ABSTRACT
The aim of this study was to evaluate the effect of Citrus sinensis essential oil (EO) on the proximate composition of yogurt over a 28-day shelf life and to investigate the therapeutic and prophylactic effects of functional yogurt on ibuprofen-induced gastric ulcers in a rat model. It was observed that the yogurt group containing C. sinensis EO had higher acidity, total solids, and ash values. Histologic evaluation of the stomachs of rats with gastric ulcers revealed that rats fed with functional yogurt had fewer lesions compared to the control group. The treatment group had fewer lesions than the positive control (p > 0.05). Lesions in the glandular mucosa of the prophylactic group were significantly lower than those in the positive control group (p < 0.05). Yogurt with C. sinensis EO may be beneficial in reducing the severity of ulcers and improving overall health.

BACKGROUND: Pain is the most prevalent complication after dentoalveolar surgery. Failure in effective pain control could potentially lead to systemic sequels, such as tachycardia, hypertension, improper nutrition, and central sensitization. Pregabalin is a gamma-aminobutyric acid (GABA) analog with inhibitory and analgesic effects on the central nervous system (CNS). Prescribing gabapentinoids as complementary analgesics reduces the consumption of opioid and non-opioid analgesics, and consequently their side effects. OBJECTIVES: The main purpose of the present study was to compare the analgesic effects of pregabalin (single-dose 75 mg) vs. ibuprofen (single-dose 400 mg) on patients' pain levels after impacted third mandibular molar surgery. MATERIAL AND METHODS: In this randomized, double-blind, split-mouth clinical trial, 24 patients aged 19-34 years volunteered for 2 consecutive (1 month apart) third mandibular molar surgeries (the contralateral teeth). The patients were randomly placed into 2 groups: group G1 (n = 12) was prescribed pregabalin (single-dose 75 mg) after the 1st surgery and ibuprofen (single-dose 400 mg) after the 2nd surgery; and group G2 (n = 12) was prescribed the exact opposite of the G1 arrangement. During the first 24 h post-surgery, the patients recorded the number of complementary analgesics they took (single-dose 400 mg ibuprofen) and their level of pain on a visual analog scale (VAS) every 2 h. RESULTS: The average level of pain at 2 h post-surgery (T1) was significantly lower when pregabalin was prescribed (p < 0.05). Most patients needed complementary analgesics at 4 h post-surgery (T2). However, during the first 24 h post-surgery, the patients required significantly more complementary analgesics when ibuprofen was prescribed. CONCLUSIONS: In comparison with oral ibuprofen (single-dose 400 mg), oral pregabalin (single-dose 75 mg) had a stronger analgesic effect at 2 h after impacted third mandibular molar surgery (p < 0.05). Pregabalin resulted in a significantly lower consumption of complementary analgesics in the first 24 h post-surgery as compared to ibuprofen.

Current study reports the combined technique of microneedle array patches and thermoresponsive gels. Microneedles array patch mediated insitu skin depots were evaluated for sustain drug delivery using sodium alginate/Poly (vinylcaprolactam) thermoresponsive gels. Their phase transition property from sol-gel state was monitored with AR2000 rheometer. Ibuprofen sodium was loaded in optimized formulations. The non-soluble cross-linked microneedle array patches (MAPs) were prepared from variable biocompatible polymers using silicone micromoulds. The fabricated MAPs were evaluated for mechanical stability, inskin dissolution, insertion forces and moisture contents. The penetration depth of MAPs in neonatal rabbit skin was tracked by optical coherence tomography. The optimized MAPs (GP10000) were used as microporation source in skin owing to their stable nature. Pores formation in skin samples after MAPs treatment was confirmed by optical coherence tomography, dye binding and skin integrity analysis. The invitro permeation of Ibuprofen sodium from formulations was studied using Franz cells across intact skin and MAPs applied skin. It was concluded from the results that Ibuprofen sodium permeation was observed for longer time through MAPs treated skin as compared to intact skin. Confocal study confirmed the diffusion of drug loaded formulations in deeper tissues with higher intensity.

