Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry.

Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Abstract
Background Psychotherapy of mother-child dyads is an intervention which was developed to prevent maltreatment and negative children’s development. There is a lack of good-quality research investigating psychotherapeutic interventions and social care for mothers at high-risk living in Mother-Child Facilities in Germany. The present randomized controlled pilot trial (RCT) aimed to evaluate the need for parent-infant psychotherapy (PIP) and to explore its impact on the mother-infant relationship. Primary feasibility objectives were recruitment and attrition, with potential efficacy defined as the secondary feasibility objective. Methods This pilot RCT focused on (young) mothers with cumulative risk factors and their infants under 7 months of age living in Mother-Child Facilities. N=32 mother-child dyads were randomly allocated to PIP or Care as usual (CAU). Outcomes were assessed at baseline, 3 months, and 6 months of intervention. The primary potential efficacy outcome was maternal sensitivity. Secondary outcomes were maternal mental health problems, reflective functioning, parenting stress, personality organization, infant’s development, and attachment. Results At baseline, all mothers showed low levels of emotional availability, but results revealed improvements in sensitivity, mental health problems, stress, and depressive symptomatology favoring PIP after 6 months. Positive developments in maternal sensitivity, a healthy aspect of mother-child interaction, were only found in the PIP group. Overall attrition was high at 6 months. Some evidence of fewer depressive symptoms and lower maternal distress after 6 months of PIP-intervention exists that did not reach significance. Conclusion Findings revealed improvements in the mother’s well-being for both groups, but PIP had a higher impact on the mother-child dyad. In sum, there is some evidence that PIP may represent an effective intervention offer besides the social and pedagogical support in these facilities, but further research is demanded.

Abstract
BACKGROUND After the birth of a child, many mothers and fathers experience postpartum mental disorders like depression, anxiety, obsessive-compulsive disorder, stress or other illnesses. This endangers the establishment of a secure attachment between the children and their primary caregivers. Early problems in parent-child interaction can have adverse long-term effects on the family and the child's well-being. In order to prevent a transgenerational transmission of mental disorders, it is necessary to evaluate psychotherapeutic interventions that target psychologically burdened parents of infants or toddlers. The aim of this trial is to investigate the efficacy of Parent-Infant-Psychotherapy (PIP) for mothers with postpartum mental disorder and their infants (0-12 months). METHODS/DESIGN In this open, randomized controlled intervention trial 180 mother-infant-dyads will be included and randomly allocated to 12 sessions of PIP or care as usual. The interventions take place either in inpatient adult psychiatric departments or in outpatient settings with home visits. The primary outcome is the change in maternal sensitivity assessed by the Sensitivity subscale of the Emotional Availability Scale (EAS) through videotaped dyadic play-interactions after 6 weeks. Secondary outcomes are maternal psychopathology, stress, parental reflective functioning, infant development and attachment after 6 weeks and 12 months. In addition, maternal attachment (AAI) and reflective functioning (AAI) will be analyzed as potential moderators, and resource usage in the German health system as well as associated costs will be evaluated. DISCUSSION There is increasing demand for well-controlled studies on psychotherapeutic interventions in the postpartum period that do not only focus on particular risk groups. This randomized controlled trial (RCT) represents one of the first studies to investigate the efficacy of PIP in inpatient psychiatric departments and outpatient care centers in Germany. The results will fill knowledge gaps on the factors contributing to symptom reduction in postpartum mental disorders and improvements in mother-child relationships and help in developing preventive and therapeutic strategies for the fragmented German health care system.

Abstract
Porphyromonas gingivalis and Tannerella forsythia secrete proteases, gingipains and KLIKK-proteases. In addition, T. forsythia produces a serpin (miropin) with broad inhibitory spectrum. The aim of this pilot study was to determine the level of expression of miropin and individual proteases in vivo in periodontal and peri-implant health and disease conditions. Biofilm and gingival crevicular fluid (GCF)/ peri-implant sulcular fluid (PISF) samples were taken from healthy tooth and implant sites (n = 10), gingivitis and mucositis sites (n = 12), and periodontitis and peri-implantitis sites (n = 10). Concentration of interleukin-8 (IL-8), IL-1β and IL-10 in GCF was determined by enzyme-linked immunosorbent assay. Loads of P. gingivalis and T. forsythia and the presence of proteases and miropin genes were assessed in biofilm by quantitative PCR, whereas gene expression was estimated by quantitative RT-PCR. The presence of P. gingivalis and T. forsythia, as well as the level of IL-8 and IL-1β, were associated with disease severity in the periodontal and peri-implant tissues. In biofilm samples harboring T. forsythia, genes encoding proteases were found to be present at 72.4% for karilysin and 100% for other KLIKK-protease genes and miropin. At the same time, detectable mRNA expression of individual genes ranged from 20.7% to 58.6% of samples (for forsylisin and miropsin-1, respectively). In comparison with the T. forsythia proteases, miropin and the gingipains were highly expressed. The level of expression of gingipains was associated with those of miropin and certain T. forsythia proteases around teeth but not implants. Cumulatively, KLIKK-proteases and especially miropin, might play a role in pathogenesis of both periodontal and peri-implant diseases.

