Degenerate primers were used to amplify large fragments of reductive-dehalogenase-homologous (RDH) genes from genomic DNA of two Dehalococcoides populations, the chlorobenzene- and dioxin-dechlorinating strain CBDB1 and the trichloroethene-dechlorinating strain FL2. The amplicons (1,350 to 1,495 bp) corresponded to nearly complete open reading frames of known reductive dehalogenase genes and sh...

Abstract Polymerase chain reaction (PCR) primers were developed based on three known reductive dehalogenase (RDH) genes (pceA from Dehalospirillum multivorans, cprA from Desulfitobacterium dehalogenans, tceA from Dehalococcoides ethenogenes) and used to amplify bands of the appropriate size from a microbial consortium inoculated with contaminated estuarine sediment and enriched under sulfidogen...

In the vertebrate retina, the final step of visual chromophore production is the oxidation of 11-cis-retinol to 11-cis-retinal. This reaction is catalyzed by 11-cis-retinol dehydrogenases (11-cis-RDHs), prior to the chromophore rejoining with the visual pigment apo-proteins. The RDH5 gene encodes a dehydrogenase that is responsible for the majority of RDH activity. In humans, mutations in this ...

BACKGROUND Right dominant heart (RDH) in fetuses can occur with a number of cardiac as well as noncardiac anomalies. Analysis of the enlargement of the right cardiac chamber in the fetus remains a major challenge for sonographers and echocardiographers. The aim of this study was to report the experience with prenatal diagnosis of RDH in the fetuses over a 7-year period. METHODS Fetuses with p...

OBJECTIVES Biologics have shown greater efficacy than traditional treatments in patients with rheumatoid arthritis, although some cannot be administered on an outpatient basis. Day hospitalization requires the patient to attend the hospital for a few hours to receive those treatments that cannot be administered on an outpatient basis or that do not justify admission to hospital. Few studies hav...

Reversible Data hiding is a process of hiding information into a cover image. There are various techniques used for hiding secret data. Audio, video, image, text, and picture can be used as a cover medium in data hiding. In images, Reversible Data Hiding (RDH) is a method which is very helpful in the recovery of original cover after the inserted message is extracted. This vital method is broadl...

The resource dispersion hypothesis (RDH) offers a predictive model for how, in heterogeneous environments, some animals may form groups even without any direct benefits from doing so. Revilla (2003) levels a number of criticisms at the RDH, all of which we feel can be easily clarified or resolved (we address them in the order they appear in his critique). We argue that the RDH, despite its long...

We agree with Revilla [1] that the resource dispersion hypothesis (RDH) indeed lacks comprehensive evidence in any one specific case; however, this deficiency results from a lack of good tests, rather than from the failure of any tests [2]. Revilla’s claim that ‘we only need evidence against one of its assumptions and/or predictions to invalidate it’, is too sweeping. RDH cannot be rejected jus...
