China has a historic system of wide cycle tracks, many of which are now encroached by cars, buses and bus stops. Even with these conditions, college students still bicycle. On campuses, students park their bikes on facilities ranging from kick-stand-plazas to caged sheds with racks, pumps and an attendant. In other countries, including Canada, some of the newer cycle tracks need to be wider to accommodate an increasing number of bicyclists. Other countries will also need to improve their bike parking, which includes garage-basement cages and two-tiered racks...

A novel Gram-stain-negative, aerobic, rod-shaped strain designated 166T was isolated from surface-sterilized root tissue of maize planted in the Fangshan District of Beijing, PR China. The 16S rRNA gene sequence analysis indicated that strain 166T belongs to the genus Rhizobium and is closely related to Rhizobium cellulosilyticum ALA10B2T and Rhizobium yantingense H66T with sequence similarities of 98.8 and 98.3 %, respectively. According to atpD and recA sequence analysis, the highest sequence similarity between strain 166T and R...

BACKGROUND: This study aimed to investigate the association between variability in hemoglobin A1c (HbA1c) and left ventricular (LV) diastolic function and incidence of symptomatic heart failure with preserved ejection fraction (HFpEF) in patients with type 2 diabetes mellitus (T2DM) and arterial hypertension. METHODS: A retrospective cohort study was conducted on eligible patients with T2DM and hypertension and without clinical signs or symptoms of heart failure in our hospital medical record database...

Plasmonic Au-Pd nanostructures have drawn significant attention for use in heterogeneous catalysis. In this study, palladium nanodendrite-tipped gold nanorods (PdND-T-AuNRs) were subjected to a facile fabrication under mild reaction conditions. The palladium amounts on the two tips were tunable. In the preparation of PdND-T-AuNRs, dense capped AuNRs, a low reaction temperature, and suitable stabilizing agents were identified as critical reaction parameters for controlling palladium nanodendrites deposited on both ends of AuNRs...

RATIONALE: Luminal subtype breast cancer, accounting for 70 to 80% of all breast cancers, has been reported to be associated with good prognosis. However, for the patients with large mass or worse mass position, omental flap transplantation may provide a new option for breast reconstruction. PATIENT CONCERNS: Ten patients (6 luminal B1, 2 luminal B2, 2 luminal A), were enrolled into the study, between January 23, 2015 and August 22, 2016. The mean age was 34.6 ± 6...

Reconstructing the genomes of bilaterian ancestors is central to our understanding of animal evolution, where knowledge from ancient and/or slow-evolving bilaterian lineages is critical. Here we report a high-quality, chromosome-anchored reference genome for the scallop Patinopecten yessoensis, a bivalve mollusc that has a slow-evolving genome with many ancestral features. Chromosome-based macrosynteny analysis reveals a striking correspondence between the 19 scallop chromosomes and the 17 presumed ancestral bilaterian linkage groups at a level of conservation previously unseen, suggesting that the scallop may have a karyotype close to that of the bilaterian ancestor...

In this Letter, we report a 1064 nm continuous wave Nd:YAG planar waveguide laser with an output power of 1544 W based on the structure of the master oscillator power amplification. A fiber laser is used as the master oscillator, and diode laser arrays are used as the pump source of the waveguide laser amplifier. The dimension of the waveguide is 1  mm (T)×10  mm (W)×60  mm (L), and the dual end oblique pumping is adopted with different angles. After a single-pass amplification, the power is scaled from 323 to 1544 W with the pump power of 2480 W, leading to an optical-to-optical efficiency of 49%...

Rheumatoid arthritis (RA) is a chronic systemic disorder characterized by the development through angiogenesis, which is dependent on endothelial cell activation, migration and proliferation and CCL21 plays an important role in this pathology. Currently, CCL21 gene polymorphism studies on rheumatoid arthritis are scarce and the results are diverse. This meta-analysis was performed to determine if CCL21 gene polymorphisms correlate with the risk of developing RA. Association reports for the relationship between CCL21 polymorphisms and RA were identified from PubMed, Cochrane Library, Embase, SCIELO, CNKI and Wanfang databases on March 22, 2017...

