The effects of different concentrations of copper (0–800 μmol) on growth, protein contents, peroxidase (POD), catalase (CAT), superoxide dismutase (SOD), and phenylalanine ammonia-lyase (PAL) in Jatropha curcas L. seedlings were assessed by means of pot experiments. Results suggested that increased copper concentrations lead to decreased shoot elongation and seedling biomass. Protein content in...

In order to investigate the effects of artificial substrates on shrimp growth, spatial distribution and non-specific immunity factors, such as phenoloxidase (PO), superoxide dismutase (SOD), peroxidase (POD), antibacterial activity (Ua), lysozyme (Ul) and hemolysin activity, 30-day old Litopenaeus vannamei post-larvae (PL30) were reared intensively for 60 days at a density of 500 shrimp m of wa...

Thermal inactivation of peroxidase (POD) in an extract of Picea omorika (Pancić) Purkyne needles initiated by heat treatment was studied. This is the first study of this kind on a conifer species. Non-linear regression analysis was applied on the inactivation rate data, combining Mitscherlich and Arrhenius equations, treating time and temperature simultaneously as explaining variables. We deter...

In present study, growth, arsenic accumulation, and antioxidant responses in root of Isatis cappadocica were investigated in response to application of arsenate and phosphate. Reduction in root dry weights was significant with 1200 µM arsenate and 5 µM phosphate treatments. Phosphate had a steady effect on root dry weight improvement, especially in high arsenate treatments ≥ 200 μM. As concentr...

The antioxidant effect of an aqueous extract of Phaseolus vulgaris pods, an indigenous plant used in Ayurvedic medicine in India, was studied in rats with streptozotocin-induced diabetes. Oral administration of Phaseolus vulgaris pod extract (PPEt; 200 mg/kg body weight) for 45 days resulted in a significant reduction in thiobarbituric acid reactive substances and hydroperoxides. The extract al...

Z. Naturforsch. 54c, 496-500 (1999); received January 11/March 27. 1999 Dioscorea esculenta. Peroxidase. Ion Exchange C hrom atography. Gel Filtration We isolated two types of peroxidase from the fresh tuber of Dioscorea esculenta using a com bination of ion exchange and gel filtration chrom atography. The results showed one type to be neutral and the other to be strongly ionic. The strongly io...

To elucidate how physiological and biochemical mechanisms of chilling stress are regulated by abscisic acid (ABA) pretreatment, pepper variety (cv. 'P70') seedlings were pretreated with 0.57 mM ABA for 72 h and then subjected to chilling stress at 10°/6°C (day/night). Chilling stress caused severe necrotic lesions on the leaves and increased malondialdehyde and H(2)O(2) levels. Activities of mo...

Materials and Methods: A total of 90 subjects of both sex groups, aged between 45–60 years were enrolled for this study. Of 90 subjects, 60 were patients with type 2 diabetes and 30 were healthy without diabetes. Glycemic status was categorized as good glycemic control if glycated hemoglobin (HbA1c) <7% and poor glycemic control if HbA1c ≥7%. Serum fasting blood sugar (FBS) was measured by Gluc...

Through a common garden (provenance) experiment, we investigated the metabolic responses to climatic stress with regard acclimation potential of different European beech (Fagus sylvatica L.) populations. Selected enzymatic and non-enzymatic antioxidants were analyzed in leaves. Peroxidase (POD) polyphenol oxidase (PPO) enzyme activity, total protein content as well ABTS [2.2’-azino-bis-(3-etylb...
