Flowers sensu lato are short, specialized axes bearing closely aggregated sporophylls. They are typical for seed plants (spermatophytes) and are prominent in flowering plants sensu stricto (angiosperms), where they often comprise an attractive perianth. There is evidence that spermatophytes evolved from gymnosperm-like plants with a fern-like mode of(More)
Floral organ identity is largely controlled by the spatially restricted expression of several MADS-box genes. In Antirrhinum majus these organ identity genes include DEF, GLO and PLE. Single and double mutant analyses indicated that the type of organ found in a particular whorl is dependent on which combination of these genes is expressed there. This paper(More)
The aetiology of severe asthenozoospermia in men with spinal cord injury includes an adverse impact of seminal plasma (SP) on sperm motility. In this study we investigated the effect exerted by SP from men with SCI on donor sperm mitochondrial activity and its reflection on motility. Donor spermatozoa were exposed (1 h) to SP from 22 ejaculates of men with(More)
Oxidative stress (OS) plays an essential role in male infertility aetiology by affecting sperm quality, function, and also the integrity of sperm DNA. The assessment of oxidative stress in semen may be an important tool to improve the evaluation of sperm reproductive capacity. The purpose of this study was the evaluation of any possible relation between the(More)
The role of oxidative stress (OS) in female reproduction is an understudied area for investigation. The aim of the study was to assess reactive oxygen species (ROS) levels both in follicular fluid (FF) and in serum samples of women undergoing IVF and to relate them to clinical outcomes. A total of 56 women were enrolled. From each patient a sample of serum(More)
