Genetic relatedness, virulence factors and antimicrobial resistance of C. difficile strains from hospitalized patients in a multicentric study in Brazil
(2020) [Artigo de periódico]Background: Clostridium (Clostridioides) difficile infection (CDI) is recognized worldwide as a public health concern, related mainly with hypervirulent strains. In Brazil there are few studies about molecular epidemiology ... -
Genetics and human rights. Two histories : restoring genetic identify after forced disappearance and identify suppression in Argentina and after compulsory isolation for leprosy in Brazil
(2014) [Artigo de periódico]Over the past three decades, there has been an accelerated development of genetic technology, leading to its use in human genetic identification for many purposes. Additionally, it has been made explicit that identity is ... -
Genetics, evolution and conservation of Bromeliaceae
(2012) [Artigo de periódico]Bromeliaceae is a morphologically distinctive and ecologically diverse family originating in the New World. Three centers of diversity, 58 genera, and about 3,140 bromeliad species are currently recognized. We compiled all ... -
Genetic signatures of parental contribution in black and white populations in Brazil
(2009) [Artigo de periódico]Two hundred and three individuals classified as white were tested for 11 single nucleotide polymorphisms plus two insertion/deletions in their Y-chromosomes. A subset of these individuals (n = 172) was also screened for ... -
Genetics of homocysteine metabolism and associated disorders
(2010) [Artigo de periódico]Homocysteine is a sulfur-containing amino acid derived from the metabolism of methionine, an essential amino acid, and is metabolized by one of two pathways: remethylation or transsulfuration. Abnormalities of these pathways ... -
Genetics of Parkinson’s disease in Brazil : systematic review of monogenic forms
(2021) [Artigo de periódico]Background: Increasing numbers of mutations causing monogenic forms of Parkinson's disease (PD) have been described, mostly among patients in Europe and North America. Since genetic architecture varies between different ... -
Genetics, surnames, grandparents' nationalities, and ethnic admixture in southern Brazil - do the patterns of variation coincide?
(1999) [Artigo de periódico]Uma amostra de 2.708 descendentes de europeus que vivem no Rio Grande do Sul, o qual foi subdividido em sete mesorregiões, e de 226 pessoas da mesma procedência provenientes de Santa Catarina foi estudada quanto a 17 ... -
Genetic structure and conservation of mountain lions in the south-brazilian atlantic rain forest
(2012) [Artigo de periódico]The Brazilian Atlantic Rain Forest, one of the most endangered ecosystems worldwide, is also among the most important hotspots as regards biodiversity. Through intensive logging, the initial area has been reduced to around ... -
Genetic structure of sigmodontine rodents (Cricetidae) along an altitudinal gradient of the Atlantic Rain Forest in southern Brazil
(2009) [Artigo de periódico]The population genetic structure of two sympatric species of sigmodontine rodents (Oligoryzomys nigripes and Euryoryzomys russatus) was examined for mitochondrial DNA (mtDNA) sequence haplotypes of the control region. ... -
Genetic susceptibility to drug teratogenicity: a systematic literature review
(2021) [Artigo de periódico]Since the 1960s, drugs have been known to cause teratogenic effects in humans. Such teratogenicity has been postulated to be influenced by genetics. The aim of this review was to provide an overview of the current knowledge ... -
Genetic variability in common wheat germplasm based on coefficients of parentage
(2002) [Artigo de periódico]The characterization of genetic variability and an estimate of the genetic relationship among varieties are essential to any breeding program, because artificial crosses among less similar parents allow a larger segregation ... -
Genetic variability in maize and teosinte populations estimated by microsatellites markers
(2011) [Artigo de periódico]Wild species are important sources of genetic variability and may be exploited by breeding programs. Crosses between teosinte and maize occur freely and teosinte serves as genetic source of agronomic traits for introduction ... -
Genetic variability of Bipolaris sorokiniana isolates using URP-PCR
(2014) [Artigo de periódico]Spot blotch disease, caused by Bipolaris sorokiniana, is one of the major diseases of wheat and is responsible for large losses of wheat crops worldwide. We used polymerase chain reaction (PCR) with universal rice primers ... -
Genetic variant in vitamin D-binding protein is associated with metabolic syndrome and lower 25-hydroxyvitamin D levels in polycystic ovary syndrome : a cross-sectional study
(2017) [Artigo de periódico]Vitamin D deficiency has been related to metabolic syndrome (MetS) in polycystic ovary syndrome (PCOS). The vitamin D-binding protein (DBP) is the main protein involved in vitamin D transport. Two single-nucleotide ... -
Genetic variation among major human geographic groups supports a peculiar evolutionary trend in PAX9
(2011) [Artigo de periódico]A total of 172 persons from nine South Amerindian, three African and one Eskimo populations were studied in relation to the Paired box gene 9 (PAX9) exon 3 (138 base pairs) as well as its 59and 39flanking intronic segments ... -
Genetic variation and population structure in native americans
(2008) [Artigo de periódico]We examined genetic diversity and population structure in the American landmass using 678 autosomal microsatellite markers genotyped in 422 individuals representing 24 Native American populations sampled from North, Central, ... -

Genetic variation of the bronze locus (MC1R) in turkeys from Southern Brazil
(2017) [Artigo de periódico]Domestic turkeys present several color phenotypes controlled by at least five genetic loci, but only one of these has been identified precisely: the bronze locus, which turned out to be the melanocortin-1 receptor (MC1R) ...
