Comparative analysis of melatonin’s protective role against flattening filter and flattening filter-free X-ray induced nephropathy: focus on apoptosis and SIRT1 modulation

BMC Nephrology
Background Radiation-induced nephropathy is a major concern, particularly for patients undergoing radiotherapy. This study investigates melatonin’s (MEL) protective effects against kidney damage induced by Flattening Filter (low dose rate-LDR) and ...

On generalized symmetric powers and a generalization of Kolmogorov-Gelfand-Buchstaber-Rees theory

, 2007
The classical Kolmogorov-Gelfand theorem gives an embedding of a (compact Hausdorff) topological space X into the linear space of all linear functionals C(X)^* on the algebra of continuous functions C(X).

Ultrastructural and immunohistochemical evaluation of hyperplastic soft tissues surrounding dental implants in fibular jaws

Scientific Reports
In reconstructive surgery, complications post-fibula free flap (FFF) reconstruction, notably peri-implant hyperplasia, are significant yet understudied. This study analyzed peri-implant hyperplastic tissue surrounding FFF, alongside peri-implantitis and ...
