In recent years, emerging structural information on the aRNAP (archaeal RNA polymerase) apparatus has shown its strong evolutionary relationship with the eukaryotic counterpart, RNA Pol (polymerase) II. A novel atomic model of SshRNAP (Sulfolobus shibatae RNAP) in complex with dsDNA (double-stranded DNA) constitutes a new piece of information helping the ...

Bipartition distraction is a novel procedure combining frontofacial bipartition and monobloc distraction. Apert syndrome and other syndromic craniofacial dysostoses are often characterized by hypertelorism, with a negative canthal axis and counterrotated orbits. Central midface hypoplasia can result in a biconcave face in both midsagittal and axial planes. Bipartition distraction can ...

Several species of haloarchaea have been shown to be polyploid and thus this trait might be typical for and widespread in haloarchaea. In the present paper, nine different possible evolutionary advantages of polyploidy for haloarchaea are discussed, including low mutation rate, radiation/desiccation resistance, gene redundancy and survival over geological times ...

INTRODUCTION. Carotid stenosis is a complication of cervical radiotherapy. In these cases carotid angioplasty has been considered as the elective revascularisation treatment. Yet, the indication to treat is under discussion due to the high rate of restenosis and the scarcity of studies conducted on the long-term development. AIMS. To report ...

Several QTLs for cell wall degradability and lignin content were previously detected in the F288 × F271 maize RIL progeny, including a set of major QTLs located in bin 6.06. Unexpectedly, allelic sequencing of genes located around the bin 6.06 QTL positions revealed a monomorphous region, suggesting that these QTLs were likely ...

BACKGROUND: Early detection of metastases in muscle-invasive bladder cancer is crucial. Current imaging techniques provide only limited sensitivity for the detection of low volume metastases. Molecular markers and new rapid analysis techniques are therefore needed to improve metastasis detection sensitivity. High urinary matrix metalloproteinase 7 (MMP 7) levels were previously shown ...

A five-year-old girl, vaccinated against varicella-zoster virus (VZV) presented with clinical symptoms of herpes zoster in the 6th cervical dermatome. A VZV direct immune-fluorescence assay was negative three times but additional genotypical analysis showed a VZV strain genotype 2 (Oka vaccine strain). Therefore the diagnosis of a breakthrough varicella disease ...

Nonhost resistance (NHR) of plants to fungal pathogens comprises different defense layers. Epidermal penetration resistance of Arabidopsis to Phakopsora pachyrhizi requires functional PEN1, PEN2 and PEN3 genes, whereas post-invasion resistance in the mesophyll depends on the combined functionality of PEN2, PAD4 and SAG101. Other genetic components of Arabidopsis post-invasion mesophyll ...
