PURPOSE Constitutive activation of signal transducer and activator of transcription 3 (Stat3) protein has been observed in a wide variety of tumors, including breast cancer, and contributes to oncogenesis at least in part by prevention of apoptosis. In a study of 45 patients with high-risk breast cancer enrolled in a phase II neoadjuvant chemotherapy trial with docetaxel and doxorubicin, we eva...

Cell nuclei are like gated communities—quite selective about who gets in. And understandably so, because if the wrong proteins showed up at the wrong time and place, the consequences could be disastrous. The standard procedure for moving large molecules that cannot diffuse from the cytoplasm into the nucleus is to use the transport proteins known as karyopherins as escorts. How do karyopherins ...

Four hybrid polyoxometalate–porphyrin copolymer films were obtained by the electrooxidation of zinc-β-octaethylporphyrin (ZnOEP) or 5,15-ditolylporphyrin (H2T2P) in presence organosilyl functionalized Keggin-type POMs TBA3[PW11Si2O40C26H16N2] (abbreviated Py-PW11Si2-Py) and Dawson-type TBA6[P2W17Si2O62C26H16N2] Py-P2W17Si2-Py) bearing two remote pyridyl groups. The electropolymerization process...

Background: Despite evidence for the beneficial effects of probiotics and low-fat dairy products, to our knowledge, no study has compared the beneficial effect on weight loss of consuming a probiotic yogurt (PY) compared with a standard low-fat yogurt (LF) during a hypoenergetic program. Objective: We compared the effect of the PY with LF yogurt consumption on body weight and cardiometabolic ri...

In the title compound, C(24)H(25)N(3)S(2), the S-bound benzene rings have orthogonal [dihedral angle = 85.31 (9)°] and splayed [67.92 (11)°] orientations with respect to the pyrimidine ring; the dihedral angle between the benzene rings is 48.18 (12)°. The pentyl group has an extended all-trans conformation and lies to one side of the pyrimidine ring [the N(py)-C(py)-C(p)-C(p) torsion angle = -8...

The spin mixing conductance g↑↓ of a ferromagnetic and nonmagnetic (NM) layer characterizes the transport efficiency current through interface. Exploration relationship between structural parameters such as lattice orientation NM is critical to design effective spintronics devices. Here, two types single oriented Pt Ni81Fe19 (Py) was studied experimentally, with method pumping. obtained for (10...

BACKGROUND People who inject drugs (PWID) are at high risk of hepatitis C virus (HCV) infection. Trends in HCV incidence and associated risk factors among PWID recruited between 1996 and 2012 in Vancouver, Canada were evaluated. METHODS Data were derived from a long-term cohort of PWID in Vancouver. Trends in HCV incidence were evaluated. Factors associated with time to HCV infection were ass...

Novel p-tolylimido rhenium(V) complexes trans-(Cl,Cl)-[Re(p-NC6H4CH3)Cl2(py-2-COO)(PPh3)]·MeCN (1a), trans-(Cl,Cl)-[Re(p-NC6H4CH3)Cl2(py-2-COO)(PPh3)] (1b), trans-(Br,Br)-[Re(p-NC6H4CH3)Br2(py-2-COO)(PPh3)] (2), cis-(Cl,Cl)-[Re(p-NC6H4CH3)Cl2(py-2-COO)(PPh3)] (3), cis-(Br,Br)-[Re(p-NC6H4CH3)Br2(py-2-COO)(PPh3)]·H2O (4), trans-(Cl,Cl)-[Re(p-NC6H4CH3)Cl2(OMe)] (5) and trans-(Br,Br)-[Re(p-NC6H4CH3...

INTRODUCTION HIV controllers (HICs) experience relatively low-level viraemia and CD4 preservation without antiretroviral therapy (ART), but also immune activation that may predispose to adverse clinical events such as cardiovascular disease and hospitalization. The objective of this study was to characterize the rates and reasons for hospitalization among HICs and persons with medically control...
