TL;DR: The decrease of antioxidant enzymes due to cadmium exposure was reversed significantly with herbal extract administration and the synergistic effect of each bioactive compound in different herbal extracts requires further study.
Abstract: Cadmium is one of the elements found to damage antioxidant systems in mammals. To ameliorate cadmium toxicity and to prevent oxidative stress, natural products may be useful. In Indian ethnobotanical practice, a mixture of 17 herbal products is used to fortify the reproductive system of women after parturition and to reverse ovarian oxidative stress. Oral administration of this extract to rats exposed to cadmium was useful in reversing oxidative stress. Two different doses of cadmium (50 ppm and 200 ppm) were given to Wistar rats aged 45 and 65 days. An herbal extract derived from 17 plants was administered orally every day at a dose level of 200 mg/kg of body weight to the rats exposed to cadmium. A battery of enzymes involved in antioxidant activity in the ovary, including superoxide dismutase (SOD), catalase, glutathione peroxidase (GPx) and glutathione-s-transferase (GST) were measured in the control, cadmium-exposed rats without treatment and in the cadmium-exposed rats treated with herbal extract. The reduction in SOD, catalase, GPx and GST activity after cadmium exposure improved significantly in the rats treated with the herbal extract (p < 0.05). The decrease of antioxidant enzymes due to cadmium exposure was reversed significantly with herbal extract administration. The synergistic effect of each bioactive compound in different herbal extracts requires further study.

TL;DR: In this paper, bio-augmented silver nanoparticles with Derris trifoliata seed extract (AgNP-DT) have been developed for the reduction of a water soluble azo dye-methyl orange.
Abstract: In the present study, bio-augmented silver nanoparticles with Derris trifoliata seed extract (AgNP-DT) have been developed. Formation of AgNP-DT has been confirmed with X-ray diffraction (XRD), High resolution transmission electron microscopy (HRTEM) and Fourier-transform infrared spectroscopy (FTIR). Even though introduced for the first time as a catalyst owing to high surface area, the as-prepared nanoparticles showed one of the best catalytic activity in the reduction of a water soluble azo dye–methyl orange. An incredible pseudo-first order rate constant (0.3208 min−1) and activity parameter (1086 s−1 g−1) were obtained for the catalytic reduction of methyl orange with 4.9 μg AgNP-DT. Furthermore, AgNP-DT exhibits a good selectivity and sensitivity towards mercury(II) ions over other metals in aqueous solution. Absorbance of AgNP-DT exhibits a good linear relationship against concentration of Hg2+ with a limit of detection (LOD) of 1.55 μM. The mechanism of sensing activity of AgNP-DT was elucidated by measuring the variation in the zeta potential of the system with increasing concentration of Hg2+. Moreover the proposed method could be practicably applied for the detection of Hg2+ in real water samples with a percentage recovery in range of 91.41–108.07%.

TL;DR: In this article, pristine ZrO2 and Mg (0.02, 0.08) nanoparticles were synthesized at about 10nm size and achieved complete degradation of methyl violet and methyl blue dyes under UV irradiation.
Abstract: In this study, pristine ZrO2 (600 °C) and Mg (0.02, 0.04, 0.06, 0.08 M)-doped ZrO2 nanoparticles were effectively synthesized at about 10 nm size and achieved complete degradation of methyl violet and methyl blue dyes under UV irradiation. The calcined products were analyzed by XRD, FTIR, UV-DRS, PL, FESEM-EDX, TEM-SAED pattern and XPS techniques. The tetragonal crystal structure of the pristine ZrO2 and Mg (0.02–0.08 M)-doped ZrO2 nanoparticles were affirmed by XRD analysis. The Mg (0.08 M)-doped ZrO2 nanoparticles were approximately in quasi-spherical morphology and high agglomeration was confirmed by FESEM and TEM results. The surface defects and oxygen vacancies were analyzed by PL spectroscopy. The Mg (0.08 M)-doped ZrO2 nanoparticles exhibited enlarged photocatalytic activity with 94% and 90% degradation of methyl violet and methyl blue dyes under UV irradiation.
