Abstract
Previous studies have failed to show an effect of episodic future thinking (EFT) on children's delay of gratification (DoG), contrasting strikingly with adult findings. Recent findings from a sample of 8-11-year-old children by Canning et al. (J. Exp. Child Psychol., 228, 2023, 105618) indicate that EFT cueing is not effective compared to a no-cue control even when it is reward related. Canning et al. suggest children's DoG performance, unlike that of adults, may be negatively affected by the cognitive load of cueing, but this leaves unexplained why EFT reward-related cueing produced significantly better performance than cueing that did not involve EFT in their study. The current study attempted to further delineate the importance of linking future thinking cues to rewards. A reward-related EFT condition was compared to a reward-unrelated EFT condition and a no-cue control on a delay choice task. No significant differences were observed between the three conditions. This suggests that even reward-related future thinking is ineffective at improving children's delayed gratification. Further research is needed to determine why children struggle to benefit from EFT cues.

Abstract
Encoding and recalling spoken instructions is subject to working memory capacity limits. Previous research suggests action-based encoding facilitates instruction recall, but has not directly compared benefits across different types of action-based techniques. The current study addressed this in two experiments with young adults. In Experiment 1, participants listened to instructional sequences containing four action-object pairs, and encoded these instructions using either a motor imagery or verbal rehearsal technique, followed by recall via oral repetition or enactment. Memory for instructions was better when participants used a motor imagery technique during encoding, and when recalling the instructions by enactment. The advantage of using a motor imagery technique was present in both verbal and enacted recall. In Experiment 2, participants encoded spoken instructions whilst implementing one of four techniques (verbal rehearsal, motor imagery, observation of others' actions or self-enactment), and then recalled the instructions by oral repetition or enactment. For both verbal and enacted recall, memory for instructions was least accurate in the rehearsal condition, while the other encoding conditions did not differ from each other. These novel findings indicate similar benefits of imagining, observation and execution of actions in encoding spoken instructions, and enrich current understanding of action-based benefits in working memory.

Abstract
Mind wandering occurs when attention becomes disengaged from the here-and-now and directed toward internally generated thoughts; this is often associated with poorer performance on educationally significant tasks. In this study, 8- to 9-year-old children (N = 60) listened to audio stories embedded with intermittent thought probes that were used to determine if participants' thoughts were on or off task. The key objective was to explore the impact of probe-caught mind wandering on both immediate and delayed memory retention. Children reported being off task approximately 24% of the time. Most inattention episodes were classified as task-unrelated thoughts (i.e., 'pure' instances of mind wandering, 9%) or attentional failures due to distractions (9%). Higher frequency of mind wandering was strongly associated with poorer memory recall, and task-unrelated thoughts strongly predicted how well children could recall components of the audio story both immediately after the task and after a 1-week delay. This study is the first to demonstrate the impact of mind wandering on delayed memory retention in children. Results suggest that exploring mind wandering in the foundational years of schooling could provide the necessary empirical foundation for the development of practical interventions geared toward detecting and refocusing lapses of attention in educational contexts.

Abstract
Despite being implicated in a wide range of psychological and behavioral phenomena, relief remains poorly understood from the perspective of psychological science. What complicates the study of relief is that people seem to use the term to describe an emotion that occurs in two distinct situations: when an unpleasant episode is over, or upon realizing that an outcome could have been worse. This study constitutes a detailed empirical investigation of people's reports of everyday episodes of relief. A set of four studies collected a large corpus (N = 1,835) of first-person reports of real-life episodes of relief and examined people's judgments about the antecedents of relief, its relation to counterfactual thoughts, and its subsequent effects on decision making. Some participants described relief experiences that had either purely temporal or purely counterfactual precursors. Nevertheless, the findings indicated that the prototypical instance of relief appears to be one in which both these elements are present. The results also suggest that, although relief is frequently experienced in situations in which people are not responsible for the relief-inducing event, nevertheless they typically report that the experience had a positive impact on subsequent decision making.

Abstract
How working memory supports dual-task performance is the focus of a long-standing debate. Most previous research on this topic has focused on participant performance data. In three experiments, we investigated whether changes in participant-reported strategies across single- and dual-task conditions might help resolve this debate by offering new insights that lead to fruitful integration of theories rather than perpetuating debate by attempting to identify which theory best fits the data. Results indicated that articulatory suppression was associated with reduced reports of the use of rehearsal and clustering strategies but to an increase of the reported use of a visual strategy. Elaboration and clustering strategies were reported less for memory under dual task compared with single task. Under both dual task and articulatory suppression, more participants reported attempting to remember fewer memory items than were presented (memory reduction strategy). For arithmetic verification, articulatory suppression and dual task resulted in a reduction in reports of a counting strategy and an increase in reports of a retrieval strategy for arithmetic knowledge. It is argued that experimenters should not assume that participants perform the same task in the same way under different experimental conditions and that carefulty investigation of how participants change their strategies in response to changes in experimental conditions has considerable potential for resolving theoretical challenges. It is argued further that this approach points toward the value of attempting to integrate rather than proliferate theories of working memory.

