    Full Text Available Introdução: O aumento crescente da população em hemodiálise tem implicado o recurso a acessos vasculares de maior complexidade técnica. A introdução de modificações na técnica cirúrgica da transposição da veia basílica (TVB) pretende agilizar o procedimento e diminuir a sua morbilidade. Métodos: Aná [...] lise prospectiva das TVB efectuadas no CHP-HSA entre Setembro de 2005 e Setembro de 2009. Resultados: Efectuaram-se 74 TVB em 74 doentes, os quais tinham, em média, 2 acessos autólogos prévios. A TVB foi o primeiro acesso em 20,3% dos doentes. O intervalo médio de seguimento foi de 14,5 meses. Ocorreram 2 falências nos primeiros 30 dias. A taxa de patência secundária aos 3, 12 e 24 meses foi de 95,7%, 85,1% e 62,2%, respectivamente. A Diabetes associou-se a pior taxa de patência (p=0,018). A taxa de complicações perioperatórias foi de 28,4%, sendo a infecção a mais frequente (n=6, 8,1% do total de TVB). A trombose foi a principal causa de falência, tendo ocorrido em 24,3% de todas as TVB. Conclusões: Reconhece-se a superioridade do acesso autólogo, como a melhor opção de acesso vascular para hemodiálise. A TVB é subutilizada, devido às exigências técnicas e necessidades logísticas. Melhoramos a técnica cirúrgica e de tunelização, ao reduzir o tamanho das incisões e o tempo cirúrgico. Os nossos resultados revelaram uma boa patência a longo prazo, pelo que consideramos que deve ser mais utilizada. Abstract in english Introduction: The expanding haemodialysis population has lead to increased requirement for more complex vascular accesses. Modifications introduced in basilic vein transposition technique are intended to streamline the procedure and reduce its morbidity. Methods: All patients who underwent BVT from [...] September 2005 to September 2009 in CHP-HSA were prospectively reviewed. Results: Seventy-four BVT were performed in 74 patients. Patients had a mean of 2.0 previous access attempts. BVT was the first access in 20.3% of the patients. Median follow-up was 14.5 months. There were two primary failures. Secondary patency rates were 95.7%, 85.1% and 62.2% at 3, 12 and 24 months, respectively. Diabetes was associated with poor patency. Perioperative complication rate was 28.4%, with infection being the most frequent (n=6, 8.1% of all TVB). Thrombosis was the main cause of failure, occurring in 24.3% of all TVB. Conclusion: Autologous access superiority is well established. BVT is an underused technique due to its surgical expertise needs and logistic demands. We improved the surgical technique and the tunneling technique, reducing the size of the incisions and the time of operation. Our results showed a good secondary patency rate and, in the authors view, this technique should be more widely used.

    Reconstruction of an arteriovenous fistula (AVF) after an initial failure to provide long-term patency has been desired in the era when hemodialysis patients' prognosis is improving. The forearm basilic vein AVF should be considered, before an artificial graft shunt or an AVF in the cubital region. The present study was designed to establish a strategy for the creation and maintenance of AVFs using the forearm basilic vein. This study reviewed 76 cases of reconstructed AVF including 18 cases using the basilic vein (23.7% of total cases). The following four points were considered: arm positioning of the cubital flexion position combined with the forearm supinated position; several small skin incisions with a subcutaneous tunnel; sufficient venous dilatation using Fogarty balloon catheter; and early percutaneous angioplasty introduction for immature AVF. The primary and secondary patency rates were examined. A radiobasilic AVF was created through a subcutaneous tunnel in two cases. The primary and secondary patency rates of AVF with the basilic vein were 54.7% and 76.7% respectively, whereas those of AVF with the cephalic vein were 49.3% and 71.3%. The basilic was not inferior to the cephalic vein (P-value of the log-rank test for primary and secondary patency rates were 0.927 and 0.811, respectively). Early stage percutaneous angioplasty was effective in five cases with immature AVF. The forearm basilic vein was useful in AVF reconstruction and equivalent to radiocephalic reconstruction. Careful observation and percutaneous angioplasty during the early period after the surgery were essential for long-term patency. PMID:24107279

Su anatomía se ha descrito en parte, porque los datos relativos a su patrón de ramificación y distancias a puntos de referencia adyacentes son insuficientes. El propósito de este estu [...] dio fue proporcionar datos morfométricos sobre la anatomía del NCAM, comparando entre lados y sexos. Se disecaron 96 miembros superiores de 26 hombres y 22 mujeres. Se encontró que 5 ramos del NCAM traspasaron la fascia profunda y llegaron 4 hasta la línea interepicondilar (LIE). Presencia de 2 y 3 ramos se encontró en la mayoría de los casos (>80%). Las distancias de estos ramos a los puntos anatómicos variaron considerablemente. En caso de ausencia de ramos, la distancia medial al epicóndilo medial (EM) y arteria braquial (AB) fueron de aproximadamente 1,5 cm, mientras que a la vena basílica (VB) fueron 0,7 cm en ambos sexos. Independientemente del patrón de ramificación, el NCAM podría pasar sobre o cerca (a menos de 0,5 cm ) del EM, VB y AB. Asimetría en el patrón de ramificación se encontró en 50% de las muestras. Diferencias en algunos de los parámetros de medición se observaron según sexo, pero no por lado. Estos datos son relevantes para localizar el NCAM durante el bloqueo del nervio y la toma de injertos, sino también para evitar la lesión del nervio durante los procedimientos quirúrgicos. Abstract in english Medial antebrachial cutaneous nerve (MACN) courses in the medial arm to provide sensory innervation to the medial forearm. Its anatomy has been partly described since data regarding its branching pattern and distances to adjacent landmarks are still lacking. The purpose of this study was to provide [...] morphometric anatomy of the MACN with comparisons between sides and sexes. Ninety-six upper extremities from 26 males and 22 females were dissected. We found that up to 5 branches of MACN pierced the deep fascia with the maximum of 4 reaching the interepicondylar line (IEL). Presence of 2 and 3 branches was found in the majority of cases (> 80%). The distances from these branches to the landmarks varied considerably. In case of no branch, the mean distances to the medial epicondyle (ME) and brachial artery (BA) were approximately 1.5 cm while those to the basilic vein (BV) were 0.7 cm in both sexes. Regardless of the branching pattern, the MACN could pass over or close (within 0.5 cm) to the ME, BV and BA. Asymmetry in the branching pattern was found in 50% of specimens. Sex but not side differences were observed in some measurement parameters. These data are crucial for not only localizing the MACN during nerve block and graft harvest but also avoiding the nerve injury during surgical procedures.

    Full Text Available The study aims at assessing Basil’s genetic phenotypic variability and viral disease incidence in Nigeria for sustainable pathological interventions. Basil (Ocimum basilicum is important for it’s medicinal and nutritive value. It is highly adaptable as a potential crop in the tropics and could therefore enhance the food security of sub Saharan Africa nations. Germplasm seed evaluation and characterization was therefore carried out from the nationwide National Horticultural Research Institute (NIHORT seed collection survey to expand NIHORT basil genetic base. The field layout was completely randomized design with five replications. The treatments were: O. basilicum, O. gratissimum and the local basil. Treatments were randomly allocated per replication. There were significant phenotypic differences in the O. basilicum variety. These differences were observed in the plant coloration ranging from deep to light purple coloration of stem, leaf, leaf vein and petiole. Our observations also revealed for the first time significant tolerance to Venial Mottle Mosaic Virus (VMMV in the purple colored compared to the green O. basilicum in the early stages of growth till 50% anthesis. This is the first report of this observation in the African continent. Tolerance to VMMV symptoms increased significantly (LSD 5% with purplish coloration. We concluded that inducement of purplish coloration in Basil through breeding might improve tolerance to VMMV and thereby increase market value of Basil with sustainable pathological interventions.

    Transposition of the great artery is one of common congenital cardiac disease resulting cyanosis. Death occurs easily in untreated patients with transposition and intact ventricular septal defect (VSD) in infancy at a few days of age when posterior descending coronary artery (PDA) closed. Since there are 2 parallel circulations, flow from pulmonary to systemic circulation is necessary for systemic oxygenation, and Balloon atrial septostomy or prostaglandin infusion should be performed especially if patient do not have VSD. Although the advent of fetal echocardiography, it is difficult to diagnose the transposition of the great arteries (TGA) as abnormality of great vessels is relatively undistinguishable. The diagnosis of transposition is in itself an indication for surgery, and arterial switch procedure is performed in the case the left ventricle pressure remains more than 2/3 of systemic pressure. Preoperative diagnosis is important as associated anomalies and coronary artery branching patterns are important to decide the operative indication and timing of surgery. PMID:26197905

    One obstacle to running very large two- and three-dimensional codes on the Cray X-MP and Y-MP systems is to efficiently perform array transpositions using SSD storage. This article discusses how such transpositions can be performed by means of algorithms that feature exclusively unit stride, long vector transfers between main memory and SSD, and which only require a single pass through the data (provided sufficient main memory buffers are available).

Abstract in english It is known that stenosis or central venous obstruction affects 20 to 50% of patients who undergo placement of catheters in central veins.

The alternative surgical treatment chosen was to transpose the RUL cephalic vein, forming a venous necklace at the anterior cervical region, bypassing the site of venous occlusion. In order to achieve this, we dissected the cephalic vein in the right arm to its junction with the axillary vein, devalved the cephalic vein and anastomosed it to the contralateral external jugular vein, providing venous drainage to the RUL, alleviating symptoms of venous hypertension and preserving function of the brachiobasilic fistula.

  12. Sleeping Beauty Transposition.

    Ivics, Zoltán; Izsvák, Zsuzsanna

    2015-04-01

    Sleeping Beauty (SB) is a synthetic transposon that was constructed based on sequences of transpositionally inactive elements isolated from fish genomes. SB is a Tc1/mariner superfamily transposon following a cut-and-paste transpositional reaction, during which the element-encoded transposase interacts with its binding sites in the terminal inverted repeats of the transposon, promotes the assembly of a synaptic complex, catalyzes excision of the element out of its donor site, and integrates the excised transposon into a new location in target DNA. SB transposition is dependent on cellular host factors. Transcriptional control of transposase expression is regulated by the HMG2L1 transcription factor. Synaptic complex assembly is promoted by the HMGB1 protein and regulated by chromatin structure. SB transposition is highly dependent on the nonhomologous end joining (NHEJ) pathway of double-strand DNA break repair that generates a transposon footprint at the excision site. Through its association with the Miz-1 transcription factor, the SB transposase downregulates cyclin D1 expression that results in a slowdown of the cell-cycle in the G1 phase, where NHEJ is preferentially active. Transposon integration occurs at TA dinucleotides in the target DNA, which are duplicated at the flanks of the integrated transposon. SB shows a random genome-wide insertion profile in mammalian cells when launched from episomal vectors and "local hopping" when launched from chromosomal donor sites. Some of the excised transposons undergo a self-destructive autointegration reaction, which can partially explain why longer elements transpose less efficiently. SB became an important molecular tool for transgenesis, insertional mutagenesis, and gene therapy. PMID:26104705

    In comparative genomics, a transposition is an operation that exchanges two consecutive sequences of genes in a genome. The transposition distance, that is, the minimum number of transpositions needed to transform a genome into another, is, according to numerous studies, a relevant evolutionary distance. The problem of computing this distance when genomes are represented by permutations, called the Sorting by Transpositions problem, has been introduced by Bafna and Pevzner in 1995. It has naturally been the focus of a number of studies, but the computational complexity of this problem has remained undetermined for 15 years. In this paper, we answer this long-standing open question by proving that the Sorting by Transpositions problem is NP-hard. As a corollary of our result, we also prove that the following problem is NP-hard: given a permutation pi, is it possible to sort pi using db(pi)/3 permutations, where db(pi) is the number of breakpoints of pi?

  5. Corrected transposition of great arteries

    International Nuclear Information System (INIS)

    20 patients with the diagnosis of congenital corrected transposition of great arteries were analyzed. The diagnosis was based on routine clinical examination, echocardiography and in certain cases on heart catheterization and angiocardiography. In the most cases c-TGA coexists with additional heart defects. The commonest coexisting defects were: ventricular septal defect (60%), pulmonary stenosis (50%), atrio-ventricular valve regurgitation, predominantly systemic (tricuspid 45%). In the most cases 2D Doppler echo examination was sufficient for morphological assessment. In order to quality to cardiosurgical treatment heart catheterization and angiocardiography were necessary. 5 children were treated surgically. 3 of them underwent palliative procedures, one - Rastelli procedure and one had corrective surgery with bad result. Clinical picture of corrected transposition of great arteries is determined by coexisting additional heart defects. (author)

    Water, ethanol and acetone extracts from leaves and flowers of purple basil, one of the most popular spices consumed in the Thrace region of Turkey, were tested in vitro for their ability to inhibit peroxidation of lipids, to scavenge DPPH, hydrogen peroxide, superoxide anion, to reduce Fe(III) to Fe(II) and to chelate Fe(II) ions. The results showed that purple basil contained naturally occurring antioxidant components and possessed antioxidant activity which may be attributed to its lipid peroxidation inhibitory, radical scavenging and metal chelating activities. It was concluded that purple basil might be a potential source of antioxidants.

    Full Text Available Abstract Transposition of the great arteries (TGA, also referred to as complete transposition, is a congenital cardiac malformation characterised by atrioventricular concordance and ventriculoarterial (VA discordance. The incidence is estimated at 1 in 3,500–5,000 live births, with a male-to-female ratio 1.5 to 3.2:1. In 50% of cases, the VA discordance is an isolated finding. In 10% of cases, TGA is associated with noncardiac malformations. The association with other cardiac malformations such as ventricular septal defect (VSD and left ventricular outflow tract obstruction is frequent and dictates timing and clinical presentation, which consists of cyanosis with or without congestive heart failure. The onset and severity depend on anatomical and functional variants that influence the degree of mixing between the two circulations. If no obstructive lesions are present and there is a large VSD, cyanosis may go undetected and only be perceived during episodes of crying or agitation. In these cases, signs of congestive heart failure prevail. The exact aetiology remains unknown. Some associated risk factors (gestational diabetes mellitus, maternal exposure to rodenticides and herbicides, maternal use of antiepileptic drugs have been postulated. Mutations in growth differentiation factor-1 gene, the thyroid hormone receptor-associated protein-2 gene and the gene encoding the cryptic protein have been shown implicated in discordant VA connections, but they explain only a small minority of TGA cases. The diagnosis is confirmed by echocardiography, which also provides the morphological details required for future surgical management. Prenatal diagnosis by foetal echocardiography is possible and desirable, as it may improve the early neonatal management and reduce morbidity and mortality. Differential diagnosis includes other causes of central neonatal cyanosis. Palliative treatment with prostaglandin E1 and balloon atrial septostomy are usually required soon after birth. Surgical correction is performed at a later stage. Usually, the Jatene arterial switch operation is the procedure of choice. Whenever this operation is not feasible, adequate alternative surgical approach should be implemented. With the advent of newer and improved surgical techniques and post operative intensive care, the long-term survival is approximately 90% at 15 years of age. However, the exercise performance, cognitive function and quality of life may be impaired.

    Full Text Available Encryption is a technique to secure sounds data from attackers. In this study, transposition technique that corresponds to a WAV file extension is used. The performance of the transposition technique is measured using the mean square error (MSE. In the test, the value of MSE of the original and encrypted audio files were compared; the original and decrypted audio files used the correct password is ‘SEMBILAN’ and the incorrect password is ‘DELAPAN’. The experimental results showed that the original and encrypted audio files, and the original and decrypted audio files used the correct password that has a value of MSE = 0, and with the incorrect one with a value of MSE 0.00000428 or ? 0. In other words, the transposition technique is able to ensure the security of audio data files.

  13. Transpositions and malpositions of the great arteries

    International Nuclear Information System (INIS)

    The transposition of the great arteries afters to an abnormal connection and relation of the great arteries in which the aorta arises from the morphologic right ventricle and the pulmonary artery from the morphologic left ventricle, while the malposition of the great arteries indicates an abnormal relationship between the great arteries in which the great arteries are not transposed across the ventricular septum but they are malposed, as is seen in double outlet right ventricle, double outlet left ventricle and single ventricles. Transpositions and malpositions of the great arteries are understood as a spectrum of malformation caused by abnormal conal development and can be included in the common category of 'conotruncal malpositions'. Authors analized 32 cases of transpositions and malpositions of the great arteries in which cineangiocardiographies were done at the Department of Radiology, Seoul National University Hospital in recent 17 months, with specific references to the segmental combinations, the types of conus and the relations and courses of the great arteries. The results are as follows; 1. Cases included are 8 cases of complete transposition of the great arteries, 9 cases of corrected transposition of the great arteries, 12 cases of double outlet right ventricle, 1 case of anatomically corrected malposition of the great arteries, 1 cases of double inlet left ventricle and 1 case of double inlet right ventricle. 2. Types of conus are subaortic in 19 and bilateral in 13. In 19 cases with subaortic conus, 17 are transposition of the great arteries and 2 are double inlet left ventricle and double inlet right ventricle. In 13 cases with bilateral conus, 12 are double outlet right ventricle and 1 is anatomically corrected malposition of the great arteries. 3.High tendency of side-by-side interrelationship of semilunar valves is noted in cases with corrected transposition of the great arteries. But there is no characteristic tendency of side-by-side ro anterior-posterior semilunar interrelationship in cases with complete transposition of the great arteries and double outlet right ventricle. 4. There are two cases of exception to 'loop rule' 5. There are two cases of exception to 'visceroatrial concordance rule'. 6. Inappropriate position of aortic arch, i. e., right arch in situs solitus and left arch in situs inversus, is noted in 4 cases. 7. For more accurate diagnosis, selective biventriculography using biplane cineradiography is necessary

  18. Radionuclide evaluation of unilateral pulmonary vein stenosis

    International Nuclear Information System (INIS)

    Evaluation of pulmonary vein stenosis (PVS) can be difficult especially if the stenosis is of a minor degree or in presence of a negative chest roentgenogram. Such a problem was encountered in one of our patients who showed varying degrees of PVS during her hospital course for closure of a a secundum atrial septal defect. First pass radionuclide cardiopulmonary angiography (FPRCPA) was employed in the evaluation of PVS. Results of comparative computer analysis of different ''areas of interest'' seem to suggest that FPRCPA is capable of picking up minor degrees of PVS. Since FPRCPA is non-invasive, it may be an excellent method of evaluating patients who are predisposed to developing PVS, e.g. post-Mustard or Senning repair for transposition of great arteries and, possibly, patients who have had repair of total anomalous pulmonary venous connection

    2015-06-01

    Downy mildew, caused by the oomycete Peronospora belbahrii, is a devastating disease of sweet basil. In this study, 113 accessions of Ocimum species (83 Plant Introduction entries and 30 commercial entries) were tested for resistance against downy mildew at the seedling stage in growth chambers, and during three seasons, in the field. Most entries belonging to O. basilicum were highly susceptible whereas most entries belonging to O. americanum, O. kilimanadascharicum, O. gratissimum, O. campechianum, or O. tenuiflorum were highly resistant at both the seedling stage and the field. Twenty-seven highly resistant individual plants were each crossed with the susceptible sweet basil 'Peri', and the F1 progeny plants were examined for disease resistance. The F1 plants of two crosses were highly resistant, F1 plants of 24 crosses were moderately resistant, and F1 plants of one cross were susceptible, suggesting full, partial, or no dominance of the resistance gene(s), respectively. These data confirm the feasibility of producing downy mildew-resistant cultivars of sweet basil by crossing with wild Ocimum species. PMID:25844828

    In list memory, access to individual items reflects limits of temporal distinctiveness. This is reflected in the finding that neighbouring list items tend to be confused most often. This article investigates the analogous effect of spatial proximity in a visual working-memory task. Items were presented in different locations varying in spatial distance. A retro-cue indicated the location of the item relevant for the subsequent memory test. In two recognition experiments, probes matching spatially close neighbours of the relevant item led to more false alarms than probes matching distant neighbours or non-neighbouring memory items. In two probed-recall experiments, one with simultaneous, the other with sequential memory item presentation, items closer to the cued location were more frequently chosen for recall than more distant items. These results reflect a spatial transposition gradient analogous to the temporal transposition gradient in serial recall and challenge fixed-capacity models of visual working memory (WM).

  3. Coping with EU environmental legislation : transposition principles and practices

    DEFF Research Database (Denmark)

    Anker, Helle Tegner; de Graaf, Kars

    2015-01-01

    A ‘burden reducing’ agenda has spurred an increased interest in how EU environmental legislation is transposed into national legislation—most prominently reflected in the principle of ‘no gold-plating’. Yet, an important question is to what extent transposition principles and practices may ensure a coherent and accessible body of environmental legislation, while at the same time ensuring adequate transposition of EU environmental legislation. This article analyses the existence, or emergence, of transposition principles and practices in three Member States—the United Kingdom, the Netherlands and Denmark. It also examines how EU initiatives may influence these principles and practices. The article concludes that the steering of transposition processes by general transposition principles and objectives alone, and in particular those dominated by a ‘burden reducing’ agenda, has a limited focus on coherence and accessibility with respect to environmental legislation and that such issues deserve more attention in the transposition process.

  4. Corrected transposition of the great arteries

    International Nuclear Information System (INIS)

    The corrected transposition of the great arteries is an usual congenital cardiac malformation, which consists of transposition of great arteries and ventricular inversion, and which is caused by abnormal development of conotruncus and ventricular looping. High frequency of associated cardiac malformations makes it difficult to get accurate morphologic diagnosis. A total of 18 cases of corrected transposition of the great arteries is presented, in which cardiac catheterization and angiocardiography were done at the Department of Radiology, Seoul National University Hospital between September 1976 and June 1981. The clinical, radiographic, and operative findings with the emphasis on the angiocardiographic findings were analyzed. The results are as follows: 1. Among 18 cases, 13 cases have normal cardiac position, 2 cases have dextrocardia with situs solitus, 2 cases have dextrocardia with situs inversus and 1 case has levocardia with situs inversus. 2. Segmental sets are (S, L, L) in 15 cases, and (I, D,D) in 3 cases and there is no exception to loop rule. 3. Side by side interrelationships of both ventricles and both semilunar valves are noticed in 10 and 12 cases respectively. 4. Subaortic type conus is noted in all 18 cases. 5. Associated cardic malformations are VSD in 14 cases, PS in 11, PDA in 3, PFO in 3, ASD in 2, right aortic arch in 2, tricuspid insufficiency, mitral prolapse, persistent left SVC and persistent right SVC in 1 case respectively. 6. For accurate diagnosis of corrected TGA, selective biventriculography using biplane cineradiography is an essential procedure

    The successful diagnosis, surgical planning, and long-term care of children with transposition of the great arteries require high-quality cardiac imaging with echocardiography. Echocardiography must identify the relevant anatomic variants of transposition of the great arteries, such as of ventricular septal defects and aortic arch anomalies. Methodical and detailed imaging of the coronary arteries is particularly important, as translocation of the coronary arteries is a critical component of the arterial switch procedure. Familiarity with the potential coronary artery variants and the ideal imaging planes is essential for an echocardiographer. Knowledge of both the early and late complications following the arterial switch procedure is essential to optimise post-operative echocardiography. These complications can include residual lesions leading to haemodynamic compromise or progressive late phenomena, such as aortic root dilatation and aortic insufficiency. Echocardiography will continue to be the cornerstone to the lifelong management of transposition of the great arteries, and improvements in technology and increased familiarity with modalities such as stress echocardiography will enhance the role of advanced imaging even further.

    Modelling of human disease in genetically engineered pigs provides unique possibilities in biomedical research and in studies of disease intervention. Establishment of methodologies that allow efficient gene insertion by non-viral gene carriers is an important step towards development of new disease models. In this report, we present transgenic pigs created by Sleeping Beauty DNA transposition in primary porcine fibroblasts in combination with somatic cell nuclear transfer by handmade cloning. Göttingen minipigs expressing green fluorescent protein are produced by transgenesis with DNA transposon vectors carrying the transgene driven by the human ubiquitin C promoter. These animals carry multiple copies (from 8 to 13) of the transgene and show systemic transgene expression. Transgene-expressing pigs carry both transposase-catalyzed insertions and at least one copy of randomly inserted plasmid DNA. Our findings illustrate critical issues related to DNA transposon-directed transgenesis, including coincidental plasmid insertion and relatively low Sleeping Beauty transposition activity in porcine fibroblasts, but also provide a platform for future development of porcine disease models using the Sleeping Beauty gene insertion technology.

    Basil (Ocimum spp.) is one of the most economically important and widely grown herbs in the world. Basil downy mildew, caused by Peronospora belbahrii, has become an important disease in sweet basil (O. basilicum) production worldwide in the past decade. Global sweet basil production is at significant risk to basil downy mildew because of the lack of genetic resistance and the ability of the pathogen to be distributed on infested seed. Controlling the disease is challenging and consequently many crops have been lost. In the past few years, plant breeding efforts have been made to identify germplasm that can be used to introduce downy mildew resistance genes into commercial sweet basils while ensuring that resistant plants have the correct phenotype, aroma, and tastes needed for market acceptability. Fungicide efficacy studies have been conducted to evaluate current and newly developed conventional and organic fungicides for its management with limited success. This review explores the current efforts and progress being made in understanding basil downy mildew and its control. PMID:25894318

    2014-01-01

    Starting from Rogoff’s (1990) theory of apprenticeship in thinking and Apter’s (1987) reversal theory, this paper discusses the formulation of PlayDT (Playful Domain Transposition), a new approach to support the transposition of complex concepts, from different knowledge domains, into playful interactions, through the design of interactive media. PlayDT aims at facilitating the creation of a creative and easy understandable mapping between knowledge and interaction within the game. Multiple representations are encouraged, so to allow learners to express their own preferences, regarding their play experience. This study is based on reflections on three design-oriented research projects. The first one is MicroCulture (?C), a mixed-reality game, aimed at supporting learning of historical processes during guided tours in museums; it is targeted to primary school children. ?C was developed through a participatory design process, involving task-supported interviews and co-design workshops with children between 9 and 12. Among the findings, a strategy to map knowledge into interactions emerged, together with rich insights about children’s different approaches to play. In an attempt to evaluate the knowledge mapping, we designed PrimeSlaughter, a computer game aimed at supporting learning of prime numbers and factorization, for later primary and early secondary school pupils; the same domain concepts were mapped into two play styles in the game. In this study, we intend to go further in our formulation of the PlayDT approach, through another design study, aimed at creating a game to support learning of the Fourier Transform. In order to generalize further the mapping approach, a participatory workshop was conducted with university students, who provided inspirations to map the Fourier Transform into different games and various play styles. Reflections on these studies provide a solid grounding to define the PlayDT approach, its different stages, and implications for learning practice.

