Having studied anaesthetic drug interactions in rats, we report the effects of halogenated anaesthetics on the liver glutathione levels and histology, as well as the results of the enhancement of these effects by microsomal enzyme induction. The anaesthetic agents studied included methoxyflurane, halothane, ethrane, chloroform and fluroxene. While exposure of rats to methoxyflurane, helothane and ethrane produced no significant changes in hepatic glutathione levels, or in liver histology, exposure to chloroform and fluroxene produced marked depression of liver glutathione, especially after microsomal enzyme induction. Furthermore, rats exposed to thses agents after enzyme induction developed gross centrilobular necrosis and died. It is suggested that the study of the effects of any new anaesthetic agent on liver glutathione levels could be a valuable screening test of its hepatotoxic potential, before its clinical trial.

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.
