Abstract
Spontaneous subcapsular and perirenal hemorrhage, known as Wunderlich syndrome (WS), is a rare clinical manifestation of polyarteritis nodosa (PAN). We report a case of a 48-year-old male with a history of recurrent episodes of leg muscle tenderness and dysesthesia, bilateral flank pain, painful nodular skin lesions in the lower limbs, weight loss, and difficult-to-control arterial hypertension. The abdominopelvic computed tomography angiography showed a large left perirenal hematoma, leading to the patient's admission to the intensive care unit. After the exclusion of infectious or neoplastic foci, the patient was diagnosed with PAN and started intravenous methylprednisolone pulses with a good response. Since WS is a rare initial clinical manifestation of PAN, an early diagnosis and aggressive treatment will significantly improve clinical outcomes.

Abstract
Infection by retroviruses as HIV-1 requires the stable integration of their genome into the host cells. This process needs the formation of integrase (IN)-viral DNA complexes, called intasomes, and their interaction with the target DNA wrapped around nucleosomes within cell chromatin. To provide new tools to analyze this association and select drugs, we applied the AlphaLISA technology to the complex formed between the prototype foamy virus (PFV) intasome and nucleosome reconstituted on 601 Widom sequence. This system allowed us to monitor the association between both partners and select small molecules that could modulate the intasome/nucleosome association. Using this approach, drugs acting either on the DNA topology within the nucleosome or on the IN/histone tail interactions have been selected. Within these compounds, doxorubicin and histone binders calixarenes were characterized using biochemical, in silico molecular simulations and cellular approaches. These drugs were shown to inhibit both PFV and HIV-1 integration in vitro. Treatment of HIV-1-infected PBMCs with the selected molecules induces a decrease in viral infectivity and blocks the integration process. Thus, in addition to providing new information about intasome-nucleosome interaction determinants, our work also paves the way for further unedited antiviral strategies that target the final step of intasome/chromatin anchoring. IMPORTANCE In this work, we report the first monitoring of retroviral intasome/nucleosome interaction by AlphaLISA. This is the first description of the AlphaLISA application for large nucleoprotein complexes (>200 kDa) proving that this technology is suitable for molecular characterization and bimolecular inhibitor screening assays using such large complexes. Using this system, we have identified new drugs disrupting or preventing the intasome/nucleosome complex and inhibiting HIV-1 integration both in vitro and in infected cells. This first monitoring of the retroviral/intasome complex should allow the development of multiple applications including the analyses of the influence of cellular partners, the study of additional retroviral intasomes, and the determination of specific interfaces. Our work also provides the technical bases for the screening of larger libraries of drugs targeting specifically these functional nucleoprotein complexes, or additional nucleosome-partner complexes, as well as for their characterization.

