Differential Expression of Hox and Notch Genes in Larval and Adult Stages of Echinococcus granulosus

This investigation aimed to evaluate the differential expression of HoxB7 and notch genes in different developmental stages of Echinococcus granulosus sensu stricto. The expression of HoxB7 gene was observed at all developmental stages. Nevertheless, significant fold differences in the expression level was documented in the juvenile worm with 3 or more proglottids, the germinal layer from infected sheep, and the adult worm from an experimentally infected dog. The notch gene was expressed at all developmental stages of E. granulosus; however, the fold difference was significantly increased at the microcysts in monophasic culture medium and the germinal layer of infected sheep in comparison with other stages. The findings demonstrated that the 2 aforementioned genes evaluated in the present study were differentially expressed at different developmental stages of the parasite and may contribute to some important biological processes of E. granulosus.

Magnetic Resonance Imaging Features of Adenosis in the Breast / 한국유방암학회지

PURPOSE: Adenosis lesions of the breast, including sclerosing adenosis and adenosis tumors, are a group of benign proliferative disorders that may mimic the features of malignancy on imaging. In this study, we aim to describe the features of breast adenosis lesions with suspicious or borderline findings on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). METHODS: In our database, we identified 49 pathologically proven breast adenosis lesions for which the final assessment of the breast MRI report was classified as either category 4 (n=45) or category 5 (n=4), according to the Breast Imaging Reporting and Data System (BI-RADS) published by the American College of Radiology (ACR). The lesions had a final diagnosis of either pure adenosis (n=33, 67.3%) or mixed adenosis associated with other benign pathologies (n=16, 32.7%). RESULTS: Of the 49 adenosis lesions detected on DCE-MRI, 32 (65.3%) appeared as enhancing masses, 16 (32.7%) as nonmass enhancements, and one (2.1%) as a tiny enhancing focus. Analysis of the enhancing masses based on the ACR BI-RADS lexicon revealed that among the mass descriptors, the most common features were irregular shape in 12 (37.5%), noncircumscribed margin in 20 (62.5%), heterogeneous internal pattern in 16 (50.0%), rapid initial enhancement in 32 (100.0%), and wash-out delayed en-hancement pattern in 21 (65.6%). Of the 16 nonmass enhancing lesions, the most common descriptors included focal distribution in seven (43.8%), segmental distribution in six (37.5%), clumped internal pattern in nine (56.3%), rapid initial enhancement in 16 (100.0%), and wash-out delayed enhancement pattern in eight (50.0%). CONCLUSION: Adenosis lesions of the breast may appear suspicious on breast MRI. Awareness of these suspi-cious-appearing features would be helpful in obviating unnecessary breast biopsies.

Impact of maternal ramadan fasting on growth parameters in exclusively breast-fed infants

There are many advantages of breast milk for infants. The impact of Ramadan fasting of breast-feeding mothers on their exclusively breast-fed infants' growth is still not clear. The objective of this study is to determine the impact of maternal Ramadan fasting on growth parameters of exclusively breast-fed infants. This cohort study was conducted during Ramadan and five months after Ramadan on 116 healthy, exclusively breast-fed infants aged 15 days to 6 months. 36 infants, whose mothers fasted throughout Ramadan [case group] and 80 infants, whose mothers did not fast [control group], were enrolled in the study. All infants underwent periodic physical examinations, twice in Ramadan, 3 times in the second month and twice monthly in the next 4 months. The data analyses were done using a repeated measure analysis of variance. Statistical significance was defined as P<0.05. Analyses were performed using SPSS statistical package and repeated measures ANOVA. All growth parameters increased during the study period [P< 0.05], rate of increase being the same for both groups [P>0.05]. There is obvious increasing trend for all growth parameters; this trend depends on age and is almost similar for both groups. Ramadan fasting by breast-feeding mothers did not adversely affect the growth parameters of exclusively breast-fed infants in short-term
