS The results show the system is capable of successfully perfusing porcine livers for up to three hours. Functionality and viability assessments show no deterioration of liver cells once normothermic perfusion had occurred and bile production was within normal limits of approximately 26 ml in 90 min showing viability. CONCLUSION The developed low-cost perfusion system presented here has been shown to keep porcine livers viable and functional ex vivo. Additionally, the system is capable of easily incorporating several sensors into its framework and simultaneously monitor and record them during perfusion. The work promotes further exploration of the system in different research domains.

Abstract
Background In the 1970s, Jack Flanagan developed the first Geriatric Day Hospital (GDH) in Ireland. Since, the GDH model of care has evolved to accommodate for the growing demands of our ageing population. Before the COVID-19 pandemic, the operational scope of our GDH was extended to allow for the rapid medical and multidisciplinary assessment and follow-up of older patients. During the pandemic, the GDH did not suspend operations and remained open as a COVID-negative ambulatory pathway. We evaluated the activity of this GDH service. Methods Retrospective Service Evaluation Approval was granted by our Research & Innovation Office (Reference: 7419). Pseudonymised data corresponding to all GDH attendances between January 2017 and December 2021 were retrieved from the hospital electronic records. Yearly trends in proportions were tested with the Chi-square for trend statistic. Trends in monthly attendances were assessed via Statistical Process Control (SPC) charts with three-sigma limits. Statistical significance was set at p<0.05. Results There were 27,278 attendances of patients aged 65 and over to the GDH over the 5-year period (6,362, 5,978, 6,115, 4,306, and 4,517, respectively). Mean age was 82 every year. Of the 7,813 new episodes, yearly proportions referred directly by primary care teams were 10.4%, 29.5%, 38.6%, 24.5%, and 16.3% (p<0.001). SPC charts showed that Apr-May 2020 and Jan-Feb 2021 had significantly lower numbers of review attendances (50-59 and 146-142, respectively, average 324 p/m). However, new appointments did not significantly decline (average 130 p/m). Of the 7,813 new episodes, 2,595 (33.2%) were seen by Physiotherapy, and 1,860 (23.8%) by Occupational Therapy. Conclusion Our GDH saw a sustained number of new attendances and demonstrated increased community availability during the unprecedented COVID-19 crisis, especially during the first wave of the pandemic when hospital access was most affected. A rapid access GDH model can facilitate integrated care at times of crisis to promote ageing in place.

Abstract
Abstract
Background
Neuroimaging is an increasingly important tool dementia work-up. Subtype diagnosis helps predict the course of the disease, aiding prognostication and management. Amyloid-beta peptide is intrinsic to the pathogenesis of Alzheimer’s disease (AD), forming characteristic neuritic plaques which can be imaged in vivo on positron emission tomography (PET) scans. NICE recommendations advise use of PET imaging if dementia sub-type diagnosis is unclear and AD is suspected. We sought to establish the referral patterns for FDG-PET brain scans for patients aged 60 and over in a university hospital and to establish whether this imaging modality contributed to a change in diagnosis or treatment.
Methods
Requests for FDG-PET CT brain from 2019 – 2022 were retrospectively reviewed. Information was obtained from clinical notes and patient information software. Patient demographics, indication for scan, source of referral and whether imaging results led to a change in diagnosis or treatment was recorded.
Results
A total of 32 patients were reviewed, with a mean age of 65 years (13 females; 41%). We further analysed the 25 who were aged over 60; this subgroup had a mean age of 70 (9 females; 36%). All 25 patients were appropriately referred to assess for dementia subtype. A revision in diagnosis based on PET imaging was made in 17 (68%) cases. In 9 (30%) cases, results prompted change in dementia-specific pharmacological treatment, including donepezil and memantine. A further 6 (24%) had pharmacological treatment for non-cognitive symptoms of dementia adjusted, such as anti-depressants or anti-psychotics. The majority of referrals had come from neurologists (n = 15; 60%) rather than geriatricians (n = 10; 40%). The final diagnosis was AD in 12 cases (48%) and fronto-temporal dementia in 3 cases (12%).
Conclusion
PET scans are a useful functional imaging modality which can help to differentiate dementia subtypes and influence management.

