Indoleamines regulate a variety of physiological functions during the growth, morphogenesis and stress-induced responses in plants. Present investigations report the effect of NaCl stress on endogenous serotonin and melatonin accumulation and their differential spatial distribution in sunflower (Helianthus annuus) seedling roots and cotyledons using HPLC(More)

Edible mushrooms are excellent sources of protein, have low-fat content and are free of cholesterol. They are(More)
Studies on knockout mutants and conditional mutants are invaluable to biological research and have been used extensively to probe the intricacies of biological systems through loss of function associated with attenuation of a particular protein. Besides, RNAi technology has been developed in recent years to further aid the process of scientific inquiry.(More)
In this paper, the authors have presented a robust watermarking scheme which employs both the Discrete Cosine Transform (DCT) and the Singular Value Decomposition (SVD). The proposed scheme starts with transformation of an original grayscale cover image into a transformed image using block based DCT. From each transformed block, the middle band DCT(More)
— Digital color image segmentation of noisy images is nowadays an important area of research in the field of computer vision. This paper advocates an effective image segmentation approach for noisy images. The approach can broadly be divided into application of two strategies namely noise removal from noisy images using median filtering on initial digital(More)
The possible protective role of ethanolic extract of A. indica tuber (EEAIT) in hepatotoxicity and apoptosis of liver caused by alcohol in rats was investigated. Treatment of rats with alcohol (3 g ethanol per kg body weight per day for 15 days intraperitoneally) produced marked elevation of liver biomarkers such as serum alanine aminotransferase (ALT),(More)
Deposition of human amylin or islet amyloid polypeptide (hIAPP) within the β-cells of the pancreatic islet of Langerhans is implicated in the etiology of type 2 diabetes mellitus (T2Dm). Accumulating evidences suggest that increased body iron stores, iron overload, and, in particular, higher heme-iron intake is significantly associated with higher risk of(More)
Redox active iron is utilized in biology for various electron transfer and catalytic reactions essential for life, yet this same chemistry mediates the formation of partially reduced oxygen species (PROS). Oxidative stress derived from the iron accumulated in the amyloid plaques originating from amyloid β (Aβ) peptides and neurofibrillary tangles derived(More)
Understanding the physiological and biochemical basis of abiotic stress tolerance in plants has always been one of the major aspects of research aiming to enhance plant productivity in arid and semi-arid cultivated lands all over the world. Growth of stress-tolerant transgenic crops and associated agricultural benefits through increased productivity, and(More)
Recent evidence has established the colocalization of amyloid-rich plaques and heme-rich deposits in the human cerebral cortex as a common postmortem feature in Alzheimer's disease (AD). The amyloid β (Aβ) peptides have been shown to bind heme, and the resultant heme-Aβ complexes can generate toxic partially reduced oxygen species (PROS) and exhibit(More)
