Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, and its incidence rate is rapidly growing. It is necessary to understand the pathogenesis of PTC to develop effective diagnosis methods. Promoter methylation has been recognized to contribute to the alterations in gene expression observed in tumorigenesis. Our RNA-seq data(More)
Three C19 diterpenoid alkaloids were isolated and purified from the lateral roots of Aconitum carmichaeli Debx. (Fuzi in Chinese) by high-speed counter-current chromatography (HSCCC). A mixture of n-hexane-ethyl acetate-methanol-water (3:5:4:5, v/v/v/v) was used as the two phase solvent system. The lower phase was used as the mobile phase and was operated(More)
Leukoaraiosis (LA) describes abnormal changes in the cerebral white matter frequently seen on CT and MRI in older adults. Its appearance indicates mild brain injury, and it is often regarded as a mark of senile dementia. Through the analysis of related risk factors of 6000 patients with LA diagnosed by cranial MRI in our department, we found that age,(More)
OBJECTIVE The aim of this study was to test the efficacy of a 12-month lifestyle intervention in improving cardiovascular disease risk factors in community-based menopausal transition and early postmenopausal women in China. METHODS One hundred healthy menopausal transition and early postmenopausal women aged 40 to 60 years were randomly assigned to(More)
The effect of pressure on the crystalline structure and superconducting transition temperature (T(c)) of the 111-type Na(1-x)FeAs system using in situ high-pressure synchrotron X-ray powder diffraction and diamond anvil cell techniques is studied. A pressure-induced tetragonal to tetragonal isostructural phase transition was found. The systematic evolution(More)
Although titanium (Ti) implants are considered to be an optimal choice for the replacement of missing teeth, it remains difficult to obtain sufficient osseointegration in patients with type 2 diabetes mellitus (T2DM). The present study aimed to investigate whether adipose-derived stem cells (ASCs) may be used to improve Ti implant osseointegration in T2DM(More)
OBJECTIVE To analyse the synergistic effect of polymorphism of the tandem repeat sequence u-VNTR of 5-hydroxytryptamine 2A (5-HT2A) receptor gene and monoamine oxidase A (MAOA) gene on the negative emotion in frontal lobe of patients with depression through functional magnetic resonance imaging (fMRI) technique. METHODS Functional magnetic resonance(More)
Formamidinium lead iodide (FAPbI3) perovskite as a superior solar cell material was investigated in two polymorphs at high pressures using in situ synchrotron X-ray diffraction, FTIR spectroscopy, photoluminescence (PL) spectroscopy, electrical conductivity (EC) measurements, and ab initio calculations. We identified two new structures (i.e., Imm2 and Immm)(More)
The bromo-substituted bisdiselenazolyl radical 4b (R(1) = Et, R(2) = Br) is isostructural with the corresponding chloro-derivative 4a (R(1) = Et, R(2) = Cl), both belonging to the tetragonal space group P(4)2(1)m and consisting of slipped π-stack arrays of undimerized radicals. Variable temperature, ambient pressure conductivity measurements indicate a(More)
Variable pressure and temperature conductivity measurements on the bisthiaselenazolyl radical dimer [1a](2) have established the presence of a weakly metallic state over the pressure range 5-9 GPa. To explore the origin of this metallization we have examined the crystal and molecular structure of [1a](2) as a function of pressure. At ambient pressure the(More)
