AbstractObjectiveIn singleton pregnancies, the use of cell‐free DNA (cfDNA) analysis as a screening test for common fetal trisomies has spread worldwide though we still lack sufficient data for its use in triplet pregnancies. The objective of this study is to assess the performance of cfDNA testing in detecting fetal aneuploidies in triplet pregnancies as a first‐tier test.MethodWe performed a retrospective cohort study including data from pregnant women with a triplet pregnancy who underwent cfDNA testing between May 1, 2017, and January 15, 2020. cfDNA was obtained by massive parallel sequencing (VeriSeq NIPT solution; Illumina®). The objectives of the study were to assess the diagnostic performance of cfDNA testing for trisomy 21 (T21) (primary outcome), trisomy 18 (T18) and 13 (secondary outcomes).ResultsDuring the study period, cfDNA testing was performed in 255 women with triplet pregnancy, of which 165 (64.7%) had a neonatal outcome available. Three tests were positive for T21, one of which was confirmed by an antenatal karyotype, and the other was confirmed at birth. The third case did not undergo an invasive procedure and was not confirmed at birth (false positive). In one case, cfDNA testing was positive for T18 and was confirmed by an antenatal karyotype. There were no cases of trisomy 13 in the cohort. The no‐call rate was 2.4% at first sampling. Fifty‐eight (22.7%) women had embryo reduction, which in 40 (69%) of whom was performed after the cfDNA test result.ConclusioncfDNA testing could be offered as primary screening for main fetal aneuploidies in triplet pregnancies after provision of appropriate patient information.

Published: March 2024

AbstractComposite solid propellant is a kind of viscoelastic composite with high filling ratio and multi‐scale composition characteristics, and its macroscopic mechanical properties strongly depend on the microstructure of the propellant materia. However, with the increasing complexity of composition, structure and properties of composite solid propellants, the traditional research paradigm based on experimental observation, theoretical modeling and numerical simulation has encountered new scientific challenges and technical bottlenecks in the mechanical behavior analysis, charge design and manufacturing of composite solid propellants. Among them, the problems such as insufficient experimental observation, lack of theoretical model, limited numerical analysis and difficult verification of results restrict the development of composite solid propellants in future‐oriented engineering applications to a certain extent. The data‐driven computational mechanics method can directly establish complex relationships between variables from high‐dimensional and high‐throughput data, which can capture trends that are difficult to be found by traditional mechanics research methods, and has inherent advantages in the analysis, prediction and optimization of complex systems. This paper mainly reviews and evaluates the research of neural network based modeling, model‐free data‐driven calculation and data‐driven multi‐scale calculation, which provides the correct direction for the subsequent research of multi‐scale mechanical behavior of composite solid propellants based on data‐driven.

AbstractIntroductionThe Society of Nuclear Medicine and Molecular Imaging (SNMMI) provides appropriate use criteria (AUC) for prostate‐specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) which include guidance on imaging in newly diagnosed prostate cancer and in patients with biochemically recurrent (BCR) disease. This study aims to examine trends in PSMA implementation and the prevalence and outcomes of scans ordered in scenarios deemed rarely appropriate or not meeting SNMMI AUC.MethodsWe retrospectively identified patients who were diagnosed with presumptive National Comprehensive Cancer Network unfavorable intermediate, high, or very high risk prostate cancer, patients who underwent staging for BCR, and all patients staged with PSMA between July 2021 and March 2023. Positivity was validated by adherence to a predetermined reference standard.ResultsThe frequency of PSMA use increased in initial staging from 24% to 80% and work‐up of BCR from 91% to 99% over our study period. In addition, 5% (17/340) of PSMA scans ordered for initial staging did not meet AUC and 3% (15/557) of posttreatment scans were deemed rarely appropriate. Initial staging orders not meeting SNMMI AUC resulted in no positivity (0/17), while rarely appropriate posttreatment scans were falsely positive in 75% (3/4) of cases. Urologists (53%, 17/32) comprised the largest ordering specialty in rarely appropriate use.ConclusionThe frequency of PSMA use rose across the study period. A significant minority of patients received PSMA PET/CT in rarely appropriate scenarios yielding no positivity in initial staging and significant false positivity post‐therapy. Further education of providers and electronic medical record‐based interventions could help limit the rarely appropriate use of PET imaging.

