RESUMEN

Innate lymphoid cells (ILCs) are key players during an immune response at the mucosal surfaces, such as lung, skin, and gastrointestinal tract. Giardia lamblia is an extracellular protozoan pathogen that inhabits the human small intestine. In this study, ILCs prepared from the lamina propria of mouse small intestine were incubated with G. lamblia trophozoites. Transcriptional changes in G. lamblia-exposed ILCs resulted in identification of activation of several immune pathways. Secretion of interleukin (IL)-17A, IL-17F, IL-1β, and interferon-γ was increased, whereas levels of IL-13, IL-5, and IL-22, was maintained or reduced upon exposure to G. lamblia. Goup 3 ILC (ILC3) was found to be dominant amongst the ILCs, and increased significantly upon co-cultivation with G. lamblia trophozoites. Oral inoculation of G. lamblia trophozoites into mice resulted in their presence in the small intestine, of which, the highest number of parasites was detected at the 5 days-post infection. Increased ILC3 was observed amongst the ILC population at the 5 days-post infection. These findings indicate that ILC3 from the lamina propria secretes IL-17 in response to G. lamblia, leading to the intestinal pathology observed in giardiasis.

RESUMEN

PURPOSE: The purpose of this research is to enhance organizational competitiveness of health centers as well as private medical institutions serving as public health and medical institutions. It tries to help them to cope with the requirements from health consumers, to enhance public health nurses' job performance. METHODS: After verifying the reliability of the tool, confirmatory factor analysis was used to detect a model, in which valid path coefficients exist among variables. The detected model was then selected as the subject and its validity was verified. Finally, a structural equation model was applied to verify whether the estimate was suitable for the purpose of this research. RESULTS: As for the nursing organizational culture, the public health nurses considered relation-oriented culture the most desirable. As for the self-leadership, they considered self-compensation the most desirable. It was found that mediating effects of self-leadership was partially significant. CONCLUSION: To enhance job performance, it is necessary to make a transition from the organizational culture to the relation-oriented culture and it is also necessary to develop a program capable of reinforcing self-leadership. In addition, it is necessary to conduct a research to verify whether such a developed self-leadership program is influential on job performance enhancement.

RESUMEN

The purpose of this study was to examine the effects of an abdominal obesity management program on a woman's body composition and physiological indicators. A sample of 20 women who were 33 to 62 years old with abdominal obesity (greater than 80cm of waist circumference) participated in the program for 12 weeks. The program consisted of aerobic dance and yoga for one hour, twice a week. Their body composition was measured with BMI, body fat %, waist circumference, and waist/hip ratio. The physiological indicators were measured by systolic blood pressure, blood glucose, total cholesterol, and triglycerides before and after the program. The results showed that waist circumference, waist/hip ratio, and fasting blood glucose decreased significantly after the program. However, BMI, systolic blood pressure, and blood lipids did not change. An abdominal obesity management program with aerobic dance and yoga is partially effective in decreasing abdominal obesity. Further studies are required to replicate the study with a control group using an experimental design.
