Abstract
BACKGROUND Palmar burn injuries are common in young children and can result in contracture. METHODS A prospective longitudinal study describes outcomes of palm and digit extension splint use following burn in 75 children (83 hands) aged < 5 years and determines whether specific cutaneous functional units (CFUs) are associated with early signs of contracture (ESC). Outcomes were assessed up to 9-18 months following burn. Routine clinical data was collected at therapy reviews. RESULTS Children were splinted > 12 h/day for a mean of 158 days following burn. The mean time to splint cessation was 264 days following burn. Fourteen hands developed ESC (17%): 12 hands had full ROM restored following conservative management, 2 hands (3%) progressed to contracture. Hands that developed ESC had greater healing time (p = 0.002), greater number of CFUs affected (p < 0.001), and greater number of immediate first webspace and extended first webspace CFUs affected (p = 0.002, p < 0.001 respectively). ESC risk increases for each day to heal (odds ratio [OR] 1.1, 95% CI 1.0-1.2) and each CFU in extended first webspace (OR 2.8, 95% CI 1.5-5.0). CONCLUSION Early and intensive splinting following palmar burn results in excellent ROM. Burns involving more CFUs or the first webspace are associated with ESC.

Abstract
BACKGROUND Parents may experience challenges implementing their child's therapeutic treatment following burn. METHODS A mixed methods study was conducted to explore the parent experience of intensive splinting following palmar burns in young children (median age 16 months [IQR 14]). Thirteen parents were interviewed after cessation of their child's splinting (mean 12 months [SD 2] following burn). Parent interviews were semi-structured with open-ended questions and conducted one-to-one. Inductive thematic analysis was completed by two researchers with consensus achieved through discussion and agreement from third researcher. Themes were triangulated with quantitative data, including range of motion (ROM), scar, developmental and quality of life outcomes. RESULTS Children used the splint intensively (>12-24 h/day) for median 179 days (IQR 74) with all splinting ceased by median 275 days (IQR 105). All children had full ROM at scar maturation. Thematic analysis revealed two main themes: parents perceive the impact of splinting to be greater on them than their child and parents perceive outcomes to be more important than burden. Parents described the importance of routine and therapeutic relationships in ongoing engagement with intervention. CONCLUSION Parents consider intensive splinting to impact them more than their child with burden of care manageable considering overall outcomes.

Abstract
OBJECTIVE Fatigue is the second most prevalent symptom in chronic obstructive pulmonary disease (COPD), yet it is often undetected in pulmonary rehabilitation. The aim of this study was to assess the validity of using a health status questionnaire (COPD Assessment Test [CAT] and CAT-energy score) to detect fatigue in people with COPD referred to a pulmonary rehabilitation program. METHODS This study was a retrospective audit of people with COPD referred to pulmonary rehabilitation. The validity of the CAT-total score and CAT-energy score for detecting fatigue was analyzed compared to a validated fatigue questionnaire, the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). Cut-off values defining fatigue included a CAT-total score ≥ 10, a CAT-energy score ≥ 2, and a FACIT-F score ≤ 43. Data were analyzed using 2 × 2 tables from which accuracy, sensitivity, specificity, and likelihood ratios were calculated. RESULTS Data from 97 participants with COPD (age in years mean [SD] = 72 [9]; FEV1% predicted mean [SD] = 46% [18]) were used. The FACIT-F score ≤ 43 classified 84 participants (87%) as fatigued. A CAT-total score ≥ 10 yielded an accuracy of 0.87, sensitivity of 0.95, specificity of 0.31, and positive and negative likelihood ratios of 1.38 and 0.15, respectively. A CAT-energy score ≥ 2 yielded an accuracy of 0.85, sensitivity of 0.93, a specificity of 0.31, and positive and negative likelihood ratios of 1.34 and 0.23, respectively. CONCLUSION The CAT-total score is an accurate and sensitive measure for fatigue, and the CAT could be an appropriate tool to screen for fatigue in people with COPD referred to pulmonary rehabilitation. IMPACT Use of the CAT as a screening tool for fatigue has the potential to improve clinician awareness of fatigue, simplify the pulmonary rehabilitation assessment process by reducing survey burden, and inform fatigue management, which may subsequently reduce the symptomatic burden of fatigue in people with COPD.

