Use of Fibrin Glue in Hepatic Trauma (1988)

We evaluated the efficacy and safety of fibrin glue (FG) made with highly concentrated human fibrinogen and clotting factors in achieving hemostasis of superficial and deep hepatic injuries. Experimentally produced hepatic injuries were produced in 12 adult mongrel dogs and hemostatically sealed with FG. Half of the dogs each received two penetrating hepatic injuries consisting of a large laceration and a deep stab wound through the liver; the remaining dogs underwent resection of a large segment of the left lobe of the liver. Hemostasis was achieved by applying FG into and over the bleeding wounds; hepatic arterial occlusion was not used. Complete hemostasis was achieved in all animals before skin closure. One dog from each group was re-explored and the liver specimens harvested for gross and microscopic examination at postoperative intervals of 12 hours, 24 hours, and 2, 3, 6, and 8 weeks. There were no cases of intra-abdominal infection, abscess formation, or bile fistulae. Histologic examination demonstrated a thickened capsule containing fibrous connective tissue and neovascular proliferation; there were no signs of local or systemic toxicity. One dog died on postoperative day 1 from rebleeding from the hepatic injury; all other dogs survived without complications. We conclude that FG provides effective hemostasis of superficial and deep hepatic injuries, and has good systemic and local compatibility. Its use in surgery for hepatic trauma may lead to less intraoperative blood loss and transfusion requirements, as well as a reduced need for major hepatic resection to control hemorrhage.
Development and application of a real-time monitoring and feedback system for deep inspiration breath hold based on external marker tracking (2006)

Respiration can cause tumor movements in thoracic regions of up to . To minimize motion effects several approaches, such as gating and deep inspiration breath hold (DIBH), are still under development. The goal of our study was to develop and evaluate a noninvasive system for gated DIBH (GDIBH) based on external markers. DIBH monitoring was based on an infrared tracking system and an in-house-developed software. The in-house software provided the breathing curve in real time and was used as on-line information for a prototype of a feedback device. Reproducibility and stability of the breath holds were evaluated without and with feedback. Thirty-five patients undergoing stereotactic body radiotherapy (SBRT) performed DIBH maneuvers after each treatment. For 16 patients dynamic imaging sequences on a multislice CT were used to determine the correlation between tumor and external markers. The relative reproducibility of DIBH maneuvers was improved with the feedback device ( without versus with feedback). The correlation between tumor and marker was good (Pearson correlation coefficient ). The regression slopes showed great intersubject variability but on average the internal margin in a DIBH treatment situation could be theoretically reduced by with the feedback device. DIBH monitoring could be realized in a noninvasive manner through external marker tracking. We conclude that reduction of internal margins can be achieved with a feedback system but should be performed with great care due to the individual behavior of target motion.
Effect of Lipid Oxidation Products on Blood Coagulation (1975)

Pure fatty acids in buffered aqueous suspension were allowed to autoxidise for up to 4 days. At intervals, lipid-free extracts were tested for effect on coagulation. 1-day extracts accelerated recalcification and RVV times, but products after 2-4 days oxidation showed progressive inhibition in these tests, and prolonged the P. T. and P. T. T. Addition of extracts to phospholipid altered its activity, and preparations of phospholipid extracted with an without antioxidant had different activity. In the absence of phospholipid, oxidation products had a threefold effect on thrombin generation in plasma: I), delay in appearance of thrombin; 2). increase in amount of thrombin formed; 3). less rapid neutralisation of thrombin. After fractionation of extracts by T. L. C. all these activities appeared in the most polar fration, which had the highest content of lipid peroxides. Thromboplastin generation tests showed that extracts delayed the formation of Xa, but increased the amount formed. Pre-formed Xa was strongly inhibited by oxidation products, but inhibition of thrombin was slight and could be abolished by glutathione. The presence of oxidation products in phospholipids could affect their activity in in vitro tests, and such products could also be involved in pathological coagulation in vivo.

