“…44,45 These two effects have been confirmed and possible pathways proposed for the effects. 46 α-Terpineol has been reported to exhibit antioxidant, antiseptic, anti-hypernociceptive and anti-inflammatory activity 47,48 , and may confer some of these bioactivities on the plant essential oil.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…The enantioselective degradation of the enantiomers might be because of the different spatial structures of the different enantiomers, causing a different distance between the catalytic site of the degrading enzymes and target group of enantiomers to be catalyzed. 26 Nevertheless, the specific mechanism involved needs further research. For example, Wen et al showed that the main reason for the selectivity of Aspergillus niger lipase (ANL, EC 3.1.1.3) to 2,4-dichlorpropmethyl was enzymatic conformation and the binding pattern of 2,4-dichlorprop-methyl to this enzyme.…”

“…Four new iridals with an α-terpineol moiety resulting from cyclization of the homofarnesylside chain, polycycloiridals A–D ( 650 - 653 ), were from the rhizomes of Iris tectorum (Zhang et al, 2015a ). Diterpenoid randainins A–D ( 654 - 657 ) with a trans -fused 7/5 or 5/7 ring system were isolated from leaves and twigs of Callicarpa randaiensis (Nantou, Taiwan, China) (Cheng et al, 2015 ).…”
