Abstract
Anti-Müllerian hormone (AMH) has a conserved role in regulating the reproductive cycle in several species. Its circulating concentration reflects the size of the growing primordial follicle reserve and is a reliable predictor of superovulation response in embryo/oocyte donors. This study investigated the possible application of AMH measurement in dromedary camels (Camelus dromedarius) multiple ovulation embryo transfer programs. In experiment 1, the follicular cycle of synchronized and naturally cycling camels (n = 12) was monitored. Blood was collected at 6 timepoints in 2 consecutive cycles corresponding to emergence, mid-cycle, and dominance in both group and hormonal fluctuations were evaluated for repeatability of measurements within and between cycles. In experiment 2, the correlation between circulating AMH concentrations prior to initiation of superovulation and the outcome of superovulation was evaluated. The results were compared between donors with higher (n = 7) and lower than median (n = 8) AMH values. Mean AMH concentrations in synchronized and non-synchronized camels were 1.46 ± 0.15 and 0.95 ± 0.09, respectively. Intercycle and intracycle values of AMH showed high repeatability in camels of both groups (>96.4% and >92.74%, respectively) with significant correlations between values at different stages of the ovarian cycle (Emergence and mid-cycle: R2 = 0.82; emergence and. dominance: R2 = 0.86; Mid-cycle and dominance: R2 = 0.93, P < 0.05). Total follicles, CLs, and recovered embryos were highly correlated with AMH values prior to superovulation (R2 = 0.64, R2 = 0.77, and R2 = 0.64, respectively, P < 0.05). A greater number of developed follicles prior to mating (17.00 ± 2.09 vs. 7.62 ± 1.06), CLs (12.58 ± 1.36 vs. 5.12 ± 0.93), transferable (10.85 ± 1,31 vs. 3.37 ± 0.82), and spherical embryos (8.14 ± 1.07 vs. 2.62 ± 0.7) were observed in camels with higher than median concentrations of AMH (P < 0.05). Fluctuations in estradiol and progesterone did not affect variations in mean AMH values (r2 < 0.19 and r2 < 0.24, respectively, P > 0.05). In conclusion, highly consistent AMH values in dromedary camels are a reliable predictor of superovulation response and outcome in dromedary camels.

Abstract
The use of 3D-printed hydroxyapatite (HA) scaffolds for stimulating bone healing has been increasing over the years. Although all the promising effects of these scaffolds, there are still few studies and limited understanding of their interaction with bone tissue and their effects on the process of fracture healing. In this context, this study aimed to perform a systematic literature review examining the effects of different 3D-printed HA scaffolds in bone healing. The search was made according to the preferred reporting items for systematic reviews and meta-analysis (PRISMA) orientations and Medical Subject Headings (MeSH) descriptors "3D printing," "bone," "HA," "repair," and "in vivo." Thirty-six articles were retrieved from PubMed and Scopus databases. After eligibility analyses, 20 papers were included (covering the period of 2016 and 2021). Results demonstrated that all the studies included in this review showed positive outcomes, indicating the efficacy of scaffolds treated groups in the in vivo experiments for promoting bone healing in different animal models. In conclusion, 3D-printed HA scaffolds are excellent candidates as bone grafts due to their bioactivity and good bone interaction.

Abstract
BACKGROUND Rubella is an infection caused by rubella virus (RV) and is generally regarded as a mild childhood disease. The disease continues to be of public health importance mainly because when the infection is acquired during early pregnancy it often results in fetal abnormalities, which are classified as congenital rubella syndrome (CRS). An accurate diagnosis for rubella is thus of pivotal importance for proper treatment. OBJECTIVE To produce a recombinant multiepitope protein (rMERUB) for the diagnosis of rubella, based on conserved immunodominant epitopes of glycoprotein E1 and E2. METHODS A synthetic gene was designed and cloned into vector pET21a with a 6xHis tag at the C-terminal for affinity purification and overexpressed in Escherichia coli cells. Biophysical analysis of rMERUB was performed by circular dichroism. Biological activity was assessed using an in-house ELISA assay. RESULTS Expression in Escherichia coli showed a ~22 kDa protein that was purified and used to perform structural assays and an IgG ELISA. Structural analyses reveal rMERUB has a β leaf pattern that promotes the exposure of epitopes, thus allowing antibody recognition. Evaluation of 33 samples (22=positive; 11=negative) was performed using in-house ELISA and this was compared with a commercial kit. The sensitivity was 100% (95% CI: 85-100) and specificity 90.91% (95% CI: 62-99). Excellent agreement (Kappa index = 0.9) was obtained between ELISA assays. CONCLUSIONS The careful choice of epitopes and the high epitope density, coupled with simple-step purification, pinpoints rMERUB as a promising alternative for rubella diagnosis, with potential for the development of a diagnostic kit.

