Artificial Organs > 47 > 9 > 1490 - 1502

Background Veno‐venous extracorporeal membrane oxygenation (V‐V ECMO) is a lifesaving support modality for severe respiratory failure, but its resource‐intensive nature led to significant controversy surrounding its use during the COVID‐19 pandemic. We report the performance of several ECMO mortality prediction and severity of illness scores at discriminating survival in a large COVID‐19 V‐V ECMO...

Metabolic engineering strategies for butanol production in Escherichia coli

Sofia Ferreira, Rui Pereira, S. A. Wahl, Isabel Rocha

Biotechnology and Bioengineering > 117 > 8 > 2571 - 2587

The global market of butanol is increasing due to its growing applications as solvent, flavoring agent, and chemical precursor of several other compounds. Recently, the superior properties of n‐butanol as a biofuel over ethanol have stimulated even more interest. (Bio)butanol is natively produced together with ethanol and acetone by Clostridium species through acetone‐butanol‐ethanol fermentation,...

Chronic hepatitis C treatment in HIV co‐infection in Portugal: Results from a cohort OF 2133 patients presented by GEPCOI (Portuguese Coinfection Study Group)

Ana Cláudia Miranda, Josefina Mendez, Rosário Serrão, Francisco Vale, more

Journal of Viral Hepatitis > 27 > 7 > 715 - 720

Direct‐acting antiviral drugs (DAAs) have recently changed the paradigm of hepatitis C therapy, significantly improving treatment response rates, patient life expectancy and quality of life. In Portugal, sofosbuvir (SOF) and SOF/ledipasvir (SOF/LDV) were fully reimbursed by the National Health System since early 2015 and generalized use of interferon‐free DAA based regimens became current practice...

Discovery and implementation of a novel pathway for n-butanol production via 2-oxoglutarate

Sofia Ferreira, Rui Pereira, Filipe Liu, Paulo Vilaça, more

Biotechnology for Biofuels > 2019 > 12 > 1 > 1-14

Background One of the European Union directives indicates that 10% of all fuels must be bio-synthesized by 2020. In this regard, biobutanol—natively produced by clostridial strains—poses as a promising alternative biofuel. One possible approach to overcome the difficulties of the industrial exploration of the native producers is the expression of more suitable pathways in robust microorganisms such...

Maria J. Peixoto, Leonardo Magnoni, José F. M. Gonçalves, Robert H. Twijnstra, more

Journal of Applied Phycology > 2019 > 31 > 1 > 761-770

The current study evaluated the effects of two different fractions derived from the methanolic extraction of the red seaweed Gracilaria sp. supplemented in European seabass (Dicentrarchus labrax) diets. With that purpose, three experimental diets were prepared: a basal diet (control), a control supplemented with the methanolic extract (GE, 0.5% diet) and a control supplemented with the insoluble residue...

Enhanced resistance to citrus canker in transgenic sweet orange expressing the sarcotoxin IA gene

Adilson K. Kobayashi, Luiz Gonzaga E. Vieira, João Carlos Bespalhok Filho, Rui Pereira Leite, more

European Journal of Plant Pathology > 2017 > 149 > 4 > 865-873

Citrus canker, caused by the bacterial pathogen Xanthomonas citri subp. Citri (Xcc), is a serious disease reported in most citrus-producing areas around the world. Although different levels of field resistance to citrus canker have been reported in sweet oranges, they are usually not sufficient to provide adequate control of the disease. Ectopic over-expression of antibacterial genes is one of the...

2017 IEEE/ACM 39th International Conference on Software Engineering Companion (ICSE-C)

This paper briefly proposes a technique to detect energy inefficient fragments in the source code of a software system. Test cases are executed to obtain energy consumption measurements, and a statistical method, based on spectrum-basedfault localization, is introduced to relate energy consumption to the system's source code. The result of our technique is an energy ranking of source code fragments...

2017 IEEE/ACM 39th International Conference on Software Engineering Companion (ICSE-C) > 88 - 90

2017 IEEE/ACM 39th International Conference on Software Engineering Companion (ICSE-C)

This paper briefly presents a new approach for helping developers identify energy hot spots in their applications. Using tests cases, and statistical methods based on Spectrum-based Fault Localization, high energy consumption is related to the system's source code and a ranking of possible energy leaks are pointed. This technique is both language independent, and context level independent. Initial...

Cíntia Alves, Rui Pereira, Lourdes Prieto, Mercedes Aler, more

Forensic Science International: Genetics > 2017 > 28 > C > 219-224

DNA is a powerful tool available for forensic investigations requiring identification of species. However, it is necessary to develop and validate methods able to produce results in degraded and or low quality DNA samples with the high standards obligatory in forensic research. Here, we describe a voluntary collaborative exercise to test the recently developed Species Identification by Insertions/Deletions...

Improving the flux distributions simulated with genome-scale metabolic models of Saccharomyces cerevisiae

Rui Pereira, Jens Nielsen, Isabel Rocha

Metabolic Engineering Communications > 2016 > 3 > Complete > 153-163

Genome-scale metabolic models (GEMs) can be used to evaluate genotype-phenotype relationships and their application to microbial strain engineering is increasing in popularity. Some of the algorithms used to simulate the phenotypes of mutant strains require the determination of a wild-type flux distribution. However, the accuracy of this reference, when calculated with flux balance analysis, has not...

DNA damage in oral epithelial cells of individuals chronically exposed to indoor radon (²²²Rn) in a hydrothermal area

Diana Paula Silva Linhares, Patrícia Ventura Garcia, Catarina Silva, Joana Barroso, more

Environmental Geochemistry and Health > 2018 > 40 > 5 > 1713-1724

Hydrothermal areas are potentially hazardous to humans as volcanic gases such as radon (²²²Rn) are continuously released from soil diffuse degassing. Exposure to radon is estimated to be the second leading cause of lung cancer, but little is known about radon health-associated risks in hydrothermal regions. This cross-sectional study was designed to evaluate the DNA damage in the buccal epithelial...