    2009-12-01

    Full Text Available Abstract Background hAT elements and V(DJ recombination may have evolved from a common ancestral transposable element system. Extrachromosomal, circular forms of transposable elements (referred to here as episomal forms have been reported yet their biological significance remains unknown. V(DJ signal joints, which resemble episomal transposable elements, have been considered non-recombinogenic products of V(DJ recombination and a safe way to dispose of excised chromosomal sequences. V(DJ signal joints can, however, participate in recombination reactions and the purpose of this study was to determine if hobo and Hermes episomal elements are also recombinogenic. Results Up to 50% of hobo/Hermes episomes contained two intact, inverted-terminal repeats and 86% of these contained from 1-1000 bp of intercalary DNA. Episomal hobo/Hermes elements were recovered from Musca domestica (a natural host of Hermes, Drosophila melanogaster (a natural host of hobo and transgenic Drosophila melanogaster and Aedes aegypti (with autonomous Hermes elements. Episomal Hermes elements were recovered from unfertilized eggs of M. domestica and D. melanogaster demonstrating their potential for extrachromosomal, maternal transmission. Reintegration of episomal Hermes elements was observed in vitro and in vivo and the presence of Hermes episomes resulted in lower rates of canonical Hermes transposition in vivo. Conclusion Episomal hobo/Hermes elements are common products of element excision and can be maternally transmitted. Episomal forms of Hermes are capable of integration and also of influencing the transposition of canonical elements suggesting biological roles for these extrachromosomal elements in element transmission and regulation.

    Full Text Available Essential oil compositions of aerial parts from twelve basil cultivars (Ocimum spp were analysed by gas chromatography-mass spectrometry (GC-MS. Ten of them were characterized by the presence of a high percentage of methyl cinnamate (35-80%, which defined the chemotype for these varieties. Only one presented the caryophyllene chemotype and another, the linalool chemotype. Three of the basils, "purple ruffles", "little virgin" and "purple virgin" exhibited the methyl cinnamate > linalool subtype. "White compact" and "white ruffles" showed the methyl cinnamate > linalool > 1,8-cineole subtype. Methyl cinnamate > methyl eugenol was the subtype for "purple castle". The variety "large green leaves" exhibited the linalool > methyl cinnamate subtype. Caryophyllene > methyl eugenol subtype was determined for "clove basil". The rest of the basils "cinnamon", "purple lovingly", "sweet castle" and "purple long-legged", belonged to the methyl cinnamate chemotype in which methyl cinnamate constituted more than 62% of the total essential oil content.

  1. Rapid Staining Method to Detect and Identify Downy Mildew (Peronospora belbahrii in Basil

    Directory of Open Access Journals (Sweden)

    Adolfina R. Koroch

    2013-07-01

    Full Text Available Premise of the study: Demand for fresh-market sweet basil continues to increase, but in 2009 a new pathogen emerged, threatening commercial field/greenhouse production and leading to high crop losses. This study describes a simple and effective staining method for rapid microscopic detection of basil downy mildew (Peronospora belbahrii from leaves of basil (Ocimum basilicum. Methods and Results: Fresh leaf sections infected with P. belbahrii were placed on a microscope slide, cleared with Visikol™, and stained with iodine solution followed by one drop of 70% sulfuric acid. Cell walls of the pathogen were stained with a distinct coloration, providing a high-contrast image between the pathogen and plant. Conclusions: This new staining method can be used successfully to identify downy mildew in basil, which then can significantly reduce its spread if identified early, coupled with mitigation strategies. This technique can facilitate the control of the disease, without expensive and specialized equipment.

  2. Universal platform for quantitative analysis of DNA transposition

    Directory of Open Access Journals (Sweden)

    Pajunen Maria I

    2010-11-01

    Full Text Available Abstract Background Completed genome projects have revealed an astonishing diversity of transposable genetic elements, implying the existence of novel element families yet to be discovered from diverse life forms. Concurrently, several better understood transposon systems have been exploited as efficient tools in molecular biology and genomics applications. Characterization of new mobile elements and improvement of the existing transposition technology platforms warrant easy-to-use assays for the quantitative analysis of DNA transposition. Results Here we developed a universal in vivo platform for the analysis of transposition frequency with class II mobile elements, i.e., DNA transposons. For each particular transposon system, cloning of the transposon ends and the cognate transposase gene, in three consecutive steps, generates a multifunctional plasmid, which drives inducible expression of the transposase gene and includes a mobilisable lacZ-containing reporter transposon. The assay scores transposition events as blue microcolonies, papillae, growing within otherwise whitish Escherichia coli colonies on indicator plates. We developed the assay using phage Mu transposition as a test model and validated the platform using various MuA transposase mutants. For further validation and to illustrate universality, we introduced IS903 transposition system components into the assay. The developed assay is adjustable to a desired level of initial transposition via the control of a plasmid-borne E. coli arabinose promoter. In practice, the transposition frequency is modulated by varying the concentration of arabinose or glucose in the growth medium. We show that variable levels of transpositional activity can be analysed, thus enabling straightforward screens for hyper- or hypoactive transposase mutants, regardless of the original wild-type activity level. Conclusions The established universal papillation assay platform should be widely applicable to a variety of mobile elements. It can be used for mechanistic studies to dissect transposition and provides a means to screen or scrutinise transposase mutants and genes encoding host factors. In succession, improved versions of transposition systems should yield better tools for molecular biology and offer versatile genome modification vehicles for many types of studies, including gene therapy and stem cell research.

    The surgical treatment for d-transposition has evolved dramatically since the inception of cardiac surgery in the 1950s. Today, the arterial switch operation is employed almost exclusively in the management of this disease unless significant left ventricular outflow obstruction is present. Surgical options for these patents are reviewed and an in-depth technical discussion of arterial switch for d-transposition of the great arteries/intact ventricular septum follows. PMID:25918115

    2003-01-01

    Essential oil compositions of aerial parts from twelve basil cultivars (Ocimum spp) were analysed by gas chromatography-mass spectrometry (GC-MS). Ten of them were characterized by the presence of a high percentage of methyl cinnamate (35-80%), which defined the chemotype for these varieties. Only one presented the caryophyllene chemotype and another, the linalool chemotype. Three of the basils, "purple ruffles", "little virgin" and "purple virgin" exhibited the methyl cinnamate > linalool su...

    Basil-containing plant food supplements (PFS) can contain estragole which can be metabolised into a genotoxic and carcinogenic 1'-sulfoxymetabolite. This study describes the inhibition of sulfotransferase (SULT)-mediated bioactivation of estragole by compounds present in basil-containing PFS. Results reveal that PFS consisting of powdered basil material contain other compounds with considerable in vitro SULT-inhibiting activity, whereas the presence of such compounds in PFS consisting of basi...

  7. Uranium veins in Portugal

    International Nuclear Information System (INIS)

    Vein-type uranium deposits in Portugal demonstrate a broad temporal and physical spectrum from intragranitic hydrothermal jasper-type veins formed at moderately high temperatures, through lower temperature quartz veins and peribatholithic disseminated mineralization of 'Iberian-type', to undoubted supergene enrichments in surface-related planar traps such as weathered basic dikes. All appear to be in close spatial relationship to 'fertile' Hercynian granites in which uraninite of low thorium content is the main contributor to the enriched uranium levels. The availability of this large source of labile uranium, a pervasive fracture network and a series of tectonic and intrusive events which could generate hydrothermal circulation, allow several alternative genetic models for the mineralization. It now appears that the classic hydrothermal pitchblende veins within the granite are most likely of late-Hercynian age. Many of the mineralogical and depositional characteristics of the lower temperature 'Iberian-type' deposits suggest a temporal continuity to this mineralization but, as yet, no supporting age data are available. It is conceded, therefore, that a considerable time-gap could occur between the two episodes, with the peribatholithic mineralization resulting from later rejuvenation of the hydrothermal convective system.

  10. The hyperbolic geometry of random transpositions

    2004-01-01

    Make the set of permutations of $n$ objects into a graph $G_n$ by connecting two permutations that differ by one transposition, and let $\\sigma_t$ be the continuous time simple random walk on this graph. In a previous paper, Berestycki and Durrett (2004) showed that the limiting behavior of the distance from the identity at time $cn/2$ has a phase transition at $c=1$. When $c1$ it is $u(c)n$ with $u(c) < c/2$. Here we investigate some consequences of this result for the geometry of $G_n$. Our first result is that when we consider the sphere of radius $an$ centered at the origin, and pick two points independently according to the hitting distribution, then Gromov hyperbolicity breaks down at critical radius $a=1/4$. When $a<1/4$ the space is hyperbolic but also displays behavior that is much different from manifolds of negative curvature - it is shown that there are many geodesics that may travel much different paths to get to a point. We also show that the hitting distribution of the sphere of radius $a...

  11. The response of sweet basil (Ocimum basilicum L. to the application of growth stimulators and forecrops

    2012-12-01

    Full Text Available A field experiment in growing sweet basil was carried out in the period 2008-2010 in Fajs?awice (Lublin region, on podzolic soil. The study evaluated the biometric traits of the plants, yield, the qualitative parameters of herbal raw material and weed infestation of the crop in dependence on growth simulators (Asahi SL, Bio-algeen, Titanit and the forecrop (winter wheat or spring barley + white mustard cover crop. Plots without foliar application of the growth stimulators were the control treatment. Tillage, mineral NPK fertilization as well as mechanical and chemical weed control were typical for this plant species and consistent with the recommendations for herbal plant protection. A hypothesis was made that the application of growth stimulators would have a positive effect on basil productivity, raw material quality and weed infestation of the basil crop. It was also assumed that the phytosanitary and fertilizing effects of the cover crop would result in higher and qualitatively better yield compared to the cereal forecrop alone (winter wheat. The best quantitative parameters of sweet basil raw material and the highest reduction in air-dry weight of weeds in the crop were observed after the application of the growth stimulators. The forecrop - spring barley + a white mustard cover crop that is ploughed in - also had a beneficial effect on yield and weed infestation of the plant in question. The traditional crop protection method used in the basil crop, without the application of the growth stimulators, resulted in a lower plant height and a smaller number of shoots per plant. This caused higher weed infestation of the crop and a decrease in yield. The positive side of the non-application of growth stimulators was a better chemical composition of basil raw material. Asahi SL and Tytanit yielded the best growth and productivity of the basil plants.

  12. Management of varicose veins.

    Jones, Richard H; Carek, Peter J

    2008-12-01

    Varicose veins are twisted, dilated veins most commonly located on the lower extremities. Risk factors include chronic cough, constipation, family history of venous disease, female sex, obesity, older age, pregnancy, and prolonged standing. The exact pathophysiology is debated, but it involves a genetic predisposition, incompetent valves, weakened vascular walls, and increased intravenous pressure. A heavy, achy feeling; itching or burning; and worsening with prolonged standing are all symptoms of varicose veins. Potential complications include infection, leg ulcers, stasis changes, and thrombosis. Some conservative treatment options are avoidance of prolonged standing and straining, elevation of the affected leg, exercise, external compression, loosening of restrictive clothing, medical therapy, modification of cardiovascular risk factors, reduction of peripheral edema, and weight loss. More aggressive treatments include external laser treatment, injection sclerotherapy, endovenous interventions, and surgery. Comparative treatment outcome data are limited. There is little evidence to preferentially support any single treatment modality. Choice of therapy is affected by symptoms, patient preference, cost, potential for iatrogenic complications, available medical resources, insurance reimbursement, and physician training.

    2015-01-01

    Full Text Available The history of surgery for transposition of great arteries (TGA has paralleled the history of cardiac surgery. In fact, it began before the birth of open heart surgery when the palliative Blalock-Hanlon septectomy was first performed in 1948. The atrial switch, which was an attempt to correct the physiology of transposition, had significant shortcomings. The arterial switch sought to address them. This has emerged as an anatomically as well as physiologically appropriate solution. Today we continue to pursue technical refinements as well as try to expand the indications of the arterial switch. This review traces the various milestones in this perpetual journey.

    2011-01-01

    Full Text Available In Serbia basil has been grown traditionally as a decorative, medicinal, seasoning and ritual herb, and there is a variety of different populations of basil. Basil is considered to have been brought to Serbia in the 12th century by monks returning from their pilgrimages. Essential oils isolated from herb of ten basil populations traditionally grown on the territory of the Republic of Serbia have been analyzed. The selected populations have been designated under codes from T-1 to T-10 and deposited in the Plant Genes Bank at Serbia and at the Institute for Crop Sciences of the Faculty of Agriculture in Belgrade. Essential oils of all tested basil populations were light yellow and had a specific aromatic scent. The composition of essential oil in the dry herb of the tested populations ranged from 0.87 to 1.84%. The results of gas chromatographic analysis of essential oils in tested basil populations pointed to their complex chemical composition and to the fact that they belong to the most appreciated European chemotype. In total thirty three components have been identified in the essential oils. The most common fraction of components in all tested oils was terpenoides. The predominant component in all essential oils is monoterpen linalol, ranging from 51.52 to 74.73%. Phenylpropranoid methylchavicol ranged from 2.49 to 18.97%. Essential oils of populations T-6, T-7, T-8 and T-10 were characterized by elevated 1.8-cineol (4.44, 3.70, 4.01 and 3.43%, respectively. Populations T-3 and T-4 in essential oil contained higher percent of geraniol (4.27 and 3.31%, respectively. In all ten essential oils sesquiterpen fraction consisted of greater number of components, with germacrene having special significance as it was found in high percentage in all populations. The highest content of germacrene was registered in population T-9 (4.30%, T-10 (4.18%, while in others it ranged from 2.17 to 3.69%. Basil populations traditionally grown in Serbia have exceptional quality. They represent an excellent raw material for the production of basil essential oils, for the needs of pharmaceutical, food and chemical industry.

  15. Efficient sleeping beauty DNA transposition from DNA minicircles

    DEFF Research Database (Denmark)

    Sharma, Nynne; Cai, Yujia

    2013-01-01

    DNA transposon-based vectors have emerged as new potential delivery tools in therapeutic gene transfer. Such vectors are now showing promise in hematopoietic stem cells and primary human T cells, and clinical trials with transposon-engineered cells are on the way. However, the use of plasmid DNA as a carrier of the vector raises safety concerns due to the undesirable administration of bacterial sequences. To optimize vectors based on the Sleeping Beauty (SB) DNA transposon for clinical use, we examine here SB transposition from DNA minicircles (MCs) devoid of the bacterial plasmid backbone. Potent DNA transposition, directed by the hyperactive SB100X transposase, is demonstrated from MC donors, and the stable transfection rate is significantly enhanced by expressing the SB100X transposase from MCs. The stable transfection rate is inversely related to the size of circular donor, suggesting that a MC-based SB transposition system benefits primarily from an increased cellular uptake and/or enhanced expression which can be observed with DNA MCs. DNA transposon and transposase MCs are easily produced, are favorable in size, do not carry irrelevant DNA, and are robust substrates for DNA transposition. In accordance, DNA MCs should become a standard source of DNA transposons not only in therapeutic settings but also in the daily use of the SB system.Molecular Therapy - Nucleic Acids (2013) 2, e74; doi:10.1038/mtna.2013.1; published online 26 February 2013.

  17. Pulmonary blood flow distribution in transposition of the great arteries

    International Nuclear Information System (INIS)

    Pulmonary blood flow distribution was studied by scintillation scanning of the lungs after the infusion of iodine-131-labeled macroaggregates of human albumin before and after the Mustard operation in 53 patients with transposition of the great arteries. The patients were classified as follows: Group 1 (24 infants with uncomplicated transposition of the great arteries); Group II (18 patients with transposition and ventricular septal defect); and Group III (11 patients with transposition, ventricular septal defect and pulmonary obstruction). Before operation, 21 patients had a normal distribution of pulmonary blood flow, 10 had preferential flow to the right lung and 2 had preferential flow to the left lung. After operation, 19 had a normal pattern of pulmonary blood flow, 21 had preferential flow to the right lung and 3 had preferential flow to the left lung. The scanning studies have proved helpful in follow-up of patients to rule out recurrence of the shunt, pulmonary or systemic venous obstruction, development of pulmonary hypertension and occlusion of a palliative systemic-pulmonary shunt

    Heterotaxy syndromes comprise a great variety of possible cardiac defects. Anomalies of the pulmonary venous system are well recognized in heterotaxy syndromes but constitute a frequently underdiagnosed subgroup. The case report describes a girl with a rare form of supracardiac total anomalous pulmonary venous return via a right-sided vertical vein to the right innominate vein in heterotaxy syndrome with dextrocardia, unbalanced atrioventricular septal defect with severe left ventricular hypoplasia, and transposition of the great arteries with pulmonary stenosis. Careful evaluation and imaging before surgical repair is crucial for such complex cardiac anomalies. PMID:22354227

    Full Text Available Pediatric electrophysiology, especially in infants, is the most difficult area of clinical arrhythmology. For the last two decades radiofrequency catheter ablation (RFCA in pediatric patients has been dramatically advanced. Due to this progress the complication rate has been decreased and success rate has been improved. In cases, when arrhythmia can’t be controlled with drugs and becomes life-threatening (takes incessant character, sings of heart failure develop RFCA is considered to be the method of choice. The most common cause of tachyarrhythmias in children is an accessory pathway (AP. Elimination of AP at an early age can be technically challenging due to small body surface area, limitation of invasion and proved high rate of complications if a patient weighs less than 15 kgs. There are no published data on the long-term effects of RFCA on coronary arteries and myocardial function. Although animal studies showed RF lesion can expand with time and may affect coronary perfusion. A combination of congenital heart disease and incessant tachyarrhythmia is even more difficult to treat. In this article we present a case report of successful RFCA of AP in 4-months-old patient with corrected transposition of great arteries, Ebstein's like modification of tricuspid «arterial» valve, heart failure NYHA II and intraoperatively revealed thrombosis of femoral veins.

  1. Obstruction of superior vena cava following the Mustard operation of transposition of great arteries

    International Nuclear Information System (INIS)

    The obstruction of the superior vena cava is a frequent late complication of the Mustard operation of the transposition of great arteries. Although it is asymptomatic, it threatens the patient as intracranial hypertension develops. Radionuclide angiocardiography can visualize the collateral blood flow from the obturated vena cava superior by the system of the azygos and hemiazygos veins into inferior vena cava. The benefit of this noninvasive method for screening obstruction was tested in a group of 94 patients. The obstruction of the vena cava superior was apparent in 11 patients (11.7%). In all cases, the diagnosis was confirmed by catheterization and angiocardiography. Pulsed Doppler echocardiography proved an abnormal flow in the vena cava superior in 9 patients. In other five patients with abnormal flow, obstruction was not revealed by radionuclide angiocardiography. Radionuclide angiocardiography supplements echocardiography also as regards other late complications and can be thus recommended for routine examinations of patients after the Mustard operation.

    Full Text Available Ocimum basilicum L. belongs to the family Lamiaceae is an herb that is extensively cultivated in some countries. Areal parts, especially leaves of sweet basil are widely used to enhance the flavour of foods such as salads, pasta, tomato products, vegetables, pizza, meat, soups, marine foods, confectioneries and other products. Essential oil yield and chemical components of two Iranian landraces of sweet basil including “Purple” and “Green” grown south-central of Iran (Isfahan province were investigated. The hydro-distillated oils were analyzed by GC-MS. The oil yields were obtained from the aerial of Purple with 0.56 ml/100 g dry matter and the aerial of Green with 0.48 ml/100 g dry matter. Results indicated significant differences (p < 0.01 among the aerial for the main constituents in the essential oil from two Iranian landraces of sweet basil. The major constituents of the essential oil from the aerial of Purple landrace were methyl chavicol or estragol (63.32% and linalool (7.96%. The main compositions of the essential oil from the aerial of Green landrace were methyl chavicol (31.82%, geranial (24.60% and neral (22.65%. Genarlly, a comparison of our results with the previous reports suggests differences in the essential oil compositions and oil yield of the plant material could be attributed to genetic diversity in two Iranian landraces of sweet basil.

    The consumption and use of edible flowers as food is growing; however, no study has been conducted to evaluate their role in the cause of food-borne illness or in food safety. Recent food-borne outbreaks traced to fresh herbs have raised concern about their processing and handling. Basil, one of the most commonly used fresh herbs, has been identified as a source of food-borne illness. Baseline assessments of microflora were performed, and the microbial diversity between growing methods (organic vs. conventional) was compared. DNA sequencing was used to identify the microbial flora present on fresh edible flower and basil samples. The most predominant species identified were Enterobacter hormaechei (10%), Acinetobacter calcoaceticus (10%), Enterobacter ludwigii (10%), Enterobacter asburiae (6%), and Enterobacter cowanii (6%). Pseudomonas aeruginosa (6%), Salmonella enterica (6%), and Bacillus amyloliquefaciens (2%) were also isolated. Phylogenetic analysis showed that most species of isolated bacteria belonged to the phyla Gammaproteobacteria (81.2%) and Firmicutes (18.8%). Statistical analysis, diversity index for species richness, and lineage-per-time plots showed that for basil, organically grown samples had a higher microbial diversity than conventionally grown samples. Edible flowers and basil are often grown using organic methods and are commonly consumed raw without any washing or cooking, to preserve aesthetic value, but these practices may pose a potential risk for food-borne illness. The baseline assessment, together with phylogenetic and statistical analyses, indicated possible microbial contamination in edible flowers and basil. The use of statistical estimation of molecular diversity based on the 16S rRNA sequences and lineage-per-time plots with phylogenetic analysis well served as a means for comparing microbial diversity in food samples between the growing methods (organic vs. conventional).

Seeds were germinated on a temperature-gradient bar varying between 5 and 40 °C (with 5 °C intervals. Results indicated that the highest germination percentage of hyssop (92-98%, sweet basil (86-90% and oregano (74-77% occurred at 20-30 °C, 25-30 °C and 20-30 °C, respectively; therefore, moderate and warm temperatures are proper for germination of all species. In all species the maximum germination rate obtained at 30 °C. Among all species, Day 10 % of Sweet basil Germination had the lowest value, which indicates faster germination. The cardinal temperatures (base, optimum and ceiling or maximum were estimated by the segmented model. Base temperature (Tb was calculated for hyssop, sweet basil and oregano as 3.42, 5.70 and 5.46 °C, respectively. Optimal temperature (To calculated for all species was approximately 30°C, So warmer temperatures are much more proper for them. The species showed different maximum temperatures (Tm from 42.91 (Oregano to 48.05 °C (Hyssop. In Hyssop and Sweet basil optimum growth of seedlings were observed at 30°C while Oregano reached its best growth at 25°C. The difference between maximum and minimum temperatures of germination knowing as temperature range (TR index could show adaptation capability to broad sites for planting and domestication. Regarding this index Hyssop stood in the first place.

    The purpose of this article is to review the basic embryology and anatomy of the pulmonary veins and the various imaging techniques used to evaluate the pulmonary veins, as well as the radiologic findings in diseases affecting these structures. Specific cases highlight the clinical importance of the imaging features, particularly the findings obtained with multidetector computed tomography (CT). Pulmonary vein disease can be broadly classified into congenital or acquired conditions. Congenital disease, which often goes unnoticed until patients are adults, mainly includes (a) anomalies in the number or diameter of the vessels and (b) abnormal drainage or connection with the pulmonary arterial tree. Acquired disease can be grouped into (a) stenosis and obstruction, (b) hypertension, (c) thrombosis, (d) calcifications, and (e) collateral circulation. Pulmonary vein stenosis or obstruction, which often has important clinical repercussions, is frequently a result of radiofrequency ablation complications, neoplastic infiltration, or fibrosing mediastinitis. The most common cause of pulmonary venous hypertension is chronic left ventricular failure. This condition is difficult to differentiate from veno-occlusive pulmonary disease, which requires a completely different treatment. Pulmonary vein thrombosis is a rare, potentially severe condition that can have a local or distant cause. Calcifications have been described in rheumatic mitral valve disease and chronic renal failure. Finally, the pulmonary veins can act as conduits for collateral circulation in cases of obstruction of the superior vena cava. Multidetector CT is an excellent modality for imaging evaluation of the pulmonary veins, even when the examination is not specifically tailored for their assessment. PMID:23842969

  11. Didactic Transposition : From theoretical notion to research programme

    DEFF Research Database (Denmark)

    Achiam, Marianne

    The term didactic transposition refers to the deconstruction and reconstruction of science knowledge, values or practices in order to make them teachable. In this paper, I present the theoretical framework that has grown around this notion. I use examples from different levels of science education and different subjects to illustrate how science is transformed in any teaching undertaking, and how that transformation influences the way science is experienced and appropriated by learners. The chosen examples also illustrate the development of the notion of didactic transposition from a descriptive framework to the more normative construct of today (the Anthropological Theory of Didactics or ATD), where it converges with other comparable frameworks, e.g. the Model of Educational Reconstruction.

    20 patients with the diagnosis of congenital corrected transposition of great arteries were analyzed. The diagnosis was based on routine clinical examination, echocardiography and in certain cases on heart catheterization and angiocardiography. In the most cases c-TGA coexists with additional heart defects. The commonest coexisting defects were: ventricular septal defect (60%), pulmonary stenosis (50%), atrio-ventricular valve regurgitation, predominantly systemic (tricuspid 45%). In the most cases 2D Doppler echo examination was sufficient for morphological assessment. In order to quality to cardiosurgical treatment heart catheterization and angiocardiography were necessary. 5 children were treated surgically. 3 of them underwent palliative procedures, one - Rastelli procedure and one had corrective surgery with bad result. Clinical picture of corrected transposition of great arteries is determined by coexisting additional heart defects. (author) 15 refs, 6 figs, 1 tab

    Transposition of the great arteries was once an almost uniformly fatal disease in infancy. Six decades of advances in surgical techniques, intraoperative care, and perioperative management have led to at least 90% of patients reaching adulthood, most with a good quality of life. This review summarizes medical and surgical decision making during the neonatal perioperative period, with a special emphasis on factors pertinent to the anesthetic evaluation and care during primary surgical repair of transposition of the great arteries. A review is also provided of anesthetic considerations for noncardiac surgery later in childhood or adulthood, for those survivors of the arterial switch operation, Rastelli procedure, Nikaidoh procedure, and the réparation á l'étage ventriculaire procedure.

    Recent studies in mammals have documented the neural expression and mobility of retrotransposons and have suggested that neural genomes are diverse mosaics. We found that transposition occurs among memory-relevant neurons in the Drosophila brain. Cell type-specific gene expression profiling revealed that transposon expression is more abundant in mushroom body (MB) ?? neurons than in neighboring MB neurons. The Piwi-interacting RNA (piRNA) proteins Aubergine and Argonaute 3, known to suppress ...

    The aim of this study is the transposition of an exothermic reaction carried out in a batch reactor to a continuous intensified one. The esterification of propionic anhydride with 2- butanol was selected as a case study. The decomposition reactions of the reactants and the products were studied by DSC whereas the heat of solution of the two reactants were determined by isothermal calorimetry. An extensive experimental programme was then carried out using the Mettler RC-1 reaction calorimeter ...

    Using the conjugative transposon Tn916, we have identified a closed covalent circular form produced in vivo that is able to serve as an intermediate in transposition. When a region of a streptococcal chromosome containing Tn916 is cloned in an Escherichia coli plasmid, supercoiled transposon molecules are excised spontaneously. The purified supercoiled forms transform Bacillus subtilis protoplasts by inserting into the chromosome, apparently at random. In B. subtilis, Tn916 retains its abilit...

    Aortic atresia occurring with complete transposition of the great arteries (ventriculoarterial discordance) has not previously been reported. A patient with this condition is described, who is alive and relatively well at the age of 6 years. This survival contrasts conspicuously with that of patients with the far commoner situation of aortic atresia with normally connected great arteries. It is suggested that this difference in longevity is a result of the greater ability of the left ventricl...

    A male newborn infant with hypoplastic left heart and transposition of the great arteries died on the second day of life. The haemodynamic consequences of this malformation are considerably different from those of ordinary hypoplastic left heart syndrome because of pulmonary rather than aortic atresia. In the absence of cross sectional echocardiographic equipment, cardiac catheterisation with angiography is necessary to delineate the anatomical picture. These two conditions have not apparentl...

