Formative feedback on a patient-based assessment: comparing student perceptions of two feedback methods (2011)

Introduction: Although formative feedback is widely recognized as an essential aid to student learning, there is little evidence regarding effective ways of providing formative feedback on structured clinical exams. This study compares students’ perceptions of immediate, face-to-face feedback with delayed, written on-line faculty feedback on their Obstetrics and Gynecology medical student clerkship patient-based assessment (PBA) at the University of Iowa. Methods: 163 third year medical students performed the PBA between October 2009-10. Students were assigned to immediate face-to-face or delayed, written on-line feedback. Students were then invited to participate in an anonymous web-based survey. Independent samples t-tests were used to determine whether the mean differences between the groups in ratings of commonly accepted characteristics of effective feedback were statistically significant. Results: 97 students responded to the survey. Of the 84 who responded to the questions about feedback quality (face-to-face feedback n=40, web-based feedback n=44), face-to-face feedback generally scored higher than web-based feedback, and received significantly higher ratings in 9 of 11 variables measured (p ≤ 0.05). Qualitative comments indicated preference for two-way interaction with evaluators. Conclusion: Students rate immediate face-to-face feedback more beneficial than delayed, web-based written feedback on a patient-based assessment.
The effect of traumatic brain injury on sustained attention and working memory (2011)

This study provides further evidence of WM deficits following TBI as well as possible SA deficits in some individuals. The results also suggest that WM and SA are inter-related processes. Future studies are needed to replicate the results with larger sample sizes. Based on these findings, patients with TBI may present with WM and SA deficits.
Strategies for hybrid techniques of UV lithography and thermal nanoimprint (2008)

This paper discusses a hybrid process of thermal nanoimprint and UV lithography, carried out within UV curable SU-8 and mr-L 6000.5, respectively, on the basis of experiments and calculations of the light intensity distribution within the photoresist. For the non-transparent Si stamps with mixed pattern sizes, ranging from approx. 100nm to 150μm, the experiments revealed an optimum imprint temperature of 80°C for SU-8 and 70°C to 100°C for mr-L 6000.5. UV stabilization of the imprinted patterns after stamp removal is possible with negligible loss of the patterns when a broadband UV exposure is applied and the post exposure bake is performed as a temperature ramp, starting in the range of the glass transition temperature of the photoresists. UV stabilized patterns of mr-L 6000.5 can be replicated themselves (working-stamp), after applying a conventional anti-adhesive coating. A successful hybrid lithography of thermal nanoimprint lithography and UV lithography depends on the exposure conditions as well as on the layout of the stamp patterns with respect to the photomask pattern. Superimposing the patterns of a photomask is only uncritical for imprinted patterns in the range of the exposure wavelength and larger, where a trench may develop underneath the edges of imprinted patterns of ≥1μm width. This is due to a shadowing effect caused by exposure over topography. A sufficient stabilization of smaller imprinted patterns in the range of 100nm within a hybrid lithography approach is only feasible when the photomask patterns are not in direct vicinity of the pre-patterned photoresist.
WEARABLE TECHNOLOGIES FOR EMOTION COMMUNICATION (2008)

This paper discusses the possibilities of exploring new ways of expressing emotions with wearable technologies. In the paper, the terms ‘wearable technologies’ and ‘wearables’ are used to refer to garments and accessories that have embedded smart technologies with the ability to connect to an electronic network and the ability to create customisable, dynamic and interactive responses.

Characteristics and risk factors of hypoglycemia in hospitalized diabetic patients monitored with bedside blood glucose management system (2013)

Objective
To investigate the characteristics and related risk factors of hypoglycemia in hospitalized diabetic patients.


Methods
Retrospectively analyze the characteristics and related risk factors of hypoglycemia in 3634 diabetic patients hospitalized from January 2008 to December 2011 according to the 203 802 blood glucose monitoring data. The blood glucose was monitored with SureStep Flexx bedside blood glucose management system. Comparison of rates among groups was carried out with contingency table analysis.


