Background: Aromatherapy is widely used around the world for stress relief. Whether exposure to essential oil increases the risk of cardiovascular events is still unknown. The purpose of this study was to investigate the effect of essential oil on heart rate and blood pressure among solus por aqua (spa) workers.
Methods: We recruited 100 healthy workers from various spa centres in Taipei, Taiwan. Between July and August of 2010, three repeated measurements - resting heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) - were taken of each spa worker in our study room. Participants were exposed to essential oil vapour generated from an ultrasonic atomizer in the study room for two consecutive hours. The total volatile organic compound (VOC) level in the study room was measured during the study period. We used a linear mixed-effect model to determine the association between the total VOC level and the participants' HR, SBP, and DBP.
Results: For the times from 15 to 60 min after start of exposure, we found that the VOC level was significantly associated with reduced 15-min mean BP and HR. After exposure for more than 1 hour, from 75 to 120 min after start of exposure, we found that the VOC levels were associated with increased 15-min mean BP and HR.
Conclusions: Exposure to essential oil for 1 hour was found to be an effective method of relaxation, as indicated by decreases in the HR and BP. Prolonged exposure for longer than 1 hour to essential oils may be harmful to cardiovascular health among spa workers.

Plant-derived oils provide 20%-35% of dietary calories and are a primary source of essential omega-6 (linoleic) and omega-3 (α-linolenic) fatty acids. While traditional breeding has significantly increased yields in key oilseed crops like soybean, sunflower, canola, peanut, and cottonseed, overall gains have plateaued over the past few decades. Oilseed crops also experience substantial yield losses in both prime and marginal agricultural areas due to biotic and abiotic stresses and shifting agro-climates.

Objectives: This paper describes the design and evaluation of a workshop created to develop safer disaster response strategies for fishing communities, using the 2019 Northeast Brazil Oil Spill as a starting point for community-engaged education.
Methods: The 3-day pilot workshop included presentations, structured discussions, and interactive activities with small-scale fishers (SSFs), university researchers, and representatives of local government agencies. The workshop was evaluated through a mixed-method approach that considered qualitative data from discussion groups, collectively built products, and content retention.

Background: Doxepin (DX) is used orally to relieve itching but can cause side effects like blurred vision, dry mouth, and drowsiness due to its antimuscarinic effect. To reduce these adverse effects and improve skin permeation, DX is being developed in topical formulations. This study aims to improve DX skin absorption by developing a microemulsion (ME) formulation (ME-DX).

The objective of this research is to develop a natural macromolecules-based smart double-layer film using carboxymethyl cellulose (CMC) film containing pomegranate peel anthocyanins (PPA) and cellulose acetate nanofibers (CANFs) with Artemisia sieberi Besser essential oil-loaded nanostructured lipid carriers (ABNLCs). Based on the performance as a color indicator, and other studied properties, the CMC/PPA 8 % film was selected as the optimized film. The double-layer film was constructed by electrospinning the CANFs containing ABNLCs on the optimized CMC film.
