In this work, carbon nanosphere (CNS)-based fluorescence "turn off/on" aptasensor was developed for targeted detection of breast cancer cell MCF-7 by conjugation with FAM (a dye)-labeled mucin1 (MUC1) aptamer P0 (P0-FAM), which can recognize MUC1 protein overexpressed on the surface of MCF-7. Different from other carbon based fluorescence quenching materials, CNSs prepared by the carbonization of glucose not only have the high fluorescence quenching efficiency (98.8%), but also possess negligible cytotoxicity (in the concentration range of 0-1 mg/mL, which is 10 times higher than that of traditional carbon nanotubes or graphene oxide (0-100 µg/mL))...

We describe a highly sensitive fluorescence biosensor incorporating polydopamine nanotubes (PDNTs) based on the mechanism of exonuclease III (Exo III) assisted signal amplification for the determination of Hg2+ in aqueous solution. Fluorescent probes of FAM labeled ssDNA (FAM-ssDNA) adsorbed on the PDNTs act as an efficient quencher. In the presence of Hg2+, the FAM-ssDNA can bind to Hg2+ to form double stranded DNA (dsDNA) via the formation of T-Hg2+-T base pairs. Then, the dsDNA was removed from the surface of the PDNTs to restore the fluorescence...

miR-34a is a master tumor suppressor playing a key role in the several signalling mechanisms involved in cancer. However its delivery to the cancer cells is the bottleneck in its clinical translation. Herein we report cationic amphiphilic copolymers grafted with cholesterol (chol), N,N-dimethyldipropylenetriamine (cation chain) and 4-(2-aminoethyl)morpholine (morph) for miR-34a delivery. The copolymer interacts with miR-34a at low N/P ratios (~2/1) to form nanoplexes of size ~108 nm and a zeta potential ~ +39 mV...

PURPOSE: Many types of dosimeters are used to measure radiation dose and calibrate radiotherapy equipment, but none directly measure the biological effect of this dose. The purpose here is to create a dosimeter that can measure the probability of double-strand breaks (DSB) for DNA, which is directly related to the biological effect of radiation. METHODS: A DNA dosimeter, consisting of magnetic streptavidin beads attached to 4 kilobase pair DNA strands labeled with biotin and fluorescein amidite (FAM) on opposing ends, was suspended in phosphate-buffered saline (PBS)...

Over the last ten years, active surveillance (AS) has become increasingly utilized for patients with low-risk prostate cancer. Appropriately selected AS patients have a 10-year prostate cancer-specific mortality (PCSM) approaching 99%. Therefore, some institutions have expanded the inclusion criteria for AS to avoid the unnecessary morbidity associated with overtreatment. In this review, data from several high-quality studies were compiled to demonstrate how AS inclusion criteria may be safely expanded. Although AS criteria, data reporting, and statistical methods were heterogeneous across studies, several findings were consistent and provided insight for clinical practice...

Alzheimer's disease (AD) considered as the third health "killer" has seriously threatened the health of the elderly. However, the modern diagnostic strategies of AD present several disadvantages: the low accuracy and specificity resulting in some false-negative diagnoses, and the poor sensitivity leading to a delayed treatment. In view of this situation, a enzyme-free and target-triggered signal amplification strategy, based on graphene oxide (GO) and entropy-driven strand displacement reaction (ESDR) principle, was proposed...

In this study, a novel aptamer - based fluorescence bio-sensor (aptamer-AuNps) was developed for chiral recognition of arginine (Arg) enantiomers based on aptamer and gold nanoparticles (AuNps). Carboxyfluorescein (FAM) labeled aptamers (Apt) were absorbed on AuNps and their fluorescence intensity could be significantly quenched by AuNps based on fluorescence resonance energy transfer (FRET). Once d-Arg or l-Arg were added into the above solution, the aptamer specifically bind to Arg enantiomers and released from AuNps, so the fluorescence intensity of d-Arg system and l-Arg system were all enhanced...

The base-quenched probe method for detecting single nucleotide polymorphisms (SNPs) relies on real-time PCR and melting-curve analysis, which might require only one pair of primers and one probe. At present, it has been successfully applied to detect SNPs of multiple genes. However, the mechanism of the base-quenched probe method remains unclear. Therefore, we investigated the possible mechanism of fluorescence quenching by DNA bases in aqueous solution using spectroscopic techniques. It showed that the possible mechanism might be photo-induced electron transfer...

A fluorometric aptamer-based assay was developed for ultrasensitive and selective determination of the neonicotinoid insecticide acetamiprid. The method is based on the use of an aptamer against acetamiprid, multiple complementary strands (CSs), and gold nanoparticles (AuNPs). It is found that by using different CSs, the sensitivity and selectivity of the method is enhanced. On addition of acetamiprid to the aptamer, they will bind to each other and CS1-fluorescein (FAM)-labeled CS2 (as a dsDNA) will be formed...

BACKGROUND: Cardiac size measurements require indexing to body size. Allometric indexing has been investigated in Caucasian populations but a range of different values for the so-called allometric power exponent (b) have been proposed, with uncertainty as to whether allometry offers clinical utility above body surface area (BSA)-based indexing. We derived optimal values forbin normal echocardiograms and validated them externally in cardiac patients.Methods and Results:Values forbwere derived in healthy adult Chinese males (n=1,541), with optimalbfor left ventricular mass (LVM) of 1...

BACKGROUND: Epidemiological and experimental literature indicates that the risk of breast cancer incidence is strongly linked to hormone-dependent factors, including reproductive history and obesity. However, the molecular mechanisms underlying the association between these factors and breast cancer risk are poorly understood. The aim of this study, therefore, was to determine whether obesity and reproductive history are associated with expression levels of two breast cancer-related long non-coding RNAs (lncRNAs), namely ZFAS1 and SRA1 in cancer-free breast tissues of women...

In this paper, we redescribe Ptilophora plumigera variabilis Hartig, 1968 and raise it to species rank. Furthermore we describe Ptilophora nebrodensis sp. n. from Sicily, as the third European species belonging to the genus Ptilophora Stephens, 1828. These two species are allopatric vicariants of Ptilophora plumigera (Denis Schiffermüller, 1775) respectively in Apennine Italy and Sicily. We present the differential features mainly concerning the morphology of genitalia and molecular data. Ptilophora variabilis shows a scattered distribution, generally very localized, whereas P...