Exploring Practical Limitations of Joint Routing and Scheduling for TSN with ILP (2018)

IEEE 802.1Q networks with extensions for time-sensitive networking aim to enable converged networks. Converged networks support hard-real time communication services in addition to the currently supported services classes. Real-time communication in these networks requires routes and schedules for the real-time transmissions. We present a formulation in the integer linear programming (ILP) framework which models the joint routing and scheduling problem for flows of periodic real-time transmissions in converged TSN networks. In the joint routing and scheduling problem, both routes and schedules for real-time transmissions are computed in one step, i.e. we do not schedule over predefined routes. We explore the practical limitations of this approach by evaluating the runtime of problem instances with widely varying parameters with a state-of-the-art ILP solver. The observed solver runtimes indicate the qualitative impact of the number of real-time flows, the size of the network, the transmission frequency of real-time transmissions, and the network topology.
Oxygen Ion Conduction in Bulk and Grain Boundaries of Nominally Donor‐Doped Lead Zirconate Titanate ( PZT ): A Combined Impedance and Tracer Diffusion Study (2015)

Oxygen ion conduction in Nd 3+ ‐doped Pb(Zr x Ti 1− x )O 3 ( PZT ) was investigated by impedance spectroscopy and 18 O‐tracer diffusion with subsequent secondary ion mass spectrometry ( SIMS ) analysis. Ion blocking electrodes lead to a second relaxation feature in impedance spectra at temperatures above 600°C. This allowed analysis of ionic and electronic partial conductivities. Between 600°C and 700°C those are in the same order of magnitude (10 −5 –10 −4 S/cm) though very differently activated (2.4 eV vs. 1.2 eV for ions and electron holes, respectively). Oxygen tracer experiments showed that ion transport mainly takes place along grain boundaries with partly very high local ionic conductivities. Numerical analysis of the tracer profiles, including a near‐surface space charge zone, revealed bulk and grain‐boundary diffusion coefficients. Calculation of an effective ionic conductivity from these diffusion coefficients showed good agreement with conductivity values determined from impedance measurements. Based on these data oxygen vacancy concentrations in grain boundary and bulk could be estimated. Annealing at high temperatures caused a decrease in the grain‐boundary ionic conductivity and onset of additional defect chemical processes near the surface, most probably due to cation diffusion.
Determination of the Temperature Effect on Glycerol Nitration Processes Using the HYSYS Predictions and the Laboratory Experiment (2014)

Determinations of the temperature effect on glycerol nitration processes have been done with two methods: the HYSYS predictions and the laboratory experiment. The aim of this study was to compare prediction method and laboratory experiment method. The highest equilibrium conversion from HYSYS predictions was obtained in the range of equilibrium temperature of 10 to 20 °C. The laboratory experiments also described that nitration of glycerol with nitric acid should be carried out at reaction temperature of 10 to 20 °C. HYSYS that was used to predict the results of experiments in the laboratory can reduce the laboratory work with minimize the range of operating conditions studied. HYSYS exactly predict temperature of nitration of glycerol. The difference in conversion between two methods due to the equipment that was used in the experiments, procedure of experiments and the accuracy of analysis.
Augmenting deformable part models with irregular-shaped object patches (2012)

The performance of part-based object detectors generally degrades for highly flexible objects. The limited topological structure of models and pre-specified part shapes are two main factors preventing these detectors from fully capturing large deformations. To better capture the deformations, we propose a novel approach to integrate the detections from a family of part-based detectors with patches of objects that have irregular shape. This integration is formulated as MAP inference in a Conditional Random Field (CRF). The energy function defined over the CRF takes into account the information provided by an object patch classifier and the object detector, and the goal is to augment the partial detections with missing patches, and also to refine the detections that include background clutter. The proposed method is evaluated on the object detection task of PASCAL VOC. Our experimental results show significant improvement over a base part-based detector (which is among the current state-of-the-art methods) especially for the deformable object classes.
Structural determination of triterpenic acids in Prunellae Spica by fast atom bombardment tandem mass spectrometry (2008)

Five triterpenic acids as marker compounds were extracted and isolated from Prunellae Spica by column chromatography and reversed-phase high-performance liquid chromatography (HPLC), and their purity was determinated by HPLC (purity ). Molecular weight and elemental compositions of the five marker compounds were determined by fast atom bombardment high-resolution mass spectrometry (FAB-HRMS). The structural determination of the five marker compounds was carried out fast atom bombardment collision-induced dissociation tandem mass spectrometry (FAB-CID-MS/MS). The collision-induced dissociation (CID) of protonated molecules and deprotonated molecules produced diverse product ions due mainly to retro Diels-Alder reaction (RDA), dehydration and decarboxylation. Moreover, the CID-MS/MS spectra of the ions were observed charge-remote fragmentation (CRF) patterns. On the basis of interpretation of CID-MS/MS spectra, structural elucidation of triterpenic acids isolated from Prunellae Spica was clearly performed.
Automated design of FFT/IFFT processors for advanced telecom applications (2006)

