13. Misclassification Bias and the Estimated Effect of Parental Involvement Laws on Adolescents' Reproductive Outcomes
Objectives. We evaluated the presence of misclassification bias in the estimated effect of parental involvement laws on minors’ reproductive outcomes when subjection to such laws was measured by age at the time of pregnancy resolution.

14. Cyclophosphamide-Induced IN VIVO Sister Chromatid Exchanges (Sce) in MUS MUSCULUS. III. Quantitative Genetic Analysis
In vivo cyclophosphamide (CP)-induced sister chromatid exchanges (SCEs) were evaluated in females from five genetic strains of mice (C57BL/6J, C3H/S, 129/ReJ, BALB/c and DBA/2) and their F1 hybrids. Baseline (noninduced) SCE values differ significantly among strains, 129/ReJ having the lowest and DBA/2 having the highest mean SCE per cell values. In general,

15. Elimination of plasmid-linked polyglutamate production by Bacillus subtilis (natto) with acridine orange.
Treatment of Bacillus subtilis (natto) strains Asahikawa, F, and M with acridine orange resulted in the conversion of approximately 64.2% of the Asahikawa population, 22.4% of the F population, and 9.2% of the M population to polyglutamate-nonproducing colonies. Such curing is suggestive of the involvement of plasmid DNA. Samples of cleared lysates of both p

16. Familial infantile scoliosis associated with bilateral paralysis of conjugate gaze.
A family with two sibs suffering from idiopathic infantile scoliosis associated with bilateral paralysis of conjugate gaze is reported. Although the parental consanguinity and the involvement of patients of both sexes in this family are suggestive of an autosomal recessive mode of inheritance, a dominant or multifactorial pattern remains a possibility.

17. Alteration of Host Specificity to Lytic Bacteriophages in Streptococcus cremoris†
A mutant of Streptococcus cremoris strain ML1 was isolated based on its resistance to acriflavine. The mutant strain showed resistance to the growth of virulent bacteriophages to which the parental strain was sensitive whereas it became sensitive to a number of other virulent phages to which the parental strain was resistant. At the same time, infection of t

18. Recovery and Altered Neutralization Specificities of Chimeric Viruses Containing Capsid Protein Domain Exchanges from Antigenically Distinct Strains of Feline Calicivirus
Feline calicivirus (FCV) strains can show significant antigenic variation when tested for cross-reactivity with antisera produced against other FCV strains. Previous work has demonstrated the presence of hypervariable amino acid sequences in the capsid protein of FCV (designated regions C and E) that were postulated to constitute the major antigenic determin

19. Role of two particle types in bovine rotavirus morphogenesis.
The involvement of light (L) and dense (D) bovine rotavirus particle types during virus replication has been studied. It was found that infectious parental L virions are uncoated in vivo to a particle similar to native D particles. Differences in the rate of synthesis and relative yields of L and D particles in MDBK and MA-104 cells have been detected. Resul

20. Excision of micronuclear-specific DNA requires parental expression of Pdd2p andoccursindependentlyfromDNA replication in Tetrahymena thermophila
Elimination of germ-line DNA segments is an essential step in the somatic development of many organisms and in the terminal differentiation of several specialized cell types. In binuclear ciliates, including Tetrahymena thermophila, DNA elimination occurs during the conversion of the germ-line micronuclear genome into the somatic genome of the new macronucle

21. Distal monosomy 14 not associated with ring formation.
A 12-year-old boy with congenital heart disease, short stature, mildly dysmorphic facies, and mild intellectual impairment was found to have a de novo terminal deletion (14)(q32.3). Although his phenotype resembles that of six reported patients with a similar breakpoint, his CNS involvement is milder. He appears to be the first reported case of a terminal de

22. Bilateral striatal necrosis, dystonia and optic atrophy in two siblings.
Two siblings developed a neurological disorder in the first decade characterised by generalised dystonia, hypokinesia, and subacute visual loss. CT and serial MRI examinations showed bilateral lesions of the striatum, mainly in the putamen. The classification of these patients is discussed in relation to infantile bilateral striatal necrosis (IBSN), Leigh's

23. Linkage of Niemann-Pick disease type C to human chromosome 18.
We analyzed the involvement of chromosome 18 in Niemann-Pick disease type C (NPC), an autosomal recessive cholesterol-processing disorder. Within affected offspring, the chromosome 18 parental contributions were identified by using allele-specific microsatellite markers. Significant linkage of NPC to an 18p genomic marker, D18S40, was indicated by a two-poin

24. Multiple nutritional requirements of lactobacilli: genetic lesions affecting amino acid biosynthetic pathways.
Genetic lesions responsible for amino acid requirements in several species of multiple auxotrophic lactobacilli were investigated. Systematic attempts were made to isolate mutants that could grow in the absence of each of the amino acids required by the parental strains of Lactobacillus plantarum, L. casei, L. helveticus, and L. acidophilus. After treatment
