The most frequent cause of hyperthyroidism in children is Graves' disease (GD). Vascular endothelium is a specific target of thyroid hormone. The purpose of this study is to assess flow-mediated dilatation (FMD)% and serum von Willebrand factor (vWF) levels in children with newly diagnosed GD to reflect the extent of endothelial dysfunction in those children.

This study aimed to assess whether urinary C-peptide creatinine ratio (UCPCR) might be a potential indicator of NAFLD in obese children.
Methods: The study included 240 children with simple obesity.
Different headspace condition has a great influence on fermentation process. In this study, whey protein was used as substrate, and the headspace air was changed in three different ways (H mixed N, H mixed CO, N with different sparging rates) to explore the effects of these three methods on products. The result showed that H mixed with CO is more conducive to acid production.

Flocculation can remove large amounts of nitrogen and phosphorus from wastewater, and the resulting nitrogen- and phosphorus-rich floc can be used to produce organic fertilizer. For biogas slurries containing high levels of nitrogen and phosphorus, ordinary flocculants can no longer meet the flocculation requirements. In this study, to fully utilize the advantages of the two flocculants and achieve efficient removal rates of nitrogen and phosphorus from a biogas slurry, chitosan (CTS) and polyaluminum chloride (PAC) were used as a composite flocculation agent to flocculate pig biogas slurries.

Objectives: This study was undertaken to investigate the role of cytokines involvement in pediatric patients with β-lactam hypersensitivity and to determine whether involvement of cytokines in drug-mediated reactions are important for the perspective of allergic patient's management.
Methods: β-lactam-induced hypersensitivity reactions in eighty pediatric patients were determined by clinical manifestations and skin prick or intradermal testing.