Abstract
BACKGROUND Cancer survivors over the age of 65 have unique needs due to the higher prevalence of functional and cognitive impairment, comorbidities, geriatric syndromes, and greater need for social support after chemotherapy. In this study, we will evaluate whether a Geriatric Evaluation and Management-Survivorship (GEMS) intervention improves functional outcomes important to older cancer survivors following chemotherapy. METHODS A cluster-randomized trial will be conducted in approximately 30 community oncology practices affiliated with the University of Rochester Cancer Center (URCC) National Cancer Institute Community Oncology Research Program (NCORP) Research Base. Participating sites will be randomized to the GEMS intervention, which includes Advanced Practice Practitioner (APP)-directed geriatric evaluation and management (GEM), and Survivorship Health Education (SHE) that is combined with Exercise for Cancer Patients (EXCAP©®), or usual care. Cancer survivors will be recruited from community oncology practices (of participating oncology physicians and APPs) after the enrolled clinicians have consented and completed a baseline survey. We will enroll 780 cancer survivors aged 65 years and older who have completed curative-intent chemotherapy for a solid tumor malignancy within four weeks of study enrollment. Cancer survivors will be asked to choose one caregiver to also participate for a total up to 780 caregivers. The primary aim is to compare the effectiveness of GEMS for improving patient-reported physical function at six months. The secondary aim is to compare effectiveness of GEMS for improving patient-reported cognitive function at six months. Tertiary aims include comparing the effectiveness of GEMS for improving: 1) Patient-reported physical function at twelve months; 2) objectively assessed physical function at six and twelve months; and 3) patient-reported cognitive function at twelve months and objectively assessed cognitive function at six and twelve months. Exploratory health care aims include: 1) Survivor satisfaction with care, 2) APP communication with primary care physicians (PCPs), 3) completion of referral appointments, and 4) hospitalizations at six and twelve months. Exploratory caregiver aims include: 1) Caregiver distress; 2) caregiver quality of life; 3) caregiver burden; and 4) satisfaction with patient care at six and twelve months. DISCUSSION If successful, GEMS would be an option for a standardized APP-led survivorship care intervention. TRIAL REGISTRATION ClinicalTrials.govNCT05006482, registered on August 9, 2021.

Abstract
This paper presents a novel, low cost, organ perfusion machine designed for use in research. The modular and versatile nature of the system allows for additional sensing equipment to be added or adapted for specific use. Here we introduce the system and present its preliminary evaluation by assessing its ability to maintain a predetermined input pressure. A proportional-integral-derivative (PID) controller was implemented and tested on a porcine liver to maintain input pressure to the hepatic artery and compared to bench tests. The results confirmed the effectiveness of the controller for maintaining input through the hepatic artery (HA) in a timely manner. Clinical Relevance-Machine Perfusion (MP) is proving to be an invaluable adjunct in clinical practice. With its ongoing success in the transplant arena, we propose MP for use in research. A cost-effective, versatile system that can be modified for specific research use to test new pharmacological therapies, imaging techniques or develop simulation training would be beneficial.

Abstract
Abstract
Background
Older adults with acute fractures often have suboptimal pain control, in particular those with cognitive impairment. Effective pain management improves rehabilitation engagement and earlier discharge from acute care. Our study aimed to evaluate pain management of older adults with acute fracture admitted under an orthopaedic service in a tertiary hospital.
Methods
Prospective review of patients over 65 years with an acute fracture admitted under an orthopaedic service. Review of chart, medication prescription and pain status. Data included type of fracture, comorbidities, cognitive status and analgesia prescribed. Data analysed using Excel.
Results
40 inpatients included. Median age 82 years (range 65-93 years), 70% female. 53% had cognitive impairment, ranging from mild to severe dementia. 75% had >5 regular medications pre-admission. 80% had >5 comorbidities.
Two-thirds (73%) had an acute hip fracture. Most (80%) inpatients had a surgical intervention, the remaining were managed conservatively.
Analgesia prescriptions included paracetamol for almost all patients (95%), non-steroidal anti-inflammatory drugs for 3 (8%) and regular opioids in only 3 (8%).
43% of patients reported pain at time of data collection. 13% had analgesia changed in the 24 hours beforehand. Pain adversely affected function in 205 and mobility in 28%.
2 patients were unable to verbalise pain however no pain scales or visual assessments were used.
Documentation of pain assessment was best by nurses (100%) followed by doctors (60%) and allied health professionals (40%).
Conclusion
Older adults with acute fracture are often multimorbid with cognitive impairment. This patient population are often untreated for pain with suboptimal pain assessment and analgesia review or prescriptions. Consequently we developed a pain policy for use on our orthopaedic service as a guide for effective pain assessment and management for older adults with acute fracture.

