Age-related changes in serological susceptibility patterns to measles

Association of Apolipoprotein E Alleles with Susceptibility to Age-Related Macular Degeneration in Iranian Patients

Background: We aimed here to investigate the association between alleles and genotypes of APOE and Age-related macular degeneration (AMD) development. Materials and Methods: After ophthalmological examination, 120 patients with confirmed AMD and 120 healthy controls were enrolled in the study. The polymorphic segment of APOE gene was PCR-amplified and sequenced to determine the frequency distr...

Serological Epidemiology in Measles **

One usually thinks of measles as a minor childhood illness through which we all must pass and as a nuisance more than a danger. But this was not always the case. In colonial America, two hundred years ago, measles was dreaded like the plague, and today in remote parts of the world, on isolated islands and in the Arctic, it can be a devastating disease.

Age-related changes in sleep/wake patterns among Korean teenagers.

INTRODUCTION As children go through the transition from childhood to adolescence, many shifts occur in sleep/wake patterns related to intrinsic and extrinsic developmental changes. These shifts have been shown to result in corresponding shifts in sleep phase (later sleep onset) and sleep deprivation among teenagers in Western societies. However, the effect of these developmental changes on the ...

Serological response to early measles vaccination.

This study compares the persistence of measles IgG antibody in 239 children vaccinated at 6-8 months of age with 76 children vaccinated after 8 months of age. Among the children vaccinated prior to 9 months, 49 per cent of the children between 16 and 44 months and 33 per cent of children over 54 months had levels of measles IgG antibody conventionally considered protective. Among the children o...