AbstractA 37‐year‐old woman, 25 weeks pregnant, experienced sudden massive hemoptysis. She had a background history of systemic lupus erythematosus (SLE) and past pulmonary tuberculosis (PTB). Emergency intubation was necessary, and bronchoscopy revealed blood pooling in both main bronchi, with active bleeding from the right upper lobe bronchus. Urgent computed tomography (CT) angiography of the bronchial artery identified a bleeding source and was successfully embolized. Antifungal and anti‐tuberculous therapy was initiated based on bronchoalveolar lavage results. Despite initial improvement, hemoptysis recurred after the third week, leading to repeat embolization, followed by a caesarean section and right upper lobectomy. Both mother and baby survived, remaining well at a 6‐week follow‐up, emphasizing the complexities of managing recurrent hemoptysis during pregnancy and potential drug interactions.

AbstractThe acidic soils of western Newfoundland require liming for successful production of most crops. Locally sourced paper mill waste wood ash (WA) and paper sludge (SL) have potential as cheaper alternatives to limestone (LIME). Two greenhouse experiments evaluated WA and SL as liming and soil conditioning amendments for annual ryegrass (Lolium multiflorum) production. At 55 days after seeding, soil pH in WA (6.2 and 6.3) and wood ash and paper sludge (WASL) (6.0 and 6.3) were not different from that in LIME (6.0 and 6.5) for Experiments 1 and 2, respectively. However, pH in SL was 0.4 and 0.3 points lower than in LIME. Compared to LIME, WA, SL, and WASL produced 31%–52% and 57%–74% greater biomass yield in Experiments 1 and 2, respectively. N uptake was greater in WA (60 and 129 kg N ha−1) and WASL (51 and 97 kg N ha−1) compared to LIME (40 and 85 kg N ha−1), in Experiments 1 and 2, respectively. SL did not differ from LIME in Experiment 1, but reduced N uptake by 57% in Experiment 2. The results show significant potential of WA as an alternative amendment for liming and yield improvement of annual ryegrass grown in NL podzolic soils. However, SL has limited potential due to the risk of increasing N immobilization and residual soil mineral N when growing conditions are limiting. Combining SL with WA or biochar seemed to alleviate these risks. Overall, the adoption of these amendments for field production systems warrants serious consideration, following supplemental field studies to determine optimal application rates and timing.

AbstractDengue, a life‐threatening Flavivirus infection, is rampant across 128 tropical and subtropical regions, annually afflicting millions and causing 20,000 deaths due to inadequate treatments. Despite the FDA‐approved Dengvaxia vaccine, its limitations necessitate novel drug development. Notably, the enzymatic nature of the NS5 protein (PDB ID: 3p97) within DENV, responsible for viral RNA synthesis, makes it a prime drug target. Employing Pharmacoinformatics, Molecular Dynamics Simulations, Quantum Mechanics, and network pharmacology, we screened compounds from NuBBE, the Brazilian Amazon Plant Database, along with reported dengue compounds. Docking yielded promising scores (−11.1 to −2.8) and (−11 to −3.1) kcal/mol, respectively. From 1310 phytochemicals, top compounds emerged: Ramosin, Pectolinarin, hinokinin, and sesamin, boasting scores of −11, −11, −9.7, and −9.6, surpassing Acetaminophen's −5.8. Validated post‐docking interactions used 100 ns Molecular Dynamics Simulations and quantum mechanics. Pharmacokinetics and Toxicity analysis aligned with ADME norms, showing no undue toxicity. Network pharmacology unveiled connections between bioactive chemicals and disease targets. This investigation uncovers the potential of these compounds to inhibit DENV‐3 NS5 protein. In vitro, in vivo, and cell line assays are crucial next steps for specific anti‐dengue drug development.

AbstractIndeed, considerable efforts have been made in the domain of silver nanoparticles, including the construction and wide‐ranging applications. This work involves the synthesis and characterization of salophen anchored silver nanoparticles (AgNPs), and its utilization for selective detection of Fe2+ and Cu2+ ions in DMSO. These AgNPs were synthesized by the reduction of Ag+ ions with salophen ligand, and were characterized by different techniques which include UV‐visible, fluorescence, FTIR, SEM, EDX, TEM, PXRD, DLS, and zeta potential. The negative zeta potential value of −19.6 mV evidenced the stability of the AgNPs. These AgNPs were found to sense Fe2+ and Cu2+ ions selectively in DMSO solution at various concentrations. Instant color change from olive to brown as well as olive to light olive was observed while detecting Fe2+ and Cu2+ ions by the nanoprobe, respectively. UV‐visible and fluorescence spectroscopic investigations were carried out to establish the sensing ability of the nanoprobe. Additionally, AgNPs revealed promising antibacterial activity selectively against gram‐negative bacteria over gram‐positive bacteria. Thus, our approach opens up a new track to design novel and operative functionalized nanomaterials for real‐life sensing and biomedical applications.