Hip fractures are a significant cause of morbidity and mortality amongst older adults. The Irish Hip Fracture Database Standard 5 requires that all patients with hip fracture have a bone health assessment completed; most are commenced on bone protection therapy (BPT) to reduce future fractures. Communication to general practitioners (GPs) regarding long-term BPT is often incomplete and challenging to improve. We aimed to upgrade this communication process at discharge.
Methods
Initial audit was conducted assessing documentation of BPT after hip fracture in discharge letters to GPs. Subsequently we created a detailed BPT template for discharge letters containing clear information for GPs regarding medication initiation and advice for ongoing management. The template was introduced and doctors were educated on its use. We then re-audited discharge letters following this intervention. Patients included were over 60 years old with hip fracture. Patients deemed clinically unsuitable for BPT were excluded.
Results
Ninety discharge letters were reviewed, 45 at initial audit and another 45 after introducing the BPT template. Mean age was 80 years old, 66 (73%) were female. In the first audit cycle, 28/45 discharge letters (62%) briefly specified BPT. On repeating the audit cycle (following introduction of the discharge letter template) all 45/45 discharge letters (100%) clearly specified BPT. Most letters (41/45; 91%) included the detailed BPT template. Following this intervention all doctors reported increased awareness and understanding of BPT, and satisfaction with template use in discharge letters.
Conclusion
Effective implementation of a discharge letter template significantly improved communication to GPs regarding BPT following hip fracture.

Abstract
Abstract
Background
Orthostatic hypotension, characterized by delayed blood pressure recovery (DBPR) after standing, is a risk factor for falls but the longitudinal relationship with fracture is not yet known. The aim of this study was to examine the prospective risk of fracture associated with DBPR.
Methods
This study, embedded within the Irish Longitudinal Study on Ageing (TILDA), examined prospective risk of fracture (hip, wrist or vertebral) associated with DBPR at 8-year follow-up in a population-representative sample of more than 3,000 (54% female) community-dwelling older people. Orthostatic blood pressure (BP) was measured using a finometer during active stand at TILDA Wave 1. DBPR was defined as systolic BP ≤ 20 mmHg lower and/or diastolic BP ≤ 10 mmHg from baseline value at 30, 60 and 90 seconds after standing. Participants with a fracture reported at any of Waves 2–5 were defined as having ‘Incident Fracture’. Logistic regression models were used to estimate odds ratios (ORs) for the association between DBPR and incident fracture.
Results
Seven percent (212/3117) of participants sustained a fracture during follow-up. DBPR at 30 seconds was a significant predictor of any fracture [OR 1.80, 95% confidence interval (CI) 1.28–2.53] and hip fracture (OR 4.44, 95% CI 2.03–9.71) in fully adjusted models. DBPR at 30 seconds did not predict wrist or vertebral fracture. DBPR at 60 seconds also predicted any fracture (OR 1.74, 95% CI 1.19–2.54) and hip fracture (OR 4.66, 95% CI 2.12–10.26) whereas DBPR at 90 seconds predicted any (OR 1.99, 95% CI 1.38–2.87), wrist (OR 1.87, 95% CI 1.19–2.95), and hip fracture (OR 3.39, 95% CI 1.45–7.93) in fully adjusted models.
Conclusion
Delayed BP recovery independently predicts fracture in community-dwelling older people, is potentially modifiable, and can be measured in an ambulatory setting. Given the morbidity and mortality associated with fractures, identification of such risk factors is crucial in order to inform preventative strategies.

