piroxicam has two different crystalline forms (known as needle and cubic forms), that they are different in physicochemical properties such as biological solubility. in the current research, using taguchi experimental design approach the influences of five operating variables on formation of the piroxicam polymorph shapes in recrystallization were studied. the variables include type of solvent,...

BACKGROUND AND PURPOSE Aquaporin-4(AQP4) is an abundant water channel protein in brain that regulates water transport to maintain homeostasis. Cerebral edema resulting from AQP4 over expression is considered to be one of the major determinants for progressive neuronal insult during cerebral ischemia. Although, both upregulation and downregulation of AQP4 expression is associated with brain path...

Background: Chemotherapy is expected to remain an important part of invasive urothelial carcinoma (UC) treatment. Strategies to enhance chemotherapy efficacy are needed. Objective: To determine the chemotherapy-enhancing effects of a nonselective cyclooxygenase (COX) inhibitor on vinblastine in a naturally-occurring canine model of invasive UC. Methods: With IACUC approval, privately-owned dogs...

Prostaglandin E2 (PGE2) has served as a surrogate end point biomarker in colorectal tumor progression. Colonic mucosa PGE2 levels of patients with colorectal adenomas or carcinomas have been shown to be higher than in control subjects. Our dose-finding study on piroxicam, a nonsteroidal anti-inflammatory drug with chemopreventive effects in preclinical colon carcinoma models, suggested that 7.5...

Experimental charge density distribution studies of two polymorphic forms of piroxicam, β-piroxicam (1) and piroxicam monohydrate (2), were carried out via high-resolution single crystal X-ray diffraction experiments and multipole refinement. The asymmetric unit of (2) consists of two discrete piroxicam molecules, (2a) and (2b), and two water molecules. Geometry differs between (1) and (2) due ...

The purpose of our study was to examine whether cyclooxygenase and lipoxygenase inhibitors ameliorate delayed neuronal death in the hippocampal CA1 sector in Mongolian gerbils after 5 minutes of forebrain ischemia. Gerbils were injected intraperitoneally with cyclooxygenase inhibitors piroxicam and flurbiprofen or with lipoxygenase inhibitors AA-861 and BW-755C. Seven days after ischemic insult...

abstract objective: to investigate the effect of an anti-inflammatory drug (piroxicam) on the development of fatty streak in rabbits. methods: male rabbits were fed with four types of regimen: a) normal rabbit chow, b) 1% cholesterol diet c) cholesterol diet plus piroxicam, d) normal rabbit chow plus piroxicam. after 12 weeks, the animals were sacrificed and the aorta, as well as the right and ...
