Abstract
The operation of an intracavity frequency shifted feedback (FSF) laser exhibits a remarkable range of properties, some of which have been described previously. Here we report a more complete analysis of the dependence of the output power upon pump-laser power, based on simulations with an extended rate equation model and the use of phase space analysis. The effect of FSF is discussed in detail. The simulation of the operation of a titanium-sapphire laser with FSF reveals five separate regimes of operation, a superset of those observed in experiment. We predict the thresholds for each of these regimes for FSF-lasers with titanium-sapphire or neodymium doped crystals as gain medium.

Abstract
The transgenic sequences in the mouse line TKZ751 are demethylated on a DBA/2 inbred strain background but become highly methylated at postimplantation stages in offspring of a cross with a BALB/c female. In the reciprocal cross the transgene remains demethylated suggesting that imprinted BALB/c methylation modifiers or egg cytoplasmic factors are responsible for this striking maternal effect on de novo methylation. Reciprocal pronuclear transplantation experiments were carried out to distinguish between these mechanisms. The results indicate that a maternally-derived oocyte cytoplasmic factor from BALB/c marks the TKZ751 sequences at fertilization; this mark and postzygotic BALB/c modifiers are both required for de novo methylation of the target sequences at postimplantation stages. Using genetic linkage analyses we mapped the maternal effect to a locus on chromosome 17. Moreover, seven postzygotic modifier loci were identified that increase the postimplantation level of methylation. Analysis of interactions between the maternal and the postzygotic loci shows that both are needed for de novo methylation in the offspring. The combined experiments thus reveal a novel epigenetic marking process at fertilization which targets DNA for later methylation in the foetus. The most significant consequence is that the genotype of the mother can influence the epigenotype of the offspring by this marking process. A number of parental and imprinting effects may be explained by this epigenetic marking.

Abstract
Inherited factor VII (FVII) deficiency is a rare autosomal recessive disorder. Mutations and polymorphisms of the FVII gene were characterized in more than 40 unrelated patients with FVII deficiency. Among the 29 different mutations, the most frequent were Ala294 Val, Ala294Val;404delC, IVS7+7, and Val281 Phe. Four novel mutations (IVS2+1G>C, Arg247 Cys, Glu265 Lys, Asp343 His) were detected. The relationships between genotypes of mutations and polymorphisms of the FVII gene, FVII deficiency, and clinical phenotype were investigated. Homozygosity of the Phe4 Leu, IVS4+1G>A, Cys135 Arg, Ala244 Val, and Ala294 Val;404delC and the double heterozygosity of Tyr68 Cys / IVS3-1G>A, Val252 Met / IVS2+5G>T, Val281 Phe / Cys135 Arg, Ala294 Val / Val281 Phe, Ala294 Val;404delC / Val281Phe, Ala294 Val;404delC / Arg152 stop, Ala294Val;404delC / Gln(-35) stop, Ala294 Val / Val252 Met, Ala294 Val / Gly156 Asp, and Thr359 Met / Asp242 His were related to clinical symptoms. Double heterozygotes for Arg247 Cys / IVS2+1G>C, Ala206 Thr / Pro303 Arg, Leu(-20) Pro / Val252 Met as well as IVS7+7 /Ala294 Val, IVS7+7 /Ala206 Thr, and IVS7+7 / Met298 Ile were asymptomatic. The clinical symptomatology is rather poor in correlation with the FVII activity. Concerning the clinical phanotype, a correlation seems to exist between specific mutations and clinical symptoms.
