The human secretory phospholipase A2 group IIA (PLA2-IIA) is a lipolytic enzyme. Its inhibition leads to a decrease in eicosanoids levels and, thereby, to reduced inflammation. Therefore, PLA2-IIA is of high pharmacological interest in treatment of chronic diseases such as asthma and rheumatoid arthritis. Quercetin and naringenin, amongst other flavonoids,(More)
A variety of plant derived substances, so-called phytoestrogens (PEs), although structurally not related to steroids, produce effects similar to the mammalian estradiol. However, little is known so far about the structural requirements which determine PE activities. Taking into consideration that prenylation reactions are relatively common in plant(More)
8-prenylnaringenin (8-PN) and preparations containing 8-prenylnaringenin have been suggested for use in medicinal and cosmetic applications like hormone replacement or bust enhancement. However, the safety of application is still under considerable debate. Recently it has been shown that human liver microsomes are converting 8-prenylnaringenin to 12(More)
We report on the smallest Silicon Photonic modulator and lowest power Complementary Metal-Oxide-Semiconductor Mach-Zehnder Modulator (CMOS MZM) Driver for next generation Coherent Transceivers. Bit-Error-Ratio (BER) characterization of this device demonstrates comparable performance relative to a commercial Lithium Niobate (LN) modulator and capability of(More)
The flavanone naringenin is known to possess only weak estrogenic properties, but some of its derivatives such as 8-prenylnaringenin are potent phytoestrogens. The aim of this study was to further clarify structure-function relationships of flavanones regarding their estrogenic or antiestrogenic properties by characterizing the new chemically synthesized(More)
