Aflatoxin B1-induced redox imbalance in the hippocampus and cerebral cortex of male Wistar rats is accompanied by altered cholinergic, indoleaminergic, and purinergic pathways: Abatement by dietary rutin.

The neurotoxic impact of dietary exposure to aflatoxin B1 (AFB1) is well documented in experimental studies. Rutin is a phytochemical with prominent anti-inflammatory and antioxidant activities. There is an information gap on the influence of rutin on AFB1-induced neurotoxicity.

Zinc Ameliorates Cadmium-Induced Immunotoxicity by Modulating Splenic Immunosuppressive Indoleamine 2,3-Dioxygenase Activity, Hematological Indices, and CD4 T Cells via Inhibition of Cadmium Uptake in Male Wistar Rats.

Cadmium (Cd)-induced immunotoxicity has become a matter of public health concern owing to its prevalence in the environment consequently, great potential for human exposure. Zinc (Zn) has been known to possess antioxidant, anti-inflammatory, and immune-boosting properties. However, the ameliorating influence of Zn against Cd-induced immunotoxicity connecting the IDO pathway is lacking.

The antioxidant/anti-inflammatory protective effects of rutin against ethanol-induced testicular perturbation in rats: Involvement of the immunosuppressive indoleamine 2,3-dioxygenase.

This study investigated the influence of rutin against EtOH-induced testicular impairment in rats and the involvement of the indole-aminergic pathway. Four groups of eight rats each were orally exposed to drinking water (Group 1), EtOH (5 g/kg bwt, Group 2), R (5 g/kg bwt, Group 3), and EtOH + R (5 g/kg bwt + 50 mg/kg bwt, Group 4) via gavage for 15 days. Results showed that exposure to EtOH significantly (p < 0.

Rutin co-treatment prevented cognitive impairment/depression-like behavior and decreased IDO activation following 35 days of ethanol administration in male Wistar rats.

Alcohol (ethanol) is among the most popularly consumed beverages globally. Ethanol was earlier demonstrated to elicit cognitive impairment and depressive-like effects in both human and animal studies. Rutin (R) is known for its antioxidant, anti-inflammatory, immunomodulatory, and anti-depressive properties, among others.

Abatement of cyclophosphamide-induced splenic immunosuppressive indoleamine 2, 3-dioxygenase and altered hematological indices in Wister rats by dietary quercetin.

The immunotoxicity mediated by cyclophosphamide (CYP) was earlier reported. Quercetin, due to its anti-oxidative/inflammatory properties elicits a plethora of health benefits. However, the influence of quercetin on the splenic/immunotoxicity linked with CYP-induced indoleamine 2,3-dioxygenase (IDO) is unavailable in the literature.

Cyclophosphamide-induced testicular oxidative-inflammatory injury is accompanied by altered immunosuppressive indoleamine 2, 3-dioxygenase in Wister rats: Influence of dietary quercetin.

This study evaluated the role of quercetin against cyclophosphamide-induced distortion of rat testicular function. Adult rats were administered cyclophosphamide (100 mg/kg), quercetin (50 mg/kg) and in combination for seven days. Cyclophosphamide caused a significant increase in the activities of indoleamine 2, 3-dioxygenases (IDO), tryptophan 2, 3-dioxygenase (TDO), myeloperoxidase (MPO), and elevated the concentrations of interleukin 6 (IL-6) and interferon-γ (IFN-γ).

Cyclophosphamide instigated hepatic-renal oxidative/inflammatory stress aggravates immunosuppressive indoleamine 2,3-dioxygenase in male rats: Abatement by quercetin.

The hepatic-renal toxicity associated with cyclophosphamide (CYP) treatment in both animals and humans have been reported. Quercetin, a dietary flavonoid, is known to elicit beneficial health effects. However, the influence of quercetin on the hepatic-renal toxicity associated with CYP-instigated indoleamine 2,3-dioxygenase is unavailable in the literature.

Salinomycin promotes T-cell proliferation by inhibiting the expression and enzymatic activity of immunosuppressive indoleamine-2,3-dioxygenase in human breast cancer cells.

Indoleamine 2,3 dioxygenase (IDO) is upregulated in many tumor types, including breast cancer, and plays a reputable role in promoting tumor immune tolerance. The importance of the immunosuppressive mechanism of IDO by suppressing T-cell function has garnered profound interest in the development of clinical IDO inhibitors. Herein, we established a screening method with cervical HeLa cells to induce IDO expression using interferon-γ (IFN-γ).

Loranthus micranthus nanoparticles abates streptozotocin-instigated testicular dysfunction in Wistar rats: Involvement of glucose metabolism enzymes, oxido-inflammatory stress, steroidogenic enzymes/protein and Nrf2 pathway.

Loranthus micranthus (African mistletoe)-Loranthaceae family, is used in Nigerian traditional medicine for treating male infertility and lowering diabetic blood sugar levels. We investigated possible mechanism(s) involved in mitigation of L. micranthus leaves nanoparticles (LMLNPs) on streptozotocin (STZ)-induced testicular alterations.

Antimicrobial and Wound Healing Properties of Polyacrylonitrile-Moringa Extract Nanofibers.

A simple and cost-effective material composed of polyacrylonitrile nanofibers containing different concentrations of moringa (MR) leaf extracts was fabricated for antimicrobial properties and wound dressing. The fabricated materials were characterized by scanning electron microscopy, thermal gravimetric analysis, and Fourier transmission infrared spectroscopy. The antibacterial sensitivity of the developed polyacrylonitrile-moringa extract nanofibers was evaluated against and by the agar diffusion method.

Natural Nanoparticles: A Particular Matter Inspired by Nature.

During the last couple of decades, the rapidly advancing field of nanotechnology has produced a wide palette of nanomaterials, most of which are considered as "synthetic" and, among the wider public, are often met with a certain suspicion. Despite the technological sophistication behind many of these materials, "nano" does not always equate with "artificial". Indeed, nature itself is an excellent nanotechnologist.

Transient effect of single dose exposure of Nigerian Bonny-light crude oil on testicular steroidogenesis in Wistar rats is accompanied by oxidative stress.

The folkloric use of Nigerian Bonny-light crude oil (BLCO) in Niger Delta area of Nigeria is a common practice. There is increasing experimental evidence portending the adverse effects of BLCO an environmental toxicant on testicular function. We investigated the effects of single dose of BLCO (800 mg/kg body weight) on the activities of steroidogenic and antioxidant enzymes such as serum follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone, 3 β-hydroxy-steroid dehydrogenase (3 β-HSD), 17 β-hydroxy-steroid dehydrogenase (17 β-HSD), superoxide dismutase (SOD), glutathione-S-transferase (GST) and glutathione peroxidase (GSH-Px), levels of lipid peroxidation (LPO), glutathione reduced (GSH) and steroidogenic acute regulatory (StAR) protein, in testes of rats.
