Replanted Calligonum caput-medusae saplings in the Tarim River watershed face short-term and frequent herbivory by goats, which can result in either growth inhibition or stimulation. The effects of herbivory on shrub saplings are unclear. We simulated herbivory with clipping to test two hypotheses. We hypothesized that (1) moderate herbivory may positively(More)
Neurons depend for survival on local neurotrophic factors which act in an autocrine/paracrine manner. However, the effect of paracrine signaling of brain microvascular endothelial cells (BMECs) under pathological conditions on neuron survival is not fully understood. In this study we cultured rat BMECs and cortical neurons. BMECs were cultured in(More)
As emerging tick born rickettsial diseases caused by A. phagocytophilum and E. chaffeensis, anaplasmosis and ehrlichiosis have become a serious threat to human and animal health throughout the world. In particular, in China, an unusual transmission of nosocomial cases of human granulocytic anaplasmosis occurred in Anhui Province in 2006 and more recent(More)
The pathological hallmarks of Alzheimer’s disease (AD) include formation of extracellular amyloid-β peptide (Aβ) and inflammatory responses. Numerous studies have reported that cerebral microvascular Aβ deposition promotes neuroinflammation in AD. Matrix metalloproteinases (MMPs) are involved in the cleavage of extracellular matrix proteins and regulation(More)
Many randomized clinical controlled trials have confirmed the efficacy and safety of calcium dobesilate in treating diabetic retinopathy (DR). This systematic review critically evaluated the evidence that links calcium dobesilate to DR. In this fixed-effects meta-analysis, a total of 221 pertinent English-language articles published between January 1975 and(More)
Based on the first National Study of Coal Workers' Pneumoconiosis (CWP) and the U.S. Geological Survey database of coal quality, we show that the prevalence of CWP in seven coal mine regions correlates with levels of bioavailable iron (BAI) in the coals from that particular region (correlation coefficient r = 0.94, p < 0.0015). CWP prevalence is also(More)
To investigate the risk factors of scrub typhus infection in Beijing, China, a case-control study was carried out. Cases (n = 56) were defined as persons who were diagnosed by PCR and serological method within three years. Three neighborhood control subjects were selected by matching for age and occupation. Living at the edge of the village, living in the(More)
Based on the observed data from 51 meteorological stations during the period from 1958 to 2012 in Xinjiang, China, we investigated the complexity of temperature dynamics from the temporal and spatial perspectives by using a comprehensive approach including the correlation dimension (CD), classical statistics, and geostatistics. The main conclusions are as(More)
In this paper, we propose an effective human and nonhuman pyroelectric infrared (PIR) signal recognition method to reduce PIR detector false alarms. First, using the mathematical model of the PIR detector, we analyze the physical characteristics of the human and nonhuman PIR signals; second, based on the analysis results, we propose an empirical mode(More)
BACKGROUND AND METHODS Commercial pure titanium with nanotopography was prepared via a high-energy shot-peening (HESP) technique. The surface characteristics were evaluated, and the preliminary cell responses to the nanotopographical surface were investigated. RESULTS The nanotopographical surface layer on titanium was successfully processed by HESP. The(More)
