AB  - Thyroid hormones (TH) have a significant impact on cellular oxidative metabolism. Besides that,they maintain vascular homeostasis by positive effects on endothelial and vascular smooth muscle cells. Subclinical(SCH) and clinical (CH) hypothyroidism influences target organs by changing their morphology andfunction and impaired blood and oxygen supply induced by accelerated atherosclerosis. The increased risk ofacceleration and extension of atherosclerosis in patients with SCH and CH could be explained by dyslipidemia,diastolic hypertension, increased arterial stiffness, endothelial dysfunction, and altered blood coagulation. Instabilityof atherosclerotic plaque in hypothyroidism could cause excessive activity of the elements of innateimmunity, which are characterized by the significant presence of macrophages in atherosclerotic plaques, increasednuclear factor kappa B (NFkB) expression, and elevated levels of tumor necrosis factor α (TNF-α) andmatrix metalloproteinase (MMP) 9, with reduced interstitial collagen; all of them together creates inflammationmilieu, resulting in plaque rupture. Optimal substitution by levothyroxine (LT4) restores biochemical euthyroidism.In postmenopausal women and elderly patients with hypothyroidism and associated vascularcomorbidity, excessive LT4 substitution could lead to atrial rhythm disorders and osteoporosis. Therefore, it isof interest to maintain thyroid-stimulating hormone (TSH) levels in the reference range, thus eliminating thedeleterious effects of lower or higher TSH levels on the cardiovascular system. This review summarizes the recentliterature on subclinical and clinical hypothyroidism and atherosclerotic cardiovascular disease and discussesthe effects of LT4 replacement therapy on restoring biochemical euthyroidism and atherosclerosis processes.

AB  - Nickel acetate tetrahydrate (NAT) sample series were used to modify screen-printed carbon electrodes (SPCE). The samples were hybrid Ni/NiO nanocomposites, where the NiO phase increased with an applied treatment temperature. Results of electrochemical measurements pointed that the Ni/NiO550/SPCE-modified electrode had the best analytical performance toward the detection of riboflavin (RF). The Ni/NiO550/SPCE-based sensor showed linear response with RF in the concentration range of 0.5–75 μM and 0.15 μM LOD in BRBS. Sensor offered fast response time, good repeatability, and selectivity with an RSD of 1.4 %. Our results show that the Ni:NiO nanocomposite ratio strongly influenced the electroanalytical performance of SPCE.

AB  - Background Myocardial infarction (MI) leads to ischemia and afterward to left ventricular (LV) remodeling. Matrix metalloproteinase−1 (MMP1) and −3 (MMP3) belong to the family of endopeptidases and together they can dissolve most of the components of the extracellular matrix. MMP1 and MMP3 variants have been investigated solely in association with ischemic heart disease and LV dysfunction, but not in haplotype. The aims of this study were to investigate the association of haplotypes inferred from MMP1 rs1799750 (−1607 1G/2G; NC_000011.9:g.102670497del) and MMP3 rs35068180 (−1612 5A/6A; NC_000011.9:g.102715952dup) with MI and their effect on the change in echocardiographic parameters of LV structure and function in patients within 6 months after MI. Methods The study included 325 patients with the first MI and 283 healthy controls. Gene variants were detected by PCR-RFLP method. Parameters of LV structure and function were assessed by conventional 2D echocardiography, 3–5 days and 6 months after the first MI, on a subgroup of 160 patients. Haplotype analysis was performed with Thesias software. Results Haplotypes 2G-5A and 1G-6A were significantly and independently associated with MI compared with the reference haplotype 2G-6A (adjusted, p = 0.009 and p = 0.026, respectively). After Bonferroni correction for multiple testing, MMP1 and MMP3 haplotypes lost their association with the change in LV long diameter and stroke volume within 6 months after MI. Conclusion MMP1 and MMP3 haplotypes are strongly associated with MI. Further studies are needed to validate this result and to examine their association with echocardiographic parameters of LV structure and function after MI.