Abstract
Introduction The most frequent complaints from children referred to psychiatry and psychologist are related to academic and attentional impairments, or developmental delay, which are shared by many conditions. Objectives To develop an inventory that evaluates cognitive functions of children between 6 to 11 years old to track cognitive profiles compatible with Intellectual Disability, ADHD, and dyslexia to assist in differential diagnosis. Methods In study 1 (identification of the relevant constructs, operational definition, and items development), data were collected from parents of children and professionals who serve this population; articles, verification of screening instruments and identification of cognitive impairments by the DSM-5. In study 2, an analysis of judges with professionals was carried out, as well as a verification of the items’ clarity by the target population; In study 3, we looked for evidence of validity and precision indicators with a sample of 272 parents and 178 teachers of 72 children diagnosed with one of the three disorders and 207 that had no suspect of neurodevelopmental disorders. Results For the parent version, the four-factor solution was the most appropriate, with the following Scales: Attention, Executive Functions, Intelligence and Oral Language. The final version for parents was composed of 60 items, with excellent internal consistency indices (coefficients> 0.90). Conclusions ROC curves expressed good sensitivity and specificity of the scales for each disorder. Future studies have to expand the sample size of children diagnosed with one of the three disorders so that new analyzes can be performed and the results can be generalizable to the population. Disclosure No significant relationships.

Abstract
EVIPNet Brazil was launched in 2007, coordinated by the Ministry of Health. Its expansion has promoted the institutionalization of a national knowledge translation platform, and has also been active at the local level. Local Health Evidence Labs were implemented to institucionalize working groups linked to EVIPNet. In this multiple case study, we discuss the advances in the institutionalization of Evidence-Informed Policy-making in Brazil, based on a mapping of the Health Evidence Labs' institutional capacity to acquire, evaluate, adapt and apply evidence and analyzed organizational arrangements and implementation barriers. The coordinators of 15 responded to a self-assessment questionnaire from the Canadian Health Services Research Foundation. The main products reported are evidence briefs and deliberative dialogues focused on regional problems, training activities and different kinds of rapid responses. Health Evidence Labs have the resources to acquire and evaluate research evidence, but have a low capacity to adapt and apply evidence, indicating that they do not have all the factors (skills, structures, processes, and organizational culture) to promote and use research results in decision-making. The lower capacity to 'adapt' and 'apply' evidence may be related to low development of exchange process with external experts. Governance is joined between managers of the departments with technical bodies; the service provision occurs to attend internal and external demands; financing is public or utilizing public research calls. The implementation barriers described are the staff turnover, inadequate funding arragements for develop knowledge translation products, paid access to evidence databases, lack of a repository for their production, and lack of monitoring and evaluation. Brazil has improved in the institutionalization of evidence-informed policy but still some important barriers to achieve a complete national knowledge translation platform.
Key messages
Brazil has institutionalized evidence-informed policy from the structuring of EVIPNet Brazil Network. To achieve the network sustainability, it is vital to consider the alignment of organizational elements with an emphasis on governance, financing, and its monitoring.

Abstract
Objective To identify potential microRNA (miRNA) biomarkers of poor, normal and hyperresponse to controlled ovarian stimulation (COS). Methods In the present study, we assessed 40 serum samples from patients undergoing COS. We used ten samples to standardize miRNAs detection in the serum. The remaining 30 samples were split into three groups depending on the patient's response to COS: poor response (PR group, n=10), normal response (NR group, n=10), and hyperresponse (HR group, n=10). Aberrantly expressed miRNAs were identified using a large-scale expression analysis platform. Gene set enrichment analysis was performed to assess the biological processes potentially modulated by the identified miRNAs. Results Twenty-two miRNAs were detected only in the PR or HR groups when compared with the NR group. From those, 11 presented poor dissociation curves and were excluded from further analysis. A bioinformatics analysis revealed that the selected 11 miRNAs target several genes involved in GnRH, estrogen and prolactin signaling, oocyte maturation, female pregnancy, and meiosis. Conclusion The large-scale analysis of miRNA expression identified distinct miRNA profiles for poor and hyperresponse to COS, which potentially modulate key processes for human assisted reproduction. All evidence suggests that the serum microRNA profiling may discriminate patients who will respond in an exacerbated manner from those who will respond insufficiently to COS. Further studies may validate these miRNAs, enabling the individualization of treatment and more successful outcomes.

