In this study, S-deficient MoS was prepared using proton irradiation and then applied as sensing materials for the detection of NO gas. First, bulk MoS was treated by ultrasonics to produce 2D nanosheets of MoS, which were subsequently bombarded by a flux of high-energy protons, resulting in the appearance of structural defects throughout MoS. The proton fluxes were adjusted to different densities of 1 × 10, 1 × 10, 1 × 10, and 1 × 10 ions/cm.

In this work, a series of Sm singly and Sm/Eu co-doped CeO cubic phosphors was successfully synthesized by solution combustion followed by heat treatment at 800 °C in air. The crystal structure, morphology, chemical element composition, and luminescence properties of the obtained phosphors were investigated using X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and photoluminescence analysis.

It is thus urgent to examine their perceptions of the potential risks, their coping strategies, and the factors influencing their adaptation decisions in agriculture production. By exploring adaptation measures of the Xo Dang and Co Tu EMFs in Quang Nam province, Central Vietnam, the study results reveal that the EMFs are increasingly conscious of local climate shocks in the recent decade; as a result, they have applied multiple specific strategies in agriculture production to mitigate risks.

The results of phylogenetic analysis show that DuPV-BAFU evolved from a goose lineage and duck parvoviruses rather than from Muscovy duck parvoviruses. In the genetic lineages, DuPVs were identified from the DuPV samples analyzed, and DuPV-BAFU was found to be closely clustered with two known goose origin parvoviruses (GPVa2006 and GPV1995) and a duck GPVs.

The structural features including the electronic structure lattice constant (a), shape, total energy (E) per cell, and link length (r), are measured via band gap (E) prediction with the package of country density (PDOS) and total country density (DOS) of material studio software. The results obtained showed that the link angle and the link length between atoms were not changed significantly while the E was decreased from E = - 1904 eV (in P1) to E = - 2548 eV (in P2) when replacing O with S; and the E of P3 was decreased from E = - 3348 eV (in P3) when replacing OCH, Cl on H of P3 corresponding to E = - 3575 eV (P4), - 4264 eV (P5).

The goals of this study were to assess our rates of ECMO-related ALI and bleeding and to evaluate the efficacy of strategies to prevent them, such as distal perfusion cannula (DPC) and ultrasound-guided cannulation.
Methods: This is a single-center retrospective cohort study of adult patients placed on peripheral VA-ECMO at a tertiary medical center between 2014 and 2018.
Background: The comorbidity-polypharmacy score (CPPS) was developed to quantify the severity of comorbidities of patients with geriatric trauma. CPPS is the sum of the number of medications and comorbidities, and is thus objective, user-friendly, and potentially adaptable to many clinical situations. We sought to understand if CPPS associates with outcomes and mortality after common vascular surgery procedures.

This study identifies modifiable factors contributing to LTF after vascular surgery and the factors' effect on short- and long-term clinical outcomes.
Methods: This is a retrospective single-center cohort study of 440 consecutive adult patients who underwent carotid endarterectomy, infrainguinal bypass, percutaneous lower extremity revascularization, or endovascular aortic aneurysm repair at Northwestern Memorial Hospital between November 2011 and November 2013.

The global nutrition transition has contributed to child obesity and dental caries in developing countries, including Vietnam. Few studies have described the nutrition and oral health of mothers and children. This a descriptive study of the nutrition and oral health characteristics of a convenience sample of 571 children aged 2 to 5 years and their mothers from 5 urban preschools in Central and South Vietnam.

Objectives: We investigated the relationships among early childhood caries (ECC), mouth pain, and nutritional status in children aged 1 to 6 years in Southern and Central Vietnam.
Methods: A total of 593 parent-child pairs were recruited from 5 kindergartens or preschools in Ho-Chi Minh City and Da Nang. Parents completed surveys about dietary habits, oral health practices, and children's mouth pain experience; children received anthropometric assessment and dental examinations.
Membranes undergo severe changes under oxidative stress conditions due to the creation of oxidized phospholipid (OxPL) species, which possess molecular properties quite different from their parental lipid components. These OxPLs play crucial roles in various pathological disorders and their occurrence is involved in the onset of intrinsic apoptosis, a fundamental pathway in programmed mammalian cell death. However, the molecular mechanisms by which these lipids can exert their apoptotic action via their host membranes (e.
