The Potential Impact of Electronic Services to Rafah Municipality's Operational Excellence

This study investigates the potential impact of electronic services in achieving operational excellence, using the Rafah municipality as a case study. The ARIMA model was employed in the study to forecast changes in the municipal cost trend. Additionally, a questionnaire was designed, to collect data from the study population of 329 employees in the Rafah municipality, a descriptive-analytical technique using the least squares method was utilized to estimate the regression equation of the operational excellence components (time and cost). The results demonstrate that the anticipated costs will reduce, with a relative decline rate of 1% for the years 2023, 2024, and 2025. Furthermore, the statistical findings showed that a change in the level of software package measurement of one unit would result in a 0.50-degree improvement in the transaction time index and a 0.29-degree decrease in cost. According to the results cited, electronic services had a statistically significant impact on the municipality of Rafah's achievement of operational excellence. Therefore, this study recommends implementing digitization to achieve operational excellence and establishing a technology unit that would be entrusted with supervising all facets of managing and improving municipal systems.

A phase I study of combination chemotherapy with gemcitabine and oral UFT for advanced non-small cell lung cancer

A phase I study was carried out to determine the optimal dose and administration schedule for combined UFT plus gemcitabine therapy in patients with non-small cell lung cancer. Twenty-four patients (including 11 patients previously treated with cisplatin as the key drug) received oral UFT 400 mg m−2 on days 1 to 14 with intravenous infusions of gemcitabine (800 mg m−2 on days 8 and 15, or 900 mg m−2 on days 8 and 15, or 900 mg m−2 on days 1, 8 and 15). The most appropriate dosing option appeared to be 400 mg m−2 per day of oral UFT for 14 consecutive days with 900 mg m−2 gemcitabine on days 8 and 15. Eight of the 24 patients achieved partial response. The combination chemotherapy UFT and gemcitabine was well tolerated and may benefit patients with advanced non-small cell lung cancer. A multicentre phase II study using a 3-weekly regimen is in progress

Transcriptional and Proteomic Analysis of the Aspergillus fumigatus ΔprtT Protease-Deficient Mutant

Aspergillus fumigatus is the most common opportunistic mold pathogen of humans, infecting immunocompromised patients. The fungus invades the lungs and other organs, causing severe damage. Penetration of the pulmonary epithelium is a key step in the infectious process. A. fumigatus produces extracellular proteases to degrade the host structural barriers. The A. fumigatus transcription factor PrtT controls the expression of multiple secreted proteases. PrtT shows similarity to the fungal Gal4-type Zn(2)-Cys(6) DNA-binding domain of several transcription factors. In this work, we further investigate the function of this transcription factor by performing a transcriptional and a proteomic analysis of the ΔprtT mutant. Unexpectedly, microarray analysis revealed that in addition to the expected decrease in protease expression, expression of genes involved in iron uptake and ergosterol synthesis was dramatically decreased in the ΔprtT mutant. A second finding of interest is that deletion of prtT resulted in the upregulation of four secondary metabolite clusters, including genes for the biosynthesis of toxic pseurotin A. Proteomic analysis identified reduced levels of three secreted proteases (ALP1 protease, TppA, AFUA_2G01250) and increased levels of three secreted polysaccharide-degrading enzymes in the ΔprtT mutant possibly in response to its inability to derive sufficient nourishment from protein breakdown. This report highlights the complexity of gene regulation by PrtT, and suggests a potential novel link between the regulation of protease secretion and the control of iron uptake, ergosterol biosynthesis and secondary metabolite production in A. fumigatus

Multiple introductions of reassorted highly pathogenic avian influenza viruses (H5N8) clade 2.3.4.4b causing outbreaks in wild birds and poultry in Egypt

Recently, an increased incidence of outbreaks of highly pathogenic avian influenza (HPAI) H5N8 in poultry linked to infected migratory birds has been reported from different European, Asian and African countries. In Egypt, incursion of HPAI H5N8 virus of clade 2.3.4.4b has been recently registered. Full genomic characterization of 3 virus isolates from wild birds and poultry (backyard and commercial farm sectors) showed high nucleotide similarity among the HA, NA, M, and NS gene segments of the three Egyptian HPAI H5N8 viruses, indicating that they are descendants of a common ancestral virus. However, the analyzed Egyptian H5N8 viruses revealed distinct genotypes involving different origins of the PB2, PB1, PA and/or NP segments. In genotype-1 represented by strain A/common-coot/Egypt/CA285/2016 the PB2 and NP segments showed closest relationship to H5N6 and H6N2 viruses, recently detected in Italy. The second is replacement of PB1 and NP genes A novel reassortant, represented by strain A/duck/Egypt/SS19/2017, showed an exchange of PB1 and NP genes which might have originated from H6N8 or H1N1 and H6N2 viruses. Finally, replacement of PA and NP genes characterized strain A/duck/Egypt/F446/2017. Bayesian phylogeographic analyses revealed that Egyptian H5N8 viruses are highly likely derived from Russian 2016 HPAI H5N8 virus (A/great_crested_grebe/Uvs-Nuur_Lake/341/2016 (H5N8)) and the reassortment likely occurred before incursion to Egypt
