Background: The prevalence of non-alcoholic fatty liver disease (NAFLD) has increased in recent decades. There are some concerns about the efficacy and side effects of drugs used for the treatment of NAFLD. Objectives: Therefore, new treatment methods and modalities are needed. This study aimed to determine the efficacy of Beta vulgaris extract in the treatment of NAFLD. Methods: This is a double-blind, parallel-group, randomized clinical trial. This clinical trial was conducted from November 2018 to April 2019 in Shahid Beheshti Hospital of Kashan, Iran. Among 143 NAFLD patients who met the inclusion criteria, 120 patients agreed to participate in the study. Subsequently, they were divided into two equal groups via simple randomization. The Beta vulgaris group received Beta vulgaris extract, alongside standard NAFLD treatment, including vitamin E and Silybum marianum extract (Livergol). The placebo group received standard NAFLD treatment, as well as a placebo instead of Beta vulgaris extract. The levels of aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), fasting blood sugar (FBS), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were evaluated and compared between the groups. Variables were measured at the beginning of the study and after three and six months. Results: Overall, 52% of the participants were male. The mean (SD) age of Beta vulgaris and placebo groups was 47.5 (10.5) and 46.4 (8.7) years, respectively. The results of between-group analysis revealed that AST significantly reduced in the Beta vulgaris group, compared to the placebo group (P = 0.04). Conversely, ALT reduction was not significant in the groups. The significant interaction between time and groups indicated that the effect of Beta vulgaris on ALT increased over time (P < 0.001). Moreover, the ALP, FBS, LDL, and HDL levels significantly improved in the Beta vulgaris group compared to the placebo group (P < 0.05). Conclusions: Integration of Beta vulgaris extract in the standard treatment of NAFLD could significantly improve AST, ALP, FBS, LDL, and HDL. This study also revealed that the effect of Beta vulgaris on ALT increased over time.
Background: Bone tissue engineering has shown to be a promising strategy for repairing bone defects without causing harmful side effects to the patient. Three main building blocks of tissue engineering, including seeding cells, scaffold, and signaling molecules, are required for adequate bone regeneration. The hAM is the innermost of the placental membranes. In addition to providing a source of stem cells and growth factors, hAM has several features that make it an appropriate scaffold containing stem cells for use in tissue engineering purposes. The present investigation aimed to assess the effect of BMP-9 combined with phenamil and simvastatin on osteogenic induction of hAM with its hAECs. Methods: Using six different OMs, we cultured hAM for 14 days. The basic OMs were chosen as the first group and other media were made by adding BMP-9, phenamil, simvastatin, BMP-9 alongside phenamil, and BMP-9 alongside simvastatin to the basic OMs. Finally, viability assay, tissue mineralization, calcium and phosphate content determination, and measurement of LDH, and ALP activity were performed.Results: Among all study groups, groups containing simvastatin showed a significantly lower level of viability. Although all media could induce osteogenic features, the hAECs cultured in media containing BMP-9 and phenamil demonstrated a wider area of mineralization and a significantly higher level of calcium and phosphate content, LDH, and ALP activity. Conclusion: Our findings indicated that the use of phenamil together with BMP-9 could synergistically show in situ osteogenic induction in hAECs, which could be a new insight into translational medicine.
Background: Autoimmune thyroid diseases are among the most common autoimmune diseases in the world. They are usually accompanied by the presence of anti-thyroid antibodies as the early predictive marker. Genetic determinants of the susceptibility to develop thyroid antibodies are still poorly understood. This study aimed to investigate the relation between thyroid peroxidase (TPO) gene variants (53 SNPs) and positive TPOAb and also to evaluate the effect of some environmental factors on changes from negative to positive TPOAb (Seroconversion). Methods: Participants from the Tehran Thyroid Study (TTS) in phases 1 and 2 (N=5317, ≥ 20 years) were evaluated for the positive TPOAb and its relationship with 53 SNPs from TPO gene (a cross-sectional approach). At the second stage of the study (a longitudinal approach), negative TPOAb participants (control group, N= 4815) were followed up for about 5.5 (5.54±1.62) years until they have had positive results for TPOAb (“TPOAb seroconversion”). The association between TPO gene polymorphisms and TPOAb seroconversion was evaluated using logistic regression analysis and SKAT package (sequence kernel association test). Results: In cross-sectional analyses, 17 SNPs were associated with TPOAb positivity (521 positive TPOAb participants) after the adjustment for age, sex, body mass index (BMI), smoking, the number of parity and oral contraceptive consumption (P <0.05). In longitudinal analyses, there was an association between TPOAb seroconversion and four SNPs before, and three SNPs after adjustment (P <0.05). Conclusions: TPOAb seroconversion could be affected by some thyroid peroxidase gene variants.
: Considering that there are different reports about the effects of angiotensin II type-I receptor blockers (ARB) and angiotensin-converting enzyme inhibitors (ACEI) on the outcomes of the patients with COVID-19, we aimed to conduct this retrospective study on 138 hypertensive patients (81 ACEI/ARB users) to assess the patients’ outcomes by comparing ACEI/ARB and non-ACEI/ARB users. Multivariate adjusted cox regression model, by considering the effect of other variables, demonstrated that increased age (HR = 1.04, 95% CI = 1.01 -1.07, P =0.003) and non- ACEI/ARB users (HR = 2.12 95% CI = 1.12 - 4.13, P = 0.021) were associated with increased risk of in-hospital mortality in about one week follow-up. In conclusion, we found that in-hospital mortality was lower in ACEI/ARB users, showing the positive effect of these treatments on patients’ outcomes.
