Abstract
Globally, soils store two to three times as much carbon as currently resides in the atmosphere, and it is critical to understand how soil greenhouse gas (GHG) emissions and uptake will respond to ongoing climate change. In particular, the soil-to-atmosphere CO2 flux, commonly though imprecisely termed soil respiration (RS ), is one of the largest carbon fluxes in the Earth system. An increasing number of high-frequency RS measurements (typically, from an automated system with hourly sampling) have been made over the last two decades; an increasing number of methane measurements are being made with such systems as well. Such high frequency data are an invaluable resource for understanding GHG fluxes, but lack a central database or repository. Here we describe the lightweight, open-source COSORE (COntinuous SOil REspiration) database and software, that focuses on automated, continuous and long-term GHG flux datasets, and is intended to serve as a community resource for earth sciences, climate change syntheses and model evaluation. Contributed datasets are mapped to a single, consistent standard, with metadata on contributors, geographic location, measurement conditions and ancillary data. The design emphasizes the importance of reproducibility, scientific transparency and open access to data. While being oriented towards continuously measured RS , the database design accommodates other soil-atmosphere measurements (e.g. ecosystem respiration, chamber-measured net ecosystem exchange, methane fluxes) as well as experimental treatments (heterotrophic only, etc.). We give brief examples of the types of analyses possible using this new community resource and describe its accompanying R software package.

Abstract
Canopies of adult European beech (Fagus sylvatica) and Norway spruce (Picea abies) were labeled with CO(2) depleted in (13)C to evaluate carbon allocation belowground. One-half the trees were exposed to elevated O(3) for 6 yrs prior to and during the experiment. Soil-gas sampling wells were placed at 8 and 15 cm and soil CO(2) was sampled during labeling in mid-late August, 2006. In beech, delta(13)CO(2) at both depths decreased approximately 50 h after labeling, reflecting rapid translocation of fixed C to roots and release through respiration. In spruce, label was detected in fine-root tissue, but there was no evidence of label in delta(13)CO(2). The results show that C fixed in the canopy rapidly reaches respiratory pools in beech roots, and suggest that spruce may allocate very little of recently-fixed carbon into root respiration during late summer. A change in carbon allocation belowground due to long-term O(3) exposure was not observed.

Abstract
Pacific herring were susceptible to waterborne challenge with viral haemorrhagic septicaemia virus (VHSV) throughout their early life history stages, with significantly greater cumulative mortalities occurring among VHSV-exposed groups of 9-, 44-, 54- and 76-day-old larvae than among respective control groups. Similarly, among 89-day-1-year-old and 1+year old post-metamorphosed juveniles, cumulative mortality was significantly greater in VHSV-challenged groups than in respective control groups. Larval exposure to VHSV conferred partial protection to the survivors after their metamorphosis to juveniles as shown by significantly less cumulative mortalities among juvenile groups that survived a VHS epidemic as larvae than among groups that were previously naïve to VHSV. Magnitude of the protection, measured as relative per cent survival, was a direct function of larval age at first exposure and was probably a reflection of gradual developmental onset of immunocompetence. These results indicate the potential for easily overlooked VHS epizootics among wild larvae in regions where the virus is endemic and emphasize the importance of early life history stages of marine fish in influencing the ecological disease processes.

Abstract
The plantar plate is the fibrocartilaginous structure that supports the ball of the foot, withstanding considerable compressive and tensile forces. This study describes the morphology of the plantar plate in order to understand its function and the pathologic disorders associated with it. Eight lesser metatarsophalangeal joint plantar plates from three soft-embalmed cadavers (74-92 years, two males, one female), and eight lesser metatarsophalangeal joint plantar plates from a fresh cadaver (19-year-old male) were obtained for histology assessment. Paraffin sections (10 microm) in the longitudinal and transverse planes were analyzed with bright-field and polarized light microscopy. The central plantar plate collagen bundles run in the longitudinal plane with varying degrees of undulation. The plantar plate borders run transversely and merge with collateral ligaments and the deep transverse intermetatarsal ligament. Bright-field microscopic evaluation shows the plantar aspect of the plantar plate becomes ligament-like the further distally it tapers, containing fewer chondrocytes, and a greater abundance of fibroblasts. The enthesis reveals longitudinal and interwoven collagen bundles entering the proximal phalanx with multiple interdigitations. Longer interdigitations centrally compared to the dorsal and plantar aspects suggest that the central fibers experience the greatest loads.