Results
Total of 3634 patients (male/female: 1805/1829) were enrolled in this study with a mean age of (59±15) yrs. During the study period, the blood glucose were monitored for 203 802 times in these patients, and was monitored more frequently before breakfast (33 567/203 802, 16.5%), and monitored less in early morning and before lunch (17 701/203 802, 8.7% and 21 271/203 802, 10.4%). Hypoglycemia episodes occurred for 2453 times in the patients and the occurrence of hypoglycemia was 1.2% (2453/203 802), and occurred more frequently in early morning and before lunch (506/2453, 20.6% and 406/2453, 16.5%). About one third (1127/3634, 31.0%) of the patients experienced hypoglycemia, of which with one episode of hypoglycemia occurred in 590 cases (52.4%), 2-3 episodes in 370 cases (32.8%) and more than four episodes in 167 patients (14.8%). With the binary logistic regression analysis , type 1 diabetes mellitus(T1DM)(OR: 2.478, 95%CI: 1.067-5.754), repeated insulin therapy(insulin pump therapy: 2.254(1.283-3.959), more than 3 times insulin therapy daily: 2.307(1.310-4.065), pre-mixed insulin therapy: 2.119(1.179-3.808) )and glycated hemoglobin A1c(HbA1c) <7.0%(2.008(1.560-2.583) ) were the main risk factors of hypoglycemia in hospitalized diabetics.


Conclusion
For hospitalized diabetics, hypoglycemia happens more frequently in early morning and before lunch, but the blood glucose is monitored less in these two periods of time. The blood glucose should be paid more attention to in patients with T1DM or repeated insulin therapy or a HbA1c>7.0% to prevent hypoglycemia.

TNF RECEPTOR 2, NOT TNF RECEPTOR 1, ENHANCES MESENCHYMAL STEM CELL-MEDIATED CARDIAC PROTECTION FOLLOWING ACUTE ISCHEMIA (2010)

Mesenchymal stem cells (MSCs) may improve myocardial function after I/R injury via paracrine effects, including the release of growth factors. Genetic modification of MSCs is an appealing method to enhance MSC paracrine action. Ablation of TNF receptor 1 (TNFR1), but not TNFR2, increases MSC growth factor production. In this study, therefore, we hypothesized that 1) preischemic infusion of MSCs derived from TNFR1 knockout (TNFR1KO) mice will further improve myocardial functional recovery and that 2) TNFR2KO and TNFR1/2KO will abolish MSC-mediated protection in the heart after I/R injury. Mesenchymal stem cells were harvested from adult C57BL/6J (wild-type 1 [WT1]), B6129SF2 (WT2), TNFR1KO, TNFR2KO, and TNFR1/2KO mice. Mesenchymal stem cells were cultured and adopted for experiments after passage 3. Isolated hearts from adult male Sprague-Dawley rats were subjected to 25 min of ischemia and 40 min of reperfusion (Langendorff model), during which time myocardial function was continuously monitored. Before ischemia, 1 mL of vehicle or 1 x 10(6) MSCs/mL from WT1, WT2, TNFR1KO, TNFR2KO, or TNFR1/2KO was infused into the hearts (n = 4-6 per group). Treatment of C57BL/6J mice with MSC before ischemia significantly increased cardiac function. TNFR1 knockout MSCs demonstrated greater cardioprotection when compared with WT MSCs after I/R, as exhibited by improved left ventricular developed pressure and +/-dp/dt. However, infusion of MSCs from TNFR2KO and TNFR1/2KO mice either offered no benefit or decreased MSC-mediated cardiac functional recovery in response to I/R when compared with WT MSCs. TNFR1 signaling may damage MSC paracrine effects and decrease MSC-mediated cardioprotection, whereas TNFR2 likely mediates beneficial effects in MSCs.

A High-Frequency Phase-Compensation Fractional–N Frequency Synthesizer (2005)

A new type of high-frequency fractional-N frequency divider with a phase compensation technique is developed, which can operate for frequencies ranging from 1 GHz to 2.5 GHz, and achieve a divide ratio of (256-271) + (f/16). The on-chip phase compensation by a delay-locked loop (DLL) is adopted to reduce the fractional spurs in the fractional-N frequency synthesizer. The fractional-N synthesizer is simulated using a 0.35- /spl mu/m standard CMOS technology and the power dissipation is about 70 mW under the supply voltage of 3.3 V.

