OBJECTIVES To examine whether acupuncture could improve cognitive deficits and reduce the loss of neurons in mice models of ageing. METHODS Male 7.5-month-old senescence-accelerated mouse prone 8 (SAMP8) and age-matched senescence-resistant inbred strains 1 (SAMR1) were divided into four groups (n=15 per group): SAMP8 acupuncture group (Pa), SAMP8(More)
The objective of this study is to examine whether neuron loss occurs in SAMP8 and whether neuron loss is correlated with cognitive deficits of these mice. Neuronal loss is considered as one of the most important pathological hallmarks of Alzheimer disease (AD). In addition to the early-onset, irreversible, severe deficits of learning and memory, SAMP8 mice(More)
Classification over data streams is an important task in data mining. The challenges become even larger when uncertain data are considered. An important challenge in the classification of uncertain data streams is concept drift and uncertainty of data. This paper studies the problem using extreme learning machine (ELM). We first propose weighted ensemble(More)
Generally, effect of fragmentation per se on biodiversity has not been separated from the effect of habitat loss. In this paper, using nDNA and cpDNA SSRs, we studied genetic diversity of Castanopsis sclerophylla (Lindl. & Paxton) Schotty populations and decoupled the effects of habitat loss and fragmentation per se. We selected seven nuclear and six cpDNA(More)
Pien Tze Huang (PZH) is a well-known Chinese medicine that has been used as a therapeutic drug in the treatment of a number of diseases, such as hepatocellular carci-noma and colon cancer. However, few studies have analyzed the effects of PZH on ovarian cancer cell proliferation. In the present study,
Comprehensive studies on the genetic diversity and structure of endangered species are urgently needed to promote effective conservation and management activities. The big tree rhododendron, Rhododendron protistum var. giganteum, is a highly endangered species with only two known endemic populations in a small area in the southern part of Yunnan Province in(More)
A new cell line named RIRI-PaDe, developed from the neonate larvae of Papilio demoleus Linnaeus, was established in modified Grace’s medium supplemented with 20% fetal bovine serum. The cell line was incubated at 28°C and consisted of attached round and short spindle-like cells. The population doubling time was 55 h. The chromosome numbers varied widely(More)
Scalable vocabulary tree (SVT) is a data compression structure which gains scalable visual vocabularies from hierarchical k-means clustering of local image features. Due to both high robustness in data retrieval and great potentials to process huge data, it has become one of the state-of-the-art methods building on the bag-of-features. However, such(More)
From a visual point of view, the shape of an image is mainly determined by the edges. Conventional polynomial interpolation of image enlarging methods would produce blurred edges, while edge-directed interpolation based methods would cause distortion in the non-edge areas. A new method for image enlarging is presented. The image is enlarged in two steps. In(More)
