The introduction of distance learning raised questions of self-organization and self-discipline of the student, the desire and ability of the student to independently acquire knowledge, academic integrity of the student. The effectiveness of distance learning depends on the answers to these questions. Therefore, teachers need to analyze the level of self-preparation of each student and, if necessary, motivate them for intensive independent educational work. To obtain objective data on the readiness and attitude of students to distance learning, as well as in order to establish and analyze the advantages and disadvantages of distance learning as students see them, conducted a voluntary anonymous survey using a questionnaire developed by us. The survey was carried out among the students, who studied the discipline “Microbiology, Virology and Immunology” for one semester in the classroom, and the next semester studied remotely using the services of the Microsoft Office 365 platform. Indicators of representativeness of the sample: sample size — 24 respondents, which amounted to 54.5 % of students; the maximum error is 10 % with a probability of 0.90. When analyzing the answers to the questionnaires, we revealed the advantage of positive feedback from students on the introduced distance learning form. Among the positive aspects, students consider remote lecturing and access to lectures read on the MS Teams service of the Microsoft Office 365 platform. Among the disadvantages of distance learning, students especially note the long stay at the monitor and the lack of practical work, especially when studying the discipline “Microbiology, Virology and Immunology”.

Delivering foreign molecules into human cells is a wide and ongoing area of research. Gene therapy, or delivering nucleic acids into cells via nonviral or viral pathways, is an especially promising area for pharmaceutics. All gene therapy methods have their respective advantages and disadvantages, including limited delivery efficiency and low viability. We present an electromechanical method for delivering foreign molecules into human cells. Nanoinjection, or delivering molecules into cells using a solid lance, has proven to be highly efficient while maintaining high viability levels. This paper describes an array of solid silicon microlances that was tested to determine efficiency and viability when nanoinjecting tens of thousands of HeLa cells simultaneously. Propidium iodide (PI), a dye that fluoresces when bound to nucleic acids and does not fluoresce when unbound, was delivered into cells using the lance array. Results show that the lance array delivers PI into up to 78% of a nanoinjected HeLa cell culture, while maintaining 78–91% viability. With these results, we submit the nanoinjection method using a silicon lance array as another promising particle delivery method for mammalian culture cells.

Currently, during the pandemic, the forced transition to distance learning carries a number of problems. These problems affect various aspects of education, including the study of students’ attitudes to distance learning. The purpose of this research is to study the features of the subjective attitude of schoolchildren and students to distance learning. This research involved 140 secondary school students (average age M = 10.7, SD = 7.2 (66.3% men)) and 30 university students (average age M = 22.5, SD = 2.4 (20% men)). The methods used were a questionnaire, Chi-square test and Criterion φ*. Fisher angular transformation. The study showed that schoolchildren do not intend to continue studying in the distance form if they choose, with a generally positive attitude towards distance learning. The self-assessment of motivation to study in a distance format has not changed, both among schoolchildren and students. Students are more likely to have a positive attitude to distance learning than schoolchildren. The variety of choices of advantages and disadvantages of distance learning is greater among students than among schoolchildren. The perspective of this study is thus to study the factors that determine the positive and negative attitudes to distance learning.
