Novel resin tissue array system reduces sample preparation time, labour and reagent costs in bone tissue histology.

Resin histology plays an essential role in the analysis of hard tissues, such as bone and teeth, as well as in the context of metallic implant analysis. However, the techniques of resin embedding, followed by ground sectioning, are very costly due to significantly increased reagent cost and labour time when compared to the conventional paraffin histology approach. In the present study, a novel resin array system was developed to increase the affordability of a project analysing rat femur tissues containing metallic or polymeric implants.

Ureaplasma parvum and Ureaplasma urealyticum are detected in semen after washing before assisted reproductive technology procedures.

Objective: To investigate the prevalence of ureaplasmas in semen and washed semen and to explore their effect on semen andrology variables.

Design: Prospective study.

Setting: In vitro fertilization (IVF) unit of a private hospital.
