This study aimed to examine the hepatic and anti-steatotic protective effects of methanolic extract from Carthamus tinctorius (safflower) flowers (SFFE), using a rat model of type 2 diabetes mellitus (T2DM), and to examine the molecular mechanisms underlying these effects. Adult male Wistar rats were used for this study. First, T2DM was induced in some rats by feeding them a high-fat diet (HFD) for 4 weeks, followed by a single dose of streptozotocin (STZ) (35 mg/kg, i.p.). Experimental groups included the following five groups (n = 8 in each): control, control + SFFE, T2DM, T2DM + SFFE, and T2DM + SFFE + brusatol (an Nrf2 inhibitor, 2 mg/kg, i.p.). SFFE was administered at a concentration of 300 mg/kg, and all experiments concluded after 8 weeks. Treatments with SFFE significantly reduced fasting blood glucose levels, free fatty acids (FFAs), cholesterol, triglycerides, and low-density lipoprotein cholesterol in both the control and T2DM rats, but they failed to reduce fasting insulin levels in these groups. SFFE treatments also improved the liver structure and reduced hepatocyte vacuolization and hepatic levels of triglycerides and cholesterol in T2DM rats, in addition to increasing the hepatic mRNA levels of keap1 and the cytoplasmic levels and nuclear activities of Nrf2 in both the control and T2DM rats. SFFE also stimulated the expression levels of PPARα and CPT-1 but reduced the malondialdehyde (MDA), mRNA levels of SREBP1, fatty acid synthase, and acetyl CoA carboxylase in both the control and T2DM rats; meanwhile, it reduced hepatic mRNA and the nuclear activities of NF-κB and increased levels of glutathione, superoxide dismutase, and heme oxygenase-1 in the livers of both groups of treated rats. Furthermore, SFFE suppressed the levels of caspase-3, Bax, tumor necrosis factor-α, and interleukin-6 in the T2DM rats. Treatment with brusatol prevented all of these effects of SFFE. In conclusion, SFFE suppresses liver damage and hepatic steatosis in T2DM through Nrf2-dependent hypoglycemic, antioxidant, anti-inflammatory, and hypolipidemic effects. [ABSTRACT FROM AUTHOR]

Objective: This study compared the ability of Liquorice roots aqueous extract (LRE) and its ingredient, isoliquiritigenin (ISL), in alleviating high-fat diet (HFD)-induced hepatic steatosis and examined if this effect involves activation of AMPK. Materials and methods: Control or HFD-fed rats were treated with the vehicle, LRE (200 mg/kg), or ISL (30 mg/kg) for 8 weeks orally. Results: ISL and LRE reduced HFD-induced hyperglycaemia, improved liver structure, lowered serum and hepatic lipids, and attenuated hepatic oxidative stress and inflammation. In the control and HFD-fed rats, ISL and LRE significantly stimulated the muscular and hepatic mRNA and protein levels of AMPK, improved oral glucose tolerance, reduced hepatic mRNA levels of SREBP1/2, and upregulated hepatic levels of PPARα and Bcl2. These effects were comparable for ISL and LRE and were prevented by co-administration of compound C, an AMPK inhibitor. Discussion and conclusion: ISL and LRE provide an effective theory to alleviate hepatic steatosis through activating AMPK. [ABSTRACT FROM AUTHOR]

