[Ab] Resumo:Soft and pliable conductive polymer composites hold promise for application as bioelectronic interfaces such as for electroencephalography (EEG). In clinical, laboratory, and real-world EEG there is a desire for dry, soft, and comfortable interfaces to the scalp that are capable of relaying the µV-level scalp potentials to signal processing electronics. A key challenge is that most material approaches are sensitive to deformation-induced shifts in electrical impedance associated with decreased signal-to-noise ratio. This is a particular concern in real-world environments where human motion is present. The entire set of brain information outside of tightly controlled laboratory or clinical settings are currently unobtainable due to this challenge. Here we explore the performance of an elastomeric material solution purposefully designed for dry, soft, comfortable scalp contact electrodes for EEG that is specifically targeted to have flat electrical impedance response to deformation to enable utilization in real world environments. A conductive carbon nanofiber filled polydimethylsiloxane (CNF-PDMS) elastomer was evaluated at three fill ratios (3, 4 and 7 volume percent). Electromechanical testing data is presented showing the influence of large compressive deformations on electrical impedance as well as the impact of filler loading on the elastomer stiffness. To evaluate usability for EEG, pre-recorded human EEG signals were replayed through the contact electrodes subjected to quasi-static compressive strains between zero and 35%. These tests show that conductive filler ratios well above the electrical percolation threshold are desirable in order to maximize signal-to-noise ratio and signal correlation with an ideal baseline. Increasing fill ratios yield increasingly flat electrical impedance response to large applied compressive deformations with a trade in increased material stiffness, and with nominal electrical impedance tunable over greater than 4 orders of magnitude. EEG performance was independent of filler loading above 4 vol % CNF (< 103 ohms).

[Ab] Resumo:Aim of this study was to investigate the effect of long-time immersion of soft denture liners in 37°C water on viscoelastic properties. Six silicone-based and two acrylic resin-based soft denture liners were selected. Cylindrical specimens were stored in distilled water at 37°C for 6 months. Viscoelastic properties, which were instantaneous and delayed elastic displacements, viscous flow, and residual displacement, were determined using a creep meter, and analyzed with 2-way analysis of variance and Tukey's comparison (α=0.05). Viscoelastic properties and their time-dependent changes were varied among materials examined. The observed viscoelastic properties of three from six silicone-based liners did not significantly change after 6-month immersion, but those of two acrylic resin-based liners significantly changed with the increase of immersion time. However, the sum of initial instantaneous elastic displacement and delayed elastic displacement of two acrylic resin-based liners during 6-month immersion changed less than 10%, which might indicate clinically sufficient elastic performance.

[Ab] Resumo:OBJECTIVE: To examine the usefulness of room temperature vulcanizing (RTV) silicone rubber as a barrier material for cell exclusion zone assays. METHODS: We created barriers using three types of RTV silicone rubber with differing viscosities. We then assessed the adherence of these barriers to culture dishes and their ease of removal from the dishes. We tested the effect of the newly created barriers on the extracellular matrix (ECM) protein fibronectin by attaching and then removing them from fibronectin-coated culture dishes. We also conducted cell exclusion zone assays with MIO-M1 cells using this new barrier in order to measure cell migration. We used real time reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemical staining to measure the effect of fibronectin on MIO-M1 cell migration and the effect of migration (with fibronectin coating) on basic fibroblast growth factor (bFGF) expression in MIO-M1 cells. RESULTS: Of the three types of RTV silicon rubber tested, KE-3495-T was the best in terms of adherence to the dish and ease of removal from the dish. When barrier attachment and removal tests were performed, this rubber type did not have an effect on the fibronectin that coated the dish. In the cell exclusion assay, removal of the barrier revealed that a cell-free area with a distinct margin had been created, which allowed us to conduct a quantitative assessment of migration. Fibronectin significantly promoted the migration of MIO-M1 cells (P = 0.02). In addition, both real time RT-PCR and immunohistological staining indicated that bFGF expression in migrating MIO-M1 cells was significantly higher than that in non-migrating cells (P = 0.03). CONCLUSIONS: RTV silicone rubber can be used to create an effective barrier in cell exclusion zone assays and allows simple and low-cost multi-parametric analysis of cell migration.

[Ti] Título:A simple technique of intraocular lenses explantation for single-piece foldable lenses.

[Ab] Resumo:Foldable intraocular lenses (IOLs) are most commonly used in modern-day cataract surgery. Explantation of these IOLs is not frequently encountered, but sometimes extreme situations may demand the same. Commonly explantation is achieved by bisecting the IOL inside the anterior chamber with a cutter and delivering the pieces out one by one. This may require corneal wound extension with associated damage and endothelial loss leading to visual deterioration. We devised a simple, innovative IOL explantation technique utilizing a modified Alcon A cartridge and snare. This can successfully refold the IOL to be explanted inside the eye and deliver it out through the same wound. The device has limitations with very thick optic lenses, multipiece, and silicon IOLs. In conclusion, we describe a simple, innovative, and reproducible technique to explant almost any single piece IOL without compromising the original surgery and yielding very satisfactory outcomes.