Published: March 2024

AbstractIn vitro bioequivalence assessment of paracetamol tablets was carried out by differential pulse voltammetry (DPV) and amperometry using a multiwalled carbon nanotube modified glassy carbon electrode (GCE/MWCNT). For the DPV developed method, samples were collected from the USP paddle apparatus, while amperometric measurements were carried out in situ. The DPV method was validated in three supporting electrolytes (per in vitro bioequivalence guidelines) by measuring the recovery from standard solutions and paracetamol tablet solutions, while precision was evaluated through the RSD (n=6). In HCl pH 1.2 solution the LOD and LOQ were 48 nM and 160 nM, respectively and the linear range was between 0.18–2.2 μM. In acetate buffer pH 4.5 the LOD and LOQ were 15 nM and 51 nM, respectively and the linear range was between 88 nM–880 nM. And in phosphate buffer pH 6.8 the LOD and LOQ were 4.6 nM and 15 nM, respectively and the linear range was between 88 nM–880 nM. Recovery values were between 95 and 105 % and precision values were less than 5 %. Results showed that both methods were effectively applied for the analysis of samples.

Published: March 2024

AbstractMolecular self‐association of monomers with multifaceted cross‐linkers, opens new possibilities for the development of various supramolecular‐networks that enable to participate in different functions. Plaques associated with senility that form in the brains of Alzheimer′s patients are mainly composed of beta amyloid (Aβ). It can be assumed that there must be a nucleation site which through reverse folding initiate to aggregate this Aβ plaque. It has been reported KLVFFA motif of Aβ sequence plays an important role as the amylogenic unit for Alzheimer disease. In order to identify the shortest sequence that would initiate the nucleation for such aggregation, we have synthesized N‐terminal protected two two‐residue peptides [Hex‐Phe(1)‐Phe(2)‐OMe: (FF)] and [Hex‐Phe(1)‐Ala(2)‐OMe: (FA)] an important fragment of KLVFFA motif. Using various microscopic and biophysical approaches, including measuring the hydrodynamic radii, it is observed that in fully aqueous condition in comparison to FA, FF nucleates higher degree of aggregates, along with substantial formation of dendrimeric amyloid fibrils, which has been elegantly visualized in Congo‐red assay through formation of distinct apple‐green birefringence. Such an observation leads to hypothesize that the ‘di‐phenylalanine’ unit (FF) plays a crucial role as the nucleation site towards attaining the aggregate for formation of the Aβ plaque through reverse folding.

Published: March 2024

AbstractAzines are organic molecules with a C=N−N=C functional range of applications. But the conventional azines synthesis process requires a high reaction temperature and long reaction time combined with complex reaction facilities, so the synthesis process needs to be further improved in terms of economic efficiency and process simplification. Here, we demonstrate a structurally well‐defined inorganic ligand Ni compound, (NH4)4[NiMo6O18(OH)6](Ni‐POMs). The catalysts show good activity towards the reaction of carbonyl compounds, and the corresponding products can be obtained in yields up to about 90 %. In this condition, the majority of the aldehydes (aromatic and aliphatic) can be reacted, and the products are obtained in high yields. Density functional theory (DFT) looked into the process by which benzaldehyde and hydrazine hydrate reacted on the surface of Ni‐POMs. It was calculated that the whole reaction goes through two stages and the activation energy of the whole reaction is −6.72 kcal/mol. Thus, from experiment to calculation, a complete structure of the catalytic reaction cycle has been constructed.

