Features of the course of the gestational process with the carriage of genotypes F5L:G(1961)A and F2:G(20210)A and inheritance options

Aim of the study – to establish the features of inheritance of the F5L:G(1961)A and F2:G(20210)A genotypes and to assess their influence on the course and outcomes of pregnancy.Materials and methods. The object of the study was 70 mother–child pairs: 50 women, carriers of the F5L:G(1961)A mutation, and their children; 20 female patients, carriers of the F2:G(20210)A mutation, their children. Additionally, 18 families of women, carriers of the factor V Leiden mutation, in three generations were studied.Results. Carriage of the F5:(1961)GA and F2:(20210)GA genotypes in fetuses is associated with the risk of developing gestational complications in their mothers, which are primarily realized when the maternal laboratory phenotype is manifested. A higher frequency of occurrence of the minor allele A20210 of the FII gene was determined in children than in the older generation (p = 0,0006).

Tweed Structure

Natural Amelia albite (Ab99.3An0.1Or0.6) annealed at 1073° and 924°C for various periods up to 140 days has been studied by NMR. TEM studies of the same sample revealed a distinct tweed microstructure in some samples annealed at both 1073°C and 924°C. On the whole, the quasi-regular tweed has a periodicity of 100 - 200 Å in both directions, one nearly normal to b* and the other approximately parallel to b*, which gives rise to two-directional streaking in SADP’s (Fig. 1 and 2). However, there are some differences in the tweed structure developed on annealing at 1073°C and at 924°C in albite.Albite samples annealed at 1073° show a systematic trend in their development of tweed structures: the regularity, periodicity, and frequency of occurrence increase with annealing time during the first 3 days, and then decrease gradually until no tweed microstructures are seen in samples annealed for more than 15 days. The tweed structure proceeds locally to form one-directional twin-like microstructures.

Frequency Of Occurrence

This study examines the assumptions underlying the scoring system of the Arizona Articulation Proficiency Scale: Revised. Twenty-one children between the ages of four years two months and six years 11 months were administered the Arizona Articulation Proficiency Scale: Revised and the Screening Deep Test of Articulation. The subjects' performance on the two tests was compared for the phones: [s], [l], [r], [t∫], [θ], [∫], [k], [f], and [t]. Results suggested that 1) the production of most sounds in only two contexts does not necessarily reflect the accuracy of production of those sounds in other contexts, and 2) for the sounds tested, the weightings assigned on the basis of their frequency of occurrence rather than the frequency with which they were misarticulated overestimated the extent of many articulation errors.

Classroom teachers were asked to list the traits they felt were characteristic of the elementary school child who wears a hearing aid. These listings were evaluated according to the desirability of the traits and were studied regarding frequency of occurrence, desirability, and educational, emotional, and social implications. The results of the groupings are discussed in terms of pre-service and in-service training.