Abstract
Silicate associated osteoporosis (SAO) was diagnosed post mortem in an adult horse with the shortest documented exposure to cytotoxic silicates of 2 years. The horse was evaluated for a 6-months history of progressive back tenderness and acute onset of lameness. The horse had a marked (4/5) [American Association of Equine Practitioners scale] left forelimb lameness, moderate (2/5) hindlimb ataxia and weakness, and cervical pain upon palpation. Physical examination did not reveal clinical skeletal deformities or respiratory compromise. Radiographs revealed widespread, discrete, sharply delineated, osteolytic lesions in the skull, vertebral column, ribs, scapulae and middle phalanx (P2) of the left forelimb and a diffuse bronchointerstitial lung pattern. The presumptive clinical diagnosis was widespread, metastatic osteolytic neoplasia. Due to the poor quality of life and grave prognosis, the horse was humanely euthanised. Post mortem examination revealed pulmonary silicosis in the lungs and hilar lymph nodes and osteolytic lesions with numerous, large osteoclasts and disorganised bone remodeling both consistent with SAO. SAO should be included as a differential diagnosis for horses with widespread, multifocal, discrete osteolysis and history of exposure to endemic regions with possible cytotoxic silicate inhalation. Exposure time of 2 years is potentially sufficient to develop SAO.

Abstract
Registry data on invasive cervical cancers (n = 1,274) from four major hospitals (1984-2012) were analysed to determine their value for informing local service delivery in Australia. The methodology comprised disease-specific survival analyses using Kaplan-Meier product-limit estimates and Cox proportional hazards models and treatment analyses using logistic regression. Five- and 10-year survivals were 72% and 68%, respectively, equating with relative survival estimates for Australia and the USA. Most common treatments were surgery and radiotherapy. Systemic therapies increased in recent years, generally with radiotherapy, but were less common for residents from less accessible areas. Surgery was more common for younger women and early-stage disease, and radiotherapy for older women and regional and more advanced disease. The proportion of glandular cancers increased in-step with national trends. Little evidence of variation in risk-adjusted survival presented over time or by Local Health District. The study illustrates the value of local registry data for describing local treatment and outcomes. They show the lower use of systemic therapies among residents of less accessible areas which warrants further investigation. Risk-adjusted treatment and outcomes did not vary by socio-economic status, suggesting equity in service delivery. These data are important for local evaluation and were not available from other sources.

Abstract
Monitoring screening mammography effects in small areas is often limited by small numbers of deaths and delayed effects. We developed a risk score for breast cancer death to circumvent these limitations. Screening, if effective, would increase post-diagnostic survivals through lead-time and related effects, as well as mortality reductions. Linked cancer and BreastScreen data at four hospitals (n = 2,039) were used to investigate whether screened cases had higher recorded survivals in 13 small areas, using breast cancer deaths as the outcome (M1), and a risk of death score derived from TNM stage, grade, histology type, hormone receptor status, and related variables (M2). M1 indicated lower risk of death in screened cases in 12 of the 13 areas, achieving statistical significance (p < .05) in 5. M2 indicated lower risk scores in screened cases in all 13 areas, achieving statistical significance in 12. For cases recently screened at diagnosis (<6 months), statistically significant reductions applied in 8 areas (M1) and all 13 areas (M2). Screening effects are more detectable in small areas using these risk scores than death itself as the outcome variable. An added advantage is the application of risk scores for providing a marker of screening effect soon after diagnosis.

Abstract
The mechanisms governing how the hippocampus selects neurons to exhibit place fields are not well understood. A default assumption in some previous studies was the uniform random draw with replacement (URDWR) model, which, theoretically, maximizes spatial "pattern separation", and predicts a Poisson distribution of the numbers of place fields expressed by a given cell per unit area. The actual distribution of mean firing rates exhibited by a population of hippocampal neurons, however, is approximately exponential or log-normal in a given environment and these rates are somewhat correlated across multiple places, at least under some conditions. The advantage of neural activity-dependent immediate-early gene (IEG) analysis, as a proxy for electrophysiological recording, is the ability to obtain much larger samples of cells, even those whose activity is so sparse that they are overlooked in recording studies. Thus, a more accurate representation of the activation statistics can potentially be achieved. Some previous IEG studies that examined behavior-driven IEG expression in CA1 appear to support URDWR. There was, however, in some of the same studies, an under-recruitment of dentate gyrus granule cells, indicating a highly skewed excitability distribution, which is inconsistent with URDWR. Although it was suggested that this skewness might be related to increased excitability of recently generated granule cells, we show here that CA1, CA3, and subiculum also exhibit cumulative under-recruitment of neurons. Thus, a highly skewed excitability distribution is a general principle common to all major hippocampal subfields. Finally, a more detailed analysis of the frequency distributions of IEG intranuclear transcription foci suggests that a large fraction of hippocampal neurons is virtually silent, even during sleep. Whether the skewing of the excitability distribution is cell-intrinsic or a network phenomenon, and the degree to which this excitability is fixed or possibly time-varying are open questions for future studies. © 2016 Wiley Periodicals, Inc.

