Aromatherapy and plant-based essential oils are widely used as complementary and alternative therapies for symptoms including anxiety. Furthermore, it was reportedly effective for the care of several diseases such as Alzheimer's disease and depressive illness. To investigate the pharmacological effects of essential oils, we developed an in vitro assay system using immortalized hypothalamic neuronal cells (GT1-7 cells). In this study, we evaluated the effects of essential oils on neuronal death induced by hydrogen peroxide (H2O2), aluminum, zinc, or the antagonist of estrogen receptor (tamoxifen). Among tests of various essential oils, we found that H2O2-induced neuronal death was attenuated by the essential oils of damask rose, eucalyptus, fennel, geranium, ginger, kabosu, mandarin, myrrh, and neroli. Damask rose oil had protective effects against aluminum-induced neurotoxicity, while geranium and rosemary oil showed protective activity against zinc-induced neurotoxicity. In contrast, geranium oil and ginger oil enhanced the neurotoxicity of tamoxifen. Our in vitro assay system could be useful for the neuropharmacological and endocrine pharmacological studies of essential oils.

Duchenne muscular dystrophy is a neuromuscular disease with an overall incidence of between 1 in 5,000 newborn males. Carriers may manifest progressive muscle weakness, resulting from the progressive degeneration of skeletal muscles, generating cardiac and respiratory disorders. Considering the lack of effective treatments, different therapeutic approaches have been developed, such as protein synthesis and extracellular matrix derivatives that can be used to improve muscle regeneration, maintenance, or repair.

Parkinson's Disease (PD) is a neurodegenerative disorder characterized by the pro-gressive loss of dopaminergic neurons in the substantia nigra, leading to motor dysfunction and non-motor symptoms. Current treatments primarily offer symptomatic relief without halt-ing disease progression. This has driven the exploration of natural compounds with neuropro-tective properties.

Pyomelanogenic P. aeruginosa, frequently isolated from patients with urinary tract infections and cystic fibrosis, possesses the ability to withstand oxidative stress, contributing to virulence and resulting in persistent infections. Whole genome sequence analysis of U804, a pyomelanogenic, multidrug-resistant, clinical isolate, demonstrates the mechanism underlying pyomelanin overproduction.

The extraction of plant essential oils (EOs) and analysis by gas chromatography coupled to mass spectrometry (GC-MS) are standard methods when studying aromatic plants and the chemical composition of EOs. Here, two simple methods for the extraction of EO compounds from leaves of Thymus vulgaris are described. Organic solvent extraction and solid-phase microextraction (SPME), respectively, are used and the results of the GC-MS analyses are compared.

Ash gourd (Benincasa hispida) is cultivated for its medicinal benefits, with processing enhancing its health properties and shelf life. The processing industries generate significant byproducts, with peel and seeds common across all methods, along with lime (from petha sweet production), brine wastewater (from fermented foods), and pulp from juice processing. This review focuses on peel, seeds, and lime wastewater, which contain valuable compounds like polyphenols, terpenoids, essential oils, and ribosome-inactivating proteins known for their antioxidant and antibacterial properties.
