The cell cycle covers cell proliferation and growth and is strictly regulated by cyclin-dependent kinase, cyclins and their inhibitors. Cyclin-dependent kinases are serine/threonine kinases that are activated in certain phases of the cell cycle by regulatory subunits, cyclins, with which they form functional heterodimeric complexes. Under physiological conditions, the activation of cyclin-dependent kinases and cyclins is strictly controlled. ⋯ Each cell cycle consists of two phases, interphase and mitotic phase. Their dysregulation leads to disruption of cell cycle coordination and uncontrollable cell proliferation, which is the main feature of tumorigenesis (Fig. 1, Ref. 69). Keywords: cell cycle, regulation, cyclin‑dependent kinases, cyclins, inhibitors.

This study aimed to analyze the global profile of the literature in non-alcoholic fatty liver disease (NAFLD) research. ⋯ This study provides a unique composite picture of NAFLD research worldwide and evaluates research productivity from 1973 to 2022. This finding suggests that the prospects for interventions in NAFLD remain promising (Tab. 5, Fig. 4, Ref. 57). Text in PDF www.elis.sk Keywords: bibliometric analysis, NAFLD, Scopus.

The coronavirus disease 2019 (COVID-19) causes acute respiratory illness and multi-organ failure. The critical roles of magnesium in human health suggest that it could have an active role in the prevention and treatment of COVID-19. We measured magnesium levels in hospitalized COVID-19 patients concerning disease progression and mortality. ⋯ We found no relation between hypomagnesaemia on COVID-19 progression, although hypermagnesaemia could affect COVID-19 mortality (Tab. 4, Ref. 34).

The indication for primary surgical resection or neoadjuvant therapy in lower and middle rectal cancers is often disputable. The aim of the study was to evaluate the occurrence of local recurrence of rectal cancer as for a period of at least 4 years after radical resection. The second aim was to evaluate and compare the results of preoperative magnetic resonance (MR) staging with definitive histology. ⋯ Study also shows that the indication for preoperative radiotherapy for lower and middle rectal cancers based on N status is inaccurate and leads to unnecessary indications for preoperative radiotherapy which may decrease the patients´ quality of life and increase the post‑operative complications. We have also shown that leaving out the N-based radiotherapy from indications does not lead to an increase in the number of local recurrences in lower and middle rectal cancers (Tab. 1, Fig. 5, Ref. 22). Text in PDF www.elis.sk Keywords: rectal cancer, neoadjuvant therapy, local recurrence.

The aim of this study was to investigate bleeding risk in patients treated with VKAs after ground-level falls, considering the type and severity of bleeding. ⋯ Our results show that occurrence of falls in AF patients treated with VKAs have no significant impact on the incidence of severe bleeding and 5-year mortality and that spontaneous bleeding was associated with a significantly higher risk of severe bleeding compared to bleeding after falling (Tab. 4, Ref. 30).
