    Abstract Over the past few decades, nanotechnology has shown promising prospects in biomedicine and has a proven impact on enhancing therapeutics by facilitating drug delivery. The present study brings an amalgamation of nanoscience and “clean technology” by fabricating nature-friendly nanoparticles (NPs) sans the use of chemical surfactants using Indian mustard seed, Brassica juncea L. The as-synthesized NPs were characterized to assess their average size, crystallinity, morphology, and constituent functional groups through conventional techniques: dynamic light scattering (DLS), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR). The NPs were crystalline in nature and exhibited a mean size of 205.5 nm (PDI of 0.437) being primarily polygonal in shape. Additionally, the therapeutic efficacy of the green NPs was evaluated based on their cytotoxic effect against two human cancer lines, MCF-7 and HepG-2. Both the NPs and the bulk seeds showed a dose-dependent cytotoxic effect. However, an assessment of the antiproliferative/cytotoxic potential of the green NPs versus the bulk seeds showed that the NPs were relatively more efficacious on both cell lines. Taken together, the mustard seed NPs could be potential nutraceuticals considering the green credential in their mode of biosynthesis.

    Abstract Contamination of cereal crops with zearalenone (ZEA), a mycotoxin produced by Fusarium fungi, is a worldwide health concern. The study assessed the ameliorative potential of resveratrol (RSV), a potent antioxidant against ZEA induced toxicity in adult male Wistar rats. Rats (n = 40), with an average weight of 100-150 g were used for the exposure study for three weeks. The animals were divided into four groups (I to IV) each comprising 10 rats. Group I was kept as negative control and was administered normal saline. Group II and III were exposed to 2 mg/kg of the mycotoxin, ZEA administered intraperitoneally once every week. Group III was treated with resveratrol (RSV) orally (5 mg/kg) daily. Group IV was treated only with resveratrol (5 mg/kg/daily) as a positive control. The protective effect of resveratrol was evaluated on; biochemical variables, biomarkers of oxidative stress, markers of immunotoxicity, and DNA damage. The findings showed that exposure to ZEA elicited oxidative stress and modulated the antioxidant enzyme activities. A disarray in the lipid profile, parameters of the humoral and cellular immune response; serum cytokines and immunoglobulins was also observed. Further, COMET assay showed detectable DNA lesions. Taken together, RSV was efficacious in reducing and/or reversing the ZEA induced toxicity.

    Abstract The aim of the present study was a qualitative assessment of potential microplastics (MPs) in the sewage effluent collected from a local sewage treatment plant located in Riyadh City, Saudi Arabia. The composite samples of domestic sewage effluent were subjected to UV (ultraviolet) light-induced zinc oxide nanoparticles (ZnONPs) mediated photocatalysis. The first phase of the study included the synthesis of the ZnONPs with an extensive characterization. The synthesized nanoparticles were 220 nm in size with a characteristic spherical/hexagonal shape. These NPs were then used at three different concentrations (10 mM, 20 mM, and 30 mM) for the UV light-induced photocatalysis. A shift in the Raman spectra on photodegradation mirrored the surface changes of the functional groups shown by the FTIR spectra; presence of functional groups containing oxygen and C-C bonds associated with oxidation and chain scission. SEM micrographs showed photodegraded particles. Complementary elemental maps from the EDS analysis showed the presence of C, O, and Cl suggesting the potential presence of MPs. The O/C ratio was used to assess potential oxidation degree. In addition, an evaluation of the toxicological effects of the potential MPs in the sewage effluent on Nile tilapia (Oreochromis niloticus) exposed to the effluent at two concentrations (50% and 75%) elicited a marked response in the endpoints evaluated; EROD activity, MDA (malondialdehyde), 8-oxo-2'-deoxyguanosine levels in and AChE (acetylcholinesterase) activity in the brain. Thus, the key results provide new insights into the use of clean technologies to combat global MP pollution in aquatic ecosystems.