Abstract
The couple from this clinical case consisted of a 55 years old male with an obstructive interval of 25 years post vasectomy, and a 38 years old female partner. Both partners had normal results in infertility workup. Five mature oocytes were injected with motile spermatozoa showing morphological alterations, obtained by percutaneous epididymal sperm aspiration. Four oocytes fertilized, and three embryos were transferred with assisted hatching on day three of development, of which one was a high-quality embryo. A clinical pregnancy was confirmed by the detection of two gestational sacs with foetal heartbeats. Pregnancy was ongoing during the submission of this manuscript. The use of ICSI with PESA/TESA should be considered as a feasible alternative when vasectomy reversal fails in vasectomized men wishing to father again. Case reports like this may inspire the counseling of couples that have suffered from a previous vasectomy reversal failure and support the recommendation of ICSI with PESA treatment, which could allow those couples to have their own children, even in the presence of advanced parental age.

Abstract
Noninvasive collection of cells used for generation of induced pluripotent stem cells (iPSC) generation would simplify its use for regenerative and reproductive purposes in veterinary medicine, although it is still unpublished in species other than humans. This study aimed to derive urine progenitor cells (UPCs) invitro from urine samples collected from swine, and then to reprogram them into iPSCs. For that, urine samples were collected from three females, and cells were isolated and cultured from each following the human UPCs protocol (Steichen et al. 2017 Curr. Protoc. Hum. Genet. 21, 7.1-21.7.22; https://doi.org/10.1002/cphg.26). Approximately 200mL of urine samples were collected in sterile flasks and centrifuged at 300×g; the pellet was washed in Dulbecco's PBS, resuspended, and cultured in 45% Dulbecco's modified Eagle's medium (DMEM)-high glucose, 5% fetal bovine serum (FBS), 50% Renal Epithelial Cell Growth basal medium (REBM) supplemented with 1% glutamine, 1% nonessential amino acids (NEAA), penicillin/streptomycin (P/S), and REGM supplements hEGF, insulin, hydrocortisone, GA-1000, FBS, transferrin, triiodothyronine, epinephrine (Lonza), and 10ngmL−1 basic fibroblast growth factor (bFGF). The UPCs first colonies were observed approximately 1 week after and resembled epithelial-like cells. At passage 2, one cell line was transduced with murine OCT4, SOX2, KLF4, and C-MYC cDNAs (OSKM) using a lentiviral vector. After 5 days, cells were plated onto mouse embryonic fibroblasts and cultured in knockout DMEM/F12, 20% knockout serum replacement, NEAA, L-glutamine, 2-mercaptoethanol, and P/S supplemented with 10ngmL−1 bFGF. Efficiency of reprogramming was 8.45%, measured by analysing the number of typical iPSC colonies relative to the transduced cells plated, after ~12 days. Three clonal lines (C1, C4, and C6) were maintained invitro and characterised regarding pluripotency markers for at least 30 passages. All three lines were positive for alkaline phosphatase activity in passages 15 and also 22. Immunocytochemistry analysis revealed that C6 (passage 22) was positive for the pluripotency genes OCT4 (1:100, SC), SOX2 (1:500, AB), SSEA1 (1:50, SC), TRA1- 81 (1:50, Millipore), and NANOG (1:100, AB), whereas C1 and C4 (passages 23 and 22, respectively) were positive only for OCT4, SOX2, and SSEA1. The expression of exogenous and endogenous pluripotency factors (OCT4, SOX2, and NANOG) was evaluated by qRT-PCR, comparing the three clonal lines at passages 16/17 and 21/22 and comparing different passages (10, 11, 14, 17, and 22) on C1 line. No statistical difference was observed between cell lines when compared in different passages, perhaps because of the great variation between lines. However, analysis of C1 line over time showed that pluripotency genes increased and exogenous vector expression decreased during early passages (±10 passages); however, after passage 17, OCT4 and NANOG decreased whereas SOX2 and exogenous vector expression increased. In conclusion, it was possible to reprogram UPCs into iPSCs and maintain them in culture for at least 30 passages; however, iPSCS were dependent on exogenous factors. These results represent the partial reprogramming of UPCs to iPSCs in animals for the first time, enabling the generation of invitro disease models using a noninvasive method.

