The purpose of this study was to examine the linearity of summation of the forces produced by the stimulation of different combinations of type identified motor units (MUs) in the cat peroneus longus muscle (PL) under isometric conditions. The muscle was fixed at its twitch optimal length, and the tension produced by the single MU was recorded during 24- and 72-Hz stimulation. The summation ana...

A computer-assisted method of isolating single motor units (MUs) by multiple point stimulation (MPS) of peripheral nerves is described. MPS was used to isolate 10-30 single MUs from thenar and hypothenar muscles of normal subjects and patients with entrapment neuropathies, with the original purpose of obtaining a more representative mean motor unit potential for estimating the number of MUs in ...

A novel gammaretrovirus, xenotropic murine leukemia virus-related virus (XMRV), has been identified in patients with prostate cancer and in patients with chronic fatigue syndromes. Standard Mus musculus laboratory mice lack a functional XPR1 receptor for XMRV and are therefore not a suitable model for the virus. In contrast, Gairdner's shrew-mice (Mus pahari) do express functional XPR1. To dete...

Medically unexplained symptoms (MUS) remain recalcitrant to the medical profession, proving less suitable for homogenic treatment with respect to their aetiology, taxonomy and diagnosis. While the majority of existing medical research methods are designed for large scale population data and sufficiently homogenous groups, MUS are characterised by their heterogenic and complex nature. As a resul...

OBJECTIVE We compared the outcomes of the midurethral sling (MUS) with and without concomitant prolapse repair. METHODS We retrospectively reviewed the outcomes of 203 women who underwent MUS at Severance Hospital from January 2009 to April 2012 with and without concomitant prolapse repair. Patients completed the urogenital distress inventory questionnaire preoperatively and postoperatively. ...

Stress urinary incontinence (SUI) has always been a major health issue for women. With the progression of technology and surgical techniques, mid urethral slings (MUS) used in both transvaginal and transobturator routes have become the gold standard in the treatment of SUI. There is ample short to mid-term data confirming the efficacy and safety in using MUS in treating SUI in women. However, l...

Efficient algorithms for extracting minimally unsatisfiable subformulas (MUSes) of Boolean formulas find a wide range of applications in the analysis of systems, e.g., hardware and software bounded model checking. In this paper we study the applicability of preprocessing techniques for Boolean satisfiability (SAT) in the context of MUS extraction. Preprocessing has proven to be extremely import...

This paper tackles the problem of deciding whether a given clause belongs to some minimally unsatisfiable subset (MUS) of a formula, where the formula is in conjunctive normal form (CNF) and unsatisfiable. Deciding MUS-membership helps the understanding of why a formula is unsatisfiable. If a clause does not belong to any MUS, then removing it will certainly not contribute to restoring the form...

Simultaneous recordings of action potentials (APs) of multiple single motor units (MUs) were obtained in brachialis and biceps (caput breve) muscles during si­ nusoidally modulated isometric contractions of elbow flexor muscles and during sinusoidal flexion/extension movements in the elbow against a preload in the exten­ sion direction. The results show that MUs typically fire in one short burs...

Treatment of a cell line derived from the Asian feral mouse Mus caroli with 5-bromodeoxyuridine induces an infectious, xentropic type C virus. This virus shares strongly cross-reactive reverse transcriptase (RNA-dependent DNA polymerase) and p30 antigens and crossinterferes with type C viruses isolated from a woolly monkey (SSAV) and gibbon apes (GALV). By similar criteria, the caroli virus is ...
