Serum lymphocytes and cytokines: diagnostic value and influence on the immune status in patients with pulmonary tuberculosis.

Objective: To determine the absolute number of serum T lymphocytes and cytokine levels and the characteristics of patients with active pulmonary tuberculosis and to assess their effect on the immune status of these patients and their diagnostic and predictive value for tuberculosis.

Methods: We included 1,069 patients with active tuberculosis, 51 patients with latent tuberculosis infection, and 600 health individuals. Absolute serum T-lymphocyte counts and cytokine levels were quantified.

Connection of Ru nanoparticles with rich defects enables the enhanced electrochemical reduction of nitrogen.

The electrochemical reduction of N into NH under ambient conditions is an attractive topic in the chemical industry, but the chemical inertness of N and the competing hydrogen evolution reaction hamper the activity and selectivity of this reaction. Herein, we connected Ru nanocrystals through a facile annealing process, which constructed intraparticle grain boundaries and stacking faults in the connection regions to enhance the N reduction reaction. The connected Ru nanoparticles exhibited an enhanced yield rate and faradaic efficiency for NH production.

Sulfur edge in molybdenum disulfide nanosheets achieves efficient uranium binding and electrocatalytic extraction in seawater.

Electrochemical extraction of uranium in seawater provides a promising strategy for the persistent supply of fuel in the nuclear industry. However, current operation voltage for the electrochemical extraction of uranium in seawater generally requires a high applied voltage (∼-5 V). Herein, we constructed S-terminated MoS nanosheets with abundant electrochemically active S-edge sites for efficient binding and reduction of uranium.

Synthesis of Uranium Single Atom from Radioactive Wastewater for Enhanced Water Dissociation and Hydrogen Evolution.

As a common nuclide in radioactive wastewater, uranium (U) is generally treated by landfill, which induces the massive abandonment of uranium resources. In this work, a pulse voltammetry method for the synthesis of U single atoms on MoS (U/MoS ) nanosheets from radioactive wastewater for the electrocatalytic alkaline hydrogen evolution reaction (HER) is reported. The mass loading of U single atoms is facilely controlled with high selectivity for coexisting ions in radioactive wastewater.
