Abstract
The application of an external 26 Tesla axial magnetic field to a D_{2} gas-filled capsule indirectly driven on the National Ignition Facility is observed to increase the ion temperature by 40% and the neutron yield by a factor of 3.2 in a hot spot with areal density and temperature approaching what is required for fusion ignition [1]. The improvements are determined from energy spectral measurements of the 2.45 MeV neutrons from the D(d,n)^{3}He reaction, and the compressed central core B field is estimated to be ∼4.9 kT using the 14.1 MeV secondary neutrons from the D(T,n)^{4}He reactions. The experiments use a 30 kV pulsed-power system to deliver a ∼3 μs current pulse to a solenoidal coil wrapped around a novel high-electrical-resistivity AuTa_{4} hohlraum. Radiation magnetohydrodynamic simulations are consistent with the experiment.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
Abstract
Introduction
We describe the use of a novel synthetic simulation pad for learning complex facial wound management including local flaps. The simulation pad is a cost effective and convenient model of facial wounds. We have compared the use of animal tissue to the simulation pad in the context of a workshop for surgical trainees and collected feedback from delegates.
Methods
Feedback was collected from 14 of 16 attending delegates.
Results
It was clear from feedback that animal tissue is not an ideal model of facial wounds with 71% of delegates stating that they did not consider it to be high-fidelity. The synthetic pad was rated more favourably with 100% of delegates reporting that it was a valuable exercise and well designed for local flaps.
Conclusions
It is imperative that training opportunities are high quality and useful to clinical practice. Techniques learnt in the context of a course or workshop are more valuable where targeted practice may occur following learning. The use of a synthetic pad is more amenable to continued practice where it may be taken home following a workshop. Feedback from this event suggests a well-designed synthetic pad is more useful than animal tissue in learning local flaps.

Abstract
The training pathway for oral and maxillofacial surgery (OMFS) has remained relatively stable for around 30 years. Circumstances surrounding the training pathway have changed including the priorities of individuals considering entering OMFS training. Run-through Specialty Training (ST1) OMFS posts (which include core surgical training) are oversubscribed while direct entry to Specialty Training (ST3) OMFS specialty recruitment rounds have unfilled posts, including places declined by appointable candidates. As part of a project to refine and improve OMFS recruitment and retention, data drawn from the British Association of Oral and Maxillofacial Surgeons (BAOMS) and the OMFS National Selection administering Deanery, Health Education England South West were scrutinised. Numbers of students starting second undergraduate degrees (medicine or dentistry) to pursue an OMFS career are increasing. Of a total of 43 candidates deemed appointable at OMFS ST1 selection but not offered an available post, 16 did not subsequently apply for ST3 selection. In the period studied (2015-20), of a total of 116 unfilled ST3 posts, 39 remained vacant because appointable candidates declined the available posts (33%). Appropriate changes to the current national selection processes could help address the perceived OMFS ST recruitment problems. By increasing the number of available ST1 posts, widening the window during which appointable candidates can continue into training and increasing prior experience recognition (including creating benchmarking processes prior to ST). These 3 clear, fair and transparent changes could reduce the current levels of attrition.

Abstract
Background: Colorectal cancer (CRC) presents considerable health, economic, and societal burden, and Australia has one of the highest incidence rates of this disease. Over a third of the Australian population live in nonmetropolitan areas and research has shown that they experience a range of health disadvantages that result in a higher disease burden and lower life expectancy. One of the main contributors of poorer CRC outcomes in rural Australia may be limited access to treatment facilities and optimal care; however, the extent to which geographical disparities exist in CRC management has not been systematically explored. Aim: To understand the nature of geographical variations in the clinical management and treatment of CRC (including surgery, chemotherapy, and radiotherapy) in Australia, incorporating clinical reports as well as peer-reviewed literature. Methods: A systematic review of published and gray literature was conducted. Five databases (CINAHL, PubMed, Embase, ProQuest, and Informit) were searched for articles published in English from 1990 to 2018. Studies were included if they assessed differences in clinical management according to geographical location; focused on CRC patients; and were conducted in Australia. Included studies were critically appraised using a modified Newcastle-Ottawa Scale. PRISMA systematic review reporting methods were applied. Results: Only 17 articles met inclusion criteria. All were of high (53%) or moderate (47%) quality. The evidence available may suggest that patients in nonmetropolitan areas are more likely to experience delays in surgery and are less likely to receive chemotherapy for stage III colon cancer and adjuvant radiotherapy for rectal cancer. Conclusion: The present review found limited information on clinical management across geographic regions in Australia and the synthesis highlights significant issues both for data collection and reporting at the population level. Where geographical disparities exist, these may be due to a combination of patient and system factors reflective of location. Population-level data regarding clinical management and treatment of CRC needs to be routinely collected to better understand geographical variations and inform future guidelines and policy.

