The Evaluation of Contralateral Breast Lesions in Breast Cancer Patients Using Reduction Mammoplasty

Purpose: This study evaluated the importance of routine pathological examination of contralateral breast specimens in breast cancer patients using reduction mammoplasty. Methods: The weight of breast tissue resected from the contralateral breast in 71 patients and the number of slices used for pathological evaluation were recorded. Breast lesions found in the contralateral breast and accompanying lesions with tumors were examined. Results: High risk proliferative lesions were reported in the contralateral breast of eight (11.2%) patients, and low-risk lesions were detected in 18 (25%). While the mean age of the patients with high-risk lesions was 45.6, it was 52.8 for the other patients (p = 0.036). Conclusion: Bilateral reduction mammoplasty may be beneficial to delineate some pathologies in contralateral breasts even in those patients with normal clinical and radiological findings. The incidental discovery of these pathologies is much more likely in young breast cancer patients

MicroRNA nomenclature and the need for a revised naming prescription

A central environment and interface for microRNA (miRNA) registry and repository and a general standardized framework for their systematic annotation was established over a decade ago. However, the numbers of experimentally and computationally identified miRNAs are swiftly accumulating, and new aspects of miRNA-mediated gene regulation are being revealed. Currently, it is of great significance that the annotation framework should be redefined to include newly discovered miRNA species such as the variants of mature miRNAs (isomiRNAs), and organellar miRNAs: cipomiRNAs and mitomiRNAs. It is also of great importance that key terminology referring to the novelty, evolutionary history or biogenesis of miRNAs, as well as the confidence of their identification are standardized in the literature and disseminated in a central miRNA registry. Here, we review the status of miRNA nomenclature, curation and critical points of need for a revision of miRNA nomenclature and terminology

Stress responsive miRNAs and isomiRs in cereals

Abiotic and biotic stress conditions are vital determinants in the production of cereals, the major caloric source in human nutrition. Small RNAs, miRNAs and isomiRs are central to post-transcriptional regulation of gene expression in a variety of cellular processes including development and stress responses. Several miRNAs have been identified using new technologies and have roles in stress responses in plants, including cereals. The overall knowledge about the cereal miRNA repertoire, as well as an understanding of complex miRNA mediated mechanisms of target regulation in response to stress conditions, is far from complete. Ongoing efforts that add to our understanding of complex miRNA machinery have implications in plant response to stress conditions. Additionally, sequence variants of miRNAs (isomiRNAs or isomiRs), regulation of their expression through dissection of upstream regulatory elements, the role of Processing-bodies (P-bodies) in miRNA exerted gene regulation and yet unveiled organellar plant miRNAs are newly emerging topics, which will contribute to the elucidation of the miRNA machinery and its role in cereal tolerance against abiotic and biotic stresses

Molluscum contagiosum with dermoscopic features in an unusual areola and nipple location

Molluscum contagiosum is a common, contagious viral skin disease that often affects children and adolescents. Involvement of the areola and nipple are rarely reported. Herein we report two young women with molluscum contagiosum on the areola-nipple complex and we discuss the dermoscopic features of the lesions at this unusual site