[Ab] Resumo:BACKGROUND: Contour Profile Gel/MemoryShape breast implants consist of a textured silicone elastomer shell filled with silicone gel. The objective of this clinical study was to assess the safety and effectiveness of Contour Profile Gel/MemoryShape breast implants in women who were undergoing primary breast augmentation, primary breast reconstruction, or revision surgery (revision-augmentation or revision-reconstruction). METHODS: This was a prospective, open-label, multicenter clinical study involving Contour Profile Gel/MemoryShape breast implants in 955 female subjects, including 572 primary augmentation, 124 revision-augmentation, 190 primary reconstruction, and 69 revision-reconstruction subjects. Safety was assessed based on the incidence, severity, and method of resolution of all complications. Endpoints were examined on both a per-subject and a per-implant basis. RESULTS: For the primary augmentation, revision-augmentation, primary reconstruction, and revision-reconstruction cohorts, the Kaplan-Meier estimated 10-year cumulative incidence rates for the key complications at the subject level were as follows: Baker grade III/IV capsular contracture, 3.6 (primary augmentation), 15.5 (revision-augmentation), 14.3 (primary reconstruction), and 16.4 (revision-reconstruction) percent; infection, 0.7 (primary augmentation), 1.9 (revision-augmentation), 1.6 (primary reconstruction), and 2.9 (revision-reconstruction) percent; explantation with or without replacement, 9.2 (primary augmentation), 25.9 (revision-augmentation), 34.1 (primary reconstruction), and 49.0 (revision-reconstruction) percent; explantation with replacement with study device, 4.0 (primary augmentation), 10.8 (revision-augmentation), 16.7 (primary reconstruction), and 27.9 (revision-reconstruction) percent; and any reoperation, 22.3 (primary augmentation), 35.0 (revision-augmentation), 52.7 (primary reconstruction), and 59.7 (revision-reconstruction) percent. CONCLUSION: The results of this study demonstrate that Contour Profile Gel/MemoryShape breast implants are safe and effective for primary and revision breast augmentation and reconstruction for women at least 22 years old.

[Ab] Resumo:Because it is impossible to chemically analyze all relevant micropollutants, the implementation of bioanalytical tools is essential to estimate ecological risks of chemical mixtures in regular water-monitoring programs. The first tier of the Smart Integrated Monitoring (SIMONI) strategy, which was described in part I, is based on the combination of passive sampling and bioanalytical measurements. Bioassay responses are compared with effect-based trigger values (EBT), and an overall SIMONI score on all bioassay data was designed to indicate environmental risks. The present study is focused on analyzing the feasibility of the hazard identification tier by evaluating results of 45 field campaigns at sites with different pollution profiles near the city of Amsterdam. A Daphnia assay was performed in situ, while silicon rubber or polar organic chemical integrative sampler (POCIS) extracts were tested with 4 nonspecific (daphnids, algae, bacteria, and cell culture) and 10 specific (9 Chemical Activated Luciferase Gene Expression [CALUX] assays and antibiotics scan) bioassays. Sensitivity analyses demonstrated the relevance of 2 classification variables in the SIMONI score formula on all bioanalytical data. The model indicated increased risks for the ecosystem at surface waters in greenhouse areas and undiluted wastewater-treatment plant (WWTP) effluents. The choice of testing specific bioassays on either polar or nonpolar passive sampling extracts is cost-effective and still provided meaningful insights on micropollutant risks. Statistical analyses revealed that the model provides a relevant overall impact assessment based on bioassay responses. Data analyses on the chemically determined mixture toxic pressure and bioanalytical methods provided similar insights in relative risk ranking of water bodies. The SIMONI combination of passive sampling and bioanalytical testing appears to be a feasible strategy to identify chemical hazards. Environ Toxicol Chem 2017;36:2400-2416. © 2017 SETAC.

