Delimitation of the time of death by immunohistochemical detection of insulin in pancreatic beta-cells

To improve the possibilities to delimitate the time of death after longer laytime, it was examined if this is possible by immunohistochemical insulin detection. The results show that in our examination material, the pancreatic beta-cells of up to 12-day-old corpses produce a positive immunoreaction towards insulin in all cases, whereas none of the corpses older than 30 days show such a reaction. This means that in case of a negative immunoreaction, the time of death can be assumed to lie more than 12 days before the autopsy. The fact that a negative immunoreaction occurs consistently after 30 days leads to the conclusion that when insulin has been stained in a specimen, the death of the respective person must lie a maximum of 29 days earlier, whereby these time-limits may change in considerably different surrounding conditions.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.

Long COVID-19

“Long Covid-19” describes illness in patients who are reporting long-lasting effects of the SARS-CoV-19 infection, often long after they have recovered from acute Covid-19. Ongoing health issues often reported include low exercise tolerance and breathing difficulties, chronic tiredness, and mental health problems such as post-traumatic stress disorder and depression. This feed follows the latest research into Long Covid.
