Abstract
Accurate measurements of hip joint kinematics are essential for improving our understanding of the effects of injury, disease, and surgical intervention on long-term hip joint health. This study assessed the accuracy of conventional motion capture (MoCap) for measuring hip joint center (HJC) location and hip joint angles during gait, squat, and step-up activities while using dynamic biplane radiography (DBR) as the reference standard. Twenty-four young adults performed six trials of treadmill walking, six body-weight squats, and six step-ups within a biplane radiography system. Synchronized biplane radiographs were collected at 50 images per second and MoCap was collected simultaneously at 100 images per second. Bone motion during each activity was determined by matching digitally reconstructed radiographs, created from subject-specific CT-based bone models, to the biplane radiographs using a validated registration process. Errors in estimating HJC location and hip angles using MoCap were quantified by the root mean squared error (RMSE) across all frames of available data. The MoCap error in estimating HJC location was larger during step-up (up to 89.3 mm) than during gait (up to 16.6 mm) or squat (up to 31.4 mm) in all three anatomic directions (all p < 0.001). RMSE in hip joint flexion (7.2°) and abduction (4.3°) during gait was less than during squat (23.8° and 8.9°) and step-up (20.1° and 10.6°) (all p < 0.01). Clinical analysis and computational models that rely on skin-mounted markers to estimate hip kinematics should be interpreted with caution, especially during activities that involve deeper hip flexion.

Abstract
Importance Dry eye is a common ocular disease that can have substantial morbidity. Systematic reviews provide evidence for dry eye interventions and can be useful for patients, clinicians, and clinical guideline developers. Overviews of reviews use explicit and systematic methods to synthesize findings from multiple systematic reviews, but currently, there are no overviews of systematic reviews investigating interventions for dry eye. Objective To summarize the results of reliable systematic reviews of dry eye interventions and to highlight the evidence gaps identified. Evidence Review We searched the Cochrane Eyes and Vision US satellite database and included reliable systematic reviews evaluating dry eye interventions published from 2016 to 2022. We reported the proportion of systematic reviews that were reliable with reasons for unreliability. Critical and important outcomes from reliable systematic reviews were extracted and verified. Critical outcomes included dry eye-related patient-reported outcome measures. Results were synthesized from reliable systematic reviews to provide summaries of evidence for each intervention. Evidence for each intervention was defined as conclusive or inconclusive depending on whether high-certainty evidence across systematic reviews was available according to Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) criteria and whether findings reached statistical or clinical significance. Recommendations were made for further research. Findings Within the Cochrane Eyes and Vision US satellite database, 138 potentially relevant systematic reviews were identified, 71 were considered eligible, and 26 (37%) were assessed as reliable. Among reliable systematic reviews, no conclusive evidence was identified for any dry eye intervention. Inconclusive evidence suggested that environmental modifications, dietary modifications, artificial tears and lubricants, punctal occlusion, intense pulsed light therapy, vectored thermal pulsation therapy (Lipiflow), topical corticosteroids, topical cyclosporine A, topical secretagogues, and autologous serum may be effective. Only unreliable systematic reviews evaluated lifitegrast, oral antibiotics, and moisture chamber devices. Conclusions and Relevance This overview of systematic reviews found some evidence that dry eye interventions may be effective, but no conclusive evidence was available. The conduct and reporting of most systematic reviews for dry eye interventions warrant improvement, and reliable systematic reviews are needed to evaluate lifitegrast, oral antibiotics, and moisture chamber devices.

Abstract
BACKGROUND Acute respiratory distress syndrome (ARDS) is a severe and life-threatening condition that can occur in critically ill patients. Mechanical ventilation is a commonly used intervention with ARDS patients, but weaning patients off the ventilator can be challenging. An ARDSnet-like ventilator weaning protocol was implemented with the goal of reducing triggers for ventilator-associated events (VAEs). METHODS The implementation of the new protocol was used to complete a retrospective investigation of patient outcomes for 1,233 ventilator periods. Periods were included between April and December 2022 for any ventilated patient lasting at least 4 days. National Health Care Safety Network VAE criteria were used to surveille the patient data. Triggers were based on the positive end-expiratory pressure increases or fraction of inspired oxygen (FiO₂) increases. The preset weaning criteria was a reduction by 2 cmH2O per 24 hours. RESULTS Of the total 1,233 individual ventilator periods, VAE criteria were met in 10%. Of the total 126 periods with VAE, 39.2% met the criteria for appropriate protocol implementation. There was a statistically significant relationship between VAE identification and implementation of the protocol. CONCLUSIONS The implementation of a protocol for ventilator weaning affects the outcome of developing a VAE. The findings emphasize the importance of implementing the ARDS weaning protocol as a template to reduce the triggers for VAEs and improve overall patient outcomes.

