Facial color is an efficient mechanism to visually transmit emotion (2018)

Facial expressions of emotion in humans are believed to be produced by contracting one's facial muscles, generally called action units. However, the surface of the face is also innervated with a large network of blood vessels. Blood flow variations in these vessels yield visible color changes on the face. Here, we study the hypothesis that these visible facial colors allow observers to successfully transmit and visually interpret emotion even in the absence of facial muscle activation. To study this hypothesis, we address the following two questions. Are observable facial colors consistent within and differential between emotion categories and positive vs. negative valence? And does the human visual system use these facial colors to decode emotion from faces? These questions suggest the existence of an important, unexplored mechanism of the production of facial expressions of emotion by a sender and their visual interpretation by an observer. The results of our studies provide evidence in favor of our hypothesis. We show that people successfully decode emotion using these color features, even in the absence of any facial muscle activation. We also demonstrate that this color signal is independent from that provided by facial muscle movements. These results support a revised model of the production and perception of facial expressions of emotion where facial color is an effective mechanism to visually transmit and decode emotion.
Focused-ion beam patterning of organolead trihalide perovskite for subwavelength grating nanophotonic applications (2015)

The coherent amplified spontaneous emission and high photoluminescence quantum efficiency of organolead trihalide perovskite have led to research interest in this material for use in photonic devices. In this paper, the authors present a focused-ion beam patterning strategy for methylammonium lead tribromide (MAPbBr3) perovskite crystal for subwavelength grating nanophotonic applications. The essential parameters for milling, such as the number of scan passes, dwell time, ion dose, ion current, ion incident angle, and gas-assisted etching, were experimentally evaluated to determine the sputtering yield of the perovskite. Based on our patterning conditions, the authors observed that the sputtering yield ranged from 0.0302 to 0.0719 μm3/pC for the MAPbBr3 perovskite crystal. Using XeF2 for the focused-ion beam gas-assisted etching, the authors determined that the etching rate was reduced to between 0.40 and 0.97, depending on the ion dose, compared with milling with ions only. Using the optimized patterning parameters, the authors patterned binary and circular subwavelength grating reflectors on the MAPbBr3 perovskite crystal using the focused-ion beam technique. Based on the computed grating structure with around 97% reflectivity, all of the grating dimensions (period, duty cycle, and grating thickness) were patterned with nanoscale precision (&gt;±3 nm), high contrast, and excellent uniformity. Our results provide a platform for utilizing the focused-ion beam technique for fast prototyping of photonic nanostructures or nanodevices on organolead trihalide perovskite.

Effect of Anti-CD14 Antibody on Experimental Periodontitis Induced by Porphyromonas gingivalis Lipopolysaccharide (2002)

The lipopolysaccharide (LPS) released by Porphyromonas gingivalis, a Gram-negative bacterium found in the periodontal pockets of patients with periodontitis, induces bone resorbing activity in vivo. We previously showed that a receptor for LPS on human gingival fibroblasts and gingival epithelial cells is CD14. In this study, we established a mouse model of experimental periodontitis by applying a P. gingivalis LPS solution to the buccal region of mice. P. gingivalis LPS-induced bone resorption and interleukin-6 production in the gingival tissues were significantly inhibited by pretreatment with anti-CD14 antibody for 5 weeks prior to LPS treatment. This result suggests that anti-CD14 antibody may be usable as a prototype for the development of drugs for the treatment of periodontal disease.
Compositional and gate tuning of the interfacial conductivity in LaAlO3/LaTiO3/SrTiO3 heterostructures (2013)

We investigate the effect of LaTiO3 insertion at the interface between LaAlO3 and TiO2 terminated {100} SrTiO3 for a series of LaAlO3 and LaTiO3 thicknesses. A clear increase of the carrier density was observed while the Hall mobility was largely unchanged. In structures with LaAlO3 thickness ∼3 unit cells, close to the critical thickness for conductivity, as little as 0.25 unit cells of LaTiO3 drives an insulator-to-metal transition. These samples show a strong dependence of the conductivity on voltage with electrostatic back-gating, which can be understood in a two-carrier picture, and dominated by the change in carrier density at the interface.
An automated reasoning method used in workflow management system (2004)

