Antioxidant and antimicrobial activities of Bauhinia racemosa L. stem bark (2005)

The present study was carried out to evaluate the antioxidant and antimicrobial activities of a methanol extract of Bauhinia racemosa (MEBR) (Caesalpiniaceae) stem bark in various systems. 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) radical, superoxide anion radical, nitric oxide radical, and hydroxyl radical scavenging assays were carried out to evaluate the antioxidant potential of the extract. The antioxidant activity of the methanol extract increased in a concentration-dependent manner. About 50, 100, 250, and 500 microg MEBR inhibited the peroxidation of a linoleic acid emulsion by 62.43, 67.21, 71.04, and 76.83%, respectively. Similarly, the effect of MEBR on reducing power increased in a concentration-dependent manner. In DPPH radical scavenging assays the IC50 value of the extract was 152.29 microg/ml. MEBR inhibited the nitric oxide radicals generated from sodium nitroprusside with an IC50 of 78.34 microg/ml, as opposed to 20.4 microg/ml for curcumin. Moreover, MEBR scavenged the superoxide generated by the PMS/NADH-NBT system. MEBR also inhibited the hydroxyl radical generated by Fenton's reaction, with an IC50 value of more than 1000 microg/ml, as compared to 5 microg/ml for catechin. The amounts of total phenolic compounds were also determined and 64.7 microg pyrocatechol phenol equivalents were detected in MEBR (1 mg). The antimicrobial activities of MEBR were determined by disc diffusion with five Gram-positive, four Gram-negative and four fungal species. MEBR showed broad-spectrum antimicrobial activity against all tested microorganisms. The results obtained in the present study indicate that MEBR can be a potential source of natural antioxidant and antimicrobial agents.
Intelligent agents for wireless sensor networks (2005)

Interpolation is a technique used to estimate the value of a function at a given location, assuming that the values of the function are known for surrounding locations. A Wireless Sensor Network (WSN) is a spatially distributed set of sensor platforms usually with a range of sensory modalities e.g. temperature or light intensity. Interpolation can be used to intelligently activate nodes of a WSN for power conservation. In this paper we argue that this can form the basis for a distributed agent-based power management scheme and we propose an algorithm for achieving this. As a corollary to this approach we will also demonstrate the feasibility of using distributed, intelligent agents on computationally challenged devices such as the sensor nodes.

Comparison of Bone Marrow and Hematologic Findings in Patients with Human Immunodeficiency Virus Infection and Those with Myelody splastic Syndromes and Infectious Diseases (1994)

The histologic, hematologic, and morphometric findings of 40 patients positive for the human immunodeficiency virus (HIV) were compared statistically with those of 40 patients with primary myelodysplastic syndromes (MDS) and those of 32 HIV-negative patients with infectious diseases. The severity of anemia and the abnormalities of erythropoiesis in the group of HIV patients were less pronounced than in the group with MDS; megakaryopoiesis showed similarities only with the group of patients with infectious diseases, and characteristics of dysplasia were not observed. Granulopoiesis in MDS showed an increase of blasts in several cases; this was not found in any biopsy specimen from the HIV group. In addition, a statistically significant increase of monocyte-like cells and giant bands could be observed in the bone marrow of the HIV patients. The peripheral blood findings and bone marrow picture in the series of our HIV patients appeared to be related mainly to the influence of opportunistic infections, although a direct effect of the HIV itself could not be excluded.
The Moldovan Social Investment Fund : Building Local Capacity and Improving Services (2002)

The note reviews the impact of the Moldova Social Investment Fund (MSIF), aimed at building local capacity, and improving services, though also looks at the implementation problems connected with community participation. To address these issues the MSIF management delegated responsibilities to implementing agencies, while also improved technical assistance. The development of partnerships achieved greater impact, which led to performance contracts, as tools to promote the sustainability of investments. Lessons reinforce the need for community ownership, and, suggest wider community consultation to identify, and solve technical issues. The need to maintain links with communities after subproject implementation is emphasized, to ensure long-term sustainability.

Noonan‐like syndrome with loose anagen hair: A new syndrome? (2003)

We present three children with short stature, the same facial phenotype, macrocephaly, enlarged cerebral spinal fluid spaces, short neck with redundant skin, severe GH deficiency, mild psychomotor delay with attention deficit/hyperactivity disorder (ADHD), mild dilatation of the pulmonary root in two of them, and a unique combination of ectodermal abnormalities. Their appearance, not completely typical of Noonan syndrome, the behavioral phenotype, GH deficiency, darkly pigmented and hairless skin, and the unusual aspect of the hair, defined as loose anagen hair syndrome did not fit any known condition. We postulate that these children may represent a distinct, previously unreported syndrome that we would name "Noonan-like syndrome with loose anagen hair".

