Authors: Tian Yang , Sun Zhongwen , Sun Jiehui , Zhu Jinhai , Guo Yuan 
Published: December 2023

Abstract
Because of the characteristics of high temperature resistance, high thermal stability, no component overflow after curing, Benzoxazine resin-based composite is widely used in the high temperature working area such as the rear section of the domestic C919 large passenger aircraft involved in the development process. In this paper, the influence of curing process conditions such as curing temperature, curing pressure and holding time on the mechanical properties of benzoxazine resin-based composites was evaluated by using the autoclave curing process, in order to select the optimal curing process conditions, and the hygrothermal aging property of the material at 71℃ was also evaluated. The results show that the curing temperature has little effect on the compressive strength and shear strength. With the decrease of curing pressure, the compressive and shear properties of the materials decreased slightly. With the increase of holding time, the compression strength increases slightly, the compression modulus decreases slightly, and the shear strength changes little. Under the condition of 71℃, the reduction of interlaminar shear strength is less than 10%, so the material has excellent performance in the aspect of resistance to damp and anti-aging property.
Upcycling acrylonitrile-butadiene-styrene Vitrimer ‘in melt’ using a dynamic crosslinker
Authors: Bose Suryasarathi 
Published: December 2023

Abstract

The perception of a sustainable plastic closed-loop circular economy hinges on the transformation of post-consumer recycled (PCR) commodity plastics. Among those, acrylonitrile butadiene styrene (ABS), a widely utilized engineering plastic, can be economically and efficiently upcycled to mark a significant step forward. Very few concrete solutions have been proposed so far for adopting end-of-life ABS into reusable products, mainly due to deterioration in mechanical properties of PCR ABS after subsequent recycling. Our approach introduces a distinctive strategy of creating durable and recyclable dynamic covalent adaptable network (CAN) termed as PCR ABS Vitrimers, all achieved through a melt-based process which holds promise for industrial viability and economic feasibility. In a first of its kind, a designer bio-based crosslinker, imine containing castor oil (iCO) having dynamic imine linkages as CAN was synthesized to form PCR ABS Vitrimers ‘in melt’ resulting in an upcycled ABS with 15% and 19% improvement in ultimate tensile strength and Young’s modulus respectively, in the Vitrimers. Our designer giant crosslinker, besides offering a transient network imparts re-processibility to the formed PCR ABS Vitrimers via melt with better mechanical integrity. This research endeavours to tackle a long-standing obstacle in upcycling PCR ABS in its melt state by producing a more robust, resilient, and solvent-resistant material derived from PCR ABS waste.
Unusual platinum(III) valence state stabilized through the iodide-bridged three-center four-electron bonding

Abstract
One of the goals in synthetic chemistry is to obtain compounds featuring unusual valence states that are stable under ambient conditions. At present, stabilizing unusual Pt(III) states is considered difficult, except through direct Pt–Pt bonding such as that in platinum-blues or organometallization using bulky ligands. Pt(III) stabilization is also very difficult in halogen-bridged metal complex chains (MX-Chains). Herein, the iodide-bridged Pt(III) dimer compound [Pt2(en)4I3]I3 (3) (en = ethylenediamine), which is prepared by iodine oxidation of [PtII(en)2] (1), has been successfully synthesized and characterized. This compound is stable and is obtained as diamond-shaped single crystals with a lustrous emerald-green color under reflected light and a red color under transmitted light. The two Pt centers are crystallographically equivalent and can be assigned as Pt(III). Density functional theory calculations reveal that the Pt(III) state is stabilized by the three-center four-electron (3c-4e) bonding in the Pt–I–Pt core (dz2–pz–dz2), in addition to the very strong antiferromagnetic state. This type of bonding stabilization does not appear in MX-Chains. The experimental polarized reflection spectra show the Pt(III) state character and are in agreement with the simulated spectra. The stabilization of Pt(III) through a 3c-4e bonding mechanism is novel; thus, this work provides new insight for stabilizing the unusual Pt(III) state.

