Background
Many mammalian species have experienced range contractions. Following a reduction in distribution that has resulted in apparently small and disjunct populations, the Humboldt marten (Martes caurina humboldtensis) was recently designated as federally Threatened and state Endangered. This subspecies of Pacific marten occurring in coastal Oregon and northern California, also known as coastal martens, appear unlike martens that occur in snow-associated regions in that vegetation associations appear to differ widely between Humboldt marten populations. We expected current distributions represent realized niches, but estimating factors associated with long-term occurrence was challenging for this rare and little-known species. Here, we assessed the predicted contemporary distribution of Humboldt martens and interpret our findings as hypotheses correlated with the subspecies’ niche to inform strategic conservation actions.

Methods
We modeled Humboldt marten distribution using a maximum entropy (Maxent) approach. We spatially-thinned 10,229 marten locations collected from 1996–2020 by applying a minimum distance of 500-m between locations, resulting in 384 locations used to assess correlations of marten occurrence with biotic and abiotic variables. We independently optimized the spatial scale of each variable and focused development of model variables on biotic associations (e.g., hypothesized relationships with forest conditions), given that abiotic factors such as precipitation are largely static and not alterable within a management context.

Results
Humboldt marten locations were positively associated with increased shrub cover (salal (Gautheria shallon)), mast producing trees (e.g., tanoak, Notholithocarpus densiflorus), increased pine (Pinus sp.) proportion of total basal area, annual precipitation at home-range spatial scales, low and high amounts of canopy cover and slope, and cooler August temperatures. Unlike other recent literature, we found little evidence that Humboldt martens were associated with old-growth structural indices. This case study provides an example of how limited information on rare or lesser-known species can lead to differing interpretations, emphasizing the need for study-level replication in ecology. Humboldt marten conservation would benefit from continued survey effort to clarify range extent, population sizes, and fine-scale habitat use.

AbstractObjectiveJNK pathway‐associated phosphatase (JKAP) is previously reported to regulate immune/inflammatory process via T‐cell signaling, and closely involves in neurological diseases, while its implication in Parkinson's disease (PD) is unknown. Therefore, this study aimed to investigate the correlation of JKAP with Th1/Th2/Th17 cells and their clinical roles in PD patients, and then further explore the effect of JKAP on regulating CD4+ T‐cell differentiation in PD.MethodsTotally 50 PD patients and 50 age‐/gender‐matched controls were enrolled. Their blood samples were collected and proposed to ELISA and flow cytometry assays for JKAP, Th1, Th2, and Th17 measurements. In vitro, CD4+ T cells were isolated from PD patients then transfected with JKAP overexpression and knockdown Lentivirus, followed by detection of markers (CD25+ cell proportion, CD69+ cell proportion, IFN‐γ, IL10, and IL17).ResultsJKAP was downregulated in PD patients compared to controls, which also showed good potency to discriminate them. Besides, JKAP negatively correlated with Th1 and Th17 cell proportions, but did not associate with Th2 cell proportion in PD patients; Interestingly, JKAP did not correlated with Th1, Th2, or Th17 cell proportions in controls. Furthermore, JKAP correlated with some parts of unified Parkinson’s Disease Rating Scale (UPDRS) and Mini‐Mental State Examination (MMSE) score. In vitro, JKAP overexpression repressed CD4+ T‐cell activation and its differentiation into Th1 and Th17 cells in PD, while JKAP knockdown appeared opposite effect.InterpretationJKAP associates with disease risk and severity, correlates with Th1 and Th17 cells, and regulates CD4+ T‐cell activation/differentiation in PD.
Additive‐Free Energetic Film Based on Graphene Oxide and Nanoscale Energetic Coordination Polymer for Transient Microchip

Published: July 2021

AbstractTransient microchips have promising applications in data security and privacy protection. A simple fabrication process and short transient time are two crucial requirements for transient microchips. In this study, a facile drop‐casting method is used to develop a transient microchip based on an energetic film and a microheater on a substrate. It is found that the graphene oxide‐energetic coordination polymer composite based energetic film plays an important role in simplifying the fabrication process and achieving fast transient time due to its inherent film forming ability, strong binding to substrate, and highly energetic characteristics. The interlayer confinement effect of graphene oxide (GO) can significantly reduce the size of energetic coordination polymer (ECP) to nanometer scale. Van der Waals forces between GO layers and coordination bonds between GO and metal ions are responsible for the film formation ability. Furthermore, the reduction of ECP size and the compact stacking lay the foundation for the excellent combustion and pressure production performance of the energetic film. The strong adhesion of the energetic film and the substrate is confirmed by drop experiments. More importantly, the fabricated silicon based transient microchip can achieve self‐destruction within 1 second.

