Temporal-parietal fascia and polydioxanone plates (PDS), the solution for septa...
Martins Pinto, Catarina; Matos, Ricardo; Moreira Silva, Francisco; Martins, Margarida; Pedro Mota, Clara; Santos, Mariana; Morgado, DuarteIntroduction: Septal perforations remain a surgical challenge, prompting the development of new approaches and techniques to optimize closure rates. When symptomatic, perforations can cause nasal obstruction or recurrent epistaxis, requiring treatment. This study reports two clinical cases of symptomatic septal perforations. Objective: To describe the diagnosis, treatment, and surgical outcomes, accompanied by ...
Hearing loss in children with congenital cytomegalovirus infection
Caetano Oliveira, Gonçalo; Morgado, Filipa; Santos, Mariana; Mota, Clara; Matos, Ricardo; Robles, Raquel; Fonseca, RuiObjective: To study the prevalence of hearing loss in children with congenital Cytomegalovirus infection and the influence of the type of maternal infection, symptoms and neonatal treatment with valganciclovir. Study design: Retrospective cohort Material and Methods: Data was collected through computerized processes of children with congenital Citomegalovirus, followed in Hospital de Guimarães, between 2017 and...
Polycomb group (PcG) proteins prevent the assembly of abnormal synaptonemal com...
Feijão, Tália; Marques, Bruno; Silva, Rui D.; Carvalho, Célia; Sobral, Daniel; Matos, Ricardo; Tan, Tian; Pereira, António; Morais de Sá, EuricoThe synaptonemal complex (SC) is a proteinaceous scaffold that is assembled between paired homologous chromosomes during the onset of meiosis. Timely expression of SC coding genes is essential for SC assembly and successful meiosis. However, SC components have an intrinsic tendency to self-organize into abnormal repetitive structures, which are not assembled between the paired homologs and whose formation is po...
Influence of the nurse-patient ratio on physical restraint in psychiatry: syste...
Matos, Ricardo; Cruz, Ana; Ferreira, Bruna; Gonçalves, Carla; Correia, Diana; Almeida, EmanuelBackground: physical restraint in psychiatric services is a common practice, which can compromise a person’s freedom, self-determination, dignity and life. Associated with efforts to minimize the use of this measure, the nurse-patient ratio factor has been little studied. Objective: to analyze the influence of the nurse-patient ratio in psychiatric services on the use of physical restraint and isolation. Method...

Intestinal Duplication: A Rare Cause of Occlusion in Adults
Silva, Nádia Rodrigues; Gomes, Diogo Carrola; Matos, Ricardo; Paixão, IsabelDuplication of the digestive tract is a rare condition, usually diagnosed at a young age. Late diagnosis can be associated with complications such as bowel obstruction, hemorrhage, or perforation.We present the case of a 60-year-old patient admitted to the emergency department due to abdominal pain and constipation.In the computed tomography scan, she presented a large fecaloma of the sigmoid colon causing larg...
EmuCD: an emulator for content dissemination protocols in vehicular networks
Chaves, Ricardo; Senna, Carlos; Luís, Miguel; Sargento, Susana; Moreira, André; Recharte, Diogo; Matos, RicardoThe development of protocols for mobile networks, especially for vehicular ad-hoc networks (VANETs), presents great challenges in terms of testing in real conditions. Using a production network for testing communication protocols may not be feasible, and the use of small networks does not meet the requirements for mobility and scale found in real networks. The alternative is to use simulators and emulators, but...
NineTeen Complex-subunit Salsa is required for efficient splicing of a subset o...
Rathore, Om Singh; Silva, Rui D; Ascensão-Ferreira, Mariana; Matos, Ricardo; Carvalho, Célia; Marques, Bruno; Tiago, Margarida N.; Prudêncio, PedroThe NineTeen Complex (NTC), also known as pre-mRNA-processing factor 19 (Prp19) complex, regulates distinct spliceosome conformational changes necessary for splicing. During Drosophila midblastula transition, splicing is particularly sensitive to mutations in NTC-subunit Fandango, which suggests differential requirements of NTC during development. We show that NTC-subunit Salsa, the Drosophila ortholog of human...

Regulation of gene expression during Drosophila oocyte development
Matos, RicardoHuman oocytes can stay dormant for several decades in meiotic arrest, before reactivation and maturation. Similar, Drosophila oocyte is mostly transcriptionally quiescent during prophase I-arrest, transiently reactivating gene expression just before it progresses into metaphase I. Our aim is to better understand such reactivation and its role for oocyte maturation and female fertility. This work is divided in 3...
