Diabetes-induced alterations of autonomic nerve function in the cat

The susceptibility to competitive ganglionic blocking agents such as hexamethonium (C6), tetraethylammonium bromide (TEAB), mecamylamine and d-tubocurarine (d-TC), of the superior cervical ganglion in cats with pancreatectomy and spontaneous diabetes or in animals treated with contrainsular drugs such as cortisone or dihydrochlorothiazide, was found to be decreased as compared to the reactivity of normal controls. The increased tolerance to ganglioplegics was not correlated with the elevation of the blood sugar level, and proved to be resistant to an acute administration of insulin. The results could not be explained by a decrease in the specific cholinesterase activity of the ganglionic tissue due to diabetes. Alteration of the peripheral autonomic synaptic transmission may be an early sign of diabetic neuropathy.

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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
