FEBS Letters, EarlyView.Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

centrifugeR: Non-trivial balance of centrifuge rotors
, 2022 Centrifuges are indispensable instruments in biology laboratories. For the safe operation of centrifuges, ensuring balance is a must. Loading test tubes in opposite holes and adding dummy tubes are far from the only ways to balance the centrifuge rotors.

Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

About the separation of finely divided particles during centrifugation in liquid media
Вестник КазНУ. Серия математика, механика, информатика, 2018 This work is devoted to the study of centrifugation processes, which are one of the most complex processes of technology. The use of the action of the centrifugal force field for the separation of heterogeneous liquid systems in a rotor system ...

Relativistic centrifugal instability [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2018 Abstract Near the central engine, many astrophysical jets are expected to rotate about their axis. Further out they are expected to go through the processes of reconfinement and recollimation. In both these cases, the flow streams along a concave surface and hence, it is subject to the centrifugal force.

FEBS Letters, EarlyView.The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Open Source Completely 3-D Printable Centrifuge
Instruments, 2019 Centrifuges are commonly required devices in medical diagnostics facilities as well as scientific laboratories. Although there are commercial and open source centrifuges, the costs of the former and the required electricity to operate the latter limit ...
