Authors: Nada A. N. , Debnath U. K. , Robinson D. A. , Jordan C. 
Published: September 2010

We describe the clinical outcome of a technique of surgical augmentation of chronic massive tears of the rotator cuff using a polyester ligament (Dacron) in 21 symptomatic patients (14 men, seven women) with a mean age of 66.5 years (55.0 to 85.0). All patients had MRI and arthroscopic evidence of chronic massive tears. The clinical outcome was assessed using the Constant and Murley and patient satisfaction scores at a mean follow-up of 36 months (30 to 46). The polyester ligament (500 mm × 10 mm) was passed into the joint via the portal of Neviaser, medial to the tear through healthy cuff. The two ends of the ligament holding the cuff were passed through tunnels made in the proximal humerus at the footprint of the insertion of the cuff. The ligament was tied with a triple knot over the humeral cortex. All the patients remained free from pain (p < 0.001) with improvement in function (p < 0.001) and range of movement (p < 0.001). The mean pre-operative and post-operative Constant scores were 46.7 (39.0 to 61.0) and 85.4 (52.0 to 96.0), respectively (p < 0.001). The mean patient satisfaction score was 90%. There were two failures, one due to a ruptured ligament after one year and the other due to deep-seated infection. The MR scan at the final follow-up confirmed intact and thickened bands in 15 of 17 patients. This technique of augmentation gives consistent relief from pain with improved shoulder movement in patients with symptomatic massive tears of the rotator cuff.

Published: September 2010

We evaluated the outcome in a series of patients with recurrent patellar dislocation who had either medial transfer of the tibial tuberosity and lateral release or an isolated lateral release as the primary treatment. The decision to use one or other procedure was based on a pre-operative distance between the tibial tuberosity to the trochlear groove (TTTG) of less than 10 mm to include the tibial tuberosity transfer in addition to the lateral release. Between April 2002 and December 2006, 49 patients (63 knees) underwent one of these procedures. A total of 35 patients (46 knees) was evaluated at a mean of 38 months (13 to 71) post-operatively. Medial transfer of the tibial tuberosity was performed in 33 knees and isolated lateral release in the remaining 13. Evaluation included the International Knee Documentation Committee (IKDC), the Kujala and the Short-form 36 scores. From the tibial tuberosity group 23 knees also underwent radiological examination at follow-up. There were further episodes of patellar dislocation in six of the 46 knees available for review. Further dislocation was noted in five of 33 knees (15.2%) in the tibial tuberosity transfer group and in one of 13 knees (7.7%) in the lateral release group. The mean subjective IKDC score was 80.4 (sd 11.6), the mean Kujala score 88 (sd 8.2) and the mean objective IKDC score was 79% normal and 21% nearly normal. The mean post-operative TTTG distance in the tibial tuberosity transfer group was 8.9 mm (3.2 to 15.7) compared with the mean pre-operative value of 16.8 mm (12.2 to 24.4).

Published: September 2010

Intra-articular resection of bone with soft-tissue balancing and total knee replacement (TKR) has been described for the treatment of patients with severe osteoarthritis of the knee associated with an ipsilateral malunited femoral fracture. However, the extent to which deformity in the sagittal plane can be corrected has not been addressed. We treated 12 patients with severe arthritis of the knee and an extra-articular malunion of the femur by TKR with intra-articular resection of bone and soft-tissue balancing. The femora had a mean varus deformity of 16° (8° to 23°) in the coronal plane. There were seven recurvatum deformities with a mean angulation of 11° (6° to 15°) and five antecurvatum deformities with a mean angulation of 12° (6° to 15°). The mean follow-up was 93 months (30 to 155). The median Knee Society knee and function scores improved from 18.7 (0 to 49) and 24.5 (10 to 50) points pre-operatively to 93 (83 to 100) and 90 (70 to 100) points at the time of the last follow-up, respectively. The mean mechanical axis of the knee improved from 22.6° of varus (15° to 27° pre-operatively to 1.5° of varus (3° of varus to 2° of valgus) at the last follow-up. The recurvatum deformities improved from a mean of 11° (6° to 15°) pre-operatively to 3° (0° to 6°) at the last follow-up. The antecurvatum deformities in the sagittal plane improved from a mean of 12° (6° to 16°) pre-operatively to 4.4° (0° to 8°) at the last follow-up. Apart from varus deformities, TKR with intra-articular bone resection effectively corrected the extra-articular deformity of the femur in the presence of antecurvatum of up to 16° and recurvatum of up to 15°.
Image-guided navigation in orthopaedic trauma
Authors: Leung K. S. , Tang N. , Cheung L. W. H. , Ng E. 
Published: September 2010

