Mammarenaviruses (genus Mammarenavirus, family Arenaviridae) are rodent-borne zoonotic viruses consisting of 52 viral species, including ten that are pathogenic to humans. Currently, only two endemic mammarenavirus species are known in Europe: the human pathogenic Mammarenavirus choriomeningitidis (LCMV) and the recently discovered hedgehog-origin Mammarenavirus mecsekense (MEMV). In this study, 59 faecal specimens from Northern white-breasted hedgehogs (Erinaceus roumanicus) from different geographic regions in Hungary were investigated for mammarenavirus presence and complete genome characterization using newly designed screening primers by RT-semi-nested PCR and sequencing methods.

Endocrine Division, Department of Medicine, Centre hospitalier de l'Université de Montréal (CHUM), Montreal, Québec, Canada.

Cushing syndrome (CS) is a constellation of signs and symptoms caused by excessive exposure to exogenous or endogenous glucocorticoid hormones. Endogenous CS is caused by increased cortisol production by one or both adrenal glands (adrenal CS) or by elevated adrenocorticotropic hormone (ACTH) secretion from a pituitary tumour (Cushing disease (CD)) or non-pituitary tumour (ectopic ACTH secretion), which stimulates excessive cortisol production. CS is associated with severe multisystem morbidity, including impaired cardiovascular and metabolic function, infections and neuropsychiatric disorders, which notably reduce quality of life.

For individuals at high risk of developing breast cancer, interventions to mitigate this risk include surgical removal of their breasts and ovaries or five years treatment with the anti-estrogen tamoxifen or aromatase inhibitors. We hypothesized that a silicone based anti-estrogen-eluting implant placed within the breast would provide the risk reduction benefit of hormonal therapy, but without the adverse effects that limit compliance. To this end, we demonstrate that when placed adjacent to mammary tissue in the 7,12-dimethylbenz[a]anthracene-induced rat breast cancer model a fulvestrant-eluting implant delays breast cancer with minimal systemic exposure.

Nitrification inhibitors (NIs) are critical to reduce nitrogen (N) leaching losses. However, the efficacy of different NIs can be highly variable across soils and crop types, and a deeper understanding of the mechanistic basis of this efficiency variation, especially in purple soil under vegetable production, is lacking. To enrich this knowledge gap, the impact of different NIs amendment (3,4-dimethylpyrazole phosphate, DMPP; dicyandiamide, DCD; nitrapyrin, NP) on nitrification and the microbial mechanistic basis of controlling nitrate (NO-N) leaching of vegetable purple soil was explored in southwest China.
