Clinical Outcomes of Thoracic Cancer Patients Requiring ICU Admission: A 10-Yea...

IntroductionLung cancer is the most common solid malignancy requiring intensive care unit (ICU) admission, but ICU admission for cancer patients is often denied, being the second most common reason for refusal. This study aimed to evaluate the outcomes of thoracic cancer patients admitted to the ICU and understand the characteristics that may affect these outcomes. MethodsThis retrospective cohort study analyze...

Assessment of the Antimicrobial Activity of L. and (L.) DC Extracts and Their S...

This study aimed to evaluate the antibacterial activity of L. and (L.) DC extracts against , including methicillin-resistant (MRSA) strains. To this end, assays were conducted to assess killing kinetics, antibiotic combination effects, modulatory effects on ethidium bromide, inhibition of quorum sensing, and biofilm formation. extract demonstrated the strongest activity, with MIC values ranging from 7.8 to 62.5...

Bioactive Potential of Wild Plants from Gardunha Mountain: Phytochemical Charac...

The plants used in folk medicine have been increasingly studied to identify their bioactive properties. Therefore, this study aimed to assess the bioactivity of the hydroethanolic extracts of plants collected in Gardunha Mountain, Portugal. Seven abundant and representative wild plants were studied: , , , , , , and . The phytochemical composition of the extracts was determined by UHPLC-timsTOF-MS and by spectro...

The dual action of probiotic lactobacilli in suppressing virulence and survival...

Arcobacter butzleri is a widely distributed foodborne and waterborne pathogen, increasingly recognized as an emerging enteropathogen. Understanding its survival mechanisms and interactions with probiotics is crucial for developing targeted intervention strategies. A. butzleri must withstand various hostile conditions to successfully colonize the gastrointestinal tract, including inhibition by probiotics, such a...

The influence of short-chain fatty acids on the survival and virulence of Arcob...

Aims: Arcobacter butzleri, a widespread bacterium linked to gastrointestinal disease, can bypass host colonization resistance mechanisms; however, its response to short-chain fatty acids (SCFAs) remains poorly understood. This study investigated the impact of SCFAs on A. butzleri ’s survival and virulence. Methods and results: Eight A. butzleri isolates were assessed under varying concentrations of individual S...

Production and Characterization of a Pullulan-Based Facial Mask Incorporating G...

This study aimed to develop and characterize an eco-friendly facial mask based on the pullulan biopolymer incorporating grape seed flour extract, a sustainable source of polyphenols. The extract was characterized by its phenolic content, antioxidant capacity, enzyme inhibition and antimicrobial activity. High total phenolic and flavonoid contents, along with the presence of -resveratrol, conferred strong antiox...

Evaluation of Bile Salts on the Survival and Modulation of Virulence of Aliarco...

Aliarcobacter butzleri is a Gram-negative bacterium associated with infections of the gastrointestinal tract and widely distributed in various environments. For successful infection, A. butzleri should be able to tolerate various stresses during gastrointestinal passage, such as bile. Bile represents an antimicrobial host barrier that acts against external noxious agents and consists of a variety of bile salts....

Migrações na Fronteira Sul da União Europeia: o Dever de Assistência dos Estado...

O Mediterrâneo converteu-se neste século XXI num espaço de exceção através da implementação de medidas dissuasórias às migrações irregulares, dentro do quadro normativo da União Europeia (UE). A gestão das migrações nesta fronteira meridional da Europa é um dos desafios mais significativos que a UE e os seus Estados-membros enfrentam na atualidade, onde a procura de um equilíbrio entre a garantia dos direitos h...