Abstract
PURPOSE Small-fiber neuropathy (SFN) is known to be associated with Sjögren disease (SjD), and in vivo corneal confocal microscopy can identify features compatible with SFN. Here, we performed a descriptive study to identify features of SFN of the corneal subbasal nerve plexus using in vivo confocal microscopy. METHODS We recruited 10 participants from the Sjögren's International Collaborative Clinical Alliance (SICCA), 1 new participant (in an effort to expand the SICCA cohort), and 22 healthy controls. All participants underwent slit-lamp examination and in vivo confocal microscopy of the central corneal subbasal nerve plexus centered about the central whorl to create a 30-image montage. Each image was analyzed with automated software (ACCmetrics, Manchester, United Kingdom) to produce 7 nerve metrics. We performed t-tests and age-adjusted regressions to make comparisons of nerve metrics between participants with SjD and healthy controls. RESULTS Most nerve metrics were significantly lower in participants with SjD compared with healthy controls. The mean corneal nerve fiber density was found to be 3.5 mm/mm 2 in participants with SjD compared with 10.6 mm/mm 2 in healthy controls (95% confidence interval, -8.4 to -0.93; P = 0.02). Within the 11 participants with SjD, 22 eyes were analyzed on confocal microscopy, and 16 of those eyes (from 9 individuals) did not have an identifiable central whorl. Within the 22 healthy controls, 22 eyes (right eye alone) were analyzed on confocal microscopy, and 21 of those eyes had an identifiable central whorl. CONCLUSIONS SjD exhibits lower corneal nerve metrics compared with healthy controls. These findings suggest that features compatible with SFN can distinguish SjD from healthy controls and may serve as a potential novel biomarker in identifying SjD.

Abstract
OBJECTIVES To understand the postmortem decision-making needs and preferences of parents of a stillborn. METHODS A qualitative content analysis was conducted. Patients who received stillbirth care at the University of Utah in the last 5 years, were 18 years of age or older, and English speakers, were invited to participate via an email and follow-up phone call. Participants were interviewed about their experiences, values, beliefs, decision-making experience regarding the postmortem examinations of their stillborn, and suggestions for how to assist their decision-making needs. RESULTS Nineteen participants who consented to one or more postmortem examination of their stillborn were interviewed. They expressed needing information, altruism, and/or a belief in science as reasons for consenting. The most common reason for declining was already knowing the stillbirth cause. Recommendations for a decision aid included a description of all stillbirth evaluation options, risks and benefits, and a timeline. CONCLUSION Participants had a variety of reasons for consenting to or declining postmortem examinations of their stillborn. Recommendations for a decision aid include a full description of each examination, the risks and benefits, and a timeline. PRACTICAL IMPLICATIONS An example decision aid was created from recommendations, which presents balanced information to help support couple's decision-making.

Abstract
One to two percent of couples suffer recurrent pregnancy loss and over 50% of the cases are unexplained. Whole genome sequencing (WGS) analysis has the potential to identify previously unrecognized causes of pregnancy loss, but few studies have been performed, and none have included DNA from families including parents, losses, and live births. We conducted a pilot WGS study in three families with unexplained recurrent pregnancy loss, including parents, healthy live births, and losses, which included an embryonic loss (<10 weeks' gestation), fetal deaths (10-20 weeks' gestation) and stillbirths (≥ 20 weeks' gestation). We used the Illumina platform for WGS and state-of-the-art protocols to identify single nucleotide variants (SNVs) following various modes of inheritance. We identified 87 SNVs involving 75 genes in embryonic loss (n = 1), 370 SNVs involving 228 genes in fetal death (n = 3), and 122 SNVs involving 122 genes in stillbirth (n = 2). Of these, 22 de novo, 6 inherited autosomal dominant and an X-linked recessive SNVs were pathogenic (probability of being loss-of-function intolerant >0.9), impacting known genes (e.g., DICER1, FBN2, FLT4, HERC1, and TAOK1) involved in embryonic/fetal development and congenital abnormalities. Further, we identified inherited missense compound heterozygous SNVs impacting genes (e.g., VWA5B2) in two fetal death samples. The variants were not identified as compound heterozygous SNVs in live births and population controls, providing evidence for haplosufficient genes relevant to pregnancy loss. In this pilot study, we provide evidence for de novo and inherited SNVs relevant to pregnancy loss. Our findings provide justification for conducting WGS using larger numbers of families and warrant validation by targeted sequencing to ascertain causal variants. Elucidating genes causing pregnancy loss may facilitate the development of risk stratification strategies and novel therapeutics.

