2. Exploring evolutionary and chemical space using chemoinformatic tools and traditional methods in pharmacognosy
Sammanfattning : The number of new drugs coming to the market is declining while interest in lead discovery from natural resources is seeing a revival. Although methods for isolation and identification of natural products have advanced tremendously, methods for selection of potential leads have fallen behind. LÄS MER
3. Polyporoid fungi of Tanzania : Taxonomy, transcriptomics and biochemical analyses of Kusaghiporia usambarensis and Piptoporellus baudonii
Sammanfattning : Polyporoid fungi refers to basidiomycetes with fruiting bodies with the hymenium located to the inner surfaces of pores or narrow tubes. The majority of polyporoids belongs to Polyporales. Most Polyporales are saprobes, but some are plant pathogens. LÄS MER
Sammanfattning : Vasodilator responses to endothelium-derived hyperpolarizing factor (EDHF) and anandamide in isolated arteries were investigated. A combination of the potassium channel blockers charybdotoxin and apamin inhibits EDHF-mediated relaxations. LÄS MER
Sammanfattning : In the oxyntic mucosa of the mammalian stomach, histamine is stored in enterochromaffin-like (ECL) cells and in mucosal mast cells. The activity of the histamine-forming enzyme, histidine decarboxylase (HDC), is high in ECL cells but lower in the mucosal mast cells. LÄS MER