[Ab] Resumo:PURPOSE: To report the surgical results of canaliculorhinostomy for patients with distal canalicular obstruction and lacking a structurally functional lacrimal sac who would otherwise require a conjunctivodacryocystorhinostomy (CDCR) with Jones tube placement. DESIGN: Retrospective observational case series. METHODS: Setting: Single tertiary institution. PERIOD: November 1994 to June 2011. PATIENT POPULATION: Sixteen patients with canalicular obstruction at or beyond 8 mm from the punctum, with an absent or unidentifiable lacrimal sac. INTERVENTION: Patients underwent canaliculorhinostomy, whereby direct anastomosis of the canaliculi or common canaliculus to the nasal mucosa was performed. MAIN OUTCOME MEASURES: Anatomic and functional success. RESULTS: Our study comprised 16 patients with a mean age of 44.9 ± 21.9 years. Ten (62.5%) were female and 6 (37.5%) male. Mean duration of follow-up was 7.8 years. Causes of an absent or unidentifiable lacrimal sac included previous trauma (n = 8, 50.0%), previous dacryocystorhinostomy (n = 4, 25.0%), chronic dacryocystitis (n = 3, 18.8%), and previous dacryocystectomy (n = 1, 6.2%). Anastomoses between the upper and lower canaliculi and the nasal mucosa was performed in 6 patients, while that between the common canaliculus and nasal mucosa was performed in 10. Anatomic and functional success rates were 87.5% (n = 14) and 81.3% (n = 13), respectively. CONCLUSION: Canaliculorhinostomy has reasonable success rates and provides an effective surgical alternative for a group of patients in whom CDCR with Jones tube placement would otherwise have been indicated.

[Ab] Resumo:During many measurements it is important to account for possible changes in the gas-particle distribution of aerosols containing semi-volatile organic compounds (SVOCs). If denuders are combined with currently used personal air samplers, a simultaneous differential sampling of the gas and particle phase is possible. Here we analysed the transmission efficiency of denuders based on multi-channel silicone rubber traps (setup: 9 cm long glass liner (ID 4 mm), containing 22 parallel silicone rubber tubes (55 mm long, ID 0.3 mm, OD 0.5 mm)) with polystyrene latex (PSL) particles for different scenarios. n-Hexadecane, dimethyl phthalate and diethylene glycol gases were used to measure the time-dependent gas phase collection efficiency of a denuder. Additionally, the evaporation of n-hexadecane aerosol particles passing through the denuders was investigated. Our results showed high transmission efficiencies from 91 to 100% (variation coefficients 3.69-9.65%) for the denuders operated vertically at a flow rate of 0.5 l min . With regard to the gas phase collection efficiency, nonpolar n-hexadecane gas was trapped with higher efficiency (87% after 22 h) than dimethyl phthalate gas (27% after 22 h), while for highly polar diethylene glycol the gas phase collection efficiency was 50% after 2 h. Regarding the evaporation of aerosol particles, smaller particles and lower flow rates led to higher particle volume reduction inside the denuders. In conclusion, the tested denuders are suitable for determining the gas-particle partitioning of SVOC aerosols of nonpolar substances and show above 90% transmission for all tested particle sizes.

[Ab] Resumo:Silicone elastomer is a promising material for medical applications and is widely used for implants with blood and tissue contact. However, its strong hydrophobicity limits adhesion of tissue cells to silicone surfaces, which can impair the healing process. To improve the biological properties of silicone, a triggerless pulsed vacuum cathodic arc plasma deposition technique was applied to deposit titanium dioxide (TiO ) films onto the surface. Scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy and contact angle measurements were used for coating characterization. Deposited films were about 150nm thick and exhibited good adhesion to the underlying silicone substrate. Surface wettability and roughness both increased after deposition of the TiO layer. In addition, cell-biological investigations demonstrated that the in-vitro cytocompatibility of TiO -coated samples was greatly improved without impacting silicone's nontoxicity. For validation of use in medical devices, further investigations were conducted and demonstrated stability of surface properties in an aqueous environment for a period of 68days and the coating's resistance to several sterilization methods.

[Ab] Resumo:PURPOSE: To compare the anterior capsule contraction and intraocular lens (IOL) decentration among three types of IOL to determine the influence of haptic design on anterior capsule stability. METHODS: One hundred fifty patients were enrolled in this prospective, randomized study and 260 eyes underwent implantation of one of the following IOLs: modified L-haptic IOL (n = 74), modified C-haptic IOL (n = 97), or a plate-haptic IOL (n = 89). The area of the anterior capsule opening, IOL decentration, and capsule overlap were measured using retroillumination photospot 1 day and 2 months after cataract surgery. RESULTS: The area of capsule opening at postoperative day 1 was significantly different between the three IOLs ( < 0.01). All IOLs showed reduction of the anterior capsule opening from 1 day to 2 months after surgery, and greater reduction was shown in the modified C-haptic IOL ( < 0.001). At postoperative month 2, IOL decentration was significantly different between the IOLs and showed a positive correlation with the mean area reduction during month 2. CONCLUSIONS: The degree of anterior capsule contraction and IOL decentration in modified L-haptic IOLs were less than those in modified C-haptic IOLs and comparable to those in plate-haptic IOLs.