Abstract
BACKGROUND Decreased lung function has health impacts beyond diagnosable lung disease. It is therefore important to understand the factors that may influence even small changes in lung function including obesity, physical fitness and physical activity. The aim of this study was to determine the anthropometric measure most useful in examining the association with lung function and to determine how physical activity and physical fitness influence this association. METHODS The current study used cross-sectional data on 4662 adults aged 40-79 years from the Canadian Health Measures Survey Cycles 1 and 2. Linear regression models were used to examine the association between the anthropometric and lung function measures (forced expiratory volume in 1 s [FEV1] and forced vital capacity [FVC]); R2 values were compared among models. Physical fitness and physical activity terms were added to the models and potential confounding was assessed. RESULTS Models using sum of 5 skinfolds and waist circumference consistently had the highest R2 values for FEV1 and FVC, while models using body mass index consistently had among the lowest R2 values for FEV1 and FVC and for men and women. Physical activity and physical fitness were confounders of the relationships between waist circumference and the lung function measures. Waist circumference remained a significant predictor of FVC but not FEV1 after adjustment for physical activity or physical fitness. CONCLUSIONS Waist circumference is an important predictor of lung function. Physical activity and physical fitness should be considered as potential confounders of the relationship between anthropometric measures and lung function.

Abstract
Using a bull's-eye hierarchical mapping technique (HMT), the present study examined placement of parents in adults' attachment networks over time. We hypothesized that attachment style would predict distance at which network members (mother, father, and romantic partner) would be placed from the core-self over time. Participants completed the HMT on two occasions, 12 months apart. Concurrently and over time, fathers were placed further from the core-self than mothers. Attachment style explained unique variance, beyond that accounted for by individual and relationship characteristics. Specifically, network members with whom participants reported greater attachment insecurity were placed further from the core-self concurrently. Mothers with whom participants reported greater attachment insecurity were placed further from the core-self over time. Unsatisfactory attachment relationships with father and partner and those marked by higher attachment insecurity were more likely to be excluded from attachment networks over time. Findings suggest that attachment style, relationship quality, romantic relationship status, and parents' marital status determine the placement of parents in adults' attachment networks.

Abstract
OBJECTIVES Sporadic Creutzfeldt Jakob Disease (sCJD) is a neurodegenerative disorder that typically presents as a rapidly progressive encephalopathy associated with various neurological features, culminating in akinetic mutism and death. Atypical cases, presenting with an isolated focal may cause diagnostic confusion. We described a series of patients with sCJD presenting with isolated language impairment. MATERIALS & METHODS We report a patient with sCJD referred to the NCJDRSU, who presented with isolated language impairment and subsequently identified all cases of sporadic CJD on the NCJDRSU database (covering the years 1990-2012) with an isolated language impairment presentation. RESULTS Nineteen patients (11 females) with sCJD (1.19% of all patients) had an isolated language disorder of at least 2 weeks duration as the first neurological symptom pattern. Mean age at onset was 68.28 years. No specific pattern of language affection was seen in these patients. Further progression usually affected more than one neurological domain, with all patients eventually developing cognitive decline and myoclonic jerks. The median duration of illness was 4 months. CSF 14.3.3 was positive and S100b level was elevated in all patients in whom it was performed. EEG and MRI showed typical features of sCJD in six patients each. Most patients showed MM genotype of PRNP codon 129. CONCLUSION This study highlights the fact that isolated aphasia can be the first neurological symptom approximately in 1% of patients with sCJD. The diagnosis is usually made with appearance of other clinical features and investigation results, but in a small minority, these may not be apparent for relatively long periods.

Abstract
Gene expression has recently been at the forefront of advance in personalized medicine, notably in the field of cancer and transplantation, providing a rational for a similar approach in rheumatoid arthritis (RA). RA is a prototypic inflammatory autoimmune disease with a poorly understood etiopathogenesis. Inflammation is the main feature of RA; however, many biological processes are involved at different stages of the disease. Gene expression signatures offer management tools to meet the current needs for personalization of RA patients' care. This review analyses currently available information with respect to RA diagnostic, prognostic and prediction of response to therapy with a view to highlight the abundance of data, whose comparison is often inconclusive due to the mixed use of material source, experimental methodologies and analysis tools, reinforcing the need for harmonization if gene expression signatures are to become a useful clinical tool in personalized medicine for RA patients.

