This study investigates the sensitive region and safe operation voltage of single-event burnout (SEB) in lateral depletion-mode Ga2O3 MOSFET devices via technology computer aided design simulation. Based on the distribution of the electric field, carrier concentration, and electron current density when SEB occurs, the radiation damage mechanism of SEB is proposed. The mechanism of SEB in Ga2O3 MOSFET was revealed to be the result of a unique structure without a PN junction within it, which possesses gate control ability and exerts a significant influence on the conduction of the depletion region.

A thermophilic strain of Laceyella sacchari designated as FBKL4.014 was isolated from high-temperature Moutai-flavor Daqu, and its whole genome was sequenced. The results showed that the full genomic length of L. sacchari FBKL4.014 was 3.35 Mb, with a GC content of 48.67%. The sequencing depth was 433 ×, and a total of 3 328 protein-coding genes were predicted. Strain FBKL4.014 had the potential for complete carbohydrate and amino acid metabolism, and it was further inferred that the strain may have the potential to biosynthesize tetramethylpyrazine. This study provides genetic data for understanding the mechanism for the production of flavor substances in Maotai-flavor baijiu by Thermoactinomycetaceae metabolism, and also provides a reference for further research on the discovery of unknown functional genes of this strain and its genetic modification.

Inflammation is highlighted as an initial factor that helps orchestrate liver reconstitution. However, the precise mechanisms controlling inflammation during liver reconstitution have not been fully elucidated. In this study, a clear immune response is demonstrated during hepatic reconstitution. Inhibition of the hepatic inflammatory response retards liver regeneration. During this process, Ccl2 is primarily produced by type 1 innate lymphoid cells (ILC1s), and ILC1‐derived Ccl2 recruits peripheral ILC1s and regulatory T cells (Tregs) to the liver. Deletion of Ccl2 or Tregs exacerbates hepatic injury and inflammatory cytokine release, accelerating liver proliferation and regeneration. The adoption of Tregs and IL‐10 injection reversed these effects on hepatocyte regenerative proliferation. Additionally, Treg‐derived IL‐10 can directly induce macrophage polarization from M1 to M2, which alleviated macrophage‐secreted IL‐6 and TNF‐α and balanced the intrahepatic inflammatory milieu during liver reconstitution. This study reveals the capacity of Tregs to modulate the intrahepatic inflammatory milieu and liver reconstitution through IL‐10‐mediated macrophage polarization, providing a potential opportunity to improve hepatic inflammation and maintain homeostasis.

The synergistic effect of total ionizing dose on single event gate rupture (SEGR) was simulated in the vertical double diffusion metal oxide semiconductor device with SiO2–Si3N4 stacked gate layer. In comparison to the device with a single SiO2 gate layer, the synergistic effect was revealed to be suppressed in the device with SiO2–Si3N4 stacked layer. The mechanism is that the oxide layer is a sensitive area of the SEGR effect. Compared with the single SiO2 layer, the superposition of the additional electric field formed by the trapped holes in the sensitive area of the stacked layer leads to a decrease in the sensitivity of the synergistic effect, which is more obvious with increasing the volume of the Si3N4 layer.

Sepsis, a severe and life-threatening condition arising from a dysfunctional host response to infection, presents considerable challenges to the health care system and is characterized by high mortality rates and substantial economic costs. Exosomes have garnered attention as potential diagnostic markers because of their capacity to mirror the pathophysiological milieu of sepsis. This discourse reviews the progression of sepsis classification from Sepsis 1.0 to Sepsis 3.0, highlighting the imperative for sensitive and specific biomarkers to facilitate timely diagnosis and optimize patient outcomes. Existing biomarkers, such as procalcitonin (PCT) and C-reactive protein (CRP), exhibit certain limitations, thereby prompting the quest for more dependable diagnostic indicators. Exosomal cargoes, which encompass proteins and miRNAs, present a trove of biomarker candidates, attributable to their stability, pervasive presence, and indicative nature of the disease status. The potential of exosomal biomarkers in the identification of sepsis-induced organ damage, including cardiomyopathy, acute kidney injury, and acute lung injury, is emphasized, as they provide real-time insights into cardiac and renal impairments. Despite promising prospects, hurdles persist in the standardization of exosome extraction and the need for extensive clinical trials to validate their efficacy. The combination of biomarker development and sophisticated exosome detection techniques represents a pioneering strategy in the realm of sepsis diagnosis and management, underscoring the significance of further research and clinical validation.

