Potential of portuguese viticulture by-products as natural resources of bioacti...

Vitis vinifera is the grape variety used in the production of wine and other products. In the wine production process, many of the vine’s by-products are wasted, namely seeds and stems. Given the proportion of wine production worldwide, the quantity of by-products is beginning to be an environmental problem, making it urgent to take measures for their use to obtain bioactive compounds with health benefits. The ...

Validity of central pain processing biomarkers for predicting the occurrence of...

Despite recent improvements in cancer detection and survival rates, managing cancer-related pain remains a significant challenge. Compared to neuropathic and inflammatory pain conditions, cancer pain mechanisms are poorly understood, despite pain being one of the most feared symptoms by cancer patients and significantly impairing their quality of life, daily activities, and social interactions. The objective of...

FAAH rs324420 polymorphism is associated with performance in elite rink-hockey ...

Genetic factors are among the major contributors to athletic performance. Although more than 150 genetic variants have been correlated with elite athlete status, genetic foundations of competition-facilitating behavior influencing elite performances are still scarce. This is the first study designed to examine the distribution of genetic determinants in the athletic performance of elite rink-hockey players. A t...

Cervical cancer outcome and tumor-associated macrophages: research evidence

Inflammation is a key factor in cancer promotion. Tumor-associated macrophages (TAMs), as part of the tumor microenvironment, are often associated with the progression of tumors and a worse prognosis in many cancers, namely on cervical cancer. This work exhaustively summarizes the conclusions of the different studies published concerning TAMs function in cervical cancer, from in vitro studies using cancer cell ...

Role of genetic polymorphisms on neuroplasticity pathways in a cohort of Portug...

Growing evidence suggests the implication of brain plasticity in antidepressant drug (AD) efficacy. Several authors have been pointing out the role of the BDNF-TrkB signaling pathway, including the downstream kinases Akt and ERK, and the mTOR pathway in neuroplasticity [1-3]. Furthermore, the prediction of AD response phenotypes of depressed patients treated with AD drugs remains a challenge for clinicians. Alt...

Effect of 1-carbaldehyde-3,4-dimethoxyxanthone on prostate and HPV-18 positive ...

Xanthone derivatives have shown promising antitumor properties, and 1-carbaldehyde-3,4- dimethoxyxanthone (1) has recently emerged as a potent tumor cell growth inhibitor. In this study, its effect was evaluated (MTT viability assay) against a new panel of cancer cells, namely cervical cancer (HeLa), androgen-sensitive (LNCaP) and androgen-independent (PC-3) prostate cancer, and nonsolid tumor derived cancer (J...

Mechanism of antifungal activity by 5-aminoimidazole-4-carbohydrazonamide deriv...

Systemic mycoses are one major cause of morbidity/mortality among immunocompromised/debilitated individuals. Studying the mechanism of action is a strategy to develop safer/potent antifungals, warning resistance emergence. The major goal of this study was to elucidate the mechanism of action of three (Z)-5-amino-N’-aryl-1-methyl-1H-imidazole-4-carbohydrazonamides (2h, 2k, 2l) that had previously demonstrated st...

Prevalence of Neisseria gonorrhoeae and Trichomonas vaginalis in portuguese wom...

Omega 3 and resveratrol loaded lipid nanosystems for potential use as topical f...

Resveratrol (RSV) and omega 3 (ω3), because of their biological favorable properties, have become subjects of interest for researchers in dermocosmetic and pharmaceutical industries; however, these bioactives present technological limitations that hinder their effective delivery to the target skin layer. To overcome the stability and skin permeation limitations of free bioactives, this work proposes a combined ...

1,2-dihydroxyxanthone: effect on A375-C5 melanoma cell growth associated with i...

Xanthones have been suggested as prospective candidates for cancer treatment. 1,2- dihydroxyxanthone (1,2-DHX) is known to interfere with the growth of several cancer cell lines. We investigated the effects of 1,2-DHX on the growth of the A375-C5 melanoma cell line and THP-1 human macrophage activity. 1,2-DHX showed a moderate growth inhibition of A375-C5 melanoma cells (concentration that causes a 50% inhibiti...
