Forgetting of long-term memory requires activation of NMDA receptors, L-type voltage-dependent Ca2+ channels, and calcineurin
(2016) [Artículo de periódico]In the past decades, the cellular and molecular mechanisms underlying memory consolidation, reconsolidation, and extinction have been well characterized. However, the neurobiological underpinnings of forgetting processes ... -
Formações florestais do Parque Estadual de Itapuã, Rio Grande do Sul : caracterização do habitat do bugio-ruivo (Alouatta clamitans CABRERA, 1940)
(2009) [Artículo de periódico]Este estudo teve como objetivo (i) caracterizar as diferentes formações florestais do Morro do Campista, no Parque Estadual de Itapuã, Viamão, RS, e (ii) analisar aspectos relacionados à composição e estrutura dessas ... -
Fos expression in the prefrontal cortex and mesencephalic dorsal raphe nucleus in lactating rats after social instigation
(2013) [Artículo de periódico]Females are often less aggressive than males, but they exhibit high levels of agonistic behavior against an intruder in the area of the nest during lactation. This behavior is referred to as maternal aggression. In rats, ... -
FOXP in tetrapoda : intrinsically disordered regions, short linear motifs and their evolutionary significance
(2017) [Artículo de periódico]The FOXP subfamily is probably the most extensively characterized subfamily of the forkhead superfamily, playing important roles in development and homeostasis in vertebrates. Intrinsically disorder protein regions (IDRs) ... -
FragSAD: a database of diversity and species abundance distributions from habitat fragments

A framework for understanding the relationship between descending pain modulation, motor corticospinal and neuroplasticity regulation systems in chronic myofascial pain
(2016) [Artículo de periódico]Myofascial pain syndrome (MPS) is a leading cause of chronic musculoskeletal pain. However, its neurobiological mechanisms are not entirely elucidated. Given the complex interaction between the networks involved in pain ... -
Free carnitine and branched chain amino acids are not good biomarkers in Huntington’s disease
(2020) [Artículo de periódico]Background: Huntington’s disease (HD), caused by an expanded CAG repeat at HTT, has no treatment, and biomarkers are needed for future clinical trials. Objective: The objective of this study was to verify if free carnitine ... -
Frequency of CCR5delta32 in brazilian populations
(2006) [Artículo de periódico]A sample of 103 randomly chosen healthy individuals from Alegrete, RS, Brazil, was tested for the CCR5Δ32 allele, which is known to influence susceptibility to HIV-1 infection. The CCR5Δ32 allele was identified by PCR ... -
Frequency of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPRs) in non-clinical Enterococcus faecalis and Enterococcus faecium strains
(2019) [Artículo de periódico]The fidelity of the genomes is defended by mechanism known as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) systems. Three Type II CRISPR systems (CRISPR1-cas, CRISPR2 and CRISPR3-cas) have been ... -
From abortion-inducing medications to Zika Virus Syndrome : 27 years experience of the First Teratogen Information Service in Latin America
(2019) [Artículo de periódico]In 1990, the first Teratogen Information Service in Brazil (SIAT) was implemented in the Medical Genetics Service at Hospital de Clinicas de Porto Alegre. SIAT is a free-to-use information service both to health professionals ... -
From rumors to genetic isolates
(2014) [Artículo de periódico]Here we propose a registration process for population genetic isolates, usually geographic clusters of genetic disorders, based on the systematic search of rumors, defined as any type of account regardless of its reliability. ... -
From the farm to the lab : how chicken embryos contribute to the field of teratology
(2021) [Artículo de periódico]Congenital anomalies and its causes, particularly, by external factors are the aim of the field called teratology. The external factors studied by teratology are known as teratogens and can be biological or environmental ... -
Fruit-feeding butterflies guide of subtropical Atlantic Forest and Araucaria Moist Forest in State of Rio Grande do Sul, Brazil.
(2011) [Artículo de periódico]This study presents a compilation of fruit-feeding butterflies species for Rio Grande do Sul Atlantic Forest aiming to be a tool for identification of these lepidopterans from two phytophysiognomies of this biome. Samples ... -
Fruits and vegetables intake and characteristics associated among adolescents from Southern Brazil
(2012) [Artículo de periódico]Background: Increased body weight has been associated with an unhealthy diet, low consumption of fruits and vegetables. Our objective was to investigate whether adolescents had low intake of fruits and vegetables, and ... -
Functional abilities of cultivable plant growth promoting bacteria associated with wheat (Triticum aestivum L.) crops
(2016) [Artículo de periódico]In the pursuit of sustainable agriculture, bioinoculants usage as providers of a crop’s needs is a method to limit environmental damage. In this study, a collection of cultivable putative plant growth promoting (PGP) ... -
Functional cognitive disorder presents high frequency and distinct clinical profile in patients with low education
(2022) [Artículo de periódico]Introduction: Functional Cognitive Disorder (FCD) is a non-degenerative, common cause of memory complaint in patients with high educational levels. FCD has been insufficiently described in individuals with low education. ... -
Functional patterns of tree communities in natural Araucaria forests and old monoculture conifer plantations
(2019) [Artículo de periódico]A functional perspective of tree communities is helpful for understanding forest dynamics, especially vegetation recovery after other land uses. Knowledge about ecological filters and survival strategies of trees are also ... -
Functional polymorphisms in the p53 pathway genes on the genetic susceptibility to zika virus teratogenesis
(2021) [Artículo de periódico]Congenital Zika Syndrome (CZS) occurs in up to 42% of individuals exposed to ZIKV prenatally. Deregulation in gene expression and protein levels of components of the p53 signaling pathway, such as p53 and MDM2, due to ZIKV ... -
Functional recovery caused by human adipose tissue mesenchymal stem cell-derived extracellular vesicles administered 24 h after stroke in rats
(2021) [Artículo de periódico]Ischemic stroke is a major cause of death and disability, intensely demanding innovative and accessible therapeutic strategies. Approaches presenting a prolonged period for therapeutic intervention and new treatment ... -
Functional redundancy of non-volant small mammals increases in human-modified habitats
(2021) [Artículo de periódico]Aim: Humans are rapidly altering natural habitats across much of the globe. Here we compared 264 globally distributed communities in natural and human-modified habitats to detect changes in community richness and functional ...
