Stability of 2-Alkylcyclobutanones in Irradiated Retort Pouch <i>Gyudon</i> Topping During Room Temperature Storage

The effect of room-temperature storage on the stability of compounds in DMSO.

The stability of approximately 7200 compounds stored as 20-mM DMSO solutions under ambient conditions was monitored for 1 year. Compound integrity was measured by flow injection analysis using positive and negative electrospray ionization mass spectrometry. Each sample was assessed at the beginning of the study, after 12 months of storage, and at a randomized time point between the initial and ...

Stability of meropenem in normal saline solution after storage at room temperature.

The bactericidal activity of meropenem is determined by the time that concentrations in tissue and serum are above the MIC for the pathogens during the dosing interval. Thus, the most effective mode of administering of meropenem is continuous infusion. However, the stability of meropenem reconstituted in solution is influenced by the storage temperature. Until now we have had no data to evaluat...

Chain and conformation stability of solid-state DNA: implications for room temperature storage

There is currently wide interest in room temperature storage of dehydrated DNA. However, there is insufficient knowledge about its chemical and structural stability. Here, we show that solid-state DNA degradation is greatly affected by atmospheric water and oxygen at room temperature. In these conditions DNA can even be lost by aggregation. These are major concerns since laboratory plastic ware...

Stability of blood gases in ice and at room temperature.

Arterial blood samples from 75 patients were analyzed for PO2, PCO2, and pH at 0, 15, and 30 min. After the baseline analysis, 60 samples were kept in ice while 59 samples were left at room temperature. There was a statistically significant increase in the PO2 at 15 min and again at 30 min in both groups. There was a statistically significant decrease in the PCO2 at 15 min in both groups. There...
