Signal on-off ratiometric electrochemical sensor coupled with a molecularly imprinted polymer for the detection of carbendazim.

A stable ratiometric electrochemical sensor is introduced for the selective detection of carbendazim (CBD). Specifically, the proposed sensor employs a Co@MoC bimetallic nanomaterial as the glassy carbon electrode substrate and a layer of molecularly imprinted polymer (MIP) was in situ fabricated on glassy carbon electrode by electropolymerization, with o-aminophenol as the functional monomer and CBD acting as template. A ratiometric MIP sensor was constructed by adding ferrocene (Fc) internal reference directly to the sample solution.

Clinicopathological, Radiological, and Molecular Features of Primary Lung Adenocarcinoma with Morule-Like Components.

Background: Morule-like component (MLC) was a rare structure in primary lung adenocarcinoma. We aimed to reveal the clinicopathological, radiological, immunohistochemical, and molecular features of lung adenocarcinoma with MLCs.

Methods: Twenty lung adenocarcinomas with MLCs were collected, and computed tomographic and histological documents were reviewed.

[Effects of miRNA-1,miRNA-21 in plasma on in-stent restenosis in patients with coronary heart disease and diabetes mellitus after percutaneous coronary intervention].

Objective: To observe the expression differences of the plasma miRNA-1, miRNA-21 between patients with coronary heart disease (CHD) and without coronary artery lesions, between patients with in-stent restenosis (ISR) and none in-stent restenosis (NISR), and to study their predictive value for ISR occurred after percutaneous coronary intervention (PCI) in patients with CHD and diabetes mellitus (DM).

Methods: The selected subjects were divided into CHD group in which patients were implemented stenting (=187), and control group in which patients were without coronary artery lesions (=195). According to the guidelines, the control group was divided into normal group (=150), simple-DM group (=45); the CHD group was divided into simple-CHD group (=119) and CHD-DM group (=68), the CHD group was also divided into ISR group (=48), NISR group (=139), and the ISR group was divided into simple-ISR group (=26) and ISR-DM group (=22) again.

Outcome of cervicocranial artery dissection with different treatments: a systematic review and meta-analysis.

Objective: The purpose of this meta-analysis is to compare clinical outcomes between endovascular treatment and conservative treatment for cervicocranial artery dissection.

Methods: Medline, Embase, and Cochrane Library databases were searched for studies comparing endovascular treatment versus conservative treatment for cervicocranial artery dissection patients. The period searched was from November 1994 to March 2013.

[Characteristics and influencing factors of carbonaceous aerosols in PM2.5 in Shanghai, China].

Organic carbon (OC) and elemental carbon (EC) in PM2.5 samples collected in urban (Xujiahui) and industrial (Baoshan) areas in Shanghai during 2007-2008 were analyzed with a DRI carbon analyzer using IMPROVE-TOR protocol. The results showed that the seasonal average concentrations of OC and EC were highest in the winter and lowest in the summer.