Abstract
Identification of children at risk of palmar burn scar is important for early initiation of scar management. This study determined the interrater reliability of face-to-face and photographic assessments of 29 palmar cutaneous functional units (CFUs) predicted to scar following palmar burn. The validity of photographic compared to face-to-face assessment, and the predictive validity of both assessment types to identify scarring at 3 to 6 months following burn, was also established. Thirty-nine children (40 hands) post burn injury were assessed face-to-face in the clinical setting, following healing of their palmar burn, by three burn therapists. Photographs of the children's hands at initial assessment were assessed by the same therapists a minimum of 6 months later. To determine which CFUs scarred, children were reassessed face-to-face in the clinical setting 3 to 6 months following their burn. For analysis, 29 CFUs were merged into eight separate groups to determine the number of CFUs predicted to scar per CFU group for face-to-face and photographic assessments. The range of agreement for individual CFUs within CFU groups was also calculated for both assessment types. Excellent interrater reliability was established for face-to-face assessment in all eight CFU groups (ICC2,1 0.83-0.96). Photographic assessment demonstrated good to excellent interrater reliability in six CFU groups (ICC2,1 0.69-0.90) and validity in seven CFU groups (ICC2,1 0.66-0.87). Good to excellent predictive validity was established for both assessment types in seven CFU groups (face-to-face ICC2,1 0.60-0.95, photographic ICC2,1 0.69-0.89). Experienced therapists can reliably assess CFUs face-to-face or via photographs and predict future scar development.

Abstract
AIM To determine the level of heterogeneity in delivery of computed tomography (CT) colonography services and develop a workforce calculator that accommodates the variation identified. MATERIALS AND METHODS A national survey, based on the "WHO workforce indicators of staffing need", established activity standards for essential tasks in delivery of the service. From these data a workforce calculator was designed to guide the required staffing and equipment resource by service size. RESULTS Activity standards were established as mode responses >70%. Service homogeneity was greater in areas where professional standards and guidance were available. The mean service size was 1,101. Did not attend (DNA) rates were lower where direct booking was available (p<0.0001). Service sizes were larger where radiographer reporting was embedded in reporting paradigms (p<0.024). CONCLUSION The survey identified benefits of radiographer-led direct booking and reporting. The workforce calculator derived from the survey provides a framework to guide the resourcing of expansion while maintaining standards.

Abstract
BACKGROUND Palmar contracture in young children can have significant developmental consequences. Despite this, objective techniques to measure palmar range of movement and quantify contracture in young children are limited. PURPOSE The purpose of this study was to determine the reliability of hand span and hand length measures in young children and to establish whether there is any association with age, sex and presence of a palmar burn injury in the reliability of these measures. The study also sought to determine the normative difference and establish a cut off value for the between-hand difference to identify loss of movement in 1 hand. STUDY DESIGN Cross sectional METHODS: Forty-four children aged 0 to <5 years were recruited. Twenty-two children had a unilateral palmar burn injury and 22 did not have a palmar burn injury. Each child's hand span and hand length were measured 3 times. This was performed twice by the first assessor and once by the second assessor. Intraclass correlation coefficients were calculated to determine the intra-rater and inter-rater reliability. The largest of the 3 values for both hand span and hand length from the first assessor's first assessment were used to determine the normative between-hand difference. Outliers were removed prior to determining the normative difference. Children were considered outliers if their between-hand difference in hand span and/or hand length was in the top 5% of values. RESULTS Excellent reliability was established for hand span and hand length measures for the whole group (intra-rater ICC2,1 ≥0.95, inter-rater ICC2,1 ≥0.94). The mean normative between-hand difference for both measures was 2 mm. The cut-off for the normative difference in hand span was <9 mm and hand length was <6 mm. CONCLUSION This measurement technique has excellent reliability and could be a useful method to quantify palmar range of movement and identify contracture in young children with unilateral hand injuries.

Abstract
Resulting from impaired collagen turnover, fibrosis is a hallmark of adipose tissue (AT) dysfunction and obesity-associated insulin resistance (IR). Prolidase, also known as peptidase D (PEPD), plays a vital role in collagen turnover by degrading proline-containing dipeptides but its specific functional relevance in AT is unknown. Here we show that in human and mouse obesity, PEPD expression and activity decrease in AT, and PEPD is released into the systemic circulation, which promotes fibrosis and AT IR. Loss of the enzymatic function of PEPD by genetic ablation or pharmacological inhibition causes AT fibrosis in mice. In addition to its intracellular enzymatic role, secreted extracellular PEPD protein enhances macrophage and adipocyte fibro-inflammatory responses via EGFR signalling, thereby promoting AT fibrosis and IR. We further show that decreased prolidase activity is coupled with increased systemic levels of PEPD that act as a pathogenic trigger of AT fibrosis and IR. Thus, PEPD produced by macrophages might serve as a biomarker of AT fibro-inflammation and could represent a therapeutic target for AT fibrosis and obesity-associated IR and type 2 diabetes.

