    Jingjing Liao1,2, Jinxing Li2, Hongyan Wang3, Yan Zhu2, Hisham Essawy4, Guanben Du1,2,*, Xiaojian Zhou2,*

    Journal of Renewable Materials, Vol.10, No.1, pp. 19-31, 2022, DOI:10.32604/jrm.2021.016152 - 27 July 2021

    Abstract The current work explores the potential use of commercial Chinese bayberry tannin (BT) to develop antioxidant PVA-based films using solvent casting process for packaging applications. The effect of BT concentration on opacity, water resistance and antioxidant capacity of resulting films was investigated. Properties like tensile strength, thermal behavior, and morphological aspects were also characterized. The experimental results showed that PVA/BT films formed with uniformly brown color and generally good transparency, offering good antioxidant ability. The PVA film containing BT presented slightly higher water resistance according to the results of moisture content and water vapor permeability, More > Graphic Abstract

    ELIF ANT BURSALI1,*, DILER ABACI1, MURAT KIZIL2, MURUVVET YURDAKOC1

    Journal of Polymer Materials, Vol.38, No.3-4, pp. 231-245, 2021, DOI:10.32381/JPM.2021.38.3-4.5

    Abstract Genipin cross-linked/boron doped starch/polyvinily alcohol (PVA) based hydrogel (SH-GNP-B) was synthesized as a new material having antimicrobial and antioxidant activity. The prepared hydrogel was characterized by X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Thermal Gravimetric Analysis (TGA) and Scanning Electron Microscope (SEM) methods and evaluated for in vitro antimicrobial activities against selected organisms by disc diffusion tests. The antioxidant activity of the prepared hydrogels was evaluated using 2,2-diphenyl-1- picrylhydrazyl radical scavenging assays. Swelling behavior of the hydrogel was also investigated. The synthesized hydrogel was thermally stable and showed pH independent swelling tendency. SH-GNP-B hydrogel More >

    Raghav Mishra1,2,*, Nitin Kumar3, Neetu Sachan2

    Oncologie, Vol.23, No.4, pp. 493-514, 2021, DOI:10.32604/oncologie.2021.018532 - 31 December 2021

    Abstract The relevance of Retinoic acid receptor-related orphan receptors in cancer progression has sparked interest in developing multifunctional therapeutics. In the search for potentially active novel compounds with anticancer characteristics, the Gewald reaction was employed to develop different thiophene derivatives (8a–8i). Physicochemical and spectroanalytical investigations verified the molecular structures of the synthesized derivatives. Using an in vitro primary anticancer assay, NCI chose all of the synthesized molecules as prototypes and assessed their anticancer efficacy against a panel of various cancer cell lines representing nine distinct neoplasms. The compounds were found to have a wide range of anticancer… More >

    Oxidative stress indicators in human and bottlenose dolphin leukocytes in response to a pro-inflammatory challenge

    TARYN E. SYMON1, RAMÓN GAXIOLA-ROBLES1,2, CLAUDIA J. HERNÁNDEZ-CAMACHO3, TANIA ZENTENO-SAVÍN1,*

    BIOCELL, Vol.45, No.6, pp. 1621-1630, 2021, DOI:10.32604/biocell.2021.016302 - 01 September 2021

    Abstract Marine mammals undergo cycles of tissue ischemia and reperfusion during the dive response. Reperfusion injury can result in oxidative tissue damage and the activation of a pro-inflammatory immune response. The risk of oxidative damage is reduced by antioxidants. Our hypothesis is that the reported higher antioxidant defenses within marine mammal tissues provide additional protection in situations that produce oxidative stress, like inflammation, in comparison to terrestrial mammal tissues. Leukocytes were isolated from the whole blood of Pacific bottlenose dolphins (Tursiops truncatus gilli) and humans (Homo sapiens) and were exposed to lipopolysaccharides (LPS, 10 µg/mL) in vitro to simulate… More >

