Polyploidization is thought to result in instant sympatric speciation, but several cases of hybrid zones between one of the parental species and its polyploid derivative have been documented. Previous work showed that diploid Sphagnum lescurii is an allopolyploid derived from the haploids S. lescurii (maternal progenitor) and S. subsecundum (paternal ...

Most microdeletion syndromes identified before the implementation of array-CGH were presumed to be well-defined clinical entities. However, the introduction of whole-genome screening led not only to the description of new syndromes, but also to the recognition of a broader spectrum of features for well-known syndromes. Here, we report on 10 ...

A new method for phase-shifting interferometry based on wave amplitude modulation is proposed and discussed. This proposal is based on the interference of three waves, where two waves attend as two reference waves and the other wave attends as a probe wave. Thereby, three interference terms are obtained, but because ...

Mitochondria are central organelles in cellular energy metabolism, apoptosis, and aging processes. A signaling network regulating these functions was recently shown to include soluble adenylyl cyclase as a local source of the second messenger cAMP in the mitochondrial matrix. However, a mitochondrial cAMP-degrading phosphodiesterase (PDE) necessary for switching off this ...

Factors associated with mineralization and osteophyte formation in osteoarthritis (OA) are incompletely understood. Genetic polymorphisms of matrix Gla protein (MGP), a mineralization inhibitor, have been associated clinically with conditions of abnormal calcification. We therefore evaluated the relationship of MGP concentrations and polymorphisms at the MGP locus to hand OA. Ours ...

Almost half of the world's population uses coal and biomass fuels for domestic energy. Limited evidence suggests that exposure to air pollutants from indoor biomass combustion may be associated with elevated blood pressure (BP). Our aim was to assess the relationship between air pollution exposure from indoor biomass combustion and ...

Ig gene hypermutation is initiated by the activation-induced cytidine deaminase (AID), which converts cytosine to uracil and generates a U:G lesion. One of the unsolved mysteries is how AID-triggered U:G lesions result in efficient induction of mutations at non-damaged A/T bases in the V(H) genes of germinal center (GC) B ...

Chlamydia trachomatis is an obligate intracellular bacterium that is dependent on its host cell for nucleotides. Chlamydia imports ribonucleotide triphosphates (NTPs) but not deoxyribonucleotide triphosphates (dNTPs) and instead uses ribonucleotide reductase to convert imported ribonucleotides into deoxyribonucleotides for DNA synthesis. The genes encoding ribonucleotide reductase have been recently shown to ...

The alternative sigma factor σ(B) of Staphylococcus aureus is involved in the coordination of the general stress response, expression of virulence determinants, and modulation of antibiotic resistance levels. It controls a large regulon, either directly by recognizing conserved σ(B) promoter sequences or indirectly via σ(B)-dependent elements. The σ(B)-controlled yabJ-spoVG operon ...
