Portuguese Validation of a Reduced Version of the IAT (Internet Addiction Test)...

Abstract: This study adapted and assessed a shortened version of the IAT (Internet Addiction Test) scale completed by young people aged 12 years and older regarding their online behaviors and risk of online addiction. The psychometric qualities of the reduced version (Screening IAT—youth) are presented in order to validate the use of this version in the early detection of online addiction. The total sample was ...

A One pathology multicentre Portuguese approach to thyroid tumours of dogs and ...

Thyroid tumours are the most common endocrine tumours of dogs and cats. Feline thyroid tumours are essentially functional adenomas curable with thyroidectomy, whereas most canine thyroid tumours are non-functional carcinomas either unresectable or recurrent within two years in up 50%. The oncobiology of these tumours remains unclear, but investigating this aspect could contribute to the development of targeted ...

Generation of an obese diabetic mouse model upon conditional Atrx disruption

ATRX mutations occur in up to 17% of human pancreatic neuroendocrine tumours (PanNETs), and recent evidence points towards its inability to drive PanNET formation in mouse pancreas while predisposing individuals to inflammageing. Aiming to explore the additional non-tumourigenic consequences of Atrx deletion, we characterised an aged series of Atrx conditional disruption in β cells using the Pdx1 promoter. Homo...

The osteogenic and mineralogenic potential of the microalgae Skeletonema costat...

Skeletal disorders are problematic aspects for the aquaculture industry as skeletal deformities, which affect most species of farmed fish, increase production costs and affect fish welfare. Following recent findings that show the presence of osteoactive compounds in marine organisms, we evaluated the osteogenic and mineralogenic potential of commercially available microalgae strains Skeletonema costatum and Tet...

Image philosophy for reading glitch art

This article investigates to what extent it is possible to establish an image philosophy to read digital images, in this specific case, applying the concepts in the areas of glitch art. For this, we sought, through a systematic literature review, general definitions about the terms of the image and developed a possible approach for reading digital images that have intrusive aesthetic data from the operation of ...

Correlates of online dependence during the covid-19 pandemic

Several variables were associated with online dependence, but it is unclear to what extent they are independently associated. We examined the following statistical predictors of online dependence: food addiction, poor sleep quality, absence of physical activity, negative family interactions, positive family interactions, and age, in a sample of Portuguese adolescents and young adults during the COVID-19 pandemi...

Toxicological and anti-tumor effects of a linden extract (Tilia platyphyllos Sc...

Tilia platyphyllos Scop. is a popular broad-leaved tree, native to Central and Southern Europe. Hydroethanolic extracts rich in phenolic compounds obtained from T. platyphyllos Scop. have shown in vitro antioxidant, anti-inflammatory and antitumor properties. The aim of this work was to evaluate the therapeutic properties of a hydroethanolic extract obtained from T. platyphyllos in HPV16-transgenic mice. The an...

Avaliação in vivo dos efeitos fisiológicos resultantes da exposição à tília

O Papiloma Vírus Humano (HPV) é responsável pelo desenvolvimento do carcinoma do colo do útero, estando ainda associado a outros carcinomas. Para compreender melhor os mecanismos associados às infeções causadas por este vírus e estudar novas terapias foi desenvolvido um modelo transgénico de murganho: K14HPV16. Assim, o objetivo deste trabalho foi avaliar o efeito da administração oral do extrato hidroetanólico...
