Effect of Saliva Contamination on the Microshear Bond Strength of One-step Self-etching Adhesive Systems to Dentin (2006)

This study evaluated the effect of saliva contamination and decontamination methods on the dentin bond strength of one-step self-etching adhesive systems. Three commercially available "all-in-one" adhesives (One Up Bond F, Xeno III and Adper Prompt) and one resin composite (Filtek Z-250) were used. Third molars stored in distilled water with 0.5% thymol at 4 degrees C were ground with #600 SiC paper under running water to produce a standardized smear layer. The specimens were randomly divided into groups according to contamination methods: no contamination, which was the control (C); contamination of the adhesive surface with fresh saliva before light curing (A) and contamination of the adhesive surface with fresh saliva after light curing (B). Each contamination group was further subdivided into three subgroups according to the decontamination method: A1-Saliva was removed by a gentle air blast and the adhesive was light-cured; A2-Saliva was rinsed for 10 seconds, gently air-dried and the was adhesive light-cured; A3-Saliva was rinsed and dried as in A2, then the adhesive was re-applied to the dentin surface and light-cured; B1-Saliva was removed with a gentle air blast; B2-Saliva was rinsed and dried; B3-Saliva was rinsed, dried and the adhesive was re-applied and light cured. Tygon tubes filled with resin composite were placed on each surface and light cured. All specimens were stored in distilled water at 37 degrees C for 24 hours. Microshear bond strength was measured using a universal testing machine (EZ test), and data were analyzed by one-way ANOVA followed by the Duncan test to make comparisons among the groups (p<0.05). After debonding, five specimens were selected and examined in a scanning electron microscope to evaluate the modes of fracture. The A2 subgroup resulted in the lowest bond strength. For One Up Bond F and Adper Prompt, there was no significant difference between subgroup A1 and the control, and subgroup A3 and the control (p>0.05). Bond strengths of all B groups were significantly lower compared to the controls (p<0.05). For Xeno III, A1 subgroup showed the greatest decrease in bond strength as compared to the control (p<0.05). On the other hand, it showed more resistance to salivary contamination after adhesive curing. There was no statistically significant difference among the control groups (p>0.05).
Contactless Confined Readout of Quartz Crystal Resonator Sensors (2006)

A configuration and method for contactless readout of the resonance response of a thickness-shear mode quartz resonator sensor is presented. The configuration uses a crystal with a large common electrode on the front face, and one, or more, small electrodes on the back face, leading to localized sensing regions. Each back electrode is capacitively coupled to a separated tip electrode. The tip consists of a small disc and a guard ring, which confine the electric field to the electrode area and make the measurement unaffected by the stray parallel capacitances. Analysis shows that the proposed configuration can be modeled as an extension of the Butterworth-Van Dyke (BVD) circuit and that, by a proper choice of the reference frequency around resonance, it is possible to obtain frequency readings that do not depend on the tip-to-crystal stand-off distance. Experimental results show that a mass load added on the front electrode can be consistently detected and measured irrespective of the tip-to-crystal stand-off distance.
Tenofovir, Lamivudine, and Dolutegravir Among Rural Adolescents in Zimbabwe: A Cautionary Tale (2022)

Tenofovir disoproxil fumarate, lamivudine, and dolutegravir (TLD) as a safe and more effective single daily dose regimen is rolling out in Africa for people living with HIV. Although access to viral load (VL) testing is improving, patients may still be transitioned to TLD with virological failure and potential drug resistance. We reviewed annual VL test results of 390 children and adolescents who had enrolled in a community-based antiretroviral therapy program in rural Zimbabwe between 2018 and 2019. VL testing was done by the near point of care simplified amplification-based assays (Diagnostics for the Real World, Sunnyvale, CA, USA) at Chidamoyo Christian Hospital and rate of virological suppression (VS) on TLD (VL <1,000 copies/mL) was assessed. Overall, 184 children and adolescents on TLD were enrolled in this study. The median [interquartile range (IQR)] age was 15 (11-19) years, above half of the participants were female (57%). Before switching to TLD, rate of VS was 76% (139/184). After a median (IQR) duration of 6.9 (5.5-9.1) months on TLD, VS was observed in 95% (174/184) of the participants. Of the 10 participants with VL ≥1,000 copies/mL on TLD, 90% (9/10) were failing on their previous regimens, 6 of 9 (67%) having been on boosted protease inhibitor-based regimens. A high rate (95%) of VS was observed among children and adolescents on TLD in rural Zimbabwe. TLD may address the problems of virological failure and emergence of resistance in Africa. However, longer follow-up might be needed to ascertain sustained VS in this vulnerable population. Randomized Control Trial NCT03986099.
Research Radar Analyses of the Internal Boundary Layer over Cape Canaveral, Florida, during the Landfall of Hurricane Frances (2004) (2012)