Abstract
Introduction L’infection par le SARS-CoV-2 peut entraîner une inflammation sévère et il a été suggéré d’induire des poussées de rhumatisme psoriasique (RP). Cependant, l’impact sur l’activité de la maladie et la réponse aux DMARD biologiques modificateurs de la maladie (bDMARD) reste inconnu. Patients et méthodes Nous avons réalisé une analyse rétrospective incluant tous les patients atteints de RP, répondant aux critères CASPAR et sous biothérapie, suivis dans le service de rhumatologie d’un CHU universitaire tertiaire. Les données démographiques et cliniques, y compris la survenue d’une infection par le SARS-CoV-2, ont été collectées à partir de notre base de données nationale (reuma.pt). L’activité de la maladie (CDAI, SDAI, DAS28 4v, BASDAI, ASDAS) et les réponses aux bDMARD (réponses EULAR, ASDAS, ASAS, ACR et PsARC) ont été évaluées avant et après l’infection par le SARS-Cov-2. Résultats Au total, 102 patients atteints de RP ont été inclus. Cinquante-deux étaient des femmes (51 %). L’âge moyen était de 53 ± 11,09 ans et la durée médiane de la maladie était de 15 ans [min 2, max 47]. Au total, 54 (53 %) patients avaient une atteinte axiale prédominante, 26 (26 %) périphérique et 36 (37 %) enthésopathique. Le bDMARD le plus utilisé était l’étanercept (n = 28, 27,5 %) suivi de l’adalimumab (n = 22, 21,6 %) et du sécukinumab (n = 18, 17,6 %). La prévalence de l’infection par le SARS-CoV-2 était de 15,7 % (n = 16). Soixante-trois pour cent ont reçu le vaccin BNT162b2 (Pfizer/BioNtech), 31 % ont reçu l’ARNm-1273 (Moderna), 13 % ont reçu l’AZD1222 (AstraZeneca) et 13 % ont reçu l’AD26.COV2.S (Janssen/Johnson & Johnson). Soixante-trois pour cent étaient infectés avant toute vaccination, 13 % après la première dose et 25 % après la seconde. Les symptômes les plus fréquents étaient l’anosmie (65 %), la dysgueusie (56 %) et la toux (56 %). Tous les patients se sont complètement remis de l’infection, sans nécessiter d’hospitalisation. Quel que soit le score utilisé, la différence entre l’activité moyenne de la maladie après l’infection par le SARS-CoV-2 et celle au départ n’a pas atteint la signification statistique. Au départ et après l’infection, les paramètres moyens de l’activité de la maladie étaient respectivement : CDAI 8,6 ± 5,7 vs 8,6 ± 5,7, p = 0,997 ; SDAI 9,3 ± 6,6 contre 9,2 ± 6,1, p = 0,928 ; DAS 28 4v 2,9 ± 1,2 contre 2,9 ± 1,2, p = 0,818 ; BASDAI 3,6 ± 2,6 contre 3,2 ± 2,7, p = 0,506 ; ASDAS 2,2 ± 1,2 contre 2,2 ± 1, p = 0,721. Le nombre de patients ne répondant pas aux bDMARD (selon EULAR, ASDAS, ASAS, ACR et PsARC) avant l’infection n’était pas différent de celui post-infection. Conclusion Notre étude suggère que l’infection par le SARS-CoV-2 n’a aucun impact négatif sur l’activité de la maladie PSA et les réponses bDMARD. Cependant, d’autres études sont encore nécessaires pour mieux comprendre les effets à long terme de l’infection par le SARS-CoV-2.

Abstract
The Brazilian Amazon has high rates of snakebite envenomings (SBEs), with ∼90% caused by Bothrops atrox. Envenomings by this species can trigger local and systemic effects, such as acute kidney injury (AKI). Our aim was to identify predictors of AKI in Bothrops SBEs in patients from Manaus, Western Brazilian Amazon. A total of 127 patients were enrolled, with a predominance of men between 16 and 45 years old from rural areas. Of the 127 patients, 38.6% developed AKI, with 61.2% presenting stage I, 34.7% presenting stage II and 4.1% presenting stage III severity. The age groups 0-10 years and ≥60 years presented a significantly higher frequency of AKI compared to the 11-40 years group. Moderate/severe edema in the affeccted limb was significantly associated with lower risk of AKI [p = 0.01; OR = 0.11 (95%CI 0.02-0.53)]. Nausea [p = 0.01; OR = 54.44 (95%CI = 3.26-909.27)] and high blood urea levels [p = 0.01; OR = 5.38 (95%CI = 2.12-13.66)] were risk factors for AKI. There was a significant positive correlation between circulating venom levels and the highest creatinine serum values during the hospital stay (p = 0.03) and with the difference between the maximum creatinine levels and the creatinine levels on admission (p = 0.02). A positive correlation between serum venom concentrations and creatinine levels suggests a direct or indirect dose-dependent participation of the venom toxins in the pathogenesis of AKI.

