BACKGROUND AND AIMS: Colonoscopy can be painful and uncomfortable. Aromatherapy is often used for the relief of anxiety or discomfort. Recently, it has been reported that olfactory stimulation induces various physiological effects. We investigated the effects of aromatherapy on anxiety and abdominal discomfort during colonoscopy. METHODS: The investigation was carried out using a randomized controlled study. Aromatherapy was performed by vapor diffusion, and each patient was given one of the following treatments: no inhalation (control group), essential-oil-less vapor (vehicle group), lavender oil (lavender group), grapefruit oil (grapefruit group), or Osmanthus fragrans oil (Osmanthus fragrans group)...

The objectives of this study were to develop a new assay for the evaluation of the antimicrobial activities of essential oils (EOs) in vapor-phase and to demonstrate the antimicrobial activities of commercial EOs against BRPs. To achieve the first objective, a microtube cap containing 100 μl of EO was embedded in an agar plate. An agar plug (diameter 13 mm) inoculated with a bacterial suspension containing10(8) CFU ml(-1) was then placed over the cap and incubated at 37 °C for 24 h. Subsequently, bacteria were recovered from the agar plug by immersion in 5 ml of broth for 10 min, followed by vortexing for 30 s, and the broths were then plated for enumeration...

Cixiid planthoppers are considered of major economic importance, as they can transmit phytoplasmas responsible for many plant diseases. While thorougly studied in vineyards, the epidemiology of stolbur phytoplasma, transmitted by Hyalesthes obsoletus Signoret, was rarely investigated on minor crops as lavender, where it leads to 'yellow decline' disease and large economic losses. The objective of this paper is to understand the effect of the local landscape characteristics on the presence and density of H. obsoletus in the 'Plateau de Valensole', southern France...

A sensitive gas chromatographic (GC) GC method has been developed for the determination of diazinon and chlorpyrifos residues in lavender and rosemary leaves. The developed method consists of blending weighed samples of chopped leaves with sodium sulfate as the dehydrating agent, extraction with ethyl acetate, filtration, evaporation with a rotary evaporator, and, finally, capillary GC determination of the pesticides. The recoveries of the method were greater than 90%, and the LOQ was less than 0.1 µg/mL...

Standard raw material test methods such as the ISO Standard 11024 are focused on the identification of lavender oil and not the actual class/quality of the oil. However, the quality of the oil has a significant effect on its price at market. As such, there is a need for raw material tests to identify not only the type of oil but its quality. This paper describes two approaches to rapidly identifying and classifying lavender oil. First, the ISO Standard 11024 test method was evaluated in order to determine its suitability to assess lavender oil quality but due to its targeted and simplistic approach, it has the potential to miss classify oil quality...

Plastics have outgrown most man-made materials and have long been under environmental scrutiny. However, robust global information, particularly about their end-of-life fate, is lacking. By identifying and synthesizing dispersed data on production, use, and end-of-life management of polymer resins, synthetic fibers, and additives, we present the first global analysis of all mass-produced plastics ever manufactured. We estimate that 8300 million metric tons (Mt) as of virgin plastics have been produced to date...

A research team that works on scholarship related to sexual minority issues has been conducting research and recruiting participants since the fall of 2012. In the years since the team was formed, there has been a variety of challenges with recruitment, approval for research through the Institutional Review Board, gaining access to the lesbian, gay, bisexual, and queer (LGBQ) community, and general mistrust of researchers. Using concepts from feminist-informed qualitative research methodology-including reflexivity, positionality, and engaging in research with individuals from marginalized communities-we present reflections on some of the methodological challenges the research team has encountered while trying to conduct LGBQ research in southwest Virginia...

Disruptive vocalization and resisting personal care is a problem for staff in most skilled nursing facilities. Often these behaviors result in the resident being treated with antipsychotics. The Namaste Care program which takes place in a calm environment and offers a loving touch approach to care, has been successful in eliminating these behaviors. The room or space where Namaste Care takes place is as free from disruption as possible and as the resident is welcomed into the room, the calming music and scent of lavender surrounds them...
