Regulation of protein translation through Akt and the downstream mammalian target of rapamycin (mTOR) pathway is an important component of the cellular response to hypertrophic stimuli. It has been proposed that 5'-AMP-activated protein kinase (AMPK) activation during muscle contraction may limit the hypertrophic response to resistance-type exercise by inhibiting translational signaling. Howeve...

A unique combination of external and internal fixation techniques, for a fibular lengthening procedure using the Ilizarov method is described. The technique is minimally invasive, allows precise deformity correction, enables early weight bearing, and minimizes the time that the patient wears the external fixator. Introduction Bone lengthening procedures have, over time, been approached in a var...

In the present study, we examined the role of the neurokinin-1 receptor (NK1R) in the modulation of respiratory rhythm in a functionally identified bradypnoeic region of the ventral respiratory group (VRG) in the in situ arterially perfused juvenile rat preparation. In electrophysiologically and functionally identified bradypnoeic sites corresponding to the Bötzinger complex (BötC), microinject...

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...
