Article Synopsis
  • Natural polyphenols in health supplements and drinks provide antioxidant and anti-inflammatory benefits, leading to increased consumer interest in accurately measuring their levels in beverages.
  • A new portable detection method using color-changing beads enables simple, quick quantification of polyphenols; users just dip the beads in the sample and take a photo for analysis.
  • This bead-based sensor offers superior detection limits compared to traditional assays and maintains its effectiveness even after long storage or environmental changes.

Phytoremediation of metals from water (WM) and nutrient (NM) media exposed to waste metal cutting fluid (WMCF) along with temperature (T) and humidity (H) stress was tested using Azolla imbricata (Roxb.) Nakai. In the absence of WMCF, biomass was higher in NM than in WM during all tests.

Article Synopsis
  • This study evaluated the effects of metal oxide nanoparticles (CdO-NP and CuO-NP) on the germination and growth of Vigna radiata in soils, with one group tested with sawdust and another without.
  • Findings showed that seed germination was significantly affected by the type of nanoparticles and the presence of sawdust, with better results in sawdust-treated soil.
  • The results suggest that sawdust can reduce the toxic effects of nanoparticles, improve plant growth, and decrease heavy metal accumulation in the plants.

In this study, the concentration of foliar dust and 23 elemental concentrations in foliar dust and foliar tissues were studied using long rows of grand tamarind trees grown in two major roads in Coimbatore, India. Twenty-four sampling sites were chosen and categorized as urban (n = 5), suburban (n = 14), and rural (n = 5) areas based on the local population. In the case of foliar dust concentration, a significant difference was noted between the sites of urban (range between 3.

The steroid hormones act by binding to their receptors and subsequently interacting with coactivators. Several classes of coactivators have been identified and shown to be essential in estradiol (E2) responsiveness. The major coregulators are the p160 steroid receptor coactivator (SRC) family.

Pregnenolone sulfate (PS) is a neuroactive steroid hormone produced in the brain. In this study, the effects of PS on synthesis and secretion of rat pituitary prolactin (PRL) were examined. To accomplish this, GH3 rat pituitary adenoma cells were treated with PS, which showed significantly increased mRNA and protein levels of PRL compared with the control.