AB  - Aluminum nitride (AlN) and boron nitride (BN) are well-known ceramic materials with numerous valuable properties, whereas recently there is a growing field of research on the AlN/BN advanced ceramic materials. Here, we present a study on boron-rich AlN, structural and electronic properties, and structure–property relationship. Several AlxB1−xN solid solutions (x = 1, .875, .75, and .625) have been investigated, and structure optimization has been performed for four different structure types: h-BN, wurtzite, sphalerite, and rock salt. First-principles calculations were performed using hybrid B3LYP functional. New modifications and compounds have been predicted as a function of boron concentration in AlN, and especially, interesting phase transitions were found at extreme pressure conditions. Electronic properties and band structures were computed, and the possibility for bandgap tuning has been discovered. The present study, and especially the structure–property relationship, gives new possibilities for bandgap engineering in boron-rich AlN electroceramic materials.

AB  - The operating characteristics of a commercial monocrystalline and amorphous Si-solar cell for outdoor and indoor applications with and without the use of the water flow lens (WFL) system are explored and reported. The cells are tested in indoor conditions with halogen and tungsten lamps, and additionally, in outdoor sun radiation. Changes in the spectra, investigation of the influence of higher and lower lighting, and indirect cooling of the solar cell are possibilities in the application of the used WFL system. After achieving the highest level of development and improvement for the Si-solar cell, as well as approaching theoretical maximum efficiency, it is obvious that efficiency gains can be made by better understanding additional light effects. Measurements made on monocrystalline Si-solar cells revealed that in the “focal point position” where intensity increases (above standard testing conditions [STC]), independently of indoor or outdoor lighting, huge improvements in ISC and VOC were observed. It was found that the ratios of the short-circuit current (ISC) and the input light energy (Pinput) are 5.2 and 24.8 for artificial light and 4.9 and 17.6 for outdoor light, without and with the use of the WFL system, respectively. The same trend after applying the WFL system was observed for the amorphous Si cell, except those oscillations were more pronounced at lower light intensities (far lower than STC), as expected. The ratios of ISC and Pinput are in the range of 5.1–5.3 and 10.5–26.5 without and with the use of the WFL system.

The present article focuses on the use of material supports for developing immobilized biocatalysts in applications related to energy, environment and chemical synthesis. The work provides a comprehensive overview of a broad class of materials, including organic, inorganic and composites, that have been shown to be prosperous candidates to support the immobilization of enzymes and microbial cells. It also highlights the properties of nanomaterial support such as large surface area and comfort compartment for immobilization. The availability of different types of materials as catalyst support provides an opportunity to understand and develop efficient biocatalytic systems. The choice of selecting a catalyst support will mostly depend on the interaction of the material with the enzyme or microbial cell.

AB  - In this study, four low molecular weight (LMW) excipients, tryptophan (TRY), phenylalanine (PHE), lysine (LYS) and saccharin (SAC) were evaluated as co-formers to generate co-amorphous systems (CAMS) by ball milling with carvedilol (CRV). Mixtures of CRV and LMW excipient in 1:0.5, 1:1 and 1:2 drug:excipient molar ratios were ball milled and analysed by powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), Fourier transform (FT-IR) infrared spectroscopy and dissolution testing. CAMS were formed by milling of a mixture of CRV with TRY in 1:2 M ratio and SAC in 1:1 M ratio, while amorphization of only CRV was achieved in other mixtures with SAC. In other samples containing TRY and PHE, milling resulted in partial amorphization, while LYS was the least suitable excipient for the amorphization of CRV. Unexpectedly, the highest supersaturation of CRV was achieved from samples containing CRV and LYS in 1:1 and 1:2 M ratios, despite the absence of a significant reduction in CRV crystallinity upon milling of these samples. Increase of hydrophobic surface area caused by milling of samples with TRY and PHE and agglomeration during dissolution testing of samples containing SAC are likely causes of poor dissolution performance of mixtures containing fully or partially amorphous CRV.

abstract = "In this study, four low molecular weight (LMW) excipients, tryptophan (TRY), phenylalanine (PHE), lysine (LYS) and saccharin (SAC) were evaluated as co-formers to generate co-amorphous systems (CAMS) by ball milling with carvedilol (CRV). Mixtures of CRV and LMW excipient in 1:0.5, 1:1 and 1:2 drug:excipient molar ratios were ball milled and analysed by powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), Fourier transform (FT-IR) infrared spectroscopy and dissolution testing. CAMS were formed by milling of a mixture of CRV with TRY in 1:2 M ratio and SAC in 1:1 M ratio, while amorphization of only CRV was achieved in other mixtures with SAC. In other samples containing TRY and PHE, milling resulted in partial amorphization, while LYS was the least suitable excipient for the amorphization of CRV. Unexpectedly, the highest supersaturation of CRV was achieved from samples containing CRV and LYS in 1:1 and 1:2 M ratios, despite the absence of a significant reduction in CRV crystallinity upon milling of these samples. Increase of hydrophobic surface area caused by milling of samples with TRY and PHE and agglomeration during dissolution testing of samples containing SAC are likely causes of poor dissolution performance of mixtures containing fully or partially amorphous CRV.",

