Immunodiffusion studies of various structural preparations from mycobacterial cells

Various structures and other preparations from mycobacterial cells were analyzed by immunodiffusion. The preparations were obtained from four strains referred to the species Mycobacterium bovis (BCG), Mycobacterium fortuitum, Mycobacterium phlei and Mycobacterium smegmatis. They represented cell walls (CW), culture filtrates (CF), artificially disintegrated cell material (XP), protoplasms (PP), crude ribosomes (CR), ribosomal 50S subunits (50S), ribosomal 30S subunits (30S), ribosomal 16S core particles (16S) and ribosomal-free fractions (UCS). The preparations were analyzed by reference precipitation systems based on CF, CR and 30S preparations. Serological comparisons were made with material from the same species and cross-testing between material from different species was not performed. It was shown that from the precipitinogenic point of view the CF and XP materials were very similar and that they both contained protoplasmic material to a large extent. Furthermore, it was found that ribosomal precipitinogens constitute an important part of the precipitinogens in PP as well as in the CF and the XP preparations. The ribosomal precipitinogens were found to represent the two subunits as well as the 16S core particle. One ribos...Continue Reading

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.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.

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.

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.


Incretins are metabolic hormones that stimulate a decrease in glucose levels in the blood and they have been implicated in glycemic regulation in the remission phase of type 1 diabetes. Here is the latest research.

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.

Long COVID-19

“Long Covid-19” describes illness in patients who are reporting long-lasting effects of the SARS-CoV-19 infection, often long after they have recovered from acute Covid-19. Ongoing health issues often reported include low exercise tolerance and breathing difficulties, chronic tiredness, and mental health problems such as post-traumatic stress disorder and depression. This feed follows the latest research into Long Covid.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.