Abstract
BACKGROUND Paracentral acute middle maculopathy is defined as ischemia of the deep retinal layers. We report an unusual case of paracentral acute middle maculopathy associated with hypoperfusion of the cilioretinal artery and impending central retinal vein occlusion in a young male with no previous comorbidities. CASE REPORT The patient was a 22-year-old male complaining about a sudden loss of vision in his right eye upon awakening. Fundus examination showed optic disk edema, and increased tortuosity of the retinal veins and a few retinal hemorrhages. Swept-source optical coherence tomography found a hyperreflective band that was more pronounced at the level of the inner nuclear layer of the retina. These findings led us to a diagnosis of paracentral acute middle maculopathy associated with hypoperfusion of the cilioretinal artery. CONCLUSION The finding of paracentral acute middle maculopathy on optical coherence tomography demands a proper investigation of its cause, because it has an intimate association with vascular diseases and is not an isolated entity. In our case, we could not identify the etiology of the unilateral event in this young male, although dehydration due to alcohol consumption and subsequent hypotension might have played a role in this ischemic event.

Abstract
Sirtuin 3 (SIRT3) is a NAD+-dependent deacetylase downregulated in aging and age-associated diseases such as cancer and neurodegeneration and in high-fat diet (HFD)-induced metabolic disorders. Here, we performed a small-molecule screen and identified an unexpected metabolic vulnerability associated with SIRT3 loss. Azaserine, a glutamine analog, was the top compound that inhibited growth and proliferation of cells lacking SIRT3. Using stable isotope tracing of glutamine, we observed its increased incorporation into de novo nucleotide synthesis in SIRT3 knockout (KO) cells. Furthermore, we found that SIRT3 KO cells upregulated the diversion of glutamine into de novo nucleotide synthesis through hyperactive mTORC1 signaling. Overexpression of SIRT3 suppressed mTORC1 and growth in vivo in a xenograft tumor model of breast cancer. Thus, we have uncovered a metabolic vulnerability of cells with SIRT3 loss by using an unbiased small-molecule screen.

Abstract
Despite considerable efforts to identify cancer metabolic alterations that might unveil druggable vulnerabilities, systematic characterizations of metabolism as it relates to functional genomic features and associated dependencies remain uncommon. To further understand the metabolic diversity of cancer, we profiled 225 metabolites in 928 cell lines from more than 20 cancer types in the Cancer Cell Line Encyclopedia (CCLE) using liquid chromatography-mass spectrometry (LC-MS). This resource enables unbiased association analysis linking the cancer metabolome to genetic alterations, epigenetic features and gene dependencies. Additionally, by screening barcoded cell lines, we demonstrated that aberrant ASNS hypermethylation sensitizes subsets of gastric and hepatic cancers to asparaginase therapy. Finally, our analysis revealed distinct synthesis and secretion patterns of kynurenine, an immune-suppressive metabolite, in model cancer cell lines. Together, these findings and related methodology provide comprehensive resources that will help clarify the landscape of cancer metabolism.

Abstract
We describe here the agreed upon first development steps and priority objectives of a community engagement effort to address current challenges in quality assurance (QA) and quality control (QC) in untargeted metabolomic studies. This has included (1) a QA and QC questionnaire responded to by the metabolomics community in 2015 which recommended education of the metabolomics community, development of appropriate standard reference materials and providing incentives for laboratories to apply QA and QC; (2) a 2-day 'Think Tank on Quality Assurance and Quality Control for Untargeted Metabolomic Studies' held at the National Cancer Institute's Shady Grove Campus and (3) establishment of the Metabolomics Quality Assurance and Quality Control Consortium (mQACC) to drive forward developments in a coordinated manner.