Abstract
Burns to the palmar aspect of the hand are prevalent in young children. The development of scar tissue across the flexor surface of the hand combined with the years of growth ahead may result in considerable complications. This study was undertaken to describe outcomes of early and intensive use of a palm and digit extension orthosis with the elbow immobilized at 90° flexion following a palmar hand burn. A retrospective review of 107 children (mean age 18 months [SD 10]) treated at a statewide Pediatric Burns Unit from 2012 to 2016 was performed. Three children (3%) developed contracture during the 24-month study follow-up period. The other 104 children (97%) had full ROM at 24 months or at either the point of discharge or loss to follow-up. Early signs of contracture, defined as loss of full movement or significant banding, developed in 26 children (24%) in the first 9 months after burn. With intensive physiotherapy, 23 children regained full movement by 12 months after burn. Children who did not achieve complete wound healing at 1 month after burn and children with hypertrophic scarring at 2 months after burn were significantly more represented among cases of early signs of contracture (P = .013). When undertaken with regular clinical review, early and intensive use of a palm and digit extension orthosis can maintain full extension of the palm and digits in children after palmar burn.

Abstract
Evidence of personal and health-system benefits of pulmonary rehabilitation are undeniable. However, the capacity of traditional centre-based models to both reach and appeal to the intended population of people living with chronic obstructive pulmonary disease (COPD) remains difficult. It is well established that issues with access, suitability, referral, uptake, and attrition exist. Consequently, considerable energy has been invested into exploring innovative alternative modes of rehabilitation in an effort to increase the awareness and appeal, and expand the availability of pulmonary rehabilitation. The process of 'thinking differently' and 'pushing the boundaries' of clinical practice is underway, particularly in the United Kingdom and Australia, where new models of pulmonary rehabilitation are being evaluated. The number one priority is reaching the population of people with COPD and ensuring they are referred to rehabilitation services. Active case-finding in primary care, inviting health professionals and health consumers to pulmonary rehabilitation programs to increase understanding and awareness, and utilizing peer support via patient success stories, are just a few suggestions for increasing awareness of pulmonary rehabilitation. Once referred, engaging the population to complete a program is the next challenge. Marketing, patient co-design, alternative rehabilitation settings and modes of exercise training, use of technology, and focusing on modes which provide patient enjoyment and choice are all potential strategies to target in an effort to broaden the appeal and reduce the high attrition rate of traditional centre-based pulmonary rehabilitation programs. Reaching and engaging the target population in pulmonary rehabilitation is an important first step in people with COPD achieving successful outcomes from rehabilitation.

Abstract
AIMS Patients with chemotherapy-refractory colorectal cancer liver metastases have limited therapeutic options. Selective internal radiation therapy (SIRT) delivers yttrium 90 microspheres as a minimally invasive procedure. This prospective, single-arm, observational, service-evaluation study was part of National Health Service England Commissioning through Evaluation. METHODS Patients eligible for treatment had histologically confirmed carcinoma with liver-only/liver-dominant metastases with clinical progression during or following oxaliplatin-based and irinotecan-based chemotherapy. All patients received SIRT plus standard of care. The primary outcome was overall survival; secondary outcomes included safety, progression-free survival (PFS) and liver-specific PFS (LPFS). RESULTS Between December 2013 and March 2017, 399 patients were treated in 10 centres with a median follow-up of 14.3 months (95% confidence interval 9.2-19.4). The median overall survival was 7.6 months (95% confidence interval 6.9-8.3). The median PFS and LPFS were 3.0 months (95% confidence interval 2.8-3.1) and 3.7 months (95% confidence interval 3.2-4.3), respectively. During the follow-up period, 143 patients experienced an adverse event and 8% of the events were grade 3. CONCLUSION Survival estimates from this pragmatic study show clinical outcomes attainable in the National Health Service comparable with previously published data. This study shows the value of a registry-based commissioning model to aid national commissioning decisions for highly specialist cancer treatments.

