Today, the recombinant proteins become a major foundation of different industrial sectors. Products ofthese industries enhance the fields of medicine, pharmacology, agriculture, nutrition, petrochemicals,paper, textiles and many others. Since the mid 1980s, recombinant DNA technology has enabled thedevelopment of a wide diversity of vectors for expression of the desired recombinant protein innumerous prokaryotic and eukaryotic organisms. Baculovirus expression vector system is consideredone of the most successful and widely acceptable means for the production of recombinant proteins inextremely large quantities.

The incidence of head and neck cancer was reported to be higher in more developed countries with an increase in incidence lately among younger age groups. The need for improvement of awareness of oral cancer and potentially malignant oral disorders is crucial. This study aims to identify the level of awareness of diagnostic and management protocols in the dental community. An English survey was arranged and sent via email to undergraduate students, postgraduate students, and faculty members at the dental school Cairo University. The questions focused on the early detection and level of awareness of oral cancer. Results were then analyzed to assess levels of awareness at the different education levels of the participants. Eight hundred sixty-eight responded out of the sent 5052 during the period between October 2015 and January 2016. The average results of the faculty staff members were higher than that of the student groups and participants with regular continuous assessment and knowledge refreshment achieved higher results. The results of this survey have pointed out areas of lack of awareness among the targeted population. The results have been brought up to the knowledge of policy makers to enable the improvement of level of awareness and assessment of risk factors for oral cancer.

This study was conducted to revise the taxonomic identity and clarify inter-and intra-specific relationships among the studied wild and cultivated Hordeum taxa in Egypt. The studied taxa included Hordeum marinum subsp. gussoneanum, H. marinum subsp. marinum, H. Hordeum leporinum, Hordeum glaucum, Hordeum spontaneum and Hordeum vulgare. The results revealed that unweighted pair group method with arithmetic mean (UPGMA) dendrogram showed a considerable degree of dissimilarity among the studied Hordeum taxa at 1.50 dissimilarity distance. It divided the studied taxa into four groups