In the workflow management system, the process definition is finished by the process definition tools and explained and enacted by the workflow enactment service. The method that the application logic and the process logic are separated improves the reuse rate of the software and the efficiency of the system by modifying the process model rather than the material functions. We propose an automated reasoning method to validate the process definition in this paper. The method includes two steps. In the first step, the typical relationship between the activities is discussed, and then the transformation rules from the relevant activities to a clause set is given; the automated reasoning based on path searching is proposed for judging the satisfiability of the clause set and finding out the validation of the process definition in the second step. Experimental results show that this method is effective for WfMS.

Carbonic Anhydrase III. OXIDATIVE MODIFICATION IN VIVO AND LOSS OF PHOSPHATASE ACTIVITY DURING AGING (1995)

Oxidative modification of DNA, lipids, and proteins occurs as a consequence of reaction with free radicals and activated oxygen. Oxidative modification of total cellular proteins has been described under many pathologic and experimental conditions, but no specific proteins have been identified as in vivo targets for oxidative modification. Utilizing an immunochemical method for detection of oxidatively modified proteins, we identified a protein in rat liver that was highly oxidized. It was purified to homogeneity and identified as carbonic anhydrase, isozyme III. Its characteristics match those previously described for a protein that was lost during aging of the rat, senescence marker protein-1. Carbonic anhydrase III was purified from rats aged 2, 10, and 18 months, and the proteins were characterized. All three preparations were highly oxidatively modified as assessed by their carbonyl content. The enzyme has three known catalytic activities, and the specific activities for carbon dioxide hydration and for ester hydrolysis decreased during aging by approximately 30%. However, the third activity, that of a phosphatase, was virtually lost during aging. While the physiologic role of carbonic anhydrase III is unknown, we suggest that it functions in an oxidizing environment, which leads to its own oxidative modification.
A fast fanout optimization algorithm for near-continuous buffer libraries (1998)

This paper presents a gain-based fanout optimization algorithm for near-continuous buffer libraries. A near-continuous buffer library contains many buffers in a wide range of discrete sizes and each buffer of a specific type satisfies a size-independent delay equation. The new fanout algorithm is derived from an optimal algorithm to a special fanout optimization problem for continuous libraries. The gain-based technique constructs fanout trees which have better timing at similar area cost. Since no combinatorial search over buffer sizes or fanout tree topologies is used, our execution time is up to 1000 times faster when compared to conventional fanout algorithms.
New Celecoxib Derivatives as Anti-Inflammatory Agents (2007)

A series of 1,5-diarylpyrazoles with a substituted benzenesulfonamide moiety was synthesized and evaluated for cyclooxygenase (COX-1/COX-2) inhibitory activities. Some compounds, for example, (+/-)-2-[4-(5- p-tolyl-3-trifluoromethyl-pyrazole-1-yl)-benzenesulfonylaminooxy]-propionic acid 16 and its disodium salt 21, had a higher in vivo anti-inflammatory activity compared to celecoxib, despite having no in vitro COX-1 or COX-2 inhibitory activity. Their gastrointestinal side effect profile is essentially more favorable than that of celecoxib.
Properties of Poly(diphenylsilylenemethylene) Thin Films Fabricated with Fine Metal Particles (1999)

The properties of poly(diphenylsilylenemethylene) (PDPhSM) thin films were studied. These films were fabricated by a new polymerization technique using ultrafine sputtered metal particles as catalysts. It was shown that the metal particles were spread over the film surface before polymerization, but migrated inside the films during the polymerization to form a three-dimensional distribution. The surface morphology and crystallinity of the films were greatly affected by the metal species used. The surface roughness of the films ranged from 2 to 400 nm, depending on the metal, but could be adjusted within the range by use of a combination of several metals. The thermal stability tended to increase with the crystallinity of the film. The polymer films showed the same long lifetime visible light emission upon UV laser irradiation as those already reported for chemically synthesized polymers.
Novel Antibiofilm Chemotherapy Targets Exopolysaccharide Synthesis and Stress Tolerance in Streptococcus mutans To Modulate Virulence Expression <i>In Vivo</i> (2012)

