Paving the way for a non‐antibiotic and microbiota friendly therapy for Helicob...

Background: The World Health Organization has identified Helicobacter pylori, a Gram-negative bacterium responsible for several gastric disorders, as one of the pathogenic bacteria that requires newer non-antibiotic approaches for its management. We previously demonstrated that nanostructured lipid carriers (NLC) loaded with docosahexaenoic acid (DHA-NLC)have excellent in vitro performance against H. pylori. Ma...

Field and Molecular Epidemiology: How Viral Sequencing Changed Transmission Inf...

Field epidemiology and viral sequencing provide a comprehensive characterization of transmission chains and allow a better identification of superspreading events. However, very few examples have been presented to date during the COVID-19 pandemic. We studied the first COVID-19 cluster detected in Portugal (59 individuals involved amongst extended family and work environments), following the return of four rela...

Dynamics of a Dual SARS-CoV-2 Lineage Co-Infection on a Prolonged Viral Sheddin...

A few molecularly proven severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cases of symptomatic reinfection are currently known worldwide, with a resolved first infection followed by a second infection after a 48 to 142-day intervening period. We report a multiple-component study of a clinically severe and prolonged viral shedding coronavirus disease 2019 (COVID-19) case in a 17-year-old Portuguese f...

Shedding light on the african enigma: In vitro testing of homo sapiens-helicoba...

The continuous characterization of genome-wide diversity in population and case- cohort samples, allied to the development of new algorithms, are shedding light on host ancestry impact and selection events on various infectious diseases. Especially interesting are the longstanding associations between humans and certain bacteria, such as the case of Helicobacter pylori, which could have been strong drivers of a...

Genomic insights into the human susceptibility to SARS-CoV-2 infection

Hypoxia and macrophages act in concert towards a beneficial outcome in colon ca...

In colon cancer, the prognostic value of macrophages is controversial, and it is still unknown how hypoxia modulates macrophage–cancer cell crosstalk. To unravel this, co-cultures of human primary macrophages and colon cancer cells were performed at 20% and 1% O2, followed by characterization of both cellular components. Different colon cancer patient cohorts were analyzed for hypoxia and immune markers, and th...

Síndrome Cardio-Renal: os desafios no tratamento da insuficiência cardíaca

Heart failure is a chronic and progressive disease that is estimated to affect approximately 20 million people worldwide and is one of the major public health problems. Its prevalence is reaching epidemic levels with about 550,000 new cases diagnosed annually, partly due to increased life expectancy in developed countries. And as it is a systemic disease, it can cause dysfunction in various organs, but especial...

Doença celíaca: revisão de conceitos e novos desenvolvimentos
