BACKGROUND The development of animal models that approximate human frailty is necessary to facilitate etiologic and treatment-focused frailty research. The genetically altered IL-10(tm/tm) mouse does not express the antiinflammatory cytokine interleukin 10 (IL-10) and is, like frail humans, more susceptible to inflammatory pathway activation. We hypothesized that with increasing age, IL-10(tm/t...

OBJECTIVE Thrombomodulin (TM), a glycoprotein constitutively expressed in the endothelium, is well known for its anticoagulant and anti-inflammatory properties. Paradoxically, we recently found that monocytic membrane-bound TM (ie, endogenous TM expression in monocytes) triggers lipopolysaccharide- and gram-negative bacteria-induced inflammatory responses. However, the significance of membrane-...

OBJECTIVE To compare TVT(TM) , Pelvicol(TM) and autologous fascial slings (AFSs). DESIGN A multicentre randomised control trial. SETTING Four units in the UK. POPULATION Women requiring primary surgery for stress urinary incontinence (SUI). METHODS A total of 201 women with urodynamically proven stress incontinence were randomised into three groups and assessed at baseline, 6 weeks, 6 m...

The causal link between disparate tropomyosin (Tm) functions and the structural instability in Tm is unknown. To test the hypothesis that the structural instability in the central region of Tm modulates the function of the overlapping ends of contiguous Tm dimers, we used transgenic mice (Tm(DM)) that expressed a mutant α-Tm in the heart; S229E and H276N substitutions induce structural instabil...

Most cell types express several tropomyosin isoforms, the individual functions of which are poorly understood. In rat fibroblasts there are at least six isoforms; TM-1, TM-2, TM-3, TM-4, TM-5a, and TM-5b. TM-1 is the product of the beta gene. TM-4 is produced from the TM-4 gene, and TMs 2, 3, 5a, and 5b are the products of the alpha gene. To begin to study the localization and function of the i...
