Relatório científico da Expedição Oceano Azul - Cascais | Mafra | Sintra

A zona marítima dos concelhos de Cascais, Mafra e Sintra tem sido pouco estudada, não obstante situar-se frente a grandes centros urbanos e ser alvo de diversos usos e atividades humanas. Algumas das suas características geográficas e dos seus elementos notáveis ao nível dos fundos marinhos acrescem o seu interesse científico e patrimonial. Com o objectivo de ampliar o conhecimento científico sobre a biodiversi...

A review of synthetic-aperture radar image formation algorithms and implementat...

Designing synthetic-aperture radar image formation systems can be challenging due to the numerous options of algorithms and devices that can be used. There are many SAR image formation algorithms, such as backprojection, matched-filter, polar format, Range–Doppler and chirp scaling algorithms. Each algorithm presents its own advantages and disadvantages considering efficiency and image quality; thus, we aim to ...

How Relevant is the Systemic Oxytocin Concentration for Human Sexual Behavior? ...

Introduction: Despite its role in social cognition and affiliative behavior, less is known about the role played by oxytocin in human sexual behavior. Aim: In the present systematic review, we aimed to find the levels of oxytocin related to human sexual arousal and orgasm. Methods: We conducted the study according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We ...

Resposta à Covid-19: o que foi feito e o que há para fazer

Progression of rabbit haemorrhagic disease virus 2 upon vaccination in an indus...

Rabbit haemorrhagic disease virus 2 (RHDV2) emerged recently in several European countries, leading to extensive economic losses in the industry. In response to this new infection, specific inactivated vaccines were developed in Europe and full and rapid setup of protective immunity induced by vaccination was reported. However, data on the efficacy of these vaccines in an ongoing-infection scenario is unavailab...

Investigating the existence of social networks in cheating behaviors in medical...

Background: Most studies on academic cheating rely on self-reported questionnaires and focus on the individual, overlooking cheating as a group activity. The aim of this study is to estimate the true prevalence of cheating/anomalies among medical students using a statistical index developed for this purpose, and to explore the existence of social networks between anomalies in students' results. Methods: Angoff'...

Vancomycin therapeutic drug monitoring and population pharmacokinetic models in...

Vancomycin is a fundamental antibiotic in the management of severe Gram-positive infections. Inappropriate vancomycin dosing is associated with therapeutic failure, bacterial resistance and toxicity. Therapeutic drug monitoring (TDM) is acknowledged as an important part of the vancomycin therapy management, at least in specific patient subpopulations, but implementation in clinical practice has been difficult b...

SRC inhibition prevents P-cadherin mediated signaling and function in basal-lik...

BACKGROUND: Basal-like breast cancer (BLBC) is a poor prognosis subgroup of triple-negative carcinomas that still lack specific target therapies and accurate biomarkers for treatment selection. P-cadherin is frequently overexpressed in these tumors, promoting cell invasion, stem cell activity and tumorigenesis by the activation of Src-Family kinase (SRC) signaling. Therefore, our aim was to evaluate if the trea...

Acute Confusional State after Inhaled Corticotherapy

Background: The connection between corticotherapy and neuropsychiatric symptoms is widely known, being one of the first questions we need to assess when presenting with first episode psychiatric symptoms or confusional state. Aims: To date, data on cases related to inhaled corticotherapy and neuropsychiatric effects is scarce. In this paper we describe a rare case in a young woman. Methods: The clinical case pr...