Abstract
Background The COVID-19 pandemic and the associated economic recession has increased parental psychosocial stress and mental health challenges. This has adversely impacted child development and wellbeing, particularly for children from priority populations (culturally and linguistically diverse (CALD) and rural/regional communities) who are at an already increased risk of health inequality. The increased mental health and psychosocial needs were compounded by the closure of in-person preventive and health promotion programs resulting in health organisations embracing technology and online services. Watch Me Grow- Electronic (WMG-E) – developmental surveillance platform- exemplifies one such service. WMG-E was developed to monitor child development and guide parents towards more detailed assessments when risk is identified. This Randomised Controlled Trial (RCT) aims to expand WMG-E as a digital navigation tool by also incorporating parents’ mental health and psychosocial needs. Children and families needing additional assessments and supports will be electronically directed to relevant resources in the ‘care-as-usual’ group. In contrast, the intervention group will receive continuity of care, with additional in-person assessment and ‘warm hand over’ by a ‘service navigator’ to ensure their needs are met. Methods Using an RCT we will determine: (1) parental engagement with developmental surveillance; (2) access to services for those with mental health and social care needs; and (3) uptake of service recommendations. Three hundred parents/carers of children aged 6 months to 3 years (recruited from a culturally diverse, or rural/regional site) will be randomly allocated to the ‘care-as-usual’ or ‘intervention’ group. A mixed methods implementation evaluation will be completed, with semi-structured interviews to ascertain the acceptability, feasibility and impact of the WMG-E platform and service navigator. Conclusions Using WMG-E is expected to: normalise and de-stigmatise mental health and psychosocial screening; increase parental engagement and service use; and result in the early identification and management of child developmental needs, parental mental health, and family psychosocial needs. If effective, digital solutions such as WMG-E to engage and empower parents alongside a service navigator for vulnerable families needing additional support, will have significant practice and policy implications in the pandemic/post pandemic period. Trial registration The trial (Protocol No. 1.0, Version 3.1) was registered with ANZCTR (registration number: ACTRN12621000766819) on July 21st, 2021 and reporting of the trial results will be according to recommendations in the CONSORT Statement.

Abstract
Aging is the major risk factor for several neurodegenerative diseases, including Alzheimer's disease (AD). However, the mechanisms by which aging contributes to neurodegeneration remain elusive. The nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is a transcription factor that regulates expression of a vast number of genes by binding to the antioxidant response element. Nrf2 levels decrease as a function of age, and reduced Nrf2 levels have been reported in postmortem human brains and animal models of AD. Nevertheless, it is still unknown whether Nrf2 plays a role in the cognitive deficits associated with AD. To address this question, we used a genetic approach to remove the Nrf2 gene from APP/PS1 mice, a widely used animal model of AD. We found that the lack of Nrf2 significantly exacerbates cognitive deficits in APP/PS1, without altering gross motor function. Specifically, we found an exacerbation of deficits in spatial learning and memory, as well as in working and associative memory. Different brain regions control these behavioral tests, indicating that the lack of Nrf2 has a global effect on brain function. The changes in cognition were linked to an increase in Aβ and interferon-gamma (IFNγ) levels, and microgliosis. The changes in IFNγ levels are noteworthy as previously published evidence indicates that IFNγ can increase microglia activation and induce Aβ production. Our data suggest a clear link between Nrf2 and AD-mediated cognitive decline and further strengthen the connection between Nrf2 and AD.

Abstract
Abstract
Streptococcus pneumoniae is a major cause of disease and death worldwide, particularly in neonatal, elderly, and immunodeficient patients. We examined the impact of the gut microbiota on lung disease (known as the gut-lung axis) using traditional immunocompetent as well as novel immunocompromised mouse models of S. pneumoniae lung infection. Adaptive immunity against S. pneumoniae depends largely on T-independent II (TI-II) antibodies against the bacterial polysaccharide capsule. We found that colonization with the gut commensal Segmented Filamentous Bacteria (SFB) increased anti-S. pneumoniae TI-II antibodies, but did not further enhance protection against S. pneumoniae in wild type mice. Indeed, basal B cell activity in the absence of SFB colonization was sufficient to provide essential protection against S. pneumoniae. However, in adaptive immune-compromised mice, we demonstrated a gut-lung axis of communication, as SFB colonization modulated the innate immune response to enhance protection against S. pneumoniae lung infection. Neutrophils are important first responders during pneumonia, but proper neutrophil resolution is essential to prevent excessive tissue damage. We found that SFB colonization led to more efficient clearance of lung neutrophils at 3 days after infection, which correlated with a decrease in CD47, a transmembrane glycoprotein that inhibits clearance of apoptotic cells, on lung neutrophils in SFB+ immunocompromised mice. This accompanied a shift in lung neutrophils from CD18hiCD62L−/lo inflammatory neutrophils to CD18−/loCD62Lhi pro-resolution neutrophils. These data demonstrate that a gut commensal modulates the innate immune response to enhance protection against a lung infection.

