- Synthetic oligodeoxyribonucleotides were used for type-specific identification of members of the coxsackie B virus group by nucleic acid hybridization. Two pairs of oligonucleotide chains were constructed based on nucleotide sequences in the VP1 regions of coxsackieviruses B3 and B4. Each labelled probe had a length of 24 nucleotides. The results showed that the oligonucleotide hybridized in a type-specific manner when assayed with extracts from cells infected with all different coxsackie B viruses. A method based on similar principles may thus be used for enterovirus typing.

- The entire nucleotide sequence of the coxsackievirus B3 strain Nancy (CB3) genome has been determined from cDNA. The genome is 7396 nucleotides long, and encodes a 2185 amino acid long polyprotein. It exhibits the same gene organization as other enterovirus genomes. A detailed comparison was carried out between the proteins encoded by the CB3 and poliovirus type 1 strain Mahoney (PVI) genomes. The genes encoding the VPg polypeptide and the viral polymerase are the most conserved regions. The structural polypeptides VP1, VP2, and VP3 are less well conserved although proline and tryptophan residues frequently are found in identical positions. The VP1 protein of CB3 shows a particularly limited homology in those regions which have been found to induce neutralizing antibodies against PV1. The 5′ noncoding region of CB3 is closely related to that of PV1, with regard to both length and sequence organization, whereas the 3′ noncoding region of CB3 exhibits some unique features.

- presentation: An abstract, including parts of the results, has been presented at an oral session at the European Respiratory Society International Conference, London, UK, September 2016. Background: Cardiovascular comorbidity contributes to increased mortality among subjects with COPD. However, the prognostic value of ECG abnormalities in COPD has rarely been studied in population-based surveys. Aim: To assess the impact of ischemic ECG abnormalities (I-ECG) on mortality among individuals with COPD, compared to subjects with normal lung function (NLF), in a population-based study. Methods: During 2002-2004, all subjects with FEV1/VC<0.70 (COPD, n=993) were identified from population-based cohorts, together with age- and sex-matched referents without COPD. Re-examination in 2005 included interview, spirometry, and 12-lead ECG in COPD (n=635) and referents [n=991, whereof 786 had NLF]. All ECGs were Minnesota-coded. Mortality data were collected until December 31, 2010. Results: I-ECG was equally common in COPD and NLF. The 5-year cumulative mortality was higher among subjects with I-ECG in both groups (29.6% vs 10.6%, P<0.001 and 17.1% vs 6.6%, P<0.001). COPD, but not NLF, with I-ECG had increased risk for death assessed as the mortality risk ratio [95% confidence interval (CI)] when compared with NLF without I-ECG, 2.36 (1.45-3.85) and 1.65 (0.94-2.90) when adjusted for common confounders. When analyzed separately among the COPD cohort, the increased risk for death associated with I-ECG persisted after adjustment for FEV1 % predicted, 1.89 (1.20-2.99). A majority of those with I-ECG had no previously reported heart disease (74.2% in NLF and 67.3% in COPD) and the pattern was similar among them. Conclusion: I-ECG was associated with an increased risk for death in COPD, independent of common confounders and disease severity. I-ECG was of prognostic value also among those without previously known heart disease.

- The aim of this meta-analysis, based on individual participant data from several studies, was to investigate the influence of patient-, materials-, and tooth-related variables on the survival of posterior resin composite restorations. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a search resulting in 12 longitudinal studies of direct posterior resin composite restorations with at least 5 years' follow-up. Original datasets were still available, including placement/failure/censoring of restorations, restored surfaces, materials used, reasons for clinical failure, and caries-risk status. A database including all restorations was constructed, and a multivariate Cox regression method was used to analyze variables of interest [patient (age; gender; caries-risk status), jaw (upper; lower), number of restored surfaces, resin composite and adhesive materials, and use of glass-ionomer cement as base/liner (present or absent)]. The hazard ratios with respective 95% confidence intervals were determined, and annual failure rates were calculated for subgroups. Of all restorations, 2,816 (2,585 Class II and 231 Class I) were included in the analysis, of which 569 failed during the observation period. Main reasons for failure were caries and fracture. The regression analyses showed a significantly higher risk of failure for restorations in high-caries-risk individuals and those with a higher number of restored surfaces.

- A cDNA copy covering two-thirds of the coxsackievirus B3 genomewas cloned in the PstI site of the pBR322 vector. A nucleotidesequence containing the gene for the viral replicase and the3' noncoding region of the coxsackievirus B3 genome was determined.The predicted amino acid sequence of the coxsackievirus B3 replicasewas shown to be remarkably similar to that of the poliovirus1 replicase. The 3' noncoding region, in contrast, was onlyweakly homologous to the poliovirus 1 sequence but showed aclose relationship to the sequence of swine vesicular diseasevirus, a variant of coxsackievirus B5. A 13-nucleotide-longsegment located near the polyadenylic acid junction is conservedin several members of the enterovirus group and may thus servean important function during replication of viral RNA.