Abstract
OBJECTIVES This study was designed to investigate the response to chemotherapy of supradiaphragmatic disease diagnosed by preoperative imaging. As secondary objectives, oncologic outcomes of patients affected by supradiaphragmatic disease and their pattern of recurrence were also evaluated. METHODS Data of consecutive patients with newly diagnosed FIGO stage IV (for supradiaphragmatic disease) epithelial ovarian cancer undergoing either primary debulking surgery or neoadjuvant chemotherapy plus interval debulking surgery between 2004 and 2021, were retrospectively collected. All patients were preoperatively evaluated by chest/abdominal CT scan or 18F-FDG PET/CT preoperatively and at follow-up to evaluate response to chemotherapy. At follow-up visits, site of recurrence diagnosed by imaging techniques was systematically recorded as it occurred. Progression-free and overall survival were measured by using Kaplan-Meier and Cox models. RESULTS A total of 130 patients was included in this study with a median (range) follow-up of 32.9 (12.8-176.7) months. Complete or partial response was achieved in most of the patients after 3 cycles (77.7%) and 6 cycles (85.4%) of chemotherapy. At follow-up, recurrence occurred in 96 (73.8%) patients and the main site of recurrence was abdomen only in 64 (66.7%) patients. At multivariate analysis, residual disease after surgery was the only variable influencing survival outcomes. CONCLUSIONS Supradiaphragmatic disease respond to chemotherapy in most patients affected by advanced EOC and recurrence mainly occurs in the abdomen. Results from this study confirms that abdominal optimal cytoreduction is the main surgical goal in the treatment of women affected by FIGO stage IV EOC.

Abstract
OBJECTIVE Short-term morbidity of placenta accreta spectrum (PAS) is well described, but few data are available regarding long-term outcomes and quality of life. We aimed to evaluate patient-reported outcomes after hysterectomy for PAS. STUDY DESIGN This is a prospective cohort study of women with risk factors for PAS who were enrolled antenatally. Exposed women were defined as those who underwent cesarean hysterectomy due to PAS. Unexposed women were those with three or more prior cesareans or placenta previa, but no PAS, who underwent cesarean delivery without hysterectomy. Two surveys were sent to patients at 6, 12, 24, and 36 months postpartum: (1) a general health questionnaire and (2) the SF-36, a validated quality of life survey. Aggregate scores for each questionnaire were calculated and responses were analyzed. RESULTS At 6 months postpartum, women with PAS were more likely to report rehospitalization (odds ratio [OR] 5.83, 95% confidence interval [CI] 1.40-24.3), painful intercourse (OR 2.50, 95% CI 1.04-6.02), and anxiety/worry (OR 3.77, 95% CI 1.43-9.93), but were not statistically more likely to report additional surgeries (OR 3.39, 95% CI 0.99-11.7) or grief and depression (OR 2.45, 95% CI 0.87-6.95). At 12 months, women with PAS were more likely to report painful intercourse, grief/depression, and anxiety/worry. At 36 months, women with PAS were more likely to report grief/depression, anxiety/worry, and additional surgeries. Women with PAS reported significantly lower quality of life in physical functioning, role functioning, social functioning, and pain at 6 months postpartum, but not in other quality of life domains. Decreased quality of life was also reported at 12 and 36 months in the PAS group. CONCLUSION Women with PAS are more likely to report ongoing long-term health issues and decreased quality of life for up to 3 years following surgery than those undergoing cesarean for other indications. KEY POINTS · Long-term placenta accreta spectrum data to guide peripartum patient education.. · This study addresses a critical knowledge gap.. · Women affected by PAS report long-term morbidity..

Abstract
Low temperature in winter depresses rates of photosynthesis, which, in evergreen plants, can exacerbate imbalances between light absorption and photochemical light use. Damage that could result from increased excess light absorption is minimized by the conversion of excitation energy to heat in a process known as energy dissipation, which involves the de-epoxidized carotenoids of the xanthophyll cycle. Overwintering evergreens employ sustained forms of energy dissipation observable even after lengthy periods of dark acclimation. Whereas most studies of photoprotective energy dissipation examine one or a small number of species; here, we measured the levels of sustained thermal energy dissipation of seventy conifer taxa growing outdoors under common-garden conditions at the Red Butte Garden in Salt Lake City, Utah, U.S.A. (forty nine taxa were also sampled for needle pigment content). We observed an extremely wide range of wintertime engagement of sustained energy dissipation; the percentage decrease in dark-acclimated photosystem II quantum efficiency from summer to winter ranged from 6 to 95%. Of the many pigment-based parameters measured, the magnitude of the seasonal decrease in quantum efficiency was most closely associated with the seasonal increase in zeaxanthin content expressed on a total chlorophyll basis, which explained only slightly more than one-third of the variation. We did not find evidence for a consistent wintertime decrease in needle chlorophyll content. Thus, the prevailing mechanism for winter decreases in solar-induced fluorescence emitted by evergreen forests may be decreases in fluorescence quantum yield, and wintertime deployment of sustained energy dissipation likely underlies this effect.

