Ecotoxicity of the non-dioxin-like PCB-153 in the model marine diatom Phaeodact...

Despite the ban on polychlorinated biphenyls (PCBs) in developed countries since the 1930s, their persistence and use endured in developing countries, with reported toxic effects on various organisms. PCB congener 153 (PCB-153, 2, 2′, 4, 4′, 5, 5′–hexachlorobiphenyl) is notably prevalent in marine biota. However, its mode of action and impact on primary marine diatoms are not well documented. Phaeodactylum tric...

Influence of orchards fertilization management and post-harvest storage time on...

“Maçã de Alcobaça” is a type of apple from the West coast of Portugal with Protected Geographical Indication (PGI). This study evaluated the influence of the orchard’s fertilization and post-harvest storage time on the quality of “Maçã de Alcobaça”, ‘Gala’ cultivar. Five orchards were studied for four years, using three fertilization treatments [Standard, twice Standard (2xStandard) and twice Standard including...

Land use change effects on soil physical-chemical parameters and microbial comm...

Current studies show a decline in soil biodiversity, which puts at risk future food production since soil organisms play a key role in essential ecosystem functions such as, nutrient cycling and soil fertility, soil carbon sequestration, climate regulation, litter decomposition, erosion, water retention, interaction with plants, among others. This study aims to evaluate how the conversion of a tropical native f...

Marine microbial community taxonomic and functional indicators to volcanic and ...

In recent years, the growth in Antarctic tourism has stimulated research on the anthropogenic impacts on the region, boosted by advances in OMIC technologies applied to polar microbial communities. This study aimed to assess the human impacts on marine prokaryotic and viral communities of Deception Island by identifying potential taxonomic, functional, and resistome indicators of both anthropogenic and natural/...

Hemolytic Uremic Syndrome and SARS-CoV-2 Infection: A Rare Association

Thrombotic microangiopathies (TMA) are rare diseases,with high morbimortality. Among them, atypical hemolytic uremic syndrome (HUS), associated with deregulation of alternative complement pathway (genetic/acquired), represents a diagnostic challenge. Characterized by thrombotic microangiopathy, acute renal failure is one of its main features. Etiological/ precipitant detection (TMA triggers) is essential, even ...

Redesign of the internal logistics system of a textile supplier for the automot...

The aim of this work is the design, implementation and evaluation of an internal logistic system based on a combination of Mizusumashi and e-Kanban, within a company of textile reinforcements production for the automotive industry. A critical review of literature allowed the selection of a set of steps for designing the Mizusumashi and e-Kanban systems, namely: specification of the quantity of material to be ha...

The use of chitosan oligosaccharide to improve artemisinin yield in well-watere...

Introduction: Artemisinin is a secondary metabolite well-known for its use in the treatment of malaria. It also displays other antimicrobial activities which further increase its interest. At present, Artemisia annua is the sole commercial source of the substance, and its production is limited, leading to a global deficit in supply. Furthermore, the cultivation of A. annua is being threatened by climate change....