Background
The aim was to carry out phase 4 international field-testing of the European Organisation for Research and Treatment of Cancer (EORTC) breast reconstruction (BRECON) module. The primary objective was finalization of its scale structure. Secondary objectives were evaluation of its reliability, validity, responsiveness, acceptability and interpretability in patients with breast cancer undergoing mastectomy and reconstruction.
Methods
The EORTC module development guidelines were followed. Patients were recruited from 28 centres in seven countries. A prospective cohort completed the QLQ-BRECON15 before mastectomy and the QLQ-BRECON24 at 4–8 months after reconstruction. The cross-sectional cohort completed the QLQ-BRECON24 at 1–5 years after reconstruction, and repeated this 2–8 weeks later (test–retest reliability). All participants completed debriefing questionnaires.
Results
A total of 438 patients were recruited, 234 in the prospective cohort and 204 in the cross-sectional cohort. A total of 414 reconstructions were immediate, with a comparable number of implants (176) and donor-site flaps (166). Control groups comprised patients who underwent two-stage implant procedures (72, 75 per cent) or delayed reconstruction (24, 25 per cent). Psychometric scale validity was supported by moderate to high item-own scale and item-total correlations (over 0·5). Questionnaire validity was confirmed by good scale-to-sample targeting, and computable scale scores exceeding 50 per cent, except nipple cosmesis (over 40 per cent). In known-group comparisons, QLQ-BRECON24 scales and items differentiated between patient groups defined by clinical criteria, such as type and timing of reconstruction, postmastectomy radiotherapy and surgical complications, with moderate effect sizes. Prospectively, sexuality and surgical side-effects scales showed significant responsiveness over time (P < 0·001). Scale reliability was supported by high Cronbach's α coefficients (over 0·7) and test–retest (intraclass correlation more than 0·8). One item (finding a well fitting bra) was excluded based on high floor/ceiling effects, poor test–retest and weak correlations in factor analysis (below 0·3), thus generating the QLQ-BRECON23 questionnaire.
Conclusion
The QLQ-BRECON23 is an internationally validated tool to be used alongside the EORTC QLQ-C30 (cancer) and QLQ-BR23 (breast cancer) questionnaires for evaluating quality of life and satisfaction after breast reconstruction.

Abstract
The present study was conducted to test predictions of the oxidative stress theory of aging assessing reactive oxygen species production and oxidative stress resistance in cultured fibroblasts from 13 primate species ranging in body size from 0.25 to 120 kg and in longevity from 20 to 90 years. We assessed both basal and stress-induced reactive oxygen species production in fibroblasts from five great apes (human, chimpanzee, bonobo, gorilla, and orangutan), four Old World monkeys (baboon, rhesus and crested black macaques, and patas monkey), three New World monkeys (common marmoset, red-bellied tamarin, and woolly monkey), and one lemur (ring-tailed lemur). Measurements of cellular MitoSox fluorescence, an indicator of mitochondrial superoxide (O2(·-)) generation, showed an inverse correlation between longevity and steady state or metabolic stress-induced mitochondrial O2(·-) production, but this correlation was lost when the effects of body mass were removed, and the data were analyzed using phylogenetically independent contrasts. Fibroblasts from longer-lived primate species also exhibited superior resistance to H(2)O(2)-induced apoptotic cell death than cells from shorter-living primates. After correction for body mass and lack of phylogenetic independence, this correlation, although still discernible, fell short of significance by regression analysis. Thus, increased longevity in this sample of primates is not causally associated with low cellular reactive oxygen species generation, but further studies are warranted to test the association between increased cellular resistance to oxidative stressor and primate longevity.

