The intraocular pressure response to topical betamethasone appears to be genetically determined. A study of patients with primary open-angle glaucoma, their relatives, glaucoma suspects, and volunteers shows three populations as to degree of responsiveness. It is suggested that these are the phenotypes which relate to the homozygous poor responder (nn), the heterozygous responder (ng), and the ...

background and objective: brucellosis is a zoonotic disease of worldwide distribution and has great economic importance. despite its control in many countries, it remains endemic in iran. brucellosis was investigated in many high risk occupational groups; however, few studies on the prevalence of brucellosis among blood donors are available. to determine the seroprevalence of brucellosis antibo...

This draft specifies a modification to RFC 3168 to allow TCP SYN/ACK packets to be ECN-Capable. For TCP, RFC 3168 only specifies setting an ECN-Capable codepoint on data packets, and not on SYN and SYN/ACK packets. However, because of the high cost to the TCP transfer of having a SYN/ACK packet dropped, with the resulting retransmit timeout, this document specifies the use of ECN for the SYN/AC...

Primary human immunodeficiency virus (HIV) infection is controlled principally by HIV-specific cytotoxic T lymphocytes (CTL) to a steady-state level of virus load, which strongly influences the ultimate rate of progression to disease. Epitope selection by CTL may be an important determinant of the degree of immune control over the virus. This report describes the CTL responses of two HLA-identi...

The development of IgG L-glutamic Acid60-L-alanine30-L-tyrosine10 (GAT)-specific plaque-forming cell responses in vitro by virgin and immune (responder X nonresponder)F1 spleen cells after stimulation with responder and nonresponder parental GAT-macrophages (Mphi) was investigated. Virgin F1 spleen cells developed comparable primary responses to both parental GAT-Mphi. By contrast, F1 spleen ce...

background: hepatitis a virus (hav) is a single strand and non-enveloped rna virus. it is usually transmitted by the fe­cal-oral and the blood transfusion routes and causes the hepatitis a disease. clinically, the hepatitis a is usually mild, par­ticularly in children, in whom it is frequently subclinical. the disease is more serious and prolonged in adults. the objective of this study was to f...

background : to analyze serologic markers of hepatitis g virus (gbv-c) infection in iranian blood donors and two major groups of multitransfused patients, hemophiliacs and thalassemics. methods :nine hundred and five serum samples collected from the volunteer blood donors and two patient groups under the study were tested for the presence of antibodies to the gbv-c antigen (anti e2 ) by an elis...
