The influences of moderate intensity exercise and a meal postexercise on heart rate and metabolic substrates were studied， Eight college students. who had not been engaged in regular endurance training. participated in this study. They exercised on a bicycle ergometer for 30 min at 60% of their maximum V02. They were given a meal(500 kcal) and water 3 hours after cessation of the exercise. The heart rate was monitored continuously. Blood level of glucose and lactate and serum level of glycerol and non esterified fatty acid(NEFA) were measured before. during and following the exercise at selected time points. Heart rate was elevated during the exercise from preexercise control value. It remained elevated as compared with the control value in postexercise period of 6 hours long. The meal postexercise caused the elevation of heart rate. The lactate increased during the exercise and returned to the control value by 3 hours postexercise. The glucose was not affected by the exercise but was elevated by the meal, the elevation lasting for 2 hours. The NEFA increased during the exercise and it was kept elevated during the postexercise period until the meal was taken. The exercise induced an increase in glycerol. The glycerol leveln returned to the control value by the time point for the meal. The results suggest that the exercise with the intensity of 60% VO2 max. enhances overall postexercise metabolism for at least 6 hours. The results also suggest that the meal switches postexercise metabolism toward predominence of carbohydrate metabolism

Characterization of active miniature inverted-repeat transposable elements in the peanut genome

Miniature inverted-repeat transposable elements (MITEs), some of which are known as active non-autonomous DNA transposons, are found in the genomes of plants and animals. In peanut (Arachis hypogaea), AhMITE1 has been identified in a gene for fatty-acid desaturase, and possessed excision activity. However, the AhMITE1 distribution and frequency of excision have not been determined for the peanut genome. In order to characterize AhMITE1s, their genomic diversity and transposition ability was investigated. Southern blot analysis indicated high AhMITE1 copy number in the genomes of A. hypogaea, A. magna and A. monticola, but not in A. duranensis. A total of 504 AhMITE1s were identified from the MITE-enriched genomic libraries of A. hypogaea. The representative AhMITE1s exhibited a mean length of 205.5 bp and a GC content of 30.1%, with AT-rich, 9 bp target site duplications and 25 bp terminal inverted repeats. PCR analyses were performed using primer pairs designed against both flanking sequences of each AhMITE1. These analyses detected polymorphisms at 169 out of 411 insertional loci in the four peanut lines. In subsequent analyses of 60 gamma-irradiated mutant lines, four AhMITE1 excisions showed footprint mutations at the 109 loci tested. This study characterizes AhMITE1s in peanut and discusses their use as DNA markers and mutagens for the genetics, genomics and breeding of peanut and its relatives

底部黒色付着物の材質分析と放射性炭素年代測定

Infrared spectroscopic analysis and radiocarbon dating by accelerator mass spectrometry (AMS) were conducted on black material filled in the bottom of hasō, collected at the Shindate site, Higashihiroshima. The black material is shiny black, accompanied by sand, gravel, and plant remains, and was viscous when the sample was taken. Infrared spectroscopic analysis showed apparent absorption of hydrocarbons and the absorption of urushiol, which characterizes raw lacquer. The black material is identified as lacquer. The age ranges obtained by calibration of the 14C ages were 606-626 cal AD (45.46%) and 636-646 cal AD (22.81%) in the 1σ calendar year range and 600-651 cal AD (95.45%) in the 2σ calendar year range. The carbon dating results are consistent with hasō, which contains lacquer

Development of Training Games of Physical Posture for People with Developmental Disorders

Abstract—This paper describes two prototypes of training games of physical posture adaptive for people with developmental disorders. Two types of games are developed and their prototypes are produced. One is a game for exercise user’s body posture control. The other is a simulator of holding some object horizontally. Though it is said that ASD people generally have resistance against new, inexperienced items, all of the ASD subjects are interested in the games without refusal. This fact is considered to be an effective utilization of attraction and diffusing potential that games have.

Improvement of Training Games of Physical Posture for People with Developmental Disorders

Abstract—This paper describes improvements for training game of physical posture adaptive for people with developmental disorders, which is developed and already reported by the authors. The Game is a game for exercise user’s body posture control. Though it is said that ASD people generally have resistance against new, inexperienced items, all of the ASD subjects are interested in the games without refusal. This fact is considered to be an effective utilization of attraction and diffusing potential that games have. Through this improvement, the Game has been improved to the level that it can be used in the classes of schools by teachers
