BACKGROUND: More than 85% of contemporary lactating women in the United States express their milk at least sometimes. Some produce milk exclusively through pumping. We characterized women who pumped but never fed at the breast and compared their infant feeding practices with those of women who fed at the breast with or without pumping. SUBJECTS AND METHODS: Study participants were those delivered at Ohio State University Wexner Medical Center in 2011 and completed a questionnaire at 12 months postpartum (n = 478)...

Many physicians, midwives and lactation consultants still believe that yeasts (particularly Candida spp.) play an important role as an agent of nipple and breast pain despite the absolute absence of scientific proofs to establish such association. In this context, the objective of this study was to investigate the microorganisms involved in sore nipples and/or painful "shooting" breastfeeding by using a variety of microscopy techniques, as well as culture-dependent and-independent identification methods. Initially, 60 women (30 diagnosed as suffering "mammary candidiasis" and 30 with no painful breastfeeding) were recruited to elucidate the role of their pumps on the milk microbial profiles...

Multidrug resistance (MDR) contributes to failure of chemotherapy. We here show that biodegradable polymeric nanogels are able to overcome MDR via folic acid targeting. The nanogels are based on hydroxyethyl methacrylamide-oligoglycolates-derivatized poly(hydroxyethyl methacrylamide-co-N-(2-azidoethyl)methacrylamide) (p(HEMAm-co-AzEMAm)-Gly-HEMAm), covalently loaded with the chemotherapeutic drug doxorubicin (DOX) and subsequently decorated with a folic acid-PEG conjugate via copper-free click chemistry. pH-Responsive drug release is achieved via the acid-labile hydrazone bond between DOX and the methacrylamide polymeric network...

For millennia, the word "breastfeeding" has meant feeding an infant at his/her own mother's breast. With the recent introduction of high-efficiency breast pumps, other possibilities are now widely used, including feeding an infant his/her own mother's milk from a cup or bottle. This milk may be recently pumped or stored for a short or long time. Infants also may be fed another mother's milk. As a result, the use of the term "breastfeeding" to describe these different behaviors now inhibits clear communication among and between healthcare providers, researchers, mothers, and members of the lay public...

Multidrug resistance (MDR) is a major hindrance to curative chemotherapy of various human malignancies. Hence, novel chemotherapeutics must be evaluated for their recognition by MDR efflux transporters. Herein we explored the cytotoxic activity of synthetic tubulysin B (Tub-B, EC1009) derivatives (Tub-B-hydrazide/EC0347 and Tub-B bis-ether/EC1820), and their recognition by the MDR efflux transporters P-glycoprotein 1 (P-gp), multidrug resistance-associated protein 1 (MRP1) and breast cancer resistance protein (BCRP)...

BACKGROUND: In-hospital experiences among women with gestational diabetes mellitus (GDM) could impact breastfeeding success. We sought (1) to determine changes in the prevalence of hospital breastfeeding experiences between 2004-2008 and 2009-2011 among women with GDM and women without diabetes; (2) to determine whether GDM is associated with higher occurrence of experiencing Baby-Friendly hospital practices because of their known higher rates of breastfeeding difficulties. MATERIALS AND METHODS: Data from the 2004 to 2011 Pregnancy Risk Assessment Monitoring System, a survey of women with a recent live birth from 16 states and New York City, were used based on inclusion of an optional survey question about hospital breastfeeding experiences...

Calcification of the breast is often an outward manifestation of underlying molecular changes that drive carcinogenesis. Up to 50% of all non-palpable breast tumors and 90% of ductal carcinoma in situ present with radiographically dense mineralization in mammographic scans. However, surprisingly little is known about the molecular pathways that lead to microcalcifications in the breast. Here, we report on a rapid and quantitative in vitro assay to monitor microcalcifications in breast cancer cell lines, including MCF7, MDA-MB-231 and Hs578T...

BACKGROUND: Very little is known about the breastfeeding experience of mothers of infants born with congenital anomalies and cared for in the neonatal intensive care unit (NICU). Often, studies related to breastfeeding and lactation in the NICU setting are focused on the mothers of late preterm, preterm, low-birth-weight, and very-low-birth-weight infants. Congenital diaphragmatic hernia (CDH) is an anatomic malformation of the diaphragm and affects 1 in every 2,000 to 4,000 live births...

