Basic empathy: Developing the concept of empathy from the ground up.

Empathy is a topic of continuous debate in the nursing literature. Many argue that empathy is indispensable to effective nursing practice. Yet others argue that nurses should rather rely on sympathy, compassion, or consolation.

Metaproteomics of Freshwater Microbial Communities.

Recent advances in metaproteomics have provided us a link between genomic expression and functional characterization of environmental microbial communities. Therefore, the large-scale identification of proteins expressed by environmental microbiomes allows an unprecedented view of their in situ metabolism and function. However, one of the main challenges in metaproteomics remains the lack of robust analytical pipelines.

Absorption, excretion, and retention of selenium from a high selenium yeast in men with a high intake of selenium.

Objective: The purpose of this study was to evaluate the pharmacokinetics of a single dose of Selenium (Se) from yeast given to humans with a habitual long-term daily intake at a supra-nutritional level.

Methods: Twelve healthy males with a daily supplemental intake of 300 microg Se as selenised yeast over 10 weeks were supplemented with a single dose of 327 microg as stable (77)Se incorporated into selenised yeast manufactured by the same standardised process (SelenoPrecise(R), Pharma Nord, Denmark).

Results: Absorption of Se from (77)Se-enriched yeast was 89+/-4% and the retention was 74+/-6%.

Limitations to systemic and locomotor limb muscle oxygen delivery and uptake during maximal exercise in humans.

Reductions in systemic and locomotor limb muscle blood flow and O2 delivery limit aerobic capacity in humans. To examine whether O2 delivery limits both aerobic power and capacity, we first measured systemic haemodynamics, O2 transport and O2 uptake during incremental and constant (372 +/- 11 W; 85% of peak power; mean +/- S.E.

SNP typing on the NanoChip electronic microarray.

We describe a single nucleotide polymorphism (SNP) typing protocol developed for the NanoChip electronic microarray. The NanoChip array consists of 100 electrodes covered by a thin hydrogel layer containing streptavidin. An electric currency can be applied to one, several, or all electrodes at the same time according to a loading protocol generated by the user.

Clinical intra- and interfamilial variability of cluster headache.

Our recent description of a 17- and 2-fold increased risk of cluster headache among first- and second-degree relatives, respectively, strongly suggests that cluster headache has a genetic cause. Eighteen families with familial occurrence of cluster headache according to the criteria of the International Headache Society were included. Clinical intra- and interfamilial variability of cluster headaches was analyzed in 44 cases (31 males and 13 females) from 18 families.

Oral cholecystography compared to cholescintigraphy for evaluation of cystic duct patency prior to ESWL treatment.

In a prospective, blinded study of 109 patients with cholecystolithiasis, oral cholecystography and 99Tcm-EHIDA cholescintigraphy were compared in terms of reliability for demonstrating cystic duct patency: one of the prerequisites for extracorporeal shock wave lithotripsy (ESWL) treatment of cholecystolithiasis. Patients with a positive result on one or both tests were regarded as having cystic duct patency. Patients with negative and uncertain result of both tests or one of each were regarded as having no cystic duct patency.
