A homogeneous polysaccharide (FP2) with 83.3 kDa molecular weight was obtained from the aerial parts of Ficus pandurata H. (Moraceae) by Sevag, anion-exchange chromatography and gel-filtration chromatography. On the basis of composition analysis, infrared spectra (IR) and nuclear magnetic resonance (NMR) experiments, FP2 is a linear pectin with a main chain composed of →4)-α-D-GalpA-(1→. We investigated the anti-proliferative activity and its underlying mechanism of FP2 in HeLa cancer cells, using MTT assay and western blot analysis, respectively. Treatment with FP2 in HeLa cancer cells showed anti-proliferation effect and up-regulated the expression levels of caspase-3 and cleaved-PARP. IC50 values were 31.50 and 22.62 μg/ml for 24 h and 48 h, respectively. FP2 has potential of antitumor possibly due to apoptosis induction mediated through caspase-3 activation and cleavage of PARP. The results suggest that FP2 may be a promising plant polysaccharide targeting for anticancer therapy through activating the apoptotic pathway. V.New advances in molecular approaches for DNA analysis have enhanced our understanding of the phylogenetic relationship of birds. The Little Owl (Athene noctua) is of great significance for the integrated management of forest diseases and control of regional pests. Here, we sequenced and annotated the 17,772 bp complete mitogenome of A. noctua. The mitogenome encoded 37 typical mitochondrial genes 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA, and one non-coding control region (D-loop). The organization and location of genes in the A. noctua mitogenome were consistent with those reported for other Strigidae birds. Phylogenetic relationships based on Bayesian inference and Maximum likelihood methods showed that A. noctua has close relationships with Athene brama and Glaucidium cuculoides, confirming that A. noctua belongs to the Strigidae family. The phylogenetic relationships among seven genera of the Strigidae family used in this study were Ninox and the other six genera were far apart, Otus and the clade ((Bubo + Strix) + Asio) were clustered into one branch, and Athene and Glaucidium were clustered into one branch. This phylogenetic classification is consistent with prior taxonomic studies on the Strigidae family. Our results provide new mitogenomic data to support further phylogenetic and taxonomic studies of Strigidae. Encapsulation technology, as a promising approach, has been employed for the protection and controlled release of different bioactive compounds including natural antioxidants; there are restrictions for applying these valuable ingredients in real food products, pharmaceuticals, and cosmetics such as low solubility, low shelf life, difficultly in their packaging and handling, losses due to environmental stresses and food processes, undesirable flavors and odors, untargeted release and instability in various conditions during digestion in gastrointestinal tract. KPT 9274 inhibitor Nanocarriers can be employed to overcome these challenges. There are five groups of nanocarriers based on the principal mechanism/ingredient used to make them for the encapsulation of natural antioxidants titled biopolymeric nanoparticles, lipid-based and surfactant-based nanocarriers, nanocarriers made with specially designed equipment, nature-inspired nanocarriers, and miscellaneous ones. The main goal of this study is to have an overview of role of different nanocarriers in improving the efficiency of natural antioxidant compounds for different purposes. It has been verified that antioxidant-loaded nanocarriers can be applied in many formulations with a higher and controlled release antioxidant activity, which would meet the current needs of consumers' expectations towards clean label products. Emerging research reinforces the importance of partner accommodation in the interpersonal context of posttraumatic stress disorder (PTSD). A better u