Several new therapeutic options emerged recently to treat metastatic melanoma; however, the high frequency of intrinsic and acquired resistance among patients shows a need for new therapeutic options. Previously, we identified the plasma membrane Ca(2+) ATPase 4b (PMCA4b) as a metastasis suppressor in BRAF-mutant melanomas and found that mutant BRAF inhibition increased the expression of the pump, which then inhibited the migratory and metastatic capability of the cells. Earlier it was also demonstrated that histone deacetylase inhibitors (HDACis) upregulated PMCA4b expression in gastric, colon, and breast cancer cells...

A series of derivatives were synthesized and studied with the aim to investigate the structure-activity relationships of the two P-glycoprotein (P-gp) modulators elacridar and tariquidar. Then different aryl substituted amides were inserted and to explore the effects of varying the amide function, the corresponding isosteric ester derivatives and some alkylamine analogues were synthesized. The new compounds were studied to evaluate their P-gp interaction profile and selectivity towards the two other ABC transporters, Multidrug-Resistance-associated Protein-1 (MRP-1) and Breast Cancer Resistance Protein (BCRP)...

INTRODUCTION: Breastfeeding rates are virtually unknown for teen mothers whose low-birth-weight (LBW; <2500 gm) infants are hospitalized in the neonatal intensive care unit (NICU). The objective was to examine the infant feeding experiences, goals, and outcomes of teen mothers of LBW infants. METHODS: We conducted a multimethod study using a qualitative research design, survey, and infant medical records. The primary data source was individual interviews conducted with teen mothers of LBW infants hospitalized in a tertiary NICU...

Microtubules are cellular targets for a variety of anticancer therapies because of their critical function in mitosis. Taxol belongs to a class of microtubule targeting agents that suppresses microtubule dynamics and interferes with the functioning of the mitotic spindle, thereby effectively blocking cell cycle progression of rapidly proliferating tumor cells. Despite its antitumor activity, drug resistance remains a common obstacle in improving its overall clinical efficacy. Previous studies have shown that the expression of a specific β-tubulin isotype, βIII-tubulin/TUBB3, is dysregulated in drug-refractory tumors...

FXYD5 is a Na(+)-K(+)-ATPase regulator, expressed in a variety of normal epithelia. In parallel, it has been found to be associated with several types of cancer and effect lethal outcome by promoting metastasis. However, the molecular mechanism underlying FXYD5 mediated invasion, was has not yet been identified. In this study, using in vivo 4T1 murine breast cancer model, we found that FXYD5 specific shRNA significantly inhibited lung cancer metastasis, without having a substantial effect on primary tumor growth...

Mycobacterium tuberculosis (MTB) is notorious for persisting within host macrophages. Efflux pumps decrease intracellular drug levels, thus fostering persistence of MTB during therapy. Isoniazid (INH) and pyrazinamide (PZA) are substrates of the efflux pump breast cancer resistance protein-1 (BCRP-1), which is inhibited by chloroquine (CQ). In this study, BCRP-1 was found to be expressed on macrophages of human origin and on foamy giant cells at the site of MTB infection. In the current in vitro study, interferon-gamma (IFNγ) increased the expression of BCRP-1 in macrophages derived from the human monocytic leukaemia cell line THP-1...

It is known that V-ATPases (vacuolar H+-ATPase) are involved in breast cancer growth and metastasis. Part of this action is similar to their role in osteoclasts, where they're involved in extracellular acidification and matrix destruction; however, the roles of their subunits in cancer cell proliferation, signaling, and other pro-tumor actions are not well established. Analysis of TCGA data shows that V-ATPase subunit Atp6v1c1 is overexpressed or amplified in 34% of human breast cancer cases, with a 2-fold decrease in survival at 12 years...

The combination of methotrexate with epidermal growth factor receptor (EGFR) recombinant antibody, cetuximab, is currently being investigated in treatment of head and neck carcinoma. As methotrexate is cleared by renal excretion, we studied the effect of cetuximab on renal methotrexate handling. We used human conditionally immortalized proximal tubule epithelial cells overexpressing either organic anion transporter 1 or 3 (ciPTEC-OAT1/ciPTEC-OAT3) to examine OAT1 and OAT3, and the efflux pumps breast cancer resistance protein (BCRP), multidrug resistance protein 4 (MRP4), and P-glycoprotein (P-gp) in methotrexate handling upon EGF or cetuximab treatment...
