    Abstract: Previous studies have demonstrated that increased body mass index (BMI) is associated with decreased mortality in hemodialysis (HD) patients. However, the association between BMI and survival has not been well established in patients undergoing peritoneal dialysis (PD). The aim of the study was to determine the association between BMI and mortality in the PD population using the Clinical Research Center (CRC) registry for end-stage renal disease (ESRD) cohort in Korea. Methods Prevalent patients with PD were selected from the CRC registry for ESRD, a prospective cohort study on dialysis patients in Korea. Patients were categorized into four groups by quartiles of BMI. Cox regression analysis was used to calculate the adjusted hazard ratio (HR) of mortality with a BMI of quartile 2 (21.4 - 23.5 kg/m 2 ) as the reference. Results A total of 900 prevalent patients undergoing PD were included. The median follow-up period was 24 months. The multivariate Cox proportional hazard model showed that the lowest quartile of BMI was associated with higher mortality (HR 3.00,95% confidence interval (CI), 1.26 - 7.15). However, the higher quartiles of BMI were not associated with mortality compared with the reference category of BMI quartile 2 (Quartile 3: HR 1.11, 95% CI, 0.43 - 2.85, Quartile 4: H R 1.64,95% CI, 0.66 - 4.06) after adjustment for clinical variables. Conclusions Lower BMI was a significant risk factor for death, but increased BMI was not associated with mortality in Korean PD patients.

    Abstract: To compare the effects of platelet-rich plasma injection with those of dry needling on shoulder pain and function in patients with rotator cuff disease. Design: A single-centre, prospective, randomized, double-blinded, controlled study. Setting: University rehabilitation hospital. Participants: Thirty-nine patients with a supraspinatus tendon lesion (tendinosis or a partial tear less than 1.0 cm, but not a complete tear) who met the inclusion criteria recruited between June 2010 and February 2011. Intervention: Two dry needling procedures in the control group and two platelet-rich plasma injections in the experimental group were applied to the affected shoulder at four-week intervals using ultrasound guidance. Measurements: The Shoulder Pain and Disability Index, passive range of motion of the shoulder, a physician global rating scale at the six-month follow-up, adverse effects monitoring and an ultrasound measurement were used as outcome measures. Results: The clinical effect of the platelet-rich plasma injection was superior to the dry needling from six weeks to six months after initial injection ( P 〈 0.05). At six months the mean Shoulder Pain and Disability Index was 17.7 ± 3.7 in the platelet-rich plasma group versus 29.5 ± 3.8 in the dry needling group ( P 〈 0.05). No severe adverse effects were observed in either group. Conclusions: Autologous platelet-rich plasma injections lead to a progressive reduction in the pain and disability when compared to dry needling. This benefit is certainly still present at six months after treatment. These findings suggest that treatment with platelet-rich plasma injections is safe and useful for rotator cuff disease.

    Abstract: Sodium alginate (SA) hydrogel microparticles were simply obtained by using electrospinning method at diverse processing parameters such as polymer concentration, applied voltage, tip to collector distance (TCD), and type and amount of divalent cations (crosslinking and gelation agents). In the case of TCD, there is no significant on the morphological shape of SA hydrogel microparticle. On the contrary, the particle size was decreased with an increase in the applied voltage. But at a high applied voltage, the polydispersity of SA hydrogel microparticle was increased and broad range of particle sizes was observed. Nearly monodisperse microparticles were prepared at applied voltage of 10kV. We also obtained SA hydrogel microparticles by the exchange of sodium ions with divalent cations such as Sr 2+ and Ba 2+ , which presented uniform spherical shape, in comparison with that prepared using Ca 2+ .

    Abstract: The effects of solvents such as 1,1,2,2-tetrachloroethane (TCE) and tetrahydrofuran (THF) and other processing parameters of electrospinning on the spinnability of high molecular weight poly(N-vinyl carbazole) (PVCz) solution and morphological variations of the as-spun PVCz web were investigated. That is, electrospun PVCz webs with various dimensions and shapes were obtained by controlling the type and amount of solvent and processing parameters like applied voltage, tip to the collector distance, and solution concentration. In the cases of all parameters, the average diameter of fibres in PVCz web electrospun in TCE was finer than that in THF. In addition, minimum diameters of fibres were about 900 nm and 3 μ m for TCE and THF, respectively. In THF, PVCz fibres at high initial polymer concentration were not cylindrical but planar, which were similar with “ribbon” and nano-sized pores, resulting from the differences in evaporation rates and in the viscosities of the solvent and the solutions.

