Nanoparticles Induced Biomimetic Remineralization of Acid-Etched Dentin.

Statement Of The Problem: Dentin bonding with etch-and-rinse adhesives involves demineralizing the 5-8µm of the surface dentin to create micro space for resin infiltration. The presence of continuous fluid movement in dentin tubules and positive pulpal pressure prevents complete water replacement by resin monomers. This results in areas of demineralized dentin, which contain collagen fibers without resin infiltration.

Breaking the storm: ruxolitinib as a lifeline in refractory hemophagocytic lymphohistiocytosis with macrophage activation syndrome.

This case report presents the management of a 25-year-old woman with refractory hemophagocytic lymphohistiocytosis (HLH) secondary to adult-onset Still's disease. Despite initial treatment with corticosteroids and biologic therapies, including anakinra and tocilizumab, her condition continued to deteriorate, necessitating intensive care unit admission. Following multidisciplinary consultation, ruxolitinib therapy, a Janus kinase (JAK) inhibitor targeting hyperinflammation, was initiated.

Computational and Experimental Insights into Pharmacological Potential: Synthesis, In Vitro Evaluation, and Molecular Docking Analysis of Bioactive Urea and Thiourea Derivatives.

This study delves into the synthesis, in vitro assessment, and molecular docking analysis of bioactive urea and thiourea derivatives, which have gained attention in pharma chemistry due to their versatile chemical reactivity and potential therapeutic applications.

Necrolytic migratory erythema: a fortuitous diagnosis.

A woman in her late 60s presented with widespread, itchy, dark lesions over her trunk and legs for 1 month. Initially, she was managed as nutritional dermatitis and experienced partial improvement. However, her condition worsened over 2 months, characterised by aggravated skin lesions, new-onset diabetes and a 12 kg weight loss.
