1. Application of Cervical Vestibular-Evoked Myogenic Potentials in Adults with Moderate to Profound Sensorineural Hearing Loss: A Preliminary Study
Abstract Introduction The cochlea and the vestibular receptors are closely related in terms of anatomy and phylogeny. Patients with moderate to profound sensorineural hearing loss (MPSHL) should have their vestibular organ functions tested. Objective To evaluate the incidence of vestibular abnormalities in patients with MPSHL and to study the correlation

2. Spatial distribution and egg production in squat lobsters (Decapoda: Munididae, Munidopsidae) from the collection of the Museu de Zoologia of the Universidade de São Paulo, Brazil
ABSTRACT: Spatial distribution and egg production of squat lobsters is examined from specimens deposited in the collection of the Museu de Zoologia of the Universidade de São Paulo (MZUSP), Brazil. A total of 1,346 specimens of squat lobsters were analyzed, out of which 169 were ovigerous females. Ovigerous females contained ten species of Munididae (n = 16

3. Contribution of dark septate fungi to the nutrient uptake and growth of rice plants
ABSTRACT The use of dark septate fungi (DSE) to promote plant growth can be beneficial to agriculture, and these organisms are important allies in the search for sustainable agriculture practices. This study investigates the contribution of dark septate fungi to the absorption of nutrients by rice plants and their ensuing growth. Four dark septate fungi isol

4. Molecular evolution and functional divergence of alcohol dehydrogenases in animals, fungi and plants
Abstract Alcohol dehydrogenases belong to the large superfamily of medium-chain dehydrogenases/reductases, which occur throughout the biological world and are involved with many important metabolic routes. We considered the phylogeny of 190 ADH sequences of animals, fungi, and plants. Non-class III Caenorhabditis elegans ADHs were seen closely related to tet

5. NUEVA ESPECIE DE RANA BROMELÍCOLA DEL GÉNERO PRISTIMANTIS (AMPHIBIA: CRAUGASTORIDAE), MESETA DE LA CORDILLERA DEL CÓNDOR, ECUADOR
ABSTRACT We describe a small frog of the genus Pristimantis inhabiting bromeliads (snout-vent length 20.3-23.3 mm in females, 16.1-17.4 mm in males), from a remote sandstone plateau of the Cordillera del Condor, in southeastern Ecuador, with an altitudinal range of 2,045-2,860 m. A phylogeny based on sequences of DNA (mitochondrial and nuclear genes) support

6. TRIAGEM METABÓLICA POR PKS E NRPS EM ACTINOBACTÉRIAS ENDOFÍTICAS DE Citrus reticulata
Polyketides and non-ribosomal peptides are natural products widely found in bacteria, fungi and plants. The biological activities associated with these metabolites have attracted special attention in biopharmaceutical studies. Polyketide synthases act similarly to fatty acids synthetases and the whole multi-enzymatic set coordinating precursor and extending

7. Analysis of the ergosterol biosynthesis pathway cloning, molecular characterization and phylogeny of lanosterol 14α-demethylase (ERG11) gene of Moniliophthora perniciosa
The phytopathogenic fungus Moniliophthora perniciosa (Stahel) Aime & Philips-Mora, causal agent of witches' broom disease of cocoa, causes countless damage to cocoa production in Brazil. Molecular studies have attempted to identify genes that play important roles in fungal survival and virulence. In this study, sequences deposited in the M. perniciosa Genome

8. Description of microsporidia in simulids: molecular and morphological characterization of microsporidia in the larvae of Simulium pertinax Kollar (Diptera: Simuliidae)
IntroductionMicrosporidia constitute the most common black fly pathogens, although the species' diversity, seasonal occurrence and transmission mechanisms remain poorly understood. Infections by this agent are often chronic and non-lethal, but they can cause reduced fecundity and decreased longevity. The objective of this study was to identify microsporidia

9. Comunidades de hidrozoários (Cnidaria) estuarinos do sudeste e sul do Brasil / Communities of stuarine hydrozoans (Cnidaria) from south and southeast of Brazil
The majority of the hydrozoans is marine, but they are also often recorded in estuaries. This environment is considered one of the most important in number of biological invasions. The Brazilian brackish hydrozoan fauna is practically unknown, except for some scattered records. The goals of this study are (1) to survey the planktonic and benthic hydrozoans f

10. Caracterização in silico e análise da expressão de genes das rotas de biossíntese e sinalização do etileno em frutos de diferentes cultivares de café (coffea arabica) / In silico characterization and expression analysis of genes of the ethylene biosynthesis and signaling pathways in fruits of different coffee (Coffea arabica) cultivars
Coffee is the second most commercialized product in the world posing as an important source of income and jobs in several countries, mainly in developing countries such as Brazil, the largest producer and the second largest consumer of coffee in the world. Coffee quality, among other factors, is directly associated to the fruit ripening stage at harvest time

11. Caracterização biológica e molecular de recombinantes naturais de HIV-1. / Biological and molecular characterization of HIV-1 natural recombinants.
Recombination during reverse transcription is an important factor promoting HIV-1 diversity and adaptive change, allowing advantageous mutations arising on different genomes to undergo linkage in the same progeny recombinant genome more frequently than what would be expected under random mutation alone. In Brazil, several recombinant viruses were reported, a