Background and Objectives: Diabetes mellitus is a chronic metabolic disease associated with several complications, including that of kidney disease. Plant-based dietary products have shown promise in mitigating these effects to improve kidney function and prevent tissue damage. This study assessed the possible favorable effects of beetroot extract (BE) in improving kidney function and preventing tissue damage in diabetic rats. Materials and Methods: Type 2 diabetes mellitus (T2DM) was induced using a low dose of streptozotocin (STZ). Both control and rats with pre-established T2DM were divided into six groups (each consisting of eight rats). All treatments were given by gavage and continued for 12 weeks. Fasting blood glucose levels, serum fasting insulin levels, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), serum triglycerides, cholesterol, low-density lipoprotein-cholesterol, serum and urinary albumin, and creatinine and urea levels were measured. Apart from this, glutathione, malondialdehyde, superoxide dismutase, tumor necrosis factor-α, and interleukine-6 in the kidney homogenates of all groups of rats were measured, and the histopathological evaluation of the kidney was also performed. Results: It was observed that treatment with BE increased body weight significantly (p ≤ 0.05) to be similar to that of control groups. Fasting glucose, insulin, HOMA-IR levels, and lipid profile in the plasma of the pre-established T2DM rats groups decreased to p ≤ 0.05 in the BE-treated rats as the BE concentration increased. Treatment with BE also improved the renal levels of oxidative stress and inflammatory markers, urinary albumin, and serum creatinine and urea levels. Unlike all other groups, only the kidney tissues of the T2DM + BE (500 mg/kg) rats group showed normal kidney tissue structure, which appears to be similar to those found in the kidney tissues of the control rats groups. Conclusion: we found that streptozotocin administration disturbed markers of kidney dysfunction. However, Beta vulgaris L. root extract reversed these changes through antioxidant, anti-inflammatory, and antiapoptotic mechanisms. [ABSTRACT FROM AUTHOR]

Exposure to allergens could be life-threatening for people with food allergies. Restaurants and cafes are challenging environments for accommodating food allergies. This study aimed to measure King Saud University female students' awareness about food allergens on restaurants' and cafes' menus. This cross-sectional study was conducted on 379 students aged 18 years and above. A paper-based questionnaire was used, which comprised 16 questions related to the definition of food allergies, food allergens, and food allergy symptoms; the definition and prevention of cross-contact of food allergies; emergency treatment procedures for food allergies; strategies for the prevention of food allergy reactions; customer expectations towards restaurants; and preventive measures taken for food allergies. The results indicate that the overall average score of food allergen awareness was 10.90, which falls in the higher range. Furthermore, female students in the age groups of 23 to 27 years and 33 to 37 years had higher levels of awareness than female students in the age group of 18 to 22 years. The results also showed that the level of awareness among science college and health college students was statistically significantly higher (p < 0.05) than that among humanities college students. Post-graduate students also showed a higher level of awareness of food allergens than bachelor's students. These findings also indicate that listing all allergens in the restaurants and cafes' menus statistically significantly (p < 0.05) increased the level of awareness of female students about food allergens on restaurants' and cafes' menus, compared to restaurants and cafes that do not list all allergens on their menus. In general, female students at King Saud University showed a high level of awareness about food allergies on restaurants' and cafes' menus. The study recommends assessing the impact of awareness of female students with and without food allergies on their practices and behaviors. [ABSTRACT FROM AUTHOR]

Introduction: labels deliver basic product information, health safety and nutritional information. Objectives: this study aims to assess consumers’ knowledge, awareness, and practices in relation to food labels and the effect of sociodemo)graphic characteristics on various aspects of food labels in Al-Ahsa. Methods: a random sampling method was used to recruit participants (n = 403) and a validated electronic questionnaire was used to gather data. Results: most of the participants (81.4 %) had moderate knowledge about general nutrition. The majority of them (58.8 %) placed high impor)tance on reading food labels. Participants have positive opinions about the significance of reading food labels, and practice most of its aspects on a “frequent” basis. Lack of time was the main barrier for not utilizing food label information and obesity was the main concern if they did not read food labels. Results also demonstrate significant (p ≤ 0.01) positive correlations between participants’ nutrition knowledge and their rating of the significance and their opinion and practices of reading food labels. Participants’ rating of the importance of reading food labels was positively correlated with participants’ opinion and practices regarding food label. Results also indicate that participants’ sex, age, body mass index, educational level and health status have significant (p ≤ 0.05) effects on various aspects of food label under study. Finally, this study suggests some actions are required to enrich the knowledge, awareness, and practices regarding the food label among Saudi consumers in Al-Ahsa. Conclusion: this study emphasizes the significance of education and awareness initiatives to empower consumers to understand and use nutrition facts labels in order to make healthy dietary choices.
