We have studied the effect of shortening of the femoral neck and varus collapse on the functional capacity and quality of life of patients who had undergone fixation of an isolated intracapsular fracture of the hip with cancellous screws. After screening 660 patients at four university medical centres, 70 patients with a mean age of 71 years (20 to 90) met the inclusion criteria. Overall, 66% (...

Force depression observed following active shortening is not well understood. Previous research suggested that force depression might be associated with a stress-induced inhibition of cross-bridges in the newly formed overlap zone following shortening. Our aim was to investigate this theory in skinned fibres and determine whether there was an inhibition of the attachment of cross-bridges or a d...

OBJECTIVES This study examined left ventricular performance in relatively unselected hypertensive patients by use of physiologically appropriate midwall shortening/end-systolic stress relations. BACKGROUND Supranormal left ventricular function has been reported in hypertensive patients, possibly due to an artifact of mismatching endocardial rather than midwall fractional shortening to mean le...

The bulk of the crustal shortening across Himalayas is accommodated Main Frontal Thrust (MFT), forming topographic ridges Siwalik Hills. Here, we quantify metrics to document geomorphic response progressive shortening. We use integral method channel profile analysis assess development thrust anticline in eastern and western Churia, Dundwa, Mohand Ranges. River steepness (ksn), distribution knic...

Total oxygen consumption following contraction at controlled shortening velocities was determined for ten twitches of frog sartorius muscle. Under the conditions of this investigation maximum oxygen consumption occurred at approximately 30 mm/sec. shortening velocity and decreased for larger and smaller velocities. Mechanical efficiency was calculated and found to show a maximum at approximatel...

The aim of this study was to compare two surgery methods including radial shortening and radial shortening combined with vascularized bone graft for treatment of stage II or IIIa of Kienböck's disease. It is a randomized, controlled clinical trial, which was carried out in 2011-2013. Twenty-four patients were assigned equally to radial shortening group (A) or radial shortening combined with vas...

Objective Analyzing if the sonographic evaluation of the cervix (cervical shortening) is a prognostic marker for vaginal delivery. Methods Women who underwent labor induction by using dinoprostone were enrolled. Before the induction and three hours after it, the cervical length was measured by ultrasonography to obtain the cervical shortening. The cervical shortening was introduced in logistic ...

During the contraction phase of isotonic twitch there must be the change of muscle force. When initial acceleration was augmented by using heavy load or inertia lever 1,2,3), the muscle tension developed far bigger than the load and the condition of twitch was not 'isotonic' in real meaning. As far as a single twitch was concerned, the change of force should not be neglected. In the previous st...

Shortening of chromosome ends, known as telomeres, is one of the supposed mechanisms of cellular aging and death. We provide a probabilistic analysis of the process of loss of telomere ends. The first work concerned with that issue is the paper by Levy et al. [J. Molec. Biol. 225 (1992) 951-960]. Their deterministic model reproduced the observed frequencies of viable cells in the in vitro exper...