Efficacy of 5-Fluorouracil (5-FU) and Low Molecular Weight Heparin (LMWH) in high-risk pediatric retinal detachment; Randomized Clinical Trial
Authors: Nasr Mohamed Kamal Hussein Nasr , Abdelhadi Ahmed Mahmoud , Bessa Amr Saad Mohamed , Ibrahim Tamer Moussa 
Published: December 2023

Abstract
Background:
Pediatric rhegmatogenous retinal detachments (PRRDs) are complex, rare occurrences and are often related to trauma or congenital abnormalities. Children often do not recognize or report symptoms of retinal detachment. Thus at presentation, PRRD is typically advanced often with macular involvement, proliferative vitreoretinopathy (PVR), chronic duration, and poor visual acuity. Because 5-FU and LMWH are effective in different aspects in the PVR process, it was believed that a syngergistic approach to the prevention of PVR would be advantageous.
Methods:
After informed consent, children under 14 years of age with high-risk PRRD underwent pars plana vitrectomy and silicone oil injection with scleral buckle divided into 2 groups in prospective randomized trial. Group A received intraoperative infusion of 5-FU (200 µg/ml) and LMWH (5 IU/ml), group B received infusion of normal saline. Primary outcome was occurrence of recurrent PRRD within 12 weeks, secondary outcomes were occurrence of PVR, best corrected visual acuity (BCVA), number and timing of secondary procedures within 12 weeks.
Results:
The study included 42 eyes of 41 patients, 21 in group A and 21 in group B, the duration of PRRD ranged from 0.5-7 months in group A and 0.25-5 months in group B.The rate of recurrent PRRD was higher in group B 33% compared to 19% in group A (p = 0.292). The mean timing of occurrence of recurrent PRRD was 9.5 ± 5 weeks in group A compared to 2.86 ± 2.41 weeks in group B (p = 0.042), more patients in group B ended up with more advanced PVR (p = 0.038), BCVA was hand movement (HM) only in all cases preoperatively and improved to HM-0.3 Snellen in group A compared to light perception (PL)-0.1Snellen in group B (p = 0.035), there was no difference in any of secondary procedures but with later timing in group A 9.71 ± 3.73 weeks than in group B 4.0 ± 2.83 weeks (p = 0.042).
Conclusion:
This study concluded that the use of the 5-FU and LMWH combination in high risk PRRD resulted in lower rate of postoperative PVR, later recurrence of PRRD and better final BCVA.

Abstract
Dimethylsulfoniopropionate (DMSP) catabolism by ubiquitous marine Roseobacters is important in global carbon and sulfur cycling, chemotaxis, and climate-active gas production. Many Roseobacters contain competing DMSP demethylation and cleavage pathways, the latter generating the climate-cooling gas dimethylsulfide (DMS). The mechanism partitioning flux through these pathways, referred to as “the switch”, is unknown. Here, we identify a FadR family transcriptional regulator “DmdR” in Roseobacters that represses transcription of the DMSP demethylation gene dmdA and acuI, central to DMSP cleavage pathways, under low intracellular DMSP levels. Increased DMSP levels induces DMSP cleavage and accumulation of the toxic intermediate and AcuI substrate acryloyl-CoA. DmdR binds acryloyl-CoA as its effector and derepresses dmdA-acuI transcription. Roseobacterial DmdR-dependent regulation, together with transcriptional and kinetic regulation of DMSP cleavage, likely ensures cellular DMSP concentrations that allow its antistress functions and accelerated DMSP demethylation and catabolism of toxic cleavage pathway intermediates at higher DMSP levels. In other abundant marine bacteria that lack dmdA, e.g., Oceanospirillales, DmdR is predicted to still regulate acuI transcription and, thus, acryloyl-CoA catabolism/detoxification. DmdR regulation is widespread in Earth’s oceans and their margins and is an important step in global biogeochemical cycling and climate-active gas production.

Abstract

The transition towards clean transport requires energy carriers tailored to their application. Promising energy carriers for heavy-duty transportation are synthetic fuels. Here, we introduce hydroformylated Fischer-Tropsch (HyFiT) fuels designed to simultaneously address the four key challenges of current synthetic fuels: (1) HyFiT-fuel production closes the carbon cycle in a flexible way by employing either biomass or carbon dioxide as feedstock, while being scalable through mature technologies. (2) HyFiT-fuels are shown experimentally to comply with global fuel standards. Material compatibility is demonstrated for two standard sealing materials, enabling the retrofit of today’s vehicle fleets. (3) Vehicle testing in a light commercial van shows that HyFiT-fuels substantially reduce combustion-induced particulate matter and nitrogen oxides. (4) A well-to-wheel life cycle assessment finds that HyFiT-fuels enable the transition to net-zero greenhouse gas emissions, showing simultaneously a favorable profile in a range of other environmental parameters, and can thereby complement electrification for heavy-duty long-haul transportation.
Barriers to Substance Use Treatment for Individuals with Substance Use Disorders
Authors: Hudson Joseph Robert , Manuel Jennifer 
Published: December 2023

