A murine model of hemorrhagic refractory shock showed improved post-resuscitation survival time with adjuvant cytosolic energy replenishment.
<h3>
Objective:</h3>
- Resuscitation of a patient with refractory hemorrhagic hypovolemic shock (HS) is difficult.
- HS is linked to severe reductions of cellular energy nucleotides, which can result in cardio-circulatory arrest and mortality.
- Vasopressors, most often norepinephrine, are typically briefly supplied to control a persistent hypotension that is not rectified by intensive resuscitation attempts in order to avert an impending cardio-circulatory arrest.
<h3>Method</h3>
The following five groups of 10 each were randomly assigned to 50 male Sprague-Dawley rats:
- HS/conventional resuscitation (CR), HS/CR+norepinephrine, HS/CR+vasopressin, HS/CR+vesicles, and HS/CR+ATPv.
- ATPv, which are highly fusogenic lipid vesicles encasing ATP, were used to directly replace the cytosol with ATP.
- Direct cytosolic ATP delivery is made possible by the instantaneous fusion of the ATPv with the cell membrane.
- The study's endpoint was established as the post-resuscitation survival period.
<h3>Results:</h3>
The SI and MAP showed that all animals experienced the same kind of shock. According to the long-rank Mantel-Cox test and Kaplan-Meier survival curves, the median post resuscitation survival periods were as follows: HS/CR+Nor epinephrine = 35.5 min; HS/CR+Vasopressin = 20 min; HS/CR+Lipid Vesicles control = 88.5 min; and HS/CR+ATPv = 158.5 min

Answer:
because sun is a gas and any astroids that hit it melts
Answer:<u> Products of respiration</u> are Carbon dioxide and water (and ATP)
The pressure at any level in the atmosphere may be interpreted as the total weight of the above unit
