Listeria monocytogenes gut interactions and listeriosis: gut modulation and pat...

Following ingestion via contaminated food, Listeria monocytogenes faces multiple hurdles through the human digestive system, thereby influencing its capacity to cause infection. This review provides a comprehensive overview of the multifaceted mechanisms employed by L. monocytogenes to overcome gastrointestinal hurdles and interact with the host's microbiota, facing chemical and physical barriers such as saliva...

The Prevalence of Aberrant Nasal Turbinates and Nasal Septum Deviation in a Fre...

The presence of nasal septum deviation and aberrant turbinates alters the normal nasal airflow. The relevance of nasal septum deviation in the brachycephalic obstructive airway syndrome (BOAS) is still unclear but, together with other anatomical alterations such as aberrant turbinates, may alter the normal nasal airflow, increasing upper airway resistance. The present retrospective study reports the prevalence ...

The impact of gamification on consumer engagement with brands: Empirical evidence

This study investigates the impact of gamification on consumer brand engagement among Portuguese gamers, addressing a significant gap in empirical research within this demographic. While gamification is known for enhancing brand engagement and loyalty, limited evidence exists in the Portuguese market. Using a quantitative approach, data were collected from 485 Portuguese gamers and analyzed through covariance-b...

Estudo com psicólogos brasileiros sobre o uso da prática da Psicologia baseada ...

A psicologia enquanto ciência, além de profissão, vem se consolidando nos últimos anos e o que caracteriza o conhecimento científico como diferente do conhecimento advindo do senso comum é o método. Enquanto o senso comum tem um caráter subjetivo, intuitivo e assistemático, o conhecimento científico tem um rigor metodológico, se baseia em fatos, é sistemático e passível de verificação (Araújo, 2006; Marconi, & ...

In vitro toxicity assessment of firefighters’ breathable air collected on polyu...

Background: Occupational exposure as a firefighter has been recently classified as carcinogenic to humans (Group 1) by the International Agency for Research on Cancer (IARC) [1]. Polycyclic aromatic hydrocarbons (PAH) are one of the main fire-related pollutants [3], and their presence in the breathable air of firefighters was already demonstrated [4]. However, the toxicity mechanisms involved in such exposures ...

Psychological empowerment for the future of work: Evidence from Portugal

In the competitive global marketplace, it is becoming important for organizations to empower employees for productivity reasons. One of the organizational empowerment models with greater support and consistency in the various studies in which it has been used is Spreitzer's Model of Psychological Empowerment in the Workplace, published in 1995. The model is composed of four dimensions that allow the measurement...

Strategic perspective of error management the role of leadership and an error m...

Purpose – Errors are inevitable, resulting from the human condition itself, system failures and the interaction of both. It is essential to know how to deal with their occurrence, managing them. However, the negative tone associated with them makes it difficult for most organizations to talk about mistakes clearly and transparently, for fear of being harmed, preventing their detection, treatment and recovery. C...

Urinary biomonitoring in firefighters: baseline data of polycyclic aromatic hyd...

Polycyclic aromatic hydrocarbons (PAHs) are among the most relevant pollutants in the firefighting context and urine the most straightforward and interesting matrix for biomonitoring. Recent studies have found elevated levels of PAH metabolites in firefighters in comparison to the general population. Since Portuguese firefighters are poorly characterized, the aim of this study was to determine the baseline data...

Controlling properties of ceramic formulations for porcelain robocasting

Porcelain pastes (PlotPastes) were formulated to be used on an additive manufacturing (AM) process (material extrusion) process, primarily robocasting (R3D) technique. The material morphological and thermal characteristics were evaluated by scanning electron microscopy (SEM), differential thermal analysis (DTA) and thermogravimetric analysis (TGA). The rheology and the electrical potential of the ceramic partic...