Abstract
OBJECTIVE Studies have shown variable memory performance in patients with behavioral variant frontotemporal dementia (bvFTD). Our study investigated whether this variability is due to the admixture of patients with true bvFTD and phenocopy patients. We also sought to compare performance of patients with bvFTD and patients with Alzheimer disease (AD). METHODS We analyzed neuropsychological memory performance in patients with a clinical diagnosis of bvFTD divided into those who progressed (n = 50) and those who remained stable (n = 39), patients with AD (n = 64), and healthy controls (n = 64). RESULTS Patients with progressive bvFTD were impaired on most memory tests to a similar level to that of patients with early AD. Findings from a subset of patients with progressive bvFTD with confirmed FTLD pathology (n = 10) corroborated these findings. By contrast, patients with phenocopy bvFTD performed significantly better than progressors and patients with AD. Logistic regression revealed that patients with bvFTD can be distinguished to a high degree (85%) on the immediate recall score of a word list learning test (Rey Auditory Verbal Learning Test). CONCLUSIONS Our results provide evidence for an underlying memory deficit in "real" or progressive behavioral variant frontotemporal dementia (bvFTD) similar to Alzheimer disease, though the groups differ in orientation scores, with patients with bvFTD being intact. Exclusion solely based on impaired neuropsychological memory performance can potentially lead to an underdiagnosis of FTD.

Abstract
This contribution documents the satellite data archives, data processing methods and temporal Fourier analysis (TFA) techniques used to create the remotely sensed datasets on the DVD distributed with this volume. The aim is to provide a detailed reference guide to the genesis of the data, rather than a standard review. These remotely sensed data cover the entire globe at either 1 x 1 or 8 x 8 km spatial resolution. We briefly evaluate the relationships between the 1 x 1 and 8 x 8 km global TFA products to explore their inter-compatibility. The 8 x 8 km TFA surfaces are used in the mapping procedures detailed in the subsequent disease mapping reviews, since the 1 x 1 km products have been validated less widely. Details are also provided on additional, current and planned sensors that should be able to provide continuity with these environmental variable surfaces, as well as other sources of global data that may be used for mapping infectious disease.

Abstract
Scale and uncertainty are important issues for the global prediction of disease. Disease mapping over the entire surface of the Earth usually involves the use of remotely sensed imagery to provide environmental covariates of disease risk or disease vector density. It further implies that the spatial resolution of such imagery is relatively coarse (e.g., 8 or 1km). Use of a coarse spatial resolution limits the information that can be extracted from imagery and has important effects on the results of epidemiological analyses. This paper discusses geostatistical models for (i) characterizing the scale(s) of spatial variation in data and (ii) changing the scale of measurement of both the data and the geostatistical model. Uncertainty is introduced, highlighting the fact that most epidemiologists are interested in accuracy, aspects of which can be estimated with measurable quantities. This paper emphasizes the distinction between data- and model-based methods of accuracy assessment and gives examples of both. The key problem of validating global maps is considered.

Abstract
The objective was to develop, pretest and validate a disease-specific quality of life questionnaire for potentially curable patients with esophageal carcinoma, for use with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) in order to assess the quality of life associated with the various treatment modalities available for this disease. Questionnaire development phase Patients were enrolled in three centres. Literature reviews, patients, family members, and health care professionals generated 195 items: symptoms (55); emotions (53); physical functioning (17); activities of daily living (ADL) (48); and leisure/social (22). Thirty-eight patients identified items of importance and assigned importance ratings on a 5-point Likert scale. Impact scores were calculated as frequency times mean item importance. Item impact scores<20/100 were excluded. Pearson's correlation co-efficients compared domains with the Medical Outcomes Study SF-20 (MOS SF-20). Fifteen items remained. Questionnaire validation phase EORTC QLQ-C30, Esophageal Quality of Life Questionnaire (EQOL), MOS SF-36 and a Global Rating of Change Questionnaire were completed at baseline, 1 week after baseline but prior to any treatment, 1 month, 3 months, and 6 months after treatment began. Reliability was assessed using paired samples correlations. Responsiveness was assessed between mean scores of changed and unchanged patients, and a responsiveness index was calculated. The MOS SF-36 was used for criterion validity. Construct validity included four a priori predictions. Sixty-five patients were enrolled in four centres in the validation phase. Paired samples correlations were high for all domains (0.749-0.889) indicating good reliability. Symptom, physical function and social domains were responsive to change at all time intervals (P<0.05). Emotional function was responsive at 1 and 3 months, activities of daily living (ADLs) at 1 and 6 months. Magnitude of change was significant when direction of change was stated. Between better and worse, magnitude of change was significant in all domains except at 6 months in symptoms, emotional and physical domains. The minimal clinically important difference was consistently around 0.5 for all domains. Minimal, moderate and large effect ranges were established. Only 2/16 time intervals had poor correlations with the SF-36, establishing criterion validity. Of the four a priori predictions for construct validity, only the second part of one prediction, in the emotional function domain, was not confirmed. We have developed a 15-item questionnaire (EQOL) which has good reliability, responsiveness and validity and is now in use in studies in Canadian centres with the EORTC QLQ-C30.

Abstract
Yellow fever has been subjected to partial control for decades, but there are signs that case numbers are now increasing globally, with the risk of local epidemic outbreaks. Dengue case numbers have also increased dramatically during the past 40 years and different serotypes have invaded new geographical areas. Despite the temporal changes in these closely related diseases, and their enormous public health impact, few attempts have been made to collect a comprehensive dataset of their spatial and temporal distributions. For this review, records of the occurrence of both diseases during the 20th century have been collected together and are used to define their climatic limits using remotely sensed satellite data within a discriminant analytical model framework. The resulting risk maps for these two diseases identify their different environmental requirements, and throw some light on their potential for co-occurrence in Africa and South East Asia.

