Effects of electroacupuncture combined with computer-based cognitive rehabilitation on mild cognitive impairment: study protocol for a pilot randomized controlled trial.

Background: Mild cognitive impairment (MCI) is defined as an intermediate stage between normal aging and Alzheimer's disease (AD), and early and easily available interventions to delay the progress of MCI to AD are necessary. Feasible complementary and alternative therapies such as electroacupuncture (EA), exercise, and cognitive training have shown some beneficial effects on MCI and AD. Here we report the protocol for a randomized controlled trial of the efficacy and safety of EA combined with computer-based cognitive rehabilitation (EA-CCR) for the treatment of MCI.

Protective Effects of Flesh and Peel Extracts against Ethanol-Induced Gastric Ulcer in Mice.

Gastric ulcer is a major digestive disorder and provoked by multifactorial etiologies, including excessive alcohol consumption. In this study, we examined the gastroprotective effect of aqueous and ethanolic extracts of Decne (DBD; commonly called Chinese yam) flesh or peel against acidified ethanol-induced acute gastric damage in mice. Our findings demonstrated that oral supplementation of aqueous or ethanolic extracts of DBD flesh or peel before ulcer induction was significantly effective in macroscopically and histologically alleviating ethanol-induced pathological lesions in gastric mucosa, decreasing the plasma levels of inflammatory mediators, such as nitric oxide and interleukin-6, attenuating the gastric expression of cyclooxygenase-2, and increasing the gastric content of prostaglandin E₂.

Protective Effect of Glyceollins in a Mouse Model of Dextran Sulfate Sodium-Induced Colitis.

Glyceollins, which are derived from daidzein in soybean in response to various stimuli or stresses, have been reported to activate antioxidant/detoxifying enzymes in a nuclear factor (erythroid-derived 2)-like 2 (Nrf2)-dependent manner, in addition to exerting anti-inflammatory effects in murine macrophages. As the Nrf2 signaling pathway is known to antagonize nuclear factor (NF)-κB signaling, glyceollins likely have the potential to prevent or treat inflammatory bowel disease. Thus, this study was conducted to examine whether glyceollins could inhibit dextran sulfate sodium (DSS)-induced colitis in a mouse model.

Enhanced cardiomyogenic induction of mouse pluripotent cells by cyclic mechanical stretch.

The cardiac milieu is mechanically active with spontaneous contraction beginning from early development and persistent through maturation and homeostasis, suggesting that mechanical loading may provide a biomimetic myocardial developmental signal. In this study, we tested the role of cyclic mechanical stretch loading in the cardiomyogenesis of pluripotent murine embryonic (P19) stem cells. A Flexcell tension system was utilized to apply equiaxial stretch (12% strain, 1.

Flowtaxis of osteoblast migration under fluid shear and the effect of RhoA kinase silencing.

Despite the important role of mechanical signals in bone remodeling, relatively little is known about how fluid shear affects osteoblastic cell migration behavior. Here we demonstrated that MC3T3-E1 osteoblast migration could be activated by physiologically-relevant levels of fluid shear in a shear stress-dependent manner. Interestingly, shear-sensitive osteoblast migration behavior was prominent only during the initial period after the onset of the steady flow (for about 30 min), exhibiting shear stress-dependent migration speed, displacement, arrest coefficient, and motility coefficient.

Focal adhesion kinase regulation in stem cell alignment and spreading on nanofibers.

While electrospun nanofibers have demonstrated the potential for novel tissue engineering scaffolds, very little is known about the molecular mechanism of how cells sense and adapt to nanofibers. Here, we revealed the role of focal adhesion kinase (FAK), one of the key molecular sensors in the focal adhesion complex, in regulating mesenchymal stem cell (MSC) shaping on nanofibers. We produced uniaxially aligned and randomly distributed nanofibers from poly(l-lactic acid) to have the same diameters (about 130 nm) and evaluated MSC behavior on these nanofibers comparing with that on flat PLLA control.