Abstract
Performing a heterogeneous catalysis with proteins is still a challenge. Herein, we demonstrate the importance of cross-linked crystals for sulfoxide oxidation by an artificial enzyme. The biohybrid consists of the insertion of an iron complex into a NikA protein crystal. The heterogeneous catalysts displays a better efficiency-with higher reaction kinetics, a better stability and expand the substrate scope compared to its solution counterpart. Designing crystalline artificial enzymes represents a good alternative to soluble or supported enzymes for the future of synthetic biology.

Abstract
Frontal top-down cortical neurons projecting to sensory cortical regions are well-positioned to integrate long-range inputs with local circuitry in frontal cortex to implement top-down attentional control of sensory regions. How adolescence contributes to the maturation of top-down neurons and associated local/long-range input balance, and the establishment of attentional control is poorly understood. Here we combine projection-specific electrophysiological and rabies-mediated input mapping in mice to uncover adolescence as a developmental stage when frontal top-down neurons projecting from the anterior cingulate to visual cortex are highly functionally integrated into local excitatory circuitry and have heightened activity compared to adulthood. Chemogenetic suppression of top-down neuron activity selectively during adolescence, but not later periods, produces long-lasting visual attentional behavior deficits, and results in excessive loss of local excitatory inputs in adulthood. Our study reveals an adolescent sensitive period when top-down neurons integrate local circuits with long-range connectivity to produce attentional behavior.

Abstract
OBJECTIVES The neutropenic murine thigh infection model was used to assess the effectiveness of IID572, a novel β-lactamase inhibitor, in rescuing piperacillin activity against bacterial strains expressing various β-lactamase enzymes. METHODS Mice (n = 4/group) were inoculated with Enterobacteriaceae or Staphylococcus aureus bacterial strains expressing a range of β-lactamases via intramuscular injection. Two hours after bacterial inoculation, subcutaneous treatment with piperacillin/IID572 or piperacillin/tazobactam every 3 h was initiated. Animals were euthanized via CO2 24 h after the start of therapy and bacterial cfu (log10 cfu) per thigh was determined, and the static dose was calculated. RESULTS In a dose-dependent manner, piperacillin/IID572 reduced the thigh bacterial burden in models established with Enterobacteriaceae producing class A, C and D β-lactamases (e.g. ESBLs, KPC, CMY-2 and OXA-48). Piperacillin/IID572 was also efficacious against MSSA strains, including one producing β-lactamase. Static doses of piperacillin/IID572 were calculable from animals infected with all strains tested and the calculated static doses ranged from 195 to 4612 mg/kg/day piperacillin, the active component in the combination. Of the 13 strains investigated, a 1 log10 bacterial reduction was achieved for 9 isolates and a 2 log10 reduction was achieved for 3 isolates; piperacillin/tazobactam was not efficacious against 6 of the 13 isolates tested. CONCLUSIONS In contrast to tazobactam, IID572 was able to rescue piperacillin efficacy in murine thigh infection models established with β-lactamase-producing strains of Enterobacteriaceae and S. aureus, including those expressing ESBLs or serine carbapenemases.

Abstract
Abstract
Introduction
Prior studies have shown a morning circadian preference for African Americans compared to Non-Hispanic whites, but prior research has shown that self-reported sleep timing is delayed in African Americans compared to whites. No prior studies have evaluated this difference in sleep timing using objective measures of habitual sleep such as actigraphy.
Methods
We analyzed the sleep data from the Multi-Ethnicity Study of Atherosclerosis (MESA), a multi-site community-based cohort with both self-reported and actigraphic measures of habitual sleep variables. Self-reported sleep timing, chronotype as measured by the modified Horne-Ostberg Morningness-Eveningness Questionnaire (MEQ) and actigraphic sleep timing were examined using logistic regression and independent t-tests.
Results
1,430 participants had self-reported sleep data, and 1,405 participants had complete actigraphy data as well. There was no self-reported difference in circadian preference between African Americans and whites (mean MEQ score 17.1 ± 3.6 vs. 17.0 ± 4.0). African Americans were 76% more likely to report a bedtime after midnight on weekdays (odds ratio [OR] 1.8, 95% confidence interval [CI] 1.4, 2.3, p<0.001), and 50% more likely on weekends (OR 1.5, 95% CI 1.2, 1.9, p=0.001) as compared to whites. Actigraphic data showed similar results. African Americans were 80% more likely to have actigraphic sleep onset after midnight on weekdays (OR 1.8, 95% CI 1.4, 2.2) and 137% more likely (OR 2.4,95% CI 1.9, 3.0, p<0.001) on weekends as compared to whites. Actigraphic mid-sleep time was delayed 42 (95% CI 20, 64, p<0.001) minutes on weekdays and 24 (95% CI 6,42, p=0.01) minutes on weekends in African Americans compared to whites.
Conclusion
African Americans had delayed sleep timing compared to whites even though no significant racial differences in chronotype were present. Delayed sleep timing in African Americans may be related to factors other than self-reported circadian preference.

