Cell interdivision periods (IDP) in homogenous cell populations vary stochastically. Another aspect of probabilistic cell behavior is randomness in cell differentiation. These features are suggested to result from competing stochastic events of assembly/disassembly of the transcription pre‐initiation complex (PIC) at gene promoters. The time needed to assemble a proper PIC from different proteins, which must be numerous enough to make their combination gene specific, may be comparable to the IDP. Nascent mRNA visualization at defined genes and inferences from protein level (...) fluctuations in single cells suggest that some genes do operate in this way. The onset of mRNA production by such genes may miss the time windows provided by the cell cycle, resulting in cells differentiating into those in which the respective mRNAs are either present or absent. This creates a way to generate cell phenotype diversity in multicellular organisms. (shrink)

Any more or less serious attempt to deal with even one aspect of the complex and generally still inadequately studied philosophical system of so outstanding a thinker as the famous Russian idealist philosopher Vladimir Sergeevich Solovyov necessarily requires preliminary consideration and evaluation of the philosophic significance of his work as a whole.

The COVID-19 vaccine is one way to prevent the spread of COVID-19. Indonesia has produced Indovac, a COVID-19 vaccine made by Biofarma which has the opportunity to be distributed to countries in the Indo-Pacific Region. This article aims to explain the opportunities and challenges of Indonesia's vaccine diplomacy during the COVID-19 pandemic to the Indo-Pacific region through Biofarma. By using a vaccine diplomacy approach and qualitative methods with System Dynamic analysis, this article concludes that (i) The opportunity for Indonesia's vaccine (...) diplomacy to the Indo-Pacific is 44% and (ii) The simulation results for all parameters have the opportunity to increase Indonesia's progress in the Indo-Pacific except for the parameters of cooperation with special actors vaccine. The challenges for Indonesia's Covid-19 vaccine diplomacy to the Indo-Pacific come from the United States, India, Japan, Australia and Singapore. (shrink)