Abstract
Swimming stamina, measured as time-to-fatigue, was reduced by approximately two-thirds in rainbow trout experimentally infected with Ichthyophonus. Intensity of Ichthyophonus infection was most severe in cardiac muscle but multiple organs were infected to a lesser extent. The mean heart weight of infected fish was 40% greater than that of uninfected fish, the result of parasite biomass, infiltration of immune cells and fibrotic (granuloma) tissue surrounding the parasite. Diminished swimming stamina is hypothesized to be due to cardiac failure resulting from the combination of parasite-damaged heart muscle and low myocardial oxygen supply during sustained aerobic exercise. Loss of stamina in Ichthyophonus-infected salmonids could explain the poor performance previously reported for wild Chinook and sockeye salmon stocks during their spawning migration.

Abstract
OBJECTIVE To investigate the long-term differential drug effects on cognitive functioning in school-aged children exposed to antiepileptic drugs (AEDs) in utero. METHODS Mothers with epilepsy were recruited from specialist epilepsy clinics and obstetric clinics from the Liverpool and Manchester region. The mothers and their children were recruited without prior knowledge of their AED treatment during pregnancy or the health of the offspring. A battery of neuropsychological tests was applied to each mother-child pair in order to obtain a neuropsychological profile for each child. RESULTS Neuropsychological investigation was performed on 249 children between the ages of 6 and 16. Children exposed to sodium valproate had a significantly lower verbal IQ when compared to children exposed to other antiepileptic drugs or not exposed at all. The same children were more likely to have an IQ below 69 and more likely to have memory impairment when compared to the other groups. The mothers' IQ, exposure to sodium valproate, and the number of tonic-clonic seizures during pregnancy were significant predictors of verbal IQ in this population. CONCLUSIONS This retrospective study highlights the potential harmful effects of sodium valproate exposure in utero on neuropsychological development.

Abstract
OBJECTIVES To determine the prevalence of cognitive delay and possible associated dysmorphic features in children exposed to antiepileptic drugs (AEDs) in utero. DESIGN Retrospective study of children born to mothers with epilepsy. SETTING Regional epilepsy clinics in Liverpool and Manchester, UK. PARTICIPANTS Children aged between 6 months and 16 years born to mothers with epilepsy. MAIN OUTCOME MEASURES Structured interviews, hospital records, clinical examination, and psychometric tests (Wechsler) were used to assess exposure and intelligence quotient (IQ). Blinded assessment of photographs was used to score children with characteristic dysmorphic features. RESULTS A total of 249 children aged 6 and over were studied: 41 were exposed to sodium valproate, 52 to carbamazepine, 21 to phenytoin, 49 to polytherapy, and 80 were unexposed. Mean verbal IQ was significantly lower in the valproate group compared to unexposed and other monotherapy groups. Multiple regression analysis showed that both valproate exposure and frequent tonic-clonic seizures in pregnancy were significantly associated with a lower verbal IQ despite adjusting for other confounding factors. There was a significant negative correlation between dysmorphic features and verbal IQ in children exposed to valproate. CONCLUSIONS This study identifies valproate as a drug carrying potential risks for developmental delay and cognitive impairment and is the first to suggest that frequent tonic-clonic seizures have a similar effect. Our results need to be interpreted with caution given their retrospective nature. Women with epilepsy need careful counselling about individual risk benefit of AED treatment before pregnancy.