Abstract The structure of the coastal internal boundary layer (IBL) during a landfalling hurricane has important ramifications on operational forecasting, structural design, and poststorm damage assessment. Despite these important issues, the mean IBL structure at the coastline during landfall is poorly understood. Knowledge of the vertical kinematic structure within tropical cyclones over water has improved greatly through aircraft reconnaissance missions and the advent of GPS dropsondes and stepped frequency microwave radiometers. Unfortunately, reconnaissance and research aircraft are limited to overwater missions, resulting in a poor understanding of vertical kinematic structure near the coastal interface, where changes in IBL structure are expected due to changes in surface roughness. Composite single- and dual-Doppler radar observations collected by the Shared Mobile Atmospheric Research and Teaching Radars during the landfall of Hurricane Frances (2004) are presented. Data analyses from the Cape Canaveral, Florida, region reveal a pronounced IBL throughout the data collection period. As a result, significant variability in the analyzed wind speed and direction are found across and near the coastal interface. IBL height is found to be suppressed when compared to an accepted empirical growth model, while multiple abrupt roughness transitions associated with the Cape Canaveral region contribute to a complex mean IBL structure.

Wireless Sensor and Actor Networks: Localized Movement Control Algorithms for Maintaining Coverage and Connectivity (2011)

Wireless Sensor and Actor Networks (WSANs) are gaining growing interest because of their suitability for mission-critical applications that require autonomous and intelligent interaction with the environment. Hazardous application environments make actors susceptible to physical damage. Failure of a critical (i.e. cut-vertex) actor partitions the inter-actor network into disjointed segments while leaving a coverage hole. Maintaining inter-actor connectivity and coverage is extremely crucial in most applications of WSANs where actors have to quickly plan an optimal coordinated response to detected events. This book presents a series of localized novel algorithms that pursue controlled movement of existing (internal) actors to restore the lost connectivity while minimizing the impact on coverage. The performance of proposed approaches is analyzed and validated through extensive simulations. Simulation results confirm the effectiveness of proposed approaches that outperform the best contemporary schemes found in literature. This book should be useful for university students, researchers, faculty members, application designers and people from industry.
Cannabidiol‐rich non‐psychotropic Cannabis sativa L. oils attenuate peripheral neuropathy symptoms by regulation of CB2‐mediated microglial neuroinflammation (2022)

Neuropathic pain (NP) is a chronic disease that affects the normal quality of life of patients. To date, the therapies available are only symptomatic and they are unable to reduce the progression of the disease. Many studies reported the efficacy of Cannabis sativa L. (C. sativa) on NP, but no Δ<sup>9</sup> -tetrahydrocannabinol (Δ<sup>9</sup> -THC)-free extracts have been investigated in detail for this activity so far. The principal aim of this work is to investigate the potential pain-relieving effect of innovative cannabidiol-rich non-psychotropic C. sativa oils, with a high content of terpenes (K2), compared to the same extract devoid of terpenes (K1). Oral administration of K2 (25 mg kg<sup>-1</sup> ) induced a rapid and long-lasting relief of pain hypersensitivity in a mice model of peripheral neuropathy. In spinal cord samples, K2 reduced mitogen-activated protein kinase (MAPKs) levels and neuroinflammatory factors. These effects were reverted by the administration of a CB2 antagonist (AM630), but not by a CB1 antagonist (AM251). Conversely, K1 showed a lower efficacy in the absence of CB1/CB2-mediated mechanisms. In LPS-stimulated murine microglial cells (BV2), K2 reduced microglia pro-inflammatory phenotype through the downregulation of histone deacetylase 1 (HDAC-1) and nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor (IKBα) and increased interleukin-10 (IL-10) expression, an important antiinflammatory cytokine. In conclusion, these results suggested that K2 oral administration attenuated NP symptoms by reducing spinal neuroinflammation and underline the important role of the synergism between cannabinoids and terpenes.
Seamless vertical handoff using Authentication Certificate in GPRS-WLAN tightly coupled integrated networks (2008)

