: Stem cell-based regeneration strategies have shown therapeutic efficacy in various fields of regenerative medicine. These include bone healing after bone augmentation, often complicated by pain, which is managed by using nonsteroidal anti-inflammatory drugs (NSAIDs). However, information is limited about how NSAIDs affect the therapeutic potential of stem cells. : We investigated the effects of ibuprofen and diclofenac on the characteristics, morphology, and immunophenotype of human mesenchymal stromal cells isolated from the dental pulp () and cultured in vitro, as well as their effects on the expression of angiogenic growth factors ( and ) and selected genes in apoptosis signalling pathways (, , , , and 2). : Ibuprofen and diclofenac significantly reduced the viability of DPSCs, while the expression of mesenchymal stem cell surface markers was unaffected. Both ibuprofen and diclofenac treatment significantly upregulated the expression of , while the expression of remained unchanged. Ibuprofen significantly altered the expression of several apoptosis-related genes, including the upregulation of and , with decreased expression. BAK, CASP3, CASP9, and BCL2 expressions were significantly increased in the diclofenac-treated DPSCs, while no difference was demonstrated in BAX expression. : Our results suggest that concomitant use of the NSAIDs ibuprofen or diclofenac with stem cell therapy may negatively impact cell viability and alter the expression of apoptosis-related genes, affecting the efficacy of stem cell therapy.

Importance: Gestational exposure to nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk of adverse fetal kidney outcomes. However, details regarding timing, specific NSAIDs, and long-term childhood kidney outcomes are limited.
Objective: To evaluate the association between gestational exposure to NSAIDs and the risk of chronic kidney disease (CKD) in childhood.
Magnetic polyoxometalate composite stabilized on the woven cotton yarn as a sorbent for thin film microextraction of some selected nonsteroidal anti-inflammatory drugs followed by high-performance liquid chromatography-ultraviolet detection.

A new thin film was fabricated using FeO@SiO-polyoxometalate (POM) as the coating and it was coupled with a HPLC-UV to develop a method for the selective determination of ibuprofen, paracetamol and diclofenac (as the model analytes) from human plasma and urine samples. The prepared magnetic POM was coated on the pores and surface of cotton yarn to prepare the extracting device. The prepared sorbent was characterized by several techniques including: FT-IR, XRD, BET, SEM, and VSM analysis.

This study investigates the removal of ibuprofen and diclofenac from aqueous media via a fully pressurized dissolved air flotation system, enhanced by fenugreek-derived saponin, a plant-based biosurfactant. The use of fenugreek saponin in flotation processes distinguishes this work from previous studies as it offers an ecofriendly and efficient alternative to chemical surfactants. The biosurfactant's surface-active properties were confirmed through FT-IR, UV-vis spectroscopy identified key functional groups and structural characteristics of the saponin, NMR provided molecular insights into its bioactive components, and surface tension analyses demonstrated its ability to reduce interfacial tension, indicating effective surfactant behavior.

Introduction: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used for pain disorders and exert pharmacological effects by inhibiting cyclooxygenase (COX). Although previous studies have evaluated the COX inhibitory activity and selectivity of NSAIDs, none has compared COX inhibitory concentrations with the plasma concentrations of clinical doses or investigated the efficacy and adverse effects of different dosage forms. Therefore, in this study we evaluated the COX inhibitory activities and inhibition rates of clinical doses of the various NSAID formulations, especially diclofenac sodium.
