Contractile activity and reperfusion-induced calcium gain after ischemia in the isolated rat heart. (1988)

Reperfusion of cardiac muscle after an ischemic episode results in the cells becoming overloaded with Ca2+. Gross ultrastructural changes, including the formation of contraction bands, also occur. The present study investigates the relationship, if any, between contractile activity during reperfusion and Ca2+ gain. Contractile activity was inhibited with 2,3-butanedione monoxime (BDM). Isolated perfused rat hearts were subjected to 30 minutes ischemia before reperfusion in the presence or absence of BDM. BDM (10 MIN) significantly reduced the Ca2+ gained during reperfusion. It also enhanced the ATP and creatine phosphate supplies. Ultrastructural examination of cells from hearts reperfused in the presence of BDM for 30 minutes revealed cells with relaxed myofibrils, some glycogen and intact sarcolemmal membranes, compared with cells from hearts reperfused in the absence of BDM which showed contraction bands, sarcolemmal discontinuities and swollen mitochondria. The 'protection' afforded by BDM did not result in a restoration of the cells to their normal state. Removal of BDM and continued reperfusion with Krebs-Henseleit buffer resulted in a gain in Ca2+ and ultrastructural damage, including contraction band formation. These findings suggest a role for contractile activity in the Ca2+ gain. However, preventing the damage which occurs as a result of contractile activity is not sufficient to restore the cells to their preischemic state. This suggests that the damage caused as a result of contractile activity is secondary to some other primary deleterious event.
The method for the reconstruction of complex images of specimens using backscattered electrons (2002)

The backscattered electron signal (BSE) is widely used for investigation of specimen surfaces in a scanning electron microscope (SEM). The development of multiple detector systems for BSE signal detection and the methods of digital processing of these signals have allowed for reconstruction of the third dimension on the basis of the two-dimensional (2-D) SEM image. A technique for simultaneous mapping of material composition (COMPO mode) and reconstruction of surface topography (TOPO mode) has also been proposed. This method is based on the measurements of BSE currents sensed by four semiconductor detectors versus the inclination angle of surface. To improve the separation of topographic and material contrasts in SEM, a correction of the TOPO and COMPO modes (resulting from a theoretical description of the system: electron beam, specimen, and detector) was applied. The proposed method can be used for a correct reconstruction of the surface image when the surface slope is <60 degrees. The measuring limit of the slope was closely connected with the detector setup. Next, the digital simulation of the colors was performed (after application of the method of linearization of BSE characteristic versus atomic number). This procedure to increase the SEM resolution for the BSE signal by use of digital image processing allows for a better distinction between the two elements with high atomic numbers.
DNA adducts from carcinogenic and noncarcinogenic enantiomers of benzo[a]pyrenedihydrodiol epoxide (1989)

The characterization of eight benzo[a]pyrene-deoxyribonucleoside adducts derived from reaction of the anti-dihydrodiol epoxide and deoxyguanylic and deoxyadenylic acids is described. It is reported that the epoxide ring is opened by the purine amino groups to yield similar amounts of both cis and trans products. NMR data show that the 7- and 8-hydroxyl groups are pseudodiaxial in the cis products and pseudodiequatorial in the trans products, and we suggest that these products arise from reaction with the diaxial and diequatorial conformers of the dihydrodiol epoxides, respectively. The chiral nature of the interactions of these metabolites with DNA restricts the range of products formed with this macromolecule, and a trans product with deoxyguanosine is the major product formed with either enantiomer of the anti-dihydrodiol epoxide.
Misidentification of prostamides as prostaglandins (2005)

Prostaglandins and endogenous cannabinoid metabolites share the same lipid backbone with differing polar head groups at exactly the position through which a large molecule is attached to provide antigenicity and thus raise antisera. Hence, we hypothesized that antisera raised against prostaglandins linked to a large molecule such as BSA at the carboxyl functional group would also recognize endogenous cannabinoid metabolites and lead to highly misleading interpretations of data. We found major cross-reactivity of commercial antisera raised to prostaglandins with endocannabinoid metabolites. Furthermore, in a well-characterized cell line (WISH) or primary amnion tissue explants, endocannabinoid treatment led to increased production of endocannabinoid metabolites as opposed to primary prostaglandins. This was apparent only after separation of products by thin-layer chromatography, because they measured as prostaglandins by radioimmunoassay. These findings have major implications for our interpretation of data in situations in which these prostaglandin-like molecules are formed, and they stress the need for chromatographic or spectrometric confirmation of prostaglandin production detected by antibody-based methods.
Insulin resistance and changes in the blood coagulation-fibrinolysis system after a glucose clamp technique in patients with type 2 diabetes mellitus. (2000)

