Around two million tons of olive oil are produced in Europe annually, with Portugal being among the top five European oil-producing countries. Olive production results a substantial amount waste form leaves. These discarded leaves contain valuable phenolic compounds antioxidant, anti-inflammatory, hypoglycaemic, neuroprotective, and antiproliferative properties. Due to their richness polyphenols health-promoting properties, can be considered potential functional food ingredient. Thus,...

The analysis and interpretation of data retrieved from Oxygen Radical Absorbance Capacity (ORAC) assays represent a challenging task. ORAC indexes originate different mathematical approaches often lacking correct elucidation kinetic features concerning radical scavenging reactions by antioxidant compounds. In this work, the expression values as area under fluorescein (FL) decay curves (AUC) lag time are critically compared. This multi-parametric showed extension beyond period for caffeic...

Vascular calcification (VC) is a frequent condition in chronic kidney disease (CKD) and well-established risk factor for the development of cardiovascular (CVD). Gut dysbiosis may contribute to CVD inflammation CKD patients. Nonetheless, role gut blood microbiomes CKD-associated VC remains unknown. Therefore, this pilot study aimed explore link between patients on peritoneal dialysis (CKD-PD). Our results showed relative changes specific taxa CKD-PD with without VC, namely Coprobacter,...

Green and environmentally friendly approaches are increasingly necessary when developing new analytical methodologies. Electromembrane extraction (EME) has contributed to this by offering alternatives the traditional widely used plastic materials. Specially, those derived from biopolymers (such as agarose or chitosan) have recently gained a great importance in EME they biodegradable sustainable, which constitutes major advantage environmental impact of these processes. This review is...

Summary A bacterial mixed culture able to mineralize molinate was established, through enrichment, using mineral medium with as the only carbon, nitrogen and energy source. The combination of five cultivable isolates, purified from enrichment culture, permitted reconstitution a degrading consortium. Both defined cultures were without accumulation degradation products by end growth. Among isolates constituting an actinomycete, strain ON4, essential for biodegradation, being involved in...

Antiretroviral drug nanocarriers hold great promise for developing anti-human immunodeficiency virus (HIV) rectal microbicides. However, challenges remain, namely, concerning which properties are more suited enhancing colorectal distribution and retention of microbicide compounds. In this work, we developed assessed the in vitro vivo performance poly(lactic-co-glycolic acid) (PLGA)-based nanoparticles (NPs) as carriers model efavirenz (EFV). We particularly focused on effect noncovalent...
