Fatigue is one of the most distressful problems faced by terminally ill cancer patients, but few studies have explored fatigue experiences in this population. The purpose of this descriptive correlational study was to examine fatigue status and its related factors in terminally ill cancer patients in an institutionalized hospice in Northern Taiwan.

The aim of this study was to investigate a nursing staff’s knowledge of the Natural Death Act before and after an educational intervention. This was a quasi-experimental designed study. Questionnaires were sent to 135 nurses in a medical center who volunteered to participate in the educational program. Demographic data and knowledge of the Natural Death Act(More)
We aimed to evaluate the palliative care quality for terminal cancer patients as a reference for prospective service improvements. A prospective study was conducted to analyze the quality audit data collected from 1,476 samples in one medical center’s palliative care unit. Lai’s modified version of the support team assessment schedule was utilized for(More)
Förster resonance energy transfer (FRET) may be regarded as a "smart" technology in the design of fluorescence probes for biological sensing and imaging. Recently, a variety of nanoparticles that include quantum dots, gold nanoparticles, polymer, mesoporous silica nanoparticles and upconversion nanoparticles have been employed to modulate FRET.

Photodynamic therapy (PDT) typically involves oxygen (O2 ) consumption and therefore suffers from greatly limited anticancer therapeutic efficacy in tumor hypoxia. Here, it is reported for the first time that amine-terminated, PAMAM dendrimer-encapsulated gold nanoclusters (AuNCs-NH2 ) can produce O2 for PDT via their intrinsic catalase-like activity. The(More)
We report results of two-color resonant four-wave mixing experiments on highly predissociated levels of the methylthio (or thiomethoxy) radical CH3S in its first excited electronic state A 2A1. Following photolysis of jet-cooled dimethyl disulfide at 248 nm, the spectra were measured with a hole-burning scheme in which the probe laser excited specific(More)
The excited-state dynamics of phenylvinylacetylene (1-phenyl-1-buten-3-yne, PVA) have been studied using laser-induced fluorescence spectroscopy, ultraviolet depletion spectroscopy, and the newly developed method of ultraviolet population transfer spectroscopy. Both isomers of PVA (E and Z) show a substantial loss in fluorescence intensity as a function of(More)
Near-pure samples of (E)-phenylvinylacetylene ((E)-PVA) and (Z)-phenylvinylacetylene ((Z)-PVA) were synthesized, and their ultraviolet spectroscopy was studied under jet-cooled conditions. The fluorescence excitation and UV-UV holeburning (UVHB) spectra of both isomers were recorded. The S0-S1 origin of (E)-PVA occurs at 33,578 cm(-1), whereas that for(More)
