Animal experimental studies on partial kidney function after temporary tourniquet ischemia with and without blood substitute therapy

70 rats were subjected to tourniquet ischemia of a hind limb for a period of two and three hours. 12 rats served as controls. After release of the 3 hours tourniquets 20 rats were treated either with Ringer's solution or with hydroxyethyl starch. Kidney function and morphology, systolic blood pressure, hematocrit, serum electrolytes, creatinine and urea were studied as different times of recirculation. 1. Reduction in renal function was only observed after releasing the tourniquets. 2. The extent of reduction in renal function depended on the time of ischemia and time of recirculation. 3 hours of tourniquet with two hours of recirculation led to the largest extent of reduction in renal function and renal parenchymal lesions. 3. If the infusion of HES was applied at the beginning of recirculation, reduction in renal function was prevented, as well as parenchymal lesions. Ringer's infusion, however, did not improve kidney function to a normal range.

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.