Literacy, assistive technology and e‐inclusion (2007)

This article considers research directed at conceptualising aspects of assistive technology of benefit to ineffective readers. In particular, it deals with educational practice that fosters e‐inclusion. Exploring the potential of digital technologies, this article presents results from research in a five‐year period in Denmark. Frequent and proper use of assistive technologies may promote reading fluency, but the core objective is to overcome barriers to learning and to support ineffective readers to work at age‐related expectations. Compared to learning without any assistive technology, ineffective readers develop higher intrinsic motivation and self‐esteem regarding school work. The use of digital technology helps them when translating written words into spoken words (decoding) and when getting meaning from the text. In general, they also become more self‐reliant and produce texts of higher quality. An innovative strategy, consequently, encompasses quality reading education and implementation of technology enabling age‐relevant text comprehension.
Heat Shock Inhibits Cytokine-Induced Nitric Oxide Synthase Expression by Rat and Human Islets (1998)

In this study the effects of heat shock on interleukin-1 (IL-1)induced inhibition of islet metabolic function were examined. Treatment of rat islets for 18 h with IL-1 results in a potent inhibition of glucose-stimulated insulin secretion. The inhibitory effects of IL-1 on insulin secretion are completely prevented if islets are pretreated for 60 min at 42 C before cytokine stimulation. Heat shock also prevents IL-1-induced inhibition of insulinoma RINm5F cell mitochondrial aconitase activity. The protective effects of heat shock on islet metabolic function are associated with the inhibition of IL-1-stimulated inducible nitric oxide synthase (iNOS or NOS II) expression. Islets heat shocked for 60 min at 42 C fail to express iNOS (messenger RNA or protein) or produce nitrite in response to IL-1. IL-1-induced iNOS expression by rat islets requires activation of the transcriptional regulator nuclear factor B (NF-B). Heat shock prevents IL-1-induced NF-B nuclear localization by inhibiting inhibitory protein B (IB) degradation in rat islets. Similar to rat islets, heat shock (stimulated by 90 min incubation at 42 C) prevents IL-1 interferon -induced iNOS expression and NF-B nuclear localization in human islets. IL-1 also stimulates heat-shock protein 70 (hsp 70) expression by rat islets, and hsp 70 expression is dependent on islet production of nitric oxide. Last, evidence is presented that implicates nitric oxide as a stimulus for the expression of proteins that participate in islet recovery from nitric oxide-mediated damage. These studies indicate that heat shock prevents cytokine-induced islet damage by inhibiting iNOS expression, and suggest that nitric oxide is one effector molecule that stimulates the expression of factors involved in -cell recovery from nitric oxide-mediated damage.
Liposomal photosensitizers: potential platforms for anticancer photodynamic therapy (2011)

Photodynamic therapy is a well-established and clinically approved treatment for several types of cancer. Antineoplastic photodynamic therapy is based on photosensitizers, i.e., drugs that absorb photons translating light energy into a chemical potential that damages tumor tissues. Despite the encouraging clinical results with the approved photosensitizers available today, the prolonged skin phototoxicity, poor selectivity for diseased tissues, hydrophobic nature, and extended retention in the host organism shown by these drugs have stimulated researchers to develop new formulations for photodynamic therapy. In this context, due to their amphiphilic characteristic (compatibility with both hydrophobic and hydrophilic substances), liposomes have proven to be suitable carriers for photosensitizers, improving the photophysical properties of the photosensitizers. Moreover, as nanostructured drug delivery systems, liposomes improve the efficiency and safety of antineoplastic photodynamic therapy, mainly by the classical phenomenon of extended permeation and retention. Therefore, the association of photosensitizers with liposomes has been extensively studied. In this review, both current knowledge and future perspectives on liposomal carriers for antineoplastic photodynamic therapy are critically discussed.
Effortless Data Exploration with zenvisage: An Expressive and Interactive Visual Analytics System (2016)