Abstract
The cholinergic system has been implicated in the development of autism on the basis of neuronal nicotinic acetylcholine receptor (nAChR) losses in cerebral and cerebellar cortex. In the present study, the first to explore nAChRs in the thalamus in autism, alpha4, alpha7 and beta2 nAChR subunit expression in thalamic nuclei of adult individuals with autism (n=3) and age-matched control cases (n=3) was investigated using immunochemical methods. Loss of alpha7- and beta2- (but not alpha4-) immunoreactive neurons occurred in the paraventricular nucleus (PV) and nucleus reuniens in autism. Preliminary results indicated glutamic acid decarboxylase immunoreactivity occurred at a low level in PV, co-expressed with alpha7 in normal and autistic cases and was not reduced in autism. This suggested loss of neuronal alpha7 in autism is not caused by loss of GABAergic neurons. These findings indicate nicotinic abnormalities that occur in the thalamus in autism which may contribute to sensory or attentional deficits.

Abstract
We obtain the nucleation rate of critical droplets for an elastic string moving in a phi(6) local potential and subject to noise and damping forces. The critical droplet is a bound soliton-antisoliton pair that carries a section of the string out of the metastable central minimum into one of the stable side minima. The frequencies of small oscillations about the critical droplet are obtained from a Heun equation. We solve the Fokker-Planck equation for the phase-space probability density by projecting it onto the eigenfunction basis obtained from the Heun equation. We employ Farkas' "flux-overpopulation" method to obtain boundary conditions for solving the Fokker-Planck equation; these restrict the validity of our solution to the moderate to heavy damping regime. We present results for the rate as a function of temperature, well depth, and damping.

Abstract
The larval form of the fox tapeworm Echinococcus multilocularis can cause a potentially fatal liver infection in human hosts. Globally rare, the disease has a high prevalence focus in western China. Recent research has linked landscape to the presence and prevalence of the disease. This paper discusses the epidemiology of E. multilocularis in terms of landscape and disease transmission ecology. Landscape form was defined using satellite imagery to create a land cover classification for a study site in Zhang County (Gansu Province, China). Following the analysis of many landscape metrics, mean shape index was found to be related to the prevalence of infection for 31 villages in 1975 and 1997, at two spatial intervals, suggesting that habitat form is a correlate of disease. A temporal difference shows that the landscape is no longer suitable for transmission. These results indicate the possibility of identifying future hotspots which could aid the management of the disease.

Abstract
Remote sensing, geographical information systems (GIS) and spatial analysis provide important tools that are as yet under-exploited in the fight against disease. As the use of such tools becomes more accepted and prevalent in epidemiological studies, so our understanding of the mechanisms of disease systems has the potential to increase. This paper introduces a range of techniques used in remote sensing, GIS and spatial analysis that are relevant to epidemiology. Possible future directions for the application of remote sensing, GIS and spatial analysis are also suggested.

Abstract
Alveolar echinococcosis is a rare but fatal disease in humans and is caused by the fox tapeworm Echinococcus multilocularis. The densities of fox and grassland rodent populations and the interactions between them influence E. multilocularis transmission rates in Europe. Successful rabies control has caused fox populations and E. multilocularis prevalence rates to increase in many European countries. The potential increase of the infection pressure on the human population motivates the monitoring of the infection status of foxes over space and time. Detection of E. multilocularis antigen levels in fox faecal samples collected in the field might provide a pragmatic methodology for epidemiological surveillance of the infection status in wildlife hosts across large areas, as well as providing an indication of the spatial distribution of infected faeces contaminating the environment. In this paper, a spatial analysis of antigen levels detected in faeces collected in the Franche-Comté region of eastern France is presented. In Franche-Comté, rodent outbreaks have been observed to originate in areas rich in grassland. Spatial trends in fox infection levels were modelled here as a function of the composition ratio of grassland in the landscape derived from the CORINE land-cover map. Kriging models incorporating the grassland trend term were compared to a variety of models in which five alternative trend expressions were used: the alternative trend expressions included linear and quadratic polynomials on the x and y coordinates with and without a grassland term, and a constant mean model. Leave-one-out cross-validation indicated that the estimation errors of kriging with a trend models were significantly lower when the trend expression contained the grassland index term only. The relationship between observed and predicted antigen levels was strongest when the estimated range of autocorrelation was within the home range size of a single fox. The over-dispersion of E. multilocularis in foxes may therefore account for the majority of spatial autocorrelation locally, while regional trends can be successfully modelled as a function of habitat availability for intermediate hosts.

Abstract
Increases in neuronal nicotinic receptors (nAChRs) in response to nicotine exposure have been reported in cell cultures, rodent brains, and in the brains of human smokers. The present study examines alterations in alpha4 and alpha7 nAChR subunit cellular expression in human hippocampus and entorhinal cortex from normal elderly individuals with known smoking history. There were significant increases in the intensity of alpha4 immunoreactive neuropil, but not the number of cell bodies, in many regions of hippocampus and entorhinal cortex in smokers compared to age-matched non-smokers and ex-smokers. There was also an increase in alpha7 immunoreactive perikarya in the granular cell layer of dentate gyrus in smokers but not other regions examined. There was, in contrast, a significant reduction in alpha7 immunoreactive astrocytes in smokers and ex-smokers compared to non-smokers. These findings suggest exposure to tobacco smoke acutely up-regulates alpha4 receptors in axon terminals and dendrites but not perikarya, whereas tobacco smoking induced down-regulation of alpha7 expression on astrocytes is a long-term effect. As the alpha4 subunit decreases with ageing and degenerative diseases such as Alzheimer's disease, whereas alpha7 increases in astrocytes in Alzheimer's disease, the findings further indicate the therapeutic relevance of nicotinic agonists such as nicotine.

