Elevated serum phosphate has emerged as a major risk factor for vascular calcification. The sodium-dependent phosphate cotransporter, PiT-1, was previously shown to be required for phosphate-induced osteogenic differentiation and calcification of cultured human vascular smooth muscle cells (VSMCs), but its

The effects of canagliflozin, a sodium glucose co-transporter 2 inhibitor, on blood pressure (BP) and osmotic diuresis- and intravascular volume reduction-related adverse events (AEs) were evaluated using pooled data from four placebo-controlled, phase 3 studies in patients with type 2

Remote ischaemic preconditioning (RIPC), using brief cycles of limb ischaemia/reperfusion, is a non-invasive, low-cost intervention that may reduce perioperative myocardial injury (PMI) in patients undergoing cardiac surgery. We investigated whether RIPC can also improve short-term clinical outcomes. One hundred and