BACKGROUND AND OBJECTIVE: Ibuprofen, a common non-steroidal anti-inflammatory drug, is used clinically for pain relief and antipyretic treatment worldwide. However, regular or long-term use of ibuprofen may lead to a series of adverse reactions, including gastrointestinal bleeding, hypertension and kidney injury. Previous studies have shown that CYP2C9 gene polymorphism plays an important role in the elimination of various drugs, which leads to the variation in drug efficacy. This study aimed to evaluate the effect of 38 CYP2C9 genotypes on ibuprofen metabolism. METHODS: Thirty-eight recombinant human CYP2C9 microsomal enzymes were obtained using a frugiperda 21 insect expression system according to a previously described method. Assessment of the catalytic function of these variants was completed via a mature incubation system: 5 pmol CYP2C9*1 and 38 CYP2C9 variants recombinant human microsomes, 5 µL cytochrome B5, ibuprofen (5-1000 µM), and Tris-HCl buffer (pH 7.4). The ibuprofen metabolite contents were determined using HPLC analysis. HPLC analysis included a UV detector, Plus-C18 column, and mobile phase [50% acetonitrile and 50% water (containing 0.05% trifluoroacetic acid)]. The kinetic parameters of the CYP2C9 genotypes were obtained by Michaelis-Menten curve fitting. RESULTS: The intrinsic clearance (CLint) of eight variants was not significantly different from CYP2C9*1; four CYP2C9 variants (CYP2C9*38, *44, *53 and *59) showed significantly higher CLint (increase by 35%-230%) than that of the wild-type; the remaining twenty-six variants exhibited significantly reduced CLint (reduced by 30%-99%) compared to that of the wild-type. CONCLUSION: This is the first systematic evaluation of the catalytic characteristics of 38 CYP2C9 genotypes involved ibuprofen metabolism. Our results provide a corresponding supplement to studies on CYP2C9 gene polymorphisms and kinetic characteristics of different variants. We need to focus on poor metabolizers (PMs) with severely abnormal metabolic functions, because they are more susceptible to drug exposure.

Pharmaceuticals in water are a growing environmental concern, as they can harm aquatic life and human health. To address this issue, an adsorbent made from coffee waste that effectively removes ibuprofen (a common pharmaceutical pollutant) from wastewater was developed. The experimental adsorption phase was planned using a Design of Experiments approach with Box-Behnken strategy. The relation between the ibuprofen removal efficiency and various independent variables, including adsorbent weight (0.01-0.1 g) and pH (3-9), was evaluated via a regression model with 3-level and 4-factors using the Response surface methodology (RSM) . The optimal ibuprofen removal was achieved after 15 min using 0.1 g adsorbent at 32.4 °C and pH = 6.9. Moreover, the process was optimized using two powerful bio-inspired metaheuristics (Bacterial Foraging Optimization and Virus Optimization Algorithm). The adsorption kinetics, equilibrium, and thermodynamics of ibuprofen onto waste coffee-derived activated carbon were modeled at the identified optimal conditions. The Langmuir and Freundlich adsorption isotherms were implemented to investigate adsorption equilibrium, and thermodynamic parameters were also calculated. According to the Langmuir isotherm model, the adsorbent's maximum adsorption capacity was 350.00 mg g-1 at 35 °C. The findings revealed that the ibuprofen adsorption was well-matched with the Freundlich isotherm model, indicating multilayer adsorption on heterogeneous sites. The computed positive enthalpy value showed the endothermic nature of ibuprofen adsorption at the adsorbate interface.

INTRODUCTION: Extraction of impacted molar teeth is a common procedure performed by oral surgeons and general dentists, with postoperative pain being a significant adverse event post-surgery. If mismanaged, pain can lead to complications that impact oral and systemic health. The current scourge of the opioid epidemic has ushered in a new era of provider-directed analgesic (PDA) therapy in dentistry. AREAS COVERED: This article provides an in-depth review on the major pharmacological and therapeutic properties of established and alternative analgesics used to manage dental pain. EXPERT OPINION: Substantial evidence-based literature shows a combination of a non-steroidal anti-inflammatory drug (NSAID; e.g. ibuprofen) and acetaminophen provides superior pain relief than single-agent or combination opioid regimens. However, there are clinical scenarios (e.g. severe pain) where a short-course opioid prescription is appropriate in select patients, for which a 2-3-day treatment duration is typically sufficient. Alternative agents (e.g. caffeine, gabapentin, phytotherapies), typically in combination with established agents, can mitigate postoperative dental pain. Some evidence suggests preemptive therapies (e.g. corticosteroids, NSAIDs) reduce amounts of postsurgical analgesic consumption and might lessen opioid prescription burden. In summary, this comprehensive review provides an opportune update on the evolving landscape of pharmacotherapy for acute postsurgical dental pain, informing best practices for PDA in the dental setting.

