Long-term results of a modified Spitzy shelf operation for hip dysplasia: 79 adults with a mean follow-up of 33 years.

Background: There is no consensus regarding the treatment of symptomatic hip dysplasia in adolescents and adults. Most previous studies have insufficient follow-up time.

Aim: The aim of this study was to assess the long-term outcome of a modified Spitzy shelf procedure.

Relationship between sperm motility characteristics and ATP concentrations, and association with fertility in two different pig breeds.

Boar fertility has a major impact on overall pig reproductive efficiency. Using accurate and objective in vitro sperm variables for predicting in vivo fertility from a single ejaculate, however, is challenging. Motility is the most widely used indicator of sperm quality, and a computer assisted sperm analysis (CASA) system is now available for objective assessment of sperm motility characteristics.

Development of a gene transfer system for curing of plasmids in the marine fish pathogen Vibrio salmonicida.

All reported natural isolates of the marine fish pathogen Vibrio salmonicida contain plasmids, and in another marine fish pathogen, Vibrio anguillarum, it has been shown that a plasmid is important for expression of virulence by the organism. To study the function of the plasmids in V. salmonicida, we developed a gene transfer system based on the plasmid RSF1010 replicon.
