In this study, a mechanical stacking technique has been used to bond together the GaInP/GaAs and poly-silicon (Si) solar wafers. A GaInP/GaAs/poly-Si triple-junction cell mechanically stacked using low-temperature bonding process which involves micro metal balls on line high-optical-transmission spin-coated glue material. Current–voltage measurements of cells have carried out at room temperatur...

Background: Previous studies have suggested that BRCA1 dysregulation has been shown to have a role in triple-negative phenotypic manifestation. However, differences of BRCA1 expression, as a tumor suppressor gene, have rarely been investigated between luminal and triple-negative breast tumors. Therefore, the present study attempted to compare the BRCA1 expression in triple-negative with lu...

A surface plasmonic waveguide made of metal–insulator–metal (MIM) capable generating triple Fano resonances is proposed and numerically investigated for multi-biological parameter sensing as well tunable slow light. The up a bus with silver baffle, square split-ring cavity center (SSRCSC), circular ring (CRCSC). Based on the resonances, human blood temperature plasma concentration are measured ...

eradication rate of helicobacter pylori using low dose furazolidone in triple & quadruple therapies versus metronidazol in triple therapy in du patients

Colorectal cancer (CRC) is one of the major causes of cancer deaths in the world. 5-fluorouracil (5-FU) -based chemotherapy is a common choice for patients with CRC; unfortunately, the benefit is rather limited due to the acquisition of drug resistance. Therefore, the alternative therapeutic strategies are required. The activation of autophagic mechanism was considered as the main cause of the ...

Herein we report the synthesis of new water-soluble vitamin B12 prodrugs bearing metal complexes at the β-upper side of the cobalt center. A total of three derivatives with the general design {Co-C[triple bond, length as m-dash]C-bpy-M}, where M represents a cytotoxic metal complex, were prepared and tested for their cytotoxicity against MCF-7 breast cancer cells. The choice of the metal was or...

We show that a triple-layer metal-insulator-metal (MIM) structure has spectrally selective IR absorption, while an ultra-thin metal film has non-selective absorption in the near infrared wavelengths. Both sub-wavelength scale structures were implemented with an ultra-thin 6 nm Cr top layer. MIM structure was demonstrated to have near perfect absorption at λ = 1.2 μm and suppressed absorption at...

The phase diagram of zirconium metal has been studied using synchrotron X-ray diffraction and time-of-flight neutron scattering at temperatures and pressures up to 1273 K and 17 GPa. The equilibrium phase boundary of the a–u transition has a dT/dP slope of 473 K/GPa, and the extrapolated transition pressure at ambient temperature is located at 3.4 GPa. For the u–b transition, the phase boundary...

Transcriptional regulation of the sodA gene, a member of the soxRS regulon encoding the manganese-containing superoxide dismutase (MnSOD; superoxide:superoxide oxidoreductase, EC 1.15.1.1) of Escherichia coli, was examined in a variety of regulatory mutants. Diamide, an oxidant that causes the anaerobic biosynthesis of the MnSOD polypeptide and also facilitates insertion of manganese at the act...