AB  - As a renewable resource, starch is considered to be fully biodegradable and nonpolluting to the environment but the hygroscopicity of starch is the main disadvantage for wider applicability in the production of a polymer-based material. Hydrophobically modified starch prepared using natural-based plasticizers/modifiers in a first step ([-]-diisopropyl D-tartrate [DiPT], ricinoleic acid [RA] and epoxidized soybean oil [ESO]), and maleated polypropylene (MAPP) in a second step contributed to better compatibility, and thus reinforcing of composites. Tailored processing conditions, structural/morphological properties, hydrophobicity, and water-resistance of the modified starch were established. In addition, the Charpy impact and tensile strength of composites, based on poly(ethylene-co-acrylic acid) (EAA) and modified starches, were determined. Increased tensile strength and Young modulus of the composite using starch-modified with DiPT-MAPP, that is, 3 and 83%, respectively, indicated the possible applicability of obtained materials.

AB  - Polymer matrix composite materials have found application in dentistry because of good mechanical properties, aesthetic, easy processing, and possibilities of the repair. Acrylates are materials used to make and repair dentures. Reinforcements in the form of short glass or polymer fibers are added to improve the mechanical properties of dental polymers. In this study, the processing of composite material with a polymer matrix from commercial auto-polymerized acrylate Simgal, with reinforcement in the form of short poly(ethylene terephthalate) (PET) fibers was examined. Samples were processed in three series: pure Simgal, Simgal/PET 1 wt% and Simgal/PET 3 wt%. The influence of the reinforcement in the form of short PET fibers on the mechanical properties of composite materials was investigated. Strength and hardness were tested by impact testing and Vickers microhardness, and it was shown that there is an increase in absorbed energy and hardness. The modulus was reduced by the addition of PET fibers and by increasing the amount of fibers in the composite. The increase in the amount of PET fibers also resulted in a smaller loss of surface mass of the samples compared to the pure matrix by 63% and 93%, respectively. Cavitation test revealed better cavitation resistance of composites than the pure acrylate.

AB  - Aims GABAergic modulation involved in cognitive processing appears to be substantially changed in Alzheimer's disease (AD). In a widely used 5xFAD model of AD, we aimed to assess if negative and positive allosteric modulators of α5 GABAA receptors (NAM and PAM, respectively) would affect social interaction, social, object and spatial memory, and neuroinflammation. Methods After 10-day treatment with PAM, NAM, or solvent, 6-month-old transgenic and non-transgenic 5xFAD mice underwent testing in a behavioral battery. Gene expressions of IL-1β, IL-6, TNF-α, GFAP, and IBA-1 were determined in hippocampus and prefrontal cortex by qPCR. Results PAM treatment impaired spatial learning in transgenic females compared to solvent-treated transgenic females, and social recognition in transgenic and non-transgenic males. NAM treatment declined social interaction in transgenic and non-transgenic males, while had beneficial effect on cognitive flexibility in non-transgenic males compared to solvent-treated non-transgenic males. Transgenic animals have not fully displayed cognitive symptoms, but neuroinflammation was confirmed. NAM reduced proinflammatory gene expressions in transgenic females and astrogliosis in transgenic males compared to pathological controls. Conclusion PAM and NAM failed to exert favorable behavioral effects in transgenic animals. Suppression of neuroinflammation obtained with NAM calls for more studies with GABAergic ligands in amyloid beta- and/or tau-dependent models with prominent neuroinflammation.