Abstract
Enhancer profiling is a powerful approach for discovering cis-regulatory elements that define the core transcriptional regulatory circuits of normal and malignant cells. Gene control through enhancer activity is often dominated by a subset of lineage-specific transcription factors. By integrating measures of chromatin accessibility and enrichment for H3K27 acetylation, we have generated regulatory landscapes of chronic lymphocytic leukemia (CLL) samples and representative cell lines. With super enhancer-based modeling of regulatory circuits and assessments of transcription factor dependencies, we discover that the essential super enhancer factor PAX5 dominates CLL regulatory nodes and is essential for CLL cell survival. Targeting enhancer signaling via BET bromodomain inhibition disrupts super enhancer-dependent gene expression with selective effects on CLL core regulatory circuitry, conferring potent anti-tumor activity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The management of diabetes mellitus management in African communities, especially in Gabon, is not well established as more than 60% of population rely on traditional treatments as primary healthcare. The aim of this review was to collect and present the scientific evidence for the use of medicinal plants that are in currect by Gabonese traditional healers to manage diabetes or hyperglycaemia based here on the pharmacological and toxicological profiles of plants with anti-diabetic activity. There are presented in order to promote their therapeutic value, ensure a safer use by population and provide some bases for further study on high potential plants reviewed. MATERIALS AND METHODS Ethnobotanical studies were sourced using databases such as Online Wiley library, Pubmed, Google Scholar, PROTA, books and unpublished data including Ph.D. and Master thesis, African and Asian journals. Keywords including 'Diabetes', 'Gabon', 'Toxicity', 'Constituents', 'hyperglycaemia' were used. RESULTS A total of 69 plants currently used in Gabon with potential anti-diabetic activity have been identified in the literature, all of which have been used in in vivo or in vitro studies. Most of the plants have been studied in human or animal models for their ability to reduce blood glucose, stimulate insulin secretion or inhibit carbohydrates enzymes. Active substances have been identified in 12 out of 69 plants outlined in this review, these include Allium cepa and Tabernanthe iboga. Only eight plants have their active substances tested for anti-diabetic activity and are suitables for further investigation. Toxicological data is scarce and is dose-related to the functional parameters of major organs such as kidney and liver. CONCLUSION An in-depth understanding on the pharmacology and toxicology of Gabonese anti-diabetic plants is lacking yet there is a great scope for new treatments. With further research, the use of Gabonese anti-diabetic plants is important to ensure the safety of the diabetic patients in Gabon.

Abstract
Abstract
INTRODUCTION: Nipple sparing mastectomy (NSM) consists in the complete excision of the breast gland, mantaining the subcutaneous tissue, skin and nipple-areola complex (NAC). Recently, the NSM was developed as a therapeutic option not just for the patients that need risk-reducing surgery, but also for patients that have tumors not involving the NAC.
OBJECTIVES: Evaluate the overall survival, disease-free survival and local recurrence of the patients that underwent NSM. The only exclusion criteria for NSM was lesion at the NAC.
MATERIAL AND METHODS: Retrospective study that evaluate the number of cases of NSM performed between 2003 and 2015 in a private sector in the south of Brazil.
RESULTS: A total of 224 patients underwent NSM during the period of 2003-2015. The mean age was 47 years. From the total, 43 patients underwent risk-reducing NSM and 181 therapeutic NSM (64 unilateral and 117 bilateral). In those cases of bilateral procedures all of them underwent risk-reducing surgery on the contralateral breast (there were no bilateral cancers). Of this 181 cases, 108 (59%) have familiar history of breast cancer, considering first, second and third-degree relatives. Twenty six patients (14%) have history of previous breast cancer diagnosed. In this group of 181 patients with therapeutic NSM, 29 (16%) developed any unfavorable outcomes, 13 (7%) local recurrence, 4 (2%) ipsilateral node recurrence, 3 (1,6%) contralateral recurrence and 9 (5%) distant metastasis. None of the local recurrences occurred at the NAC, neither the cited unfavorable outcomes occurred in the risk-reducing setting. In a median follow-up of 47,7 months, the overall survival was 95% (8 deaths related to breast cancer) and the disease-free survival was 83,7%.
CONCLUSIONS: The overall survival rates of 95% at 47 months of follow-up is similar to the literature rates, that range from 93 to 97% in 5 years, depending on study's inclusion criterias. In our study, 14% of patients had previous breast cancer and 59% of patients treated for breast cancer by NSM had positive familiar history of breast cancer. This results in an unselected group of patients confirms the safety of this therapeutic method as an option for breast cancer patients.

