AIMS Mechanogated ion channels are predicted to mediate pressure-induced myogenic vasoconstriction in small resistance arteries. Recent findings have indicated that transient receptor potential (TRP) channels and epithelial sodium channels (ENaC) are involved in mechanotransduction. The purpose of this study was to investigate the role of TRP channels and ENaC in the myogenic response. Our prev...

We show that muscle satellite cells, traditionally considered as committed myogenic precursors, are comprised of Pax7-expressing progenitors that preserve a mesenchymal repertoire extending beyond a mere myogenic potential. Mouse satellite cells from freshly isolated single myofibers, cultured individually in serum-rich growth medium, produced myogenic and non-myogenic clones. Only the myogenic...

At a recent meeting of the Bath and Bristol Branch of the British Medical Association1 I showed some lantern slides illustrating ptosis, and it has been suggested to me that a short resume of the cases might be of interest to the readers of the Bristol Medico-Chirurgical Journal. The ptosis was symptomatic of ophthalmoplegia externa, and the unusual point was that it came on in middle life in t...

THE instrument shown in Fig. 1 (a) and (b) is a spatula in two sizes, one smaller for children and the other larger for adults, curved to conform with the forward convexity of the tarsal plate in the upper eyelid; the upper edge of the spatula is rounded and curved to be accommodated in the superior fornix. That part of the spatula which projects below the upper lid margin, after its insertion ...

Muscle side population (SP) cells are rare myogenic progenitors distinct from satellite cells, the known tissue-specific stem cells of skeletal muscle. Studies in mice demonstrated that muscle SP cells give rise to satellite cells in vivo. Given that muscle SP cells are heterogeneous, it has been difficult to prospectively enrich for myogenic progenitors within the SP fraction, particularly fro...

there are many tests for diagnosis of myasthenia gravis including tensilon test and ice test.to compare the ice test with tensilon test in sub jects with myasthenic and nonmyasthenic ptosis a process research study was designed. this study was performed in patients complaining of acquired ptosis in the neuro-ophthalmology center of farabi hospital. all 156 patients were tested with ice pack and...
