Ultraperformance liquid chromatography coupled with time-of-flight mass spectrometry (UPLC-QTOF/MS) based on a chemical profiling method was applied to rapidly evaluate the chemical consistency between sun-dried and sulfur-fumigated Radix Paeoniae Alba. By virtue of the high resolution, high speed of UPLC, and the accurate mass measurement of TOFMS coupled with reliable MarkerLynx software, fiv...

abstract east azarbaijan province is one of the most important areas for poplar production and has the highest suitability of poplar plantation in iran. three species of poplar trees included populus alba, p. nigra and p. x. euramericana are planted and usually attacked by different pests in this province. melasoma populi l., archips rosana (l.) and pemphigus filaginis are some of important pes...

Almost complete 16S rRNA sequences from seven Thermomonospora strains, Thermomonospora curvata, Thermomonospora formosensis, Thermomonospora fusca, Thermomonospora mesophila, Thermomonospora chromogena, Thermomonospora alba and Thermomonospora mesouviformis (a synonym of Thermomonospora alba) were determined and subjected to phylogenetic analysis together with the sequences from all the represe...

Albicidins are a family of phytotoxins and antibiotics which play an important role in the pathogenesis of sugarcane leaf scald disease. The albA gene from Klebsiella oxytoca encodes a protein which inactivates albicidin by heat-reversible binding. Albicidin ligand binding to a recombinant AlbA protein, purified by means of a glutathione S-transferase gene fusion system, is an almost instant an...

AIM The present investigation was designed to evaluate antiarthritic potential of fractions of hydroalcoholic extract from leaves of P. alba. MATERIALS AND METHODS Plumeria alba L. leaves were extracted with hydroalcohol (30 : 70) to obtain hydroalcoholic extract of P. alba. This extract was further fractionated with solvents ethyl acetate and n-butanol to obtain EAPA and BPA, respectively. T...

Eukaryotic DNA is packaged into nucleosomes that regulate the accessibility of the genome to replication, transcription and repair factors. Chromatin accessibility is controlled by histone modifications including acetylation and methylation. Archaea possess eukary otic-like machineries for DNA replication, transcription and information processing. The conserved archaeal DNA binding protein Alba...

Ethyl acetate soluble fraction of ethanolic extract of Eclipta alba and Lippia nodiflora was evaluated for its potential on hair growth by in vivo method. In vivo, 5 % and 10 % extract of E. alba and L. nodiflora alone and also in combination of 5 % of E. alba and 5 % of L. nodiflora in gel formulation was applied topically over the shaved skin of black mice and monitored and assessed for 30 da...

The renewed interest in the use of hybrid zones for studying speciation calls for the identification and study of hybrid zones across a wide range of organisms, especially in long-lived taxa for which it is often difficult to generate interpopulation variation through controlled crosses. Here, we report on the extent and direction of introgression between two members of the "model tree" genus P...
