Crimean-Congo haemorrhagic fever (CCHF) is a viral zoonotic disease endemic to regions of Africa, the Balkans, the Middle East, and Asia, with increasing reports of cases in southern Europe. Human transmission occurs primarily through the bite of infected ticks and by body fluids from infected human. Crimean-Congo haemorrhagic fever virus (CCHFV) affects a broad host range, including both domestic and wild vertebrates.

Hookworm infection represents a major global disease burden, in terms of both morbidity and economic impact, and there has been a resurgence of hookworms in developed nations where these parasites were once thought to be eradicated. Hookworms can infest humans or other mammals as their primary hosts depending on the species. The 2 most common species that seek human hosts-Necator americanus and Ancylostoma duodenale-enter the body through the epidermis, and hookworm infection may manifest as a pruritic and papular inflammatory reaction know as ground itch.

Despite the wide use of zebra finches as an animal model to study vocal learning and production, little is known about impacts on their welfare caused by routine experimental manipulations such as changing their social context. Here we conduct a post-hoc analysis of singing rate, an indicator of positive welfare, to gain insights into stress caused by social isolation, a common experimental manipulation. We find that isolation in an unfamiliar environment reduces singing rate for several days, indicating the presence of an acute stressor.

Background: Alzheimer's disease (AD) blood biomarkers alone can detect amyloid-β (Aβ) pathology in cognitively unimpaired (CU) individuals. We assessed whether combining different plasma biomarkers improves the detection of Aβ-positivity and identifies rapid amyloid deposition in CU individuals.
Method: CU participants from the ALFA+ cohort were included.

Background: To date, limited data exist concerning the utility of FDG-PET in detecting Alzheimer's Disease (AD) in Down Syndrome (DS). Yet, sensitive biomarkers for neurodegeneration are essential in this population genetically predisposed for AD. Therefore, we aimed at characterizing the effect of age, disease stage and AD pathology on brain metabolism in a large cohort of adults with DS.