Fluoride is the mainstay of dental caries prevention, and yet current applications offer incomplete protection and may not effectively address the infectious character of the disease. Therefore, we evaluated the effectiveness of a novel combination therapy (CT; 2 mM myricetin, 4 mM tt-farnesol, 250 ppm of fluoride) that supplements fluoride with naturally occurring, food-derived, antibiofilm compounds. Treatment regimens simulating those experienced clinically (twice daily for ≤60 s) were used both in vitro over a saliva-coated hydroxyapatite biofilm model and in vivo with a rodent model of dental caries. The effectiveness of CT was evaluated based on the incidence and severity of carious lesions (compared to fluoride or vehicle control). We found that CT was superior to fluoride (positive control, P < 0.05); topical applications dramatically reduced caries development in Sprague-Dawley rats, all without altering the Streptococcus mutans or total populations within the plaque. We subsequently identified the underlying mechanisms through which applications of CT modulate biofilm virulence. CT targets expression of key Streptococcus mutans genes during biofilm formation in vitro and in vivo. These are associated with exopolysaccharide matrix synthesis (gtfB) and the ability to tolerate exogenous stress (e.g., sloA), which are essential for cariogenic biofilm assembly. We also identified a unique gene (SMU.940) that was severely repressed and may represent a potentially novel target; its inactivation disrupted exopolysaccharide accumulation and matrix development. Altogether, CT may be clinically more effective than current anticaries modalities, targeting expression of bacterial virulence associated with pathogenesis of the disease. These observations may have relevance for development of enhanced therapies against other biofilm-dependent infections.
In Search of Pathogenic Mechanisms in Endometriosis: The Challenge for Molecular Cell Biology (2001)

Endometriosis, defined histologically as the presence of endometrium-like glands and stroma outside the uterus, is a chronic, invasive and metastasising disease. It shares features with malignant tumours (invasion and metastasis) but is not neoplastic. Despite the fact that endometriosis is one of the most frequent gynaecological diseases, it is under researched, puzzling and highly debated. The aetiology and pathogenesis is little understood although it is agreed that implantation, at least in many cases, is responsible for endometriosis. This theory advocates retrograde menstruation as the underlying phenomenon, where cells of the menstrual efflux provide the cellular source for endometriotic lesion formation. Causative therapy and non-invasive diagnostics of endometriosis do not exist. Thus, there is a substantial but unmet need for molecular and cellular research to unravel the pathogenic mechanisms of endometriosis as a basis for developing novel diagnostic and therapeutic concepts. In this review, we specifically focus on the cellular basis of lesion formation, the possible modulation of this by cytokines and other factors and the characteristics of endometriotic cells in terms of invasion and metastasis. Considering available experimental information, we concentrate on arguments and ideas in favour of an endometriotic founder cell population exhibiting substantial plasticity for differentiation and self-renewal. Perhaps present in the menstrual efflux or arising by metaplasia (a complementary theory to implantation), this cell type might respond to stimuli present in the ectopic host environment and establish the endometriotic phenotype.
Using dual-antenna nanosecond pulse near-field sensing technology for non-contact and continuous blood pressure measurement (2012)