Abstract
QUESTIONS What is the level of technology engagement by people attending pulmonary rehabilitation? Are participant demographics and level of technology engagement associated with willingness to use telerehabilitation? DESIGN A cross-sectional, multicentre study involving quantitative survey analysis. PARTICIPANTS Convenience sample of people with chronic respiratory disease attending a pulmonary rehabilitation program, maintenance exercise class or support group. OUTCOME MEASURES The survey assessed the participants' level of technology engagement (access to and use of devices), self-rated skill competence, access to online health information and willingness to use telerehabilitation. RESULTS Among the 254 people who were invited, all agreed to complete the survey (100% response rate). Among these 254 respondents, 41% were male, the mean age was 73 years (SD 10), and the mean forced expiratory volume in 1second (FEV1) was 59% predicted (SD 23). Ninety-two percent (n=233) of participants accessed at least one technological device, of whom 85% (n=198) reported regularly using mobile phones and 70% (n=164) regularly used a computer or tablet. Fifty-seven percent (n=144) of participants self-rated their technology skill competence as good and 60% (n=153) of all participants were willing to use telerehabilitation. The multivariate regression model found regular computer use (OR 3.14, 95% CI 1.72 to 5.71) and regular mobile phone use (OR 2.83, 95% CI 1.32 to 6.09) were most associated with a willingness to use telerehabilitation. CONCLUSION People attending metropolitan pulmonary rehabilitation, maintenance exercise classes and support groups had substantial technology engagement, with high device access and use, and good self-rated technology competence. The majority of participants were willing to use telerehabilitation, especially if they were regular users of technology devices.

Abstract
Background There is emerging research detailing the relationship between balance/gait/falls and cognition. Imaging studies also suggest a link between structural and functional changes in the frontal lobe (a region commonly associated with cognitive function) and mobility. People with Parkinson’s disease have important changes in cognitive function that may impact rehabilitation efficacy. Our underlying hypothesis is that cognitive function and frontal lobe connections with the basal ganglia and brainstem posture/locomotor centers are responsible for postural deficits in people with Parkinson’s disease and play a role in rehabilitation efficacy. The purpose of this study is to 1) determine if people with Parkinson’s disease can improve mobility and/or cognition after partaking in a cognitively challenging mobility exercise program and 2) determine if cognition and brain circuitry deficits predict responsiveness to exercise rehabilitation. Methods/Design This study is a randomized cross-over controlled intervention to take place at a University Balance Disorders Laboratory. The study participants will be people with Parkinson’s disease who meet inclusion criteria for the study. The intervention will be 6 weeks of group exercise (case) and 6 weeks of group education (control). The exercise is a cognitively challenging program based on the Agility Boot Camp for people with PD. The education program is a 6-week program to teach people how to better live with a chronic disease. The primary outcome measure is the MiniBESTest and the secondary outcomes are measures of mobility, cognition and neural imaging. Discussion The results from this study will further our understanding of the relationship between cognition and mobility with a focus on brain circuitry as it relates to rehabilitation potential. Trial registration This trial is registered at clinical trials.gov (NCT02231073).

Abstract
Huntington's disease (HD) is a neurodegenerative genetic condition for which a predictive genetic test by mutation analysis has been available since 1993. However, whilst revealing the future presence of the disease, testing may have an adverse psychological impact given that the disease is progressive, incurable and ultimately fatal. This review seeks to systematically explore the psychological impact of genetic testing for individuals undergoing pre-symptomatic mutation analysis. Three databases (Medline, PsycInfo and Scopus) were interrogated for studies utilising standardised measures to assess psychological impact following predictive genetic testing for HD. From 100 papers initially identified, eight articles were eligible for inclusion. Psychological impact of predictive genetic testing was not found to be associated with test result. No detrimental effect of predictive genetic testing on non-carriers was found, although the process was not found to be psychologically neutral. Fluctuation in levels of distress was found over time for carriers and non-carriers alike. Methodological weaknesses of published literature were identified, notably the needs of individuals not requesting genetic testing, as well as inadequate support for individuals registering elevated distress and declining post-test follow-up. Further assessment of these vulnerable individuals is warranted to establish the extent and type of future psychological support.

Abstract
Many genes express multiple transcript isoforms generated by alternative splicing of mRNA. Using real-time PCR, it is straightforward to determine the relative expression level of each isoform independently. However, it is less trivial to determine the relative proportions of different isoforms in a cDNA sample. The relative proportions of different isoforms can be important, as a small change in a highly abundant transcript may be more relevant than a large change in a minimally expressed transcript. Currently, determining the relative proportions of isoforms requires the construction of a standard curve using recombinant plasmid DNA or genomic DNA. As recombinant or genomic DNA standards often amplify with different efficiencies to cDNA samples, they may give under- or overestimations of isoform abundances. The method described in this article uses a titration curve generated from the same cDNA samples measured in the experiment. By using samples with different levels of separate isoforms, it is possible to derive linear equations which, when solved, allow the determination of the proportion of each isoform within the samples under study.

