Intervention
CDA, COLD
As part of the standard of care, all livers were preserved by static cold storage following classic organ procurement. All liver grafts were flushed with 1 L of Institut Georges Lopez (IGL-1) preservation solution through the portal vein ex situ at the end of the back-table preparation at the recipient center.

The primary end point was defined as the difference between the 2 study arms in peak serum aspartate aminotransferase (AST) levels within the first 72 hours after graft reperfusion, an accepted clinical surrogate of liver IRI that correlates with patient and graft survival and postreperfusion liver histological assessm...

Limitations
CDA
This study has some limitations. First, it was a single-center RCT. Second, individual effects of each component of the CDA in decreasing IRI were not assessed separately.

Conclusions
CDA, COLD
In this RCT, we did not find evidence that a combined drug approach targeting the post–cold storage graft and the recipient was sufficient to decrease IRI. Targeting the graft before and/or during preservation may also be necessary. The advent of dynamic preservation may bring the opportunity to combine a downstream CD...

Aim

The purpose of this study was to determine whether a low-tremor side-bridge exercise for 4 weeks improves bow tremor during archery movements.
PMC10150967
Methods
tremor
Participants were 20 male college students. First, we measured the tremor during side bridges performed with trunk inclinations of 25°, 40°, 55°, and 70° using an accelerometer attached to the elbow joint and identified low-tremor side bridges. The participants were then randomly divided into intervention and non-inter...

Results
tremor
The effect of the intervention was determined by measuring the total tremor value using an accelerometer attached to the bow and changes in the median power frequency (MdPF) of the middle deltoid, upper trapezius, and lower trapezius. This intervention reduced the bow tremor and the median power frequency of the middle...

Conclusions

The findings suggested that the tremor during the archery sighting phase could be reduced by performing side bridges with a specific trunk angle for a certain period of time.
