RESUMEN

Dyslipidemia is associated with an increased risk of cardiovascular events. Effect of ginger supplementation on lipid profile in humans remains controversial particularly in diabetic patients. A systematic search was performed covering PubMed, Medline, and Scopus, Web of Science (ISI), and Google scholar from January 2010 to January 2022. Inclusion criteria were randomized controlled clinical trials (RCT) study design, at least one of lipid profile components triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL-C), and high-density lipoprotein (HDL-C) measured before and after ginger consumption. For quantitative data synthesis, a random-effects model was applied. Pooled data showed that ginger intake reduced TC (SMD -0.44; 95% CI: -0.86, -0.02; p = 0.025) and TG (SMD -0.61; 95% CI: -1.14, -0.08; p = 0.024) levels significantly, but it has no significant effect on improving HDL-C (SMD 0.40; 95% CI: -0.01, 0.80; p = 0.057) and LDL-C (SMD -0.34; 95% CI: -0.81, 0.13; p = 0.153). Ginger supplementation decreased TG in obese and diabetic subjects more efficiently. In terms of ginger dose, the result of meta-regression found to be significant only for TC, so that increasing daily doses of ginger reduces TC levels by (ß: -0.67; 95% CI: -1.28, -0.07; p = 0.028). Therefore, ginger could be considered as an effective lipid lowering nutraceuticals.

RESUMEN

One of the primary indicators of plaque vulnerability is the lipid composition of atherosclerotic plaques. Therefore, the medical industry requires a method to evaluate necrotic nuclei in atherosclerosis imaging with sensitivity. In this regard, photoacoustic imaging is a plaque detection method that provides chemical information on lipids and cholesterol thickness in the arterial walls of the patient. This aspect aims to increase the low-frequency axial resolution by developing a new photoacoustic-based system. A photoacoustic system has been developed to detect the cholesterol thickness of the blood vessels to observe the progression of plaque in the heart's blood vessels. The application of the coherent photoacoustic discontinuous correlation tomography technique, which is based on a novel signal processing, significantly increased the cholesterol oleate's sensitivity to plaque necrosis. By enhancing the quality of thickness detection, the system for measuring the thickness of cholesterol in blood vessels has been reduced to approximately 23 microns. The results show that the phase spectrum peaked at 100 Hz at 58.66 degrees, and at 400 Hz, the phase spectrum was 46.37 degrees. The minimum amplitude is 1.95 at 100 Hz and 17.67 at 400 Hz. In conclusion, it can be stated that photoacoustic imaging as a method based on new technologies is of great importance in medical research, which is based on the use of nonionizing radiation to perform diagnostic processes and measure different types of body tissues.
