Aromatic fumaronitrile core-based donor-linker-acceptor-linker-donor (D-pi-A-pi-D) compounds: synthesis and photophysical properties.

A new class of aromatic fumaronitrile core-based compounds with different donors and linkers has been synthesized and well characterized. Compounds 1 and 2 have indole and 2-phenylindole groups as electron donors, respectively. Compounds 3 and 4 have a diphenylamino group as the electron donor, and compound 5 has a 3,6-di-tert-butylcarbazole group as an electron donor.

Carbazole donor-carbazole linker-based compounds: preparation, photophysical properties, and formation of fluorescent nanoparticles.

A new class of highly soluble and stable compounds (1-4) has been synthesized and characterized. Compounds 1, 2, and 3 have 3,6-disubstituted carbazole as electron-donor-linked through the 2,7-positions of N-substituted carbazole with variably substituted phenyl acetylenes as electron acceptors. Compound 4 has two identical donors linked through the 2,7-position of N-substituted carbazole.

The perception of elder sexual abuse in the courtroom.

This study explored mock juror perceptions of elder sexual mistreatment (ESM). In Experiment 1, 118 participants read a fictional criminal trial summary of an ESM case in which a 76-year-old woman was allegedly abused by either her son or a neighbor. In Experiment 2 (n = 360), the ESM occurred in either a nursing home or the elder's home and the alleged perpetrator was either her son or a nursing home worker.

The impact of juror characteristics and victim health status on the perception of elder physical abuse.

An experiment investigated mock juror perceptions of elder abuse using a community sample from Lexington, Kentucky. Two-hundred six men and women ranging in age from 18 to 88 read a fictional criminal trial summary of a case of elder physical abuse (EPA) in which the accuser was described as healthy, frail, or confused. In addition, the influence of participant age, participant gender, and attitude toward the elderly on juror perceptions of EPA was also investigated.

Colchitaxel, a coupled compound made from microtubule inhibitors colchicine and paclitaxel.

Background: Tumor promoters enhance tumor yield in experimental animals without directly affecting the DNA of the cell. Promoters may play a role in the development of cancer, as humans are exposed to them in the environment. In work based on computer-assisted microscopy and sophisticated classification methods, we showed that cells could be classified by reference to a database of known normal and cancerous cell phenotypes.

The effect of gender in the perception of elder physical abuse in court.

Two experiments investigated mock jurors' perceptions of elder abuse (EA) in a physical assault case. In Experiment 1, participants read a fictional criminal trial summary of a physical assault case in which the alleged victim was 66, 76, or 86 years old. In Experiment 2, the age of the alleged victim was 76 years old, but the gender of the alleged victim and the gender of the defendant were crossed.

The effects of pH and rat intestinal contents on the liberation of ellagic acid from purified and crude ellagitannins.

This study was undertaken to measure the liberation in vitro of ellagic acid [2], a naturally occurring inhibitor of carcinogenesis, from precursor ellagitannins under conditions found in the gut tract. Enzymes, namely beta-glucosidase, esterases, and alpha-amylase, were incubated with raspberry extract. In addition, raspberry extract and casuarictin [1] were treated at different pH's and with the contents of small intestine and cecum from rats fed AIN-76A diet.
