Abstract

Among 180 patients with proved adenovirus infection of the eye, 144 infections with adenovirus 8 (Ad 8) were found. 11 or 7 patients were infected with Ad 19 or Ad 4 respectively; further 18 cases were associated with 6 other serotypes. The main symptoms of epidemic keratoconjunctivitis (EKC) (pronounced inflammatory swelling of the plica and caruncula, nummular corneal infiltations) are not confined to Ad 8 infections. For the virological diagnosis, a combination of virus isolation and serology is recommended. Virus isolation is mostly successful from conjunctival swabs obtained during the first week of the disease. For serological investigation, the first blood specimen should be taken as early as possible, the second not earlier than 15 days after onset of disease. The mere application of the group-specific adenovirus complement-fixation is insufficient; it should be supplied by neutralization and hemagglutination-inhibition with Ad 8 (or Ad 19) virus, although these reactions are not invariably type-specific. A swifter diagnosis of the adenovirus infection by immunofluorescence performed in cell cultures inoculated with conjunctival material, 3 or 7 days after inoculation, was often successful; however, this procedure prove...Continue Reading

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.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells.
