This study tested the anti-hyperlipidemic, hypoglycemic, hepatoprotective, and anti-inflammatory effects of whole pearl millet grain powder (MPG) and its ethanol extract (MPGethaolE) in obese rats fed a high-fat diet. The rats were divided into eight groups based on the treatments they received: control, high fat diet (HFD), HFD + MGE (25 mg/Kg), HFD + MPGethaolE (50 mg/Kg), HFD + MPGethaolE (100 mg/Kg), HFD + MPG (10%), HFD + MPG (20%), and HFD + MPG (30%). The final body weight, visceral, epididymal fat pads, and the liver weight were significantly decreased, in a dose-dependent manner, in HFD fed rats that were co-administered either the MPG powder or MPGethaolE. In the same line, serum levels of triglycerides (TGs), cholesterol (CHOL), and low-density lipoprotein-cholesterol (LDL-c), as well as fasting glucose, insulin, HOMA-IR, and serum levels of lipopolysaccharides (LPS), interleukine-6 (IL-6), interleukine-10 (IL-10), C-reactive protein (CRP), tumor necrosis factor (TNF-α), and adiponectin were progressively decreased while serum levels of high-density lipoproteins (HDL-c) were significantly increased when increasing the doses of both treatments. In conclusion, both the raw powder and ethanolic extract of MP have a comparative dose-dependent anti-obesity, hypoglycemic, hypolipidemic, anti-inflammatory, and anti-steatotic in HFD-fed rats.

An unavoidable consequence of aerobic respiration is the generation of reactive oxygen species (ROS). ROS is a collective term that includes both oxygen radicals and certain oxidizing agents that are easily converted into radicals. They can be produced from both endogenous and exogenous substances. ROS play a dual role in biological systems, since they can be either harmful or beneficial to living systems. They can be considered a double-edged sword: oxygen-dependent reactions and aerobic respiration have significant advantages but overproduction of ROS, a consequence of oxygen-dependent reactions, has the potential to cause damage. Overproduction of ROS may negatively impact neonatal growth and contribute to the aetiology of many developmental disorders. During mitochondrial respiration, an inability to neutralize reactive oxygen species and free radicals leads to oxidative stress. The inner membrane of the mitochondria contains a large number of free radical scavengers including glutathione, vitamin C, and vitamin E, as well as anti-oxidant enzymes such as superoxide dismutase. The brain is particularly vulnerable to free radical attack for several reasons, including exposed to high oxygen concentrations, relatively low antioxidant protection, membranes with high levels of polyunsaturated fatty acids, and high iron and ascorbate content. The brain's high energy demand is primarily supplied by oxidative phosphorylation, the major producer of free radicals. When the level of free radicals overwhelms the cellular antioxidant defense system, a deleterious condition known as oxidative stress occurs. ROS has an intimate relationship with mitochondrial function and oxidative stress is believed to result from mitochondrial dysfunction. This review highlights the role of oxidative stress and mitochondrial dysfunction as key players in the neurodevelopmental pathophysiology. The mechanisms associating these two disease states can lead to neuronal death, neuroinflammation and impairment of energy metabolism. Biomarkers related to both aspects will be highlighted to demonstrate their importance in the early diagnosis of neurodevelopmental disorders like autism, cerebral palsy and others. Treatments trials for oxidative stress or mitochondrial dysfunction using nutritional supplements and antioxidants are reviewed in order to shed light on recent strategies for the early intervention for neurodevelopmental disorders.

Background:Obesity is a risk factor for several diseases related to oxidative stress, hyperlipidemia, and hyperglycemia. Several pharmacological agents have been used to treat obesity, but these commonly exhibit undesirable side effects. The aim of this study was to explore the effects of Garcinia mangostana (mangosteen) and Curcuma longa independently and synergistically in modulating selected biochemical markers of oxidative stress, dyslipidemia, and hyperglycemia commonly observed in high-fat diet-induced obesity in rodent models. Methods:Male albino Wistar rats were divided into eight experimental groups, fed on a normal diet or high-fat diet (HFD), then given mangosteen extract (400 mg /kg body weight/day) and/or curcumin (80 mg/kg body weight/day) for 6 weeks. Oxidative stress markers, glucose, and lipid fractions were measured in the sera. Results:Curcumin was found to be more effective in reducing BMI, while mangosteen extract was found to induce a significant increase in anti-atherogenic marker HDL-C, but was ineffective in reducing dyslipidemia. Mangosteen extract and curcumin effectively reduced blood glucose. Mangosteen did not exhibit any anti-oxidative effects in normal weight rats; however, it induced a significant increase in glutathione in obese rats. Conclusion:The present study demonstrated that mangosteen pericarp extract and curcumin were independently and synergistically effective in treating obesity-induced atherogenesis.

A substantial interest has been manifested in utilizing oil/metal oxide hybrid bionanocomposite, especially organic/ inorganic to design different biomedical applications. The present study reports the synthesis, characterization, antibacterial and anticancer properties of biogenic silver nanoparticles (AgNPs) and L.satiVum oil/PEG/Ag-MgO bionanocomposite. The fabricated AgNPs and L.sativum oil/PEG/Ag-MgO bionanocomposite were characterized by employing different spectroscopic (UV, FTIR, XRD) and microscopic (TEM, SEM) techniques. The particle size analysis showed that the mean size of 16.32 nm for AgNPS and 13.45 nm L.satiVum oil/PEG/Ag-MgO, indicating the excellent dispersion of Ag-MgO nanoparticles in the PEG– L.satiVum oil matrix. The antimicrobial activity of AgNPs and polymeric bionanocomposite was investigated against two pathogenic bacteria. The highest antibacterial effect was observed for bionanocomposite towards Gram-positive Staphylococcus aureus (27 mm) and Gram-negative Escherichia coli (25 mm) at 40 µg/well. The bionanocomposite completely vanished the bacterial growth (100%) at 80 µgmL −1 concentrations. Moreover, the AgNPs and polymeric bionanocomposite was evaluated for anticancer activity against human cervical cancer cells (HeLa cells) at different doses (50, 250, 500, and 1000 µgmL −1 ). The results showed polymeric bionanocomposite was stronger in inducing the HeLa cancer cell death than AgNPs. Overall, the fabricated L.satiVum oil/PEG/Ag-MgO bionanocomposite serve as a potential antimicrobial and anticancer agent and could be used in the development of novel drugs and health care products in near future.