We investigated the relationship between changes in insulin resistance and blood coagulation-fibrinolysis following institution of a glucose clamp (GC) in patients with type 2 diabetes mellitus. We studied 35 type 2 diabetic patients (19 males and 16 females, mean age at 58.3 +/- 11.9 years) and 10 healthy subjects. The hyperinsulinemic euglycemic GC technique was performed using on artificial pancreas. The degree of insulin resistance was determined from the glucose infusion rate (GIR) calculated from the GC technique. The GIR in type 2 diabetic patients was markedly reduced compared to that in healthy subjects. The GIR was significantly and negatively correlated with the body mass index and the serum concentrations of the fasting immunoreactive insulin (FIRI). The plasma concentrations of thrombomodulin (TM) and tissue plasminogen activator (tPA) in the diabetic patients were significantly higher than those in the healthy subjects. The plasma concentrations of plasminogen activator inhibitor 1 in the diabetic patients tended toward higher than those in the healthy subjects. The elevated plasma concentrations of TM and tPA in diabetes were significantly lowered following a GC technique. Patients with advanced nephropathy had significant higher concentrations of TM and tPA compared to healthy subjects. We concluded that diabetic patients have abnormalities in the blood coagulation-fibrinolytic system that can be improved by the GC technique.
Testosterone release rate and duration of action of testosterone pellet implants (2004)

Testosterone pellet implants release testosterone at a steady rate of 1.3 mg/200 mg implant/day (95% CI). The duration of action is about 6 months in an uncomplicated cycle with timing of return shortened by extrusions only in the 3.6% of procedures followed by multiple extrusions. No other patient or procedural features influenced duration of action. Among men with an intact hypothalamo-pituitary unit, plasma gonadotropins are more sensitive than blood total or free testosterone to reduced testosterone delivery following an extrusion.
El derecho al honor a la vista de las últimas Sentencias del Tribunal Supremo (1): estado de la cuestión (2010)

Si hay un concepto altamente subjetivo en todo nuestro ordenamiento juridico es el de honor. Tanto es asi que el propio Tribunal Constitucional ha reconocido la subjetivizacion del mismo, al decir que es un concepto dependiente de las normas, valores e ideas sociales vigentes en cada momento, y esto le hace encajar sin dificultad en la categoria de conceptos juridicos indeterminados.

Fault detection and reconfiguration strategy for ANPC converters (2012)

Active Neutral Point Clamped (ANPC) topology is an optimization of NPC converter and is very attractive in medium-voltage applications. In this paper, a new solution able to detect any type of power semiconductor switch fault inside the ANPC converter is proposed. This strategy allows to achieve fault tolerance of ANPC converter without alteration of the converter architecture, owing to the insertion of three couples of Rogowski coils in the six clamp branches.
Roles of Non-thermal Plasma in Gas-phase Glycerol Dehydration Catalyzed by Supported Silicotungstic Acid (2011)

Acrolein is an indispensable chemical intermediate with a rising demand in recent years. The concern of the increase of propylene prices due to the shrinking supply of nonrenewable crude oil makes the acid-catalyzed gas-phase glycerol dehydration to acrolein a prime candidate for research. Our analysis showed that the sustainable acrolein production from glycerol was both technically and economically viable. Alumina2700® (Al) and Silica1252® (Si) loaded with silicotungstic acid (HSiW) possessed distinct features while provided equally good acrolein yield (73.86mol% and 74.05mol%, respectively) optimally.
Due to the unique non-equilibrium characteristics, non-thermal plasma (NTP) could promote a variety of chemical reactions; however, its application in a dehydration process remained blank. This study used the reaction of glycerol dehydration to acrolein to probe whether NTP could 1) improve acrolein yield during dehydration, 2) suppress the coke formation and regenerate the catalyst, and 3) modify the properties of the catalyst. 
The dielectric barrier discharge configuration was used to generate NTP; various NTP field strengths and also their interaction with temperature and the catalyst were investigated. The results showed that NTP improved the glycerol conversion and that NTP with a proper field strength increased acrolein selectivity. The optimal acrolein yields of 83.6 mol% and 83.1 mol% were achieved with 3.78 kV/cm NTP and 4.58 kV/cm NTP at 275°C for HSiW-Al and HSiW-Si, respectively. 
The application of NTP-O2 (5% oxygen in argon, 4.58 kV/cm) during glycerol dehydration significantly suppressed coke formation on HSiW-Si. NTP-O2 could regenerate the deactivated HSiW-Si at low temperatures by removing both soft and hard coke at various rates. NTP-O2 with higher field strength, at medium operation temperature (150oC) and in argon atmosphere was more effective for coke removal/catalyst regeneration.
Applying NTP to the catalyst fabrication showed some capabilities in modifying catalyst properties, including enlarging surface area, preserving mesopores, increasing acid strength and Bronsted acidity. NTP with argon as the discharge gas performed better in these modifications than NTP with air as the discharge gas.
High performance multi-channel data compression chip (2002)