An efficient shape analysis method for shrimp quality evaluation (2012)

Two grading criteria used in determining shrimp product quality and value by the shrimp industry are: 1. Presence or percentage of black spot, measured as a percentage of the total body surface. 2. Shape quality referring to whole shrimp and broken pieces. Black spots (melanoma) on the shrimp surface are evidence of aging shrimp and are considered defects that must be removed from the main production line. Shape quality is measured as the size and the completeness of the body. Broken shrimp pieces are considered a product defect and also must be removed from the main production line. Black spot detection is a simple task for a well-designed machine vision system, which provides consistent and controlled lighting. Shape analysis, on the other hand, is a challenging task because it involves contour extraction and shape analysis. In this paper, a simple, fast, and accurate shape analysis method using Turn Angle Cross-correlation is developed for shrimp quality evaluation. Our analysis results validate that the performance of the proposed shape analysis method is suitable for real-time inspection for commercial applications.
Sobre la uniformidad de las tarifas óptimas (1981)

El propósito del trabajo es extender el análisis tradicional de la tarifa óptima. La primera sección presenta el estudio tradicional Marshalliano sobre tarifas óptimas que Johnson realizara en los años 1950. La segunda sección extiende el análisis anterior a un mundo de “n” bienes comerciados incluyendo impuestos y subsidios a las exportaciones e importaciones. La tercera sección estudia el caso en que el país doméstico posee el poder de influir solamente los precios internacionales de un subconjunto de bienes. Se muestra que una condición necesaria para que una estructura arancelaria sea óptima es que la tarifa sobre los bienes comerciados en las cuales el país doméstico es tomador de precios sea uniforme, y esto es independiente del hecho de que el bien comerciado sea importado o exportado. La sección cuarta ejemplifica el análisis anterior reduciendo los “n” sectores comerciados a solo tres que relacionamos con el caso argentino. Clasificación JEL: F13
Progression of liver cirrhosis to HCC: an application of hidden Markov model (2011)

The hidden Markov model allowing for misclassification is well suited to analyses of health service databases, since it is able to capture bias due to the fact that the quality and accuracy of the available information are not always optimal. The probability of evolution of a cirrhotic subject to HCC depends on sex and age class, while hepatitis C virus infection and comorbidities correlated with alcohol abuse do not seem to have an influence.
News review 2008 (2008)

After the problems with the 2007 appointment round for junior doctors, 2008 was a much quieter year after the centralised computer application process was abandoned.

The Tooke inquiry report, Aspiring to Excellence , published in January, proposed ringfencing the budget for medical education and training and creating a new body called NHS: Medical Education England (NHS: MEE) to oversee training in England. This proposal was agreed by the Department of Health, and the new body should start work in January 2009. MEE will be an independent advisory body that should give a coherent, professional voice on medical education and training and advise the Department of Health.

Professor Tooke also proposed the merger of the General Medical Council and Postgraduate Medical Education Training Board, which should happen in 2010.

In February, the Home Office made changes to the immigration system that meant far fewer medical graduates who gained their degrees outside the European Economic Area were eligible for posts in the NHS.

And although the number of posts available for those training to work in a hospital setting is still under review, the Department of Health announced in September that the intake to year 1 of GP specialty training programmes would increase by 400 in the 2009-10 allocations.

As Newshound reported in August, there were none of the problems encountered the previous year with junior doctors scrabbling around to find a post. The BMA said that although there were still some uncertainties around the start of the placements, most juniors did get jobs.

We give lower bounds on the state complexity of geometric Goppa codes. For Hermitian codes we calculate the DLP bound, /spl nabla/, and determine when /spl nabla/ is tight and when it is not.
Geological evolution of the trachytic caldera volcano Menengai, Kenya Rift Valley (1984)

Menengai is a trachytic central volcano underlain by a high-level magma chamber. Activity started shortly before 0.18 Ma, with the growth of a low-angle trachyte lava shield having a volume of about 30 km³. Krakatau-style collapse to form a 77 km² caldera within an embayed ring-fracture was accompanied by the eruption of two ash-flow tuffs representing a combined magma volume of about 50 km³. The eruption of both tuffs was preceded by an air-fall phase. Both were emplaced as single flow units, and have intermediate aspect ratios of c. 1:4000. The tuffs cover an area of c. 1350 km², including outcrops higher than the eruptive vents. During post-caldera times, some 25 km³ of magma was erupted, mostly as lava flows which now cover the caldera floor, but also as cinder cones and plinian-type tephra sheets. The chronology of syn- and post-caldera events is based on correlation with dated fluctuations in the levels of nearby lakes, suggesting that the two ash-flows may have been erupted at about 29 000 and before 12 850 years ago. Lake sediments inside the caldera provide evidence for a late intra-caldera lake from about 10 300 to 8300 years B.P.
Simplified Viterbi processors for the GSM Pan-European cellular communication system (1994)