    Nasal transposition of the inferior rectus (IR) muscle, which is transposed nasally with the insertion parallel to the spiral of Tillaux, could correct excyclotropia. However, as far as we are aware, there have been no reports examining the surgical effects of this procedure in multiple cases. Therefore, we examined the surgical effects of IR nasal transposition in 135 cases with acquired trochlear nerve palsy at Hyogo College of Medicine Hospital, Nishinomiya, Japan. One muscle width of IR nasal transposition corrected an average 5.6° in excyclotorsion, while bilateral IR nasal transposition corrected average 10.9°. This result shows this procedure is accurate quantitatively. Moreover, IR nasal transposition in combination with IR recession or resection can correct vertical deviation and excyclotorsion simultaneously. The results of this study suggest that IR nasal transposition should become first-line treatment for acquired superior oblique palsy. PMID:25945030

  1. Preferential transposition of Drosophila P elements to nearby chromosomal sites.

    1993-02-01

    Two different schemes were used to demonstrate that Drosophila P elements preferentially transpose into genomic regions close to their starting sites. A starting element with weak rosy+ marker gene expression was mobilized from its location in the subtelomeric region of the 1,300-kb Dp1187 minichromosome. Among progeny lines with altered rosy+ expression, a much higher than expected frequency contained new insertions on Dp1187. Terminal deficiencies were also recovered frequently. In a second screen, a rosy(+)-marked element causing a lethal mutation of the cactus gene was mobilized in male and female germlines, and viable revertant chromosomes were recovered that still contained a rosy+ gene due to an intrachromosomal transposition. New transpositions recovered using both methods were mapped between 0 and 128 kb from the starting site. Our results suggested that some mechanism elevates the frequency 43-67-fold with which a P element inserts near its starting site. Local transposition is likely to be useful for enhancing the rate of insertional mutation within predetermined regions of the genome. PMID:8382177

    The primary treatment against macular edema with retinal vein occlusion (RVO) has changed from observation in central RVO (CRVO) and laser photocoagulation in branch RVO (BRVO) to administration of intravitreal agents based on anti-vascular endothelial growth factor (VEGF) or anti-inflammatory strategies. Anti-VEGF treatment such as ranibizumab, bevacizumab, or aflibercept improved vision by 13.9-16.2 letters (best-corrected visual acuity) after 12 months versus baseline in patients with macular edema secondary to CRVO. A long-term study showed that reduced follow-up and fewer retreatments resulted in worsening visual acuity. Intravitreal therapy with anti-inflammatory agents stabilized visual acuity in CRVO. However, increased intraocular pressure and cataract progression were frequently observed. Anti-VEGF agents such as ranibizumab or bevacizumab improved visual acuity by 15.5-18.3 letters in patients with macular edema secondary to BRVO after 12 months. The improved vision remained during the long-term follow-up. There was no significant difference between standard care and intravitreal triamcinolone groups in BRVO, and increased intraocular pressure and cataract progression occurred frequently in the triamcinolone group. Anti-VEGF intravitreal administration resulted in good vision in CRVO and BRVO patients and is employed as a primary therapy. Anti-VEGF therapy requires frequent observations and intravitreal injections to maintain good vision. PMID:26501219

    BACKGROUND: The activity of transposable elements can be regulated by different means. DNA CpG methylation is known to decrease or inhibit transpositional activity of diverse transposons. However, very surprisingly, it was previously shown that CpG methylation of the Sleeping Beauty (SB) transposon significantly enhanced transposition in mouse embryonic stem cells. RESULTS: In order to investigate the unexpected response of SB transposition to CpG methylation, related transposons from the Tc1...

    The LINE-1, or L1, family of interspersed repeated DNA constitutes roughly 10% of the mammalian genome. Its abundance is due to duplicative transposition via an RNA intermediate, L1-encoded proteins, and reverse transcription. Although, in principle, transposition may occur in any cell type, expression and transposition of a full-length functional element in the germ line are necessary to explain the evolutionary genetics of L1. We have found differential expression of L1 protein and RNA in g...

    Full Text Available There is increasing demand world-wide, from government agencies and the private sector for cutting-edge biometric security technology that is difficult to breach but userfriendly at the same time. Some of the older tools, such as fingerprint, retina and iris scanning, and facial recognition software have all been found to have flaws and often viewed negatively because of many cultural and hygienic issues associated with them. Comparatively, mapping veins as a human barcode, a new technology, has many advantages over older technologies. Specifically, reproducing a three-dimensional model of a human vein system is impossible to replicate. Vein map technology is distinctive because of its state-of-the-art sensors are only able to recognize vein patterns if hemoglobin is actively flowing through the person

  8. Neuroanatomical correlates of musical transposition in adolescents: A longitudinal approach

    2013-12-01

    Full Text Available Musicians are trained in melodic transposition, the skill of extracting the pitch interval structure and moving it into different keys. This ability to recognize whether a melody is the same or altered when it is played back in a different key is correlated with both greater neural activation and cortical thickness in bilateral intraparietal sulcus (IPS. Musical training only explains part of this finding, suggesting that the ability to transpose a melody may have innate predispositions. The current study was designed to address this question: Are the anatomical correlates of musical transposition already present in non-musician children at age 14.5? If so, is there any evidence that those traits were already in place at earlier ages? To answer this question, we recruited 47 adolescents (age 14.5 years from a longitudinal study and tested them on a melodic transposition task. These adolescents had already undergone anatomical MRI imaging at the ages of 10, 11.5, 13, and 14.5 years. They were tested on the transposition task at age 14.5. During this visit, we found a relationship between cortical thickness in left IPS and performance on the transposed melody task in the girls and not the boys; no such relationship was observed at any of the earlier ages. Girls reach more advanced staged of pubertal maturation earlier than boys, it is possible that the relationship between cortical thickness in IPS and skill at melodic transposition only emerges once the brain has reached a certain degree of maturity. This claim is supported by a lack of similar sex differences in the adults: the degree of correlation between cortical thickness and performance on the same transposed melody task did not differ between men and women in a previous study. Thus, our results suggest that the relationship between cortical thickness and the ability to transpose a melody is not fixed, and that the effects observed in adults are neither due exclusively to training nor to predisposition.

    Fresh herbs such as basil constitute an important food commodity worldwide. Basil provides considerable culinary and health benefits, but has also been implicated in foodborne illnesses. The naturally occurring bacterial community on basil leaves is currently unknown, so the epiphytic bacterial community was investigated using the culture-independent techniques denaturing gradient gel electrophoresis (DGGE) and next-generation sequencing (NGS). Sample preparation had a major influence on the results from DGGE and NGS: Novosphingobium was the dominant genus for three different basil batches obtained by maceration of basil leaves, while washing of the leaves yielded lower numbers but more variable dominant bacterial genera including Klebsiella, Pantoea, Flavobacterium, Sphingobacterium and Pseudomonas. During storage of basil, bacterial growth and shifts in the bacterial community were observed with DGGE and NGS. Spoilage was not associated with specific bacterial groups and presumably caused by physiological tissue deterioration and visual defects, rather than by bacterial growth. PMID:26308033

    Nutritional elements can affect plant susceptibility to plant pathogens, including Botrytis cinerea. We tested the effect of potassium (K) fertilization on gray mold in sweet basil grown in pots, containers, and soil. Increased K in the irrigation water and in the sweet basil tissue resulted in an exponential decrease in gray mold severity. Potassium supplied to plants by foliar application resulted in a significant decrease in gray mold in plants grown with a low rate of K fertigation. Lower K fertigation resulted in a significant increase in B. cinerea infection under semi-commercial conditions. Gray mold severity in harvested shoots was significantly negatively correlated with K concentration in the irrigation solution, revealing resistance to B. cinerea infection as a result of high K concentration in sweet basil tissue. Gray mold was reduced following K foliar application of the plants. In general, there was no synergy between the fertigation and foliar spray treatments. Proper K fertilization can replace some of the required chemical fungicide treatments and it may be integrated into gray mold management for improved disease suppression. PMID:25760521

    Full Text Available Abstract Background The arterial switch operation (ASO has become the surgical approach of choice for d-transposition of the great arteries (d-TGA. There is, however an increased incidence of midterm and longterm adverse sequelae in some survivors. In order to evaluate operative risk and midterm outcome in this population, we reviewed patients who underwent ASO for TGA at our centre. Methods In this retrospective study 52 consecutive patients with TGA who underwent ASO between 04/1991 and 12/1999 were included. To analyze the predictors for mortality and adverse events (coronary stenoses, distortion of the pulmonary arteries, dilatation of the neoaortic root, and aortic regurgitation, a multivariate analysis was performed. The follow-up time was ranged from 1–10?years (mean 5?years, cumulative 260 patient-years. Results All over mortality rate was 15.4% and was only observed in the early postoperative period till 1994. The predictors for poor operative survival were low APGAR-score, older age at surgery, and necessity of associated surgical procedures. Late re-operations were necessary in 6 patients (13.6% and included a pulmonary artery patch enlargement due to supravalvular stenosis (n?=?3, coronary revascularisation due to coronary stenosis in a coronary anatomy type E, aortic valve replacement due to neoaortic valve regurgitation (n?=?2, and patch-plasty of a pulmonary vein due to obstruction (n?=?1. The dilatation of neoaortic root was not observed in the follow up. Conclusions ASO remains the procedure of choice for TGA with acceptable early and late outcome in terms of overall survival and freedom of reoperation. Although ASO is often complex and may be associated with morbidity, most patients survived without major complications even in a small centre.

    Pyroglyphid house dust mites are the most common cause of allergic symptoms in humans. An assessment was made of the toxicity of basil, Ocimum basilicum L, essential oil, 11 basil oil constituents, seven structurally related compounds, and another 22 previously known basil oil constituents to adult American house dust mites, Dermatophagoides farinae Hughes. The efficacy of four experimental spray formulations containing basil oil (1, 2, 3, and 4% sprays) was also assessed. Results were compared with those of two conventional acaricides benzyl benzoate and N,N-diethyl-3-methylbenzamide. The active principles of basil oil were determined to be citral, alpha-terpineol, and linalool. Citral (24 h LC50, 1.13 microg/cm2) and menthol (1.69 microg/cm2) were the most toxic compounds, followed by methyl eugenol (5.78 microg/cm2). These compounds exhibited toxicity greater than benzyl benzoate (LC50, 8.41 microg/cm2) and N,N-diethyl-3-methylbenzamide (37.67 microg/cm2). Potent toxicity was also observed with eugenol, menthone, spathulenol, alpha-terpineol, nerolidol, zerumbone, and nerol (LC50, 12.52-21.44 microg/cm2). Interestingly, the sesquiterpenoid alpha-humulene, lacking only the carbonyl group present in zerumbone, was significantly less effective than zerumbone, indicating that the alpha,beta-unsaturated carbonyl group of zerumbone is a prerequisite component for toxicity. These compounds were consistently more toxic in closed versus open containers, indicating that their mode of delivery was largely a result of vapor action. Basil oil applied as 3 and 4% sprays provided 97 and 100% mortality against the mites, respectively, whereas permethrin (cis:trans, 25:75) 2.5 g/liter spray treatment resulted in 17% mortality. Our results indicate that practical dust mite control in indoor environments can be achieved by basil oil spray formulations (3 and 4% sprays) as potential contact-action fumigants. PMID:24897858

    Full Text Available There are many anatomical variations presented by the tributaries of the saphenous vein at the saphenous – femoral junction .In anatomical texts, they are plotted as usual tributaries to the femoral vein, presentations that are not found during routine surgical practice. Knowledge of the sapheno- femoral vein junction is imperative for the surgeon when operating the venous system of lower limbs, in order to avoid accidents and prevent intraoperative varicose recurrences. The aim of the present paper is to demonstrate which of the anatomical variations of the arc of the great saphenous vein is shown more often, contributing to the description of the anatomy of the region and its name in the anatomical terminology. The present work is based on experience of one hundred dissections (n = 100 of the femoral inguinal region in human cadavers fixed with formol aqueous solution of 5% v / v, twenty (n = 20 of which were filled with latex via endovascular before its fixation. The basic scheme of the arc of the great saphenous vein receives the following tributaries: the superficial circumflex iliac vein, superficial epigastric vein [subcutaneous abdominal vein], external pudendal veins, accessory vein of the thigh [dorsal thigh], inter saphenous vein [Giacomini vein]. Inter saphenous vein was observed [Giacomini vein] in a large percentage of the sample (66%. On 77% of the cases, a single saphenous trunk was found, 22% of duplication and triplication 1%. Exceptionally small caliber veins reach the common femoral vein on its inner side, draining the pudendal region, may correspond to the third vein pudendal described by Vilanova, or a tributary of the arc that ends in isolation while the rest of the arc remains on the basic disposition. Successful surgery of the saphenous vein arc is based on an optimal anatomical knowledge of the sapheno - femoral junction, its anatomical variations and relationships.

  7. A phase transition in the random transposition random walk

    Our work is motivated by Bourque and Pevzner's (2002) simulation study of the effectiveness of the parsimony method in studying genome rearrangement, and leads to a surprising result about the random transposition walk on the group of permutations on $n$ elements. Consider this walk in continuous time starting at the identity and let $D_t$ be the minimum number of transpositions needed to go back to the identity from the location at time $t$. $D_t$ undergoes a phase transition: the distance $D_{cn/2} \\sim u(c)n$, where $u$ is an explicit function satisfying $u(c)=c/2$ for $c \\le 1$ and $u(c)1$. In other words, the distance to the identity is roughly linear during the subcritical phase, and after critical time $n/2$ it becomes sublinear. In addition, we describe the fluctuations of $D_{cn/2}$ about its mean in each of the three regimes (subcritical, critical and supercritical). The techniques used involve viewing the cycles in the random permutation as a coagulation-fragmentation process and relating the behav...

    Precise measurements of leaf vein traits are an important aspect of plant phenotyping for ecological and genetic research. Here, we present a powerful and user-friendly image analysis tool named phenoVein. It is dedicated to automated segmenting and analyzing of leaf veins in images acquired with different imaging modalities (microscope, macrophotography, etc.), including options for comfortable manual correction. Advanced image filtering emphasizes veins from the background and compensates for local brightness inhomogeneities. The most important traits being calculated are total vein length, vein density, piecewise vein lengths and widths, areole area, and skeleton graph statistics, like the number of branching or ending points. For the determination of vein widths, a model-based vein edge estimation approach has been implemented. Validation was performed for the measurement of vein length, vein width, and vein density of Arabidopsis (Arabidopsis thaliana), proving the reliability of phenoVein. We demonstrate the power of phenoVein on a set of previously described vein structure mutants of Arabidopsis (hemivenata, ondulata3, and asymmetric leaves2-101) compared with wild-type accessions Columbia-0 and Landsberg erecta-0. phenoVein is freely available as open-source software.

    Full Text Available We hypothesized that interrupting the connection between superficial and deep veins of the upper extremity at the elbow for creation of hemodialysis arteriovenous fistulas (AVFs, in addition to adequate dilation of the elbow veins, will reduce the risk of steal syndrome and venous hypertension. In this prospective study over a period of one year, patients who were candidates for creation of elbow AVFs based on Doppler ultrasound findings and physical exa-mination, were enrolled into the study. For creation of AVFs, based on the anatomy of the vessels, side-to-side or end-to-side anastomosis between the brachial artery and either cephalic or median antecubital or basilic veins was performed. In some cases, Gracz AVF was created. For inter-rupting the connection between superficial and deep veins, the perforating vein was either ligated or used for anastomosis. The patients were then followed-up regarding patency rate of the AVF and complications. AVFs were created in 50 patients and the duration of follow-up varied from one to eight months. About 56% (n = 28 of the patients had history of failed AVF or arterio-venous graft and 48% (n = 24 of them had history of insertion of a dual-lumen catheter for hemo-dialysis. Neuromuscular problem (n=1 and infection (n=1 were the observed complications. None of the patients developed steal syndrome or venous hypertension. At the end of the study, 47 AVFs (94% were patent and adequate. Our study suggests that interrupting the connection between the superficial and deep venous systems of the upper extremity can reduce the risk of development of steal syndrome and venous hypertension despite side-to-side anastomosis. These techniques provided acceptable patency rate for elbow AVFs.

    Full Text Available Problem statement: Certain basil essential oils were claimed to have a larvicidal activity towards mosquito's larvae. To test this claim the essential oils of four accessions of basil grown in Sudan were selected and tested for Anopheles larvae. Malaria is the major health problem in the Sudan and the whole country is now considered endemic, with varying degrees, about 35,000 deaths every year due to malaria. Anopheles mosquito is the major vector of malaria disease in Sudan. Search for larvicidal active compound(s is one of several attempts to fine effective and affordable ways to control this mosquito. To determine the toxic effects of basil essential oils extracted by steam distillation against Anopheles larvae. Approach: For the larvicidal bioassay, three concentrations (100, 300, 500 ppm of essential oil solutions of four basil accessions were prepared; 1 mL of ethanol was used to solubilize the oil in water (999 mL. In each concentration of oil solution were inserted 20 larvae (third instars. A set of controls using 0.1% ethanol and untreated sets of larvae in (tap water, were also run for comparison. Data were evaluated through regression analysis, from the regression line; the LC50 values were read. The active ingredients were separated and/ or identified by TLC, IR and GC-MS. Results: Larvicidal activity of the essential oils is varied, lasted for about 9 h and thereafter decreased, LC50 values ranging from 190-300 ppm. Linalool, geraniol and eugenol are active components of basil essential oil against Anopheles larvae. Two accessions were caused 100% mortality at a concentration range 300-500 ppm for 3 h. Conclusion: These results indicated that basil essential oils have larvicidal activity towards Anopheles larvae. Therefore, could be affordable way to control this mosquito.

    Treatment of retinal vein occlusion can be systemic or local. Therapeutic strategies include improved blood supply, treatment of the vision-reducing macular edema by intravitreal injection of inhibitors of vascular endothelial growth factors (VEGF) or corticosteroids and laser photocoagulation for neovascular complications. As long as head-to-head studies comparing steroids and VEGF inhibitors have not been published, none of the available intravitreally injected substances can be given priority. Well-known side effects of intravitreal steroids are cataract formation and ocular hypertension whereas VEGF inhibitors need to be frequently injected. Although therapy for retinal vein occlusion is protracted, initial long-term data indicate that treatment can be terminated in at least half of the patients . Finally, a treatment recommendation according to the current state of data is presented. PMID:26242852

An understanding of his work will help us understand modernism more appropriately. Reference will also be made to opponents who put sight and visuality over and above everything else in man’s effort to acquire knowledge of this world in general.

The first or the main goal is to consider the Modern English poet Basil Bunting’s Objectivist roots according to Mitchell’s paper in 2008. The second goal, which naturally emerges from the first one is to present sound play from Bunting’s own view and define them, regarding to Schott’s contributions in 2003, in a part of his long poem, Briggflatts, which lead to the kind of Aural and visual dancing. Then we will conclude , as Bunting mentions more and more, poetry is only its sound.

    New wave equations are constantly being developed to respond to the increased demand for imaging complex geologic structures. In this study, the authors analyze the efficiency of prestack finite-difference migration with particular focus on data transposition in the two-way splitting algorithm. They presented a tiled data transposition algorithm which achieves good efficiency through greater access coherence. A helical scheme which eliminates the need for data transposition in common-shot migration was also presented. This newly developed algorithm speeds up downward extrapolation by 30 to 40 per cent and produces an image quality that is comparable to non-helical methods. 13 refs., 1 tab., 5 figs.

    Sleeping Beauty (SB) is the most active Tc1/ mariner-type transposon in vertebrates. SB contains two transposase-binding sites (DRs) at the end of each terminal inverted repeat (IR), a feature termed the IR/DR structure. We investigated the involvement of cellular proteins in the regulation of SB transposition. Here, we establish that the DNA-bending, high-mobility group protein, HMGB1 is a host-encoded cofactor of SB transposition. Transposition was severely reduced in mouse cells deficient ...

    Agrobacterium strains harbour insertion sequences, which are known to transpose into genomes as well as into Ti plasmids. In this study we report the inactivation of a transgene due to transposition of the A. tumefaciens insertion sequence IS136. The transposition was discovered following transformation of plant tissues, although the fidelity of the binary vector was confirmed following transformation into Agrobacterium. Such transpositions are rare but can occur and it is thus important to check the fidelity of the binary vector at different times of Agrobacterium growth in order to avoid failure in achieving transgene expression.

The essential features of the thallium scintigrams were marked counterclockwise rotation of the heart with perfusion abnormalities of the inferior wall and apex. Since patients with congenitally-corrected transposition of the great arteries may present with the symptom of chest pain, the diagnosis of transposition of the great arteries should be considered in patients with marked counterclockwise rotation of the heart and segmental perfusion abnormalities on thallium scintigraphy

    The number of medico-legal post-mortem examinations referring to newborns is considerably low: In the case of the Chair and Department of Forensic Medicine of the author's origin, the autopsy rate of such cases is less than 1 %. Even experienced forensic pathologists can find the technical autopsy procedure of a newborn quite difficult. Post-mortem imaging using unenhanced post-mortem computed tomography (PMCT) gives only a limited opportunity to help in conventional autopsy examination. By adding contrast medium (CA) administration, we can significantly expand diagnostic capabilities. However, the post-mortem computed tomography angiography (PMCTA) technique has already been developed mostly in adult death cases (as considerably much more frequent), and no standardised protocol for examination of children exists. The authors present the dual-phase PMCTA examination of a newborn by manual CA administration using the access to umbilical vessels (vein and artery) unveiling transposition of the great arteries (TGA). The results are presented as multiplanar reformatted (MPR) images and three-dimensional (3D) images by volume/surface-rendered reconstructions, giving a contribution towards proving the value of forensic imaging in post-mortem examinations of heart and vascular malformations in newborns.

    The left brachiocephalic vein usually passes superior and anterior to the aortic arch. In rare cases, this vein follows an anomalous course; for example, a circumaortic left brachiocephalic vein. We present the case of a circumaortic left brachiocephalic vein in a 53-year-old male with lung cancer. A multidetector CT showed that the two branches of the left brachiocephalic vein circumscribed the aortic arch. The anterior branch was above and the posterior branch was below the aortic arch. Both branches drained into the superior vena cava.

    Full Text Available This paper is part of larger scope project in which the scientificity of the Gaia theory is analysed, intending to contribute towards a critical appraisal or the role that such a theory might have in biology teaching and in approaching the "environment" transversal theme. The Gaia theory proposes that the biosphere acts as na adaptative control system, keeping the earth in homeostasis. Some authors have proposed that this theory should be incorporated in the school curriculum. In Brazil, it already appears in some biology textbooks. The scientificity of this theory is questioned in this paper, given that its didactical transposition should be suported by a previous demonstration of its scientific nature.

  7. Increased Ac excision (iae): Arabidopsis thaliana mutations affecting Ac transposition

    International Nuclear Information System (INIS)

    The maize transposable element Ac is highly active in the heterologous hosts tobacco and tomato, but shows very much reduced levels of activity in Arabidopsis. A mutagenesis experiment was undertaken with the aim of identifying Arabidopsis host factors responsible for the observed low levels of Ac activity. Seed from a line carrying a single copy of the Ac element inserted into the streptomycin phosphotransferase (SPT) reporter fusion, and which displayed typically low levels of Ac activity, were mutagenized using gamma rays. Nineteen mutants displaying high levels of somatic Ac activity, as judged by their highly variegated phenotypes, were isolated after screening the M2 generation on streptomycin-containing medium. The mutations fall into two complementation groups, iae1 and iae2, are unlinked to the SPT::Ac locus and segregate in a Mendelian fashion. The iae1 mutation is recessive and the iae2 mutation is semi-dominant. The iae1 and iae2 mutants show 550- and 70-fold increases, respectively, in the average number of Ac excision sectors per cotyledon. The IAE1 locus maps to chromosome 2, whereas the SPT::Ac reporter maps to chromosome 3. A molecular study of Ac activity in the iae1 mutant confirmed the very high levels of Ac excision predicted using the phenotypic assay, but revealed only low levels of Ac re-insertion. Analyses of germinal transposition in the iae1 mutant demonstrated an average germinal excision frequency of 3% and a frequency of independent Ac re-insertions following germinal excision of 22%. The iae mutants represents a possible means of improving the efficiency of Ac/Ds transposon tagging systems in Arabidopsis, and will enable the dissection of host involvement in Ac transposition and the mechanisms employed for controlling transposable element activity

    Varicose veins are a common condition attecting approximately 10 million patients in Japan. The main cause of varicose veins is reflux of the saphenous vein, and conventional treatment for several decades was stripping the affected saphenous vein and phlebectomy. Endovenous laser treatment (EVLT) is a less-invasive treatment method in which the saphenous vein is ablated with a laser under local anesthesia. EVLT has been approved by the Japanese Ministry of Health, Labor and Welfare since 2011, and we have performed EVLT on 5,160 legs with saphenous insufficiency with no severe complications including deep vein thrombosis except for one case of arteriovenous fistula. EVLT appears to be a safe, effective treatment option for varicose veins with saphenous insufficiency. PMID:26281654

    Full Text Available The considerable therapeutical problems of persistent infections caused by multidrug-resistant bacterial strains constitute a continuing need to find effective antimicrobial agents. The aim of this study was to demonstrate the activities of basil (Ocimum basilicum L. and rosemary (Rosmarinus officinalis L. essential oils against multidrug- resistant clinical strains of Escherichia coli. A detailed analysis was performed of the resistance of the drug to the strains and their sensitivity to the tested oils. The antibacterial activity of the oils was tested against standard strain Escherichia coli ATCC 25922 as well as 60 other clinical strains of Escherichia coli. The clinical strains were obtained from patients with infections of the respiratory tract, abdominal cavity, urinary tract, skin and from hospital equipment. The inhibition of microbial growth by both essential oils, presented as MIC values, were determined by agar dilution. Susceptibility testing to antibiotics was carried out using disc diffusion. The results showed that both tested essential oils are active against all of the clinical strains from Escherichia coli including extended-spectrum ?-lactamase positive bacteria, but basil oil possesses a higher ability to inhibit growth. These studies may hasten the application of essential oils in the treatment and prevention of emergent resistant strains in nosocomial infections.

    2010-12-01

    Transposition is defined as the interchange of position between two adjacent teeth within the same quadrant of the dental arch. Permanent maxillary canine-premolar transposition is the most commonly observed transposition in the human dentition. Its prevalence is relatively low and its aetiology remains unclear, although it has been associated with genetic factors. It may also be related to a combination of localised factors such as malformation of adjacent teeth, tooth agenesis, retention of the deciduous canine and a history of local trauma. Treatment is selected on an individual case basis after thoroughly considering the overall facial and dental characteristics, duration of treatment, cost, patient preference and the orthodontist\\'s experience. This article provides a case report of maxillary canine transposition in the permanent dentition, successfully managed with orthodontic treatment.

    A kanamycin resistance gene was introduced within the insertion sequence IS231A from Bacillus thuringiensis, and transposition of the element was demonstrated in Escherichia coli. DNA sequencing at the target sites showed that IS231A transposition results in direct repeats of variable lengths (10, 11, and 12 bp). These target sequences resemble the terminal inverted repeats of the transposon Tn4430, which are the preferred natural insertion sites of IS231 in B. thuringiensis.