Abstract
Processive elongation of RNA Polymerase II from a proximal promoter paused state is a rate-limiting event in human gene control. A small number of regulatory factors influence transcription elongation on a global scale. Prior research using small-molecule BET bromodomain inhibitors, such as JQ1, linked BRD4 to context-specific elongation at a limited number of genes associated with massive enhancer regions. Here, the mechanistic characterization of an optimized chemical degrader of BET bromodomain proteins, dBET6, led to the unexpected identification of BET proteins as master regulators of global transcription elongation. In contrast to the selective effect of bromodomain inhibition on transcription, BET degradation prompts a collapse of global elongation that phenocopies CDK9 inhibition. Notably, BRD4 loss does not directly affect CDK9 localization. These studies, performed in translational models of T cell leukemia, establish a mechanism-based rationale for the development of BET bromodomain degradation as cancer therapy.

Abstract
Cellular signaling is often propagated by multivalent interactions. Multivalency creates avidity, allowing stable biophysical recognition. Multivalency is an attractive strategy for achieving potent binding to protein targets, as the affinity of bivalent ligands is often greater than the sum of monovalent affinities. The BET family of transcriptional coactivators features tandem bromodomains, through which BET proteins naturally bind acetylated histones and transcription factors. All reported BRD4 antagonists bind in a monovalent fashion. Here, we report the first bivalent BET bromodomain inhibitor, MT1 that has unprecedented potency. Biophysical and biochemical studies suggest MT1 is an intramolecular bivalent BRD4 binder that is over 100-fold more potent in cellular assays compared to the corresponding monovalent antagonist, JQ1. MT1 significantly delayed leukemia progression in mice (Mus musculus) compared to JQ1. These data qualify a powerful chemical probe for BET bromodomains and extensible rationale for further development of multidomain epigenetic reader protein inhibitors.

Abstract
Spontaneous dissecting aneurysms (SDAs) seldom involve the intradural vertebral artery VA, the posterior cerebral, basilar or postero inferior cerebellar arteries (PICAs), where they produce subarachnoid haemorrhage and/or ischaemia. These lesions may develop spontaneously or occasionally after minor trauma and occur in young people in whom there is no underlying abnormality to explain the appearance of the dissection in most cases. Spontaneous dissecting aneurysm of the PICA is rare and its natural history is not well understood. Surgery or endovascular treatment for PICA dissection remain controversial because they suggest vessel occlusion. Only in a few cases is the bypass between the occipital artery and the PICA possible with trapping of the dissected segment. Reinforcement of the arterial wall does not seem efficient and the surgical approach per se with sole exclusion of the aneurysm may be disastrous. We describe two cases of SDA of PICA that presented with subarachnoid haemorrhage (SAH), treated conservatively, with spontaneous cure of the lesions, angiographically confirmed at mid-time follow-up of five and four months. These favourable spontaneous thromboses, like 11 other similar case reported in the literature, did not show any rebleed. The possibility of a benign clinical course of this lesion exists; clinical and angiographic management of the patient before a decision for a aggressive treatment is proposed.

Abstract
BACKGROUND Pulmonary hypertension and associated right ventricular (RV) dysfunction are important determinants of morbidity and mortality, which are optimally characterized by invasive hemodynamic measurements. OBJECTIVES This study sought to determine whether metabolite profiling could identify plasma signatures of right ventricular-pulmonary vascular (RV-PV) dysfunction. METHODS We measured plasma concentrations of 105 metabolites using targeted mass spectrometry in 71 individuals (discovery cohort) who underwent comprehensive physiological assessment with right-sided heart catheterization and radionuclide ventriculography at rest and during exercise. Our findings were validated in a second cohort undergoing invasive hemodynamic evaluations (n = 71), as well as in an independent cohort with or without known pulmonary arterial (PA) hypertension (n = 30). RESULTS In the discovery cohort, 21 metabolites were associated with 2 or more hemodynamic indicators of RV-PV function (i.e., resting right atrial pressure, mean PA pressure, pulmonary vascular resistance [PVR], and PVR and PA pressure-flow response [ΔPQ] during exercise). We identified novel associations of RV-PV dysfunction with circulating indoleamine 2,3-dioxygenase (IDO)-dependent tryptophan metabolites (TMs), tricarboxylic acid intermediates, and purine metabolites and confirmed previously described associations with arginine-nitric oxide metabolic pathway constituents. IDO-TM levels were inversely related to RV ejection fraction and were particularly well correlated with exercise PVR and ΔPQ. Multisite sampling demonstrated transpulmonary release of IDO-TMs. IDO-TMs also identified RV-PV dysfunction in a validation cohort with known risk factors for pulmonary hypertension and in patients with established PA hypertension. CONCLUSIONS Metabolic profiling identified reproducible signatures of RV-PV dysfunction, highlighting both new biomarkers and pathways for further functional characterization.

