Background: The breast imaging-reporting and data system (BI-RADS) grading has a great advantage in diagnosing breast diseases, but with some limitations.
Aims: The study analyzed the value of ultrasound-guided core needle biopsy (CNB) in diagnosing BI-RADS grades 3, 4, and 5 breast cancer.
Methods: Breast cancer patients at BI-RADS grades 3 to 5 received breast ultrasonography, ultrasound-guided CNB and immunohistochemical examination. Receiver operating characteristic (ROC) curve was made to test diagnostic efficiency of regression model.
Results: Calcification was positively correlated with expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor (HER)-2. The areas of 4 ROC curves were 0.752, 0.805, 0.758, and 0.847, and the 95%CI was 0.660 to 0.844, 0.723 to 0.887, 0.667 to 0.849, and 0.776 to 0.918, respectively. BI-RADS grades 3 to 5 were positively correlated with expression of ER, PR and human epidermal growth factor receptor-2 (HER-2). Statistical significance existed between grade 5 and expression of ER, PR and HER-2, and between grade 4 and expression of HER-2.
Conclusions: The study demonstrates that BI-RADS can be used as an effective evaluation method in the diagnosis of breast diseases before invasive operation, and it has higher diagnostic accuracy if combined with pathological examinations.

Contaminant-Associated Disruption of the Skin Transcriptome in the Endangered St. Lawrence Estuary Beluga.

The St. Lawrence Estuary (SLE) beluga () population in Canada is Endangered, and endocrine disrupting contaminants, such as polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and other halogenated flame retardants, have been identified as a threat to the recovery of this population. Here, potential impacts of these contaminants on SLE beluga were evaluated by comparing skin transcriptome profiles and biological pathways between this population and a population less exposed to contaminants (Eastern Beaufort Sea) used as a reference.

Objective: Aim: To evaluate the expression levels of SOX-10 in tissues of bladder tumor and to prove the correlation between SOX-10 expression and clinicopathological characteristics of bladder tumors, including patient age, sex, tumor grade, and muscle invasion.
Patients And Methods: Materials and Methods: Forty formalin fixed paraffin embedded FFPE tissue blocks gathered by transurethral resection of bladder tumor are collected from teaching hospitals at Al-Najaf governorate. Those blocks were stained by hematoxylin and eosin.

Hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN) is a neurodegenerative disease caused by mutations in the gene encoding transthyretin (TTR). Despite amyloid deposition being pathognomonic for diagnosis, this pathology in nervous tissues cannot fully account for nerve degeneration, implying additional pathophysiology for neurodegeneration, which, however, has not yet been fully elucidated. In this study, neuroinflammation in ATTRv-PN was investigated by examining nerve morphometry, the blood-nerve barrier, and macrophage infiltration in the sural nerves of ATTRv-PN patients and the sciatic nerves of a complementary mouse system, i.

Background: Deficiency of adiponectin and its downstream signaling may contribute to the pathogenesis of kidney injury in type 2 diabetes. Adiponectin activates intracellular signaling via adiponectin receptors 1 and 2 (AdipoR1 and AdipoR2), but the role of AdipoR-mediated signaling in glomerular injury in type 2 diabetes remains unknown.
Methods: The expression of AdipoR1 in the kidneys of people with type 2 diabetes and the expression of podocyte proteins or injury markers in the kidneys of AdipoR1-knockout (AdipoR1-KO) mice and immortalized AdipoR1-deficient human podocytes were investigated by immunohistochemistry and immunoblotting.
