TL;DR: The photocatalytic reaction of o-methylbenzoic acid under the influence of pH values, anion additives and the varieties of titanium dioxide was found to be apparent first-order following Langmuir-Hinshelwood model and the reaction was faster with lowering pH.

TL;DR: In this paper, near-ultraviolet nitride-based light-emitting diodes (LEDs) with peak emission wavelengths around 410 nm were fabricated onto c-face patterned sapphire substrates (PSS).
Abstract: Near-ultraviolet nitride-based light-emitting diodes (LEDs) with peak emission wavelengths around 410 nm were fabricated onto c-face patterned sapphire substrates (PSS). It was found that the electroluminescence intensity of the PSS LED shown 63% larger than that of the conventional LED. For a typical lamp-form PSS LED operating at a forward current of 20 mA, the output power and external quantum efficiency were estimated to be 10.4 mW and 14.1%, respectively. The improvement in the light intensity could be attributed to the decrease of threading dislocations and the increase of light extraction efficiency in the horizontal direction using a PSS.

TL;DR: It is demonstrated that OA and UA induce apoptosis in HuH7 cells through a mitochondria-mediated pathway and downregulation of XIAP.
Abstract: Oleanolic acid (OA) and ursolic acid (UA) are commonly found in plants and herbs and have been reported to possess hepatoprotective, anti-inflammatory and anticancer activities. In the present study, the effects of OA and UA on induction of apoptosis in human hepatocellular carcinoma HuH7 cells and the related mechanisms were investigated. The results demonstrate that OA and UA could inhibit the growth of HuH7 cells with IC(50) values of 100 and 75 microM, respectively. Cell cycle analysis using flow cytometry indicated that the fraction of HuH7 cells in sub-G1 phase progressively increased with increasing concentrations of OA or UA from 20 to 80 microM. Treatment with OA and UA for 8 h induced a dramatic loss of the mitochondria membrane potential and interfered with the ratio of expression levels of pro- and antiapoptotic Bcl-2 family members in HuH7 cells. OA and UA-induced apoptosis involving the release of mitochondria cytochrome c into the cytosol and subsequently induced the activation of caspase-9 and caspase-3, followed by cleavage of poly (ADP-ribose) polymerase (PARP). Moreover, HuH7 cells treated with OA and UA suppressed the activity of NF-kappaB and modulated the mRNA expression of X-linked inhibitor of apoptotic protein (XIAP) as compared with untreated cells. These results demonstrate that OA and UA induce apoptosis in HuH7 cells through a mitochondria-mediated pathway and downregulation of XIAP.

TL;DR: In this article, a high-performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry was used to analyze the alteration of constituents in the infusion of oolong tea resulting from its manufacture.
Abstract: Oolong tea manufactured via a semifermentation process possesses a taste and color somewhere between green and black teas. Alteration of constituents, particularly phenolic compounds, in the infusion of oolong tea resulting from its manufacture, was analyzed by high-performance liquid chromatography coupled to electrospray ionization tandem mass spectrometry. The identified constituents contained 2 alkaloids, 11 flavan-3-ols, 8 organic acids and esters, 11 proanthocyanidin dimers, 3 theaflavins, and 22 flavonoid glycosides, including 6 novel acylated flavonol glycosides. The tentative structures of these 6 novel compounds were depicted according to their mass fragmentation patterns in MSn (n = 1−4). In comparison with caffeine as an internal standard, relative contents of the constituents in the infusions of fresh tea shoot and different oolong tea preparations were examined. Approximately, 30% catechins and 20% proanthocyanidins were oxidized during the manufacture of oolong tea from fresh tea shoots, an...
