Background. Annually, Saudi Arabia is the host of the Hajj mass gathering. We aimed to determine the Middle East respiratory syndrome coronavirus (MERS-CoV) nasal carriage rate among pilgrims performing the 2013 Hajj and to describe the compliance with the Saudi Ministry of Health vaccine recommendations. Method. Nasopharyngeal samples were collected from 5235 adult pilgrims from 22 countries and screened for MERS-CoV using reverse transcriptase-polymerase chain reaction. Information regarding the participants' age, gender, country of origin, medical conditions, and vaccination history were obtained. Results. The mean age of the screened population was 51.8 years (range, 18-93 years) with a male/female ratio of 1.17:1. MERS-CoV was not detected in any of the samples tested (3210 pre-Hajj and 2025 post-Hajj screening). According to the vaccination documents, all participants had received meningococcal vaccination and the majority of those from at-risk countries were vaccinated against yellow fever and polio. Only 22% of the pilgrims (17.5% of those 65 years and 36.3% of diabetics) had flu vaccination, and 4.4% had pneumococcal vaccination. Conclusion. There was no evidence of MERS-CoV nasal carriage among Hajj pilgrims. While rates of compulsory vaccinations uptake were high, uptake of pneumococcal and flu seasonal vaccinations were low, including among the high-risk population.

A series of 4-aminoquinoline derivatives were synthesized by the reaction of 4-chloro-7-substituted-quinolines with the corresponding mono/ dialkyl amines. The structures of the synthesized compounds were confirmed by NMR and FAB-MS spectral and elemental analyses. Subsequently, the compounds were examined for their cytotoxic effects on two different human breast tumor cell lines: MCF7 and MDA-MB468. Although all compounds examined were quite effective on both cell lines, the compound N 0 -(7-chloro-quinolin-4-yl)-N,N-dimethyl-ethane-1,2-diamine emerged as the most active compound of the series. It was particularly potent against MDA-MB 468 cells when compared to chloroquine and amodiaquine. The compound butyl-(7-fluoro-quinolin-4-yl)-amine showed more potent effects on MCF-7 cells when compared to chloroquine. Therefore, 4-aminoquinoline can serve as the prototype molecule for further development of a new class of anticancer agents.

Vectors for expression of h9/14, h9/14A5, h9-3A/14 were described in (1,2). Plasmids encoding the eukaryotic translation initiation factors eIF1, 1A, 4A, 4B, 4G, 5, 5B and Escherichia coli Met-tRNA synthetase were described in (3). pGL3R-glo, pGL3R-act, pGL3R-L1, pGL3R-HCV, pGL3R-EMCV, pGl3R-CrPV were the kind gift of Dr. Sergey Dmitriev (4). PCR fragments amplified from these constructs and containing the Firefly luciferase ORF fused to 5'-UTRs of -globin, -actin, LINE-1, HCV IRES or CrPV IRES under the control of SP6 promoter was inserted to pUC18 plasmid digested by HindIII and EcoRI to generate pUCglo, pUCact and pUCL1, and by PstI and EcoRI to generate pUCHCV and pUCCrPV. Vectors for in vivo expression of monocistronic mRNAs containing Firefly luciferase ORF fused to 5'-UTRs of -globin, -actin and LINE-1 were prepared by insertion of PCR fragment containing respective 5'-UTRs to pGL3R-EMCV digested by AflII and NcoI to remove upstream Renilla luciferase ORF and EMCV IRES. Plasmid pCrPV-VHLM was constructed by insertion of T7 promoter, CrPV IRES nucleotides 6028 to 6216 followed by a short ORF encoding Val-His-Leu-Met tripeptide, UAA stop codon and 100 nt random sequence taken from -glucuronidase (GUS) gene, into the pUC18 vector. Plasmids pscAluYb8, pscAluYf2, pscAluYj4 were obtained from the plasmids pscAlu/-feto and pSscAlu/LDL (1) using quick change protocol. pSAlu110 and pSAlu151 contained the Alu portion of 7SL RNA gene (nucleotides 1-74; 271-299 and 1-99; 251-299, respectively) with a closing loop GATT following position 74 or 99, preceded by the T7 promoter. [ 32 P]-MVHL-stop mRNA synthesis [ 32 P]-UTP was added to the transcription reaction. Preprolactin and MVHL-stop mRNAs were synthesized with SP6 RNA polymerase from plasmids pSP-BP4 (8) and MVHL-stop (9) linearized with EcoRI and XhoI. Capped and uncapped RNAs encoding Firefly luciferase fused to various 5'-UTRs were synthesized with SP6 RNA polymerase from plasmids pUCglo, pUCact, pUCL1, pUCCHV and pUCCrPV linearized with EcoRI. HCV-NS' and CrPV-VHLM mRNAs were synthesized with T7 RNA polymerase from plasmids pXL.HCV(40-373).NS' (10) and pCrPV-VHLM linearized with EcoRI and SspI, respectively. The mRNAs were purified by LiCl precipitation, G50 sepharose chromatography, ethanol precipitation, and resuspended in water. Non-coding AluY A , scAluY A , scAluY L , and 4.5S RNAs were synthesized with T7 RNA polymerase from plasmids pPAlu, pPscAlu/a feto, pSscAlu/LDL and pS4.5S (1) linearized with SspI, SpeI, SpeI and Andreev, D.E., Dmitriev, S.E., Terenin, I.M., Prassolov, V.S., Merrick, W.C. and Shatsky, I.N.
