Research on detection of potato varieties based on spectral imaging analytical algorithm.

Potatoes are popular among consumers due to their high yield and delicious taste. However, due to the numerous varieties of potatoes, different varieties are suitable for different processing methods. Therefore, it is necessary to distinguish varieties after harvest to meet the needs of processing enterprises and consumers.

Proanthocyanidins Alleviate Cadmium Stress in Industrial Hemp ( L.).

Industrial hemp ( L.), an annual herbaceous cash crop, is widely used for the remediation of heavy metal-contaminated soils due to its short growth cycle, high tolerance, high biomass, and lack of susceptibility to transfer heavy metals into the human food chain. In this study, a significant increase in proanthocyanidins was found in Yunnan hemp no.

Association of Intratumoral Microbiota With Prognosis in Patients With Nasopharyngeal Carcinoma From 2 Hospitals in China.

Importance: Microbiota-tumor interactions have qualified microbiota as a promising prognostic biomarker in various types of cancers. Although the nasopharynx acts as a crucial niche of the upper respiratory tract microbiome, whether the intratumoral microbiota exists and its clinical significance in nasopharyngeal carcinoma (NPC) remain uncertain.

Objective: To evaluate the clinical significance of intratumoral microbiota for individual prognostication in patients with NPC.

Anomalous Blue Shift of Exciton Luminescence in Diamond.

Generally speaking, for a semiconductor, the temperature dependence of excitonic emission corresponds to that of its band gap. However, an anomalous behavior is exhibited by the excitonic luminescence of diamond where as the temperature increases (from 10 to 300 K), its indirect exciton luminescence peak displays a spectral-distinguishable blue shift, whereas the indirect band-gap absorption shows a weak red shift. According to experimental high-resolution deep-ultraviolet spectra and theoretical analysis, the weak red shift of its indirect band gap is ascribed to its large Debye temperature (Θ ≈ 2220 K), which makes the lattice constant change comparatively little in a large temperature range, so the change of its band gap is relatively small; in this case, as the temperature rises, the thermal population of valence-band holes that moves to a high-energy state far away from the Fermi surface contributes to the macroscopic blue shift of its excitonic emission.

Prediction for Cycloplegic Refractive Error in Chinese School Students: Model Development and Validation.

Purpose: To predict cycloplegic refractive error using measurements obtained under noncycloplegic conditions.

Method: Refractive error was measured in 5- to 18-year-old Chinese students using a NIDEK autorefractor before and after administration of 0.5% tropicamide.

Calhm2 governs astrocytic ATP releasing in the development of depression-like behaviors.

Extracellular ATP is a widespread cell-to-cell signaling molecule in the brain, where it functions as a neuromodulator by activating glia and neurons. Although ATP exerts multiple effects on synaptic plasticity and neuro-glia interactions, as well as in mood disorders, the source and regulation of ATP release remain to be elaborated. Here, we define Calhm2 as an ATP-releasing channel protein based on in vitro and in vivo models.

Increased ratio of high sensitivity C-reactive protein to interleukin-10 as a potential peripheral biomarker of schizophrenia and aggression.

Background: Many studies have indicated that immune dysfunction might be involved in the physiopathology of schizophrenia and aggression. This study aimed to investigate the correlation between high-sensitivity C-reactive protein (hsCRP), interleukin (IL)-10 and clinical characteristics, especially aggression, and to explore the potential role of hsCRP and IL-10 as plasma biomarkers of schizophrenia.

Methods: Forty-one patients with schizophrenia and forty healthy individuals were enrolled.

Hazard levels of warning signal words modulate the inhibition of return effect: evidence from the event-related potential P300.

Warning signal words are often used to convey valuable information about potential dangers in everyday life. In this study, we explored whether and how the hazard level of warning signal words modulated participants' attention to subsequent targets. Event-related potentials with high temporal resolution were employed in a cue-target paradigm.

Efficient gene editing in adult mouse livers via adenoviral delivery of CRISPR/Cas9.

We developed an adenovirus-based CRISPR/Cas9 system for gene editing in vivo. In the liver, we demonstrated that the system could reach the level of tissue-specific gene knockout, resulting in phenotypic changes. Given the wide spectrum of cell types susceptible to adenoviral infection, and the fact that adenoviral genome rarely integrates into its host cell genome, we believe the adenovirus-based CRISPR/Cas9 system will find applications in a variety of experimental settings.

Stability and encapsulation efficiency of sulforaphane microencapsulated by spray drying.

Sulforaphane (SF) has received much attention because of its anticarcinogenic, antioxidant and anti-inflammatory properties, but it is quite unstable. Microencapsulation is one way to improve its stability. The aim of this work was to produce microcapsules containing sulforaphane using a spray drying technique.

Preparation and characterization of the agostic bonding molecules between metal and chlorine from the reactions of niobium and tantalum monoxide and dioxide molecules with monochloromethane in solid argon.

Reactions of niobium and tantalum monoxide and dioxide molecules with monochloromethane in solid argon have been investigated by infrared absorption spectroscopy and density functional theoretical calculations. The results show that the ground-state MO(x) (M = Nb, Ta, x = 1, 2) molecules react with CH(3)Cl to form the weakly bound MO(CH(3)Cl) and MO(2)(CH(3)Cl) complexes. The MO(CH(3)Cl) complexes rearrange to the more stable CH(2)ClM(O)H isomer upon visible light excitation, whereas the MO(2)(CH(3)Cl) complexes isomerize to the more stable CH(2)ClM(O)OH molecules under ultraviolet light irradiation.

Matrix isolation infrared spectroscopic and density functional theoretical study of the reactions of scandium and yttrium monoxides with monochloromethane.

Reactions of scandium and yttrium monoxide molecules (ScO and YO) with monochloromethane have been studied in solid argon by infrared absorption spectroscopy and density functional theoretical calculations. The metal monoxide molecules were prepared by laser-evaporation of bulk metal oxide targets. The results show that the ground state scandium and yttrium monoxide molecules reacted with CH(3)Cl to form two MO(CH(3)Cl) (M = Sc, Y) complex isomers spontaneously on annealing.

[Studies on the antilipid peroxidation of nine sorts of Chinese herbal medicines with the function of protecting liver].

The antilipid peroxidation of nine sorts of Chinese herbal medicines with the function of protecting liver, including Salivia miltiorrhiza, Hypericum japonicum, Scutellaria baicalensis, Callicarpa cathayana, Chrysanthemum indicum, Paeonia latiflora, Lysimachia christinae, Ligustrum lucidum (L1), Patrinia villosa (Pv) on hepatic homogenate of rat were tested. It was found that all tested medicines showed inhibition with dose-effect relationship, the inhibitory rate of L1 and Pv were lower than the other's. All results showed that these Chinese herbal medicines have strong antilipid peroxidation and are natural oxidation inhibitor.
