In 1998, formal diagnostic criteria were proposed for a syndrome of cancer-related fatigue. These criteria were intended to facilitate the study of cancer-related fatigue and the development of appropriate interventions MDV3100 chemical structure to ameliorate fatigue. Although the criteria have been widely cited, to date, there has been no

systematic review of research using the criteria that might inform their continued use or revision. Methods We conducted a systematic review of the literature reporting results based on use of the diagnostic criteria. Data were analyzed to characterize the reliability and validity of the criteria and to describe the prevalence of cancer-related fatigue. Results We identified nine eligible studies. The purpose of the majority of the studies was to estimate the prevalence see more of cancer-related fatigue; there was considerable variability with respect to design and nature of the samples included. Although few studies examined reliability of the criteria, findings reported support their reliability. The validity of the criteria judged relative to established measures of fatigue and related constructs appears to be strong. Prevalence rates

for cancer-related fatigue based on the diagnostic criteria vary widely, reflecting a lack of consistency in how the criteria have been applied. Conclusions As a comprehensive approach to diagnosing cancer-related fatigue, the diagnostic criteria have received relatively scant attention by the clinical research community. Our findings suggest the need for research aimed at revising the criteria, enhancing their usefulness, and promoting their more widespread use. Copyright (c) 2012 John Wiley & Sons, Ltd.”
“Composites of polyvinylidene fluoride (PVDF) filled with metallic particles of nickel (Ni) were prepared via a blending and hot-molding LB-100 nmr technique.

Rescaled temperature dependence of electric and dielectric behaviors of Ni/PVDF composites were studied at wide content ranges. Results show that there is significant positive temperature coefficient effect and giant dielectric constant as the concentration of Ni is near the percolation threshold. The nonuniform distribution of filler particles in PVDF host is observed from the scanning electron microscope micrograph since they are aggregated in amorphous regions of PVDF and form a network of conducting chains. Two relaxation peak regions of dielectric constant are observed from -10 to 40 degrees C and from 100 to 150 degrees C, which can be attributed to the contribution of polar effect of PVDF. The percolation theory, the thermal expansion model, and the simple concept of polarization in the capacitors are employed to explain these experimental results.”
“The mouse preadipocyte 3T3-L1 line is the most useful cell line for the study of adipocytes. Adipocytes secrete adipocytokines, and abnormal adipocytokine production can cause the metabolic syndrome.
