Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Vertical Turbine Pump Reliability Improvement [PDF]
, 2018 Case StudyThe subject pump was designed and installed when pipeline pressure was estimated high based on a higher production volume. The selected multistage vertical turbine-pumps are generically prone to vibration issues due to its flexible shaft design.

FEBS Letters, EarlyView.Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Journal of Indira Gandhi Institute of Medical SciencesAcardiac malformation is a well-known complication of monozygotic twins. Pathogenesis involves the pumping of blood from a donor twin to an acardiac twin through its umbilical arteries anastomosing at the level of the placenta through abnormal ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Acardiac Twinning (Twin Reversed Arterial Perfusion Sequence): A Review of Prenatal Management
Taiwanese Journal of Obstetrics & Gynecology, 2005 Acardiac twinning, or the twin reversed arterial perfusion (TRAP) sequence, occurs in 1% of monozygotic twins, or 1 in 35,000 births. It is caused by the development of arterioarterial vascular anastomoses between the umbilical arteries of monozygotic ...