AB  - Theoretical tools or structure-property relations that enable the prediction of metal hydrides are of enormous interest in developing new hydrogen storage materials. Density functional theory (DFT) is one such approach that provides accurate hydride formation energies, which, if complemented with vibrational zero-point energy and other contributions, provides accurate hydride formation enthalpies. However, this approach is time consuming and, therefore, often avoided, hindering the modeling of experimental behavior. The recent implementation of graph neural networks (GNN) in materials science enables fast prediction of crystal formation energy with a DFT accuracy. Starting from the MatErials Graph Network (MEGNet), transfer learning is applied to develop a model for predicting hydride formation enthalpy based on the crystal structure of the starting intermetallic. Excellent accuracy is achieved for Mg-containing alloys, allowing the screening of the Mg-Ni-M ternary intermetallics. In addition, data containing matching experimental properties and crystal structure of metal hydrides are provided, enabling future development.

AB  - Objectives This study aimed to experimentally validate dysregulated expression of miRNA candidates selected through updated meta-analysis of most commonly deregulated miRNAs in oral cancer and to explore their diagnostic and prognostic potential. Materials and methods Five miRNAs (miR-31-3p, miR-135b-5p, miR-18a-5p, miR-30a-5p and miR-139-5p) from updated meta-signature were selected for validation by qRT-PCR method in 35 oral cancer clinical specimens and adjacent non-cancerous tissue. Results Updated meta-analysis has identified 13 most commonly deregulated miRNAs in oral cancer. Seven miRNAs were consistently up-regulated (miR-21-5p, miR-31-3p, miR-135b-5p, miR-31-5p, miR-424-5p, miR-18a-5p and miR-21-3p), while five were down-regulated (miR-139-5p, miR-30a-3p, miR-375-3p, miR-376c-3p and miR-30a-5p). Increased expression of miR-31-3p and miR-135b-5p, and decreased expression of miR-139-5p and miR-30a-5p were confirmed in oral cancer compared to adjacent non-cancerous tissue. A three miRNAs combination (miR-31-3p, miR-139-5p and miR-30a-5p) gave the most promising diagnostic potential for discriminating oral cancer from non-cancerous tissue (AUC: 0.780 [95% CI: 0.673–0.886], p < 0.0005, sensitivity 94.3%, specificity 51.4%). High expression of miR-135b-5p, miR-18a-5p and miR-30a-5p was associated with poor survival (p = 0.003, p = 0.048, p = 0.016 respectively). Conclusion miR-31-3p, miR-139-5p and miR-30a-5p panel was confirmed as a potential diagnostic biomarker when distinguishing oral cancer from non-cancerous tissue. miR-135b-5p, miR-18a-5p and miR-30a-5p might serve as potential biomarkers of poor survival of oral cancer patients.

Currently, no effective vaccines are available for pathogens with a highly variable antigenic load, such as the human immunodeficiency virus or to induce cellular T-cell immunity in the fight against cancer. The recent SARS-CoV-2 outbreak has reinforced the relevance of designing smart therapeutic vaccine modalities to ensure public health. Indeed, academic and private companies have ongoing joint efforts to develop novel vaccine prototypes for this virus. Many pathogens are covered by a dense glycan-coat, which form an attractive target for vaccine development. Moreover, many tumor types are characterized by altered glycosylation profiles that are known as “tumor-associated carbohydrate antigens”. Unfortunately, glycans do not provoke a vigorous immune response and generally serve as T-cell-independent antigens, not eliciting protective immunoglobulin G responses nor inducing immunological memory. A close and continuous crosstalk between glycochemists and glycoimmunologists is essential for the successful development of efficient immune modulators. It is clear that this is a key point for the discovery of novel approaches, which could significantly improve our understanding of the immune system. In this review, we discuss the latest advancements in development of vaccines against glycan epitopes to gain selective immune responses and to provide an overview on the role of different immunogenic constructs in improving glycovaccine efficacy.

AB  - Objective Cholesteatoma is a challenging chronic pathology of the middle ear for which pharmacologic therapies have not been developed yet. Cholesteatoma occurrence depends on the interplay between genetic and environmental factors while master regulators orchestrating disease progression are still unknown. Therefore, in this review, we will discuss the diagnostic and therapeutic potential of non-coding RNAs (ncRNA) as a new class of regulatory molecules. Methods We have comprehensively reviewed all articles investigating ncRNAs, specifically micro RNAs (miRNAs) and long ncRNAs (lncRNA/circRNA) in cholesteatoma tissue. Results Candidate miRNA approaches indicated that miR-21 and let-7a are the major miRNAs involved in cholesteatoma growth, migration, proliferation, bone destruction, and apoptosis. Regulatory potential for the same biological processes was also observed for miR-203a. The NF-kB/miR-802/PTEN regulatory network was in relation to observed miR-21 activity in cholesteatoma as well. High throughput approaches revealed additional ncRNAs implicated in cholesteatoma pathology. Competitive endogenous RNA (ceRNA) analysis highlighted lncRNA/circRNA that could be “endogenous sponge” for miR-21 and let-7a based on the hypothesis that RNA transcripts can communicate with and regulate each other by using shared miRNA response elements. Conclusion In this review, we summarize the discoveries and role of ncRNA in major pathways in cholesteatoma and highlight the potential of miRNA-based therapeutics in the treatment of cholesteatoma.

