The Covid-19 pandemic has been the highest disruptive event in the world recent history. Worldwide academic research on this topic has led to an explosion of scientific literature, never seen before. Bibliometrics provide methods to illustrate this exceptional phenomenon in academic publications. The objective of this paper is to analyze the Covid-19 research from a bibliometric perspective and to study the impact of the publication explosion on bibliometric indicators. The present study shows how an exceptional phenomenon has a disruptive impact on bibliometric indicators, such as the h-index and the Journal Impact Factor. The higher the specialization, the higher the possible impact of a disruptive phenomenon. In applied sciences, more important than the research or the discipline, the specific theme of the research is crucial for citations of articles and for their impact. The salience of the topic, the magnitude of the problem at study and the urgency to find solutions are drivers for citations. The study of the Covid-19 research illustrates the relativity of indicators and the need for context. The present study also confirms the plead for responsible metrics of the San Francisco Declaration on Research Assessment (DORA).

Coronaviruses are characterized by their progeny assembly and budding in the endoplasmic reticulum-Golgi intermediate compartment (ERGIC). Our previous studies demonstrated that truncation of 9 amino acids in the cytoplasmic tail (CT) of the infectious bronchitis virus (IBV) spike (S) protein impairs its localization to the ERGIC, resulting in increased expression at the plasma membrane. However, the precise mechanism underlying this phenomenon remained elusive.

Melatonin is a multifunctional biomolecule with demonstrated stimulatory, inhibitory, and antioxidant effects, including both receptor-mediated and receptor-independent mechanisms of action. One of its more perplexing effects is the disruption of regeneration in planaria. Head regeneration in planaria is a remarkable phenomenon in which stem cells (neoblasts) migrate to the wound site, proliferate, then differentiate into all functional tissue types within days of injury.

Crohn's disease (CD) is a chronic inflammatory autoimmune disease of unknown etiology. To identify new targets related to the initiation of CD, we screened a pair of twins with CD, which is a rare phenomenon in the Chinese population, for genetic susceptibility factors. Whole-exome sequencing (WES) of these patients revealed a mutation in their SERPINB4 gene.

The National Aeronautics and Space Administration (NASA) in the United States has been studying a fascinating and unique constellation of neuro-ophthalmic findings collectively known as Spaceflight Associated Neuro-Ocular Syndrome (SANS). SANS is unique to the space environment of microgravity and produces novel physiological and pathological findings that have no direct terrestrial equivalent. The neuro-ophthalmic phenomenon is a major physiologic barrier to future planetary spaceflight.

The extracellular matrix (ECM) and its primary chemical components, including collagen, play a pivotal role in carcinogenesis and tumor progression. The ECM actively regulates cell proliferation, migration, and, importantly, resistance to various adverse factors. It is widely recognized as a key factor in modifying the resistance of tumor cells to various treatment modalities and cytotoxic compounds.
