Elucidation of the ribonuclease a aggregation process mediated by 3D domain swapping: A computational approach reveals possible new multimeric structures
Authors: Cozza Giorgio , Moro Stefano , Gotte Giovanni 
Published: August 2007

AbstractBy lyophilization from 40% acetic acid solutions, bovine pancreatic ribonuclease A forms several three‐dimensional (3D) domain‐swapped oligomers: dimers, trimers, tetramers, pentamers, hexamers, and traces of high‐order oligomers, purifiable by cation‐exchange chromatography. Each oligomeric species consists of at least two conformers displaying different basicity density, and/or exposure of positive charges. The structures of the two dimers and one trimer have been solved. Plausible models have been proposed for a second RNase A trimer and four tetramers, but not all the models are certainly assignable to the tetramers purified. Further studies have also been made on the pentameric and hexameric species, again without reaching structurally clear‐cut results. This work is focused on the detailed modeling of the tetrameric RNase A species, using four different approaches to possibly clarify unknown structural aspects. The results obtained do not confirm the validity of one tetrameric model previously proposed, but allow the proposal of a novel tetrameric structure displaying new interfaces that are absent in the other known conformers. New details concerning other tetrameric structures are also described. RNase A multimers larger than tetramers, i.e., pentamers, hexamers, octamers, nonamers, up to dodecamers, are also modeled, with the proposal of novel domain‐swapped structures, and the confirmation of what had previously been inferred. Finally, the propensity of RNase A to possibly form high‐order supramolecular multimers is analyzed starting from the large number of domain‐swapped RNase A conformers modeled. © 2007 Wiley Periodicals, Inc.

Meta-analysis of holmium laser enucleation versus transurethral resection of the prostate for symptomatic prostatic obstruction
Authors: Tan A , Liao C , Mo Z , Cao Y 
Published: August 2007

Abstract

Background
Holmium laser enucleation (HoLEP) is an alternative to transurethral resection (TURP) of the prostate for symptomatic prostatic obstruction.

Methods
Randomized controlled trials comparing HoLEP and TURP were identified systematically using Medline, Embase and The Cochrane Library. Primary outcomes were peak urinary flow rate (Qmax), postvoid residual volume, symptom score and quality of life. Secondary outcomes were duration of operation, hospital stay, blood loss, catheterization time and adverse events.

Results
There was no statistically significant difference between HoLEP and TURP in terms of Qmax at 6 and 12 months' follow-up. HoLEP was associated with significantly less blood loss, a shorter catheterization time and a shorter hospital stay. TURP was associated with reduced operating time. The techniques were similar in terms of urethral stricture, stress incontinence, transfusion requirement and rate of reintervention.

Conclusion
HoLEP and TURP provide a similar improvement in Qmax. HoLEP, however, has several advantages over TURP, despite requiring more operating time. It is at least as safe as TURP in terms of adverse events.
Innovation and competitive advantages from the integration of strategic aspects with social and environmental management in European firms
Authors: Wagner Marcus 
Published: August 2007

AbstractThis paper analyses the nature and details of the association that the integration of social and environmental considerations with corporate strategy has for different competitive advantages and innovation activities at the firm level. Its objective is to answer the question as to whether a positive link exists between integration and the effects of environmental and social performance on these different dimensions of economic performance. The question of the specific form of this relationship is also raised. These questions are analysed using cluster analysis and regression models. Results are presented for four different dimensions of competitive advantage, and for two types of innovation activity. These raise the possibility that the process of integration is more important for bringing about a positive link than a resulting integration type.