AbstractThis study is based on green synthesized nanomaterials that increase fluorescence intensity in the study of the anticancer drug palbociclib. The basis for the nanomaterials was the use of alumina/nickel oxide nanocomposite (alumina/NiO NCS) biogenically produced from millet seed extract. The proposed materials improved the spectrofluorimetric method for the study of the breast cancer drug palbociclib (PAL) in its real powder and capsules. The amplification properties of the developed spectrofluorimetric system depend on the unique optical properties of the alumina/NiO NCS. Fluorescence detection was determined at λex 260 and at λem 430 nm. The effect of surfactant (sodium dodecyl sulfate, SDS) was investigated, and the results obtained with the PAL alumina/NiO/SDS showed linearity of 1.0–800
g/mL for PAL samples with a correlation coefficient of r>0.999. The aforementioned fluorescence approach showed lower detection and quantification of 0.03 and 1.0
g/mL, respectively. The proposed system was potentially efficient for the determination of PAL with an excellent percent recovery of 99.50±0.5 %. The effect of some co‐formulated interfering substances such as crystalline cellulose, starch, silicon dioxide magnesium stearate, lactose and gelatine that present in the capsules was investigated and no remarkable difference was found during the assay process of PAL. The method was validated to ensure its suitability and showed high sensitivity and accuracy for the detection of PAL.

AbstractIn the current study, N1‐N4‐bis (3‐(trimethoxysilyl) propyl) butane‐1,4‐diammonium trinitromethanide on titanium dioxide {TiO2−Bis [TMS−NH2+ C(NO2)3−]} was synthesized and characterized using a variety of techniques including energy dispersive X‐ray analysis (EDX), fourier transform infrared spectroscopy (FT‐IR), thermo gravimetric analysis (TGA), field emission scanning electron microscopy (FESEM), and X‐ray diffraction (XRD). Then TiO2−Bis [TMS−NH2+ C(NO2)3−] was used as an efficient nano‐catalyst in the one‐pot synthesis of 1,2,4‐triazolo[4,3‐a] pyrimidine derivatives at 120 °C under the solvent‐free conditions with good to excellent yields. Easy separation of the products from the catalyst, short period of the reaction times, and reusability of the catalyst are among the most important features of the reported method.

Authors: Dinesh  , Singh Satyendra 
Published: March 2024

AbstractOrganic‐inorganic metal halide single crystals have attracted a lot of attention due to their flexible structural design and excellent optoelectronic applications. This study details the synthesis of copper‐based [(CH3)4N]2CuBr4 hybrid metal halide single crystals via a slow evaporation method. The crystal structure, crystal habit, chemical groups, intermolecular interactions, electrical properties of the sample were studied via single crystal x‐ray diffraction, scanning electron microscopy, Raman and Fourier transform infrared spectrometer, Hirshfeld surface analysis, impedance spectroscopy, and modulus spectroscopy, respectively. An orthorhombic crystal system with the non‐centrosymmetric space group Pna21 was identified at room temperature. The deformation in the tetrahedra was calculated by the bond angle and bond length deformation index. The Cole‐Cole plot displayed the existence of depressed semicircles, which indicated the predominant distribution of grains, further confirmed by the SEM image. The deformed semi‐circular arcs on the electric modulus curve undeniably prove that the bulk effect dominates the material‘s electrical properties. Significantly, the compound presents a phase transition at ~240 K and excellent thermal stability up to a temperature of 400 K. Therefore, our research sheds light on the temperature dependence of electrical responses in these hybrid crystals and gives inspiration for the development of single crystal‐based efficient energy devices.

AbstractBackgroundYusho is a 1968 mass food poisoning that was caused by the ingestion of rice oil contaminated with dioxins and related organochlorines. We previously reported that keishibukuryogan (KBG) administration was effective for improvement of the symptoms of Yusho patients. This study used responder analysis to more deeply elucidate the effectiveness of KBG.MethodThe data analyzed in the study were collected from our previous clinical study done to predict response to KBG treatment. The patients were divided into responders and non‐responders based on whether their symptoms improved after taking KBG. We assessed baseline patient characteristics and the intensity of general fatigue and dermatological, neurological, and respiratory symptoms. Further, we used SF‐36 to evaluate Quality of Life (QOL).ResultsOf the 42 patients who completed the previous study, 27 were responders and 15 non‐responders, with no significant differences in the patient characteristics. The general fatigue, dermatological symptoms, and respiratory symptoms of responders were significantly improved at month 3 of treatment. Analysis of the eight QOL domain profiles of SF‐36 showed that the general health of responders was significantly improved from baseline to month 3 compared with non‐responders, as was vitality from baseline to month 1. Moreover, the mental health of responders significantly improved from baseline to months 1 and 3.ConclusionsKeishibukuryogan was not only effective for symptoms such as general fatigue, dermatological symptoms, and respiratory symptoms, but also for the mental health of Yusho patients, which indicates that it would be a good first‐choice Kampo medicine for the treatment of these patients.
