Nesting behavior was found to differ for animals of five different inbred strains of Mus musculus reared in the same environment, indicating heritable differences in level of nesting by Mus. For two separate crosses, hybrid animals built larger nests than did animals of the inbred parental strains. In addition, .from data of one of the crosses and derived generations, a very low heritability of...

Mouse strains show polymorphisms in the amino acid sequences of serum amyloid A 1 (SAA1) and serum amyloid A 2 (SAA2). Major laboratory mouse strains are classified based on the sequence as carrying the A haplotype (e.g., BALB/c) or B haplotype (e.g., SJL/J) of the Saa1 and Saa2 gene unit. We attempted to elucidate the diversity of the mouse Saa1 and Saa2 family genes at the nucleotide sequence...

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...

OBJECTIVE Medically unexplained symptoms (MUS) are commonly encountered in medical practice. In psychiatry, they are classified mostly as Somatoform Disorders and are often associated with anxiety and depression. The literature suggests that, in some cases, MUS may be ascribed to Somatoform Disorders when, fact, they are "organic" syndromes that are misdiagnosed. In developing countries, with f...

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...

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. ...

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 ...

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...
