Concordance analysis between Human Papillomavirus genotyping assay and PCR-reverse spot hybridization for the detection of Human Papillomavirus infection.

Human papillomavirus (HPV), the predominant viral infection affecting the anogenital tract, is closely linked to the development of intraepithelial neoplasia and malignancies in the cervix and other anal regions. Currently, 15 high-risk HPVs (HR-HPVs) and 3 potential HR-HPV types have been recognized as contributors to cervical cancer. Consequently, it is imperative to conduct HR-HPV screening using suitable tests in order to identify precancerous lesions and prevent the development of cancer.

Chinese association of ultrasound in medicine and engineering, superficial organs and peripheral vessels committee expert consensus on clinical frequently asked questions in breast ultrasonography, June 2018.

Ultrasonography, the preferred imaging modality for breast diseases, has merits such as absence of radiation, high diagnostic accuracy, and convenience for follow-up, thus playing an important role in clinical diagnosis and management. The American College of Radiology (ACR) proposed Breast Imaging-Reporting and Data System (BI-RADS ) and has updated for several times. Gradually, the BI-RADS has been accepted and adopted by ultrasound physicians at all levels of hospitals in China, and it has played a certain role in improving the diagnostic level of breast ultrasound in China.

How to determine an optimal threshold to classify real-time crash-prone traffic conditions?

One of the proactive approaches in reducing traffic crashes is to identify hazardous traffic conditions that may lead to a traffic crash, known as real-time crash prediction. Threshold selection is one of the essential steps of real-time crash prediction. And it provides the cut-off point for the posterior probability which is used to separate potential crash warnings against normal traffic conditions, after the outcome of the probability of a crash occurring given a specific traffic condition on the basis of crash risk evaluation models.

Regulation of matriptase and HAI-1 system, a novel therapeutic target in human endometrial cancer cells.

The effects of specific and non-specific regulation of matriptase on endometrial cancer cells were investigated. Messenger ribonucleic acid (mRNA) and protein expression of matriptase and hepatocyte growth factor activator inhibitor-1 (HAI-1) in RL-952, HEC-1A, and HEC-1B endometrial cancer cells were detected by real-time quantitative PCR (RT-qPCR) and western blot. The cells were infected with lentivirus-mediated small-interfering RNA (siRNA) targeted on matriptase (MA-siRNA) or treated with different cisplatin (DDP) concentrations.

Decreasing the ratio of matriptase/HAI‑1 by downregulation of matriptase as a potential adjuvant therapy in ovarian cancer.

Tumor invasion and metastasis are complex biological processes. Matriptase and its endogenous inhibitor, hepatocyte growth factor activator inhibitor‑1 (HAI‑1) are involved in invasion and metastasis. To evaluate the ratio of matriptase/HAI‑1 and their potential therapeutic value in ovarian cancer, HO‑8910 human ovarian cancer cells and the homologous high‑metastatic HO‑8910PM cells were used as in vitro cellular models ovarian cancer.

Tailoring the Synergistic Bronsted-Lewis acidic effects in Heteropolyacid catalysts: Applied in Esterification and Transesterification Reactions.

In order to investigate the influences of Lewis metals on acidic properties and catalytic activities, a series of Keggin heteropolyacid (HPA) catalysts, HnPW11MO39 (M = Ti(IV), Cu(II), Al(III), Sn(IV), Fe(III), Cr(III), Zr(IV) and Zn(II); for Ti and Zr, the number of oxygen is 40), were prepared and applied in the esterification and transesterification reactions. Only those cations with moderate Lewis acidity had a higher impact. Ti Substituted HPA, H5PW11TiO40, posse lower acid content compared with Ti(x)H(3-4x)PW12O40 (Ti partial exchanged protons in saturated H3PW12O40), which demonstrated that the Lewis metal as an addenda atom (H5PW11TiO40) was less efficient than those as counter cations (Ti(x)H(3-4x)PW12O40).

Rhesus macaques develop metabolic syndrome with reversible vascular dysfunction responsive to pioglitazone.

Background: The metabolic syndrome (MetS) is a constellation of clinical features that include central obesity, hypertension, atherogenic dyslipidemia, and insulin resistance. However, the concept remains controversial; it has been debated whether MetS represents nothing more than simultaneous co-occurrence of individual risk factors or whether there are common shared pathophysiological mechanisms that link the individual components.

Methods And Results: To investigate the emergence of metabolic and cardiovascular components during the development of MetS, we identified MetS-predisposed animals (n=35) in a large population of rhesus macaques (Macaca mulatta, 12.

Light beam coupling between standard single mode fibers and highly nonlinear photonic crystal fibers based on the fused biconical tapering technique.

We propose and experimentally demonstrate light beam coupling between a single-mode fiber (SMF) and a highly nonlinear photonic crystal fiber (HN-PCF) based on the fused biconical tapering (FBT) technique. In our experiment, a standard SMF is pre-tapered to match its propagation constant to that of a HN-PCF. In order to remove the condensation in the air holes, the temperature is increased gradually to preheat the fibers.

Impacts of imperfect geometry structure on the nonlinear and chromatic dispersion properties of a microstructure fiber.

We numerically investigated the impacts of the imperfect geometry structure on the nonlinear and chromatic dispersion properties of a microstructure fiber (MF). The statistical results show that the imperfect geometry structure degrades the high nonlinearity and fluctuates the chromatic dispersion in a MF. Moreover, the smaller air holes and the larger pitch are more likely to maintain the properties of nonlinearity and chromatic dispersion.
