Published: November 2008

ObjectiveRecent evidence suggests that adiponectin may play a role in bone metabolism. Previous studies demonstrated that the adiponectin levels had a negative correlation with bone mineral density (BMD) in women. However, little is known about the relationship between adiponectin and BMD in men. The aim of this study was to determinate the relationship between the adiponectin levels and BMD in elderly men.DesignCross-sectional study including 92 healthy men aged 60–80 years.MethodsMain outcome measures were the adiponectin levels estimated by RIA and BMD at lumbar spine and femoral neck using dual energy X-ray absorptiometry.ResultsThe negative correlation between adiponectin and BMD at the spine was r=−0.209, (P<0.05) and at the femoral neck was r=−0.237, (P<0.001). These correlations disappeared after adjustment for body mass index (BMI). When stratified by BMI, the relationship between BMD and adiponectin remained significant in the subgroup of participants with BMI >27 kg/m2, but disappeared in men with BMI ≤27 kg/m2. In multiple regression analysis, adiponectin was a significant determinant of BMD at the spine, not at the femoral neck, in those with BMI >27.ConclusionBMD is negatively associated with the adiponectin levels in men older than 60 years and this relationship is greater in those men with BMI >27, which suggests a plausible connection between bone and fat tissue.

Published: November 2008

Objectives. This retrospective cohort analysis of children enrolled in the North Carolina Medicaid program compared the likelihood of restorative treatments and associated cumulative Medicaid expenditures for teeth with or without dental sealants.Methods. We assessed the dental experience of the cohort of 15 438 children from 1985 to 1992 on the basis of enrollment and claims files. We conducted regression analyses for outcomes (caries-related services involving the occlusal surface [CRSOs] of permanent first molars) and cumulative expenditures, controlling for characteristics of the child, the treating dentist, and the child's county of residence.Results. Overall, 23% of children received at least 1 sealant and 33% at least 1 CRSO. Sealants were effective in preventing CRSOs, although the degree of effectiveness was highest for children with the greater levels of CRSOs before sealant placement. Estimated cumulative Medicaid expenditures indicated expenditure savings from sealants within 2 years of application for children with 2 or more prior CRSOs.Conclusions. Sealant placement was associated with expenditure savings to Medicaid for certain high-risk children, so Medicaid and, more broadly, society will benefit by providing for sealant placement in these children.
Increasing Voluntary HIV Testing by Offering Oral Tests in Incarcerated Populations
Authors: Bauserman Robert L. , Ward Michael A. , Eldred Lois , Swetz Anthony 
Published: November 2008

Objectives. This study reports responses of incarcerated persons to voluntary blood and oral HIV testing. Methods. Males and females in local detention and juvenile justice facilities in Maryland (n = 1314) chose oral or blood testing and reported reactions to the oral HIV test. The relationship of demographics and HIV risk factors to test choice was examined. Results. Reactions to oral testing were very favorable; some participants reported that they would not otherwise have been tested. Participants who chose oral testing were more likely to be male and African American, but they did not differ from those who chose blood testing in most risk factors or in seroprevalence. Conclusions. Oral HIV testing in correctional settings may promote voluntary testing among persons who otherwise would refuse or avoid testing, especially among groups (males and African Americans) disproportionately affected by HIV.

Published: November 2008

This study focuses on the evaluation of the adequacy and sustainability of a constructed wetland (CW), with vertical flow (VF) design to treat a strongly coloured textile wastewater.
Secondly an accidental AO7 overloaded discharge (700 mg l−1) was studied. A set of three similar VFCW beds (3 × 1 m2), operating in series, allowed also the efficient treatment of the AO7 heavy loaded wastewaters. The treated effluent quality enables water reuse for irrigation purposes or within the process.

