BACKGROUND Protease inhibitors such as ritonavir can cause nausea and vomiting which is the most common reason for discontinuation. Rats react to nauseous and emetic stimuli by increasing their oral intake of non-nutritive substances like kaolin, known as pica behavior. In this study, we evaluated the effects of methylnaltrexone, a peripherally acting mu-opioid receptor antagonist that does not...
تیتانیم دی اکسید (tio2) در زمین? تخریب آلاینده های موجود در آب به عنوان یک فوتوکاتالیست موثر بسیار مورد توجه است. در سالهای اخیر تثبیت فوتوکاتالیستها بر روی کانیهای مختلف برای بهبود عملکرد آنها گزارش شده است. در کار حاضر کامپوزیتهای دو جزئی با افزایش tio2 به کائولن و سه جزئی با افزایش tio2 و تنگستوفسفریک اسید (tpa) به کائولن تهیه شدند. کامپوزیتهای tio2-kaolin وtpa-tio2-kaolinبا مقادیر متفاوتی ا...
Research on the effect of cellulose and kaolin addition to alginate-cellulose-kaolin composites' characteristics as a slow-release agent urea fertilizer has been done. The technique used in preparation is an extrusion using 2% CaCl2 solution cross-linker. compositions were varied determine their such diameter, color, swelling ratio, entrapment efficiency, release urea. results showed that diame...
A series of quinazolines were synthesized from 2-aminobenzophenones and benzylic amines in good to excellent yields by employing a new heterogeneous catalyst based on the copper oxide nanoparticles supported on kaolin.
cisplatin is an effective chemotherapeutics against a wide range of cancers. however, it causes significant nausea and vomiting which limit its usefulness. in the present study, the effects of methanolic root extract of pluchea lanceolata (dc.) c. b. clarke , asteraceae ( mpl ) was investigated against cisplatin-induced nausea using a rat pica model. in rat pica model, rats react to cisplatin (...
Kaolinite clay found its application in medicine, in toothpaste, in cosmetic and as a food additive. Recently, a specially formulated spray is used in fruit and vegetable production to repel the insects and prevent sunburn. Kaolin-SO3H nanoparticles were prepared via reaction of kaolin and chlorosulfonic acid and characterized by FT-IR, XRD, FESEM, TEM, XRF, EDS, BET and TGA. 2-Substituted benz...
Highly sensitive graphene-based gas sensors can be made using large-area single layer graphene, but the cost of large-area pure graphene is high, making the simpler reduced graphene oxide (rGO) an attractive alternative. To use rGO for gas sensing, however, require a high active surface area and slightly different approach is needed. Here, we report on a simple method to produce kaolin-graphene...
These experiments examined the responses of articular blood vessels in the rabbit knee to induction of acute joint inflammation by intraarticular injection of 4% kaolin suspension. This produced an inflammatory response, which became evident about four hours after injection. Electrical stimulation of the nerve supply to the knee joint before induction of inflammation produced a biphasic respons...
Influence of kaolin and coal fly ash addition on biomass ash deposition in an entrained flow reactor
• Quantitatively studied K-Capture by kaolin/coal fly ash at dust-firing conditions. K-capture reaction biomass combustion and K-salt feeding conditions was compared. Deposit probe inserted into reactor lively monitored deposit formation. Deposition propensity quantitatively with without additive addition. The deposition behavior when firing different (pulverized wheat straw, wood, bark, leaves...
Preparation, Characterization, and Antimicrobial Activity of Chitosan/Kaolin Clay Biocomposite Films
Front Cover: In article 2300008 by Dhruba J. Haloi and co-workers, chitosan/kaolin clay biocomposite films are prepared mixing an aqueous acidic solution of chitosan with various amounts kaolin followed casting them in a petri dish. These exhibit better mechanical thermal properties good water absorption capacity. significant inhibition for the growth gram-negative bacteria.
