Reusable and effective polyacrylic membranes for mecoprop and bentazon extractions

This study introduces reusable polyacrylic membranes, fabricated from commercially available monomers (1-vinyl-2-pyrrolidone and methylmethacrylate), as a promising approach for pesticide extraction. These membranes effectively remove the commonly used herbicides mecoprop (RE ≈ 99%) and bentazon (RE ≈ 95%) at low concentrations, which pose water contamination risks due to their water-soluble prope

Insights on macro- and microscopic interactions between Confidor and cyclodextrin-based nanosponges

Imidacloprid is one of the most widely used soluble neonicotinoid insecticide, which is non–volatile and persists in the soil, with hazardous effects on birds, honeybees, and mammals. It is used in both agricultural and veterinary applications, and is found in at least 7% of European topsoils. One of the commercially available formulations is Confidor O–TEQ® that exhibits higher retention, spreadi

Straightforward purification method for the determination of the activity of glucose oxidase and catalase in honey by extracting polyphenols with a film-shaped polymer

Glucose oxidase (GOX) and catalase (CAT) regulate the amount of H2O2 in honey, by generating or consuming it, so they are related to the antibacterial and antioxidant activity of honey. However, their activities are hardly analysed, since the process requires a previous dialysis that is non-selective, very time-consuming (>24 h), eco-unfriendly (>6L of buffer) and expensive. This research shows th

Synthesis of β-cyclodextrin-based nanosponges for remediation of 2,4-D polluted waters

Two cyclodextrin-based nanosponges (CD-NSs) were synthesized using diamines with 6 and 12 methylene groups, CDHD6 and CDHD12, respectively, and used as adsorbents to remove 2,4-D from aqueous solutions. The physico-chemical characterization of the CD‒NSs demonstrated that, when using the linker with the longest chain length, the nanosponges show a more compact structure and higher thermal stabilit

Cyclodextrin-Based Nanosponges : Overview and Opportunities

Nanosponges are solid cross-linked polymeric nano-sized porous structures. This broad concept involves, among others, metal organic frameworks and hydrogels. The focus of this manuscript is on cyclodextrin-based nanosponges. Cyclodextrins are cyclic oligomers of glucose derived from starch. The combined external hydrophilicity with the internal hydrophobic surface constitute a unique “microenviron

Amine-β-cyclodextrin-based nanosponges. The role of cyclodextrin amphiphilicity in the imidacloprid uptake

This paper describes the synthesis, characterization and sorption performance of cyclodextrin nanosponges (NSs). Cyclodextrins are cyclic oligosaccharides with remarkable amphiphilic properties, allowing for a vast range of applications. The synthesis of nanosponges of β-cyclodextrins was carried out using two uncommon cross-linkers: hexane-1,6-diamine (am6) and dodecane-1,12-diamine (am12). It ha

Effect of cobalt and chromium ions on the chlorhexidine digluconate as seen by intermolecular diffusion

Metal ions such as cobalt (II) and chromium (III) might be present in the oral cavity, as a consequence of the corrosion of Co-Cr dental alloys. The diffusion of such metal ions into the organism, carried by saliva, can cause health problems as a consequence of their toxicity, enhanced by a cumulative effect in the body. The effect of the chlorhexidine digluconate, which is commonly used in mouthw

Poly(β-cyclodextrin)-activated carbon gel composites for removal of pesticides from water

Pesticides are widely used in agriculture to increase and protect crop production. A substantial percentage of the active substances applied is retained in the soil or flows into water courses, constituting a very relevant environmental problem. There are several methods for the removal of pesticides from soils and water; however, their efficiency is still a challenge. An alternative to current me

Transport properties of aqueous solutions of the oncologic drug 5-fluorouracil : A fundamental complement to therapeutics

Cancer pharmacology is often markedly toxic and must be precisely dosed in order to reach the therapeutic bioavailability under strict control. Transport properties are important tools in the process of interpretation and fine-tuning pharmaceutical applications, notably for drugs that have a long record of use and have met their limits of bioavailability. 5–Fluorouracil (5-FU) is one of the most u

