Effect of imidazoline-1 receptor agonists on renal dysfunction in rats associated with chronic, sequential fructose and ethanol administration.

Insulin resistance and chronic alcoholism are risk factors for renal dysfunction. This study investigated the therapeutic effects of two imidazoline-1 receptor (I1R) agonists on renal dysfunction in rats after chronic, sequential fructose and ethanol administration. Daily drinking water was supplemented with fructose (10%, w/v) for 12 weeks and then with ethanol (20%, v/v) for another 8 weeks.

Beta-caryophyllene alleviates diet-induced neurobehavioral changes in rats: The role of CB2 and PPAR-γ receptors.

Background And Purpose: Insulin resistance (IR) and obesity predispose diseases such as diabetes, cardiovascular and neurodegenerative disorders. Beta-caryophyllene (BCP), a natural sesquiterpene, exerts neuroprotective, anxiolytic and antidepressant effects via its selective agonism to cannabinoid receptor 2 (CB2R). BCP was shown to have an anti-diabetic effect, however, the implication of CB2R is yet to be elucidated.

Rutin and orlistat produce antitumor effects via antioxidant and apoptotic actions.

Cancer is a broad term used to describe a large number of diseases characterized by uncontrolled cell proliferation that leads to tumor production. Cancer is associated with mutations in genes controlling proliferation and apoptosis, oxidative stress, fatty acid synthase (FAS) expression, and other mechanisms. Currently, most antineoplastic drugs have severe adverse effects and new effective and safe drugs are needed.

Beta-caryophyllene protects against diet-induced dyslipidemia and vascular inflammation in rats: Involvement of CB2 and PPAR-γ receptors.

Beta-caryophyllene (BCP) is a phytocannabinoid possessing selective agonistic activity to cannabinoid type-2 receptors (CB2R) and peroxisome proliferator-activated receptors-α (PPAR-α). However, few studies reported the contribution of PPAR-γ receptors in BCP effects. The aim of this study was to investigate the BCP effects on diet-induced dyslipidemia and vascular inflammation as well as the involvement of CB2R and PPAR-γ receptors.

Ameliorative effects of clonidine on ethanol induced kidney injury in rats: Potential role for imidazoline-1 receptor.

Chronic alcoholism is a risk factor for kidney injury. Clonidine is an α-adrenergic receptor/imidazoline-1 receptor agonist that can reduce blood pressure and maintain renal functions. This study aims to investigate the possible ameliorative effects of clonidine on ethanol induced kidney injury and its mechanism of action.

Effect of cardamonin on hepatic ischemia reperfusion induced in rats: Role of nitric oxide.

Ischemia reperfusion (I/R) injury is a cellular damage in a hypoxic organ following the restoration of oxygen delivery. It may occur during organ transplantation, trauma and hepatectomies. Nitric oxide (NO) effects during hepatic I/R are complicated.

Anticancer activity of salicin and fenofibrate.

Cancer refers to a disorder of cell proliferation that leads to tumor production. Cancer is usually treated by surgery, chemotherapeutic drugs, and radiation. Despite the presence of many anticancer drugs, cancer is still an uncontrolled disease and is a major cause of death worldwide.

Quercetin and tin protoporphyrin attenuate hepatic ischemia reperfusion injury: role of HO-1.

Ischemia reperfusion (IR) injury occurs in many clinical situations such as organ transplantation and hepatectomies resulting in oxidative stress and immune activation. Heme oxygenase-1(HO-1) is the rate-limiting step in the heme-degradation pathway and has a critical cytoprotective role. Induction of HO-1 improves liver I/R injury.

The effects of tramadol on hepatic ischemia/reperfusion injury in rats.

Objectives: Tramadol is a centrally acting synthetic analgesic. It has a cardioprotective effect against myocardial ischemia-reperfusion (I/R) injury in isolated rat heart. We hypothesized that tramadol may exert a similar protective effect on hepatic I/R injury.

Limonin attenuates hepatocellular injury following liver ischemia and reperfusion in rats via toll-like receptor dependent pathway.

Limonin has been shown to exhibit anti-inflammatory and antioxidant properties in the settings of chemically induced hepatic injury. The current study aimed to investigate the protective effects of limonin on experimentally-induced hepatic ischemia reperfusion (I/R) injury in rats. Rats were injected IP with either DMSO or limonin (100 mg/kg BW), 30 min before submission to 45 min of ischemia, followed by 1 h of reperfusion.

Haem oxygenase-1 induction protects against tumour necrosis factor alpha impairment of endothelial-dependent relaxation in rat isolated pulmonary artery.

Background And Purpose: Disturbances in pulmonary vascular reactivity are important components of inflammatory lung disease. Haem oxygenase-1 (HO-1) is an important homeostatic enzyme upregulated in inflammation. Here we have investigated the potentially protective effect of HO-1 against cytokine-induced impairment in pulmonary artery relaxation.