    A significant bias in sex ratio has been documented for several congenital cardiac malformations. Transposition of the great arteries has been associated with a such a bias but no explanation has been proposed for this bias. We evaluated 95 isolated livebirths with transposition of the great arteries cases referred to the Sicilian Registry of Congenital Malformations from 1991 to 1998. We found a statistically significant male bias of 2.8 and this was significantly associated with both matern...

    Full Text Available Sweet basil (Ocimum basilicum is a popular culinary herbal crop grown for fresh or dry leaf, essential oil and seed markets. Recently, basil was shown to rank highest among species and herbal crops for phenolic compounds, essential oils which are associated with decreasing risks of cancer and aging diseases. The current study aimed to evaluate the potential activity of phenolic, flavonoids and essential oil of basil as antioxidant and anticancer activities by application organic and bio-organic fertilization. A pot experiment was conducted. Basil seeds were grown, with three levels of organic fertilizers (compost in presence or absence of biofertilizer. Growth parameters, pigments content, total phenolics, total flavonoids and antioxidant activity of methanolic plant extract were examined. Application of 50% compost and 50% sand in the presence of biofertilizer resulted in enhancement fresh and dry weights, total phenolics, total flavonoids and pigment content as compared with compost alone. The constituents of essential oils extracted by hydrodistilation of basil leaves were identified by GLC. Eleven components of essential oils were identified. The highest value of antioxidant and anticancer activities were obtained in basil plants grown in 50% and 75% compost treatments in the presence of biofertilizer. These results emphasized the important of bioorganic fertilizers for enhancement the antioxidant activity of phenolics, flavonoids, and essential oils of basil plant extract.

    Full Text Available Effects of the probiotic ‘Protexin', basil essential oil and the antibiotic growth promoter ‘Avilamycin' were studied on the ileum microbial flora of broilers when these substances are used as broiler feed additives. A total of six hundred Arian broilers were divided into 6 treatment groups, with 4 replicates of 25 birds. Treatments have been performed with a plant essential oil at 3 levels (200, 400 and 600 ppm, the probiotic ‘Protexin' (150 ppm, the antibiotic ‘Avilamycin' (150 ppm and a control group with no additives. Birds in different treatments received the same diets during the experimental period. The results showed that the probiotic treatment significantly decreased the total bacteria counts (P0.05. The lowest and highest lactic acid bacteria in ileum were obtained in the control group and in birds receiving 400 ppm basil essential oil, respectively. Moreover, addition of 600 ppm of basil essential oil into diet decreased the number of E. coli colonies as compared to other treatments (P< 0.05. It could be speculated that the basil essential oil and ‘Protexin' could replace the antibiotics, which have been banned to use as growth promoter in animal feeds.

    International Nuclear Information System (INIS)

    The potential for new, small-scale and micro-cogeneration installations in Portugal is very considerable due to the number of potential host buildings. In this work, we discuss the legal framework of the Portuguese energy market, and some modifications to accommodate the Directive, 2004/8/EC are stressed. A practical case of cogeneration is also presented, showing the application of the Annex III (b) and (c) of the Cogeneration Directive. The practical case presented shows that micro CHP can be considered highly efficient, with parameters calculated with the Directive rules. Two main improvements in Portugal's energy policy are important: improvement on the permission to access grid system and improvement on support mechanisms indexing it to PES. The Cogeneration Directive transposition is an excellent opportunity to induce a less restrictive framework for the installation of new cogeneration systems, reducing the technological barriers, namely allowing medium-voltage connection with the grid, and improving the revenues provided from these small cogeneration systems. These modifications can improve significantly the number of potential hosts for small-scale cogeneration systems

  17. Congenitally corrected transposition in the adult: detection by radionuclide angiocardiography

    International Nuclear Information System (INIS)

    Congenitally corrected transposition (CCT) of the great vessels is an uncommon anomaly usually detected in children because of associated severe cardiac malformations. When these are absent, patients may be hemodynamically normal, but associated cardiac abnormalities are usually present in CCT, leading to symptoms in adulthood. When CCT is suggested in an adult, diagnosis by means of ultrasound may be difficult. Radionuclide angiocardiography (RA) is a simple, noninvasive method by which to diagnose CCT. The authors found consistent morphologic scintigraphic results in 13 patients with proved CCT, leading to establishment of reliable diagnostic criteria. In all instances of situs solitus the aorta ascends and descends on the left with vertical orientation. In the case of situs inversus, the aorta ascends and descends on the right with vertical orientation. The authors criteria are independent of the situs and cardiac position, unlike earlier reports by others. They believe images obtained in the anterior projection are sufficient for the study. The practical application of RA study in patient diagnosis is demonstrated, giving special attention to patients referred because of situs solitus and dextrocardia, in which CCT is known to be present in 50% of cases

    Full Text Available The aerial parts essential oils of Ocimum basilicum (Lamiaceae from Togo were steam-distilled and investigated for their percentage composition (GC and GC/MS and in vitro antimicrobial activities. Five oil chemotypes were identified and classified as follows in line with their principal components: estragole type; linalool/estragole type; methyleugenol type; methyleugenol/t-anethole type; t-anethole type. The in vitro microbiological experiments revealed that only the methyleugenol and methyleugenol/t-anethole chemotypes were active against tested fungi and bacteria. Their minimum inhibitory concentrations (MIC ranged from 80 to 150 µl.l-1 and from 200 to 500 µl.l-1 respectively. Likewise, on tested bacteria the MIC varied from 200 µl.l-1 to 400 µl.l-1 and from 250 to 500 µl.l-1 respectively. These findings are supportive of the potential of both basil oil chemotypes for use as active ingredients in natural antibiotic drugs.

  19. Optimisation of microencapsulation of holy basil essential oil in gelatin by response surface methodology.

    Sutaphanit, Polin; Chitprasert, Pakamon

    2014-05-01

    To protect holy basil essential oil (HBEO) from volatilisation and oxidation, microencapsulation by simple coacervation of gelatin was developed. An optimal encapsulating condition obtained from response surface methodology (RSM) was a gelatin concentration of 11.75% (w/v) and an HBEO amount of 31ml, which provided the greatest yield, oil content, and encapsulation efficiency of 98.80%, 66.50%, and 95.41%, respectively. Scanning electron microscope (SEM) revealed that the internal surface of the microcapsule was honeycomb-like networks containing nonhomogeneous distributions of HBEO. Fourier transform infrared spectroscopy (FTIR) indicated that there was no significant interaction between the HBEO and gelatin. Under storage conditions at 60°C for 49days equivalent to 25°C for 18months, small decreases in the HBEO retention rate and the antioxidant activity were observed. Thus, the microencapsulated formulation has potential to be applied to other volatile compounds. PMID:24360456

  20. Idiopathic Bilateral External Jugular Vein Thrombosis

    2015-01-01

    Patient: Male, 21 Final Diagnosis: Idiopathic bilateral external jugular vein thrombosis Symptoms: Face engorgement • neck swelling Medication: — Clinical Procedure: None Specialty: Hematology Objective: Unknown ethiology Background: Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow’s triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. Case Report: This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely. Conclusions: Bilateral idiopathic external jugular veins thrombosis is extremely rare and can be an indicator of early malignancy or hidden infection. While previous reports in the literature have associated jugular vein thrombosis with malignancy, the present case shows that external jugular vein thrombosis can also be found in persons without malignancy.

  2. Transposition bursts during analysis of secondary mutations in the unstable lines of Drosophila melanogaster

    International Nuclear Information System (INIS)

    The article deals with realization of transposition memory discovered earlier at cut locus and in MDG4. The unstable line cmMR17 ctMRpN17, a derivative of ctMR2 line, was used. It has high frequency of double cm+ct+ revertants and secondary cmMRctMRpN mutants. Such mutant transitions were observed in the line five times. Mutation ctMRpN17 was caused by the insertion at cut locus of MDG4 with another mobile element, jockey. In situ hybridization showed that the transitions from mutational condition to normal are strongly correlated with the excision of MDG4 and jockey from 7B3-4 region of cut locus and their repeated insertion into it. The analysis of distribution of MDG1, MDG2, MDG3, and jockey in the X chromosomes of the revertant larvae and secondary mutants showed that not only transpositions of MDG4 and jockey but also simultaneous multiple migration of all the tested mobile elements take place with their complete stability in the absence of mutational transitions. Therefore, the transposition memory in this system of genetic instability is realized in the process of transposition bursts, but does not lead to isolated repeated transpositions of MDG4

  3. Myocardial imaging in patients with transposition of the great arteries

    International Nuclear Information System (INIS)

    Thallium-201 myocardial imaging was performed in 21 patients with transposition of the great arteries (TGA). In the 13 pa tients with preoperative TGA, it was possible to differentiate TGA with the intact ventricular septum from TGA with associated anomalies such as patent ductus arteriosus or ventricular septal defect, and also TGA with pulmonary hypertension or pulmonary stenosis from TGA without them by evaluating the degree of thallium uptake in the free wall of the pulmonary ventricle (anatomical left ventricle). The degree of thallium uptake was well correlated with systolic pressure of the pulmonary ventricle (r = 0.98). In the 13 patients with postoperative TGA, it was less correlated with the pulmonary ventricular systolic pressure (r = 0.83). Four cases sequentially studied showed a marked decrease in thallium uptake in the pulmonary ventricle 10 to 16 months after Rastelli operation. But the corrected thallium uptake (thallium activity / ventricular systolic pressure) was more increased compared with the uptake of the systemic ventricle after the surgery. This was probably related to a decrease of the pressure load to the pulmonary ventricle following the surgery and to the fact that there should be some delay of a decrease of the ventricular mass. An increased lung uptake of thallium was noted in the cases of tricuspid regurgitation after Mustard operation, but the degree of regurgitation was not clearly correlated with the increase of thallium uptake in the lung. In five cases after Rastelli operation, one patient showed a high degree of thallium uptake of the pulmonary ventricle (anatomical right ventricle), and the conduit valve calcification and severe pulmonary stenosis were confirmed by cardiac catheterization and angiography. Thus myocardial imaging provides a reliable mean for the qualitative and quantitative assessment of TGA before and after operation. (J.P.N.)

  5. The roles of a flavone-6-hydroxylase and 7-O-demethylation in the flavone biosynthetic network of sweet basil.

    Science.gov (United States)

    Berim, Anna; Gang, David R

    2013-01-18

    Lipophilic flavonoids found in the Lamiaceae exhibit unusual 6- and 8-hydroxylations whose enzymatic basis is unknown. We show that crude protein extracts from peltate trichomes of sweet basil (Ocimum basilicum L.) cultivars readily hydroxylate position 6 of 7-O-methylated apigenin but not apigenin itself. The responsible protein was identified as a P450 monooxygenase from the CYP82 family, a family not previously reported to be involved in flavonoid metabolism. This enzyme prefers flavones but also accepts flavanones in vitro and requires a 5-hydroxyl in addition to a 7-methoxyl residue on the substrate. A peppermint (Mentha × piperita L.) homolog displayed identical substrate requirements, suggesting that early 7-O-methylation of flavones might be common in the Lamiaceae. This hypothesis is further substantiated by the pioneering discovery of 2-oxoglutarate-dependent flavone demethylase activity in basil, which explains the accumulation of 7-O-demethylated flavone nevadensin.

  6. Study on Corrosion Inhibition Efficiency of Stem Alkaloid Extract of Different Varieties of Holy Basil on Aluminium in HCl Solution

    International Nuclear Information System (INIS)

    Corrosion inhibition efficiencies of holy basil on Al in HCl solution were studied by weight loss and thermometric methods in presence and in absence of stem extract of three different varieties of holy basil viz. ocimum basilicum (EB), ocimum canum (EC) and ocimum sanctum (ES). Inhibition efficiency increases with the increasing concentration of stem extract and decreases with increases in acid strength. Results show that all varieties under study are good corrosion inhibitors, among which, EB is most effective. Maximum inhibition efficiency was found 97.09% in 0.5N HCl solution with 0.6% stem extract. The Langmuir adsorption isotherm indicates that surface coverage also increases with increasing in the concentration of extract of stem in HCl solution

    International Nuclear Information System (INIS)

    Congenitally corrected transposition of great arteries (CCTGA) is a rare congenital disease first described by Von Rokitansky in 1875. Transposition of the great arteries comprises 2.6-7.8% of all cases of congenital heart disease, and if uncorrected, is commonly fatal in first year of life. Patients with corrected transposition of the great arteries without associated defects may remain undiagnosed until adult life. Symptoms occur rarely before the fourth and fifth decades, when rhythm disturbance, left atrioventricular valve regurgitation and moderately impaired systemic ventricular function cause congestive cardiac failure. We report here a case of drug overdose with ischemic symptoms and CCTGA without associated anomalies in a 40-year-old male. (author)

    Full Text Available Anterior transposition of the ulnar nerve is widely implemented for treatment of cubital tunnel ?syndrome. However, preservation of the extrinsic blood supply of the ?ulnar nerve may result in better clinical outcomes. Fourteen patients with cubital tunnel ?syndrome, 11 ?men and 3 women, were treated by anterior subcutaneous transposition of the ulnar nerve. The extrinsic blood supply of the ulnar nerve was ?preserved. The average age at the time of operation was 33 years. The average follow-up period was 44 months. Post-operative outcome assessment by an independent examiner was based on the modified Bishop rating system. Nine patients had excellent or good outcomes. Five patients had a fair outcome.

    Full Text Available Allah Haafiz1, Jonathan L Williams2, Joel M Andres1, Don A Novak11Pediatric Gastroenterology, Hepatology; 2Department of Pediatric Radiology, University of Florida College of Medicine, Gainesville, FL, USAAbstract: A 6-day-old, known to have transposition of the great vessels, received care in the neonatal intensive care unit at a tertiary care center. A computed tomography scan was performed for abdominal distention and upper gastrointestinal bleeding, which revealed a “mass lesion” in the left liver lobe. Analysis of antecedent events and the clinical and laboratory course uncovered an iatrogenic etiology and pathogenesis of the lesion. As the nature of the lesion was clarified, no specific therapy was required. This case is presented to show a serious yet preventable complication of a commonly performed procedure.Keywords: portal vein thrombosis, liver mass, umbilical venous catheter

    2011-08-01

    Biometric identification is an emerging technology that can solve security problems in our networked society. A reliable and robust personal verification approach using dorsal hand vein patterns is proposed in this paper. The characteristic of the approach needs less computational and memory requirements and has a higher recognition accuracy. In our work, the near-infrared charge-coupled device (CCD) camera is adopted as an input device for capturing dorsal hand vein images, it has the advantages of the low-cost and noncontact imaging. In the proposed approach, two finger-peaks are automatically selected as the datum points to define the region of interest (ROI) in the dorsal hand vein images. The modified two-directional two-dimensional principal component analysis, which performs an alternate two-dimensional PCA (2DPCA) in the column direction of images in the 2DPCA subspace, is proposed to exploit the correlation of vein features inside the ROI between images. The major advantage of the proposed method is that it requires fewer coefficients for efficient dorsal hand vein image representation and recognition. The experimental results on our large dorsal hand vein database show that the presented schema achieves promising performance (false reject rate: 0.97% and false acceptance rate: 0.05%) and is feasible for dorsal hand vein recognition.

    1997-12-01

    Routine preoperative investigation of chronic venous insufficiency of the lower limbs with echo-Doppler has brought to light the presence of reflux into the gastrocnemius veins in almost 30% of the patients. Surgical treatment to stop this reflux consists in dividing the gastrocnemius vein flush to the popliteal vein. Early postoperative investigation of patients operated on in this way, who are symptomless and with no residual varices, has revealed the presence of persistent, symptomless, postoperative reflux into the gastrocnemius veins. One hundred and six patients were checked six months postoperatively by Duplex Doppler scanning. On the basis of the anatomical and functional findings, postoperative incompetence of the gastrocnemius veins could be classified into several types according to the cause: 1. Persistence of a complete and incompetent gastrocnemius vein, probably missed at operation: 16 patients (15%). 2. Neoangiogenesis: 11 patients (10%). 3. Persistence of an incompetent lower gastrocnemius perforating vein: 17 patients (16%). Thus, echography has revealed that in 44 lower limbs out of 106 (42%) in which the gastrocnemius veins were operated on, six months postoperatively evidence of reflux into the gastrocnemius venous network was present. All these patients were asymptomatic. In a sub-group of 48 lower limbs which had an interval Doppler check at 2 months: 6 already showed a reflux (12.5%), in 11 the gastrocnemius reflux appeared between the second and the sixth months (23%), 31 showed no reflux at 6 months (64.5%). From these findings, certain rules on the surgery of the gastrocnemius veins have been drawn up. PMID:9479603

  15. A reappraisal of saphenous vein grafting

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Autologous saphenous vein grafting has been broadly used as a bypass conduit, interposition graft, and patch graft in a variety of operations in cardiac, thoracic, neurovascular, general vascular, vascular access, and urology surgeries, since they are superior to prosthetic veins. Modified saphenous vein grafts (SVG, including spiral and cylindrical grafts, and vein cuffs or patches, are employed in vascular revascularization to satisfy the large size of the receipt vessels or to obtain a better patency. A loop SVG helps flap survival in a muscle flap transfer in plastic and reconstructive surgery. For dialysis or transfusion purposes, a straight or loop arteriovenous fistula created in the forearm or the thigh with an SVG has acceptable patency. The saphenous vein has even been used as a stent cover to minimize the potential complications of standard angioplasty technique. However, the use of saphenous vein grafting is now largely diminished in treating cerebrovascular disorders, superior vena cava syndrome, and visceral revascularization due to the introduction of angioplasty and stenting techniques. The SVG remains the preferable biomaterial in coronary artery bypass, coronary ostioplasty, free flap transfer, and surgical treatment of Peyronie disease. Implications associated with saphenous vein grafting in vascular access surgery for the purpose of dialysis and chemotherapy are considerable. Vascular cuffs and patches have been developed as an important and effective means of enhancing the patency rates of the grafts by linking the synthetic material to the receipt vessel. In addition, saphenous veins can be a cell source for tissue engineering. We review the versatile roles that saphenous vein grafting has played as well as its current status in therapy.

  16. Reconstruction of rectal sphincter by transposition of gluteus muscle for fetal incontinence.

    Science.gov (United States)

    Chen, Y L; Zhang, X H

    1987-01-01

    Many remedial operations have been described for fecal incontinence. We describe a bilateral gluteus muscle transposition to encircle the rectum with striated muscle. This procedure positions a voluntary muscle around the rectum to produce volitional rectal closure, the opposite direction pulling produces a kinking closure of the rectum, and the newly accentuated anorectal angle also facilitates continence. In 6 incontinent patients, 3 were normalized by this procedure, 1 was improved, and 2 had delayed improvement secondary to the development of a fecaloma. Gluteus muscle transposition may be a useful secondary procedure in that patient with muscle dysfunction deficiency fecal incontinence. PMID:3819996

  17. Understanding how the V(D)J recombinase catalyzes transesterification: distinctions between DNA cleavage and transposition

    OpenAIRE

    Lu, Catherine P.; Posey, Jennifer E; David B. Roth

    2008-01-01

    The Rag1 and Rag2 proteins initiate V(D)J recombination by introducing site-specific DNA double-strand breaks. Cleavage occurs by nicking one DNA strand, followed by a one-step transesterification reaction that forms a DNA hairpin structure. A similar reaction allows Rag transposition, in which the 3?-OH groups produced by Rag cleavage are joined to target DNA. The Rag1 active site DDE triad clearly plays a catalytic role in both cleavage and transposition, but no other residues in Rag1 respo...

    This paper is concerned with nonuniform power line modelling. It deals with the resonance effects produced by conductor transposition in long overhead three-phase lines. A frequency- domain analysis is conducted showing that the modal propagation parameters characterising the transmission line structure exhibit a repetitive resonant behaviour for frequencies such that the overall transposition cycle length gets close to an integer multiple of one half wavelength. Consideration of these resonance phenomena is of major importance and should be taken into account in a variety of situations, for example, in power line carrier communications and line transient studies.

    A descriptive case report of the labour and delivery management of a 28-year-old woman who presented with congenitally corrected transposition of great arteries, dextrocardia, systemic ventricular dysfunction and junctional tachycardia. Patients with congenitally corrected transposition have a thin-walled morphological right ventricle as the systemic circulatory pump. The stress of increased cardiac output can lead to congestive heart failure, systemic atrioventricular valve regurgitation and arrhythmias. We used minimally invasive continuous cardiac output monitoring, fluid balance optimization and good maternal pain control to prevent decompensation and achieve vaginal delivery with a good maternal and neonatal outcome.

    Recently it has been shown that in patients with transposition of the great arteries the isometric relaxation time of the left ventricle could be negative in the presence of normal pulmonary artery pressure. In order to find an explanation for this apparently paradoxical situation, it was decided to evaluate the importance of the delay of closure of the pulmonary valve in 15 patients with transposition of the great arteries. This delay is called the hang-out time. The hang-out time was found ...

    Full Text Available Mesenteric vein thrombosis is an uncommon complication following laparoscopic surgery. A review of the literature has shown that there is a higher incidence of thrombosis following laparoscopic bariatric procedures, including the gastric sleeve procedure and roux-en-y gastric bypass surgery. Additionally, pylephlebitis, thrombosis of portal or mesenteric veins, has been described following perforated appendicitis. However no report has described mesenteric vein thrombosis following laparoscopy for nonperforated appendicitis in the pediatric population. The cause of this thrombosis is hypothesized to be secondary to venous stasis secondary to insufflation during laparoscopy.

    Full Text Available With an increasing emphasis on security, automated personal identification using hand vein biometric feature is becoming a very active topic in both research and practical applications. The objective of this work is to present a biometric authentication system for high security physical access control based on hand vein pattern. Hand vein biometric is selected, as it is foolproof, offers higher security and reliable for identification.The feature extraction stage consists of removal of the noise inherent using various filtering techniques and extraction of the most discriminating information present in the images using Discrete Wavelet Transform and Adaptive Thresholding techniques. The proposed recognition system makes use of hausdorff distance as matching parameter. The biometric system developed was tested on WASET hand vein image database of Chinese Academy of Sciences Institute of Automation is used and the system is implemented in MATLAB. The proposed approach found to report higher verification accuracy of 99.5%.

    AIM: To study the safety, effectiveness and diagnostic value of transvenous forceps biopsy of the liver in 54 patients with coagulopathy, gross ascites or morbid obesity and suspected liver disease in whom percutaneous liver biopsy was contraindicated. MATERIAL AND METHODS: Forceps biopsy of the liver via the femoral vein was attempted in 54 adult patients with advanced liver disease of unknown aetiology who had coagulation disorders (41 cases), gross ascites (11 cases) or morbid obesity (two cases). In each patient two to six biopsies (average four) were taken using a radial jaw forceps inserted via the right or left femoral vein. RESULTS: The procedure was successful in 53 cases. Hepatic vein catheterization failed in one patient. Adequate liver tissue for diagnosis was obtained in 84% of cases. One patient developed delayed haemorrhage at 12 h from a capsular leak that was undetected during the biopsy procedure. This patient required blood transfusions and laparotomy to control bleeding. There were no deaths in the 53 patients studied. Transient minor chest and shoulder pain was encountered during sheath insertion into a hepatic vein in 23 patients. Three patients developed a femoral vein haematoma, which resolved with conservative treatment. CONCLUSION: Transvenous liver biopsy via the femoral vein is another safe, effective, simple alternative technique of biopsy when the percutaneous route is contraindicated

    Full Text Available ?Abstract?Objective: To discuss the effect of coupled external fixator and skin flap transposition on exposed and nonunion bones. Methods: The data of 12 cases of infected nonunion and exposed bone following open fracture treated in our hospital during the period of March 1998 to June 2008 were analysed. There were 10 male patients, 2 female patients, whose age were between 19-52 years and averaged 28 years. There were 10 tibial fractures and 2 femoral fractures. The course of diseases lasted for 12-39 months with the mean period of 19 months. All the cases were treated by the coupled external fixator and skin flap transposition. Results: Primary healing were achieved in 10 cases and delayed healing in 2 cases in whom the tibia was exposed due to soft tissue defect and hence local flap transposition was performed. All the 12 cases had bony union within 6-12 months after operation with the average time of 8 months. They were followed up for 1-3 years and all fractures healed up with good function and no infection recurrence. Conclusion: The coupled external fixator and skin flap transposition therapy have shown optimal effects on treating infected, exposed and nonunion bones.

Quando ocorre persistência da veia ciática, esta pode se comunicar com a veia safena parva ou com a veia poplítea durante seu percurso, anastomosando-se com a veia perfurante superior e com a veia circunflexa medial do fêmur. OBJETIVO: Relatar o caso da persistência bilateral de veia ciática nos membros inferiores, comparando à literatura. MÉTODOS: Foram dissecados 32 membros inferiores de 16 cadáveres formolizados no Laboratório de Anatomia pela Disciplina de Anatomia Topográfica da Faculdade de Medicina da Universidade de Santo Amaro (Unisa), durante 2006 e 2007, observando-se em 2 membros inferiores de um único cadáver, a presença de veia ciática. RESULTADOS: No membro inferior esquerdo de um cadáver que apresentou a anomalia bilateralmente, a veia media 37 cm, tinha origem na região da veia poplítea, acompanhava o nervo ciático, perfurava o músculo adutor magno e desembocava na veia femoral profunda. No membro inferior direito, ela media 36 cm, originava-se recebendo as veias do compartimento tibial anterior, acompanhava o nervo ciático, perfurava o músculo adutor magno e desembocava na veia ilíaca interna. CONCLUSÃO: As variações anatômicas do sistema venoso do membro inferior são as mais prevalentes. A persistência da veia ciática pode causar insuficiência venosa crônica no membro inferior e, dessa forma, deve ser investigada para uma melhor conduta clínica ou cirúrgica.

In vascular embryogenesis, there is a differentiation of the angioblasts in a primitive vascular plexus, with posterior remodeling and expansion. Consequently, anomalies may occur during this proces [...] s. When there is persistence of the sciatic vein, it may communicate with the small saphenous vein or with the popliteal vein during its route, being anastomosed to the superior perforating vein and to the medial circumflex femoral vein. OBJECTIVE: To report a case of bilateral persistent sciatic vein on the lower limbs in comparison to the literature. METHODS: Thirty-two lower limbs from 16 corpses preserved in formaldehyde were dissected at the Laboratory of Anatomy of the discipline of Topographic Anatomy of the Medical School of Universidade Santo Amaro (Unisa), during 2006 and 2007, and the sciatic vein was observed in 2 lower limbs of one single corpse. RESULTS: On the left lower limb of a corpse that presented bilateral anomaly, the vein had 37 cm, emerging on the popliteal vein, accompanying the sciatic nerve, perforating the long adductor muscle and leading into the deep femoral vein. On the right lower limb, it measured 36 cm, emerged receiving the veins of the anterior tibial compartment, accompanied the sciatic nerve, perforated the long adductor muscle and led into the internal iliac vein. CONCLUSION: The anatomical variations of the lower limb venous system are the most common ones. The persistent sciatic vein may cause chronic venous failure in the lower limbs and, in this manner, must be investigated aiming at a better clinical or surgical management.

