Polygonumnolides A1–B3, minor dianthrone derivatives from the roots of Polygonum multiflorum Thunb

Seven new dianthrone glycosides, named polygonumnolides A1–B3 (1–7), were isolated from the 70 % EtOH extract of the dried roots of Polygonum multiflorum Thunb. using column chromatography and preparative high-performance liquid chromatography. Their structures were determined by 1D and 2D NMR and mass spectroscopy. The isolated compounds were evaluated for their cytotoxic effects ...

methods applied to power systems. Zheng YAN received his B .Sc., M. Sc . and Ph .D. degrees, all in Electrical Engineering, from Shanghai Jiao Tong University in 1984 , and Tsinghua University in 1987 and

A Comprehensive Analysis on Spread and Distribution Characteristic of Antibiotic Resistance Genes in Livestock Farms of Southeastern China

The pollution of antibiotic resistance genes (ARGs) in livestock farms is a problem which need to be paid more attention to, due to the severe resistance dissemination and the further human health risk. In this study, all the relevant exposure matrices (manure, soil and water) of sixteen animal farms in Southeastern China were sampled to determine twenty-two ARGs conferring ...

Shaanxi Province for excellent researchers from abroad (Grant No. 680F1303), as well as Aalto University. Zheng Yan (M’06-SM’14) is currently a professor at the Xidian University, Xi’an, China and a

Association of microRNA-33a Molecular Signature with Non-Small Cell Lung Cancer Diagnosis and Prognosis after Chemotherapy

Objective This study aims to explore the expression pattern and prognostic significance of miR-33a in non-small cell lung cancer (NSCLC) treated with adjuvant chemotherapy. Methods MiR-33aexpression in NSCLC was analyzed in silico using the GEO database and was subsequently confirmed by quantitative RT-PCR in 147 NSCLC biopsies. Among these, 32 of these biopsies were paired with ...

Fat Intake Is Not Linked to Prostate Cancer: A Systematic Review and Dose-Response Meta-Analysis

Background Since the late 1960s, the average global supply of fat has increased by 20 g per capita per day. While fat intake has been considered a potential risk factor for prostate cancer (Pca), the hypothesis from previous epidemiologic studies remained equivocal. Materials and Methods Relevant cohort studies were identified through a literature search in PubMed, ScienceDirect ...

Associations between maternal lipid profile and pregnancy complications and perinatal outcomes: a population-based study from China

Background Dyslipidemia in pregnancy are associated with gestational diabetes mellitus (GDM), preeclampsia, preterm birth and other adverse outcomes, which has been extensively studied in western countries. However, similar studies have rarely been conducted in Asian countries. Our study was aimed at investigating the associations between maternal dyslipidemia and adverse pregnancy ...

Changes in snoRNA and snRNA Abundance in the Human, Chimpanzee, Macaque, and Mouse Brain

Small nuclear and nucleolar RNAs (snRNAs and snoRNAs) are known to be functionally and evolutionarily conserved elements of transcript processing machinery. Here, we investigated the expression evolution of snRNAs and snoRNAs by measuring their abundance in the frontal cortex of humans, chimpanzees, rhesus monkeys, and mice. Although snRNA expression is largely conserved, 44% of ...

Eight-Shaped Hatching Increases the Risk of Inner Cell Mass Splitting in Extended Mouse Embryo Culture

Increased risk of monozygotic twinning (MZT) has been shown to be associated with assisted reproduction techniques, particularly blastocyst culture. Interestingly, inner cell mass (ICM) splitting in human ‘8’-shaped hatching blastocysts that resulted in MZT was reported. However, the underlying cause of MZT is not known. In this study, we investigated in a mouse model whether in ...

Precise asymptotics in the law of the iterated logarithm for R / S statistic

Let { X , X n , n ≥ 1 } be a sequence of i.i.d. random variables which is in the domain of attraction of the normal law with zero mean and possibly infinite variance, Q ( n ) = R ( n ) / S ( n ) be the rescaled range statistic, where R ( n ) = max 1 ≤ k ≤ n { ∑ j = 1 k ( X j − X ¯ n ) } − min 1 ≤ k ≤ n { ∑ j = 1 k ( X j − X ¯ n ) } , S 2 ( n ) = ∑ j = 1 n ( X j − X ¯ n ) 2 / n and ...

Ubiquitin-like prokaryotic MoaD as a fusion tag for expression of heterologous proteins in Escherichia coli

Background Eukaryotic ubiquitin and SUMO are frequently used as tags to enhance the fusion protein expression in microbial host. They increase the solubility and stability, and protect the peptides from proteolytic degradation due to their stable and highly conserved structures. Few of prokaryotic ubiquitin-like proteins was used as fusion tags except ThiS, which enhances the ...

A TNM Staging System for Nasal NK/T-Cell Lymphoma

Ann Arbor stage has limited utility in the prognostication and treatment decision making in patients with NK/T-cell lymphoma (NKTCL), as NKTCL is almost exclusively extranodal and the majority is localized at presentation for which radiotherapy is the most important treatment and local invasiveness is the most important prognostic factor. In this study, we attempted to establish a ...

Glycolipid metabolic status of overweight/obese adolescents aged 9- to 15-year-old and the BMI-SDS/BMI cut-off value of predicting dyslipidemiain boys, Shanghai, China: a cross-sectional study

Background The prevalence of adolescents’ obesity and overweight has dramatically elevated in China. Obese children were likely to insulin resistance and dyslipidemia, which are risk factors of cardiovascular diseases. However there was no cut-off point of anthropometric values to predict the risk factors in Chinese adolescents. The present study was to investigate glycolipid ...

Indicators of Child Health, Service Utilization and Mortality in Zhejiang Province of China, 1998–2011

Objective To investigate the levels of primary health care services for children and their changes in Zhejiang Province, China from 1998 to 2011. Methods The data were drawn from Zhejiang maternal and child health statistics collected under the supervision of the Health Bureau of Zhejiang Province. Primary health care coverage, hospital deliveries, low birth weight, postnatal ...

Prokaryotic Ubiquitin-Like ThiS Fusion Enhances the Heterologous Protein Overexpression and Aggregation in Escherichia coli

Fusion tags are commonly employed to enhance target protein expression, improve their folding and solubility, and reduce protein degradation in expression of recombinant proteins. Ubiquitin (Ub) and SUMO are highly conserved small proteins in eukaryotes, and frequently used as fusion tags in prokaryotic expression. ThiS, a smaller sulfur-carrier protein involved in thiamin ...