Abstract
Neuronal nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels composed of alpha and beta subunits with specific structural, functional and pharmacological properties. In this study the distribution of alpha3, alpha4, alpha7, beta2 and beta4 nAChR subunits in the human hippocampus was investigated using immunohistochemistry. Most pyramidal neurons, pre-alpha cells of the entorhinal cortex and dentate granule cells were immunoreactive for all subunits. Small islands of alpha7 immunoreactive cells were present in the outer presubiculum. alpha4 and beta2, and alpha3, alpha4 and beta2 immunoreactive fibre tracts were present in the stratum radiatum and subiculum, respectively, suggesting nAChRs may play a role in modulating inputs to the hippocampus via Schaffer collaterals and along the perforant pathway. Some astrocytes were immunoreactive for alpha3, alpha7 and beta4 subunits. Immunoreactivity to all subunits was noted in association with blood vessels. These results indicate the involvement of multiple nAChR subtypes in the modulation of both neuronal and non-neuronal functions in the human hippocampus.

Abstract
Risk factors for the transmission of Echinococcus multilocularis to humans operate at a range of spatial scales. Over a large area, such as China, regional scale risk is correlated with variation in climatic conditions because of its effect on the spatial distribution of landscapes that can support E. multilocularis transmission in wildlife hosts and the probability of egg survival. At a local scale of a few kilometres, or tens of kilometres, transmission risk is related to the spatial proximity of human populations and landscapes with active transmission. At the patch scale, when considering individual villages or households, human behavioural factors are important and for individuals genetic and immunological factors play a role. Satellite remote sensing can provide landscape information at a range of spatial scales and provide a spatial framework within which to examine transmission patterns. This paper reviews the application of remotely sensed data and spatial data analysis to develop a better understanding of disease transmission and shows how such data have been used to examine human alveolar echinococcosis infection patterns, at a range of spatial scales, in an endemic area in central China.

Abstract
Mapping of nicotinic acetylcholine receptor (nAChR) subtypes and subunits in human brain is far from complete, however it is clear that multiple subunits are present (including alpha3, alpha4, alpha5, alpha6 and alpha7, beta2, alpha3 and beta4) and that these receptors are not solely distributed on neurones, but also on cerebral vasculature and astrocytes. It is important to elucidate subunit composition of receptors associated with different cell types and pathways within the human CNS in terms of potential nicotinic therapy for a range of both developmental and age-related disorders in which nAChR attenuation occurs. Reductions in nAChRs are reported in Alzheimer's and Parkinson's diseases, dementia with Lewy bodies, schizophrenia and autism, but may not be associated with reduced cortical cholinergic innervation observed in vascular dementia or occur at an early stage in Down's syndrome. Changes in nAChR expression in neuropsychiatric disorders appear to be brain region and subtype specific and have been shown in some instances to be associated with pathology and symptomatology. It is likely that deficits in alpha4-containing receptors predominate in cortical areas in Alzheimer's disease and autism, whereas reduction of alpha7 receptors may be more important in schizophrenia. Changes in astrocytic and vascular nAChR expression in neurodegenerative diseases should also be considered. Studies using both animal models and human autopsy tissue suggest that nAChRs can play a role in neuroprotection against age-related pathology. It is possible that the development of nAChR subtype specific drugs may lead to advances in therapy for both age-related and psychiatric disorders.

The frequencies of small oscillations about the critical droplet are obtained from a Heun equation. We solve the Fokker-Planck equation for the phase-space probability density by projecting onto the eigenfunction basis. We present a comparison with simulations for the case of the asymmetric straight phi(4) potential.

Abstract
HYPOTHESIS Laparoscopic Heller esophageal myotomy improves esophageal clearance and symptoms of achalasia in the early and late postoperative periods. DESIGN We followed up 98 consecutive patients attending a referral center between February 1, 1994, and July 1, 2000, who underwent laparoscopic myotomy. Operative time, complications, and length of stay were recorded. Postoperative outcomes were assessed using Van Trappen symptom scores (1 indicates no symptoms; 2, symptoms occurring less than once a week; 3, symptoms occurring more than once weekly; and 4, persistent symptoms) and scintigraphic esophageal transit studies. RESULTS Of 98 patients, 91 underwent anterior fundoplication. There were no open conversions and 1 mucosal perforation, which was closed laparoscopically without complications. Mean operative times and postoperative days were 3.2 hours and 4.3 days, respectively, in the first 32 patients and 1.7 hours and 2.3 days, respectively, in the last 32 patients (P<.001). Postoperative complications included pneumothorax (4% of patients), atelectasis (5%), and delayed gastric emptying (1%). Seventy-five percent of patients gained weight after surgery. At longest follow-up, 91% of patients were satisfied with the outcome of the procedure. Mean Van Trappen scores for dysphagia improved from 4.0 in the preoperative period to 1.2 at early and late follow-up (P<.001). Fluid retention at 10 minutes in the upright position was 47% in the preoperative period and improved at early and late follow-up to 21% and 20%, respectively (P<.001). CONCLUSIONS Laparoscopic Heller myotomy can safely reverse the symptoms of achalasia and improve esophageal transit. These benefits, realized during the early postoperative period, were maintained at longest follow-up.

