The insecticidal and antifeedant activity of extracts derived from different plants of Aesculus hippocastanum L. (Hippocastanaceae), Viscum album L. (Loranthaceae), Sambucus nigra L. (Caprifoliaceae), Buxus sempervirens L. (Buxaceae), Diospyros kaki L. (Ebenaceae), Artemisia absinthum L. (Compositae), Alnus glutiosa Goertn. (Betulaceae), Origanum vulgare L., (Labiatae), Hypericum androsaemum L....

Heat treatment of persimmon peel (PP) increased the antioxidative activity of the 70% ethanolic extract (EE) and water extract (WE) from PP. EE and WE both prevented H2O2-induced DNA damage to human peripheral lymphocytes. The antioxidative and antigenotoxic activities of the PP extracts were significantly affected by heating.

Azide terminally functional poly(methyl methacrylate)s (Mn = 4000-6000, PDI = 1.21-1.28) have been prepared by living radical polymerization and successfully reacted with alkynes in a Huisgen cycloaddition (click) reaction in one pot using the same catalyst for both processes.

Efficient continuous-wave (cw) lasing of Cr(2+):ZnS and Cr(2+):ZnSe crystals in external hemispherical cavities and in a microchip configuration under Er-fiber-laser pumping at room temperature are reported. The key result is what is believed to be the first successful demonstration of cw Cr(2+):ZnS and Cr(2+):ZnSe microchip lasers with maximum output powers of 63 and 100 mW at 2320 and 2520 nm...

We report a procedure to detect mid-infrared single photons at 4.65 microm by means of a two-stage scheme based on sum-frequency generation, by using a periodically poled lithium niobate nonlinear crystal and a silicon avalanche photodiode. An experimental investigation shows that, in addition to a high timing resolution, this technique yields a detection sensitivity of 1.24 pW with 63 mW of ne...

This study quantifies sex differences in thermoregulation and water loss of a small (20-35 g) insectivorous heterothermic mammal, the hoary bat Lasiurus cinereus, during its spring migration. We measured body temperature, metabolic rate and evaporative water loss, and calculated wet thermal conductance, for bats exposed to air temperatures ranging from 0 to 40 degrees C for periods of 2-5 h. Pr...

Background & Aim: A gag reflex (GR) can be a problem to compliance and delivery of dental treatment. The aim of this study was to evaluate the use of Diospyros kaki L. fruit extract in controlling gag reflex during dental treatment. Experimental: Our study was a randomized double blind controlled trial with convenient sampling on 84 patients that is candidate for ra...

We developed and characterized expressed sequence tags (ESTs)-simple sequence repeats (SSRs) and targeted region amplified polymorphism (TRAP) markers to examine genetic relationships in the persimmon genus Diospyros gene pool. In total, we characterized 14 EST-SSR primer pairs and 36 TRAP primer combinations, which were amplified across 20 germplasms of 4 species in the genus Diospyros. We use...
