TL;DR: The obtained results suggest that the as-synthesized luminescent nanorods could be potentially used in invisible security ink and high-contrast bioimaging applications.
Abstract: Herein we have established a strategy for the synthesis of highly luminescent and biocompatible europium-doped lanthanum orthophosphate (La0.85PO4Eu0.153+) nanorods. The structure and morphogenesis of these nanorods have been probed by XRD, SEM, and TEM/HRTEM techniques. The XRD result confirms that the as-synthesized nanorods form in a monazite phase with a monoclinic crystal structure. Furthermore, the surface morphology shows that the synthesized nanorods have an average diameter of ∼90 nm and length of ∼2 μm. The HRTEM images show clear lattice fringes that support the presence of better crystal quality and enhanced photoluminescence hypersensitive red emission at 610 nm (5D0–7F2) upon 394 nm wavelength excitation. Furthermore, time-resolved spectroscopy and an MTT assay of these luminescent nanorods demonstrate a photoluminescent decay time of milliseconds with nontoxic behavior. Hence, these obtained results suggest that the as-synthesized luminescent nanorods could be potentially used in invisible ...

TL;DR: In this paper, nine new fluorine containing 5-amino-1,3-disubstituted pyrazoles have been synthesized and characterized by spectral studies and the structures of the resulting 1H-pyrazolo[3,4-b]pyridines have been confirmed by ir, pmr and 19F nmr spectral studies.

TL;DR: The protection afforded by flaxseed oil may be attributed to the constituents of the oil, which include omega‐3 essential fatty acids and phytoestrogenic lignans, which appear to play an important role in free radical scavenging and singlet oxygen quenching.
Abstract: Flaxseed (linseed, Linum usitatissimum, Linaceae) is widely used for its edible oil in many parts of the world. The present study investigates the radioprotective and antioxidative potential of flaxseed oil (FO). Swiss albino mice were administered FO orally once daily for 15 consecutive days, then exposed to a single dose of 5 Gy of gamma radiation. Lipid peroxide, reduced glutathione and total protein were estimated in the liver. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), acid and alkaline phosphatase estimations in serum were also carried out. Radiation-induced increases in the levels of lipid peroxidation (LPO), AST, ALT and acid phosphatase were significantly ameliorated by flaxseed oil pretreatment, and radiation-induced depletion in the level of glutathione (GSH) and alkaline phosphatase activities was significantly inhibited by flaxseed oil administration. The lifespan was increased in the flaxseed oil treated irradiated mice in comparison with their respective control mice, with survival data showing an LD50/30 (lethal dose for 50% of animals after 30 days) of 7.1 and 10 Gy for control and FO treated irradiated mice, respectively, and produced a dose reduction factor for flaxseed oil (DRF) of 1.40. Radiation-induced deficits in body and organ weight were significantly reduced or prevented in flaxseed oil pretreated mice. The protection afforded by flaxseed oil may be attributed to the constituents of the oil, which include omega-3 essential fatty acids and phytoestrogenic lignans, which appear to play an important role in free radical scavenging and singlet oxygen quenching. The study does not rule out the possibility of a prophylactic potential of flaxseed oil against radiation-induced degenerative changes in liver. Copyright © 2007 John Wiley & Sons, Ltd.

TL;DR: The present data suggest that the Syzygium cummini extract has anti-tumor and anti-oxidative potential against chemical induced stomach carcinogenesis.
Abstract: Syzygium cummini extract (SCE) was used in the present study to explore anti-tumor promoting activity in a stomach carcinogenesis model in mice. For this purpose, Swiss albino mice were administered with 1 mg of benzo-a-pyrene (BaP) in 100μl sesame oil by oral gavage twice a week for 4 consecutive weeks. The animals were sacrificed 14 weeks after the last administration of BaP. Oral administration of the extract to pre-treated (i.e. SCE as 25mg/kg b. wt./ day before BaP application for 2 weeks), post-treated (i.e. SCE after BaP application for 8 weeks) and pre-post treated (i.e. SCE for 2 weeks before treatment of BaP followed by the concomitant treatment with SCE and BaP for 4 weeks during & 2 weeks after the last dose of BaP) groups provided a significant reduction in tumor incidence, tumor burden and cumulative number of gastric carcinomas along with a significant elevation of phase II detoxifying enzymes, and inhibition of lipid per oxidation in the stomach. Thus, the present data suggest that the Syzygium cummini extract has anti-tumor and anti-oxidative potential against chemical induced stomach carcinogenesis.