BACKGROUND: The use of NSAIDs have caused stomach injury by inhibiting endogenous mucosal prostaglandin production. Cucumis melo is reported to possess antiulcer potential. This study investigates the mechanism underlying the antiulcer potentials of Cucumis melo (CUM). METHODS: Thirty-five male Wistar rat were randomly assigned to each of seven groups; A(control given water and rat pellets), B(gastric ulcer induced with ibuprofen 400 mg/kg), C (Misoprotol 200 µg/kg), D to G (pretreated with different variation of CUM extract; 25 %, 50 %, 75 % and 100 % at a dose of 1 ml/kg for 3 weeks prior to gastric ulcer induction). Ulcer score, ulcer index and percentage inhibition, total gastric acidity was measured. Antioxidant activities, Malondialdehyde, H+/K+ ATPase, PGE2, TNF-α was done by spectrophotometry. Molecular docking investigation of Cucumis melo compounds against Prostaglandin E2 was carried out. Level of significance was tested at P ≤ 0.05 using Tukey post hoc. RESULT: Total gastric acidity, ulcer score, ulcer index, MDA, TNF-α significantly decreased after CUM treatment when compared to group B. The percentage inhibition, antioxidant activities, PGE2 concentration was significantly increased in all treatment groups compared to group B. Interactions of selected compounds of CUM with Prostaglandin E2 at various docking pockets showed folic acid has highest binding affinity followed by delta7-avenasterol and codisterol to PGE2 receptor. this study shows that one of the mechanisms by which CUM exhibits its antiulcer potential by enhancing Prostaglandin synthesis and antioxidant capacity. Therefore, Cucumis melo can therefore be explored as novel antiulcer agents.

PURPOSE: The effect of ibuprofen, an NSAID, on biological characteristics such as proliferation, viability, DNA damage and cell cycle in dental pulp derived stem cells (DPSCs) can be important for regenerative medicine. Our aim is to investigate how low and high doses of ibuprofen affect stem cell characteristics in DPSCs. MATERIALS AND METHODS: DPSCs were isolated from human teeth and characterized by flow cytometry and differentiation tests. Low dose (0.1 mmol/L) and high dose (3 mmol/L) ibuprofen were administered to DPSCs. Surface markers between groups were analyzed by immunofluorescence staining. Membrane depolarization, DNA damage, viability and cell cycle analysis were performed between groups using biological activity test kits. Cellular proliferation was measured by the MTT and cell count kit. Statistical analyzes were performed using GraphPad Prism software. RESULTS: High dose ibuprofen significantly increased CD44 and CD73 expression in DPSCs. High-dose ibuprofen significantly reduced mitochondrial membrane depolarization in DPSCs. It was determined that DNA damage in DPSCs decreased significantly with high dose ibuprofen. Parallel to this, cell viability increased significantly in the ibuprofen applied groups. High-dose ibuprofen was found to increase mitotic activity in DPSCs. Proliferation in DPSCs increased in parallel with the increase in mitosis stage because of high-dose ibuprofen administration compared to the control and low-dose ibuprofen groups. Our proliferation findings appeared to support cell cycle analyses. CONCLUSION: High dose ibuprofen improved the immunophenotypes and biological activities of DPSCs. The combination of ibuprofen in the use of DPSCs in regenerative medicine can make stem cell therapy more effective.

PURPOSE: To evaluate time-dependent administration of ibuprofen in a lower third molar extraction model. METHODS: Eleven patients requiring bilateral surgical removal of lower third molars were recruited and randomized into a blinded crossover randomized controlled trial. For 3 days after surgery, the control group was prescribed ibuprofen 400 mg every 8 h. On the other hand, the experimental group received also ibuprofen 400 mg at breakfast and lunch, replacing the dinner intake with a placebo. Pain measurements (Visual Analog Scale from 0 to 10) were recorded at baseline, 24, 48, and 72 h postoperatively. Facial swelling and trismus were also measured at baseline, 24, and 72 h postoperatively. RESULTS: Postoperative swelling and pain perception did not show significative difference between the control and experimental groups at 24, 48, and 72 h. Trismus was significantly lower in the control group than in the experimental group at 72 h postoperatively (p = 0.008). Rescue medication consumption seemed to be comparable between groups. CONCLUSION: Eliminating night time ibuprofen might be insignificant for pain control after third molar extraction.

