Recent research on visceral perception has indicated that hemispheric specialization and emotionality may account for individual differences among subjects. The present study was designed to examine the nature of the relationship between hemispheric specialization and emotionality, and the manner in which these variables influence individual differences in visceral perception (i.e., detection of cardiac activity). Male subjects were given 20 questions used to test lateral eye movements. Following the completion of the State‐Trait Anxiety Inventory (STAI), Form X‐1 (State Anxiety), cardiac awareness was assessed using the Whitehead heartbeat discrimination procedure. Subjects then completed the STAI, Form X‐2 (Trait Anxiety), and the Eysenck Personality Inventory. Results indicated that good heartbeat perceivers made significantly more left lateral eye movements (i.e., right hemisphere preferent) than poor perceivers on any of the emotional indicators. It was found, however, that subjects with high scores on two of the three emotional indicators made significantly more left lateral eye movements than subjects with low scores. Additional analyses indicate that respiration rate and subject obesity may affect the ability to detect feedback of cardiovascular function.
Frozen samples of Antarctic krill (Euphausia superba Dana) were found to contain 71 -4% moisture, and on a dry matter basis 24.6% lipid, 49% protein (N x 6-25), 2.5% chitin, and 9.8% ash. Fatty acids from the crude lipid fraction were made up of 43 -8 % saturated, 32.8 % mono-unsaturated, and 23 * 4 % polyunsaturated types.Krill protein concentrate prepared as a light, fresflowing powder by isopropanol extraction of krill contained 74.3 % crude protein, 15.4 % ash, 6 % chitin and 0.3 % lipid, and was rich in lysine, arginine, tryptophan, and threonine. The protein efficiency ratio of this concentrate was found to be the same as that of casein. The significance of these results in relation to those obtained for other fish protein concentrates is discussed.
Glycolysis in rock lobster comprising the oblique extensor, oblique flexor and enveloping muscles of Jasus novae-hollandiae was studied under anaerobic conditions at ZOO, 15" and 0°C. After bisecting the muscles along the mediosaggital plane one section was treated by dipping for 4 min in 3% sodiumThe following abbreviations are used in this paper: ATP, adenosine 5'-triphosphate; ADP, adenosine 5'4-phosphate; PEP, phosphoenolpyruvate; NAD+ and NADH, oxidized and reduced forms of nictotinamide-adenine dinudeotide; Go, increase in rate constant for a IO-degree Celsius change in temperature.
A taint resembling kerosene is sometimes present in mullet (Mugil cephalus) caught near Brisbane, Australia. It is not thought to be the same as the ‘petroleum’ taint sometimes found in cod and salmon which is caused by the thermal decomposition of dimethyl‐β‐propiothetin to dimethyl sulphide. The ‘kerosene’ taint is removed from the body tissue of mullet by solvent extraction and is associated with the hydrocarbon fraction of the extract. Tainted fish differ from untainted fish in that they have fatinfiltrated livers, a higher lipid content in fillets and a different fatty acid composition of both fillets and livers.
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.