    Abstract Diabetes mellitus (DM) could negatively affect patients’ health via inducing a lot of serious functional hazards in many tissues’ cells at molecular levels. Recently, many scientists had proposed stem cell therapy being an appropriate alternative treatment protocol for numerous health threatening issues including diabetes. Therefore, the current study was designed to investigate the antioxidant potentiality of two MSCs types in alleviating tissues’ oxidative stress dramatic elevation resulting as a consequence of Type 1 DM induction. In our 4 weeks study, animals were divided into four groups: control group, STZ-diabetic group (D), D+AD-MSCs group and D+BM-MSCs… More >

    Abstract Soil contamination with toxic heavy metals [such as cadmium (Cd)] is becoming a serious global problem due to rapid development of social economy. Iron (Fe), being an important element, has been found effective in enhancing plant tolerance against biotic and abiotic stresses. The present study investigated the extent to which different levels of Ferrous sulphate (FeSO4) modulated the Cd tolerance of rice (Oryza sativa L.), when maintained in artificially Cd spiked regimes. A pot experiment was conducted under controlled conditions for 146 days, by using natural soil, mixed with different levels of CdCl2 [0 (no Cd), 0.5… More >

    Mengyuan Dong#, Rong Sun#, Qianhui Yang, Lantian Zhang, Yangying Yong, Yunxia Fang, Xian Zhang, Xiaoqin Zhang*, Dawei Xue*

    Phyton-International Journal of Experimental Botany, Vol.90, No.6, pp. 1589-1598, 2021, DOI:10.32604/phyton.2021.017465 - 28 June 2021

    Abstract In recent years, zinc oxide nanoparticles (ZnO NPs) have been widely used as zinc fertilizers and pesticides. The use of ZnO NPs in this way can provide benefits to humans, but also has potential risks. ZnO NPs inevitably enter the environment during their production and use, which affects the ecological environment and crop growth. In order to investigate the phenotype, physiology, and gene expression of barley (Hordeum vulgare L.) seedlings under ZnO NPs stress, the barely cultivars ZJU3 (P21), Golden Promise (GP) and L23 were chosen for study. Different ZnO NPs concentrations were applied to compare… More >

    Yu-Jyun Chen, Xian-Hao Yang, Yun-Yang Chao*

    Phyton-International Journal of Experimental Botany, Vol.90, No.5, pp. 1477-1489, 2021, DOI:10.32604/phyton.2021.015719 - 27 May 2021

    Abstract Nanosilver (10−9 m) refers to particles comprising 20–15,000 silver atoms, exhibiting high stability and specific surface area. At present, nanosilver has been used in agricultural cultivation and production. This study examined the effects of nanosilver on growth and development of rice root systems. Study results showed that fresh weight of rice belowground organs and root length both increased significantly by 5% and 25%, respectively, after rice radicles were treated with 2 ppm of nanosilver for three days. However, the H2O2 level reached its peak at 2 days from treatment, but the activities of the antioxidant enzymes… More >

    Seerat Saleem1, Naveed Ul Mushtaq1, Wasifa Hafiz Shah1, Aadil Rasool1, Khalid Rehman Hakeem2,*, Reiaz Ul Rehman1,*

    Phyton-International Journal of Experimental Botany, Vol.90, No.5, pp. 1363-1385, 2021, DOI:10.32604/phyton.2021.014826 - 27 May 2021

    Abstract Abiotic stresses such as drought, heat, cold, nutrient deficiency, excess salt and hazardous metals can hamper plantgrowth and development. Intensive agriculture of only a few major staple food crops that are sensitive and intolerant to environmental stresses has led to an agrarian crisis. On the other hand, nutritionally rich, gluten free and stress tolerant plants like millets are neglected and underutilized. Millets sustain about one-third of the world’s population and show exceptional tolerance to various abiotic and biotic stresses. Millets are C4 plants that are adapted to marginal and dry lands of arid and semi-arid… More >
