Relatedness reveals a strong road effect on female bat genetic connectivity
Medinas, Denis; Ribeiro, Vera; Barbosa, Soraia; Valerio, Francesco; Marques, João Tiago; Rebelo, Hugo; Paupério, Joana; Santos, Sara MariaThe effective management of species with small and fragmented populations requires an in-depth understanding of how the effects of human-induced habitat disturbance shape the structure and gene flow at fine spatial scales. Identification of putative environmental barriers that affect individual exchange among subpopulations is imperative to prevent extinction risks. Here, we investigated how landscape affects t...

Hit the road Jane! Roads decrease the relatedness for females lesser horseshoe ...
Medinas, Denis; Marques, João Tiago; Ribeiro, Vera; Rebelo, Hugo; Barbosa, Soraia; Valerio, Francesco; Santos, Sara; Mira, AntónioThe understanding of how human-induced habitat disturbance shapes the contemporary population structure and gene flow at a fine-spatial scale is key for adequate management of species with small and fragmented populations and with limited dispersal abilities. To date, there are few studies focusing on how barriers (e.g. roads, habitat fragmentation) might influence gene flow at fine scales. Roads are known for ...
Repetitive Negative Thinking and Sexual Functioning in Portuguese Men and Women...
Peixoto, Maria Manuela; Ribeiro, VeraPublish at: International Journal of Sexual Health, Volume 34, Issue 4; Repetitive negative thinking (RNT) is a transdiagnostic process involved in the development and maintenance of emotional disorders that negatively affect sexual functioning. However, empirical evidence for the role of RNT on sexual functioning is still lacking. The current study aimed to investigate the role of RNT on sexual functioning in ...
Pharmacogenetic analysis of inter-ethnic variability in the uptake transporter ...
Nega, Mulata Haile; Berhe, Derbew F.; Ribeiro, VeraBackground Statin-induced myopathy is reported to be associated with the solute carrier organic anion transporter family member 1B1 gene single nucleotide polymorphism, c.521 T > C. There is no epidemiologic data on this gene polymorphism in several countries. Therefore, this study aimed at assessing the genotype and allele frequencies of the gene variant in three countries. Methods This study involved healthy ...
Endometrial cancer staging: Is there value in ADC?
Moreira, Ana; Ribeiro, Vera; Aringhieri, Giacomo; Fanni, Salvatore; Tumminello, Lorenzo; Faggioni, Lorenzo; Cioni, Dania; Neri, EmanuelePurpose: To assess the ability of apparent diffusion coefficient (ADC) measurements in predicting the histological grade of endometrial cancer. A secondary goal was to assess the agreement between MRI and surgical staging as an accurate measurement. Methods: Patients with endometrial cancers diagnosed between 2018-2020 and having received both MRI and surgical staging were retrospectively enrolled. Patients wer...
Nusinersen: Single-Centre Real-Life Experience in Type 1 Spinal Muscular Atrophy
Lomba, Andreia; A. Ribeiro, Joana; Araújo, Henriqueta; Ribeiro, Vera; Madureira, Núria; Palavra, Filipe; Costa, Carmen; Fineza, IsabelIntroduction: Nusinersen, an antisense oligonucleotide designed to treat spinal muscular atrophy, led to substantial motor milestone achievements in clinical trials. The aim of this study was to report the clinical outcome of children diagnosed with spinal muscular atrophy type 1 treated with nusinersen in a tertiary centre. Methods: Retrospective study of type 1 spinal muscular atrophy patients treated with nu...
Biodiesel Production Systems: Operation, Process Control and Troubleshooting
Caetano, Nídia; Ribeiro, Vera; Ribeiro, Leonardo; Baptista, Andresa; Monteiro, JoaquimBiodiesel is a renewable fuel, produced from waste cooking oils, animal fats, vegetable and algae oils. Its use is intended to replace diesel in conventional diesel engines, causing lower polluting emissions. To produce biodiesel, certain details must be carefully considered, namely feedstock composition, reaction parameters, process conditions, process equipment, purification processes, analysis of biodiesel p...
Road effects on bat activity depend on surrounding habitat type
Medinas, Denis; Ribeiro, Vera; Marques, João Tiago; Silva, Bruno; Barbosa, Ana Márcia; Rebelo, Hugo; Mira, AntónioThe effects of roads on bats are still a poorly documented issue.Most of the available research focuses on large and hightraffic highways, while low-medium-traffic roads are often assumed to have negligible impacts. However, small roads are ubiquitous in landscapes around the world.We examined the effects of these roads, aswell as habitat types, on the activity of three bat guilds (short-, mid- and long-range e...
Job Shop Flow Time Prediction using Neural Networks
Silva, Cristovão; Ribeiro, Vera; Coelho, Pedro; Magalhães, Vanessa; Neto, PedroIn this paper we investigate the use of Artificial Neural Networks (ANN) for flow time prediction and, consequently, to estimate due dates (DD) in a hypothetical dynamic job-shop. The effectiveness of the proposed ANN based DD assignment model is evaluated comparing it performance with the performance of two dynamic DD assignment rules proposed in the literature: Dynamic Total Work Content, and Dynamic Processi...