AB  - One of the most effective ways of gaining user experience and minimizing user effects on modelling and simulation is benchmarking. Currently (2022) a new experimental workplace, the so called 'Mini Labyrinth' is being developed at Slovak University of Technology in Bratislava (STU). It is a simple neutron and gamma shielding benchmark, inspired by the ALARM-CF-AIR-LAB-001 ICSBEP experiment. The latest V2 setup consists of a PuBe neutron source, several NEUTRONSTOP C5 shielding blocks, H2O filled polylactic acid (PLA) tank, plastic source holder and detectors placed inside and outside the Mini Labyrinth. This paper is focused on the monitoring of the radiation doses around the workplace using the NuDET neutron detector and on the comparison of the measured quantities with ones simulated by SCALE 6 MONACO. The influence of the size of the model and the definition of the detector is studied in this analysis. The achieved results are presented and some discussions on further needed development are also included.

The use of nanocomposites allows application in various types of therapy or theranostics. In this work, we propose a new approach for the fabrication of a gold/ferrite nanocomposite, which consists of gold particles up to 10 nm in diameter surrounded by small nanoparticles of cobalt ferrite (~5 nm) doped with zinc. The gold core is coated with arginine, while the ferrite particles have dihydrocaffeic acid shell. The fabricated nanocomposite possesses optical and magnetic properties due to the excitation of localized plasmon resonance in gold particles and the superparamagnetic state of ferrite particles. The results of studying the structural, magnetic, and optical properties, as well as the cytotoxicity of the obtained nanocomposite, allow us to conclude that it can be used in combined photo- and magnetic hyperthermic therapy.

AB  - In this work, Ag-doped ZnO nanoparticles are obtained via pulsed laser ablation of the Ag-coated ZnO target in water. The ratio of Ag dopant in ZnO nanoparticles strongly depends on the thickness of the Ag layer at the ZnO target. Synthesized nanoparticles were characterized by XRD, XPS, SEM, EDS, ICP-OES, and UV–VIS spectrophotometry to obtain their crystal structure, elemental composition, morphology and size distribution, mass concentration, and optical properties, respectively. The photocatalytic studies showed photodegradation of methylene blue (MB) under UV irradiation. Different ratios of Ag dopant in ZnO nanoparticles influence the photodegradation rate. The ZnO nanoparticles doped with 0.32% silver show the most efficient photodegradation rate, with the chemical reaction constant of 0.0233 min−1. It exhibits an almost twice as large photodegradation rate compared to pure ZnO nanoparticles, showing the doping effect on the photocatalytic activity.

AB  - Structural modification of different carbon-based nanomaterials is often necessary toimprove their morphology and optical properties, particularly the incorporation of N-atoms ingraphene quantum dots (GQDs). Here, a clean, simple, one-step, and eco-friendly method forN-doping of GQDs using gamma irradiation is reported. GQDs were irradiated in the presenceof the different ethylenediamine (EDA) amounts (1 g, 5 g, and 10 g) and the highest % of N wasdetected in the presence of 10 g. N-doped GQDs emitted strong, blue photoluminescence (PL).Photoluminescence quantum yield was increased from 1.45, as obtained for non-irradiated dots,to 7.24% for those irradiated in the presence of 1 g of EDA. Modified GQDs were investigated asa PL probe for the detection of insecticide Carbofuran (2,2-Dimethyl-2,3-dihydro-1-benzofuran-7-yl methylcarbamate) and herbicide Amitrole (3-amino-1,2,4-triazole). The limit of detection was5.4 µmol L−1for Carbofuran. For the first time, Amitrole was detected by GQDs in a turn-off/turn-onmechanism using Pd(II) ions as a quenching agent. First, Pd(II) ions were quenched (turn-off) PLof GQDs, while after Amitrole addition, PL was recovered linearly with Amitrole concentration(turn-on). LOD was 2.03 µmol L−1. These results suggest that modified GQDs can be used as anefficient new material for Carbofuran and Amitrole detection. Furthermore, the phototoxicity of dotswas investigated on both Gram-positive and Gram-negative bacterial strains. When bacterial cellswere exposed to different GQD concentrations and illuminated with light of 470 nm wavelength, thetoxic effects were not observed.

