Glucuronidation constitutes a major mechanism in the deactivation and elimination of many xenobiotics [ 1, 21. As a general method to study glucuronidation of a range of substrates in intact cells, we have developed an h.p.1.c.-based method for measuring the incorporation of I4C into glucuronides, following the labelling of the UDP-glucuronic acid (UDPGA) pool of isolated liver cells by incubat...
Background and Objective: Adhesion bands comprise the most important unpleasant consequences of pelvic surgeries. Green tea (Camellia sinensis), due to its anti-oxidant and anti-inflammatory effects and prevention of production and accumulation of collagen seems to be beneficial in this event. Therefore, the present study was designed to elicit the effect of alcoholic extract of green tea on in...
An efficient method is proposed for obtaining tetrahydrobenzo[a]xanthene-11-ones and tetrahydro-[1,3]-dioxolo[4,5-b]xanthen-9-ones. The method is based on the use of p-sulfonic acid calix[n]arenes as catalysts under solvent-free conditions. The antiproliferative activity of fifty-nine xanthenones against six human cancer cells was studied. The capacity of all compounds to inhibit cancer cell gr...
Genetically modified (GM) rice KMD1, TT51-1, and KF6 are three of the most well known transgenic Bt rice lines in China. A rapid and sensitive molecular assay for risk assessment of GM rice is needed. Polymerase chain reaction (PCR), currently the most common method for detecting genetically modified organisms, requires temperature cycling and relatively complex procedures. Here we developed a ...
where the values of the forward (kd) and reverse (kp) rate constants may be different from those in the ground state because of differences in the properties of the 2-naphthol in these two states (for example, Ka 6= K ∗ a in part I). The objective of this experiment is to determine the deprotonation/protonation rate constants of 2-naphthol in its lowest excited singlet state in aqueous solution...
A room-temperature phosphorimetric (RTP) study of the inclusion process between 1- and 2-naphthol, beta-cyclodextrin (beta-CD) and 3-bromo-1-propanol as heavy atom pertuber has been performed. Experimental conditions were optimized for the formation of trimolecular complexes with lifetimes of 10.82 and 9.41 ms for 1- and 2-naphthol, respectively. A synchronous-derivative room-temperature phosph...
