title: A rare case of deafness and renal abnormalities in HDR syndrome caused by a de novo mutation in the GATA3 gene

description: Abstract HDR syndrome is a rare autosomal dominant disorder caused by mutations in the GATA3 gene and characterized by hypoparathyroidism, sensorineural deafness and renal abnormalities. Here we report a Brazilian family, from which the proband, his mother and his grandfather were diagnosed with bilateral sensorineural hearing loss. Molecular screening of the GJB2, GJB6 and MTRNR1 genes in the proband showed no alterations; however, whole exome sequencing detected a heterozygous mutation, c.1099C &gt; T (p.Arg367*), in the GATA3 gene. Segregation analyses showed that the mother also had the mutation, but not the grandparents, hence indicating a different hearing impairment type for the grandfather. Paternity test of the mother of the proband confirmed that she has a de novo mutation. Furthermore, HDR syndrome was confirmed with new clinical evaluations showing right kidney agenesis in the proband. This is the first study reporting only deafness and renal abnormalities as symptoms of the p.Arg367* mutation in the GATA3 gene, and also the sixth HDR syndrome case in the world, and the first on the American continent. Together with other reported cases, this study highlights the variability of HDR syndrome symptoms in individuals with the p.Arg367* mutation, emphasizing the importance of molecular analyses for correct diagnosis.

title: Diatom assemblages (Bacillariophyta) in six tropical reservoirs from southeast Brazil: species composition and spatial and temporal variation patterns

description: Abstract Aim Relationships between species composition and variation patterns in diatom assemblages over six tropical reservoirs located in Southeast Brazil were explored. Methods Surface-sediment and phytoplankton diatom assemblages were determined and Canonical Correspondence Analysis was used to verify the set of environmental variables that best explain the species composition variation among sites. Results A total of 28 diatom taxa representing 20 genera were identified using light and scanning electron microscopy. Information on their ecological preferences was also provided. Humidophila biscutella is reported for the first time in Brazil whereas Sellaphora sassiana and Humidophila brekkaensis are reported for the first time in São Paulo State. Three groups of potential water quality indicators were delineated: the first suggests oligotrophic conditions, the second is related to cold waters with low luminosity in a mixing regime, and the third is a small group of tolerant species occurring in water with high conductivity, pH and total phosphorus conditions. Conclusion present study provided the first insight into the general diatom communities over six tropical reservoirs in Southeast Brazil and provided information on their ecology and distribution aiming bioassessment. The potential of water quality indicator diatom groups here outlined are in line with those reported in the literature and reinforce the importance of PEJU for the maintenance of ecological quality of reservoirs and reference conditions for the Metropolitan Region of São Paulo water sources.

title: LOSS OF DESICCATION TOLERANCE IN SEEDS OF TREE SPECIES DURING GERMINATION: THEORETICAL AND PRACTICAL IMPLICATIONS

description: ABSTRACT Understanding the loss of desiccation tolerance is of great importance in seed technology for its implications in the development of strategies for seed conservation and seedling production. In the present work, the loss of desiccation tolerance was studied in seeds of tree species Bowdichia virgilioides, Libidibia ferrea, Cedrela fissilis, Enterolobium contortisiliquum, Handroanthus impetiginosus, and Piptadenia gonoacantha. The seeds were collected in the region of Lavras, MG, and subjected to desiccation experiments individually for each species. Imbibition curve was created for each species by measuring seed weight at regular intervals under germination conditions. Based on this information, the seeds were allowed to imbibe for a time inferred from the imbibition curve, and then allowed to dry until reaching the initial water content measured before the imbibition begun. Then, the seeds were rehydrated, and those that developed into normal seedlings were considered desiccation-tolerant. The loss of seed desiccation tolerance followed a specific pattern in each studied species, but none of the species was tolerant to desiccation after radicle protrusion. A drastic decrease in desiccation tolerance was observed in P. gonoacantha seeds at the beginning of the germination process. Under the conditions implemented in this study, the loss of desiccation tolerance in all species started at the beginning of the germination process. These results have implications in both theoretical studies (seed priming) and the practice (in seedling production).

title: PREVENTIVE AND CURATIVE CONTROL OF Oidium eucalypti IN Eucalyptus benthamii CLONAL SEEDLINGS

description: ABSTRACT One of the main diseases occurring in clonal nurseries of Eucalyptus spp. is powdery mildew caused by the fungus Oidium eucalypti. This work evaluated the efficiency of biological products based on Trichoderma spp. and Bacillus spp. applied as preventive and curative treatments for the control of Oidium eucalypti in clonal seedlings of E. benthamii Maiden et Cambage. Treatments were: Trichoderma harzianum (THP), T. atroviride (TAI), T. harzianum (THE), Trichoderma spp. (TTA), Bacillus spp. (BNE), Sulfur (KUM), Difenoconazol (SCO) and distilled water (AD). Treatments were applied preventively by spraying seven days before inoculation of the pathogen, and in curatively, ten days after inoculation. Weekly evaluations of the incidence and severity of the disease were done. The analyzed variables were: Disease Index (ID) and Incidence (I), calculating the area under the disease curve (AUDPC) for each treatment. The results pointed BNE (Bacillus spp.) and TAI (isolate T. atroviride) as effective preventive treatments and BNE (Bacillus spp.), applied curatively for the control of O. eucalypti in E. benthamii seedlings, proving that treatments based on biological products may be effective for controlling eucalyptus powdery mildew in clonal nurseries.