Abstract
An audit of triage was conducted between June and September 2003 in a district general hospital genitourinary medicine department to evaluate the appropriateness of triage criteria to identify those who require urgent intervention. We selected gonorrhoea (B1), chlamydia (C4a), gential herpes (C10a/b) and epidemiological treatment of contacts of B1 or C4a (C4e/B4) as conditions requiring urgent intervention. Eighty-eight percent met one or more of the criteria and were offered urgent appointments and 69% who did not meet the criteria were offered routine appointments. The incidences of B1, C4a, C10a/b and C4e/B4 were 26.5%, 21.2%, 16.8% and 8% respectively in the urgent group compared with corresponding incidences of 4.4% and 16.2% respectively in the routine group. No cases of C10a/b or C4e/B4 were seen in the latter group. Although triage criteria did not identify asymptomatic infections, efficient contact tracing will improve detection of asymptomatic carriers of infections and should be encouraged. The outcome of the audit informed modifications to the criteria and reinforced the need for staff training in triage. In the United Kingdom, genitourinary medicine must be urgently prioritized and invested in, to improve access to all who need to be seen within 48 h of contacting the service.

Abstract
In mouse the melanocortin 5 receptor is known to regulate sebaceous gland function. To clarify its role in man, we have studied melanocortin 5 receptor expression in skin, and allelic variation at the melanocortin 5 receptor locus in diverse human populations and candidate disease groups. Melanocortin 5 receptor protein and mRNA expression were studied by immunohistochemistry and reverse transcriptase polymerase chain reaction. Melanocortin 5 receptor mRNA was detected in normal skin and cultured keratinocytes but not in cultured fibroblasts or melanocytes. Immunohistochemistry revealed melanocortin 5 receptor immunoreactivity in the epithelium and appendages, including the sebaceous gland, eccrine glands, and apocrine glands, as well as low level expression in the interfollciular epidermis. In order to screen for genetic diversity in the melanocortin 5 receptor that might be useful for allelic association studies we sequenced the entire melanocortin 5 receptor coding region in a range of human populations. One nonsynonymous change (Phe209Leu) and four synonymous changes (Ala81Ala, Asp108Asp, Ser125Ser, and Thr248Thr) were identified. Similar results were found in each of the populations except for the Inuit in which only the Asp108Asp variant was seen. The apparent "global distribution" of melanocortin 5 receptor variants may indicate that they are old in evolutionary terms. Variation of melanocortin 5 receptor was examined in patients with acne (n = 21), hidradenitis supprativa (n = 4), and sebaceous gland lesions comprising sebaceous nevi, adenomas, and hyperplasia (n = 13). No additional mutations were found. In order to determine the functional status of the Phe209Leu change, increase in cAMP in response to stimulation with alpha-melanocyte-stimulating hormone was measured in HEK-293 cells transfected with either wild-type or the Phe209Leu variant. The variant melanocortin 5 receptor was shown to act in a concentration-dependent manner, which did not differ from that of wild type. We have therefore found no evidence of a causative role for melanocortin 5 receptor in sebaceous gland dysfunction, and in the absence of any association between variation at the locus and disease group, the pathophysiologic role of the melanocortin 5 receptor in man requires further study.

Abstract
We performed a systematic mapping of interaction domains on COP I subunits to gain novel insights into the architecture of coatomer. Using the two-hybrid system, we characterize the domain structure of the alpha-, beta'-, epsilon-COP and beta-, gamma-, delta-, zeta-COP coatomer subcomplexes and identify links between them that contribute to coatomer integrity. Our results demonstrate that the domain organization of the beta-, gamma-, delta-, zeta-COP subcomplex and AP adaptor complexes is related. Through in vivo analysis of alpha-COP truncation mutants, we characterize distinct functional domains on alpha-COP. Its N-terminal WD40 domain is dispensable for yeast cell viability and overall coatomer function, but is required for KKXX-dependent trafficking. The last approximately 170 amino acids of alpha-COP are also non-essential for cell viability, but required for epsilon-COP incorporation into coatomer and maintainance of normal epsilon-COP levels. Further, we demonstrate novel direct interactions of coatomer subunits with regulatory proteins: beta'- and gamma-COP interact with the ARF-GTP-activating protein (GAP) Glo3p, but not Gcs1p, and beta- and epsilon-COP interact with ARF-GTP. Glo3p also interacts with intact coatomer in vitro.

