Temperature and Strain Rate Dependence on the Tensile Mechanical Properties, Constitutive Equations, and Fracture Mechanisms of MarBN Steel.

The effect of strain rate and temperature on the thermomechanical behavior and microstructure of MarBN steel is studied with the strain rates of 5 × 10 and 5 × 10 s from room temperature (RT) to 630 °C. At high strain rates of 5 × 10 s, the Holloman and Ludwigson equations can better predict tensile plastic properties. In contrast, under low strain rates of 5 × 10 s, coupling of the Voce and Ludwigson equations appears to predict the flow relationship at RT, 430, and 630 °C.

Analysis of the Tensile Deformation Behaviors and Microstructure Characterization under Various Temperatures of MarBN Steel by EBSD.

The uniaxial tensile behavior of MarBN steel with a constant strain rate of 5 × 10 s under various temperatures ranging from room temperature to 630 °C was analyzed. This study aimed to identify the effect of the temperature on the tensile behavior and to understand the microstructure deformation by electron backscatter diffraction. The tensile results showed that the yield and ultimate tensile strength decreased with increasing temperature.

Comparative analysis of lipid components in fresh (raw) and its dried products by using high-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (HPLC/Q-TOF-MS).

The lipids of the oyster () have a special physiological activity function, which is essential to maintain human health. However, comprehensive research on their lipids species and metabolism is not so common. In our study, based on the high-performance liquid chromatography/quadrupole time-of-flight mass spectrometer (HPLC/Q-TOF-MS), the non-targeted lipidomics research of fresh and dried products was determined.

TLR4 agonist activity of Alcaligenes lipid a utilizes MyD88 and TRIF signaling pathways for efficient antigen presentation and T cell differentiation by dendritic cells.

Alcaligenes faecalis was previously identified as an intestinal lymphoid tissue-resident commensal bacteria, and our subsequent studies showed that lipopolysaccharide and its core active element (i.e., lipid A) have a potent adjuvant activity to promote preferentially antigen-specific Th17 response and antibody production.

Tensile Behavior, Constitutive Model, and Deformation Mechanisms of MarBN Steel at Various Temperatures and Strain Rates.

To reduce harmful gas emission and improve the operational efficiency, advanced ultra-supercritical power plants put forward higher requirements on the high temperature mechanical properties of applied materials. In this paper, the tensile behavior and deformation mechanisms of MarBN steel are discussed at different strain rates (5 × 10 s, 5 × 10 s, and 5 × 10 s) under room temperature and 630 °C. The results show that the tensile behavior of the alloy is dependent on temperature and strain rate, which derived from the balance between the average dislocation velocity and dislocation density.

NtAGO1 positively regulates the generation and viral resistance of dark green islands in Nicotiana tabacum.

Dark green islands (DGIs) are the outcome of post-transcriptional gene silencing (PTGS) in antiviral immunity, but their characteristics related to PTGS remain largely unknown. In this study, the cucumber mosaic virus (CMV) was inoculated on Nicotiana tabacum plants to explore the PTGS features of DGIs. Our results showed that higher expressions of PTGS-associated genes, especially NtAGO1, present in DGIs.

Chemically Synthesized Lipid A as an Adjuvant to Augment Immune Responses to Type B Conjugate Vaccine.

We previously identified spp. as a commensal bacterium that resides in lymphoid tissues, including Peyer's patches. We found that -derived lipopolysaccharide acted as a weak agonist of Toll-like receptor four due to the unique structure of lipid A, which lies in the core of lipopolysaccharide.

Lipopolysaccharide Derived From the Lymphoid-Resident Commensal Bacteria Functions as an Effective Nasal Adjuvant to Augment IgA Antibody and Th17 Cell Responses.

spp., including , is a gram-negative facultative bacterium uniquely residing inside the Peyer's patches. We previously showed that -derived lipopolysaccharides ( LPS) acts as a weak agonist of toll-like receptor 4 to activate dendritic cells and shows adjuvant activity by enhancing IgG and Th17 responses to systemic vaccination.

Chemically Synthesized Lipid A Shows a Potent and Safe Nasal Vaccine Adjuvant Activity for the Induction of -Specific IgA and Th17 Mediated Protective Immunity.

Effective and safe vaccine adjuvants are needed to appropriately augment mucosal vaccine effects. Our previous study demonstrated that lipopolysaccharide (LPS) from Peyer's patch resident stimulated dendritic cells to promote the production of mucosal immunity-enhancing cytokines (e.g.

Adjuvant Activity of Synthetic Lipid A of , a Gut-Associated Lymphoid Tissue-Resident Commensal Bacterium, to Augment Antigen-Specific IgG and Th17 Responses in Systemic Vaccine.

spp. are identified as commensal bacteria and have been found to inhabit Peyer's patches in the gut. We previously reported that -derived lipopolysaccharides (LPS) exerted adjuvant activity in systemic vaccination, without excessive inflammation.

Investigation of etoxazole metabolites in citrus, soil and earthworms by ultra-performance liquid chromatography with time-of-flight mass spectrometry.

Etoxazole is a newly registered and widely used acaricide. However, its metabolites were not fully understood and might exhibit similar or even higher toxicity than parent compound. Therefore, in this study, the metabolites of etoxazole in citrus, soil and earthworms were firstly identified by an ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS).

Thevetiaflavone from Wikstroemia indica ameliorates PC12 cells injury induced by OGD/R via improving ROS‑mediated mitochondrial dysfunction.

Cerebral ischemia and following reperfusion affects many people worldwide. To discover efficient therapeutic approaches, numerous natural products have been investigated. The current study investigated the protective effects of thevetiaflavone, a natural flavonoid obtained from Wikstroemia indica, and the associated mechanisms using PC12 cells induced by oxygen and glucose deprivation.

Cutaneous protothecosis in patient with diabetes mellitus and review of published case reports.

Protothecosis is an opportunistic infection caused by Prototheca, usually called as saprophytes, and is frequently found in natural and living surroundings with low virulence, but may cause chronic infection in immunocompromised individuals. We report a case of cutaneous protothecosis with zopfii var. portoricensis infection in a 66-year-old diabetic woman following hand surgery on middle right finger.
