The aim of this study was to compare three different diets, namely a high-fat, high-carbohydrate diet (HF-HCD), a high-fat lard-based diet (HFD), and a cafeteria diet (CFD), in terms of the ability to induce METS. The next step was to characterize the syndrome according to the biochemical and histopathological changes in the liver and pancreas, and to determine the optimal animal model. As a result, all diets disturbed significantly the serum biochemical parameters. HF-HCD and CFD increased the uric acid levels and reduced the weight gain in comparison with the standard chow diet (SCD) and HFD. The HFD and CFD induced the highest fasting glycemia levels. Although the animals fed with HF-HCD had the lowest body weight, the most serious histopathological changes in the pancreas, hypertension, and oxidative stress were noted in them.","PeriodicalId":20086,"journal":{"name":"Pharmacia","volume":"9 6","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139009059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing animal models, the investigation assessed the dose-dependent pharmacological effects and safety of H. sabdariffa L.\u0000 Results: The findings indicate that the extract exerts a significant antihypertensive effect at a dose of 250 mg/kg body weight (BW), lowering systolic and diastolic blood pressures by 10.12% and 11.63%, respectively. Ethyl acetate fractions administered at 112.5 mg/kg BW demonstrated greater efficacy than n-hexane and aqueous fractions, suggesting that the active compounds likely possess semi-polar properties. Acute toxicity testing yielded an LD50 of 8.75 g/kg BW for male rats and 7.5 g/kg BW for female rats, classifying the extract as slightly toxic. The sub-chronic toxicity study shows that H. sabdariffa L. demonstrates an effect on bodyweight and urea levels in male and female rats, while the change in the blood parameters, creatinine level, and the liver index was only observed in female rats. Conclusions: These data suggest that H. sabdariffa L. extract exhibits therapeutic promise but should be administered cautiously, preferably at doses lower than 250 mg/kg BW, due to potential toxicity.","PeriodicalId":20086,"journal":{"name":"Pharmacia","volume":"10 10","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139009220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the current study, we investigate the effects of 7 days exposure of rats to simulated microgravity (using a modified rat-modeled random positioning machine, working with four experimental animals simultaneously) on local carrageenan-induced inflammation and serum levels of liver enzymes, metabolites (glucose, urea, creatinine), and metabolic hormones (thyroid-stimulating hormone – TSH, aldosterone, cortisol). Male Wistar rats (n=12, m=200 ± 20 g) were evenly divided into RPM (experimental) and RPM-K (control) groups. The RPM rats showed a notable mass decrease compared to the controls. A significant increase in the carrageenan-induced inflammatory response was reached on the 24th hour in the RPM group compared to the RPM-K. Simulated microgravity resulted in lower serum glucose, creatinine, cortisol, and elevated urea levels. In conclusion, 7 days of exposure to random positioning machine-simulated microgravity promotes a pro-inflammatory state, potentially affecting insulin sensitivity, glucose utilization, and muscle catabolism.","PeriodicalId":20086,"journal":{"name":"Pharmacia","volume":"40 8","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139008401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the first time, a facile technique of increasing the analytical path was applied in this work to enhance the sensitivity. For this purpose, the reaction solutions were photographed using a smartphone while they were contained in two 1-cm pathlength cuvettes which were placed side by side. The Red-Green-Blue (RGB) in term of [B/(R+G+B)] was used to plot a standard curve. Compared to using a single cuvette, double cuvettes resulted in more precise analytical signals and better linearity (r2 of 0.9992). Additionally, CTP could be analyzed at low concentrations (2.5–25 µM) with LOD of 0.70 µM and LOQ of 2.13 µM, thus lowering the reagent consumption. The assay was proven to be valid, and it was greener, faster, and more affordable than the pharmacopeial chromatographic method, thereby suitable for pharmaceutical quality control.","PeriodicalId":20086,"journal":{"name":"Pharmacia","volume":"38 9","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139010452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this comprehensive investigation, we meticulously examined the multifaceted properties of PS through various parameters, including DPPH scavenging activity, total phenol, and total flavonoid content in its ethanol extract (EEPS), ethyl acetate extract (EAPS), and n-hexane extract (nhPS). Additionally, we conducted in-depth assessments of cellular responses to EEPS and EAPS, encompassing cell viability, nitric oxide (NO) production, and the modulation of pivotal pro-inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), and interleukin-12 (IL-12), utilizing the RAW 264.7 cell line as a model system.Our findings illuminate the exceptional antioxidant prowess of PS extracts, with EEPS, EAPS, and nhPS displaying noteworthy DPPH scavenging activities. These results underscore their potential in quenching harmful free radicals and mitigating oxidative stress. Furthermore, our investigation unveils the promising anti-inflammatory attributes of EEPS and EAPS, as evidenced by their capacity to preserve cellular viability, dampen NO production, and suppress the secretion of critical pro-inflammatory mediators (TNF-α, IL-6, IL-1β, and IL-12) in RAW 264.7 cells. These remarkable anti-inflammatory effects hint at the therapeutic potential of PS in ameliorating chronic inflammatory conditions and bolstering the body’s immune response.In conclusion, Polyscias scutellaria stands as an emerging botanical champion, offering a wealth of natural antioxidants and anti-inflammatory compounds that hold great promise for optimizing health and well-being. This study opens exciting avenues for future research to elucidate the precise bioactive constituents within PS and unravel their intricate mechanisms of action, paving the way for the development of innovative therapeutic interventions and wellness-enhancing products.
