Impact of Physical Interventions, Phosphorus Fertilization, and the Utilization of Soil Amendments on the Absorption of Cadmium by Lettuce Grown in a Solar-Powered Greenhouse.

This study aimed to evaluate the effects of physical measures and the applications of phosphorus fertilizer and soil conditioner on the growth of lettuce (Lactuca sativa) and its uptake of cadmium (Cd). In a solar greenhouse that contained soil enriched with cadmium (Cd) (1.75 ± 0.

pH-Responsive Amphiphilic Triblock Fluoropolymers as Assemble Oxygen Nanoshuttles for Enhancing PDT against Hypoxic Tumor.

Photodynamic therapy (PDT) is a cancer treatment strategy that utilizes photosensitizers to convert oxygen within tumors into reactive singlet oxygen (O) to lyse tumor cells. Nevertheless, pre-existing tumor hypoxia and oxygen consumption during PDT can lead to an insufficient oxygen supply, potentially reducing the photodynamic efficacy. In response to this issue, we have devised a pH-responsive amphiphilic triblock fluorinated polymer (PDP) using copper-mediated RDRP.

Effect of brackish water irrigation on cadmium migration in a soil-maize system.

Phytoremediation is an effective way to reduce heavy metal content in agricultural soil. The effects of brackish water irrigation on phytoremediation efficiency of plants have not yet been completely understood. In this study, the effects of brackish water irrigation on cadmium (Cd) uptake by maize as the phytoremediator were investigated.

[Analysis on volatile constituents of Semen Ziziphi Spinosae by HS-SPME-GC-MS].

Objective: To establish a rapid and simple method for the determination of volatile constituents in Semen Ziziphi Spinosae.

Methods: The volatile constituents in Semen Ziziphi Spinosae were extracted by head space solid-phase microextraction (HS-SPME) and analysed by GC-MS.

Results: Powder of sample was pre-heated for 30 min at 90 degrees C, then headspace-extracted with 65 microm PDMS/DVB fiber for 50 min.
