Background: Thermal ablation has been showed to induce immunogenic cell death and enhance the effect of anti-programmed death-1 (PD-1) in preclinical study. The open label phase I/II trial evaluated the safety and efficacy of ablation plus toripalimab (a humanized PD-1 antibody) in patients with advanced hepatocellular carcinoma (HCC). Phase I results on time scheduling, safety and preliminary antitumor activity are reported.
Field studies using the synthetic sex pheromone of Trichophysetis cretacea, a trinary blend of (Z)‐11‐hexadecenyl acetate (Z11‐16:OAc), (Z)‐11‐hexadecenal (Z11‐16:Ald) and (Z)‐11‐hexadecenol (Z11‐16:OH), were performed in Sichuan to determine operational parameters for detection and control, such as dispenser type, blend ratio, dosage, and trap type, height and density. Of three pheromone dispensers tested, grey halo‐butyl isoprene elastomeric septa were significantly more effective than polyvinyl chloride capillary tubing or silicone rubber septa. The ratio of the three components in the blend significantly affected moth catch. In the halo‐butyl isoprene septa, the most effective ratio was 5 : 2 : 1 Z11‐16:OAc:Z11‐16:Ald:Z11‐16:OH. Sticky wing traps caught significantly more moths than water, noctuid moth or cone funnel traps. The most effective height at which wing traps were hung was 20 cm above the jasmine plants. Optimum trap density was 45 traps per hectare. Addition of volatile jasmine compounds did not increase the attractiveness of the sex pheromone. A dosage of 50 μg Z11‐16:OAc per lure was most effective in the autumn weather conditions of Quanwei. These data provide sufficient information to develop effective protocols for using the T. cretacea pheromone to detect and monitor this pest in the jasmine fields.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