Published: July 2021

AbstractThe great interest in rechargeable Zn–air batteries (ZABs) arouses extensive research on low‐cost, high‐active, and durable bifunctional electrocatalysts to boost the sluggish oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). It remains a great challenge to simultaneously host high‐active and independent ORR and OER sites in a single catalyst. Herein a dual‐phasic carbon nanoarchitecture consisting of a single‐atom phase for the ORR and nanosized phase for the OER is proposed. Specifically, single Co atoms supported on carbon nanotubes (single‐atom phase) and nanosized Co encapsulated in zeolitic‐imidazole‐framework‐derived carbon polyhedron (nanosized phase) are integrated together via carbon nanotube bridges. The obtained dual‐phasic carbon catalyst shows a small overpotential difference of 0.74 V between OER potential at 10 mA cm−2 and ORR half‐wave potential. The ZAB based on the bifunctional catalyst demonstrates a large power density of 172 mW cm−2. Furthermore, it shows a small charge‐discharge potential gap of 0.51 V at 5 mA cm−2 and outstanding discharge‐charge cycling durability. This study provides a feasible design concept to achieve multifunctional catalysts and promotes the development of rechargeable ZABs.

Published: July 2021

AbstractPerovskite solar cells (PSCs) and organic photovoltaics (OPVs) have undergone rapid development within the last decade, exhibiting exciting properties such as high efficiency, flexibility, and the potential for large‐scale fabrication through roll‐to‐roll (R2R) processing. Despite this, operational stability is recognized to be an ongoing challenge as prolonged device lifetimes are scarcely observed. This instability can be narrowed down to both “intrinsic degradation” and “extrinsic degradation,” with exposure to moisture and oxygen having detrimental effects on device performance. A means of delaying the degradation of flexible PSC and OPV devices is through barrier encapsulation. Despite glass encapsulation exhibiting ideal barrier properties, the potential for flexible devices and high‐throughput R2R fabrication requires the development of flexible barrier materials and encapsulation strategies. These barriers must demonstrate outstanding moisture permeation resistance, high transparency, chemical and thermal stability, and must be able to withstand repeated mechanical deformation. Herein, the fundamental principles of PSC and OPV devices are initially discussed, highlighting the degradation mechanisms and current stability obstacles. A review of the latest flexible barrier materials and encapsulation strategies follows, introducing stability studies that have been undertaken on flexible PSCs and OPV, along with suggestions as to the direction that future research may take.

AbstractBackgroundAccelerated‐FEV1‐decline, defined as rate of decline in FEV1 > 64 ml/year, is a risk factor for asthma and chronic obstructive pulmonary disease in World Trade Center (WTC)‐exposed firefighters. Accelerated‐FEV1‐decline in this cohort is associated with elevated blood eosinophil concentrations, a mediator of Th‐2 response. We hypothesized that an association exists between Th‐2 biomarkers and FEV1 decline rate in those with accelerated‐FEV1‐decline.MethodsSerum was drawn from Fire Department of the City of New York (FDNY) firefighters 1–6 months (early) (N = 816) and 12–13 years (late) (N = 983) after 9/11/2001. Th‐2 biomarkers IL‐4, IL‐13, and IL‐5 were assayed by multiplex Luminex. Individual FEV1 decline rates were calculated using spirometric measurements taken: (1) between 9/11/2001 and 9/10/2020 for the early biomarker group and (2) between late measurement date and 9/10/2020 for the late biomarker group. Associations of early and late Th‐2 biomarkers with subsequent FEV1 decline rates were analyzed using multivariable linear regression controlling for demographics, smoking status, and other potential confounders.ResultsIn WTC‐exposed firefighters with accelerated‐FEV1‐decline, IL‐4, IL‐13, and IL‐5 measured 1–6 months post‐9/11/2001 were associated with greater FEV1 decline ml/year between 9/11/2001 and 9/10/2020 (−2.9 ± 1.4 ml/year per IL‐4 doubling; −8.4 ± 1.2 ml/year per IL‐13 doubling; −7.9 ± 1.3 ml/year per IL‐5 doubling). Among late measured Th‐2 biomarkers, only IL‐4 was associated with subsequent FEV1 decline rate (−4.0 ± 1.6 ml/year per IL‐4 doubling).ConclusionsIn WTC‐exposed firefighters with accelerated‐FEV1‐decline, elevated serum IL‐4 measured both 1–6 months and 12–13 years after 9/11 is associated with greater FEV1 decline/year. Drugs targeting the IL‐4 pathway may improve lung function in this high‐risk subgroup.
Zellpermeable Nanobodys ermöglichen Zwei‐Farben‐Superauflösungsmikroskopie in lebenden, nicht transfizierten Zellen

