The perception of intense bitterness is associated with disgust and food rejection. The present cross-modal event-related potential (ERP) study investigated whether a bitter aftertaste is able to influence affective ratings and the neuronal processing of visual food cues. We presented 39 healthy normal-weight women (mean age: 22.5 years) with images depicting high-caloric meat dishes, high-caloric sweets, and low-caloric vegetables after they had either rinsed their mouth with wormwood tea (bitter group; n = 20) or water (control group; n = 19) for 30s...

Leishmaniasis is one of the most neglected human diseases with an estimated global burden ranking second in mortality and fourth in morbidity among the tropical infections. Chemotherapy involving the use of drugs like glucantime is the mainstay treatment in endemic areas of Iran. Drug resistance is increasingly prevalent, so search for alternative therapy is gathering pace. Medicinal herbs, like wormwood Artemisia, have chemical compounds effective against a number of pathogens. In this study, the efficacy of ethanol extract from Artemisia absinthium (Asteraceae) against Leishmania major L...

There is a continual need to develop novel and effective melanogenesis inhibitors for the prevention of hyperpigmentation disorders. The plant Artemisia capillaris Thunberg (Oriental Wormwood) was screened for antipigmentation activity using murine cultured cells (B16-F10 malignant melanocytes). Activity-based fractionation using HPLC and NMR analyses identified the compound 4,5-O-dicaffeoylquinic acid as an active component in this plant. 4,5-O-Dicaffeoylquinic acid significantly reduced melanin synthesis and tyrosinase activity in a dose-dependent manner in the melanocytes...

The concentrations of α/β-thujone and the bitter components of Artemisia absinthium were quantified from alcoholic wormwood extracts during four phenological stages of their harvest period. A solid-phase micro-extraction method coupled to gas chromatography-mass spectrometry was used to determine the concentration of the two isomeric forms of thujone. In parallel, the combination of ultra-high pressure liquid chromatography and high resolution mass spectrometry allowed to quantify the compounds absinthin, artemisetin and dihydro-epi-deoxyarteannuin B...

Herbs and traditional medicines have been applied for thousands of years, but researchers started to study their mode of action at the molecular, cellular and tissue levels only recently. Nowadays, just like in ancient times, natural compounds are still determining factors in remedies. To support this statement, the recently won Nobel Prize for an anti-malaria agent from the plant sweet wormwood, which had been used to effectively treat the disease, could be mentioned. Among natural compounds and traditional Chinese medicines, the green tea polyphenol epigallocatechin gallate (EGCg) is one of the most studied active substances...

OBJECTIVE: To find and analyze descriptions in ancient Greek and Roman literature that reveal what was known at the time about seasickness. METHODS: A systematic search was made in the original literature beginning in the Greek period with Homer in ca 800 bc and extending up to Aetios Amidenos in the late Roman period in ca 600 ad. RESULTS: Rough seas and unpleasant odors were recognized as the major triggers; susceptibility was greater in persons not adapted to sea travel, of a labile mental state, or with anxiety; nausea, emesis, vertigo, anorexia, faintness, apathy, headache, and impending doom were frequently reported symptoms...

To respond adaptively to change organisms must utilize information about recent events and environmental context to select actions that are likely to produce favorable outcomes. We developed a dynamic delayed nonmatching to position task to study the influence of spatial context on event-related activity of medial prefrontal cortex neurons during reinforcement-guided decision-making. We found neurons with responses related to preparation, movement, lever press responses, reinforcement, and memory delays. Combined event-related and video tracking analyses revealed variability in spatial tuning of neurons with similar event-related activity...

Absinthe is a strong spirit beverage, mostly green in color, containing besides ethyl alcohol (main component), alcoholic macerate of wormwood and other plants such as star anise and fennel seed. Due to the potential risks associated with the presence of α- and β-thujone many countries have implemented strict rules limiting the content of these congeners in alcohol products. The presented paper describes a simple and sensitive method for the determination of α- and β-thujone in human serum using Solid Phase Extraction as a sample preparation method combined with GC/MS analysis...

Thujone is a monoterpene ketone natural substance found mainly in wormwood and sage. Previous studies have shown that Thujone has various pharmacological effects, such as anti-tumor, analgesic, and insecticide. The effect of α-Thujone to human immune cells is still unknown. Our study focuses on investigating the effects and mechanism of α-Thujone to CD3AK (anti- CD3 antibody induced activated killer) cells proliferation and cytotoxicity to colon cancer cell lines. With cell proliferation and FCM assay, it is found that α-Thujone could significantly enhance CD3AK cell proliferation and expression of CD107a in a dose-dependent manner...

The Powder River Basin in Wyoming and Montana contains the United States' largest coal reserve. The area produces large amounts of natural gas through extraction from water-saturated coalbeds. Determining the impacts of coalbed natural gas-produced efflux water on crops is important when considering its potential use as supplemental irrigation water. We hypothesized that coalbed natural gas water, because of its high salinity and sodicity, would affect plant secondary metabolism (essential oils) and biomass accumulation...

Wormwoods (Artemisia species) from the génépi group are, along with Edelweiss, iconic plants of the Alpine region and true symbols of inaccessibility because of their rarity and their habitat, largely limited to moraines of glaciers and rock crevices. Infusions and liqueurs prepared from génépis have always enjoyed a panacea status in folk medicine, especially as thermogenic agents and remedies for fatigue, dyspepsia, and airway infections. In the wake of the successful cultivation of white génépi (Artemisia umbelliformis Lam...

Artemisinin, a sesquiterpene lactone isolated from Artemisia annua L. (sweet wormwood), is extensively used in the treatment of malaria. In order to better understand the metabolism of terpenes in Artemisia annua and the influence of terpene synthases on artemisinin yield, the expression pattern of a monoterpene alcohol dehydrogenase (ADH2) has been studied using transgenic plants expressing promoter-GUS fusion. ADH2 played a major role in monoterpenoid biosynthesis including carveol, borneol and artemisia ketone through in vitro biochemical analysis...

In the last decades, prevalence of autism spectrum disorder (ASD) has been on the rise. However, clear aetiology is still elusive and improvements in early diagnosis are needed. To uncover possible biomarkers present in ASD, we used two-dimensional polyacrylamide gel electrophoresis and nanoliquid chromatography-tandem mass spectrometry (nanoLC-MS/MS), to compare salivary proteome profiling of children with ASD and controls. A total of 889 spots were compared and only those spots with a fold change ≥1.7 and a P-value <0...
