Sex Preselection: an aid to couples or a threat to humanity? [PDF]

open access: yesHuman Reproduction, 1999
On September 10 1998 the Italian press reported the discovery of a new method to predetermine the sex of a new baby with 90% accuracy. The method is beneficial in many ways and no ethical impediments to the technology have been noted from the point of view of the fetus or of the couple requesting the preselection for strictly medical reasons. However

Whole‐slide analysis of mitotic activity in melanoma reveals higher‐proliferation hotspots and distinct spatial patterns

open access: yesHistopathology, EarlyView.
Whole‐slide analysis of melanoma identified higher‐proliferation mitotic hotspots than routine pathology assessment and revealed distinct spatial patterns of mitotic organization, highlighting the potential of computational mitosis mapping to provide insights beyond conventional mitotic counting.

A double‐blind randomized controlled trial of personalized upper‐alpha neurofeedback in children with ADHD

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Neurofeedback (NF) is a nonpharmacological approach for ADHD, but standard protocols often overlook individual EEG variability, potentially limiting efficacy. We report the first double‐blind randomized controlled trial of a session‐adaptive individualized upper‐alpha NF protocol in children with ADHD, based on individualized 1/f + alpha ...

Healthy Aging Men Do Not Suffer From Relevant Limitations of Their Reproductive Functions

open access: yesAndrology, Volume 14, Issue 6, Page 1504-1514, September 2026.
ABSTRACT Background While metabolic disorders are well‐established contributors to testosterone decline and erectile dysfunction (ED), little is known about the natural progression of reproductive parameters in healthy aging men. Objectives This study aimed to evaluate longitudinal changes in reproductive parameters and sought to determine the ...

Relative effectiveness in genetic gain from genomic selection of candidate dams versus genomic selection of their progeny

open access: yesJDS Communications
The ability to genomically predict the genetic merit of individuals coupled with the widespread availability of sex-sorted semen is causing a paradigm shift in global animal breeding. Many dairy producers wish to minimize the number of surplus dairy-bred
