AbstractAlthough understanding filament formation in oxide‐based memristive devices by theory has emerged, there are still fundamental unanswered questions. Importantly, for practical application of thin films the material in its amorphous state is to be considered, but mostly lacking so far, and details on sub‐stoichiometry are also scarce. To gain insight into the optical and electronic properties of sub‐stoichiometric amorphous tantalum oxide (TaOx), the electron energy loss spectrum (EELS) of model systems is characterized theoretically and electron transport characteristics are analyzed in detail. Calculated blue‐shifts by increasing sub‐stoichiometry explained the measurements, potentially suggesting estimation of oxygen vacancy concentrations through EEL spectra. Electron transport results based on TaOx material models validated by EELS measurements show that oxygen vacancy filamentary paths are initiated at low bias upon increasing sub‐stoichiometry yet noting an interplay with the local amorphous structure. Contact resistances at interfaces of the TaOx switching layer and a tantalum scavenging layer or titanium nitride electrode are quantified, indicating the possibility for either oxygen vacancy‐ or metal cluster‐based conduction mechanisms at the interface. The computational work, combined with experimental characterization for validation, provides a basis for investigating effects of sub‐stoichiometry on filament formation in TaOx thin film memristive devices.

AbstractFollowing the introduction of tyrosine kinase inhibitors (TKI), the number of patients undergoing allogeneic hematopoietic cell transplantation (allo‐HCT) for chronic phase (CP) chronic myeloid leukemia (CML) has dramatically decreased. Imatinib was the first TKI introduced to the clinical arena, predominantly utilized in the first line setting. In cases of insufficient response, resistance, or intolerance, CML patients can subsequently be treated with either a second or third generation TKI. Between 2006 and 2016, we analyzed the impact of the use of 1, 2, or 3 TKI prior to allo‐HCT for CP CML in 904 patients. A total of 323‐, 371‐, and 210 patients had 1, 2, or 3 TKI prior to transplant, respectively; imatinib (n = 778), dasatinib (n = 508), nilotinib (n = 353), bosutinib (n = 12), and ponatinib (n = 44). The majority had imatinib as first TKI (n = 747, 96%). Transplants were performed in CP1, n = 549, CP2, n = 306, and CP3, n = 49. With a median follow‐up of 52 months, 5‐year OS for the entire population was 64.4% (95% CI 60.9–67.9%), PFS 50% (95% CI 46.3–53.7%), RI 28.7% (95% CI 25.4–32.0%), and NRM 21.3% (95% CI 18.3–24.2%). No difference in OS, PFS, RI, or NRM was evident related to the number of TKI prior to allo‐HCT or to the type of TKI (p = ns). Significant factors influencing OS and PFS were > CP1 versus CP1 and Karnofsky performance (KPS) score > 80 versus ≤80, highlighting CP1 patients undergoing allo‐HCT have improved survival compared to >CP1 and the importance of careful allo‐HCT candidate selection.

AbstractHerein, a route to produce highly electrically conductive doped hydroxymethyl functionalized poly(3,4‐ethylenedioxythiophene) (PEDOT) films, termed PEDOT(OH) with metal‐like charge transport properties using a fully solution processable precursor polymer is reported. This is achieved via an ester‐functionalized PEDOT derivative [PEDOT(EHE)] that is soluble in a range of solvents with excellent film‐forming ability. PEDOT(EHE) demonstrates moderate electrical conductivities of 20–60 S cm−1 and hopping‐like (i.e., thermally activated) transport when doped with ferric tosylate (FeTos3). Upon basic hydrolysis of PEDOT(EHE) films, the electrically insulative side chains are cleaved and washed from the polymer film, leaving a densified film of PEDOT(OH). These films, when optimally doped, reach electrical conductivities of ≈1200 S cm−1 and demonstrate metal‐like (i.e., thermally deactivated and band‐like) transport properties and high stability at comparable doping levels.

AbstractMultivalent batteries show promising prospects for next‐generation sustainable energy storage applications. Herein, we report a polytriphenylamine (PTPAn) composite cathode capable of highly reversible storage of tetrakis(hexafluoroisopropyloxy) borate [B(hfip)4] anions in both Magnesium (Mg) and calcium (Ca) battery systems. Spectroscopic and computational studies reveal the redox reaction mechanism of the PTPAn cathode material. The Mg and Ca cells exhibit a cell voltage >3 V, a high‐power density of ∼∼3000 W kg−1 and a high‐energy density of ∼∼300 Wh kg−1, respectively. Moreover, the combination of the PTPAn cathode with a calcium‐tin (Ca−Sn) alloy anode could enable a long battery‐life of 3000 cycles with a capacity retention of 60 %. The anion storage chemistry associated with dual‐ion electrochemical concept demonstrates a new feasible pathway towards high‐performance divalent ion batteries.

