Qianwen Niu, Yu Pu, Xiaoping Li, Zhen Ma, Xinzhong Hu
This study measured the solvent retention capacities (SRCs) of flours from eight oat varieties and one wheat variety against different solvents to explore the swelling volume of oat flour with different solvents, and thus provide a theoretical basis for quick β-glucan analysis. The SRC profile consists of water SRC (WSRC), 50% sucrose SRC (SSRC), 5% lactic acid SRC (LASRC), 5% Na₂CO₃ SRC (SCASRC), NaCl SRC (SCSRC), CaCl₂ SRC (CCSRC), FeCl₃ SRC (FCSRC), sodium cholate SRC (SCHSRC), NaOH (pH 10) SRC (SHSRC), Na₂CO₃ (pH 10) SRC (SCABSRC) and SDS (pH 10) SRC (SDSSRC) values, and a Chopin SRC kit was used to measure the SRC value...

BACKGROUND: To date, sex difference in outcomes among patients with intracranial atherosclerosis (ICAS) has rarely been discussed in China as well as in the world. This study aimed to estimate the sex difference in outcomes among patients with ICAS in Chinese cerebral ischemia patients. METHODS: We analyzed 1,335 men and women with ICAS who were enrolled in the Chinese Intracranial Atherosclerosis study. They were followed-up for ischemic stroke recurrence, any cause of death, cerebral vascular events (including transient ischemic attack, ischemic and hemorrhagic stroke), combined end points (including cerebral vascular events, angina or myocardial infarction, pulmonary embolism, peripheral vascular events), and unfavorable outcome (modified Rankin scale score of 3-6) at 1 year...

Contaminated soil organic matter from the Rocky Flats Environmental Technology Site (RFETS) has been previously shown to accumulate plutonium (Pu) in a colloidal sub-fraction and hypothesized to contain cutin-like chemical structures cross-linked with hydroxamate functionality. The present study further characterizes this high Pu-affinity sub-fraction using electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI-FTICRMS) and discovers additional sub-structural components. The Pu-enriched fraction was extracted and purified through a series of ultrafiltration and isoelectric focusing (IEF) electrophoresis steps...

Developing facile and robust technologies for effective enrichment of uranium from the seawater is of great significance for resource sustainability and environmental safety. By exploiting the mussel-inspired polydopamine (PDA) chemistry, diverse types of PDA-functionalized sorbents including magnetic nanoparticle (MNP), ordered mesoporous carbon (OMC) and glass fiber carpet (GFC) were synthesized. The PDA functional layers with abundant catechol and amine/imine groups provided an excellent platform for the binding to uranium...

Autologous chondrocyte implantation for cartilage repair represents a challenge because strongly limited by chondrocytes' poor expansion capacity in vitro. Mesenchymal stem cells (MSCs) can differentiate into chondrocytes, while mechanical loading has been proposed as alternative strategy to induce chondrogenesis excluding the use of exogenous factors. Moreover, MSC supporting material selection is fundamental to allow for an active interaction with cells. Here, we tested a novel thermo-reversible hydrogel composed of 8% w/v methylcellulose (MC) in a 0...

Mural cells (pericytes and vascular smooth muscle cells) are essential for the regulation of vascular networks and maintenance of vascular integrity, but their origins are diverse in different tissues and not known in the organs that arise from the ectoderm, such as skin. Here, we show that tissue-localized myeloid progenitors contribute to pericyte development in embryonic skin vasculature. A series of in vivo fate-mapping experiments indicates that tissue myeloid progenitors differentiate into pericytes...

DNA methylation and demethylation are two important mechanisms of epigenetics, which is important in the study of cell differentiation, proliferation, and senescence. During osteogenic differentiation of stem cells, the expression of osteogenic specific genes and demethylated promoters is upregulated, whereas the expression of pluripotent genes and hypermethylated promoters is downregulated. The dynamic changes and balance between DNA methylation and demethylation are important for the coordination of gene expression and the inhibition of improper phenotypes...

