OBJECTIVE To investigate the functional connectivity (FC) pattern within an intrinsic functional organization, including both task-positive (TPN) and task-negative (TNN) networks, in major depressive disorder (MDD), and to examine relationships between the involved FCs and clinical variables. METHODS Resting-state FC analyses were used to identify the(More)
Müller glia have been demonstrated to display stem-cell properties after retinal damage. Here, we report this potential can be regulated by Sonic hedgehog (Shh) signaling. Shh can stimulate proliferation of Müller glia through its receptor and target gene expressed on them, furthermore, Shh-treated Müller glia are induced to dedifferentiate by expressing(More)
BACKGROUND Organic substrates and calcium are important factors controlling organic matter turnover in Karst soils. To understand their effects on soil organic carbon (SOC) mineralization, an incubation experiment was conducted involving a control treatment (CK), the addition of a (14)C-labeled rice straw (T1), CaCO(3) (T2), and both (14)C-labeled rice(More)
Airborne bacteria are important biological components of bioaerosol and play an important role in ecosystem. Bacteria at a high concentration in the atmosphere can result in biological air pollution and all kinds of diseases. In this study, a systematical survey on the culturable airborne bacteria was carried out for 1 year at three sites in Beijing urban(More)
To determine whether photoreceptor degeneration can stimulate Müller glia to transdifferentiate into neurons in adult mammalian retina, N-methyl-N-nitrosourea (MNU) was injected to induce complete loss of photoreceptors. Following MNU administration, Müller glia underwent reactive gliosis characterized by up-regulation of glial fibrillar acidic protein and(More)
Airborne fungi are being proposed as a cause of adverse health effects. They may adversely affect human health through allergy, infection, and toxicity. Moreover, they have a great influence on urban air quality in Beijing. In this study, a systematical survey on the culturable airborne fungi was carried out for 1 year in Beijing urban area. Fungal samples(More)
The urban heat island describes the phenomenon that air/surface temperatures are higher in urban areas compared to their surrounding rural areas. Numerous studies have shown that increased percent cover of greenspace (PLAND) can significantly decrease land surface temperatures (LST). Fewer studies, however, have investigated the effects of configuration of(More)
Plant species composition is a critical issue in ecological research. Studies on the characteristics of plant species composition in the built-up areas, however, are hampered by a lack of basic field-based investigation. In this article, the plant species composition in the built-up areas of Beijing, China, is investigated using abundant field observations.(More)
Despite broad interest in using payment for ecosystem services to promote changes in the use of natural capital, there are few expost assessments of impacts of payment for ecosystem services programs on ecosystem service provision, program cost, and changes in livelihoods resulting from program participation. In this paper, we evaluate the Paddy Land-to-Dry(More)
The purpose was to examine the brain activation patterns with acupuncture using real acupoint (Liv3) versus sham acupoint in healthy, sedated children using functional magnetic resonance imaging (fMRI). Functional magnetic resonance imaging scans of the brain for 10 healthy, sedated children were taken during stimulation of real acupoint (Liv3 [Taichong])(More)
