The modulation of PCSK-9 and GAGs by 10-dehydrogingerdione and pentoxifylline in hyperlipidemic rabbits

High-Intensity Interval Training Enhances the Positive Effect of Pentoxifylline on Lipid Profile and Inflammatory Markers in an Endometriosis Animal Model

Background: The relationship between endometriosis and cardiovascular disease (CVD) is well established. However, the effects of various exercise training modalities and the anti-inflammatory effects of pentoxifylline (PTX) remain inadequately understood. This investigation is aimed at evaluating the effects of PTX, both independently and in conjunction with high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT), on lipid and inflammatory markers including triglycerides (TGs), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and C-reactive protein (CRP) in a rat model of endometriosis. Materials and Methods: Sprague-Dawley's rats were divided into two primary groups: the healthy control group that received no intervention and the induced endometriosis group. Endometriosis was surgically induced in rats, and those with confirmed endometriotic lesions were further categorized into six groups: control, MICT, drug of PTX (D), MICT+D, HIIT, and HIIT+D. Two weeks after laparotomy, PTX consumption and exercise training were performed for 8 weeks. PTX was administered orally at 100 mg/kg/day. MICT and HIIT sessions were conducted 5 days per week, with MICT beginning at 55% of maximum capacity for 31 min in the first week and progressing to 70% of maximum capacity for 46 min by the eighth week. HIIT sessions consisted of 2 min of running followed by 1 min of passive rest at 85% of maximum capacity, starting with seven intervals in the first week and increasing to twelve by the end of the eighth week. The macroscopic size of endometriosis lesions was measured, and cardiovascular risk factors, including hs-CRP, TC, TG, HDL-C, and LDL-C, were assessed in serum samples. Results: The induction of endometriosis was associated with elevated cardiovascular risk factors, including hs-CRP, TC, and TG. HIIT+D significantly decreased lesion volume (p < 0.0001, 95%confidence interval (CI) = 57.239-94.718), hs-CRP (p = 0.049, CI = -54.083 to - 29.478), TC (p = 0.045, CI = -38.607 to - 25.392), and TG (p = 0.042, CI = 25.531-55.801). PTX significantly decreased lesion volume (p < 0.0001, CI =34.709-73.919) and TC (p = 0.016, CI = -45.153 to - 30.179). Conclusion: All interventions except MICT reduced lesion volume, whereas only HIIT+PTX and PTX, in the order of importance, improved some cardiovascular risk indices in the rat model of endometriosis.

10-dehydrogingerdione amends tramadol-elicited neurotransmitters disturbance and apoptosis in the brain of male rats by repleting non-enzymatic antioxidants

Tramadol is analgesic medication to relief acute and chronic pain, referred to as alternative to opioid drugs however its abuse or overdosage may resulted in neuronal toxicity. This is attributed to severe fluctuations of neurotransmitters pattern along with cerebral inflammation and oxidative damage. Present work was undertaken to illustrate the cytoprotective effect of 10-dehydrogingerdione (10-DHGD) on the brain tissues of experimental rats due to Tramadol intake and its underlying mechanism. 24 male wistar rats were randomized into 4 equal groups. Group (1), received tramadol in a dose level 20 mg/kg intrapertioneal (i.p) daily for 30 days and referred to Tramadol group. Group (2), received both of 10-DHGD (10 mg/kg, orally) one hour before tramadol intake (dose as mentioned before) daily for 30 days. Group (3) received 10-DHGD only (10 mg/kg, orally) and daily for 30 days. Group (4), received no drugs and referred to control group for comparison. Tramadol significantly reduced Norepinephrin (NE), dopamine, serotonin and glutathione (reduced) contents of Cerebral cortex. lipid peroxidation, nuclear factor kappa B (NFkB), inducible nitric oxide synthase (INOS) levels and caspase-3 immunoreactivity showed however significant increase. Of note, 10-DHGD significantly increased neurotransmitters, glutathione contents while Malondialdehyde (MDA), Nitric oxide (NO), NFkB, INOS additionally caspase-3 immunoexpression showed significant decrease i.e counteracted to certain extent tramadol effect. These findings may refer to the cytoprotective potential of 10-DHGD against the neurotoxicity exerted by tramadol intake, most probably mediated via enhancement of endogenous antioxidants system.

Nutritional benefits of ginger for patients with non-communicable diseases

Ginger (Zingiber officinale) is a famous dietary spice rich in bioactive components like gingerols, and it has been used for a long time as food and medicine. Indeed, clinical studies have confirmed the anti-inflammatory and antioxidant properties of ginger. Thus, ginger seems to be an excellent complementary nutritional strategy for non-communicable diseases (NCD) such as obesity, diabetes, cardiovascular disease and chronic kidney disease. This narrative review aims to discuss the possible effects of ginger on the mitigation of common complications such as inflammation, oxidative stress, and gut dysbiosis in NCD.

Early myocardial injury biomarkers in diabetic hyperlipidemic rats: Impact of 10-dehydrogingerdione and vitamin D3

Hyperlipidemia represents a major risk factor for cardiovascular diseases leading to myocardial injury (MI). The present study aimed to illustrate the pattern of myocardial injury induced in diabetic hyperlipidemic rat model and the effect of vitamin D3, 10-dehydrogingerdione (10-DHGD) intake either individually or in combination form.
