Background: The aim of this study was to evaluate root coverage of gingival recessions and to compare graft vascularization in smokers and non‐smokers.Methods: Thirty subjects, 15 smokers and 15 non‐smokers, were selected. Each subject had one Miller Class I or II recession in a non‐molar tooth. Clinical measurements of probing depth (PD), relative clinical attachment level (CAL), gingival recession (GR), and width of keratinized tissue (KT) were determined at baseline and 3 and 6 months after surgery. The recessions were treated surgically with a coronally positioned flap associated with a subepithelial connective tissue graft. A small portion of this graft was prepared for immunohistochemistry. Blood vessels were identified and counted by expression of factor VIII–related antigen–stained endothelial cells.Results: Intragroup analysis showed that after 6 months there a was gain in CAL, a decrease in GR, and an increase in KT for both groups (P <0.05), whereas changes in PD were not statistically significant. Smokers had less root coverage than non‐smokers (58.02% ± 19.75% versus 83.35% ± 18.53%; P <0.05). Furthermore, the smokers had more GR (1.48 ± 0.79 mm versus 0.52 ± 0.60 mm) than the non‐smokers (P <0.05). Histomorphometry of the donor tissue revealed a blood vessel density of 49.01 ± 11.91 vessels/200× field for non‐smokers and 36.53 ± 10.23 vessels/200× field for smokers (P <0.05).Conclusion: Root coverage with subepithelial connective tissue graft was negatively affected by smoking, which limited and jeopardized treatment results.
Review and update of paramphistomosis
Authors: Sanabria R. , Romero J. 
Published: June 2008

Abstract
Despite records of ruminal paramphistomes in Argentina dating back to the beginning of the XX century, in the last decade cases have increased in number with evidence of spreading to new geographical areas. This fact led us to carry out some studies in the last few years in order to enhance the poor availability of reports in South America, some of which are actually performed in our group. This paper reviews the characteristics of the life cycles and some aspects of the disease both at world and local level, and updates the latest paramphistome reports in domestic ruminants of Argentina.
First report of Mesocriconema xenoplax (Nematoda: Criconematidae) in Greece and first record of Viburnum sp. as a possible host for this ring nematode

Published: June 2008

Abstract
In 2005, root and soil samples were collected from the rhizosphere of Viburnum sp. plants in the yard of a house in Kifissia, Attica, Greece. The plants showed symptoms of yellowing and declining and all were dead within, approximately, one year. The roots were infected with the fungus Rosellinia necatrix. Several specimens of a ring nematode were recovered from soil and identified as Mesocriconema xenoplax based on morphological and morphometrical analysis of females. The nematode had been previously found on grapevines in Samos and Crete islands. This is the first report of M. xenoplax in Greece and the first record of Viburnum sp. as a host for this ring nematode. Additional information regarding distribution of this nematode in Greece is needed.
Application of fibre-optic rotational seismometer in investigation of seismic rotational waves
Authors: Jaroszewicz L. , Krajewski Z. 
Published: June 2008

AbstractApplication of a fibre-optic Sagnac interferometer as a rotational seismometer is presented in this paper. It is a new device which parameters (sensitivity equal to 4.3×10−8 rad/s for 2σ) are comparable with the parameters of typical mechanical rotational seismometers. However, a direct measurement of rotation without influence of linear motions for fibre-optic rotational seismometer designed it for a direct measurement of a ground rotation component. Experimental data obtained during simultaneous application of the above two types of sensors are also presented. Research of near-field seismic events, the amplitude of which has been identified in the range of 1.5×10−6 rad/s to 2×10−7 rad/s, shows directly that, so-called, seismic rotational waves exist independently of typical seismic waves generated during earthquakes.

Published: June 2008

Diabetes mellitus (DM) has been termed a “coronary disease equivalent”, yet data suggest that only those DM subjects with metabolic syndrome (MetS) are at increased coronary risk. Using data from the Dallas Heart Study, a large, probability-based population study, we assessed the individual and joint associations between MetS, DM and atherosclerosis, defined as coronary artery calcium (CAC) detected by electron-beam computerised tomography (EBCT) and abdominal aortic plaque (AAP) detected by magnetic resonance imaging. Among 2,735 participants, the median age was 44 years; 1,863 (68%) were non-white; 1,509 (55%) were women; 697 (25.5%) had MetS without DM; 53 (1.9%) had DM without MetS; and 246 (9.0%) had both DM and MetS. The prevalence of CAC increased from those with neither MetS nor DM (16.6%) to MetS only (24.0%) to DM only (30.2%) to both MetS and DM (44.7%) (ptrend <0.0001). The prevalence of CAC was higher in those with both DM and MetS versus either alone (p<0.0001). After adjustment, MetS and DM were each independently associated with CAC (odds ratio [OR] 1.4, 95% confidence intervals [CI] 1.1–1.8; OR 1.8, 95% CI 1.3–2.5, respectively). Compared with the group without DM or MetS, those with both MetS and DM had the most CAC (adjusted OR 2.3; 95% CI 1.6–3.2). All analyses of AAP yielded qualitatively similar results. In conclusion, both MetS and DM are independently associated with an increased prevalence of atherosclerosis, with the highest observed prevalence in subjects with both DM and MetS.
Preimplantation genetic diagnosis for complex chromosome rearrangements
Authors: Escudero T. , Estop A. , Fischer J. , Munne S. 
Published: June 2008