Abstract
Background
Although residential substance use treatment has been shown to improve substance use and other outcomes, most with substance use disorders (SUDs) never seek professional treatment. Much research has been done on the barriers to seeking treatment. However, greater understanding is needed of the similarities and differences in the perceptual barriers to treatment held by clients and staff.
Methods
This paper (1) identifies and compares adult client vs. staff perceptions of barriers to substance use treatment, and (2) compares perceptions between an urban vs. rural treatment setting. Secondary analysis of transcripts of semi-structured interviews with clients (n = 61) and staff (n = 37) from a residential substance use treatment program in New York (urban) and in Virginia (rural). Transcriptions of interviews were formally analyzed by two analysts using framework analysis.
Results
The major results indicate that personal barriers (83%) were cited more frequently than interpersonal (15%) and structural barriers (24%). Staff were more likely to cite interpersonal barriers (19% vs. 11%) and structural barriers (29% vs. 20%) than were clients.
Conclusions
These findings further demonstrate that personal culpability and self-blame are often felt by those with SUDs and this sentiment is often reinforced by treatment providers. Interventions are needed that can reduce the stigma of SUD’s, resulting in a shift away from the perception that barriers to treatment exist primarily at the personal level.

The ManhattAnt: Identification, distribution, and colony structure of a new pest in New York City, Lasius emarginatus
Authors: Kennett Samantha M , Seifert Bernard , Dunn Robert R , Pierson Todd W , Penick Clint A 
Published: December 2023

Abstract

A new ant species was discovered in the heart of New York City in 2011, which garnered national headlines and created the memorable nickname “ManhattAnt.” New York City is one of the oldest and largest cities in North America and has been the site of introduction for some of North America’s most damaging invasive pests. Nevertheless, there has been little follow up research on the ManhattAnt since its discovery, and it has yet to be formally identified. Here we use genetic and morphological approaches to confirm the identity of the ManhattAnt and characterize its introduced range and colony structure. Results from genetic analyses placed the ManhattAnt within the Lasius emarginatus species complex, and morphological comparisons ruled out closely related species to identify the ManhattAnt as the European ant L. emarginatus with 93–99% certainty depending on the nest sample. Since its initial discovery, the ManhattAnt has become one of the most common ants in New York City and has spread at a rate of 2km/yr into New Jersey and onto Long Island. Based on the climate it inhabits within its native range, L. emarginatus could expand to cover much of the eastern United states from Massachusetts to Georgia. Although many successful invasive ants display supercoloniality with little aggression between neighboring nests, we found no evidence that L. emarginatus colonies in New York City are supercolonial. Continued monitoring of L. emarginatus is warranted, as it has been increasingly reported as an indoor pest and is known to form mutualisms with honeydew producing pests of street trees.

Published: December 2023

Abstract
The aim of this study was to develop a three-dimensional (3D) cell model in order to evaluate the effectiveness of a traditional Chinese medicine decoction in the treatment of arthritis. Chondrocytes (ATDC5) and osteoblasts (MC3T3-E1) were 3D printed separately using methacryloyl gelatin (GelMA) hydrogel bioinks to mimic the natural 3D cell environment. Both cell types showed good biocompatibility in GelMA. Lipopolysaccharide (LPS) was added to the cell models to create inflammation models, which resulted in increased expression of inflammatory factors IL-1β, TNF-α, iNOS, and IL-6, and decreased expression of cell functional genes such as Collagen II (COLII), transcription factor SOX-9 (Sox9), Aggrecan, alkaline phosphatase (ALP), RUNX family transcription factor 2 (Runx2), Collagen I (COLI), Osteopontin (OPN), and bone morphogenetic protein-2 (BMP-2). The created inflammation model was then used to evaluate the effectiveness of Dangguiniantongtang (DGNT) decoctions. The results showed that DGNT reduced the expression of inflammatory factors and increased the expression of functional genes in the cell model, which was consistent with subsequent animal experiments. In summary, this study established a 3D cell model to assess the effectiveness of traditional Chinese medicine (TCM) decoctions, characterized the gene expression profile of the inflammatory state model, and provided a practical reference for future research on TCM efficacy evaluation for arthritis treatment.
Rapid, Sensitive, and Selective "ON-OFF" Detection of Fe3+ Ions Using Novel Acetalophanes and Their Applications in Real Samples