Salidroside, a major active ingredient isolated from Rhodiola rosea, has a long application in Chinese medical history. It has widely demonstrated effects on fatigue, psychological stress, and depression and exhibits potential antihypoxia activity. Emerging evidence shows that hypoxia is an important independent risk factor for erectile dysfunction (ED). The aim of this study was to clarify the effect of salidroside on hypoxia-induced phenotypic transformation of corpus cavernosum smooth muscle cells (CCSMCs)...

All-color subwavelength output of lasers was demonstrated in a rationally designed organic microdisk/silver nanowire heterostruc-tures. The dye-doped flexible microdisks served as the wavelength tunable whispering-gallery-mode (WGM) lasers with low lasing thresholds, while the silver nanowires supported the output of the lasing mode as subwavelength coherent light sources. The wave-length of the outcoupled laser was tuned over the full visible spec-trum scope owing to the flexibility of the microdisks and their compatibility with various organic laser dyes...

Tumor suppressor genes (TSGs) are frequently involved in the pathogenesis of hepatocellular carcinoma (HCC). The epigenetic and genetic alterations of a novel TSG‑protocadherin 9 (PCDH9) and its functions in the pathogenesis of HCC were investigated. The methylation status of the PCDH9 promoter was quantitatively analyzed, and the PCDH9 expression was analyzed in HCC cell lines treated with 5‑azacytidine. The effects of PCDH9 re‑expression and knockdown on growth, proliferation and tumorigenic potential were determined...

One-dimensional anodic TiO2 nanotube arrays hold great potential as photoelectrochemical sensor for the determination of chemical oxygen demand (COD). In this work, we report a warm synthesis of modified TiO2 nanotube arrays with enhanced photoelectrochemical determination performance. Herein, a bismuth-based semiconductor (-Bi2Mo3O12) was introduced to TiO2 nanotube arrays by sequential chemical bath deposition at room temperature. The structures, elemental compositions and morphologies of the products were investigated by X-ray diffraction, X-ray photoelectron spectroscopy, and field-emission scanning electron microscopy, respectively...

The study was designed to investigate whether the hamilton rating scale for depression (24-items) (HAM-D24) can be used to predict the diabetic microvascular complications in type 2 diabetes mellitus (T2DM) patients. 288 hospitalized patients with T2DM were enrolled. Their diabetic microvascular complications including diabetic nephropathy, diabetic retinopathy, diabetic peripheral neuropathy and diabetic foot as well as demographic, clinical data, blood samples and echocardiography were documented. All the enrolled patients received HAM-D24 evaluation...

Platelet aggregation and inflammation are both implicated in coronary artery disease (CAD). Thrombin induced platelet-fibrin clot strength (MAThrombin) measured by thrombelastography (TEG) has been proved to be a novel marker of platelet aggregation. The aim of this study was to investigate the correlation of MAThrombin to platelet volume indices (PVIs) or to inflammatory markers in different types of CAD. 206 patients with different types of CAD were enrolled. MAThrombin, PVIs, including mean platelet volume (MPV), platelet distribution width (PDW), and platelet-large cell ratio (P-LCR) as well as inflammatory markers, including high-sensitivity C-reactive protein (hs-CRP) and fibrinogen (Fbg) were measured...

BACKGROUND: Gastric cancer rarely metastasizes to the oral cavity, especially to gingiva. Only 18 cases have been reported worldwide to date. This paper herein presents the nineteenth case of gingival metastasis from gastric cancer. CASE PRESENTATION: A 75-year-old man who underwent a radical gastrectomy for gastric adenocarcinoma was admitted to clinical oncology center for gingival mass which was originally diagnosed as epulis. The subsequent positron emission tomography-computed tomography (PET-CT) and histopathological examination revealed a gingival metastatic adenocarcinoma originated from gastric carcinoma...
