Recent studies using small bowel endoscopy revealed that non-steroidal anti-inflammatory drugs including low-dose aspirin, can often induce small bowel injury. Non-steroidal anti-inflammatory drugs-induced small bowel mucosal injury involves various factors such as enterobacteria, cytokines, and bile. Experimental studies demonstrate that both mitochondrial disorders and inhibition of cyclooxyg...

About 5% of all National Health Service prescriptions in Britain and a quarter of reports of suspected adverse reactions are accounted for by non-steroidal anti-inflammatory drugs. Their prescription was investigated in two computerised group practices serving 11850 patients. Altogether 198 patients receiving repeat prescriptions of non-steroidal anti-inflammatory drugs were identified and rele...

Steroidal compounds exhibit particular physiological activities. In this paper, some steroidal thiosemicarbazones platinum (Pt(II)) complexes were synthesized by the condensation of steroidal ketones with thiosemicarbazide using estrone, chenodeoxycholic acid, and 7-deoxycholic acid as starting materials and complexation of steroidal thiosesemicarbazones with Pt(II). The complexes were characte...

We have investigated the antibacterial activity of some new steroidal thiosemicarbazones and their Pd(II) metal complexes were prepared by the reaction of the thiosemicarbazones with [Pd(DMSO)(2)Cl(2)]. The steroidal thiosemicarbazones were prepared by the reaction of thiosemicarbazides with a steroidal ketone. The structures of these compounds were elucidated by IR, (1)H-NMR, (13)C-NMR, FAB ma...

OBJECTIVE To estimate the risk of acute hepatotoxicity associated with nimesulide compared with other non-steroidal anti-inflammatory drugs. DESIGN Retrospective cohort and nested case-control study. SETTING Umbria region, Italy. PARTICIPANTS 400 000 current, recent, and past users (almost 2 million prescriptions) of non-steroidal anti-inflammatory drugs between 1 January 1997 and 31 Dece...

Aromatase inhibition is an effective treatment strategy for breast cancer. Currently, several in silico methods have been developed for the prediction of aromatase inhibitors (AIs) using artificial neural network (ANN) or support vector machine (SVM). In spite of this, there are ample opportunities for further improvements by developing a simple and interpretable quantitative structure-activity...

Recent structure-antileukemic activity studies showed that the steroidal part of complex molecules containing DNA alkylators does not play only the role of the "biological carrier". New such compounds designed to possess an allylic 7-ketone showed enhanced antileukemic potency compared with derivatives with a simple steroidal skeleton. In order to investigate whether the enhancement of the anti...

A simple and practical method for synthesis of the D-ring modified steroidal dienamides (4a-k) from the steroidal α,α-dicyanoalkene 3 and aldehydes via vinylogous aldol reaction was first reported. By using NaOAc as a base, the desired products were obtained in moderate to good yields in ethanol under mild conditions. All the synthesized steroidal dienamides are new and are currently being eval...

purpose: to report a case of severe macular edema following the taking of fingolimod in multiple sclerosis. case report: a 34-year-old woman with a long history of relapsing-remitting multiple sclerosis presented complaining of blurred vision in the left eye that started 1 week before the presentation. she had been taking fingolimod for 4 months. she was not diabetic and had no history of uveit...