The paper presents an automated environment for the generation of high performance fast Fourier transform (FFT/IFFT) macrocells. It is based on circuit-level VHDL and system-level C++ models of a parametric cascade architecture supporting different types of arithmetic. Moreover it is able to generate various test signals and to carry out a rapid processor accuracy analysis changing both architecture parameters and type of arithmetic. After high-level analysis a VHDL database is generated ready for logic synthesis and gate-level design and test. As case studies, the generation of FFT/IFFT cells for multi carrier wireless (UWB) and wireline (xDSL) communication is presented.
Phononic crystal metamaterials for frequency tuneable microfluidic functions using surface acoustic waves (2010)

This paper reports upon the use of novel phononic metamaterial structures to programme complex fluidic functions, actuated by surface acoustic waves (SAW), into a disposable microchip. We illustrate the application of the technique by demonstrating microcentrifugation for particle concentration and separation in microlitre droplets, showing a specific example using blood. SAW technologies have previously been used to concentrate particles using asymmetric wave propagation, although this is performed directly on an expensive piezoelectric wafer, limiting their application in diagnostics. The technique introduced here will provide a tool-box of diagnostic functions with their specific phononic structures to be integrated in a lab-on-a-chip.
[Clinical application of a large flow-through venous flap]. (2016)

To investigate the clinical effects of a large flow-through venous flap.Between January 2012 and January 2015,this flap was used in 9 patients with upper limb injury to reconstruct artery defect and large skin and soft tissue defect. The donor sites were covered with free skin grafts. The skin and soft tissue defects size ranged from 7.0 cm × 10.0 cm to 9.5 cm × 18.0 cm (average 9.2 cm× 12.0 cm).The flaps size ranged from 9.0 cm × 12.0 cm-11.5 cm × 20.0 cm (average 10.3 cm × 13.5 cm).Except 2 cases of small area necrosis occurred in the distal end of the flap, which healed after dressing change; the other 7 flaps survived completely. The donor wounds healed primarily. Postoperative patients were followed up for 12-26 months (mean 14.5 months). Flap appearance, texture and thickness were similar to the surrounding normal tissue. According to the sensory function evaluation standard formulated by the British Medical Research Council in 1954,the result of skin flap sensory evaluation was assessed as S2 in two cases,S3 in four cases,S3 in three cases, with excellent and good rate as 77.8％.According to the assessment standard for upper limb function issued by Chinese Medical Association of hand surgery, the limb function were assessed as excellent in 6 cases, good in 2 cases, poor in 1 case, with the excellent and good rate as 88.9％.The large flowthrough venous flap has the advantages of simple operation, minimal donor site morbidity and satisfactory appearance. It is a feasible method to repair the wound at upper limb with artery defect.
Reconfigurable and dual-polarization folded reflectarray antenna (2012)

This paper proposes a novel version of folded reflectarray antenna that allows a full electronic reconfigurability of the radiation pattern. The reconfigurability is obtained adopting an elementary cell on the main reflector able to provide at the same time the required phase-shift to the incident field and the necessary twist of the incident polarization. Since in many applications an antenna with dual-polarization operation is required, the proposed design allows the reflectarray to manage at the same time two orthogonal linear polarizations in two adjacent frequency bands. This achievement is obtained by replacing the polarizing grid, as typically adopted, with a dualband and dual-polarized FSS. As a proof of concept, two test antennas have been designed, manufactured and tested.

Unconventional, Laser Based OLED Material Direct Patterning and Transfer Methods (2011)

Organic light emitting diode (OLED) displays have a number of desirable features such as high contrast and brightness, wide color range, thin structure and light weight, among others.(Hirano et al. 2007) OLED displays have several manufacturing requirements such as large area scalability and an increasing push towards smaller feature sizes, tighter feature shape control, high yield and low cost. However, traditional lithography and thermal evaporation deposition techniques have significant disadvantages, including the need for masks that are typically difficult to make to the required specifications at a reasonable price. The conventional vacuum deposition and photolithographic patterning methods are well developed for inorganic microelectronics. However, organic electronics materials are chemically incompatible with corrosive etchants, resists and developers used in conventional integrated circuit (IC) processing. In practice, conventional IC fabrication processes are subject to limitations, in that they are multi-step, involve high processing temperatures, toxic waste and are therefore expensive. Furthermore, the increasing size of electronic devices such as displays poses great difficulty in adapting standard microfabrication processes, including lithographic patterning. (Zschieschang et al. 2003, Ko et al. 2007) Therefore, there is a strong need to develop a novel process instead of complex modification of conventional vacuum deposition and photolithography based processes. OLED display manufacturing employs direct write techniques for patterning the various materials. Examples of OLED material direct write technologies include ink jet printing (Hashimoto et al, 2006, Gohda et al. 2002, Lee et al. 2002,, Kobayshi et al. 2002, Shirasaki et al. 2004, Fleuster et al. 2004, Lee et al. 2005, Saafir et al. 2005) screen printing (Shinar et al. 2007, Lee et al. 2009) and laser induced forward transfer (LIFT) (Hirano et al. 2007, Pique et al. 1999, Suh et al. 2003, Willis et al. 2005, Kyrkis et al. 2006). As described in a recent review on OLED RGB patterning, success of an OLED patterning scheme depends on the material type, device design, pixel array pattern, display format, substrate size, placement accuracy, process TACT-time, and defect density. The type of material and OLED architecture largely determine which type of RGB patterning can be applied. Other factors determining the
Zwitterionic Cellulose Carbamate with Regioselective Substitution Pattern: A Coating Material Possessing Antimicrobial Activity (2015)