AbstractPrecisely tailoring the distance between adjacent metal sites to match adsorption configurations of key species for the targeted reaction pathway is a great challenge in heterogeneous catalysis. Here, we report a proof‐of‐concept study on the atomically sites‐tailored pathway in Pd‐catalyzed acetylene hydrogenation, i.e., increasing the distance of adjacent Pd atoms (dPd‐a‐Pd) for configuration matching in acetylene semi‐hydrogenation against coupling.dPd‐a‐Pdis identified as a structural descriptor for describing the competitiveness for reaction pathways, and the increaseddPd‐a‐Pdprefers the semi‐hydrogenation pathway due to simultaneously promoted C2H4desorption and the destabilized transition state of the C2H3* coupling. Spectroscopic, kinetics and electronic structure studies reveal that increasingdPd‐a‐Pdto 3.31 Å delivers superior selectivity and stability due to energy matching and appropriate hybridization of Pd 4d with In 2s and, especially, 2p orbitals.
Effect of crumb rubber addition on the deformation and fracture behavior of ductile epoxy matrix
Authors: Tiwari Sudhendu N. , Agnihotri Prabhat K. 
Published: October 2022

AbstractA strategy is demonstrated to utilize the waste crumb rubber in ductile epoxy for low‐strength structural applications. The crosslink density is reduced to improve the ductility of epoxy by increasing the hardener concentration more than its stoichiometric composition. The ductile epoxy (Ep) is blended with 5, 10, and 20 wt% of crumb rubber particles. The rubber/epoxy (EpR) composites are characterized through quasi‐static and dynamic testing to quantify the effect of crumb rubber addition in a ductile epoxy matrix. Quasi‐static compression results show that energy absorption is enhanced after adding 5–10 wt% of crumb rubber in epoxy. Furthermore, it is found that crumb rubber modification markedly increased the energy of fracture. Crumb rubber inclusion also improves the storage modulus () and glass transition temperature (Tg) of Ep. While crumb rubber particles do not enhance the compressive response of Ep under high strain rate loading, their addition significantly reduces the intensity of the transmitted wave. Subsequently, it suggests dual advantages, that is, Ep can be effectively toughened with 5–10 wt% of crumb rubber, and the resulting EpR may be used as an interlayer/backing plate in impact‐resistant panels to mitigate adverse effects of the transmitted stress waves.

AbstractReX2 (X = S, Se) remains a copious source of controversies and unanswered questions due to its widely contrasting experimental and theoretical results. With the help of comparative first‐principles electronic structure and phonon calculations, the correct structures for both systems are established, which minimize the apparent divergence of different experimental results. It is demonstrated that ReS2 and ReSe2 are neither iso‐structural nor iso‐electronic. The contributions of the in‐plane and out‐of‐plane orbitals at the band‐edges of the bulk and monolayers are coordinated with their anisotropic optical response. Under moderately high pressure, both of these systems are observed to undergo a semiconductor to metal transition. With the help of a combined full‐potential density functional theory and multiplet ligand field theory (DFT+MLFT) approach, the X‐ray spectral properties of these two systems are analyzed in the light of their intricate differences of optimized structures and electronic correlations.

AbstractThis study examines trends in open access article processing charges (APCs) from 2011 to 2021, building on a 2011 study by Solomon and Björk. Two methods are employed, a modified replica and a status update of the 2011 journals. Data are drawn from multiple sources and datasets are available as open data. Most journals do not charge APCs; this has not changed. The global average per‐journal APC increased slightly, from 906 to 958 USD, while the per‐article average increased from 904 to 1,626 USD, indicating that authors choose to publish in more expensive journals. Publisher size, type, impact metrics and subject affect charging tendencies, average APC, and pricing trends. Half the journals from the 2011 sample are no longer listed in DOAJ in 2021, due to ceased publication or publisher de‐listing. Conclusions include a caution about the potential of the APC model to increase costs beyond inflation. The university sector may be the most promising approach to economically sustainable no‐fee OA journals. Universities publish many OA journals, nearly half of OA articles, tend not to charge APCs and when APCs are charged, the prices are very low on average.