AbstractComplex chromosome rearrangements (CCR) are structural rearrangements that involve more than two breakpoints. The most common ones involve three chromosomes and three breakpoints, but double translocations can also occur. Theoretically, the potential for chromosome imbalance in the gametes of CCR carriers is higher than for simple translocations, and thus they are at an even higher risk of recurrent miscarriage. Preimplantation genetic diagnosis (PGD) has been shown to significantly reduce the risk of repeated pregnancy loss in translocation carriers, and thus it is well indicated for CCR. Here we describe different approaches for PGD of CCRs. After PGD of five couples carriers of CCR, only 6.4% of embryos were found normal or balanced, but the transfer of these six embryos into four couples, resulted in two pregnancies, one with normal non‐identical twins, and the other with a balanced karyotype. Thus the implantation rate was 50%, and the pregnancy per retrieval was 40%, with 0% spontaneous abortions and 0% unbalanced offspring. This compares favorably with a prior history of spontaneous abortions, unbalanced offspring, and low fertility. © 2008 Wiley‐Liss, Inc.
3D Computerized Model for Measuring Strain and Displacement of the Brachial Plexus Following Placement of Reverse Shoulder Prosthesis

Published: June 2008

AbstractThe aim of the present study was to develop a method for three‐dimensional (3D) reconstruction of the brachial plexus to study its morphology and to calculate strain and displacement in relation to changed nerve position. The brachial plexus was finely dissected and injected with contrast medium and leaden markers were implanted into the nerves at predefined places. A reverse shoulder prosthesis was inserted in a cadaveric specimen what induced positional change in the upper limb nerves. Computed tomography (CT) was performed before and after this surgical intervention. The computer assisted image processing package Mimics® was used to reconstruct the pre‐ and postoperative brachial plexus in 3D. The results show that the current interactive model is a realistic and detailed representation of the specimen used, which allows 3D study of the brachial plexus in different configurations. The model estimated strains up to 15.3% and 19.3% for the lateral and the medial root of the median nerve as a consequence of placing a reverse shoulder prosthesis. Furthermore, the model succeeded in calculating the displacement of the brachial plexus by tracking each implanted lead marker. The presented brachial plexus 3D model currently can be used in vitro for cadaver biomechanical analyses of nerve movement to improve diagnosis and treatment of peripheral neuropathies. The model can also be applied to study the exact location of the plexus in unusual upper limb positions like during axillary radiation therapy and it is a potential tool to optimize the approaches of brachial plexus anesthetic blocks.

AbstractOrganic field‐effect transistors incorporating planar π‐conjugated metal‐free macrocycles and their metal derivatives are fabricated by vacuum deposition. The crystal structures of [H2(OX)] (H2OX=etioporphyrin‐I), [Cu(OX)], [Pt(OX)], and [Pt(TBP)] (H2TBP=tetra‐(n‐butyl)porphyrin) as determined by single crystal X‐ray diffraction (XRD), reveal the absence of occluded solvent molecules. The field‐effect transistors (FETs) made from thin films of all these metal‐free macrocycles and their metal derivatives show a p‐type semiconductor behavior with a charge mobility (μ) ranging from 10−6 to 10−1 cm2 V−1 s−1. Annealing the as‐deposited Pt(OX) film leads to the formation of a polycrystalline film that exhibits excellent overall charge transport properties with a charge mobility of up to 3.2×10−1 cm2 V−1 s−1, which is the best value reported for a metalloporphyrin. Compared with their metal derivatives, the field‐effect transistors made from thin films of metal‐free macrocycles (except tetra‐(n‐propyl)porphycene) have significantly lower μ values (3.0×10−6–3.7×10−5 cm2 V−1 s−1).
Alternative translation start sites and hidden coding potential of eukaryotic mRNAs
Authors: Kochetov Alex V. 
Published: June 2008

