Current clinical framework on nitric oxide role in periodontal disease and bloo...

Objectives: In this review, we explored potential associations between NO and its derivatives, nitrite and nitrate, with periodontal and cardiovascular diseases, with special emphasis on the former. By providing a state-of-the-art and integrative understanding of this topic, we aimed to shed light on the potential role of these three nitrogen oxides in the periodontitis-hypertension nexus, identify knowledge ga...

Nitrite reduction in bacteria : a comprehensive view of nitrite reductases

The last years have witnessed a steady increase of social and political awareness for the need of studying, monitoring, and controlling several anthropological activities that are dramatically impacting the environment and human health. The increasing turnover rates of the nitrogen cycle across the Planet are of major concern, so the understanding of the biological, chemical, and physical processes associated w...

Inhibition-based biosensor for cyanide detection – a preliminary study

Effect of saccharomycin, a natural Saccharomyces cerevisiae biocide, on Hanseni...

Microelectrode Sensor for Real-Time Measurements of Nitrite in the Living Brain...

The impaired blood flow to the brain causes a decrease in the supply of oxygen that can result in cerebral ischemia; if the blood flow is not restored quickly, neuronal injury or death will occur. Under hypoxic conditions, the production of nitric oxide (●NO), via the classical L-arginine-●NO synthase pathway, is reduced, which can compromise ●NO-dependent vasodilation. However, the alternative nitrite (NO2-) r...

Diagnosis of SARS-CoV-2 infection by RT-PCR using specimens other than naso- an...

The rapid and accurate testing of SARS-CoV-2 infection is still crucial to mitigate, and eventually halt, the spread of this disease. Currently, nasopharyngeal swab (NPS) and oropharyngeal swab (OPS) are the recommended standard sampling techniques, yet, these have some limitations such as the complexity of collection. Hence, several other types of specimens that are easier to obtain are being tested as alterna...

Effect of saccharomycin, a natural Saccharomyces cerevisiae biocide, on Hanseni...

ABSTRACT: During spontaneous wine fermentations, most of the non-Saccharomyces yeasts present in grape musts show an early decline in their population. It was traditionally assumed that Saccharomyces cerevisiae (S.c.) prevalence was due to the higher resistance of this species to ethanol. However, wine fermentations performed with single cultures of non-Saccharomyces strains showed that those strains could with...

Characterization of plasmonic effects in AuNP+rGO composite as a sensing layer f...

This work deals with the production of a low-cost disposable biosensor for point of care applications. The proposed sensor is a plasmonic structure based on the Localized Surface Plasmon Resonance (LSPR) interaction of metal nanoparticles (MNPs), embedded into a matrix of reduced Graphene Oxide (rGO). After proper functionalization with selective antibodies (Ab), the efficiency of light extinction is controlled b...
