Desulfobacterota / Desulfobacteria / Desulfobacterales / Desulfolunaceae

Cells are straight or slightly curved rods which occur singly or in pairs. Gram‐stain‐negative. Endospores are not observed. Motility varies depending on the species. Anaerobic, having a respiratory and sometimes fermentative type of metabolism. Chemoorganoheterotrophs. Lactate, pyruvate, malate, and short‐chain fatty acids can serve as sole electron donors and carbon sources and are oxidized incompletely to acetate by most members of the family. One species performs complete oxidation of organic multicarbon substrates to CO
2
. Formate is used as an electron donor for growth in the presence of acetate. Sulfate is used as electron acceptor by all species and is reduced to sulfide; in addition, a few species can use FeIII‐citrate and halogenated phenols as electron acceptors. Neutrophilic; the optimal pH for growth is around 7. Mesophilic or psychrophilic; the optimal temperature range for growth is between 10 and 30°C. The major menaquinone is MK‐9 or MK‐8(H
2
). Optimal growth occurs at marine salt concentrations. Media containing reductants are optimal for growth by sulfate reduction. Organohalide reduction may occur in medium with low oxygen content (2 vol %). The family currently accommodates two genera. The type strain of the type genus was isolated from permanently cold marine sediment. Present in anoxic marine sediments and sponges.

Sequencing of nearly full‐length PCR‐amplified 16S rRNA genes, combined with earlier studies, provided the first comprehensive phylogeny of the organisms and showed that they constitute a unique, monophyletic clade within theMollicutes. These organisms are most closely related to members of the genusAcholeplasmawithin theAnaeroplasmaclade as defined by Weisburg et al. Despite decades of efforts and recent progress, sustained pure culture in cell‐free media has not yet been demonstrated for any phytoplasma. Their genome sizes have been estimated to range from 530 to 1,350 kb, and the DNA G + C content is about 23–30 mol%. The presence of a characteristic oligonucleotide sequence in the 16S rRNA gene, CAA GAY BAT KAT GTK TAG CYG GDC T, and standard codon usage indicate that phytoplasmas represent a distinct genus‐level taxon for which the name ‘CandidatusPhytoplasma’ has been adopted. At present, for any subtaxa within the provisional genus, the designation ‘Candidatus’ must still be used.DNA G + C content (mol%): 23–29.

Accuracy and efficiency of respiratory gating comparable to deep inspiration breath hold for pancreatic cancer treatment

Published: December 2020

AbstractPurposeDeep inspiration breath hold (DIBH) and respiratory gating (RG) are widely used to reduce movement of target and healthy organs caused by breathing during irradiation. We hypothesized that accuracy and efficiency comparable to DIBH can be achieved with RG for pancreas treatment.Methods and MaterialsTwenty consecutive patients with pancreatic cancer treated with DIBH (eight) or RG (twelve) volumetric modulated arc therapy during 2017–2019 were included in this study, with radiopaque markers implanted near or in the targets. Seventeen patients received 25 fractions, while the other three received 15 fractions. Only patients who could not tolerate DIBH received RG treatment. While both techniques relied on respiratory signals from external markers, internal target motions were monitored with kV X‐ray imaging during treatment. A 3‐mm external gating window was used for DIBH treatment; RG treatment was centered on end‐expiration with a duty cycle of 40%, corresponding to an external gating window of 2–3 mm. During dose delivery, kV images were automatically taken every 20◦ or 40◦ gantry rotation, from which internal markers were identified. The marker displacement from their initial positions and the residual motion amplitudes were calculated. For the analysis of treatment efficiency, the treatment time of every session was calculated from the motion management waveform files recorded at the treatment console.ResultsWithin one fraction, the displacement was 0–5 mm for DIBH and 0–6 mm for RG. The average magnitude of displacement for each patient during the entire course of treatment ranged 0–3 mm for both techniques. No statistically significant difference in displacement or residual motion was observed between the two techniques. The average treatment time was 15 min for DIBH and 17 min for RG, with no statistical significance.ConclusionsThe accuracy and efficiency were comparable between RG and DIBH treatment for pancreas irradiation. RG is a feasible alternative strategy to DIBH.

