Acute plasma volume expansion alters cardiovascular but not thermal function during moderate intensity prolonged exercise (2000)

To investigate the hypothesis that the increase in plasma volume (PV) that typically occurs with training results in improved cardiovascular and thermal regulation during prolonged exercise, eight untrained males (V(O2)peak = 3.52 +/- 0.12 L x min(-1)) performed 90 min of cycle ergometry at 62% V(O2)peak before and after acute PV expansion. Subjects were infused with a PV-expanding solution (dextran (6%) or Pentaspan (10%)) equivalent to 6.7 mL x kg(-1) body mass (PVX) or acted as their own control (CON) in a randomized order. PVX resulted in a calculated 15.8% increase in resting PV, which relative to CON, was maintained throughout the exercise (P < 0.05). During PVX, heart rate was lower (P < 0.05) and stroke volume and cardiac output were higher (P < 0.05) during the exercise. Mean arterial pressure and total peripheral resistance, although altered by exercise (P < 0.05), were not different between the two conditions. Core temperature, which was progressively increased by the exercise (P < 0.01), was not affected by PVX. A similar decrease in body weight was observed between the conditions as a result of the exercise (P < 0.01). These results indicate that acute PVX alters cardiovascular performance without affecting the thermoregulatory response to prolonged cycle exercise.

Simple poly(dimethylsiloxane) surface modification to control cell adhesion (2008)

Abstract Poly(dimethylsiloxane) (PDMS) has a long history of exploitation in a variety of biological and medical applications. Particularly in the past decade, PDMS has attracted interest as a material for the fabrication of microfluidic biochip. The control of cell adhesion on a PDMS surface is important in many microfluidic applications such as cell culture or cell‐based chemicals/drug testing. Unlike many complicated approaches, this study reports simple methods of PDMS surface modification to effectively inhibit or conversely enhance cell adhesion on a PDMS surface using Pluronic surfactant solution and poly‐ L ‐lysine, respectively. This research basically succeeded our prior work to further confirm the long‐term capability of 3% Pluronic F68 surfactant to suppress cell adhesion on a PDMS surface over a 6‐day cell culture. Microscopic observation showed that the treated PDMS surface created an unfavorable interface, where chondrocytes seemed to clump together on day 2 and 6 after chondrocyte seeding, and there was no sign of chondrocyte spreading. On the opposite side, results demonstrated that the poly‐ L ‐lysine‐treated surface significantly increased fibroblast adhesion by 32% in contrast to the untreated PDMS, which is comparable to the commercial cell‐culture‐grade microplate. However, fibronectin treatment did not have such an effect. All these fundamental information is found useful for any PDMS‐related application. Copyright © 2008 John Wiley & Sons, Ltd.
The magnetic gradient tensor: Its properties and uses in source characterization (2006)

Airborne magnetic surveys have improved dramatically over the past three decades with advances in both data acquisition and image processing techniques. Magnetic surveys form an integral part of exploration programs and are now routinely undertaken before geological mapping programs. These advances have been made despite treating the magnetic field as a scalar, wherein various processing procedures that assume a potential field are compromised. If the vector information could be retrieved, either by direct measurement or by mathematical manipulation, magnetic surveys could be improved even further. For instance, the total magnetic intensity (TMI) could be corrected so it represents a true potential field.
Electron emission by nanosecond switching in PLZT (1992)

Copious electron emission from a PLZT ceramic surface takes place either when the surface is illuminated with laser pulses, or when short high-voltage pulses are applied. In the latter case, charge densities of up to 5 μC/cm2 and current densities of some ten of amperes per square centimetre have been measured. Depending on the position of the material in its phase diagram, different behaviour of the emission has been observed. Consequently the pulsed electron beam varies with respect to its pulse length, its amplitude, and its risetime. Further investigation of these data related to the corresponding material state might be a good diagnostic method, interesting for the switching dynamics in the ns-region. Moreover, a direct application as a pulsed “Ferroelectric Electron Beam Source” is envisaged, as the emission does not rely on vacuum, but also works in low pressure gas or plasma. A maximum repetition frequency of 2 MHz has been established. An improvement of all data of the emitted electron beam seems feasible.
Bonding of Hg(II) to Reduced Organic Sulfur in Humic Acid As Affected by S/Hg Ratio (2001)

