Sonographic appearance of angiomyofibroblastoma-like tumor of the scrotum

open access: yesJournal of Ultrasonography, 2019
A variety of extratesticular tumors and tumor-like conditions can occur in the scrotum. Angiomyofibroblastoma is a rare, slow-growing, well-circumscribed mesenchymal tumor, found predominantly in women, and is even a more unusual occurrence in the male ...

Kooperative Redox‐Katalyse der N2O‐Zersetzung mittels auf Co3O4 geträgerten RhOx‐ und CeOx‐Spezies mit kurzreichweitiger Wechselwirkung

open access: yesAngewandte Chemie, EarlyView.
A short‐range Rh‐O‐Co‐O‐Ce interfacial moiety drives low‐temperature N2O decomposition via a cooperative redox cycle. Operando modulated‐excitation XAS with phase‐sensitive detection (ME‐XAS+PSD) tracks rapid, reversible Rh oxidation coupled to Co reduction. Combined kinetics and DFT rationalize the activity trends and identify the Rh‐O‐Co interface as

Hydrogen sulfide and its potential as a possible therapeutic agent in male reproduction

open access: yesFrontiers in Endocrinology
Hydrogen sulfide (H2S) is an endogenously produced signaling molecule that belongs to the group of gasotransmitters along with nitric oxide (NO) and carbon monoxide (CO). H2S plays a pivotal role in male reproductive processes.

Evolutionary Dynamics of Male Reproductive Genes in the Drosophila virilis Subgroup

open access: yesG3: Genes, Genomes, Genetics, 2017
Postcopulatory sexual selection (PCSS) is a potent evolutionary force that can drive rapid changes of reproductive genes within species, and thus has the potential to generate reproductive incompatibilities between species.

Interdigitale Aptamer‐Sensoren mit komplementären Messkanälen zur schnellen Detektion kleiner Moleküle in Biofluiden

open access: yesAngewandte Chemie, EarlyView.
Ein elektrochemischer Aptamer‐Sensorchip nutzt Interdigitalelektroden mit selektiver Monoschicht‐Funktionalisierung, um Dopamin und Cortisol mittels robuster komplementärer „Signal‐Off/On“‐Antworten zu detektieren. Diese Dual‐Channel‐Signalumwandlung ermöglicht eine schnelle Detektion innerhalb von 5–30 min bei geringen Probenvolumina in künstlicher ...
