For instance, dulaglutide showed promise in the AWARD-7 trial, maintaining glycemic control and potentially preserving renal function
In the initiation stage of ferroptosis, long-chain fatty acid CoA ligase 4 (ACSL4) catalyzes the binding of PUFAs (such as arachidonic acid AA and adrenic acid AdA) to CoA via thioester bonds to form activated fatty acyl-CoA derivatives ( + ) to catalytically active Fe + through the NADPH-dependent electron transport system, continuously driving the Fenton reaction and accelerating the generation of hydroxyl radicals (OH), thus forming a self-reinforcing cycle of lipid peroxidation and ROS production ( 2.3 Dual defense network of the antioxidant system Cells have constructed a dynamic protective system against ferroptosis, which consists of an enzymatic defense system with the glutathione (GSH)-glutathione peroxidase 4 (GPX4) axis as the core and a multi-layered antioxidant network independent of GPX4
Nuts can be frozen for up to a year without losing their flavor or crunch
Important safety considerations include risk of thyroid C-cell tumors (contraindicated in MEN2 or personal/family history of medullary thyroid carcinoma), pancreatitis, gallbladder disease, hypoglycemia when used with insulin or secretagogues, and potential worsening of diabetic retinopathy in some patients