abstract = "Structural modification of different carbon-based nanomaterials is often necessary toimprove their morphology and optical properties, particularly the incorporation of N-atoms ingraphene quantum dots (GQDs). Here, a clean, simple, one-step, and eco-friendly method forN-doping of GQDs using gamma irradiation is reported. GQDs were irradiated in the presenceof the different ethylenediamine (EDA) amounts (1 g, 5 g, and 10 g) and the highest % of N wasdetected in the presence of 10 g. N-doped GQDs emitted strong, blue photoluminescence (PL).Photoluminescence quantum yield was increased from 1.45, as obtained for non-irradiated dots,to 7.24% for those irradiated in the presence of 1 g of EDA. Modified GQDs were investigated asa PL probe for the detection of insecticide Carbofuran (2,2-Dimethyl-2,3-dihydro-1-benzofuran-7-yl methylcarbamate) and herbicide Amitrole (3-amino-1,2,4-triazole). The limit of detection was5.4 µmol L−1for Carbofuran. For the first time, Amitrole was detected by GQDs in a turn-off/turn-onmechanism using Pd(II) ions as a quenching agent. First, Pd(II) ions were quenched (turn-off) PLof GQDs, while after Amitrole addition, PL was recovered linearly with Amitrole concentration(turn-on). LOD was 2.03 µmol L−1. These results suggest that modified GQDs can be used as anefficient new material for Carbofuran and Amitrole detection. Furthermore, the phototoxicity of dotswas investigated on both Gram-positive and Gram-negative bacterial strains. When bacterial cellswere exposed to different GQD concentrations and illuminated with light of 470 nm wavelength, thetoxic effects were not observed.",

AB  - The combination of two imaging modalities in a single agent has received increasing attention during the last few years, since its synergistic action guarantees both accurate and timely diagnosis. For this reason, dual-modality contrast agents (DMCAs), such as radiolabeled iron oxide (namely Fe3O4) nanoparticles, constitute a powerful tool in diagnostic applications. In this respect, here we focus on the synthesis of a potential single photon emission computed tomography/magnetic resonance imaging (SPECT/MRI) DMCA, which consists of Fe3O4 nanoparticles, surface functionalized with 2,3-dicarboxypropane-1,1-diphosphonic acid (DPD) and radiolabeled with 99mTc, [99mTc]Tc-DPD-Fe3O4. The in vitro stability results showed that this DMCA is highly stable after 24 h of incubation in phosphate buffer saline (~92.3% intact), while it is adequately stable after 24 h of incubation with human serum (~67.3% intact). Subsequently, [99mTc]Tc-DPD-Fe3O4 DMCA was evaluated in vivo in mice models through standard biodistribution studies, MR imaging and gamma-camera imaging. All techniques provided consistent results, clearly evidencing noticeable liver uptake. Our work documents that [99mTc]Tc-DPD-Fe3O4 has all the necessary characteristics to be a potential DMCA.

AB  - The study of the interactions between nanoparticles (NPs) and proteins has had a pivotal role in facilitating the understanding of biological effects and safe application of NPs after exposure to the physiological environment. Herein, for the first time, the interaction between L-methionine capped silver nanoparticles (AgMet), and bovine serum albumin (BSA) is investigated in order to predict the fate of AgMet after its contact with the most abundant blood transport protein. The detailed insights into the mechanism of interaction were achieved using different physicochemical techniques. The UV/Vis, TEM, and DLS were used for the characterization of the newly formed “entity”, while the kinetic and thermodynamic parameters were utilized to describe the adsorption process. Additionally, the fluorescence quenching and synchronous fluorescence studies enabled the prediction of the binding affinity and gave us insight into the influence of the adsorption on the conformation state of the BSA. According to the best of our knowledge, for the first time, we show that BSA can be used as an external stabilizer agent which is able to induce the peptization of previously agglomerated AgMet. We believe that the obtained results could contribute to further improvement of AgNPs’ performances as well as to the understanding of their in vivo behavior, which could contribute to their potential use in preclinical research studies.

