Red blood cell membrane stabilizing potentials of extracts of Lantana camara and its fractions
October 2010
Anti-inflammatory activity of extract of Lantana camara, Linn and its fractions was investigated using stabilization of red blood cell membrane lysing technique. Phytochemically, whole plant extract (WPE) and ethanol fraction (EF) gave positive reactions for the presence of saponins, tannins, flavonoids and cardiac glycosides. The ethyl acetate fraction (EAF) gave reactions for the presence of flavonoids while...
Effect of leaf area on dry matter production in aerated mung bean seed
October 2010
An area of plant science that is still unexplored is how leaf area affects crop dry matter production due to aeration of seed in osmoticum. In view of this, an experiment was conducted at Agricultural Research Farm of NWFP Agricultural University, Peshawar, Pakistan in the summer of 2003 and repeated in 2004. The seeds of two mung bean cultivars (NM-92 and NM-98) were primed, some for 6 h and others for 12 h in using...
Molecular phylogeny of Prorocentrum (Dinoflagellata) from the Pacific Coast of Mexico based on the parsimony analysis of fragments of LSUrDNA and SSUrDNA
July 2010
A phylogenetic analysis of the Prorocentrum species is presented, that includes the sequences of the large and small ribosomal RNA subunits from 19 cultures from 13 of the 20 species reported in the Pacific coast of Mexico; the results showed that P. micans,P. gracile and P. mexicanum were the closest of species, that planktonic may be more recent than epibenthonic species and it is...
Protein and polyphenol profile changes in soybean roots under aluminum stress
July 2010
It is well documented that aluminum (Al) toxicity is the most important constraint of crop production on acid soils. Chelation of Al in the rhizosphere with root secreted organic acid anions is a common mechanism of Al tolerance in most plants including soybean. Phenolic substances are recently implicated as additional physiological mechanism of plant Al tolerance. This study was undertaken to investigate the...
Study of inter-specific relationship in six species of Sesbania Scop. (Leguminosae) through RAPD and ISSR markers
May 2010
Six species of Sesbania were fingerprinted using RAPD and ISSR markers. Both the markers yielded a total of 249 bands out of which 243 were polymorphic in nature indicating high degrees of genetic diversity in the genus. Cluster analysis using the combined data revealed segregation of the lone species Sesbania grandiflora from the rest of the species. High boot strap values in the...
Validation of generic status of different taxa in the sub-tribe Cassiinae (Leguminosae: Caesalpinoidae) using RAPD, ISSR and AFLP markers
May 2010
Random amplified polymorphic DNA (RAPD), Inter simple sequence repeat (ISSR) and Amplified fragment length polymorphism (AFLP) markers were used to verify the segregation of the genus Cassia L. (sens. lat.) into three distinct genera namely, Chamaecrista Moench.,Senna P. Mill. and Cassia L. (sens.str.). Eighteen representatives of the three taxa were characterized...
Allelopathy as expressed by Mucuna pruriens and the possibility for weed management
April 2010
A twelve-week study was undergone to identify selective effects of Mucuna on companion crop plant and to screen Mucuna for capacity to suppress weeds. A 10% (v/w) contamination with Nigerian Bonny light crude oil was simulated for stress tolerance assessment. Mucuna pruriens supported revegetation, soil and water conservation and also contains potentially toxic BTEX and PAHs that...
Changes of some phenolic compounds and enzyme activities on infected pearl millet caused by Sclerospora graminicola
April 2010
Purification of low abundance enzymes for biochemical characterization is frequently labor and cost-intensive. The existence of co-expressing multigene families increases the complexity of the procedure even further as it occurs with plant peroxidases where only the most abundant species have been studied. In this paper we present an optimized purification method for Zo peroxidase, a low abundance isoenzyme...
An optimized procedure for the purification of Zo peroxidase (ZoPrx), a low abundance peroxidase from Japanese radish roots
November 2009
Purification of low abundance enzymes for biochemical characterization is frequently labor and cost-intensive. The existence of co-expressing multigene families increases the complexity of the procedure even further as it occurs with plant peroxidases where only the most abundant species have been studied. In this paper we present an optimized purification method for Zo peroxidase, a low abundance isoenzyme with unusual...
Food analytical evaluation of fruits and vegetables-based diets in relation to human carbohydrates
November 2009
Carbohydrates are the major nutrients of fruits and vegetables in human nutrition. Sucrose is one of the important parameters for the assessment of the commercial quality of the fruit, since consumers prefer the sweetest fruits. Results showed that fructose, glucose, sucrose contents were high in Cordia myxa (9.38, 12.75 and 29.09%) respectively and the starch content was high in Alocacia...
Fertility enhancing effects of aqueous stem bark extract of Lophira lanceolata in male Spargue dawley rats
October 2009
Lophira lanceolata stem bark extract is commonly used by herbalists in Sokoto state for the treatment of fertility related problems in males. Recently the sexual stimulatory effect of the plant in male rats has been reported. The present study examined the effect of 7 days oral administration of 100, 200 and 300 mg/kg body weight of the plant stem bark extract on fertility indices (Sperm motility, Sperm number and...
Effect of aqueous root extract of Treculia africana on haemoglobin glycosylation and plasma lipid per oxidation in streptozotocin-induced diabetic rabbits
October 2009
Measurement of glycosylated hemoglobin has been proposed to be a very sensitive index for glycemic control as various proteins, including hemoglobin, albumin, collagen, low-density lipoprotein cholesterol (LDL), or crystalline proteins has been reported to undergo non-enzymatic glycation in diabetes. In the present study an attempt was made to elucidate the effect of aqueous root extract ofTreculia africana on...