Abstract
Data from registries at four major public hospitals in South Australia indicate increased 5-year disease-specific survivals for colorectal cancer from 48% to 63% between 1980-1986 and 2005-2010. For 80+ year olds, the increase was smaller, from 47% to 52%. Risk of case fatality halved overall, adjusting for age, gender, stage, differentiation and sub-site. Patients aged 80+ years had a lower risk reduction of about a third (hazards ratio: 0.69; 95% confidence limits, 0.52-0.92). Percentages having surgery and other specified treatments were lower for 80+ year olds than younger cases, although increases in treatment intensity occurred in this age range during 1980-2010, as seen in younger ages, in accordance with guidelines. The study illustrates the important feedback clinical registries can provide to clinicians on care patterns and outcomes in their hospital settings. Feedback can be the subject of local deliberations on how to achieve the best outcomes, including in the elderly by considering the best trade-offs between optimal cancer care and accommodations for co-morbidity and frailty. Clinical registry data can be used in comparative effectiveness research in local settings where there are sufficient case numbers.

Abstract
BACKGROUND As a result of the actual amendment of the German transplantation law, every citizen will be regularly asked by health insurance companies about his attitude towards post-mortem organ donation--without the obligation to decide. The aim is to increase the willingness of donations as well as the availability of organs. Therefore, we investigated the level of information of students at the University of Regensburg and their agreement to organ transplantation regarding an informed consent. METHODS Using an interdisciplinary developed questionnaire (Medicine, Theology, Educational Science) the level of information concerning process and possibilities of organ donation, the possession of an organ donor card, as well as the active or passive consent to donate organs was investigated. RESULTS Out of 1225 respondents 31.5% had an organ donor card, 49.1% wanted to donate organs, 32.1% were unsure. 98% generally favoured organ donation. However, serious information deficits about brain death were identified: 37.4% did not know that brain death is a prerequisite for a post-mortem organ donation, 18% thought brain death is reversible, 52.7% were not aware of the necessity of intensive medical care. Furthermore, providing information about other potential donor organs including lungs, pancreas, small intestine, and tissue is required. CONCLUSION Health insurance companies and responsible authorities need to close the identified gaps in knowledge in order to achieve "informed" consent with organ donation, which might increase the availability and number of donor organs.

Abstract
OBJECTIVE The risk of arterial hypertension and subsequent cardiovascular disease morbidity and mortality increases with low socio-economic status (SES). Even small differences in blood pressure, whether untreated or despite treatment, account for this substantial difference. Most of the increased risk in the low socio-economic group is due to traditional cardiovascular risk factors such as overweight and obesity, alcohol consumption and a sedentary life style. Intense treatment of arterial hypertension has been shown to overcome these prognostic inequalities. Therefore, drugs with high efficacy, optimal treatment adherence and a low potential for drug-related side effects are needed in order to reduce the cardiovascular risk burden of patients with a low SES. The angiotensin receptor blocker (ARB) olmesartan will be used to investigate the effectiveness of this drug in different socio-economic classes. RESEARCH DESIGN AND METHODS The LEO (Long-term Effectiveness of Olmesartan in different Socioeconomic groups) study is a large observational long-term study which has been set up to test the effectiveness of olmesartan within this context. The study has a matched-pairs design (1403 patients in both the low and the high socio-economic classes). MAIN OUTCOME MEASURES The LEO study will test whether this regimen can reduce the SES-related difference in long-term blood pressure control and compliance in the low SES population. CONCLUSIONS The study may generate valuable information about the antihypertensive effectiveness of olmesartan alone or in combination with hydrochlorothiazide in different socio-economic classes. It will further test whether the drug helps to reduce the inherent inequalities in cardiovascular prognosis between different socio-economic groups. CURRENT STATUS The study commenced in July 2007. Results are anticipated in December 2008.