AB  - The essential amino acid tryptophan (Trp) undergoes catabolism through several pathways, producing biologically active metabolites that significantly impact physiological processes. The metabolic pathway responsible for the majority of Trp catabolism is the kynurenine synthesis pathway (KP). Serotonin and melatonin are among the most essential Trp pathways degradation products. It has emerged that a strong relationship exists between alterations in Trp metabolism and the onset and progression of atherosclerosis and diabetes. Atherosclerosis is a chronic inflammatory disease of the small and medium arteries wall caused by maladaptive local immune responses, which underpins several cardiovascular diseases (CVD). Systemic low-grade immune-mediated inflammation is implicated in atherosclerosis where pro-inflammatory cytokines, such as interferon-γ (IFN-γ), play a significant role. IFN-γ upregulates the enzyme indoleamine 2,3-dioxygenase (IDO), decreasing serum levels of the Trp and increasing metabolite levels of kynurenine. Increased IDO expression and activity could accelerate the atherosclerosis process. Therefore, activated IDO inhibition could offer possible treatment options regarding atherosclerosis management. Diabetes is a chronic metabolic disease characterized by hyperglycemia that, over time, leads to severe damage to the heart, blood vessels, eyes, kidneys, and peripheral nerves. Trp serum levels and lower activity of IDO were higher in future type 2 diabetes (T2DM) patients. This article reviews recent findings on the link between mammalian Trp metabolism and its role in atherosclerosis and diabetes and outlines the intervention strategies.

AB  - Even though type 2 diabetes mellitus (T2DM) represents a worldwide chronic health issue that affects about 462 million people, specific underlying determinants of insulin resistance (IR) and impaired insulin secretion are still unknown. There is growing evidence that chronic subclinical inflammation is a triggering factor in the origin of T2DM. Increased C-reactive protein (CRP) levels have been linked to excess body weight since adipocytes produce tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6), which are pivotal factors for CRP stimulation. Furthermore, it is known that hepatocytes produce relatively low rates of CRP in physiological conditions compared to T2DM patients, in which elevated levels of inflammatory markers are reported, including CRP. CRP also participates in endothelial dysfunction, the production of vasodilators, and vascular remodeling, and increased CRP level is closely associated with vascular system pathology and metabolic syndrome. In addition, insulin-based therapies may alter CRP levels in T2DM. Therefore, determining and clarifying the underlying CRP mechanism of T2DM is imperative for novel preventive and diagnostic procedures. Overall, CRP is one of the possible targets for T2DM progression and understanding the connection between insulin and inflammation may be helpful in clinical treatment and prevention approaches.

AB  - Organophosphate-based pesticides have remarkably contributed to the agriculture industry, but their toxicity has a large negative impact on the environment as well as on the health of humans and other living organisms. Most of the methods developed to remedy the organophosphate pesticide toxicity are very time-consuming and are based on their adsorption onto different materials and/or their degradation to nontoxic species. In this study, detoxification of three structurally different organophosphate pesticides was investigated using an NU-1000 metal–organic framework. We showed that NU-1000 is an excellent agent for fast (average time ≤ 3 min) and effective removal of organophosphate pesticides with an aromatic heterocyclic moiety. In particular, superior detoxification of chlorpyrifos solution after NU-1000 treatment was achieved after only 1 min. The combination of experimental and computational methods revealed that the synergic effects of sorption and hydrolysis are responsible for the superior removal of CHP by NU-1000. The sorption process occurs on the Zr node (chemisorption) and pyrene linkers (physisorption) following pseudo-first-order kinetics during the first minute, and a pseudo-second-order model fits the entire time range. The multilayer adsorption of chlorpyrifos or its hydrolyzed product, 3,5,6-trichloro-2-pyridinol, takes place on a pyrene linker, whereas the aliphatic part of the molecule remains chemisorbed on the Zr node. Such unique synergy between induced sorption and hydrolysis of chlorpyrifos by NU-1000 results in its fast and effective removal with rapid detoxification in non-buffered solutions.
