Journal ArticleDOI
New materials in solid-phase microextraction
TL;DR: A review of the most commonly used coating materials for solid phase microextraction (SPME) in the past five years can be found in this paper, where the authors discuss ionic liquids (ILs), polymeric ILs, graphene, carbon nanotubes, molecularly imprinted polymers and metal-organic frameworks.
Journal ArticleDOI
Newly diagnosed diabetes is associated with a higher risk of mortality than known diabetes in hospitalized patients with COVID-19.

TL;DR: To evaluate the association between different degrees of hyperglycaemia and the risk of all‐cause mortality among hospitalized patients with COVID‐19, a large number of patients were randomly assigned to receive either a high or a low dose of COVID.
Journal ArticleDOI
Metformin ameliorates hepatic steatosis and inflammation without altering adipose phenotype in diet-induced obesity.
Shih Lung Woo,Hang Xu,Honggui Li,Yan Zhao,Xiang Hu,Xiang Hu,Jiajia Zhao,Jiajia Zhao,Xin Guo,Ting Guo,Rachel Botchlett,Ting Qi,Ya Pei,Juan Zheng,Juan Zheng,Yiming Xu,Xiaofei An,Lulu Chen,Lili Chen,Qifu Li,Xiaoqiu Xiao,Yuqing Huo,Yuqing Huo,Chaodong Wu +23 more
TL;DR: It is suggested that metformin protects against obesity-associated NAFLD largely through direct effects on decreasing hepatocyte fat deposition and on inhibiting inflammatory responses in both hepatocytes and macrophages.
Journal ArticleDOI
Fabrications of novel solid phase microextraction fiber coatings based on new materials for high enrichment capability
Juan Zheng,Junlong Huang,Qian Yang,Chuyi Ni,Xintong Xie,Yueru Shi,Jingfang Sun,Fang Zhu,Gangfeng Ouyang +8 more
TL;DR: In this paper, a review summarizes the used materials for the fabrication of SPME coatings in the past five years, including carbon, polymer, metal organic frameworks (MOFs), covalent organic framework (COFs), ionic liquids (ILs), metal/metal oxide nanoparticles and silica.
Journal ArticleDOI
GABA promotes human β-cell proliferation and modulates glucose homeostasis
Indri Purwana,Juan Zheng,Xiaoming Li,Marielle Deurloo,Dong Ok Son,Zhaoyun Zhang,Christie Liang,Eddie Shen,Akshaya Tadkase,Zhong-Ping Feng,Yiming Li,Craig P. Hasilo,Steven Paraskevas,Rita Bortell,Dale L. Greiner,Mark A. Atkinson,Gerald J. Prud'homme,Qinghua Wang +17 more
TL;DR: It is suggested that GABA regulates human β-cell mass and may be beneficial for the treatment of diabetes or improvement of islet transplantation.