Published: November 2008

Injuries of extremities can be followed by various neuromuscular complications. Injury of peripheral nerves directly depended on the topographic localization of injury (fractures, cuts, contusions). The neuromuscular complications were diagnosed and under follow-up, based on clinical, x-ray, neurologic and neurophysiological findings. The timing of physical treatment and assessment of the necessary neurosurgical intervention depended on the obtained findings. After surgeries, we continued to apply physical treatment and rehabilitation.	The aim of the paper was to assess the significance of proper timing for surgery and adequate postoperative rehabilitation, as well as treatment results, depending on the extent of peripheral nerve injury. Material and methods: Based on the study condocted in the period from 2000-2002, most surgeries were done on the ulnar nerve (4 pts), median nerve (4 pts), radial nerve (3 pts), peroneal nerve (2 pts) and plexus brachialis (3 pts). Paresis and peripheral nerve paralysis, associated with sensibility disorders, predominated in clinical features. In most patients surgery was done during the first 3 - 6 months after injury. In early postoperative treatment positioning of extremities with electrotherapy were most often used in early postoperative treatment, Bioptron and dosed kinesitherapy. Depending on the neurophysiological findings, in later treatment stage we included electrostimulation, thermotherapy, kinesitherapy and working therapy, with the necessary application of static and dynamic orthroses. Study results showed that the success of treatment depended on the extent of injury, i.e. whether suture of liberalization of the nerve had been done, on the adequate timing of surgery, as well as on the adequate timing and application of physical therapy and rehabilitation. More rapid and complete functional recovery was achieved if the interval between injury and surgery was shorter, as well as physical therapy was applied early. Based on the analysis of the achieved results, we concluded that peripheral nerve lesions after fractures and contusions had better prognosis in relation to isolated sections of peripheral nerves, having in mind that these were mostly conductive block transfer and nerve stretching lesion, which do not leave sequelae after completed treatment After neurorrhaphies and applied therapy, motor and sensitive deficit mostly depended on good timing of surgery and continual physiatric treatment. It is also important to point out the significance of team-work among neurosurgeon, neurologist and physiatrist necessary in early detection and successful treatment of numerous sequelae and invalidity in patients with peripheral nerve lesions.

Published: November 2008

AbstractIn this paper a convenient and universal strategy for preparing nanoring arrays of different compositions based on a colloidal‐crystal‐template strategy is reported. Large‐area arrays of polystyrene, magnetite, Au, Si, magnetite nanoparticle/polystyrene and Au/polystyrene double‐layer composite nanorings are prepared. Many kinds of nanoring structures, including Fe3O4 nanoparticle/polystyrene and Au/polystyrene double‐layer nanorings, can be released from the substrates, resulting in free‐standing composite nanorings, which might be used as self‐assembly building blocks and ultrasensitive bio‐ and chemical sensors.

Published: November 2008

AbstractModerne Methoden zur Synthese von funktionellen Polymeren ermöglichen die direkte (Co‐)Polymerisation von Monomeren mit chemoselektiven Gruppen, die sich während der Polymerisation inert verhalten, aber in einem anschließenden Reaktionsschritt quantitativ in vielfältige funktionelle Gruppen umgewandelt werden können. Der Erfolg dieses Ansatzes beruht auf exzellenten Umsätzen unter milden Reaktionsbedingungen und der Orthogonalität der polymeranalogen Modifikationsreaktionen. Dieser Aufsatz gibt einen Überblick über verschiedene Klassen von Ausgangspolymeren mit reaktiven chemoselektiven Gruppen und ihre Herstellung durch (Co‐)Polymerisation geeigneter funktioneller Monomere. Darüber hinaus werden Aspekte der weiteren, polymeranalogen Umsetzung dieser Ausgangspolymere zu funktionellen Polymeren diskutiert.

AbstractHow low can you go? An FeII4 square was prepared by self‐assembly and exhibits both thermally induced and photoinduced spin crossover from a system with four high‐spin (HS) centers to one with two high‐spin and two low‐spin (LS) centers. The spin‐crossover sites are located on the same side of the square, and the spin transition and magnetic interactions (see picture) are synergistically coupled.magnified image