    During the hydraulic fracturing, the pressurized fluid creates new fractures and reactivates existing natural fractures forming a highly conductive Stimulated Reservoir Volume (SRV) around the borehole. We extend the previous work on Lyons sandstone and pyrophyllite to anisotropic shale from the Wolfcamp formation. We divide the rock anisotropy into two groups: a) conventional and b) unconventional (shaly) anisotropy. X-ray Computed Tomography (CT), compressional velocity anisotropy, and SEM analysis are used to identify three causes of anisotropy: bedding planes, clay lamination, and calcite veins. Calcite vein is a subsequently filled with calcite bonded weakly to the matrix. Velocity anisotropy and visual observations demonstrate the calcite filled veins to be mostly subparallel to the fabric direction. Brazilian tests are carried out to observe the fracture initiation and propagation under tension. High speed photography (frame rate 300,000 frame/sec) was used to capture the failure. Strain gauges and Acoustic Emission (AE) sensors recorded the deformation leading up to and during failure. SEM imaging and surface profilometry were employed to study the post-failure fracture system and failed surface topology. Fracture permeability was measured as a function of effective stress. Brazilian tests on small disks containing a centered single vein revealed the shear strength of the veins. We interpret the strain data and number, frequency, and amplitude of AE events which are correlated well with the observed fracture process zone, surface roughness, and permeability. The unpropped fracture has enhanced permeability by two orders of magnitude. The observed anisotropic tensile failure seems to have a universal trend with a minimum strength occurring at 15o orientation with respect to the loading axis. The veins at 15o orientation with respect to the loading axis were easily activated at 30% of the original failure load. The measured strength of the vein is as low as 6% of the matrix. Surface roughness measurements show the vein to be as rough as the main tensile fracture in the matrix. The observations suggest that fracking through a deviated well reduces the breakdown pressure significantly and can activate a large number of veins with enhanced conductivity without the need for excessive proppant injection.

    Full Text Available Las venas superficiales de la fosa cubital, constituyen uno de los sitios más importantes de punción venosa. La disposición de estas venas presenta numerosas variaciones. Su anatomía no ha sido estudiada aplicando los avances tecnológicos en el campo de la medicina, como la tomografía computada heli [...] coidal. Fueron analizadas mediante tomografía axial computada helicoidal, las formaciones venosas de la fosa cubital en 60 individuos chilenos de ambos sexos, de edades entre 10 y 86 años, de la IX Región de La Araucanía, Chile. El estudio fue realizado en un tomógrafo General Electric, modelo CT/e, perteneciente al Centro de Imagenología del Hospital del Trabajador, Temuco, Chile, en individuos ambulatorios. Basados en la clasificación de del Sol et al. (1988) para las formaciones venosas de la fosa cubital, se obtuvo los siguientes resultados: Tipo I (46,7%), la vena cefálica del antebrazo (VCA), se divide en vena mediana basílica (VMB) y vena mediana cefálica (VMC), las que se unen a la vena basílica del antebrazo (VBA) y vena cefálica del accesoria del antebrazo (VCAA), respectivamente. Tipo II (13,3%), la VCA originó la vena mediana del codo (VMCo), que se une a la VBA. Tipo III (20%), no existe comunicación entre la VBA y VCA a nivel de la fosa cubital. Tipo IV (8,3%), la VCA drenaba en la VBA. Tipo V (11,7%). Otras disposiciones, donde se incluye la "M" clásica, que resulta de la división de la vena mediana del antebrazo. La utilización de la VMC o de la VCA, se recomienda ya que previene los riesgos de punción de otras estructuras anatómicas importantes como el ramo anterior del nervio cutáneo antebraquial medial. Abstract in english The superficial veins of the cubital fossa, is one of the most important sites of venipunctures. There are many variations in the arrangement of these veins. Their anatomy has not been studied using technology available in the field of medicine such, as helical computed tomography. The vein formatio [...] n of the cubital fossa in 60 Chilean subjects of both sexes, between 10 and 86 years of age of the IX Region of Araucania, Chile, were analyzed by helical computed tomography. The study was realized on a General Electric scanner, model CT / e, belonging to the Imaging Center of the Hospital del Trabajador, Temuco, Chile, in ambulatory subjects. Based on the classification of del Sol et al. (1988) for the vein formation of the cubital fossa, we obtained the following results: Type I (46.7%), the cephalic vein of forearm (CVF), is divided into median basilic vein (MBV) and median cephalic vein (MCV), then anastomosis the basilic vein of forearm (BVF) and cephalic vein accessory (CVA), respectively. Type II (13.3%), the CVA originates at the median cubital vein (MCuV), which anastomoses to the BVF. Type III (20%), there is no communication between BVF and CVF at the cubital fossa. Type IV (8.3%), CVF drains into the BVF. Type V (11.7%) - Other disposition, which include the "M" classical, resulting from the division of the median antebrachial vein. Using the MCV or CVF, is recommended, since there are risks of puncture of other important anatomical structures such as the anterior branch of the medial antebrachial cutaneous nerve.

    By analytical theory and computer simulation the expected evolutionary dynamics of P transposable element spread in an infinite population are investigated. The analysis is based on the assumption that, unlike transposable elements which move via RNA intermediates, the harmful effects of P elements arise primarily in the act of transposition, and that this causes their evolutionary dynamics to be unusual. It is suggested that a situation of transposition-selection balance will be superceded b...

    2008-05-01

    The treatment of central retinal vein occlusion (CRVO) is still a subject of debate. Medical therapy efforts, as well as retinal laser photocoagulation, have mostly dealt with management of the sequelae of CRVO, and have shown limited success in improving visual acuity. The unsatisfactory results of such therapeutic efforts led to the development of new treatment strategies focused on the surgical treatment of the occluded retinal vein. The purpose of this review is to summarize the outcomes of commonly reported surgical treatment strategies and to review different opinions on the various surgical approaches to the treatment of CRVO.

    The piggyBac (PB) transposon is one of the most useful transposable elements, and has been successfully used for genetic manipulation in more than a dozen species. However, the efficiency of PB-mediated transposition is still insufficient for many purposes. Here, we present a strategy to enhance transposition efficiency using a fusion of transcription activator-like effector (TALE) and the PB transposase (PBase). The results demonstrate that the TALE-PBase fusion protein which is engineered in this study can produce a significantly improved stable transposition efficiency of up to 63.9%, which is at least 7 times higher than the current transposition efficiency in silkworm. Moreover, the average number of transgene-positive individuals increased up to 5.7-fold, with each positive brood containing an average of 18.1 transgenic silkworms. Finally, we demonstrate that TALE-PBase fusion-mediated PB transposition presents a new insertional preference compared with original insertional preference. This method shows a great potential and value for insertional therapy of many genetic diseases. In conclusion, this new and powerful transposition technology will efficiently promote genetic manipulation studies in both invertebrates and vertebrates. PMID:26608076

O objetivo deste trabalho foi avaliar a produção de biomassa de manjericão sob duas ou três fileiras no canteiro, consorcia [...] do ou não com alface. O manjericão e a alface foram alocados no campo em experimento conjunto, sendo constituídos cinco tratamentos da seguinte forma: duas fileiras solteiras de manjericão (M2) espaçadas de 0,50 m; três fileiras solteiras de manjericão espaçadas de 0,33 m (M3); quatro fileiras solteiras de alface espaçadas de 0,25 m (A4); duas fileiras solteiras de manjericão consorciadas com quatro fileiras de alface (M2A4) e três fileiras de manjericão consorciada com quatro fileiras de alface (M3A4). O delineamento utilizado foi em blocos casualizados, com oito repetições. As plantas de alface foram colhidas aos 48 dias após o transplantio e as de manjericão, em duas épocas, aos 96 e 113 dias após o transplantio (DAT). O consórcio não influenciou as áreas foliares nem as produções de folhas ou inflorescências do manjericão nem de cabeças comerciais ou não-comerciais da alface. No entanto, quanto ao arranjo de plantas, na segunda época de colheita, as plantas de manjericão cultivadas sob duas fileiras tiveram maior área foliar (2.076,99 cm² planta-1) e maior massa fresca de folhas (5.012,53 kg ha-1). Considerando-se que os valores da Razão de Área Equivalente - RAE na primeira e segunda colheita do manjericão foram maiores que 1,0, conclui-se que o consórcio manjericão com alface é viável. Recomenda-se o arranjo de três fileiras de manjericão alternadas com quatro fileiras de alface, e colheita aos 96 DAT, por ter tido RAE de 2,01. Abstract in english Ocimum basilicum L. (Lamiaceae) is used commercially as flavoring or seasoning that was prepared with its green and aromatic leaves, which can be used fresh or dried. The aim of this work was to evaluate yield of biomass of basil under two or three rows per plot, intercropped or not with lettuce. Ba [...] sil and lettuce were planted at field in joined experiment, which established five treatments: two rows of basil in monocrop system (M2) spaced 0.50 m; three rows of basil in monocrop system spaced 0.33 m (M3); four rows of lettuce in monocrop system spaced 0.25 m (A4); two rows of basil in monocrop system and intercropped with four rows of lettuce (M2A4) and three rows of basil intercropped with four rows of lettuce (M3A4). Used design was randomized blocks with eight replications. Lettuce plants were harvested on 48 days after transplanting and basil plants were harvested in two dates, on 96 and on 113 days after transplanting (DAT). Intercrop did not influence on foliar area neither on yields of leaves of inflorescences of basil neither on commercial or non-commercial lettuce heads. Although, regarding plant arrangement, on second harvest date, basil plants that were cultivated under two rows had the greatest foliar area (2,076.99 cm² plant-1) and the greatest fresh masses of leaves (5,012.53 kg ha-1). Considering that the values of Equivalent Area Ration in the first and the second harvest of basil were higher than 1.0. It was concluded that to intercrop basil with lettuce is viable. It is recommended the arrangement of three rows of basil alternated with four rows of lettuce, with harvested at 96 DAT, because it had EAR of 2.01.

  11. Analysis of the Superconducting Cable Transposition in Low Resistance CICC Joint

    Science.gov (United States)

    Zhu, You-hua

    2000-08-01

    In an integrated structure low resistance CICC joint, current is conducted by outer cable strands coming into touch with the conductive Cu sole. So it is an important condition for satisfying joint performance that each strand of the cable inside the joint is able to come to the outermost by transposition. This paper presents analysis, calculation and figures for the strand transposition. According to the twist procedures of the superconducting cable, the author computed the actual pitch of each stage cable, consecutively computed the projection of each stage cable on the axis of the cable (z axis) and the corresponding twist angle as the z coordinate changes, which is then drawn by AutoCAD. From the results shown in the figures, the minimal cable length, which enables each strand to transpose almost equally to the outermost of the cable in such a length, can be determined as the optimal joint length.

  12. Congenitally corrected transposition of the great arteries associated with the pre-excitation syndrome

    International Nuclear Information System (INIS)

    A case with congenitally corrected transposition of the great arteries associated with the pre-excitation syndrome is presented. A gated-blood-pool study and Tl-201 myocardial imaging were performed using SPECT. The tomographic gated-blood-pool images showed the shapes of the right ventricle (RV) and left ventricle (LV), i.e., anatomically LV and RV respectively, to be reversed from that of normal patients. The relationships of the great vessels and ventricles also were easily visualized. RV hypertrophy (anatomical LV) was visualized on the Tl-201 images. Phase analysis showed the earliest excitation was in the anteroseptal region near the base of the LV, which was consistent with the site of the accessory conduction pathway. The gated-blood-pool and Tl-201 tomographic studies were helpful for demonstrating the corrected transposition of the great arteries and the pre-excitation syndrome

    Mortality before surgery must be taken into account when comparing the surgical mortality of atrial redirection procedures (Mustard's or Senning's operation) and the arterial switch operation for patients with complete transposition. This is because the switch operation is usually performed within the neonatal period or early infancy but Mustard's or Senning's operation usually after 4 months of age. The outcome of balloon atrial septostomy was therefore assessed in all 102 infants with trans...

    2013-10-01

    Full Text Available The results of ecological restoration techniques can be monitored through biological indicators of soil quality such as the leaf litter arthropod fauna. This study aimed to determine the immediate effect of brushwood transposition transferred from an area of native vegetation to a disturbed area, on the leaf litter arthropod fauna in a degraded cerrado area. The arthropod fauna of four areas was compared: a degraded area with signal grass, two experimental brushwood transposition areas, with and without castor oil plants, and an area of native cerrado. In total, 7,660 individuals belonging to 23 taxa were sampled. Acari and Collembola were the most abundant taxa in all studied areas, followed by Coleoptera, Diptera, Hemiptera, Hymenoptera, and Symphyla. The brushwood transposition area without castor oil plants had the lowest abundance and dominance and the highest diversity of all areas, providing evidence of changes in the soil community. Conversely, the results showed that the presence of castor oil plants hampered early succession, negatively affecting ecological restoration in this area.

    Haplotype-resolved genome sequencing enables the accurate interpretation of medically relevant genetic variation, deep inferences regarding population history and non-invasive prediction of fetal genomes. We describe an approach for genome-wide haplotyping based on contiguity-preserving transposition (CPT-seq) and combinatorial indexing. Tn5 transposition is used to modify DNA with adaptor and index sequences while preserving contiguity. After DNA dilution and compartmentalization, the transposase is removed, resolving the DNA into individually indexed libraries. The libraries in each compartment, enriched for neighboring genomic elements, are further indexed via PCR. Combinatorial 96-plex indexing at both the transposition and PCR stage enables the construction of phased synthetic reads from each of the nearly 10,000 'virtual compartments'. We demonstrate the feasibility of this method by assembling >95% of the heterozygous variants in a human genome into long, accurate haplotype blocks (N50 = 1.4-2.3 Mb). The rapid, scalable and cost-effective workflow could enable haplotype resolution to become routine in human genome sequencing. PMID:25326703

    Mobilization of two element subfamilies (canonical and O-type) from Drosophila sturtevanti and D. saltans was evaluated for copy number and transposition activity using the transposon display (TD) technique. Pairwise distances between strains regarding the insertion polymorphism profile were estimated. Amplification of the element based on copy number estimates was highly variable among the strains (D. sturtevanti, canonical 20.11, O-type 9.00; D. saltans, canonical 16.4, O-type 12.60 insertions, on average). The larger values obtained by TD compared to our previous data by Southern blotting support the higher sensitivity of TD over Southern analysis for estimating transposable element copy numbers. The higher numbers of the canonical element and the greater divergence in its distribution within the genome of D. sturtevanti (24.8%) compared to the O-type (16.7%), as well as the greater divergence in the distribution of the canonical P element, between the D. sturtevanti (24.8%) and the D. saltans (18.3%) strains, suggest that the canonical element occupies more sites within the D. sturtevanti genome, most probably due to recent transposition activity. These data corroborate the hypothesis that the O-type is the oldest subfamily of elements in the saltans group and suggest that the canonical element is or has been transpositionally active until more recently in D. sturtevanti.

    ABSTRACT Carbapenemase-producing Enterobacteriaceae (CPE), which are resistant to most or all known antibiotics, constitute a global threat to public health. Transposable elements are often associated with antibiotic resistance determinants, suggesting a role in the emergence of resistance. One insertion sequence, IS26, is frequently associated with resistance determinants, but its role remains unclear. We have analyzed the genomic contexts of 70 IS26 copies in several clinical and surveillance CPE isolates from the National Institutes of Health Clinical Center. We used target site duplications and their patterns as guides and found that a large fraction of plasmid reorganizations result from IS26 replicative transpositions, including replicon fusions, DNA inversions, and deletions. Replicative transposition could also be inferred for transposon Tn4401, which harbors the carbapenemase blaKPC gene. Thus, replicative transposition is important in the ongoing reorganization of plasmids carrying multidrug-resistant determinants, an observation that carries substantial clinical and epidemiological implications for understanding how such extreme drug resistance phenotypes evolve.

    This paper presents a new scheme to improve the performance of finger-vein identification systems. Firstly, a vein pattern extraction method to extract the finger-vein shape and orientation features is proposed. Secondly, to accommodate the potential local and global variations at the same time, a region-based matching scheme is investigated by employing the Scale Invariant Feature Transform (SIFT) matching method. Finally, the finger-vein shape, orientation and SIFT features are combined to ...

    Background: Nutcracker syndrome, also called left renal vein entrapment syndrome, is a cause of non-glomerular hematuria with difficulties in diagnosis. Multidetector computed tomography (MDCT) is a powerful tool to prevent unnecessary diagnostic procedures. Purpose: To retrospectively determine the prevalence of nutcracker phenomenon and nutcracker syndrome seen in MDCT in consecutive patients. Material and Methods: The institutional review board approved the study and waived the requirement for informed consent. Abdominal contrast-enhanced MDCT scans were reviewed from 1000 consecutive patients. MDCT scan assessment included renal vein diameter measurements and evaluation for the presence of anterior or posterior left renal vein entrapment. Electronic medical records and urine analysis reports of patients with left renal vein entrapment were reviewed. Student's t test was used to assess differences in renal vein diameter in patients with left renal vein entrapment. Results: Left renal vein entrapment was observed in 10.9% (109), retroaortic left renal vein in 6.5% (65), entrapment of left renal vein between superior mesenteric artery and aorta in 4.1% (41), and circumaortic left renal vein in 0.3% (3) of patients. Mean diameters of right (8.8 {+-} 1.9 mm) and unentrapped left (8.9 {+-} 1.8 mm) renal veins were not significantly different (P = 0.1). The mean diameter of anterior entrapped left renal veins (10.3 {+-} 2 mm) was significantly greater (P = 0.04) than contralateral renal veins (8.6 {+-} 2.1 mm) in their widest portion. In 8.8% of patients with the left renal vein entrapment, urine analysis showed isomorphic hematuria or proteinuria with no other known cause. Varicocele and pelvic congestion were seen in 5.5% of patients with the left renal vein entrapment. Conclusion: Left renal vein entrapment is not a rare entity and renal nutcracker phenomenon might be underdiagnosed.

    Full Text Available Abstract Background As a main cause of mortality in developed countries, Coronary Artery Disease (CAD is known as silent killer with a considerable cost to be dedicated for its treatment. Coronary Artery Bypass Graft (CABG is a common remedy for CAD for which different blood vessels are used as a detour. There is a lack of knowledge about mechanical properties of human blood vessels used for CABG, and while these properties have a great impact on long-term patency of a CABG. Thus, studying these properties, especially those of human umbilical veins which have not been considered yet, looks utterly necessary. Methods Umbilical vein, as well as human Saphenous vein, are respectively obtained after cesarean and CABG. First, histological tests were performed to investigate different fiber contents of the samples. Having prepared samples carefully, force-displacement results of samples were rendered to real stress–strain measurements and then a fourth-order polynomial was used to prove the non-linear behavior of these two vessels. Results Results were analyzed in two directions, i.e. circumferentially and longitudinally, which then were compared with each other. The comparison between stiffness and elasticity of these veins showed that Saphenous vein’s stiffness is much higher than that of umbilical vein and also, it is less stretchable. Furthermore, for both vessels, longitudinal stiffness was higher than that of circumferential and in stark contrast, stretch ratio in circumferential direction came much higher than longitudinal orientation. Conclusion Blood pressure is very high in the region of aorta, so there should be a stiff blood vessel in this area and previous investigations showed that stiffer vessels would have a better influence on the flow of bypass. To this end, the current study has made an attempt to compare these two blood vessels’ stiffness, finding that Saphenous vein is stiffer than umbilical vein which is somehow as stiff as rat aortic vessels. As blood vessel’s stiffness is directly related to elastin and mainly collagen content, results showed the lower amount of these two contents in umbilical vein regarding Saphenous vein.

    Full Text Available A veia gástrica posterior não é muito citada nos livros de anatomia e nos trabalhos sobre hipertensão porta. Estudou-se sua anatomia, freqüência e desembocadura. Ela foi encontrada em 54% dos casos e, em 100%, desembocava na veia esplênica. Discute-se a vantagem ou não de sua ligadura ou preservação no tratamento cirúrgico da hipertensão porta.The posterior gastric vein has not been mentioned very often neither in anatomy textbooks nor in portal hypertension papers. The authors studied the anatomy, frequency and confluence of this vein because is a huge variety in the presentation of esophageal varices. Twenty-six adult preserved corpses (twenty females and six males had a wide abdominal incision allowing the dissection of the portal system, identifying the frequency and confluence of its tributaries, notably the posterior gastric vein. The portal vein, in all cases, was formed by the confluence of the superior mesenteric vein with the splenic vein and had a mean length of 6.4 cm. The splenic vein had a mean length of 6.5 cm. The left gastric vein was tributary of the portal vein in 50% of the cases and in 30% of the cases in the splenic vein. The right gastric vein had it's confluence to portal vein in 30 % of the cases and to the splenic vein in 4 %. The inferior mesenteric vein was tributary of the splenic vein in 54% of the cases and in the superior mesenteric vein in 46%. The left gastro-omental vein had its confluence to the splenic vein in 50% of the cases and to the inferior polar vein in 34 %. The middle colic vein had its confluence to superior mesenteric vein in 42% of the cases, to inferior mesenteric vein in 12% and to splenic vein in 8%. The posterior gastric vein was found in 54% of the corpses, and in all cases it was a tributary of the splenic vein, in retropancreatic position, coming from the esophageal-gastric junction. These findings agree with previous papers describing a prevalence of 60% of posterior gastric vein in patients submitted to surgery in portal hypertension, and in all cases, this vein was tributary of the splenic vein. The identification of this vein may influence the treatment, because if left untied during cases of portal-azigos disconnection, they may predispose to postoperative bleeding, but in cases of splenorenal anastomosis may preserve its patency in cases of anastomosis occlusion, or can lead again to postoperative bleeding feeding the esophageal varices. To ligate or not this vein will depends on the surgeon 's experience and common sense. Regarding to previous papers and to this data presented here, the authors believe that the prevalence of this vein is between 50 and 60% in the population.

    Full Text Available Background and the purpose of study: Skin aging is a complex process induced by constant exposure to ultraviolet (UV irradiation and damages human skin. UV generates reactive oxygen species leading to collagen deficiency and eventually skin wrinkling. Basil contains a number of phenolics and favonoids which possess antioxidant properties. The aim of this study was to formulate and investigate the antiaging potential of a cream containing Basil extract. Methods: A single blinded study was conducted using non-invasive methods. Formulation containing 3% of the concentrated extract of Basil was developed by entrapping in the inner aqueous phase of w/o emulsion and base contained no extract. Both creams were stored at different storage conditions of 8°C, 25°C, 40°C and 40°C+ 75% relative humidity to predict their stabilities. The formulation and base were evaluated for their effects on various skin parameters i.e., moisture and trans epidermal water loss (TEWL, volume, energy and surface evaluation of the living skin (SELS. Results: Significant effects (p?0.05 were observed for both creams in the case of TEWL. The base showed insignificant (p?0.05 while formulation showed significant effects on skin moisture. Volume, SELS SEr (skin roughness, SEsc (skin scaliness, SEsm (skin smoothness, SEw (skin wrinkles parameter showed significant decline while texture parameter of ‘Energy' showed significant increase. Conclusion: The results statistically indicated that the active formulation containg extract of Basil exert antiaging effects when applied topically.

    Full Text Available INTRODUCTION According to the definition of the World Health Organization, varicose veins represent abnormally enlarged superficial veins having baggy or cylindrical shape. The most frequent cause of primary varicose veins is the insufficiency of long saphenous vein (LSV, but especially the basin of its connection with femoral vein and perforating veins. OBJECTIVE The objectives of these investigations were: the determination of insufficiency incidence of SSV in cases of LSV insufficiency; the establishment of association of insufficiency of perforating veins of the basin of LSV and SSV; the study of the results of surgical treatment of insufficiency and varicosity of both short and long saphenous veins. METHODS In this study, 100 patients (66 women and 34 men, average age 52.1 years, with clinical symptoms showing the insufficiency and varicosity of long saphenous vein with no change of deep vein system were examined. Ultrasonographic examinations were made using Color Doppler probes - 7.5 and 3.75 MHz (Toshiba Corevison SSA 350 A; the development of incompetence of long saphenous vein (LSV and short saphenous vein (SSV at the level of the junction as well as other incompetent valves were examined. The reflux was defined as a retrograde flow of the duration longer than 0.5 seconds. RESULTS The insufficiency of short saphenous vein was determined by ultrasonographic examination in 34%, while the insufficiency of perforating veins in 80% of patients. 40% of patients were operated (33.3% of females, and 52.9% of males. The most frequent indications for surgical treatment of superficial veins insufficiency were: strong varicosities, clear symptoms and signs, superficial thrombophlebitis and conditions after superficial thrombophlebitis. Surgical treatment was applied in 16% of patients due to recurrence in the basin of long saphenous vein, and in 6% of cases because of the recurrence in the basin of short saphenous vein. Data analysis failed to discover any statistically significant difference between the age of patients and varicosities in the basin of long saphenous vein as well as in the basin of short saphenous vein (51.98±9.97 years; 54.50±31.82 years; t=0.36; p>0.05, or any significant difference of BMI value, with regard to the obesity of patients and varicosities in the basin of long saphenous vein as well as in the basin of short saphenous vein (28.02±4.61 kg/m2; 24.50±6.36 kg/m2; t=0.50; p>0.05. No statistically significant correlation was found between Color Duplex findings of insufficiency of both long saphenous vein and short saphenous vein (p=-0.21 ; p>0.05, nor any significant correlation of Color Duplex findings of perforating veins insufficiency in the basin of long saphenous vein and short saphenous vein (p=-0.115; p>0.05. CONCLUSION The incidence of insufficiency is significant: approximately every third patient has short saphenous vein insufficiency, while three third of patients have perforating veins insufficiency. Color Duplex limb's veins ultrasonography is highly reliable method for the examination and study of superficial veins diseases, which is very important for preoperative decision-making and selection of surgical technique as well as for postoperative follow-up.

  5. Radionuclide angiographic evaluation of right and left ventricular function during exercise after repair of transposition of the great arteries. Comparison with normal subjects and patients with congenitally corrected transposition

    International Nuclear Information System (INIS)

    We assessed the incidence, clinical significance and etiology of ventricular dysfunction after intraatrial repair of d-transposition of the great arteries in 11 patients, mean age 9 +/- 3 years, who had had Mustard operations. We compared the results to 15 patients who were considered to have normal ventricular function, two patients who had Rastelli operations and five patients with congenitally corrected transposition. Gated equilibrium radionuclide angiography with supine exercise stress testing was used to assess these children. We found no significant difference between our patient groups in exercise capacity, heart rate, or blood pressure response to exercise. However, we found a high incidence of right ventricular dysfunction in the patient groups, manifested by an abnormal right ventricular ejection fraction response to dysfunction in the patient groups, manifested by an abnormal right ventricular ejection fraction response to exercise in six of 11 patients with a Mustard repair, both patients with a Rastelli repair and all five with congenitally corrected transposition. In addition, the left ventricular response to exercise was abnormal in 10 of 11 patients who had undergone a Mustard repair, both patients with a Rastelli repair, and two of five patients with congenitally corrected transposition. We conclude that biventricular dysfunction is frequently present after intraatrial repair of d-transposition of the great arteries. Despite this dysfunction, no significant decrease in exercise tolerance is found in childhood

    Conclusion: The lessons we learned are (1 Before SMPV confluence resection, internal jugular vein graft should be ready for reconstruction. (2 Synthetic graft is an alternative for internal jugular vein graft. (3 Direct portal vein to SMV anastomosis can be achieved by mobilizing liver. (4 It is possible that venous collaterals secondary to SMV tumor obstruction may have allowed this patient's post-operative survival.