Vulvar squamous cell carcinoma (VSCC) is a rare malignancy with a relatively good prognosis. However, the prognosis remains poor for elderly patients and those with a significant depth of tumor invasion; thus, novel treatment modalities are needed. The aim of this study was to analyze the impact of cannabidiol (CBD) and its combination with NSAIDs, diclofenac (DIC) and ibuprofen (IBU) on VSCC cells. In this regard, the MTT test was applied for cytotoxicity analysis. Moreover, the influence of CBD, DIC and IBU, as well as their combinations, on apoptosis and cell cycle distribution were analyzed by flow cytometry. The mechanisms of action of the analyzed compounds, including their impact on NF-κB signaling, p53 and COX-2 expression were evaluated using Western blot. This study shows that CBD and its combinations with NSAIDs are cytotoxic to A431 cells, but they also reduce, in a dose-dependent manner, the viability of immortalized keratinocyte HaCaT cells, and human umbilical vein cell line, EA.hy926. Moreover, the compounds and their combinations induced apoptosis, diminished the NF-κB signaling activation and reduced COX-2 expression. We conclude that CBD and its combination with DIC or IBU are promising candidates for the adjuvant treatment of high-risk VSCC patients. However, their impact on non-cancerous cells requires careful evaluation.

BACKGROUND: Mucilage and pectin are both natural polymers with the advantages of availability and biodegradability. Microspheres made from biodegradable polymers can break down naturally after performing their tasks. OBJECTIVES: The study aimed to use mucilage and pectin from the leaves of Talinum triangulare (Jacq.) Willd. as polymer matrices for the formulation of microspheres, with ibuprofen as the model drug. MATERIAL AND METHODS: Both polymers were examined under a microscope and evaluated using measurements of viscosity, density, flow properties, swelling power, elemental analysis, Fourier-transform infrared spectroscopy (FTIR), and the degree of esterification (DE) for pectin. The microspheres were prepared using the ionotropic gelation method and alginate:mucilage/pectin at ratios of 1:1 and 1:2. They were assessed for swellability, drug entrapment effectiveness and drug release profile. RESULTS: The mucilage particles were ovoid while pectin particles were irregularly shaped. Pectin had higher particle, bulk and tapped densities than mucilage, while mucilage had a higher swelling power and a better flow than pectin. Talinum triangulare pectin is a low-methoxyl pectin with a DE of 7.14%. The FTIR spectra showed no interaction between the polymers and ibuprofen. The surface morphology of the microspheres without ibuprofen was smooth, while those with ibuprofen revealed a spongy-like mesh. The swelling power of the microspheres was higher in phosphate buffer with a pH of 7.2 than in distilled water. The entrapment efficiency ranged within 39.57-60.43% w/w, with microspheres containing alginate:mucilage/pectin ratio of 1:1 having higher entrapment efficiency. Microspheres with polymer at a ratio of 1:1 provided a longer release (>2 h), while microspheres with polymer blend of 1:2 provided an immediate release of ibuprofen. CONCLUSIONS: The polymers of T. triangulare could be used as matrices in microsphere formulations.

Many studies have indicated that the risk of cognitive impairment is higher in patients with rheumatoid arthritis (RA). Additionally, patients with RA may have a lower incidence of cognitive impairment with long-term use of ibuprofen. This study was aimed at investigating the impacts of RA on memory function and the mechanisms that ibuprofen may exhibit to improve memory function in rats with collagen-induced arthritis (CIA). Ibuprofen (30 mg/kg) was given twice daily to CIA rats for two weeks starting from Day 18 following the first immunization. Memory function was measured by the Morris water maze (MWM) test and long-term potentiation (LTP). The proinflammatory cytokine levels and downstream signaling pathways, including mitogen-activated protein kinase (MAPK) and nuclear factor kappa B (NF-κB), were examined. Furthermore, the glutamatergic system, including glutamate transporters/receptors and brain extracellular levels of glutamate, was investigated. The results showed that the impaired learning memory in CIA rats, examined by the MWM test and LTP, can be ameliorated by ibuprofen treatment. Along with the improvement in memory deficits, ibuprofen attenuated both neuroinflammation and the associated elevated levels of phosphorylated p38, JNK, and p65 in the hippocampus of CIA rats. In addition, the decreased excitatory amino acid transporter 2 level, the increased extracellular glutamate, and the upregulated hippocampal NMDA receptor 2B of CIA rats were all normalized by ibuprofen treatment. These findings suggest that the effect of ibuprofen on the memory improvement in CIA rats is associated with the normalization of the activated MAPK and NF-κB pathways and the aberrant glutamatergic system.