Abstract
Background The existing digital healthcare solutions demand a service development approach that assesses needs, experience, and outcomes, to develop high-value digital healthcare services. The objective of this study was to develop a digital transformation of the patients’ follow-up service after cardiac surgery, based on a remote patient monitoring service that would respond to the real context challenges. Methods The study followed the Design Science Research methodology framework and incorporated concepts from the Lean startup method to start designing a minimal viable product (MVP) from the available resources. The service was implemented in a pilot study with 29 patients in 4 iterative develop-test-learn cycles, with the engagement of developers, researchers, clinical teams, and patients. Results Patients reported outcomes daily for 30 days after surgery through Internet-of-Things (IoT) devices and a mobile app. The service’s evaluation considered experience, feasibility, and effectiveness. It generated high satisfaction and high adherence among users, fewer readmissions, with an average of 7 ± 4.5 clinical actions per patient, primarily due to abnormal systolic blood pressure or wound-related issues. Conclusions We propose a 6-step methodology to design and validate a high-value digital health care service based on collaborative learning, real-time development, iterative testing, and value assessment.

Abstract
Introdução: O Brasil, assim como outros países, vem alterando seu perfil demográfico elevando o número de pessoas idosas, o que repercute em mudanças não só para sociedade, mas também para saúde pública. Este grupo de pacientes é mais vulnerável devido à fisiologia inerente ao envelhecimento, logo se tornam mais propensos ao uso de medicamentos que podem causar outros problemas de saúde. Essa probabilidade de risco é uma preocupação atual e levou a criação de métodos que norteiam os prescritores para adequarem suas terapêuticas neste grupo de pacientes. Um destes métodos é o critério de Beers, que é atualizado periodicamente trazendo uma lista de medicamentos potencialmente inapropriados (MPIs) para idosos. Objetivo: Avaliar a prescrição de pacientes idosos internados no Hospital Universitário da Universidade Federal de Juiz de Fora (HU-UFJF/Ebserh) quanto à prevalência do uso de MPI e polifarmácia, no período de julho a agosto de 2019. Material e Métodos: Estudo observacional descritivo e retrospectivo, cujos dados foram coletados de prontuários pacientes idosos com idade igual ou superior a 65 anos para obtenção dos resultados que foram avaliados estatisticamente. Resultados: Foram avaliados 187 prontuários, e observada prevalência de 80,2% da prescrição de MPIs, sendo os mais prevalentes omeprazol e benzodiazepínicos. A maioria dos pacientes tiveram polifarmácia (95,7%). Conclusão: Os resultados convergem com base no critério de Beers, para necessidade de adequar a terapia de pacientes idosos. É necessário também avaliar os benefícios e alternativas quanto aos MPIs mais prevalentes, além de realizar estudos observacionais sobre possíveis efeitos adversos que possam ser consequência do uso desses medicamentos, com objetivo de aperfeiçoar a terapia farmacológica e aprimorar a farmacoeconomia, melhorando assim a qualidade de vida dos pacientes idosos.

Abstract
Understanding the genetic basis of environmental adaptation in natural populations is a central goal in evolutionary biology. The conditions at high elevation, particularly the low oxygen available in the ambient air, impose a significant and chronic environmental challenge to metabolically active animals with lowland ancestry. To understand the process of adaptation to these novel conditions and to assess the repeatability of evolution over short timescales, we examined the signature of selection from complete exome sequences of house mice (Mus musculus domesticus) sampled across two elevational transects in the Andes of South America. Using phylogenetic analysis, we show that house mice colonized high elevations independently in Ecuador and Bolivia. Overall, we found distinct responses to selection in each transect and largely nonoverlapping sets of candidate genes, consistent with the complex nature of traits that underlie adaptation to low oxygen availability (hypoxia) in other species. Nonetheless, we also identified a small subset of the genome that appears to be under parallel selection at the gene and SNP levels. In particular, three genes (Col22a1, Fgf14, and srGAP1) bore strong signatures of selection in both transects. Finally, we observed several patterns that were common to both transects, including an excess of derived alleles at high elevation, and a number of hypoxia-associated genes exhibiting a threshold effect, with a large allele frequency change only at the highest elevations. This threshold effect suggests that selection pressures may increase disproportionately at high elevations in mammals, consistent with observations of some high-elevation diseases in humans.

