One Heartbeat Away from a Prediction Model for Cardiovascular Diseases in Patients with Chronic Kidney Disease: A Systematic Review.

Introduction: Patients with chronic kidney disease (CKD) have a high risk of cardiovascular disease (CVD). Prediction models, combining clinical and laboratory characteristics, are commonly used to estimate an individual's CVD risk. However, these models are not specifically developed for patients with CKD and may therefore be less accurate.

Sustained contractile force regulated by rho-kinase and protein kinase C in sheep carotid arterial smooth muscle.

The time course of smooth muscle contraction can be divided into two phases, the initial phase is associated with force development, whereas the sustained phase is associated with force maintenance. Cumulative evidence suggests that the two phases are regulated by different signaling pathways and that ρ-kinase (ROCK) and protein kinase C (PKC) play an important role in regulating isometric force in sustained contractions. Since the maintenance of sustained force is critical to the function of vascular smooth muscle, unraveling the complex mechanism of force maintenance is crucial for understanding the cell biology of the muscle.