Aim: To compare the homeopathic drug Arnica with ibuprofen as an analgesic for postextraction pain control in children. Materials and methods: Forty-four healthy children between 8 and 12 years of age requiring two clinical sessions of tooth extraction in two different quadrants of the oral cavity were selected for the study. All the children received both the drugs in this crossover trial with a washout of 10 days. Patient-rated and operator-assessed pain was compared to a 10-point validated Visual Analog Scale at baseline, 24, 48, and 72 hours using the paired t-test. Acceptance to taste and frequency of dosing was recorded at the end of three days using a five-point Likert scale and were compared using the Chi-squared test. Kappa statistics were performed to assess intraoperator variability. Results: Pain reduction by Ibuprofen was significantly more than Arnica only at 48 hours with respect to both patient-reported and operator-assessed pain [(t = 3.567, p < 0.05), (t = 2.834, p < 0.05)]. As the age of the child increased, patient-reported pain significantly decreased. Children preferred the taste of Arnica over that of Ibuprofen (x 2 = 56.76, p < 0.0001). Conclusion: There was no difference between Arnica and Ibuprofen in the postextraction pain management in 8-12-year-old children. Clinical significance: The results of this study suggest that Arnica may be considered as an alternative to ibuprofen in managing postextraction pain in 8-12-year-old children, especially those with asthma, COPD, or known allergy to ibuprofen.

ABSTRACT
Backgrounds: Drugs with the ability to displace bilirubin from albumin-binding sites subsequently leading to an increased bilirubin level may cause hyperbilirubinemia in neonates. Ibuprofen is commonly used to treat patent ductus arteriosus (PDA) in neonates, yet the use of ibuprofen has drawn mixed conclusions. We performed a retrospective study to determine how ibuprofen use influences the total serum bilirubin (TSB) level in neonates of differing birth weight (BW). Materials and methods: Neonates (including premature infants) born at Chang Gung Memorial Hospital, Taiwan during January 2004 to July 2020 were entered into this study. We recorded the phototherapy duration, including the initial day and end day, and determined the average influence of one-day phototherapy on TSB level. The highest monitored TSB level post-ibuprofen use minus the one measured prior to ibuprofen use was considered the TSB change following ibuprofen administration in this study, and the above-mentioned influence of daily phototherapy on the TSB level was used to correlate the results. Neonates with any of the following conditions were excluded: those who received ceftriaxone, those with intraventricular hemorrhage, and those infected with TORCH. Results: The average daily influence of phototherapy on the TSB level of neonates was −0.20 (−0.57~0.05) mg/dL, −0.28 (−0.84~0.13) mg/dL, −0.75 (−1.77~0.10) mg/dL, and −1.60 (−2.70~−0.50) mg/dL in neonates with BWs of <1 kg, 1−1.49 kg, 1.5−2.49 kg, and ≥2.5 kg, respectively, indicating that neonates with a BW ≥ 1.5 kg experienced a greater reduction in TSB level following phototherapy as compared with those with a BW < 1.5 kg. The average TSB increase following ibuprofen use in neonates was 3.38 ± 2.77 mg/dL, 2.04 ± 2.53 mg/dL, and 1.34 ± 2.24 mg/dL in neonates with BWs of <1 kg, 1−1.49 kg, and ≥1.5 kg, respectively, i.e., an elevated TSB change with a decreased neonate BW was noted post-ibuprofen use (p = 0.026, one-way analysis of variance (ANOVA)). Conclusions: As ibuprofen use is correlated with an apparent increase in TSB level in neonates with a lower BW, especially in those with a BW < 1 kg, iv acetaminophen can be an appropriate alternative to ibuprofen for ELBW neonates for the treatment of PDA if they are experiencing severe unconjugated hyperbilirubinemia.
ABSTRACT
Ibuprofen is a nonsteroidal anti-inflammatory drug that is commonly used for its analgesic, antipyretic and anti-inflammatory effects worldwide. However ibuprofen comes with serious unavoidable adverse effects on various organs when used for long duration or overdosed. Trichopus zeylanicus is a medicinal plant endemic to India owning various beneficial properties and is been used in treating various ailments. Therefore, the objective of this study was to evaluate the ameliorative effect of aqueous leaves' extract of Trichopus zeylanicus against ibuprofen-induced hepatic toxicity and enteropathy in rats. Overall in this study 30 male albino rats were used, which were divided into five groups (six in each group). Group-I was normal control, Group-II was ibuprofen (400 mg/kg/day) inebriated group, Group-III was silymarin (25 mg/kg/day) pretreated + ibuprofen (400 mg/kg/day), Group-IV was ALETZ (1000 mg/kg/day) pretreated + ibuprofen (400 mg/kg/day), and Group-V was ALETZ alone (1000 mg/kg/day) group. The duration of the administration was for five days, followed by scarifying rats on the sixth day. Later the rats were assessed for liver and intestine enzyme markers, antioxidant parameters along with histopathological changes. In addition the pro-inflammatory markers such as TNF-α, IL-6 and IL-1ß as well as anti-inflammatory cytokine IL-10 levels were measured using ELISA. Lastly the expression pattern of apoptotic signaling markers such as caspase-3, caspase-8 and Bcl-2 was evaluated using western blot. The results obtained from this study showed changes in levels of aforesaid parameter which presented the toxic effect of ibuprofen on liver and small intestine. Pre-treatment of ALETZ in ibuprofen-inebriated group was able to normalize the adverse effect caused due to ibuprofen. The conclusion of the study deduces that pre-treatment with ALETZ alleviates by modulating oxidative stress, inflammation, and apoptosis in ibuprofen inebriated rats, indicating its protective mechanism.