Abstract
In this study, the interaction between benzothiazole (BTA, concentration of a drug required for 50% inhibition in vitro (IC50) = 0.77 mM) and benzimidazole (BIA, IC50 = 2.14 mM) with urease was quantitatively assessed, using UV-Vis, molecular fluorescence, and circular dichroism. The results showed that both compounds interact with urease by a static fluorescence quenching mechanism with a non-fluorescent complex formation. The main forces responsible for stabilizing the supramolecular complex between BTA and urease were hydrophobic while, for BIA, van der Waals interactions and hydrogen bonds were the main ones. Urease conformation changes due to the interaction process were analyzed by circular dichroism and synchronous fluorescence. Besides, a competitive assay with substrate and inhibitors was used to evaluate the preferential urease site of interaction with BTA and BIA. Our experimental and theoretical studies supported that both, BTA and BIA, are mixed-inhibitors of ureases with a slight preference to the active site of such enzymes. Finally, both BTA and BIA showed to possess anti-H. pylori (one reference strain and six clinical isolates) activity, presenting minimal inhibitory concentration (MIC) values ranging from 38-150 and 20-164 μM, respectively. The urease inhibitors omeprazole and hydroxyurea showed MIC values in the range of 46-185 μM and 1683-> 3366 μM, respectively.

Abstract
The current COVID-19 pandemic has already claimed more than 3.7 million victims and it will cause more deaths in the coming months. Tools that track the number and locations of cases are critical for surveillance and help in making policy decisions for controlling the outbreak. However, the current surveillance web-based dashboards run on proprietary platforms, which are often expensive and require specific computational knowledge. We developed a user-friendly web tool, named OUTBREAK, that facilitates epidemic surveillance by showing in an animated graph the timeline and geolocations of cases of an outbreak. It permits even non-specialist users to input data most conveniently and track outbreaks in real-time. We applied our tool to visualize the SARS 2003, MERS, and COVID19 epidemics, and provided them as examples on the website. Through the zoom feature, it is also possible to visualize cases at city and even neighborhood levels. We made the tool freely available at https://outbreak.sysbio.tools/ . OUTBREAK has the potential to guide and help health authorities to intervene and minimize the effects of outbreaks.

Abstract
The Water Framework Directive (WFD) was adopted in 2000 and is a common framework for water policy, management and protection in Europe. The WFD assesses specific parameters; however, it ignores indicators of ecosystem functioning and sub-individual performance. Reservoirs are strongly influenced by anthropogenic activities that promote their imbalance. Bioassays and biomarkers are useful tools to link the chemical, ecological and toxicological assessments in water quality assessments. These approaches can be complementary to WFD methodologies, allowing the detection of impacts on the ecosystem. This study evaluated if the biochemical parameters can improve the sensitivity of the biomonitoring strategy using bioassays with the standard species Daphnia magna, in the assessment of the ecological quality of water reservoirs. To this end, water samples of Portuguese reservoirs were analysed in three sampling periods (Autumn 2018 and Spring, Autumn 2019). In parallel, a physicochemical characterization of waters was performed. D. magna feeding rate assays were performed for 24 h. After exposure, metabolism, oxidative stress and lipid peroxidation biomarkers were evaluated. Feeding rate assays showed sensitivity to different reservoirs. Biomarkers showed a higher sensitivity and can therefore improve the sensitivity of the biomonitoring strategy using bioassays. Bioassays and biomarkers approach allowed to highlight potential sources of stress, more related to the quality of the seston than to chemical contamination. This work highlights the complementarity between bioassays and biomarkers to identify ecotoxicological effects of surface waters, and can be extremely useful, especially in cases where the biotic indices are difficult to establish, such as reservoirs.

