Carvacrol is a phenolic monoterpenoid compound that has antibacterial, antifungal, anti-cancer, and anti-inflammatory effects. Lipopolysaccharide (LPS) is derived from the outer cell wall of gram-negative bacteria and is responsible for acute kidney injury. In this research, the protective effect of carvacrol on lipopolysaccharide-induced acute kidney injury was studied. For this purpose, 40 male Wistar rats (200-250 g) were used. Animals were randomly divided into 5 equal groups: 1) control, 2) LPS group, 3) LPS+carvacrol (25 mg kg-1), 4) LPS+carvacrol (50 mg kg-1) and 5) LPS+carvacrol (100 mg kg-1). To induce acute renal injury, daily 1 mg kg-1 LPS for 2 weeks was injected intraperitoneally. Carvacrol was administered intraperitoneally daily for 30 minutes before LPS injection. LPS-induced kidney injury was evaluated by blood urea nitrogen (BUN), serum creatinine, and nitric oxide levels in kidney tissue by spectrophotometric methods. The level of the interleukin 1 beta was detected by ELISA in the kidney. Our results showed that LPS injection increased BUN, creatinine, nitric oxide, and IL-1β levels (P <0.001). Pretreatment with carvacrol reduced BUN at 25 mg kg-1 (P <0.001), 50 mg kg-1 (P <0.01), and 100 mg kg-1 (P <0.001) doses, nitric oxide at 25 mg kg-1 (P <0.05), 50 mg kg-1(P <0.01) and 100 mg kg-1(P <0.001) doses, and IL-1β levels (P <0.001) at all doses significantly but did not affect serum creatinine. These results indicate that carvacrol has an anti-inflammatory effect and protects kidneys against LPS by reducing pro-inflammatory mediators such as IL-1β and nitric oxide. Manuscript profile

Glucose tolerance test is advised to detection of pre-diabetics and mild diabetics in the medical practice. Several mathematical models such as glucose model, were proposed for mimicking the blood glucose-insulin interaction. To predict accurate insulin requirement for each glucose concentration, we need to solve optimal control problems. In this model, constraints are linear and nonlinear forms of cost function. Although ordinary methods can be used in glucose model, but non-negative natures of medical variables made them difficult to use. To finding a new approximate solution of glucose model, parameterization method with non-negative coefficients in polynomial was used. In this state parameterization method, we use polynomials that ensure that the control variable is non-negative in this model. And increases the time for the model solution to be non-negative compared to conventional methods. The simplicity, lower requirement for mathematical calculations and more compatibility with variables are positive aspects of our parameterization method. Manuscript profile