BACKGROUND Structural neuroimaging studies have consistently shown a pattern of extra-hippocampal atrophy in patients with left and right drug-refractory medial temporal lobe epilepsy (MTLE). However, it is not yet completely understood how extra-hippocampal atrophy is related to hippocampal atrophy. Moreover, patients with left MTLE often exhibit more intense cognitive impairment, and subtle brain asymmetries have been reported in patients with left MTLE versus right MTLE but have not been explored in a controlled study. OBJECTIVES To investigate the association between extra-hippocampal and hippocampal atrophy in patients with MTLE, and the effect of side of hippocampal atrophy on extra-hippocampal atrophy. METHODS Voxel-based morphometry analyses of magnetic resonance images of the brain were performed to determine the correlation between regional extra-hippocampal grey matter volume and hippocampal grey matter volume. The results from 36 patients with right and left MTLE were compared, and results from the two groups were compared with those from 49 healthy controls. RESULTS Compared with controls, patients with MTLE showed a more intense correlation between hippocampal grey matter volume and regional grey matter volume in locations such as the contralateral hippocampus, bilateral parahippocampal gyri and frontal and parietal areas. Compared with right MTLE, patients with left MTLE exhibited a wider area of atrophy related to hippocampal grey matter loss, encompassing both the contralateral and ipsilateral hemispheres, particularly affecting the contralateral hippocampus. CONCLUSIONS Our results suggest that left hippocampal atrophy is associated with a larger degree of extra-hippocampal atrophy. This may help to explain the more intense cognitive impairment usually observed in these patients.

Abstract
The aim of the present paper is to compare the results obtained using two osteosynthesis systems developed for the surgical treatment of unstable fractures of the trochanteric region of the femur: the proximal femoral nail (PFN) and the dynamic hip screw (DHS) with trochanteric butt-press plate (TBPP). From December 1997 to November 2000, 173 patients with instable trochanteric fractures (type 31 A-2 and A-3 according to the AO-classification) had osteosynthesis by PFN (n = 122) or DHS/TBPP (n = 51). The average patient age was 74 years (range 27 to 98). No significant differences between the two study groups were observed with regard to age, sex, and rate of fracture types. At an average follow-up of 17 months the radiological and clinical outcome according to the score of "Merle d'Aubigné" was analysed in 61 % of all patients. All fractures were healed with no difference in functional outcome between the two groups. In the case of PFN 17.2 % revisions were necessary and in the case of DHS with TBPP 21.6 %. A shorter operation time (43 vs. 61 min) and a considerable shorter in-patient stay (20 vs. 24 days) were common with PFN. Full-weight-bearing immediately after the osteosynthesis was possible for 98 % of the PFN patients and 81 % of the DHS/TBPP patients. The DHS/TBPP osteosynthesis in instable trochanteric fractures is associated with a higher incidence of complications. Therefore we recommend to treat instable fractures of the trochanteric region with the PFN.

Abstract
We describe octopamine-immunoreactive somata and their projections in the pro- meso-, meta- and pregenital abdominal-ganglia of locusts. Immunoreactive midline somata were identified as dorsal- and ventral- unpaired median (DUM- and VUM-, respectively) neurones due to their: characteristic large size and positions of somata, primary neurites in DUM-tracts giving rise to T-junctions, and bilaterally projecting axons. In the prothoracic ganglion there are most likely 8 such cells; in the meso- and metathoracic, some 20 each; and in each individual pregenital abdominal ganglion, typically 3. All appear to project to peripheral nerves and their numbers correspond to the number of peripherally projecting DUM-cells identified to date in each ganglion. We suggest that probably all peripherally projecting DUM-cells are octopaminergic in the examined ganglia. Presumptive DUM-interneurones are not octopamine-immunoreactive, but, confirming other studies, are shown to label with an antiserum to gamma-amino butyric acid (GABA). Other octopamine-immunoreactive neurones include a pair of midline, prothoracic, anterior medial cells, not necessarily DUM-cells, and a pair of ventral lateral somata in each thoracic- and the first abdominal ganglion. The latter project intersegmentally in ventral tracts. Intersegmentally projecting octopamine-immunoreactive fibers in dorsal tracts probably arise from a prothoracic DUM-cell, which leaves through suboesophageal nerves, or descending suboesophageal DUM-cells. Thus, the octopamine-immunoreactive system of thoracic and pregenital abdominal ganglia in locust comprises all peripherally projecting DUM-cells and a plurisegmental network.

Abstract
Voltage-activated, Ca2+-sensitive K+ channels (BK or maxi K,Ca channels) play a major role in the control of neuronal excitability. We have cloned pSlo, the BK channel alpha subunit of the cockroach Periplaneta americana. The amino acid sequence of pSlo shows 88% identity to dSlo from Drosophila. There are five alternatively spliced positions in pSlo showing differential expression in various tissues. A pSlo-specific antibody prominently stained the octopaminergic dorsal unpaired median (DUM) neurons and peptidergic midline neurons in Periplaneta abdominal ganglia. HEK293 cells expressing pSlo exhibit K+ channels of 170 pS conductance. They have a tendency for brief closures, exhibit subconductance states and show slight inward rectification. Activation kinetics and voltage dependence are controlled by cytoplasmic [Ca2+]. In contrast to dSlo, pSlo channels are sensitive to charybdotoxin and iberiotoxin. Mutagenesis at two positions (E254 and Q285) changed blocking efficacy of charybdotoxin. In contrast to pSlo expressed in HEK293 cells, native IbTx-sensitive K,Ca currents in DUM and in peptidergic neurons, exhibited rapid, partial inactivation. The fast component of the K,Ca current partly accounts for the repolarization and the early after-hyperpolarization of the action potential. By means of Ca2+-induced repolarization, BK channels may reduce the risk of Ca2+ overload in cockroach neurons. Interestingly, the neurons expressing pSlo were also found to express taurine, a messenger that is likely to limit overexcitation by an autocrine mechanism in mammalian central neurons.