Abstract
The magnitude of hydraulic redistribution of soil water by roots and its impact on soil water balance were estimated by monitoring time courses of soil water status at multiple depths and root sap flow under drought conditions in a dry ponderosa pine (Pinus ponderosa Dougl. ex Laws) ecosystem and in a moist Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) ecosystem. The fate of deuterated water applied to small plots to create a strong horizontal soil water potential gradient was also monitored to assess the potential for horizontal redistribution of water and utilization of redistributed water by co-occurring shallow-rooted plants. In a 20-year-old Douglas-fir stand, approximately 28% of the water removed daily from the upper 2 m of soil was replaced by nocturnal hydraulic redistribution during late August. In an old-growth ponderosa pine stand, approximately 35% of the total daily water utilization from the upper 2 m of soil appeared to be replaced by hydraulic redistribution during July and August. By late September, hydraulic redistribution in the ponderosa pine stand was no longer apparent, even though total water use from the upper 2 m of soil was nearly identical to that observed earlier. Based on these results, hydraulic redistribution would allow 21 and 16 additional days of stored water to remain in the upper soil horizons in the ponderosa pine and Douglas-fir stands, respectively, after a 60-day drought. At both sites, localized applications of deuterated water induced strong reversal of root sap flow and caused soil water content to cease declining or even temporarily increase at locations too distant from the site of water application to have been influenced by movement of water through the soil without facilitation by roots. Xylem water deuterium values of ponderosa pine seedlings suggested utilization of redistributed water. Therefore, hydraulic redistribution may enhance seedling survival and maintain overstory transpiration during summer drought. These first approximations of the extent of hydraulic redistribution in these ecosystems suggest that it is likely to be an important process in both wet and dry forests of the Pacific Northwest.

Abstract
This study examines the effects of a large-scale cervical cancer prevention campaign in Recife, Brazil between 1994 and 1995. It suggests that while this program effectively motivated women to get pap smears, it reinforced local understandings of the pap smear that ultimately had unintended negative consequences for women's health. It argues that because the campaign connected female sexual activity directly with cervical cancer, the program's message was interpreted by many women to mean that cervical cancer was a sexually transmitted disease and that it would behave like one. Women who were no longer sexually active believed that they did not need to be screened. In addition, women who were sexually active believed that they could use pap smears to diagnose and cure sexually transmitted diseases.

Abstract
Consistent handedness and language laterality are two of the most striking behavioral and cognitive asymmetries observed in humans. Alterations in the typical pattern of cerebral laterality, termed "anomalous dominance," is observed in left-handers and some patients with verbal learning disabilities. We undertook the study of a genetically distinct group of subjects, XXY males (Klinefelter's syndrome; KS), who demonstrate anomalous dominance in a variety of testing paradigms in order to begin to elucidate the molecular basis of anomalous dominance in this population. KS subjects manifest specific verbal learning disability, evidence of altered functional laterality for phonologic processing, and an increase in left-handedness when measured by skill. It is proposed that an alteration in gene dosage in the pseudoautosomal region (PAR) of the sex chromosomes is the most likely explanation for anomalous dominance in these patients. This is especially intriguing in light of previously described genetic models of cerebral laterality that suggest a contributing locus in the PAR, or adjacent high homology regions of the X chromosome. We have developed an ordered DNA microarray covering the X chromosome PAR at high resolution for hybridization with two-color fluorescently labeled probes. We demonstrate the ability to detect changes in hybridization signal that will facilitate efficient large-scale screening of this region for alterations in gene dosage associated with features of anomalous dominance and other cognitive or behavioral phenotypes.

Abstract
To simulate the effects of partial weight bearing on meniscal repair, full-thickness tears were produced in the posteromedial aspect of seven ACL-intact cadaveric knees. Following suture repair, metal markers were imbedded to index the position of the tear. A radiolucent chamber was used to position and load each knee for computed tomography scanning at flexion angles of 0 degrees, 30 degrees, and 60 degrees with and without a load force of 100 lb. Sutures were removed and the tests repeated. Changes in marker distances were obtained for each test condition. Loading produced average dimensional changes of < or =0.5 +/-0.6 mm in either sutured or unsutured menisci. Based on the Friedman test, neither flexion angle, loading, nor suture exerted a significant impact (P> or =.52). These data support clinical accelerated rehabilitation programs previously published. Therefore, partial weight bearing during convalescence is tenable.