Fluoronavigation is an image-guided technology which uses intra-operative fluoroscopic images taken under a real-time tracking system and registration to guide surgical procedures. With the skeleton and the instrument registered, guidance under an optical tracking system is possible, allowing fixation of the fracture and insertion of an implant. This technology helps to minimise exposure to x-rays, providing multiplanar views for monitoring and accurate positioning of implants. It allows real-time interactive quantitative data for decision-making and expands the application of minimally invasive surgery. In orthopaedic trauma its use can be further enhanced by combining newer imaging technologies such as intra-operative three-dimensional fluoroscopy and optical image guidance, new advances in software for fracture reduction, and new tracking mechanisms using electromagnetic technology. The major obstacles for general and wider applications are the inability to track individual fracture fragments, no navigated real-time fracture reduction, and the lack of an objective assessment method for cost-effectiveness. We believe that its application will go beyond the operating theatre and cover all aspects of patient management, from pre-operative planning to intra-operative guidance and postoperative rehabilitation.

Published: September 2010

We investigated the role of a functional brace worn for four months in the treatment of patients with an acute isolated tear of the posterior cruciate ligament to determine whether reduction of the posterior tibial translation during the healing period would give an improved final position of the tibia. The initial and follow-up stability was tested by Rolimeter arthrometry and radiography. The clinical outcome was evaluated using the Lysholm score, the Tegner score and the International Knee Documentation Committee scoring system at follow-up at one and two years. In all, 21 patients were studied, 21 of whom had completed one-year and 17 a two-year follow-up. The initial mean posterior sag (Rolimeter measurement) of 7.1 mm (5 to 10) was significantly reduced after 12 months to a mean of 2.3 mm (0 to 6, p < 0.001) and to a mean of 3.2 mm (2 to 7, p = 0.001) after 24 months. Radiological measurement gave similar results. The mean pre-injury Lysholm score was normal at 98 (95 to 100). At follow-up, a slight decrease in the mean values was observed to 94.0 (79 to 100, p = 0.001) at one year and 94.0 (88 to 100, p = 0.027, at two years). We concluded that the posterior cruciate ligament has an intrinsic healing capacity and, if the posteriorly translated tibia is reduced to a physiological position, it can heal with less attentuation. The applied treatment produces a good to excellent functional result.
Chromatin regulators: weaving epigenetic nets
Authors: Hernández-Muñoz Inmaculada 
Published: September 2010

AbstractIn multicellular organisms differentiated cells must maintain their cellular memory, which will be faithfully inherited and maintained by their progeny. In addition, these specialized cells are exposed to specific environmental and cell-intrinsic signals and will have to appropriately respond to them. Some of these stimuli lead to changes in a subset of genes or to a genome-wide reprogramming of the cells that will remain after stimuli removal and, in some instances, will be inherited by the daughter cells. The molecular substrate that integrates cellular memory and plasticity is the chromatin, a complex of DNA and histones unique to eukaryotes. The nucleosome is the fundamental unit of the chromatin and nucleosomal organization defines different chromatin conformations. Chromatin regulators affect chromatin conformation and accessibility by covalently modifying the DNA or the histones, substituting histone variants, remodeling the nucleosome position or modulating chromatin looping and folding. These regulators frequently act in multiprotein complexes and highly specific interplays among chromatin marks and different chromatin regulators allow a remarkable array of possibilities. Therefore, chromatin regulator nets act to propagate the conformation of different chromatin regions through DNA replication and mitosis, and to remodel the chromatin fiber to regulate the accessibility of the DNA to transcription factors and to the transcription and repair machineries. Here, the state-of-the-art of the best-known chromatin regulators is reviewed.
Propeptides as modulators of functional activity of proteases
Authors: Demidyuk Ilya V. , Shubin Andrey V. , Gasanov Eugene V. , Kostrov Sergey V. 
Published: September 2010