    The veins of the dentate nucleus are composed of several channels draining the external surface and one single vein draining the internal surface. We analyzed specimens of the human cerebellum and described the central vein of the nucleus dentatus as the main venous outflow of the nucleus. The central vein of the nucleus dentatus is formed by a network of smaller vessels draining the sinuosities of the gray matter; it emerges from the hilum of the nucleus and runs along the superior cerebellar peduncle, opening in the anterior vermian vein. We looked for this structure and for the surrounding veins on ultra-high-field (7 Tesla) MR, using susceptibility-weighted imaging. An anatomical and radiological description of the veins of the dentate nucleus is provided, with some remarks on the future clinical applications that these findings could provide. PMID:20659570

  10. Lower extremity dep vein thrombosis in children

    International Nuclear Information System (INIS)

    Of 113 leg venograms performed in patients of all ages between 1969 and 1982, 68 were in children 16 years old or less. The patients were all studied on a tilt table (method of Rabinov and Paulin) in a head-up, 40-500 incline without tourniquets, supporting their weight on the unaffected leg. Among the 68 venograms, 12 (18%) were positive for deep vein thrombosis. The clinical settings for thrombosis in children were post-catheterization (two patients), post surgery (two), tumor/tumor therapy (three), drug abuse (one), and idiopathic (three). There were no long-term clinical sequelae in five patients. Pulmonary infarction occurred in three, and three patients required either long-term anticoagulation or IVC clipping. Clinical diagnosis is no more accurate for the diagnosis of deep vein thrombosis in children than it is in adults. Venography is the best method for making an accurate diagnosis and directing subsequent therapy.(orig.)

    Kabuki syndrome (KS) comprises multiple congenital abnormalities and is characterized by a peculiar facial appearance, dermatoglyphic anomalies, mental retardation, skeletal abnormalities and postnatal growth retardation. We describe the case of a 23-month-old boy with the typical features of KS who had several malformations in the veins of the brain, which had not previously been described in patients with this syndrome. The MRI phlebogram of this patient showed that the vein of Galen was dilated and that it drained anomalously. The sinus rectus was abnormal and the longitudinal inferior venous sinus was absent. In view of this finding, together with the fact that structural brain abnormalities in KS are more frequent than in other congenital syndromes with multiple malformations, we propose that MRI be used in the diagnostic work-up of all patients with KS.

    Anticoagulant therapy is associated with poor late limb outcomes in many patients with deep vein thrombosis (DVT). Because systemic thrombolysis and surgical thrombectomy have inherent limitations, image-guided percutaneous thrombus removal is currently favored. Pharmacologic thrombolysis is effective in removing thrombus, but long-term benefit has not been conclusively demonstrated and major bleeding rates appear to be higher than those observed with anticoagulation alone.

    Portal vein thrombosis (PVT) is considered to be a frequent complication of liver cirrhosis. However, unlike PVT in patients without cirrhosis, very few data are available on the natural history and management of PVT in cirrhosis, despite its association with potentially life-threatening conditions, such as gastroesophageal bleeding and acute intestinal ischemia. Moreover, no consensus regarding PVT in cirrhosis exists. Suggested causes of PVT in cirrhosis include reduced portal blood flow ve...

    Full Text Available We report a case of a patient with deep vein thrombosis (DVT and pulmonary thromboembolism (PTE associated to portal vein thrombosis (PVT, complicated by hospital-acquired pneumonia (HAP. The pathogenesis of DVT is multifactorial; among risk factors we can list: transitory situations (surgical interventions, infectious diseases with fever, traumas, acquired conditions (neoplasms, antiphospholipid syndrome or genetically determined situations (thrombophilia. PVT of the sovrahepatic veins is responsible for 5-10% of portal hypertension cases in adults and can be associated to local or systemic infections. PVT is present in 10% of patients with cirrhosis and often associated to cancers. It can also complicate a surgery abdominal intervention. HAP is defined as pneumonia that appears for the first time within 48 h of hospital admission. In Internal Medicine Departments the incidence is 7-10 cases/1.000 of hospital admissions, with an important impact in terms of both mortality and morbility. An early diagnosis, together with a correct identification of microbiologic agents in cause, allows a suitable antibiotic therapy with consequent improvement of clinical prognosis and a meaningful reduction of mortality. Main risk factors are: age, hospital and department. An important variable to be considered is the onset of pneumonia. The later is the onset of HAP (5 or more days from the admission to hospital, the more often is associated to multidrug resistant (MRD microorganisms, poorly responsive to antibiotic.

    Full Text Available Salmonella enterica serotype Enteritidis is known as one of the most common pathogenic bacteria causing salmonellosis in humans. Raw materials of animal origin (eggs, chicken meat are frequent vectors that transmit this bacterium. Since eggs are used for the production of pasta, due to insufficient thermal treatment during pasta drying, they can be a potential risk to consumer health. Different essential oils of herbs can be used to reduce present pathogenic microorganisms. This paper compares a decrease in the number of Salmonella enterica serotype Enteritidis (D ATCC 13076 and Salmonella enterica serotype Enteritidis isolated from outbreaks of salmonellosis in egg-based pasta under the influence of thyme and sweet basil essential oils. The results indicate that the utilized oils were more effective against the epidemic strain than the ATCC strain. In addition, thyme oil caused a more significant inhibition of Salmonella enterica serotype Enteritidis during the production process.

    Full Text Available The essay ascertains that the monastic center located on Mount Athos and the Ohrid Archbishopric played a very important role in the policies pursued by Basil II. It was during his rule that the first foreign monasteries, which later Greek sources refer to as monastic communities ??????? ??????? (Iveron and Amalfi, were established. The third monastery displaying this characteristic was the Serbian monastery Hilandar. Since Hilandar had been established after the Bulgarian and Russian monasteries, the question arose why sources dating from the late 12th century do not mention Zographou and St. Panteleimon’s monastery among the ??????? ??????? monasteries. The answeris to be found in the circumstances surrounding the establishment of Slavic monasteries on Mount Athos. The essay also assesses the importance of Mount Athos and the Ohrid Archbishopric for the process of deeper integration of Slavs into the Byzantine religious and political-ideological system.

    This study describes the effect of water stress and storage time on the content of anthocyanins and other phenolics in different genotypes of fresh sweet basil (Ocimum basilicum L.). Purple and green Iranian cultivars and a Genovese variety were exposed to a control (100% of the field capacity, FC) and to water stress of mild and severe deficit irrigation treatments (25 and 50 DI corresponding to 75 and 50% FC, respectively). The individual characterization by HPLC-DAD-ESI/MS(n) and the MS fragmentation pathway of anthocyanins are described. A 50% increase in the anthocyanin content was observed in 50 DI after storage. Water stress markedly enhanced the content of phenolic acids after storage in the three genotypes. Water stress can be an efficient way to help the sustainability of water resources, enriching the content of phenolic compounds that may be beneficial to human health. PMID:26473474

    Mineral precipitation significantly effects many aspects of fluid-rock interaction across all length scales, as the dynamical change of permeability, of mechanical interaction and redistribution of dissolved material. The hydrothermal growth of quartz establishes one of the most important mineralization processes in fractures. Tectonically caused fracturing, deformation and fluid transport leaves clear detectable traces in the microstructure of the mineralized veins. As these patterns give hints on the deformation history and the fluid pathways through former fracture networks, accurate spatio-temporal modeling of vein mineralization is of special interest, and the objective of this study. Due to the intricate polycrystalline geometries involved, the underlying physical processes like diffusion, advection and crystal growth have to be captured at the grain scale. To this end, we adapt a thermodynamically consistent phase-field model (PFM), which combines a kinetic growth law and mass transport equations with irreversible thermodynamics of interfaces and bulk phases. Each grain in the simulation domain is captured by a phase field with individual orientation given by three Euler angles. The model evolves in discrete time steps using a finite difference algorithm on a regular grid, optimized for large grain assemblies. The underlying processes are highly nonlinear, and for geological samples, boundary conditions as well as many of the physical parameters are not precisely known. One motivation in this study is to validate the adequately parameterized model vs. hydrothermal experiments under defined (p,T,c) conditions. Different from former approaches in vein growth simulation, the PFM is configured using thermodynamic data from established geochemical models. Previously conducted batch flow experiments of hydrothermal quartz growth were analyzed with electron backscatter diffraction (EBSD) and used to calibrate the unknown kinetic anisotropy parameters. In the simulations, we study the sealing of syntaxial veins of 300 microns aperture by epitaxial overgrowth of preexisting grains from the rock surface. Results from 3D simulations conducted in the limit of low Damköhler numbers explain the observed transition regime in competitive crystal growth for blocky-elongate veins. The initial formation of quartz crystal bridges, especially pronounced in the regime of low supersaturation, is observed. The morphological evolution of micro-ensembles of grain neighbourhoods from the rock sample compares well to that of the simulations. To juxtapose larger polycrystal domains, the variation of grain number, texture and porosity as function of scaled distance from the initial wall is calculated. Velocity profiles from solutions of the isothermal incompressible Navier-Stokes equation are used to record permeability evolution and to evaluate deviations from the cubic law. Both, the geometry of the microstructure and the permeability of the flow pathway, are used as upscaling parameters for larger scale (fracture scale) simulations.

    Full Text Available Mass production of medicinal and aromatic plants under hydroponic systems and especially in areas with saline soils is very important. An experiment was conducted to evaluate the interaction of salinity stress and foliar application of zinc (Zn on hydroponically-grown basil (Ocimum basilicum L.. The factorial experiment was arranged as randomized complete blocks design, with two salinity levels (0 and 50 mM NaCl and three Zn levels (0, 100 and 200 mg/L as ZnSO4,7H2O and three replications. Some growth characteristics such as height, leaf surface area, fresh and dry weight of leaves, stem and whole plant, chlorophyll index, harvest index and yield of dry leaves per m2 were measured. After extraction of essential oil, the oil yield was calculated based on oil content in the plant. The results showed that salinity stress adversely affected all growth characteristics as well as essential oil content and yield. Despite the generally accepted hypothesis, Zn application not only had no impact on reducing the negative effects of salinity, but also showed no significant difference between the control plants (no salinity. The highest essential oil content and yield were recorded for control plants. Therefore, it is concluded that under the hydroponics system, basil is sensitive to 50 mM salinity, and Zn foliar application up to 200 mg/L had no positive impact on the reduction of negative effects of salinity. Thus, control nutrient solution has appropriate amount of Zn for salinity stress conditions.

  9. The Effect of Static Magnetic Forces on Water Contents and Photosynthetic Pigments in Sweet Basil Ocimum basilicum L. (Lamiaceae)

    International Nuclear Information System (INIS)

    Three different magnetic regimes; aerial, surface and buried; each with three different forces, have been used to investigate their effects on the water contents and photosynthetic pigments of sweet basil plants (Ocimum basilicum L.). Two groups of sweet basil seeds, Ocimum basilicum L. have been cultivated, one under normal conditions and the second has been subdivided into three portion (aerial, surface and buried) to examine the effect of different magnetic forces coming from the three directions on the resulted plants. At all directions of magnets, water contents have been significantly affected by the magnetic forces. Chlorophyll A and carotene contents have been affected, as well, according to the three magnetic forces coming from soil surface regime only. Chlorophyll B did not significantly affected by differences magnetic forces in the three regimes, but it is affected by magnetism wherever its direction or force. But all the photosynthetic pigments contents (Chlorophyll A, B and Carotenes) decreased significantly than the control in the three magnetic regimes., but without any effect according to differences in the magnetic force in the aerial and burried regimes of magnetism. It was concluded that magnetism affects both water absorption and retention , the most influenced regime was the aerial magnets followed by the surface and buried ones. This result can be interpreted by the ionization of water which makes water ions respond to magnetic forces. Photosynthetic pigments have been decreased significantly by the exposure to magnetic fields, irrespective to its direction or force and this may be due to the effect of magnetic fields on the reduction in plastids inside the cells.

    Goldfish Tgf2 transposon of Hobo/Activator/Tam3 (hAT) family can mediate gene insertion in a variety of aquacultural fish species by transposition; however, the protein structure of Tgf2 transposase (TPase) is still poorly understood. To express the goldfish Tgf2 TPase in Escherichia coli, the 2061-bp coding region was cloned into pET-28a(+) expression vector containing an N-terminal (His)6-tag. The pET-28a(+)-Tgf2 TPase expression cassette was transformed into Rosetta 1 (DE3) E. coli lines. A high yield of soluble proteins with molecular weight of ~80 kDa was obtained by optimized cultures including low-temperature (22 °C) incubation and early log phase (OD600 = 0.3-0.4) induction. Mass spectrometry analysis following trypsin digestion of the recombinant proteins confirmed a Tgf2 TPase component in the eluate of Ni(2+)-affinity chromatography. When co-injected into 1-2 cell embryos with a donor plasmid harboring a Tgf2 cis-element, the prokaryotic expressed Tgf2 TPase can mediate high rates (45 %) of transposition in blunt snout bream (Megalobrama amblycephala). Transposition was proved by the presence of 8-bp random direct repeats at the target sites, which is the signature of hAT family transposons. Production of the Tgf2 Tpase protein in a soluble and active form not only allows further investigation of its structure, but provides an alternative tool for fish transgenesis and insertional mutagenesis.

    García-Lobo Juan M

    2008-01-01

    Full Text Available Abstract Background The Brucella genome contains an insertion sequence (IS element called IS711 or IS6501, which is specific to the genus. The copy number of IS711 varies in the genome of the different Brucella species, ranging from 7 in B. abortus, B. melitensis and B. suis to more than 30 in B. ovis and in Brucella strains isolated from marine mammals. At present, there is no experimental evidence of transposition of IS711, but the occurrence of this element with a high copy number in some species, and the isolation of Brucella strains with "ectopic" copies of IS711 suggested that this IS could still transpose. Results In this study we obtained evidence of transposition of IS711 from the B. ovis and B. pinnipedialis chromosomes by using the "transposon trap" plasmid pGBG1. This plasmid expresses resistance to tetracycline only if the repressor gene that it contains is inactivated. The strains B. melitensis 16 M, B. abortus RB51, B. ovis BOC22 (field strain and B. pinnipedialis B2/94, all containing the plasmid pGBG1, were grown in culture media with tetracycline until the appearance of tetracycline resistant mutants (TcR. TcR mutants due to IS711 transposition were only detected in B. ovis and B. pinnipedialis strains. Conclusion Four different copies of IS711 were found to transpose to the same target sequence in the plasmid pGBG1. This demonstrated that IS711 are active in vivo, specially in Brucella species with a high number of IS711 copies as B. ovis and B. pinnipedialis.

    Full Text Available BACKGROUND: The procedure of choice in the surgical treatment of cubital tunnel syndrome remains controversial. The aim of this study is to report the results of simple decompression and decompression with anterior subcutaneous transposition. METHODS: A retrospective review (July 2002-January 2007) [...] using the Bishop Score to assess outcome. A total of 102 procedures (91 patients, 11 bilateral) were performed with a minimum of 9 months' post-operative follow-up. The procedure was selected intra-operatively. All cases were operated by the senior author (MC). RESULTS: In the simple decompression group (n=47, average age 45.9 years), the average Bishop Score was 11.3 (5-13) with an average time to recovery of 3.7 months (1-6). Good to excellent results were obtained in 94% and fair results in 6%. In the anterior transposition group (n=55, average age 43.3 years) the average Bishop Score was 10.6 (5-13) with average time to recovery of 4.2 months (1-6). Good to excellent results were obtained in 93% and fair results in 7%. Complications included subluxation of the ulnar nerve in two cases, one wound dehiscence and one post-operative haematoma. CONCLUSIONS: The outcome in both groups was the same. Recovery is often prolonged. It took 3-6 months for 69% of patients to recover. Younger patients recovered sooner and the transposition and elderly groups took longer to recover. Simple decompression is adequate unless the nerve is unstable or the bed unsuitable.

    Cerebral small vessel disease is common in elderly persons and a leading cause of cognitive decline, dementia, and acute stroke. With the introduction of ultra-high field strength 7.0T MRI, it is possible to visualize small vessels in the brain. In this work, a proof-of-principle study is conducted to assess the feasibility of automatically detecting periventricular veins. Periventricular veins are organized in a fan-pattern and drain venous blood from the brain towards the caudate vein of Schlesinger, which is situated along the lateral ventricles. Just outside this vein, a region-of- interest (ROI) through which all periventricular veins must cross is defined. Within this ROI, a combination of the vesselness filter, tubular tracking, and hysteresis thresholding is applied to locate periventricular veins. All detected locations were evaluated by an expert human observer. The results showed a positive predictive value of 88% and a sensitivity of 95% for detecting periventricular veins. The proposed method shows good results in detecting periventricular veins in the brain on 7.0T MR images. Compared to previous works, that only use a 1D or 2D ROI and limited image processing, our work presents a more comprehensive definition of the ROI, advanced image processing techniques to detect periventricular veins, and a quantitative analysis of the performance. The results of this proof-of-principle study are promising and will be used to assess periventricular veins on 7.0T brain MRI.

  15. Development of HIFU Therapy System for Lower Extremity Varicose Veins

    International Nuclear Information System (INIS)

    High-intensity focused ultrasound (HIFU) treatment utilizing microbubbles was investigated in the present study. It is known that microbubbles have the potential to enhance the heating effects of an ultrasound field. In this study, the heat accompanying microbubble oscillation was used to occlude varicose veins. Alteration of veins was observed after ultrasound irradiation. Veins were resected by stripping. In this study, two vein conditions were adopted during HIFU irradiation; non-compressed and compressed. Compressing the vein was expected to improve occlusion by rubbing the altered intima under compressed conditions. The frequency of the ultrasound was 1.7 MHz, the intensity at the focus was 2800 W/cm2, and the irradiation time was 20 s. In this study, the contrast agent Levovist registered was chosen as a microbubble source, and the void fraction (ratio of total gas volume to liquid) in the vein was fixed at 10-5. Under non-compressed conditions, changes were observed only at the adventitia of the vein anterior wall. In contrast, under compressed conditions, changes were observed from the intima to the adventitia of both the anterior and posterior walls, and they were partly stuck together. In addition, more experiments with hematoxylin-eosin staining suggested that the changes in the vein were more substantial under the latter conditions. From these results, it was confirmed that the vein was occluded more easily with vein compression.

The results were as follows: 1. In 36 cases, portal vein thrombosis was detected during photography. Nineteen of 37 cases which revealed localized hepatoma in the right lobe of the liver showed portal vein thrombosis; 9 of 11 cases of the left lobe; 8 of 14 cases which were involved in entire liver revealed thrombosis. One case localized in the caudate lobe showed no evidence of invasion to portal vein. 2. Twenty-four of 34 cases with diffuse infiltrative hepatoma revealed portal vein thrombosis and the incidence of portal vein thrombosis in this type were higher than in the cases of the nodular type. 3. The portal vein thrombosis appeared as filling defects of low density in the lumen of the portal veins in CT and they did not reveal contrast enhancement. 4. CT revealed well the evidence of obstructions in the cases of portal vein thrombosis and the findings were well-corresponded to the findings of the superior mesenteric photography. 5. Five of the cases of the portal vein thrombosis were missed in the CT and the causes were considered as due to partial volume effect of enhanced portal vein with partial occlusion or arterioportal shunts. 6. Six of 13 cases with occlusion of main portal vein showed cavernous transformation and they were noted as multiple small enhanced vascularities around the porta hepatis in the CT. According to the results, we conclude that CT is a useful modality to detect the changes of the portal veins in the patients of the hepatoma.

    A plasmid containing the transposon gamma delta sequence was immune to further insertion of gamma delta (transposition immunity). Plasmids carrying a fragment containing either 0.2 kilobase pairs of the gamma end or 0.4 kilobase pairs of the delta end of the gamma delta sequence were immune, and other parts of the gamma delta sequence did not confer immunity. The terminal 38-base-pair (bp) sequence of the delta end of the gamma delta was sufficient to confer immunity, the 38-bp sequence of th...

  19. Isolated laevocardia and corrected transposition of the great vessels with total situs inversus

    International Nuclear Information System (INIS)

    Isolated laevocardia combined with corrected transposition of the great arteries and complete situs inversus is rare. Due to discordant interrelationships between atria and ventricles and between ventricles and great arteries, both anomalies result in a normal circulation. In the presented case no associated cardiac malformations were present and the 55-year-old woman remained symptom-free for a long time until she developed an acquired valve disease. A systematic approach to chamber localisation in complex morphologic lesions of the heart is reviewed, and the value of CT, which can be applied successfully in older children and adults is demonstrated.

    Over the last 50 years, improved surgical techniques and progressive medical management have allowed patients with complete or dextro-transposition of the great arteries (D-TGA) to survive into adulthood. Older adult patients underwent an atrial switch procedure (Mustard or Senning operation), whereas the younger cohort of patients with TGA has undergone the arterial switch operation (ASO). The Mustard/Senning maintains the right ventricle as the systemic ventricle, whereas the more recently adopted ASO attempts to restore normal physiologic and anatomic relationships. Neither operation is without consequence. Neither is without consequence and require long term follow up. PMID:26471819

    Full Text Available Congenitally corrected transposition of the great arteries (ccTGA is a complex cardiac anomaly with an unfavorable natural history. Surgical treatment has been available for over 50 years. Initial procedures used for ccTGA did not correct atrio-ventricular discordance, leaving the right ventricle in systemic position. In the past two decades anatomic repair has been considered to be a better option. Many cases subjected to anatomic repairs would also be suitable for the Fontan strategy, which probably has a lower initial risk. The rationale for use of the Fontan operation in management of congenitally corrected transposition is discussed in this review, with comparisons to other strategies.

    The Mineral Vein Dynamics Modeling group ''FRACS'' is a team of 7 research groups from the Universities of Mainz, Aachen, Tuebingen, Karlsruhe, Bayreuth, ETH Zuerich and Glasgow working on an understanding of the dynamic development of fracturing, fluid flow and fracture sealing. World-class field laboratories, especially carbonate sequences from the Oman Mountains are studied and classified. State of the art numerical programs are written, expanded and used to simulate the dynamic interaction of fracturing, flow and resealing and the results are compared with the natural examples. Newest analytical technologies including laser scanning, high resolution X-ray microtomography, fluid inclusion and isotope analysis are performed to understand and compare the results of simulations with natural examples. A new statistical program was developed to classify the natural fracture and vein systems and compare them with dynamic numerical simulations and analytical models. The results of the first project phase are extremely promising. Most of the numerical models have been developed up to the stage where they can be used to simulate the natural examples. The models allow a definition of the first proxies for high fluid pressure and tectonic stresses. It was found out that the Oman Mountains are a complex and very dynamic system that constantly fractures and reseals from the scale of small veins up to the scale of large normal and strike slip faults. The numerical simulations also indicate that the permeability of such systems is not a constant but that the system adjusts to the driving force, for ex-ample high fluid pressure. When the system reseals fast a fluctuating behavior can be observed in the models where the system constantly fractures and reseals, which is in accordance with the observation of the natural laboratory.

    Unilateral pulmonary vein atresia is a rare congenital anomaly. Its symptoms begin to manifest in childhood and a broad spectrum of clinical severity has been described, ranging from asymptomatic, recurrent pulmonary infection, severe hemoptysis, to death. Only a few adult cases with this condition, with no or mild symptoms, have been reported. Pulmonary angiography has been typically used for definite diagnosis. However, pulmonary angiography may be replaced with the current developing multidetector CT. This report presents an adult case with mild symptoms, diagnosed by multidetector CT.

    The differentiation of veins in the Drosophila wing relies on localised expression of decapentaplegic (dpp) in pro-vein territories during pupal development. The expression of dpp in the pupal veins requires the integrity of the shortvein region (shv), localised 5? to the coding region. It is likely that this DNA integrates positive and negative regulatory signals directing dpp transcription during pupal development. Here, we identify a minimal 0.9 kb fragment giving localised expression in t...

    This paper presents a new scheme to improve the performance of finger-vein identification systems. Firstly, a vein pattern extraction method to extract the finger-vein shape and orientation features is proposed. Secondly, to accommodate the potential local and global variations at the same time, a region-based matching scheme is investigated by employing the Scale Invariant Feature Transform (SIFT) matching method. Finally, the finger-vein shape, orientation and SIFT features are combined to further enhance the performance. The experimental results on databases of 426 and 170 fingers demonstrate the consistent superiority of the proposed approach. PMID:24196433

    We present a three-dimensional computer simulation of the dynamics of a vein valve. In particular, we couple the solid mechanics of the vein wall and valve leaflets with the fluid dynamics of the blood flow in the valve. Our model captures the unidirectional nature of blood flow in vein valves; blood is allowed to flow proximally back to the heart, while retrograde blood flow is prohibited through the occlusion of the vein by the valve cusps. Furthermore, we investigate the dynamics of the va...

    International Nuclear Information System (INIS)

    The importance of phlebography and vaso-occlusion using ethibloc in diagnosis and treatment of the persistent varicocele following ligation ('Bernardis' technique') is demonstrated. We performed 280 surgical ligations of the internal spermatic vein. In 30 patients persistence of the varicocele was found. In 9 patients following phlebography embolisation of a long segment including smaller collaterals was performed using ethibloc. The other 21 patients were treated surgically because of unusual draining of the collaterals into renal capsular veins, into the hemiazygos vein and into renal segmental veins. In all cases following embolisation complete resolution of the varicocele was observed within 3 months. (orig.)

The purpose of the present study was to examine the effect of feeding with forage materials including maize silage, herbs or kale on egg production and various egg quality parameters of the shell, yolk colour, egg albumen, sensory properties, fatty acid and carotenoid composition of the egg yolk. 2. A total of 5 dietary treatments were tested for 5 weeks, consisting of a basal organic feed plus 120 g/ hen.d of the following forage materials: 1) maize silage (control), 2) maize silage incl. 15 g/kg basil, 3) maize silage incl. 30 g/kg basil, 4) maize silage incl. 15 g/kg thyme, or 5) fresh kale leaves. Each was supplied to three replicates of 20 hens. A total of 300 hens was used. 3. Feed intake, forage intake and laying rate did not differ with treatment, but egg weight and egg mass produced increased significantly with the kale treatment. 4. The egg shell strength tended to be higher with the kale treatment, andegg yolk colour was significantly more red with the kale treatment and more yellow with basil and kale treatments. The albumen DM content and albumen gel strength were lowest with the thyme treatment. By sensory evaluation, the kale treatment resulted in eggs with less sulphur aroma, higher yolk colour score, and more sweet and less watery albumen taste. Furthermore, the eggs of the kale treatment had significantly higher lutein and -carotene content. Also, violaxanthin, an orange xanthophyll, tended to be higher in kale and eggs from hens receiving kale. 5. In conclusion, forage material, especially basil and kale, resulted in increased egg production and eggs of high and differentiable quality.

The‘Fino Verde’cultivar fertilized with urea accumulated the least quantities of nitrates in the basil herb.

  3. A 5-methylcytosine DNA glycosylase/lyase demethylates the retrotransposon Tos17 and promotes its transposition in rice

    2011-09-06

    DNA 5-methylcytosine (5-meC) is an important epigenetic mark for transcriptional gene silencing in many eukaryotes. In Arabidopsis, 5-meC DNA glycosylase/lyases actively remove 5-meC to counter-act transcriptional gene silencing in a locus-specific manner, and have been suggested to maintain the expression of transposons. However, it is unclear whether plant DNA demethylases can promote the transposition of transposons. Here we report the functional characterization of the DNA glycosylase/lyase DNG701 in rice. DNG701 encodes a large (1,812 amino acid residues) DNA glycosylase domain protein. Recombinant DNG701 protein showed 5-meC DNA glycosylase and lyase activities in vitro. Knockout or knockdown of DNG701 in rice plants led to DNA hypermethylation and reduced expression of the retrotransposon Tos17. Tos17 showed less transposition in calli derived from dng701 knockout mutant seeds compared with that in wild-type calli. Overexpression of DNG701 in both rice calli and transgenic plants substantially reduced DNA methylation levels of Tos17 and enhanced its expression. The overexpression also led to more frequent transposition of Tos17 in calli. Our results demonstrate that rice DNG701 is a 5-meC DNA glycosylase/lyase responsible for the demethylation of Tos17 and this DNA demethylase plays a critical role in promoting Tos17 transposition in rice calli.

