Alginate-nanohydroxyapatite hydrogel system: Optimizing the formulation for enh...

Ceramic/polymer-based biocomposites have emerged as potential biomaterials tofill, replace, repair or re-generate injured or diseased bone, due to their outstanding features in terms of biocompatibility, bioactivity,injectability, and biodegradability. However, these properties can be dependent on the amount of ceramiccomponent present in the polymer-based composite. Therefore, in the present study, the influen...

What is the main processing factor influencing Staphylococcus species diversity...

The microbiota of traditional dry-cured sausages and industrial environment was assessed to characterize the diversity of coagulase-negative staphylococci (CNS), and establish potential relationships with hygiene level or technological characteristics. Eight processing units from South Portugal were audited according to a checklist of requirements. Environmental and products’ samples at different production sta...

Microanalysis of Bioactive Samarium Doped Glass-Reinforced Hydroxyapatite

Anti-sessile bacterial and cytocompatibility properties of CHX-loaded nanohydro...

Nanohydroxyapatite possesses exceptional biocompatibility and bioactivity regarding bone cells and tissues, justifying its use as a coating material or as a bone substitute. Unfortunately, this feature may also encourage bacterial adhesion and biofilm formation. Surface functionalization with antimicrobials is a promising strategy to reduce the likelihood of bacterial infestation and colonization on medical dev...

Sarcosine oxidase composite screen-printed electrode for sarcosine determinatio...

As the prostate cancer (PCa) progresses, sarcosine levels increase both in tumor cells and urine samples, suggesting that this metabolite measurements can help in the creation of non-invasive diagnostic methods for this disease. In this work, a biosensor device was developed for the quantification of sarcosine via electrochemical detection of H2O2 (at 0.6 V) generated from the catalyzed oxidation of sarcosine. ...

Novel Prostate Specific Antigen plastic antibody designed withcharged binding s...

This work shows that the synthesis of protein plastic antibodies tailored with selected charged monomersaround the binding site enhances protein binding. These charged receptor sites are placed over a neutralpolymeric matrix, thus inducing a suitable orientation the protein reception to its site. This is confirmed bypreparing control materials with neutral monomers and also with non-imprinted template. This con...

Evaluation of antibiotic susceptibility of Lactobacillus plantarum isolated fro...

Nowadays the use of fermentative microbiota in food products is researched in order to confer protection to the products and furnish health benefits to consumers The aim of this work was to evaluate antibiotics susceptibility of Lactobacillus plantarum isolated from fermented traditional meat products in order to select them to be used as starters or protective bacteria on fermented meat products. The susceptib...

Antimicrobial susceptibility assessment of Campylobacter on outdoor iberian pig...

Both Campylobacter and Salmonella are considered the most frequent bacterial causes of human enteritis in industrialized countries. The consumption of raw or undercooked poultry and pork contaminated meat products are the main sources of human infection. The prevalence of Campylobacter and Salmonella was determined in the present work for extensive production Iberian pig sows, Sus mediterraneus. Samples were co...
