Label-free microfiber biosensor for ultrahigh sensitivity detection of TNF-α protein.

Rapid detection of low concentrations of tumor necrosis factor-α (TNF-α) plays an important role in medical diagnostics. This study proposed a fast, label-free single mode-tapered no core-single mode (STNCS) microfiber structure for the ultra-low concentration of TNF-α detection. The experimental results show that the proposed microfiber biosensors have good spectral stability (0.

Fan-ring interpolation method applied to the panorama unwrapping of the deep-hole parts.

Image interpolation is a critical step in panoramic image unwrapping studies. Information calculated in the Cartesian coordinates, although broadly applied, applies to operation between rectangles that will destroy the compressed depth information. The polar coordinates, in contrast, can store depth information by handing between rectangle and circle to obtain more true images.

The emission quenching of upconversion nanoparticles coated with amorphous silica by fluorescence resonance energy transfer: A mercury-sensing nanosensor excited by near-infrared radiation.

In this paper, a rhodamine derivative was synthesized as a probe for Hg(II) detection. Its spectral response and sensing mechanism towards Hg(II) were discussed carefully. It was found that its absorption and emission were increased by Hg(II), via a direct bonding stoichiometry of 1:1.

Factors influencing quality of life of elderly people with dementia and care implications: A systematic review.

Background: Identifying factors associated with Quality of Life (QoL) of elderly people with dementia could contribute to finding pathways to improve QoL for elderly people in dementia.

Aim: This paper systematically reviews all possible factors that influence QoL of elderly people with dementia, identifies how these factors are different by different stages of dementia and living settings, and explores how the influencing factors could be perceive differently by elderly people with dementia, family members, and caregivers.

Method: PubMed, PsycINFO, Web of Science and DelphiS searches from 2000 to 2015 and hand searches of publication lists, reference lists and citations were used to identify primary studies on 'quality of life' and 'dementia' elderly people.
