Phytohormones are substances synthesized by plants which, even in small amounts, have a controlling effect on plant development and differentiation processes, e.g. B. on germination, growth, seed maturity, leaf shedding, flower formation, differentiation and branching. There are many parallels to the effects of hormones in animals, but there are also differences. In contrast to animals, … Read more
Silver nanoparticles (AgNPs) are used very often because they have special antimicrobial and optical properties and have high electrical conductivity. The sonochemical synthesis route using kappa carrageenan is a simple, convenient and environmentally friendly method for the production of silver nanoparticles. The κ-carrageenan serves as a natural, green stabilizer, while high-performance ultrasound acts as an … Read more

The sociology of knowledge carries out a radical sociologization of knowledge: that socialization takes place in the medium of knowledge and that all knowledge is location-bound, authors such as Scheler and Mannheim introduced at the end of the 1920s. Since then, questions about the production of knowledge, the conditions and forms of its reception as … Read more
Die Wirksamkeit der SSRI bei akuten depressiven Episoden ist bereits in vielen kontrollierten klinischen Studien sowie in Metaanalysen nachgewiesen worden. Sie inhibieren die Wiederaufnahme des Neurotransmitters Serotonin (5-Hydroxytryptamin, 5-HT) aus dem synaptischen Spalt in die präsynaptische Nervenzelle; dadurch steigt die 5-HT-Konzentration zwischen den Neuronen, und die serotonerge Signalübertragung im ZNS verbessert sich. Da die pharmakologischen … Read more