Abstract
BACKGROUND The progression and severity of COVID-19 vary significantly in the population. While the hallmarks of SARS-CoV-2 and severe COVID-19 within routine laboratory parameters are emerging, the impact of sex and age on these profiles is still unknown. METHODS A multidimensional analysis was performed involving millions of records of laboratory parameters and diagnostic tests for 178 887 individuals from Brazil, of whom 33 266 tested positive for SARS-CoV-2. Analyzed data included those relating to complete blood cell count, electrolytes, metabolites, arterial blood gases, enzymes, hormones, cancer biomarkers, and others. FINDINGS COVID-19 induced similar alterations in laboratory parameters in males and females. CRP and ferritin were increased, especially in older men with COVID-19, whereas abnormal liver function tests were common across several age groups, except for young women. Low peripheral blood basophils and eosinophils were more common in the elderly with COVID-19. Both male and female COVID-19 patients admitted to intensive care units displayed alterations in the coagulation system, and higher values for neutrophils, CRP, and lactate dehydrogenase. CONCLUSIONS Our study uncovered the laboratory profiles of a large cohort of COVID-19 patients, which formed the basis of discrepancies influenced by aging and biological sex. These profiles directly linked COVID-19 disease presentation to an intricate interplay between sex, age, and immune activation.

Abstract
AIMS Little is known about the prognosis of patients with massive pulmonary embolism (PE) and its risk of recurrent venous thromboembolism (VTE) compared with non-massive PE, which may inform clinical decisions. Our aim was to compare the risk of recurrent VTE, bleeding, and mortality after massive and non-massive PE during anticoagulation and after its discontinuation. METHODS AND RESULTS We included all participants in the RIETE registry who suffered a symptomatic, objectively confirmed segmental or more central PE. Massive PE was defined by a systolic hypotension at clinical presentation (<90 mm Hg). We compared the risks of recurrent VTE, major bleeding, and mortality using time-to-event multivariable competing risk modeling. There were 3.5% of massive PE among 38 996 patients with PE. During the anticoagulation period, massive PE was associated with a greater risk of major bleeding (subhazard ratio [sHR] 1.72, 95% confidence interval [CI] 1.28-2.32), but not of recurrent VTE (sHR 1.15, 95% CI 0.75-1.74) than non-massive PE. An increased risk of mortality was only observed in the first month after PE. After discontinuation of anticoagulation, among 11 579 patients, massive PE and non-massive PE had similar risks of mortality, bleeding, and recurrent VTE (sHR 0.85, 95% CI 0.51-1.40), but with different case fatality of recurrent PE (11.1% versus 2.4%, P = .03) and possibly different risk of recurrent fatal PE (sHR 3.65, 95% CI 0.82-16.24). CONCLUSION In this large prospective registry, the baseline hemodynamic status of the incident PE did not influence the risk of recurrent VTE, during and after the anticoagulation periods, but was possibly associated with recurrent PE of greater severity.

Abstract
Operational tolerance (OT) is the phenomenon occurring in human renal and liver transplantation in which the body does not reject the organ after discontinuing immunosuppression for at least a year. We revisited the data generated by The Brazilian Multicenter Study on Operational Tolerance involving different conceptual fields - antigen-specific cytokine response, immune cell numbers and repertoire, signaling pathways, and epigenetics. We integrated our data to pave the way to systems biology thinking and harness debate on potential mechanisms in OT. We present original data on systems biology in OT, connecting potential mechanistic players. Using bioinformatics, we identified three dominant features that discriminate OT from its opposing clinical outcome, chronic rejection (CR). The OT-CR discriminative molecules were FOXP3, GATA3 and STAT6, each corresponding to a differential profile: (1) In FOXP3, OT presents preserved regulatory T cell (Treg) numbers but decreased numbers in CR; (2) in GATA3, increased expression is seen in OT; and (3) in STAT6, decreased monocyte activation is seen in OT. With these variables, we built molecular networks to identify interactions related to OT versus CR. Our first systems biology endeavor gave rise to novel potentially relevant interconnected players in OT mechanisms: FOXP3 connecting to interleukin-9 (IL-9) and IL-35 signaling, suggesting their immunoregulatory involvement in OT. Likewise, GATA3/FOXP3 interactions incrementing/stabilizing FOXP3 transcription suggest participation in keeping healthy FOXP3+ Tregs in OT. We envision that systems biology thinking will greatly contribute to advancing knowledge in human transplantation tolerance in an interactive perspective.

