Does inter-organellar proteostasis impact yeast quality and performance during beer fermentation?
(2020) [Artigo de periódico]During beer production, yeast generate ethanol that is exported to the extracellular environment where it accumulates. Depending on the initial carbohydrate concentration in the wort, the amount of yeast biomass inoculated, ... -
Does pregabalin improve sleep disorders in fibromyalgia?
(2018) [Artigo de periódico]BACKGROUND AND OBJECTIVES: Fibromyalgia is a chronic generalized pain syndrome accompanied by somatic symptoms, mainly represented by sleep disorders. Pregabalin is the main agent among pharmacological treatments. CONTENTS: ... -
Does variation in genome sizes reflect adaptive or neutral processes? New clues from Passiflora
(2011) [Artigo de periódico]One of the long-standing paradoxes in genomic evolution is the observation that much of the genome is composed of repetitive DNA which has been typically regarded as superfluous to the function of the genome in generating ... -
Dolphin interactions with the mullet artisanal fishing on southern Brazil : a qualitative and quantitative approach
(1998) [Artigo de periódico]A detailed analysis of the interactions between Tursiops /runco/us (Montagu, 1821) and the artisanal fishing of mullets (MugU spp.) is presented at two localities in the south of Brazil: Laguna (Santa Catarina) and ... -
Draft genome sequence of a GES-5-producing Serratia marcescens isolated in southern Brazil
(2017) [Artigo de periódico]Serratia marcescens is a Gram-negative rod intrinsically resistant to polymyxins and usually associated with wound, respiratory and urinary tract infections. The whole genome of the first GES-5-producing S. marcescens ... -
Draft genome sequence of Bacillus sp. strain UFRGS-B20, a hydrocarbon degrader
(2018) [Artigo de periódico]Bacillus sp. strain UFRGS-B20 was isolated in 2012 from Brazilian landfarming soil contaminated with petrochemical oily sludge. This strain was subjected to hydrocarbon biodegradation tests, showing degradation rates of ... -
Draft genome sequence of the Daphnia pathogen Octosporea bayeri : insights into the gene content of a large microsporidian genome and a model for host-parasite interactions
(2009) [Artigo de periódico]Background: The highly compacted 2.9-Mb genome of Encephalitozoon cuniculi placed the microsporidia in the spotlight, encoding a mere 2,000 proteins and a highly reduced suite of biochemical pathways. This extreme level ... -
DRD4 rare variants in attention-deficit/hyperactivity disorder (ADHD) : further evidence from a birth cohort study
(2013) [Artigo de periódico]The dopamine receptor D4 (DRD4) is one of the most studied candidate genes for Attention-Deficit/Hyperactivity Disorder (ADHD). An excess of rare variants and non-synonymous mutations in the VNTR region of 7R allele in ... -
DREB genes from common bean (Phaseolus vulgaris L.) show broad to specific abiotic stress responses and distinct levels of nucleotide diversity
(2019) [Artigo de periódico]We analyzed the nucleotide variability and the expression profile of DREB genes from common bean, a crop of high economic and nutritional value throughout the world but constantly affected by abiotic stresses in cultivation ... -
Drivers of bromeliad leaf and floral bract variation across a latitudinal gradient in the Atlantic Forest
(2020) [Artigo de periódico]Aim: Understanding the complex interaction and relative contributions of factors involved in species and trait diversification is crucial to gain insights into the evolution of Neotropical biodiversity. Here, we investigated ... -
Drivers of nest survival in the Tawny-bellied Seedeater Sporophila hypoxantha (Aves: Thraupidae) : time-specific factors are more related to success than ecological variables
(2021) [Artigo de periódico]Tawny-bellied Seedeater (Sporophila hypoxantha) is an endangered (in Brazil) grassland dependent species, whose breeding success remains poorly known hampering conservation measures on its breeding grounds. Here we analyze ... -
Drosophila relics hobo and hobo-MITEs transposons as raw material for new regulatory networks
(2018) [Artigo de periódico]Hypermutable strains of Drosophila simulans have been studied for 20 years. Several mutants were isolated and characterized, some of which had phenotypes associated with alteration in development; for example, showing ... -
