Objective: To investigate the association between plasma free amino acids (PFAAs) profile changes, vitamin D concentration and hypertension and evaluate the clinical utility of this association for nascent hypertension before the development of complications. Methods: 70 subjects were enrolled in this study; 50 of them were hypertensive (25 were with uncontrolled hypertensive and 25 were with controlled hypertensive), the other 20 subjects were healthy controls.

Results: Circulating levels of Branched chain amino acids (BCAAs);(valine, leucine, and isoleucine), Aromatic amino acids (AAAs);(phenylalanine, tyrosine, and tryptophan), homocysteine, aspartic, ornithine, asparagine and lysine were elevated significantly in both uncontrolled and controlled hypertensive subgroups in comparison with control group. On the

Background

Quercetin (QR) is one of the major constituents of the methanolic extract of the leaves of Psidium guajava (Guava leaves).

Objectives

The work’s aim is to understand the Quercetin’s mechanism in improving insulin resistance, use the homeostasis model assessment for insulin resistance (HOMA-IR) to determine the influence of quercetin on glycemic control, Look at how quercetin affects diabetes-related lipid metabolism and lipid profile measures. Analyze the impact of QR on oxidative stress in diabetic rats and contrast its antidiabetic effects whether administered as a nutrient or supplement.

Materials and methods

Sixty adult male Wister rats that were matched in age and had starting body weights between 150 and 200 g were used in this study. One normoglycemic control group and 3 diabetic control groups (15 rats per group) were used. The diabetic control rats received the vehicle orally as saline daily, the normoglycemic control group received quercetin orally in a dose of 50 mg/kg per day, and the diabetic rats received quercetin orally in a dose of 100 mg/kg per day.

Results

After six weeks of therapy, the rats with diabetes receiving isolated quercetin at doses of 50 and 100 mg/kg had reduced blood glucose levels, and their triglyceride, low-density lipoprotein, and total cholesterol profiles all significantly improved. Also, there was significant decrease homeostatic model assessment for insulin resistance, serum transaminases, hepatic malondialdehyde, and HMG CoA expression in liver and a substantial rise in levels of insulin, hepatic GSH, and insulin receptor substrate (IRS2) expression & Phosphoinositide 3-kinases in liver as …

Background

The prevalence of obesity is increasing. It is regarded to be among of the world's biggest health issues and the primary factor in metabolic syndrome, a group of illnesses including hypertension, diabetes mellitus, and dyslipidemia. Many studies proved the efficacy of dietary polyphenols ascurcuminand green tea extractin ameliorating obesity and its correlated disorders.

Methods

Our work was the first to explore the impact of green tea extract and curcumin on the insulin-sensitizing anti-inflammatory adipokine C1q/ TNF-related protein-12 (CTRP-12)serum level measured by ELISA and expression of caspase-2 in white adipose tissue invivo measured by qRT-PCR.

Results

We found that both green tea extract and curcumin elevated serum CTRP-12 level. Moreover, they stimulated adipocytes apoptosis via increasing the expression of caspase-2 decreasing adiposity.

Conclusion

The current study concludes that green tea extract and curcumin have prophylactic effect against obesity and obesity-related disorders.Keywords: high-fat diet, caspase-2, CTRP-12, green tea extract, curcumin.

Urothelial carcinoma (UC) of the bladder is a common cause of cancer-related death worldwide. Vasculogenic mimicry (VM) is a process by which the malignant cells can generate vascular-like structures formed of periodic acid–Schiff (PAS) positive/CD31 negative extracellular matrix independent of angiogenesis and thus promotes tumor progression. N-myc downstream–regulated gene 1 (NDRG1) is a protein that can modulate tumor angiogenesis; however, its role in regulating tumor angiogenesis and VM formation has not been previously investigated in UC. This study aims to evaluate the role of intra-tumor microvessel density (MVD) (as a surrogate measure of angiogenesis), VM, and NDRG1 in UC and their correlation with different clinicopathologic features, then assess the correlation between them in UC. Sixty specimens of UC of the bladder were included. PAS-CD31 immunohistochemical double staining method was used to evaluate the intra-tumor MVD and VM. Immunohistochemical expression of NDRG1 was also examined. VM and NDRG1 expression were detected in 41.7% and 83.3% of UC specimens respectively. The mean of intra-tumor MVD, VM area, and NDRG1 was significantly higher in tumors with higher grade, lymphovascular invasion, and higher T stage. NDRG1 expression was positively correlated with MVD and VM. We can suggest that MVD, VM, and NDRG1 may serve as poor prognostic markers for UC. The positive correlation between NDRG1 and both MVD and VM may provide the first evidence that NDRG1 can induce tumor angiogenesis and VM in UC which may offer a novel pathway for further therapeutic strategies.