Abstract
Abstract
Introduction
Primary cardiac tumors are rare entities and 75% are benign. Angiosarcoma is the most common malignant primary cardiac tumor.
We report the case of cardiac angiosarcoma presenting with an atrial arrhythmia.
Clinical case
A 39-year-old female patient with no past medical history presented to the emergency department with heart palpitations and atypical chest pain.
Electrocardiogram on admission showed atrial flutter with a heart rate of 153 beats per minute.
Laboratory analysis were performed showing elevated D-dimer levels (2210 ug/L).
A thoracic CT scan was performed, which ruled out pulmonary embolism, but showed multiple pulmonary nodules and a right atrial (RA) mass measuring 48 mm that could correspond to a thrombus or neoplasia.
The patient was admitted in the Cardiology ICU of our hospital and was started on beta-blocker and amiodarone with conversion to sinus rhythm. Additional exams were performed:
- Transthoracic echocardiogram (TTE) revealed an heterogenous 32,6 x 17,7 mm mass in the lateral wall of the RA with an adherent mobile mass near the tricuspid valve with 28 mm diameter (possible adherent thrombus).
- Cardiac magnetic resonance imaging confirmed a RA tumor with invasion of the atrial free wall and compression of the superior vena cava.
Due to the unclear etiology of the RA mass, ultrasound-guided intracardiac biopsy was performed. Pathological examination revealed spindle cell proliferation, consistent with the diagnosis of angiosarcoma. Immunohistochemical staining was positive for Vimentin, CD34 and CD31, with 70% Ki67 expression.
Later on, the patient developed melena with significant drop of hemoglobin levels, requiring daily red blood cell transfusions and anticoagulation had to be stopped.
The patient was transferred to the Internal Medicine ward and thoracic-abdomen-pelvis staging computed tomography (CT) scan showed a significant increase in the number of pulmonary nodules, bilateral ovarian masses, 4 hepatic nodules and ileum metastization.
During hospitalization, the patient developed right leg deep venous thrombosis and thoracic CT scan revealed bilateral pulmonary embolism.
After improvement of the clinical status, palliative chemotherapy was started and the patient was discharged, maintaining regular outpatient follow-up in the Oncology Department for 1 month.
Cardiac angiosarcoma generally presents in a late stage of the disease with metastatic involvement. When surgical treatment is not possible, despite agressive chemotherapy, the prognosis remains poor.

Abstract
Cancers are complex tissues composed by genetically altered cancer cells and stromal elements such as inflammatory/immune cells, fibroblasts, endothelial cells and pericytes, neuronal cells, and a non-cellular component, the extracellular matrix. The complex network of interactions and crosstalk established between cancer cells and the supportig cellular and non-cellular components of the microenvironment are of extreme importance for tumor initiation and progression, strongly impacting the course and the outcome of the disease. Therefore, a better understanding of the tumorigenic processes implies the combined study of the cancer cell and the biologic, chemical and mechanic constituents of the tumor microenvironment, as their concerted action plays a major role in the carcinogenic pathway and is a key determinant of the efficacy of anti-cancer treatments. The use of animal models (e.g. Mouse, Zebrafish and Drosophila) to study cancer has greatly impacted our understanding of the processes governing initiation, progression and metastasis and allowed the discovery and pre-clinical validation of novel cancer treatments as it allows to recreate tumor development in a more pathophysiologic environment.

Abstract
The impact of climate change may be felt most keenly by tropical ectotherms. In these taxa, it is argued, thermal specialization means a given shift in temperature will have a larger effect on fitness. For species with limited dispersal ability, the impact of climate change depends on the capacity for their climate-relevant traits to shift. Such shifts can occur through genetic adaptation, various forms of plasticity, or a combination of these processes. Here we assess the extent and causes of shifts in 7 physiological traits in a tropical lizard, the rainforest sunskink (Lampropholis coggeri). Two populations were sampled that differ from each other in both climate and physiological traits. We compared trait values in each animal soon after field collection versus following acclimation to laboratory conditions. We also compared trait values between populations in: (i) recently field-collected animals; (ii) the same animals following laboratory acclimation; and (iii) the laboratory-reared offspring of these animals. Our results reveal high trait lability, driven primarily by acclimation and local adaptation. By contrast, developmental plasticity, resulting from incubation temperature, had little to no effect on most traits. These results suggest that, while specialized, tropical ectotherms may be capable of rapid shifts in climate-relevant traits.