Published: December 2023

Abstract
Three novel acetalophanes 1a-c have been designed, synthesized and characterized. The receptors 1b-c, featuring bulky anthracene groups, displayed significant selectivity for Fe3+ ions, resulting in a turn-off fluorescence mode in a DMF-buffer solution. Conversely, the non-steric probe 1a could serve as a versatile sensor for the simultaneous detection of Fe3+ and Cu2+ ions in MeOH-buffer solution. The sensing mechanism for the capability of 1a was demonstrated to be different, as evidenced by the addition of cyanide ions. The probes with Fe3+ exhibited a sensing mechanism that resulted in the deprotection of acetals to the corresponding starting materials, as confirmed by 1H NMR, IR spectra and TLC analysis. The attractive features of these practical and efficient sensors are selectivity, sensitivity (limit of detection = 0.15 µM by 1a, 0.16 µM by 1b and 0.14 µM by 1c), rapid response (less than 5 seconds). The on-site monitoring of various real samples, including well water, apricot, and green tea, proved to be successful for the quantitative and cost-effective detection of Fe3+. The method demonstrated good precision, even in the presence of other interfering materials.

Abstract
Human retinal stem cells hold great promise in regenerative medicine, yet their existence and characteristics remain elusive. Here, we preformed single-cell multi-omics and spatial transcriptomics of human fetal retinas and uncovered a novel cell subpopulation, human neural retinal stem-like cells (hNRSCs), distinct from RPE stem-like cell and traditional retinal progenitor cells. These hNRSCs reside in the peripheral retina within the ciliary marginal zone, exhibiting substantial self-renewal and differentiation potential. We conducted single-cell and spatial transcriptomic analysis of human retinal organoids (hROs), and revealed hROs have remarkable similar hNRSCs consistent with fetal retina, capable of regenerating all retinal cells. Furthermore, we identified crucial transcription factors, notably MECOM, governing hNRSC commitment to neural retinogenesis and regulating hROs regeneration. Transplanting hRO-derived hNRSCs into the rd10 mouse of rapid retinal degeneration significantly repairs the degenerated retina and restores visual function. Together, our work identifies and characterizes a unique category of retinal stem cells from human retinas, underscoring their regenerative potential and promise for transplantation therapy.
Identifying the priorities for supervision by lived experience researchers: A Q sort study
Authors: Gupta Veenu , Eames Catrin , Bryant Alison , Greenhill Beth , Golding Laura , Day Jennifer , Fisher Peter 
Published: December 2023

Abstract
Background
Lived experience researchers draw on their lived experiences to inform and interpret their research. They bring complex service user and survivor histories to their work and must manage their health conditions and the interplay of their lived experiences with the research, population, and data they work with, as well as the more general challenges of being a researcher. They must navigate these dilemmas in addition to queries over their competency, due to issues relating to intersectionality and epistemic injustice. This justifies a motivation to better understand the experiences of lived experience researchers and develop appropriate and personalised supervision based on their preferences and needs.
Method
Q methodology was used to identify a collection of identity-related issues that impact lived experience researchers during PhD research. These 54 statements were presented to 18 lived experience researchers to prioritise as topics to explore to understand their subjective needs from supervision.
Results
Three distinct factors were found following an inverted factor analysis: Factor 1: Strengthening my identity, skills, growth, and empowerment; Factor 2: Exploring the emotional and relational link I have with the research and Factor 3: Navigating my lived and professional experiences practically and emotionally. The findings suggest that there are three types of lived experience researchers, each with different needs from supervision, suggesting the population is heterogeneous.
Conclusions
The research identified a deeper understanding of the subjective needs of lived experience researchers and highlights the importance of personalised supervision according to their individual needs, and preferences for supervision. The findings reinforce the importance of integrating a clinical dimension into supervision to support the needs of each lived experience researcher.
Time-Multiplexing Control of Boost Side Interleaved Multiport DC-DC Converter

Published: December 2023

Abstract
Multiport dc-dc converters (MPDC) can simultaneously convert the supply voltage to different levels. Multiport dc-dc converters are readily used in various industrial and commercial applications, such as UPS systems, electric vehicles, etc. For high-power applications, to improve the performance and efficiency of converters, the interleaving technique is used. For low-power applications, interleaved multiport dc-dc converters maintain ample power density in the system. This research paper showcases a bidirectional boost-side interleaved multiport dc-dc converter (BIMC). The converter presented provides two different voltage outputs, one stepped up and another stepped down. Through interleaving, the ripple in the input current has been reduced. The converter has become more fault-tolerant and can deliver basic operation even after a transistor failure. Through the bidirectional operation, power can flow from the buck side to the boost end of the converter in the absence of an input. Mathematical formulations, current, and voltage waveforms are derived and shown for both the outputs of the converter, i.e., the boost and buck outputs. Closed-loop control has been designed in order to achieve constant voltage operation. Simulation and hardware results are provided. A comparative study with the conventional MPDC has also been provided.
