During the cholera survey in Namdinh province (northern Vietnam) in July, 2010, one strain of Vibrio cholerae O139 was isolated from 7 environmental water samples positive for ctxA, toxR,VCO139 genes and named as V. cholerae O139, ND1 strain. This strain was lysogenic harbouring a genome similar to the filamentous phage fs1. The replicative form DNA of this phage (named as ND1-fs1, 6856 bp) was...
Complex I (CI, NADH ubiquinone oxidoreductase), the largest complex of the respiratory chain, is composed of 45 structural subunits, 7 of which are encoded in mtDNA. At least 10 factors necessary for holoenzyme assembly have been identified; however, the specific roles of most of them are not well understood. We investigated the role of NDUFAF3, NDUFAF4, C8orf38 and C20orf7, four early assembly...
A role for HflX in 50S-biogenesis was suggested based on its similarity to other GTPases involved in this process. It possesses a G-domain, flanked by uncharacterized N- and C-terminal domains. Intriguingly, Escherichia coli HflX was shown to hydrolyze both GTP and adenosine triphosphate (ATP), and it was unclear whether G-domain alone would explain ATP hydrolysis too. Here, based on structural...
This paper reports the isolation and characterization of a new o-nitrobenzaldehyde (ONBA)-degrading bacterium, Alcaligenes sp. ND1. ND1 degraded almost all ONBA (100 mg L(-1)) in M9 medium within 36 hours. The key enzyme(s) involved in the initial biodegradation was a constitutively intracellular enzyme(s). This bacterium has great potential utility for bioremediation.
We analyzed mutations in the mitochondrial ND1 gene to determine their association with clinicopathological parameters and postoperative recurrence of renal cell carcinoma (RCC) in Japanese patients. Among 62 RCC cases for which tumor pathology was confirmed by histopathology, ND1 sequencing revealed the presence of 30 mutation sites in 19 cases. Most mutations were heteroplasmic, with 16 of 19...
BACKGROUND Fasciola hepatica and F. gigantica are the causative agents of fasciolosis in domestic animals and humans. Based on the morphometric criteria, differential diagnosis between them is problematic. In addition, intermediate forms of Fasciola have been found in Iran, which makes the differentiation more difficult. The aim of the present study was to provide molecular evidence for the exi...
Sintered NdFeB magnets are relatively complex multiphase systems containing Nd2Fe14B matrix and about 15% of other intermetallics such as Nd1+εFe4BB4, Nd-oxides (Nd-rich phase), etc. Boron rich Nd1+εFe4B4 B forms in irregularly distributed heavily faulted grains of roughly the same size as those of the Nd2Fe14B phase [1]. The Curie temperature of this phase is 13K and, therefore, it is not ferr...
Mitochondrial DNA mutations are currently investigated as modifying factors impinging on tumor growth and aggressiveness, having been found in virtually all cancer types and most commonly affecting genes encoding mitochondrial complex I (CI) subunits. However, it is still unclear whether they exert a pro- or anti-tumorigenic effect. We here analyzed the impact of three homoplasmic mtDNA mutatio...
Mutations in fused in sarcoma (FUS), a DNA/RNA binding protein, are associated with familial amyotrophic lateral sclerosis (ALS). However, little is known about how ALS-causing mutations alter protein-protein and protein-RNA complexes and contribute to neurodegeneration. In this study, we identified protein arginine methyltransferase 1 (PRMT1) as a protein that more avidly associates with ALS-l...
