Spinal actions of lipoxin A4 and 17(R)-resolvin D1 attenuate inflammation-induced mechanical hypersensitivity and spinal TNF release.

Lipoxins and resolvins have anti-inflammatory and pro-resolving actions and accumulating evidence indicates that these lipid mediators also attenuate pain-like behavior in a number of experimental models of inflammation and tissue injury-induced pain. The present study was undertaken to assess if spinal administration of lipoxin A4 (LXA4) or 17 (R)-resolvin D1 (17(R)-RvD1) attenuates mechanical hypersensitivity in the carrageenan model of peripheral inflammation in the rat. Given the emerging role of spinal cytokines in the generation and maintenance of inflammatory pain we measured cytokine levels in the cerebrospinal fluid (CSF) after LXA4 or 17(R)-RvD1 administration, and the ability of these lipid metabolites to prevent stimuli-induced release of cytokines from cultured primary spinal astrocytes.

Pentoxifylline and melatonin in combination with pioglitazone ameliorate experimental non-alcoholic fatty liver disease.

Insulin resistance, oxidative stress and cytokine imbalance are key pathophysiological mechanisms in non-alcoholic fatty liver disease (NAFLD). This study aimed at evaluating the effect of treatment with the insulin sensitizer, pioglitazone, the tumor necrosis factor-α inhibitor, pentoxifylline, and the antioxidant, melatonin and their combinations in rats with NAFLD. Rats were fed a high-fat diet (HFD) for eight weeks to induce NAFLD.

Anti-angiogenic effect of resveratrol or curcumin in Ehrlich ascites carcinoma-bearing mice.

The phytochemicals, resveratrol or curcumin, have been shown to possess many pharmacological activities including anti-inflammatory, anti-oxidant, anti-microbial and anti-cancer effects. However, the underlying mechanism for their anti-tumor activity is yet to be evaluated. The present study was carried out to investigate the anti-angiogenic effect of resveratrol or curcumin when used alone or in combination with carboplatin in Ehrlich ascites carcinoma (EAC)-bearing mice.

Cisplatin-induced cardiotoxicity: Mechanisms and cardioprotective strategies.

Increased oxidative stress and apoptosis have been implicated in the cardiotoxicity that limits the clinical use of cisplatin as an anti-tumoral drug. Our study was conducted to evaluate the protective potential of acetyl-l-carnitine, DL-α-lipoic acid and silymarin against cisplatin-induced myocardial injury. Eighty male albino rats were divided into eight groups.

Student perspectives on pharmacy curriculum and instruction in Egyptian schools.

Objectives: To determine student attitudes and opinions towards pharmacy education in Egyptian universities to provide information for designing delivery of a revised pharmacy curriculum.

Methods: Students were recruited from the pharmacy faculties at a government-sponsored university and a privately funded university. Data were gathered using a structured questionnaire and statistically analyzed.