Abstract
The effects of two fattening systems on muscle composition and fatty acid profile were determined in an experiment using samples of the longissimus dorsi (LD) muscle of 24 ram lambs (slaughter weight 29-31kg). The fattening systems were: (i) drylot (a mixture of maize, soybean, wheat and minerals) and (ii) grazing (Cynodon dactylon). The lambs fattened in the drylot system presented higher fat levels (p<0.01), but lower concentrations of moisture (p<0.01) and cholesterol (p<0.05). The lipid content presented a negative correlation with moisture and protein. In lambs fattened in the drylot system increasing levels of fatness of LD muscle were associated with a decrease (p<0.05) in myristic and palmitic acids, but myristic, palmitic and linoleic acids increased (p<0.05) as the cholesterol levels of the muscles increased.

Abstract
Background and Purpose—
Strokes have especially devastating implications if they occur early in life; however, only limited information exists on the characteristics of acute cerebrovascular disease in young adults. Although risk factors and manifestation of atherosclerosis are commonly associated with stroke in the elderly, recent data suggests different causes for stroke in the young. We initiated the prospective, multinational European study Stroke in Young Fabry Patients (sifap) to characterize a cohort of young stroke patients.
Methods—
Overall, 5023 patients aged 18 to 55 years with the diagnosis of ischemic stroke (3396), hemorrhagic stroke (271), transient ischemic attack (1071) were enrolled in 15 European countries and 47 centers between April 2007 and January 2010 undergoing a detailed, standardized, clinical, laboratory, and radiological protocol.
Results—
Median age in the overall cohort was 46 years. Definite Fabry disease was diagnosed in 0.5% (95% confidence interval, 0.4%–0.8%; n=27) of all patients; and probable Fabry disease in additional 18 patients. Males dominated the study population (2962/59%) whereas females outnumbered men (65.3%) among the youngest patients (18–24 years). About 80.5% of the patients had a first stroke. Silent infarcts on magnetic resonance imaging were seen in 20% of patients with a first-ever stroke, and in 11.4% of patients with transient ischemic attack and no history of a previous cerebrovascular event. The most common causes of ischemic stroke were large artery atherosclerosis (18.6%) and dissection (9.9%).
Conclusions—
Definite Fabry disease occurs in 0.5% and probable Fabry disease in further 0.4% of young stroke patients. Silent infarcts, white matter intensities, and classical risk factors were highly prevalent, emphasizing the need for new early preventive strategies.

Abstract
OBJECTIVE To determine the clinical efficacy and safety of a cremophor-free formulation of paclitaxel (Paccal Vet, Oasmia Pharmaceuticals) in dogs with mast cell tumours. METHODS Paccal Vet was administered at a median dose of 145 (range, 135 to 150) mg/m(2) intravenously once every 21 days for three cycles to 29 dogs with macroscopic grade 2 or 3 mast cell tumour. Efficacy was assessed by tumour response (Response Evaluation Criteria in Solid Tumours version 1.0) and performance status score. Progression-free survival, quality of life and safety/adverse events were also evaluated. Clinical safety was assessed by clinicopathological analyses and recording of adverse events. RESULTS Complete or partial response was observed in 59% of dogs. Performance status score remained constant or improved for 20 dogs and decreased by one grade for 9 dogs. Median time to progression was 247 (range, 42 to 268) days. Expected, transient frequently subclinical adverse events (primarily grade 3/4 neutropenia and grade 1/2 leukopenia) were observed in the majority of dogs. Nine dogs were euthanased and one dog died due to disease progression. CLINICAL SIGNIFICANCE Paccal Vet appears to be a clinically safe and effective treatment for canine mast cell tumours. Further controlled confirmatory investigation is warranted.

Abstract
A 64-year-old male who had previously undergone an aortic valve replacement and replacement of the ascending aorta presented with an 8 cm descending aortic aneurysm. A left thoracotomy was required to allow replacement of the aorta. However, due to longitudinal as well as transverse expansion, visualisation of the aortic arch was compromised, preventing cross-clamping of the proximal aorta. Cardiopulmonary bypass and deep hypothermic circulatory arrest were, therefore, required. An unusual method of cardioplegia delivery was used for myocardial protection, utilising a Foley catheter under direct vision as an alternative to more expensive percutaneous peripheral endoclamp devices. We also describe an unusual cardiopulmonary bypass circuit, with the dual use of a left atrial cannula for venting and also for re-establishing perfusion during de-airing.

