Women of reproductive age are mostly affected and infected with the HIV disease. Methodology: A cross-sectional study of 216 randomly selected women that booked for antenatal care at the Faith Alive Foundation and PMTCT centre Jos between 1st July to 31st December, 2014 was carried out. Information regarding age, parity, gestational age at booking, educational status and HIV sero-status of the clients was analysed. Screening test was conducted in a serial two step approval using determine and UNIGOLD as the confirmatory test, while STAT-PAK was the tie-beaker with discordant result as per the national algorithm. Positive samples were confirmed by western blot method. Result: A total of 18 women out of the 216 women studied were positive giving a sero-prevalence rate of 8.3%. The highest sero-prevalent rate was amongst 25 - 29 years age group (31.5%). Women of parity 1 - 4 constituted the highest group of 62.9%. Majority of the women 65.7% booked in the second trimester while 26.9% booked in the 3rd trimester. Most of the women 47.2% had secondary school education while only 5.6% of them had no form of education. Conclusion: HIV infection prevalence rate among antenatal attendants at Faith Alive Foundation and PMTCT centre Jos is still high. Multisectorial approach and intervention strategies should be further scaled up for the prevention of vertical transmission of the virus. However, it is worth noting that it is mainly an HIV/AIDS hospital which should have affected the outcome.展开更多

However, changes in the functional connectivity between the defauk mode network and insula during pain remain unclear. This study used 3.0 T functional magnetic resonance imaging scans in 12 healthy sub- jects aged 24.8 ± 3.3 years to compare the differences in the functional activity and connectivity of the insula and default mode network between the baseline and pain condition induced by intramuscular injection of hypertonic saline. Compared with the baseline, the insula was more functionally connected with the medial prefrontal and lateral temporal cortices, whereas there was lower connectivity with the posterior cingulate cortex, precuneus and inferior parietal lobule in the pain condition. In addition, compared with baseline, the anterior cingulate cortex exhibited greater connectivity with the posterior insula, but lower connectivity with the anterior insula, during the pain condition. These data indicate that experimental low back pain led to dysfunction in the connectivity between the insula and default mode network resulting from an impairment of the regions of the brain related to cognition and emotion, suggesting the impor- tance of the interaction between these regions in pain processing.展开更多

The concepts of min and minben are much in line with their contemporary counterparts of "human" and "people orientation". Upholding the belief of "people as the foundation of states", minben advocates the fundamental political status of the people, and requires leaders to implement "people-oriented" policies. Its encapsulation of the theoretical foundation and basic requirements for the protection of human rights enabled it to promote the protection of people’s livelihoods and civil rights in ancient China. Its sublimation in contemporary China has had, and will continue to have, a far-reaching impact on the development of human rights in China.展开更多

The Chinese government has exerted great efforts to promote women’s education and to remove barriers to female education. In regular education, the state has adopted measures to increase the proportion of female enrollment. In some remote, poverty-stricken areas and ethnic minority areas, there are free courses and schools specially for women as a measure. In 1992, the attendance rate for girls from 7 to 11 years old had risen to 96.2 percent from less than 20 percent before the founding of the People’s Republic of China in 1949. The proportion of females in middle schools, colleges and postgraduate schools reached 43.1 percent, 33.7 percent展开更多
