Tamm-Horsfall glycoprotein preparations were obtained from calf urine by 1.0 M NaCl precipitation followed by 4 M urea/Sepharose 4B chromatography. By using 0.1% sodium dodecyl sulfate polyacrylamide gel electrophoresis a molecular weight of 86 500 +/- 4500 (n = 12) was calculated for the glycoprotein. Amino acid and carbohydrate analyses were performed, the carbohydrate composition being (in residues per 100 amino acid residues in the glycoprotein): fucose, 0.90; galactose, 4.82; mannose, 4.63;N-acetylglucosamine, 7.36; N-acetylgalactosamine, 1.38; sialic acid, 2.93. Under conditions of mild acid hydrolysis (0.05 M H2SO4, 80 degrees C, 1 h) the calf Tamm-Horsfall glycoprotein preparations were degraded partially into two lower molecular weight fragments (approximate Mr 66 000 and 51 000), as shown by polyacrylamide gel electrophoresis, both fragments being periodic acid-Schiff reagent positive.

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.

Systemic Juvenile Idiopathic Arthritis

Systemic juvenile idiopathic arthritis is a rare rheumatic disease that affects children. Symptoms include joint pain, but also fevers and skin rashes. Here is the latest on this disease.

Chromatin Regulation and Circadian Clocks

The circadian clock plays an important role in regulating transcriptional dynamics through changes in chromatin folding and remodelling. Discover the latest research on Chromatin Regulation and Circadian Clocks here.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain.