Authentication is a key requirement in security of integrated wireless networks. A Mobile Node (MN) requires to be re-authenticated whenever it performs vertical handoff in integrated wireless networks. The re-authentication causes delay in communication. If MN is not re-authenticated, it causes an even more serious problem of unauthorized entry in a network. In order to solve this problem, we have proposed a scheme for seamless vertical handoff. In proposed scheme, MN performs first authentication and gets an authentication certificate (AC) from home authentication server. The authentication servers of partner network domains share the public keys of each other. Whenever MN wants to switch its network domain, it shows an AC to authentication server of the target network. This AC is encrypted by private key of issuing server. The target network's authentication server verifies that AC using public key of issuing authority and then authenticates a valid MN. The proposed approach reduces the number of messages, costs less bandwidth for vertical handoff and ensures only authorized entry of a MN from one network to another network.
Reusable Motivational Instruction Patterns for Socially Assistive Robots (2015)

Robots are increasingly tested in socially assistive scenarios. Future applications range from dieting, coaching, tutoring to autism therapy. In order to have a successful interaction with an artificial system, these systems need to have an interactional motivation model of how to assist users and encourage them to keep on with the task. In previous work, we have investigated how to build such a model for a specific scenario (e.g. indoor cycling). In this paper we want to show how to advance this model to be generalizable for other sport scenarios like rowing or bodyweight training. Therefore, we describe our framework for coordinating interaction scenarios with socially assistive robots.
e0009 Multimodality molecular imaging of adipose-derived mesenchymal stem cells with VEGF in hindlimb ischaemia mice (2010)

Background Peripheral arterial disease (PAD) is highly prevalent and particularly in elders, smokers, diabetics or patients with systemic atherosclerosis. Apart from the surgery and medication, stem cell transplantation offers promising approaches for therapeutic angiogenesis and tissue repair. In this study we try to use in vivo multimodality molecular imaging strategies to investigate adipose tissue-derived mesenchymal stem cells (MSCs) survival, function and relative mechanism. Method MSCs were cultured from murine adipose tissue from transgenic mice, which carried double reporter genes: firefly luciferase (Fluc) and enhanced green fluorescent protein (eGFP), by collagenase digestion method. Hindlimb ischaemia animal model was created in male nude mice by ligating the proximal and distal femoral artery. MSCs (1×10 5 ) along with/without VEGF (0.4 ng) were transplanted into ischaemic hindlimb. The animals were subjected to be imaged by bioluminescence imaging and CT scan. Laser Doppler perfusion imaging (LDPI) were used to show the spatiotemporal images of peripheral tissue blood perfusion. Micro-CT, histological and molecular analysis were tested to confirm the cells' location and angiogenesis anatomically and mechanically. Result The colour-coded index of LDPI was significantly higher in the MSCs-transplanted group than that in the control group from day 3 to 28 post cell transplantation. On day 3 after transplantation, the bioluminescence signals in MSCs with VEGF group were 4.6×10 6 ±2.5×10 5 photons/s/cm 2 /sr, while in MSCs group were 2.8×10 6 ±3.1×10 5 photons/s/cm 2 /sr, respectively (p&lt;0.01 vs control). The signals of bioluminescence increased gradually from POD 3 to day 21, which proved survival and proliferation of the MSCs in the host. The group treated with MSCs and VEGF showed higher signals than that injected by MSCs only, which indicated the reinforcement of VEGF. Micro-CT angiography demonstrated more angiogenesis in the hindlimbs of the treated mice on day 21, which were also confirmed by molecular analysis. Histological analysis showed that MSCs therapy recovered vessel density compared with the control group. Conclusion Bioluminescence fusion with CT scan provides higher detailed 3D imaging for monitoring MSCs in vivo. Angiogenesis activator VEGF might promote MSCs' beneficial function for hindlimb ischaemia therapy.
Towards Efficient Simultaneous Speech Translation: CUNI-KIT System for Simultaneous Track at IWSLT 2023 (2023)

