This study aimed to evaluate the subacute effect of two types Ag-NPs(EG-AgNPs and PVP-EG-AgNPs) on antioxidant/pro-oxidant balance in rats. Seventy Wistar rats (35 males 35 females) were divided 7 groups intraperitoneally exposed for 28 days 0, 1, 2 4 mg/kg bw/day EG-Ag-NPs PVP- EG-Ag-NPs. After days, blood was collected, total antioxidant capacity (TAC), thiobarbituric reactive species (TBARS),protein carbonyl (PROTC) levels, reduced glutathione (GSH) levels catalase (CAT) activity...
Polyethylene terephthalate (PET) is a major pollutant polymer, due to its wide use in food packaging and fiber production industries worldwide. Currently, there great interest for recycling the huge amount of PET-based materials, derived especially from textile industries. In this study, we applied electrospinning technique obtain nanostructured fibrillary membranes based on PET materials. Subsequently, recycled networks were decorated with silver nanoparticles through chemical reduction...
Injuries and diseases of the skin require accurate treatment using nontoxic noninvasive biomaterials, which aim to mimic natural structures body. There is a strong need develop biodevices capable accommodating nutrients bioactive molecules generating process vascularization. Electrospinning robust technique, as it can form fibrous for tissue engineering wound dressings. The best way forming such meshes healing choose two polymers that complement each other regarding their properties. On one...
The production of highly porous and three-dimensional (3D) scaffolds with biomimicking abilities has gained extensive attention in recent years for tissue engineering (TE) applications. Considering the attractive versatile biomedical functionality silica (SiO2) nanomaterials, we propose herein development validation SiO2-based 3D TE. This is first report on fibrous architectures, using tetraethyl orthosilicate (TEOS) polyvinyl alcohol (PVA) during self-assembly electrospinning (ES)...
Hydroxyapatite (HAp) and bacterial cellulose (BC) composite materials represent a promising approach for tissue engineering due to their excellent biocompatibility bioactivity. This paper presents the synthesis characterization of two types based on HAp BC, with antibacterial properties provided by silver nanoparticles (AgNPs). The were obtained following routes: (1) was in situ directly BC matrix containing different amounts AgNPs coprecipitation method, (2) first separately using then...
The highest amount of the world's polyethylene terephthalate (PET) is designated for fiber production (more than 60%) and food packaging (30%) it one major polluting polymers. Although there a great interest in recycling PET-based materials, large unrecycled material derived mostly from textile industries. aim this study was to obtain characterize nanostructured membranes with fibrillar consistency based on recycled PET nanoparticles (Fe3O4@UA) using electrospinning technique. obtained...
Polyethylene terephthalate (PET) is a widely utilized synthetic polymer, favored in various applications for its desirable physicochemical characteristics and widespread accessibility. However, extensive utilization, coupled with improper waste disposal, has led to the alarming pollution of environment. Thus, recycling PET products essential diminishing global turning into meaningful materials. Therefore, this study proposes fabrication electrospun membranes made recycled nanofibers as...
With the growing interest in nanofibers and urgent need to address environmental concerns associated with plastic waste, there is an increasing focus on using recycled materials develop advanced healthcare solutions. This study explores potential of poly(ethylene terephthalate) (PET) nanofibers, functionalized copper-enhanced alginate, for applications wound dressings. Nanofibers desirable antimicrobial properties were developed chemical recycling electrospinning techniques, offering a...
Interest to finding a solution help reduce the cases of microbial infections in wounds is very high. The concern all greater as antibiotic resistance has become an increasingly common problem. In order find new way synthesize wound dressing which superior prop-er-ties, sodium alginate, hyaluronic acid and silk fibroin functionalized with zinc oxide clove oregano essential oils were used. results are encouraging for using this kind efficient treatment, showing antibacterial activity against...
The aim of this study was to obtain biocompatible coatings based on polylactic acid, hydroxyapatite and nanostructured Cefepime-functionalized magnetite for enhancing the activity next-generation implants against antibiotic-resistant pathogens. Mixtures various ratios (Fe3O4@CEF, HAP/Fe3O4@CEF PLA/Fe3O4@CEF) were obtained deposited glass slides by Matrix Assisted Pulsed Laser Evaporation (MAPLE). in vitro biological effects these coated surfaces murine normal osteoblasts (MC3T3-E1 Subclone 4...
The main objective of the study was to produce alternative binder materials, obtained with low cost, energy consumption, and CO2 production, by regenerating end-of-life (EOL) materials from mineral deposits, replace ordinary Portland cement (OPC). analyzed were ash slag Turceni thermal power plant deposit, Romania. These initially examined for morphology, mineralogical composition, elemental degree crystallinity, heating behavior, determine their ability be used as a potential source...
It is already well known that the tissue–implant interface one of most critical factors for success implant integration. The use bioactive and biomimetic surfaces great interest in biomedical applications, especially tissue engineering. Therefore, our study, we aimed to obtain successful coatings based on hydroxyapatite, antibiotics growth order increase biocompatibility commercial materials by promoting cell attachment without toxic effects, as inhibition microbial biofilm formation. In...