Abstract
This paper gives a summary of a project to characterize a tobacco aquaporin. The cDNA and gene, including the 5' upstream region, for the tobacco aquaporin NtAQP1 has been isolated and the encoded protein characterized. The significance of promoter regions for an abscisic acid- and gibberellic acid-induced gene expression could be restricted to a region between -1450 and -1112 upstream of the transcription start point by transient transformation of a bicistronic vector into tobacco protoplasts. NtAQP1 expression in tobacco plants was found to be elevated in flowers, stems and roots. In roots, the protein was detected close to xylem vessels in pitch-like structures. Studies with a NtAQP1-GFP fusion indicated a plasma membrane location. For a functional analysis, the cDNA was expressed in Xenopus oocytes. NtAQP1 was found to be a heavy metal-insensitive aquaporin with additional permeability for glycerol. Mutation of a threonine at position 233 to a cysteine transformed NtAQP1 into a heavy metal-sensitive aquaporin.

Abstract
The aim of this study was to assess the trapeziometacarpal joint kinematics from in vivo measurements, both quantifying the ranges of motion and suggesting a suitable joint model. A motion analysis system has been used to collect the spatial trajectories of markers, glued respectively on the thumb and on the hand's palm. A rigorous protocol was set up to make sure of the trapezoid bone's fixity relatively to the hand, and then to be able to characterize the movement of the first metacarpus with respect to the trapezium. The ranges of motion have been measured on two distinct movements: circumduction and flexion-extension, and different types of joints: healthy, pathological and prosthetic. The joint axes of rotation (for flexion-extension and ante-retroposition movements) have been determined on healthy subjects. The computation of rotation amplitudes and positions of joint axes was based upon the finite helical axis concept, which degenerates into finite rotation axis when translations can be neglected. Both the measurement protocol and the calculation method have been validated by comparing the computed joint center with that measured on a radiography, in the case of a spherical prosthesis. The ranges of motion obtained on the healthy subject series were consistent with values published by other authors. Comparisons have been realized between these reference joints and different cases: arthrodesis, arthrosis and prosthesis. The determination of rotation axes of a normal joint has lead to a generalized cardan joint, i.e. two non perpendicular converging rotation axes.

Abstract
A large number of myostimulatory neuropeptides from neurohaemal organs of the American cockroach have been described since 1989. These peptides, isolated from the retrocerebral complex and abdominal perisympathetic organs, are thought to be released as hormones. To study the coordinated action of these neuropeptides in the regulation of visceral muscle activity, it might be necessary to include myoinhibitors as well, however, not a single myoinhibitory neuropeptide of the American cockroach has been described so far. To fill this gap, we describe the isolation of LMS (leucomyosuppressin) and Pea-MIP (myoinhibitory peptide) from neurohaemal organs of the American cockroach. LMS was very effective in inhibiting phasic activity of all visceral muscles tested. It was found in the corpora cardiaca of different species of cockroaches, as well as in related insect groups, including mantids and termites. Pea-MIP which is strongly accumulated in the corpora cardiaca was not detected with a muscle bioassay system but when searching for tryptophane-containing peptides using a diode-array detector. This peptide caused only a moderate inhibition in visceral muscle assays. The distribution of Pea-MIP in neurohaemal organs and cells supplying these organs with Pea-MIP immunoreactive material, is described. Additionally to LMS and Pea-MIP, a member of the allatostatin peptide family, known to exhibit inhibitory properties in other insects, was tested in visceral muscle assays. This allatostatin was highly effective in inhibiting spontaneous activity of the foregut, but not of other tested visceral muscles of the American cockroach.

Abstract
The periviscerokinins of Periplaneta americana (Pea-PVKs) were the first neuropeptides directly isolated from perisympathetic organs (PSOs), neurohemal swellings of the transverse and median nerves of insects. It has been demonstrated that Pea-PVK-1 release can be induced from the abdominal PSOs of P. americana by in vitro depolarization. A myotropic effect of Pea-PVK-1 on the hyperneural muscle is restricted to blattid cockroaches, whereas proctolin induces contractions of this muscle in all cockroach species investigated. The location and morphology of Pea-PVK-1-like immunoreactive neurons in species of different cockroach taxa are very similar to those previously described for P. americana. Pea-PVK-1-like immunoreactivity is restricted to cells of the abdominal ganglia which constitute a neurohemal system and project via the median nerve to the abdominal PSOs. Despite interspecific differences in the topography of the transverse nerves of the terminal ganglion, Pea-PVK-1-like immunoreactive fibers always innervate transversal nerves VII and VIII of the terminal ganglion. The results suggest that PVKs act as neurohormones throughout the cockroaches, although they may have different effect(s) depending on the species.

