Pyrogenic Black Carbon Suppresses Microbial Methane Production by Serving as a Terminal Electron Acceptor.

Methane (CH) is the second most important greenhouse gas, 27 times as potent as CO and responsible for >30% of the current anthropogenic warming. Globally, more than half of CH is produced microbially through methanogenesis. Pyrogenic black carbon possesses a considerable electron storage capacity (ESC) and can be an electron donor or acceptor for abiotic and microbial redox transformation.

Treatment Outcomes and Effects of Ethanol Sclerotherapy on Systemic Coagulation Profile of Patients with Venous Malformation.

Background: Venous malformations (VMs) and sclerotherapy may disrupt the normal systemic coagulation profile in individuals. This study investigated a correlation between the clinical efficacy of sclerotherapy in the treatment of VMs and the changes in coagulation indexes to provide data that will inform the future application of this therapy.

Methods: From September 2019 to September 2020, 61 patients were enrolled in this study to receive sclerotherapy with absolute alcohol.

Multidimensional Assessment of Asthma Identifies Clinically Relevant Phenotype Overlap: A Cross-Sectional Study.

Background: Asthma is a heterogeneous disease with multiple phenotypes; however, the relevance of phenotype overlap remains largely unexplored.

Objective: To examine the relationship between phenotype overlap and clinical and inflammatory profiles of asthma.

Methods: In this cross-sectional study, adult participants with stable asthma (n = 522) underwent multidimensional assessments.

Localized intravascular coagulation in venous malformations: A system review.

Venous malformation is one of the slow-flow vascular malformations. Dysfunction of coagulation often occurs in most venous malformations, especially the diffuse and multifocal lesions, referred to as localized intravascular coagulopathy. It is characterized by the elevation of D-dimers and fibrin degradation products, low levels of fibrinogen, FV, FVIII, FXIII, and antithrombin III, and sometimes minor-to-moderate thrombocytopenia.

The adsorption characteristics of fluoride on commercial activated carbon treated with quaternary ammonium salts (Quats).

Commercial activated carbon was treated with six quaternary ammonium salts (Quats), namely, hexyltrimethylammonium (HTMA), octyltrimethylammonium (OTMA), decyltrimethylammonium (DCTMA), dodecyltrimethylammonium (DDTMA), Tetradecyltrimethylammonium (TDTMA), and hexadecyltrimethylammoium (HDTMA) as to enhance the fluoride adsorption capacity. In batch mode experiments, fluoride adsorption onto the Quats-treated activated carbon decreased dramatically with increase in solution pH. Fluoride removal by the Quats-treated activated carbons was closely related to the Quats chain length at less-than critical micelle concentration (CMC).

Highly efficient arsenic removal using a composite of ultrafine magnetite nanoparticles interlinked by silane coupling agents.

Arsenic (As) contamination in groundwater is a great environmental health concern and is often the result of contact between groundwater and arsenic-containing rocks or sediments and from variation of pH and redox potentials in the subsurface. In the past decade, magnetite nanoparticles (MNPs) have been shown to have high adsorption activity towards As. Alerted by the reported cytotoxicity of 5–12 nm MNP, we studied the adsorption behavior of 1.
