Abstract
It is well known, that the inflammatory process that characterizes acute pancreatitis (AP) can lead to both pancreatic damage and systemic inflammatory response syndrome (SIRS). During the last 20 years, there has been a growing incidence of episodes of acute pancreatitis associated with hypertriglyceridaemia (HTAP). This review provides an overview of triglyceride metabolism and the potential mechanisms that may contribute to developing or exacerbating HTAP. The article comprehensively discusses the various pathological roles of free fatty acid, inflammatory response mechanisms, the involvement of microcirculation, serum calcium overload, oxidative stress and the endoplasmic reticulum, genetic polymorphism, and gut microbiota, which are known to trigger or escalate this condition. Future perspectives on HTAP appear promising, with ongoing research focused on developing more specific and effective treatment strategies.

Air pollution combined with high-fat feeding aggravates metabolic and cardiovascular diseases: A dangerous, oxidative, and immune-inflammatory association. Life Sci 2023; 317:121468. [PMID: 36736766 DOI: 10.1016/j.lfs.2023.121468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 01/19/2023] [Accepted: 01/29/2023] [Indexed: 02/04/2023]
Abstract
Obesity and particulate air pollutant (PM2.5) are important risk factors for cardiometabolic diseases. PM2.5 exacerbates insulin resistance and lipid ectopic deposition in obese animals. The inorganic fraction of PM2.5, the Residual Oil Fly Ash (ROFA), is related to cardiovascular events, by enhancing the generation of reactive species, inflammatory cytokines, and leukocyte activation. However, the synergistic effects of ROFA and a high-fat diet (HFD) are still poorly described, and the studies were mainly conducted with males. AIMS To investigate if ROFA could potentiate the cardiometabolic effects of diet-induced obesity in female rats. MATERIAL AND METHODS Wistar female rats were divided into four groups: Control (n = 6), Polluted (n = 6), HFD (n = 6), and HFD + Polluted (n = 6). HFD and HFD + Polluted received a high-fat diet (HFD) (58.3 % as fats), whilst Control and Polluted groups received a standard diet (Nuvilab CR-1). In addition, Polluted and HFD + Polluted groups received intranasal instillation of ROFA (250 μg/50 μL), while Control and HFD groups received saline solution (50 μL) daily, five days per week. Both interventions occurred 24 weeks after the animals were euthanized. KEY FINDINGS HFD combined with ROFA exposure impaired lipid profile challenged systemic and cardiac antioxidant defense, and presented a synergistic effect in inducing an immune-inflammatory condition. We found that the lipid profile disturbance is associated with HFD-induced hepatic, but not cardiac, deposition of triglycerides in female animals. SIGNIFICANCE Our results support the hypothesis that ROFA exposure combined with bad feeding can exacerbate metabolic and cardiovascular diseases.

Abstract
This study assessed the effects of a mixed formulation containing Limosilactobacillus (L.) fermentum 139, L. fermentum 263, and L. fermentum 296 on cardiometabolic parameters, inflammatory markers, short-chain fatty acid (SCFA) fecal contents, and oxidative stress in colon, liver, heart, and kidney tissues of female rats fed a high-fat diet (HFD). Female Wistar rats were allocated into control diet (CTL, n = 6), HFD (n = 6), and HFD receiving L. fermentum formulation (HFD-LF, n = 6). L. fermentum formulation (1 × 109 CFU/mL of each strain) was administered two twice a day for 4 weeks. Administration of L. fermentum increased acetate and succinate fecal contents and reduced hyperlipidemia and hyperglycemia in rats fed a HFD (p < 0.05). Administration of L. fermentum decreased low-grade inflammation and improved antioxidant capacity along the gut, liver, heart, and kidney tissues in female rats fed a HFD (p < 0.05). Administration of L. fermentum prevented dyslipidemia, inflammation, and oxidative stress in colon, liver, heart, and kidney in female rats fed a HFD.

The effects of long-term moderate exercise and Western-type diet on oxidative/nitrosative stress, serum lipids and cytokines in female Sprague Dawley rats. Eur J Nutr 2021; 61:255-268. [PMID: 34319428 PMCID: PMC8783884 DOI: 10.1007/s00394-021-02639-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Accepted: 07/05/2021] [Indexed: 11/25/2022]
Abstract
Purpose Regular exercise reduces obesity and the risk of cardiovascular disease. However, health-promoting benefits of physical activity are commonly associated with increased inflammation and oxidative stress. Here, we tested whether constant moderate exercise is able to prevent or attenuate the oxidative/nitrosative stress, inflammation, and serum lipids in lean and obese rats. Methods Four-month-old female Sprague Dawley rats received standard or a high-fat diet. Animals were subjected to a physical activity protocol, consisting of 30 min forced treadmill exercise for 5 consecutive days per week during 10 months. Baseline and sedentary (non-exercised) rats were used as controls. Lipids, oxidized low-density lipoprotein cholesterol, nitric oxide metabolites, and pro- and anti-inflammatory markers were measured in blood collected upon euthanasia. Results At variance to young baseline control rats, 14-month-old animals fed normal diet had increased plasma lipid levels, including total cholesterol and triglycerides, which were further elevated in rats that consumed a high-fat diet. While treadmill exercise did not lower the amount of serum lipids in standard diet group, forced physical activity reduced non-high-density lipoprotein cholesterol in response to high-fat diet feeding. Exercised rats fed standard diet or high-fat diet had lower abundancy of nitric oxide metabolites, which coincided with increased levels of oxidized low-density lipoprotein cholesterol. Accordingly, the amount of nitric oxide metabolites correlated inversely with oxidized low-density lipoprotein cholesterol and homo-arginine. Exercise significantly reduced inflammatory cytokines in high-fat diet fed rats only. Conclusion Our study suggests that regular exercise alters the equilibrium between oxidative and anti-oxidative compounds and reduces pro-inflammatory cytokines.

