 Biometric identification is an emerging technology that can solve security problems in our networked society. A few years ago, a new branch of biometric technology, palmprint authentication, was proposed [1] whereby lines and points are extracted from palms for personal identification. In this paper, we consider the palmprint as a piece of texture and(More)
The pathological lesions induced by multiwalled carbon nanotubes (MWCNTs) in bronchi and alveoli of mice were studied by intratracheal instillation and inhalation. In instillation groups, the dose was 0.05 mg MWCNTs/mouse. Similar size clumps of MWCNTs were distributed in bronchi and alveoli. The clumps led to inflammation to the lining wall of bronchi and(More)
The dysregulation of the activity of the hypothalamic-pituitary-adrenocortical (HPA) axis system is one of the major neuroendocrine abnormalities in major depression (MD). Many pieces of evidence supported that corticotropin-releasing hormone (CRH) play a role in the pathophysiology of major depression. In this article, whether genetic variations in the(More)
Although many scientists have been attracted by polyhydroxylated fullerenols for their radical-scavenging and antioxidant ability in vivo and in vitro and their potential use as a drug or for drug delivery, there is little information on their pulmonary toxicological properties. The aim of this study was to investigate the effect of polyhydroxylated(More)
This work reported the systematic influence of titanium dioxide nanoparticles (TiO2 NPs) with a diameter of 3 nm on mice. Mice were repeated intratracheally instilled with TiO2 NPs, once per-week for 4 consecutive weeks, at total dose of 13.2 mg/kg. At 28 days post-instillation, the biochemical parameters in broncboalveolar lavage fluid (BALF) and brain(More)
The scorpion venom peptides with no disulfide bridge are rarely identified and poorly characterized so far. Here, we report the identification and characterization of four novel disulfide-bridge-free venom peptides (BmKa1, BmKa2, BmKb1 and BmKn2) from Buthus martensii Kasch. BmKa1 and BmKa2 are very acidic and hydrophilic, showing no any similarity to other(More)
The interaction of multi-walled carbon nanotubes (MWNTs) with living unicellular protozoan Stylonychia mytilus was studied. The results indicated that MWNTs were ingested largely by Stylonychia mytilus. Distribution of MWNTs in the cells, redistribution during dividing process of the cells, and excretion from the cells were observed successfully with(More)
A yellow-pigmented, Gram-reaction-negative, non-motile, aerobic bacterium, designated DR4-30(T), was isolated from tundra soil near Ny-Ålesund, Svalbard Archipelago, Norway (78° 58' N 12° 03' E). Growth occurred at 4-28 °C (optimum 20-25 °C) and at pH 7-8 (optimum pH 7). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain DR4-30(T)(More)
