On the 15th of January 2019<\/strong> in Kas\u00e1rne\/Kulturpark, Ko\u0161ice the exhibition called \u201cHuman tear as art\u201d<\/strong> was opened to the public. The aim of the pilot scientific-artistic project is to expound the results of the researchers’ work of the Faculty of Medicine and the Faculty of Science of Pavol Jozef \u0160af\u00e1rik University and the Slovak Academy of Sciences in Ko\u0161ice to the general public by means of images, which refer to an interesting diagnostical potential of the original view of the human tear fluid in case of various illnesses.<\/p>\n

The exhibition consists of 27 images showing interesting structures and patterns, which are displayed patients’ tears and are being presented with the help of an atomic force microscope in nanometers. The organizer of the exhibition is Assoc. prof.\u00a0 Vladim\u00edra Tom\u010dekov\u00e1, PhD. from the Department of Medical and Clinical Biochemistry of the Faculty of Medicine, P. J. \u0160af\u00e1rik University in Ko\u0161ice, who started observing the tear fluid with an atomic force microscope in 2015. Those observations were implemented with the help of Mgr. Vladim\u00edr Komanick\u00fd, PhD. <\/strong>from the Institute of Physics of the Faculty of Science P.J. \u0160af\u00e1rik University, who is also the founder of the nanolaboratory at<\/strong> which these researchers took place.<\/p>\n

People can express different emotions with tears but scientists discovered that tears can reveal the presence of various diseases and considering their structure, every teardrop is unique.<\/p>\n

The pair of researchers during the observation of the microscopic preparations with the naked eye or with using an appropriate software found very interesting structures in the patients\u00b4 tear fluids with various illnesses. The patients were chosen by the Ophthalmologist MUDr. Gabriela Glinsk\u00e1, who was also an external postgraduate student of Asssoc. prof. Tome\u010dkov\u00e1 and was dealing with the topic of her dissertation called \u201cThe diagnostical potential of tears in Ophthalmology. The results of their first experiments engaged the attention of their colleagues from Ko\u0161ice and the team of collaborators has gradually expanded.<\/p>\n

Later RNDr. Oleg Shylenko and his studenst from the Institute of Physics, Faculty of Science P. J. \u0160af\u00e1rik University<\/strong>, Assoc. prof. Nat\u00e1lia Toma\u0161ovi\u010dov\u00e1 and Mgr. Katar\u00edna Zaku\u0165ansk\u00e1 from the Institute of Experimental Physics from the Slovak Academy of Sciences and also other members of the Department of Medical and Clinical Biochemistry from the Faculty of Medicine, P. J. \u0160af\u00e1rik University in Ko\u0161ice started researching the tear fluid.<\/p>\n

The researchers are currently collaborating not only with the Ophthalmologist Gabriela Glinska but also with other doctors from the fields of psychiatry and neurology who provide the tear fluid samples of patients. The samples are taken with a help of a glass micro-capillaries or Sugi sponges, but most often with a help of an irrigation method using physiological solution, which enables taking the highest content of tear fluids.<\/p>\n

The researchers are observing patterns of tear fluids from various members of the project with the help of various microscopical methods \u2013 fluorescent spectrophotometry, atomic force microscope, infrared spectrophotometry, gel zymography and circular dichroism. They focused their observations on the tears of ill patients in which were formed different prints by the means of dendrites: shapes of hearts, branchlet, feather and grain blades which do not occur in tear fluids of healthy people.<\/p>\n

According to the organizer of the exhibition, Assoc. Prof. Tome\u010dkov\u00e1, the researchers were surprised by the aesthetical and original potential of the tear fluid images, which contributed to the printing of these captured structures in higher resolutions. This is how the idea of the exhibition of scientific images with the name \u201cHuman tear as art\u201d was born, which helped to bring the gained knowledge into sight to the general public and to connect art with science to one unit.<\/p>\n

After the exhibition the images will be hanged in the nanolaboratory of the Faculty of Science, P.J. \u0160af\u00e1rik University, where the measures were originally taken.<\/strong><\/p>\n
