Background: α-Mangostin (αMG) is extracted from Garcinia mangostana Linn and exerts antiproliferative activities. Although several researches on αMG were performed using cell monolayers, the in vitro pharmacological effects on 3D cancer models have never been investigated. Aim of the present study was to find new anticancer properties of αMG by evaluating the changes that this compound provokes in multicellular tumour spheroids (MCTSs). Methods: MCTSs were generated from MDA-MB-231 and MCF-7 breast tumour cell lines and then treated with 0...

PURPOSE: Breast cancer is the second most frequently diagnosed cancer and is considered as the main cause of cancer related death in females. It is estimated that about one-third of women with breast cancer develop metastases and eventually die of this disease. The main treatment options for breast cancer include surgical interventions followed by chemotherapy, hormonotherapy or radiation. However, the side effects associated with the treatment of breast cancer negatively affects the quality of patient's life...

It is important to understand the history of breast cancer screening to better understand the continuing effort to reduce access to screening. Since the randomized, controlled trials have shown a statistically significant mortality reduction for women ages 40-74, the appropriate threshold for initiating screening is age 40 with no data to support the use of the age of 50 as a threshold for screening. All women are at risk for developing breast cancer and all women should have access to screening.

Increased uptake of glucose, a general hallmark of malignant tumors, leads to an accumulation of intermediate metabolites of glycolysis. We investigated whether the high supply of these intermediates promotes their flow into UDP-sugars, and consequently into hyaluronan, a tumor-promoting matrix molecule. We quantified UDP-N-Acetylglucosamine (UDP-GlcNAc) and UDP-glucuronic acid (UDP-GlcUA) in human breast cancer biopsies, the levels of enzymes contributing to their synthesis, and their association with the hyaluronan accumulation in the tumor...

Adjuvant radiotherapy after breast-conserving surgery has been an important component of the standard of care for early breast cancer. Improvements in breast cancer care have resulted in a substantial reduction in local relapse rates over recent decades. Although the proportional benefits of adjuvant radiotherapy are similar for different prognostic risk groups of patients, the absolute benefits depend on the risk of relapse and therefore vary considerably between prognostic groups. Radiotherapy is not without risk and for some patients at very low risk of relapse the risks of radiotherapy may outweigh the benefit, leading to potential overtreatment...

BACKGROUND: Cryolipolysis is a non-invasive method of body shaping that has been used for male pseudogynecomastia. However, traditional vacuum suction cryolipolysis requires a minimum pinchable fat layer which may not always be present in this area. OBJECTIVE: To evaluate the efficacy and safety of a conformable surface cryolipolysis applicator for the reduction of male pseudogynecomastia. MATERIALS AND METHODS: Ten male subjects with pseudogynecomastia received two cycles of cryolipolysis to the breast 6 weeks apart...

BACKGROUND: Hypermethylation is observed in the promoter regions of suppressor genes in the tumor cancer cells. Reactivation of these genes by demethylation of their promoters is a prospective strategy of the anticancer therapy. Previous experiments have shown that symmetric dimeric bisbenzimidazoles DBP(n) are able to block DNA methyltransferase activities. It was also found that DBP(n) produces a moderate effect on the activation of total gene expression in HeLa-TI population containing epigenetically repressed avian sarcoma genome...

INTRODUCTION: Preoperative planning is an essential prerequisite for the success of plastic surgery. In procedures such as breast reduction, freehand drawings may be associated with a number of challenges during the determination of axes vertical and parallel to the surgical site. Furthermore, many procedures involve subjective maneuvers, such as attempts aimed at positioning both nipples on the same line and transferring nipple-areola complexes in a well-matched manner. Our newly designed instrument, that is, the goniometer (TG), aims to ensure metric measurements appropriate for the axes, and it may also be used in circumstances that require angle measurements...

PURPOSE: Breast cancer is the leading cause of cancer mortality in women worldwide. With medical advances, metastatic breast cancer (MBC) patients often live for years with many symptoms that interfere with activities. However, there is a paucity of efficacious interventions to address symptom-related suffering and functional interference. Thus, this study examined the feasibility and preliminary efficacy of telephone-based acceptance and commitment therapy (ACT) for symptom interference with functioning in MBC patients...

