Summary: This study investigated the remediation of arsenic-contaminated abandoned mine soils. Oxalic acid was found to be the most effective washing reagent. Washing reduced the leachability and bioaccessibility of arsenic and iron in the treated soil, but it still exceeded the remediation criteria. Soil washing and subsequent solidification/stabilization could be an alternative option for remediating extremely contaminated abandoned mine soils.

Summary: This study successfully removed zinc from heavy metal contaminated soils using a two-step washing method with citric acid and water-soluble chitosan, significantly decreasing the total concentration of zinc in the soil, particularly in the carbonate-bound fraction. The washing mechanism may involve acid dissolution, ion exchange, and complexation reactions between zinc ions and functional groups like hydroxyl, carboxyl, amine, and amide groups. This research provides theoretical support for the development and application of suitable washing agents for the remediation of heavy metal contaminated soils.

Summary: Soil washing using FeCl3 was effective in reducing heavy metal concentrations, particularly for Pb, with the lowest concentrations achieved with a 1 M FeCl3 washing solution. However, the reduction in Cu and Zn was limited due to their initial concentrations being below regulatory standards. Sequential extraction results showed significant reductions in exchangeable and weak acid-soluble fractions of Pb upon FeCl3 washing.

Summary: This paper presents a methodical strategy for efficient remediation of oil spill from contaminated marine intertidal zone surface using biosurfactant mediated washing. The study focuses on the production, optimization, and application of lipopeptide biosurfactant from Bacillus subtilis T1 in different marine intertidal zones. The results demonstrate enhanced washing performance and oil desorption rate, with the highest rate observed in the mudflats group. Kinetic validation shows good agreement between experimental data and the pseudo second-order kinetics.

Summary: Ethylenediaminetetraacetic acid (EDTA) is commonly used to clean heavy metal contaminated fields, especially those with low-permeability zones rich in clays. This study investigated the release kinetics of cations from clayey sediments during EDTA elution and the mechanisms controlling cation release. The results showed that EDTA greatly enhanced the release of cations from clays, with more interlayer cations being brought out via complexation and structural cations being released due to the breaking of metal-oxygen bonds. The first-order release rate constants of structural cations were slower than those of interlayer cations, indicating slower mineral dissolution.

Summary: An innovative thermal desorption method called propylene glycol (PG)-mixed steam enhanced extraction is proposed for efficient remediation of PAHs-contaminated soil. Injecting PG-mixed steam into soil can achieve over 99% removal efficiencies of PAHs. The recovered PG solution after coagulation treatment can be reused, and the remediated soil shows good regreening potential.

Summary: This paper used Tween 80 to assist in ex-situ washing of ciprofloxacin-contaminated soil and found that 2 g/L of Tween 80 was the most effective in removing the contaminant. The collected soil washing effluent was then electrochemically treated, and it was found that ciprofloxacin was usually degraded within 30 minutes, while 50% of Tween 80 remained at the end of the experiment. LC-MS analysis showed that ciprofloxacin was mainly degraded synergistically by ·OH and active chlorines, and ·OH effectively reduced the biotoxicity of the washing effluent.

Summary: This study evaluated the use of ethylenediamine N,N'-disuccinic acid (EDDS) and 3-hydroxy-2,2'-imino disuccinic acid (HIDS) as alternatives to ethylenediaminetetraacetic acid (EDTA) for treating arsenic-contaminated excavated soil. The effectiveness of chelators in removing arsenic was optimized by adjusting various washing variables. Additionally, methods for immobilizing eluted arsenic and suppressing subsequent leaching were assessed.

Chelator-assisted washing using biodegradable chelators such as EDDS, GLDA, and HIDS has shown promise as a viable treatment option. FeCl3 and CaO can be used as post-treatment to immobilize residual lead. This study provides a practical remediation strategy for extracting lead from soil and reducing leaching potential.

Summary: Medicine/nanotechnology is gaining great attention as a new and applicable technique for cancer treatment through drug delivery systems. Polysaccharides, such as cellulose, beta-cyclodextrin, sodium carboxymethyl cellulose, and chitosan, are natural bio-materials that are suitable for designing and formulating nanosystems due to their exceptional advantages. An intelligent drug delivery platform based on these hybrids has been developed for dual-responsive dual-drug delivery. The combination of nanotechnology and biological molecules has been actively explored to overcome the limitations of conventional cancer treatments. This review discusses and investigates the latest developments in the field of biomedical therapeutics and cancer therapy using hybrid platforms of anticancer drugs/nanoparticles/Polysaccharides, highlighting their biocompatibility, large surface area, and promising future prospects.

Summary: This post-hoc analysis of the RADIANCE-HTN SOLO study found that predictors of response to renal denervation (RDN) included higher baseline daytime ambulatory diastolic blood pressure and use of antihypertensive medications, with orthostatic hypertension potentially predicting response. Obese females also appeared to have a better response to RDN in an interaction model.

Summary: A one-pot co-pyrolysis strategy using potassium/calcium carbonate and biowaste-derived hydrochar was proposed to prepare hierarchical porous biochars (HPBs). The pore structure of HPBs could be controlled by adjusting the mass ratios of different carbonates. HPBs exhibited hydrophobicity, nitrogen doping, graphitization, and surface functional groups, and showed unexpectedly high sorption quantity for diethyl phthalate. The sorption mechanisms were identified as Lewis acid-base interaction, pi-pi stacking interaction, hydrogen bonding interaction, partitioning, and pore filling.

Summary: This study determined the residual concentrations and bioaccessibility of PAHs in soils from two industrial sites. The results showed heavy PAH contamination, with high molecular weight PAHs accounting for a significant portion. The bioaccessibility of certain PAH compounds decreased with increasing ring number. Soil properties such as dissolved organic matter, total organic carbon, total potassium, and total manganese concentrations had significant effects on the bioaccessibility of PAHs.

Summary: In this study, a liposome decorated with platelet membrane was developed to enhance the specific tumor-targeting capability and antitumor responses of photodynamic therapy (PDT) in breast cancer treatment. The results showed that the platelet membrane-decorated liposome could effectively improve the cellular internalization of the loaded drug and generate sufficient reactive oxygen species (ROS) to inhibit tumor growth. The study provides a biomimetic strategy to improve the therapeutic efficacy of PDT in breast cancer.