Abstract
PURPOSE To determine the type and prevalence of epithelial abnormalities in the intermediate postoperative period after penetrating keratoplasty and to define the donor and recipient variables that influence the status of the graft epithelium. DESIGN Prospective cohort study. METHODS We prospectively followed the clinical course of 80 patients after penetrating keratoplasty. We monitored the status of the corneal epithelium for 3 months after surgery using slit-lamp biomicroscopy and fluorescein staining of the epithelium. Donor characteristics, recipient preoperative and postoperative variables, and postoperative medications were recorded. Epithelial abnormalities were analyzed against these variables by using univariate and combined statistical models to determine the impact of each variable on postoperative epithelial pathology. Main outcome measures included punctate keratopathy, macro-epithelial defects, hurricane keratopathy, rim defects, and filamentary keratopathy. RESULTS Sixty-three percent of all patient visits demonstrated punctate epithelial keratopathy (PEK). Hurricane keratopathy (51%) and filamentary keratopathy (14%) constituted the next most commonly observed abnormalities. Older recipient age and the use of topical antibiotics were associated with a higher prevalence of punctate epithelial keratopathy. The odds ratio (OR) for a 1-year increase in age is 1.0276 (95% CI, 1.1013-1.0442), and the OR for using topical antibiotics is 6.9028 (95% CI, 3.1506-15.1239). Use of topical ofloxacin and increased time after surgery were associated with lower prevalence of punctate keratopathy; ORs were 0.9806 (95% CI, 0.9736-0.9876) and 0.3662 (95% CI, 0.1688-0.7943), respectively. Decreased corneal sensation and the presence of anterior blepharitis preoperatively were associated with an increase in hurricane keratopathy; ORs were 8.8265 (CI, 2.3837-32.6835) and 3.2815 (CI, 1.7388-6.1931), respectively. Total storage time for the donor material was also associated with an increased prevalence of hurricane keratopathy (OR, 1.0316; CI, 1.0052-1.0220). Patients with rim defects and macro-epithelial defects were more likely to have antibiotic and topical lubrication prescribed. No specific variable was found to have a significant association with filamentary keratopathy, except possibly for death-to-preservation time, which had a P value of .0587. CONCLUSIONS Surface keratopathy is one of the most common complications of keratoplasty. Our study demonstrates that older age, preoperative lid disease, and decreased preoperative corneal sensation appear to increase the probability of clinically significant epithelial surface abnormalities after keratoplasty. Recognition of these risk factors in advance of surgery will alert the surgeon to the need for appropriate management.

Abstract
Mendelian tumour syndromes are caused by rare mutations, which usually lead to protein inactivation. Few studies have determined whether or not the same genes harbour other, more common variants, which might have a lower penetrance and/or cause mild disease, perhaps indistinguishable from sporadic disease and accounting for a considerable proportion of the unexplained inherited risk of tumours in the general population. Germline variants at the APC locus are excellent candidates for explaining why some individuals are predisposed to colorectal adenomas, but do not have the florid phenotype of familial adenomatous polyposis. We have screened 164 unrelated patients with 'multiple' (3-100) colorectal adenomas for germline variants throughout the APC gene, including promoter mutations. In addition to three Ashkenazi patients with I1307K, we found seven patients with the E1317Q variant. E1317Q is significantly associated with multiple colorectal adenomas (OR = 11. 17, 95% CI = 2.30-54.3, p < 0.001), accounting for approximately 4% of all patients with multiple colorectal adenomas. In addition, four patients with truncating APC variants in exon 9 or in the 3' part of the gene were identified. Germline APC variants account for approximately 10% of patients with multiple adenomas. Unidentified predisposition genes almost certainly exist. We argue that it is worthwhile to screen multiple adenoma patients for a restricted number of germline APC variants, namely the missense changes E1317Q and I1307K (if of Ashkenazi descent), and, if there is a family history of colorectal tumours, for truncating mutations 5' to exon 5, in exon 9 and 3' to codon 1580.

