Loop Diuretic Therapy in Heart Failure: The Need for Solid Evidence on a Fluid Issue
Authors: Chiong Jun R. , Cheung Rebecca J. 
Published: June 2010

AbstractBackgroundHeart failure (HF) is a common condition associated with substantial cost, morbidity, and mortality. Because results of clinical trials in the acute decompensated heart failure (ADHF) setting have been mostly neutral, loop diuretics remain the mainstay of treatment.HypothesisLoop diuretic use may be associated with unfavorable outcomes.MethodsA MEDLINE literature search was performed to identify articles relating to heart failure and loop diuretics. The current evidence on the risks and benefits of loop diuretics for the treatment of ADHF is reviewed.ResultsLoop diuretics are associated with symptomatic improvements in congestion, urine output, and body weight, but have shown no long‐term mortality benefit. Loop diuretics, especially at high doses, are associated with worsened renal function and other poor outcomes.ConclusionsLoop diuretics still prove useful in HF treatment, but risk‐benefit analysis of these agents in the treatment of ADHF requires a well‐designed prospective study.

Distributed diagnosis over wireless sensors networks
Authors: Dessart Nathalie , Fouchal Hacène , Hunel Philippe 
Published: June 2010

AbstractThis paper studies how to detect anomalies in a distributed manner by using wireless sensor networks (WSNs). We focus on a medical context, where the existing works generally provide large environments to monitor patients using sensors as simple transducers. Those devices forward sensed health parameters to a main base station. This station collects received data and may perform some computations. In this paper, we perform some distributed tasks on the sensors. We propose a distributed algorithm, which allows to raise alarms under some initial rules to alert efficiently medical staff in case of critical situations without needless warnings. Each mote monitors a parameter. When this parameter reaches an abnormal value, the mote communicates with other motes in order to check if it is a ‘local’ anomaly or if the patient is in an abnormal situation. In such cases an alarm is raised. We implemented our algorithm over a network of micaZ sensors running under TinyOS. The obtained results show promising perspectives.

Change rate control of photovoltaic generation output and calculation of necessary capacitance
Authors: Satoh Hiroyuki , Takayama Satoshi , Nakamura Koichi , Kakimoto Naoto 
Published: June 2010

AbstractThe photovoltaic (PV) generator changes its power output with the weather. If the photovoltaic generator output changes fast, the power system may require more load‐following capability and spinning reserve. This paper proposes a method of controlling the change rate of the photovoltaic generator output. The photovoltaic generator is combined with an electric double layer capacitor (EDLC). A moving average is used to eliminate short period fluctuations in the photovoltaic generator output. The output of the power conversion system (PCS) is determined by the moving average. The output changes within a limited rate. The capacitor voltage is maintained at a constant value to make the capacitor as small as possible. The necessary capacitance is theoretically derived. The effectiveness of this method is verified by experiments. © 2010 Wiley Periodicals, Inc. Electr Eng Jpn, 172(4): 10–18, 2010; Published online in Wiley InterScience (www.interscience.wiley.com).

Published: June 2010

AbstractThis paper proposes a method for mobile robot self‐localization by the use of a passive RFID system and Support Vector Machines (SVMs). The use of the SVM eliminates the need for laborious measurement of the geometric position of each RFID tag. Furthermore, the method works even when several malfunctioning tags are included. The ability of the method is confirmed in tests, and we conclude that the method performs well. © 2010 Wiley Periodicals, Inc.

AC voltage and current sensorless control method for three‐phase PWM converter
Authors: Li Dongsheng , Notohara Yasuo , Iwaji Yoshitaka , Kurita Yoshiaki 
Published: June 2010

AbstractWe present a three‐phase PWM converter without AC voltage and AC current sensors. The phase angle used in the control system is adjusted by using a PLL controller without sensing AC voltage. To prevent overcurrent at startup, the initial phase angle of the source voltage is estimated from the shunt current using a novel strategy. Furthermore, the phase currents can be reconstructed from the shunt current without any modification of the PWM pattern. To reduce the effect of current ripple, the shunt current is sampled twice for every phase in one PWM period and the sample timings are carefully adjusted. All of the proposed control schemes can be implanted using a single chip microprocessor (SH7046, Renesas Tech.). Simulation and experimental results with a 5‐kW prototype confirmed that the schemes worked well. © 2010 Wiley Periodicals, Inc.