Abstract
Aims:Dual diagnosis of schizophrenic disorders and drug abuse/dependence are increasing due to more frequent use of cannabis and cocaine. It is important to differentiate between primary schizophrenia with associate drug abuse/dependence and drug-induced psychosis. The objective is to detect neuropsychological differences between drug users and non-users in schizophrenia patients, which could be used as diagnostic tools.Method:We conduct one case-control study on 12 schizophrenia out-patients (10 male) with vital history of drug abuse/dependence (mainly cannabis and cocaine) and one control group of 18 schizophrenia out-patients (12 male) who never used illegal drugs (global age mean: 32.8 years; SD:7.2). It was applied one neuropsychological battery sensitive to the neuropsychological deficit frequent in schizophrenia: WAIS-III, BADS, WCST, Colour Trails, Trail Making A and B, BVRT, California Verbal Learning Test (spanish version: TAVEC). Variables was summarized determining Z values and principal components. It was constructed one Logistic Regression Model to determinate the better predicting model of drug use state.Results:The resultant model included two predictors: WAIS Perceptive Organization Index and Trails Component. The prediction formula for Ln Odd Ratio of drug abuse/dependence group is: -13.83 + 1.09 (Trails Z score) + 0.16 (WAIS Perceptive Organization Index). It explains for 63% of the variance (p = 0.001). The ROC curve for using in diagnose was constructed.Conclusion:Neuropsychological diagnosis can contribute to the differential diagnosis of schizophrenia in dual pathology. The better functioning in visual-spatial tasks increases the probability of psychosis related with drugs use.

Abstract
Objectives The neutropenic murine thigh infection model and a dose-fractionation approach were used to determine the pharmacokinetic/pharmacodynamic (PK/PD) relationship of LYS228, a novel monobactam antibiotic with activity against Enterobacteriaceae including carbapenem-resistant strains. Methods Mice (n = 4 per group) were inoculated with Enterobacteriaceae strains via intramuscular injection. Two hours post-bacterial inoculation, treatment with LYS228 was initiated. Animals were euthanized with CO2 24 h after the start of therapy and bacterial counts (log10 cfu) per thigh were determined. PK parameters were calculated using free (f) plasma drug levels. Results Following a dose-fractionation study, non-linear regression analysis determined that the predominant PK/PD parameter associated with antibacterial efficacy of LYS228 was the percentage of the dosing interval that free drug concentrations remained above the MIC (%fT>MIC). In a dose-dependent manner, LYS228 reduced the thigh bacterial burden in models established with Enterobacteriaceae producing β-lactamase enzymes of all classes (e.g. ESBLs, NDM-1, KPC, CMY-2 and OXA-48). The range of the calculated static dose was 86-649 mg/kg/day for the isolates tested, and the magnitude of the driver of efficacy was 37-83 %fT>MIC. %fT>MIC was confirmed as the parameter predominantly driving efficacy as evidenced by a strong coefficient of determination (r2 = 0.68). Neutrophils had minimal impact on the effect of LYS228 in the murine thigh infection model. Conclusions LYS228 is efficacious in murine thigh infection models using β-lactamase-producing strains of Enterobacteriaceae, including those expressing metallo-β-lactamases, ESBLs and serine carbapenemases, with the PK/PD driver of efficacy identified as %T>MIC.

Abstract
A dry-film coliform count plate that is inoculated with 5 mL sample was compared with the Violet Red Bile Agar plate method in a collaborative study by 18 laboratories. Products analyzed were 2% milk, chocolate milk, cream, vanilla ice cream, cottage cheese, and cheese. Collaborators tested blind duplicate uninoculated samples and samples inoculated at low, medium, and high level. Significantly (P< 0.05) higher numbers of coliforms were recovered by the dry-film method from 2% milk samples at the 3 inoculum levels, the chocolate milk at the low- and high-inoculum levels, and the cream at the high-inoculum level. Significantly higher counts were obtained by the agar method for cottage cheese samples at the low-inoculum level. The repeatability standard deviation for the dry-film method was significantly higher for the high-inoculum level chocolate milk sample and the medium-inoculum level cottage cheese. The same statistic was significantly higher for the agar method at all 3 inoculum levels in the 2% milk and the medium-inoculum level cream. The high-sensitivity dry rehydratable film method for enumeration of coliforms in dairy products has been adopted first action by AOAC INTERNATIONAL.

