Effects of Ultrashort Wave Therapy on Inflammation and Macrophage Polarization after Acute Lung Injury in Rats.

Bioelectromagnetics 2021 Jun 15. Epub 2021 Jun 15.

Rehabilitation Medicine Center, The First Affiliated Hospital of University of South China, Hengyang, People's Republic of China.

Acute lung injury (ALI) features dysregulated pulmonary inflammation. Ultrashort waves (USWs) exert anti-inflammatory effects but no studies have evaluated their activity in ALI. Herein, we used an in vivo lipopolysaccharide (LPS)-induced ALI model to investigate whether the anti-inflammatory activity of USWs is mediated by altering the polarization of M1 to M2 macrophages.

ROTEM Testing for Direct Oral Anticoagulants.

Semin Thromb Hemost 2021 Jun 15. Epub 2021 Jun 15.

Department of Internal Medicine I, Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, Martin, Slovak Republic.

Direct oral anticoagulants (DOACs) are increasingly used worldwide for the prevention of stroke in patients with atrial fibrillation and to prevent or treat venous thromboembolism. In situations such as serious bleeding, the need for urgent surgery/intervention or the management of a thromboembolic event, the laboratory measurement of DOACs levels or anticoagulant activity may be required. Rotational thromboelastometry (ROTEM) is a viscoelastic hemostatic assay (VHA) which has been used in emergencies (trauma and obstetrics), and surgical procedures (cardiac surgery and liver transplants), but experience with this assay in DOACs-treated patients is still limited.

The crucial role of heavy metals on the interaction of engineered nanoparticles with polystyrene microplastics.

Water Res 2021 Jun 1;201:117317. Epub 2021 Jun 1.

Department of Chemistry, Hong Kong Baptist University, Kowloon Tong, HKSAR, P.R.China; HKBU Institute of Research and Continuing Education, Shenzhen Virtual University Park, Shenzhen, P.R.China. Electronic address:

Despite continuous research on microplastics (MPs), studies exploring the complexity of interaction between MPs and other aqueous constituents in multi-solute systems are scarce. In this study, the uptake and release of nanoceria (CeNPs) by various polystyrene MPs (PSMPs) were investigated. Results showed that PSMPs in the presence of heavy metals (HMs) exhibited a substantially higher sorption affinity for isotropic charged CeNPs than PSMPs alone; this enhanced affinity was attributed to the formation of PSMP-HM-CeNP complexes.
