Idiomarina gen. nov., comprising novel indigenous deep-sea bacteria from the Pacific Ocean, including descriptions of two species, Idiomarina abyssalis sp. nov. and Idiomarina zobellii sp. nov.
Two bacterial strains, KMM 227T and 231T, were isolated from seawater samples collected from the north-western Pacific Ocean at a depth of 4000-5000 m and were characterized using polyphasic taxonomy, indicating that the two strains formed a distinct lineage within a clade containing the genera Alteromonas, Colwellia and Pseudoalteromonas in the gamma-Proteobacteria.

Simultaneous hyperaccumulation of nickel, manganese, and calcium in Alyssum leaf trichomes.
The region-specific localization of hyperaccumulated Ca, Mn, and Ni occurred in three soil types, five Alyssum species/ecotypes, and over a wide range of soil Ni concentrations, the highest ever reported for healthy vascular plant tissue. Expand
Nickel localization and response to increasing Ni soil levels in leaves of the Ni hyperaccumulator Alyssum murale
We have previously developed phytoremediation and phytomining technologies employing Alyssum Ni hyperaccumulators to quantitatively extract Ni from soils. Implementation of these technologiesExpand
Caveolae internalization repairs wounded cells and muscle fibers
This work shows that muscle fibers and other cell types repair membrane wounds by a mechanism involving Ca2+-triggered exocytosis of lysosomes, release of acid sphingomyelinase, and rapid lesion removal by caveolar endocyTosis, providing a mechanistic explanation for the muscle pathology associated with mutations in caveolae proteins.

Interaction of nickel and manganese in accumulation and localization in leaves of the Ni hyperaccumulators Alyssum murale and Alyssum corsicum
The genus Alyssum contains >50 Ni hyperaccumulator species; many can achieve >2.5% Ni in dry leaf. In soils with normal Mn levels, Alyssum trichome bases were previously observed to accumulate Ni andExpand
Pathogenesis of Aspergillus fumigatus and the kinetics of galactomannan in an in vitro model of early invasive pulmonary aspergillosis: implications for antifungal therapy.
This in vitro model of the human alveolus provides a strategy by which relationships among pathogenesis, immunological effectors, and antifungal drug therapy for invasive pulmonary aspergillosis may be further understood. Expand
Viability of the nonculturable Vibrio cholerae O1 and O139.
Not only do VBNC V cholerae O1 and O139 retain viability up to one year, but genes associated with pathogenicity are retained, along with chromosomal integrity. Expand
Ultrastructure of coccoid viable but non-culturable Vibrio cholerae.
Cell division in the smallest coccoid cells was observed, yielding daughter cells of equal size, whereas other coccoids revealed bleb-like, cell wall evagination, followed by transfer of nuclear material, as well as substrate responsive and antigenic. Expand
Pressure-induced depolymerization of spindle microtubules. III. Differential stability in HeLa cells
Surprisingly, the length and density of microtubules of the stem bodies and midbody of telophase cells appear unchanged by pressurization, while kinetochores appeared diffuse and were difficult to identify in sections of pressurized cells. Expand
Characterization of the dsDNA prophage sequences in the genome of Neisseria gonorrhoeae and visualization of productive bacteriophage
The data suggest that the genes similar to dsDNA lysogenic phage present in the gonococcus are generally conserved in this pathogen and that they are able to regulate the expression of other neisserial genes. Expand
