Interleukin-33: Expression, regulation and function in adipose tissues.

Interleukin-33 (IL-33) is a pleiotropic cytokine of the IL-1 family that plays a key role in innate and adaptive immune responses and contributes to tissue homeostasis. Its role in adipose tissue function has been extensively studied, as adipose tissue serves as an important mediator of metabolic dysfunction. In adipose tissue, IL-33 is primarily produced by stromal cells.

IL-33 promotes pancreatic β-cell survival and insulin secretion under diabetogenic conditions through PPARγ.

Pancreatic β-cell dysfunction plays a vital role in the development of diabetes. IL-33 exerts anti-diabetic effects via its anti-inflammatory properties and has been demonstrated to increase insulin secretion in animal models. However, IL-33, as a pleiotropic cytokine, may also exert a deleterious effect on β-cells, which has not been rigorously studied.

Improved power generation using nitrogen-doped 3D graphite foam anodes in microbial fuel cells.

The properties of the anode material and structure are critical to the microbial growth and interfacial electron transfer between the biofilm and the anode. In this paper, we prepared the nitrogen-doped 3D expanded graphite foam (NEGF) by simple, rapid and inexpensive methods of liquid nitrogen expansion and hydrothermal treatment from commercial graphite foil (GF). X-ray photoelectron spectroscopy confirmed the success of nitrogen doping on expanded graphite foam (EGF).
