Ethical questions concerning problems of conducting delivery of enormously immature foetuses are subjected to intensive discussion and call for a permanent and wide consideration with the participation of all specialists, who are involved in the problem. The discussions have persisted over tens of years and became intensive particularly at the moment of defining the foetus viability. In the pre...

Aterrorist nuclear detonation of 10 kilotons would have catastrophic physical, medical, and psychological consequences and could be accomplished with a device in a small truck. Tens of thousands of injured and ill survivors and uninjured, concerned citizens would require medical care or at least an assessment and instructions. In proximity to the incident location, there would be a huge imbalan...

A major challenge in proteomics is the absolute accurate quantification of large numbers of proteins. QconCATs, artificial proteins that are concatenations of multiple standard peptides, are well established as an efficient means to generate standards for proteome quantification. Previously, QconCATs have been expressed in bacteria, but we now describe QconCAT expression in a robust, cell-free ...

The microscopic and macroscopic dynamics of random networks is investigated in the strong-dilution limit (i.e., for sparse networks). By simulating chaotic maps, Stuart-Landau oscillators, and leaky integrate-and-fire neurons, we show that a finite connectivity (of the order of a few tens) is able to sustain a nontrivial collective dynamics even in the thermodynamic limit. Although the network ...

Using an outer rotation curve of the Galaxy, we explore the galactic constants and the mass of the Galaxy. We show that Θ0 of 200 km s −1 is more favorable than the IAU standard value of 220 km s, and also show that if Θ0 is smaller than 207 km s −1 the rotation curve beyond 2R0 is declining in Keplerian fashion. In the case of Θ0= 200 km s −1 and R0= 7.6 kpc, the total mass and the extent of t...

Because bacterial recombination involves the occasional transfer of small DNA fragments between strains, different sets of niche-specific genes may be maintained in populations that freely recombine at other loci. Therefore, genetic isolation may be established at different times for different chromosomal regions during speciation as recombination at niche-specific genes is curtailed. To test t...

The influence of naloxone on the effects of high frequency transcutaneous electrical nerve stimulation in angina pectoris induced by atrial pacing was studied in 11 patients with severe coronary artery disease. The patients were catheterised and treated with transcutaneous electrical nerve stimulation on two occasions, double blind and in random order, with a single intravenous dose of saline o...

BACKGROUND Transcutaneous electrical nerve stimulation and interferential current have been widely used in clinical practice. However, a systematic review comparing their effects on pain relief has not yet been performed. OBJECTIVES To investigate the effects of transcutaneous electrical nerve stimulation and interferential current on acute and chronic pain. METHODS We use Pubmed, Embase, L...

INTRODUCTION Transcutaneous electrical nerve stimulation is a possible adjunctive therapy to pharmacological treatment for controlling pain after total knee arthroplasty. However, the results are controversial. A systematic review and meta-analysis was conducted to explore the effect of transcutaneous electrical nerve stimulation on patients with total knee arthroplasty. METHODS PubMed, Embas...

Transcutaneous electrical nerve stimulation has been proposed as a nonoperative treatment for osteoarthritis. The purpose of this study was to evaluate the outcomes of a novel transcutaneous electrical nerve stimulation device compared with those of other standard nonoperative modalities for the treatment of osteoarthritis of the knee.