The iron metabolism of malignant cells, which is altered to ensure higher acquisition and utilization, motivates the investigation of iron chelation strategies in cancer treatment. In a prochelation approach aimed at increasing intracellular specificity, disulfide reduction/activation switches are incorporated on iron-binding scaffolds resulting in intracellularly activated scavengers. Herein, this strategy is applied to several tridentate donor sets including thiosemicarbazones, aroylhydrazones and semicarbazones...

Activated platelets promote the proliferation and metastatic potential of cancer cells. Platelet activation is largely mediated through ADP engagement of purinergic P2Y12 receptors on platelets. We examined the potential of the reversible P2Y12 inhibitor ticagrelor, an agent used clinically to prevent cardiovascular and cerebrovascular events, to reduce tumor growth and metastasis. In vitro, MCF-7, MDA-MB-468, and MDA-MB-231 human mammary carcinoma cells exhibited decreased interaction with platelets treated with ticagrelor compared to untreated platelets...

Functional neuroimaging has emerged as attractive option for characterizing pain states complementing behavioral readouts or clinical assessment. In particular resting-state fMRI (rs-fMRI) enables monitoring of functional adaptations across the brain, e.g. in response to chronic nociceptive input. We have used rs-fMRI in a mouse model of chronic pain from breast cancer derived tibial bone metastases to identify pain-induced alterations in functional connectivity (FC). Combined assessment of behavioral readouts allowed defining a trajectory as model function for extracting pain-specific FC changes from the fMRI data reflective of a chronic pain state...

Mastectomies for both cancer resection and risk reduction are becoming more common. Existing chest wall irregularities are found in these women presenting for breast reconstruction after mastectomy and can pose reconstructive challenges. Women who desired breast reconstruction after mastectomy were evaluated preoperatively for existing chest wall irregularities. Case reports were selected to highlight common irregularities and methods for improving cosmetic outcome concurrently with breast reconstruction procedures...

Post-partum haemorrhage (PPH) remains the major cause of maternal death worldwide, with the overwhelming majority of bleeding deaths occurring in low income countries. These bleeding deaths occur due to a complex network of biological and socioeconomic factors, including changes to haemostasis and fibrinolysis during pregnancy. Tranexamic acid (TxA) has been shown to reduce death in bleeding trauma patients safely and is effective in reducing bleeding in surgical patients, however its role in PPH has been less well established...

Active efflux transport of glucuronides out of cells is a critical process in elimination of drugs and food-derived compounds. Wushanicaritin, a natural polyphenol from Epimedium species, has shown many biological activities. However, the transporters responsible for excretion of wushanicaritin glucuronides still remain undefined. Herein, chemical inhibitors (Ko143, MK571, dipyridamole and leukotriene C4) and single stable knocked-down efflux transporters (BCRP, MRP1, MRP3 and MRP4) were used to determine the contributions of efflux transporters to glucuronide efflux and cellular glucuronidation in UGT1A1-overexpressing HeLa cells (HeLa1A1)...

Early detection of breast cancers by mammography in conjunction with adjuvant therapy has contributed to reduction in breast cancer mortality. Mammography remains the "gold-standard" for breast cancer screening but is limited by tissue superposition. Digital breast tomosynthesis and more recently, dedicated breast computed tomography have been developed to alleviate the tissue superposition problem. However, all of these modalities rely upon x-ray attenuation contrast to provide anatomical images, and there are ongoing efforts to develop and clinically translate alternative modalities...

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and clinically relevant side effect of chemotherapy. Approximately 50% of all leukemia, lymphoma, colorectal- and breast cancer patients are affected. CIPN is induced by neurotoxic chemotherapeutic agents and can manifest with sensory and/or motor deficits. It is associated with significant disability and poor recovery. Common symptoms include pain, altered sensation, reduced or absent reflexes, muscle weakness, reduced balance control and insecure gait...
