An active Neurospora-like assimilatory NADPH-nitrate reductase (EC 1.6.6.2), which can be formed in vitro by incubation of extracts of nitrate-induced Neurospora crassa mutant nit-1 with extracts of (a) certain other nonallelic nitrate reductase mutants, (b) uninduced wild type, or (c) xanthine oxidizing and liver aldehyde-oxidase systems was also formed by combination of the nit-1 extract with...
Using nitrate non-utilizing (nit) mutants, we determined vegetative compatibility groups (VCG) among strains of Beauveria bassiana representing strains indigenous to North America, isolated from diverse insect hosts, and strains that have been mass released for insect control. Genetic similarity among these strains was analyzed using random amplified polymorphic DNA (RAPD) markers. Our data rev...
The efficacy of cell-based therapy depends on the function and survival of transplanted cells, which have been suggested to be enhanced by spheroid formation. However, few attempts at spheroid generation from insulin-secreting cells, which may be used to treat type 1 diabetes, have been reported. We therefore developed spheroids from the mouse insulinoma cell line NIT-1 by using polydimethylsil...
Retraction The authors have retracted this article [1] due to the ethical misconduct of Karel Bezouska and misappropriation of data which fundamentally changes the main findings of the article. Specifically, the upper amino acid sequence in Figure 1 (by KB) in BMC Biotechnol 11:2 was incorrect, therefore Nit-ANigWT and Nit-ANigRec (nitrilase expressed in E. coli harbouring a nit gene from A. ni...
BACKGROUND The nucleotide-binding protein Fhit, among the earliest and most frequently inactivated proteins in lung cancer, suppresses tumor formation by inducing apoptosis. In invertebrates, Fhit is encoded as a fusion protein with Nit, a member of the nitrilase superfamily. In mice, the Nit1 and Fhit genes have nearly identical expression profiles. According to the Rosetta Stone hypothesis, i...
This paper gives an overview of recent transport developments taking place at the European scène. Particular attention is given to the impacts of technological dynamics as reflected in the new information technology (NIT). Against this background the paper gives an overview of results and findings from four major international conferences on the impact on NIT on spatial developments and transpo...
Low temperature plasma assisted nit riding treatments of 316 stainless steel produce a complex layer constituted by tow different metastable f.c.c. solid solution denoted ( γ N1 and γ N2 ). About the formation of these double layers, different hypothesis was proposed in the literature. For verifying these hypotheses, the effects of differentes conditions such as nit riding temperature, cleaning...
BACKGROUND Urinary tract infections (UTIs) are common bacterial infections dominated by lower UTI in women (LUTIW). Symptoms only are insufficient for diagnosis and accordingly, near patient diagnostic tests confidently confirming significant bacteriuria are desirable. The nitrite test (NIT) has low sensitivity, while bacterial and leukocyte counts disjunctively paired in urine sediment microsc...
BACKGROUND AND OBJECTIVE Unguided nasojejunal feeding tube insertion success rates are low. Controversy persists about how to safely and efficiently perform enteral nutrition (EN) in critically ill patients. This study explores an innovative blind nasointestinal tube (NIT) insertion method and compares nasogastric and nasointestinal feeding. METHODS Seventy critically ill patients admitted to...
Propionibacterium freudenreichii is widely used in Swiss-type cheese manufacture, where it contributes to flavour and eye development. It is currently divided into two subspecies, according to the phenotype for lactose fermentation and nitrate reduction (lac+/nit- and lac-/nit+ for P. freudenreichii subsp. shermanii and subsp. freudenreichii, respectively). However, the existence of unclassifia...
