How does the public perceive facial recognition technology and how much do they accept facial recognition technology in different political contexts? Based on online surveys resembling the Internet-connected population in China, Germany, the United Kingdom, and the United States, our study finds that facial recognition technology enjoys generally highest acceptance among respondents in China, while acceptance is lowest in Germany, and the United Kingdom and the United States are in between. A closer examination through the lens of an integrated technology acceptance model reveals interesting variations in the selected four countries based, among other factors, on socio-demographic factors as well as perceived consequences, usefulness, and reliability of facial recognition technology. CX-5461 manufacturer While previous research has pointed out that facial recognition technology is an instrument for state surveillance and control, this study shows that surveillance and control are not foremost on the minds of citizens in China, Germany, the United Kingdom, and the United States, but rather notions of convenience and improved security.Pre-Exposure Prophylaxis (PrEP) is a potential game-changer for HIV. We used PrEP introduction for Young Women Who Sell Sex (YWSS) in a rural South Africa district to understand community norms and PrEP coverage in YWSS. Between 2017 and 2018, we measured awareness and uptake of PrEP in a representative cohort of 2184 Adolescent Girls and Young Women (AGYW) aged 13-22. We conducted group discussions with young people and community members (19); key informant interviews (9), in-depth interviews with 15-24 year-olds (58) and providers (33). Interviews were analysed using thematic analysis. PrEP awareness increased from 2% to 9%. Among 965 AGYW sexually-active by 2018, 13.4% (95%CI 11.4%-15.7%) reported transactional sex and 10.6% (95%CI 8.85-12.7%) sex for money. Of the 194 YWSS, 21 were aware of PrEP, but none had used it. Youth were enthusiastic about PrEP as tool for HIV prevention; whilst older community members were cautious about a technology they had limited experience with but could benefit select groups. Teachers and healthcare providers were concerned that PrEP would lower personal responsibility for sexual health. In conclusion, the narrow and limited introduction of PrEP to YWSS reduced the accessibility and reach. Introducing PrEP as part of sexual healthcare may improve demand and access for YWSS.Three new sesquiterpenoid alkaloids, cangorin K (1), dimacroregelines C (2) and D (3), as well as two known sesquiterpenoids (4-5), were isolated from the roots of Tripterygium wilfordii Hook. f. The structures of new compounds were characterised by extensive 1D and 2D NMR spectroscopic analyses, as well as HRESIMS data, and the known compounds were established by 1 D NMR spectra referring to the literatures. Cytotoxicity evaluation of these compounds against two human tumour lines (SMMC7721, LN229) was investigated by CCK-8 assay and displayed that compounds 1-4 showed potent cytotoxicity against SMMC7721 cell with IC50 value in the range of 0.26-9.67 μΜ and compounds 1-5 showed potent cytotoxicity against LN-229 cell with IC50 values in the range of 0.50-7.38 μΜ.The 34th IUSTI European Conference was held from the 3rd to the 5th of October 2020. There were presentations on STIs in Europe, many centred on Romania. A full session was devoted to syphilis, including global efforts in syphilis vaccine development. A workshop on Pre-Exposure Prophylaxis (PrEP) implementation in Europe reviewed the 'PrEP gap' and the East/West divide with an additional presentation on upcoming PrEP technologies. The conference featured symposia from WHO STIs are still increasing and with no Euro universal surveillance systems. Other symposia focused on health inequalities amongst gender and sexual minorities and the recently published changes in IUSTI guidelines on gonorrhoea, syphilis and Lymphogranuloma Venere
