Virtual lesson and its application to virtual calligraphy system (2002)

The concept of a virtual lesson is proposed for transferring a teacher's skill to a student using haptic virtual reality technology. We have developed a virtual calligraphy system as one of its applications. In this system, the position and force trajectories of the teacher's writing brush is recorded first and then these trajectories are displayed to the student. What the student can learn is the teacher's horizontal brush position trajectory, his normal pushing force against a virtual paper, and the distance between the teacher's brush and the virtual paper. Recognizing that it is impossible to display both the normal force information and the normal position information at the same time, we have implemented two methods of skill display: one is to use the haptic display device for displaying the position information, and the other is to use it for displaying the force information. The remaining information is displayed using a secondary display device, visual display in the developed system. A preliminary experimental result is also presented.
Actin Microfilaments are Required for the Expression of Nonhost Resistance in Higher Plants (1997)

We investigated the role of actin microfilaments in nonhost resistance of higher plants. Here we present several lines of evidence to indicate that microfilaments are indeed involved in blocking fungal penetration of nonhost plants. Erysiphe pisi, a pathogen of pea, normally fails to penetrate into nonhost plants such as barley, wheat, cucumber and tobacco. When tissues of these nonhost plants were treated with cytochalasins, specific inhibitors of actin polymerization, this fungus became able to penetrate and formed haustoria in epidermal cells of these plants. Moreover, treatment of these plants with various kinds and concentrations of cytochalasins allowed several other non-pathogenic fungi, E.graminis hordei, E.graminis tritici, Sphaerotheca fuliginea, Colletotrichum graminicola, My-cosphaella pinodes, C. lagenarium, Altemaria kikuchiana and Corynespora melonis, to also penetrate the cells of these plants. The degree of microfilament depolymeriza-tion varied depending on the kinds and concentrations of cytochalasins applied and we show that this is significantly correlated with the penetration efficiency of C. graminicola. This indicates that the polymerized, filamentous state of actin is necessary for plants to block fungal penetration. These results strongly suggest that actin microfilaments may play important roles in the expression of nonhost resistance of higher plants.
Purification and Antiradical Properties of the Structural Unit of Betalains (2012)

Betalamic acid [4-(2-oxoethylidene)-1,2,3,4-tetrahydropyridine-2,6-dicarboxylic acid] is a naturally occurring compound that is normally found condensed with amino acids, amines, cyclo-DOPA, and cyclo-DOPA derivatives to form the betalains. Betalains are the pigments responsible for the yellow to violet color of the fruits and flowers of plants belonging to the order Caryophyllales. Betalamic acid is the structural feature common to all of these pigments and contains the electron resonance system responsible for the spectroscopic properties. Betalamic acid was purified by chromatography and identified by UV-vis spectrophotometry and ESI mass spectrometry. The antioxidant and free radical scavenging capacities of betalamic acid were assessed using the FRAP and ABTS(·+) radical assays. A pK(a) of 6.8 was found for the deprotonation equilibrium involved in the nucleophilic activity of betalamic acid; this pK(a) explains the observed pH effect on the free radical scavenging capacity of these pigments.
Additional disinfectants effective against the amphibian chytrid fungus Batrachochytrium dendrobatidis (2007)

Chytridiomycosis, a disease contributing to amphibian declines worldwide, is caused by the fungus Batrachochytrium dendrobatidis. Identifying efficient and practical disinfectants effective against B. dendrobatidis is important to reduce the spread of the disease both in the wild and captivity. Previous studies identified a range of suitable disinfectant strategies. We evaluated the suitability of 3 additional disinfectants: two of these (TriGene Virucidal Disinfectant Cleaner and F10 Super Concentrate Disinfectant) are mixtures of chemicals and one (Betadine Antiseptic Liquid) contains a single active ingredient, povidone iodine. The disinfectants were tested using a range of concentrations for 1,5 and 10 min to determine their ability to kill B. dendrobatidis in vitro. The measure of effectiveness was 100% kill of zoosporangia grown in multiwell plates. All disinfectants had a 100% efficacy at concentrations recommended by the manufacturers. The lowest concentrations capable of 100% kill after exposure for 1 min were 0.1 ml l(-1) for TriGene, 0.33 ml l(-1) for F10 and 100 ml l(-1) for Betadine. TriGene is the most effective disinfectant yet to be found, and both TriGene and F10 are more effective than various disinfectants tested in previous studies. TriGene and F10 are considered suitable for use in the field, as only small amounts of concentrate are needed.
<title>Retrieval based on image content using DC-image</title> (2001)

In this paper the method is presented to retrieve based on image content in video database using DC-image. The DC-image with the DC coefficient is extracted from DCT domain of image in this video database model. The principle of DC-image and three different extraction methods of the DC-image from MPEG video stream are described. With the DC-image, temporary segmentation of compress video is realized depending the histogram of DC-image. Comparing the performance of three extracting methods and analyzing the result of DC-image extracted by different methods, we propose a video database structure and feature extraction method. To create the uniform indexing for video clip, the expression format of frame is developed by normalized histogram of DC-image.