Published: October 2022

AbstractBackgroundMonoclonal antibodies (mAbs) are leading types of ‘blockbuster’ biotherapeutics worldwide; they have been successfully used to treat various cancers and chronic inflammatory and autoimmune diseases. Biotherapeutics process development and manufacturing are complicated due to lack of understanding the factors that impact cell productivity and product quality attributes. Understanding complex interactions between cells, media, and process parameters on the molecular level is essential to bring biomanufacturing to the next level. This can be achieved by analyzing cell culture metabolic levels connected to vital process parameters like viable cell density (VCD). However, VCD and metabolic profiles are dynamic parameters and inherently correlated with time, leading to a significant correlation without actual causality. Many time‐series methods deal with such issues. However, with metabolic profiling, the number of measured variables vastly exceeds the number of experiments, making most of existing methods ill‐suited and hard to interpret.Methods and Major ResultsHere we propose an alternative workflow using hierarchical dimension reduction to visualize and interpret the relation between evolution of metabolic profiles and dynamic process parameters. The first step of proposed method is focused on finding predictive relation between metabolic profiles and process parameter at all time points using OPLS regression. For each time point, the p(corr) obtained from OPLS model is considered as a differential metabogram and is further assessed using principal components analysis (PCA).ConclusionsCompared to traditional batch modeling, applying proposed methodology on metabolic data from Chinese Hamster Ovary (CHO) antibody production characterized the dynamic relation between metabolic profiles and critical process parameters.
Intraosseous administration into the skull: Potential blood–brain barrier bypassing route for brain drug delivery
Authors: Kang Ji Hee , Ko Young Tag 
Published: October 2022

AbstractProgress in treating central nervous system (CNS) disorders is retarded owing to a limited understanding of brain disease pathology. Additionally, the blood–brain barrier (BBB) limits molecular entry into the brain. Many approaches for brain drug delivery to overcome the BBB, such as BBB permeability enhancement, transient BBB disruption, and direct surgical administration have been explored with limited success. Recent research has shown that direct vascular channels exist between the skull bone marrow and the meninges, allowing myeloid and lymphoid cells to migrate. We hypothesized that these direct channels may also allow brain drug delivery from the skull bone marrow to the brain. In this study, for the first time we propose intraosseous administration of drugs into the skull (intracalvariosseous [ICO]) as a novel approach for brain drug delivery via BBB bypassing routes. We tested the feasibility of the approach by applying nine representative compounds over thinned mouse skulls to simulate ICO and measuring the compound entry level in the brain compared to that after systemic administration. Surprisingly, we found that the skull is not completely impermeable to drug penetration into the brain and the tested compounds reached the brain tissue several tens‐to‐hundred times higher by ICO than systemic application. These findings suggest a role for the BBB bypassing route from skull to brain, apart from the systemic route, in the drug entry into the brain after ICO. This approach should be applicable to other CNS drugs and even BBB impermeable drugs. Overall ICO provides an innovative and advantageous pathway for effective treatment of brain diseases.

Authors: Geneci Ferhat , Ocak Mert 
Published: October 2022

AbstractThis study aimed to determine sinus tympani, subtympanic sinus (STS), facial sinus (FS) morphologies, and type distributions. Type distributions were based on their relations with the facial nerve (FN). A total of 20 right and 20 left temporal dry bones without physical deformation were scanned with a MicroCT device. All measurements were made using MicroCT programs from sections in the axial plane. For the FS, the average depth was measured as 3.485 mm without any classification, and 29 of the 40 bones had Type C radiological morphology. The mean depth for all sinus tympanicus was 2.646 mm, and 22 of the 40 bones had Type B morphology. For the STS, 29 out of 40 samples had no contact with the FN; regardless of the classification, the average depth was measured as 2.376 mm. We reveal the depths of the tympanic cavities and their relationship with the FN. The results of this study may benefit clinicians performing retrotympanum surgeries.
Minimally invasive tunneling of a de‐epithelialized connective tissue graft to improve gingival phenotype of lingual recession defects: A case report
Authors: Danskin Yoonah , Chu Stephanie , Simmonds Trevor 
Published: October 2022

