Production of polyhydroxybutyrate (PHB) and factors impacting its chemical and mechanical characteristics
(MDPI, 2020-12-04)Plastic pollution is fueling the grave environmental threats currently facing humans, the animal kingdom, and the planet. The pursuit of renewable resourced biodegradable materials commenced in the 1970s with the need for ... -
β-glucan metabolic and immunomodulatory properties and potential for clinical application
(MDPI, 2020-12-10)β-glucans are complex polysaccharides that are found in several plants and foods, including mushrooms. β-glucans display an array of potentially therapeutic properties. β-glucans have metabolic and gastro-intestinal effects, ... -
A bilayer vaginal tablet for the localized delivery of disulfiram and 5-fluorouracil to the cervix
(MDPI, 2020-12-06)This study was performed to develop an adjuvant therapy in the form of a self-administered vaginal tablet regimen for the localized delivery of chemotherapeutic drugs. This therapy will help to reduce relapse by eradicating ... -
Characterisation and in vivo evaluation of Araucaria angustifolia pinhão seed coat nanosuspension as a functional food source
(Royal Society of Chemistry, 2020-10-08)Araucaria angustifolia seeds are culturally important from South America; however, the seed coat is generally discarded and have yet to find a beneficial commercial impact. We propose a new formulation to the usage of ... -
Yerba mate extract in microfibrillated cellulose and corn starch films as a potential wound healing bandage
(MDPI, 2020-11-27)Microfibrillated cellulose films have been gathering considerable attention due to their high mechanical properties and cheap cost. Additionally, it is possible to include compounds within the fibrillated structure in ... -
Biodegradation and antimicrobial properties of zinc oxide-polymer composite materials for urinary stent applications
(MDPI, 2020-10-20)Research advancements in the field of urinary stents have mainly been in the selection of materials and coatings to address commonly faced problems of encrustation and bacterial adhesion. In this study, polylactic acid ... -
Purified β‐glucans from the Shiitake mushroom ameliorates antibiotic‐resistant Klebsiella pneumoniae‐induced pulmonary sepsis
(Society for Applied Microbiology, 2020-07-24)Bacterial infection remains the main cause of acute respiratory distress syndrome and is a leading cause of death and disability in critically ill patients. Here we report on the use of purified β‐glucan (lentinan) extracts ... -
Effect of stereolithography 3D printing on the properties of PEGDMA hydrogels.