Abstract
OBJECTIVE To determine the effects of therapy with inhaled nitric oxide (NO) gas and partial or complete blockade of endogenous NO synthesis with N(omega)nitro-L-arginine (L-NA) on the hemodynamic responses to group B streptococci infusion in newborn piglets. DESIGN Randomized, acute intervention study. SETTING Animal research laboratory. SUBJECTS Twenty-five anesthetized piglets younger than 3 days of age divided into five groups. INTERVENTIONS Heat-killed group B streptococci (GBS) were infused systemically until a 50% increase in pulmonary artery pressure (PAP) was obtained, and the infusion was continued for another 2 hrs. The five groups were designed as follows: group 1, sepsis control: continuous GBS infusion, with two brief trials (10 mins) of inhaled NO given after the initial development of pulmonary hypertension and again 2 hrs later; group 2, continuous inhaled NO: NO was given at 40 ppm for 2 hrs during GBS infusion; group 3, high-dose L-NA pretreatment: 10 mg/kg L-NA bolus followed by 1 mg/kg/min before, and continuing throughout, GBS infusion; group 4, high-dose L-NA: same dose as in group 3, but given after the start of the GBS infusion with continuous inhaled NO at 40 ppm; and group 5, low-dose L-NA: 3 mg/kg bolus given after start of GBS infusion with continuous inhaled NO at 40 ppm. MEASUREMENTS AND MAIN RESULTS The sepsis controls, group 1, had an increase in PAP, which took 15-45 mins to develop, from a mean of 3.4 (SD 0.7) to 5.9 (1.9) kPa (p < .05), at which time the cardiac index had decreased from 169 (28) to 146 (46) mL/kg/min (p < .05). Brief inhaled NO during the early phase decreased PAP to normal. Two hours later, PAP had increased to 6.1 (0.2) kPa and cardiac index had decreased to 88 (31) mL/kg/min. Inhaled NO after 2 hrs decreased PAP to 3.2 (0.5) kPa and increased cardiac index to 106 (44) ml/kg/min (p < .05). Continuous inhaled NO (group 2) ameliorated the deterioration in cardiac index, which at 2 hrs was 140 (30) mL/kg/min (significantly greater than in the sepsis controls) (p < .05). The L-NA-pretreated animals (group 3) had a greater increase in PAP and pulmonary vascular resistance index when GBS infusion was started. PAP increased from 3.0 (0.7) to 7.3 (1.5) kPa within 15 mins, and cardiac index simultaneously decreased to 68 (20) mL/kg/min. Cardiac index subsequently rapidly deteriorated to 48 (21) mL/kg/min, and only one of five animals survived for 2 hrs. Group 4 animals also developed a rapid deterioration in cardiac output, and only two of five survived for 2 hrs. Group 5 animals had results indistinguishable from group 2 animals. CONCLUSION Pulmonary hypertension and shock resulting from GBS infusion in newborn piglets are much worse if endogenous NO production is completely inhibited. Continuous inhaled NO with or without low-dose L-NA inhibits the decrease in cardiac output.

Abstract
BACKGROUND The ideal treatment for achalasia permanently eliminates the dysfunctional lower esophageal sphincter, relieving dysphagia and regurgitation; prevents gastroesophageal reflux; and has an acceptable morbidity rate. Controversy exists concerning whether the thoracoscopic Heller Myotomy (THM) or laparoscopic Heller myotomy (LHM) technique is the best approach to a modified Heller myotomy for achalasia. STUDY DESIGN We performed a retrospective comparison of the patient characteristics, operative results, postoperative symptoms, and the learning curves for the procedures of 24 patients undergoing THM and 63 patients undergoing LHM between 1991 and 1998. RESULTS Preoperative patient variables in each group revealed similar distributions for age, gender, and prevalence of previous pneumatic dilation. Mean operating room (OR) times were 4.3 hours (range 2.9 to 5.6 hours) for THM and 3.0 hours (range 1.5 to 6.5 hours) for LHM (p = 0.01). Three esophageal perforations occurred in the THM group and two in the LHM group. Conversion to an open procedure took place in five THM operations (21%) and one LHM operation (2%) (p = 0.005). There were no postoperative esophageal leaks. Mean postoperative length of stay (LOS) for THM was 6.1 days (range 1 to 17 days) and for LHM was 4.0 days (range 1 to 12 days) (p = 0.03). Learning-curve analysis of the first 24 LHM patients compared with the most recent 24 revealed greater OR time in the first 24 mean 3.6 hours, (range 2.0 to 6.5 hours) versus mean 2.3 hours, (range 1.5 to 3.7 hours; p = 0.01), and greater LOS mean 5.5 days, (range 3 to 12 days) versus mean 3.1 days, (range 1 to 8 days; p < 0.01). One esophageal perforation occurred in each subgroup. A similar analysis in the first 12 THM patients compared with the most recent 12 revealed no significant improvement in OR times or LOS. Three esophageal perforations occurred in the latter subgroup only. All patients had preoperative daily dysphagia to solids. Followup data for LHM (n = 49) (median 17 months, range 1 to 39 months) and THM (n = 15) (median 42 months, range 1 to 69 months) revealed no or minimal dysphagia in 90% (44 of 49) after LHM and 31% (4 of 13) after THM (p < 0.01). No or minimal heartburn was present in 89% (41 of 46) after LHM and 67% (8 of 12) after THM (p < 0.05). Regurgitation was absent or minimal in 94% (46 of 49) after LHM and 86% (12 of 14) after THM (p = 0.3). CONCLUSIONS LHM was associated with decreased OR time, decreased rate of conversion to an open procedure, and shorter LOS compared with THM. LHM was superior to THM in relieving dysphagia and preventing heartburn. LHM may be the preferred surgical treatment of achalasia in some patients.

