Organic matter and amino acid concentrations in surface sediments of Vembanad Lake – a tropical estuary, west coast of India

The surface sediments of Vembanad Lake, a tropical estuary on the west coast of India, were analyzed for carbon (TC, TOC, TIC), nitrogen (TN), amino acids and two amino sugars. C/N ratios for the surface sediments vary from 1.0–21.8, indicating terrestrial sources of organic matter. Various biogeochemical indicators based on amino acids such as Asp/β-ala and Glu/γ-aba ratios revealed that the organic matter in the 5- to 10-cm surface sediments was fresh and had not undergone extensive degradation. However, the Gluam/Galam ratio for surface sediments of Vembanad Lake varies from 0.4–2.1, indicating the dominance of bacterial biomass in the sediments. Organic matter in the sediments was found to be highly reactive, with a reactivity index ranging from 2.4–7.4, suggesting rapid remineralization. Electronic Publication     

Acute toxicity of copper sulphate to fresh water prawns

Fresh water prawns, Macrobrachium lamarrei and Macrobrachium dayanum (Crustacea-Decapoda) were subjected to static bioassay tests to ascertain the LC50 values of copper sulphate. The 24, 48, 72 and 96 hr LC50 values of copper sulphate for M. lamarrei were 0.38, 0.361, 0.343 and 0.300 mg/l and for M. dayanum were 1.634, 0.988, 0.532 and 0.418 mg/l respectively. Behavioral responses and LC50 values indicate that M. lamarrei were more sensitive to copper sulphate than M. dayanum.     

Exploring multifunctional antioxidants as potential agents for management of neurological disorders

Free radical or oxidative stress may be a fundamental mechanism underlying several human neurologic diseases. Therapy using free radical scavengers (antioxidants) has the potential to prevent, delay, or ameliorate many neurologic disorders. However, the biochemistry of oxidative pathobiology is complex, and optimum antioxidant therapeutic options may vary and need to be tailored to individual diseases. In vitro and animal model studies support the potential beneficial role of various antioxidant compounds in neurological disease. Antioxidants generally play an important role in reducing or preventing the cell damage and other changes which occur in the cells like mitochondrial dysfunction, DNA mutations, and lipid peroxidation in the cell membrane. Based on their mechanism of action, antioxidants can be used to treat various neurological disorders like Huntington’s disease, Alzheimer’s disease, and Parkinson’s disease. Vitamin E has a scavenging action for reactive oxygen species (ROS) and also prevents the lipid peroxidation. Creatine generally reduces the mitochondrial dysfunction in Parkinson’s disease (PD) patients. Various metal chelators are used in PD for the prevention of accumulation of the metals. Superoxidase dismutase (SOD), lipases, and proteases act as repair enzymes in patients with AD. Accordingly, the antioxidant defense system is found to be most useful for treating various neurological disorders.
