Objective:To detect the subtype characterization and drug-resistant mutations in HIV-1 strains after the refugee movement from Syria to Turkey between 2011 and 2014 in south east border lines. Methods: A total of 65 patients were included in this study, of which 57(88%) patients were antiretroviral therapy-naive patients. HIV-1 RNA was detected and quantii ed by realtime PCR assay. HIV-1 subtypes and circulating recombinant forms(CRFs) were identii ed by phylogenetic analysis(neighbor-joining method), and drug-resistant mutations were ***: Three major HIV groups were indicated. Two of these groups were located in subtype B. The other group showed heterogeneity. Subtype B(48/65, 73.8%), followed by CRFs(12/65, 18.5%) was the most common strain. Subtype of CRFs consisted of CRF01_AE(9/65, 13.8%) and CRF02_AG(3/65, 4.6%). Subtype C(1/65, 1.5%), sub-subtypes A1(2/65, 3.1%) and F1(2/65, 3.1%) were also detected with low prevalence. The rate of overall primary antiretroviral resistance was 4.9%(3/61). Drug-resistant rate for non-nucleoside reverse transcriptase inhibitors was 4.9%. The thymidine analogue mutation rate was 13.1%(8/61).Conclusions: HIV molecular epidemiology studies are necessary to determine transmission patterns and spread. Subtype B and CRF01_AE, CRF02_AG are the most prevalent strains in the south-east of Turkey. However, subtype C, sub-subtypes A1 and F1 are of low prevalence but persist in the south-east of Turkey. In the near future, changing of HIV epidemiology will be possible in Turkey due to migration movement in border lines and resistance testing will play an important role in HIV management.

Objective: Evaluating the bio-reducing activity and various potential, annotates the biological entitties of Fagonia cretica. Method: By fractionating the crude extract with different ethanol-water fraction mixture. This substantiates the reduction potential for the biological synthesis of AgNPs, its antioxidant, anti-urease and anti-Tyrosinase activity. Results: UV-visible spectra confirm the bio-reducing potential for Ag NPs with the optimized 50% ethanol-water fraction mixture. Transmission electron microscopy (TEM) confirmed the round shaped AgNPs with an average size of 16 nm in optimized 50% fraction mixture. Further evaluating Ethanol-water fraction with 90% and 70% of plant extract showed more potentials for Anti-Tyrosinase and Anti-urease activity. Moreover, diluted 30% fraction exhibits two folds higher Anti-oxidant and Anti urease activity. Conclusion: Overall, this work showed that 50% Ethanol-water fraction has potentially active molecules (among all fractions) primarily involved in bio-reducing potential of Ag NPs and enzymatic assay while 90% mixture proved to be least active. This study suggested electing the optimum mixture fraction of 50% ethanol-water in order to screen the bioactive compounds and to inculcate their activity status for clinical trials.