Abstract
BACKGROUND The incidence of adenocarcinoma of the cardia is increasing. The surgical management remains controversial. The present study reviews our experience with surgically resected adenocarcinoma of the cardia. METHODS A retrospective review of 153 cases of surgically resected adenocarcinoma of the cardia was performed. Preoperative radiotherapy was used in 31 patients. The surgical approach, morbidity, mortality, impact of preoperative radiotherapy, and survival were determined. RESULTS The type of resection performed was a transhiatal esophagogastrectomy in 78%, a transthoracic esophagogastrectomy in 21%, and a transabdominal esophagogastrectomy in 1%. The in-hospital mortality rate was 4%. The frequency of complications was not associated with the use of preoperative radiotherapy or surgical approach. The 1-year (61%), 2-year (38%), 3-year (23%), and 5-year (16%) survival were not affected by the use of preoperative radiotherapy or surgical approach. Survival was significantly associated with stage and the presence of lymph node metastasis. CONCLUSIONS Adenocarcinoma of the cardia is associated with a poor long-term prognosis. The long-term survival does not appear to be affected by the use of preoperative radiotherapy or by surgical approach.

Abstract
The soil and plants at a 27.4 ha field site near Kalgoorlie, Western Australia, were surveyed and analysed with multivariate statistics. Cluster analysis identified four distinct plant communities at the study site. These were: Acacia acuminata shrubland Eucalyptus gvfithsii woodland Eucalyptus salrnonophloia woodland 'Ground Covers' - areas characterised by the presence of generalist herbs, low shrubs and weeds, and the absence of dominant upper storey species. Discriminant function analysis identified site elevation and soil exchangeable Ca as the primary environmental discriminants between the plant communities. Using these two variables, sample points were classified into one of the four plant communities. The two methods of classification matched well, with classification based on the two environmental variables providing an indication of which plant community would be most likely to establish in disturbed areas. This type of information can be important to revegetation programs in the region, guiding the use of appropriate plant species under different rehabilitation conditions. Key wcrds: environmental variables, plant communities, multivariate analysis, classification, revegetation

Abstract
BACKGROUND The purpose of this study was to determine the initial results of laparoscopic esophageal myotomy and anterior fundoplication in the treatment of 26 patients with achalasia. METHODS Operative time, complications, and length of hospitalization were recorded for each patient. Postoperative outcomes were assessed by a standardized patient questionnaire, 24-hour esophageal pH studies, and esophageal transit studies. RESULTS Twenty-six consecutive patients with class IV dysphagia underwent a laparoscopic esophageal myotomy and anterior partial fundoplication, with a single incidence of intraoperative esophageal perforation. The mean operative time was 3.5 hours. The median length of hospitalization was 5 days. Of the 21 patients for whom follow-up was available (median follow-up, 4 months), 19 (90%) were satisfied and 2 (10%) were somewhat satisfied with their surgery. After operation, 14 of the 21 patients (67%) reported no dysphagia (class I), whereas 6 (28%) had class II dysphagia (less than once per week) and only 1 (5%) had class III dysphagia (greater than once per week). Liquid-phase esophageal transit studies (n = 14) revealed a significant improvement in esophageal clearance in the supine position from 18% before operation to 44% after operation (p = 0.006). Distal esophageal acid exposure was normal in 6 of 7 patients. CONCLUSIONS These early results suggest that laparoscopic esophageal myotomy and anterior partial fundoplication provides efficacious treatment of achalasia.

Abstract
OBJECTIVES To investigate the cause of sporadic motor neuron disease (MND) by twin study, so allowing (1) estimation of the genetic contribution, and (2) collection of matched pairs for a case-control study of possible environmental factors. METHODS 10872 death certificates bearing the diagnosis MND were collected from 1979 to 1989 inclusive. Inspection of individual birth entries allowed identification of potential twins. The status of each co-twin was determined and contact made through the National Health Service Central Register (NHS-CR) and their general practitioner (GP). The diagnosis of MND was verified via the co-twin and relatives, and medical records where available. Zygosity was assessed using a recognised questionnaire. Details concerning environmental exposures and health were gathered by interview of cotwin and relatives using a semistructured questionnaire. Heritability (h2) of MND was estimated, and the environmental information was analysed by conditional logistic regression modelling. RESULTS Seventy seven probands were identified, of whom 26 were monozygotic and 51 dizygotic. Four monozygotic probands were concordant, but two probands came from a family known to have familial MND. The estimated heritability was between 0.38 and 0.85. Most environmental risk factors were not significant. Regular vehicle maintenance (odds ratio (OR) = 7.0; 95% confidence interval (95% CI) 1.3-89.9) and occupational paint usage (OR = 3.75; 95% CI 1.0-17.1), however, occurred significantly more often in the affected cases. CONCLUSIONS This "death discordant" method for twin collection has proved to be viable, and has allowed the ascertainment of a large population sample in a rare disease. The genetic role in sporadic MND is substantial, and higher than expected. Exposure to industrial chemicals, particularly constituents of petrochemicals and paints, may contribute to the aetiology of MND.

