Published: December 2004

After a decade of intense pharmacological and drug development activity by the pharmaceutical industry, compounds derived from two key strategies for reducing gastrointestinal effects of non-steroidal anti-inflammatory drugs (NSAIDs) have been subjected to rigorous clinical appraisal. Despite the undoubted therapeutic and commercial success of the selective cyclooxygenase (COX)-2 inhibitors, known as the coxibs, with second-generation compounds already approved and launched, some concerns over their full gastrointestinal profile still linger, while the cardiovascular safety of this class has become a key issue. Likewise, Phase II evaluation of compounds incorporating a nitric oxide (NO)-donating moiety into standard NSAIDs (the NO-NSAIDs or CINODs) has created recent controversy over the full clinical profile of these compounds. Other approaches such as NO-COX-2 inhibitors and dual COX-lipoxygenase inhibitors are already warranting interest. It might therefore be too early to predict the eventual winning strategy for safer anti-inflammatory drugs.

Pharmaceuticals, including non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (IBU) and naproxen (NPX), are widely used for medical purposes but have also become prevalent environmental contaminants. However, there is limited understanding of their effects on aquatic organisms, especially regarding multigenerational and mixture exposures. This study aimed to evaluate the toxicological impacts of ibuprofen and naproxen, individually and in combination, on three generations of Daphnia carinata, a freshwater organism.

Dasatinib-induced colitis in a patient with chronic myeloid leukaemia.

BMJ Case Rep

January 2025

Department of Digestive Health, Gold Coast University Hospital, Gold Coast, Australia, Gold Coast Hospital and Health Service, Southport, Queensland, Australia.

Dasatinib is a common treatment for chronic myeloid leukaemia with numerous side effects including gastrointestinal. We report a woman in her 50s who presented with haematochezia, weight loss and a positive faecal occult blood test. She was being treated for chronic myeloid leukaemia with dasatinib without the use of any concurrent medications, including non-steroidal anti-inflammatory drugs.

This research aims to design a novel selective and multifunctional adsorbent based on Al/Cu modified hemp fibres as a novel and multifunctional adsorbent for removing different classes of pollutants. The adsorbent, which was widely characterized, was shown to be more effective in removing anionic dyes compared to cationic ones. Among the tested dye, methyl orange was selected to understand how different parameters, such as temperature (20-80°C), contact time, pH (2-12), initial dye concentration (50-300 ppm), salinity and adsorbent dosage (1-10 g/L) affect the removal capacity.

Mast cell proteases and metastasis.

Pathol Res Pract

December 2024

Department of Translational Biomedicine and Neuroscience, University of Bari Medical School, Bari, Italy. Electronic address:

Mast cells exert multiple roles beyond their classical role in IgE-mediated allergic reactions. These cells secrete pro-inflammatory and anti-inflammatory agents and change from protective immune cells to pro-inflammatory cells, capable of influencing the progression of different pathological conditions, including tumors, in which they exert anti-tumorigenic and pro-tumorigenic roles. In this context, this article analyzes the potential role played by mast cell-derived proteases in tumor progression and more specifically in driving metastatic process and the potential therapeutic approaches that inhibiting the activation of these cells could help faith cancer spreading.
