Lemur catta Troop D at Berenty Reserve has been studied intermittently for 35 years. During 90 hours of continuous sampling in August 1998, I observed and mapped troop movement and scent marking. I compared these observations with data from June, 1975. The core of Troop D1's 1998 home range is the same as for Troop D in 1975. Sixty-two percent of Troop D1's time in 1998 was spent in the 1975 home range, and 52% of their scent marks were placed in that 1975 home range. The remainder of their time was spent in an extension of their home range, which is now an area of confrontation with an adjacent troop. They used the same sleeping trees in the 2 years, and all of the 1998 scent marks deposited in the 1975 home range were placed in the same locations marked in 1975. The similarities in their use of space in 1975 and 1998 were remarkable.  相似文献

Abstract

We aimed to find new physiological effects of the Japanese diet. First, to determine the key components in serum from mice fed the 1975 diet, serum from mice fed the 1960, 1975, 1990 or 2005 Japanese diet was analyzed using CE-TOFMS and LC-TOFMS. Based on these results, the key components were determined by principal component analysis. Among the identified compounds, GABA was included. Therefore, a stress reduction effect was inferred as a novel physiological effect of this diet. Next, we tested whether the 1975 diet had an actual stress reduction effect in mice. Mice were given the 1975 diet or a control diet for 4 weeks, after which they were divided into restraint stress and non-stress groups. Mice fed the 1975 diet had significantly decreased stress parameters compared with those fed the control diet. These results provide the first evidence that the 1975 Japanese diet has a stress reduction effect.  相似文献

Abstract

The present research focuses on childed versus childless intentions and subsequent behavior and intentions for a panel of U. S. women. Utilizing data from the 1970 and 1975 National Fertility Surveys (reinterviewed women), we ascertain the consistency between intentions (1970) and behavior and intentions (1975). We find that while women who expressed a zero parity intention in 1970 were very consistent in their behavior and intentions in 1975, nearly 30 per cent of those women intending children had no children by 1975. Furthermore, of these 30 per cent, one‐third had changed their intention to zero parity by 1975. We find that changing intentions from more than zero to zero is associated with higher levels of education, slightly higher income, and to a lesser degree with the importance given religion and with labor force participation.  相似文献

There is increasing evidence that functional crosstalk between GPCRs and EGFR contributes to the progression of colon, lung, breast, ovarian, prostate and head and neck tumors. In this study, we performed multiple analyses of GPCR expression in a gefitinib-resistant non-small cell lung cancer (NSCLC) cell line, H1975, which harbors an L858R/T790M mutation. To determine the expression profile of mRNAs encoding 384 GPCRs in normal human lung fibroblast (NHLF) and H1975 cells, a GPCR-specific microarray analysis was performed. A heat-map of the microarray revealed considerable differences in the expression of GPCRs between NHLF and H1975 cells. From the GPCR expression list, we selected some GPCR agonists/antagonist to investigate whether the respective ligands could affect the growth of H1975 cells. Among them, treatment with either a selective antagonist of adenosine A2a receptors, which were highly expressed in H1975 cell and another gefitinib-resistant NSCLC cells, HCC827GR cells or “small interfering RNA” (siRNA) targeting adenosine A2a receptors produced a significant decrease in cell viability of both H1975 and HCC827GR cells. Among up-regulated GPCRs in H1975 cells, Gs-, Gi- and Gq-coupled GPCRs were expressed almost equally. Among down-regulated GPCRs, Gi-coupled GPCRs were dominantly expressed in H1975 cells. The present results suggest that multilayered crosstalk between GPCRs and EGFR may play an important role in orchestrating downstream signaling molecules that are implicated in the development of gefitinib-resistant NSCLC.  相似文献

目的:探讨人髓细胞白血病基因-1(myeloid cell leukemia-1,Mcl-1)是否参与调控非小细胞肺癌(non-small cell lung cancer,NSCLC)对EGFR-TKIs的敏感性,为非小细胞肺癌的治疗提供新的思路。方法:通过Western blot方法检测EGFR-TKIs敏感细胞H3255和耐药细胞H1975中Mcl-1蛋白的表达水平。分别给予敏感细胞H3255和耐药细胞H1975 EGFR-TKIs处理后检测细胞凋亡情况和Mcl-1蛋白表达水平。设计并合成特异性si RNA下调耐药细胞H1975中Mcl-1的表达,采用脂质体转染后通过流式细胞技术检测细胞的凋亡情况。结果:H3255细胞Mcl-1表达水平明显低于H1975细胞。一代EGFR-TKIs Gefitinib显著降低H3255细胞Mcl-1表达而不能减少H1975细胞Mcl-1表达。H1975细胞经二代EGFR-TKIs Afatinib和三代EGFR-TKIs AZD9291处理后Mcl-1表达明显减少。特异性si RNA下调H1975细胞Mcl-1表达可以促进细胞凋亡。结论:Mcl-1参与了调节NSCLC对EGFR-TKIs的敏感性,可能成为防止或逆转NSCLC对EGFR-TKIs耐药的潜在靶点。  相似文献

