Approximately 9.6% of infants are premature and they can be at risk for hospitalization. This study has done for evaluation of awareness and knowledge of parents about problems of premature infants in Neonatal Intensive Care Unit (NICU). This was a descriptive study with 160 parents whose premature infants were admitted to NICU (Tehran-Iran, 2009-2011). Data were collected by a questionnaire for evaluation of awareness and knowledge of parents about problems of prematurity, and then analyzed by using descriptive analytic statistical methods and SPSS software. Based on the results, there was a significant relation between age and the total score of questionnaire (P = 0.022, R = 0.18). Mothers had higher awareness and knowledge than fathers (P < 0.05). The most awareness in parents was about doing of hygienic principle when they entered to NICU and about the importance of regularly and continuous attendance in ward. Awareness and knowledge of parents about problems of their premature infant were related to their age and being a mother or father. Parents had little knowledge about some NICU principles and premature infant’s needs and care.展开更多

In the present study, the wild-type HIV-1 genome was segregated into four plasmids, and an optimized novel HIV-1 lentiviral vector containing green fluorescent protein and vesicular stomatitis virus G pseudo-capsule was constructed. The plasmids were pHR-CMV-EGFP, pCMVΔ8.9, pRSV-Rev, pCMV-VSV-G. The four plasmid system was co-transfected into 293T cells, and green fluorescent protein expression was observed. The present study obtained lentiviral particles by high-speed centrifugation, and the lentiviral particle titer was 4 × 108 TU/mL after centrifugation. Thus, an optimized novel HIV-1 lentiviral vector was successfully constructed.展开更多
