Current Understanding of Central Nervous System Drainage Systems: Implications in the Context of Neurodegenerative Diseases. Curr Neuropharmacol. 2019 Nov 12;: Authors: Nikolenko VN, Oganesyan MV, Vovkogon AD, Nikitina AT, Sozonova EA, Kudryashova VA, Rizaeva NA, Cabezas R, Avila-Rodriguez M, Neganova ME, Mikhaleva LM, Bachurin SO, Somasundaram SG, Kirkland CE, Tarasov VV, Aliev G Abstract Until recently, it was thought that there were no lymphatic vessels in the central nervous system (CNS). Therefore, all metabolic processes were assumed to take place only in the circulation of the cerebrospinal fluid (CSF) and through the blood-brain barrier's (BBB), which regulate ion transport and ensure the functioning of the CNS. However, recent findings yield a new perspective: There is an exchange of CSF with interstitial fluid (ISF), which is drained to the paravenous space and reaches lymphatic nodes at the end. This circulation is known as the glymphatic system. The glymphatic system is an extensive network of meningeal lymphatic vessels (MLV) in the basal area of the skull that provides another path for waste products from CNS to reach the bloodstream. MLV develop postnatally, initially appearing around the foramina in the basal part of the skull and the spinal cord, thereafter sprouting along the skull's blood vessels and spinal nerves in various areas of the meninges. VEGF-C protein (vascular endothelial growth factor), expressed mainly by vascular smooth ...
Neurologic disease in horses can be particularly challenging to diagnose and treat. These diseases can result in economic losses, emotional distress to owners, and injury to the horse or handlers. To date, there are 5 neurologic diseases caused by known genetic mutations and several more are suspected to be heritable: lethal white foal syndrome, lavender foal syndrome, cerebellar abiotrophy, occipitoatlantoaxial malformation, and Friesian hydrocephalus. Genetic testing allows owners, breeders, and veterinarians to make informed decisions when selecting dams and sires for breeding or deciding the treatment or prognosis of a neurologic animal.
CONCLUSIONS: The GXT provided only a peak VO2 but not the VO2max. Consequently, the real VO2max and PPO could be provided by only VP administrations. This is likely to result from the lower Qc and SV responses observed from a prolonged incremental test protocol when compared to short bouts of constant work rate trials.

Cytokine storm is an acute hyperinflammatory response that may be responsible for critical illness in many conditions including viral infections, cancer, sepsis, and multi-organ failure. The phenomenon has been implicated in critically ill patients infected with SARS-CoV-2, the novel coronavirus implicated in COVID-19. Critically ill COVID-19 patients experiencing cytokine storm are believed to have a worse prognosis and increased fatality rate. In SARS-CoV-2 infected patients, cytokine storm appears important to the pathogenesis of several severe manifestations of COVID-19: acute respiratory distress syndrome, thromboembo...

CONCLUSIONS: This study addresses a gap in current research and holds important implications for enhancing care planning participation by residents with severe dementia. CLINICAL IMPLICATIONS: Residents with severe dementia can successfully participate in activity preference discussions without proxy participation. Residents may comprehend interview questions better when provided in a supported format. PMID: 32633699 [PubMed - as supplied by publisher]
