Dehydrins (DHNs) are a family of plant proteins typically induced in response to stress conditions that cause cellular dehydration, such as low temperatures, high salinity, and drought. Loquat (Eriobotrya japonica) is a perennial fruit crop that blossoms during winter. Loquat fruitlets are frequently injured by freezing. To evaluate the role of the EjDHNs(More)
Face recognition has received significant attention in the last decades for many potential applications. Recently, the scale invariant feature transform (SIFT) becomes an interesting technique for the task of object recognition. This paper investigated the application of the SIFT approach to the face recognition and proposed a new method based on SIFT and(More)
Interstitial cells of Cajal (ICC) have important functions in regulation of motor activity in the gastrointestinal tract. In murine small intestine, ICC are gathered in the regions of the myenteric plexus (ICC-MY) and the deep muscular plexus (ICC-DMP). These two classes of ICC have different physiological functions. ICC-MY are pacemaker cells and generate(More)
The identification of stem-cell-like cancer cells through conventional methods that depend on stem cell markers is often unreliable. We developed a mechanical method for selecting tumorigenic cells by culturing single cancer cells in fibrin matrices of ~100 Pa in stiffness. When cultured within these gels, primary human cancer cells or single cancer cells(More)
Tumour-repopulating cells (TRCs) are a self-renewing, tumorigenic subpopulation of cancer cells critical in cancer progression. However, the underlying mechanisms of how TRCs maintain their self-renewing capability remain elusive. Here we show that relatively undifferentiated melanoma TRCs exhibit plasticity in Cdc42-mediated mechanical stiffening, histone(More)
Rheumatoid arthritis (RA) is the most common autoimmune disorder. Loss of Th1/Th2 and Th17/Treg balance has been reported in several inflammatory autoimmune diseases. This study was to investigate Th1, Th2, Th17, and Treg differentiation and related cytokines in RA patients. The frequencies of Th1, Th2, Th17, and Treg cells in peripheral blood of RA(More)
Mammalian inner cell mass cells undergo lineage-specific differentiation into germ layers of endoderm, mesoderm and ectoderm during gastrulation. It has been a long-standing challenge in developmental biology to replicate these organized germ layer patterns in culture. Here we present a method of generating organized germ layers from a single mouse(More)
Security of mobile ad hoc network (MANET) is very important when we deploy MANET in reality. A variety of attacks exist in MANET. Among them is black hole attack which uses higher sequence number of RREQ packet to provide false route information. To defend against black hole attack, this paper proposed a new method, SRSN (secure routing based on sequence(More)
Cancer metastasis is the most deadly stage in cancer progression. Despite significant efforts over the past decades, it remains elusive why only a very small fraction of cancer cells is able to generate micrometastasis and metastatic colonization. Recently we have shown that tumor-repopulating cells (TRCs), a highly tumorigenic subpopulation of mouse(More)
Inspired by the keyword-based text filter, this paper proposes an image filter which detects the spam image by matching with user-specified image content. In this way, detecting image spam e-mail is converted into image matching process. Stable local feature detection and representation is a fundamental component of image matching algorithms. SIFT has been(More)
