Abstract:
Shrunken pore syndrome (SPS) is a condition in which the estimated glomerular filtration rate (eGFR) based on serum/plasma cystatin C concentration is significantly lower than the eGFR based on creatinine. According to the literatures, the diagnosis of SPS could be defined when the eGFRcystatin C is <70% of eGFRcreatinine. Although the incidence of SPS varies in different patient populations and healthy seniors, it has been demonstrated that patients with SPS have poor prognosis. The present review has summarized its diagnosis, epidemiology, prognosis and possible pathophysiology basis. Moreover, we discuss the prevention and treatment of SPS in clinical practice as future challenges.

Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct...
