The correspondence between interview-assessed parental emotional attitudes toward a particular offspring (expressed emotion [EE]) and the psychophysiological reactivity of both parents and their children during a series of direct family interactions was investigated for a sample of 52 disturbed but nonpsychotic adolescents (aged 14–29 yrs). Parents who expressed an excessive number of critical comments during the interview were designated as high EE, and the remainder were designated as low EE. Both high-EE parents and their adolescent offspring became significantly more psychophysiologically reactive as the 1st of 2 family confrontations in which they participated progressed. Adolescents also showed greater arousal when anticipating interactions with a high-EE parent when that parent was first in the experimental sequence. These results are combined with those of a previous study by the authors and J. A. Doane (see record 1984-06985-001) to support the notion that the EE measure is marking clearly defined family emotional climates that appear to be related to the subsequent onset of schizophrenia spectrum disorders in this adolescent sample.

We examined whether heart rate (HR) could be used to estimate energy expenditure (EE) in cattle. Six Hereford heifers (345 +/- 10.8 kg BW) 12 mo of age were implanted with HR radio transmitters and maintained in individual pens under the following treatments: 1) shade or sun exposure, 2) high- or low-energy diet, and 3) feeding in morning or afternoon. The HR of animals was measured every .5 h during 3 mo; measurements of oxygen consumption and HR were made simultaneously in the morning and in the afternoon while animals were resting and exercising. Average daily HR (52 +/- 4 beats/min) and average daily EE (380 +/- 9 kJ/kg(.75)) in animals on the low-energy diet were less than values in animals on the high-energy diet (94 +/- 4 beats/min and 653 +/- 9 kJ/ kg(.75), respectively). For each animal and within each diet, linear regressions best described the relationship between HR and EE in resting animals, whereas quadratic regressions best described this relationship for exercising animals. The quadratic equation for the exercising animals could also be used for resting animals. In addition, a constant value of EE per heart beat (EE pulse) for each individual resting animal was found and gave accurate estimations. This method was convenient because 1) no exercise equipment was needed to generate the regression equations and 2) EE pulse was less affected by diet than was EE estimated by regression equations. We conclude that HR, a relatively easy measurement, can be useful and accurate in estimating EE. To increase the accuracy of the estimation of EE by HR, the relationship of HR to EE should be established for each animal. In addition, the nutritional regimen for the animal in which EE is estimated should be used for the animal in establishing the relationship.  相似文献

The strong hepatic estrogenic actions of ethinylestradiol (EE) are very likely to be the cause of the cardiovascular morbidity related to the use of combined oral contraceptives (COCs). This survey presents results of EE replacement in COCs with natural 17beta-estradiol (E2) in the following stages: reduction of EE to daily doses of 0.01 mg and concomitant replacement with E2 (as valerate, EV), complete replacement of EE with E2 using a novel multiphasic combination containing EV and the progestin dienogest (DNG), and the use of natural E2 to develop estrogen sulfamates (J 995) showing sufficient dissociation of uterine from liver estrogenicity. Recent data from preclinical and clinical studies show that these approaches seem to be promising.  相似文献

In May 1993, we collected unfed ticks in Anan, Tokushima Prefecture, Shikoku District, Japan, a highly endemic area of Japanese spotted fever (JSF). We isolated JSF rickettsiae from these ticks by inoculating tick-emulsions into L-929 cells. Of the four genera and seven species of ticks examined, only one larva of Dermacentor taiwanensis Sugimoto yielded a rickettsial isolate. The isolate (DT-1 strain) was found to belong to the serotype common to the causative agent of JSF. This was based on its specific reactivity to mouse antisera and to a monoclonal antibody to JSF rickettsiae from the Shikoku District. This is the first tick-borne spotted fever group of rickettsia isolated in Japan. However, all stages of D. taiwanensis infrequently parasitize humans. Some ticks in the genus Haemaphysalis commonly infest humans and are frequently found to be rickettsia-positive in the hemolymph test when using the monoclonal antibody mentioned above. Therefore, the vectors of JSF rickettsiae to humans may be a complex of tick species.  相似文献

为提高钛金属的硬度,增加其耐磨性能,将金属钛埋在B4C含量分别为5%和10%的B4C+KBF4+SiC硼化剂中,加热到950℃进行固体硼化,研究不同组成比例的硼化剂对硼化层的影响;在B4C含量为10%的条件下,分别加热到950℃和1 000℃进行固体硼化,研究不同温度对硼化层的影响。XRD测定的硼化层表面物相结构结果表明,钛金属表面的硼化层主要由TiB组成,晶体在200晶面择优取向。固体硼化结果的热力学分析认为,在硼势不足的固体硼化条件下,活性硼原子先和金属钛原子生成TiB,而不是生成TiB2。  相似文献

PURPOSE: The purpose of this study was to compare two commercially available accelerometers with indirect calorimetry in a group of older adults (x +/- SD; 70.6+/-3.7 yr; N = 86, 44 males and 42 females). METHODS: The accelerometers (Caltrac and Tritrac, Hemokinetics, Madison, WI) were worn while performing three submaximal, discontinuous (5 min exercise, 2 min recovery), progressive levels of treadmill walking and bench stepping. The treadmill exercise averaged 3.4 mph, at 0.4% grade, 3.0% grade, and 5.1% grade, while the stepping work rates (24 steps x min(-1)) were performed on 15.2-, 20.3-, and 25.4-cm steps. Estimated energy expenditure (EE) from the two accelerometers was compared with EE as measured by indirect calorimetry. RESULTS: The Caltrac significantly (P < 0.05) overestimated EE at the three treadmill work rates (10-52% difference) and underestimated EE at the three stepping work rates (-19% to -28% difference). When comparing the changes in EE between work rates one, two and three, the Caltrac was not sensitive to the changes (increase in EE) that occurred during graded treadmill walking but did detect some changes in the stepping exercise. The Tritrac significantly (P < 0.05) underestimated EE for the three work rates of both the treadmill and stepping exercise when compared with indirect calorimetry but did detect differences in EE among work rates during stepping exercise (P < 0.05). CONCLUSIONS: These data indicate that the magnitude of the differences between measured and estimated EE is affected by exercise mode and intensity and that caution is warranted when using the accelerometers in an attempt to quantify EE in older adults.  相似文献
