Plant photosynthesis results in the production of molecular oxygen. An inevitable consequence of this normal process is the production of reactive oxygen species (ROS) by the transfer of electrons to molecular oxygen. Plants are adequately protected by the presence of multiple antioxidative enzymes

Growth and antioxidative response of two mangrove plants to interaction between aquaculture effluent and BDE-99.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Mangroves are subject to contamination of polybrominated diphenyl ethers (PBDEs) due to waste and wastewater disposal, and aquaculture effluent (AE) from nearby aquaculture activities. However, the response of mangrove plants to these two stresses and their interaction has seldom been reported. A

In vitro α-amylase and α-glucosidase inhibition, antioxidant, anti-inflammatory activity and GC-MS profiling of Avicennia alba Blume.

Avicennia alba Blume, is a well-known mangrove plant used in traditional medicinal practices for several human ailments.The study aimed at evaluation of antidiabetic, antioxidant, anti-inflammatory and cytotoxic activities of A. alba ethanolic leaf (AAL)

The glutathione antioxidant system as a biomarker suite for the assessment of heavy metal exposure and effect in the grey mangrove, Avicennia marina (Forsk.) Vierh.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Alterations in the glutathione antioxidant system and lipid peroxidation in Avicennia marina were studied under laboratory and field conditions. The activity of glutathione peroxidase (GPx) was found to respond to Zn exposure, and a significant positive relationship between leaf Zn concentration and

Effect of a polybrominated diphenyl ether congener (BDE-47) on growth and antioxidative enzymes of two mangrove plant species, Kandelia obovata and Avicennia marina, in South China.

The effects of BDE-47 on the growth and antioxidative responses of the seedlings of Kandelia obovata (Ko) and Avicennia marina (Am) were compared in an 8-week hydroponic culture spiked with different levels of BDE-47, 0.1, 1, 5 and 10 mg l(-1). The two highest BDE-47 levels significantly suppressed

Antioxidant, Hypoglycemic, and Neurobehavioral Effects of a Leaf Extract of Avicennia marina on Autoimmune Diabetic Mice.

Mangrove wetland receives nutrient-rich aquaculture effluent (AE) from nearby farming activities and polybrominated diphenyl ethers (PBDEs) from the production and usage of flame retardants. The effects of BDE-209 (the most common PBDE congener), AE and their combination on two true mangrove

Identification and kinetic characterization of a novel superoxide dismutase from Avicennia marina: An antioxidant enzyme with unique features.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

A novel Cu/Zn-superoxide dismutase was extracted from Avicennia marina and purified. The sample was collected from Khamir port located in the north shore of Persian Gulf. The purification procedure comprised of (NH4)2SO4 precipitation followed by CM-Sephadex C-50 and DEAE-Sepharose chromatography,

Ecophysiological differences between three mangrove seedlings (Kandelia obovata, Aegiceras corniculatum, and Avicennia marina) exposed to chilling stress.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Although the cold-resistant ability of mangroves varies greatly with species, the physiological mechanism remains unclear. The chilling stress effects on morphological changes, photosynthetic pigments, reactive oxygen species (ROS), malondialdehyde (MDA) and several antioxidants, were studied in

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Four new jacaranone analogs, marinoids F-I (1-4), were isolated from the fruits of a Beibu Gulf mangrove Avicennia marina. The structures were elucidated based on analysis of spectroscopic data. Marinoids F and G are shown to be diastereoisomers of chlorocornoside, a new halogen containing marine

Uptake and accumulation of polycyclic aromatic hydrocarbons in the mangroves Avicennia marina and Rhizophora mucronata.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

This study investigated the uptake and accumulation of polycyclic aromatic hydrocarbons (PAHs) in two mangrove species, Avicennia marina and Rhizophora mucronata. We tested the hypothesis that A. marina would absorb and accumulate more PAHs than R. mucronata. One-year old seedlings of both species

Leaf miner-induced morphological, physiological and molecular changes in mangrove plant Avicennia marina (Forsk.) Vierh.