Abstract
Aging is the major risk factor for the development of chronic diseases. After decades of research focused on extending lifespan, current efforts seek primarily to promote healthy aging. Recent advances suggest that biological processes linked to aging are more reliable than chronological age to account for an individual’s functional status, i.e. frail or robust. It is becoming increasingly apparent that biological aging may be detectable as a progressive loss of resilience much earlier than the appearance of clinical signs of frailty. In this context, the INSPIRE program was built to identify the mechanisms of accelerated aging and the early biological signs predicting frailty and pathological aging. To address this issue, we designed a cohort of outbred Swiss mice (1576 male and female mice) in which we will continuously monitor spontaneous and voluntary physical activity from 6 to 24 months of age under either normal or high fat/high sucrose diet. At different age points (6, 12, 18, 24 months), multiorgan functional phenotyping will be carried out to identify early signs of organ dysfunction and generate a large biological fluids/feces/organs biobank (100,000 samples). A comprehensive correlation between functional and biological phenotypes will be assessed to determine: 1) the early signs of biological aging and their relationship with chronological age; 2) the role of dietary and exercise interventions on accelerating or decelerating the rate of biological aging; and 3) novel targets for the promotion of healthy aging. All the functional and omics data, as well as the biobank generated in the framework of the INSPIRE cohort will be available to the aging scientific community. The present article describes the scientific background and the strategies employed for the design of the INSPIRE Mouse cohort.

Abstract
IntroductionThere is limited evidence favoring the use of the sentinel lymph node technique in ovarian cancer, and no standardized approach has been studied. The objective of the present pilot study is to determine the feasibility of the sentinel lymph node technique by applying a clinical algorithm.MethodsPatients with confirmed ovarian cancer were included. 99mTc and indocyanine green were injected into the ovarian and infundubulo-pelvic ligament stump. A gamma probe and near-infrared fluorescence imaging were used for sentinel lymph node detection.ResultsThe sentinel lymph node technique was performed in ten patients with a detection rate in the pelvic and/or para-aortic region of 100%. The tracer distribution rates of sentinel lymph nodes in the pelvic and para-aortic regions were 87.5% and 70%, respectively.ConclusionThe detection of sentinel lymph nodes in early-stage ovarian cancer appears to be achievable. Based on these results, a clinical trial entitled SENTOV (SENtinel lymph node Technique in OVarian cancer) will be performed.

Abstract
Wavelets are designed to have compact support in both time and frequency, giving them the ability to represent a signal in the two-dimensional time-frequency plane. The Gaussian, the Mexican hat and the Morlet wavelets are crude wavelets that can be used only in continuous decomposition. The Morlet wavelet is complex-valued and suitable for feature extraction using the continuous wavelet transform. Continuous wavelets are favoured when high temporal and spectral resolution is required at all scales. In this paper, considering the properties from the Morlet wavelet and based on the structure of a recurrent high-order neural network model, a novel wavelet neural network structure, here called a recurrent Morlet wavelet neural network, is proposed in order to achieve a better identification of the behaviour of dynamic systems. The effectiveness of our proposal is explored through the design of a decentralized neural backstepping control scheme for a quadrotor unmanned aerial vehicle. The performance of the overall neural identification and control scheme is verified via simulation and real-time results.This article is part of the theme issue 'Redundancy rules: the continuous wavelet transform comes of age'.

Abstract
SummaryVascular prostacyclin (PGI2) production is different in the arteries and veins of the dog. Experiments were performed to determine whether chronic grafting of the femoral vein into the arterial circulation would alter the normal PGI2 and thromboxane (TxA2) synthesis of the “arterialized” veins. Spontaneous and arachidonic acid (AA) stimulated PGI2 and TxA2 production (measured by radioimmunoassay of 6-keto PGF1α and TxB2 respectively) were analysed in full thickness punch biopsies of the middle part of the grafts after 3 and 16 months and compared with unoperated veins and arteries. PGI2 production was significantly higher in arteries than in veins but no significant difference in TxB2 production was found. Middle “arterialized” venous graft produced significantly lower amounts of PGI2 and higher amounts of TxB2 than unoperated vessels. PGI2 production was more reduced in the distal than in the middle or the proximal parts of the venous grafts especially when stimulated with AA. These findings do not support the concept that the venous graft was biochemically adapted or “arterialized” in terms of PGI2 production when implanted for 3 months or longer. Rather the markedly decreased PGI2/TxB2 ratio in the middle of the graft may be a contributory cause of thrombogenicity and may be implicated in the pathogenesis of neointimal hyperplasia.

