Purpose: The experiences of a teenage girl with Rett syndrome who was being educated in an inclusive middle school are described to provide a better understanding of how social relationships create meaningful contexts for individuals with limited skills. The case example is used to illustrate the principle that contexts (including expectancies, acceptance, philosophical principles) can be designed to support meaningful social relationships, despite social and intellectual disabilities. Method: Naturalistic observations of social interactions over a two year period are reported to illustrate the possible types of social relationship between this young person and her adolescent friends and peers. Results/Conclusions: While someone with this syndrome might be judged objectively to have minimal social skills, an accepting social environment willing to read minimal communicative cues provided the context for many typical social interactions. Since contexts require subjective judgement, the post-modern concept that disability represents a social construction can be viewed as a metaphor compatible with the reality that careful planning and structuring of the environment is in some instances the most appropriate intervention focus rather than the person with a disability. The sorts of positive friendship experiences described in this paper did not occur spontaneously, or by chance alone, nor were they the result of social skills instruction. Instead, they were associated with observable social behaviour by caregivers and peers who were extending their own repertoires to accommodate someone objectively determined to have a severe disability. 相似文献

The present study evaluated the toxicity of Microgramma vacciniifolia rhizome lectin (MvRL) to Artemia salina, human tumour cell lines (larynx epidermoid carcinoma Hep-2, NCI-H292 lung mucoepidermoid carcinoma, and chronic myelocytic leukaemia K562), and normal peripheral blood mononuclear cells (PBMCs), as well as to Biomphalaria glabrata embryos and adults. MvRL was toxic to A. salina (LC50 = 159.9 μg/mL), and exerted cytotoxic effects on NCI-H292 cells (IC50 = 25.23 μg/mL). The lectin (1–100 μg/mL) did not affect the viability of K562 and Hep-2 tumour cells, as well as of PBMCs. MvRL concentration of 1, 10, and 100 μg/mL promoted malformations (mainly exogastrulation) in 7.8%, 22.5%, and 27.7% of embryos, respectively, as well as delayed embryo development in 42.0%, 69.5%, and 54.7% of embryos, respectively. MvRL at a concentration of 100 μg/mL killed B. glabrata embryos (17.7%) and adults (25%). Further, MvRL damaged B. glabrata reproductive processes, which was evidenced by observations that snails exposed to the lectin (100 μg/mL) deposited fewer eggs than those in the control group, and approximately 40% of the deposited eggs exhibited malformations. Comparison of these results with that from A. salina assay indicates that MvRL is adulticidal at the concentration range which is toxic to environment. In conclusion, the cytotoxicity of MvRL on tumour cell and absence of toxicity to normal cell indicate its potential as chemotherapeutic drug. Also, the study revealed that the lectin is able to promote deleterious effects on B. glabrata embryos at environmentally safe concentrations. 相似文献

Immune gamma globulin (IgG) has a long history in the treatment of both primary immune deficiency and autoimmune disorders. Disease indications continue to expand and new-generation products increase the versatility of delivery. This review encompasses a historical perspective as well as current and future implications of human immune globulin for the treatment of immune-mediated illness. 相似文献

In a study of 144 women, mainly self-designated PMS sufferers, the premenstrual depression experienced was, apart from its shorter duration, quantitatively and qualitatively similar to major depressive disorder for a substantial proportion of subjects. The associations with previous history of depression were complex: the severity of premenstrual depression was related to previous history of postnatal depression, whereas its duration (i.e., whether it persisted through longer) was related to a history of treatment with antidepressants. Two independent dimensions are proposed. (i) A menstrual cycle-related factor which in vulnerable women can results in severe and disabling premenstrual dysphoria, and which may be aetiologically related to a subgroup of postnatal depression. (ii) In a minority of women a more general propensity for depressive illness evidence as a tendency for any premenstrual depression to be prolonged. 相似文献

Sexual selection via male mate choice has often been implicated in the evolution of permanently enlarged breasts in women.
While questionnaire studies have shown that men find female breasts visually attractive, there is very little information
about how they make such visual judgments. In this study, we used eye-tracking technology to test two hypotheses: (1) that
larger breasts should receive the greatest number of visual fixations and longest dwell times, as well as being rated as most
attractive; (2) that lightly pigmented areolae, indicative of youth and nubility, should receive most visual attention and
be rated as most attractive. Results showed that men rated images with medium-sized or large breasts as significantly more
attractive than small breasts. Images with dark and medium areolar pigmentation were rated as more attractive than images
with light areolae. However, variations in breast size had no significant effect on eye-tracking measures (initial visual
fixations, number of fixations, and dwell times). The majority of initial fixations during eye-tracking tests were on the
areolae. However, areolar pigmentation did not affect measures of visual attention. While these results demonstrate that cues
indicative of female sexual maturity (large breasts and dark areolae) are more attractive to men, patterns of eye movements
did not differ based on breast size or areolar pigmentation. We conclude that areolar pigmentation, as well as breast size,
plays a significant role in men’s judgments of female attractiveness. However, fine-grained measures of men’s visual attention
to these morphological traits do not correlate, in a simplistic way, with their attractiveness judgments. 相似文献