Organic matter is an important sorbent of heavy metals in soils and sediments. The heterogeneity of organic matter, including the presence of various reactive O-, N-, and S-bearing ligands, makes it difficult to precisely characterize the nature of metal-ligand binding sites. The objective of this research was to characterize the extent and nature of Hg(II) bonding with reduced organic S in soil organic matter. Sulfur-rich humic acid (0.7 +/- 0.1 mol of S kg-1) was extracted from samples of surface soil from a marine wetland. Synchrotron X-ray absorption near-edge structure (XANES) analysis at the S K edge indicated that 70 +/- 3 mol % of the organic S was in a reduced oxidation state. Aqueous solutions containing 2 mmol of Hg kg-1, 0.1 M NaNO3, and humic acid added at various S/Hg molar ratios at pH 5.60 +/- 0.02 were characterized using extended X-ray absorption fine structure (EXAFS) spectroscopy at the Hg LIII edge. Spectral fitting showed that as the total S/Hg ratio increased from 0.6 to 5.6 (reduced S/Hg of 0.4-4.0), the fraction of Hg-S bonding relative to Hg-O (or Hg-N) bonding increased from 0.4 to 0.9. Results demonstrated preferential bonding of Hg(II) to reduced organic S sites and indicated that multiple sulfur ligands were coordinated with Hg2+ ions at high S/Hg ratios, which corresponded to low levels of complexed Hg(II).
The Effect of Clinical Skills Training on Medical Students Clinical Competencies in the Management of Vaginal Delivery (2005)

Introduction. Clinical skills training program provides an opportunity for medical students to improve their clinical skills in a simulated setting which is designed and equipped for learning a number of key skills by practicing on manikins and related equipments. The aim of this study was to determine the effect of clinical skills training program on clinical competencies of medical students in the management of vaginal delivery in Tabriz Medical University. Methods. In this quasi-experimental research with one group, pre- and post-test design, 50 medical students were selected randomly and assessed using a valid and reliable questionnaire asking about their clinical competencies in the management of different stages of vaginal delivery and also about their suturing skill. Likert scale was used for determining the level of competency based on self-assessment approach. Data analysis was done by SPSS software using descriptive analysis, paired t-test, ANOVA and Pearson correlation coefficient. Results. A significant increase was observed in the mean score of skills related to pre-delivery stage (from 14±13.65 to 89±10.72), skills needed during performing the delivery (from 18.17±13.3 to 88.95±9.26), and skills needed during the post-delivery stage such as suturing and dressing (from 31.07±16.57 to 85.17±12.78). There was a significant difference between the mean score related to the skills needed before, during and after delivery, before and after education. Conclusion. Practicing in Clinical Skills Center considerably increased perceived self-efficacy of medical students for doing the skills needed for the management of a safe vaginal delivery which in turn could lead to increasing their skills in confronting patients.

A Hierarchical Hybrid Optical-Electronic Network-on-Chip (2010)

Network-on-chip (NoC) can improve the performance, power efficiency, and scalability of multiprocessor system-on-chip (MPSoC). However, traditional NoCs using metallic interconnects consume significant amount of power to deliver even higher communication bandwidth required in the near future. Optical NoCs are based on CMOS-compatible optical waveguides and micro resonators, and promise significant bandwidth and power advantages. In this paper, we propose a hybrid optical mesh NoC, HOME, which utilizes optical waveguides as well as metallic interconnects in a hierarchical manner. HOME employs a new set of protocols to improve the network throughput and latency. We compared HOME with a matched optical mesh NoC for a 64-core MPSoC in 45nm, using SPICE simulations and our cycle-accurate multi-objective NoC simulation platform, MoLab. Comparing with the optical mesh NoC, HOME uses 75% less optical/electronic interfaces and laser diodes. Simulation results show that HOME achieves 17% higher throughput and 40% less latency while consuming 42% less power.

