Following the trail: factors underlying the sudden expansion of the Egyptian mongoose (Herpestes ichneumon) in Portugal
(2015) [Journal article]Species range-limits are influenced by a combination of several factors. In our study we aimed to unveil the drivers underlying the expansion of the Egyptian mongoose in Portugal, a carnivore that was confined to southern ... -
Follow-up of pre-motor symptoms of Parkinson’s disease in adult patients with Gaucher disease type 1 and analysis of their lysosomal enzyme profiles in the CSF
(2023) [Journal article]Background: Parkinson’s disease (PD) is the second most common neurodegenerative disease worldwide. Its classic motor symptoms may be preceded by non-motor symptoms (NMS). Population studies have identified GBA variants ... -
Foraging behavioral of Phylloscartes ventralis (Aves, Tyrannidae) in native and planted forests of southern Brazil
(2014) [Journal article]Few studies have related the effects of silviculture practices to the behavior of bird species in the Neotropics. The present study examined the foraging behavior of Phylloscartes ventralis (Temminck, 1824) in a native ... -
Foraging behaviour of brazilian riverine and coastal fishers : how much is explained by the optimal foraging theory?
(2011) [Journal article]Optimal Foraging Theory (OFT) is here applied to analyse the foraging behaviour of Brazilian artisanal fi shers of the Atlantic coast (Itacuruçá and São Paulo Bagre villages) and of the inland Amazonian region (Jarauá and ... -
Forgetting of long-term memory requires activation of NMDA receptors, L-type voltage-dependent Ca2+ channels, and calcineurin
(2016) [Journal article]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 ... -

(2009) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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 ... -
