Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare but serious complication in patients with breast implants, Patients are at risk of BIA-ALCL whether they receive breast implants for cosmetic reasons or for reconstructive purposes after surgery for breast cancer or prophylactic mastectomy. During the past decade, an increased number of reports have addressed BIA-ALCL. Herein, we describe BIA-ALCL in a transgender woman. The patient received breast implants as part of her gender transition and was diagnosed with BIA-ALCL 20 years later...

Hypoxia-induced chemoresistance (HICR) is a well-recognized phenomenon, and in many experimental models, hypoxia inducible factor-1α (HIF-1α) is believed to be a key player. We aimed to better understand the mechanism underlying HICR in a triple negative breast cancer cell line, MDA-MB-231, with a focus on the role of HIF-1α. In this context, the effect of hypoxia on the sensitivity of MDA-MB-231 cells to cisplatin and their stem-like features was evaluated and the role of HIF-1α in both phenomena was assessed...

Human epidermal growth factor receptor 2 (HER2) is an important biomarker for detection and treatment of different types of cancers such as breast, ovarian, stomach cancer. In this study, we developed a monoclonal antibody against the extracellular domain (ECD) of HER2 biomarker of breast cancer. For this purpose, the ECD-HER2 gene was amplified and cloned into an expression vector. Gene was generated in Escherichia coli BL21 (DE3) strain for expression of recombinant protein. The expressed protein was separated by SDS-PAGE and detected by anti-his monoclonal antibody in immunoblotting...

Besides the crucial role of hyperinsulinemia in the development of breast cancer with Type 2 diabetes mellitus (T2DM), it has been shown that hyperglycemia could contribute to promote cancer progression. A remarkable association within hyperglycemia, PKCδ and Ubiquitin-proteasome system (UPS) has been reported, suggesting that PKCδ may mediate high glucose-induced UPS activation in breast cancer cells. Although the independent effects of PKCδ or UPS on breast cancer and T2DM are increasingly supported by experimental evidence, the complex interactional link between PKCδ and UPS is still unclear...

Although it has been show that early detection through mammograms is the most effective way to reduce breast cancer mortality, breast cancer is the leading cause of cancer deaths among women worldwide with survival rates being even lower in low- and middle-income countries as compared to high-income countries. Despite the availability of breast cancer screening programs in Brazil through the public health system, some women do not participate in these programs due to structural and/or inter/intrapersonal barriers...

Breast Cancer Awareness Month (BCAM) increases screening attendance in the USA. However, this effect has not been investigated in Europe, where organized screening is widespread. We examined monthly attendance within the Norwegian Breast Cancer Screening Programme, 2005-15. Relative to October, the odds of attending screening in January, February, March, August, September or December were slightly decreased (ORadj 0.93-0.98, P ≤ 0.003 for all). BCAM may marginally increase attendance in October but seasonal factors such as weather may also explain this observed variation...

Evidence suggests contemporary population distributions of breast cancer estrogen receptor (ER) status may be shaped by earlier major societal events, such as the 1965 abolition of Jim Crow (legal racial discrimination in the US) and the Great Famine in China (1959-1961). We accordingly analyzed changes in ER status in relation to Jim Crow birth place among the 46,417 black and 339,830 white US-born non-Hispanic women in the 13 SEER Registry Group who were born between 1915 and 1979 and diagnosed (age 25-84, inclusive) between 1992-2012...

Integrative clustering is used to identify groups of samples by jointly analysing multiple datasets describing the same set of biological samples, such as gene expression, copy number, methylation etc. Most existing algorithms for integrative clustering assume that there is a shared consistent set of clusters across all datasets, and most of the data samples follow this structure. However in practice, the structure across heterogeneous datasets can be more varied, with clusters being joined in some datasets and separated in others...

Angiosarcomas are highly malignant and rare tumors of vascular or lymphatic endothelial cell origin with a poor prognosis. Lymphangiosarcoma associated with chronic lymphedema is known as Stewart-Treves syndrome. Stewart-Treves syndrome is primarily described in patients with lymphedema of an upper extremity occurring after breast cancer surgery including radical axillary lymph node dissection and subsequent radiotherapy. It is rarely described in the presence of idiopathic chronic lymphedema of the lower extremities...

Transfer learning in deep convolutional neural networks (DCNNs) is an important step in its application to medical imaging tasks. We propose a multi-task transfer learning DCNN with the aims of translating the 'knowledge' learned from non-medical images to medical diagnostic tasks through supervised training and increasing the generalization capabilities of DCNNs by simultaneously learning auxiliary tasks. We studied this approach in an important application: classification of malignant and benign breast masses...

The use of gold nanorods (AuNRs) that produce heat in response to near infrared (NIR) irradiation is an attractive approach to cancer photothermal therapy. AuNRs are usually prepared by using a highly toxic detergent: cetyltrimethylammonium bromide (CTAB). Thus, the removal of CTAB from the reaction mixture, and further stabilization of the surface of the AuNRs is required. In the present study, AuNRs were encapsulated in a multifunctional envelope-type nano device (AuNR-MEND) formed with an SS-cleavable and pH-activated lipid-like material...

OBJECTIVE: Periodontitis is characterized by local inflammation leading to tooth loss and severe destruction of alveolar bone. Raloxifene is a selective estrogen receptor modulator (SERM) that halts estrogen deficiency-induced systemic bone loss in postmenopausal osteoporosis without the side effects of cancer in breast and uterus. In this study, we examined the effects of raloxifene on alveolar bone mass in a mouse model with estrogen deficiency-induced periodontitis. METHODS: Periodontitis was induced by the injection of lipopolysaccharide (LPS) into the lower gingiva in ovariectomized (OVX) mice, and the alveolar bone and femur bone mineral density (BMD) were analyzed by dual-energy X-ray absorptiometry...

Drug-loaded magnetic nanoparticles were synthesized and used for the sequential delivery of the anti-resorptive agent zoledronic acid (Zol) and the cytotoxic drug doxorubicin (Dox) to breast cancer cells (MCF-7). Zol was attached to bare iron oxide nanoparticles (IONPs) via phosphonate coordination to form Z-NPs. The unbound imidazole of Zol was then used to complex the organic macrocycle CB[7] to obtain CZ-NPs. Dox was then complexed to the CZ-NPs to form the fully loaded particles (DCZ-NPs), which were stable in solution at 37 ºC and physiological pH (7...

BACKGROUND: Vimentin belongs to an intermediate filament (IF) family of proteins, mainly present in mesenchymal cells and has a crucial role in maintaining cellular integrity. Vimentin can induce epithelial to mesenchymal transition, and thus increase migration and invasion capacity of the cells. It has been shown to be a useful and reliable diagnostic and prognostic marker in several cancers including colon cancers, breast and hepatocellular cancers. Recent studies suggest that it may have a role in distant metastasis of non-small cell lung cancer (NSCLC) accounting for poor survival [1]...
