Y-chromosome biallelic polymorphisms and native american population structure
(2002) [Artigo de periódico]It has been proposed that women had a higher migration rate than men throughout human evolutionary history. However, in a recent study of South American natives using mtDNA restriction fragment polymorphisms and Y-chromosome ... -
Yellow fever virus maintained by Sabethes mosquitoes during the dry season in Cerrado, a Semiarid Region of Brazil, in 2021
(2023) [Artigo de periódico]In recent decades, waves of yellow fever virus (YFV) from the Amazon Rainforest have spread and caused outbreaks in other regions of Brazil, including the Cerrado, a savannah-like biome through which YFV usually moves ... -
Zap1 regulates zinc homeostasis and modulates virulence in Cryptococcus gattii
(2012) [Artigo de periódico]Zinc homeostasis is essential for fungal growth, as this metal is a critical structural component of several proteins, including transcription factors. The fungal pathogen Cryptococcus gattii obtains zinc from the stringent ... -
Zika Brazilian Cohorts (ZBC) Consortium: protocol for an individual participant data meta-analysis of congenital Zika syndrome after maternal exposure during pregnancy
(2021) [Artigo de periódico]Despite great advances in our knowledge of the consequences of Zika virus to human health, many questions remain unanswered, and results are often inconsistent. The small sample size of individual studies has limited ... -
Zika virus envelope domain III recombinant protein delivered with saponin-based nanoadjuvant from Quillaja brasiliensis enhances anti-zika immune responses, including neutralizing antibodies and splenocyte proliferation
(2021) [Artigo de periódico]Nanoadjuvants that combine immunostimulatory properties and delivery systems reportedly bestow major improvements on the efficacy of recombinant, protein-based vaccines. Among these, self-assembled micellar formulations ... -
Zika virus exposure affects neuron-glia communication in the hippocampal slices of adult rats
(2020) [Artigo de periódico]Zika virus (ZIKV) infection during pregnancy was associated with microcephaly in neonates, but clinical and experimental evidence indicate that ZIKV also causes neurological complications in adults. However, the changes ... -
Zika virus infection leads to mitochondrial failure, oxidative stress and DNA damage in human iPSC-derived astrocytes
(2020) [Artigo de periódico]Zika virus (ZIKV) has been extensively studied since it was linked to congenital malformations, and recent research has revealed that astrocytes are targets of ZIKV. However, the consequences of ZIKV infection, especially ... -
Zinc-induced facilitator-like family in plants:lineage-specific expansion in monocotyledons and conserved genomic and expression features among rice(Oryza sativa) paralogs
(2011) [Artigo de periódico]Background: Duplications are very common in the evolution of plant genomes, explaining the high number of members in plant gene families. New genes born after duplication can undergo pseudogenization, neofunctionalization ... -
Zoonotic spillover: understanding basic aspects for better prevention
(2021) [Artigo de periódico]The transmission of pathogens from wild animals to humans is called “zoonotic spillover”. Most human infectious diseases (60-75%) are derived from pathogens that originally circulated in non-human animal species. This ... -
Zooplankton and water quality of lakes of the northern coast of Rio Grande do Sul State, Brazil
(2005) [Artigo de periódico]The indicator properties of zooplankton assemblages were evaluated along the environmental gradient of water quality caused by organic effluent discharge in the following lakes: Marcelino, Peixoto, Pinguela, Palmital, ... -
Zygoparity in Characidae: the first case of internal fertilization in the teleost cohort Otomorpha
(2020) [Artigo de periódico]Most teleosts are externally fertilizing, with internal fertilization occurring as a relatively rare event. Until now, Euteleosteomorpha is the only teleost cohort known to undergo internal fertilization. In the teleost ...