Published: November 2008

AbstractImprinting nanoparticles: Core‐shell bovine hemoglobin (BHb) imprinted magnetic nanoparticles (MNPs) with a mean diameter of 210 nm have been synthesized for the first time. The imprinted magnetic nanoparticles could easily reach the adsorption equilibrium and magnetic separation under an external magnetic field, thus avoiding problems related to the bulk polymer.magnified imageIn this work, the core‐shell bovine hemoglobin (BHb) imprinted magnetic nanoparticles (MNPs) with a mean diameter of 210 nm were synthesized for the first time. In this protocol, the initial step involved co‐precipitation of Fe2+ and Fe3+ in an ammonia solution. Silica was then coated on the Fe3O4 nanoparticles using a sol‐gel method to obtain silica shell magnetic nanoparticles. Subsequently, 3‐aminophenylboronic acid (APBA), which is the functional and cross‐linking monomer, and poly(APBA) thin films were coated onto the silica‐modified Fe3O4 surface through oxidation with ammonium persulfate in an aqueous solution in the presence or absence of protein. The morphology, adsorption, and recognition properties of the magnetic molecularly imprinted nanomaterial were investigated by transmission electron microscopy (TEM), X‐ray diffraction (XRD), thermogravimetric analysis (TGA), and vibrating sample magnetometer (VSM). Rebinding experiments were carried out to establish the equilibrium time and to determine the specific binding capacity and selective recognition. The protein adsorption results showed that poly(APBA) MIPs‐coated magnetic nanoparticles have high adsorption capacity for template protein BHb and comparatively low non‐specific adsorption. The imprinted magnetic nanoparticles could easily reach the adsorption equilibrium and magnetic separation under an external magnetic field, thus avoiding problems related to the bulk polymer. We believe that the imprinted polymer‐coated magnetic nanoparticles can be one of the most promising candidates for various applications, which include chemical and biochemical separation, cell sorting, recognition elements in biosensors, and drug delivery.

AbstractPlaying the sax: The enantioselective total syntheses of (−)‐ and (+)‐decarbamoyloxysaxitoxin (doSTX) and (+)‐saxitoxin (STX) are reported. A new methodology was developed for the synthesis of STXs, featuring discriminative reduction of the nitro group and NO bond in nitroisoxazolidine.magnified imageEnantioselective total syntheses of (−)‐ and (+)‐decarbamoyloxysaxitoxin (doSTX) and (+)‐saxitoxin (STX) were achieved. The characteristic spiro‐fused cyclic guanidine structure of STX was constructed by oxidation at the C4 position with IBX via an α‐iminium carbonyl intermediate and acid‐promoted cyclization of guanidine at the C5 position. A second‐generation methodology was developed for the synthesis of STX, featuring discriminative reduction of the nitro group and NO bond in nitroisoxazolidine. This approach provides efficient access to the key diamine intermediate for STXs.

Published: November 2008

AbstractA new series of ionic liquids composed of three cyclic sulfonium cations and four anions has been synthesized and characterized. Their physicochemical properties, including their spectroscopic characteristics, ion cluster behavior, surface properties, phase transitions, thermal stability, density, viscosity, refractive index, tribological properties, ion conductivity, and electrochemical window have been comprehensively studied. Eight of these salts are liquids at room temperature, at which some salts based on [NO3]− and [NTf2]− ions exhibit organic plastic crystal behaviors, and all the saccharin‐based salts display relatively high refractive indices (1.442–1.594). In addition, some ionic liquids with the [NTf2]− ion exhibit peculiar spectroscopic characteristics in FTIR and UV/Vis regions, whilst those salts based on the [DCA]− ion show lower viscosities (34.2–62.6 mPa s at 20 °C) and much higher conductivities (7.6–17.6 mS cm−1 at 20 °C) than most traditional 1,3‐dialkylimidazolium salts.

AbstractSupramolecular complexes consisting of a single‐stranded oligothymine (dTn) as the host template and an array of guest molecules equipped with a complementary diaminotriazine hydrogen‐bonding unit have been studied with electrospray‐ionization mass spectrometry (ESI‐MS). In this hybrid construct, a supramolecular stack of guest molecules is hydrogen bonded to dTn. By changing the hydrogen‐bonding motif of the DNA host template or the guest molecules, selective hydrogen bonding was proven. We were able to detect single‐stranded‐DNA (ssDNA)–guest complexes for strands with lengths of up to 20 bases, in which the highest complex mass detected was 15 kDa; these complexes constitute 20‐component self‐assembled objects. Gas‐phase breakdown experiments on single‐ and multiple‐guest–DNA assemblies gave qualitative information on the fragmentation pathways and the relative complex stabilities. We found that the guest molecules are removed from the template one by one in a highly controlled way. The stabilities of the complexes depend mainly on the molecular weight of the guest molecules, a fact suggesting that the complexes collapse in the gas phase. By mixing two different guests with the ssDNA template, a multicomponent dynamic library can be created. Our results demonstrate that ESI‐MS is a powerful tool to analyze supramolecular ssDNA complexes in great detail.