The flexibility of soft open point (SOP) in spatial power regulation enhances the distribution network's (DN) integration of large‐scale renewable energy sources. However, the high cost of SOP and its limited capability for temporal power regulation impede its widespread adoption. Given the rapid expansion of 5G base stations (BSs), utilizing their energy storage to participate in DN planning and operation optimization provides a promising solution. Therefore, this paper proposes an optimal planning method of SOP in DN, considering collaborations with 5G BSs. The objective is to enhance DN's power regulation in both temporal and spatial dimensions, while minimizing the investment cost of SOP and fully utilizing the unused capacity in base station energy storage (BSES). Firstly, the flexible regulation models of SOP and 5G BS are established, with the real‐time dispatchability of BSES formulated. Then, a bi‐level optimization model is proposed, where the planning layer aims to minimize the total cost, while the operational layer aims to decrease the average voltage deviation. Additionally, an improved Shapley value method based on interactive power is developed for benefit allocation, which enhances the engagement of 5G BSs to participate in DN regulation. The effectiveness of proposed method is validated by simulation results. [ABSTRACT FROM AUTHOR]

The nucleus accumbens (NAc) is the most promising target for drug use disorder treatment. Deep brain stimulation (DBS) of NAc is effective for drug use disorder treatment. However, the mechanisms by which DBS produces its therapeutic effects remain enigmatic. Here, we define a behavioral cutoff criterion to distinguish depressive-like behaviors and nondepressivelike behaviors in mice after morphine withdrawal. We identified a basolateral amygdala (BLA) to NAc D1 medium spiny neuron (MSN) pathway that controls depressive-like behaviors after morphine withdrawal. Furthermore, the paraventricular nucleus of thalamus (PVT) to NAc D2 MSN pathway controls naloxone-induced acute withdrawal symptoms. Optogenetically induced long-term potentiation with K-opioid receptor (KOR) antagonism enhanced BLA to NAc D1 MSN signaling and also altered the excitation/inhibition balance of NAc D2 MSN signaling. We also verified that a new 50 Hz DBS protocol reversed morphine withdrawal-evoked abnormal plasticity in NAc. Importantly, this refined DBS treatment effectively alleviated naloxone-induced withdrawal symptoms and depressive-like behaviors and prevented stress-induced reinstatement. Taken together, the results demonstrated that input- and cell type-specific synaptic plasticity underlies morphine withdrawal, which may lead to novel targets for the treatment of opioid use disorder., Introduction Opioid drugs are powerful analgesics, but they are also highly addictive due to the elicitation of powerful euphoria. Opioid use disorder depends not only on its positive reinforcement effects, [...]

Hair follicle (HF) regeneration during wound healing continues to present a significant clinical challenge. Dermal papilla cell-derived exosomes (DPC-Exos) hold immense potential for inducing HF neogenesis. However, the accurate role and underlying mechanisms of DPC-Exos in HF regeneration in wound healing remain to be fully explained. This study, represents the first analysis into the effects of DPC-Exos on fibroblasts during wound healing. Our findings demonstrated that DPC-Exos could stimulate the proliferation and migration of fibroblasts, more importantly, enhance the hair-inducing capacity of fibroblasts. Fibroblasts treated with DPC-Exos were capable of inducing HF neogenesis in nude mice when combined with neonatal mice epidermal cells. In addition, DPC-Exos accelerated wound re-epithelialization and promoted HF regeneration during the healing process. Treatment with DPC-Exos led to increased expression levels of the Wnt pathway transcription factors β-catenin and Lef1 in both fibroblasts and the dermis of skin wounds. Specifically, the application of a Wnt pathway inhibitor reduced the effects of DPC-Exos on fibroblasts and wound healing. Accordingly, these results offer evidence that DPC-Exos promote HF regeneration during wound healing by enhancing the hair-inducing capacity of fibroblasts and activating the Wnt/β-catenin signaling pathway. This suggests that DPC-Exos may represent a promising therapeutic strategy for achieving regenerative wound healing. [ABSTRACT FROM AUTHOR]