Abstract
The identification of differential gene expressionbetween cells is a frequent goal in modern biological research. Here we demonstrate the coupling of representational difference analysis (RDA) of cDNA with microarray analysis of the output for high throughput screening. Two primary Ewing's sarcoma tissue samples with different biological behavior in vivo were compared by RDA: one which was metastatic and progressed rapidly; the other localized and successfully treated. A modified RDA protocol that minimizes the necessary starting material was employed. After a reduced number of subtractive rounds, the output of RDA was shotgun cloned into a plasmid vector. Inserts from individual colonies from the subtracted library were amplified with vector-specific primers and arrayed at high density on glass slides. The arrays were then hybridized with differentially fluorescently labeled starting amplicons from the two tissues and fluorescent signals were measured at each DNA spot. We show that the relative amounts of fluorescent signal correlate well with the abundance of fragments in the RDA amplicon and in the starting mRNA. In our system, we analyzed 192 products and 173 (90%) were appropriately detected as being >2-fold differentially expressed. Fifty unique, differentially expressed clones were identified. Therefore, the use of RDA essentially provides an enriched library of differentially expressed genes, while analysis of this library with microarrays allows rapid and reproducible screening of thousands of DNA molecules simultaneously. The coupling of these two techniques in this system resulted in a large pool of differentially expressed genes.

Abstract
The aim of this study was to investigate the hypothesis that infants at high risk of cerebral palsy would benefit from early physiotherapy. In total, 105 infants with abnormal cranial ultrasound scans were randomized at around term to early physiotherapy or standard treatment (delaying physiotherapy until abnormal physical signs became apparent). At 12 and 30 months there were clinical and objective assessments. Nine infants died and nine were lost to follow-up by 12 months when 87 infants were assessed. One other child had died and three others were lost to follow-up by 30 months when 83 children were assessed. Cerebral palsy was only accurately predicted in 45 (54%) infants. There was no difference in outcome. The difficulty of predicting cerebral palsy reliably and the heterogeneity of the condition should be borne in mind when planning treatment and assessing its efficacy.

