The aim of our study was to examine the potential ameliorating effect of the methanolic extract of Satureja hortensis L. (summer savory) aerial parts against cisplatin-induced oxidative damage in renal, hepatic, and testicular tissues. S. hortensis methanol extract at the doses of 50, 100 and 200 mg/kg of body weight were orally administered to Wistar rats once daily for 10 days. Toxicity was induced by intraperitoneal injection of a single dose of cisplatin (7.5 mg/kg of body weight) on the 5th day of the experiment. Applied treatment with S. hortensis extract restored tissue morphology, ameliorated levels of serum parameters for liver, renal and testes function, tissue oxidative stress parameters, and increased Bcl-2/Bax ratio as an indicator of apoptosis in experimental animals caused by application of cisplatin. UHPLC/DAD/HESI-MS/MS analysis revealed that S. hortensis extract was rich in phenolic compounds with rosmarinic acid (24.9 mg/g) as the main compound, followed by caffeic acid (1.28 mg/g) and naringenin (1.06 mg/g). Our findings suggest that S. hortensis may be a valuable source of dietary and pharmacologically important phenolic compounds, especially rosmarinic acid, in pharmaceutical and functional food formulations in order to maintain normal health conditions or as a remedy in various diseases caused by oxidative damage.

Article Synopsis
- The study investigates the presence of West Nile virus (WNV) in mosquitoes in Hamedan, Iran, where the virus is known to circulate but its mosquito vectors are not fully understood.
- Researchers collected a total of 3,243 mosquitoes from different habitats and identified seven WNV-positive pools, mainly in the species Culiseta longiareolata and Culex hortensis, indicating that WNV is actively circulating in the area.
- The findings highlight the need for further research on local WNV transmission dynamics and vector variations across different regions in Iran, providing essential information to shape prevention strategies.

The ethnopharmacological relevance of the () flower's aqueous extract lies in its traditional use as a herbal remedy in Southeast Asia. With a rich history in folk medicine, this aqueous has been esteemed for its purported sedative and anxiolytic properties. Our research delves into the scientific basis of these traditional claims, exploring the potential mechanisms underlying the observed effects of flower's aqueous extract on sleep promotion and mood regulation.

The use of direct injection ion mobility mass spectrometry (DI-IM-MS) to detect and identify betacyanin pigments in A. hortensis 'rubra' extracts was explored for the first time, with results compared to conventional LC-MS/MS analysis. The anti-inflammatory activities of leaf and seed extracts, alongside purified amaranthin and celosianin pigments, were investigated using a model of lipopolysaccharide (LPS)-activated murine macrophages.

In the circular economy framework, hydrosols, by-products of the essential oil industry, are gaining attention for their potential in waste reduction and resource reuse. This study analyzed hydrosols from six edible flowers, investigating their chemical composition (VOC-Hyd) and antibacterial properties alongside volatile organic compounds of fresh flowers (VOC-Fs) and essential oils (EOs). exhibited ketones as major VOC-Fs (62.
