Albalá-Hurtado et al. [4] investigated the formation of HMF as a result of exposure to different storage temperatures (20, 30, 37 °C) and storage duration (up to 9 months) in liquid as well as in powdered infant milk.
As well, VRC-containing tablets are imported from outside of many countries, consequently there is a major concern about its quality after exposure to transportation, storage, and other conditions.
Gels were fixed for 30 min at room temperature in 40% methanol, 10% acetic acid, and 5% glycerol, followed by incubation in Amplify Fluorographic Reagent (GE Healthcare), gel drying and exposure to phosphor storage screens (Molecular Dynamics).
They were subsequently checked by exposure to a storage phosphor screen to ensure complete removal of all radiolabelled probe, and re-probed as necessary.
The blot was visualized by exposure to a Storage Phosphor Screen (Amersham Biosciences, Piscataway, NJ) which was then scanned using a Storm 840 imaging system (Amersham Biosciences).
Ancient scriptures dating back to around 2000 BC highlight various practices of water treatment by filtration, exposure to sunlight and storage in brass and copper vessels [ 11].
Several places also have substantial local exposure to contaminants through storage of PCB oils from former military complexes and industrial waste (11, 36).
Hysteresis increased in samples snap frozen at -196°C and stored at -80°C, though remained unchanged with exposure to the other storage temperatures.
A key finding from this study is that appropriate packaging with aluminum over and under the misoprostol tablets (versus use of aluminum and plastic) is critical to its stability by preventing exposure to humidity during storage of the drug.
A robust physical stability has also been demonstrated in indomethacin-PHEMA ASD by using polarized light microscopy to detect the onset of drug precipitation and no drug precipitation was observed for up to 8 months under direct exposure to an accelerated storage condition (40 °C/75% RH) for indomethacin loading levels below 16.7% w/ w.
