Active Low-Density Polyethylene-Based Films by Incorporating α-Tocopherol in th...

In this work, alpha-tocopherol (α-TOC) was encapsulated in poly(lactic acid) nanoparticles (PLA NPs) and added to low-density polyethylene (LDPE) films with the aim of producing an active film for food packaging applications. PLA NPs loaded with α-TOC were produced through nanoprecipitation and dried using two methods (freeze-dryer and oven). LDPE-based films with final polymeric matrix concentrations of 10 and...

LDPE-Nanoclay films for food packaging with improved barrier properties

This study focuses on the development of low-density polyethylene matrix nanocomposite films for food packaging industry and aims at improving low-density polyethylene oxygen barrier properties while maintaining other relevant characteristics, such as processability, easy post-processing, optical and mechanical properties. low-density polyethylene nanocomposites, with 1 and 2.5 wt.% nanoclay (NC) and also compa...

Active Flexible Films for Food Packaging: A Review

Active food packaging is a dynamic area where the scientific community and industry have been trying to find new strategies to produce innovative packaging that is economically viable and compatible with conventional production processes. The materials used to develop active packaging can be organized into scavenging and emitting materials, and based on organic and inorganic materials. However, the incorporatio...

Selected Uterine Immune Events Associated With the Establishment of Pregnancy i...

In the dog, implantation takes place at approximately 17 days of embryonal life and, while exposed to relatively high circulating progesterone concentrations, embryos presence is required for the formation of decidua. Furthermore, a balance between pro- and anti-inflammatory responses in conceptus-maternal communication is crucial for the onset of pregnancy. Strikingly, the understanding of such immune mechanis...

Early embryo development, number, quality, and location and the relationship wi...

This research assessed the developmental stages and morphological quality of dog embryos collected during different stages of pregnancy as well as the relationship with serum progesterone recorded at insemination and embryo collection. Embryos were collected from 23 young mature bitches, that had been inseminated with fresh semen 3-6 days after the LH surge (day 0). Embryo flushing was performed on pregnancy da...

Temporal changes in Neutral Endopeptidase/CD10 immunoexpression in the cyclic a...

CD10 is a multifunctional transmembrane neutral endopeptidase (NEP), considered to be a reliable marker of ectopic human endometrial stroma. Available information in NEP/CD10 protein expression in animal endometria is scarce. This study focused on the immunolocalization of NEP/CD10 in the canine uterus and on its temporal changes during the oestrous cycle and early pregnancy (days 11 to 23 post-LH surge) in hea...

Relatório de Trabalho de Projeto: suscetibilidade e controle da infeção no doen...

O Doente Oncológico Neutropénico/Suscetível é uma realidade em muitos serviços, estado que associado a infeções oportunistas e a microrganismos multirresistentes consiste numa crescente preocupação nos dias de hoje. Uma eficaz prevenção e um eficiente controlo da infeção torna-se um desafio para todos os profissionais de saúde, principalmente quando o controle de custos e gastos deverá ser uma constante. Neste ...