Abstract
A number of studies have identified differential kavalactone activity against a variety of molecular targets, including P-glycoprotein (Pgp), platelet monoamine oxidase (MAO-B), transcription factor binding domains, pregnane X (PXR) and GABA receptors, and cytochrome P450 and cyclo-oxygenase (COX) enzymes. The molecular structure of the kavalactones possesses a pharmacophore for several of these targets. In most cases, conformational stability is more significant than the substituents present. The analysis of these pharmacophores provides important insights for future medicinal chemistry-based approaches to kavalactone-type drugs.

Abstract
While cases of severe kava hepatotoxicity have been reported, studies examining the toxicity of individual kavalactones are limited. The present study examined the in vitro hepatotoxicity of kavain, methysticin and yangonin on human hepatocytes (HepG2) and the possible mechanism(s) involved. Cytotoxicity was assessed using lactate dehydrogenase (LDH) and ethidium bromide (EB) assays. The mode of cell death was analysed with acridine orange/ethidium bromide dual staining with fluorescence microscopy. Glutathione oxidation was measured using the ortho-phthalaldehyde (OPT) fluorescence assay. Kavain had minimal cytotoxicity, methysticin showed moderate concentration-dependent toxicity and yangonin displayed marked toxicity with ~ 40% reduction in viability in the EB assay. Acridine orange/ethidium bromide staining showed the predominant mode of cell death was apoptosis rather than necrosis. No significant changes were observed in glutathione levels, excluding this as the primary mechanism of cell death in this model. Further studies may elucidate the precise apoptotic pathways responsible and whether toxic kavalactone metabolites are involved.

Abstract
Anthelmintics are currently the most common method of worm control. The emergence of worms with multiple-drug resistance and issues of residues in the food chain make alternative parasite control measures a priority. To develop improved and sustainable methods for controlling Haemonchus contortus such as genetic selection of resistant sheep, a better understanding of the host-parasite relationship is required. A trial was undertaken using sheep surgically implanted with abomasal fistulas to enable sequential biopsy of the abomasal mucosa during trickle infection with two strains of H. contortus. These were ivermectin-resistant CAVR and ivermectin-sensitive McMaster. From a gross parasitology perspective, this approach enabled the effect of developing immunity to be observed on both the establishment and maturation of two CAVR doses within and between groups. Since the only difference in parasite treatment between the groups was the staggering of the two CAVR doses, microarray results from biopsies taken on the same day in different groups were combined and compared between different biopsy dates to observe differential gene transcription over time. Differential gene transcription was detected by comparing transcription in our array data between different biopsy dates using a low P value screen (P<0.01) and by compiling a list of 82 immunoparasitology-related genes and examining transcription in this list with a higher P value screen (P<0.05). Our microarray data were validated in silico by comparison with intelectin 2, trefoil factor 3, calcium activated chloride channel and mucin 5 from other gene transcription studies and with phenotypic data such as the response by gammadelta T cells and immunoglobulins to H. contortus. The first four genes are involved in non-specific responses to infection and mucosal healing. These were upregulated at the early time points and intelectin 2 remained prominent throughout the trial. As the trial progressed, immunoglobulin genes became strongly upregulated. These included IgCgamma IgG2a heavy chain constant region, IGHE immunoglobulin heavy constant epsilon and IGHM immunoglobulin heavy constant mu.

Abstract
To determine whether fistulation and differing strains of Haemonchus contortus complicate genome analysis of the host response to infection, two pilot experiments examined parasite development and gene expression in the abomasal mucosa of parasitised sheep. No significant differentially-expressed genes were detected in a comparison between ivermectin-susceptible McMaster and ivermectin-resistant CAVR strains of H. contortus. This demonstrated that the sheep response was not significantly altered by the ivermectin-resistance status of the parasite. However, sheep infected with McMaster strain had a significantly lower proportion of larvae and a higher mean FEC at post-mortem than sheep infected with CAVR, suggesting that McMaster larvae advance to patency faster than CAVR larvae. Abomasal fistulation resulted in significant upregulation of three genes and significant downregulation of two genes. Fistulated sheep had significantly lower FEC than the other groups but the proportion of larvae at post-mortem was not significantly different to other groups infected with the same strain (CAVR). Hence fistulation does not alter establishment of the CAVR isolate, but may slow its progression to patency. The observation that different H. contortus strains and abomasal fistulation induced minimal changes in mucosal gene expression validated the design of a subsequent experiment (manuscript in preparation) where sequential biopsies taken during infection were analysed by microarray to describe the molecular responses which inhibit larval establishment.

