Superefficient Removal of Heavy Metals from Wastewater by Mg-Loaded Biochars: Adsorption Characteristics and Removal Mechanisms.

Six types of biochar (BSB, CSB, FSB, CFSB, MSB, and TSB) were prepared from different raw materials by loading magnesium ions (Mg) via an impregnation process. The adsorption kinetics and thermodynamics of heavy metals at high concentrations were analyzed. The adsorption mechanisms were investigated by zeta potential, scanning electron microscopy-energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and inductively coupled plasma-atomic absorption spectroscopy analyses.

Apoptotic Cell Clearance in .

The swift clearance of apoptotic cells (ACs) (efferocytosis) by phagocytes is a critical event during development of all multicellular organisms. It is achieved through phagocytosis by professional or amateur phagocytes. Failure in this process can lead to the development of inflammatory autoimmune or neurodegenerative diseases.

Effects of inflammatory factors including plasma tumor necrosis factor-α in the clinical treatment of acute respiratory distress syndrome.

The present study investigated the association between the levels of plasma tumor necrosis factor-α (TNF-α), interleukin (IL)-6, IL-8, high-sensitivity C-reactive protein and fibrinogen levels of patients with acute respiratory distress syndrome (ARDS) with ARDS treatment outcome and duration of mechanical ventilation, with the aim of improving the efficacy of ARDS therapy. A total of 140 patients with ARDS were randomly divided into groups A and B, with 70 patients in each group. The patients in group A received a combination of conventional treatment and comprehensive treatment (test group) and the patients in group B were treated with conventional therapy only (control group).

[Different levels of nitric oxide in seminal plasma of fertile and abnormospermic men].

Objectives: To understand the relation between nitric oxide (NO) level in seminal plasma and male fertility.

Methods: The levels of NO in seminal plasma of 174 fertile males and 217 abnormospermia patients were measured by using the reductase of nitric acid, Greiss reagent and spectrophotometry.

Results: 1.

Helicobacter pylori HspA Heat-shock Protein Gene Cloning, Expression and Immunogenicity.

Helicobacter pylori is the causative agent of gastritis and peptic ulcer in human. The heat-shock protein A (HspA)may stimulate the immunoresponse protecting human body against challenge of H.pylori.
