question:
Context: Apicomplexan parasites actively release transmembrane (TM) adhesive proteins involved in host cell attachment and invasion. Rhomboids, a family of intramembrane serine proteases, cleave these secreted adhesive proteins within their TM domains as an essential step in completing the invasion process. In Cryptosporidium parvum, the activity of rhomboids in cleaving microneme proteins (MICs) has not been reported. In the present study, the interaction between C. parvum rhomboids (CpROM1 and CpROM4) and C. parvum microneme proteins (CpGP900 and CpTRAP-C1) was investigated using yeast two-hybrid assay and co-immunoprecipitation assays.', 'Our study demonstrated that CpROM1 protein could interact with CpGP900 protein in co-transformed AH109 yeasts. Analysis of these proteins in co-transfected mammalian cells showed that the cleavage product of the CpGP900 protein was detected in the co-transfected cells. As control, CpGP900 only was transfected into cells and no cleavage was observed. The results suggested that CpGP900 protein was the substrate of CpROM1. Moreover, CpROM1 and CpROM4 could not cleave CpTRAP-C1 protein, which is the substrate of T. gondii rhomboid 2.
Answer: Our results showed that CpROM1 is an active protease that is involved in microneme protein CpGP900 cleavage, which lay the foundation for further research on the mechanisms of C. parvum invasion.
answer:
Does cryptosporidium parvum rhomboid1 have an activity in microneme protein CpGP900 cleavage?


question:
Context: Anorectal manometry provides objective information about anorectal function, but its results depend on the examiner's skill, the type of equipment, and subject characteristics like age or gender. This single institution, prospective study was performed to investigate the effect of gender and age on the results of anorectal manometry.", 'All included subjects completed a questionnaire to assess their bowel function. The survey included 13 validated questions (eight on constipation and five on incontinence) and was used to exclude subjects with pathological constipation or incontinence. Subjects with normal bowel function underwent anorectal manometry to measure anal sphincter length (ASL), maximum resting pressure (MRP), and maximum squeeze pressure (MSP), and the results were compared by gender and age.', 'The mean age of the 154 participants (94 male and 60 female) was 59.1 years. ASL was greater in men (4.23 vs. 3.85 cm, p\u2009<\u20090.001). MRP was not significantly different according to gender (p\u2009=\u20090.93), but MSP was higher in men (190.18 vs. 116.49 mmHg, p\u2009<\u20090.001). ASL did not correlate with age (p\u2009=\u20090.707). MRP was inversely related to age in both men (R (2)\u2009=\u20090.152, p\u2009<\u20090.001) and women (R (2)\u2009=\u20090.282, p\u2009<\u20090.001), and MSP only in women (R (2)\u2009=\u20090.210, p\u2009<\u20090.001).
Answer: Anorectal manometric parameters are influenced by gender and age. This should be taken into consideration when interpreting manometric readings in a clinical setting.
answer:
Are anorectal manometric parameters influenced by gender and age in subjects with normal bowel function?


question:
Context: Studies examining physical activity levels have used samples primarily composed of non-Latino Whites and have focused on leisure time physical activity (LTPA). Additionally, few studies have investigated differences in physical activity between Latino men and Latina women, or the relationship between acculturation and activity.', 'To examine the subjective and objective physical activity of Latinos and gender differences in physical activity and the extent to which LTPA and non-LTPA were predictive of overall accelerometer physical activity. An additional objective was to examine the relationship between acculturation and different types of physical activity.', 'Data were obtained from 155 Latinos (n = 86 female, n = 69 male). Comparisons were made between Latino men and women.', 'Latino men participated in significantly greater occupational and overall objective and subjective physical activity than Latina women; however, women participated in greater household activity. Regression analyses demonstrated that recreational, occupational, and household activity were significant predictors of overall accelerometer physical activity for the complete sample. Among women, recreational and household activity were significant predictors; however, overall accelerometer physical activity was not significantly predicted in men. Additionally, it was demonstrated that acculturation was related to occupational activity, but not to recreational activity.
Answer: These results suggest that gender differences in physical activity are present among Latinos and that acculturation may be a correlate of various types of physical activity.
answer:

Does gender and acculturation influence on physical activity in Latino adults?