The GSM cellular system provides the European countries with a common digital mobile radio structure for overland communications. This paper illustrates an implementation of a GSM receiver in which two reduced complexity Viterbi processors are used: the first one for the demodulation of the GMSK signal and the second one for the decoding operations. The performance of the receiver is evaluated through a channel simulator for mobile communications. The results show that in many cases the proposed receiver allows the significant reduction of the computation complexity with respect to the classical Viterbi processor. In particular, for mean and high signal-to-noise ratios, a reduction of four times in the computational burden is obtained.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A quantitative assay for the non-covalent association between apolipoprotein[a] and apolipoprotein B: an alternative measure of Lp[a] assembly (2000)

Increasing evidence suggests that the assembly of lipoprotein[a] (Lp[a]) proceeds in two steps. In the first step, non-covalent interactions between apolipoprotein[a] (apo[a]) and apolipoprotein B (apoB) of low density lipoprotein (LDL) form a dissociable apo[a]:LDL complex. In the second step, a covalent disulfide linkage forms the stable Lp[a] particle. Several methods are currently used to study the assembly of Lp[a], however, these methods are laborious, time-consuming, and not suitable for a high throughput screening. We report here the development of a rapid and simple assay based on the binding of labeled LDL to a Lp[a]/apo[a] substrate which is immobilized on the surface of a microtiter plate. Quantification of bound LDL provides a measure of the extent of complex formation. Labeled LDL bound to both Lp[a] and apo[a] substrates with similar affinity. Plasma lipoproteins containing apoB as well as free apo[a] were capable of competing with LDL binding. The binding of LDL to Lp[a]/apo[a] was inhibited by L-proline and lysine analogs, which are known to inhibit the non-covalent association between apo[a] and apoB. Using this method we have found that nicotinic acid and captopril are able to inhibit the association of apo[a] with apoB. This method is compatible with automation and can be applied to a high throughput screening of inhibitors of Lp[a] formation.
Endothelial and inducible nitric oxide synthase gene and protein expression in hyperoxia-induced lung injury in premature rat (2002)

AIM: In a preterm rat model of hyperoxia-induced lung injury, we studied the effect of prolonged (7 d) hyperoxia on endothelial nitric oxide synthase (eNOS) and inducible nitric oxide synthase (iNOS) expression in the lungs. METHODS: Preterm rats were delivered by hysterotomy at 21 d gestation and randomly divided into hyperoxia group and room-air control and continuous exposure to oxygen (oxygen >0.95) or room air during 7 d. The animals were sacrificed on d 7 of life with an overdose of intraperitoneal pentobarbital. The mRNA levels of the eNOS, iNOS were measured by reverse-transcription polymerase chain reaction (RT-PCR). eNOS and iNOS protein expression measured by Western blotting. In addition, lung wet/dry weight ratio, the protein and cellular content of bronchoalveolar lavage fluid (BALF) were performed. RESULTS: Compared to the room-air control, hyperoxia group developed severe lung damage. There were a significant increase in lung wet/dry weight ratio (5.57±0.29 vs 5.29±0.25, t=2.29, P<0.05) and the protein content (1.49 g/L vs 0.32 g/L, t=28, P<0.05) and cell count (139.70×10 7 /L vs 16.30×10 7 /L, t=21, P<0.05) in BAL. eNOS mRNA expression in the hyperoxia group were significantly elevated (1.02±0.06 vs 0.70±0.12, t=6.36, P<0.01). The mean iNOS mRNA expression also showed an increase in the hyperoxia group, although the difference was not statistically significant. This was associated with significantly higher pulmonary eNOS, iNOS protein expression (8.8±0.8 vs 4.5±1.0, t=8.14, P<0.01 and 4.6±0.6 vs 3.2±0.6, t=3.21, P<0.05) in the hyperoxia group. CONCLUSION: Hyperoxic exposure of preterm rat pups causes upregulation of NOS gene expression, which persists even in established oxygen-induced lung damage. Endogenous NOS may play an important role in the pathphysiology of pulmonary oxygen injury in premature animal.
Cell‐Cycle Arrest at G2/M and Growth Inhibition by Apigenin in Human Colon Carcinoma Cell Lines (2000)

