Abstract

Increased intracranial pressure due to brain oedema was produced in albino rabbits by combining a cryogenic lesion in the left hemisphere with the intraperitoneal administration of 6-aminonicotinamide (cytotoxic agent). The most effective reduction in ICP (74%) was achieved when furosemide and mannitol were used in combination. When either mannitol or furosemide was employed alone, the average ICP reduction was approximately 53%. Peak ICP reduction occurred at 45 minutes with furosemide, 30 minutes with mannitol and furosemide combined, and at 60 minutes with a combination of mannitol and acetazolamide. Also studied simultaneously in these animals were investigated elastance (Em), brain water content, hemispheric water volume content, electrolytes, EEG, and gross pathology. Following therapy there was a statistically significance reduction of water content in the left hemisphere (cryogenic lesion) by all therapeutic modalities except with furosemide alone. In the right hemisphere the water content was reduced by furosemide and the furosemide-mannitol combination but not by the association of mannitol with acetazolamide. A significant decrease of brain sodium was noted only for the combination of mannitol and furosemide. This st...Continue Reading

COVID-19

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.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Lipidomics & Rhinovirus Infection

Lipidomics can be used to examine the lipid species involved with pathogenic conditions, such as viral associated inflammation. Discovered the latest research on Lipidomics & Rhinovirus Infection.

Glut1 Deficiency

Glut1 deficiency, an autosomal dominant, genetic metabolic disorder associated with a deficiency of GLUT1, the protein that transports glucose across the blood brain barrier, is characterized by mental and motor developmental delays and infantile seizures. Follow the latest research on Glut1 deficiency with this feed.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

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.
