From the aerial parts of Tanacetum balsamita L. (Compositae) a flavonol aglycon was iso­lated using chromatographic techniques. The structure of this compound was determined using spectroscopic methods (UV, H-NMR and MS) as 3',4',5,7-Tetrahydroxy flavonol (Quercetin).

an inoculation of virulent leishmania major is known as leishmanization (lz) which is proven to be the most effective control measure against cutaneous leishmaniasis (cl). however, using lz is restricted due to various side effects such as uncontrolled lesion development. in the present research, the efficacy of cationic nanoliposomes containing cpg oligodeoxynucleotides (cpg odn) as an improve...

introduction: gp63 is a major surface protease of leishmania promastigotes that plays an important role in its virulance. as gp63 on its own can not develop an effective protection against leishmaniasis, the goal of this study was to evaluate the protective effect of gp63 conjugated with tetanus toxoid (tt) and vitamin d3 in susceptible balb/c mice against cutaneous leishmaniasis. methods: this...

Cyanophos is commonly used in Egypt to control various agricultural and horticultural pests. It is not easily hydrolyzed and thus they are highly persistent and accumulate in various aquatic compartments such as rivers and lakes. Such issues may be solved by phytoremediation, which is the use of plants for the cleanup of pollutants. Here, we tested Plantago major L. to clean water polluted with...

The nuclease is a surface enzyme unique to trypanosomatid parasites. These organisms lack the pathway for de novo purine biosynthesis and thus are entirely dependent upon their hosts to supply this nutrient for their survival, growth, and multiplication. There is a cluster on chromosome 30 which carries 2 copy of nuclease genes and 5 identical nuclease like proteins in L. major which are in cis...

The amino acid L-arginine plays a crucial role in the regulation of immune responses. We have recently shown that uncontrolled replication of Leishmania parasites at the site of pathology correlates with high levels of arginase activity in nonhealing leishmaniasis and that this elevated arginase activity causes local depletion of L-arginine. To further our understanding of the impact of L-argin...

This study focuses on lead detoxification using roots, stems, leaves and whole plants of Plantago major L. and Phaseolus vulgaris L. (decoration kidney bean) as a ball hanging hydroponically in deionized water supplemented with concentrations of lead ion under different duration times and temperatures regimes. Roots of studied plants showed that the highest removal of lead than other parts, whi...