Abstract
Rheumatoid arthritis (RA) is a common disease of unknown aetiology which usually causes progressive destruction of the joints. Familial aggregation, twin studies and segregation analyses suggest that there is a genetic component to RA and the HLA-DRB1 locus in the major histocompatibility complex on chromosome 6 has been shown to be linked to, and associated with, RA susceptibility. It is likely that other genes with weaker effects are also involved, which may be difficult to detect using conventional parametric and non-parametric linkage methods. We have implemented the combined sib-TDT and TDT, in addition to parametric and non-parametric linkage methods, to investigate the candidate genes of the interleukin-1 (IL-1) gene cluster on chromosome region 2q13, since IL-1 is an important cytokine in the control of the inflammatory response that is central to RA pathology. Several tightly linked IL-1 cluster markers yielded suggestive evidence for linkage in the combined TDT in those families in which affected siblings did not share two HLA-DRB1 alleles identical by descent. The evidence was significant in those with severe disease, as assessed by the presence of bone erosions. In contrast, there was no evidence of linkage using non-parametric linkage analysis, but parametric analysis revealed weak evidence of linkage when marker-trait disequilibrium was incorporated into the analysis. The data provide preliminary evidence for linkage of genes of the IL-1 cluster to RA and suggest a possible role for this region in severe erosive disease.

Abstract
The family of interleukin-1 receptor-like genes currently has six known members. We have constructed a contig of 10 overlapping human PAC clones that covers 530 kb and includes five of the six family members. The termini of the contig were mapped to the interval between D2S373 and D2S176 (chromosome 2q12) by radiation hybrid mapping. The contig contains the genes (cen --> tel), in the order given, for the type II interleukin-1 (IL-1) receptor (IL1R2), the type I IL-1 receptor (IL1R1), the IL-1 receptor-related protein 2 (IL1RL2), T1/ST2/fit-1 (IL1RL1), and the IL-1 receptor-related protein 1, which has recently been shown to be a component of the IL-18 receptor (IL18R1). We show that all the genes are transcribed in the same direction, with IL1R2 being transcribed toward the cluster. The only known family member that is absent from the human contig is the IL-1 receptor accessory protein gene (IL1RAP), which maps to 3q28.

Abstract
In the transcriptionally inert maturing oocyte and early embryo, control of gene expression is largely mediated by regulated changes in translational activity of maternal mRNAs. Some mRNAs are activated in response to poly(A) tail lengthening; in other cases activation results from de-repression of the inactive or masked mRNA. The 3' UTR cis-acting elements that direct these changes are defined, principally in Xenopus and mouse, and the study of their trans-acting binding factors is just beginning to shed light on the mechanism and regulation of cytoplasmic polyadenylation and translational masking. In the marine invertebrate, Spisula solidissima, the timing of activation of three abundant mRNAs (encoding cyclin A and B and the small subunit of ribonucleotide reductase, RR) in fertilized oocytes correlates with their cytoplasmic polyadenylation. However, in vitro, mRNA-specific unmasking occurs in the absence of polyadenylation. In Walker et al. (in this issue) we showed that p82, a protein defined as selectively binding the 3' UTR masking elements, is a homolog of Xenopus CPEB (cytoplasmic polyadenylation element binding protein). In functional studies reported here, the elements that support polyadenylation in clam egg lysates include multiple U-rich CPE-like motifs as well as the nuclear polyadenylation signal AAUAAA. This represents the first detailed analysis of invertebrate cis-acting cytoplasmic polyadenylation signals. Polyadenylation activity correlates with p82 binding in wild-type and CPE-mutant RR 3' UTR RNAs. Moreover, since anti-p82 antibodies specifically neutralize polyadenylation in egg lysates, we conclude that clam p82 is a functional homolog of Xenopus CPEB, and plays a positive role in polyadenylation. Anti-p82 antibodies also result in specific translational activation of masked mRNAs in oocyte lysates, lending support to our original model of clam p82 as a translational repressor. We propose therefore that clam p82/CPEB has dual functions in masking and cytoplasmic polyadenylation.

Abstract
A potent anti-prolactin drug, cabergoline, administered orally for five days, was clinically successful in treating three different clinical manifestations of pseudopregnancy in referred bitches. The clinical conditions treated were categorised as standard pseudopregnant bitches (n = 8), those previously unsuccessfully treated with hormones (n = 10) and those which had behavioural pseudopregnancy following ovariohysterectomy (n = 8). The number of bitches whose owners reported a 'good' response was seven out of eight, six out of 10 and six out of eight, respectively. There were very few side effects in that only one bitch vomited following treatment. The clinical response did not necessarily appear to be related to an alteration in circulating prolactin concentrations, suggesting that the drug may have a direct effect on the tissues as well as in most cases reducing the plasma prolactin concentrations.

