Abstract: The avalaibility of simple and efficient techniques for inducing genetic variation, such as use of radiation for inducing of mutation and selection for desired traits is an essential component of any plant breeding programme. The goal of the mutation breeding in selected Amaranthus spp. was to enhance quality and quantity of amaranth grain. We have found some promising mutant lines with high coefficient of nutritional quality. Considering overall nutrition values, the lines C15/3, C27/5 and C82/1 are most promising genotypes, which could be possibly used in a future breeding programme.

Abstract: The aim of the present study is to evaluate the wound healing activity of flavonoid fraction of Cynodon dactylon in swiss albino mice. The wound healing property of the fraction was studied in excision wound which was inflicted by cutting away 0.5cm standard full thickness of wound was created on the predetermined dorsal area. The flavonoid fraction of Cynodon dactylon were applied externally daily on the excised wound area for 8 days. This fraction facilitates the healing process as evidenced by increase in collagen and protein and decrease in lipid peroxide in granulation tissue. Thus, the enhanced wound healing may be due to free radical scavenging activity of the flavonoid fraction.

Abstract: In recent years, the demand for a natural plant-based polymer with potential functions from plant sources has increased considerably. The main objective of the current study was to study the effect of chemical extraction conditions on the rheological and functional properties of the heteropolysaccharide/protein biopolymer from durian ( Durio zibethinus) seed. The efficiency of different extraction conditions was determined by assessing the extraction yield, protein content, solubility, rheological properties and viscoelastic behavior of the natural polymer from durian seed. The present study revealed that the soaking process had a more significant ( p < 0.05) effect than the decolorizing process on the rheological and functional properties of the natural polymer. The considerable changes in the rheological and functional properties of the natural polymer could be due to the significant ( p < 0.05) effect of the chemical extraction variables on the protein fraction present in the molecular structure of the natural polymer from durian seed. The natural polymer from durian seed had a more elastic (or gel like) behavior compared to the viscous (liquid like) behavior at low frequency. The present study revealed that the natural heteropolysaccharide/protein polymer from durian seed had a relatively low solubility ranging from 9.1% to 36.0%. This might be due to the presence of impurities, insoluble matter and large particles present in the chemical structure of the natural polymer from durian seed.

Abstract: water soluble protein fraction (WSPF) content along with the SOD and the CAT activities were comparatively monitored in leaf blades, sheaths and roots. S-deprivation progressively diminished WSPF first in the sheaths, two days later in the blades, and four days later in the root. SOD activity per mg WSPF decreased at d2, whilst it increased for the next four days. After d6, SOD activities of roots and sheaths decreased, followed by the blades at d10. CAT activity per mg WSPF at d2 decreased only in blades, whilst increased in both sheaths and roots (more in sheaths). After d6 decreased CAT activity was found only in roots. No other decreases were observed in blades and sheaths. SOD and CAT specific activities on DM basis presented an oscillation pattern with the increase of DM. S-deprivation altered this picture, by reversing the oscillation pattern and by decreasing the trendlines. SOD specific activity initially decreased in –S sheaths and roots, whilst it remained unchanged in –S blades. Then it increased abruptly, decreased in an exponential manner and stabilised in all three organs. S-deprivation caused an early fluctuation of the CAT activity and then diverse responses; in blades a late increase in CAT activity was observed and decreases in the other two organs. S-deprivation seemed to reverse the oscillation pattern of CAT specific activity differentially for each organ type.

Abstract: red scorpion (mesobuthus tamulus or buthus tamulus) venom samples were collected at different regions of india: western (chiplun and ahmednagar from maharashtra state) and southern (ratnagiri and chennai from tamil nadu state). the action of whole venoms on the blood sodium levels of mice was assessed using flame photometry. seven peptides were common to all venom samples. they were separated using the native polyacrylamide gel electrophoresis (page) technique and their activities were also studied using flame photometry. there was a decrease in the concentration of sodium ions in the serum, which suggested the blockage of such ions by scorpion venom toxins. among the 10 protein bands isolated, the band at 79.6 kda presented maximum activity in decreasing serum sodium ions concentration. whole venom from chiplun region also showed maximum activity. the western blotting technique demonstrated that the anti-scorpion venom sera produced by haffkine biopharmaceuticals corporation ltd., india, neutralized all four venom samples.

Abstract: To investigate the effect of gamma irradiation on the nutritional quality of maize and sorghum grains, packs were exposed to doses of 0 and 2 kGy in a 60 Co package irradiator. Irradiated and non-irradiated samples were stored at refrigeration temperatures. Proximate composition, minerals content, minerals bio-availability, tannins content, phytic acid content, protein fractions and in vitro protein digestibility were evaluated. The results indicated that gamma irradiation caused no effect on proximate composition, minerals content and minerals bioavailability. For protein fractions, in both maize cultivars no significant differences were observed in all fractions, except in prolamins and glutelins of Maize 75. While for sorghum significant increase in globulins, prolamins and glutelins was observed. While, gamma irradiation reduced the phytic acid and tannins contents significantly. The in vitro protein digestibility of maize cultivars was increased significantly, while the digestibility of sorghum was reduced.

Abstract: The usage of the mare’s milk as functional food especial for children intolerant to cow’s milk, with neurodermitis, allergies and similar disorders desiring to improve the quality of life is fiercely debated for last decades but there were no scientific studies to suggest such use of mare’s milk based on scientific research. The objectives of this study were to determine similarities of mare’s milk in comparison with milk of ruminants (cattle, sheep and goat) and human milk in terms of milk composition and protein fraction as whey proteins, caseins and micelles size. All differences were discussed regarding usage of mare’s milk in human diet and compared to milk which is usually used in human nutrition. Regarding composition, the mare’s milk is similar to human milk in of crude protein, salt and lactose content, but it has significantly lower content of fat. Fractions of main proteins are similar between human and mare’s milk, except nitrogen casein (casein N) which has twice lower content in human than in mare’s milk. Content of casein N from all ruminants’ milk differ much more. Just for true whey N and non-protein nitrogen (NPN) similar content as human and mare’s milk has also goat milk. The casein content is the lowest in human milk; this content is three times greater in mare’s milk and six to seven times greater in goat’s and cow’s milk, while in sheep’s milk it is more than 10 times grater. In many components and fractions mare’s milk is more similar to human milk than milk of ruminants. A detail comparison of protein fraction shows quite large differences between milk of different species. More study and clinical research are needed that can recommend usage of mare’s milk in human diet as functional food on scientific bases.

Abstract: Objective: To identify electrocardiographic parameters that predict extent of early improvement in ejection fraction (EF) in patients with stress cardiomyopathy. Methods: We collected baseline clinical, ECG and imaging data and follow up echocardiography data on 30 consecutive patients with stress cardiomyopathy. The relationship between baseline ECG parameters and Delta EF was evaluated by univariate and multivariable analysis. Results: Median EF improved from 35% to 55% (p < 0.0001). Delta EF showed negative correlation with number of leads with T inversion (p = 0.01) and QT interval (p = 0.02). The number of leads with T inversion was independently associated with Delta EF (coefficient ?4.878, p = 0.04). Conclusion: The number of leads with T wave inversion is negatively correlated with and is an independent predictor of the extent of early improvement of EF in patients with stress cardiomyopathy. Hence the ECG at initial presentation can be used as a simple tool to predict LV function recovery.