Abstract
The development of effective pharmacological inhibitors of multidomain scaffold proteins, notably transcription factors, is a particularly challenging problem. In part, this is because many small-molecule antagonists disrupt the activity of only one domain in the target protein. We devised a chemical strategy that promotes ligand-dependent target protein degradation using as an example the transcriptional coactivator BRD4, a protein critical for cancer cell growth and survival. We appended a competitive antagonist of BET bromodomains to a phthalimide moiety to hijack the cereblon E3 ubiquitin ligase complex. The resultant compound, dBET1, induced highly selective cereblon-dependent BET protein degradation in vitro and in vivo and delayed leukemia progression in mice. A second series of probes resulted in selective degradation of the cytosolic protein FKBP12. This chemical strategy for controlling target protein stability may have implications for therapeutically targeting previously intractable proteins.

Abstract
![]()
The
DOT1L lysine methyltransferase has emerged as a validated therapeutic
target in MLL-rearranged (MLLr) acute leukemias.
Although S-adenosylmethionine competitive inhibitors have demonstrated
pharmacological proof-of-principle in MLLr-leukemia,
these compounds require further optimization to improve cellular potency
and pharmacokinetic stability. Limiting DOT1L inhibitor discovery
and ligand optimization have been complex biochemical methods often
using radionucleotides and cellular methods requiring prolonged culture.
We therefore developed a new suite of assay technologies that allows
comparative assessment of chemical tools for DOT1L in a miniaturized
format. Coupling these assays with structural information, we developed
new insights into DOT1L ligand binding and identified several functionalized
probes with increased cellular potency (IC50 values ∼10
nM) and excellent selectivity for DOT1L. Together these assay technologies
define a platform capability for discovery and optimization of small-molecule
DOT1L inhibitors.

Abstract
Endophytic microorganisms consist of fungi, bacteria, and actinomycetes that play important roles in the process of plant adaptation to the environment. Currently, the natural associations between microorganisms and plant species are being explored for a large number of biotechnological applications. In this study, 122 endophytic bacteria were isolated from 5 cultivars of Musa spp from the state of Amazonas (Brazil). Four strains were selected because they exhibited antagonistic activities against Fusarium oxysporum f. sp cubense and Colletotrichum guaranicola, with inhibitions ranging from 19 to 30% and 27 to 35%, respectively. Phylogenetic analysis of the 16S rDNA regions of these bacteria with antifungal activity showed that they are phylogenetically related to 3 different species of Bacillus - B. amyloliquefaciens, B. subtilis subsp subtilis, and B. thuringiensis.

Abstract
Most patients with pancreatic ductal adenocarcinoma (PDAC) are diagnosed with advanced disease and survive less than 12 months. PDAC has been linked with obesity and glucose intolerance, but whether changes in circulating metabolites are associated with early cancer progression is unknown. To better understand metabolic derangements associated with early disease, we profiled metabolites in prediagnostic plasma from individuals with pancreatic cancer (cases) and matched controls from four prospective cohort studies. We find that elevated plasma levels of branched-chain amino acids (BCAAs) are associated with a greater than twofold increased risk of future pancreatic cancer diagnosis. This elevated risk was independent of known predisposing factors, with the strongest association observed among subjects with samples collected 2 to 5 years before diagnosis, when occult disease is probably present. We show that plasma BCAAs are also elevated in mice with early-stage pancreatic cancers driven by mutant Kras expression but not in mice with Kras-driven tumors in other tissues, and that breakdown of tissue protein accounts for the increase in plasma BCAAs that accompanies early-stage disease. Together, these findings suggest that increased whole-body protein breakdown is an early event in development of PDAC.

Abstract
The Enterobacterial repetitive intergenic consensus (ERIC) marker was used to analyze the genetic variability of Mycosphaerella fijiensis, the causative agent of Black Sigatoka disease in banana plants. A total of 123 isolates were used, which were divided into populations based on their original hosts and collection sites in Brazil. A total of 9 loci were amplified, 77.8% of which were found to be polymorphic. The genetic diversity found in the population was 0.20. Analysis of molecular variance (AMOVA) demonstrated that the highest level of genetic variation is within populations. Cluster analysis revealed three main groups in Brazil, with no correlation between geographic and genetic distance.