AbstractMost proteases are synthesized in the cell as precursor-containing propeptides. These structural elements can determine the folding of the cognate protein, function as an inhibitor/activator peptide, mediate enzyme sorting, and mediate the protease interaction with other molecules and supramolecular structures. The data presented in this review demonstrate modulatory activity of propeptides irrespective of the specific mechanism of action. Changes in propeptide structure, sometimes minor, can crucially alter protein function in the living organism. Modulatory activity coupled with high variation allows us to consider propeptides as specific evolutionary modules that can transform biological properties of proteases without significant changes in the highly conserved catalytic domains. As the considered properties of propeptides are not unique to proteases, propeptide-mediated evolution seems to be a universal biological mechanism.
Identification of diatom isolates from the Gulf of Gdańsk: testing of species identifications using morphology, 18S rDNA sequencing and DNA barcodes of strains from the Culture Collection of Baltic Algae (CCBA)
Authors: Pniewski Filip , Friedl Thomas , Latała Adam 
Published: September 2010

Abstract
Eighteen strains of diatoms isolated from different phytoplankton and microphytobenthic assemblages in the Gulf of Gdańsk (Baltic Sea, Poland) and maintained at the Culture Collection of Baltic Algae (CCBA) were investigated for their species identifications. The latter were tested by phylogenetic analyses of nearly full 18S rDNA sequences as well as through sequence comparisons of 5.8S+ITS2 rDNA fragments for use as DNA barcode. The planktonic species were readily identified as a member of the Cyclotella meneghiniana species complex and Skeletonema marinoi, respectively, by both 18S phylogenies and DNA barcoding. In contrast, for the pennate diatom strains the suitability of DNA sequence comparisons for species identification appeared to be still rather limited. Only one strain could be identified to the species level (Navicula gregaria) using DNA barcodes, and no closest relative barcode sequences were available for the other strains. The 18S rDNA phylogenies supported species identification for only one strain (Bacillaria cf. paxillifera). In all other pennate strains identification was only possible to the genus level. Because for most species identified by morphology no closest neighbouring 18S rDNA sequences were available, the CCBA strains may serve as references to represent certain species which have been well characterized by morphology, 18S rDNA sequence analyses and DNA barcodes. Relatively high 18S rDNA differences between pairs of strains of Fistulifera saprophila and Navicula perminuta indicated that each species may represent a complex of several cryptic species. In contrast, the five isolates of Nitzschia microcephala had identical sequences as well as the two isolates of Nitzschia cf. fonticola. With the addition of new species to the 18S rDNA phylogeny of pennate raphid diatoms, the monophyly of the genera Fistulifera, Haslea and Navicula s.str. were confirmed, while Nitzschia appeared paraphyletic. The traditional family Naviculaceae was paraphyletic, in agreement with previous phylogenetic studies.

Published: September 2010

Abstract
The aim of this study was to assess the ability of bottom sediments to release or accumulate phosphorus. Ex situ experiments with the use of undisturbed sediment cores were done in 11 lakes situated in the Cybina River valley (Wielkopolska, Poland). Phosphorus release was observed both in aerobic and anaerobic conditions, however greater values were noted in the latter ones. Maximum values reached 41.4 mg m-2 d-1 P and 12.2 mg m-2 d-1 P in anaerobic and aerobic conditions, respectively.
The variability in concentrations of chosen nitrogen and phosphorus forms in the Oder River estuary in 1999-2002
Authors: Tórz Agnieszka , Nędzarek Arkadiusz 
Published: September 2010