β-Thalassemia is associated with several abnormalities of the innate immune system. Neutrophils in particular are defective, predisposing patients to life-threatening bacterial infections. The molecular and cellular mechanisms involved in impaired neutrophil function remain incompletely defined. We used the Hbb(th3/+) β-thalassemia mouse and HbE/β-thalassemia patients to investigate dysregulated neutrophil activity. Mature neutrophils from Hbb(th3/+) mice displayed a significant reduction in chemotaxis, opsonophagocytosis and production of reactive oxygen species (ROS), closely mimicking the defective immune functions observed in β-thalassemia patients...

Although the polar regions have not been industrialised, numerous contaminants originating from human activity are detectable in the Arctic environment. This study reports evidence of (240)Pu/(239)Pu atomic ratios in the tundra and initial soils from different parts of west and central Spitsbergen and recognizes possible environmental inputs of non-global fallout Pu. The average atomic ratio of (240)Pu/(239)Pu equal to 0.179 (ranging between 0.129 and 0.201) in tundra soils are comparable to the characteristic ratio for global fallout (0...

The androgen receptor (AR) plays a critical role as a driver of castration-resistant-prostate cancer (CRPC). Our previous studies demonstrated that disruption of transforming growth factor-β (TGF-β) signaling via introduction of dominant-negative TGF-β type II receptor (DNTGF-RβII) in the prostate epithelium of transgenic adenocarcinoma of the prostate (TRAMP) mice accelerated tumor. This study investigated the consequences of disrupted TGF-β signaling on prostate tumor growth under conditions of castration-induced androgen deprivation (ADT) in the pre-clinical model DNTGFβRII...

Estrogen receptors (Er) play a critical role in vitellogenesis. Three ers (erα, erβ1 and erβ2) and vitellogenins (vtg-A, vtg-B and vtg-C) subtypes were isolated in various fish species, while the contribution of each Er to the regulation of vtgs expression was not analyzed in detail. Here, erα, erβ1 and erβ2 were cloned and all were found to be expressed in female liver in Scatophagus argus. During proteic vitellogenesis stage, erα was simultaneously up-regulated, while erβ1 and erβ2 were not, with three vtgs in female liver...

This study aimed to investigate the neurotoxicity of exosomes to cultured neuroblastoma and neurons in vitro and to mature and newborn neurons in the hippocampus in vivo. Recent in vitro and in vivo studies have shown that exosomes, small membranous vesicles secreted from many cell types, contain pathogenic proteins including full-length amyloid precursor protein (flAPP) and amyloid precursor protein (APP) metabolites. However, the function of these exosomes in Alzheimer disease (AD) has not been much explored...

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare condition in the elderly and can appear as a first presentation of various types of rheumatic and malignant diseases. We presented a 62-year-old man with the diagnosis of RS3PE based on the clinical sign and laboratory data. Because of the possibility of associated malignancies in RS3PE, FDG PET/CT was performed to exclude occult tumors. The images showed multiple, symmetrically, diffusely increased F-FDG uptake in the soft tissue around joints and bones in the shoulders, hips, knees, and ankles...

Reversible denaturation of Pseudomonas aeruginosa cytochrome c551 (PAc551) could be followed using five systematic urea derivatives that differ in the alkyl chain length, i.e. urea, N-methylurea (MU), N-ethylurea (EU), N-propylurea (PU), and N-butylurea (BU). The BU concentration was the lowest required for the PAc551 denaturation, those of PU, EU, MU, and urea being gradually higher. Furthermore, the accessible surface area difference upon PAc551 denaturation caused by BU was found to be the highest, those by PU, EU, MU, and urea being gradually lower...

Ultrathin three-dimensional topological insulator films are promising for use in field effect devices. (Bi1-xSbx)2Se3 ultrathin films were fabricated on SrTiO3 substrate, where large resistance changes of ∼25000% could be achieved using the back gate voltage. We suggest that the large ON/OFF ratio was caused by the combined effect of Sb-doping and the reduction of film thickness down to the ultrathin regime. The crossover of different quantum transport under an electric field may form the basis for TI-based spin transistors with large ON/OFF ratios in the future...
