Worldwide genetic variation at the 3´-UTR region of the LDLR gene : possible influence of natural selection
(2005) [Artículo de periódico]The low density lipoprotein receptor gene (LDLR) contains many Alu insertions, and is especially Alu-rich at its 3 -untranslated region (3 -UTR). Previous studies suggested that the LDLR 3 -UTR could regulate gene expression ... -
Worldwide trends in body-mass index, underweight, overweight, and obesity from 1975 to 2016 : a pooled analysis of 2416 population-based measurement studies in 128.9 million children, adolescents, and adults
(2017) [Artículo de periódico]Background Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) ... -
Xenoestrogênios : o exemplo do bisfenol-a
(2000) [Artículo de periódico]Evidências acumuladas indicam que a saúde dos seres humanos, animais e espécies selvagens pode sofrer conseqüências adversas da exposição a produtos químicos presentes no meio ambiente e que interagem com o sistema endócrino, ... -
X-linked adrenoleukodystrophy : clinical and laboratory findings in 15 brazilian patients
(2000) [Artículo de periódico]Adrenoleucodistrofia (X-ALD) é uma desordem peroxissomal com padrão de herança ligada ao X, fenotipicamente heterogênea, caracterizada por uma progressiva desmielinização da substância branca do sistema nervoso central e ... -
Y-chromosome biallelic polymorphisms and native american population structure
(2002) [Artículo 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) [Artículo 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) [Artículo 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) [Artículo 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) [Artículo 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) [Artículo 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) [Artículo 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) [Artículo 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) [Artículo 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 ... -
Zygoparity in Characidae: the first case of internal fertilization in the teleost cohort Otomorpha
(2020) [Artículo 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 ...