Abstract
VP2/VP6 virus like particles (VLPs) are very effective in inducing protection against the rotavirus infection in animal models. Individually, VP6 can also induce protection. However, there is no information about the immunogenicity of VP2. The aim of this work was to evaluate the efficacy of DNA vaccines codifying for VP2 or VP6, alone or combined, to induce protection against the rotavirus infection. Murine rotavirus VP2 and VP6 genes were cloned into the pcDNA3 vector. Adult BALB/c mice were inoculated three times by intramuscular (i.m.) injections with 100 or 200µg of pcDNA3-VP2 or pcDNA3-VP6 alone or co-administered with 100µg of pcDNA3-VP2/100µg of pcDNA3-VP6. Two weeks after the last inoculation, mice were challenged with the wild type murine rotavirus strain epizootic diarrhea of infant mice (EDIMwt). We found that both plasmids, pcDNA3-VP2 and pcDNA3-VP6, were able to induce rotavirus-specific serum antibodies, but not intestinal rotavirus-specific IgA; only 200µg of pcDNA3-VP6 induced 35% protection against the infection. A similar level of protection was found when mice were co-administered with 100µg of pcDNA3-VP2/100µg of pcDNA3-VP6 (1:1 ratio). However, the best protection (up to 58%) occurred when mice were inoculated with 10µg of pcDNA3-VP2/100µg of pcDNA3-VP6 (1:10 ratio). These results indicate that the DNA plasmid expressing VP6 is a better vaccine candidate that the one expressing VP2. However, when co-expressed, VP2 potentiates the immunogenicity and protective efficacy of VP6.

Abstract
Designing systems that merge the advantages of heterogeneous catalysis, enzymology, and molecular catalysis represents the next major goal for sustainable chemistry. Cross-linked enzyme crystals display most of these essential assets (well-designed mesoporous support, protein selectivity, and molecular recognition of substrates). Nevertheless, a lack of reaction diversity, particularly in the field of oxidation, remains a constraint for their increased use in the field. Here, thanks to the design of cross-linked artificial nonheme iron oxygenase crystals, we filled this gap by developing biobased heterogeneous catalysts capable of oxidizing carbon-carbon double bonds. First, reductive O2 activation induces selective oxidative cleavage, revealing the indestructible character of the solid catalyst (at least 30 000 turnover numbers without any loss of activity). Second, the use of 2-electron oxidants allows selective and high-efficiency hydroxychlorination with thousands of turnover numbers. This new technology by far outperforms catalysis using the inorganic complexes alone, or even the artificial enzymes in solution. The combination of easy catalyst synthesis, the improvement of "omic" technologies, and automation of protein crystallization makes this strategy a real opportunity for the future of (bio)catalysis.

Abstract
Hemorrhagic cystitis is generally a benign self-limited disorder, however there are some severe cases which are associated to a significant blood loss. The etiology may be either bacterial, viral or chemical in origin; though the cause is not identified in most of the cases. Immunocompromised patients or patients who have undergone chemotherapy or radiation constitute the highest risk group. There are only a few articles about hemorrhagic cystitis in pregnancy, frequently associated with preterm labor. We describe, for the first time in literature, one patient with a clinical status of hematuria in two consequent pregnancies, without any identified cause and a medical history negative for recurrent or hemorrhagic cystitis and we report an overview of literature concerning this topic.

