Background: Immune cells perform unique functions against infections and imbalances in immunity associated with various diseases. Applying natural products may control immune responses. Among herbals, much attention has been paid to the immunoregulatory functions of Allium sativum. However, the effects of other Allium species on the immune system have remained undiscovered. Therefore, the curre...

The reaction of CH₃NH₂ with O₂ on the singlet potential energy surfaces (PES) was carried out using the B3LYP, CCSD(T) and G3B3 theoretical approaches along with 6-311++G(3df,3pd) basis set. The suggested mechanism for the title reaction consists of one pre-reactive complex. From the pre-reactive complex, nine types of products, CH2NH+H2O2, CH3NH+OOH,...

Phase transitions are abrupt changes in the macroscopic properties of a system. Examples of the phenomenon are familiar: freezing, condensation, magnetization. Often these transitions are particularly dramatic, as when solid objects composed of the silvery metal gallium vanish into puddles when picked up (the temperature of the hand is just enough to raise gallium’s temperature past its melting...
