Aim: To investigate the prevalence of high levels of sperm DNA damage among men from infertile couples with both normal and abnormal standard semen parameters. Methods: A total of 350 men from infertile couples were assessed. Standard semen analysis and sperm chromatin structure assay (SCSA) were carried out. Results: Ninety-seven men (28% of the whole study group) had a DNA fragmentation index (D
To detect effects of Cu pollution, the Cu tolerance of soil bacterial communities extracted from several vineyards located in NW Spain was measured. Bacterial community tolerance was estimated by means of the thymidine (TdR) and leucine (Leu) incorporation techniques using either IC50 values (the log of the metal concentration that reduced incorporation to 50%) or the percentage of activity at one
The study of sexually antagonistic (SA) traits remains largely limited to dioecious (separate sex), mobile animals. However, the occurrence of sexual conflict is restricted neither by breeding system (the mode of sexual reproduction, e. g. dioecy or hermaphroditism) nor by sessility. Here, we synthesize how variation in breeding system can affect the evolution and expression of intra- and inter-lo
Risk minimization is no longer a sufficient survival strategy for poor people in livelihood systems increasingly exposed to frequent extreme events. This calls for comprehensive adaptation to climate change. Within the climate change regime, adaptation is as central as mitigation but needs to be much more explicitly addressed at local, national and global levels. There is also a need for policy re
Multiple cardiac rhabdomyomas are frequently associated with tuberous sclerosis. However, very few cardiac malformations have been described with tuberous sclerosis. We report an unusual case of tuberous sclerosis with cerebral and renal lesions associated with dextrotransposition of the great arteries, pulmonary atresia, patent ductus arteriosus, multiple ventricular septal defects, and parachute
In order to evaluate three common human papillomavirus (HPV) DNA tests for key performance indices in population-based cervical screening, we sampled 12,527 women aged 3238 years who attended invitational, population-based screening and followed them for 4 years with comprehensive registry linkages. Three different HPV DNA tests (GP5+/6+general primer PCR (using either AmpliTaq or AmpliTaq Gold DN
A modification of the constrained geometry optimization method by Anglada and Bofill (Anglada, J. M.; Bofill, J. M. J. Comput. Chem. 1997, 18, 992-1003) is designed and implemented. The changes include the choice of projection, quasi-line-search, and the use of a Rational Function optimization approach rather than a reduced-restricted-quasi-Newton-Raphson method in the optimization step. Furthermo
Object-oriented classification approaches offer an alternative to per-pixel methods for assessment of land use and land cover. Combining object-oriented approaches with very high resolution imagery may provide enhanced possibilities for applications requiring land use and land cover data. The aim of this study is to evaluate the application of object-oriented classification of panchromatic very hi
This study maps reactions activated in peacekeeping personnel by life-threatening situations and explores how these reactions affect psychological functioning. In-depth interviews were carried out with 30 informants from the Swedish peacekeeping force serving in Bosnia between 1993 and 1995. All participants had experienced shooting incidents or other highly threatening events. Two models were for
The progeny of spontaneous interspecific hybrid sporophytes of Sphagnum were used to analyse the inheritance of cytoplasmic DNA. The analysis showed that only the female parent donated chloroplasts and mitochondria in Sphagnum hybrids. Thus, this is the first study demonstrating maternal cytoplasmic inheritance in a nonvascular land plant. This finding has important implications for phylogenetic r
We report a case of a patient who suffered generalized urticaria, chest tightness, wheezing, nausea, vomiting, hypotension, and loss of consciousness. Two hours earlier she had taken Eulitop Retard following lunch. She had tolerated all the implicated food after the reaction. Allergy evaluation revealed intense positive responses to intradermal tests with bezafibrate active component and Eulitop R
Neurohormonal changes in congestive heart failure (CHF) include an enhanced peripheral sympathetic nerve activity which results in increased release of noradrenaline, neuropeptide Y and ATP. To examine if such changes in CHF would modulate peripheral pre- and postsynaptic receptors of ATP and its degradation product adenosine, experiments were performed in a rat model of ischaemic CHF. In this mod
The hydrophobic contributions of 17 individual peptides, fused to the N-terminal of Bacillus stearothermophilus lactate dehydrogenase (LDH) were studied by hydrophobic interaction chromatography (HIC) and aqueous two-phase system (ATPS). The constructs were sequenced from a protein library designed with a five-amino acid randomised region in the N-terminal of an LDH protein. The 17 LDH variants an
Objective: Two patients who suffered acute failure of their St Jude Medical Masters aortic valve prostheses due to leaflet arrest that were unrelated to suture material are presented. It was hypothesized that the valves failed because force applied to bear upon the valve annulus caused the hinge mechanism to become restricted or to arrest. Methods: A study was designed to measure the force that wo
Abundant shale fragments were observed in dolerite material used for railway construction in western Skane, due to quarrying of Permo-Carboniferous dolerite in contact with Silurian shale (the Colonus Shale) in the Ronnarp Quarry, western Skane. Shale fragments were particularly enriched in the finest fractions of the crushed rock material. We analysed the clay mineralogy of shale from the railway
Objectives: To compare the pharmacodynamic effects of a pharmacokinetically enhanced formulation of amoxicillin 2000 mg twice daily, with amoxicillin 875 mg twice daily, 875 mg three times daily and 500 mg three times daily against Streptococcus pneumoniae with different susceptibility to amoxicillin in an in vitro kinetic model. Methods: Strains of S. pneumoniae with amoxicillin MICs of 1, 2, 4 a
Comparative genomic hybridization (CGH) analysis has shown that chromosome 5q deletions are the most frequent aberration in breast tumors from BRCA1 mutation carriers. To map the location of putative 5q tumor suppressor gene(s), 26 microsatellite markers covering chromosome 5 were used in loss of heterozygosity (LOH) analysis of breast tumors from BRCA1 (n = 42) and BRCA2 mutation carriers (n = 67
Double minutes (dmin)-circular, extra-chromosomal amplifications of specific acentric DNA fragments-are relatively frequent in malignant disorders, particularly in solid tumors. In acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), dmin are observed in similar to 1% of the cases. Most of them consist of an amplified segment from chromosome band 8q24, always including the MYC gene. B
