The reliability of postural balance measures in single and dual tasking in elderly fallers and non-fallers
(2008)BMC Musculoskeletal DisordersBackground The purpose of this study was to determine the reliability of a forceplate postural balance protocol in a group of elderly fallers and non-fallers. The measurements were tested in single and dual-task conditions, with and without vision. Methods 37 elderly (mean age 73 ± 6 years) community-dwellers were included in this study. All were tested in a single (two-legged stance) and in a dual-task (two-legged stance while ...Journal Article -
Reliability of movement control tests in the lumbar spine
(2007)BMC Musculoskeletal DisordersBackground Movement control dysfunction [MCD] reduces active control of movements. Patients with MCD might form an important subgroup among patients with non specific low back pain. The diagnosis is based on the observation of active movements. Although widely used clinically, only a few studies have been performed to determine the test reliability. The aim of this study was to determine the inter- and intra-observer reliability of ...Journal Article -
Ultra-wideband geo-regioning
(2008)EURASIP Journal on Advances in Signal ProcessingUltra-wideband (UWB) technology enables a high temporal resolution of the propagation channel. Consequently, a channel impulse response between transmitter and receiver can be interpreted as signature for their relative positions. If the position of the receiver is known, the channel impulse response indicates the position of the transmitter and vice versa. This work introduces UWB geo-regioning as a clustering and localization method ...Journal Article -
Bioconductor: open software development for computational biology and bioinformatics
(2004)Genome BiologyThe Bioconductor project is an initiative for the collaborative creation of extensible software for computational biology and bioinformatics. The goals of the project include: fostering collaborative development and widespread use of innovative software, reducing barriers to entry into interdisciplinary scientific research, and promoting the achievement of remote reproducibility of research results. We describe details of our aims and ...Journal Article -
Web-based analysis of the mouse transcriptome using Genevestigator
(2006)BMC BioinformaticsBackground Gene function analysis often requires a complex and laborious sequence of laboratory and computer-based experiments. Choosing an effective experimental design generally results from hypotheses derived from prior knowledge or experimentation. Knowledge obtained from meta-analyzing compendia of expression data with annotation libraries can provide significant clues in understanding gene and network function, resulting in better ...Journal Article -
The constancy of gene conservation across divergent bacterial orders
(2009)BMC Research NotesBackground. Orthologous genes are frequently presumed to perform similar functions. However, outside of model organisms, this is rarely tested. One means of inferring changes in function is if there are changes in the level of gene conservation and selective constraint. Here we compare levels of gene conservation across three bacterial groups to test for changes in gene functionality. Findings. The level of gene conservation for different ...Journal Article -
Gas emission during laparoscopic colorectal surgery using a bipolar vessel sealing device: A pilot study on four patients
(2008)Patient Safety in SurgeryBackground Dissection during laparoscopic surgery produces smoke containing potentially toxic substances. The aim of the present study was to analyze smoke samples produced during laparoscopic colon surgery using a bipolar vessel sealing device (LigaSure™). Methods Four consecutive patients undergoing left-sided colectomy were enrolled in this pilot study. Smoke was produced by the use of LigaSure™. Samples (5,5l) were evacuated from ...Journal Article -
Maintenance metabolism and carbon fluxes in Bacillus species
(2008)Microbial Cell FactoriesBackground Selection of an appropriate host organism is crucial for the economic success of biotechnological processes. A generally important selection criterion is a low maintenance energy metabolism to reduce non-productive consumption of substrate. We here investigated, whether various bacilli that are closely related to Bacillus subtilis are potential riboflavin production hosts with low maintenance metabolism. Results While B. ...Journal Article -
Structure and characterization of a novel chicken biotin-binding protein A (BBP-A)
(2007)BMC Structural BiologyBackground The chicken genome contains a BBP-A gene showing similar characteristics to avidin family genes. In a previous study we reported that the BBP-A gene may encode a biotin-binding protein due to the high sequence similarity with chicken avidin, especially at regions encoding residues known to be located at the ligand-binding site of avidin. Results Here, we expand the repertoire of known macromolecular biotin binders by ...Journal Article
