All cross-sectional studies concerning prevalence of chronic hepatitis B infection in Iran were included irrespective of date and language. The outcome of interest was prevalence of chronic hepatitis B infection confirmed by blood specimen positive for HBsAg. The prevalence of

chronic hepatitis B infection was estimated about 1.7% or lower in general population; 0.8% (95% CI: 0.6% to 0.9%) in blood donors and 3.2% (95% CI: 2.3% to 4.1%) in intravenous drug users and varied from zero to 1.5% in beta thalassemic patients. Since mass vaccination in 1993, prevalence of chronic hepatitis B infection has being reduced among children and adolescents. This reduction 4EGI-1 ic50 call be attributed to the effectiveness of the national immunization program and it may impact on reduction of prevalence

of hepatitis B infection in general population.”
“BACKGROUND AND OBJECTIVES: Previous studies that have assessed patient awareness of the management of sickle cell disease (SCD) indicated a lack of awareness of the disease and possibly a need for more public education. Therefore, we measured public awareness in Bahrain of SCD.\n\nMETHODS: The study was conducted from December 2006 to February 2007. A questionnaire was distributed among 2000 persons selected from among the general public. The participants had face-to-face interviews with either a health professional or a trained interviewer.\n\nRESULTS: Most (93%) had heard of SCD and 89% knew that it can be diagnosed by a blood test, but 51% did not selleck products know the prevalence of SCD in Bahrain. Eighty-four percent recognized it as a hereditary disorder and 72% said that it can skip generations. Females showed AZD9291 molecular weight better knowledge than

males and married persons seems to know more about SCD than unmarried ones.\n\nCONCLUSION: There is a good level of knowledge about SCD among the public, though some of the respondents were confused about the difference between the carrier state of a disease and the disease itself. There is wide acceptance and appreciation of the SCD prevention campaigns being conducted in Bahrain, such as the premarital service and the student screening program.”
“A method of ion-beam-induced reduction in oxides is used to produce metal-bismuth nanowires embedded into a matrix of a highly insulating dielectric-bismuth oxide. The metal film is formed in the process of reduction of the metal oxide by selective removal of oxygen atoms under irradiation by the beam of protons through a mask. The mask containing pairs of parallel nanowires with contact pads was fabricated using 50 kV electron-beam lithography in a single layer of 200-nm-thick ZEP-520 (Zeon Chemicals L. P., ZEP-520 electron-beam resist) electron-beam resist. Electrical properties of the fabricated nanowires have been studied.