Abstract
This paper examines cultural models for breast and cervical cancer among low-income African-American women over 40, in order to better understand how those models might affect cancer screening behavior. The study is part of The Community-Based Cancer Screening Project, which is sponsored by Emory University, Grady Memorial Hospital, and the American Cancer Society. The Screening Project attempts to increase the use of mammography, clinical and self-examination of the breast, and cervical Pap smear among women aged 40 or older in a predominantly African-American, low-income, low educational level population that is currently underserved by any screening activities. The study of cultural models of cancer within the project was prompted by the recognition that if screening programs targeted at specific, underserved, populations are to succeed, cultural as well as logistical barriers to screening must be overcome. Patients and clinicians must each understand how the other perceives cancer, its prevention, and its treatment. Only with this mutual understanding as a foundation, can physicians and their clients cooperate to improve cancer screening rates. Our research results indicate that the cancer models held by the patient population differ significantly from those held by clinicians. Women attending the clinics endure cancer screening tests that to them seem to serve only as heralds of a disease that will ultimately kill them. Most women doubt there is a cure for cancer, though some believe a person may live if the disease is caught in time.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To investigate the effect of normal fetal swallowing and amniotic fluid ingestion on small intestinal disaccharidase development, 13 pregnant New Zealand White rabbits underwent operation on day 24 of a normal 31-day gestation. The right ovarian fetus in the bicornuate uterus underwent esophageal ligation (EL), while the contralateral left fetus underwent cervical exploration only, and served as the control (C). Rabbits were sacrificed on gestational day 31, fetal somatic measurements obtained, and the midjejunum removed for determination of disaccharidase activity and protein content. There was one maternal death, and 9 of 12 fetal pairs survived the entire study period (75%). Results are reported as mean +/- SEM, analyzed by two-tailed Student's t testing with P < .05 being considered significant. Fetal weight was decreased in EL (48.6 +/- 2.7 g) versus C (51.4 +/- 3.2 g) (P = .06). Small intestinal length decreased in EL (49.2 +/- 2.0 cm) versus C (54.9 +/- 1.1 cm) (P = .01). Midjejunal protein content (mg/mL homogenate) was also significantly decreased in EL (38.4 +/- 3.4) versus C (46.2 +/- 3.7) (P = .05). Sucrase activity was not detectable in either group. Lactase activity in jejunal mucosa was not effected when expressed as units of enzyme per milliliter of homogenate (EL = 0.357 +/- 0.03 v C = 0.373 +/- 0.04; P = .70) and units enzyme per gram of protein (EL = 38.8 +/- 4.2 v C = 34.2 +/- 4.6; P = .44). We have confirmed previous studies demonstrating decreases in somatic growth, small intestinal length, and mucosal nutrient transport in rabbit fetuses following esophageal ligation.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The association between completion of primary dipht eria, tetanus and pertussis, measles, mumps, and rubella and polio immunisation courses in Liverpool and five sociodemographic factors, namely the child's sex, position in the family, family type, migration into Liverpool since birth, and local deprivation was examined. Only 68% of children were fully immunised by their second birthday. The immunisation rate for pertussis was 74%, compared with 85-89% for the other antigens. Children who had older siblings, were recorded as living with one parent, had moved into Liverpool or who lived in areas of high deprivation were less likely to complete the full set of antigens and individual courses. Boys were significantly less likely than girls to be fully immunised against pertussis. Differences in the completion of pertussis immunisation associated with the child's sex and with local deprivation were a direct reflection of differences in rates of parental consent. Parental consent did not wholly account for significantly lower rates among children with older siblings, those living with a lone parent, and those who had moved into Liverpool, however. This may reflect the practical difficulties of attending immunisation clinics. To achieve immunisation targets, a more flexible and targeted approach is required of health professionals. This may include the careful targeting of efforts to increase consent and the improvement of access to immunisations by providing domiciliary services or by opportunistic immunisation of infants when they are in contact with primary and community health care services.

Abstract
This study compared three methods of assessing motor impairment during infancy. The 77 infants studied were considered to be at high risk of motor impairment because of abnormal neonatal cranial ultrasound scans or abnormal somatosensory responses. The children were assessed at eight and 12 months post-term by the Movement Assessment of Infants, the Griffiths locomotor development quotient and the limb-by-limb approach, and the results were compared with clinical assessment at 12 months post-term. The sensitivity of the limb-by-limb approach was highest, although its specificity was slightly lower than the other tests. It was also the easiest to perform. While giving information about the quality of movement, none of these methods is a quantitative test of movement.

Abstract
The association between parents in Liverpool consenting to their children being invited for primary immunisations and five sociodemographic factors, namely sex, position of child in the family, family type, migration into Liverpool since birth, and local deprivation was examined. Rates of consent to invitation were over 97% for each antigen except pertussis, which had a consent rate of 83%. Consent to invitation for pertussis vaccine was least likely to have been given for boys, children with older siblings, those recorded as living with a single parent, and those in the most deprived areas. Local deprivation also had an effect on consent to the measles, mumps, and rubella vaccine. Migration into Liverpool had a significant effect on consent to invitation for all antigens except pertussis. The child's sex, family type, and local deprivation had no effect on consent to diphtheria, tetanus, and polio immunisations. Maximising pertussis vaccine uptake will require more attention to be paid to those parents who have been identified as being less likely to give consent. It is particularly important that consistent and clear advice about immunisations is made available to parents with two or more children, lone parents, and those living in materially deprived areas. Our findings challenge some of the assumptions underlying the principles of 'first parent visiting', at least so far as pertussis is concerned.