Moving object detection using strip frame images
Authors: Hoguro Masahiro , Inoue Yuki , Umezaki Taizo , Setta Takefumi 
Published: June 2010

AbstractIn existing methods of moving object detection using image recognition technology, an obtained whole image is processed and a moving object is detected in the picture. However, when the moving portion of the scene is hidden by obstacles, recognition of a moving object is sometimes difficult. In this study, we propose a novel method of discriminating moving objects, such as a person or a vehicle. We use only a narrow and tall area of the video, called the Strip Frame Image, for detecting moving portions. By using this method, we are able to obtain patterns of moving objects while avoiding obstacles in a picture. We then classify them by DP matching against previously stored reference patterns in a database for all possible classes (person, bicycle, car, bus). In this paper, we compare several variations of an algorithm used to detect and classify objects passing laterally in front of a security camera. We test both a moving object speed‐independent method and a speed‐based method for constructing patterns for the passing objects. The results show that the relatively simple method of pattern classification by DP matching can be successfully used for classifying graphic objects of a certain degree of complexity. Finally, nonhomogeneity of people's patterns and their subsequent frequent misclassification is addressed not by producing reference patterns for people, but by differentiating them from correctly classified bicycles by the DP distance to the first candidate. © 2010 Wiley Periodicals, Inc.

Synthesis of Novel Bis(β‐cyclodextrin)s Linked with Glycol and Their Inclusion Complexation with Organic Dyes

Published: June 2010

AbstractThree novel bis(β‐cyclodextrin (CD))s with flexible glycol linkers, i.e., ethylene glycol‐bridged bis(6‐hydroxy‐6‐deoxy‐β‐CD) (2), diethylene glycol‐bridged bis(6‐hydroxy‐6‐deoxy‐β‐CD) (3), and triethylene glycol‐bridged bis(6‐hydroxy‐6‐deoxy‐β‐CD) (4) have been synthesized by the reaction of mono[6‐O‐(p‐toluenesulfonyl)]‐β‐CD with corresponding materials. The inclusion complexation behaviors of these compounds 2–4 with organic dyes; that is, acridine red (=N‐[(3Z)‐6‐(methylamino)‐3H‐xanthen‐3‐ylidene]methanaminium chloride; AR), neutral red (=N8,N8,3‐trimethylphenazine‐2,8‐diamine hydrochloride; NR), ammonium 8‐anilinonaphthalene‐1‐sulfonate (ANS), sodium 6‐(p‐toluidinyl)‐naphthalene‐2‐sulfonate (TNS), rhodamine B (RhB) and brilliant green (=N‐(4‐{[4‐(diethylamino)cyclohexa‐2,5‐dien‐1‐yl](phenyl)methyl}cyclohex‐2‐en‐1‐ylidene)‐N‐ethyl‐ethanaminium hydrogen sulfate; BG), have been investigated at 25° in phosphate buffer (pH 7.20) by ultraviolet, fluorescence, and 2D‐NMR spectroscopy. The results indicate that the two linked CD units may cooperatively bind a guest, and the molecular binding ability toward dye guests, especially bent ANS, T‐shaped RhB, and triangular BG, can be extended. This cooperative binding mode is confirmed by Job's experiments and 2D‐NMR investigations. Furthermore, the complex stability depends greatly on the linker length of these glycol‐bridged bis(β‐CD)s and the size and shape of guest. The higher binding ability and selectivity of dye molecules by bis(β‐CD)s 2–4 are discussed from the viewpoint of size/shape‐fit concept and multiple recognition mechanism.

A generalized higher order kernel energy approximation method
Authors: Weiss Stewart N. , Huang Lulu , Massa Lou 
Published: June 2010

AbstractWe present a general mathematical model that can be used to improve almost all fragment‐based methods for ab initio calculation of total molecular energy. Fragment‐based methods of computing total molecular energy mathematically decompose a molecule into smaller fragments, quantum‐mechanically compute the energies of single and multiple fragments, and then combine the computed fragment energies in some particular way to compute the total molecular energy. Because the kernel energy method (KEM) is a fragment‐based method that has been used with much success on many biological molecules, our model is presented in the context of the KEM in particular. In this generalized model, the total energy is not based on sums of all possible double‐, triple‐, and quadruple‐kernel interactions, but on the interactions of precisely those combinations of kernels that are connected in the mathematical graph that represents the fragmented molecule. This makes it possible to estimate total molecular energy with high accuracy and no superfluous computation and greatly extends the utility of the KEM and other fragment‐based methods. We demonstrate the practicality and effectiveness of our model by presenting how it has been used on the yeast initiator tRNA molecule, ytRN (1YFG in the Protein Data Bank), with kernel computations using the Hartree‐Fock equations with a limited basis of Gaussian STO‐3G type. © 2010 Wiley Periodicals, Inc.