title: Re-presentation and documentation of installation art in three Brazilian museums

description: ABSTRACT The present paper aimed to understand how three different Brazilian museums, concerned with the collection of contemporary art, manage the documentation and re-exhibition of installations art contained in the collections. To this end, we chose to initially delineate what is understood as an artistic “installation” within the museological dynamics and to problematize the question of how art historians and professionals dedicated to the management of museum collections are facing a particular challenge: the reinstallation of the premises and necessary to instruct it. Analyzes of documents, consultations with managers, artists and works guided our methodology. The research found the dependence of museums on documentation coming from artists, the heterogeneity of this documentation and the absence of documents necessary for re-presentation of the works.

title: I’ve got Toothache, I need Antibiotics: a UK Perspective on Rational Antibiotic Prescribing by Dentists

description: Abstract Antibiotics do not cure toothache. This headline message of the United Kingdom’s (UK) Dental Antimicrobial Stewardship (AMS) toolkit’s posters and leaflets is aimed at patients; clinicians are expected to know this already. Evidence based clinical guidelines exist to set clear standards for good clinical practice yet there are barriers to compliance. The national AMS audit tool is designed for clinicians to review their management of acute dental conditions, including but not limited to the prescription of antibiotics. In this article we aim to help dental teams protect their patients and themselves from adverse events related to antibiotic prescription. It explores the emergent problem of Clostridium difficile, antibiotic resistance and severe sepsis, and considers some of the barriers, which clinicians have suggested, contribute to the unjustified prescription of antibiotics. Dentists must weigh the risks against the benefits before prescribing any antibiotic.

title: Desmids (Zygnematophyceae) from the littoral zone of an urban artificial lake: taxonomic aspects and geographical distribution

description: Abstract Aim: The aim of this study was to assess the taxonomic aspects and geographical distribution of the periphytic desmids from two different substrates in the littoral zone of an urban artificial lake. Methods Samples of epiphytic and epilithic desmids were collected by grass and rock scraping, respectively, in two stations in the Cascavel municipal lake, Paraná, during April 2015, and March 2016 and 2017. In the laboratory, the taxa obtained from the samples were photographed and their morphometric characteristics recorded. The species composition of the desmid was characterized, and the frequency of occurrence as well as the geographic distribution of each taxon in the Paraná State were recorded. Results We identified 35 taxa, distributed in 10 genera. The most representative were Closterium Nitzsch ex Ralfs and Cosmarium Corda ex Ralfs. A high occurrence of sporadic taxa (60%) was observed and among the recorded taxa, the most frequent were Cosmarium pseudoconnatum Nordstedt var. pseudoconnatum and Desmidium grevillei (Kützing ex Ralfs) De Bary. Nine taxa were exclusive to the epilithic substrate and only Netrium digitus (Ralfs) Itzigsohn & Rothe var. digitus was exclusive to the epiphytic substrate, while the remaining 25 taxa occurred in both substrates. Seven taxa are new records for the Paraná State. Conclusion Although our results are of qualitative nature, they provide baseline data on the biogeographic distribution of taxa, which are crucial for future taxonomic and ecological studies that might contribute to the preservation of the biodiversity.

title: How Long does it Take to Examine Young Children with the Caries ICDAS System and how do they Respond?

description: Abstract A caries-epidemiological study using the ICDASepi-merged system was conducted in Colombian young children. This study aimed at associating the time needed for the clinical examination of caries and caries risk in 1 to 5-year-old children according to age and caries risk, and to assess behavior and child pain self-perception during examination according to age. After IRB approval and given parents/caregivers’ informed consent, seven trained examiners assessed 1 to 5-year olds in kindergartens under local field conditions. ICDASepi-merged caries experience (depiMEmf) was assessed as follows: Initial-depi (ICDAS 1/2 without air-drying); Moderate-dM (ICDAS 3,4); Extensive-dE (ICDAS 5,6) lesions; due-to-caries fillings-f and missing-m surfaces/teeth. Caries risk was assessed with Cariogram®. Child’s behavior (Frankl-Behavior-Rating-Scale) and self-perceived pain (Visual-Analogue-Scale-of-Faces) during examination were evaluated. Clinical examination time was recorded with a stopwatch. A total of 592 children participated (1-yr.: n=31; 2-yrs.: n=96; 3-yrs.: n=155; 4-yrs.: n=209, 5-yrs.: n=101). The depiMEmfs prevalence was of 79.9% and the mean 8.4±10.4. Most were high-caries-risk children (68.9%). The majority (58.9%) showed ≥ positive-behavior and ≤ light-pain self-perception (88.4%). Mean clinical examination time was around 3.5 minutes (216.9±133.9 seconds). For 5-yr. olds it corresponded to 4 minutes (240.4±145.0 seconds) vs. 2 minutes (122.8±80.1 seconds) for 1-yr. olds (Kruskal-Wallis; p=0.00). For high- and low-caries risk children it was around 4.3 minutes (255.7±118.5 seconds) and 3.3 minutes (201.3±129.4 seconds), respectively (ANOVA; p=0.01). This study demonstrates using the ICDAS system in young children is feasible, taking less than 4 minutes for the clinical examination without children behavior/pain self-perception issues.
