Mass spectrometry based identification of AMP‐O‐Tris generated by Thermococcus onnurineus Cas10

FEBS Open Bio, EarlyView.
Isolated Thermococcus onnurineus Cas10 generates the noncanonical ATP‐derived product AMP‐O‐Tris while in Tris‐containing buffer as identified via mass spectrometry, revealing relaxed nucleophile selectivity under isolated conditions. These findings suggest that multiprotein Csm complex assembly restricts Cas10 reactivity toward canonical cyclic ...

Measurement of core losses in toroidal inductors with different magnetic materials [PDF]

, 2017
Magnetic materials are used in the manufacturing of transformers, electrical machines, converters and inductors. The losses of the magnetic materials affect the performance of the electromagnetic devices. The magnetic components play an important role in

Blood‐based proteomic profiling reveals context‐dependent changes in BCL2‐associated signaling during taxane therapy in breast cancer patients

FEBS Open Bio, EarlyView.
Chemotherapy side effects significantly impact cancer survivors' quality of life. Using protein levels in blood samples from breast cancer patients before and after 12 weeks of taxane treatment, we detected treatment‐dependent changes in calcium signaling and aging pathways associated with cancer recurrence.

Minimising losses of nitrogen from UK agriculture

, 2004
The nitrogen cycle is essentially ‘leaky’. Small amounts of nitrate must leach into waters, and ammonia and nitrous oxide be emitted to the atmosphere to maintain natural ecosystems. However, in many parts of the world, intensive agricultural production

Magnetic core effects on the high-frequency behavior of transformers

International Journal of Electrical Power & Energy Systems
This paper investigates the high-frequency transformer losses attributed to eddy currents in both conductors and the core. A comprehensive model of a transformer winding is presented, meticulously incorporating skin and proximity effects.

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

FEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Influence of Losses on the Output Voltage of Ferrite Transformer in Case of Strong Magnetic Field in the Core

Taking into account the nonlinear properties of ferrites the output voltage of toroidal transformer with magnetically soft ferrite core is calculated. Calculations are based on methods analogous to those used in nonlinear optics.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

High-Frequency Model of the Toroidal Powder Core and Winding of a Litz Wire

Energies
A high-frequency model of the toroidal powder core inductor with litz wire winding is presented. In the analyzed model, the power losses that occurred in both the winding and the magnetic core were taken into account.
