Trypanosoma brucei and related pathogens transcribe most genes as polycistronic arrays that are subsequently processed into monocistronic mRNAs. Expression is frequently regulated post-transcriptionally by cis-acting elements in the untranslated regions (UTRs). GPEET and EP procyclins are the major surface proteins of procyclic (insect midgut) forms of T. brucei. Three regulatory elements commo...

The cabbage maggot, Delia radicum (L.) is an important insect pest of eruciferous crops in upstate New York. This species causes considerable damage to seedlings and young plants by feeding on roots and stems, resulting in plant stand loss and yield loss. Five crucifer accessions (Brassica oleracea variety italica L.,'Green Comet'; B. oleracea L.,'Rapid Cycling' [Crucifer Genetics Cooperative 3...

The conserved Sir2 family of proteins has protein deacetylase activity that is dependent on NAD (the oxidized form of nicotinamide adenine dinucleotide). Although histones are one likely target for the enzymatic activity of eukaryotic Sir2 proteins, little is known about the substrates and roles of prokaryotic Sir2 homologs. We reveal that an archaeal Sir2 homolog interacts specifically with th...

The susceptibility of nine microbial species to an antimicrobial extract from Eclipta alba was screened using the well diffusion assay. Three different volumes (24, 30 and 36 μl/well) were tested. Analysis of the data revealed that all extracts from Eclipta alba showed antimicrobial activities. An N-butanol fraction showed inhibitory activities against all nine microbial species. Samples extrac...

in order to identify daldinia species in guilan province, several specimens were collected during 2011–13. a total of six taxa, including daldinia caldariorum (on morus alba); d. childiae (on parrotia persica, pterocarya fraxinifolia, morus alba, quercus sp., prunus sp., citrus sinensis, gleditschia caspica, buxus sempervirens, carpinis betulus and alnus subcordata); d. gelatinoides (on m. alba...

    Pityriasis Alba is an eruptive skin disorder which occurs as dry hypopigmented , scaly patches appears mainly in sun expose areas of skin, usually in children and young adolescents. Complete cure occurs within few years even without treatment. Few trace elements play essential roles as cofactors in pigmentary process of the skin. In this study by determination of zinc and copper levels in...

In the present study, essential oils extracted from the leaves and flowers of Lippia alba (Mill.) N.E.Br. (L. alba) were analyzed for their antimicrobial activity and their effects on osteoclasts. The periodontal pathogens, Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans; ATCC 43717), Fusobacterium nucleatum (F. nucleatum; ATCC 25586) and Porphyromonas gingivalis (P. gingivalis)...

Objective: Nymphaea alba is a medicinal plant used in tropical regions for its genital, gastrointestinal and bronchial activities. In the present study, the probable effect of the ethanol extract of the rhizome on rat uterus in the presence of standard antagonists like salbutamol and atropine and a uterine stimulant like oxytocin were examined. Methods: This work examined the effect of the etha...
