BACKGROUND Non-linear dielectric spectroscopy (NLDS) of microorganism was characterized by the generation of harmonics in the polarization current when a microorganism suspension was exposed to a sinusoidal electric field. The biological nonlinear response initially described was not well verified by other authors and the results were susceptible to ambiguous interpretation. In this paper NLDS ...

INTRODUCTION Chromosomal changes are widespread in the vast majority of colon carcinomas and aneuploidy is an established prognostic factor. However, this knowledge so far has no influence on tumor classification. We reported a morphology-based classification scheme, the core classification, that correlates with DNA ploidy. In particular, tripolar mitoses were identified as surrogate markers of...

Transcutaneous electrical nerve stimulation (TENS) is an analgesia inducing method with increasing applications in clinical procedures. In this study we tried to evaluate the role of the adrenergic system and its different adrenoceptor subtypes in TENS-induced analgesia. Two types of low and high frequency electrical stimuli were used in rats through needle electrodes, inserted at the base ...

The properties of cyclic structures (toroidal oscillators) based on classical tripolar (colour) fields are discussed, in particular, those of a cyclic structure formed of three colour singlets spinning around a ring-closed axis. It is shown that the helicity and handedness of this structure can be related to the quantum properties of the electron. The symmetry of this structure corresponds to t...

Dislocation of a total hip replacement (THR) is common following total hip arthroplasty (THA). When nonoperative management fails to maintain reduction, revision surgery is considered. The use of constrained acetabular liners has been extensively described. Complete removal of the old cement mantle during revision THA can be challenging and is associated with significant complications. Cement-i...