Abstract
AbstractAimsThe perinatal period is a time of high risk of relapse for women with a history of bipolar affective disorder (BPAD). We describe the pregnancy management of women with BPAD and identify risk factors for postpartum relapse.MethodsThe case records of 78 women with BPAD referred to perinatal mental health services before conception, during pregnancy or the postpartum period, between 1998 and 2009 in Birmingham UK, were screened. In women who were managed during pregnancy, those who relapsed in the postpartum were compared with those who remained well.ResultsForty-seven percent of women with BPAD referred in pregnancy suffered postpartum relapse. Women who were unwell at referral, younger, with unplanned pregnancy, previous perinatal episodes or a family history of BPAD were more likely to suffer postpartum illness.ConclusionIdentifying risk factors for postpartum relapse enables us to individualise the estimation of a woman's risk and modify care plans accordingly. Duration of wellness prior to pregnancy is not associated with a lower risk of postpartum illness and so it is imperative that all women with BPAD receive referral in pregnancy.

Abstract
This article describes a program of research on effectively transporting the New Beginnings Program (NBP), a university-tested prevention program for divorced families, to community settings. The status of four steps in this research are described: (1) Selecting a community partner; (2) Developing effective methods of engaging parents; (3) Redesigning the NBP to be easily delivered with high quality and fidelity in community agencies, and (4) Adapting the NBP to meet the needs of the full population of divorcing families. The article concludes with a discussion of plans for an effectiveness trial to evaluate the NBP when delivered in community settings.

Abstract
Osteopontin (OPN) is a secreted extracellular phosphoprotein involved in diverse biologic functions, including inflammation, cell migration, and antiapoptotic processes. Here we investigate the neuroprotective potential of OPN to reduce cell death using both in vitro and in vivo models of ischemia. We show that incubation of cortical neuron cultures with OPN protects against cell death from oxygen and glucose deprivation. The effect of OPN depends on the Arg-Gly-Asp (RGD)-containing motif as the protective effect of OPN in vitro was blocked by an RGD-containing hexapeptide, which prevents integrin receptors binding to their ligands. Osteopontin treatment of cortical neuron cultures caused an increase in Akt and p42/p44 MAPK phosphorylation, which is consistent with OPN-inducing neuroprotection via the activation of these protein kinases. Indeed, the protective effect of OPN was reduced by inhibiting the activation of Akt and p42/p44 MAPK using LY294002 and U0126, respectively. The protective effect of OPN was also blocked by the protein synthesis inhibitor cycloheximide, suggesting that the neuroprotective effect of OPN required new protein synthesis. Finally, intracerebral ventricular administration of OPN caused a marked reduction in infarct size after transient middle cerebral artery occlusion in a murine stroke model. These data suggest that OPN is a potent neuroprotectant against ischemic injury.

Abstract
The 5,8-difluoro (4), 5-iodo (5), 8-iodo (6), and 5-trifluoromethyl (7) derivatives of trimetoquinol (TMQ, 1) have been synthesized and evaluated for their ability to stimulate beta 1 (guinea pig atria) and beta 2 (guinea pig trachea) adrenoceptors as well as for their inhibitory activity against U46619 [a thromboxane A2 (TXA2) mimetic]-mediated contraction of rat thoracic aorta and human platelet aggregation. Both 5 and 6 were considerably less active than TMQ on both beta-adrenergic systems and gave a rank order of stimulatory potency of 1 much greater than 6 greater than or equal to 5. Similarly, iodine substitution at either position also caused a reduction in TXA2 antagonist activity with a rank order potency of 1 greater than 6 much greater than 5. Compared to 1, however, 5-iodo-TMQ (5) showed a marked selectivity for blockade of U46619 responses in rat aorta over human platelets. On beta-systems, 4 had reduced potency compared to TMQ and was similarly nonselective. Introduction of a trifluoromethyl group at the 5-position of TMQ completely abolished both beta 1- and beta 2-adrenergic agonist activities while imparting weak antagonist activity on beta 1 receptors. On TXA2 systems, both 4 and 7 possessed significantly decreased inhibitory activity compared to TMQ. The synthetic approaches to the synthesis of 8-(trifluoromethyl)-TMQ (8) are also described. The enantiomers of the 8-fluoro derivative (3) of TMQ were separated on a preparative Chiralcel OD column and evaluated on beta-adrenergic systems and TXA2 systems. On beta-adrenergic systems, (S)-(+)-8-fluoro-TMQ was at least 10-fold more potent than (R)-(-)-8-fluoro-TMQ. Conversely, (R)-(-)-8-fluoro-TMQ was approximately 14-fold more potent as an antagonist of TXA2-mediated aggregation in human platelets than (S)-(+)-8-fluoro-TMQ. In contrast to platelets, (S)-(+)-8-fluoro-TMQ was an agonist in rat aorta whereas (R)-(-)-8-fluoro-TMQ was an antagonist.