This paper describes the architecture and implementation of the Data Compression Chip (DCC) for high-performance lossless data compression for multi-channel highspeed data networking applications. The DCC implements an improved adaptive string matching algorithm using a new parallel architecture-the Variable Length String Matcher (VLSM). The VLSM quickly performs an otherwise time-intensive string-matching procedure. Furthermore, by avoiding the typical data structures that require very large and fast memory to store a compression vocabulary, the DCC's VLSM minimizes system costs. By maintaining separate vocabularies for multiple channels, the DCC eliminates the loss of compression efficiency otherwise experienced in typical frame-multiplexed or reset-at-frame applications. The DCC uses a high-performance algorithm with a custom parallel architecture to minimize vocabulary memory (VRAM) requirements and provide very high throughput and compression efficiency for multiple channels. The device has been realized in 0.8 micron CMOS technology with a die area of 9.27 mm/spl times/10.0 mm and power dissipation about 1 W at 20 MHz. It employs a 160 pin PQFP package.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Chronic pain in primary care (1999)

Chronic pain is a very common cause of suffering, disability and economic adversity in the community. It is a complex problem that needs to be understood in a multi-dimensional way for effective management. Most research to date has been based in specialist clinics rather than in primary care, with consequently limited findings. Chronic pain differs from acute pain in that management follows a rehabilitative rather than a treatment model, though these are not mutually exclusive. Full assessment of the patient, preferably multi-disciplinary, will improve his or her outlook. Management should be holistic, rigorous in the application of conventional therapies (including analgesics and physical therapy) and ready to admit an improved understanding of psychological and social techniques. There may be a role for complementary therapies. As a large proportion of chronic pain presents only in the community, there may be a role for greater primary care input to management.
Electronic states and transport in amorphous and liquid transition metals; Fe, Co and Ni (1979)

The d electronic state in the realistic structurally relaxed models of amorphous and liquid transition metals is investigated by using the recursion method. The local density of states is discussed extensively with relation to the local atomic environment. It is found that the density of states for the amorphous case has a double-peaked structure, whereas that for the liquid case is single-peaked. The electronic transport is discussed in a model after Mott (1972) involving s-d transitions and with different mean free paths for s and d electrons. The numerical results of the resistivity and thermoelectric power show quite excellent agreement with experimental ones.

Fluctuations of a plasma (I) (1961)

We consider a fully ionized plasma. At time t the state of the system is represented by a point X in the phase space of all the particles. We define DsdXdX'...dX(s) as the joint probability that at time t the system will be in (X, dX), at time t' in (X', dX'), etc. A systematic procedure has been developed for calculating any desired moment of Ds as an expansion in the discreteness parameters e, m and 1/n. Spectral densities and autocorrelation functions can thus be obtained without any "Stoßzahlansatz" or Markoffian assumption. A comprehensive treatment of a plasma in thermal equilibrium has been carried out. A large class of non-equilibrium states may exist in a hot plasma for sufficient time to be considered stationary. Fluctuations have been calculated for the class of spatially homogeneous states of an infinite plasma. It is of some interest that thermal equilibrium relationships such as Kirchhoff's radiation law and the fluctuation-dissipation theorem survive. As an application we have calculated the degree of excitation of the collective modes such as plasma waves, ion oscillations, etc. For distribution functions which approach instability as some parameter is varied, the energy for some modes becomes very large and ultimately becomes infinite as instability is approached.
HUMAN FACE RECOGNITION FROM A SINGLE FRONT VIEW (1992)