AbstractIt is widely suggested that a eukaryotic mRNA typically contains one translation start site and encodes a single functional protein product. However, according to current points of view on translation initiation mechanisms, eukaryotic ribosomes can recognize several alternative translation start sites and the number of experimentally verified examples of alternative translation is growing rapidly. Also, the frequent occurrence of alternative translation events and their functional significance are supported by the results of computational evaluations. The functional role of alternative translation and its contribution to eukaryotic proteome complexity are discussed. BioEssays 30:683–691, 2008. © 2008 Wiley Periodicals, Inc.
The circadian clock system in the mammalian retina
Authors: Tosini Gianluca , Pozdeyev Nikita , Sakamoto Katsuhiko , Iuvone P. Michael 
Published: June 2008

AbstractDaily rhythms are a ubiquitous feature of living systems. Generally, these rhythms are not just passive consequences of cyclic fluctuations in the environment, but instead originate within the organism. In mammals, including humans, the master pacemaker controlling 24‐hour rhythms is localized in the suprachiasmatic nuclei of the hypothalamus. This circadian clock is responsible for the temporal organization of a wide variety of functions, ranging from sleep and food intake, to physiological measures such as body temperature, heart rate and hormone release. The retinal circadian clock was the first extra‐SCN circadian oscillator to be discovered in mammals and several studies have now demonstrated that many of the physiological, cellular and molecular rhythms that are present within the retina are under the control of a retinal circadian clock, or more likely a network of hierarchically organized circadian clocks that are present within this tissue.

Origin of β‐cells in regenerating pancreas
Authors: O'Neill Kathy E. , Eberhard Daniel , Tosh David 
Published: June 2008

AbstractThe origin of insulin‐expressing β‐cells in the adult mammalian pancreas is controversial. During normal tissue turnover and following injury, β‐cells may be replaced by duplication of existing β‐cells.1 However, an alternative source of β‐cells has recently been proposed based on neogenesis from a Ngn3‐positive population present in regenerating pancreatic ducts.2 The appearance of β‐cells from Ngn3‐positive progenitors is reminiscent of normal pancreas development, and Ngn3‐expressing cells isolated from regenerating pancreas can generate the full repertoire of endocrine phenotypes. The isolation and characterisation of the equivalent human progenitors may represent a significant step forward in the hunt for a cure for diabetes.

DNA microarrays in the clinic: infectious diseases
Authors: Mikhailovich Vladimir , Gryadunov Dmitry , Kolchinsky Alexander , Makarov Alexander A. , Zasedatelev Alexander 
Published: June 2008

AbstractWe argue that the most‐promising area of clinical application of microarrays in the foreseeable future is the diagnostics and monitoring of infectious diseases. Microarrays for the detection and characterization of human pathogens have already found their way into clinical practice in some countries. After discussing the persistent, yet often underestimated, importance of infectious diseases for public health, we consider the technologies that are best suited for the detection and clinical investigation of pathogens. Clinical application of microarray technologies for the detection of mycobacteria, Bacillus anthracis, HIV, hepatitis and influenza viruses, and other major pathogens, as well as the analysis of their drug‐resistance patterns, illustrate our main thesis.

Published: June 2008

AbstractBACKGROUND.This study was designed to evaluate the therapeutic effect of stereotactic radiosurgery (SRS) in patients aged ≥75 years who presented with brain metastasis.METHODS.The authors analyzed the data from 44 consecutive patients treated with SRS for ≥1 brain metastasis. The median age at the time of treatment for brain metastases was 79.3 years (range, 75 years–86 years), and the median Karnofsky performance status was 80 (range, 50–100). At the time of SRS, 31 patients were treated for a single metastasis, and the remaining 13 patients were treated for ≥2 lesions (n = 74 lesions). The median tumor volume was 1.2 cm3 (range, 0.007 cm3‐22.5 cm3). The median maximal and marginal doses were 36 grays (Gy) (range, 18.8 Gy‐48.2 Gy) and 20 Gy (range, 10 Gy‐24 Gy), respectively.RESULTS.Median survival was 7.3 ± 1.65 months (range, 1.6 months‐38.9 months) from the time of diagnosis of brain metastasis. Median survival of the patients with a single brain metastasis (10.1±1.92 months) was longer than that of the patients with ≥2 metastases (6.6±1.28 months) (P <.02). A single lesion was found to be an independent favorable prognostic factor (P±=±.017; odds ratio, 2.385 [95% confidence interval, 1.167‐4.874]) in univariate and multivariate analysis. Patients with nonsmall cell lung cancer fared worse than patients with other tumor types (survival of 6.5 ± 0.70 months vs 10.1 ± 2.33 months [P<.05]).CONCLUSIONS.SRS for patients aged ≥75 years with brain metastases is an effective and safe treatment modality that appears to improve survival, with outcomes that compare favorably with those reported for younger patients in an appropriately selected population.