Abstract
BACKGROUND AND METHODS A comparison of total vs. partial laparoscopic fundoplication was conducted in 89 patients from July 92 to June 96. Parameters examined were operating room (OR) times, conversion rates, and perioperative complications. Patient satisfaction, control of symptoms, and late complications were assessed by follow-up at a mean of 6 and 15.4 months. RESULTS There were six conversions to open surgery resulting in 48 laparoscopic total (LTF) and 35 laparoscopic partial (25 anterior and 10 Toupet) fundoplications (LPF). The following results were obtained for each respectively: preop Demeester score 44 vs. 39; OR time 2.9 vs. 2.5 hours; length of stay 3.6 vs. 4.1 days; early morbidity 25% vs. 1%. There were no mortalities. At a mean follow-up of 6 months, new-onset dysphagia was present in 8 (17%) vs. 2 (8%), respectively (NS), and both total and partial fundoplications appeared successful in controlling symptoms (98% vs. 97%). At a mean follow-up of 15.4 months, heartburn was resolved or improved in 76% vs. 87% (NS); regurgitation was improved or resolved in 93% vs. 93%; and patient satisfaction with the procedure was present in 93% vs. 97% (NS). Persistent dysphagia was present in 7.3% vs. 10.3% (NS) of patients. Early satiety was present more often in the partial fundoplication group (56% vs. 83% P = .03). CONCLUSIONS Early follow-up suggests equal efficacy in controlling symptoms and in achieving patient satisfaction. A 6-month follow-up suggested a higher incidence of new dysphagia in the total fundoplication group; however, at 15-month follow-up there was no significant difference.

Abstract
BACKGROUND To evaluate the success of a novel approach to twin studies using death discordant twin pairs in a disease of low prevalence. METHOD A population study based on all registered deaths at the Office of Population Censuses and Surveys of England and Wales, classified under the ICD code 335.2 (motor neuron disease [MND]) for the period 1979-1989 inclusive. From the above database of 10,872 people, individuals born after 31 December 1899 were traced in the Birth Indices for England & Wales to enable identification of possible twins. In all 131 twin pairs were found and the co-twin details were sent to the National Health Service Central Register (NHS-CR) to enable location of the relevant Family Health Services Authority and thence the co-twin's general practitioner (GP). A letter requesting access was sent to the family practitioners. If given, the co-twin can be approached and interviewed. RESULTS The search produced: 54 living co-twins; 31 who died as adults; 29 infant deaths; 5 emigrated; 3 incorrectly diagnosed index twins; and 9 untraceable co-twins. Among the adult deaths two concordant pairs were identified. This has created the largest twin population sample worldwide for MND. CONCLUSION This new twin study method is clearly viable, and has produced a large unbiased sample compared to that possible using traditional methods. It relies heavily on the accuracy of death certificates and zygosity reporting by living co-twins, but is possibly the only way of collecting twins in rare conditions.

