To determine the epidemiology of dermatophytosis in Palestinian patients, detect changes in the etiological agents during the last three decades, and to correlate between concomitant tinea pedis infections, and other cutaneous lesions. 220 suspected dermatophytosis patients were involved in this study. In an additional 38 cases, where consultation...

Abstract Background: Economically; melons (snake cucumber and cantaloupes) are important crops cultivated in Palestine. Traditional melons are rain-fed crops. Although melons are differ in morphological traits such as shape, fruit color, taste, and flavor, low genetic variations between these crops is present. Objectives: The aims of this study are...

The effect of different levels of auxin Naphthaleneacetic acid (NAA) and cytokinin Benzyl adenin (BA) on shoot regeneration of Petunia hybrida was studied in these experiments. The regenerated shoots were grown for somaclonal variation. Seeds of Petunia hybrida_were in vitro planted onto MS basal medium. The growing seedlings were used as a source...

Albendazole is determined by differential-pulse adsorptive cathodic stripping voltammetry at a hanging mercury drop electrode using the reduction peak of its copper(II) complex at −0.28V at an accumulation potential 0.0V vs. Ag/AgCl electrode. The optimum conditions of pH, accumulation potential and accumulation time were studied. The calibration g...

Some naturally occurring plasmids like ColEl and ColK have been found to harbor site-specific recombination sequences, the core regions of such sequences have shown 82% homology when so aligned. The high degree of homology was the basis for testing the possibility of recombination between them. The sequences were cloned in the vector pUC18 in oppos...

The legJ subfamily of genes in garden pea, Pisum sativum L., encodes “minor” legumin seed storage protein polypeptides. Data on the differential expression of the 3 genes (legJ,K,L) within this subfamily is reported. The expression of one gene (legJ) is specifically upregulated during the desiccation phase of cotyledon development, when other stora...

We have identified and characterised a stability function encoded by the high copy plasmid ColK. The function is analogous to ColE1 cer and maximises stability by maintaining plasmids in the monomeric state. In vivo recombination between cer and ckr (which share more than 90% homology at the DNA sequence level) produced a functional hybrid. Sequenc...
