Abstract:
... Hepatocellular carcinoma (HCC) is associated with poor prognosis due to many unknowns about its inflammatory microenvironment. As a pivotal proinflammatory cytokine, IL-17A exerts a protective effect on the survival and function of HCC cells. It is widely accepted that IL-17A plays an important role in regulating autophagy. Bcl2, a key molecule promoting the survival of HCC cells, also plays an in ...

Abstract:
... Side-stream sludge treatment using free nitrous acid (FNA) is a novel strategy to achieve nitritation in mainstream of wastewater treatment plants (WWTPs). To optimize nitritation, the effect of starvation on this strategy was investigated in this study. The results showed that pre-starvation, which is the starvation before FNA treatment, enhanced the resistance of sludge to FNA. This led to a dec ...

Abstract:
... To understand the function of DGTS (diacylglyceryl-N,N,N-trimethyl-homoserine) as substitution of PC (phosphatidylcholine), Nannochloropsis oceanica has been chosen as the model system because it has DGTS and PC simultaneously. Phosphorus is a regulator for DGTS and PC. Generally, DGTS increases and correspondingly PC decreases under phosphorous starvation. However, the function of DGTS and its fa ...

Although current guidelines for obesity treatment endorse lifestyle modifications to achieve weight loss, energy-restricted diets are still the most commonly used method for the management of overweight. Diet restriction, however, not only is ineffective in promoting long-term weight loss but also may have more costs than benefits, predisposing the individual to fat regain. Several physiological a ...
