Streptococcus pneumoniae is a member of the Mitis group of streptococci which, according to 16S rRNA-sequence based phylogenetic reconstruction, includes 12 species. While other species of this group are considered prototypes of commensal bacteria, S. pneumoniae is among the most frequent microbial killers worldwide. Population genetic analysis of 118 strains, supported by demonstration of a di...

Mesopolyploid whole-genome duplication (WGD) was revealed in the ancestry of Australian Brassicaceae species with diploid-like chromosome numbers (n = 4 to 6). Multicolor comparative chromosome painting was used to reconstruct complete cytogenetic maps of the cryptic ancient polyploids. Cytogenetic analysis showed that the karyotype of the Australian Camelineae species descended from the eight ...

Several illnesses cause suffering and pre-death grief among close relatives, as in cancer and dementia. This might be the case also at Parkinson’s Disease (PD). We aimed at getting grief self-reports of relatives of PD patients using the same instrument (AGS) as in former grief studies to see similarities and differences. Anticipatory Grief Scale (AGS) and questions about background variables w...

The paper describes various approaches to the invertibility of Toeplitz plus Hankel operators in Hardy and lp-spaces, integral difference Wiener-Hopf generalized operators. Special attention is paid a newly developed method, which allows establish necessary, sufficient also necessary conditions invertibility, one-sided for wide classes derive efficient formulas corresponding inverses. work cont...

Bacillus subtilis is considered a soil organism for which endospore formation provides a means to ensure long-term survival in the environment. We have addressed here the question of what happens to a spore when ingested. Spores displaying on their surface a heterologous antigen, tetanus toxin fragment C (TTFC), were shown to generate anti-TTFC responses not to the antigen contained in the prim...
