Risk of increasing soil nitrous oxide emissions by chemical oxidation modification on biochar.

Biochar is widely recognized as a soil amendment capable of mitigating soil nitrous oxide (NO) emissions. However, the effects of biochar modification, particularly through chemical oxidation, remain relatively unexplored. This study modified wood and corn straw biochars using HO and acid (HSO/HNO).

Lupiwighteone as an Antitumor Agent Reverses Multidrug Resistance in K562/ADR Cells by Regulating Cellular Prion Protein-Oct4 Axis.

Introduction: One of the many reasons for cancer treatment failure and recurrence is acquired Multidrug Resistance (MDR). Overcoming cancer drug resistance has been the focus of researchers' studies. Cellular prion protein (PrP) is a glycophosphatidylinositol-anchored cell-surface glycoprotein that has been implicated in tumor behavior, including proliferation, apoptosis, invasion, metastasis, and chemoresistance.

Impact of iron-modified biochars on soil nitrous oxide emissions: Variations with iron salts and soil fertility.

Nitrous oxide (NO) emissions from soils are a significant environmental concern due to their contribution to greenhouse gas emissions. Biochar has been considered as a promising soil amendment for its potential to influence soil processes. Iron modification of biochar has been extensively discussed for its ability to enhance adsorption of pollutants, yet its impact on mitigating soil NO emissions remains poorly understood.

Combined effects of biochar and biogas slurry on soil nitrogen transformation rates and NO emission in a subtropical poplar plantation.

It has been widely accepted that biochar has a great potential of mitigating soil nitrous oxide (NO) emission. However, the underlying mechanism about how biochar affects nitrogen transformation and the pathways of soil NO production is under discussion. A N-tracer incubation experiment was conducted to investigate the short-term effects of biochar on soil N transformation rates and source partitioning of NO emissions in soils from a poplar plantation system.

Pain and side effects associated with 4-dimensional hysterosalpingo-contrast sonography for evaluating of the fallopian tubes patency.

4-Dimensional hysterosalpingo-contrast sonography (4 D HyCoSy) using SonoVue is regarded as a really good option available for evaluating fallopian tubal patency. This study was designed to assess the pain and adverse effects incurred by women undergoing 4 D HyCoSy. Through evaluating the pelvic pain immediately after 4 D HyCoSy and 30 min after 4 D HyCoSy, the circumstances of the pain relief was also observed.