Long-term and continuous non-invasive blood pressure monitoring has shown that it is the most important to clinical diagnosis of cardiovascular diseases and personal home health care. Currently, there are many preferable non-invasive methods, including optical sensor, pressure-sensitive transducers, and applanation tonometry, to get insight of blood pressure and flow signal detection. However, the operation of traditional monitors is cuff accessories needed, and also the sensing probes needed to exert pressure to the user directly. The measurement procedure is limited by long-term, continuous measurement and also easy to cause discomfort. To improve these issues, the non-pressurized and non-invasive measuring method will become an important innovation improvement. In this paper, the novel nanosecond pulse near-field sensing (NPNS) based screening technology with dual-antenna, which includes radio frequency (RF) pulse transmission and two combined flat antenna connected to transceiver of miniature radar, is proposed to derive relative blood pressure parameters from measured blood flow activity (Pulse Wave Velocity, PWV). A dedicated analysis software is also provided to calculate cardiovascular parameters, including PWV, average systolic time, diastolic and systolic pressure, for clinical and homecare applications. To evaluate the performance, the proposed method was applied on blood pressure measurement at the body site of limbs (brachial and leg). As a result, it shows error of DBP and SBP is 5.18 ± 1.61 and 4.09 ± 1.69 mmHg in average compared with the measurement result from commercial product, and performs the capability of continuous long-term monitoring in real-time.
Role of Xanthine Oxidase in Reperfusion Injury In Ischemic Myocardium (1988)

The present studies were conducted to confirm the hypothesis that xanthine oxidase-\nlinked cytotoxic oxygen free radicals play an important role in producing the reperfusion\ninjury of ischemic myocardium. The reperfusion injury was induced in isolated, Langendorff\npreparations of rat hearts by 60 min of global ischemia with aortic clamping followed by 20\nmin of reperfusion with oxygenated Krebs- Henseleit solution. Upon reperfusion of ischemic\nhearts, the release of creatine phosphokinase, lactic dehydrogenase and a lipid peroxidation\nproduct, malondialdehyde into the coronary effluent was abruptly increased. The increase of\nthe enzymes and malondialdehyde was supprressed significantly in the presence of superoxide\ndismutase or catalse during the reperfusion period. In the hearts removed from rats pretreated\nwith a specific xanthine oxidase inhibitor, allopurino1(20 mglkg, orally 24 hrs and 2 hrs before\nstudy}, the increased release of the enzymes and malondialdehyde was also significantly depressed.\nThis effect of allopurinol was comparable to that of oxygen radical scavengers. When\nferricytochrome C was infused to the hearts starting with reperfusion, the SOD-inhibitable reduction\nof ferricytochrome C increased during the first minute of reperfusion. Hydrogen peroxide\nmeasured in the coronary effluents also increased markedly with the similar time course as\nferricytochrome C reduction. In the hearts treated with allopurinol, however, both the ferricytochrome\nC reduction and HzOz were not increased significantly. Myocardial content of xanthine\noxidase was determined for D-form, O-form and D/O-form separately in the normal control\nhearts and the ischemic ones. Total enzyme content was similar in both hearts. Compared\nwith the normal control, however, the ischemic hearts showed lower activities in D-form and\nD/O-form, and higher activity in the oxygen radical producing O-form. The proportion of\nO-form to the total enzyme was much higher in the ischemic heart than in the normal control\nheart. After 60 min of ischemia, myocardial content of total adenine nucleotides were reduced\nto 40% of the normal control value, while their catabolic products, hypoxanthine and xanthine\nwere accumulated significantly. These. results provide evidence that xanthine oxidase is involved\nin the production of oxygen free radicals during the reperfusion of ischemic heart, and\nplays a contributing role in the genesis of reperfusion injury.
Self-Balancing System for Medical and Physiological Instrumentation (1971)

There is a need in medical and physiological instrumentation for a system that can automatically correct baseline shifts. Some cases where this need arises are discussed. A self-balancing system that can be used as a general-purpose unit has been developed and is described. It consists of a binary counter, a digital to analog converter, and logic circuits. The described system automatically balances dc shifts in signals with a range of 6 V. Balancing time is less than 15 ms. The system is designed to work with tape or chart recorders with input range of ± 1 to ± 3 V. Some design parameters of this system are discussed briefly.
New insights into highly efficient reduction of CO<sub>2</sub>to formic acid by using zinc under mild hydrothermal conditions: a joint experimental and theoretical study (2014)

We report here a theoretical study with quantum chemical calculations based on experimental results to understand highly efficient reduction of CO2 to formic acid by using zinc under hydrothermal conditions. Results showed that zinc hydride (Zn-H) is a key intermediate species in the reduction of CO2 to formic acid, which demonstrates that the formation of formic acid is through an SN2-like mechanism.