Abstract
<p>This study aimed to evaluate the effect of feeding dried foliage (leaves and petioles) of <em>Acacia saligna</em>, <em>Leucaena leucocephala</em> or <em>Moringa oleifera</em> on the performance, digestibility, N utilisation, caecal fermentation and microbial profiles in New Zealand White (NZW) rabbits. One hundred weaned male NZW rabbits weighing 819.2±16.6 g and aged 35±1 d were randomly allocated into 4 groups of 25 rabbits each. Rabbits were fed on pelleted diets containing 70% concentrate mixture and 30% Egyptian berseem (<em>Trifolium alexandrinum</em>) hay (Control diet) or one of the other 3 experimental diets, where 50% of berseem hay was replaced with <em>A. saligna</em> (AS), <em>L. leucocephala</em> (LL) or <em>M. oleifera</em> (MO). Compared to Control diet, decreases in dry matter (DM; <em>P</em>=0.004), organic matter (<em>P</em>=0.028), crude protein (CP; <em>P</em>=0.001), neutral detergent fibre (<em>P</em>=0.033) and acid detergent fibre (<em>P</em>=0.011) digestibility were observed with the AS diet. However, DM and CP digestibility were increased by 3% with the MO diet, and N utilisation was decreased (<em>P</em><0.05) with AS. Rabbits fed AS and LL diets showed decreased (<em>P</em>=0.001) average daily gain by 39 and 7%, respectively vs. Control. Feed conversion was similar in Control and MO rabbits, whereas rabbits fed AS diet ate up to 45% more feed (<em>P</em>=0.002) than Control rabbits to gain one kg of body weight. Caecal ammonia-N was increased (<em>P</em>=0.002) with LL, while acetic acid was decreased (<em>P</em>=0.001) with AS diet vs. other treatments. Caecal <em>E. coli</em> and <em>Lactobacillus</em> spp. bacteria counts were decreased with MO by about 44 and 51%, respectively, vs. Control. In conclusion, under the study conditions, tree foliage from <em>M. oleifera</em> and <em>L. leucocephala</em> are suitable fibrous ingredients to be included up to 150 g/kg in the diets of growing rabbits, and can safely replace 50% of berseem hay in diets of NZW rabbits without any adverse effect on their growth performance. Foliage from <em>M. oleifera </em>had a better potential as a feed for rabbits than that from <em>L. leucocephala</em>. Although foliage from <em>A. saliga </em>may be also used at 150 g/kg in the diets of growing rabbits, this level of inclusion may result in reduced feed digestibility and growth performance.</p>

Abstract
Feralisation occurs when a domestic population recolonizes the wild, escaping its previous restricted environment, and has been considered as the reverse of domestication. We have previously shown that Kauai Island's feral chickens are a highly variable and admixed population. Here we map selective sweeps in feral Kauai chickens using whole-genome sequencing. The detected sweeps were mostly unique to feralisation and distinct to those selected for during domestication. To ascribe potential phenotypic functions to these genes we utilize a laboratory-controlled equivalent to the Kauai population-an advanced intercross between Red Junglefowl and domestic layer birds that has been used previously for both QTL and expression QTL studies. Certain sweep genes exhibit significant correlations with comb mass, maternal brooding behaviour and fecundity. Our analyses indicate that adaptations to feral and domestic environments involve different genomic regions and feral chickens show some evidence of adaptation at genes associated with sexual selection and reproduction.

Abstract
Purpose/objectives The aim of this study is to analyze the results of exclusive interstitial brachytherapy (IBT) as a conservative approach in the treatment of penile cancer confined to the glans or the shaft with long-term follow-up in a single institution. Materials/methods Between July 1992 and November 2013, 73 consecutive patients with non-metastatic invasive penile cancer were treated by Low dose rate (LDR) IBT in our institution. The localization of the primary lesion was glands in 67 patients (91.8 %) and shaft in 6 patients (8.2 %). All 73 patients presented with squamous cell carcinoma with grades of differentiation as follows: 34 patients with grade 1 (44.7 %), 9 patients with grade 2 (11.8 %), 9 patients with grade 3 (11.8 %) and 21 patients unknown (28.8 %). Six patients (7.8 %) presented with in situ carcinoma, 55 patients (75,3 %) presented with T1, 11 patients (15 %) presented with T2, and one patient (1.3 %) presented with Tx. Inguinal nodal dissection was performed in 29 patients (38.2 %); 13 patients (17.8 %) presented with histologically confirmed positive ganglion. After circumcision, IBT was performed using a hypodermic needle. The median dose delivered was 60 Gy (range, 40 to 70 Gy). The median activity of the iridium-192 wire was 1.12 mCi/cm, and the median reference isodose rate was 0.4 Gy/h (range, 0.2–1.2). Patients with histological inguinal metastases received external beam radiotherapy to the selected inguinal affected area with a median dose of 45 Gy (30–55 Gy). Results The median follow-up time was 51.8 months (range 34.4 to 68.7). The 5-year overall survival was 82.0 %, with eight deaths from cancer and five non-cancer-related deaths. Disease-specific survival was 91.4 %, relapse-free survival was 64.4 %, and local relapse-free survival as 74 %. Total or partial penile preservation was 87.9 % at 5-years. Complications rates at 5 years were 6.6 % urethral stenosis (five patients), two patients (2.6 %) with pain related to sexual intercourse and four patients (5.3 %) with dysuria grade 2. Five patients (6.8 %) required penile amputation for necrosis. Conclusions IBT provides good local control with organ preservation, excellent tolerance and low complication rates in early-stage penile cancers.
