BACKGROUND Cataract is the leading cause of blindness in elderly people worldwide, especially in developing countries. Studies to identify strategies that can prevent or retard cataract formation are urgently required. This study aimed to investigate the potential mechanism of the cytoprotective effects of curcumin in in vivo and in vitro experiments. METHODS Male Wistar rats were randomly di...

AIM To evaluate the effects of metformin (Met) on inflammation, oxidative stress, and bone loss in a rat model of ligature-induced periodontitis. MATERIALS & METHODS Male albino Wistar rats were divided randomly into five groups of twenty-one rats each, and given the following treatments for 10 days: (1) no ligature + water, (2) ligature + water, (3) ligature + 50 mg/kg Met, (4) ligature + 10...

Cimicifugae rhizoma (C. rhizoma) called Shengma (Chinese), Seungma (Korean), and Shoma (Japanese) is primarily derived from Cimicifuga heracleifolia Komarov or Cimicifuga foetida Linnaeus. C. rhizoma is used for anti-inflammatory, analgesic, antipyretic remedy and alternative for hormone replacement therapy. The aim of this study was to determine the dose-dependent anti-inflammatory and tumor s...

Citrus Tristeza disease, caused by CTV (Citrus tristeza virus), committs citrus plantations around the world and specifically attacks phloem tissues of the plant. The virus exists as a mixture of more or less severe variants, which may or may not cause symptoms of Tristeza. The objective of this study was to analyze the changes caused by CTV in the proteome of stems of sweet orange, as well as ...

This study investigates the role of extracellular SOD (EC-SOD), the major extracellular antioxidant enzyme, in skeletal muscle ischemia and reperfusion (I/R) injury. Pedicled cremaster muscle flaps from homozygous EC-SOD knockout (EC-SOD-/-) and wild-type (WT) mice were subjected to 4.5-h ischemia and 90-min reperfusion followed by functional and molecular analyses. Our results revealed that EC...

The effects of heparin-superoxide dismutase (SOD) conjugate (heparin-SOD) on γ-radiation induced DNA damage in vivo and in vitro were evaluated. Plasmid pcDNA3.0 solution was mixed with heparin-SOD, SOD, and a mixture of heparin and SOD (heparin + SOD), respectively, and irradiated with (60)Co at a dosage of 120 Gy. DNA injury was analyzed using agarose gel electrophoresis. The results showed t...

A protective effect of the SOD (superoxide dismutase)-DIVEMA (divinyl ether and maleic anhydride) conjugate on I-R (ischemia-reperfusion) liver injury was demonstrated. Twenty minutes of normothermic hepatic ischemia was induced by clamping the portal triad of Sprague-Dawley rats. Five minutes before the end of ischemia, SOD, SOD-DIVEMA, or NaCl (0.9%) was given intravenously. Using intravital ...
