Purification of periplasmic flagellar antigen from Borrelia microtti.

Borrelia microtti and Borrelia persica are 2 Iranian strains of Borrelia found in western Asia and responsible for relapsing fever. The outer surface antigens of Borrelia undergo variations which are responsible for the relapsing phenomenon. The fixed flagellar antigen is required for diagnosis as the variant antigens cannot be used in serological methods of diagnosis. The fixed flagellar antigen was purified for the first time from the Iranian strain of Borrelia microtti using detergent treatment and shearing in an omnimixer. Periplasmic flagella were extracted, as confirmed by electron microscopy. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis revealed a band corresponding to 42 kDa. Indirect haemagglutination kits were designed using the pure flagella and the complete sonicate of Borrelia and showed 98% sensitivity and 95% specificity.

The outflow of minorities from the post-Soviet state: the case of Kazakhstan.

The author examines the flow of the non-Kazakh population from the territory of Kazakhstan since the country became independent in December 1991. "This study [analyzes] the ongoing migration process from...a Kazakh point-of-view--meaning, not from the position of a Kazakh ¿nationalist' but from a pragmatic stance, taking into consideration the specific elements of the situation in the country. In particular, it is suggested that the ¿nationalist' interpretation (which is not actively promoted in the country's internal politics, by the way) is less than ideal as a scientific explanation of this migration, and various other contributing factors will be presented."

Breast-feeding patterns in Saudi Arabia.

A survey was conducted on 1019 mothers in 79 primary health care centers in Saudi Arabia to determine the patterns of breast feeding. A large percentage of mothers (98%) had breastfed their infants at birth. This rate dropped to 96.5% during the first week of life. There were 635 (64.1%) mothers who started to breastfeed their babies within 6 hours of delivery. Over two-thirds (68.9%) of mothers gave supplemental liquids to infants during the first 3 days of their life. More than half fed their infants on demand rather than on schedule. A high proportion (94.4%) breastfed at night, with 88.1% feeding their infants more than once. There was no significant relationship between the duration of suckling and the mother's age or work status (p 0.05). However, a significant relationship (p 0.001) was found between the duration of suckling and the mother's literacy. More than three-quarters of mothers slept in the same bed with their infants or in the same room. A large percentage of women initiated breast feeding; however, many introduced a supplement too early, a practice that should be discouraged.

Anticipating demographic superiority: Kazakh thinking on integration and nation building.

"In order to understand and to forecast what kind of nations will take shape in the new states of the former Soviet Union it is important to focus on the express objectives and actual strategies of the nation builders.... In this article I will concentrate on the ideological aspect, that is, on official and semi-official statements outlining the idea of ¿the Kazakhstani nation', as Kazakhstani nation builders would like to see it develop." Particular attention is given to the changes in the ethnic composition of the country due primarily to the different demographic characteristics of the main ethnic groups that make up the population, the ethnic Kazakhs and Russians, and to the political implications of the growth of the Kazakhs from a minority to a majority ethnic group.

The effect of housing construction on population migrations in Israel.

"Population migrations in Israel simultaneously move in two opposite directions: while the initial distribution of new immigrants is primarily focused on big cities of the country's central core, the existing population of these centres tends to move outward, to small settlements where housing is more readily available. The effect of housing construction on population migrations appears to be delayed and tends to become visible with the passage of time. The initial low attractiveness of urban settlements in peripheral districts of the country to the new immigrants is mainly caused by [the] small size of the population in the settlements and an inferior state of urban development rather than by a lack of new housing or the harsh climatic conditions of these areas."
