<P>The primary objective of this multicenter, open-label, randomized, parallel, phase II selection trial was to compare the objective tumor response to biweekly (every 2 weeks) gemcitabine/paclitaxel, gemcitabine/carboplatin, and gemcitabine/cisplatin as first-line treatment for metastatic breast cancer.</P>

Present work aimed at studying the effect of montmorillonite (MMT) on dielectric and conductive properties of composites based on polymer/hafnium carbide (HfC) mother composite system. Polymer/HfC/MMT composite films based on double-filler modification strategy were prepared by solution cast. To obtain control group, binary polymer/HfC composite films were prepared. MMT ceramic had excellent insulation property, which could suppress interface leakage current and thus reduce dielectric loss of composites. Compared with binary system, ternary system could show better overall electric features including mildly reduced permittivity, obviously reduced dielectric loss and conductivity. Optimized ternary composite bearing 3 wt% HfC and 3 wt% MMT exhibited a high permittivity of 34, low dielectric loss of 0.33 and low conductivity of 5.5 × 10-7 S m-1 at 100 Hz. This research might enable the fabrication of advanced composite dielectrics.

Graphene Oxide Nanosheet-Composited Poly(N-isopropylacrylamide) Hydrogel for Cell Sheet Recovery

Cell sheet engineering technique has been applied to treat various tissues without the use of a traditional scaffold. To date, methods for the cell sheet harvesting depend mostly on grafted poly(N-isopropylacrylamide) (pNIPAAm) thin layers, while the native pNIPAAm hydrogel, which possibly presents the easiest way to prepare thermo-responsive materials, is not suitable for the cell sheet harvesting due to its low cell attachment. In this study, the graphene oxide (GO) nanosheet was utilized as an additive to enhance the bio-compatibility of the pNIPAAm hydrogel. Different concentrations of GO nanosheets were added to prepare GO/pNIPAAm composite hydrogels through the in-situ free radical polymerization with polyethylene glycol dimethacrylate (PEGDA) as a cross-linker. The results indicated that the physical properties of the composite hydrogels had little difference with that of the native pNIPAAm hydrogel. However, the cell attachment, proliferation and detachment behaviors on the composite hydrogel surface were greatly enhanced. Monkey fibroblast COS7 cells attached and proliferated better on the GO/pNIPAAm composite hydrogel, while intact COS7 cell sheets could be harvested from the composite hydrogels by simply lowering the temperature. In contrast, the cells appeared as clusters on the native pNIPAAm hydrogel. Furthermore, when HeLa and COS7 cells were seeded successively onto the micropatterned GO/pNIPAAm hydrogel, there could be the formation of a patterned HeLa/COS7 cell layer. The geometrically patterned GO/pNIPAAm hydrogel may provide an easy-to-prepare material for releasing patterned cell sheets compared to the specific cell-adhesive proteins reported to make patterned cell layers.

<B>Purpose</B><P>Effective treatment options for patients with metastatic breast cancer resistant to anthracyclines and taxanes are limited. Ixabepilone has single-agent activity in these patients and has demonstrated synergy with capecitabine in this setting. This study was designed to compare ixabepilone plus capecitabine versus capecitabine alone in anthracycline-pretreated or -resistant and taxane-resistant locally advanced or metastatic breast cancer.</P><B>Patients and Methods</B><P>Seven hundred fifty-two patients were randomly assigned to ixabepilone 40 mg/m<SUP>2</SUP>intravenously on day 1 of a 21-day cycle plus capecitabine 2,000 mg/m<SUP>2</SUP>orally on days 1 through 14 of a 21-day cycle, or capecitabine alone 2,500 mg/m<SUP>2</SUP>on the same schedule, in this international phase III study. The primary end point was progression-free survival evaluated by blinded independent review.</P><B>Results</B><P>Ixabepilone plus capecitabine prolonged progression-free survival relative to capecitabine (median, 5.8 v 4.2 months), with a 25% reduction in the estimated risk of disease progression (hazard ratio, 0.75; 95% CI, 0.64 to 0.88; P = .0003). Objective response rate was also increased (35% v 14%; P < .0001). Grade 3/4 treatment-related sensory neuropathy (21% v 0%), fatigue (9% v 3%), and neutropenia (68% v 11%) were more frequent with combination therapy, as was the rate of death as a result of toxicity (3% v 1%, with patients with liver dysfunction [≥ grade 2 liver function tests] at greater risk). Capecitabine-related toxicities were similar for both treatment groups.</P><B>Conclusion</B><P>Ixabepilone plus capecitabine demonstrates superior efficacy to capecitabine alone in patients with metastatic breast cancer pretreated or resistant to anthracyclines and resistant to taxanes.</P>

Light intensity and quality affect photosynthesis, plant morphology, and the synthesis of primary and secondary metabolites. Dysosma versipellis (Hance) M. Cheng is an endangered species endemic to China, and a highly valued medicinal and ornamental plant. In this study, we discuss the effects of different light spectrums conferred by colored plastic films on photosynthesis and the contents of active ingredients of D. versipellis. D. versipellis plants were cultured for 90 days under white, red, yellow, or blue film. The blue film treatment generally increased the chlorophyll content, photosynthetic rate (Pn), maximal photochemical efficiency of PSII (Fv/Fm), actual photochemical efficiency of PSII (ФPSII), photochemical quenching (qP), and the podophyllotoxin content of the rhizomes. The blue film treatment also decreased the maximum net photosynthetic rate (Amax), apparent photosynthetic quantum efficiency (AQY), and podophyllotoxin contents of the stems. The yellow film treatment resulted in a decline of the Amax, AQY, Fv/Fm, ФPSII, qP, chlorophyll contents, and podophyllotoxin contents of the leaves and rhizomes; however, the light compensation point (LCP), light saturation point, and minimum fluorescence (Fo) were increased. There were no significant differences in chlorophyll content, Amax, LCP, AQY, Fv/Fm, ФPSII, or qP between the white and red film treatments. These results suggest that in D. versipellis, blue film treatments promote photosynthesis and the accumulation of podophyllotoxin, while yellow film treatments inhibit photosynthesis and the accumulation of podophyllotoxin.
