    Abstract The tribovoltaic devices have demonstrated an enormous current density output from friction. This has attracted attention, and thus, the tribovoltaic device research is expected to grow rapidly, providing mechanical energy harvesting from human motion or mechanical vibrations to power the microdevices. Herein, we are demonstrating the novel tribovoltaic device based on the W/WO₃ Schottky junction enabled by high-energy electrons as in hot-carrier photovoltaic devices. The hot carrier injection from the metal to the semiconductor has been well demonstrated before in light-driven devices but not demonstrated for tribovoltaic devices. Friction-caused electronic excitations on the W needle provide energy for electrons to overcome the Schottky barrier and generate the unbiased current density up to 1270 A m–². The amorphous WO₃ derived from magnetron sputtering shows high durability and reliability of the tribovoltaic device.

    Abstract Type 2 immune responses form a critical defence against enteric worm infections. In recent years, mouse models have revealed shared and unique functions for group 2 innate lymphoid cells and T helper 2 cells in type 2 immune response to intestinal helminths. Both cell types use similar innate effector functions at the site of infection, whereas each population has distinct roles during different stages of infection. In this Perspective, we review the underlying mechanisms used by group 2 innate lymphoid cells and T helper 2 cells to cooperate with each other and suggest an overarching model of the interplay between these cell types over the course of a helminth infection.

    Abstract Innate lymphoid cells (ILCs) can promote host defense, chronic inflammation, or tissue protection and are regulated by cytokines and neuropeptides. However, their regulation by diet and microbiota-derived signals remains unclear. We show that an inulin fiber diet promotes Tph1-expressing inflammatory ILC2s (ILC2INFLAM) in the colon, which produce IL-5 but not tissue-protective amphiregulin (AREG), resulting in the accumulation of eosinophils. This exacerbates inflammation in a murine model of intestinal damage and inflammation in an ILC2- and eosinophil-dependent manner. Mechanistically, the inulin fiber diet elevated microbiota-derived bile acids, including cholic acid (CA) that induced expression of ILC2-activating IL-33. In IBD patients, bile acids, their receptor farnesoid X receptor (FXR), IL-33, and eosinophils were all upregulated compared with controls, implicating this diet-microbiota-ILC2 axis in human IBD pathogenesis. Together, these data reveal that dietary fiber-induced changes in microbial metabolites operate as a rheostat that governs protective versus pathologic ILC2 responses with relevance to precision nutrition for inflammatory diseases.

    Abstract The abundance of innate and adaptive immune cells that reside together with trillions of beneficial commensal microorganisms in the mammalian gastrointestinal tract requires barrier and regulatory mechanisms that conserve host-microbial interactions and tissue homeostasis. This homeostasis depends on the diverse functions of intestinal epithelial cells (IECs), which include the physical segregation of commensal bacteria and the integration of microbial signals. Hence, IECs are crucial mediators of intestinal homeostasis that enable the establishment of an immunological environment permissive to colonization by commensal bacteria. In this Review, we provide a comprehensive overview of how IECs maintain host-commensal microbial relationships and immune cell homeostasis in the intestine.

    Abstract Non-enzymatic dynamic kinetic resolution (DKR) of secondary alcohols by enantioselective acylation using an isothiourea-derived HyperBTM catalyst and racemization of slowly reacting alcohol by Bäckvall’s ruthenium complex is reported. The DKR approach features high enantioselectivities (up to 99:1), employs easy-to-handle crystalline 4-nitrophenyl isobutyrate as the acylating reagent, and proceeds at room temperature and under an ambient atmosphere. The stereoinduction model featuring cation−π system interactions between the acylated HyperBTM catalyst and π electrons of an alcohol aryl subunit has been elaborated by DFT calculations.

    Abstract Group 2 innate lymphoid cells (ILC2s) reside in multiple tissues, including lymphoid organs and barrier surfaces, and secrete type 2 cytokines including interleukin-5 (IL-5), IL-9, and IL-13. These cells participate in multiple physiological processes including allergic inflammation, tissue repair, metabolic homeostasis, and host defense against helminth infections. Recent studies indicate that neurotransmitters and neuropeptides can play an important role in regulating ILC2 responses; however, the mechanisms that underlie these processes in vivo remain incompletely defined. Here, we identify that activated ILC2s up-regulate choline acetyltransferase (ChAT)-the enzyme responsible for the biosynthesis of acetylcholine (ACh)-after infection with the helminth parasite

    Abstract Background: A posterior circulation infarction is caused by a vertebral artery (VA) lesion (stenosis or occlusion). The purpose of this study is to assess early and long-term outcomes after open surgery for a VA lesion at the origin.
    Methods: In a retrospective study conducted from January 1, 2000 through March 31, 2020 in a single center, patients were treated with vertebral artery to carotid artery transposition (VCT).
    Results: A total of 28 patients, with a mean age of 65.29 ± 9.81 years (range 45-84), were screened, including 22 patients with VA stenosis and 6 patients with VA occlusion. The complication rate was 21.4% (n = 6), including Horner syndrome (n = 2), lymphocele (n = 1), respiratory failure (n = 1), embolism of a subclavian artery stenosis (n = 1), and vocal cord paralysis (n = 1). The 30-day mortality rate was 0%. Primary patency was 100%. Overall, improvement in symptoms was 85.7% (n = 24) after surgery and 96.4% after 30 days. In the long-term results, primary patency was 100%, and the cumulative patency rate after 60 months was 85.7%, with 1 occlusion of the VA. Cumulative survival rates were 94%, 87%, 69%, and 59% after 12, 24, 60, and 72 months (n = 5). One of the 3 patients died after 60 months because of VA occlusion and posterior circulation infarction.
    Conclusions: VCT is a safe, effective, and durable procedure. It provides good stroke protection, symptomatic relief, and perioperative risk at acceptable levels, in experienced hands.
