Acute promyelocytic leukaemia with PML-RARA fusion is usually associated with the t(15;17)(q24.1;q21.1) translocation but may also arise from complex or cryptic rearrangements. The fusion usually resides on chromosome 15 but occasionally on others. We describe a cryptic PML-RARA fusion within a novel chromosome 17 rearrangement. We performed interp...

Motility characteristics (assessed subjectively and with computer‐assisted semen analysis) and membrane status (after staining with chlortetracycline) of washed and non‐washed frozen–thawed ram spermatozoa were evaluated after incubation in buffer and buffer containing autologous whole seminal plasma or one of its two fractions: the pellet...
The components of ruminant seminal plasma and their influence on the fertility of spermatozoa are reviewed. Seminal plasma can both inhibit and stimulate sperm function and fertility through the multifunctional actions of organic and inorganic components. These effects are now better understood because the composition of the seminal plasma, includi...
Whole seminal plasma from ram semen collected before and after vasectomy was separated into 2 fractions, supernatant and pellet of vesicles, and their protein profiles characterized by one-dimensional (1D) gel electrophoresis. The effects of autologous whole seminal plasma and these fractions on motility characteristics (assessed subjectively and b...

The hypothesis tested in this study was that the membrane vesicles present in ram seminal plasma are of testicular origin, rather than being secreted by the accessory sex glands as has been previously reported for a number of species. Membrane vesicles were present in cellular extracts from reproductive organs and accessory sex glands of s...

Membrane vesicles, separated by differential centrifugation from the seminal plasma, were detected in the sperm‐rich ejaculate fractions of four boars and three stallions, and in the whole ejaculates of seven rams. The volume and percentage of vesicles, determined by a stereological technique, were higher in the sperm‐rich than in the post...
