Endoparasitoids possess a whole set of virulence factors to counter the immune response of their host, among which can be found venom, endosymbiotic viruses and ovarian proteins. Depending on the species, some factors are expected to be less necessary than others. Notably, venom is reported as inessential in some parasitoids bearing viruses.

Warm-activated POA neurons suppress energy expenditure via brown adipose tissue (BAT) projecting neurons in the dorsomedial hypothalamus/dorsal hypothalamic area (dDMH/DHA). Our earlier work identified leptin receptor (Lepr)-expressing, BAT-projecting dDMH/DHA neurons that mediate metabolic leptin effects.

Utilizing a multimodality approach enhances the characterization of the mass for optimal diagnostic outcomes. The recommended primary treatment involves complete surgical resection coupled with adjuvant radiochemotherapy.

Accompanied by similar compounds like halogenated natural products (HNPs), their regular monitoring in fish and their predators is an important task. While different procedures have been developed, the removal of the lipid matrix, mainly carried out by treatment with sulfuric acid or by gel permeation chromatography (GPC), is an indispensable step during sample preparation.