Published: July 2021

AbstractDie Superauflösungsmikroskopie in lebenden Zellen ist durch die Verfügbarkeit kleiner Molekülsonden, die nur gegen wenige Targets und genetisch kodierte Tags existieren, eingeschränkt. Hier erweitern wir die Anwendbarkeit von STED mithilfe zellgängiger, stark fluoreszierender Nanobodys für das intrazelluläre Targeting. Um helle Fluoreszenzsignale bei niedriger Konzentration zu gewährleisten, nutzten wir intramolekulare Photostabilisierung, indem wir einen Fluorophor zusammen mit dem Photostabilisator Trolox mittels EPL an den Nanobodys ligierten. Zudem sind diese semi‐synthetischen Nanobodys mit einem spaltbaren, zellpenetrierenden Peptid für ein effizientes Eindringen in die Zelle ausgestattet. Dadurch können wir sowohl GFP und mCherry als auch zwei endogene Zielmoleküle, die nuklearen Lamine und das DNA‐Replikations‐ und Reparaturprotein PCNA, mittels superauflösender Bildgebung visualisieren. Wir haben zudem die Zellteilung und DNA‐Replikation mittels konfokaler oder STED‐Mikroskopie überwacht und damit den Nutzen dieser Werkzeuge für die Funktionsanalyse demonstriert.

Published: July 2021

AbstractThe formation of aryl‐alkyl ether bonds through cross coupling of alcohols with aryl halides represents a useful strategic departure from classical SN2 methods. Numerous tactics relying on Pd‐, Cu‐, and Ni‐based catalytic systems have emerged over the past several years. Herein we disclose a Ni‐catalyzed electrochemically driven protocol to achieve this useful transformation with a broad substrate scope in an operationally simple way. This electrochemical method does not require strong base, exogenous expensive transition metal catalysts (e.g., Ir, Ru), and can easily be scaled up in either a batch or flow setting. Interestingly, e‐etherification exhibits an enhanced substrate scope over the mechanistically related photochemical variant as it tolerates tertiary amine functional groups in the alcohol nucleophile.

Published: July 2021

AbstractDisilenes with differently coordinated silicon atoms are not known. Here, we have shown the high yield synthesis of a range of disilenes (2–4 and 6) upon reaction of a hypersilyl silylene PhC(NtBu)2SiSi(SiMe3)3 (1) with aliphatic chlorophosphines. The most striking characteristic of these disilenes is the presence of two differently coordinated Si atoms (one is three‐coordinated, the other four‐coordinated). The analogous reaction with Ph2PCl did not afford the desired disilene, but, surprisingly, led to the first tetraphosphinosilane (8). DFT calculations were performed to understand the bonding in disilenes and differences in reactivity of the complexes.

Published: July 2021

AbstractWS2 nanosheets hold great promise for a variety of applications yet faces a grand challenge in terms of large‐scale synthesis. We report a reliable, scalable, and high‐yield (>93 %) synthetic strategy to fabricate WS2 nanosheets, which exhibit highly desirable electrocatalytic properties toward both the alkaline sulfion (S2−) oxidation reaction (SOR) and the acidic hydrogen evolution reaction (HER). The findings prompted us to develop a hybrid alkali‐acid electrochemical cell with the WS2 nanosheets as bifunctional electrode catalysts of alkaline anodic SOR and acidic cathodic HER. The proof‐of‐concept device holds promise for self‐power or low‐electricity electrolytic H2 generation and environmentally friendly recycling of sulfion with enhanced electron utilization efficiency.