The water mass below 3.5 m in Spruce Knob Lake was artificially aerated with a modified full lift aerator during two consecutive summers (1974 and 1975) of an investigation that began in July of 1973 and ended in September, 1975. Artificial aeration increased water temperature below 3.5 m without causing destratification. Several chemical parameters were significantly affected by artificial aeration, especially from July to autumnal overturn in 1974 and 1975. Below 3.5 m, total inorganic carbon, total alkalinity, nitrite, soluble reactive phosphorus, and total phosphorus, were lower during aeration than in the summer of no aeration (1973). Although artificial aeration lowered soluble reactive and total phosphorus, there was no significant impact on the phosphorus budget of the impoundment. In 1975, continuous aeration from vernal overturn to autumnal overturn resulted in higher nitrate concentrations below 3.5 m than in the preceeding summers. Lower pH values encountered through the whole water column in 1975 followed a brief isothermal interruption of summer stratification in early June. There was no direct effect of artificial aeration on either temperature or water chemistry parameters in the epilimnion. Significantly lower chlorophyll concentrations observed in 1975 were related to destratification in June. Primary production was unaffected by aeration.  相似文献

This essay is about the 1975 JEEM paper by Fran?oise Dieterlen-Lièvre (Dieterlen-Lièvre, 1975) and the studies that followed it, which indicated that the adult hematopoietic system in the avian embryo originates, not from the blood islands of the extraembryonic yolk sac as was then believed, but from the body of the embryo itself. Dieterlen-Lièvre's 1975 paper created a paradigm shift in hematopoietic research, and provided a new and lasting focus on hematopoietic activity within the embryo body.  相似文献

This investigation was performed during a 5-yr period (1974–1978) in the oligotrophic Lake Langvatn, Central Norway. In 1975 and 1976 the lake was enriched with a commercial fertilizer, In 1975 increase in phytoplankton biomass was first recorded more than three weeks after the fertilization started, despite a near fivefold increase in the primary production after fertilizer application. The mean seasonal biomass increased from c. 3500 mg wet weight m−2 in 1974 to 4400 mg in 1975. In 1976 the biomass increased to near 9600 mg −2 and the seasonal primary production to 49.0 g C m−2 (22.2 g C in 1975), despite a reduction in the nutrients added. Chrysophytes constituted the largest share of the seasonal algal biomass in all years, but in fertilization periods cryptophytes dominated in 1975 and diatoms, chlorophytes and cryptophytes in 1976. The highest biomass turnover rate was recorded during a period of cryptophyte dominance. The different biomass and production development in the fertilization years may be explained by a change in the consumer level.  相似文献

Peripheral plasma progesterone and corticosteroid concentrations were studied in ewes grazing oestrogenic pastures during oestrus, pregnancy and parturition in 1974 and during pregnancy in 1975. Haemoglobin (Hb) type A ewes had significantly higher mean corticosteroid concentrations than HbB ewes in both years. In 1974 the concentration of progesterone did not differ significantly between Hb types whilst in 1975 the concentration was significantly (P less than 0.001) higher in HbA ewes. The mean corticosteroid concentrations were higher in selenium-supplemented ewes of both Hb types than in unsupplemented ewes in 1974 but lower in 1975. Selenium treatment did not significantly influence the progesterone concentration in ewes of both Hb types in 1974 but significantly (P less than 0.01) increased in 1975. It is concluded that the higher concentration of plasma corticosteroids or factors regulating the relationship between corticosteroids and progesterone could be responsible for the higher estimates of embryonic mortality reported in HbA ewes.  相似文献

In the framework of a study aimed to ascertain the possibilities of infection transmission from mother to child the athors examined serologically gravid women for toxoplasmosis and antibodies against listeriosis, using routine methods, in Austria in 1974, 1975 and 1975. Almost all gynecologists of the region of Styria (Austrial), who systematically delivered data concerning abortions, premature births and stillbirths, were invited to take part in the study. At the same time data concerning domestic and wild animals examined for antibodies against listeriosis in Austria in 1974, 1975, 1976 and 1977, were compared.  相似文献