    Full Text Available Objectives: The purpose of this first part of a two-part series was to review the literature concerning the indications, contraindications, advantages, disadvantages and surgical techniques of the lateralization and transposition of the inferior alveolar nerve, followed by the placement of an implant in an edentulous atrophic posterior mandible. Material and Methods: A comprehensive review of the current literature was conducted according to the PRISMA guidelines by accessing the NCBI PubMed and PMC database, academic sites and books. The articles were searched from January 1997 to July 2014 and comprised English-language articles that included adult patients between 18 and 80 years old with minimal residual bone above the mandibular canal who had undergone inferior alveolar nerve (IAN repositioning with a minimum 6 months of follow-up. Results: A total of 16 studies were included in this review. Nine were related to IAN transposition, 4 to IAN lateralization and 3 to both transposition and lateralization. Implant treatment results and complications were presented. Conclusions: Inferior alveolar nerve lateralization and transposition in combination with the installation of dental implants is sometimes the only possible procedure to help patients to obtain a fixed prosthesis, in edentulous atrophic posterior mandibles. With careful pre-operative surgical and prosthetic planning, imaging, and extremely precise surgical technique, this procedure can be successfully used for implant placement in edentulous posterior mandibular segments.

    Full Text Available Abstract Background Complete transposition of the great arteries is a congenital cardiac malformation occasionally encountered in cattle and other species. The objective of the present report was to provide a detailed clinical, echocardiographic and post mortem description of a calf presenting with this condition. Case presentation A 6-week old male Belgian Blue cross-breed calf was examined for respiratory distress and exercise intolerance. The patient was bright, alert and responsive without any neurologic abnormalities but was exercise intolerant, had marked cyanosis, tachycardia, tachypnea, a pansystolic heart murmur as well as a bilaterally palpable thrill over the heart. Arterial blood gas analysis revealed marked hypoxemia (PaO2 = 23 mmHg, O2sat = 41.1%, mild hypercapnia and compensated respiratory acidosis. Echocardiographic examination revealed a complete transposition of the great arteries in combination with a ventricular septal defect through which blood shunted bidirectionally. Cardiac catheterization confirmed that arterialization of blood of the systemic circulation solely occurred in the right ventricle through blood shunting from the left into the right ventricle. Results of post mortem examination are presented. Conclusion Complete transposition of the great arteries is a cyanotic congenital anomaly repeatedly reported in calves that should be considered as differential diagnosis in patients presenting with hypoxemia more severe than commonly encountered with other congenital cyanotic heart conditions. We give a comprehensive summary of the clinical presentation, diagnostic work-up and post mortem examination of a Belgian Blue cross-breed calf with complete transposition of the great arteries

    Background Transposition of the great arteries is one of the most commonly diagnosed conotruncal heart defects at birth, but its etiology is largely unknown. The anterior heart field (AHF) that resides in the anterior pharyngeal arches contributes to conotruncal development, during which heart progenitors that originated from the left and right AHF migrate to form distinct conotruncal regions. The aim of this study is to identify abnormal AHF development that causes the morphology of transposition of the great arteries. Methods and Results We placed a retinoic acid–soaked bead on the left or the right or on both sides of the AHF of stage 12 to 14 chick embryos and examined the conotruncal heart defect at stage 34. Transposition of the great arteries was diagnosed at high incidence in embryos for which a retinoic acid–soaked bead had been placed in the left AHF at stage 12. Fluorescent dye tracing showed that AHF exposed to retinoic acid failed to contribute to conotruncus development. FGF8 and Isl1 expression were downregulated in retinoic acid–exposed AHF, and differentiation and expansion of cardiomyocytes were suppressed in cultured AHF in medium supplemented with retinoic acid. Conclusions The left AHF at the early looped heart stage, corresponding to Carnegie stages 10 to 11 (28 to 29 days after fertilization) in human embryos, is the region of the impediment that causes the morphology of transposition of the great arteries.

    Full Text Available Abstract Background Proliferation and migration of vascular smooth muscle cells (VSMCs play a key role in neointimal formation which leads to restenosis of vein graft in venous bypass. STAT-3 is a transcription factor associated with cell proliferation. We hypothesized that silencing of STAT-3 by siRNA will inhibit proliferation of VSMCs and attenuate intimal thickening. Methods Rat VSMCs were isolated and cultured in vitro by applying tissue piece inoculation methods. VSMCs were transfected with STAT 3 siRNA using lipofectamine 2000. In vitro proliferation of VSMC was quantified by the MTT assay, while in vivo assessment was performed in a venous transplantation model. In vivo delivery of STAT-3 siRNA plasmid or scramble plasmid was performed by admixing with liposomes 2000 and transfected into the vein graft by bioprotein gel applied onto the adventitia. Rat jugular vein-carotid artery bypass was performed. On day 3 and7 after grafting, the vein grafts were extracted, and analyzed morphologically by haematoxylin eosin (H&E, and assessed by immunohistochemistry for expression of Ki-67 and proliferating cell nuclear antigen (PCNA. Western-blot and reverse transcriptase polymerase chain reaction (RT-PCR were used to detect the protein and mRNA expression in vivo and in vitro. Cell apoptosis in vein grafts was detected by TUNEL assay. Results MTT assay shows that the proliferation of VSMCs in the STAT-3 siRNA treated group was inhibited. On day 7 after operation, a reduced number of Ki-67 and PCNA positive cells were observed in the neointima of the vein graft in the STAT-3 siRNA treated group as compared to the scramble control. The PCNA index in the control group (31.3 ± 4.7 was higher than that in the STAT-3 siRNA treated group (23.3 ± 2.8 (P Conclusions The STAT-3 siRNA can inhibit the proliferation of VSMCs in vivo and in vitro and attenuate neointimal formation.

  14. Semi-field cage studies on the evaluation of basil oil as an attractant for male Mediterranean fruit fly, Ceratitis capitata (Wied.)

    International Nuclear Information System (INIS)

    The Sterile Insect Technique (SIT) is an environmentally benign approach for suppressing or eradicating insect pests and is widely used in integrated programmes against tephritid fruit fly pests, particularly the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) Ecological studies of fruit flies have long depended on the methods developed for trapping the fly in the field. The improvement of attractant lures for fruit flies has become a great tool for population suppression before starting a programme integrating the SIT and as a monitor tool during the programme. Moreover, the attractant can be used to induce artificial aggregation of sterile and wild males and mating can be observed at these sites. In 1998, laboratory tests conducted in Egypt, demonstrated that basil oil can be used as attractant for male medfly. The present study deals with the evaluation of basil oil as an attractant for fertile wild type males (EGII Strain), as well as irradiated and non-irradiated mass-reared males from a genetic sexing strain based on a temperature sensitive lethal (tsl) mutation (Vienna-7 mix). The males were tested in field cages located at the FAO/ IAEA Agriculture and Biotechnology Laboratory (Seibersdorf, Austria). Baited Jackson traps were used for attraction of males. The results of the first experiment showed that, for 24 hours, the basil oil attracted 67% of the non- irradiated V-7 mix males, while only 54% of the irradiated (100 Gy) of V-7 mix males were attracted. A different field cage was used for each of the irradiated and non-irradiated males. The second experiment showed that, 65% of the fertile wild medfly males (EGII) were attracted, while only 32% of the irradiated V-7 mix males were attracted. Both types of males were contained in one cage. The data obtained has shown that basil oil can be used as medfly attractant instead of the very expensive trimedlure, normally used for this purpose. Open field test should be conduced to complete the evaluation of basil oil as a medfly attractant

    With the increasing popularity of cardiac ablation therapy, studies of the procedural effects on left atrial and pulmonary vein morphology are becoming more important. Of particular interest is evaluation of atrial and pulmonary vein remodeling following ablation therapy using structural imaging. One challenge that arises when comparing pulmonary vein morphology across subjects is defining the ostial location. Strategies for defining this important anatomical location include volume renderings from multiple angles, or drawing lines in cross-sectional images. Drawbacks of these techniques include subjectivity between raters as well as limited use of three dimensional volumetric information. In this work, we describe a method for automatically identifying the pulmonary vein ostia from CT images using a single user selected seedpoint. The technique makes use of the full three dimensional volumetric information, by computing a centerline along each pulmonary vein and defining the ostium using oblique cross-sectional image planes along the curve axis. The ostium is defined as the point at which there is a spike in the oblique cross-sectional area. The method is demonstrated on each of the four pulmonary veins in four patient datasets, for a total of sixteen applications of the algorithm. The results are compared against manual delineations of the pulmonary vein ostia, with overall mean distances ranging from approximately 1.5 to 5.0 mm. In conclusion, although the pulmonary veins exhibit variable anatomic shapes and orientations across different patient datasets, our proposed automated method produces results comparable to manual delineation of the ostia.

    Venous bypass grafts often fail following arterial implantation due to excessive smooth muscle cells (VSMC) proliferation and consequent intimal hyperplasia (IH). Intercellular communication mediated by Connexins (Cx) regulates differentiation, growth and proliferation in various cell types. Microarray analysis of vein grafts in a model of bilateral rabbit jugular vein graft revealed Cx43 as an early upregulated gene. Additional experiments conducted using an ex-vivo human saphenous veins perfusion system (EVPS) confirmed that Cx43 was rapidly increased in human veins subjected ex-vivo to arterial hemodynamics. Cx43 knock-down by RNA interference, or adenoviral-mediated overexpression, respectively inhibited or stimulated the proliferation of primary human VSMC in vitro. Furthermore, Cx blockade with carbenoxolone or the specific Cx43 inhibitory peptide 43gap26 prevented the burst in myointimal proliferation and IH formation in human saphenous veins. Our data demonstrated that Cx43 controls proliferation and the formation of IH after arterial engraftment. PMID:26398895

    Full Text Available Deep vein thrombosis is a common disease among Caucasians but is rare in Asia.Venous thrombosis may be fatal, for example by a pulmonary embolism and right or leftatrial thrombosis. Alternatively, deep vein thrombosis may follow a benign pattern such asfemoral and popliteal vein thrombosis. Theories abound regarding the causes of deep veinthrombosis, with the most common theories being long-term stasis and lack of exercise.Internal jugular vein thrombosis is a rare but potentially fatal disease with various causes. Inthe pre-antibiotics era, this disease was frequently associated with deep neck infection.Recently however, local trauma, central catheterization, and repeated intravenous injectionswith drugs have become the leading causes of thrombosis. Spontaneous internal jugularvein thrombosis may occur in connection with a neoplasm, termed Trousseau's syndrome.This investigation reports a case of lung cancer associated with internal jugular vein thrombosis.

    Portal vein thrombosis (PVT) is considered to be a frequent complication of liver cirrhosis. However, unlike PVT in patients without cirrhosis, very few data are available on the natural history and management of PVT in cirrhosis, despite its association with potentially life-threatening conditions, such as gastroesophageal bleeding and acute intestinal ischemia. Moreover, no consensus regarding PVT in cirrhosis exists. Suggested causes of PVT in cirrhosis include reduced portal blood flow velocity, multiple congenital or acquired thrombophilic factors, inherited or acquired conditions, and derangement of liver architecture. However, the understanding of PVT in cirrhosis is incomplete. In addition, information on the management of PVT in cirrhosis is inadequate. The aims of this review are to: (1) assemble data on the physiopathological mechanism, clinical findings, diagnosis and management of PVT in cirrhosis; (2) describe the principal factors most frequently involved in PVT development; and (3) summarize the recent knowledge concerning diagnostic and therapeutic procedures.

  4. On the dragnosis of deep vein thrombosis

    International Nuclear Information System (INIS)

    Clinical and laboratory diagnostic methods were studied in 301 consecutive patients with suspected deep vein thrombosis (DVT). Unexpectedly, phlebography (the reference method) was found to cause DVT in estimated 48 % of patients without initial DVT. Using a new type of contrast medium, however, no thrombotic complications were found. - Neither clinical examination nor plethysmography were found to give reliable results. Using a modified technique for radioisotope detection, high sensitivity to DVT was found with the 125I-fibrinogen uptake test (within 2 days) and a newly developed 99Tcsup(m)-plasmin test (within one hour). Since both tests showed low specificity, they are reliable as screening tests to exclude DVT, but not as independent diagnostic methods. (author)

    Full Text Available A 56-year-old male patient presented with a complaint of two painful, hard, palpable nodules in the right lower limb. A Doppler ultrasound scan revealed the presence of nodules, likely to be neoplastic. Computed angiography showed two solid hypervascular nodules in the right great saphenous vein, fed by branches of the posterior tibial artery. Embolization of the nodules using surgical cyanoacrylate was performed, followed by an excisional biopsy. Anatomical pathology and immunohistochemical analysis identified the nodule as a high-grade leiomyosarcoma, characterized by ten mitotic figures per ten high-power fields, necrosis and cell pleomorphism. Immunohistochemical analysis results were positive for caldesmon and desmin labeling. A second surgical procedure was performed to enlarge the free margins.

    Given their frequent use as bypass conduits and high rates of degeneration, saphenous vein grafts (SVGs) will continue to require percutaneous coronary intervention. Due to their unique physiology, SVGs pose special challenges to the interventionalist. Preintervention evaluation of hemodynamic significance is hampered by limited data and uncertainty regarding the validity of fractional flow reserve. Intraprocedural complications, particularly distal embolization and no-reflow, are common but may be mitigated by various techniques. Despite advances in the field, SVG intervention is associated with worse outcomes - including increased rates of periprocedural myocardial infarction, restenosis, target vessel revascularization, non-target disease progression, and death - compared with native vessel intervention. This paper reviews the most recent data and techniques available to the interventionalist seeking to improve outcomes after SVG intervention. PMID:25480996

    The paper reviews the actual therapeutical means in a severe invalid eye disease. The treatment is not able to improve the retinal blood flow, being more effective on the main symptoms and complications. The isovolumetric hemodilution method as an up-to-date method in the treatment of central retinal vein occlusion, appears to bring better recuperation hopes, by a higher improvement of the local anatomical and hemodynamical factors. That is the reason why we shall expose it widely in our paper. Unfortunately, despite its complexity, the treatment of central retinal vein occlusion is not satisfactory from the point of view of the high number of patients that remain with a low visual acuity. The main goal of the therapy is the recovery of visual function, but a few aspects and especially the late presentation for ophthalmological examination, reduce the objective of treatment to prevent complications.

    The ability to maintain and respond to challenges to homeostasis is primarily a function of the autonomic nervous system (ANS). In infants with complex congenital heart defects this ability may be impaired. This study described change in ANS function before and after surgical correction in infants with transposition of the great arteries (TGA) and in healthy infants. A total of 15 newborn infants with TGA were matched with 16 healthy infants on age, gender, and feeding type. The ANS function was measured using heart rate variability (HRV). Data were collected preoperatively in the 1st week of life and postoperatively before, during, and after feeding at 2 weeks and 2 months of age. Infants with TGA demonstrated significantly lower high-frequency and low-frequency HRV preoperatively (p nursing interventions supportive of these high-risk infants. PMID:21613339

    This article describes a part of the interview process that is never usually reported. Listening to what people say is the key to increasing our knowledge of human existences. Procuring knowledge about human experience is much more challenging. Although good sources on how to prepare and conduct an interview exist, the process of the interviewer's perception of the interviewee's message and meaning is less examined. Beyond the role of eliciting the data, the researcher endeavours to reproduce the interviewee's narration and not the voice of the researcher.

    2010-01-01

    Science museums define the objectives of their exhibitions in terms of visitor learning outcomes, yet exhibition engineering staff lack theoretical and empirical research findings on which to base the creation of these educational environments. Here, a first step towards providing such research is reported. Museographic transposition was used as an analytical framework to investigate the development of an existing museum exhibit on animal adaptations to darkness. The analysis yielded a descriptive model of exhibition engineering as a three-stage process in which simultaneous processes of epistemological development and museum-pedagogical development result in the curatorial brief which forms the basis of the subsequent museographic development of the physical exhibit. Examples are discussed which illustrate the use of the model in identifying exhibition inconsistencies, but also in generating new ideas for exhibition engineering. The potential for further developing the model is discussed.

    In toe desyndactyly, a dorsal or plantar commissural flap, combined with skin grafts, will ensure an acceptable result. However, the parallel unsightly scars in the longitudinal direction on the dorsum of the toes will sometimes fail to satisfy the patient's and/or the parents' aesthetic expectations. To address this issue, we developed a technique using a transversely oriented transposition flap for web reconstruction, which can spare the dorsal interdigital skin maximally to shift the dorsal scars plantarly such that they become inconspicuous. The design of the flap is simple and uncomplicated surgically. Moreover, the donor site morbidity is minimal, owing to the good healing potential of the transverse scars. This technique could be an alternative in web reconstruction of toe desyndactyly, especially in cases with high cosmetic priority. PMID:25998477

  12. Grasping the experience of the other from an interview: : Self-transposition in use

    This article describes a part of the interview process that is never usually reported. Listening to what people say is the key to increasing our knowledge of human existences. Procuring knowledge about human experience is much more challenging. Although good sources on how to prepare and conduct an interview exist, the process of the interviewer’s perception of the interviewee’s message and meaning is less examined. Beyond the role of eliciting the data, the researcher endeavours to reproduce the interviewee’s narration and not the voice of the researcher. By illustrating the process during the interview, further transparency and thereby validity may be achieved. To exemplify this, the perception of the interviewer is explored, and here Heidegger’s work on self-transposition has proved to be helpful.

    Persistent pulmonary hypertension of the newborn (PPHN) occurs in 1-4% of neonates with transposition of the great arteries with intact ventricular septum (TGA/IVS). This association is often lethal. To our knowledge, only eight survivors have been described in the literature, two of whom benefited from extracorporeal membrane oxygenation (ECMO). We report two cases of PPHN complicating a TGA/IVS that were refractory to multiple therapies and resolved 48 hours after initiation of bosentan therapy. Bosentan, an oral dual endothelin-1 receptor antagonist, is a new treatment for pulmonary arterial hypertension that was both effective and safe in these two cases of TGA/IVS with PPHN. To our knowledge, it is the first use of bosentan in newborns. PMID:17701214

    This review article describes our recent efforts to develop environmentally benign transformations of allyl and propargyl alcohols via the 1,3-transposition of their hydroxyl groups using combined catalyst systems. This methodology allows for successful transformation under mild conditions, which has never been achieved using each catalyst. Representative examples of this methodology include the following three reactions. First, the combination of oxo-vanadium compounds and lipases resulted in the dynamic kinetic resolution of racemic allyl alcohols to give optically active allyl esters in high yields. Second, Mo-Au-Ag combination catalysis dramatically accelerated the rearrangement of diverse propargyl alcohols into ?,?-unsaturated carbonyl compounds. Finally, the choice of suitable heteropoly acids for the rearrangement of propargyl alcohols led to the selective preparation of both (Z)- and (E)-enones. PMID:21963972

  15. MRI of the pulmonary artery after arterial switch operation for transposition of the great arteries

    International Nuclear Information System (INIS)

    Twenty-six children who underwent an arterial switch operation for transposition of the great arteries were examined with MRI and Doppler ultrasound (US). The aim was to determine the capability of MRI for detecting a possible stenosis of the pulmonary arteries. In 10 children angiocardiography (ACG) was done after the MRI examination. Using ACG as the gold standard, MRI was sensitive in the detection of pulmonary artery stenosis. MRI was more precise in the localization of a stenosis than was Doppler US. Right ventricular hypertrophy was a sensitive indicator of pulmonary artery stenosis. These results suggest that MRI could serve as a screening examination for pulmonary artery stenosis after an arterial switch operation. (orig.)

    Transposition of the great arteries (TGA) refers to hearts with concordant atrioventricular connections but discordant ventriculoarterial connections. In this lesion, the aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. As such, the pulmonary and aortic circulations run in parallel as opposed to in series, and this lesion is not compatible with survival without adequate mixing of these circulations. The management and outcomes of TGA parallels the field of pediatric cardiac surgery itself. Uniformly fatal in childhood, palliative procedures from the 1950s to 1970s offered survival, albeit at a high early and late cost. In the 1970s, the arterial switch operation (ASO) provided an anatomical "cure," with survival to adulthood in the current era of around 90%. Detailed perioperative imaging, attention to associated lesions, and comprehension of the physiology are critical to medical and surgical management. PMID:25900899

    Full Text Available Modern greenhouse production has been ~100% reliant on fossil fuels for all inputs (glazing, heating, fertilization, lighting, post-harvest. Recent innovations may reduce fossil fuel dependence but their effectiveness may not be thoroughly tested. To promote education in sustainable production, undergraduate students in Greenhouse Management class (Hort 3002W; University of Minnesota tested the effectiveness of two organic or ‘sustainable’ soilless media (Sunshine Natural and Organic Growing Mix, Sungro Metro-Mix Special Blend with a control (Sunshine LC8 Professional for crop production (height, leaf/flower number, yield and sensory evaluations (appearance, texture, taste, purchase of cucumbers (‘Big Burpless Hybrid’, ‘Sweet Burpless Hybrid’, basil (‘Opal Purple’, ‘Redleaf’, parsley (‘Green River’, ‘Extra Curled Dwarf’, ‘Hamburg’, and lettuce (Flying Saucer ‘Green’, ‘Red’. Significant differences between sustainable vs. control soils occurred for plant growth, depending on vegetative or reproductive traits, crops, and cultivars. These differences occasionally disappeared for sensory evaluation of edible components. In most crops, however, cultivars were highly significant factors. Undergraduate research can be used to provide directionality for future vegetable and herb plant breeding to focus on creating cultivars with increased yield and high consumer acceptance when grown in sustainable greenhouse soilless mixes.

    Leaf venation is diverse across plant species and has practical applications from paleobotany to modern agriculture. However, the impact of vein traits on plant performance has not yet been tested in a model system such as Arabidopsis thaliana. Previous studies analysed cotyledons of A.?thaliana vein mutants and identified visible differences in their vein systems from the wild type (WT). We measured leaf hydraulic conductance (Kleaf ), vein traits, and xylem and mesophyll anatomy for A.?thaliana?WT (Col-0) and four vein mutants (dot3-111 and dot3-134, and cvp1-3 and cvp2-1). Mutant true leaves did not possess the qualitative venation anomalies previously shown in the cotyledons, but varied quantitatively in vein traits and leaf anatomy across genotypes. The WT had significantly higher mean Kleaf . Across all genotypes, there was a strong correlation of Kleaf with traits related to hydraulic conductance across the bundle sheath, as influenced by the number and radial diameter of bundle sheath cells and vein length per area. These findings support the hypothesis that vein traits influence Kleaf , indicating the usefulness of this mutant system for testing theory that was primarily established comparatively across species, and supports a strong role for the bundle sheath in influencing Kleaf .

    Full Text Available To compare prospective between insertion of non-cuffed dual lumen catheter in the external jugular vein and other central veins for hemodialysis (HD, we studied 68 chronic dialysis patients randomly allocated into two groups: one with external jugular vein catheterization as access for HD and another with other central venous catheterization, internal jugular or subclavian vein. Our results showed there were no significant differences regarding successful cannulation, com-plications, total numbers of dialysis, development of pain and infection at the site of cannulation, patency rate of the catheters, and efficacy of hemodialysis between both groups. In addition, the patency of the catheter in the external jugular vein was not affected by previous cannulation of other central veins. In contrast, there was a significant correlation between numbers of attempts for cannulation in both groups and development of hematoma and infection, (p< 0.05. In conclusion, our results showed that the external jugular vein may be an alternative for other central veins for insertion of temporary non-cuffed hemodialysis catheter.

    The aims of this study were to assess the development of heart failure in patients with congenitally corrected transposition of the great arteries in a medium-term follow-up, to identify the impact of tricuspid regurgitation on the development of heart failure, and to determine the most reliable marker for its identification. The prospective 6-year follow-up study included 19 adult patients. All patients were evaluated clinically by the determination of N-terminal pro-hormone brain natriuretic peptide levels, exercise stress testing, echocardiography magnetic resonance, or CT. Among them, two patients died of heart failure. There was a decline in exercise capacity and systolic systemic ventricular function (p=0.011). Systemic ventricular ejection fraction decreased (48.3±13.7 versus 42.7±12.7%, p=0.001). Tissue Doppler imaging showed a decline in peak tricuspid systolic annular velocity (10.3±2.0 versus 8.3±2.5 cm/second, p=0.032) and peak tricuspid early diastolic annular velocity (14.6±4.3 versus 12.0±4.5 cm/second, p=0.048). The tricuspid regurgitation did not increase significantly. N-terminal pro-hormone brain natriuretic peptide levels increased (127.0 ng/L(82.3-305.8) versus 226.0 ng/L(112.5-753.0), p=0.022). Progressive exercise intolerance in congenitally corrected transposition of the great arteries appears to be driven mainly by a progression in systemic right ventricular dysfunction. Tricuspid regurgitation is likely to play a role, especially in patients with structural abnormalities of the tricuspid valve - Ebstein anomaly. The N-terminal pro-hormone brain natriuretic peptide levels and tissue Doppler parameters appear sensitive in detecting changes over time and may guide management. PMID:25522750

    Full Text Available Objective: 1. Follow-up data of patients with simple transposition of great arteries (TGA and TGA with ventricular septal defect (VSD, who had arterial switch operation (ASO are compared. 2. Factors affecting mortality and morbidity after ASO are described.Methods: Seventy-six patients, who had an ASO between April 2007 and August 2010 were studied retrospectively. The patients with intact ventricular septum (IVS (n=36 were in Group1, and those with VSD (n=40 in Group 2. The pre and postoperative clinical and echocardiographic variables and intensive care unit (ICU outcomes were compared among groups using Mann-Whitney U, Pearson correlation and logistic regression tests.Results: The mean age at operation was 44.1 days, weight was 3.6±0.98 kg. Patients were followed for 15.5±11.21 months. The aortic cross-clamp (AoCC and cardiopulmonary bypass (CPB times were higher in patients with VSD (p=0.001, p=0.004. Patients in Group 1 had longer inotropic agent infusion (p=0.001. Length of stay in ICU was similar in two groups (p>0.05. There was no correlation between the length of stay in ICU and age, weight, CPB time, AoCC time. Aortic regurgitation was more frequent in Group 2 (p=0.02. During follow-up, 12 patients died (15.7%, and 8 patients had a revision operation (10.5% (diaphragmatic plication in 4, pulmonary artery reconstruction in 1, recoarctation operation in 3 patients. Mortality was similar in groups (p>0.05.Conclusion: Arterial switch operation provides anatomical correction in TGA. Appropriate timing and good perioperative planning facilitates low morbidity and mortality in patients with VSD as in patients with simple TGA.

