We have developed two methods for studying effects of visual cues on behavior in the absence of tactile and chemical cues. One method involves videotaping responses of crayfish to reflective walls in an aquarium; the other examines effects of visual inputs provided by a live crayfish behind a transparent partition.
In this report we demonstrate techniques that can be used to investigate the biology of the crayfish hindgut. We show how to dissect a crayfish abdomen and study the associated anatomy, physiology and modulation of activity. The peristaltic activity and strength of contractions are measured using a force transducer.
We have synthesized a novel analogue of pancratistatin with comparable anti-cancer activity as native pancratistatin; interestingly, combinatory treatment with tamoxifen yielded a drastic enhancement in apoptotic and autophagic induction by mitochondrial targeting with minimal effect on noncancerous fibroblasts. Thus, JCTH-4 in combination with tamoxifen could provide a safe anti-cancer therapy.
This paper describes how to implement a battery of behavioral tasks to examine emotion recognition of isolated facial and vocal emotion expressions, and a novel task using commercial television and film clips to assess multimodal emotion recognition that includes contextual cues.
This paper instructs users of in vivo micro-computed tomography (µCT) scanners how to anesthetize, correctly position and restrain the hind limb of a rat for minimal movement during high-resolution imaging of the tibia. The result is high quality images that can be processed to accurately quantify bone micro-architecture.