Binahong ( Anredera cordifolia (Tenore) Steen.) Leaf Extract Modulates Fatty Acids and Amino Acids to Lower Blood Glucose in High-Fat Diet-Induced Diabetes Mellitus Rats. Adv Pharmacol Pharm Sci 2021; 2021:8869571. [PMID: 34007967 PMCID: PMC8100415 DOI: 10.1155/2021/8869571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Revised: 03/14/2021] [Accepted: 04/24/2021] [Indexed: 12/02/2022] Open
Abstract
Patients with diabetes are 1.6 times more likely to use complementary alternative medicine than nondiabetic patients. Previous studies have shown that Anredera cordifolia (Tenore) Steen. (A. cordifolia) leaf extract has the capacity to lower blood glucose, but the actual mechanisms are unclear. Therefore, in this study, we explored the effect of A. cordifolia leaf extract on the metabolism of fatty acids and amino acids. Six-week-old male Wistar rats were randomly divided into six experimental groups (n = 5 per group). Two groups were fed with a regular diet or a high-fat diet (HFD) for six weeks. The regular diet and HFD groups were administered with 0.5% carboxymethylcellulose as a vehicle, and HFD rats were also fed with a suspension of glibenclamide (0.51 mg/kg body weight (BW)) or A. cordifolia leaf extract (25, 50, and 100 mg/kg BW). During the whole treatment, BW and food intake were recorded weekly. The rats were euthanized seven weeks after treatment. Blood glucose was evaluated by spectrophotometry, while fatty acids and amino acids were evaluated using a gas chromatography/flame ionization detector (GC/FID). All doses of A. cordifolia administration reduced blood glucose significantly, and 50 mg/kg BW was most effective in lowering blood glucose, similar to the effects of glibenclamide. A. cordifolia leaf extract affected the levels of medium-chain fatty acids, especially at 50 mg/kg BW. In contrast, glibenclamide affected long-chain fatty acids (LCFAs) to lower blood glucose. Based on the analysis conducted, we conclude that administration of A. cordifolia leaf extract can decrease blood glucose levels by regulating fatty acid metabolism and that a dose of 50 mg/kg BW in rats was the optimal dose.

Abstract
Several studies have shown that probiotics and synbiotics ameliorate dyslipidemia. However, the molecular mechanisms mediating their effects remain to be determined. Therefore, we aimed to compare the effects of a probiotic, a prebiotic, and a synbiotic in dyslipidemic Sprague–Dawley rats, and explore the mechanisms involved using a proteomic approach. The rats were allocated to five groups: a control group that was fed normal chow, and four high-fat diet-fed groups, three of which were administered a probiotic (Lactobacillus acidophilus), a prebiotic (inulin), or a combination of the two (a synbiotic) for 30 days. We showed that the administration of inulin, and especially L. acidophilus, improved the lipid profile and reduced the serum concentrations of inflammatory markers in high-fat diet-fed rats. Proteomic analysis showed changes in lipid elongation, glycerolipid metabolism, activation of antioxidants, and a reduction in the activation of the mitogen-activated protein kinase signaling pathway in the livers of rats administered L. acidophilus, which likely mediate its beneficial effects on inflammation and dyslipidemia by reduced the levels of 18.56% CRP, 35.71% TNF-α 25.6% LDL-C and 28.57% LDL-C/HDL-C ratio when compared to HF group. L. acidophilus and inulin may represent effective natural means of maintaining inflammation and dyslipidemia.

[PMID: 33494143 PMCID: PMC7909836 DOI: 10.3390/ani11020258] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 01/16/2021] [Accepted: 01/19/2021] [Indexed: 12/12/2022] Open
Abstract
Simple Summary High-fat (HF) diet induces both immune-mediated damage and trefoil factor family member 2 (Tff2) expression. As TFF2 has tissue repair and protection properties, this suggests that HF diet-induced Tff2 production and the resulting TFF2 mucosal protective effects would be a mechanism to counteract the HF diet-induced tissue damage. On the other hand, the induction of Tff2 by HF diet could indicate that TFF2 is a food intake regulator (appetite control) since Tff2 is also expressed in the brain. This highlights the importance of exploring TFF2-related pathways in the context of obesity management towards potential therapies. Abstract Physiological homeostasis requires a balance between the immunological functions and the resulting damage/side effects of the immunological reactions including those related to high-fat (HF) diet. Within this context, whereas HF diet, through diverse mechanisms (such as inflammation), leads to immune-mediated damage, trefoil factor family member 2 (Tff2) represents a HF diet-induced gene. On the other hand, TFF2 both promotes tissue repair and reduces inflammation. These properties are towards counteracting the immune-mediated damage resulting from the HF diet. These observations suggest that the HF diet-induction of Tff2 could be a regulatory pathway aiming to counteract the immune-mediated damage resulting from the HF diet. Interestingly, since Tff2 expression increases with HF diet and with Tff2 also expressed in the brain, we also hypothesize that TFF2 could be a HF diet-induced food intake-control signal that reduces appetite. This hypothesis fits with counteracting the immune damage since reducing the food intake will reduce the HF intake and therefore, reduces the HF diet-induced tissue damage. Such food intake signaling would be an indirect mechanism by which TFF2 promotes tissue repair as well as a pathway worth exploring for potential obesity management pharmacotherapies.
