Chilling whole rice seedlings at 5 degrees C significantly increased the time needed to recover linear growth and reduced the subsequent linear rate of radicle growth. Subjecting nonchilled seedlings to a 45 degrees C heat shock for up to 20 min did not alter subsequent growth, whereas a 3 min heat shock was optimal in reducing growth inhibition caused by 2 days of chilling. The activity of fiv...

AIM We aimed to assess relevance of mineral, trace element and heavy metal levels in patients with malignant gliomas. METHODS In this study, erythrocyte catalase (CAT), and carbonic anhydrase (CA), serum copper (Cu.), zinc (Zn), lead (Pb), iron (Fe), cadmium (Cd), cobalt (Co), manganese (Mn), and magnesium (Mg) levels were measured in 22 healthy humans and 22 malignant glioma patients. Metal ...

: Multi-walled carbon nanotubes (MWCNTs) are being utilized in various fields. With regard to their numerous applications, MWCNT-induced toxicity has not been extensively investigated. Thus, the present study sheds light on protective effect of caffeic acid (CA) mitochondrial kidney caused by MWCNTs Wistar rats employing MTT assay as well reactive oxygen species (ROS) indices, based measuring g...

Cadmium (Cd) and selenium (Se) could jointly affect plant growth. To investigate the of Se on Cd accumulation in Juglans regia physiological mechanism by which regulates Cd-induced oxidative stress, this study, effects different foliar application doses (0 (Se0), 20 (Se20), 200 (Se200) ?M) J. (variety Xinfeng) seedlings under stress (5 mM) were determined. The results show that exogenous (Se20 ...

Catalase (CAT, OMIM: 115500) is an endogenous antioxidant enzyme and genetic variations in the regulatory regions of the CAT gene may alter the CAT enzyme activity and subsequently may alter the risk of oxidative stress related disease. In this study, potential influence(s) of the A-21T (rs7943316) and C-262T (rs1001179) genetic polymorphisms in the CAT promoter region, using the ALGGEN-PROMO.v...

The co-immobilization of Aspergillus niger glucose oxidase (GOD) with bovine liver catalase (CAT) onto florisil (magnesium silicate-based porous carrier) was investigated to improve the catalytic efficiency of GOD against H2O2 inactivation. The effect of the amount of bound CAT on the GOD activity was also studied for 12 different initial combinations of GOD and CAT, using simultaneous and sequ...

(1) Background: We aimed to analyze the oxidative status of patients with unstable angina pectoris (UA), as well determine correlation these parameters between coronary arterial and peripheral venous blood samples. (2) Methods: The study included 47 human subjects UA 45 control subjects. performed clinical examinations, hemodynamic angiography measures. Also, in samples, we measured routine lab...

In a variety of vascular disorders, endothelial cells (ECs) are exposed to high levels of reactive oxygen species (ROS) generated intercellularly. Recently, several anti-oxidants, including catalase, have been suggested to be cytoprotective against the development of atherosclerosis. The object of this study was to investigate whether adenovirus-mediated gene transfer of catalase in ECs can att...

Pollution by heavy metals is a serious problem due to their toxicity and ability to accumulate in the biota. In vivo effects of Cadmium (Cd) levels of expression on antioxidant enzymes such as Catalase (CAT) and Glutathione-S-transferase (GST) were investigated in liver, kidney, gill and brain tissues of freshwater Catfish, Clarias gariepinus. CAT is a common antioxidant enzyme which breaks dow...
