PURPOSE The release of drug from a polymeric matrix is complicated. It often involves drug diffusion, interface movement and various interactions. It also shows a dependence on the length of polymer rod. With Lc as the 'critical length', three different phases can be distinguished from the kinetic process. Prior to reaching Lc, the interface movement plays(More)
The effect of doping by boron on optical properties of multilayers containing Si-NCs were studied by means of photoluminescence (PL), time-resolved PL, photoluminescence excitation (PLE), transmission and reflection measurements. It was found that PL decay is strongly non-single exponential and can be described by means of Laplace transform of log-normal(More)
This study was conducted to explore the effects of interferon tau (IFNT) on the intestinal microbiota and expression of interleukin 17 (IL-17) in the intestine of mice. IFNT supplementation increased microbial diversity in the jejunum and ileum but decreased microbial diversity in the feces. IFNT supplementation influenced the composition of the intestinal(More)
With increasing interest in adopting phosphorus (P)-based manure application, a good knowledge of manure form-specific agronomic performance is needed to assure crop productivity and to safeguard the environment. We evaluated the effects of three forms of swine manure (liquid, LM; solid, SM; and liquid manure compost, MC), each applied at 100 kg P ha−1 in(More)
Ursolic acid, oleanolic acid, glycyrrhetinic acid, and betulinic acid, the representatives of pentacyclic triterpenes, were modified by introducing 2-methylene-3-oxo group as exocyclic α,β-unsaturated ketone moiety in ring A. The anti-bacterial and anti-tumor activities of these derivatives were assayed by comparing with the parent compounds. Results(More)