BACKGROUND: Micropollutants comprise organic/mineral substances that cause an undesirable impact on the environment, by affecting life at all scales. In this study, we explored the changes they impart on the global proteome of a soil bacterium Serratia nematodiphila MB307, for two classes of pollutants, i.e., Azo dyes (Methyl orange, Congo red) and a pharmaceutical (Ibuprofen). METHODS: The 100 µg pollutant supplemented alteration of pure S. nematodiphila MB307 culture after 24 hours of incubation at 37 °C and its control was analyzed using a differential proteomics approach. MaxQuant software with the Perseus package was used for data analysis purposes. RESULTS: Prominently, ribosomal proteins and chaperones were up or downregulated in the whole cell and membranous fraction. CONCLUSION: This illustrates dynamic protein production adaptation of bacteria, to cope with stress and cell growth/division trade-off for survival. A collective pattern of survival under stress or pollution resistance could not be decrypted for all classes of pollutants, portraying dissimilar mechanisms of coping with differently structured pollutant moieties.

From the metagenome of a carbamazepine amended selective enrichment culture the genome of a new to science bacterial species affiliating with the genus Nocardioides was reconstructed. From the same enrichment an aerobic actinobacterium, strain CBZ_1T, sharing 99.4% whole-genome sequence similarity with the reconstructed Nocardioides sp. bin genome was isolated. On the basis of 16S rRNA gene sequence similarity the novel isolate affiliated to the genus Nocardioides, with the closest relatives Nocardioides kongjuensis DSM19082T (98.4%), Nocardioides daeguensis JCM17460T (98.4%) and Nocardioides nitrophenolicus DSM15529T (98.2%). Using a polyphasic approach it was confirmed that the isolate CBZ_1T represents a new phyletic lineage within the genus Nocardioides. According to metagenomic, metatranscriptomic studies and metabolic analyses strain CZB_1T was abundant in both carbamazepine and ibuprofen enrichments, and harbors biodegradative genes involved in the biodegradation of pharmaceutical compounds. Biodegradation studies supported that the new species was capable of ibuprofen biodegradation. After 7 weeks of incubation, in mineral salts solution supplemented with glucose (3 g l-1) as co-substrate, 70% of ibuprofen was eliminated by strain CBZ_1T at an initial conc. of 1.5 mg l-1. The phylogenetic, phenotypic and chemotaxonomic data supported the classification of strain CBZ_1T to the genus Nocardioides, for which the name Nocardioides carbamazepini sp. nov. (CBZ_1T = NCAIM B.0.2663 = LMG 32395) is proposed. To the best of our knowledge, this is the first study that reports simultaneous genome reconstruction of a new to science bacterial species using metagenome binning and at the same time the isolation of the same novel bacterial species.