Abstract
During meiotic maturation or after fertilization of invertebrate and vertebrate oocytes, many of the quiescent stored mRNAs are recruited into polysomes. In the clam, Spisula solidissima, such masked messages include the abundant mRNAs encoding cyclin A and the small subunit of ribonucleotide reductase. We have previously shown that mRNA-specific unmasking of these two messages can be achieved in vitro, in oocyte cell-free extracts, by the addition of antisense RNAs corresponding to a fairly short (130-140 nucleotides) segment in their cognate 3' untranslated regions. We postulated that the antisense RNAs prevented the binding of a masking repressor protein (Standart et al., 1990). Here we report UV-crosslinking and gel retardation studies which show that the masking portions of the translationally regulated mRNAs bind an oocyte protein of 82 kDa (p82), which is phosphorylated after fertilization. This modification was accompanied by altered RNP complex formation in gel retardation assays. These changes presumably reflect the activation of translation of the masked mRNAs. The role of p82 phosphorylation in maternal mRNA unmasking was assessed in a novel in vitro activation system developed from clam oocytes, based upon the natural rise in pH which accompanies fertilization. Concomitant with mRNA unmasking, several kinases, including cdc2 and MAP kinases were activated in this system, as was p82 phosphorylation. Inhibitors of serine/threonine kinases, including 6-DMAP, staurosporine, and H7 inhibited p82 phosphorylation, whereas inhibitors of tyrosine kinases, protein kinase C, cAMP-dependent protein kinase, and p70s6k did not prevent this modification. A specific inhibitor of cdc2 kinase, p27Kip1, prevented p82 phosphorylation and translational activation, strongly suggesting that p82 modification is required for unmasking.

Abstract
Trials over 2 years were undertaken to determine the effect of cold disinfestation at 1�C on the internal and external quality of Washington navel oranges. Chilling injury in the form of cold scald and rind pitting were significantly increased by cold disinfestation. The incidence and severity of chilling injury was low (maximum 7% of fruit rejected due to chilling injury), indicating that 16 days storage at 1�C will result in minimal fruit loss due to chilling injury. Extended storage at 10�C after cold disinfestation at 1�C for 16 days increased the severity of the chilling injury symptoms observed. The incidence of postharvest fungal breakdown was high in the second year of the trial and red Altemaria spot was high in the first year. Oleocellosis was present in almost all fruit tested and severe in 75% of the fruit. The overall external quality of the fruit was highly influenced by grower but no correlation between fruit quality and specific management practices could be made. These results indicate that 'in transit' cold disinfestation would be a feasible treatment for export Washington navel oranges but with provisos: that total transit time is kept to a minimum, and that care is taken to minimise postharvest fungal breakdown and incidence of oleocellosis.

Abstract
During meiotic maturation of Spisula oocytes, maternal mRNAs undergo changes in translation and in the length of their poly(A) tails. In general, those mRNAs that are translationally activated, i.e., unmasked, become polyadenylated, while deactivated mRNAs lose their poly(A) tails. The activated class of mRNAs encode ribonucleotide reductase, cyclins A and B and histone H3, while the proteins that stop being made include tubulin and actin. Previously, we demonstrated that mRNA-specific unmasking can be brought about in vitro by preventing the interaction of protein(s) with central portions of the 3' noncoding regions (masking regions) of ribonucleotide reductase and cyclin A mRNAs. In this report, we show that clam egg extracts are capable of sequence-specific polyadenylation of added RNAs since the 3' untranslated regions (UTRs) of ribonucleotide reductase and histone H3 mRNAs are polyadenylated, while that of actin mRNA is not. In contrast, oocyte extracts, as in vivo, are essentially devoid of polyadenylation activity. We present an initial characterisation of the cis-acting sequences in the 3' UTR of ribonucleotide reductase mRNA required for polyadenylation. The results suggest that the sequences for cytoplasmic polyadenylation are more complex and extensive than those determined in vertebrates and that they may partly overlap with the masking regions.

Abstract
The computed tomography scans of both the injured and the normal wrists of nine patients with a scaphoid nonunion of 5 to 120 months' duration were used to create three-dimensional computer models. When the computer images of the normal and the contralateral fractured scaphoids were superimposed, it was possible to calculate the volume of bone that was lost as a result of the injury and its failure to heal, as well as the angular relationship of the fracture components to one another. The amount of the scaphoid bone that was lost varied from 6% to 15% of bone volume and did not show a linear correlation with the duration of the nonunion. The configuration of the missing bone was consistent and exhibited a prismatic shape whose base is quadrilateral and faces palmarly. The proximal scaphoid fracture component is extended, radially deviated, and supinated in relation to its distal fracture component. The consistent fracture deformity and the configuration of the bony defect in the scaphoid waist nonunions should be helpful in the understanding and treatment of the condition.