Antimicrobial Susceptibility Testing Predicts Treatment Success in Bacteroides Bacteremia (2000)

Clinicians rely heavily on in vitro antimicrobial susceptibility when selecting agents to treat infections caused by aerobic pathogens. Many laboratories do not provide routine testing of anaerobic isolates because of expense, uncertainty as to the clinical predictability of results, and lack of accepted methodology. Over a 4-year period, bacteroides species isolated …
The Magic Mirror: American Constitutional and Legal History. (1986)

We studied 4063 pregnant women during 4108 gestations for evidence of infection with Epstein-Barr virus. Forty-six (1.1%) were susceptible early in gestation, and only three showed seroconversion. Two of the infants born to these three women were normal, one had tricuspid atresia. None of the infants had IgM antibodies to EBV at birth, and their cord blood lymphocytes did not give rise spontaneously to EBV-carrying lymphoblastoid cell lines. Thus we were unable to document intrauterine infection with EBV.
Structural, Dielectric and Magnetoelectric Properties of x Co0.8Ni0.2Fe2O4+ (1-x) PbZr0.55Ti0.45O3Composites (2015)

In this paper, we are reporting structural, dielectric, ferroelectric and magnetic properties of polycrystalline composites (ferrite and ferroelectric) of PZT (PbZr0.55Ti0.45O3) + CNFO (Co0.8Ni0.2Fe2O4). The sample with composition x CNFO + (1-x) PZT (x = 0.00, 0.05, 0.10, 0.15 and 1.00) were prepared using the solid state double sintering method. Here the ratio x: (1-x) of two components is by weight. X-ray diffraction (XRD) studies show that lattice constant and tetragonality decreases with increasing ferrite content. Dielectric constant was found to decrease with increase in amount of CNFO. The value of tangent loss (tanδ) was reasonably low (< 0.04) for all the samples. Ferroelectric and ferrimagnetic behavior was confirmed by observing P-E and M-H hysteresis loop, respectively. The room temperature magnetoelectric coupling coefficient (α = dE/dH) was measured as a function of applied DC magnetic field. The value of α was observed to be maximum (855 μV/(cm.Oe)) at DC magnetic field of 1.7 kOe for sample with 5% CNFO. Value of piezoelectric coefficient ‘d33’ decreases from 133 to 60 pC/N.
An Illuminating Look at Fiber-Optic Transmission Systems (1987)

Fiber-optic technology can be applied to many corporate networks and is well suited for many specialized applications involving high-speed data transmission between terminals and a computer or between computers located in the same building. This article describes the components of fiberoptic transmission systems and examines the advantages and disadvantages of these systems.
Modulation of Erythrocyte Plasma Membrane Redox System Activity by Curcumin (2016)

Plasma membrane redox system (PMRS) is an electron transport chain system ubiquitously present throughout all cell types. It transfers electron from intracellular substrates to extracellular acceptors for regulation of redox status. Curcumin, isolated from Curcuma longa, has modulatory effects on cellular physiology due to its membrane interaction ability and antioxidant potential. The present study investigates the effect of curcumin on PMRS activity of erythrocytes isolated from Wistar rats in vitro and in vivo and validated through an in silico docking simulation study using Molegro Virtual Docker (MVD). Effects of curcumin were also evaluated on level of glutathione (GSH) and the oxidant potential of plasma measured in terms of plasma ferric equivalent oxidative potentials (PFEOP). Results show that curcumin significantly (p < 0.01) downregulated the PMRS activity in a dose-dependent manner. Molecular docking results suggest that curcumin interacts with amino acids at the active site cavity of cytochrome b 5 reductase, a key constituent of PMRS. Curcumin also increased the GSH level in erythrocytes and plasma while simultaneously decreasing the oxidant potential (PFEOP) of plasma. Altered PMRS activity and redox status are associated with the pathophysiology of several health complications including aging and diabetes; hence, the above finding may explain part of the role of curcumin in health beneficial effects.
Detection of carbon dioxide embolism by transesophageal echocardiography during transanal/perineal endoscopic surgery: a pilot study (2022)