Data visualization is by far the most commonly used mechanism to explore data, especially by novice data analysts and data scientists. And yet, current visual analytics tools are rather limited in their ability to guide data scientists to interesting or desired visualizations: the process of visual data exploration remains cumbersome and time-consuming. We propose zenvisage, a platform for effortlessly visualizing interesting patterns, trends, or insights from large datasets. We describe zenvisage's general purpose visual query language, ZQL ("zee-quel") for specifying the desired visual trend, pattern, or insight - ZQL draws from use-cases in a variety of domains, including biology, mechanical engineering, climate science, and commerce. We formalize the expressiveness of ZQL via a visual exploration algebra, and demonstrate that ZQL is at least as expressive as that algebra. While analysts are free to use ZQL directly, we also expose ZQL via a visual specification interface that we describe in this paper. We then describe our architecture and optimizations, preliminary experiments in supporting and optimizing for ZQL queries in our initial zenvisage prototype, and a user study to evaluate whether data scientists are able to effectively use zenvisage for real applications.
The generation of truly random binary numbers (1970)

The generation of independent random binary digits with an extremely small difference between the probabilities for 0 and 1 is discussed and shown to be practicable by means of a scale-of-2 counter counting randomly timed input pulses for a fixed time interval. It is shown that such digits can be used to form other random numbers with appreciable advantages of speed and accuracy, in comparison with the direct generation of similar numbers by means of a scale-of-n counter, where n>4. The use of ternary digits, generated with a scale-of-3 counter, would give a slight further theoretical advantage, but would be less convenient to implement than binary.
Biocompatibility of Bacterial Cellulose Based Biomaterials (2012)

Some bacteria can synthesize cellulose when they are cultivated under adequate conditions. These bacteria produce a mat of cellulose on the top of the culture medium, which is formed by a three-dimensional coherent network of pure cellulose nanofibers. Bacterial cellulose (BC) has been widely used in different fields, such as the paper industry, electronics and tissue engineering due to its remarkable mechanical properties, conformability and porosity. Nanocomposites based on BC have received much attention, because of the possibility of combining the good properties of BC with other materials for specific applications. BC nanocomposites can be processed either in a static or an agitated medium. The fabrication of BC nanocomposites in static media can be carried out while keeping the original mat structure obtained after the synthesis to form the final nanocomposite or by altering the culture media with other components. The present article reviews the issue of biocompatibility of BC and BC nanocomposites. Biomedical aspects, such as surface modification for improving cell adhesion, in vitro and in vivo studies are given along with details concerning the physics of network formation and the changes that occur in the cellulose networks due to the presence of a second phase. The relevance of biocompatibility studies for the development of BC-based materials in bone, skin and cardiovascular tissue engineering is also discussed.
Assessing Positivity and Circulating Levels of NS1 in Samples from a 2012 Dengue Outbreak in Rio de Janeiro, Brazil (2014)

Dengue virus (DENV) represents a major threat to public health worldwide. Early DENV diagnosis should not only detect the infection but also identify patients with a higher likelihood to develop severe cases. Previous studies have suggested the potential for NS1 to serve as a viral marker for dengue severity. However, further studies using different sera panels are required to confirm this hypothesis. In this context, we developed a lab-based ELISA to detect and quantitate NS1 protein from the four DENV serotypes and from primary and secondary cases. This approach was used to calculate the circulating NS1 concentration in positive samples. We also tested the NS1 positivity of DENV-positive samples according to the Platelia Dengue NS1 Ag assay. A total of 128 samples were positive for DENV infection and were classified according to the WHO guidelines. The overall NS1 positivity was 68% according to the Platelia assay, whereas all samples were NS1-positive when analyzed with our lab-based ELISA. Fifty-four samples were positive by PCR, revealing a co-circulation of DENV1 and DENV4, and the NS1 positivity for DENV4 samples was lower than that for DENV1. The circulating NS1 concentration ranged from 7 to 284 ng/mL. Our results support previous data indicating the low efficiency of the Platelia assay to detect DENV4 infection. Moreover, this work is the first to analyze NS1 antigenemia using retrospective samples from a Brazilian outbreak.
