Cerebral Function Monitor (CFM) and electroencephalography (EEG). Experimental study

This work is an attempt to connect the electro-encephalogram (EEG) and monitor of cerebral function (MCF) recordings during the experimental stimulation of the rabbit brain whether this is in the from of direct central stimulation, by stereotaxic location, or in the form of indirect stimulation via a peripheral nerve. These stimulations, performed under alfadione anaesthesia or under the neuroleptanalgesic sedative effect of chlorprothixine, are compared for every animal with the results of the control stimulations. The cardiovascular responses are recorded simultaneously. It has been found that, in simple narcosis induced by alfadione, there is much variation in the EEG recording and even more so in the MCF recording according to the quantity used and the block of responses to stimuli does not appear until there is deep anaesthesia. However, when chlorprothixine is used, the MCF trace is found to be very closely related to the trace of mild anaesthesia with accompanying block to all of the nociceptive stimulations. It would seem, therefore, if we accept the concept of levels of cerebral activity, that the use of the MCF could well open the way to a better understanding of the pure narcotic phenomena and of the neurovegetative ...Continue Reading

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

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.

Femoral Neoplasms are bone tumors that arise in the femur. Discover the latest research on femoral neoplasms here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