Abstract
There is growing evidence that metabolic enzymes may act as multifunctional proteins performing diverse roles in cellular metabolism. Among these functions are the RNA-binding activities of NAD(+)-dependent dehydrogenases. Previously, we have characterized the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as an RNA-binding protein with preference to adenine-uracil-rich sequences. In this study, we used GST-GAPDH fusion proteins generated by deletion mutagenesis to search for the RNA binding domain. We established that the N-terminal 43 amino acid residues of GAPDH, which correspond to the first mononucleotide-binding domain of the NAD(+)-binding fold is sufficient to confer RNA-binding. We also provide evidence that this single domain, although it retains most of the RNA-binding activity, loses sequence specificity. Our results suggest a molecular basis for RNA-recognition by NAD(+)-dependent dehydrogenases and (di)nucleotide-binding metabolic enzymes that had been reported to have RNA-binding activity with different specificity. To support this prediction we also identified other members of the family of NAD(+)-dependent dehydrogenases with no previous history of nucleic acid binding as RNA binding proteins in vitro. Based on our findings we propose the addition of the NAD(+)-binding domain to the list of RNA binding domains/motifs.

Abstract
Various Arabidopsis thaliana mutants with defects in phytohormone signal transduction or the reception of light were analysed with regard to their stomatal response in a red, red/blue light irradiation programme. Stomatal response to light was detected with a customized gas exchange measurement device, optimized for the small model plant. Small transpiration-kinetic variations of the two wild-type lines Columbia (Col) and Landsberg erecta (Ler) were observed. A comparison of the mutant lines to the respective wild type revealed significant differences for the phytochrome A (phyA-103), the abscisic acid insensitive (aba3-2) and the auxin resistant (axr1-3) mutant. Furthermore, the zeaxanthin-less mutant line npq1-2 showed no alterations in stomatal response to light.

Abstract
Insect neuropeptides are produced in less than 1% of the cells of the central nervous system. Despite this, they are important messenger molecules which influence nearly all physiological processes, including behaviour. They can act as transmitters, modulators and classical hormones, and often exhibit pleiotropic functions when released into the haemolymph. The large number of neuropeptides that has been identified from some of the model organisms among insects underlines the complexity of the neurosecretory system; studies about the coordinated actions of these substances are in their preliminary stages. Recent advances in insect neuropeptide research will be reviewed here, concentrating on the distribution of multiple peptide forms in the central nervous system and adjacent neurohaemal organs, and the role of neuropeptides in eclosion behaviour.

Abstract
FXPRLamide (pyrokinin) distribution in the central nervous system and major neurohaemal organs of the American cockroach and related cockroach species was investigated using immunocytochemistry and MALDI-TOF mass spectrometry. Six isoforms (Pea-PK-1 through -6) were found in different neurohaemal release sites. Pea-PK-1-4 and Pea-PK-6 are all stored in the retrocerebral complex and are all produced in cells located in both the suboesophageal ganglion (SOG) and the tritocerebrum. These pyrokinins were found to be concentrated in and around the corpora allata. No other known peptides were detectable in such high concentrations in this neurohaemal organ. They reach the corpora cardiaca/allata via the nervi corporis cardiaci-1 (NCC-1), NCC-3, and nervi corporis allati-2 (NCA-2). Abdominal perisympathetic organs contained only Pea-PK-5 and low quantities of the sequence-related Pea-PK-6. Neither Pea-PK-5 nor -PK-6 was detected in thoracic perisympathetic organs. It is likely that the expression of pyrokinins in the central nervous system is tagma (body region)-specific. Pea-PK-6 was identified during this study as follows: Ser-Glu-Ser-Glu-Val-Pro-Gly-Met-Trp-Phe-Gly-Pro-Arg-Leu-NH(2).

Abstract
The unicellular green alga Haematococcus pluvialis Flotow is known for its massive accumulation of ketocarotenoids under various stress conditions. Therefore, this microalga is one of the favored organisms for biotechnological production of these antioxidative compounds. Astaxanthin makes up the main part of the secondary carotenoids and is accumulated mostly in an esterified form in extraplastidic lipid vesicles. We have studied phytoene desaturase, an early enzyme of the carotenoid biosynthetic pathway. The increase in the phytoene desaturase protein levels that occurs following induction is accompanied by a corresponding increase of its mRNA during the accumulation period, indicating that phytoene desaturase is regulated at the mRNA level. We also investigated the localization of the enzyme by western-blot analysis of cell fractions and by immunogold labeling of ultrathin sections for electron microscopy. In spite of the fact that secondary carotenoids accumulate outside the chloroplast, no extra pathway specific for secondary carotenoid biosynthesis in H. pluvialis was found, at least at this early stage in the biosynthesis. A transport process of carotenoids from the site of biosynthesis (chloroplast) to the site of accumulation (cytoplasmatic located lipid vesicles) is implicated.

