Functional properties and safety considerations of zinc oxide nanoparticles und...

Zinc oxide nanoparticles (ZnO NPs) exhibit diverse morphologies and sizes, influencing their functional properties. However, the relationship between their morphology and behavior under varying conditions remains poorly understood. This study provides novel insights by linking ZnO NPs shape to generation of reactive oxygen species (ROS), and to antimicrobial efficacy under varying temperatures. ROS generation w...

Spinal control of sexual excitation and copulatory behaviour

"This monograph is composed of five Chapters. Chapter 1 consists of a general introduction, where the relevant literature for this project is discussed. We start by generally describing sexual behaviour importance in several areas and then evolve to describing copulation in mammals and rodents. We highlight the differences in the copulatory sequence between rats and mice and why these differences may readout in...

Optimizing antimicrobial efficacy: investigating the impact of zinc oxide nanop...

Zinc oxide nanoparticles (ZnO NPs) have been investigated due to their distinct properties, variety of structures and sizes, and mainly for their antimicrobial activity. They have received a positive safety evaluation from the European Food Safety Authority (EFSA) for packaging applications as transparent ultraviolet (UV) light absorbers based on the absence of significant migration of zinc oxide in particulate...

Adapted chester step test can have maximal response characteristics for the ass...

Chester step test (CST) estimates the exercise capacity through a submaximal response, which can limit its application in the prescription of exercise. This study aimed to assess whether an adaptation of the CST (with a progressive profile) can have maximal response characteristics in young women and compare it to the incremental shuttle walk test (ISWT). Another aim was to determine its within-day test–retest ...

Influence of calcium acetate concentration in electrolyte on tribocorrosion beh...

Ti-based materials are widely used for dental and orthopaedic implant applications due to their adequate mechanical properties, corrosion behaviour and biocompatibility. However, these materials are biologically inert and display poor wear resistance. In one of the most studied processes that aims to overcome these drawbacks, Ti surfaces are often covered by anodic oxide films with the incorporation of bioactiv...

Preparation and characterization of bioactive chitosan-based films incorporated...

Chitosan films with olive leaf extract (OLE) incorporated at different concentrations were characterized regarding their antimicrobial, antioxidant and some relevant physical properties (i.e., solubility, water vapor permeability, and tensile properties). Results indicate that the active films have substantial antimicrobial activity against Listeria monocytogenes and Campylobacter jejuni mostly extending the mi...

O pai foi diagnostic...

Evaluation of the antiviral activity of an aqueous extract from Solidago virgau...

Herpes simplex virus type 2 (HSV-2) is widely distributed through the human population, infecting more than 500 million people globally [1]. Although typically causing mild diseases this virus may be responsible for severe infections, mainly in immunocompromised patients. Currently, there is a number of systemic antiviral agents against herpesvirus, the most commonly used being acyclovir and related drugs. Howe...