AbstractBackgroundA recurrent breast cancer patient received high‐dose chemotherapy, a transplant of multidrug resistance 1 (MDR1)‐transduced cells and four different protocols of post‐transplantation chemotherapy. We report the analysis of MDR1‐transduced cells in this patient.MethodsMDR1 transgene levels in the peripheral blood mononuclear cells of the patient were evaluated by polymerase chain reaction (PCR). Retroviral integration sites of the MDR1‐transduced cells were identified by linear amplification‐mediated (LAM)‐PCR.ResultsTwelve days after transplantation, approximately 1% of the peripheral blood mononuclear cells were MDR1 transgene‐positive. The transgene levels decreased quickly, and were at low levels until day 504. A remarkable increase in MDR1 transgene‐positive cells was observed on day 532, during combination chemotherapy with mitomycin C and methotrexate. Using LAM‐PCR, 31 MDR1‐transduced clones were identified, and eight of these were long‐life clones that survived for more than 500 days. Among the 31 clones, ten had a retroviral integration site near genes listed in the Retroviral Tagged Cancer Gene (RTCG) Database. Two long‐life clones, N‐30 and N‐31, had retroviral integration sites within the MDS1‐EVI1 locus. Another two long‐life clones had integration sites close to PRDM16 or CUEDC1.ConclusionsThese results suggest that MDR1‐transduced cells were enriched in vivo by an MDR1 substrate, mitomycin C. The possible activation of EVI1 or other RTCGs by retroviral insertion may have affected the survival and persistence of a proportion of the transduced cells. Copyright © 2010 John Wiley & Sons, Ltd.
Novel Non‐Conjugated Main‐Chain Hole‐Transporting Polymers for Organic Electronics Application

Published: June 2010

AbstractA new class of hole‐transporting polymers for use in organic electronic devices such as organic light‐emitting diodes (OLEDs) or photorefractive holographic storage devices has been synthesized. The polymers contain tetraarylbenzidines or tetraarylphenylenediamines as charge‐transporting units in the polymer backbone and are connected by non‐conjugating fluorene bridges. For use in OLEDs the novel polymers were functionalized with oxetane groups that can be cross‐linked via a cationic ring opening polymerization to yield insoluble networks. Such insoluble films are necessary for the fabrication of multilayer devices by wet deposition techniques. The novel materials feature improved film‐formation properties as demonstrated in green‐emitting double‐layer OLEDs.magnified image
Reaction of selenium and tellurium halides with propargyl alcohols. The regio‐ and stereoselectivity of addition to the triple bond

Published: June 2010

AbstractA convenient method to incorporate selenium into an organic molecule is reported. Various aspects of the reaction of SeCl2with propargyl alcohols, i.e., identity of reacting functionality, regiospecificity, and stereospecificity, differ from expectations based on known reactions of these alcohols with SCl2. Selenium dihalides undergo smooth 1,2‐addition to the triple bond of various propargylic alcohols resulting in the formation of the corresponding functionalized divinyl selenides in high yields and with complete regio‐ and stereospecificity. Of special mechanistic interest is thesyn‐addition and anti‐Markovnikov orientation observed in all cases. Copyright © 2010 John Wiley & Sons, Ltd.
Smelting Reduction of Iron Ore‐Coal Composite Pellets
Authors: Sah R. , Dutta S. K. 
Published: June 2010

AbstractSmelting reduction of iron ore‐coal composite pellets has been carried out in an induction furnace. The pellets, tied with tungsten wire, were immersed into the liquid metal bath. The experiments were carried out in the temperature range of 1713 K to 1733 K. For 16‐18 mm diameter pellets, it was observed that (i) the time required for complete dissolution in liquid metal bath is 83‐90 seconds, (ii) the fraction of reduction for 40 seconds of immersion varied from 0.68‐0.87 for Jharia coal pellets and 0.73‐0.92 for Bhilai coal pellets, and (iii) the fraction of reduction increases with decreasing Fe/C ratio and increasing immersion period. X‐ray diffraction (XRD) of reduced pellets showed that the reduction occurred topochemically. Scanning electron microscopic (SEM) examination of partially reduced pellets evinced the structural changes in pellets. The present investigation aims to assess the effect of Fe/C ratio in pellet, volatile matter in coal, and time of pellet immersion into liquid metal bath on reduction of iron ore‐coal composite pellets.
Optimization of Physical Refining to Produce Rice Bran Oil with Light Color and High Oryzanol Content
Authors: Van Hoed Vera , Vila Ayala Jose , Czarnowska Marta , De Greyt Wim , Verhé Roland 
Published: June 2010

