One substance is called retinol-binding protein 4, which has been tied to an increased risk of coronary heart disease.
Also, urinary levels of renal injury markers such as the cortical tubular enzyme and proteins including NAG, retinol-binding protein, and [beta]2 - microglobulin were shown to be increased early after ESWL and reduced to normal within the proceeding days.11,15 In another study, levels of homocysteine, which is an indicator of oxidative stress, were shown to be increased following ESWL, and remain elevated even after three months when compared to baseline.16 Previous studies have also shown that antioxidant treatments can reduce OS caused by ESWL, and have favorable effects on kidney functions.11,12 Similar to all these reports, the present study has shown that ESWL treatment causes a transient augmentation of OS.
One such substance is called retinol-binding protein 4 (RBP4) that was found in a 16-year study of nurses to increase the risk of developing coronary heart disease.
Research has found that this type of fat also secretes retinol-binding protein 4 (RBP4), which has been found to increase insulin resistance.
Nutritional states were evaluated by the measurements of body weight, body composition, and muscle strength, and the nutritional hematological examination results (retinol-binding protein (RBP), prealbumin (PA), transferrin (Tf), and hemoglobin (Hb) in serum), and inflammation biomarkers such as carboxyhemoglobin (COHb), High sensitivity C-reactive protein (Hs-CRP), Tumor Necrosis Factor-alpha (TNF-[alpha]), Interleukin 6 (IL-6), and Serum Amyloid A (SAA) were measured.
Retinol-binding protein 4 (RBP4) is a newly discovered adipokine secreted by adipocytes and hepatocytes, and it is a specific transport protein for serum retinol [2].

Also of interest is that retinol-binding protein 4 was not associated with diabetes, which is in striking contrast to previous studies (4).
It serves as a transport protein for thyroxine and as a carrier for retinol-binding protein (RBP) [15].
It is noteworthy that the guanine nucleotide-binding protein (G protein) alpha-transducing activity polypeptide 2 (GNAT2) and retinol-binding protein 3 (RBP3) were jointly and significantly enriched in GO terms of sensory perception, cognition, and signaling by GPCR pathway.
