Sexually Dimorphic Neurosteroid Synthesis Regulates Neuronal Activity in the Murine Brain.
Philipp Wartenberg, Imre Farkas, Veronika Csillag, William H Colledge, Erik Hrabovszky, Ulrich Boehm
Oct 13, 2021
Sex steroid hormones act on hypothalamic kisspeptin neurons to regulate reproductive neural circuits in the brain. Kisspeptin neurons start to express estrogen receptors in utero, suggesting steroid hormone action on these cells...
Female sexual behavior in mice is controlled by kisspeptin neurons.

Sexual behavior is essential for the survival of many species. In female rodents, mate preference and copulatory behavior depend on pheromones and are synchronized with ovulation to ensure reproductive success. The neural...
Photoinactivation of Eight Health-Relevant Bacterial Species
It is presently unknown to what extent the endogenous direct, endogenous indirect, and exogenous indirect mechanisms contribute to bacterial photoinactivation in natural surface waters. In this study, we investigated the...

A Cyan Fluorescent Reporter Expressed from the Chloroplast Genome of Marchantia polymorpha.
Recently, the liverwort Marchantia polymorpha has received increasing attention as a basal plant model for multicellular studies. Its ease of handling, well-characterized plastome and proven protocols for biolistic plastid...
Highly reactive bis-cyclooctyne-modified diarylethene for SPAAC-mediated cross-linking.
Alexander V Strizhak, Krishna Sharma, Oleg Babii, Sergii Afonin, Anne S Ulrich, Igor V Komarov, David R Spring
Dec 04, 2018
Photoisomerizable diarylethenes equipped with triple bonds are promising building blocks for constructing bistable photocontrollable systems. Here we report on the design, synthesis and application of a cross-linking reagent...
