Valley manipulation by external fields in two-dimensional materials and their hybrid systems.

Investigating two-dimensional (2D) valleytronic materials opens a new chapter in physics and facilitates the emergence of pioneering technologies. Nevertheless, this nascent field faces substantial challenges, primarily attributed to the inherent issue of valley energy degeneracy and the manipulation of valley properties. To break these constraints, the application of external fields has become pivotal for both generating and manipulating the valley properties of 2D systems.

Quantitative analysis of anthocyanins and flavonoids in purple and green leaves of by UPLC-MS/MS techniques.

Ultra performance liquid chromatography-high resolution mass spectrometry (UPLC-MS/MS) were used to target quantitative determination anthocyanins and flavonoids in the fresh leaves (purple and green) of . The results showed that the content of total anthocyanins was 99.68 μg/g (Fresh Weight, FW) in purple leaves and 29.

Magnetic and Ferroelectric Manipulation of Valley Physics in Janus Piezoelectric Materials.

The realization of multiferroic materials offers the possibility of multifunctional electronic device design. However, the coupling between the multiferroicity and piezoelectricity in Janus materials is rarely reported. In this study, we propose a mechanism for manipulating valley physics by magnetization reversing and ferroelectric switching in multiferroic and piezoelectric material.

Active Asymmetric Electron-Transfer Effect on the Enhanced Piezoelectricity in MoTO (T = S, Se, or Te) Monolayers and Bilayers.

Development of piezoelectric materials is limited partly due to the incompleteness of internal mechanism and the lack of vertical piezoelectricity. Herein, we theoretically identify the stable MoTO (T = S, Se, or Te) monolayers and bilayers. When two elements are given but another element can be changed, the larger the electronegativity difference ratio is, the stronger the piezoelectricity will be.

[Polarized activation affects iron metabolism in macrophages].

The aim of this study was to investigate the effects of polarization program on the ability of macrophages to regulate iron metabolism. M1 and M2 macrophages were propagated in vitro from porcine alveolar macrophages 3D4/2 and polarized by cytokines. The 3D4/2 macrophages were treated with 20 ng/mL interferon gamma (IFN-γ) and 10 ng/mL interleukin-4 (IL-4) combined with 10 ng/mL macrophage colony-stimulating factor (M-CSF) to induce polarization to M1 and M2, respectively.

Improved quantification of immune-gold labeling and its use to compare the distribution of cellular factors among sub-chloroplast compartments.

Quantification of immuno-gold labeling can provide valuable information on the quantity and localization of a target within a region of interest (ROI). Background subtraction usually requires preparation of material with a deliberately reduced amount of target component often by gene knockout/knockdown. This paper reports a modified method without the need for gene knockout/knockdown, by using a region outside the ROI as a background and non-immune serum to verify the reliability of the data.

Plant begomoviruses subvert ubiquitination to suppress plant defenses against insect vectors.

Most plant viruses are vectored by insects and the interactions of virus-plant-vector have important ecological and evolutionary implications. Insect vectors often perform better on virus-infected plants. This indirect mutualism between plant viruses and insect vectors promotes the spread of virus and has significant agronomical effects.

Instantaneous frequency from Hilbert-Huang transformation of digital volume pulse as indicator of diabetes and arterial stiffness in upper-middle-aged subjects.

To investigate the value of decomposed short-time digital volume pulse (DVP) signals in discerning systemic vascular anomaly in diabetic patients, demographic and anthropometric parameters, serum lipid profile, fasting blood glucose and glycated hemoglobin (HbA1c) levels were obtained from 29 healthy adults (Group 1) and 29 age-matched type 2 diabetes mellitus patients (Group 2). Six-second DVP signals from right index finger acquired through photoplethysmography were decomposed using ensemble empirical mode decomposition. Using one intrinsic mode function (IMF5), stiffness index (SI) and instantaneous energy of maximal energy (f) were obtained.

[Catalytic Degradation of Diclofenac Sodium over the Catalyst of 3D Flower-like alpha-FeOOH Synergized with H2O2 Under Visible Light Irradiation].

Three dimensional (3D) flower-like alpha-FeOOH nanomaterials were prepared by oil bath reflux method using FeSO4, urea, ethanol and water, and the products which were characterized by XRD, FT-IR and SEM techniques. The SEM images showed that the 3D flower-like samples consisted of nanorods with a length of 400-500 nm and a diameter of 40-60 nm. The catalytic performance of the samples was evaluated by catalytic degradation of diclofenac sodium using H2O2 as the oxidant under simulated visible light.

Effect of Bak Foong Pills on the expression of β-amyloid in rat retina with optic nerve transection.

Aim: To investigate the effect of Bak Foong Pills (BFP) on the expression of β-amyloid (Aβ) in rats retina with optic nerve transection, and its roles and possible mechanisms in protecting optic nerve damage.

Methods: Seventy-two healthy, Sprague-Dawley, adult rats were randomly assigned to three groups: negative control group (control group), optic nerve transection group (model group) and BFP treatment group (BFP group, 100μg/mL) followed by establishing optic nerve transection model. The expression of Aβ was measured at 48 hours by Western-blotting.

[Prokaryotic expression and immuno-localization of replication protein gene of Tobacco curly shoot virus].

The replication protein (Rep) gene of Tobacco curly shoot virus (TbCSV) Y35 isolate was obtained from the infected tobacco plants by PCR and cloned into expression vector pGEX-4T-1 to generate the recombinant plasmid pGEX-Y35Rep. The recombinant plasmid was introduced into Escherichia coli strain BL21(DE3) pLys S, and TbCSV Rep fusion protein was expressed with induction by IPTG and some products were soluble. The Rep fusion protein was purified with GST-Sepharose 4B affinity chromatography and its polyclonal antibody was produced in a rabbit.

Expression of a begomoviral DNAbeta gene in transgenic Nicotiana plants induced abnormal cell division.

An increasing number of monopartite begomoviruses are being identified that a satellite molecule (DNAbeta) is required to induce typical symptoms in host plants. DNAbeta encodes a single gene (termed betaC1) encoded in the complementary-sense. We have produced transgenic Nicotiana benthamiana and N.