Molecular cloning of three distinct forms of the Na+,K+-ATPase .alpha.-subunit from rat brain (1986)

Rat brain and kidney cDNA libraries were constructed and screened with a cDNA insert corresponding to the mRNA for the sheep kidney Na+,K+-ATPase catalytic subunit. The alpha-subunit cDNAs isolated from the kidney library were derived from a single class of messenger RNA, and the brain cDNAs were derived from three classes of messenger RNA. The most abundant brain cDNA, which spans 5.1 kilobases, encodes the alpha(+) form of the enzyme. The second most abundant brain cDNA, which spans 3.65 kilobases, is identical with that of the kidney form and therefore encodes the alpha isoform. The third class of cDNA, which spans 3.55 kilobases, was present at low abundance and encodes an isoform of the alpha-subunit, designated alpha III, which has not been identified previously. The complete nucleotide sequence and deduced amino acid sequence for each of the brain and kidney cDNAs have been determined. In addition, we have identified a lysine-rich sequence that may function as a movable, ion-selective gate during cation binding and occlusion and have also identified several amino acid sequence variations that appear to explain some of the well-known species and tissue differences in cardiac glycoside sensitivity.
Injectable collagen in laryngeal rehabilitation (1984)

Glottic insufficiency has been successfully managed by Teflon augmentation of paretic vocal cords over the past two decades. Collagen fulfills the criteria for a suitable bioimplant and is an attractive alternative as it is a normal constituent of the extracellular protein matrix. This study explores the use of modified bovine collagen injected into the canine larynx. Clinical situations are simulated by creating lesions and injecting collagen at different sites. The technique permits precise placement and quantification. Histologic study of the collagen implant fails to show evidence of significant foreign body reaction. The injected collagen appears similar to viable connective tissue and is colonized by host fibroblasts and nourishing capillaries.
SAA: A guide to implementing IBM's Systems Application Architecture (1991)

Introduction The use of polymeric clips in securing the appendiceal stump has been increasingly reported as a viable alternative to current methods in emergency laparoscopic appendicectomy. We evaluated the operative outcomes following the use of polymeric clips versus endoscopic ligatures. The primary endpoint was operative time, with secondary outcomes including complications, inpatient stay, and cost analysis. Materials and methods Operative records were retrospectively analysed to identify patients undergoing laparoscopic appendicectomy between January 2014 and June 2015. Data collected included age, gender, body mass index, duration of surgery, length of hospital stay, antibiotic use, preoperative haematological and biochemical parameters, 30-day readmission rate and complications. Results A total of 125 patients were included within the study, with 78 within the endoloop group and 47 in the polymeric clip group. There were no differences in age, gender, body mass index, hospital stay, antibiotic use, 30-day readmission rates or postoperative complications. Operative time was significantly reduced in the polymeric clip group (59 vs. 68 minutes, P = 0.00751). The use of polymeric clips cost £21 compared with £49 for endoloops per operation, which rose to £70 if both clips and endoloops were used during the procedure. Discussion Polymeric clips are a safe, viable and economical method for securing the appendiceal stump during laparoscopic appendicectomy. The clinical significance of nine minutes of reduced operating time in the polymeric clip cohort warrants further study with an adequately powered randomised controlled trial.
Interpretations (1979)

Without moralising, we may profitably study history to select those parts we should like to see repeated. Surely the phenomenal burst of fruitful innovation we have just recounted represents the sort of thing that scientists, research directors and business managers would like to think could be induced to occur again in similar or different fields. Judging by the recent literature on the subject, a great deal of thought and effort is being expended to find and nurture the seeds of creativity and innovation.KeywordsNatural RubberChain StraightenerCobalt CatalystIsotactic PolypropyleneResearch DirectorThese keywords were added by machine and not by the authors.

Selective interactions between different species of mycorrhizal fungi and <i>Rhizobium meliloti</i> strains, and their effects on growth, N<sub>2</sub>‐fixation (<sup>15</sup>N) and nutrition of <i>Medicago sativa</i> L. (1991)

