Phytotherapeutic Hierarchical PCL-Based Scaffolds as a Multifunctional Wound Dressing: Combining 3D Printing and Electrospinning.

This study focuses on developing hybrid scaffolds incorporating phytotherapeutic agents via a combination of three-dimensional (3D) printing and electrospinning to enhance mechanical properties and provide antibacterial activity, in order to address the limitations of traditional antibiotics. In this regard, 3D-printed polycaprolactone (PCL) struts are first fabricated using fused deposition modeling (FDM). Then, alkaline surface treatment is applied to improve the adhesion of electrospun nanofibers.

Antibacterial and antioxidant activity of cinnamon essential oil-laden 45S5 bioactive glass/soy protein composite scaffolds for the treatment of bone infections and oxidative stress.

This study aimed to fabricate cinnamon essential oil (CO)-laden 45S5 bioactive glass (BG)/soy protein (SP) scaffolds exhibiting antioxidant and antibacterial activity. In this regard, 45S5 BG-based scaffolds were produced by the foam replica method, and subsequently the scaffolds were coated with various concentrations of CO (2.5, 5 and 7 (v/v) %) incorporated SP solution.

Sesquiterpenes and sesquiterpenoids harbor modulatory allosteric potential and affect inhibitory GABA receptor function in vitro.

Naturally occurring compounds such as sesquiterpenes and sesquiterpenoids (SQTs) have been shown to modulate GABA receptors (GABA Rs). In this study, the modulatory potential of 11 SQTs at GABA Rs was analyzed to characterize their potential neurotropic activity. Transfected HEK293 cells and primary hippocampal neurons were functionally investigated using electrophysiological whole-cell recordings.

Isolation of sesquiterpenoids from Matricaria chamomilla by means of solvent assisted flavor evaporation and centrifugal partition chromatography.

The (semi)volatile fraction of Matricaria chamomilla L., an annual herbal plant from the family of Asteraceae, contains high quantities of sesquiterpenes and sesquiterpenoids. A method was developed to achieve isolation and separation of these compounds, using a combination of solvent assisted flavor evaporation (SAFE) and solid support-free liquid-liquid chromatography.

Physical and Antibacterial Properties of Peppermint Essential Oil Loaded Poly (-caprolactone) (PCL) Electrospun Fiber Mats for Wound Healing.

The aim of this study was to fabricate and characterize various concentrations of peppermint essential oil (PEP) loaded on poly(ε-caprolactone) (PCL) electrospun fiber mats for healing applications, where PEP was intended to impart antibacterial activity to the fibers. SEM images illustrated that the morphology of all electrospun fiber mats was smooth, uniform, and bead-free. The average fiber diameter was reduced by the addition of PEP from 1.