Abstract
In this study, women's levels of ego development and their psychological difficulties were examined in relation to feelings in the maternal role. The sample consisted of 91 mothers from diverse socioeconomic backgrounds. Ego development was assessed by the Washington University Sentence Completion Test, and psychological difficulties were operationalized by self-reported global symptomatology, maternal substance abuse, and expressed anger. Outcome variables included feelings of satisfaction, distress, and support in the maternal role, as well as the degree to which negative and positive emotions were integrated in response to hypothetical vignettes of challenging everyday child-rearing experiences. Hypotheses were that women at high levels of ego development would show greater deterioration in the presence versus absence of self-reported adjustment problems than would those at lower levels. A series of interaction effects each indicated trends consistent with the hypotheses. These results add to accumulating evidence that tendencies toward self-examination, characteristic of high developmental levels, do not inevitably serve protective functions but may be linked with heightened reactivity to negative intrapsychic forces.

Abstract
BACKGROUND Polyamines (e.g., putrescine, spermidine, and spermine) are required for optimal cell growth. Inhibition of polyamine synthesis suppresses carcinogen-induced epithelial cancers, including colon cancer, in animal models. In a short-term phase IIa trial, we determined that low doses of alpha-difluoromethylornithine (DFMO), an inhibitor of ornithine decarboxylase (an enzyme involved in polyamine synthesis), reduced the polyamine content of normal-appearing rectal mucosa of subjects with a prior history of resected colon polyps. In a follow-up study, we have attempted to determine the lowest dose of DFMO that can suppress the polyamine content of rectal mucosa over a course of 1 year with no or minimal side effects. METHODS Participants were randomly assigned to daily oral treatment with a placebo or one of three doses (0.075, 0.20, or 0.40 g/m2) of DFMO. Baseline and serial determinations of polyamine levels in rectal mucosa and extensive symptom monitoring (including audiometric measurements, since DFMO causes some reversible hearing loss at higher doses) were performed over a 15-month period. RESULTS DFMO treatment reduced putrescine levels in a dose-dependent manner. Following 6 months of treatment, doses of 0.20 and 0.40 g/m2 per day reduced putrescine levels to approximately 34% and 10%, respectively, of those observed in the placebo group. Smaller decreases were seen in spermidine levels and spermidine:spermine ratios. Polyamine levels increased toward baseline values after discontinuation of DFMO. Although there were no statistically significant differences among the dose groups with respect to clinically important shifts in audiometric thresholds and nonaudiologic side effects, statistically significant higher dropout and discontinuation rates were observed in the highest dose group. CONCLUSIONS Polyamine levels in rectal mucosa can be continuously suppressed by daily oral doses of DFMO that produce few or no side effects. A dose of 0.20 g/m2 can be used safely in combination phase IIb or single-agent phase III chemoprevention trials.

Abstract
This study reports the results of an investigation to determine to what extent the influence of membrane lipids on the human erythrocyte sugar transporter protein activity (Caruthers, A. and Melchior, D.L. (1988) Annu. Rev. Physiol. 50, 257-271) is related to lipid/protein associations in the membrane bilayer. Differential scanning calorimetry was carried out on the human erythrocyte transport protein reconstituted into artificial bilayers formed from preselected lipids. it was found that the transport protein displays a preferential and in some cases strongly preferential affinity for specific lipid types. This association is a function of lipid head group, backbone and hydrocarbon chain length. It appears that the affinity of the transport protein for various lipids can correlate with the lipid's ability to influence transporter activity. This study further suggests that certain lipids (in this case sphingomyelin) can induce an oligomeric association of HEST monomers in the bilayer.

