Strain N35(T) was isolated from surface-sterilized wheat roots and is a Gram-negative, aerobic, motile straight rod. Strain N35(T) tested oxidase-positive and catalase-negative and grew optimally at pH 7.0, 30 °C and in the absence of NaCl. 16S rRNA gene sequence analysis showed over 97 % sequence similarity to strains of the environmental species Acidovorax delafieldii, A. facilis, A. defluvii...

Acidovorax radicis N35, isolated from surface-sterilized wheat roots (Triticum aestivum), showed irreversible phenotypic variation in nutrient broth, resulting in a differing colony morphology. In addition to the wild-type form (rough colony type), a phenotypic variant form (smooth colony type) appeared at a frequency of 3.2 × 10(-3) per cell per generation on NB agar plates. In contrast to th...

PURPOSE To determine normative values for pattern-reversal electroretinogram (PERG) in healthy adult volunteers according to the standard protocol recommended by the International Society for Clinical Electrophysiology of Vision-ISCEV. METHODS Participants were 30 healthy volunteers (15 males) with ages from 18 to 61 years (mean= 30.8 +/- 8.7 yrs.; median= 29.5 yrs). Inclusion criteria were: ...

Quorum sensing auto-inducers of the N-acyl homoserine lactone (AHL) type produced by Gram-negative bacteria have different effects on plants including stimulation on root growth and/or priming or acquirement of systemic resistance in plants. In this communication the influence of AHL production of the plant growth promoting endophytic rhizosphere bacterium Acidovorax radicis N35 on barley seedl...

PURPOSE Comparison of quality of life (QoL) and side effects in a randomized trial for early hyperbaric oxygen therapy (HBOT) after radiotherapy (RT). METHODS AND MATERIALS From 2006, 19 patients with tumor originating from the tonsillar fossa and/or soft palate (15), base of tongue (1), and nasopharynx (3) were randomized to receive HBOT or not. HBOT consisted of 30 sessions at 2.5 ATA (15 m...

BACKGROUND The bilateral absence of the cortical N20 median-nerve somatosensory evoked potential (SSEP) is a strong predictor of poor outcome from coma. However, when N20s are present, accurate prognostication is challenging. Here, we investigated the potential for later SSEP components to help disambiguate outcome in these cases. METHODS In a retrospective review of data from two intensive c...

OBJECTIVE To evaluate the reliability and validity of a new, disease-specific quality-of-life measure for patients with head and neck cancer: the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire--QLQ-H&N35. DESIGN Cross-sectional study using questionnaire data and medical chart review. SETTING Academic tertiary care otolaryngology clinic. PA...

Nonproducer cells transformed by Kirsten sarcoma virus (KiSV) or Abelson murine leukemia virus (A-MuLV) were infected with N- or NB-tropic helper viruses to rescue the defective transforming virus. The titer of the transforming viruses was determined on NIH/3T3 fibroblast-like cells and cell-free filtrates of virus stock were inoculated into newborn Fv-1nn mice. Friend, Moloney, and Rauscher gr...

BACKGROUND Patient-reported outcome (PRO) instruments are important tools for monitoring disease activity and response to treatment in clinical trials and clinical practice. In recent years, there have been movements away from traditional pen-and-paper PROs towards electronic administration. When using electronic PROs (ePROs), evidence that respondents complete ePROs in a similar way to their p...