Direct back-face transmission steady-state fluorescence was successfully applied to the study of aggregation of ibuprofen and ibuprofenate anion in solution taking advantage of its own fluorescence. The analysis of the experimental data involves the use of the differential reabsorption model to account for re-absorption phenomenon and the closed association model to describe aggregation. The fluorescence quantum yield of ibuprofenate increases when it aggregates in the presence of sodium, but it markedly decreases when 1-butyl-3-methylimidazolium is used as counterion. The proposed methodology allows the accurate determination of the critical aggregation concentrations and the mean aggregation numbers. Results were supported by complementary techniques such as time-resolved fluorescence, 1H-NMR and small-angle neutron and X-ray scattering. The developed technique constitutes a promising strategy to characterize the aggregation of poorly fluorescent surfactants that aggregates at high concentrations and hence at high absorbance values, conditions in which the most common right-angle configuration for fluorescence acquisition is troublesome due to re-absorption.

Ibuprofen (IBU) and naproxen (NPX) are commonly used non-steroidal anti-inflammatory drugs (NSAIDs) with high-risk quotients and are frequently detected in various aquatic environments. A weak electrostimulated biofilm not only had improved removal efficiencies to IBU and NPX, but also transformed different enantiomers with comparable efficiency and without configuration inversion. IBU was transformed mainly by oxidation (hydroxyl-IBU, carboxy-IBU), while NPX was mainly detoxified. The microbial analysis of IBU and NPX biofilm showed that the shared core consortia (> 1%) contained typical electro-active bacteria (Geobacter, Desulfovibrio), fermenters (Petrimonas, Acetobacterium) and potential degraders (Pandoraea, Nocardiaceae), which exhibited synergistic interactions by exchanging the additional electrons, H+, coenzyme NAD(H) or NAD(P) (H) and energy. The fungal community has a significant correlation to those core bacteria and they may also play transformation roles with their diverse enzymes. Plenty of nonspecific oxidoreductase, decarboxylase, hydrolase, cytochrome P450, and other enzymes relating to xenobiotic degradation were high-abundance encoded by the core consortia and could potentially participate in IBU and NPX biotransformation. This study offers new insights into the functional microbes and enzymes working on complex NSAIDs biotransformation and provided a feasible strategy for the enhanced removal of NSAIDs (especially IBU and NPX).

OBJECTIVE: To examine the effects of ibuprofen, naproxen and diclofenac, non-steroidal anti-inflammatory drugs (NSAIDs) on cell proliferation activity of the human CCA cell lines. METHODS: KKU-M139 and KKU-213B cell lines were used in this study. The cell viability was assessed by the MTT assay. Lipid synthesis determined by Oil red O staining and colorimetric assay. An inverted phase-contrast light microscope was used to investigate the histological change of the cells. Caspases 3/7 activity and AnnexinV/PI were used to assess apoptosis by multiple microplate reader. RESULTS: The results showed that ibuprofen, naproxen and diclofenac suppressed the viability of the KKU-M139 and KKU-213B cells in a dose-dependent manner, as measured especially diclofenac. However, these three NSAIDs slightly decreased lipid synthesis determined by Oil red O staining and colorimetric assay. The histological change observations showed the shrinking cell and become star-shaped in high dose treated groups. Interestingly, these NSAIDs exhibited in both of KKU-M139 and KKU-213B cell lines, the diclofenac-treated cells had the most injury cells. The cells exhibited cell injury features. In addition, the detection of caspase 3/7 and AnnexinV/PI in this investigation revealed early cell apoptotic characteristics. CONCLUSION: These finding suggest that ibuprofen, naproxen and diclofenac suppress cell viability. The results reveal that ibuprofen, naproxen and diclofenac, which induce the histological change and apoptosis. This study indicates that these NSAIDs may be used as an anti-proliferation agent for the treatment of CCA in the future.
