Anticancer agents, such as cisplatin, stimulate nausea, vomiting, and behaviors indicative of malaise. Rats and mice do not possess a vomiting response, and, therefore, in these species, the ingestion of kaolin clay (a pica response) has been used as an index of malaise. In the rat, cisplatin-induced kaolin intake is inhibited by antiemetic treatments. In addition, cisplatin activates vagal aff...

Synthesis of indole derivatives was investigated and compared to the reaction of phenylhydrazine and ketones in the presence of the heterogeneous catalysts like kaolinite, montmorillonite K10 and Fe3O4 MNPs in ethanol under reflux conditions. After comparing the HPLC chromatogram of products it was compared and found that kaolin and montmorillonite K10 are better and more efficient candidate th...

We tested effects of kaolin particle film on oviposition, larval mining, and infestation of cotton by pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae), in the laboratory, greenhouse, and field. In laboratory choice tests, females laid seven times more eggs on untreated bolls than on bolls treated with kaolin. When neonates were put on bolls in the laboratory, each b...

Nanocomposites of aluminosilicate minerals, kaolins (kaolinite and halloysite) with natural different morphologies assembling with palladium (Pd) nanoparticles have been successfully synthesized through strong electrostatic adsorption and chemical bonding after surface modification with 3-aminopropyl triethoxysilane (APTES). Meanwhile, the influence of different morphologies supports on catalyt...

nano sio2/hyperbranched polyglycerol (hpg)/so3h catalyst was readily prepared for first time from inexpensive starting materials in aqueous media which catalyzed the synthesis of benzoic acid. ftir spectra, x-ray diffraction (xrd) and transmission electron micrographs (tem) was employed to characterize the properties of the synthesized nano sio2/hpg/so3h. high catalytic activity and ease of rec...

Structures and electronic properties of porphyrins with various Donor (D)-Acceptor (A) functionalization adsorbed on TiO2 (anatase) nanoparticles are studied using DFT calculations. Adsorption of porphyrin leads to a substantial loss of planarity (puckering) for the porphyrin rings due to the stabilization of the system by the interaction of the lone-pair of electrons of the N-atoms of porphyri...

the kaolinitic clays have been exploited for more than a hundred years, in the western part of the charentes basin, france, and belong to a paleo-deltaic network. the recent deposits are relatively richer in alumina in comparison with the older ones. the genesis of the kaolin deposits of the charentes basin follows simple geological rules, but their detailed geometry has a great complexity, rei...

Generation of active Factor XII (FXIIa) triggers blood clotting on artificial surfaces and may also enhance intravascular thrombosis. We developed a patterned kaolin (0 to 0.3 pg/μm(2))/type 1 collagen fibril surface for controlled microfluidic clotting assays. Perfusion of whole blood (treated only with a low level of 4 μg/mL of the XIIa inhibitor, corn trypsin inhibitor) drove platelet deposi...

In the present paper, a novel superabsorbent hydrogel composite based on carrageenan have been prepared via graft copolymerization of acrylic acid (AA) in the presence of kaolin powder using methylenebisacrylamide (MBA) as a crosslinking agent and ammonium persulfate (APS) as an initiator. The certain variables of the graft copolymerization (i.e. the monomer, the initiator and the crosslinker c...