Abstract
In summary, the emergency department or office-based physician should distinguish first between inflammation and injury. A clinical diagnosis of fracture should be made before obtaining and reading films. Comparison views help to resolve doubt. A neurologic examination should be documented before undertaking reduction. Finally, if in doubt, a splint for 24 to 48 hours until an orthopedic opinion is available causes no harm.

Abstract
The clinical specificity and sensitivity of imaging with 99mTc was evaluated prospectively in 104 consecutive patients admitted to the hospital for diagnostic/surgical arthroscopy. Four distinct patterns of radionuclide activity were seen that correlated with observed arthroscopic findings. These patterns of activity were seen with degenerative joint disease (DJD) or severe rotational instability, meniscal pathology, fracture of the subchondral plate or full thickness cartilaginous ulceration, and synovitis. Radionuclide imaging was seen to be extremely sensitive and highly specific for all four patterns of activity. The observed association of subchondral plate injury with meniscal pathology may present an explanation for the observed poor outcome in a limited number of patients following meniscectomy.

Abstract
Osteoid osteoma, a benign osteoblastic tumour comprised of osteoid and atypical bone, is a well-known entity. However, clinical diagnosis may be delayed, especially when the pain is referred to a nearby joint. This paper reports a series of 11 cases occurring in physically active patients in whom the diagnosis was delayed because of pain referral to the knee. The mean duration from the onset of symptoms to diagnosis of osteoid osteoma was 20 months (range 3 to 48 months). Review of these 11 lesions indicates that they can be classified on the basis of their anatomical location: (a) distant to the knee; (b) periarticular; or (c) subarticular (intraarticular). It should be noted that initially only 5 of the 11 cases displayed characteristic x-ray findings; in the remaining 6 cases, diagnosis was dependent on positive 99mTc radionuclide bone scans, tomograms, and computerised tomography scans. Of the 9 patients who underwent surgical resection of their lesions, all had complete relief of symptoms and all continued to be asymptomatic at follow-up evaluations.

Abstract
Choledochal sphincter stenosis was demonstrated in 37 of 90 patients with pancreas divisum. In 21 of the patients, stenosis was diagnosed during ERCP by endoscopic calibration of the choledochal sphincter, delayed drainage of contrast material from the bile duct, or a dilated common duct with or without elevation of the serum alkaline phosphatase level. In 12 patients, stenosis was diagnosed during endoscopic manometry with the demonstration of elevated basal choledochal sphincter pressures. Stenosis was initially diagnosed during surgery in four patients. Common duct diameters were normal in all patients who had not had cholecystectomy. Choledochal sphincter stenosis was confirmed in all patients who subsequently underwent sphincteroplasty. The surgical approach to patients with pancreas divisum and intractable obstructive pain should include sphincteroplasty of both the major and minor sphincters rather than the minor sphincter alone.

Abstract
Identical, thyroxine containing tryptic peptides have been isolated from digests of bovine, ovine and procine thyroglobulins. This 19 residue hormone containing sequence, NH2-Asn-Ile-Phe-Glu-T4-Gln-Val-Asp-Ala-Gln-Pro-Leu-Arg-Pro-Cys-Glu-Leu-G in-Arg- COOH, is completely conserved across these three species, and it represents a principal site of thyroxine synthesis. HPLC maps of tryptic digests of the thyroglobulins have been monitored at several wavelengths and suggest that, in each case, only a small number of tryptic peptides are iodinated in vivo and that an even smaller number of tryptic peptides contain thyroid hormone. These data are consistent with a high degree of selectivity in iodination of tyrosines within thyroglobulin and the subsequent coupling of these selected tyrosines to form thyroid hormone.

Abstract
This study subjects the Coppoletta-Wolbach data of normal organ weights of children from birth to 12 years of age to statistical analysis, producing a set of curves that show the linear regression of organ weight versus age for each set of weights plus, for each organ, the 75%, 80%, 90%, 95%, and 99% confidence bands for single new values.
