Ethanolic extract of Polygala senega (EEPS) had little or no cytotoxic effects on normal lung cells, but caused cell death and apoptosis to lung cancer cell line A549. In the present paper, ethanolic root extract of P. senega (EEPS) was nanoencapsulated (size: 147.7 nm) by deploying a biodegradable poly-(lactic-co-glycolic) acid (PLGA). The small size of the NEEPS resulted in an enhanced cellular entry and greater bioavailability. The growth of cancer cells was inhibited better by NEEPS than EEPS. Both EEPS and NEEPS induced apoptosis of A549 cells, which was associated with decreased expression of survivin, PCNA mRNA, and increased expression of caspase-3, p53 mRNAs of A549 cells. The results show that the anticancer potential of the formulation of EEPS-loaded PLGA nanoparticles was more effective than EEPS per se, probably due to more aqueous dispersion after nanoencapsulation. Therefore, nanoencapsulated ethanolic root extract of P. senega may serve as a potential chemopreventive agent against lung cancer.

The alga contains salt and heavy metals that are accumulated in algae poses a significant challenge to the safe use of algae in soil fertilization and other applications. This study examines the relevance of algal biomass as an environmentally friendly fertilizer, thereby contributing to sustainable coastal management practices. In this study, the hot and cold extraction method were done to obtain the Ulva rigida extract.

To enhance the measurement speed and improve the adaptability to large curvature measured specular surfaces, this paper proposes a phase measurement deflectometry (PMD) technique based on composite circular fringes. The composite circular fringes demonstrate a steeper slope in the phase change, enabling the acquisition of finer surface features under identical measurement conditions, effectively improving the detection sensitivity to small shape changes and enhancing the ability to discern fine details.

Background: The smear layer formed during root canal instrumentation negatively affects root canal irrigation activity, which in turn can affect the treatment prognosis of endodontic treatment.
Aim: The aim of this study is to compare the efficiency of smear layer and debris removal in root canals using different irrigation protocols using scanning electron microscopy (SEM).
Materials And Methods: The quality of smear layer removal throughout the root canal was assessed in 30 intact extracted teeth divided into 3 groups according to the irrigation protocol: Group 1: 3% sodium hypochlorite (NaOCL) alternately with 17% ethylenediaminetetraacetic acetate (EDTA) was used.

An efficient in vitro propagation protocol has been established for a valuable medicinal plant, Salix tetrasperma using mature nodal explants. The investigation aimed to observe the influence of various combinations and concentrations of cytokinins (mT, BA, and Kn) and auxins (NAA, IAA, and IBA) on regeneration potential using the Murashige and Skoog (MS) medium. Among individual cytokinin treatments, 5.
