Insect Science, EarlyView.Abstract The sterile insect technique (SIT) is a highly effective biologically‐based method for the suppression of many insect pest populations. SIT efficacy could be improved by methods of male sterilization that avoid the use of irradiation that can result in diminished fitness and mating competitiveness.

Telomeres cluster de novo before the initiation of synapsis: a three-dimensional spatial analysis of telomere positions before and during meiotic prophase. [PDF]
, 1997 We have analyzed the progressive changes in the spatial distribution of telomeres during meiosis using three-dimensional, high resolution fluorescence microscopy.

Neoclassical development of genetic sexing strains for insect pest and disease vector control
Insect Science, EarlyView.The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

Jasmonates enhance plants tolerance grown in Cd‐contaminated environments: A comprehensive overview
Annals of Applied Biology, EarlyView.Jasmonates (JAs) enhance plant tolerance to cadmium (Cd) stress by activating antioxidant defences but may reduce Cd uptake, limiting their effectiveness for phytoremediation. This review compiles studies that evaluated the effects of JA application on plants grown in Cd‐contaminated environments. Abstract Cadmium (Cd) is a toxic heavy metal and one of

Andrology, EarlyView.Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

The use of deidentified organ donor testes for research
Andrology, EarlyView.Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Pharmacogenetics of follicle‐stimulating hormone action in the male
Andrology, EarlyView.Abstract Male factor infertility (MFI) is involved in half of the cases of couple infertility. The follicle‐stimulating hormone (FSH) therapy is considered efficient to improve semen parameters and pregnancy rate in patients with idiopathic MFI, following the lesson learned from hypogonadotropic hypogonadism.
