Clinical impact of HFE Mutations in portuguese patients with Chronic Hepatitis C
Ferreira, Joana; Baldaia, Cilénia; Inácio, Ângela; Bicho, Manuel; Velosa, José; Faustino, Paula; Serejo, FátimaINTRODUCTION: Chronic hepatitis C (CHC) is often associated with alterations in iron and lipid metabolisms, which may affect the long-term prognosis and the response to antiviral treatment. Some studies suggested that the occurrence of HFE mutations may contribute to modulate these metabolisms in CHC. Here, the prevalence of two HFE mutations (C282Y and H63D) was determined in a group of Portuguese CHC patients...
In Vitro Surfactant Structure-Toxicity Relationships: Implications for Surfacta...
Inácio, Ângela S.; Mesquita, Katia A.; Baptista, Marta; Ramalho-Santos, João; Vaz, Winchil L. C.; Vieira, Otília V.Background The need for woman-controlled, cheap, safe, effective, easy-to-use and easy-to-store topical applications for prophylaxis against sexually transmitted infections (STIs) makes surfactant-containing formulations an interesting option that requires a more fundamental knowledge concerning surfactant toxicology and structure-activity relationships. Methodology/Principal Findings We report in vitro effect...
Interaction of PABPC1 with the translation initiation complex is critical to th...
Peixeiro, Isabel; Inácio, Ângela; Barbosa, Cristina; Silva, Ana Luísa; Liebhaber, Stephen; Romão, LuísaNonsense-mediated mRNA decay (NMD) is a surveillance pathway that recognizes and rapidly degrades mRNAs containing premature termination codons (PTC). The strength of the NMD response appears to reflect multiple determinants on a target mRNA. We have previously reported that mRNAs containing PTCs in close proximity to the translation initiation codon (AUG-proximal PTCs) can substantially evade NMD. Here, we exp...

Inácio, Ângela S; Mesquita, Katia A; Jordão, Luísa; Santos, Maria S; Moreno, António J M; Vaz, Winchil L C; Vieira, Otília VSexually transmitted infections (STIs) are a major public-health problem worldwide. According to the World Health Organization there are 340 million new cases of bacterial and protozoal STIs (Gonorrhea, Syphilis, Chlamydia and Trichomoniasis) per year. The direct treatment costs and serious perinatal collateral damage caused by STIs represent hefty financial and social burdens, particularly in developing countr...