Abstract
There is justified concern about the impact of global warming on the persistence of tropical ectotherms. There is also growing evidence for strong selection on climate-relevant physiological traits. Understanding the evolutionary potential of populations is especially important for low dispersal organisms in isolated populations, because these populations have little choice but to adapt. Despite this, direct estimates of heritability and genetic correlations for physiological traits in ectotherms-which will determine their evolutionary responses to selection-are sparse, especially for reptiles. Here we examine the heritabilities and genetic correlations for a set of four morphological and six climate-relevant physiological traits in an isolated population of an Australian rainforest lizard, Lampropholis coggeri. These traits show considerable variation across populations in this species, suggesting local adaptation. From laboratory crosses, we estimated very low to moderate heritability of temperature-related physiological traits (h2 < 0.31), but significant and higher heritability of desiccation resistance (h2~0.42). These values contrasted with uniformly higher heritabilities (h2 > 0.51) for morphological traits. At the phenotypic level, there were positive associations among the morphological traits and between thermal limits. Growth rate was positively correlated with thermal limits, but there was no indication that morphology and physiology were linked in any other way. We found some support for a specialist-generalist trade-off in the thermal performance curve, but otherwise there was no evidence for evolutionary constraints, suggesting broadly labile multivariate trait structure. Our results indicate little potential to respond to selection on thermal traits in this population and provide new insights into the capacity of tropical ectotherms to adapt in situ to rapid climate change.

Abstract
INTRODUCTION Panurethral stricture associated with lichen sclerosus is a therapeutic challenge. We present the analysis of our results using two urethroplasty techniques based on oral mucosa graft. MATERIAL AND METHOD Retrospective study in patients with long anterior urethral stricture (>8cm) associated with lichen sclerosus. Patients received urethroplasty with oral mucosa graft technique according Kulkarni (n=25) or two-step Johanson-Bracka urethroplasty (n=15). Demographics, operative time, complications (Clavien-Dindo), hospital stay, days with catheter, EAV postoperative pain, failure rate, need for retreatment and functional data including IPSS, QoL, Qmax, post void residual (PVR) are evaluated. RESULTS In all cases there was involvement of glandular and penile urethra, and in 75% of bulbar urethra. A single graft was used in 22.5%, two in 72.5% and three in 5%. Patients treated at a single step were younger (P=.007). Although the length of the stenosis was equivalent in both techniques (P=.96), relapse and complication rates were higher in two-step surgery (P=.05 and P=.03; respectively) and so was operative time (P<.0001) and overall stay (P=.0002). There were no differences in preoperative IPSS, QoL, Qmax or PVR, neither in postoperative values of IPSS or Qmax; but there was a difference in QoL (P=.006) and PVR (P=.03) favouring single-step urethroplasty. VAS pain on postoperative day 1 was also lower in Kulkarni urethroplasty than in the first step of Johanson-Bracka technique (P<.0001). CONCLUSIONS In patients with lichen sclerosus and long anterior urethral stricture Kulkarni urethroplasty provides more efficient and better patient reported outcomes than Johanson-Bracka urethroplasty. It also prevents cosmetic, sexual and voiding temporary deterioration inherent to 2-step surgery.

Abstract
Synaptosomes are isolated nerve terminals. They represent an extremely attractive in vitro model system to study synaptic physiology since they preserve morphological and functional characteristics of the synapse. As such they have been used to investigate synaptic dysfunctions associated with neuropathologies like Alzheimer's disease. In the present work two simple methodologies for isolating synaptosomal-enriched fractions were compared for the first time. The starting points of both protocols were rat cortical or hippocampal homogenized tissues that underwent several differential centrifugation steps followed by a final purification of synaptosomal-enriched fractions using either a Percoll gradient or a Sucrose gradient. Comparison of the fractions obtained was carried out, using both biochemical and electron microscopy approaches. In the biochemical analysis the protein levels of pre-synaptic, post-synaptic, nuclear and mitochondrial markers were evaluated. Additional characterization of the synaptosomal-enriched fractions was performed using transmission electron microscopy. In summary, the results indicate that under the conditions tested the Sucrose based protocol is more efficient for the isolation of synaptosomal-enriched fractions from both neuronal tissues, being particularly efficient for hippocampus that is a less abundant brain tissue. Further, the sucrose protocol apparently results in a higher yield of viable synaptosomes suitable for further assays, including structural and functional studies of synapses; making this an attractive procedure to study processes associated with neuropathologies.

