Previous research has described a woman of reproductive age who presented with a vesicouterine fistula (VUF) of 20 months' duration. The VUF was lined with a metaplastic glandular epithelium containing both estrogen receptors (ER) and progesterone receptors (PR) in abundance. The aim of the present investigation was to evaluate the histology of the VUF canal when exposure to urine of the cellular elements within the fistula was of much shorter duration. A 41-year-old woman who developed a VUF during her third cesarean section was treated with transvesical fistula excision, electrocoagulation, and subsequent attempted hormonal treatment...

Three-dimensional (3D) in vitro microphysiological cultures, such as spheroids and organoids, promise increased patient relevance and therapeutic predictivity compared with reductionist cell monolayers. However, high-throughput characterization techniques for 3D models are currently limited to simplistic live/dead assays. By sectioning and staining in vitro microtissues, researchers can examine their structure; detect DNA, RNA, and protein targets; and visualize them at the level of single cells. The morphological examination and immunochemistry staining for in vitro cultures has historically been done in a laborious manner involving testing one set of cultures at a time...

BACKGROUND: Breast cancer is the most common malignancy affecting the Iraqi population and the leading cause of cancer related mortality among Iraqi women. It has been well documented that prognosis of patients depends largely upon the hormone receptor contents and HER-2 over expression of their neoplasm. Recent studies suggest that Triple Positive (TP) tumors, bearing the three markers, tend to exhibit a relatively favorable clinical behavior in which overtreatment is not recommended...

BACKGROUND: Breast carcinomas (BC) belong to a heterogeneous group of malignant diseases. Correct categorization of BC based on molecular biomarkers has a very important role in deciding the proper course of therapy for each patient. It has been already shown that the decrease of TIMP metalloproteinase inhibitor 3 (TIMP-3) together with overexpression of microRNA-21 (miR-21) might be involved in the process of BC invasion. This is the first study that examined relationship among miR-21, TIMP-3 mRNA and TIPM-3 protein levels in BC groups formed according to invasiveness...

Triple negative breast cancer (TNBC) is a particularly important breast cancer subtype with an aggressive clinical phenotype that is associated with a higher likelihood of metastasis. This subtype is characterized by an absence of the estrogen (ER) and progesterone (PR) receptors, as well as the human epidermal growth factor receptor 2 (HER2/HER neu). The absence of the three receptors significantly reduces targeted treatment options for patients with TNBC and as such, there is an urgent need to identify novel treatment targets...

d-Glucuronyl C5-epimerase (GLCE) is one of key enzymes in heparan sulfate biosynthesis and possesses tumour-suppressor function in breast carcinogenesis. Here, we investigated a potential involvement of GLCE polymorphism(s) in breast cancer development in Siberian women population. Comprehensive analysis of SNP databases revealed GLCE rs3865014 (Val597Ile) missense polymorphism as the main significantly present in human populations. According the TaqMan-based SNP assay, allele distributions for the rs3865014 (A>G) were similar in healthy Siberian women (n=136) and cancer patients (n=129) (A0,73:G0,27) and intermediate between the European and Asian populations, while genotype distributions were different, with the increase of AG rate in breast cancer patients (OR=1...
