A novel facultative psychrotroph (strain CBS-1), which accumulates poly-β-hydroxybutyrate (PHB), was isolated from soil samples taken from Changbai Mountain, China. Phylogenetic analysis based on 16S rRNA sequence data and Biolog analysis identified strain CBS-1 as Pseudomonas mandelii. Transmission electron micrographs revealed abundant electron-transparent intracellular granules. (1)H-nuclear...

BACKGROUND Sulfur metabolism is required for initiation of cell division, but whether or not it can actively promote cell division remains unknown. METHODOLOGY/PRINCIPAL FINDINGS Here we show that yeast cells with more mtDNA have an expanded reductive phase of their metabolic cycle and an increased sulfur metabolic flux. We also show that in wild type cells manipulations of sulfur metabolic f...

The significantly higher event-free survival rates of Down syndrome (DS) children with acute myeloid leukemia compared with non-DS children is linked to increased sensitivity of DS myeloblasts to 1-b-D-arabinofuranosylcytosine (ara-C) and the enhanced metabolism of ara-C to ara-C triphosphate (J. W. Taub et al., Blood, 87: 3395–3403, 1996). The cystathionine-b-synthase (CBS) gene (localized to ...

Several theories propose that the cortex implements an internal model to explain, predict, and learn about sensory data, but the nature of this model is unclear. One condition that could be highly informative here is Charles Bonnet syndrome (CBS), where loss of vision leads to complex, vivid visual hallucinations of objects, people, and whole scenes. CBS could be taken as indication that there ...

Component Based System (CBS) development is integration centric with a focus on selecting components that match stakeholder requirements. Recent research suggests that CBS development needs a quantitative analysis model that evaluates candidate components and facilitates informed decisions during CBS development. To date, there has been little work done on building CBS assessment models that ca...

To explore the novel properties of carbon nanoparticles (CNPs) in nanotoxicity assays, the adsorption of phenol red (a pH indicator for culture medium) by multi-walled carbon nanotubes (MWNTs) and three kinds of carbon blacks (CBs) with nanosize, and its effects on cytotoxicity were studied. Results indicated that the phenol red adsorbed and delivered into cells by CBs was responsible for the t...

The Charles Bonnet Syndrome (CBS) is characterized by complex vivid visual hallucinations in people with, primarily, eye diseases and no other neurological pathology. We present a Deep Boltzmann Machine model of CBS, exploring two core hypotheses: First, that the visual cortex learns a generative or predictive model of sensory input, thus explaining its capability to generate internal imagery. ...

The Cajal body (CB) is a conserved, dynamic nuclear structure that is implicated in various cellular processes, such as the maturation of splicing small nuclear ribonucleoproteins and the assembly of transcription complexes. Here, we report the first procedure for the large-scale purification of CBs from HeLa cell nuclei, resulting in an approximately 750-fold enrichment of the CB marker protei...

A hierarchical family of five three-dimensional potential energy surfaces has been developed for the benchmark He-CO system. Four surfaces were obtained at the coupled cluster singles and doubles level of theory with a perturbational estimate of triple excitations, CCSD(T), and range in quality from the doubly augmented double-zeta basis set to the complete basis set (CBS) limit. The fifth corr...

The lager brewing yeasts, Saccharomyces pastorianus (synonym Saccharomyces carlsbergensis), are allopolyploid, containing parts of two divergent genomes. Saccharomyces cerevisiae contributed to the formation of these hybrids, although the identity of the other species is still unclear. The presence of alleles specific to S. cerevisiae and S. pastorianus was tested for by PCR/RFLP in brewing yea...