Abstract
The Oder River creates one of the largest estuaries in Poland. The estuary can be divided into three zones, each with a different hydrochemical regime: the Pomeranian Bay (salt water habitat), the Szczecin Lagoon (brackish water habitat), the Oder River up to the Widuchowa section (transitional environment - brackish and typical freshwater). The Pomeranian Bay was characterized by the lowest concentration of nutrients throughout the research series in comparison to the other regions. It had a low nitrogen to phosphorus proportion and the highest stability of variability in total nitrogen concentration. The Szczecin Lagoon was characterized by a higher concentration of nutrient loads in comparison to the Pomeranian Bay, by a lower nitrogen and phosphorus proportion than the Oder waters, and by the high stability of variability of concentrations of mineral nitrogen and total nitrogen. As the "nutrient trap" for the Oder estuarine system, the Oder River, with its highest nutrient concentration, is characterized by the highest stability of variability of total nitrogen concentration.
A comparison between the water quality of the main tributaries to three submontane dam reservoirs and the sediment quality in those reservoirs
Authors: Szarek-Gwiazda Ewa , Mazurkiewicz-Boroń Grażyna 
Published: September 2010

Abstract
Nutrients, pH, and organic matter were determined in water samples collected from the Raba River above Dobczyce Reservoir (meso-eutrophic), from the Dunajec River above Czorsztyn Reservoir (mesotrophic), and Rożnów Reservoir (eutrophic), and in the bottom sediments of the reservoirs. The river waters were alkaline (pH 7.2-9.2). In the Raba River and Dunajec River, the ranges of nutrients and organic matter contents were similar (without significant differences) (in mg dm-3; N-NO3 0.5-2.5, N-NH4 0.2-2.0, N-NO2 0.004-0.040, N-tot 1.1-5.6, PO4 0.02-0.58, P-tot 0.03-1.9, while BOD5 1.6-9.9 mg dm-3 O2, COD 2.1-30.4 mg dm-3 O2). The pH of reservoir sediments was from neutral to slightly alkaline (6.9-7.6). The sediments were mineral and were characterized by a low amount of nutrients (N-tot 0.04-0.36%, P-tot 0.007-0.185%) and organic matter (expressed as LOI 3.0-10.6%, TOC 0.9-3.3%). Nutrient (except P-tot) and organic matter contents in the sediments of three reservoirs were similar (without significant differences) and did not reflect the trophic state of the reservoirs.
The bottom sediments of Lake Uzarzewskie - a phosphorus source or sink?
Authors: Kowalczewska-Madura Katarzyna , Gołdyn Ryszard , Dondajewska Renata 
Published: September 2010

Abstract
Phosphorus release from bottom sediments studied in two zones of Lake Uzarzewskie differing in depth and water oxygenation displayed seasonal and spatial variability. The experiments indicated that the lake receives considerable internal loading, especially from the deeper, anaerobic, rarely-mixed part of the lake. Meanwhile, the shallow zone situated in the 0-3 m depth range, could be a sink for phosphorus during spring and a source during other seasons of the year. The total loading of phosphorus from the bottom sediments was over 950 kg year-1 P, and 83% of this amount originated from the deeper part of the lake. The mean release from this part was 24.89 mg m-2 d-1 P and the maximum in fall was 35.4 mg m-2 d-1 P.

Authors: Ellis Scott J. , Williams Benjamin R. , Wagshul Adam D. , Pavlov Helene , Deland Jonathan T. 
Published: September 2010

Background: Stage IV posterior tibial tendon insufficiency is characterized by the presence of valgus talar tilt in the setting of a flatfoot deformity which results from attenuation of the deltoid ligament. Correcting valgus tilt at the time of flatfoot reconstruction may prevent future collapse and the need for joint sacrificing procedures. The purpose of this study was to report the intermediate-term results of patients who underwent deltoid ligament reconstruction using a peroneus longus tendon transfer. Materials and Methods: Five patients (mean age, 67 years ± 5.3 years) who underwent flatfoot reconstruction along with deltoid ligament reconstruction using a peroneus longus autograft were evaluated at a mean of 8.9 ± 1.7 years after surgery. The FAOS, SF-36v2, and VAS surveys were administered. The correction of valgus talar tilt was determined with weightbearing radiographs of the ankle. Ankle range of motion along with standing hindfoot alignment was assessed. Results: The postoperative average FAOS and SF-36v2 were 68.3 (range, 55.2 to 85.0) and 75.7 (range, 40 to 92), respectively. The valgus talar tilt improved from 7.7 degrees preoperatively to 2.1 degrees postoperatively. Mean ankle range of motion was 47 degrees (range, 40 degrees to 55 degrees). Mean hindfoot alignment was 4 degrees valgus (range, 1 degree varus to 8 degrees valgus). Conclusion: Deltoid ligament reconstruction using a peroneus longus tendon transfer was a useful technique for reducing tibiotalar tilt in the setting of stage IV flatfoot deformity. Correction and function were maintained at intermediate-term followup. Level of Evidence: IV, Retrospective Case Series
Patrimoine antique et émotion révolutionnaire : la construction des nations italienne et allemande en 1848 au miroir de l’Antiquité
Authors: Robert-Boissier Béatrice 
Published: September 2010

