Tissue remodeling under pathological conditions is stable morphological and functional rebuilding that correlates closely with the state of mucosa. This concept is used in many areas of medicine though hardly employed in dentistry. The paper presents histological and immunohystochemical data confirming tissue remodeling and the role of immunocells in periodontal disease. Tissue remodeling in chronic inflammatory periodontal lesions corresponds to the degree of the clinical manifestation, and consist at least of: i) alteration of gingival epithelial cells regeneration and differentiation due to changes in cell-mediated local adaptive immune response; ii) active accumulation of lymphocytes subpopulations and dendritic cells in the subepithelial compartment; iii) and progressive bone destruction associated with osteoimmunological interactions. The introduction of remodeling concept and further researches in this area with subsequent application in dental practice might advance treatment approaches to chronic periodontal disease.

Background: With a decline of 17β-estradiol (E2) at menopause, E2 has been implicated in the accompanied loss of skeletal muscle mass and strength. We aimed at characterizing transcriptomic responses of skeletal muscle to E2 in female mice, testing the hypothesis that genes and pathways related to contraction and maintenance of mass are differentially expressed in ovariectomized mice with and without E2 treatment.
Methods: Soleus and tibialis anterior (TA) muscles from C57BL/6 ovariectomized mice treated with placebo (OVX) or E2 (OVX + E2) for 60 days, or from skeletal muscle-specific ERα knockout (skmERαKO) mice and wild-type littermates (skmERαWT), were used for genome-wide expression profiling, quantitative real-time PCR and immunoblotting.

The presence of high levels of fluoride (F) in groundwater is a major issue worldwide. Although F is essential for healthy teeth and bones, excessive exposure can cause fluorosis or F toxicity. This condition primarily affects the hard tissues due to their high F retention capacity.

Inflammaging, a state of chronic low-grade inflammation associated with aging, has been linked to the development and progression of various disorders. Cellular senescence, a state of irreversible growth arrest, is another characteristic of aging that contributes to the pathogenesis of cardiovascular pathology. Senescent cells accumulate in tissues over time and secrete many inflammatory mediators, further exacerbating the inflammatory environment.

Pathological cardiac remodeling is a maladaptive response that leads to changes in the size, structure, and function of the heart. These changes occur due to an acute or chronic stress on the heart and involve a complex interplay of hemodynamic, neurohormonal and molecular factors. As a critical regulator of cell growth, protein synthesis and autophagy mechanistic target of rapamycin complex 1 (mTORC1) is an important mediator of pathological cardiac remodeling.

Pulsed-field ablation (PFA) offers notable advantages in atrial fibrillation (AF) ablation by selectively targeting cardiomyocytes via an irreversible electroporation mechanism, thereby minimizing damage to surrounding tissues. Although clinical studies demonstrate that PFA is both safe and effective, PFA-mediated hemolysis and potential acute kidney injury (AKI) development have been recently reported. This study comprehensively reviews the literature on PFA-associated hemolysis, analyzing the underlying mechanisms, risk factors, and preventive management strategies.
