Silica optical fiber integrated with two-dimensional materials: towards opto-electro-mechanical technology.

In recent years, the integration of graphene and related two-dimensional (2D) materials in optical fibers have stimulated significant advances in all-fiber photonics and optoelectronics. The conventional passive silica fiber devices with 2D materials are empowered for enhancing light-matter interactions and are applied for manipulating light beams in respect of their polarization, phase, intensity and frequency, and even realizing the active photo-electric conversion and electro-optic modulation, which paves a new route to the integrated multifunctional all-fiber optoelectronic system. This article reviews the fast-progress field of hybrid 2D-materials-optical-fiber for the opto-electro-mechanical devices.

A Flexible Wireless Dielectric Sensor for Noninvasive Fluid Monitoring.

A flexible wireless dielectric sensor is presented here for noninvasively monitoring the permittivity and conductivity of fluids, based on resistor-inductor-capacitor (RLC) resonant circuit and capacitively coupled contactless conductivity detection (CD) technique. The RLC sensor consists of one single-turn inductor and one interdigital capacitor. The resonant frequency of the device is sensitive to the surrounding environment, thanks to the electric field leaked out between the interdigital capacitor electrodes.

Effects of Rad51 on survival of A549 cells.

Rad51, a key factor in the homologous recombination pathway for the DNA double-strand break repair, plays a vital role in genesis of non-small-cell lung cancer (NSCLC). In recent years, more and more studies indicate that high expression of Rad51 is of great relevance to resistance of NSCLC to chemotherapeutic agents and ionizing radiation. However, the underlying molecular mechanisms are poorly understood.

[Diagnostic implications of atypical squamous cells of unknown significance with abnormal DNA ploidy for early cervical lesions].

Objective: To investigate the clinical significance of atypical squamous cells of unknown significance (ASCUS) with abnormal DNA ploidy in the early diagnosis of cervical lesions.

Methods: Eight thousand four hundred and forty-eight patients were included in this study and all had DNA quantitative analysis and cervical liquid-based cytology. Among 1041 cases with DNA aneuploidy and/or abnormal cervical liquid-based cytology and additional cervical biopsy, histological review was performed in 247 ASCUS cases with abnormal DNA ploidy.

[Expression of HER2/neu in meningiomas: an immunohistochemistry and fluorescence in situ hybridization study].

Objective: To investigate the expression of HER2/neu, Ki-67 and TK1 protein in meningiomas in correlation with tumor grades and recurrence.

Methods: Twenty cases of each of the following types of meningiomas were selected for the study, namely: the benign non-recurrent, recurrent benign, atypical and malignant, according to the World Health Organization (WHO) histological classification of nervous system, 2007. Immunohistochemistry study for HER2/neu, Ki-67 and TK1 protein was performed.