Abstract
We hypothesized that nitric oxide (NO) inhalation in a model of meconium aspiration in newborn piglets would decrease pulmonary vascular resistance. Seven neonatal piglets were obtained at less than 48 hr of age and instrumented under fentanyl anesthesia. Inhaled NO (40 parts per million) was administered during normoxia and again after hypoxia was induced by reducing FiO2 to 0.13. During normoxia NO inhalation caused a fall in pulmonary artery pressure from a mean of 3.15 (SD 0.8) kPa to 2.84 (SD 0.7) kPa (P < 0.01). Hypoxia (mean arterial O2 saturation 35%) increased PA pressures to a mean of 5.4 (SD 1.6) kPa and NO administration during hypoxia decreased PA pressures to 3.6 (SD 1.2) kPa (P < 0.001). In order to determine the effects of NO in a model of meconium aspiration, 6 to 7 mL/kg of 20% human meconium in normal saline was instilled into the trachea. This procedure induced hypoxemia (mean SaO2 43.4%, SD 19), respiratory acidosis, (mean PaCO2 12.1 kPa, SD 0.5; mean pH 7.04, SD 0.03), and pulmonary arterial hypertension (mean pulmonary artery pressure 6.0 kPa, SD 1.3) despite ventilation with 90% oxygen. Inhaled NO was then administered in concentrations of 5, 10, 20, 30, 40, 60, and 80 parts per million in random order according to a Latin square design.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Adult intraabdominal surgery performed with the minimal-access technique has created a revolution in surgery. This technique has remained largely unused for pediatric surgical procedures because of concerns regarding its safety and efficacy. Presently, intraabdominal insufflation of CO2 is the preliminary step to performing minimal access surgery. In this study, an animal model was developed to determine the effects of intraabdominal CO2 insufflation in the infant. Eight piglets (4 to 6 kg; 14 to 19 days of age) were instrumented under fentanyl anesthesia to allow measurement of arterial blood pressure (BP), central venous pressure (CVP), heart rate (HR), cardiac index (CI), inferior vena cava pressure (IVCp), inferior vena cava flow (IVCf), mediastinal pressure (Mp), partial pressure of CO2 (PaCO2), and minute ventilation (VE) at baseline and during 1 hour of CO2 insufflation to a pressure of 15 mm Hg and again when ventilation was increased to control PaCO2 levels. Continuous recording of data allowed time-course analysis of 15-minute blocks to determine the rate of change of measured variables. A second group of 6 piglets (4 to 6 kg) underwent the same instrumentation, but their baseline values were compared with those during N2O insufflation to isolate the effects of increased intraabdominal pressure. During CO2 insufflation alone, PaCO2 increased by 31% (P < .0001). This increase occurred within the first 15 minutes of insufflation and then remained stable. The increase was likely the result of increased CO2 absorption from the peritoneal cavity because VE was unchanged.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Inhaled nitric oxide has been reported to act as a specific pulmonary vasodilator. We used the newborn piglet to create acute hypoxic pulmonary hypertension and examined the effect of inhaled nitric oxide in this model. Six newborn piglets were instrumented in order to measure cardiac index, pulmonary arterial pressure, and systemic arterial pressure. Pulmonary hypertension was induced by reducing the fraction of inspired oxygen to 0.12 to 0.14. With hypoxia (arterial oxygen saturation between 35 and 45%), pulmonary arterial pressure increased by 48% (p < 0.01), pulmonary vascular resistance increased by 74% (p < 0.01), and both systemic arterial pressure and systemic vascular resistance decreased by 38 and 31%, respectively (p < 0.01). The animals were then giving varying concentrations of inhaled nitric oxide between 5 and 80 parts per million in random order. All concentrations of nitric oxide were associated with a rapid decrease in pulmonary arterial pressure and pulmonary vascular resistance (p < 0.001). Cardiac index increased (p < 0.001) and systemic vascular resistance significantly decreased (p = 0.01) with all doses of inhaled nitric oxide. The ratio of pulmonary to systemic vascular resistance decreased with all levels of inhaled nitric oxide (p < 0.001). For all of the above observations there was no significant difference noted between the varying doses of nitric oxide. The time course of the pulmonary arterial pressure response to nitric oxide was approximately twice as fast as that seen with the inhalation of 100% oxygen (10, 50, 90% responses of 4.1, 8.8, 88.6 versus 6.7, 51.9, 197 s, respectively; p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The isolation and structural characterization of 1 : 1 adducts of copper(1) chloride (1) and bromide (2) with pyridine-4-carbonitrile (L) is described; crystals of the two complexes are isomorphous (monoclinic, P21/c, a ≈ 3.9, b ≈ 14.7, c ≈ 13.0 � , β ≈ 96°, Z 4; R0.047, 0.063 for No 630, 707 'observed' reflections respectively). Unlike the 1 : 1 adducts with the parent pyridine and benzonitrile ligands which are 'stair' polymers, these complexes comprise 'split-stair' strands woven into a two-dimensional sheet by crosslinking ambidentate ligands. Cu-N ( nitrile ) (1.942(9), 1.96(1) � ) are appreciably shorter than Cu-N (pyridine) (2.066(8), 2.04(1) � ), as in the parent base complexes. The two Cu-X are similar in each case: 2.336(6), 2.366(3) � (CI); 2.460(3), 2.486(3) � (Br). The iodide adduct (3) isolated is of novel stoichiometry (Cul : L, 4 : 5) (monoclinic, P21/c; a 10.140(5), b 12.214(6), c 15.157(8) � , β 99.99(4)° Z 2; R 0.048, No 2416). It is a linear polymer, comprising tetranuclear Cu414L4 'step' units, crosslinked across inversion centres by disordered ambidentate ligands.

Abstract
Fractures of the femoral shaft are often treated by an established method of internal fixation, such as a medullary nail or a plate and screws, to obviate the many disadvantages of traction and prolonged rest in bed. Fractures of the femoral shaft which are severely comminuted and open are usually unsuitable for internal fixation. Between July 1981 and March 1983 we treated seven patients with severely comminuted fractures of the femoral shaft (of which three were open), using the ASIF tubular external fixator system or the Wagner apparatus. The technique of application of the external fixator is important and is described. When correctly applied, the knee's movement was not restricted and few complications were experienced. All the fractures united within 8 months in a good position without shortening, and none required an additional operation. The use of the external fixator in these patients reduced their time in the hospital and facilitated their postoperative rehabilitation by allowing uncomplicated healing of a complicated fracture.

Abstract
The tumor-promoting drug 4 beta-phorbol 12-myristate 13-acetate (TPA) causes the loss of myofibrils in primary cultures of chick embryonic myotubes [9]. When myofibrils in chick myotubes are dispersed by TPA treatment (5 X 10(-8) M), there remains a class of non-myofibrillar actin filaments that are sensitive to subsequent breakdown by cytochalasin D. Microfilament bundles in fibroblasts in the same cultures seem unaffected by this TPA treatment, but are also broken down by cytochalasin D (0.2 micrograms/ml); this dose has little effect on myofibrils. We have previously shown that treatment of chick myotubes with cytochalasins would destabilize clusters of acetylcholine receptors (AChRs) [6]. In order to further examine the relationship between actin filaments and cell surface AChRs, we have used the receptor-specific ligand alpha bungarotoxin (a-BGT) to study the fate of AChR clusters in drug-treated and control myotubes. Cells treated with TPA showed no loss in the number of receptor clusters present on their surface. However, if these cells were also treated with cytochalasin D, cluster number was reduced to approximately the same value as seen for cytochalasin treatment alone (50% of the control value). These results suggest that the cytoskeletal link to these cell surface receptors is not mediated by attachment to the alpha actin-containing myofibrils, but rather clustered AChRs are stabilized by a class of non-myofibrillar actin filaments.