Abstract
We successfully isolated and identified the abundant neuropeptides of the abdominal perisympathetic organs of the American cockroach, including all myoactive compounds. Peptide sequence analysis and mass spectrometry of abundant substances that were not bioactive in different muscle assays yielded the following sequences: TDPLWQLPGAHLEQYLS-NH2 (Pea-YLS-amide), AFLTLTPGSHVDSYVEA-OH (Pea-VEAacid), and SDLTWTYQSPGDPTNSKN-OH (Pea-SKNacid). The given structures led to the conclusion of an unique neuropeptide pattern in abdominal perisympathetic organs. We confirmed this assumption with immunocytochemical studies, using antisera raised against different myotropic neuropeptides of the abdominal perisympathetic organs. Moreover, mass spectrometric methods, developed for the investigation of single neurohemal organs, confirmed the neuropeptide pattern in these organs.

Abstract
Atom efficient, multicomponent reactions that lead to high-value products from inexpensive starting materials are of both economic and ecological interest for industrial organic synthesis. alpha-Amino acids are amongst the most important compounds in chemistry and biology. As well as their biochemical significance as building blocks of peptides and proteins, alpha-amino acids are also becoming increasingly interesting as fine chemicals. Possibly one of the key reactions in the preparation of these compounds is transition metal catalyzed amidocarbonylation, where the alpha-amino acid framework is constructed in a single step from an aldehyde, an amide, and carbon monoxide. This article gives a current overview of transition metal catalyzed amidocarbonylation reactions used in the synthesis of alpha-amino acids derivatives. A classification and summary of the significant features of this three component reaction is first presented together, with an historical introduction. This section is followed by two sections on cobalt- and palladium-catalyzed amidocarbonylation. A discussion of the mechanism of each of the different amidocarbonylation variants form an introduction. Overviews on further synthetic development of the methodology, such as the domino reaction with an amidocarbonylation step and the expansion of the range of starting materials, form the main topics of both variants. The potential of the method is demonstrated with the help of examples of special synthetic utility (for example, the preparation of arylglycines). Finally, possibilities for future developments in transition metal catalyzed amidocarbonylation reactions are proposed on the basis of the current state of knowledge.

Abstract
Without solvent and in the open air, the hydroamination of phenylacetylene with aniline in the presence of [Ru(3)(CO)(12)]/NH(4)PF(6) proceeds with high regioselectivity [Eq. (1)]. Simple distillation gives a product with greater than 99 % purity in an excellent yield. The application of this method to a new two-component reaction gives the important class of substances: the quinolines.

Abstract
A highly specific polyclonal antiserum has been raised against periviscerokinin, the first neuropeptide isolated from the perisympathetic organs of insects (Predel et al. 1995). In this study, two different neuronal systems with periviscerokinin-like immunoreactivity were distinguished in the central nervous system of the American cockroach: (1) An intrinsic neuronal network, restricted to the head-thoracic region, was formed by intersegmental projecting neurons of the brain, suboesophageal ganglion and metathoracic ganglion. In addition, groups of local interneurons occurred in the proto- and tritocerebrum. (2) A typical neurohormonal system was stained exclusively in the abdomen; it was represented by abdominal perisympathetic organs which were supplied by three cell clusters located in each unfused abdominal ganglion. As revealed by nickel backfills, most neurons with axons entering the perisympathetic organs contained a periviscerokinin-like peptide. Immunoreactive fibres left the perisympathetic organs peripherally, innervated the hyperneural muscle and ran via the link nerves/segmental nerves to the heart and segmental vessels. All visceral muscles innervated by periviscerokinin-immunoreactive fibres were shown to be sensitive to periviscerokinin, whereas the hindgut gave no specific response to this peptide.

Abstract
This study was undertaken to reveal the quantitative distribution of the insect neuropeptide periviscerokinin-1 (Pea-PVK-1) in the central nervous system of Periplaneta americana and to demonstrate that neurons stained in a previous immunohistochemical study contain authentic Pea-PVK-1. For this, we combined ELISA, HPLC, and MALDI-TOF mass spectrometry. The high specificity of the used antiserum enabled the quantification of Pea-PVK-1 in unseparated tissue extracts. No cross-reactivities with other insect neuropeptides were detected in ELISA. Only two immunoreactive fractions, coeluting with synthetic Pea-PVK-1 in its oxidized and nonoxidized form, were found in HPLC-separated extracts of the brain, suboesophageal ganglion, metathoracic ganglion, second abdominal ganglion with or without perisympathetic organ, and terminal ganglion. By using MALDI-TOF mass spectrometry, we were able to confirm the existence of authentic Pea-PVK-1 in these fractions. The abdominal perisympathetic organs contained 6.3 pmol Pea-PVK-1 per animal; another 1.3 pmol were found in the abdominal ganglia. More than 90% of the total 8.2 pmol in the central nervous system was found in the abdominal ganglia and their perisympathetic organs. The corpora cardiaca and corpora allata did not contain immunoreactive material, suggesting that Pea-PVK-1 is not released by the cephalic neurohaemal system. The quantitative distribution of Pea-PVK-1 differs considerably from that of other known insect neuropeptides.
