oxalis tuberosa/breast neoplasms

BACKGROUND Breast cancer is a major cause of morbidity, mortality, and medical expenditures among women in Canada. Essiac (Resperin Canada Limited, Waterloo, Ontario, Canada), a blend of at least four herbs (burdock root [Arctium lappa], Indian rhubarb [Rheum palmatum], sheep sorrel [Rumex

Although estrogens have been identified as key endocrine hormones in the control of early mitogenesis and development in the mammary gland, local control of cell proliferation during ductal morphogenesis may be regulated by polypeptides such as TGF-alpha or TGF-beta. Many breast tumors are estrogen

While estrogens are suspected risk factors for epithelial ovarian cancer (OCa), progesterone (P4) has been shown to exert protective effects. The biological actions of P4 in target cells are mediated by progesterone receptors (PRs) that exist principally as A- and B-isoforms. We observed

Among hydroxycinnamic acids, caffeic, ferulic and p-coumaric acids have received considerable attention due to their biological activities. However, studies related to the biological activities of o-coumaric acid (OCA) are limited. In this regard, this study was designed to determine the

Simple, rapid, and efficient cell viability assays play a fundamental role in much of biomedical research, including cell toxicology investigations and antitumor drug screening. Here, we demonstrate for the first time a rapid and label-free cell viability assay using THz spectroscopy in combination

Chiral enantiomers [Cu(phen)(l-ser)(H2O)]NO31 and [Cu(phen)(d-ser)(H2O)]NO32 (ser = serinato) underwent aldol-type condensation with formaldehyde, with retention of chirality, to yield their respective enantiomeric ternary copper(ii) complexes, viz. l- and d-[Cu(phen)(OCA)(H2O)]NO3·xH2O (3 and 4;

We developed camptothecin (CPT)-conjugated, core-cross-linked (CCL) micelles that are subject to redox-responsive cleavage of the built-in disulfide bonds, resulting in disruption of the micellar structure and rapid release of CPT. CCL micelles were prepared via coprecipitation of

Robust efficiency for cytosolic small interfering RNA (siRNA) delivery is of great importance for effective gene therapy. To significantly improve the cytosolic siRNA delivery, a "one-pot modular assembly" strategy is developed to assemble a triple-play enhanced cytosolic siRNA delivery