Abstract
This study tests the hypothesis that the administration of cyclocreatine prior to global ischemia enhances recovery of cardiac function during reperfusion. Two models were used. First, in a Langendorff-working heart model of normothermic cardioplegic arrest, rats (n = 6 per group) were injected intravenously with saline or cyclocreatine (600, 300, or 150 mg/kg). After 30 min or 2 h, hearts were excised and perfused in the Langendorff mode for 5 min and then in the working heart mode for 20 min. Normothermic arrest was induced by infusing warm St. Thomas solution once; then hearts were kept at 37 degrees C for 40 min. Following arrest, hearts were reperfused in the Langendorff mode for 15 min and then in the working mode for 30 min. Cyclocreatine consistently produced significantly better recovery of aortic flow and cardiac output compared to that of saline hearts. Second, in an intact canine model of cold cardioplegic arrest, adult mongrel dogs (n = 3 to 6 per group) underwent aortic cross-clamping for 1 h, followed by reperfusion on bypass for 45 min and off bypass for 4 h. Dogs were injected intravenously with saline or cyclocreatine (500 mg/kg) for 1 h before experiment. Post-bypass segmental contractility and cardiac output were significantly better in cyclocreatine hearts compared to that of controls. In a limited study, after a 3 h aortic cross-clamp time, cyclocreatine hearts achieved 91% baseline function while control hearts failed after 2 h. Results of this study suggest that cyclocreatine, without inotropic or chronotropic effect, protects the heart from global ischemic injury.

Abstract
Myogenic factors and TAL1 possess distinguishable DNA binding characteristics when they form a complex with basic helix-loop-helix (bHLH) proteins of class A. These characteristics were evident in electrophoretic mobility shift assays showing that complexes of myogenic factors and HTF4 displayed a relatively high affinity for the enhancer in the muscle creatine kinase gene, whereas TAL1 appeared to greatly attenuate the interaction of HTF4 with this enhancer. In addition, by forming a complex with HTF4 in solution, TAL1 could exert a negative effect on the interactions of HTF4 with elements that include E box motifs of microE2 (CAGCTG) and kappa E2/microE5 (CACCTG) type. Similarly, heterodimers containing TAL1 and the DNA binding domain of E47 exhibited a relatively weak affinity for microE2 and kappa E2/microE5 core motifs. The results of both studies invoked the hypothesis that in vivo TAL1 might act as a negative regulator of microE2 and kappa E2/microE5 sequence motifs by forming a complex with the products of the E2A and HTF4 genes. Support for this hypothesis was obtained by transient expression analyses where TAL1 was found to inhibit the activation effects produced by E2-5 and HTF4a on a reporter gene construct containing repeated microE2 and microE5 motifs, derived from the immunoglobulin gene enhancer.

Abstract
In this study, 6 anesthetized dogs underwent global cardiac arrest for 1 hour, followed by reperfusion on bypass for 45 minutes. The hearts were then weaned off cardiopulmonary bypass and monitored for an additional 2 hours. Using modified Boyden chambers, high levels of neutrophil chemotactic activity were detected (using a checkerboard analysis) in the coronary sinus effluents obtained during cardiac arrest. The activity tended to decline during reperfusion. Assay of myeloperoxidase (a marker for neutrophils) revealed an accumulation of large numbers of neutrophils in the right (14 +/- 1.1 x 10(4) cells/g wet weight) and left (16 +/- 1 x 10(4) cells/g wet weight) ventricles after 2 hours of reperfusion. Light microscopy evaluation confirmed the presence of neutrophils, not only in the ventricles, but also in a greater number in the right and left atria. Electron microscopy study of these hearts revealed the presence of mild reversible changes, indicating good preservation of the hearts during arrest. Results of this study provide evidence for an acute inflammatory reaction that takes place after cardiac operations and suggest a role for myocardial tissues in the initiation of such a response through their release of neutrophil chemotactic factors.