AbstractBackgroundThis case report describes a minimally invasive technique to increase the functional resistance of mandibular anterior lingual recession defects to inflammation. There are only a few case reports that describe the soft tissue augmentation of lingual gingival recession, of which none describe a tunneling technique without coronal advancement of the flap to treat a long span of multiple recession defects. Soft tissue augmentation of lingual recession defects is challenging due to the proximity to the tongue, frenum, vital structures, pre‐existing thin phenotype, and limited access during surgery.Methods and ResultsA 30‐year‐old male was referred for the treatment of gingival recession on the lingual surfaces of teeth #22–27, with a diagnosis of recession type 2 (RT2). Mucogingival surgery included the preparation of the recipient site with a tunneling protocol, where apical muscular attachment was left undisturbed to isolate the flap from the movement of the tongue during normal function. As the goal was to not coronally advance the tunneled flap, the interdental papillae were not elevated and left intact, further optimizing blood supply. A free gingival graft was harvested, de‐epithelialized extra‐orally, and the resulting connective tissue graft (CTG) was fed through the tunnel and stabilized with sling sutures. Partial root coverage was achieved ranging from 50% to 90% at 4 months, consistent with the initial diagnosis of RT2. There was also a visually appreciable increase in gingival thickness and in the vestibular depth.ConclusionA de‐epithelialized CTG via tunneling without disturbing the deeper muscular attachment is a conservative method to improve phenotype of lingual recession defects.Key pointsWhy is this case new information?

There are only a few case reports that describe soft tissue augmentation of lingual recession defects, of which none describe a tunneling technique without coronal advancement of the flap to treat a long span of multiple recession defects. This case report introduces a minimally invasive technique to increase the functional resistance of mandibular anterior lingual recession defects to plaque and calculus.
What are the keys to successful management of this case?

Control of gingival inflammation before and after surgery, with regular maintenance visits and oral hygiene instructions.
Precise tunneling, leaving deeper muscular attachment on the floor of the mouth undisturbed.
Connective tissue graft of even thickness that is fibrous in quality.
What are the primary limitations to success in this case?

A shallow lingual vestibule will not allow the clinician to leave deeper muscular attachment apical to tunneling undisturbed.

AbstractPreparations of Helicteres sacarolha (Malvaceae) leaves and roots are used in the form of decoction, infusion or maceration, to treat gastrointestinal disturbances, among others. Studies supporting some of its ethnomedicinal uses are still incipient. The present study aimed to investigate it potential effect on chronic ulcer, ulcerative colitis and possible prokinetic activities as part of its mechanism of action. The powdered leaves of Helicteres sacarolha (HEHs) was prepared by maceration in 70 % hydroethanolic solution. Its qualitative phytochemical constituents were investigated by direct flow injection analysis coupled to atmospheric pressure chemical ionization ion trap tandem mass spectrometry (FIA‐APCI‐IT‐MSn). The gastric ulcer healing effect was evaluated in acetic acid induced chronic ulcer in mice and the lesions were evaluated, including analysis of blood plasma cytokine levels. The prokinetic properties (gastric emptying and intestinal transit) were carried out in mice. Potential anti‐ulcerative colitis activity was evaluated in rats using 2,4,6‐trinitrobenzenesulfonic acid (5 % TNBS) ‐induced colitis. All animal experiments were carried out at the doses of 20, 50 and 250 mg/kg (p.o.). Eight compounds were putatively identified, specifically lariciresinol, and its derivatives, kaempferol derivatives and Tricin‐O‐Glc. The extract promoted increased gastric ulcer healing at all doses tested. Modulation of the cytokines involved inhibition of some key pro‐inflammatory cytokines with maximum effect on IL‐1β (70 %, 50 mg/kg, p<0.05), TNF‐α (79 %, 20 mg/kg, p<0.01), and in the anti‐inflammatory cytokines, namely IL‐10 (57 %, 50 mg/kg, p<0.05) and IL‐17 (79 %, only at 50 mg/kg, p<0.05). Histological findings demonstrated a mitigated inflammatory activity, and tissues undergoing regeneration. HEHs treatment caused delayed gastric emptying, and increased intestinal transit, but had no effect in the experimentally induced ulcerative colitis. We report for the first time putatively the presence of Lariciresinol and tricin derivatives from the hydroethanolic leaves extract of H. sacarolha. Its possible mechanism of actions of gastric ulcer healing involves cytokines modulation, mitigation of inflammatory response and tissue regeneration and provoked opposing effect in the gastrointestinal system. The present study demonstrates the therapeutic potential of H. sacarolha leaves used in Brazilian ethnomedicine in the treatment of chronic gastric ulcer.