This paper presents a face recognition system which can identify the unknown identity effectively using the front-view facial features. In front-view facial feature extractions, we can capture the contours of eyes and mouth by the deformable template model because of their analytically describable shapes. However, the shapes of eyebrows, nostrils and face are difficult to model using a deformable template. We extract them by using the active contour model (snake). After the contours of all facial features have been captured, we calculate effective feature values from these extracted contours and construct databases for unknown identities classification. In the database generation phase, 12 models are photographed, and feature vectors are calculated for each portrait. In the identification phase if any one of these 12 persons has his picture taken again, the system can recognize his identity.
Environment-adaptation mobile radio propagation prediction using radial basis function neural networks (1997)

This paper investigates the application of a radial basis function (RBF) neural network to the prediction of field strength based on topographical and morphographical data. The RBF neural network is a two-layer localized receptive field network whose output nodes from a combination of radial activation functions computed by the hidden layer nodes. Appropriate centers and connection weights in the RBF network lead to a network that is capable of forming the best approximation to any continuous nonlinear mapping up to an arbitrary resolution. Such an approximation introduces best nonlinear approximation capability into the prediction model in order to accurately predict propagation loss over an arbitrary environment based on adaptive learning from measurement data. The adaptive learning employs hybrid competitive and recursive least squares algorithms. The unsupervised competitive algorithm adjusts the centers while the recursive least squares (RLS) algorithm estimates the connection weights. Because these two learning rules are both linear, rapid convergence is guaranteed. This hybrid algorithm significantly enhances the real-time or adaptive capability of the RBF-based prediction model. The applications to Okumura's (1968) data are included to demonstrate the effectiveness of the RBF neural network approach.
Carbon Dots as Nontoxic and High-Performance Fluorescence Imaging Agents (2009)

Fluorescent carbon dots (small carbon nanoparticles with the surface passivated by oligomeric PEG molecules) were evaluated for their cytotoxicity and in vivo toxicity and also for their optical imaging performance in reference to that of the commercially supplied CdSe/ZnS quantum dots. The results suggested that the carbon dots were biocompatible, and their performance as fluorescence imaging agents was competitive. The implication to the use of carbon dots for in vitro and in vivo applications is discussed.

Microwave hyperthermia in the treatment of spontaneous canine tumours: an analysis of treatment parameters and tumour response (1988)

Fifty-one spontaneous canine tumours were treated with combined radiation and hyperthermia in a pilot study designed to investigate the feasibility and efficacy of the combined modality treatment in the dog. The tumours varied in site and histological type: 35 were in the oral cavity and included squamous cell carcinoma, melanoma and various 'sarcomas'. All animals received radiation (36-40 Gy in four weekly fractions) and post-irradiation hyperthermia (prescription -44 degrees C for 30 min) on one or two occasions. The microwave hyperthermia system was technically satisfactory in elevating tumour temperature to 44 degrees C or above in 95 per cent of treatments. However, thermal gradients of the order of 3-5 degrees C were frequently measured across the tumour, and rarely did all peripheral points achieve the target of 44 degrees C for 30 min. The overall tumour response rate (CR + PR) was 87.7 per cent with 60.7 per cent of tumours achieving complete regression. Smaller lesions showed a significantly greater response rate (P = 0.004) and those lesions which received two thermal treatments show an increased response (P = 0.0095). Fifty-one per cent of tumours showed significant necrosis following hyperthermia. Normal tissue necrosis was seen in three patients; in two cases this was attributed to hyperthermia. Local tumour control rate and necrosis was not correlated with measured minimum, mean or maximum thermal doses.
Plant genome sequencing: applications for crop improvement (2009)

DNA sequencing technology is undergoing a revolution with the commercialization of second generation technologies capable of sequencing thousands of millions of nucleotide bases in each run. The data explosion resulting from this technology is likely to continue to increase with the further development of second generation sequencing and the introduction of third generation single-molecule sequencing methods over the coming years. The question is no longer whether we can sequence crop genomes which are often large and complex, but how soon can we sequence them? Even cereal genomes such as wheat and barley which were once considered intractable are coming under the spotlight of the new sequencing technologies and an array of new projects and approaches are being established. The increasing availability of DNA sequence information enables the discovery of genes and molecular markers associated with diverse agronomic traits creating new opportunities for crop improvement. However, the challenge remains to convert this mass of data into knowledge that can be applied in crop breeding programs.
