Rapid improvement of renal microcirculatory homeostasis by liraglutide following diabetes induction

Diabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Renal microvascular dysfunction is a central driver of diabetic kidney disease, yet the potential for rapid therapeutic reversal remains obscure. We investigated the effect of short‐term liraglutide on early changes in the renal microcirculation post‐induction of diabetes.

Establishment of an MRI‐Based Diagnostic Approach to Identify Critical Pulpal Inflammation Zones in a Rat Caries‐Derived Pulpitis Model

International Endodontic Journal, EarlyView.
ABSTRACT Aim To establish a magnetic resonance imaging (MRI)‐based diagnostic approach for identifying ‘critical pulpal inflammation’ zones in a rat model of caries‐derived pulpitis. Methodology Caries‐derived pulpitis was induced in the molars of Sprague–Dawley rats using the caries‐derived pulpitis model.

Soft‐Tissue Integration of Dental Implants: Formation, Maintenance, and Relevance for Peri‐Implant Health

Journal of Periodontal Research, EarlyView.
Sixty years after the introduction of dental implants, it is clear that soft‐tissue integration is as essential as osseointegration. This review outlines how peri‐implant soft tissues develop, protect, and sometimes fail, revealing key knowledge gaps and new opportunities to improve long‐term implant stability.
