There are two main problems with muscle tendon lengthening: thinness created by the technical procedure weakens the tendon, and in short tendons, lengthening may not provide enough length for the amount of joint motion required. In proximal rectus femoris lengthening, the distal ends of the reflected and straight heads are sutured together. Using this technique, the tendon will not be thinned, ...

Recombination-mediated pathways for telomere lengthening may be utilized in the absence of telomerase activity. The RecQ-like helicases, BLM and Sgs1, are implicated in recombination-mediated telomere lengthening in human cells and budding yeast, respectively. Here, we show that BLM expression rescues disrupted telomere lengthening in telomerase-negative sgs1 yeast. BLM helicase activity is req...

nowadays, due to recent developments and researches in dental science, it is possible to preserve and restore previously extracted cases such as teeth with extensive caries, fractured or less appropriate cases for crown coverage as well as teeth with external perforation caused by restorative pins. in order to restore the teeth with preservation of periodontium, we should know thoroughly physio...

Contraction-induced injury occurs when muscles are stretched while activated (lengthening contractions). The injury is initiated by mechanical damage followed by an inflammatory response. Old animals are particularly susceptible to contraction-induced injury, yet exposure to stretches without activation (passive stretches) before lengthening contractions lessens the injury. We hypothesized that...

This paper presents results from the analysis of segmental duration in French in three different speaking styles, (a) 'reading'; (b) 'news broadcast' ; (c) 'spontaneous interview'. A ten minute corpus was hand segmented and labelled using six accent categories (i) unstressed (ii) word-initial (iii) emphatic word-initial (iv) word-final (v) intonation unit final before non-terminal boundary (vi)...

There is a definite need to determine the exact size and shape of a stump or extremity in order to ascertain quickly any changes in contour and size, and at the same time to have tracings of the periodic reevaluations. A number of methods are presently used, such as the water displacement method, measuring the circumference of the stump or extremity at a number of points, and photography. None ...

Long nerve stumps will maintain end-organs for a longer period of time than short nerve stumps. However, longer maintenance might result not from a longer nerve stump per se but from uncontrolled factors such as less interference with the target's blood supply when transecting a nerve far from its target. To control for the site of nerve transection and to evaluate the trophic capacity of lengt...
