    Abstract As a natural analog of resveratrol, piceatannol (Pic) exhibits good antioxidant and anti-inflammatory activities in different disease models. However, the role of Pic in type 1 diabetes mouse model has not been reported yet. In this study, we investigated the in vivo effect of Pic in streptozotocin (STZ)-induced type 1 diabetic mice. Mice were injected with STZ to establish the type 1 diabetes mellitus (T1DM) model. After stable hyperglycemia was achieved, mice were then orally treated with Pic (40 mg/kg b.w., i.g.) for 30 days. The results indicated that Pic supplementation efficiently alleviated the typical symptoms associated with T1DM, including… More >

    Md. Shakhawat Hossain1, Md. Daud Hossain1, Abdul Hannan2, Mirza Hasanuzzaman3, Md. Motiar Rohman4,*

    Phyton-International Journal of Experimental Botany, Vol.89, No.3, pp. 541-559, 2020, DOI:10.32604/phyton.2020.010279

    Abstract Salinity stress is a major factor limiting plant growth and productivity of many crops including oilseed. The present study investigated the identification of salt tolerant mustard genotypes and better understanding the mechanism of salinity tolerance. Salt stresses significantly reduced relative water content (RWC), chlorophyll (Chl) content, K+ and K+ /Na+ ratio, photosynthetic rate (PN), transpiration rate (Tr), stomatal conductance (gs), intercellular CO2 concentration (Ci) and increased the levels of proline (Pro) and lipid peroxidation (MDA) contents, Na+ , superoxide (O2•− ) and hydrogen peroxide (H2O2) in both tolerant and sensitive mustard genotypes. The tolerant genotypes maintained higher Pro and lower… More >

    Phyton-International Journal of Experimental Botany, Vol.89, No.3, pp. 497-517, 2020, DOI:10.32604/phyton.2020.09144

    Abstract The research was conducted to investigate comparative oxidative damage including probable protective roles of antioxidant and glyoxalase systems in rice (Oryza sativa L.) seedlings under salinity stress. Seedlings of two rice genotypes: Pokkali (tolerant) and BRRI dhan28 (sensitive) were subjected to 8 dSm−1 salinity stress for seven days in a hydroponic system. We observed significant variation between Pokkali and BRRI dhan28 in phenotypic, biochemical and molecular level under salinity stress. Carotenoid content, ion homeostasis, antioxidant enzymes, ascorbate and glutathione redox system and proline accumulation may help Pokkali to develop defense system during salinity stress. However, the activity antioxidant enzymes particularly… More >

    Aortic stenting in the growing sheep causes aortic endothelial dysfunction but not hypertension: Clinical implications for coarctation repair

    Nicola Maschietto1, Luca Semplicini2, Giulio Ceolotto2, Arianna Cattelan2, Helen Poser3, Ilaria Iacopetti3, Gabriele Gerardi3, Giulia Maria De Benedictis3, Tommaso Pilla3, Daniele Bernardini3, Luca Aresu4, Stefania Rizzo5, Cristina Basso5, Andrea Semplicini2, Ornella Milanesi1

    Congenital Heart Disease, Vol.12, No.1, pp. 74-83, 2017

    Abstract Background: Stent implantation is the treatment of choice for adolescents and adults with aortic coarctation (CoAo). Despite excellent short-term results, 20%–40% of the patients develop arterial hypertension later in life, which was attributed to inappropriate response of the aortic baroreceptors to increased stiffness of the ascending aorta (ASAO), either congenital or induced by CoAo repair. In particular, it has been hypothesized that stent itself may cause or sustain hypertension. Therefore, we aimed to study the hemodynamic and structural impact following stent implantation in the normal aorta of a growing animal.
    Methods: Eight female sheep completed the study and a stent… More >

    Abstract This study aimed to assess the preventive effects of thyme oil and thymol on doxorubicin (DOX)-induced renotoxicity, cardiotoxicity, and oxidative stress in Wistar rats. Thyme oil was subjected to GC-MS analysis, which indicated that thymol was the major constituent representing 33.896%. Rats intraperitoneally injected with DOX at a dose of 2 mg/kg b.w./one per week for 7 weeks were co-treated with thyme oil and its major constituent, thymol, at doses 250 and 100 mg/kg b.w./every other day, respectively, by oral gavage for the same period. Thyme oil and thymol markedly ameliorated the raised levels of serum urea, uric acid, and… More >

    An extract of Hypericum perforatum induces wound healing through inhibitions of Ca2+ mobilizations, mitochondrial oxidative stress and cell death in epithelial cells: Involvement of TRPM2 channels

    Fuat USLUSOY1, Mustafa NAZIROĞLU2,3,*

    BIOCELL, Vol.43, No.4, pp. 271-283, 2019, DOI:10.32604/biocell.2019.08333

    Abstract The wound is induced by several mechanical and metabolic factors. In the etiology of the wound recovery, excessive oxidative stress, calcium ion (Ca2+) influx, and apoptosis have important roles. Ca2+-permeable TRPM2 channel is activated by oxidative stress. Protective roles of Hypericum perforatum extract (HP) on the mechanical nerve injury-induced apoptosis and oxidative toxicity through regulation of TRPM2 in the experimental animals were recently reported. The potential protective roles in HP treatment were evaluated on the TRPM2-mediated cellular oxidative toxicity in the renal epithelium (MPK) cells. The cells were divided into three groups as control, wound, and wound + HP treatment… More >

    Abstract Agmatine, 2-(4-aminobutyl)guanidine, has been reported to have neuroprotective effects against various neuronal damages. In this study it was investigated whether agmatine pretreatment rescues the retinal ganglion cells from oxidative injury in vitro. After differentiation of transformed rat retinal ganglion cells (RGC-5 cell line) with staurosporine, agmatine (0.0 to 100.0 μM) pretreatment was performed for 2 hours. Subsequently, they were exposed to hydrogen peroxide (0.0 to 2.5 mM) as an oxidative stress. Cell viability was monitored for up to 48 hours with the lactate dehydrogenase (LDH) assay and apoptosis was examined by the terminal deoxynucleotide transferase-mediated terminal uridine deoxynucleotidyl transferase nick… More >
