Vascular Calcification: Mechanisms, Models, and Therapies

iNew Medicine, EarlyView.
ABSTRACT Vascular calcification represents an active multifactorial process that mirrors several key features of skeletal bone mineralization. Clinically, it is characterized by diminished arterial compliance and increased arterial wall stiffness, both of which serve as independent predictors of significant adverse cardiovascular events.

Circumscribed Morphea Successfully Treated With Excimer Laser: Analysis of Histopathological Changes

The Journal of Dermatology, EarlyView.
ABSTRACT Localized scleroderma (LSc) is an autoimmune condition characterized by localized cutaneous sclerosis, sometimes extending into deeper tissues. Phototherapy, including excimer laser therapy (ELT), is considered an effective and minimally invasive treatment option for patients without extracutaneous involvement.