Apigenin, a common dietary flavonoid, has been shown to induce cell cycle arrest in both epidermal and fibroblast cells and inhibit skin tumorigenesis in murine models. The present study assessed the influence of apigenin on cell growth and the cell cycle in the human colon carcinoma cell lines SW480, HT-29, and Caco-2. Treatment of each cell line with apigenin (0–80 μM) resulted in a dose-dependent reduction in both cell number and cellular protein content, compared with untreated control cultures. DNA flow cytometric analysis indicated that treatment with apigenin resulted in G2/M arrest in all three cell lines in a time- and dose-dependent manner. Apigenin treatment (80 μM) for 48 h produced maximum G2/M arrest of 64%, 42%, and 26% in SW480 cells, HT-29 cells, and Caco-2 cells, respectively, in comparison with control cells (15%). The proportion of S-phase cells was not altered by apigenin treatment in each of the three cell lines. The G2/M arrest was reversible after 48 h of apigenin treatment in the most sensitive cell line SW480. The degree of G2/M arrest by apigenin was inversely correlated with the corresponding inhibition of cell growth measurements in all three cell lines (r = −0.626 to −0.917, P≤0.005). Moreover, an immune complex kinase assay demonstrated an inhibition of p34cdc2 kinase activity, a critical enzyme in G2/M transition, in each cell line after treatment with apigenin (50–80 μM). Western blot analyses indicated that both p34cdc2 and cyclin B1 proteins were also decreased after apigenin treatment. These results indicate that apigenin inhibits colon carcinoma cell growth by inducing a reversible G2/M arrest and that this arrest is associated, at least in part, with inhibited activity of p34cdc2 kinase and reduced accumulation of p34cdc2 and cyclin B1 proteins. Differences in induction of G2/M arrest by apigenin in the three colon carcinoma cell lines suggest that dietary apigenin may be differentially effective against tumors with specific mutational spectra.

Direct Synthesis of Branched Gold Nanocrystals and Their Transformation into Spherical Nanoparticles (2006)

We report a facile synthesis of branched gold nanocrystals by the addition of a suitable amount of NaOH to an aqueous solution of cetyltrimethylammonium bromide (CTAB), HAuCl(4), and ascorbic acid. The branched nanocrystals were formed within minutes of reaction and showed monopod, bipod, tripod, and tetrapod structures. They are crystalline and have smooth surfaces. These gold multipods are kinetically controlled products and are thermodynamically unstable. The branched nanocrystals quickly transformed into spherical nanoparticles within 1 h of reaction, and the process was essentially complete after 2 days. The morphological transformation has been monitored by both UV-vis absorption spectroscopy and electron microscopy. The appearance of two major absorption bands for the branched gold nanocrystals eventually became only a single band at 529 nm for the spherical nanoparticles. The resulting nanoparticles are single crystals with diameters of 20-50 nm and do not show a faceted structure. When the freshly prepared branched nanocrystals are kept in a refrigerator at 4 degrees C, their multipod structure can be preserved for over a month without significant spectral shifts.
Kinematic identification of a closed-chain manipulator using a laser interferometry based sensing technique (2004)

This paper focuses on a technique for the identification of parameters needed for kinematic modeling of an industrial manipulator, Motoman SK 120, with a parallel five-bar mechanism. Two classical estimation techniques, nonlinear and linear least squares, are employed to determine the parameters from a number of manipulator end point positions measured by a high precision laser tracking system with a single beam laser interferometer. The kinematics parameters of the five-bar mechanism in the topology of the manipulator are considered during kinematic modeling and parameter identification procedure. Numerical results presented demonstrate that the root mean square position error can be improved by at least 60% with the identified parameters. Although slightly different parameters are obtained from both estimation techniques, the resulting root mean square position errors remain the same. When the kinematics parameters of the five-bar mechanism are not included in the model for parameter estimation, the improvement in the root mean square position errors has been limited to 35%.

Electric field and energy computation on wet insulating surfaces (1996)

The paper presents the results of electric field and energy computation on insulating surfaces covered by water in the form ranging from small discrete droplets to large wet patches. The goal of this study was to understand the differences in the flash-over performance of outdoor insulators, in particular nonceramic insulators, under contaminated conditions as a function of surface wettability. The computational algorithm is based on the charge simulation method. A decrease in the maximum electric field at the water droplet tip is obtained as the droplet size increases, however, the electrostatic potential energy increases with the size of the water droplet, which might increase the surface discharge intensity. The role of the coalescence of small water droplets into larger droplets and filaments on the electric field and energy has been investigated. The location of such larger water bodies with respect to the electrodes has been examined. These computations shed some light not only on the role of hydrophobic surfaces but also on the location of hydrophobic surfaces along the insulator on the flashover performance of outdoor insulators. It has been shown that these computations provide quantitative data that compliments information obtained from simpler techniques such as visual observation and surface resistance measurements, for the purpose of assessing the performance of insulators in service.