AbstractCrude rice bran oil (RBO) is rich in valuable minor components such as tocotrienols, phytosterols and γ‐oryzanol. These compounds are well preserved during physical refining, but in current industrial practice, RBO is mostly refined chemically because this results in a lighter color. However this process removes most of the γ‐oryzanol. The challenge is to develop a refining process which combines a high γ‐oryzanol retention with the commercially desired light color. A modified physical refining process was developed, consisting of an acid degumming, prebleaching, dewaxing, physical removal of free fatty acids using packed column technology, a modified washing step, conventional bleaching and deodorization. A RBO with acceptable oryzanol retention of 39% had a Lovibond red color value (measured with a 5.25‐inch cell) of 2.8, approaching very close the color of a chemically refined RBO (red = 2). At the process step where high (94%) retention of γ‐oryzanol was achieved, a somewhat darker Lovibond red value of 5.2 was obtained.
C18 Unsaturated Fatty Acid Selectivity of Lipases During the Acidolysis Reaction Between Tripalmitin and Oleic, Linoleic, and Linolenic Acids
Authors: Karabulut Ihsan , Durmaz Gokhan , Hayaloglu Ali Adnan 
Published: June 2010

AbstractThe C18 unsaturated fatty acid (UFA) selectivity of three immobilized lipases, namely, Lipozyme TL IM from Thermomyces lanuginosa, Lipozyme RM IM from Rhizomucor miehei, and Novozym 435 from Candida antarctica, was determined in acidolysis conducted in hexane. Tripalmitin with a mixture of equimolar quantities of C18 UFAs was used as the substrate. Significantly different incorporation rates were observed for C18 UFAs used (p < 0.05). The highest incorporation was obtained for all three C18 UFAs with Novozym 435 followed by Lipozyme RM IM and Lipozyme TL IM catalyzed acidolysis under default conditions (substrate mole ratio 1:1; temperature 50 °C; reaction time 6 h; enzyme dosage 10%). Incorporation of the equimolar quantities of C18 UFAs was in the order C18:3 > C18:2 > C18:1 which also reflects C18 UFAs preferences of the lipases. The effects of operating variables on incorporation or UFA selectivity of lipases were also investigated. Among the experimental parameters including the mole ratio of fatty acid to triolein, temperature, enzyme dosage, and time on incorporation, the effect of the substrate mole ratio on UFA selectivity was greater than those of the others.

AbstractBackgroundAdolescent depression has been shown to have a range of adverse outcomes. We used longitudinal data to investigate subsequent higher education in former depressed adolescents.MethodA Swedish population-based investigation of depression in 16–17-year-olds was followed up in national registers 15 years later. Adolescents with depression (n = 361, 78% females) were compared to a group of non-depressed peers of the same age (n = 248, 77% females). The main outcome was graduation from higher education by age 30.ResultsThe adolescent with depression were less likely than their non-depressed peers to have graduated from higher education by age 30, both regarding females (27.7% vs. 36.4%, p < .05) and males (12.7% vs. 28.6%, p < .05). After adjustment for early school performance, socioeconomic status and maternal education, the decreased likelihood of subsequent graduation from higher education remained for depressed males (OR, 0.27; 95% CI, 0.08–0.93) but not for depressed females (OR, 0.93; 95% CI, 0.58–1.49).ConclusionContrary to what previous research has suggested, adolescent depression and its consequences might be particularly destructive to subsequent higher education in males.

AbstractPurposeTo evaluate the impact of the “Spanish Consensus on Physical Health in Patients with Schizophrenia” on psychiatrists’ evaluations of the physical health of patients with schizophrenia.MethodEpidemiological, non-interventional, national, multicentre study, with two retrospective, cross-sectional data collection stages in which 229 psychiatrists evaluated 1193 clinical records of patients with schizophrenia (ICD-10) seen in January and September of 2007.ResultsMean age of the patients was 39.7 ± 11.6 years, 65.5% were men, diagnosed for schizophrenia 14.0 ± 10.3 years ago. Forty percent of the patients suffer from a concomitant disease, the most prevalent being hypercholesterolemia (46.3%), hypertriglyceridaemia (33.5%) and arterial hypertension (26.0%). The difference in the number of patients who had all the physical measurements taken between the two cross-sectional evaluations was 13.8% (CI: 11.8%, 15.7%). The differences for each parameter were: weight 13.7% (CI: 11.7%, 15.6%), BMI 13.58% (CI: 11.6%, 15.5%), waist circumference 14.0% (CI: 12.0%, 15.39%), lipid profile 2.9% (CI: 1.9%, 3.9%) and glycaemia 2.6% (CI: 1.7%, 3.5%).ConclusionsThese results imply that the dissemination of the “Consensus on Physical Health in Schizophrenia Patients”, and possibly other actions, has made psychiatrists more aware of an integral approach to patients with schizophrenia, promoting increased monitoring of the physical health of these patients.
