...NA viruses undergo rapid mutations which compromises the immune protection of conventional vaccines. RNA interference (RNAi) has becoming a feasible strategy against various virus infections. Recently, a significant advance in RNAi technology is the use of artificial microRNAs (amiRNAs) to fight virus infections. However, different strategies are needed to prevent virus variation or mutation escape. This review is intended to present the current situation of a...

This study aimed at identification of mutations in GPR54 and GNRHR genes and their correlation with HH in Pakistani boys. Thirty one boys with delayed puberty and thirty one normal age matched controls were examined. Genomic DNA was extracted and amplified by PCR using specific primers for GPR54 and GNRHR splice site exons.

Multiple area of mutations a long 5′ UTR amplicon, were observed by alignment of BVDV- Egypt-020-1ncp BVDV-Egypt-020-3ncp and BVDV-Egypt-020-2ncp.While Npro based detection was not succeeded to detect our HoBi-like Pestivirus in original samples or even in viral isolate despite their ability to amplify the BVDV RNA of reference strain (NDAL). Precisely, this study provides the first evidence of HoBi-like pestivirus infection in Egypt, raising pro...

Evaluation of sperm quality in terms of concentration, volume, motility, and sperm viability was performed using photometry, flow cytometry, and a computer assisted sperm analyzer. The above studies indicate that all four nucleotide substitutions analyzed in exon 4 of AQP7 gene affect the individual quality characteristics of the analyzed semen of Holstein-Fries...

To conclude, PSEN1 E280A mutation is present in GNTs seizures patients, and greatly associated with multiple types of seizures and gender. The requirement of larger sample studies and long-term follow-up is implemented for further confirmatio...
