Malaria is one of the leading public health problems worldwide, with incidence estimated at 219 million and deaths reported at approximately 660,000 in 2010 [1]. Almost 90% of these deaths occur in sub-Saharan Africa (SSA), of which 91% are in children under five. Young children are most susceptible to malaria due to waning of their passive immunity and an acquired immunity that has not fully d...
Hyperimmune globulins were reported to prevent and treat fetal cytomegalovirus (CMV) infection during pregnancy. Here, we report that infusions of standard human intravenous immunoglobulin significantly increase CMV IgG titers and avidity indexes in pregnant women, paving the way to their use for passive transfer of maternal CMV humoral immunity to fetuses. Preliminary data on perinatal outcome...
QUESTION What is the basis for the new recommendations to vaccinate pregnant women against pertussis after the first trimester? ANSWER There have been outbreaks of epidemic proportions of pertussis, mostly among young infants who have not received sufficient passive immunity from their mothers. This strategy of vaccination during pregnancy aims at stopping these life-threatening epidemics.
Passive transfer of humoral immunity to experimental syphilis in rabbits was accomplished with large doses of hyperimmune serum. When the serum was administered before inoculation of Treponema pallidum, the onset of chancres was delayed; when it was given early in the course of infection, a transient period of arrest and healing of the chancres was imposed.
1. Azoproteins containing structurally isomeric aldobionic acids evoke in rabbits antibodies which are both serologically and immunologically specific. 2. Antigens containing the azobenzyl glycosides of the synthetic gentio-biuronic and glucuronic acids evoke in rabbits antibodies which confer passive immunity on mice against infection with multiple lethal doses of virulent Type II pneumococci.
پیاده سازی تئوری تغییرشکل های یکنواخت در کنترل نیمه فعال سازه ها با استفاد ه از کنترل کننده های فازی
در این مطالعه هدف پیاده سازی یک سیستم کنترلی فازی بر مبنای تئوری تغییرشکل های یکنواخت برای کنترل نیمه فعال سازه های مجهز به میراگر با استفاده از الگوریتم بهینه یابی pso تحت بارهای لرزه ای است. در این پژوهش کارایی ایده ی یکنواخت کردن دریفت ها در کاهش پاسخ های لرزه ای سازه مورد بررسی قرار گرفته است. برای بررسی توانمندی استراتژی پیشنهادی برای سازه های مختلف و ارتعاشات لرزه ای متفاوت، شبیه سازی عدد...
Vaccination with J8-DT, a leading GAS vaccine candidate, results in protective immunity in mice. Analysis of immunologic correlates of protection indicated a role of J8-specific antibodies that were induced post-immunization. In the present study, several independent experimental approaches were employed to investigate the protective immunological mechanisms involved in J8-DT-mediated immunity....
