The physiological effects of 4 herbicides (butachlor, quinclorac, bensulfuron-methyl and atrazine) on 3 submerged macrophytes (Ceratophyllum demersum, Vallisneria natans and Elodea nuttallii) were tested in laboratory. The variables of the relative growth rate and the photosynthetic pigment content showed that all of the tested herbicides affected the(More)
We investigate how configurations of urban railroads and highways influenced urban form in Chinese cities since 1990. Each radial highway displaces at least 5 percent of central city population to surrounding regions and ring roads displace an additional 20 percent. Each radial railroad displaces 26 percent of central city industrial GDP with ring roads(More)
Recent years, people pay more and more attention to multi-modal biometric recognition because of its higher security. In this paper, face and palmprint are fused in feature level and a novel user-specific weighting rule is used to adapt different people's need and improve recognition accuracy. According to respective characteristic of face and palmprint,(More)
We explored the clinical and molecular characterization of a Chinese family with non-syndromic hearing impairment. Clinical evaluations revealed a possible maternal inheritance pattern, and showed an extremely similar phenotype of hearing loss including the age of onset, severity, and audiometric configuration. Sequence analysis of the mitochondrial 12S(More)
OBJECTIVE To investigate and evaluate the clinical efficacy and safety of Acticoat with nanocrystalline silver for external use on the management of the residual wounds post-burn. METHODS One hundred and sixty-six wounds of 98 burn patients were enrolled and divided into Acticoat group and silver sulfadiazine group in the multi-center randomized clinical(More)
Nerve growth factor (NGF) is involved in nerve sprouting, hyper-innervation, angiogenesis, anti-apoptosis, and preservation of cardiac function after myocardial infarction (MI). Positively modulating NGF expression may represent a novel pharmacological strategy to improve post-infarction prognosis. In this study, lentivirus encoding NGF short interfering(More)
Arabidopsis heat shock factor HsfA1a is present in a latent, monomeric state under normal conditions; its activation involves heat stress-induced trimerization, binding to heat shock element in target promoters, and the acquisition of transcriptional competence. HsfA1a is an important regulator for heat stress-induced gene expression and thermotolerance.(More)
Tumor-initiating properties of complete carcinogens such as 7,12-dimethylbenz(a)anthracene (DMBA) are well known but not the mechanism of DMBA-mediated tumor promotion. Our hypothesis is that interleukin (IL)-1alpha, an early proinflammatory cytokine that initiates a cascade of other cytokines and growth factors, is up-regulated by DMBA and contributes to(More)
Peroxisome proliferator-activated receptor gamma (PPARγ) belongs to the nuclear receptor superfamily and it has received much attention because of its anti-inflammatory activity. However, the underlying molecular mechanism is not completely understood. In the present study, we demonstrated that the level of PPARγ is inversely correlated with that of high(More)
This paper presents a novel whole body motion estimation method by fitting a deformable articulated model of the human body into the 3D reconstructed volume obtained from multiple video streams. The advantage of the proposed method is two fold: (1) combination of a robust estimator and ICP algorithm with Kd-tree search in pose and normal space make it(More)