Abstract
BACKGROUND The incidence of malignant melanoma is increasing worldwide and patients are being diagnosed earlier with thinner primary lesions. Most patients with very thin melanoma (Breslow thickness < 0.76 mm) are cured by surgery but 2-18% relapse locally or with distant metastases. OBJECTIVES The objective of this study was to establish potential new prognostic markers in very thin melanoma. METHODS We identified a group of subjects with relapsing very thin primary cutaneous melanoma and a matched control group who had not relapsed. We investigated the expression of p16, Helix pomatia agglutinin (HPA), CD95 and CD95 ligand (CD95L) by immunohistochemistry on paraffin-embedded tissue sections from the subject group, their subsequent metastases and the control group. RESULTS Reduced p16 expression was significantly associated with relapse in very thin melanoma (P = 0.0129). Loss of p16 expression was also found in 76% of metastases. There was no significant association between HPA, CD95 or CD95L expression and subsequent relapse. CONCLUSIONS This work is the first to show a significant loss of p16 in relapsing very thin melanoma.

Abstract
Osteoprotegerin (OPG), a key regulator of bone resorption, is hypothesized to have a role in prostate cancer (CaP) bone metastasis. As advanced CaP is treated by androgen ablation, we examined if androgen modulates OPG expression by CaP cell lines in vitro. Basal levels of secreted OPG protein were significantly greater in androgen-independent PC-3 cells compared with androgen-responsive LNCaP-FGC cells (P<0.001); OPG was not detected in the androgen-responsive CaP cell lines LAPC-4 or DuCaP. Treatment with 5alpha-dihydrotestosterone (5alpha-DHT) significantly decreased OPG protein levels in both PC-3 and LNCaP-FGC, with maximal suppression using 10(-9)-10(-7) M 5alpha-DHT in PC-3 (P<0.01; day 3), and using 10(-10)-10(-9) M 5alpha-DHT in LNCaP-FGC cells (P<0.01; day 6). OPG messenger RNA levels were not significantly altered by this 5alpha-DHT treatment. Co-treatment with 10(-6) M flutamide blocked 5alpha-DHT inhibition of OPG protein expression in LNCaP-FGC cells. These data suggest that androgen may modulate OPG protein levels in CaP cell lines in vitro using a post-transcriptional mechanism.

Abstract
In the UK the incidence of malignant melanoma is increasing and more patients with thinner primary lesions are diagnosed earlier. Most patients with very thin melanoma (< 0.76 mm Breslow thickness) are cured by surgical excision, however, 2-18% relapse over 0-11 years with local or distant metastatic disease and may die. There are still no recognized prognostic or predictive, clinical, serological or molecular markers that accurately determine which of these very thin melanoma will relapse: the Breslow thickness remains the single most important prognostic factor for melanoma in general. Improved prognostic indicators are therefore needed for this rare, but important, unusually aggressive group, to better direct new invasive and expensive investigations and treatment. This article reviews the clinical and histological aspects of relapsing very thin melanoma and discusses the findings of several recent studies, including our own. There is no clinical or biological evidence to support either wide surgical excision or sentinel node biopsy in these patients.

Abstract
Previously we have shown that polioviruses with mutations that disrupt the predicted secondary structure of the 5' noncoding region of domain V are temperature sensitive for growth. Non-temperature-sensitive revertant viruses had mutations that re-formed secondary structure by a direct back mutation of changes in the opposite strand. We mutated unpaired regions and selected revertants of viruses with single base deletions, where no obvious back mutation was available in order to gain information on secondary structure. Results indicated that conservation of length of a three base loop between two double-stranded stems was essential for a functional domain V to form. The requirement for the unpaired "hinge" base at 484 which is implicated in the attenuation of Sabin 2 was also confirmed. Results also underline the necessity for functional folding over local secondary structure stability.

