Microbial inoculants alleviate the adverse effects of Cu-contaminated soils ame...

Godinho, Mariana; Moreira, Helena; Castro, Paula Maria Lima; Pereira, Sofia Isabel Almeida

Soil contamination is a pressing global issue driven by various anthropogenic activities, such as mining. This study evaluated the use of biochar and microbial inoculants as phytoremediation allies in promoting sunflower growth in a Cu-contaminated mining soil. Sunflower seedlings were planted in a Cu-contaminated mining soil amended with increasing doses of biochar (0 %, 2.5 %, and 5 % w/w) under greenhouse co...

Glucans, structural polysaccharides in the yeast cell wall, are known for their biological and immunomodulatory capacities, helping in prevention and management of infections. Herpes simplex virus type 1 (HSVI) is a prevalent infection that causes great comorbidity and is challenging to treat due to the adverse effects of standard antiviral drugs like acyclovir. This study assessed the potential of yeast glucan...

Soil amendments and microbial inoculants can affect plant growth, water retention, and crop resilience. This study investigated the effects of two amendments, extracellular polymeric substances (EPS) and biochar, with and without bacterial inoculation, on maize (Zea mays) growth, irrigation needs, and physiological responses. Maize was cultivated in soil with 2.5 % and 5 % (w/w) of wet EPS (Kaumera®) or biochar...

Moreira, Helena; Moreira, Fernando; Jesus, Ângelo; Soares, M. Monteiro; Santos, P.; Moreira, Fernando; Jesus, Ângelo

Compreender os fatores que influenciam os profissionais de saúde nas suas preferências de prescrição na diabetes tipo 2, uma condição heterogénea e complexa, é fundamental para aprimorar a prática clínica. Este conhecimento também contribui para a personalização dos tratamentos de primeira linha, ajustando-os às características individuais ou a subgrupos específicos, com o objetivo de melhorar os resultados em ...


Impact of fertilization with cattle slurry in a poplar short rotation coppice o...

Rodrigues, Abel; Pereira, Sofia; Gomes, Alberto Azevedo; Louzada, José; Goncalves, Alexandre B.; Fonseca, Teresa; Castelo-Branco, Amélia; Castro, Paula

The incorporation of cattle slurry in soil in short-rotation-cycle poplar cultivations can be a win–win strategy, insofar as a main feedstock derived from local intensive dairy cattle breeding can be used as a natural fertilizer and in bioenergy produced in the same region. The circularity of this process can contribute to boosting local socio-economic value. In this context, this work involved the installation...

Pereira, Risla Elisabete; Antunes , Cristina; Alves, Emília; Teixeira, Andreia; Moreira, Carlos; Moreira, Helena

Women are more likely to experience depressive symptoms and poor quality of life during postmenopause. Physical activity is an effective strategy to improve the mental health of women in this climacteric phase. This study aimed to investigate the variation of depressive symptomatology and mood states in postmenopausal women as a function of moderate-vigorous physical activity (MVPA) levels. The search was condu...

Sleep parameters in postmenopausal women and their relationship with moderate-v...

Pereira, Risla Elisabete; Antunes, Cristina; Alves, Emília; Gabriel, Ronaldo; Moreira, Carlos; Moreira, Helena

Menopause is associated with decreased physical activity and sleep disturbances. Short sleep duration and poor sleep quality have been associated with an increased risk of falls, obesity, and type 2 diabetes. It´s important to understand how physical activity influences sleep health in postmenopausal women. The purpose of this study was to analyse the variation of sleep duration and quality as a function of mod...

Ferreira, João; Alves, Emília; Abrantes, Catarina; Gabriel, Ronaldo; Silva, Paulo; Moreira, Helena

Women in menopause have more mood swings than before menopause. Several studies attempt to clarify the role of menopause in the development of depression, anxiety, and stress in midlife. However, there is controversy about the relationship of body composition with psychological distress in postmenopausal women. This study investigated the relationship between fat mass (FM) and visceral fat level (FVL) with anxi...
