Br J Surg. 2008 Sep 2;95(10):1239-1244 Authors: Smallwood L, Allcock R, van Bockxmeer F, Warrington N, Palmer LJ, Iacopetta B, Golledge J, Norman PE BACKGROUND:: Increased matrix metalloproteinase (MMP) 9 activity has been implicated in the formation of abdominal aortic aneurysm (AAA). The aim was to explore the association between potentially functional variants of the MMP-9 gene and AAA. METHODS:: The - 1562C > T and - 1811A > T variants of the MMP-9 gene were genotyped in 678 men with an AAA (at least 30 mm in diameter) and 659 control subjects (aortic diameter 19-22 mm) recruited from a population-based trial of Screening for AAA. Levels of MMP-9 were measured in a Random subset of 300 cases and 84 controls. The association between genetic variants (including haplotypes) and AAA was assessed by multivariable logistic regression. RESULTS:: There was no association between the MMP-9 - 1562C > T (odds ratio (OR) 0.70 (95 per cent confidence interval (c.i.) 0.27 to 1.82)) or - 1811A > T (OR 0.71 (95 per cent c.i. 0.28 to 1.85)) genotypes, or the most common haplotype (OR 0.81 (95 per cent c.i. 0.62 to 1.05)) and AAA. The serum MMP-9 concentration was higher in cases than controls, and in minor allele carriers in cases and controls, although the differences were not statistically significant. CONCLUSION:: In this study, the genetic tenden ...

Related Articles Identification of novel peptide agonists from a Random peptide library for a 5-oxo-ETE receptor, a receptor for bioactive lipids. J Pept Sci. 2008 Aug 27; Authors: Sasaki Y, Tsujii T, Takeda S, Obinata H, Izumi T, Yamada K, Katakai R A combinatorial peptide library contains an enormous combination of amino acid sequences and drug candidates, but an effective Screening strategy to identify a variety of bioactive peptides has yet to be established. In this article, a Random hexapeptide library was screened to identify novel peptide ligands for a 5-oxo-ETE receptor (OXER), which is a G-protein-coupled receptor for bioactive lipids, by using an OXER-Gi1alpha fusion protein. We successfully identified 2 hexapeptides-Ac-HMQLYF-NH(2) and Ac-HMWLYF-NH(2)-that exhibited agonistic activity. Although the corresponding affinities were relatively low (EC(50) values of 146 and 6.7 microM, respectively), the activities were confirmed by other independent cell-based assay methods, namely, intracellular calcium mobilization and cell chemotaxis. This study demonstrates that a combinatorial peptide library may be screened using a [(35)S]GTPgammaS binding assay with G-protein-coupled receptor (GPCR)-Galpha fusion proteins, in general, and that of peptide ligands can be obtained even for nonpeptide receptors.

Related Articles Detection of apoptosis in a rat model of focal cerebral ischemia using a homing peptide selected from in vivo phage display. J Control Release. 2008 Jul 19; Authors: Hong HY, Choi JS, Kim YJ, Lee HY, Kwak W, Yoo J, Lee JT, Kwon TH, Kim IS, Han HS, Lee BH Focal cerebral ischemia, known as stroke, is caused by a sudden interruption in the blood supply to the brain. We attempted to identify peptides that can home to ischemic stroke tissue and detect the apoptosis of cells. A phage library displaying Random peptides was screened for homing peptides to ischemic stroke tissue in a rat transient middle cerebral artery (MCA) occlusion model. After three rounds of in vivo Screening, a phage clone displaying the most frequently occurring CLEVSRKNC sequence was selected. The CLEVSRKNC-phage preferentially homed to ischemic stroke tissue after intravenous administration into the MCA occlusion rats. The fluorescein-labeled synthetic CLEVSRKNC peptide, but not a scrambled control peptide, homed to ischemic stroke tissue with a lack of homing to non-ischemic brain tissue. The CLEVSRKNC peptide co-localized with a portion of neuronal cells, rather than with astrocytes, undergoing apoptosis at the penumbra region of stroke lesions. In autoradiographic studies, the uptake of the (131)I-labeled CLEVSRKNC peptide into an ischemic lesion increased at the first day and peaked at the third day after the injury. These results demonstrate that ...

