The Nephroprotective Potential of Brassica nigra Sprout Hydroalcoholic Extract against Carbon Tetrachloride-Induced Renal Toxicity in Rats

The nephroprotective potential of the Brassica nigra sprout (BNS) hydroalcoholic extract against carbon tetrachloride (CCl4)-induced renal toxicity in rats was the object of this study. B. nigra sprouts were prepared in the lab to monitor the bio-changes in bioactive compounds during the sprouting for up to 7 days at 17 ± 1 °C and 90% relative humidity. Subsequently, 6-day sprouts of B. nigra were selected according to their phenolics and antioxidant activity, extracted, and examined for their nephroprotective and antioxidative stress potential at 250 and 500 mg sprout extracts kg-1 bw, in vivo. Weight gain, organ weight, lipid profile, atherogenic index, kidney functions, and oxidative stress biomarkers were assessed. The results indicated that the most proficient treatment for weight gain improvement was BNS extract at 500 mg kg-1. BNS at 250 mg kg-1 was remarked as the lowest weight gain enhancer compared to the NR group. A significant increase in TG, TC, LDL-c, and VLDL-c levels in the rats with CCl4-induced renal toxicity, and a significant decrease in HDL level, was noted. The administration of the BNS extract at 250 and 500 mg kg-1 considerably attenuated TG, TC, LDL-c, and VLDL-c levels, compared to the NR group. The most efficient treatment for improving the lipid profile was the BNS extract at 500 mg kg-1, even better than 250 mg kg-1. Administrating the BNS extract substantially attenuated the alterations in the creatinine, urea, and BUN caused by the CCl4 injection. The most efficient improvement was markedly recorded with the BNS extract at 500 mg kg-1, compared to the NR group. The rats treated with the BNS extract showed significant enhancement in GSH, CAT, and SOD activities and a considerable reduction in MDA levels. Administering the BNS extract at 250 and 500 mg kg-1 can efficiently reverse CCl4 inhibition of antioxidant enzyme activities, significantly increase GSH, CAT, and SOD, and decrease the MDA levels dose-dependently. The BNS extract at 250 and 500 mg kg-1 exhibits nephroprotection and antioxidative stress in a dose-dependent matter. The total nephroprotection % was recorded at 65.18% and 99.21% for rats treated with 250 and 500 mg kg-1, respectively. These findings could prove and potentiate the nephroprotective activities of the BNS extract in the range of the given doses. Further clinical studies are highly recommended for confirming the nephroprotection efficiency of the B. nigra sprout.

Natural anti-aging skincare: role and potential

The deterioration of the skin morphology and physiology is the first and earliest obvious harbinger of the aging process which is progressively manifested with increasing age. Such deterioration affects the vital functions of the skin such as homeodynamic regulation of body temperature, fluid balance, loss of electrolytes and proteins, production of vitamin D, waste removal, immune surveillance, sensory perception, and protection of other organs against deleterious environmental factors. There are, however, harmful chemicals and toxins found in everyday cosmetics that consumers are now aware of. Thus, the natural beauty industry is on the rise with innovative technology and high-performance ingredients as more consumers demand healthier options. Therefore, the aims of this review are to give some critical insights to the effects of both intrinsic and extrinsic factors on excessive or premature skin aging and to elaborate on the relevance of natural beauty and natural anti-aging skincare approaches that will help consumers, scientists and entrepreneurs make the switch. Our recent investigations have shown the potential and relevance of identifying more resources from our rich natural heritage from various plant sources such as leaves, fruits, pomace, seeds, flowers, twigs and so on which can be explored for natural anti-aging skincare product formulations. These trending narratives have started to gain traction among researchers and consumers owing to the sustainability concern and impact of synthetic ingredients on human health and the environment. The natural anti-aging ingredients, which basically follow hormetic pathways, are potentially useful as moisturizing agents; barrier repair agents; antioxidants, vitamins, hydroxy acids, skin lightening agents, anti-inflammatory ingredients, and sunblock ingredients.