    Abstract The study assessed the antidiabetic effect of Solenostemma argel and its nanoformulations with silver/gold nanocomposites (CNPs), zinc oxide nanoparticles (ZnONPs), and metaformin drug. Experimental groups consisted of normal control, diabetic control, and four diabetic groups treated with metformin, CNPs, ZnONPs, and bulk argel leaf extract (So-argel). Transmission electron microscopy characterization showed that the synthesized CNPs and ZnONPs were of variable sizes and dimensions and were quasi-spherical in shape. Particle sizes measured by dynamic light scattering were 106 and 139 nm for CNPs and ZnONPs, respectively. Also, the polydispersity index values were 0.473 and 0.269 for CNPs and ZnONPs, respectively. The biochemical parameters were as follows: the group treated with bulk So-argel (105.00 ± 4.041 mg·dL−1) and CNPs (109.00 ± 8.373 mg·dL−1) showed a more profound anti-hyperglycemic effect and were comparable to the control (88.40 ± 2.249). Liver and kidney functions (p ≤ 0.05) improved with So-argel and its nanoformulations compared to metformin. However, bulk argel (170.33 ± 20.431 and 38.00 ± 3.05 U·L−1) and the nanocomposite (228.33 ± 11.464 and 48.00 ± 5.291 U·L−1) were efficacious in lowering serum levels of liver enzymes (AST and ALT, respectively). No significant difference was observed between urea levels. Nevertheless, bulk So-argel (0.26 ± 0.007) and CNPs (0.24 ± 0.018) were more effective than ZnONPs (0.41 ± 0.289) on serum creatinine. Nanotreatment exhibited a reduction in lesions size/healing. Overall, nanoparticles may offer a safe potential for Type 2 diabetes management.

    Abstract The present study investigates the protective efficacy of stem bromelain against lead-induced toxicity in male Wistar rats. There were six experimental groups; Group I was negative control, Group II was administered only 20 mg/kg of stem bromelain. Group III and V were orally exposed to 30 mg/kg/day and 60 mg/kg/day of lead acetate, respectively. Group IV and Group VI were exposed to both low and high dose of lead acetate, respectively, and treated with 20 mg/kg stem bromelain. The experimental period was 21 days. The end points evaluated were, lead accumulation in kidney, liver and spleen, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity, serum malonaldehyde (MDA) cholesterol and triglycerides levels. Co-administration of stem bromelain with lead markedly reduced the lead accumulation in the kidney and spleen. The treatment of stem bromelain also reduced the serum MDA levels in the group exposed to lower dose of lead and serum triglyceride level in the group exposed to higher dose of lead. The lead-induced modulated levels of serum ALT and AST were also alleviated by bromelain treatment. Our key findings suggest a chelating potential of stem bromelain for combating lead toxicity and oxidative stress. Bromelain represents a novel approach to the treatment of metal toxicity and metabolic disorders with a limited therapeutic window.

    Abstract The study investigated the effect of calcium (Ca) supplementation on lead-induced toxicity in suckling male Wistar rats. The sucklings were exposed to lead acetate (5 mg/kg b wt./week) orally for a period of six weeks. The unexposed group of sucklings was the negative control. Out of the lead-exposed groups, two groups were supplemented with Ca at 3% and 6% as CaHPO ₄ × 2H ₂O in suspension in cow's milk. The artificial feeding regimen was followed for 7 h each day for 6 weeks. Sucklings exposed to lead with Ca supplementation recorded a significantly higher increase in body weight and a significant reduction of lead concentration in all tissues. The lead-induced histopathological alterations in the liver and kidney were also reversed with Ca supplementation. Sodium rhodizonate staining of liver sections showed distinct presence of lead granules in the group exposed to lead while the Ca-supplemented groups were comparable to the control. Lead exposure reduced the expression of rad 51 in the testis and liver which was markedly enhanced with Ca supplementation and was restored to the level in the control. Thus, Ca supplementation during the suckling period was effective in ameliorating the lead-induced toxicity.

    Abstract The present studywas undertaken to assess the bioaccumulation potential of cadmium in liver, kidney, gills and muscles of freshwater fish, Nile tilapia Oreochromis niloticus and the changes in oxidative stress indices in liver and kidney with or without simultaneous treatment with waterborne vitamin C and rosemary leaf extract. Adult tilapia were divided into seven groups. Six groups were exposed to sublethal concentrations of Cd, three groups to 5 ppm, while other three to 10 ppm. Two groups from each of the Cd exposed groups were treated with Vitamin C (5ppm) and rosemary leaf extract (2.5 ppm) for a period of 21 days. Cadmium concentration in liver, kidneys and gills was significantly higher in the cadmium exposed groups being invariably high in the groups exposed to 10 ppm CdCl2.H2O.Treatment with Vitamin C and rosemary leaf extract significantly reduced cadmium concentration in comparison to non-treated Cd exposed groups. Treatment with Vitamin C and rosemary leaf extract significantly reduced oxidative stress in Cd exposed fish as evidenced from lower concentration of lipid peroxides and reduced activity of catalase and higher activity of superoxide dismutase in liver and kidney as compared to control fish. Reduction in Cd induced oxidative stress and bioaccumulation was comparable between the two antioxidant treatments, Vitamin C and rosemary leaf extract. The key findings suggest that both the antioxidants used showed ameliorative potential to reduce tissue accumulation of Cd and associated oxidative stress in fresh water fish, Nile tilapia.