A polyzwitterion is synthesized by regioselective functionalization of cellulose possessing a uniform charge distribution. The positively charged ammonium group is present at position 6, while the negative charge of carboxylate is located at positions 2 and 3 of the repeating unit. The molecular structure of the biopolymer derivative is proved by NMR spectroscopy. This cellulose-based zwitterion is applied to several support materials by spin-coating and characterized by means of atomic force microscope, contact angle measurements, ellipsometry, and X-ray photoelectron spectroscopy. The coatings possess antimicrobial activity depending on the support materials (glass, titanium, tissue culture poly(styrene)) as revealed by confocal laser scanning microscopy and live/dead staining.
Mapping molecular binding by means of conformational dynamics measurements (2018)

Protein-protein interactions are key in virtually all biological processes. The study of these interactions and the interfaces that mediate them play a key role in the understanding of biological function. In particular, the observation of protein-protein interactions in their dynamic environment is technically difficult. Here two surface analysis techniques, dual polarization interferometry and quartz crystal microbalance with dissipation monitoring, were paired for real-time mapping of the conformational dynamics of protein-protein interactions. Our approach monitors this dynamics in real time and <i>in situ</i>, which is a great advancement within technological platforms for drug discovery. Results agree with the experimental observations of the interaction between the TRIM21α protein and circulating autoantibodies <i>via</i> a bridging bipolar mechanism. This work provides a new chip-based method to monitor conformational dynamics of protein-protein interactions, which is amenable to miniaturized high-throughput determination.
Caracterización botánica de variedades de caña de azúcar mediante marcadores fenotípicos y moleculares (2020)

El Programa de Mejoramiento Genético de la Caña de Azúcar (PMGCA) de la Estación Experimental Agroindustrial Obispo Colombres (EEAOC) genera continuamente nuevas variedades de caña de azúcar, especialmente para laprovincia de Tucumán, Argentina. Una precisa identificación varietal es esencial para proteger los derechos de propiedadintelectual de los nuevos cultivares. Para caracterizar tres cultivares de caña de azúcar recientemente liberados por elPMGCA, en este trabajo se utilizaron marcadores moleculares TRAP y SSR (de sus siglas en inglés de ?Target RegionAmplified Polymorphism? y ?Simple Sequence Repeat?, respectivamente), en combinación con marcadores fenotípicos propuestos por la Unión Internacional para la Protección de las Obtenciones Vegetales (UPOV). Se utilizaron cinco combinaciones de cebadores TRAP y cinco pares de cebadores SSR. Los productos de amplificación se separaron mediante electroforesis en geles de poliacrilamida en condiciones desnaturalizantes. Para la caracterización fenotípica se utilizaron los nueve descriptores obligatorios de la UPOV. Las bandas y los datos morfológicos se transformaron en matrices binarias de 0 y 1, se calculó la similitud y se generaron los dendrogramas utilizando el análisis UPGMA (de sus siglas en inglés de ?Unweighted Pair?Group Method using Arithmetic averages?). Ambos marcadores moleculares revelaron claramente la relación filogenética entre genotipos. La caracterización morfológica permitió diferenciar correctamente las variedades analizadas, revelando únicamente la semejanza externa entre los genotipos. La caracterización completa permitió diferenciar inequívocamente los cultivares recientemente liberados para registrarlos y proteger los derechos de los mejoradores.
Effect of processed aloe vera gel on immunogenicity in inactivated quadrivalent influenza vaccine and upper respiratory tract infection in healthy adults: A randomized double-blind placebo-controlled trial (2021)

Oral intake of PAG did not show a significant increase in seroprotection rate from an immunogenicity perspective. However, it reduced the number of URI episodes. A well-designed further study is needed on the effect of PAG's antibody response against A/H3N2 in the future.
