Microvascular, biochemical, and clinical impact of hyperbaric oxygen therapy in...

Background: Diabetic foot ulcers (DFUs) are a serious complication of diabetes and are often difficult to treat. Hyperbaric oxygen therapy (HBOT) has been proposed as an adjunctive treatment to promote healing, but its long-term clinical and biological effects remain insufficiently characterized. This study aimed to evaluate the impact of HBOT on systemic biomarkers, local microvasculature, and clinical outcome...

Grape stems as sources of tryptophan and selenium: functional properties and an...

The Douro Demarcated Region's winery industry produces million tonnes of by-products annually, making their reuse essential to minimize environmental impact. Grape stems, rich in bioactive compounds and nutrients, have demonstrated potential health benefits. This study analysed four red grape stems from the Douro region to assess their nutritional value and potential health benefit. Tryptophan, selenium, and ph...

Phytochemical and biotechnological valorisation of winery by-products for prost...

Harvesting the power of green synthesis: gold nanoparticles tailored for prosta...

Biosynthetic gold nanoparticles (bAuNPs) present a promising avenue for enhancing biocompatibility and offering an economically and environmentally responsible alternative to traditional production methods, achieved through a reduction in the use of hazardous chemicals. While the potential of bAuNPs as anticancer agents has been explored, there is a limited body of research focusing on the crucial physicochemic...

Exploring the potential protective effect of probiotics in obesity-induced colo...

Colorectal cancer (CRC) is the third most common cancer diagnosed today and the third leading cause of death among cancer types. CRC is one of the gastrointestinal tumors with obesity as the main extrinsic risk factor, since, according to authors, the meta-inflammation sustained by the excess adipose tissue can provide abundant circulating lipids, as well as hormones and metabolites crucial to tumor development...

On risk analysis of the use of Cannabinoids compounds as therapy in Dementia

Nowadays dementia pharmaceutical treatment has an unfavourable risk-benefit relation. New therapeutic approaches’ adoption is need due to the high prevalence of this condition. To evaluate the risk of using cannabinoids compounds as nonharmful therapeutic approach in dementia. A systematic literature review based on PRISMA was performed. PubMed and Clinical Trials database were used to collect articles between ...

Radiotherapy metastatic prostate cancer cell lines treated with gold nanorods m...

MicroRNA (miRNA) modulation has been identified as a promising strategy for improving the response of human prostate cancer (PCa) to radiotherapy (RT). Studies have shown that mimics or inhibitors of miRNAs could modulate the sensitivity of PCa cells to RT. In addition, pegylated gold nanoparticles have been studied as a therapeutic approach to treat PCa cells and/or vehicles for carrying miRNAs to the inside o...

Metabolic Disruption of Gold Nanospheres, Nanostars and Nanorods in Human Metas...

Nanomaterials offer a broad spectrum of applications in biomedicine. The shapes of gold nanoparticles could modulate tumor cell behavior. Spherical (AuNPsp), stars (AuNPst) and rods (AuNPr) shapes of polyethylene glycol coated-gold nanoparticles (AuNPs-PEG) were synthesized. Metabolic activity, cellular proliferation, and reactive oxygen species (ROS) were measured and the impact of AuNPs-PEG in metabolic enzym...

Application of Gold Nanoparticles as Radiosensitizer for Metastatic Prostate Ca...

More than 50% of all prostate cancer (PCa) patients are treated by radiotherapy (RT). Radioresistance and cancer recurrence are two consequences of the therapy and are related to dose heterogeneity and non-selectivity between normal and tumoral cells. Gold nanoparticles (AuNPs) could be used as potential radiosensitizers to overcome these therapeutic limitations of RT. This study assessed the biological interac...

The magic cocktail: ampicillin and biosynthesized gold nanoparticles synergism ...

Gold nanoparticles (AuNPs) have garnered attention as a potential alternative to conventional antibiotics due to their innovative antibacterial properties. This study demonstrates the successful production of biosynthetic gold nanoparticles (bAuNPs) using Pseudomonas aeruginosa (P. aeruginosa) as spherical nanostructures at 58 °C for 24 h, under alkaline pH (9.0). The successful synthesis of bAuNPs was confirme...