AbstractControlling the morphology of metal halide perovskite layers during processing is critical for the manufacturing of optoelectronics. Here, a strategy to control the microstructure of solution‐processed layered Ruddlesden–Popper‐phase perovskite films based on phenethylammonium lead bromide ((PEA)2PbBr4) is reported. The method relies on the addition of the organic semiconductor 2,7‐dioctyl[1]benzothieno[3,2‐b]benzothiophene (C8‐BTBT) into the perovskite formulation, where it facilitates the formation of large, near‐single‐crystalline‐quality platelet‐like (PEA)2PbBr4 domains overlaid by a ≈5‐nm‐thin C8‐BTBT layer. Transistors with (PEA)2PbBr4/C8‐BTBT channels exhibit an unexpectedly large hysteresis window between forward and return bias sweeps. Material and device analysis combined with theoretical calculations suggest that the C8‐BTBT‐rich phase acts as the hole‐transporting channel, while the quantum wells in (PEA)2PbBr4 act as the charge storage element where carriers from the channel are injected, stored, or extracted via tunneling. When tested as a non‐volatile memory, the devices exhibit a record memory window (>180 V), a high erase/write channel current ratio (104), good data retention, and high endurance (>104 cycles). The results here highlight a new memory device concept for application in large‐area electronics, while the growth technique can potentially be exploited for the development of other optoelectronic devices including solar cells, photodetectors, and light‐emitting diodes.
MnO2 Nanoflowers Induce Immunogenic Cell Death under Nutrient Deprivation: Enabling an Orchestrated Cancer Starvation‐Immunotherapy

Published: December 2020

AbstractMnO2 nanoparticles have been widely employed in cancer immunotherapy, playing a subsidiary role in assisting immunostimulatory drugs by improving their pharmacokinetics and/or creating a favorable microenvironment. Here, the stereotype of the subsidiary role of MnO2 nanoparticles in cancer immunotherapy is challenged. This study unravels an intrinsic immunomodulatory property of MnO2 nanoparticles as a unique nutrient‐responsive immunogenic cell death (ICD) inducer, capable of directly modulating immunosurveillance toward tumor cells. MnO2 nanoflowers (MNFs) constructed via a one pot self‐assembly approach selectively induce ICD to nutrient‐deprived but not nutrient‐replete cancer cells, which is confirmed by the upregulated damage associated molecular patterns in vitro and a prophylactic vaccination in vivo. The underlying mechanism of the MNFs‐mediated selective ICD induction is likely associated with the concurrently upregulated oxidative stress and autophagy. Built on their unique immunomodulatory properties, an innovative nanomaterials orchestrated cancer starvation‐immunotherapy is successfully developed, which is realized by the in situ vaccination with MNFs and vascular disrupting agents that cut off intratumoral nutrient supply, eliciting potent efficacy for suppressing local and distant tumors. These findings open up a new avenue toward biomedical applications of MnO2 materials, enabling an innovative therapeutics paradigm with great clinical significance.

Published: December 2020

AbstractRadiotherapy (RT) based on DNA damage and reactive oxygen species (ROS) generation has been clinically validated in various types of cancer. However, high dose‐dependent induced toxicity to tissues, non‐selectivity, and radioresistance greatly limit the application of RT. Herein, an oxygen‐enriched X‐ray nanoprocessor Hb@Hf‐Ce6 nanoparticle is developed for improving the therapeutic effect of RT‐radiodynamic therapy (RDT), enhancing modulation of hypoxia tumor microenvironment (TME) and promoting antitumor immune response in combination with programmed cell death protein 1 (PD‐1) immune checkpoint blockade. All functional molecules are integrated into the nanoparticle based on metal‐phenolic coordination, wherein one high‐Z radiosensitizer (hafnium, Hf) coordinated with chlorin e6 (Ce6) modified polyphenols and a promising oxygen carrier (hemoglobin, Hb) is encapsulated for modulation of oxygen balance in the hypoxia TME. Specifically, under single X‐ray irradiation, radioluminescence excited by Hf can activate photosensitizer Ce6 for ROS generation by RDT. Therefore, this combinatory strategy induces comprehensive antitumor immune response for cancer eradication and metastasis inhibition. This work presents a multifunctional metal‐phenolic nanoplatform for efficient X‐ray mediated RT‐RDT in combination with immunotherapy and may provide a new therapeutic option for cancer treatment.
Phonon–Ion Interactions: Designing Ion Mobility Based on Lattice Dynamics
Authors: Muy Sokseiha , Schlem Roman , Shao‐Horn Yang , Zeier Wolfgang G. 
Published: December 2020