«La politique absorbe ici désormais tout ce qui est archéologie.» Cette citation, tirée d’une lettre écrite par Wilhem Henzen, philologue allemand et secrétaire de l’Institut de correspondance archéologique fondé à Rome en 1829, à Eduard Gerhard, lui-même ancien secrétaire et fondateur de l’institut, témoigne de l’envahissement politique du monde scientifique lors des révolutions de 1848, catalyseur de l’élan vers l’unité nationale en Allemagne comme en Italie. Dans le cadre de l’évolution des études de l’Antiquité, de son accès au statut de science et de la conscience politique et nationale croissante, l’Alterthumswissenschaft devient un moyen d’exprimer ses positions politiques et d’établir des analogies avec le présent, notamment durant les événements de 1848. Dans ce contexte se distinguent les figures de deux antiquisants, l’archéologue et numismate Giuseppe Fiorelli (1821-1896) à Naples et l’historien de l’Antiquité et épigraphiste Theodor Mommsen (1817-1903) à Kiel, dont le travail scientifique et l’action politique se montrent indissolublement liés en 1848 et dont l’oeuvre est le miroir des préoccupations historiques et politiques de l’époque. À travers l’analyse comparative de leur carrière scientifique et de leur engagement politique, on peut voir en effet qu’ils font appel à l’Antiquité pour éclairer un présent qui offre bien des similitudes entre l’Allemagne et l’Italie. L’étude de deux articles, l’un paru dans le journal Il Tempo du 10 mars 1848 et l’autre dans le
Schleswig Holsteinische Zeitung du 24 avril 1848, permet de mettre en lumière deux méthodes différentes de mise au présent de l’Antiquité.
Une émotion patrimoniale exemplaire : la destruction et la reconstruction du pavillon d’Art contemporain de Milan
Authors: Piscaglia Sabrina 
Published: September 2010

El pabellón de arte contemporáneo de Milano, obra del arquitecto Ignazio Gardella, fue destrozado por une bomba de la mafia, durante la noche del 29 Julio 1993. La pérdida de este edificio que existía desde mas de cincuenta años, suscitó una reacción fuerte y sorprendente. Las autoridades, los intelectuales y la población de la cuidad, se comprometieron activamente desde el 30 julio, hasta el fin de las obras el 16 abril 1996, en la reconstrucción al «idéntica». La comunidad entera expresó un sentimiento patrimonial muy fuerte, trabajó para que vuelva el
PAC, ahora símbolo de une ciudad que no se somete a la violencia. Explicar este fenómeno no es simple. Las respuestas pueden ser buscadas por una parte en el contexto histórico y cultural milanese que permitió la creación del PAC, y por otra parte el en contexto cultural, social y político de Italia de 1993. El caso del PAC es paradigmatico en la cultura italiana, porque revela la realidad de Milano y la de Italia entera en la época del desastre. Este traumatismo permite desarollar una nueva mirada sobre los temas de la identidad, y del patrimonio.
Écrire « son » patrimoine : De nouvelles lectures locales du territoire
Authors: Lasmènes Marie-Ange 
Published: September 2010

El enfoque etnológico permite tratar la cuestión del patrimonio a partir de prácticas sociales, observando una verdadera dínamica social. Entre todas estas prácticas o estas maneras de hacer patrimonio, la escritura sería una manera de oficializar unos discursos sobre un territorio y su pasado, y también una manera de mostrarlo, usando la exposición de componientes patrimoniales cada vez más diversos. La querencia para el lugar, y el sentimiento de pertenencia, provocan la patrimonialización. Se forman grupos que se hacen mediadores del pasado. La escritura tal como se practica asegura una mediación en la que se define y se institucionaliza lo que es «património».