In this paper, we describe our submission to the Simultaneous Track at IWSLT 2023. This year, we continue with the successful setup from the last year, however, we adopt the latest methods that further improve the translation quality. Additionally, we propose a novel online policy for attentional encoder-decoder models. The policy prevents the model to generate translation beyond the current speech input by using an auxiliary CTC output layer. We show that the proposed simultaneous policy can be applied to both streaming blockwise models and offline encoder-decoder models. We observe significant improvements in quality (up to 1.1 BLEU) and the computational footprint (up to 45% relative RTF).
A reactor system for studying the interactions between alkali vapors and ceramic compounds (1987)

The kinetics and mechanism of interaction between alkali vapors and several ceramic compounds are studied. A unique micro-gravimetric reactor is designed and utilized for this study. Bauxite and kaolin are very good adsorbents for alkali chlorides and are potentially good additives for control of alkali during coal combustion and gasification. The experimental data shows that the alkali capturing process is a combination of physisorption, chemisorption and chemical reaction. An analytical model is developed assuming a multi-layer adsorption of alkali on substrate followed by a rate-controlling rection on the surface. The experimental results and model predictions are in good agreement.
Abstract 10325: Epicardial Erythropoietin Patch Improves Cardiac Functions and Induces Stem Cell Associated Regeneration After Myocardial Infarction (2013)

High-dose intramyocardial Erythropoietin (EPO) therapy protects the myocardium from ischemic injury and promotes beneficial remodelling. We investigated the therapeutic efficacy of EPO at a moderate dose level and compared local and systemic delivery routes in a rat myocardial infarction (MI) model. Following MI, EPO (300 U/kg) was delivered immediately by intraperitoneal (EPO-S, n=25) injection, intramyocardial (EPO-L, n=23) injection or epicardially as an EPO-plus-fibrin patch (EPO-X, n=26). Groups were compared to each other and MI control groups with saline injections (MIC, n=25) or saline-plus-fibrin patch application (MIC-X, n=29). Heart functions were examined under baseline and Dobutamine-induced stress conditions using conductance catheter method 6 weeks after MI. Moreover, blood and myocardium were analysed including candidate genes and proteins at early (24 hours) and late (6 weeks) stages after MI. Results illustrated superior cardiac functions and healing in EPO-X compared with all groups at ...

Compounds <b>2</b>, <b>5</b>, <b>9</b>, <b>10</b>, <b>11</b> and <b>12</b> showed a good <i>in-vitro</i> anti-inflammatory activity using proteinase inhibitory assay. On the contrary, all tested compounds were inactive as antileishmanial or antimalarial.
Modern advances in microscopy: from animal to atom. (1993)

The ultimate goal of the modern physiologist is to understand and integrate the biochemistry, biophysics and physiology of undisturbed living cells. To accomplish this goal requires the development and application of approaches that can non-invasively probe a variety of dynamic cellular processes. Although no technique is truly non-invasive, recently developed methods are approaching this objective. Fluorescence has become the most popular optical tool for measuring the ion properties inside living cells, due to sensitivity, specificity, and spatial and temporal resolution. All of these systems use the same basic principle, i.e., the cell or tissue is exposed to a concentrated specific beam of excitation light and the resultant fluorescent signal is detected on a collection device. Photomultiplier tube systems will give maximal temporal resolution. Intensified video camera systems allow for maximal spatial resolution, and simultaneous measurement of fields of cells. Improved spatial resolution can be obtained using confocal microscopes providing both 2D and 3D molecular distribution and activity maps from within cells. In addition to obtaining spatial information from within cells, it is now possible to measure dynamic surface morphometric changes with Angstrom level resolution using the technique of Atomic Force Microscopy (AFM). This review will summarize the different uses of both conventional and nonconventional microscopy to examine dynamic changes in living cells.
