Excessive autophagy aggravates myocardial ischemia/reperfusion (IR) injury. Hydrogen sulfide (H2S) has been shown to possess a strong cardioprotective effect due to its anti-necrosis, anti-apoptosis, anti-oxidant and anti-inflammatory properties. Our previous study showed that H2S could also protect the myocardium against IR injury through its(More)
Root resorption is a common side effect of orthodontic treatment. In the current study, lithium chloride (LiCl), a Wnt signaling activator, was examined to determine its effect on root resorption. In total, 10 Sprague Dawley rats were randomly allocated into the experimental group (EG) and control group (CG). Each group consisted of five subjects. By using(More)
Chitosan stabilized silver nanoparticles (Ch-Ag NPs) were successfully synthesized by a one-step method and were found to possess intrinsic peroxidase-like activity, could catalytically oxidize substrates, such as TMB, and OPD, by H(2)O(2) to produce a typical colour reaction such as from colorless to blue for TMB and from colorless to red for OPD. Our(More)
The objective of this work was to evaluate the structure-function relationship between grape skin extract and human α-amylase. The grape skin extract was characterised as resveratrol-3-O-glucoside by RP-HPLC-ESI-MS, which showed strong inhibition towards α-amylase and the IC50 value was 1.35 mg/ml. The kinetic results demonstrated grape skin extract obeyed(More)
INTRODUCTION Evidence suggests that current levels of tritium emissions from CANDU reactors in Canada are not related to adverse health effects. However, these studies lack tritium-specific dose data and have small numbers of cases. The purpose of our study was to determine whether tritium emitted from a nuclear-generating station during routine operation(More)
Behavioral and brain development is influenced by both maternal and non-maternal aspects of the postnatal environment and the precise nature of their interaction is the topic of an ongoing debate. Here, we consider the joint influence of neonatal environmental novelty and maternal self-stress regulation on the development of acoustic startle reflex (ASR),(More)
To quantitatively assess the histological and ultrastructural changes resulting from aging in the human testis. Age-related histological and ultrastructural changes were evaluated using light microscopy, transmission electron microscopy (TEM) and immunohistochemistry on 41 testicular samples obtained from elderly men and, respectively, assigned to group A(More)
Cerium (Ce), one of the lanthanides (Ln), displays a variety of biochemical and physiological effects. However, the potential effect and mechanism of Ce on bone metabolism are not well understood. In this study, we investigated the putative role of Ce in regulating the migration and osteogenic differentiation of bone marrow stromal cells (BMSCs) and the(More)
INTRODUCTION Orthodontic forces produce a series of changes in dental pulp. However, no one has attempted to investigate the incidence of pulp necrosis after orthodontic therapy in the clinic. In this study, we aimed to investigate pulp vitality and histologic changes after the application of moderate and severe intrusive forces. METHODS Twenty-seven(More)
Invasive plants have caused great economic losses and environmental problems worldwide. Eupatorium adenophorum is one of the most invasive weeds in China. To better understand its invasive mechanisms, in the present paper, the microbial communities of healthy and diseased leaves of E. adenophorum were obtained using both culture-independent and -dependent(More)