Related Articles Conditional variable importance for Random forests. BMC Bioinformatics. 2008;9:307 Authors: Strobl C, Boulesteix AL, Kneib T, Augustin T, Zeileis A BACKGROUND: Random forests are becoming increasingly popular in many scientific fields because they can cope with "small n large p" problems, complex interactions and even highly correlated predictor variables. Their variable importance measures have recently been suggested as Screening tools for, e.g., gene expression studies. However, these variable importance measures show a bias towards correlated predictor variables. RESULTS: We identify two mechanisms responsible for this finding: (i) A preference for the selection of correlated predictors in the tree building process and (ii) an additional advantage for correlated predictor variables induced by the unconditional permutation scheme that is employed in the computation of the variable importance measure. Based on these considerations we develop a new, conditional permutation scheme for the computation of the variable importance measure. CONCLUSION: The resulting conditional variable importance reflects the true impact of each predictor variable more reliably than the original marginal approach.

Related Articles A preliminary study on Screening prevalence of pervasive developmental disorder in schoolchildren in Iran. J Autism Dev Disord. 2008 Apr;38(4):759-63 Authors: Ghanizadeh A To study prevalence rates of pervasive developmental disorder (PDD) symptoms and differences between subtypes in school age Iranian children. A Random sample of 2,000 school age children from both genders was selected. A parent-completed, DSM-IV-referenced rating scale of PDD symptoms was used. About 1.9% of the sample obtained Screening cutoff scores for probable autistic disorder and 0.5 for probable asperger's disorder. The rate of probable PDD was not more in girls than the boys. The rate of suspected cases of PDD in Iran is very high and probable autistic disorder is not gender related. It shows the need for more consideration of PDD in the mental health programs planning.

Abstract   The aim of this study was to evaluate the effect of the Screening question phrasing on the 1-year prevalence figures of headache disorders, including migraine. Of a Random sample of 563 invited participants in the Nord-Trøndelag Health Survey 2006–2008 in Norway, 297 (53%) met to a face-to-face interview. There were 74.1% that reported having had headache during the last year, whereas only 31.0% stated that they had suffered from headache in the same period. The 1-year prevalence of migraine was 17.2% and of tension-type headache (TTH) 51.9%. Migraine was ten times more likely ( OR  = 9.96, 95% CI 4.75–20.91) among those who stated that they were headache sufferers than among those who were not. Only headache sufferers had chronic TTH or medication-overuse headache. Thus “Have you suffered from headache?” can be a useful Screening question in population-based questionnaire studies if the goal is to identify most migraineurs and almost all individuals with chronic headache.

The construction of metagenomic libraries has permitted the study of microorganisms resistant to isolation and the analysis of 16S rDNA sequences has been used for over two decades to examine bacterial biodiversity. Here, we show that the analysis of Random sequence reads (RSRs) instead of 16S is a suitable shortcut to estimate the biodiversity of a bacterial community from metagenomic libraries. We generated 10 010 RSRs from a metagenomic library of microorganisms found in human faecal samples. Then searched them using the program BLASTN against a prokaryotic sequence database to assign a taxon to each RSR. The results were compared with those obtained by Screening and analysing the clones containing 16S rDNA sequences in the whole library. We found that the biodiversity observed by RSR analysis is consistent with that obtained by 16S rDNA. We also show that RSRs are suitable to compare the biodiversity between different metagenomic libraries. RSRs can thus provide a good estimate of the biodiversity of a metagenomic library and, as an alternative to 16S, this approach is both faster and cheaper. ...

Abington Town Manager Phillip Warren has proposed pre-employment Screening and Random drug tests for all town employees. “Everybody should be able to walk into a town building and know that every employee is alcohol- and drug-free,” Warren said. The policy would allow an employee to be tested based on “reasonable suspicion.” “If a department head suspects someone is under the influence, they can request a test,” Warren said. He said the policy proposal will be presented at the next town meeting, which the selectmen scheduled for Oct. 27. The highway department has a drug-testing policy. Warren said a townwide policy would be included in negotiations for future union contracts. ...
