Abstract

Antigens of zona pellucida (ZP) of different mammalian species, including the man, were studied by means of various immunochemical methods. The analysis was carried out using rabbit antisera to the pig, mouse, guenon and Java macaque eggs. After immunoadsorption (by blood serum and tissue extracts) these anti-ZP-sera reacted with water-insoluble ZP components only (in immunofluorescence). The adsorbed anti-ZP-sera were specific not only to homologous ZP, but also to ZP of other mammalian species. The spectrum of antigens of the ape ZP was most closely related to that of human ZP. The pig eggs contained antigens common with the human ZP as well. The antiserum to the mouse ZP did not react with ZP of man, ape, pig, cow, rabbit and other species under study. The blood of sterile women contained the antibodies reacting (in immunofluorescence) with ZP of mouse, pig, guinea pig, sheep and man (very weakly). The data obtained suggest the complexity of antigenic mosaic of the mammalian ZP including both "cross-reacting" (common) antigens and species specific ones.

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.

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

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.

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.