The transanal/perineal (ta/tp) endoscopic approach has been widely used for anorectal surgery in recent years, but carbon dioxide embolism is a possible lethal complication. The frequency of this complication in this approach is not known. In this study, we investigated the frequency of intraoperative (including occult) carbon dioxide embolism using transesophageal echocardiography. Patients who underwent surgery via the ta/tp approach and consented to participate were included. Intraoperative transesophageal echocardiography was used to observe the right ventricular system in a four-chamber view. Changes in end-tidal carbon dioxide (EtCO<sub>2</sub>), oxygen saturation (SpO<sub>2</sub>), and blood pressure were taken from anesthesia records. Median maximum insufflation pressure during the ta/tp approach was 13.5 (12-18) mmHg. One patient (4.8%) was observed to have a bubble in the right atrium on intraoperative transesophageal echocardiography, with a decrease in EtCO<sub>2</sub> from 39 to 35 mmHg but no obvious change in SpO<sub>2</sub> or blood pressure. By lowering the insufflation pressure from 15 to 10 mmHg and controlling bleeding from the veins around the prostate, the gas rapidly disappeared and the operation could be continued. Among all patients, the range of variation in intraoperative EtCO<sub>2</sub> was 5-22 mmHg, and an intraoperative decrease in EtCO<sub>2</sub> of > 3 mmHg within 5 min was observed in 19 patients (median 5 mmHg in 1-10 times).Clinicians should be aware of carbon dioxide embolism as a rare but potentially lethal complication of anorectal surgery, especially when using the ta/tp approach.

Enhanced Disinfection Effect of a Compound Disinfectant against Bovine Herpes Virus Type 1 at Low Temperature (2013)

A compound disinfectant, which consisted of didecyldimethylammonium chloride (DDAC), ortho-dichlorobenzene (1,2-dichlorobenzene, ODB), and chlorocresol (4-chloro-3-methylphenol, CC), and its component chemicals were individually tested for effectiveness against bovine herpes virus type 1 (BHV-1). DDAC, DDAC+ODB, DDAC+CC, and DDAC+ODB+CC showed effectiveness against BHV-1 at room temperature. However, ODB, CC, and ODB+CC showed no virucidal effects. The effects of all disinfectants tested were decreased at low temperature. DDAC showed disinfectant effects at a dilution of 1/800 and DDAC+ODB, DDAC+CC, and DDAC+ODB+CC at dilutions of 1/800 and 1/1600 at low temperature in the presence of 2% fetal bovine serum (FBS) but ODB, CC, and ODB+CC showed no virucidal effects. At low temperature and in the presence of 10% FBS, DDAC, DDAC+ODB, and DDAC+CC showed disinfectant effects at dilutions of 1/800, whereas ODB, CC, and ODB+CC showed no virucidal effects. DDAC+ ODB+CC was more effective (at 1/800 and 1/1600) than the other disinfectants under these conditions. In conclusion, a combination of three disinfectant components (DDAC+ODB+CC), enhanced the disinfectant effects at low temperature and in organic matter contamination.
A framework of data caching for improving decoding efficiency of opportunistic network coding (2013)

SUMMARY Throughput performance of wireless networks can be enhanced by applying network coding (NC) technique based on opportunistic listening. The packets sent or overheard by a network node should be locally cached for the purpose of possible future decoding. How to manage the cache to reduce the overhead incurred in performing NC and, meanwhile, exploit performance gain is an interesting issue that has not been deeply investigated. In this paper, we present a framework for packet caching policy in multihop wireless networks, aiming at improving decoding efficiency, and thus throughput gain of NC. We formulate the caching policy design as an optimization problem for maximizing decoding utility and derive a set of optimization rules. We propose a distributed network coding caching policy (NCP), which can be readily incorporated into various existing NC architectures to improve NC performance gain. We theoretically analyze the performance improvement of NCP over completely opportunistic NC (COPE). In addition, we use simulation experiments based on ns‐2 to evaluate the performance of NCP. Numerical results validate our analytical model and show that NCP can effectively improve the performance gain of NC compared with COPE. Copyright © 2013 John Wiley &amp; Sons, Ltd.
Direct Access to β-Oxodiazo Compounds by Copper(II)-Catalyzed Oxidative Rearrangement of Stabilized Vinyl Diazo Derivatives (2011)

The copper(II)-catalyzed reaction of alkenyldiazo compounds with iodosylbenzene leading to β-oxodiazo derivatives is reported. This process occurs via an unprecedented 1,2-shift of the diazoacetate function. A selection of the synthetic applications of a representative member of this new class of functionalized diazo derivatives in the regioselective synthesis of substituted 1,4-dicarbonyl compounds is also reported.
Assembly and transport of MHC class II molecules. (1992)