Abstract
PURPOSE Patients with severe limbal deficiencies are unable to maintain a stable corneal surface. If sheets of cultured allogeneic corneal epithelium could be prepared from eye banked corneal limbal rings, which are normally discarded after keratoplasty, the sheets may be beneficial for grafting onto patients with limbal stem cell deficiencies. METHOD Biopsies of limbal tissue (2-3 mm2) removed from organ-cultured corneal limbal rings or from fresh whole globes were either trypsinized or set up as explants to assess their potential for corneal epithelial cell production. RESULTS Several biopsies were taken from each of 21 organ-cultured limbal rings and 10 fresh cadaveric globes. Cultures were generated from every cadaveric eye (10/10), although not all biopsies from the same eye gave rise to cultures. Confluent sheets of cultured cells were also produced successfully from limbal rings that had been in organ culture for up to 25 days, but the success rate from limbal ring material was variable (14/21). An analysis of parameters associated with each limbal ring was carried out in an attempt to identify the reasons for the different efficiencies of epithelial production. No obvious single parameter correlation was detected, although there was a trend to poorer efficiency with increased donor age. CONCLUSIONS Confluent sheets of cultured corneal epithelial cells, suitable for grafting, can be produced from limbal tissue taken from eye bank organ-cultured corneas, although it takes longer, on average, to reach confluence (17-21 days) than an equivalent sample from a fresh eye (9-12 days).

Abstract
Wound healing in the skin depends upon the availability of appropriate trace metals as enzyme cofactors and structural components in tissue repair. The present study forms part of a series of experimental investigations to examine the influence of xenobiotic elements with no known nutritional function and which are known to compete with essential trace metals. It was designed to investigate further the importance of trace metals in wound healing as an aid to wound management and to identify mechanisms of nonhealing which constitute a major problem in human medicine. Surgically induced skin wounds in young adult male Wistar rats were exposed topically to 0.2 ml of 0.01, 0.10 or 1.0% cadmium chloride (aq.) daily for up to 10 days. Control wounds received de-ionized water only. Wounds exposed to cadmium chloride at 0.01 or 0.10% healed in a similar fashion to controls and exhibited a comparable histological profile with metallothionein distribution. Wounds receiving 1.0% cadmium chloride failed to heal or fully re-epithelialize within 7 days and animals were humanely killed. They showed a persistent mass of inflammatory cell infiltration, oedema, wound debris and aberrant epidermal cell growth. Metallothionein concentrations in the epidermis and fibroblasts of the papillary dermis increased greatly by 5 days postwounding and remained high through the observation period. Cadmium was identified in the liver, kidney and wound sites. In the wound, 1.0% cadmium chloride induced statistically significant (P > 0.001) changes in local concentrations of zinc and calcium at key stages in the healing process, and as a consequence disturbed the trace metal balance necessary for normal wound repair. Zinc levels were increased twofold after 7 days, but calcium was markedly reduced. Local changes in the distribution of metallothionein indicate interaction of cadmium and trace metal carrier proteins as a probable mechanism for impaired wound healing. The cytotoxicity of cadmium is considered to be largely responsible.

Abstract
BACKGROUND Psoriasis is a heterogeneous disease in its clinical expression. Both genetic and environmental factors are thought to contribute to the pathogenesis of the inflammatory and hyperproliferative components of the typical skin lesions. Predisposing genetic influences include associations with human leucocyte antigens (HLA) of which that with HLA-Cw6 is the strongest. Guttate psoriasis is a specific clinical manifestation of psoriasis frequently associated with group A beta-haemolytic streptococcal throat infection. OBJECTIVES We set out to determine whether further clinical subdivision of psoriasis is associated with tighter correlation with HLA-C alleles. PATIENTS/METHODS We determined the HLA-C locus genotype of 29 caucasian patients with guttate psoriasis presenting consecutively with guttate psoriasis associated with a history of a sore throat and/or an antistreptolysin O titre > 200 IU mL-1. Polymerase chain reaction typing using sequence-specific primers was used to detect all known HLA-C alleles. These data were compared with a control population of 604 random caucasian cadaver donors. RESULTS All patients (100%) with guttate psoriasis carried the Cw*0602 allele compared with 20% of the control population (odds ratio = infinity; 95% confidence limits 25.00-infinity; Pcorrected < 0.0000002). CONCLUSIONS This result is consistent with HLA-Cw*0602 playing a part directly in the pathogenesis of guttate psoriasis.

