BACKGROUND Mechanical stimulation of bone increases bone mass and fracture healing, at least in part, through increases in proliferation of osteoblasts and osteoprogenitor cells. Researchers have previously performed in vitro studies of ultrasound-induced osteoblast proliferation but mostly used fixed ultrasound settings and have reported widely varying and inconclusive results. Here we critica...

In this paper, we have considered the problem of rotating, magnetohydrodynamic heat and mass transfer by free convective flow past an exponentially accelerated isothermal vertical plate in the presence of variable mass diffusion. While the temperature of the plate is constant, the concentration at the plate is considered to be a linear function with respect to time t. The plate is assumed to be...

background  spermatogonial stem cells (sscs) are the foundation of spermatogenesis. sound wave especially low intensity ultrasound (lius) can be effective on increasing the number of cells. in this study we investigated the effect of lius stimulation on mouse sscs proliferation and colonization. methods: isolated sscs from neonate mice cultured in dmem culture medium with 10% fetal bovine serum...

Overactive epidermal growth factor receptor (EGFR) signaling often underlies the rapid expansion of cancerous tissue. EGFR signaling is mediated by transcription factor signal transducer and activator of transcription 3, or STAT3. This study sought to investigate the effects of altered EGFR/STAT3 signal transduction on lung cancer cells in vitro. Lung cancer cells from the cell line A549 were d...

Background and Aim: Recently, several studies have indicated that the central nervous system has the capacity for endogenous repair. But, the proliferation capacity of endogenous neural stem cells (NSCs) isn’t sufficient for the treatment of neurodegenerative diseases. So, it sounds that stimulation of endogenous NSC proliferation is essential for neuroregeneration. The aim of this study ...
