In addition to systemic and local factors, mechanical strain plays a crucial role in bone remodeling during growth, development, and fracture healing, and especially in orthodontic tooth movement. Although many papers have been published on the effects of mechanical stress on osteoblasts or osteoblastic cells, little is known about the effects of different(More)
Limitations of conventional regeneration modalities underscore the necessity of recapitulating development for periodontal tissue engineering. In this study, we proposed a novel three-dimensional pellet cultivation system for periodontal ligament stem cells (PDLSCs) to recreate the biological microenvironment similar to those of a regenerative milieu.(More)
To explore the interactions among immunity related genes and the risk of breast cancer (BC), 376 invasive ductal carcinoma (IDC) of the breast cases and 366 healthy controls were selected into our study. Twenty single nucleotide polymorphisms (SNPs) of five immunological genes in the CD28/B7 pathway were genotyped. Overall, five SNPs filtered by the Relief(More)
The response of cells in the distraction gap during mandibular distraction osteogenesis was recorded by transmission electronic microscopy. We distracted the mandible on both sides in eight adult goats. Two animals were killed at 8, 16, 32, and 48 days, respectively, after activation of the device. The specimens were harvested and processed for histological(More)
Although Bell's palsy is the most common acute facial paralysis, the cause of it is still unknown. This made the treatment for it remain very limited. Many methods are simply symptomatic treatment. Up to now we have known that Bell's palsy is related to viral infection and the pathomechanism of Bell's palsy involves inflammatory oedema and entrapment(More)
In response of the fact that traditional intrusion detection systems are not able to fulfill the requirements for specific network security, such as fast processing speed, stronger defense capability, and higher real-time performance, a model of network security defense is built on the integration of data stream mining and intrusion detection; and, a data(More)
Much correlative evidence indicates that the oxidative modification of protein by reactive oxygen species (ROS) is involved in normal aging as well as the pathogenesis of neurodegenerative diseases such as Alzheimer's disease. In this study, we explored the antioxidative and neuroprotective effects of a naphthoquinone, 2-methoxy-6-acetyl-7-methyljuglone(More)
The Na+-K+-ATPase and its regulation is important for maintaining membrane potential and transmembrane Na(+) gradient in all skeletal muscle cells and thus is essential for cell survival and function. In our previous study, cyclic stretch activated the Na pump in cultured skeletal muscle cells. Presently, we investigated whether this stimulation was the(More)
Skeletal muscle cells are exposed to mechanical stretch during embryogenesis. Increased stretch may contribute to cell death, and the molecular regulation by stretch remains incompletely understood. The aim of this study was to investigate the effects of cyclic stretch on cell death and apoptosis in myoblast using a Flexercell Strain Unit. Apoptosis was(More)
The Na(+)-K(+)-ATPase, which plays a major role in modulation of skeletal muscle excitability and contractility, is one of the marker enzymes that senses the mechanical strain and adapts to the stimuli. Although many papers had been published on the effects of mechanical stress on Na(+)-K(+)-ATPase in aortic smooth muscle cells, little was known about the(More)