Three isolates of vesicular-arbuscular (VA) mycorrhizal fungi, belonging to the species Glomus mosseae (Nicol. and Gerd.) Gerd. and Trappe, G. fasciculatum (Taxter sensu Gerd.) Gerd, and Trappe, and G. caledonium (Nicol. and Gerd.) Trappe and Gerd, were inoculated in dual combinations with six strains of Rhizobium meliloti with the aim of testing these combinations for functional compatibility with their common host plant, the legume Medicago sativa L. Symbiotic efficiency (promotion of plant growth and N and P nutrition) was found to be dependent on the particular combination of Rhizobium strain and Glomus species indicating selective and specific compatibilities between strains and isolates of the two types of microsymbiont, but also between them and the common host plant. Observed effects on plant growth were in general, though not always, related to the extent of VA mycorrhizal colonization. Although the different mycorrhizal and/or rhizobial treatments produced different effects on plant growth, the rate of nodule formation on M. sativa roots remained constant. Most mycorrhizal treatments increased the concentration and/or content of N in plant shoots but effectiveness was in the order: G. fasciculatum > G. mosseae > G. caledonium. In some cases, this increase in N-content may be a consequence of a P-mediated stimulation of N<sub>2</sub> -fixation by VA mycorrhiza, as ascertained using <sup>15</sup> N. In other instances, however, the increase seems to reflect a VA mycorrhizal-mediated enhancement of N-uptake from soil. VA mycorrhizal inoculation decreased the concentration of Ca and Mg in plant shoots and a buffering effect of VA mycorrhiza in situations of nutrient excess in soil is proposed.
Long‐term survival estimates for imatinib versus interferon‐α plus low‐dose cytarabine for patients with newly diagnosed chronic‐phase chronic myeloid leukemia (2004)

Assuming the relation between CCyR and survival with interferon-alpha holds for imatinib, higher CCyR rates with imatinib therapy will result in an estimated 6.23 life-years gained compared with treatment with IFN+LDAC.
Lipid Coated Microbubbles and Low Intensity Pulsed Ultrasound Enhance Chondrogenesis of Human Mesenchymal Stem Cells in 3D Printed Scaffolds (2016)

Lipid-coated microbubbles are used to enhance ultrasound imaging and drug delivery. Here we apply these microbubbles along with low intensity pulsed ultrasound (LIPUS) for the first time to enhance proliferation and chondrogenic differentiation of human mesenchymal stem cells (hMSCs) in a 3D printed poly-(ethylene glycol)-diacrylate (PEG-DA) hydrogel scaffold. The hMSC proliferation increased up to 40% after 5 days of culture in the presence of 0.5% (v/v) microbubbles and LIPUS in contrast to 18% with LIPUS alone. We systematically varied the acoustic excitation parameters-excitation intensity, frequency and duty cycle-to find 30 mW/cm<sup>2</sup>, 1.5 MHz and 20% duty cycle to be optimal for hMSC proliferation. A 3-week chondrogenic differentiation results demonstrated that combining LIPUS with microbubbles enhanced glycosaminoglycan (GAG) production by 17% (5% with LIPUS alone), and type II collagen production by 78% (44% by LIPUS alone). Therefore, integrating LIPUS and microbubbles appears to be a promising strategy for enhanced hMSC growth and chondrogenic differentiation, which are critical components for cartilage regeneration. The results offer possibilities of novel applications of microbubbles, already clinically approved for contrast enhanced ultrasound imaging, in tissue engineering.
A fast spatial constrained fuzzy kernel clustering algorithm for MRI brain image segmentation (2007)

A fast kernel clustering algorithm incorporating spatial constraints is proposed for segmenting MRI (magnetic resonance imaging) brain images. The algorithm called FKFCM (fast kernel based fuzzy c-means clustering) is implemented by using a kernel technique, which can improve the separability of clustered data, for segmenting MRI images. The kernel technique implicitly maps input data to a higher dimensional kernel space and therefore transforms a nonlinear segmenting problem to a linear one. Because the clustering performed in a kernel space is generally computational consuming, a fast clustering scheme is implemented to speed up the computation. Experimental results on synthetic image, digital phantom and real clinical data indicate the proposed algorithm is effective for segmenting MRI images corrupted by noise and intensity inhomogeneity, and usually outperforms the corresponding conventional methods.
Child Complainants and the Court Process in Australia (2009)

In recent years, it has been recognised that child complainants in the criminal justice system can experience difficulties over and above those of other complainants and that children can experience the court process as extremely traumatising. This can be exacerbated if children are complainants in child sexual offence matters and if they have to give evidence against a family member. This paper has three primary aims. First, it outlines the major factors that contribute to making court processes harrowing for child complainants. Second, it outlines some of the main initiatives that have been introduced to address these factors. Finally, it weighs up the evidence about initiatives designed to assist child complainants and concludes that such initiatives have had only limited practical impact for child complainants in the criminal justice system. The limited impact is attributed to the need to balance the rights of the accused with consideration for the complainant, a failure to translate legislative changes into practice, the impact of judicial discretion and/or a focus on protecting child complainants at the expense of increasing convictions.
