Biosynthesis of Silver-Based Nanoparticles Using Supernatants of Microbial Cult...

Microbial contamination of Cultural Heritage (CH) materials is one of its most prevalent and impacting preservation issues that can lead to visual, structural, and chemical changes1. Currently, different approaches try to address this issue by employing products and techniques that can lead to structural or chemical alteration of materials2 and pose several environmental risks3. For these reasons, nanotechnolog...

Biosynthesis of silver-based nanoparticles: Critical assessment of antimicrobia...

Synthesis and application of nanoparticles (NPs) have shown promising results in various scientific fields due to their differentiating properties. However, current nanoparticle synthesis methods present environmental challenges. In this study biosynthesized silver nanoparticles (AgNPs) were produced from microbial culture supernatants as an alternative to traditional routes for controlling biodeteriogenic micr...

Climate Effect on Morphological Traits and Polyphenolic Composition of Red Wine...

Wine quality is determined by the development of grape maturation, which is highly dependent on climate variations. Extreme weather events are becoming more common, which will affect the productivity and quality of grapes and wine. Grape development depends on many factors, including weather, and extreme events will influence berry size, skin thickness and the development of some key compounds, such as phenolic...

Biosynthesis of Metal and Metal Oxide Nanoparticles Using Microbial Cultures: M...

Nanoparticles (1 to 100 nm) have unique physical and chemical properties, which makes them suitable for application in a vast range of scientific and technological fields. In particular, metal nanoparticle (MNPs) research has been showing promising antimicrobial activities, paving the way for new applications. However, despite some research into their antimicrobial potential, the antimicrobial mechanisms are st...

Quality Assessment of Red Wine Grapes through NIR Spectroscopy

Red wine grapes require a constant follow-up through analytical chemistry to assure the greatest wine quality. Wet chemical procedures are time-consuming and produce residues that are hard to eliminate. NIR (near infrared radiation) spectroscopy has been referred as an accurate, rapid, and cost-efficient technique to evaluate quality in many fruit species, both in field and in industry. The main objective of th...

Trabalho Livre nº 20 - Registos de Enfermagem no Tratamento de Feridas Complexas

Os registos de enfermagem devem seguir normas e critérios objectivos de modo a permitir a continuidade da prestação de cuidados de qualidade ao utente de forma individualizada. Inclusivamente, na perspectiva de Silvestre (2012), os registos de enfermagem assumem um importante papel na avaliação e monitorização da ferida, no qual incluem o diagnóstico inicial da ferida, a sua evolução em resposta às intervenções...

Trabalho Livre nº 09 - Feridas Complexas: estudos de caso no tratamento de lesã...

As lesões por pressão são danos localizados na pele e/ou tecidos subjacentes, resultantes de pressão isolada ou combinada com forças de cisalhamento e/ ou fricção, normalmente sobre uma proeminência óssea (National Pressure Ulcer Advisory Panel, 2016). Com a pressão ocorre a diminuição do fluxo sanguíneo ao local pressionado e a falta de oxigenação; o que pode levar à Lesão.

Gongronella eborensis sp. nov., from vineyard soil of Alentejo (Portugal)

This study describes a novel fungal species belonging to the genus Gongronella. During a previous work focusing on metalaxyl degradation by Mucorales strains, two isolates from vineyard soil samples collected in the Alentejo region, south Portugal, were identified as a putative novel species based on combined molecular and MALDI-TOF MS data. This new species is described here using a polyphasic approach that co...
