Essential oil of oregano (Origanum vulgare L.) reduces infection and proliferation of Toxoplasma gondii in BeWo cells with induction of autophagy and death of tachyzoites through a mechanism similar to necrosis
This study was to assess the toxicity of OEO on BeWo cells and T. gondii tachyzoites, as well as to evaluate its effectiveness in in vitro infection models and determine its direct action on free tachyzoites. OEO toxicity on BeWo cells and T. gondii tachyzoites was assessed by MTT and trypan blue methods, determining cytotoxic concentration (CC50), inhibitory concentration (IC50), and selectivity index (SI). Infection and proliferation indices were analyzed. Direct assessments of the parasite included reactive oxygen species (ROS) levels, mitochondrial membrane potential, necrosis, and apoptosis, as well as electron micros...

Pickering Emulsion Edible Film Loaded With Oregano Essential Oil and Application in Muffin Preservation
A functional edible film containing Pickering emulsion loaded with oregano essential oil was developed. The sustained release of OEO in muffins significantly delayed muffin decay at 25 °C (p <  0.05). ABSTRACTA functional edible film containing Pickering emulsion (PE) loaded with oregano essential oil (OEO) was developed. The sustained release of OEO in muffins significantly delayed muffin decay at 25 °C (p <  0.05). According to the influence of oxygen permeability, antibacterial activity and mechanical properties of the active film, the optimum preparation conditions of PE were determined by orthogonal ex...

Effects of natural treatments on the varroa mite infestation levels and overall health of honey bee ( < i > Apis mellifera < /i > ) colonies
by Laura Narciso, Martina Topini, Sonia Ferraiuolo, Giovanni Ianiro, Cinzia Marianelli The survival of the honey bee (Apis mellifera), which has a crucial role in pollination and ecosystem maintenance, is threatened by many pathogens, including parasites, bacteria, fungi and viruses. The ectoparasiteVarroa destructor is considered the major cause of the worldwide decline in honey bee colony health. Although several synthetic acaricides are available to control Varroa infestations, resistant mites and side effects on bees have been documented. The development of natural alternatives for mite control is therefore encouraged...

Incorporation of essential oils in polymeric films for biomedical applications
This article aims to discuss updates over the last 10 years on incorporating EOs into natural and synthetic biodegradable polymer films for biomedical applications. Chitosan, alginates, cellulose, and proteins such as gelatine, silk, and zein are among the natural polymers most commonly used to prepare biodegradable films for release EOs. In addition to these, the most cited synthetic biodegradable polymers are poly(L-lactide) (PLA), poly(vinyl alcohol) (PVA), and poly(ε-caprolactone) (PCL). The EOs of clove, cinnamon, tea tree, eucalyptus, frankincense, lavender, thyme and oregano incorporated into polymeric films have b...

Combining the pharmaceutical and toxicological properties of select essential oils with their chemical components by GC-MS analysis
Chem Biodivers. 2024 May 2:e202400738. doi: 10.1002/cbdv.202400738. Online ahead of print.ABSTRACTIn the current investigation, a comprehensive analysis was carried out on essential oils (Eos) extracted from six aromatic plant species, namely Rosmarinus officinalis, Pelargonium graveolens, Thymus vulgaris, Origanum vulgare, Laurus nobilis, and Aloysia citrodora. An exploration was conducted into the chemical composition using Gas Chromatography-Mass Spectrometry (GC/MS), antioxidant properties assessed through DPPH, ABTS, CUPRAC, FRAP, MCA, and PBD assays, ecotoxicological impacts evaluated via allelopathy and the Daphnia ...

Development of Antifungal Packaging From Low ‐Density Polyethylene With Essential Oil of Oregano and Potassium Sorbate
Antifungal low-density polyethylene films were formulated with oregano essential oil. Oregano essential oil modifies the physical properties of low-density polyethylene films. Potassium sorbate influences the barrier properties of low-density polyethylene films. ABSTRACTAntimicrobial low-density polyethylene (LDPE) films were developed by adding 0%, 0.5%, 1.0%, 2.5% and 5.0% (w/w) of Mexican oregano essential oil (OEO) or potassium sorbate (PS) as a positive antifungal control to inhibit the growth ofPenicillium expansum,Penicillium citrinum andAspergillus niger in  vitro. Three methods of adding OEO in LDPE were evaluate...

Green manure (Crotalaria juncea L.) enhances Origanum vulgare L. biomass accumulation, essential oil yield, and phytochemical properties
The objectives of this study were to evaluate the GM on biomass, essential oil (EO), phenolic and antioxidant. The experiment consisted: control; 150, 300, 450, and 600 g (Sh= leaves+steam) more 200 g roots (R); 600 g aerial part; 200 g roots; and soil with 300 g cattle manure per pot. The highest dry weights were observed in the presence of GM and cattle manure (90 days). The control had an EO production 75% lower in relation to the dose of 450 g GM (Sh+R). Principal component analysis showed that GM and cattle manure positively influenced the dry weight, content, yield, and EO constituents, and total flavonoids. The GM c...
