Structure Revision of Anti-Inflammatory Indole Alkaloids with a 1,2-Benzisoxazole Ring.

()- and ()-2-(benzo[]isoxazol-3-yl)-2-ethylindolin-3-one [(±)-] were previously isolated from NIRAM, a natural blue dye from , and their structures were initially proposed to possess a 1,2-benzisoxazole ring. In this study, the structures of (±)- were revised to have an indole-anthranilic acid fused tetracyclic ring rather than the 1,2-benzisoxazole ring by reanalysis of one-dimensional (1D) and two-dimensional (2D) NMR followed by density functional theory (DFT) chemical shift calculation, DP4+ technique, and ECD simulation.

Extraction of Green Tea Phenolics Using Water Bubbled with Gases.

Water was bubbled with gases including nitrogen (N ), oxygen (O ), hydrogen (H ), carbon dioxide (CO ), and air for 10 min and phenolics from green tea leaves were extracted using the prepared gas-bubbled water. To retain the gases in water, the extraction conditions were maintained in an air-tight container at room temperature under magnetic stirring. Radical scavenging ability, total phenolic content, and phenolic profiles of the extracts were analyzed, and gas-bubbled water was examined to explain the differences in phenolic contents.

Addition of Sesamol Increases the Oxidative Stability of Beeswax Organogels and Beef Tallow Matrix Under UV Light Irradiation and Thermal Oxidation.

To enhance the oxidative stability of organogels made from canola oil, 40 ppm sesamol was added to beeswax-based organogels stored under ultraviolet (UV) light irradiation and 60 or 100 °C thermal oxidation conditions. To study the practical application of organogels as animal fat substitutes, beef tallow was mixed with organogels and their oxidative stability was determined under oxidative stress conditions. Without sesamol addition, the organogels and beef tallow with organogel oxidized rapidly under UV irradiation and thermal oxidation.

Electrically Conductive Adhesives and the Shingled Array Cell for High Density Modules.

The shingled array of solar cells has the advantages of a larger active area and smaller current density than conventional solar cells. Because the power loss is mainly driven by the decrease in current density, this new method has the benefit of increasing module power with the same installed area as used in other methods. As the electrically conductive adhesive (ECA), CA3556HF was chosen and characterized by analysis of reflectance and sheet resistance.

Effects of Hydrogen-Donating or Metal-Chelating Antioxidants on the Oxidative Stability of Organogels Made of Beeswax and Grapeseed Oil Exposed to Light Irradiation.

Unlabelled: To enhance the oxidative stability of organogels made from grapeseed oil, the antioxidant effects of sesamol, α-tocopherol, β-carotene, ethylenediaminetetraacetic acid (EDTA), and citric acid were determined in beeswax-based organogels stored under light or in the dark conditions at 25 °C. Without the addition of antioxidants, the organogels rapidly oxidized under light irradiation but not during storage in the dark. Sesamol showed the highest antioxidant activity at concentrations of 10 to 40 ppm, whereas the other compounds exhibited no antioxidant activity at 10 ppm.

Cilengitide combined with standard treatment for patients with newly diagnosed glioblastoma with methylated MGMT promoter (CENTRIC EORTC 26071-22072 study): a multicentre, randomised, open-label, phase 3 trial.

Background: Cilengitide is a selective αvβ3 and αvβ5 integrin inhibitor. Data from phase 2 trials suggest that it has antitumour activity as a single agent in recurrent glioblastoma and in combination with standard temozolomide chemoradiotherapy in newly diagnosed glioblastoma (particularly in tumours with methylated MGMT promoter). We aimed to assess cilengitide combined with temozolomide chemoradiotherapy in patients with newly diagnosed glioblastoma with methylated MGMT promoter.

Chinese yam extracts containing β-sitosterol and ethyl linoleate protect against atherosclerosis in apolipoprotein E-deficient mice and inhibit muscular expression of VCAM-1 in vitro.

Atherosclerosis is a chronic inflammatory disease, which is associated with increased expression of adhesion molecules and monocyte recruitment into the arterial wall. This study evaluated whether hexane extracts from the edible part (DB-H1) or bark region (DB-H2) of Dioscorea. batatas Decne have anti-atherosclerotic properties in vivo and in vitro experiments.

Apple peel and carboxymethylcellulose-based nanocomposite films containing different nanoclays.

Unlabelled: Biodegradable packaging films were developed from polymeric blends of apple peel powder (APP) and carboxymethylcellulose (CMC), into which different nanoclays were incorporated to produce a nanocomposite film. After first estimating the barrier and mechanical properties of 4 different biopolymer films (CMC, methylcellulose, gelatin, and polylactide), CMC was chosen as the best film-forming solution. Three different nanoclays (Cloisite Na(+) , 30B, and 20A) were subsequently dispersed in a CMC film solution to improve the barrier and physical properties of the final CMC nanocomposite films.

Effects of roasting conditions on the changes of stable carbon isotope ratios (δ13 C) in sesame oil and usefulness of δ13 c to differentiate blended sesame oil from corn oil.

Differentiating blended sesame oils from authentic sesame oil (SO) is a critical step in protecting consumer rights. Stable carbon isotope ratios (δ(13) C), color, fluorescence intensity, and fatty acid profiles were analyzed in SO prepared from sesame seeds with different roasting conditions and in corn oil blended with SO. Sesame seeds were roasted at 175, 200, 225, or 250 °C for 15 or 30 min at each temperature.

Bone marrow cells repair cigarette smoke-induced emphysema in rats.

The therapeutic potential of stem cells in chronic obstructive pulmonary disease is not well known although stem cell therapy is effective in models of other pulmonary diseases. We tested the capacities of bone marrow cells (BMCs), mesenchymal stem cells (MSCs), and conditioned media of MSCs (MSC-CM) to repair cigarette smoke-induced emphysema. Inbred female Lewis rats were exposed to cigarette smoke for 6 mo and then received BMCs, MSCs, or MSC-CM from male Lewis rats.

Expression of endothelial nitric oxide synthase in developing rat kidney.

Endothelium-derived nitric oxide (NO) is synthesized within the developing kidney and may play a crucial role in the regulation of renal hemodynamics. The purpose of this study was to establish the expression and intrarenal localization of the NO-synthesizing enzyme endothelial NO synthase (eNOS) during kidney development. Rat kidneys from 14 (E14)-, 16 (E16)-, 18 (E18)-, and 20-day-old (E20) fetuses and 1 (P1)-, 3 (P3)-, 7 (P7)-, 14 (P14)-, and 21-day-old (P21) pups were processed for immunocytochemical and immunoblot analysis.