AbstractThis review is focused on the influence of lattice dynamics on the ionic mobility in superionic conductors in particular solid‐state Li‐ion conductors. After a succinct review of the static view of ionic conduction, the role of polarizability as the underlying cause of lattice softness is discussed in connection with the anharmonicity and the roles of lattice dynamics on ionic conductivity as proposed in early theories in the 70's and 80's by Mahan, Zeller, Rice and Roth are reviewed with the emphasis on various proposed correlations between Debye and Einstein frequency as well as other specific vibrational modes with the activation energy. The role of lattice dynamics on the correlation between the pre‐exponential factor and activation energy, i.e. the Meyer‐Neldel rule is also presented with emphasis on the entropy of migration and its dependence on the vibrational spectrum of the lattice. Moreover, a recent computational high‐throughput screening based on the average vibrational frequency is also discussed to illustrate the application of lattice dynamics descriptors to design new lithium conductors. Finally, several open questions regarding the fundamental understanding of the role of lattice dynamics and new strategies to tune ionic conductivity based on these concepts are presented.

AbstractAqueous rechargeable Zn–MnOx batteries are very attractive due to their low‐cost and high energy density. However, Mn(III) disproportionation and Jahn–Teller distortion can induce Mn(II) dissolution and irreversible phase changes, greatly deteriorating the cycling life. Herein, a multi‐valence cobalt‐doped Mn3O4 (Co‐Mn3O4) with high capacity and reversibility, which lies in the multiple roles of the various states of doped cobalt, is reported. The Co2+ doping between the phase change product δ‐MnO2 layer acts as a “structural pillar,” and the Co4+ in the layer can increase the conductivity of Mn4+ and hold the high specific capacity. More importantly, Co ion (Co2+, Co3+) doping can effectively inhibit the Jahn–Teller effect in discharge products and promote ion diffusion. Using X‐ray absorption spectra results and density functional theory modelling, the multiple roles of doped cobalt are verified. Specifically, the Co‐Mn3O4 cathode shows high specific capacity of 362 mAh g–1 and energy density of 463.1 Wh kg–1 at 100 mA g–1. After 1100 cycles at 2.0 A g–1, the capacity retention rate reaches 80%. This work brings a new idea and approach to the design of highly reversible Mn‐based oxides cathode materials for Zn‐ion batteries.
Molecular dynamics simulations of enantiomeric separations as an interfacial process in HPLC
Authors: Jameson Cynthia J. , Wang Xiaoyu , Murad Sohail 
Published: December 2020

AbstractSince chromatographic separation is a dynamic process, with the interactions between the drug and the chiral stationary phase mediated by the solvent, no single interacting structure, such as could be found by minimizing the energy, could possibly describe and account for the ratio of residence times in the chromatographic column for the enantiomeric pair. We describe the use of explicit‐solvent fully atomistic molecular dynamics simulations, permitting all the interactions between the atoms constituting the chiral stationary phase, solvent molecules and the drug molecule. This allows us to better understand the molecular dynamic chiral recognition that provides the discrimination, which results in the separation of enantiomers by high performance liquid chromatography. It also provides a means of predicting, for a given set of conditions, which enantiomer elutes first and an estimate of the expected separation factor. In this review, we consider the use of molecular dynamics toward this understanding and prediction.
