A novel Gram stain-negative, catalase- and oxidase-positive, strictly aerobic bacterium, designated strain H50T, was isolated from an amphioxus breeding zone in the coastal region of the Yellow Sea, China. Cells were observed to be ovoid or short rods, lacked flagella and were found to contain bacteriochlorophyll a. Poly-beta-hydroxybutyrate was found to be(More)
Alzheimer's disease (AD) is a neurodegenerative disease with major clinical hallmarks of memory loss, dementia, and cognitive impairment. Neuroinflammation is involved in the onset of several neurodegenerative disorders. Astrocyte is the most abundant type of glial cells in the central nervous system (CNS) and appears to be involved in the induction of(More)
Ischemia occurs in the brain as the result of stroke and other related injuries and few therapies are effective. If more is understood then potential treatments could be investigated. It was previously reported that 14-3-3gamma could be up-regulated by ischemia in astrocyte to protect cells from ischemia-induced apoptosis. In this study, we attempted to(More)
Expression cloning was used to initially isolate the reversion-inducing cysteine-rich protein with Kazal motifs (RECK) gene as a suppressor of transformation. The gene was found to encode a membrane-anchored regulator of MMPs. Experimental studies showed that RECK can suppress tumor invasion, metastasis, and angiogenesis. However, the clinical impact of(More)
Single-molecule fluorescence resonance energy transfer (smFRET) microscopy has become an increasingly popular tool to study the structural dynamics of RNA molecules. It reveals, in real time, the structural dynamics of these molecules that would be otherwise hidden in ensemble-averaged measurements. Here we present a detailed protocol for performing smFRET(More)
This study analyzes the in vitro effects of cations and pH on antimicrobial activity of thanatin and s-thanatin against Escherichia coli ATCC25922 and B. subtilis ATCC21332. Thanatin and s-thanatin were synthesized by the solid-phase method using a model 432A synthesizer. The bacterial strains tested included two antibiotic-susceptible strains of(More)
Uniform-sized molecularly imprinted polymer (MIP) beads for metsulfuron-methyl (MSM) were firstly prepared by one-step swelling and polymerization method using 4-vinylpyridine (4-VPY) and ethylene glycol dimethacrylate (EDMA) as functional monomer and cross-linker, respectively. The preparation was optimized by varying the ratio of MSM to 4-VPY. The(More)
A novel Gram-stain-negative, rod-shaped, non-flagellated, strictly aerobic strain with gliding motility, designated SW024(T), was isolated from surface seawater of the South Pacific Gyre (26° 29' S 137° 56' W) during the Integrated Ocean Drilling Program Expedition 329. Phylogenetic analyses based on 16S rRNA gene sequences showed that the novel strain was(More)
A Gram-negative, strictly aerobic, motile, short rod-shaped bacterium with peritrichous flagella, designated JYr12T, was isolated from sediment of an amphioxus breeding zone in the coastal region of Qingdao, China. Strain JYr12T was found to grow optimally at 28 °C, at pH 7.0 and in the presence of 2–3 % (w/v) NaCl. The organism was determined to contain(More)
s-thanatin, an analogue of thanatin, was synthesised by substituting the fifteenth amino acid threonine with serine and showed broad antimicrobial activity against Gram-negative and Gram-positive bacteria. To evaluate its antimicrobial activity against a multidrug-resistant (MDR) clinical isolate as well as its anti-endotoxin activity, its(More)
