Synergistic Effect of Saccharin and Caffeine on Antiproliferative Activity in Human Ovarian Carcinoma Ovcar-3 Cells.

The purpose of this study was to confirm the antiproliferative and apoptotic induction potential of a saccharin and caffeine combination in ovarian cancer cells. The cell line used was Ovcar-3, and the cell viability was measured through a WST-8 assay, while a Chou-Talalay assay was used to confirm the synergistic effect of saccharin and caffeine on the ovarian cancer cells. A clonogenic assay, annexin V-FITC/PI-PE double-staining, and RT-PCR were performed to confirm the expression of genes that induce colony formation, cell viability, and apoptosis in ovarian cancer cells treated with the saccharin-caffeine combination.

Development of a Simple Direct and Hot-Start PCR Using -Expressing DNA Polymerase.

DNA polymerases have played an important role in molecular biology for several years and are frequently used for polymerase chain reaction (PCR); hence, there is an increasing interest in developing a convenient method for preparing DNA polymerase for routine use in laboratories. We developed a method using () that expresses thermostable DNA polymerase directly in the PCR without purification. The gene was transformed into and expressed.

Transcriptome and Proteome Co-Profiling Offers an Understanding of Pre-Harvest Sprouting (PHS) Molecular Mechanisms in Wheat ().

Microstructural and Texture Evolution in Pure Niobium during Severe Plastic Deformation by Differential Speed Rolling.

The evolution of the microstructure and texture in body-centered cubic (BCC) niobium (Nb) during conventional rolling and high-ratio differential rolling (HRDSR) at room temperature were compared. More effective grain refinement of the initial microstructure through continuous dynamic recrystallization (CDRX) occurred in the samples processed by HRDSR, but the overall degree of grain refinement was small, despite having undergone severe plastic deformation due to the low rate of CDRX. CDRX more preferentially proceeded on {111} γ-fiber grains than on {001}<110> α-fiber grains.

We report a non-covalent loading of ginsenoside compound K (CK) onto our previously reported gold nanoparticles (DCY51-AuCKNps) through one-pot biosynthesis using a probiotic Lactobacillus kimchicus DCY51 isolated from Korean kimchi. The ginsenoside-loaded gold nanoparticles were characterized by various analytical and spectroscopic techniques such as field emission transmission electron microscopy (FE-TEM), energy-dispersive X-ray (EDX) spectroscopy, elemental mapping, X-ray powder diffraction (XRD), selected area electron diffraction (SAED), Fourier-transform infrared (FTIR) spectroscopy and dynamic light scattering (DLS). Furthermore, drug loading was also determined by liquid chromatography-mass spectrometry (LC-MS).

Influence of Post-Heat Treatment of ZnO:Al Transparent Electrode for Copper Indium Gallium Selenide Thin Film Solar Cell.

Copper indium gallium selenide (CIGS) thin film solar cells have been regarded as a candidate for energy conversion devices owing to their high absorption coefficient, high temperature stability, and low cost. ZnO:Al thin film is commonly used in CIGS solar cells as a window layer. In this study, ZnO:Al films were deposited on glass under various post-heat temperature using RF sputtering to observe the characteristics of ZnO:Al films such as Hall mobility, carrier concentration, and resistivity; subsequently, the ZnO:Al films were applied to a CIGS solar cell as a window.

Alveolar Bone Protective Effect of Hiziki Extracts on the Progression of Periodontitis.

The purpose of this study was to evaluate the effects of hiziki extract on alveolar bone loss, inflammation, and osteo-biomarker expression in hPDL cells (10, 50, 100 μg/ml final concentrations in culture medium) and on a ligature-induced periodontitis rat model (50, 100, 200 mg/kg with oral administration). Hiziki extract increased alkaline phosphatase activity and mineralized nodule formation in hPDL cell. In western blot analysis, hiziki extract resulted in increased expression of osteoblast markers, including transforming growth factor beta (TGF-β), SMAD anchor for receptor activation (SARA) and runt-related transcription factor 2 (RUNX2) in hDPL cells.

Borago officinalis L. attenuates UVB-induced skin photodamage via regulation of AP-1 and Nrf2/ARE pathway in normal human dermal fibroblasts and promotion of collagen synthesis in hairless mice.

Ultraviolet B (UVB) irradiation is regarded as the main cause of skin photodamage. After exposure to UVB irradiation, collagen degradation is accelerated by upregulation of matrix metalloproteinases (MMPs), and collagen synthesis is decreased via downregulation of transforming growth factor (TGF)-β1 signaling. Borago officinalis L.

Antiaging effects of the mixture of and in human dermal fibroblasts and healthy human skin.

Background: Human skin undergoes distinct changes throughout the aging process, based on both intrinsic and extrinsic factors. In a process called photoaging, UVB irradiation leads to upregulation of matrix metalloproteinase-1, which then causes collagen degradation and premature aging. Mixtures of medicinal plants have traditionally been used as drugs in oriental medicine.

Dietary Foeniculum vulgare Mill extract attenuated UVB irradiation-induced skin photoaging by activating of Nrf2 and inhibiting MAPK pathways.
