Abstract

Reference values for urinary D-glucaric acid and the influence of sex, age and smoking habits were evaluated with a low-pH enzymatic method. D-Glucaric acid measured on spot urine samples from 573 healthy subjects gave mean concentrations (mumol/1) and D-glucaric acid/creatinine ratios (mmol/mol creatinine) of 56.1 (+/- 22.9) and 3.05 (+/- 0.99) for males and 53.3 (+/- 20.9) and 3.35 (+/- 0.95) for females. No difference between morning and evening was observed for urinary D-glucaric acid/1 values, but D-glucaric acid/creatinine was higher in the evening samples for both sexes. There was a negative correlation between D-glucaric acid/1 values and age in males but not in females: the decrease of D-glucaric acid concentration was, however, quantitatively very small. Smoking produced a significant increase in D-glucaric acid concentration and in the D-glucaric acid/creatinine ratio for males and also partially for females.

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.

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.

Social Learning

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

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.