Abstract
Clam oocytes display a striking difference in the pattern of protein synthesis on fertilization, which is maintained when cell-free extracts are assayed in the rabbit reticulocyte lysate. The mRNAs encoding ribonucleotide reductase and cyclin A (the major masked messages in the oocyte extracts) can be translationally activated by gel filtration in 0.5 M KCl, presumably by removal of repressor protein(s). When synthetic RNAs corresponding to different segments of ribonucleotide reductase and cyclin A mRNAs were added to oocyte extracts in 0.5 M KCl in a "competitive unmasking" assay, specific and complete unmasking of these mRNAs occurred on addition of antisense 3'-noncoding transcripts. The unmasking region in ribonucleotide reductase mRNA maps to a region of 134 nucleotides centered one-third of the way down the 3'-noncoding region.

Abstract
The computed carpal models from digital computed tomography (CT) data obtained in this study compare favorably to natural anatomy. A new application of algebraic analysis of this data provides mathematical markers from which to calculate the position and orientation of each carpal bone. When the origin of the spatial coordinates of a carpal bone is transferred to the centroid of the bone, the data can be treated as three-dimensional pattern vectors describing its surface. It is then possible to calculate vectors that are the principal axes of the geometry. These axes provided references that were used to calculate position and orientation of the carpal bones in three wrist specimens. Comparisons of volumes, surface areas, and sizes and proportions of five computed images of each carpal bone from two of these wrists demonstrate the reliability of the technique. The analysis of CT scans of ceramics with known boundaries allows an estimation of its accuracy. The technique is well suited to the future study of normal wrist kinematics and pathological conditions.

Abstract
The effects of three oil spill chemicals (Corexit 9600, 9550, and 7664) on cuticular structure and function in the sandbar willow Salix interior were assessed from direct observations of the leaf surface, using scanning electron microscopy, and from measurements of water loss through transpiration. Rates of CO2 exchange in the light and dark were also measured. Although the Corexits coated the leaf surfaces, wax plates (crystals) associated with the cuticle were not visibly altered. The dispersants did not increase rates of evaporative water loss. Rates of net CO2 assimilation in the light, however, were reduced by 54, 63, and 94% 1 h after contact with Corexit 7664, 9550, and 9600, respectively. Measurements of surface contact angles and observations on the movement of dye–dispersant mixtures indicated that the rapid inhibition of CO2 assimilation resulted from the spontaneous infiltration of stomata by the dispersants and direct action on the internal tissues of the leaf. Rates of dark respiration were initially unaffected but decreased after 1 day. Further reductions in rates of CO2 exchange were observed over the first 4 days (associated with extensive leaf chlorosis and necrosis); then the rates increased following new tissue growth. Although the dispersants are potent contact poisons, damage to the protective cuticle in Salix interior does not appear to be a major contributing factor to their toxicity.

Abstract
A sensitive method for the quantitation of IgG on platelets had not been demonstrated until 1975, when Dixon, Rosse, and Ebbert described a quantitative antiglobulin consumption test useful in detecting platelet associated IgG (N Engl J Med 292:230, 1975). A modification of that technique has rendered the assay reproducible and removed the need for daily repetition of a standard IgG titration curve for quantitation. This modification utilizes 1-ethyl-3-3(dimethylaminopropyl)carbodiimide HCl (ECDI) (Sigma, E-7750), in place of chromic chloride, as a coupling agent for attaching IgG (Miles 64-145) to sheep cells (SRC), used as indicator cells. The ECDI consistently couples IgG to SRC and does not subject the SRC to sporadic spontaneous lysis, as does chromic chloride. This modification permits the detection of IgG on platelets (Direct Test), or in sera (Indirect Test) by incubation of a washed platelet pool with sera in vitro, and testing as in the Direct Test. Normal values of 0.01-1.56 and 0.14-1.6 femtograms (F) per platelet have been obtained for the Direct and Indirect Tests, respectively. In six cases of suspected ITP, values ranged 12.0-221.0 F and 2.9-37.6 F for the Direct and Indirect Tests, respectively. In conclusion, in disease states or other abnormal situations, quantities of IgG can be detected that are not usually present on the platelets of normal subjects.
