The emergence of COVID-19 (SARS-CoV-2) has presented public health professionals with new challenges in the diagnosis of the disease and treatment of patients. Nowadays, the epidemiology, clinical features, prevention and treatment of the disease are studied poorly due to continuous mutation of the pathogen. One of the consequences of the new coronavirus infection could be changes in the immune system of the human population.

The objectives of this study were as follows: (i) to describe and evaluate the frequencies of different morphologies of llama sperm nuclei, (ii) to determine morphometric values of nuclear parameters, (iii) to describe and estimate the frequencies of different classes of chromatin distribution and (iv) to measure haploid DNA content and analyse its nuclear distribution. The study was performed using ejaculates collected from seven males, and sperm nuclei were stained with the Feulgen reaction. Normal morphology ranged from 78.

Background & Aims: Hepatocytes differ from one another by the degree of the ploidy, size, position in the liver lobule, and level of the DNA-synthetic processes. It is believed, that the cell size exerts substantial influence on the metabolism of the hepatocytes and the glycogen content in them. The aim of the present study was to test this hypothesis.

Background: For CSF analysis, exact knowledge of the type and amount of cells is essential, especially for detection of infection or bleeding. The chamber count has been the current reference method to date, yet it is problematic due to its subjectivity depending on the examiner's skill and experience. Therefore, as a reference method, we used an impulse cytophotometric measurement with Epics XL owing to its improved objectify ability and compared this method to the measurement of CSF samples performed with the ADVIA 2120 and XE-5000.

The paper compares and contrasts the results of measuring the hepatocyte cytoplasm area and RNA content in 35 gerbils in three series of experiments, i.e. the vivarium control, modeled space flight (synchronous control) and exposure to the factors of 12-d Foton-M3 orbital flight.