Abstract
Although high-functioning individuals with autistic disorder (i.e. autism and Asperger syndrome) are of normal intelligence, they have life-long abnormalities in social communication and emotional behaviour. However, the biological basis of social difficulties in autism is poorly understood. Facial expressions help shape behaviour, and we investigated if high-functioning people with autistic disorder show neurobiological differences from controls when processing emotional facial expressions. We used functional MRI to investigate brain activity in nine adults with autistic disorder (mean age +/- standard deviation 37 +/- 7 years; IQ 102 +/- 15) and nine controls (27 +/- 7 years; IQ 116 +/- 10) when explicitly (consciously) and implicitly (unconsciously) processing emotional facial expressions. Subjects with autistic disorder differed significantly from controls in the activity of cerebellar, mesolimbic and temporal lobe cortical regions of the brain when processing facial expressions. Notably, they did not activate a cortical 'face area' when explicitly appraising expressions, or the left amygdala region and left cerebellum when implicitly processing emotional facial expressions. High-functioning people with autistic disorder have biological differences from controls when consciously and unconsciously processing facial emotions, and these differences are most likely to be neurodevelopmental in origin. This may account for some of the abnormalities in social behaviour associated with autism.

Abstract
Polioviruses are single-stranded RNA viruses with an unusually long noncoding region (NCR) at the 5' end predicted to have an elaborate secondary structure made up of six domains. Mutations in domain V of the poliovirus 5'NCR that disrupt secondary structure are responsible for attenuation of the virus and a temperature-sensitive (ts) phenotype in vitro. In addition to direct back mutation or compensatory second site mutation in the 5'NCR as previously documented, the ts phenotype was found to be compensated for in monkey kidney cells in vitro by a coding change in the protease 2A. These coding changes were found throughout the protease with no obvious pattern or trend. They were not all found to be equivalent and limited in ability to compensate for the severest domain V disruption. The compensatory effect of the 2A changes was found to be cell specific, having no effect on monkey neurovirulence and in a mouse cell line but a significant effect in two monkey cell lines and a human epithelial line.

Abstract
We have performed a retrospective review of the use of a percutaneous gastrojejunostomy in patients with amyotrophic lateral sclerosis (ALS). Forty-one patients with initial bulbar manifestations of ALS and 32 patients with initial limb manifestations underwent a percutaneous gastrojejunostomy under fluoroscopic control using the Rankin gastrojejunostomy tube. Survival characteristics were compared with 86 bulbar onsetting and 207 limb onsetting ALS patients who did not require nutritional support. The 30-day mortality rate was 9.6% (respiratory death in three bulbar onsetting patients and four limb onsetting patients) and the 30 day morbidity rate was 4.1% (one operative site infection and intraperitoneal leakage in two patients). The most frequent long-term complication was the requirement for tube changing (blockage in six; dislodgment in two). Gastric reflux was not described amongst the treated patients. Overall survivorship (symptom onset to death) was less in the bulbar onsetting patients receiving a gastrojejunostomy tube than in the control population (median survival 22.0 vs. 33.7 months, respectively, P=0.005). As a group, the median survivorship for limb onsetting patients was not different for those receiving a gastrojejunostomy than for those who did not. However, a significant reduction in survival was observed in limb onsetting patients receiving a gastrojejunostomy early in the course of their disease (P=0.001) compared to those with a longer duration prior to the procedure. This was not observed in the bulbar onsetting patients. In both patient populations, no relationship was observed between survival post-gastrojejunostomy and the severity of pulmonary involvement at the time of the intervention, serum chloride, or age at onset. These studies demonstrate that a percutaneous gastrojejunostomy is a well-tolerated and safe alternative technique for enteral nutritional support in ALS patients. It also offers the advantage of not requiring either a general anaesthetic at the time of the procedure or instrumentation through the oropharynx. We have also observed that limb onsetting patients requiring a gastrojejunostomy early in the course of their illness are in a distinctive, less favorable, prognostic group.

Abstract
Spatial working memory (SWM) was investigated in 15 patients with Asperger's syndrome (AS) comparing their performance to 18 age- and IQ-matched control subjects. An additional comparison was made with 20 unilateral frontal excision patients [9 right (RFL); 11 left (LFL)] and with 38 unilateral temporal lobectomy patients [18 right (RTL); 18 left (LTL)], the frontal and temporal lobe patients having separate matched control groups. SWM was tested using the Executive Golf Task, a test that also measures spatial strategy formation. The AS group showed a substantial deficit on SWM, but no impairment in strategy formation. The LFL showed the same pattern of impairment, but with a less substantial deficit. The RFL group showed a large deficit, but some of this was accounted for by a strategy formation impairment. Of the temporal lobe lesions groups, only the RTL group was impaired on SWM, but this group showed normal strategy formation. It was concluded that the SWM deficit in AS may reflect a more general difficulty in accessing different types of representations in order to guide voluntary behavior, providing at least a partial explanation for the executive deficits found in AS.