AbstractReversible switching between the closed cyclic dimeric assembly [Cu2(1)2]2+ (OFF state) and the extended dimeric homoleptic complex [FeCu2(1)2]4+ (ON State) by addition/removal of Fe2+ triggered catalysis of a double‐click reaction and high yield preparation of [2]rotaxanes. Mechanistic and computational studies provide valuable general insight for double‐click strategies by revealing cooperative effects in the second cycloaddition step due to a distance‐tolerant preorganization of the first‐click product by the two copper(I)‐loaded phenanthroline subunits of [FeCu2(1)2]4+.
Effect of graphene oxide on the pH‐responsive drug release from supramolecular hydrogels
Authors: Olate‐Moya Felipe , Palza Humberto 
Published: July 2021

AbstractPolypseudorotaxane (PPR) hydrogels formed by inclusion complexes between poly(ethylene glycol) (PEG) and α‐cyclodextrin (α‐CD) are highlighted as promising biomaterial for drug delivery. Here, we report a novel injectable PPR hydrogel containing graphene oxide (GO) for pH‐responsive controlled release of doxorubicin hydrochloride (DOX). Our results showed that the gelation rates of the PEG/α‐CD supramolecular structures could be tailored depending on the reagent concentrations. The formation of PEG/α‐CD inclusion complexes was confirmed by TEM and XRD, the latter further confirming that GO restricts their formation. The supramolecular hydrogels were easily loaded with DOX by simple addition into the PEG solution before the complex formation with the α‐CD solution. Noteworthy, disruption of ionic interactions between DOX and GO in the nanocomposite at pH = 5.5 resulted in higher DOX release than under physiological conditions (pH = 7.4). This pH dependence was barely observed in pure PPR hydrogel. These findings introduce DOX‐loaded supramolecular hydrogels nanocomposites as promising carriers for pH‐responsive and therefore localized, drug delivery systems.
Physico‐mechanical properties of poly (vinyl alcohol), poly (vinyl alcohol)/boric acid, and poly (vinyl alcohol) nanocomposites incorporated with amino‐functionalized and pristine halloysite nanotubes films

Published: July 2021

AbstractEco‐friendly poly(vinyl alcohol) (PVA), PVA/boric acid, PVA/halloysite nanotubes (HNTs), and PVA/amino‐functionalized HNTs (APTES‐HNTs) films were fabricated by a solution casting technique. The samples were characterized by fourier transform infrared, X‐ray diffraction, differential scanning calorimetry, scanning electron microscope, and energy‐dispersive spectroscopy. The characterization results proved the chemical and physical interactions between the PVA and different additives. The viscoelastic behavior of the films was evaluated by DMA and creep analysis. The storage modulus, loss factor, and both αα and ββ transitions affected by APTES‐HNTs as a potential filler to form effective cross‐links. APTES‐HNTs existence enhanced creep‐recovery beyond expectations. Tensile and impact strength were measured to understand samples' mechanical stability. PVA/APTES‐HNTs and PVA/boric acid showed more yield behavior after the elastic limit. Furthermore, the subsequent rupture and impact strength were increased significantly compared with neat PVA and PVA/HNTs. The viscoelastic and mechanical behaviors were linked to each other by the area under Tanδ curve and the work of rupture and impact strength, which their linear correlation coefficient is statistically significant at 95% confidence limits. It seems that the presence of APTES‐HNTs provides new cross‐links, which altered (improved) the physico‐mechanical properties of PVA, offering a bionanocomposite suitable for further applications. From the literature, possible explanations are provided for these observations.

Published: July 2021

AbstractThe effect on the thermal conductivity and esthetic quality of acrylic denture base resins due to the addition of surface‐carboxylated nanodiamonds (NDs) was evaluated using direct heat flux measurement and spectrophotometric measurement, respectively. The addition of NDs to the denture resin improved its thermal conductivity, which was highly depended on the ND content. The thermal conductivity increased significantly upon the addition of a small amount of NDs, followed by a gradual decrease with increasing ND content. The influence of the ND content on the thermal conductivity of the ND‐impregnated resins was explained via experimental results and the theory of phonon scattering. Furthermore, changes in the appearance of the denture base resins caused by ND impregnation were observed to assess their esthetic qualities. The color changes in the resins with low ND contents were found to be minor. Therefore, the improved thermal conductivity and the retention of appearance of the resin can be simultaneously achieved by the addition of a small amount of NDs.