Comparing the anatomical consistency of the posterior superior iliac spine to the iliac crest as reference landmarks for the lumbopelvic spine: A retrospective radiological study
Authors: McGaugh J.M. , Brismée J.M. , Dedrick G.S. , Jones E.A. , Sizer P.S. 
Published: August 2007

AbstractA palpation reference line coursing between the superior‐most aspect of the iliac crests has been reported to cross the L4 spinous process or L4/L5 intervertebral space in ∼80% of the population. Comparable data have not been defined for the line coursing between the posterior superior iliac spines (PSIS). The purpose of this study was to compare the anatomical consistency of the PSIS to the iliac crest as landmarks used for spinal palpation. One hundred computerized tomographic images were reviewed in a three‐dimensional setting. Two horizontal lines were constructed on each image: Line 1 representing the superior‐most aspect of the iliac crest and Line 2 representing the inferior margin of the PSIS. The vertical distance between each horizontal line and the inferior edge of its respective spinous process were measured. The PSIS corresponded to the S2 spinous process in 81% of subjects and the iliac crest to the L4 spinous process in 59% of subjects. Distance measures suggest that the PSIS was closer to S2 versus the iliac crest to L4 (t = 6.998; P < 0.01). The PSIS crossed S2 more frequently than the iliac crest crossed L4 (χ2 = 12.719, P ≤ 0.01). The study findings support the relationship between the PSIS, and the spinous process of S2 is more consistent when compared to the iliac crest and the spinous process of L4. The PSIS reference line may be used to find S2 as a reference standard in validity and reliability palpation studies in the lower lumbar spine. Clin. Anat. 20:819–825, 2007. © 2007 Wiley‐Liss, Inc.
Vertebral body shape variation in the thoracic and lumbar spine: Characterization of its asymmetry and wedging

Published: August 2007

AbstractThis study was designed to characterize the vertebral body (VB) shape, focusing on vertebral wedging, along the thoracic and lumbar spine, and to look for shape variations with relation to gender, age, and ethnicity. All thoracic and lumbar (T1–L5) dissected vertebrae of 240 individuals were measured and analyzed by age, gender, and ethnicity. A 3D digitizer was used to measure all VB lengths, heights, and widths, and their ratios were calculated. This study showed that the VB size was independent of age or ethnicity. VB left lateral wedging was found in most vertebrae of most individuals, yet systematically was absent in six vertebrae (T4, T8–T9, T11, L3–L4) with a greater tendency in females than males (∼92% vs. 86%). The VB was anteriorly wedged from T1 through L2 (peak at T7), nonwedged at L3, and posteriorly wedged at L4–L5 (peak at L5). VB width decreased from T1 to T4 and then increased toward L4–L5, so that the spinal configuration in the coronal plane resembled two pyramids of opposite directions, sharing an apex at T4. The inferior VB width was significantly greater than the superior width of both the same vertebra and the adjacent lower vertebra, indicating a trapezoidal shape of the VB and an inverted trapezoidal shape of the intervertebral space. In conclusion, these findings indicate that the human vertebra, in its normal condition, maintains its external dimensions with age, independent of gender or ethnic origin. Clinical and surgical implications of the unique thoracolumbar architecture are discussed. Clin. Anat. 21:46–54, 2008. © 2007 Wiley‐Liss, Inc.
Geographical classification of olive oils by the application of CART and SVM to their FT‐IR

Published: August 2007

AbstractThis paper reports the application of Fourier‐transform infrared (FT‐IR) spectroscopy to the geographical classification of extra virgin olive oils. Two chemometrical techniques, classification and regression trees (CART) and support vector machines (SVM) based on the Gaussian kernel and the recently introduced Euclidean distance‐based Pearson VII Universal Kernel (PUK), were applied to discriminate between Italian and non‐Italian and between Ligurian and non‐Ligurian olive oils. The PUK is applied in literature with success on regression problems. In this paper the mapping power of this universal kernel for classification was investigated. In this study it was observed that SVM performed better than CART. SVM based on the PUK provide models with a high selectivity and sensitivity (thus a better accuracy) as compared to those obtained using the Gaussian kernel. The wave numbers selected in the classification trees were interpreted demonstrating that the trees were chemically justified. This study also shows that FT‐IR spectroscopy associated with SVM and CART can be used to correctly discriminate between various origins of olive oils, demonstrating that the combination of techniques might be a powerful tool for supporting the claimed origin of olive oils.