At the surface of antigen-presenting cells MHC class I and class II molecules present peptides to respectively CD8+ and CD4+ T cells. MHC class I molecules acquire peptides right after synthesis in the endoplasmic reticulum. MHC class II molecules do not acquire peptides in the endoplasmic reticulum but instead associate with a third chain, the invariant chain which impedes peptide binding. Subsequently the invariant chain takes MHC class II molecules to the endosomal/lysosomal compartment thanks to a targeting signal retained in its cytoplasmic tail. It then dissociates from the MHC class II dimer to allow it to bind peptides.
Psychological characteristics and associations between living kidney transplantation recipients and biologically related or unrelated donors (2020)

Recipients suffered from a higher level of depression and somatic concerns than donors before living kidney transplantation. Psychological problems like depression and anxiety can occur in both living kidney transplantation donors and recipients. This study suggests that clinicians must pay attention to mood states not only in recipients but also in donors because of emotional contagion.

The AMICA-PROBE is a safe, well-tolerated, and repeatable method to treat BPH with microwave thermotherapy. The spheroid lesions obtained demonstrated the maximal control over the radial and longitudinal coagulative effects of the therapy. Phase II studies are needed to further evaluate the efficacy of this new probe.
Antiviral Natural Products and Herbal Medicines (2014)

Viral infections play an important role in human diseases, and recent outbreaks in the advent of globalization and ease of travel have underscored their prevention as a critical issue in safeguarding public health. Despite the progress made in immunization and drug development, many viruses lack preventive vaccines and efficient antiviral therapies, which are often beset by the generation of viral escape mutants. Thus, identifying novel antiviral drugs is of critical importance and natural products are an excellent source for such discoveries. In this mini-review, we summarize the antiviral effects reported for several natural products and herbal medicines.
Register Cache System Not for Latency Reduction Purpose (2010)

A register cache has been proposed to solve the problems of the huge register files of recent super scalar processors. The register cache reduces the effective access latency of the register file for IPC improvement, simplifies the bypass network, and reduces the ports of the main register file. Though the primary purpose of the previous works is to improve IPC, the misses on the register cache may degrade the IPC. We propose Non-Latency-Oriented Register Cache System (NORCS). Though the effects of NORCS are the same as the conventional systems, it is free from register cache miss penalties that the conventional systems suffer from. In NORCS, the register cache itself is not different from that of the conventional systems. The difference is that the instruction pipeline has stages to read the main register file, which all instructions go through regardless of register cache hit / miss. Therefore, the instruction pipeline of NORCS is not immediately disturbed by the register cache misses. For a realistic 4-way super scalar processor, NORCS can simplify the bypass network to the same complexity as a 1-cycle-latency register file, and reduce the ports of the main register file from 12 to 4. CACTI simulation shows that the area and power consumption are reduced to 24.9% and 31.9% compared to the baseline model without register cache. Though these results are not different from the conventional systems, IPCs differ greatly. IPC of the conventional system decreases to 83.1% because of the cache miss penalties, while that of NORCS is retained at 98.0%.
Penetration of amoxycillin, ticarcillin and clavulanic add into lymph after intravenous infusion in rabbits to simulate human serum pharmacokinetics (1990)

The distribution of amoxycillin, ticarcillin and clavulanic acid into lymph collected from the right lymphatic duct of rabbits was examined after intravenous administration. The compounds were administered to simulate, in the plasma of rabbits, the concentrations of amoxycillin, ticarcillin and clavulanic acid measured in human serum after the administration of either an iv bolus dose of amoxycillin 1.0 g plus clavulanic acid 200 mg, ticarcillin 3.0 g plus clavulanic acid 200 mg, or an iv infusion of amoxycillin 2.0 g plus clavulanic acid 200 mg or ticarcillin 3.0 g plus clavulanic acid 200 mg given over 30 min. Lymph concentrations of the compounds reached a peak rapidly after the simulation of a bolus dose (0-1 h) and the concentration-versus-time profiles in plasma and lymph were generally similar after 45 min. Following simulation of an iv infusion, peak concentrations of amoxycillin and clavulanic acid in lymph were reached at approximately the same time as for the bolus simulation, but that of ticarcillin occurred slightly later. The elimination half-lives of the compounds were similar in plasma and lymph. The percentage penetration values were high (greater than 80%) irrespective of the concentration-versus-time curve simulated. The penetration of clavulanic acid was compatible with that of the coadministered penicillin agent and was similar when given with either amoxycillin or ticarcillin.
