Transporting Cells in Semi-Solid Gel Condition and at Ambient Temperature

Transporting Cells in Semi-Solid Gel Condition and at Ambient Temperature

Mammalian cells including human cancer cells are usually transported in cryovials on dry ice or in a liquid nitrogen vapor shipping vessel between different places at long distance. The hazardous nature of dry ice and liquid nitrogen, and the associated high shipping cost strongly limit their routine use. In this study, we tested the viability and properties of cells after being preserved or sh...

Preparation and evaluation of geopolymer composites containing alumina particles at ambient temperature and after heating

In this research, geopolymer composites were prepared using metakaolin along with silica fume and potassium hydroxide as alkaline activators and alumina particles. The effect of alumina particle size to achieve castable microstructure and their mechanical properties were investigated. Different Si:Al mole ratio (1.5, 2, 2.5 and 3) and K:Si mole ratio (0.20, 0.25, 0.33) were formulated and the s...

Encapsulation of Viscous High-Fat Foods in Calcium Alginate Gel Tubes at Ambient Temperature

Etanercept (Enbrel®) alternative storage at ambient temperature

BACKGROUND Biologic disease-modifying antirheumatic drugs, including tumor necrosis factor inhibitors such as etanercept (Enbrel®), have improved outcomes for patients with rheumatic and other inflammatory diseases, with sustained remission being the optimal goal for patients with rheumatoid arthritis. Flexible and convenient treatment options, compatible with modern lifestyle, are important in...

Versatile gold catalyzed transglycosidation at ambient temperature.

Glycosidation with stable alkyl glycosyl donors using a catalytic amount of gold salts is promising. Herein, 1-ethynylcyclohexanyl glycosides are identified as novel donors at room temperature and mechanistic investigation showed that the leaving group simply extrudes out.