Abstract
The effect of meteorological variables on surface ozone (O3) concentrations was analysed based on temporal variation of linear correlation and artificial neural network (ANN) models defined by genetic algorithms (GAs). ANN models were also used to predict the daily average concentration of this air pollutant in Campo Grande, Brazil. Three methodologies were applied using GAs, two of them considering threshold models. In these models, the variables selected to define different regimes were daily average O3 concentration, relative humidity and solar radiation. The threshold model that considers two O3 regimes was the one that correctly describes the effect of important meteorological variables in O3 behaviour, presenting also a good predictive performance. Solar radiation, relative humidity and rainfall were considered significant for both O3 regimes; however, wind speed (dispersion effect) was only significant for high concentrations. According to this model, high O3 concentrations corresponded to high solar radiation, low relative humidity and wind speed. This model showed to be a powerful tool to interpret the O3 behaviour, being useful to define policy strategies for human health protection regarding air pollution.

Abstract
Background: Chrysophyllum pruniforme of family sapotaceae is a plant used in traditional medicine in Gabon. Materials and Methods: In this study, C. pruniforme barks were subjected to phytochemical screening and cytotoxicity investigations. Different concentrations of aqueous and total phenolic extract were tested on mice and on human erythrocytes. Results: Phytochemical screening of C. pruniforme barks revealed the presence of flavonoids, saponins, and tannins, reducing sugars, polyphenols and traces of anthraquinones. When tested in vitro, aqueous and the phenolic extracts showed hemolytic activities on human erythrocytes with phenolic compounds being more cytotoxic than aqueous extracts. In vivo study of toxicity, allowed to determine the LD50 at 90 mg/kg for the doses of 50, 150 and 250 mg/kg of body weight. Conclusion: These data indicate in one hand that C. pruniforme is rich in phenolic compounds and that the aqueous and total phenolic extracts could be considered as toxic for mice and maybe potentially toxic to humans in the other hand.

Abstract
Obesity is a disease that has become a serious public health issue worldwide, and chronic stressors, which are a problem for modern society, cause neuroendocrine changes with alterations in food intake. Obesity and chronic stress are associated with the development of cardiovascular diseases and metabolic disorders. In this study, a rat model was used to evaluate the effects of a hypercaloric diet plus chronic restraint stress on the serum leptin and lipids levels and on the weight of specific adipose tissue (mesenteric, MAT; subcutaneous, SAT and visceral, VAT). Wistar rats were divided into the following 4 groups: standard chow (C), hypercaloric diet (HD), stress plus standard chow (S), and stress plus hypercaloric diet (SHD). The animals in the stress groups were subjected to chronic stress (placed inside a 25 cm × 7 cm plastic tube for 1h per day, 5 days per week for 6 weeks). The following parameters were evaluated: the weight of the liver, adrenal glands and specific adipose tissue; the delta weight; the Lee index; and the serum levels of leptin, corticosterone, glucose, total cholesterol, and triglycerides. The hypercaloric diet induced obesity in rats, increasing the Lee index, weight, leptin, triglycerides, and cholesterol levels. The stress decreased weight gain even in animals fed a hypercaloric diet but did not prevent a significant increase in the Lee index. However, an interaction between the independent factors (hypercaloric diet and stress) was observed, which is demonstrated by the increased serum leptin levels in the animals exposed to both protocols.

Abstract
The production and quality of eucalyptus plantations have been studied in areas with different densities of ant nests, being important to estimate losses caused by leaf-cutting ants. The effects of leaf-cutting ant on wood production in differents productivity sites were studied in eucalyptus plantations in the region of Atlantic Forest, Minas Gerais State, Brazil from 2003 to 2006. Data of plots of the continuous forest inventory and data of leaf-cutting ant monitoring in eucalyptus plantations were obtained. Each unitary increment in the area of Atta spp. nests per hectare reduced the wood production of the eucalyptus forest between 0.04 and 0.13 m³.ha(-1), resulting in a level of economic damage for leaf-cutting ants between 13.4 and 39.2 m².ha(-1), in this region. Moreover, this study innovated when using indices of forest productivity (site index) that promote better adjustment of the models and produce estimate more accurate of the level of economic damage for leaf-cutting ants in cultivated forests, allowing to conclude that the increase of the total area of ant nests reduces the wooden volume of eucalyptus, proportionally to the productive potential of the forest.
