objective: cell vital function has correlation with mechanical loadings that cell experiences. here, effects of in-vitro combined cyclic-static stretch on proliferation of human mesenchymal stem cell (hmsc) were evaluated. materials and methods: hmscs were cultured on gelatin coated elastic membranes, and exposed to stretch loading. four different regimes of cyclic, static, combined cyclic-sta...

this study was a clinical trial performed using consecutive method of samplind for 3.5 years in the physiotherapy clinic of Rafsanjan university of medocal sciences.the purpose of this research was to evaluate the effect of the ultrasound along with muscle stretch with ultrasound and muscle stretch along in the treatment of the myofascial trigger points(MTPs).one haundred and twenty patients wh...

chapatti is high consuming bread in the southeast countries of asia that in fresh form has a tender texture but within a few days of storage, becomes inflexible. in this research, the effects of guar and cmc gums at two levels of 0.25 and 0.5% on quality of chapatti bread were investigated. based on results, gum addition in different levels increased moisture and ash contends and improved rheol...

background: mesenchymal stem cells (mscs) can be expanded and differentiated into many mature cell types including smooth muscle cells (smcs). in addition to growth factor, cyclic stretch contributes to differentiation of stem cells. mechanical stimuli are critical to morphological changes, development, regeneration, differentiation and pathology of mesenchymal tissues. the aim of this study is...

It has been suggested that species with high breathing frequencies have pulmonary stretch receptors which adapt more rapidly than species with low breathing frequencies. This has proved not to be so. Our hypothesis is that this theory is in fact correct if modified so that overall rate of adaptation of afferent vagal activity, i.e. the sum of stretch and rapidly adapting receptors, is considere...

Structures consisting of cables and membranes have been of interest to engineers due to their higher ratio of strength to weight and lower cost compared to other structures. One of the challenges in such structures is presence of holes in membranes, which leads to non-uniform stress and strain distributions, even under uniform far-field deformations. One of the approaches suggested for controll...

conclusions the two treatment methods had similar effects and there were no significant difference between them, while significant improvement was seen in the experimental groups compared with the control group. background shortness of skeletal muscles may cause musculoskeletal disorders of body; improvement of these muscles may improve posture and body function. objectives the aim of this stud...

It has been reported that triangular-shaped positive pressure pulses applied to the airway (high-frequency inflation, HFI) stimulates pulmonary stretch receptors and prolongs expiratory duration. In the present experiment, changes in the integrated curve of expiratory activity induced by HFI were investigated. Duration until the onset of the expiratory activity (E1 stage) was unchanged. In the ...

amodified technique is designed to prepare aligned nanofibers to challenge the existing limitations in collecting methods of nanofibers such as, thickness of collected layer, alignment and productivity of nanofibers. collecting and simultaneously heating of the aligned nanofibers were carried out by using a rotating drum fixed on top of syringe needles and applying hot air flow. this electrospi...