Limiting diffusion coefficients of glufosinate ammonium, cymoxanil and imidacloprid in aqueous solutions

We have measured the limiting diffusion coefficients of three different pesticides in aqueous solutions: glufosinate ammonium, cymoxanil and imidacloprid, highly used for tomato production. The experiments were carried in aqueous solutions, at 25 °C, at concentrations below 3 mmol dm−3 (depending on the solubility of pesticides). Mutual diffusion coefficients (D) obtained by using the Taylor dispe

High temperature sensitivity of Arctic isoprene emissions explained by sedges

It has been widely reported that isoprene emissions from the Arctic ecosystem have a strong temperature response. Here we identify sedges (Carex spp. and Eriophorum spp.) as key contributors to this high sensitivity using plant chamber experiments. We observe that sedges exhibit a markedly stronger temperature response compared to that of other isoprene emitters and predictions by the widely accep

Futuristic Technology for Sustainable Manufacturing

In the manufacturing industry, a major concern persists—the historical entanglement of this sector with environmental issues. Climate change and resource depletion cast a shadow over traditional practices, demanding a paradigm shift. As our planet grapples with these challenges, the imperative for sustainable manufacturing practices becomes undeniable. Futuristic Technology for Sustainable Manufac

Introduction to Cyclodextrin-Based Nanosponges

Although cyclodextrins have been discovered over 130 years ago, they have been in the spotlight of researchers in academia and industry in the last 5–6 decades. That arises as a consequence of their unique physicochemical properties. This chapter starts with a historical overview of cyclodextrins, landmarks, and their properties and applications. The latter rest on the ability of cyclodextrins to

No title

Cyclodextrins are oligosaccharides with a wide range of applications since the last decades of the 20th century, although their discovery occurred at the end of the 19th century. Due to their donut-like structure and, essentially, their amphiphilic characteristics, cyclodextrins make it possible to modify the physicochemical properties of many compounds through the formation of supramolecular comp

Ultrahypofractionated Radiation Therapy for Prostate Cancer Including Seminal Vesicles in the Target Volume : A Treatment-planning Study Based on the HYPO-RT-PC Fractionation Schedule

Purpose: Ultrahypofractionated (UHF) radiation therapy (RT) has become a treatment alternative for patients with localized prostate cancer. In more advanced cases, seminal vesicles (SVs) are routinely included in the target volume. The Scandinavian HYPO-RT-PC trial, which compared 42.7 Gy in 7 fractions (fr) to conventional fractionation (CF), did not include SVs in the clinical target volume. The

MicroRNA 29 modulates β-cell mitochondrial metabolism and insulin secretion via underlying miR-29-OXPHOS complex pathways

Aim: MicroRNAs (miRNAs) regulate β-cell function, and β-cell mitochondria and insulin secretion are perturbed in diabetes. We aimed to identify key miRNAs regulating β-cell mitochondrial metabolism and novel β-cell miRNA-mitochondrial pathways. Methods: TargetScan (http://www.targetscan.org/) was used to predict if 16 miRNAs implicated in β-cell function target 27 cis-eGenes implicated in mitochon

ESTRO clinical practice guideline : Stereotactic body radiotherapy for spine metastases

Background and purpose: Recent progress in diagnostics and treatment of metastatic cancer patients have improved survival substantially. These developments also affect local therapies, with treatment aims shifting from short-term palliation to long-term symptom or disease control. There is consequently a need to better define the value of stereotactic body radiotherapy (SBRT) for the treatment of

Integrated Assessment of Climate Change and Forest Management Impacts on Carbon Fluxes and Biomass in a Southern Boreal Forest

Boreal forests play a crucial role in global carbon sequestration and storage, yet their vulnerability to climate change remains a significant concern. We present results from simulations with the process-based dynamic global vegetation model LPJ-GUESS of the combined effects of climate change and forest management on the carbon sink capacity of a boreal forest in southern Sweden. We compared two