Abstract
The Kondo effect is the many-body screening of a local spin by a cloud of electrons at very low temperature. It has been proposed as an explanation of the zero-bias anomaly in quantum point contacts where interactions drive a spontaneous charge localization. However, the Kondo origin of this anomaly remains under debate, and additional experimental evidence is necessary. Here we report on the first phase-sensitive measurement of the zero-bias anomaly in quantum point contacts using a scanning gate microscope to create an electronic interferometer. We observe an abrupt shift of the interference fringes by half a period in the bias range of the zero-bias anomaly, a behavior which cannot be reproduced by single-particle models. We instead relate it to the phase shift experienced by electrons scattering off a Kondo system. Our experiment therefore provides new evidence of this many-body effect in quantum point contacts.

Abstract
OBJECTIVES This study evaluated the extent to which oral chronic graft-versus-host disease (cGVHD) consensus assessments are predictive of management across institutions with and without oral medicine (OM) centers, and whether ancillary care guidelines are followed within clinical practice. METHODS Longitudinal oral cGVHD data were abstracted from the cGVHD Consortium, and additional mouth-specific management data were analyzed across five transplant centers. RESULTS Seventy-nine patients with 656 visits were observed for a median of 7.1 months with one visit per follow-up month. Ancillary therapies for oral cGVHD were prescribed for 67% of patients for a median of 0.46 months (per follow-up month) at OM centers and 0.78 months at non-OM centers. Patients treated with ancillary therapy were more likely to have an National Institutes of Health (NIH) mouth score of ≥1 (P < 0.001, odds ratio: 5.1) and mouth pain (P = 0.01, odds ratio: 2.6). The odds ratios of receiving ancillary therapy from OM experts were higher than transplant physicians (53%; P = 0.03). CONCLUSIONS Oral cGVHD consensus assessments corresponding with ancillary therapy use were mouth pain and NIH mouth score, with higher odds ratios of receiving therapy from OM experts. Ancillary care guidelines for oral cGVHD are reflected in academic clinical practice with respect to utilization of recommended prescriptions.

Abstract
Low-complexity regions are sub-sequences of biased composition in a protein sequence. The influence of these regions over protein evolution, specific functions and highly interactive capacities is well known. Although protein sequence entropy has been largely studied, its relationship with low-complexity regions and the subsequent effects on protein function remains unclear. In this work we propose a theoretical and empirical model integrating the sequence entropy with local complexity parameters. Our results indicate that the protein sequence entropy is related with the protein length, the entropies inside and outside the low-complexity regions as well as their number and average size. We found a small but significant increment in the sequence entropy of hubs proteins. In agreement with our theoretical model, this increment is highly dependent of the balance between the increment of protein length and average size of the low-complexity regions. Finally, our models and proteins analysis provide evidence supporting that modifications in the average size is more relevant in hubs proteins than changes in the number of low-complexity regions.

Abstract
Thrombotic microangiopathy or "TMA" including thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS) became a public health problem following the European outbreak of E. coli (O104:H4) gastroenteritis in 2011. A rapid diagnosis and therapy in an intensive care unit provide better patient survival and lower cost for society. Supportive treatment has significantly improved the prognosis over the past decade and includes fresh frozen plasma for TTP, plasmapheresis for HUS, and recently a new therapeutic agent: anti-C5 antibodies. We will provide in this article, through the current literature and four cases encountered in our department, to establish an algorithm to manage patients with TMA.