    Abstract: Adiponectin, one of the adipokines, has been implicated in the inflammatory process in patients with allergic rhinitis. The level of adiponectin is affected by immunotherapy. Considering the fact that adiponectin receptors (AdipoRs) mediate intracellular signaling events in response to the binding of adiponectin, the role of AdipoRs in healthy and allergic nasal mucosa should be determined. This study investigates the level of expression and distribution pattern of AdipoR1 and AdipoR2 in healthy, mild, and moderate/severe persistent allergic nasal mucosa to understand the role of adiponectin in allergic rhinitis. Methods The level of expression and distribution pattern of AdipoR1 and AdipoR2 were evaluated in healthy, mild, and moderate/severe persistent allergic nasal mucosa, using semiquantitative reverse-transcriptase–polymerase chain reaction (RT-PCR), immunohistochemistry, and Western blot analysis. Results AdipoR1 was expressed in healthy, mild, and moderate/severe persistent allergic nasal mucosa where it was commonly localized to the vascular endothelium. However, AdipoR2 was not expressed in any samples of nasal mucosa tested in the present study. Semiquantitative RT-PCR and Western blot analysis showed that the level of expression of AdipoR1 mRNA and protein was decreased in mild and moderate/severe persistent allergic nasal mucosa in comparison with healthy nasal mucosa, but not significantly different between mild and moderate/severe persistent allergic nasal mucosa. Conclusion These results indicate that AdipoR1 may play an important role in the pathogenesis of allergic nasal mucosa, suggesting a role for AdipoR1 in vascular dysfunction in mild and moderate/severe persistent allergic nasal mucosa.

    Abstract: To prepare fine and even poly(N-vinyl carbazole) (PVCz)/polystyrene (PS) blend webs, we performed a series of experiments varying processing parameters, including the type of solvent, PVCz/PS blend ratio, applied voltage, and tip to the collector distance (TCD). It was found that the morphology and the average diameter of PVCz/PS blend web were strongly correlated with electrospinning conditions. The morphologies of PVCz/PS blend webs were beaded or fine fibre structures, depending on the blend ratio of PVCz and PS. Increasing content of PS in the spinning solution tended to produce higher spinnability and the average diameter of electrospun web became smaller. The average diameter of the PVCz/PS blend web was slightly decreased with increasing applied voltage. In the case of TCDs, there was no significant effect on the PVCz/PS blend web morphologies but on increasing the TCD, the average diameter of the PVCz/PS blend webs slightly decreased.

    Abstract: The effects of solution temperature and molecular weight on the rheological responses of poly(vinyl alcohol) (PVA) semidilute solutions (13 g/dL- 19 g/dL) in dimethyl sulfoxide (DMSO) have been studied using PVA with two different number-average degrees of polymerization (P n ): 1700 and 4000. For the rheological experiments using dynamic shear, the PVA solution with a P n of 1700 showed rather simple Newtonian fluid behaviour, whereas that with P n of 4000 exhibited non-Newtonian shear thinning behaviour. Steady shear rheology experiments suggested that the lower P n PVA solutions were Newtonian fluids, which is consistent with the dynamic shear rheology results. However, an abrupt decrease of shear viscosity at high shear rates was observed for the higher P n PVA solutions at lower temperatures, such as 30 °C and 50 °C. At higher temperatures of 70 °C and 90 °C, the higher molecular weight PVA solutions exhibited simple shear thinning behaviour without any further complications of flow instability. The fact that temperature plays a critical role in controlling the observed flow instability of the PVA solutions in DMSO strongly suggests that there exist enhanced inter-chain interactions by hydrogen bonding of PVA chains beyond the chain entanglements, particularly for the higher P n PVA semidilute solutions at low temperatures. Therefore, it is important to consider both chain entanglements and hydrogen bonding interactions in order to process PVA solutions without causing undesirable flow instability.
