Immobilization or mobilization of heavy metal(loid)s in lake sediment-water interface: Roles of coupled transformation between iron (oxyhydr)oxides and natural organic matter.

Iron (Fe) (oxyhydr)oxides and natural organic matter (NOM) are active substances ubiquitously found in sediments. Their coupled transformation plays a crucial role in the fate and release risk of heavy metal(loid)s (HMs) in lake sediments. Therefore, it is essential to systematically obtain relevant knowledge to elucidate their potential mechanism, and whether HMs provide immobilization or mobilization effect in this ternary system.

Hubbard Gap Closure-Induced Dual-Redox Li-Storage Mechanism as the Origin of Anomalously High Capacity and Fast Ion Diffusivity in MOFs-Like Polyoxometalates.

MOFs-like polyoxometalate (POMs) electrodes, harvesting combined advantages of interlocking porosity and multi-electron transfer reaction, have already emerged as promising candidates for lithium-ion batteries (LIBs), yet the origins of the underlying redox mechanism in such materials remain a matter of uncertainty. Of critical challenges are the anomalously high storage capacities beyond their theoretical values and the fast ion diffusivity that cannot be satisfactorily comprehended in the theory of crystal lattice. Herein, for the first time we decode t electron occupation-regulated dual-redox Li-storage mechanism as the true origin of extra capacity in POMs electrodes.

Synergy of Pd/S-Doped TiO Supported on 2-Methylimidazolium-Functionalized Polypyrrole/Graphene Oxide for Enhanced Nitrogen Electrooxidation.

The electrosynthesis of nitrate catalyzed by electrochemical nitrogen oxidation reaction (NOR) is considered as an alternative and sustainable approach to the conventional industrial manufacture, but optimizing the electrocatalytic NOR performance and fabricating the efficient NOR electrocatalysts at the design level still encounter great challenges. Herein, unique Pd- and S-doped TiO (Pb/S-TiO) nanoparticles are successfully in situ grown on the surface of 2-methylimidazolium-functionalized polypyrrole/graphene oxide (2-MeIm/PPy/GO), which present the typical hierarchical micro-nanostructures, resulting in the excellent electrocatalytic NOR performance with the highest NO yield of 72.69 µg h mg and the maximum Faraday efficiency of 8.

Utilization of Lemon Peel for the Production of Vinegar by a Combination of Alcoholic and Acetic Fermentations.

Lemon peel is the major by-product of lemon juice processing and is currently underutilized. In this study, we explored the feasibility of using lemon peel as a raw material for making vinegar. Lemon peel was homogenized, treated with pectinase (30,000 U/g, 0.

AT2 cell-derived IgA trapped by the extracellular matrix in silica-induced pulmonary fibrosis.

Pulmonary fibrosis is an interstitial lung disease caused by various factors such as exposure to workplace environmental contaminants, drugs, or X-rays. Epithelial cells are among the driving factors of pulmonary fibrosis. Immunoglobulin A (IgA), traditionally thought to be secreted by B cells, is an important immune factor involved in respiratory mucosal immunity.

Pseudo-Thrombotic Microangiopathy Secondary to Vitamin B12 Deficiency.

Background: Clinical B deficiency with hematological or neurological manifestations is rare. An unusual manifestation of B deficiency is pseudo-thrombotic microangiopathy (TMA), which is characterized by hemolytic anemia, thrombocytopenia, and schistocytosis and only occurs in 2.5% of those with B deficiency.

A pharmacoeconomic assessment of recombinant tissue plasminogen activator therapy for acute ischemic stroke in a tertiary hospital in China.

Objectives: To conduct a pharmacoeconomic assessment of thrombolysis by intravenous recombinant tissue plasminogen activator (rt-PA) therapy for acute ischemic stroke (AIS) in 6 hours in a tertiary hospital in China.

Materials And Methods: A retrospective analysis was conducted using medical records data among patients hospitalized for AIS and receiving treatment with or without rt-PA (6 hours after AIS) from January 2006 to December 2008. The conservative therapy group was matched (1∶1) on age, gender, risk factors, Glasgow Coma Scale, and National Institutes of Health Stroke Scale (NIHSS).

The long-term outcome of carotid artery stenting or antiplatelet therapy in patients with severe carotid artery stenosis.

Objective: To identify the prognosis factors of the patients with high-degree carotid artery stenosis and evaluate the effects of carotid artery stenting and antiplatelet therapy prospectively.

Methods: Patients with severe carotid artery stenosis were enrolled in this study consecutively. Intervention was carotid artery stenting combined with antiplatelet therapy or antiplatelet therapy solely.

[Level of plasma lysophosphatidic acid in patients with cerebral ischemic attack, a preliminary study].

Objective: To study the level of plasma lysophosphatidic acid (LPA) in patients with TIA, cerebral thrombosis or possible ischemic attack.

Methods: Phospholipid was extracted from plasma of patients with TIA, cerebral thrombosis or possible ischemic attack by organic solvent. Lysophosphatidic acid was isolated further.
