The contamination of edible agricultural goods with pesticides, including dichlorvos (DVDP), poses a substantial public health risk, promoting severe morbidity and mortality, especially in developing countries. It has been shown that hesperidin (hesperetin-7-O-rhamnoglucoside or Hes-7-RGlc) preserves cytomembrane, redox, and lipid homeostasis; unfortunately, its function on dichlorvos-incited heart damage has not been investigated. This work explored the ameliorative influence of Hes-7-RGlc on DVDP-activated cardiotoxicity.

Background And Aims: Obesity-related heart failure is exacerbated by excessive intake of saturated fats such as palmitate (PA). Lycopene (LYC) possesses anti-lipidemic, antioxidant, cytoprotective, and anti-inflammatory effects. This study, therefore, evaluated the impact of LYC against PA-invoked cardiotoxicity.

Alcohol consumption is known to cause an array of alcohol-induced biochemical changes in a biological system. This study investigated the durations effects of different alcohol concentrations (30%, 40%, and 50%) on malondialdehyde levels, testes histology, and sperm characteristics in matured male Wistar rats. The rats were divided into four groups namely thus; control, 30%, 40% and 50%.

Article Synopsis
  • Endocrine-disrupting pollutants (EDPs) like Bisphenol S (BPS) and diethyl phthalates (DEP) are common environmental toxins that may cause neurotoxicity, which was examined in male Wistar rats.
  • Exposure to a mixture of BPS and DEP resulted in anxiety-like behaviors, cognitive and motor impairments, and increased oxidative stress markers.
  • Treatment with morin showed protective effects by improving neurobehavioral outcomes, reducing enzyme hyperactivity, and decreasing oxidative stress and inflammation in the rats.

Hepato-renal dysfunctions associated with hyperlipidemia necessitates a continuous search for natural remedies. This study thus evaluated the effect of dietary chitosan on diet-induced hyperlipidemia in rats. A total of 30 male Wistar rats (90 ± 10) g were randomly allotted into six (6) groups ( = 5): Normal diet, High-fat diet (HFD), and Normal diet + 5% chitosan.

Earlier reports have shown that Cyclophosphamide (CYCP), an anti-malignant drug, elicited cytotoxicity; and that naringin has several beneficial potentials against oxidative stress and dyslipidaemias. We investigated the influence of naringin on free radical scavenging, cellular integrity, cellular ATP, antioxidants, oxidative stress, and lipid profiles in the CYCP-induced erythrocytotoxicity rat model. Rats were pretreated orally by gavage for fourteen consecutive days with three doses (50, 100, and 200 mg/kg) naringin before single CYCP (200 mg/kg, i.

Neuroinflammation can be triggered by certain high caloric nutrients such as palmitic acid (PA). The effect of lycopene against PA-induced neuroinflammation in female rats has not been as explored. In the present study, thirty rats (weighing 150-200) g were randomly allotted into six groups (n = 5) comprising normal control, PA control, PA + lycopene (0.

Given the unrelenting surge in the prevalence of obesity and the intensified efforts aimed at elucidating underlying mechanisms and proffering effective treatments, this study investigated the effects of lycopene on various anthropometrical indices of obesity. Thirty female Wistar rats were equally divided into two groups and fed either control diet or Western diet. After eight weeks, obese rats (fed Western diet) were divided into three groups (n=5); obese control received the vehicle, while the other two received lycopene (0.

Non-alcoholic fatty liver disease (NAFLD) is a hepatic condition with multiple pathological features and it currently has no specific treatment or approved drug. Wonderful kolanut widely consumed fresh or cooked has been applied in the treatment of numerous diseases in folk medicine. In this study, we evaluate the therapeutic potentials of hydroethanolic extract of defatted Buccholzia coriacea seeds (HEBCS) in NAFLD model.

Background And Aim: Diabetes is a major cause of death worldwide and currently available allopathic drugs presents adverse side effects, thus, necessitating a continuous screening for natural products. This study therefore investigated the effects of Propolis Ethanol Extract (PEE) on blood sugar, lipid metabolism, and poly-(ADP)-ribose polymerase (PARPs) protein level of diabetic male Wistar rats.

Methodology: Seventy rats weighing between (150-180) g used in this study were randomized into seven (7) groups as follows: group 1 (Normal control given Olive oil), group 2 (Diabetic control given Olive oil), group 3 [Diabetic + PEE (200 mg/kg)], group 4 [Diabetic + (PEE 600 mg/kg)], group 5 [Diabetic + Glibenclamide (10 mg/kg)], group 6 [Normal + PEE (200 mg/kg)], and group 7 [Normal + PEE (600 mg/kg)].

Extracts of (CA) have been reported to possess medicinal properties ranging from potential hepatoprotective, anti-diabetic, and anti-cardiovascular. In our previous study, gas chromatography mass spectroscopy check of CA extract showed the inclusion of 2,4-bis(1,1-dimethylethyl)-phenol, a phenolic phyto-compound that constitutes about 45 %, carotene and linoleic acid sources, and silicon-rich components. Hence we compare the preventive and ameliorative potentials of CA with ascorbate in dimethyl nitrosamine (DMN)-induced renal toxicity and sperm abnormalities in rats.

Cyclophosphamide (CYCP), a synthetic alkylating antineoplastic, disrupts both cancerous and non-cancerous cells to cause cancer regression and multi organotoxicity respectively. CYCP-induced hepatotoxicity is rare but possible. Evidence has shown that naringin has several beneficial potentials against oxidative stress, inflammation, and fibrosis.

This present research investigated variations in lipid profiles and important biomarkers of tissue damage in response to graded concentrations of alcohol administration in male Wistar rats. Group A (control) received distilled water while group B, C and D received 30%, 40% and 50% (v/v) alcohol respectively. Five rats each from groups A-D were sacrificed after day(s) 1, 7, 14, 21 and 28 of administration.

To investigate the effects of oral administration of probiotics consortium on lipid metabolism in aflatoxin B1 (AFB1) exposed rats, ninety female albino rats were first grouped into two: NC (control fed standard feed) and AF (fed AFB1-contaminated feed at 40 ppb). After eight weeks, baseline animals were sacrificed from both groups while the others further divided into four groups - NC treated with and without the probiotics consortium, aflatoxin treated with and without the probiotics consortium (NCT, NCC, AFT, and AFC respectively). Five animals from each group were sacrificed weekly for four weeks, with the collection of blood, liver, brain, and the small intestine.
