3.0 T unenhanced Dixon water-fat separation whole-heart coronary magnetic resonance angiography: compressed-sensing sensitivity encoding imaging versus conventional 2D sensitivity encoding imaging.

This study was aimed to investigate 3.0 T unenhanced Dixon water-fat whole-heart CMRA (coronary magnetic resonance angiography) using compressed-sensing sensitivity encoding (CS-SENSE) and conventional sensitivity encoding (SENSE) in vitro and in vivo. The key parameters of CS-SENSE and conventional 1D/2D SENSE were compared in vitro phantom study.

[Application regularity and solution strategies of mineral medicine Cinnabaris in pediatric preparations].

Mineral medicine is a characteristic element of advantage of traditional Chinese medicine(TCM), which embodies unique scientific connotation. Cinnabaris is a characteristic drug in Chinese medicinal preparations, especially in Chinese medicinal pediatric preparations. Because of the adverse reactions caused by mercury contained, the safety and application of Cinnabaris have attracted much attention.

Unenhanced Whole-Heart Coronary MRA: Prospective Intraindividual Comparison of 1.5-T SSFP and 3-T Dixon Water-Fat Separation GRE Methods Using Coronary Angiography as Reference.

Coronary MRA is commonly performed at 1.5 T using SSFP acquisitions. Coronary MRA performed at 3 T using SSFP is limited due to impaired fat suppression and has been typically investigated using contrast-enhanced techniques.

Artificial intelligence study on left ventricular function among normal individuals, hypertrophic cardiomyopathy and dilated cardiomyopathy patients using 1.5T cardiac cine MR images obtained by SSFP sequence.

Objectives: To evaluate the performance of a deep learning-based method to automatically quantify left ventricular (LV) function from MR images in different cardiomyopathy.

Methods: This retrospective study included MRI data sets from 2013 to 2020. Data on left ventricular function from patients with hypertrophic cardiomyopathy (HCM), patients with dilated cardiomyopathy (DCM), and healthy participants were analyzed.

[Effects of Nitrogen Fertilizer and Straw Returning Methods on NO Emissions in Wheat-Maize Rotational Soils].

In order to explore the impacts of nitrogen fertilizer and straw returning methods on NO emissions, a two-factor split-zone design was adopted for experimentation under the winter wheat-summer maize rotation model in the Guanzhong area of Shanxi, China. The main areas of interest were conventional nitrogen (G) and reduced nitrogen (70% G); the sub-areas were straw no return (N), straw return (S), and straw return + biochar (SB); we analyzed their impacts on NO emissions and crop yield, and the relationships with related impact factors. The results showed that the NO emissions peaks appeared in the wheat season and maize season treatments within 5-16 days after fertilization, and also appeared after rainfall.

High ACTN1 Is Associated with Poor Prognosis, and ACTN1 Silencing Suppresses Cell Proliferation and Metastasis in Oral Squamous Cell Carcinoma.

Purpose: Oral squamous cell carcinoma (OSCC) is a common malignancy of the oral cavity. As the survival rate of OSCC patients is low, it is crucial to explore new markers and therapeutic targets for early diagnosis of the disease. A high level of actinin alpha 1 (ACTN1) in patients could serve as an independent prognostic factor of acute myeloid leukemia.

Comprehensive evaluation of wild Cordyceps cicadae from different geographical origins by TOPSIS method based on the macroscopic infrared spectroscopy (IR) fingerprint.

Cordyceps cicadae is an entomogenous fungus that has been used as a valuable traditional Chinese herbal tonic, however, it can be difficult to discern the false from the genuine. In this study, the macroscopic IR fingerprint methods containing Fourier transform infrared spectroscopy (FT-IR) and second derivative infrared spectroscopy (SD-IR) were used to elucidate wild C. cicadae.

conidia possess antiproliferative and inducing apoptosis properties in gynaecological carcinoma cells.

is an entomogenous fungus that has been used as a traditional Chinese medicinal materials to treat different diseases, including cancer. However, conidia for inhibitory activity against breast cancer cells growth are still not systematically studied. The present aim was to elucidate the phytochemical composition of conidia and to explore relevant anti-cancer potential in gynaecological carcinoma MCF-7 and Hela cells.

Treatment of a mandibular functional shift in an adolescent boy with temporomandibular disorder and crossbites.

A mandibular functional shift usually poses a challenge for orthodontists, especially when it is accompanied by a temporomandibular disorder (TMD). Accurate diagnosis and complete elimination of the etiologic factors are the keys to an esthetic and stable outcome. This article describes the treatment of a teenager with a mandibular functional shift, TMD symptoms, and facial asymmetry resulting from an asymmetric maxillary arch form and multiple crossbites as occlusal interferences.

Mechanical loading induced expression of bone morphogenetic protein-2, alkaline phosphatase activity, and collagen synthesis in osteoblastic MC3T3-E1 cells.

Background: Bone morphogenetic protein (BMP)-2, alkaline phosphatase (ALP), and collagen type I are known to play a critical role in the process of bone remodeling. However, the relationship between mechanical strain and the expression of BMP-2, ALP, and COL-I in osteoblasts was still unknown. The purpose of this study was to investigate the effects of different magnitudes of mechanical strain on osteoblast morphology and on the expression of BMP-2, ALP, and COL-I.

4-Butyl-anilinium perchlorate.

In the crystal structure of the title salt, C(10)H(16)N(+)·ClO(4) (-), the 4-butyl-anilinium cation is mirror symmetric, the butyl C atoms and anilinium N atom and 1,4-position C atoms of the benzene ring being located on the mirror plane; the perchlorate anion is also mirror symmetric, with two O atoms and one Cl atom lying on the mirror plane. Trifurcated N-H⋯O hydrogen bonding is observed between the cation and anion in the crystal structure.

Isonicotinonitrile-4-methyl-benzoic acid (1/1).

The title structure, C(6)H(4)N(2)·C(8)H(8)O(2), is built up from an assembly of isonicotinonitrile and 4-methyl-benzoic acid mol-ecules and may be regarded as a co-crystal. The two planar mol-ecules [r.m.

5-(1H-Tetra-zol-5-yl)-1H-indole monohydrate.

Rapid tooth movement through distraction osteogenesis of the periodontal ligament in dogs.

Background: Animal models are needed for the study of rapid tooth movement into the extraction socket through distraction osteogenesis of the periodontal ligament.

Methods: Modified distraction devices were placed on eight dogs between the first and third mandibular premolars on the left sides; similar placement of traditional straight wise appliances on the right sides served as the control. The experimental distractors were activated (0.