Abstract
Metalloenzymes have an important role in repair and regenerative processes in skin wounds. Demands for different enzymes vary according to the phase in the healing cascade and constituent events. Sequential changes in the concentrations of calcium, copper, magnesium and zinc were studied in the incisional wound model in the rat over a 10 d period. Copper levels remained low (< 10 microg/g dry weight) throughout, but calcium, magnesium and zinc increased from wounding and peaked at about 5 d at a time of high inflammation, granulation tissue formation and epidermal cell proliferation. Metal concentrations declined to normal by 7 d when inflammation had regressed, re-epithelialisation of the wound site was complete and the 'normalisation' phase had commenced. Although the wound was overtly healed by 10 d, the epidermis was still moderately hyperplastic. In view of competitive binding of trace metals at membrane receptors and carrier proteins, the ratios or balance between these trace metals was examined and the significance is discussed. Using immunocytochemistry, we demonstrated increases in metallothionein immunoreactivity as an indication of zinc and copper activity in the papillary dermis and in basal epidermal cells near the wound margin 1-5 d after wounding. This is consistent with metalloenzyme requirements in inflammation and fibrogenesis. Calmodulin, a major cytosolic calcium binding protein was highest in maturing keratinocytes and in sebaceous gland cells of normal skin; it was notably more abundant in the epidermis near the wound margin and in re-epithelialising areas at a time when local calcium levels were highest.

Abstract
STUDY DESIGN One group; pretest, posttest design. OBJECTIVE To assess the effect of a 2-hour cheerleading practice on the anterior knee laxity, hamstring extensibility, and dynamic postural stability (preferred stance leg during vision-denied unilateral stance) of 17 nonimpaired members of a college cheerleading team (8 females, 9 males; 18-25 years old). BACKGROUND Anterior knee laxity and hamstring extensibility increase following exercise. The relationship between exercise induced anterior knee laxity, hamstring extensibility, and dynamic postural stability, however, has not been examined. METHODS AND MEASURES Pre- and postpractice measurements were compared using paired t tests and Bonferroni's correction for multiple comparisons. A 3 x 2 analysis of variance (force level applied to the arthrometer by condition) and Tukey honest significant difference post hoc test were used to evaluate specific arthrometer force level by condition effects (P < .05). RESULTS Mean laxity at 133 N and hamstring extensibility increased (mean +/- SD) 1.5 +/- 1 mm and 3 +/- 4 degrees, respectively, following practice. Mean medial-lateral stabiliometer platform angulation (frontal plane position) moved medially following practice (2.9 +/- 3 degrees) and produced a weak correlation with increased knee laxity (r = 0.58). Hamstring extensibility did not significantly relate to stabiliometry or knee laxity variables. CONCLUSIONS The relationship between the medially directed platform angulation and the increase in anterior knee laxity following cheerleading practice suggests a relationship between subtalar joint position and anterior cruciate ligament strain.

Abstract
The predominant itchy folliculitis associated with human immunodeficiency virus (HIV) infection appears to be an eosinophilic folliculitis (EF). This is characterized by lytic degeneration of sebaceous glands and an inflammatory infiltrate in which eosinophils and CD8+ T lymphocytes predominate. All patients have low CD4 counts and present late on in their HIV disease. Lesional distribution is mainly truncal, with a significant proportion also having facial involvement. Our prospective survey has shown that it is impossible to differentiate clinically between infective folliculitis and EF, and we recommend therefore that all cases are biopsied. We review the clinicopathological and immunological aspects of HIV-associated itchy folliculitis, in particular HIV-associated EF as well as current theories on pathogenesis and treatment. We suggest that HIV-associated EF is an autoimmune disease with the sebocyte or some constituent of sebum acting as the autoantigen.

Abstract
The particular virulence of Plasmodium falciparum compared with the other malaria species which naturally infect humans is thought to be due to the way in which the parasite modifies the surface of the infected red cell. Approximately 16 hours into the asexual cycle, parasite encoded proteins appear on the red cell surface which mediate adherence to a variety of host tissues. Binding of infected red cells to vascular endothelium, a process which occurs in all infections, is thought to be an important factor in the pathogenesis of severe disease where concentration of organisms in particular organs such as the brain occurs. Binding to uninfected red cells to form erythrocyte rosettes, a property of some isolates, is linked to disease severity. Here we summarise the data on the molecular basis of these interactions on both the host and parasite surfaces and review the evidence for the involvement of particular receptors in specific disease syndromes. Finally we discuss the relevance of these data to the development of new treatments for malaria.
