Tongue dysfunction is a hallmark of many human clinical disorders, yet we lack even a rudimentary understanding of tongue neural control. Here, the location and contractile properties of intrinsic longitudinal motor units (MUs) of the rat tongue body are described to provide a foundation for developing and testing theories of tongue motor control. One hundred and sixty-five MUs were studied by ...

BACKGROUND Clinical studies have shown that Medically Unexplained Symptoms (MUS) are related to common mental disorders. It is unknown how often common mental disorders occur in subjects who have explained physical symptoms (PHY), MUS or both, in the general population, what the incidence rates are, and whether there is a difference between PHY and MUS in this respect. AIM To study the preval...

A 305 base pair DNA sequence isolated from the Y chromosome of the inbred mouse strain C57BL/10 was used to investigate the pattern and tempo of evolution of Y chromosome DNA sequences for five species in the subgenus Mus, including Mus spretus, Mus hortulanus, Mus abbotti, Mus musculus and Mus domesticus. Variation in hybridization patterns between species was characterized by differences in f...

Thirteen X-linked mutants have been isolated in Drosophila melanogaster which render male and homozygous female larvae sensitive to the mutagen methyl methanesulfonate. Their characterization and preliminary assignment to functional groups is described. Four of these mutants are alleles of mei-41 (Baker and Carpenter 1972). Like previously isolated alleles of this locus, these mutants reduce fe...

Southern blot hybridization analysis of genomic DNAs digested with restriction endonuclease EcoR I and Ava II from Mus musculus domesticus, Mus booduga and Mus terricolor with a cloned repetitive DNA fragment of Mus booduga as a probe showed difference in restriction pattern of this DNA in these three species. Further Southern analysis of the BamH I digested genomic DNAs from these species hybr...

Muscle force is due to the cumulative effect of repetitively contracting motor units (MUs). To simulate the contribution of each MU to whole muscle force, an approach implemented in a novel computer program is proposed. The individual contraction of an MU (the twitch) is modeled by a 6-parameter analytical function previously proposed; the force of one MU is a sum of its contractions due to an ...

Background. The prevalence of medically unexplained symptoms (MUSs) in primary care is about 10-15%. The definition of MUS is descriptive and there are no specific diagnostic criteria for MUS in primary care. Furthermore, a general practitioner's (GP's) categorisation of patients with MUS shows large variation. The aim of the present study is to investigate how GPs employ the definition of MUS ...

OBJECTIVE Potential Reduced Exposure tobacco Products (PREP) are intended to lower human exposure to toxic constituents of tobacco smoke, but rigorous clinical evaluations are required to assess such claims. The present study assessed human smoking behavior and short-term exposure to a new carbon-filtered PREP, Marlboro UltraSmooth (MUS). Two MUS prototypes with filter carbon loads of 120 and 1...

BACKGROUND Medically Unexplained Symptoms (MUS) are frequently encountered in general practice. However, little is known whether MUS affects labor market participation. We investigated the prospective association between MUS at baseline and risk of long-term sickness absence (LTSA), unemployment, and disability pensioning in a 5-year-follow-up study. METHODS In the Danish Work Environment Coh...

Based on the integral theory, tension-free placement of a mid-urethral sling (MUS) for female stress urinary incontinence (SUI) has gained substantial popularity owing to the ease of the procedure and its effectiveness. Published series with long-term follow-up show continence rates after the MUS procedure ranging from 70% to 80%. Complication rates after MUS procedures are usually low. This re...