MATERIALS AND METHODS: One hundred male adult cadavers and 24 fetuses were studied. Four anatomic aspects were considered: 1 Number of testicular veins, 2 The local of vein termination, 3 Type and number of collaterals present and 4 Testicular vein termination angle. RESULTS: Cadavers - Right side - One testicular vein occurred in 85% and 2 veins in 5% of the cases. There were communicating veins with the colon in 21% of the cases. Left side - One testicular vein occurred in 82%, two veins in 15%, three veins in 2% and four veins in 1% of the cases. There were communicating veins with the colon in 31% of the cases. Fetuses - Right side -One testicular vein occurred in all cases. This vein drained to the vena cava in 83.3% of the cases, to the junction of the vena cava with the renal vein in 12.5% and to the renal vein in 4.2%. There were communicating veins with the colon in 25% of the cases. Left side - One testicular vein occurred in 66.6% of the cases, and 2 veins in occurred 33.3%. Communicating veins with the colon were found in 41.6% of the cases. CONCLUSION: The testicular vein presents numeric variations and also variations in its local of termination. In approximately 30% of the cases, there are collaterals that communicate the testicular vein with retroperitoneal veins. These anatomic findings can help understanding the origin of varicocele and its recurrence after surgical interventions.

    Prenatal diagnosis of D-transposition of the great arteries remains less frequent compared to other major congenital heart defects. In this study, we examined how often the 3-vessel and trachea view was abnormal in a large series of prenatally diagnosed cases of D-transposition of the great arteries. We found that an abnormal 3-vessel and trachea view in the shape of an "I" ("I-sign"), which represents an anteriorly displaced aorta, was present in all fetuses with D-transposition of the great arteries when a 3-vessel and trachea view was successfully obtained. Therefore we believe that the 3-vessel and trachea view can be used to reliably detect D-transposition of the great arteries during prenatal sonography. PMID:26112638

    Full Text Available Leaf features play an important role in plant species identification and plant taxonomy. The type of the leaf vein is an important morphological feature of the leaf in botany. Leaf vein should be extracted from the leaf in the image before discriminating its type. In this paper a new method of leaf vein extraction has been proposed based on gray-scale morphology. Firstly, the color image of the plant leaf is transformed to the gray image according to the hue and intensity information. Secondly, the gray-scale morphology processing is applied to the image to eliminate the color overlap in the whole leaf vein and the whole background. Thirdly, the linear intensity adjustment is adopted to enlarge the gray value difference between the leaf vein and its background. Fourthly, calculate a threshold with OSTU method to segment the leaf vein from its background. Finally, the leaf vein can be got after some processing on details. Experiments have been conducted with several images. The results show the effectiveness of the method. The idea of the method is also applicable to other linear objects extraction.

  17. Anatomical Variation in the Origin of Portal Vein: Case Report.

    Full Text Available The portal vein (PV is a large vessel which arises from the union of the lienic vein with the superior mesenteric vein. Their variations are rare, however it must be remembered during pancreaticoduodenal surgeries. This paper aims to describe the anatomical variation of the PV origin during a cadaveric dissection.33 dissections of cadavers of both sexes were performed, 28 of them were male and 5 female, all over 18 years old, both fresh and fixed in 10% formalin. It was performed an evisceration of all of them, with the purpose of performing the dissection of the pedicles of the various organs of the cadaver.Of the 33 cadavers, 11 were fresh and 22 were formalin-fixed, during dissection of a block of fresh viscera from the supramesocolic level from a male, specifically at the lower edge of the body of the pancreas, there was an anatomical variation of PV origin. This variation was in absence of superior mesenteric vein, replaced by the gastrocolic venous trunk which joins with the venous trunk formed by the junction of the ileocolic and splenic veins. The inferior mesenteric vein joins with splenic vein.The knowledge of anatomical variations of the PV is fundamental in the clinical-surgical field to reduce potential intraoperative injuries (bleeding and postoperative complications in pancreatic and colon surgery.

    Full Text Available AIM: To investigate the effects of antithrombin III (AT III injection via the portal vein in acute liver failure. METHODS: Thirty rats were intraperitoneally challenged with lipopolysaccharide (LPS and D-galactosamine (GalN and divided into three groups: a control group; a group injected with AT III via the tail vein; and a group injected with AT III via the portal vein. AT III (50 U/kg body weight was administrated 1 h after challenge with LPS and GalN. Serum levels of inflammatory cytokines and fibrin degradation products, hepatic fibrin deposition, and hepatic mRNA expression of hypoxia-related genes were analyzed. RESULTS: Serum levels of alanine aminotransferase, tumor necrosis factor-? and interleukin-6 decreased significantly following portal vein AT III injection compared with tail vein injection, and control rats. Portal vein AT III injection reduced liver cell destruction and decreased hepatic fibrin deposition. This treatment also significantly reduced hepatic mRNA expression of lactate dehydrogenase and heme oxygenase-1. CONCLUSION: A clinically acceptable dose of AT III injection into the portal vein suppressed liver damage, probably through its enhanced anticoagulant and anti-inflammatory activities.

  1. Transposon Tn7 Directs Transposition into the Genome of Filamentous Bacteriophage M13 Using the Element-Encoded TnsE Protein?

    OpenAIRE

    Finn, Jessica A.; Parks, Adam R.; Peters, Joseph E

    2007-01-01

    The bacterial transposon Tn7 has a pathway of transposition that preferentially targets conjugal plasmids. We propose that this same transposition pathway recognizes a structure or complex found during filamentous bacteriophage replication, likely by targeting negative-strand synthesis. The ability to insert into both plasmid and bacteriophage DNAs that are capable of cell-to-cell transfer would help explain the wide distribution of Tn7 relatives.

  2. New approaches for the treatment of varicose veins.

    Teruya, Theodore H; Ballard, Jeffrey L

    2004-10-01

    New, minimally invasive techniques for the treatment of varicose veins including radiofrequency ablation (RFA), endovenous laser therapy (EVLT), and transilluminated power phlebectomy (TIPP) represent effective and possibly superior alternatives to traditional saphenous vein stripping and stab avulsion of varicose veins. Further experience with these procedures will help to determine which ones will become the method of choice for treating this complex disease process. Some of these new techniques may not prove to be effective in the hands of all treating specialists. However,it is very likely that some of these techniques, such as foam sclerotherapy and RFA, will replace the procedures that we currently use today. PMID:15364562

    Full Text Available Use of a temporary central venous catheter is common practice in hemodialysis therapy. One of the most common complications of central venous catheterization is catheter malposition. Cannulation of the azygos vein (particularly the azygos arch is a rare but hazardous catheter malposition that carries a substantial risk of perforation, thrombosis and vascular stenosis. On the other hand, the azygos vein can be used for vascular access in patients whose superior vena cava and inferior vena cava are thrombosed. We present a case where the required blood flow for hemodialysis was provided by a dilated azygos vein due to superior vena cava obstruction.

  4. Formation of the external jugular vein in the brown brocket deer (Mazama gouazoubira

    Full Text Available The brown brocket deer (Mazama gouazoubira is a brown-greyish short-haired wild ruminant living in Central and South Americas. This paper aimed at describing the formation of the external jugular vein in a male specimen which died due to run-over. The facial and cervical regions were dissected so as to allow the visualization of the external jugular vein and its tributaries. This vein was formed by the union of the maxillary and linguofacial veins. The first originated from the superficial and transverse facial temporal veins, and it received along its length the angular vein of the eye, as well as the dorsal and lateral veins of the nose and upper lip. The second was formed after the anastomosis of the lingual and facial veins. The facial vein was originated by the union of the lower lip and deep facial veins, in the middle third of the face, rostral to the masseter muscle. This vascular arrangement differs from that usually observed in domestic ruminants, in which the transverse facial vein is underdeveloped and the facial vein receives the angular vein of the eye, the dorsal and lateral veins of the nose, besides the upper lip vein. The external jugular vein in the brown brocket deer presented the same tributaries than domestic ruminants, however, with a different vessel arrangement of the facial and facial transverse veins.

    1995-10-01

    2D time-of-flight MR venography (2D TOF MRV) was performed in 16 patients (25 calves) with varicose veins and 2 volunteers (4 calves), and compared with venography. Sequential SPGR (TR/TE/FA=45 ms/7 ms/60deg) transverse images and/or GRASS (TR/TE/FA=100 ms/13 ms/60deg) transverse images were obtained for MRV. Superior presaturation pulse (S-SAT) was placed in 21 calves, and 0.05 mmol/kg Gd-DTPA was used in all calves. Projection MRVs were generated with maximum intensity projection (MIP) reconstruction. Regarding sequence parameter, S-SAT was useful to eliminate signal from artery that would obscure the signal of deep veins. The detectability of deep veins was improved with the use of S-SAT. In the comparison with venography, MRV could more clearly demonstrate varicose veins more than 5 mm in diameter and their drainage veins than venography. But it could not so clearly demonstrate deep veins as venography. It could not detect fine varicose veins less than 5 mm in diameter and connecting veins with valve insufficiency. In the examination of varicose veins, detection of deep veins, large varicose veins and their main drainage veins is clinically important, because diagnosis of patency of deep veins and dilatation of the drainage veins is necessary to choose the treatment, concluding conservative therapy, stripping and sclerotherapy. However, detection of fine varicose veins and connecting veins are not so important because those veins seldom need treatment. MRV was not so suitable for detection of deep veins, but very useful for detection of varicose veins more than 5 mm in diameter and their main drainage veins. In conclusion, MRV is non-invasive and effective method in varicose veins of calf, and it can take the place of venography with the improvement of deep vein detectability. (author).

  6. Brief communication: Additional cases of maxillary canine-first premolar transposition in several prehistoric skeletal assemblages from the Santa Barbara Channel Islands of California.

    2010-09-01

    This article identifies and discusses seven new cases of complete maxillary canine-premolar transposition in ancient populations from the Santa Barbara Channel region of California. A high frequency of this tooth transposition has been previously documented within a single prehistoric cemetery on one of the Channel Islands. A total of 966 crania representing 30 local sites and about 7,000 years of human occupation were examined, revealing an abnormally high prevalence of this transposition trait among islanders during the Early period of southern California prehistory ( approximately 5500-600 B.C.). One of the affected crania is from a cemetery more than 7,000-years-old and constitutes the earliest case of tooth transposition in humans so far reported. The results are consistent with findings by other studies that have indicated inbreeding among the early Channel Islands groups. Together with the normal transposition rates among mainland populations, the decreasing prevalence of maxillary canine-first premolar transposition among island populations across the Holocene suggests that inbreeding on the northern Channel Islands had all but ceased by the end of the first millennium B.C., most likely as a result of increased cross-channel migration and interaction.

    Bright linear features about the width of a human thumb that were found on Mars by NASA's Mars Exploration Rover Opportunity appear to be gypsum veins deposited by groundwater, a team of scientists announced at a 7 December news briefing at the AGU Fall Meeting in San Francisco, Calif. “To me, this is the single most powerful piece of evidence for liquid water on Mars that has been discovered by the Opportunity rover,” said Steve Squyres, a geoscientist at Cornell University in Ithaca, N. Y., and principal investigator for NASA Mars Exploration Rovers Opportunity and Spirit. “We have found sulfates before. Those sulfates were formed somewhere; we don't know where. They have been moved around by the wind, they've been mixed with other materials. It's a big, jumbled, fascinating mess. This stuff was formed right here. There was a fracture in the rock, water flowed through it, gypsum was precipitated from the water. End of story. Okay, there is no ambiguity about this. This is what makes it so cool.”

  8. A new beginning: nursing care of the infant undergoing the arterial switch operation for transposition of the great arteries.

    Transposition of the great arteries is a common form of cyanotic congenital heart disease that without intervention has a 90% mortality rate within the first year of life. In the past, surgical options were limited to physiologic correction at the atrial level, but long-term follow-up has revealed problems with right ventricular dysfunction, tricuspid valve insufficiency, arrhythmias, and venous obstruction. This has renewed an interest in the arterial switch as an early, definitive form of anatomic correction for infants with transposition. As selection criteria have been refined, the mortality rate at experienced centers now equals that of physiologic correction. Nursing care centers around the critically ill neonate who may have hypotension and low cardiac output because of a poorly adapted left ventricle. Assessment for potential myocardial infarction resulting from movement and reimplantation of the coronary arteries is essential. PMID:2470699

    Although mortality rates for patients with d-transposition of the great arteries remain quite low, these patients have a unique circulation that requires careful management in the peri-operative period. Despite the improved mortality for patients with common arterial trunk, the course in the intensive care unit is remarkable for significant morbidity and utilisation of significant resources. Pre-operative patient management focuses on balancing competing circulations, pulmonary and systemic, which exist in parallel rather than in series, as in the normal circulation. Post-operative patient management in both lesions focuses on optimising systemic output, respiratory status, and mitigating the effects of cardiopulmonary bypass. In this article, we review pre- and post-operative intensive care management in neonates with d-transposition of the great arteries and common arterial trunk. PMID:23331599

    The effects of flaxseed, sardines, pearl millet, and holy basil (Oscimum sanctum) leaf meal on Single Comb White Leghorn (Forsgate strain) layer hen production traits, fatty acid composition of egg yolks, and egg quality characteristics were studied. Layer hens were allocated to 1 of 6 dietary treatments from 27 to 32 wk of age: control (treatment 1), control + 1 g of basil leaf meal (BLM) (treatment 2), control + 2 g of BLM (treatment 3), designer egg layer mash (DELM; treatment 4), DELM + 1 g of BLM (treatment 5), DELM + 2 g of BLM (treatment 6). No significant differences were found in egg production between dietary treatments, indicating that neither the designer diet nor the BLM had an adverse effect on egg production. The high energy level in the designer diet, because of the flaxseed oil and sardines, significantly reduced feed intake compared with the control diet. The egg weight was significantly higher in birds fed the designer diet compared with the egg weight in the control diet. The flaxseed oil and sardine oil, which are rich in n-3 polyunsaturated fatty acids, contributed to significantly increased n-3 polyunsaturated fatty acid levels in the egg yolks, with a proportionate reduction in the level of palmitic acid. Other fatty acids showed only minor variations. Flaxseed oil increased the level of ?-linolenic acid, whereas fish oil increased the eicosapentaenoic acid and docosahexaenoic acid levels. The BLM at low levels of inclusion (1 and 2 g/kg) also contributed significantly to elevating the yolk n-3 polyunsaturated fatty acid levels, especially C18:3. Holy basil leaf meal is a good feed supplement for increasing the yolk ?-linolenic acid level by reducing the yolk saturated fatty acid levels proportionately. PMID:21177454

    2008-10-01

    alpha-Zingiberene synthase (ZIS), a sesquiterpene synthase gene that was isolated from lemon basil (Ocimum basilicum L.), encodes an enzyme that catalyzes the formation of alpha-zingiberene, and other sesquiterpenes, from farnesyl diphosphate. Transgenic tomato fruits overexpressing ZIS under the control of the fruit ripening-specific tomato polygalacturonase promoter (PG) accumulated high levels of alpha-zingiberene (224-1000 ng g(-1) fresh weight) and other sesquiterpenes, such as alpha-bergamotene, 7-epi-sesquithujene, beta-bisabolene and beta-curcumene, whereas no sesquiterpenes were detected in non-transformed control fruits. The ZIS-transgenic fruits also produced monoterpenes, such as alpha-thujene, alpha-pinene, beta-phellandrene and gamma-terpinene (1-22 ng g(-1) fresh weight), which were either not detected or were found only in minute concentrations in control fruits. Recombinant ZIS overexpressed in Escherichia coli catalyzed the formation of these monoterpenes from geranyl diphosphate. As the ZIS protein apparently lacks a transit peptide, and is localized in the cytosol, the production of monoterpenes in the transgenic tomatoes suggests that a pool of geranyl diphosphate is available in the cytosol. The phenotype of the ZIS-transgenic tomatoes was the same as that for wild-type tomatoes, with regard to plant vigor and shape, but transgenic plants exhibited a small decrease in lycopene content. This study thus showed that the synthesis of both mono- and sesquiterpenes can be enhanced by the ectopic expression of a single transgene in tomato fruit, and it further demonstrated the interconnection between the pools of terpenoid precursors in the plastids and the cytosol.

    DNA 5-methylcytosine (5-meC) is an important epigenetic mark for transcriptional gene silencing in many eukaryotes. In Arabidopsis, 5-meC DNA glycosylase/lyases actively remove 5-meC to counteract transcriptional gene silencing in a locus-specific manner, and have been suggested to maintain the expression of transposons. However, it is unclear whether plant DNA demethylases can promote the transposition of transposons. Here we report the functional characterization of the DNA glycosylase/lyas...

    Tn10/IS10 transposition takes place in the context of a protein–DNA complex called a transpososome. During the reaction, the transpososome undergoes several conformational changes. The host proteins IHF and H-NS, which also are global regulators of gene expression, play important roles in directing these architectural changes. IHF binds tightly to only one of two transposon ends within the transpososome, folding this end into a DNA loop structure. Unfolding this DNA loop is necessary for exci...

    Full Text Available Objectives: This article, the second in a two-part series, continues the discussion of inferior alveolar nerve lateralization/transposition for dental implant placement. The aim of this article is to review the scientific literature and clinical reports in order to analyse the neurosensory complications, risks and disadvantages of lateralization/transposition of the inferior alveolar nerve followed by implant placement in an edentulous atrophic posterior mandible. Material and Methods: A comprehensive review of the current literature was conducted according to the PRISMA guidelines by accessing the NCBI PubMed and PMC databases, as well as academic sites and books. The articles were searched from January 1997 to July 2014. Articles in English language, which included adult patients between 18 - 80 years of age who had minimal residual bone above the mandibular canal and had undergone inferior alveolar nerve (IAN repositioning, with minimum 6 months of follow-up, were included. Results: A total of 21 studies were included in this review. Ten were related to IAN transposition, 7 to IAN lateralization and 4 to both transposition and lateralization. The IAN neurosensory disturbance function was present in most patients (99.47% [376/378] for 1 to 6 months. In total, 0.53% (2/378 of procedures the disturbances were permanent. Conclusions: Inferior alveolar nerve repositioning is related to initial transient change in sensation in the majority of cases. The most popular causes of nerve damage are spatula-caused traction in the mucoperiosteal flap, pressure due to severe inflammation or retention of fluid around the nerve and subsequent development of transient ischemia, and mandibular body fracture.

    2015-09-01

    Results: In the present study, normal azygos venous system was found in 8 specimens accounting for 80%. Variations were found in 2 specimens (20%; one specimen presented with connection between accessory hemiazygos vein and hemiazygos vein, 3 transverse channels across vertebral column and the other specimen showed absence of accessory hemiazygos vein and shifting of azygos vein towards midline. Conclusions: Accurate knowledge about these kinds of variations is very important to identify, especially in the computed tomography and magnetic resonance imaging of mediastinum. The abnormal azygos venous system may easily be confused with aneurysm, lymphadenopathy and other abnormalities like tumor. It is important to keep these kinds of variations in mind while performing the mediastinal operations or surgery of large vessels. [Int J Res Med Sci 2015; 3(9.000: 2323-2326

    Plantar vein thrombosis is a rare condition, with only a handful of cases reported in the literature. The cause is unknown; however, the disease has been attributed to prior surgery, trauma, and paraneoplastic conditions. We present a case of a 32-year-old female runner with plantar vein thrombosis diagnosed on contrast-enhanced MRI and confirmed on ultrasound. The symptoms resolved with conservative treatment and evaluation revealed the presence of a prothrombin gene mutation and use of oral contraceptive pills. To our knowledge, this is the first case of plantar vein thrombosis diagnosed initially by MRI. Moreover, this case suggests that plantar vein thrombosis should be considered in patients with hypercoagulable states and plantar foot pain. (orig.)

  12. Finger Vein Recognition Based on Local Directional Code

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available Finger vein patterns are considered as one of the most promising biometric authentication methods for its security and convenience. Most of the current available finger vein recognition methods utilize features from a segmented blood vessel network. As an improperly segmented network may degrade the recognition accuracy, binary pattern based methods are proposed, such as Local Binary Pattern (LBP, Local Derivative Pattern (LDP and Local Line Binary Pattern (LLBP. However, the rich directional information hidden in the finger vein pattern has not been fully exploited by the existing local patterns. Inspired by the Webber Local Descriptor (WLD, this paper represents a new direction based local descriptor called Local Directional Code (LDC and applies it to finger vein recognition. In LDC, the local gradient orientation information is coded as an octonary decimal number. Experimental results show that the proposed method using LDC achieves better performance than methods using LLBP.

  13. Posttransplant Complex Inferior Venacava Balloon Dilatation After Hepatic Vein Stenting

    International Nuclear Information System (INIS)

    Orthotopic and living related liver transplantation is an established mode of treatment of end-stage liver disease. One of the major causes of postoperative complications is vascular anastomotic stenosis. One such set of such complications relates to hepatic vein, inferior vena cava (IVC), or portal vein stenosis, with a reported incidence of 1-3%. The incidence of vascular complications is reported to be higher in living donor versus cadaveric liver transplants. We encountered a patient with hepatic venous outflow tract obstruction, where the hepatic vein had been previously stented, but the patient continued to have symptoms due to additional IVC obstruction. The patient required double-balloon dilatation of the IVC simultaneously from the internal jugular vein and IVC.

  14. Dorsal Hand Vein Biometry by Independent Component Analysis

    Full Text Available Biometric authentication provides a high security and reliable approach to be used in security access system. Personal identification based on hand vein patterns is a newly developed recent year. The pattern of blood veins in the hand is unique to every individual, even among identical twins, and it do notchange over time. These properties of uniqueness, stability and strong immunity to forgery of the vein patterns make it a potentially good biometric trait which offers greater security and reliable features for personal identification. In this study, we have used the BOSPHORUS hand vein database which has been taken under a source of NIR infrared radiation. For feature extraction we applied appearance based method ICA which produces independent components. To control over the number of independent component we preprocessed data by PCA before applying ICA, and gives good experimental results.

  19. Phase equilibrium in systems with ionic liquids: An example for the downstream process of the Biphasic Acid Scavenging utilizing Ionic Liquids (BASIL) process. Part I: Experimental data

    International Nuclear Information System (INIS)

    Highlights: ? Phase equilibrium for a downstream process in sustainable chemical technology. ? Biphasic Acid Scavenging Utilizing Ionic Liquids (BASIL) Process. ? SLE, LLE, and SLLE of (NaCl + water + 1-propanol + 1-MIM) and its ternary subsystems. ? Experimental phase equilibrium data at temperatures between 298 K and 333 K. - Abstract: Experimental results are presented for the (liquid + liquid), (solid + liquid) and (solid + liquid + liquid) equilibria occurring in the downstream process of a typical example for the Biphasic Acid Scavenging Utilizing Ionic Liquids (BASIL)-processes. In a BASIL process an organic base is used to catalyze a chemical reaction and, at the same time, to scavenge an acid that is an undesired side product of that reaction. The particular example of a BASIL process treated here is the reaction of 1-butanol and acetylchloride to butylacetate and hydrochloric acid, where the acid is scavenged by the organic base 1-methyl imidazole (1-MIM) resulting in the ionic liquid 1-methyl imidazolium chloride. The reaction results in a two-phase system as butylacetate and the ionic liquid reveal a large liquid–liquid miscibility gap. The organic base has to be recovered. This is commonly achieved by treating the ionic liquid–rich liquid phase with an aqueous solution of sodium hydroxide (i.e., converting the ionic liquid to the organic base) and extracting the organic base by an appropriate organic solvent (e.g., 1-propanol). The work presented here deals in experimental work with the (liquid + liquid), (solid + liquid) and (solid + liquid + liquid) phase equilibria that are encountered in such extraction processes. Experimental results are reported for temperatures between about 298 K and 333 K: for the solubility of NaCl in several solvents (1-propanol, 1-MIM), (water + 1-MIM), (1-propanol + 1-MIM), (water + 1-propanol), and (water + 1-propanol + 1-MIM) and for the (liquid + liquid) equilibrium as well as for the (solid + liquid + liquid) equilibrium of the ternary system (NaCl + water + 1-propanol) and of the quaternary system (NaCl + water + 1-propanol + 1-MIM).

  12. Acupuncture Points of the Horse’s Distal Thoracic Limb: A Neuroanatomic Approach to the Transposition of Traditional Points

    Directory of Open Access Journals (Sweden)

    Lisa S. Lancaster

    2012-09-01

    Full Text Available Veterinary acupuncture charts were developed based on the concept of transpositional points whereby human acupuncture maps were adapted to animal anatomy. Transpositional acupuncture points have traditionally been placed in specific locations around the horse’s coronet and distal limb believed to be the closest approximation to the human distal limb points. Because the horse has a single digit and lacks several structures analogous to the human hand and foot, precisely transposing all of the human digital points is not anatomically possible. To date there is no published research on the effect of acupuncture treatment of the equine distal limb points. This paper presents a modified approach to equine distal limb point selection based on what is known from research on other species about the neuroanatomic method of acupuncture. A rationale is presented for modification of traditional equine ting points as well as additional points around the hoof and distal limb that do not appear in the standard textbooks of equine acupuncture. The anatomy and physiology of the equine foot likely to be affected by acupuncture are briefly reviewed. Modified neuroanatomic points are proposed that may be more accurate as transpositional points. As an example of clinical application, a neuroanatomic approach to acupuncture treatment of equine laminitis is presented.

    The importance of morphologic and dynamic lesions of the gastrocnemius vein is underestimated. Color-coded Duplex scanning was performed in 483 patients with varicosities and 869 legs with some venous abnormalities were discovered. Two types of lesion on gastrocnemius veins were founded: incompetence and dilatation usually located on the medial gastrocnemius vein. In 29.34% of the limbs, a medial gastrocnemius vein incompetence was present and a dilatation in 15.42%. Medial gastrocnemius vein incompetence was associated with a mid calf gastrocnemius communicating vein incompetence in 25%. Physiopathological hypothesis could be drawn of our observations. Gastrocnemius veins when incompetent should be ligated flush to the popliteal vein. The high prevalence of gastrocnemius vein should be considered in the management of varicose veins and color-coded Duplex scanning routinely performed before surgery. PMID:8353776

    Pulmonary embolism is a serious, life-threatening condition and most commonly derives from deep vein thrombosis of the lower extremities. Once deep vein thrombosis (DVT) reaches a proximal vein (i.e., popliteal vein or higher), pulmonary embolism reportedly occurs in up to 50% of patients. Case Presentation. We report on an inpatient with major depressive disorder in a catatonic state in whom an asymptomatic proximal deep vein thrombosis of 11 × 70?mm was detected through routine screening, u...

    EPVO is a common cause of prehepatic portal hypertension in pediatric patients and sometimes results in cavernous transformation of the PV. We herein present the cases of two patients who underwent LDLT for EPVO with post-Kasai biliary atresia. PV reconstruction was performed with a porto-left gastric vein anastomosis. The patient who underwent PV reconstruction using an interposition vein graft is doing well without surgical complications, whereas PV anastomotic stenosis was detected three months after LDLT in the patient who did not receive an interposition vein graft. The availability of vein grafts is limited in the LDLT setting. In such cases, performing PV reconstruction with varicose veins using interposition vein grafts is a feasible and valuable alternative option for obtaining a sufficient portal blood flow. Our experiences suggest that using interposition vein grafts may be appropriate for preventing the anastomotic stenosis caused by the fragility of varicose veins. PMID:23480790

    Introduction. Inferior alveolar nerve transposition (IANT) is a surgical technique used in implantoprosthetic rehabilitation of the atrophic lower jaw which has not been well embraced because of the high risk of damage to the inferior alveolar nerve (IAN). There are cases in which this method is essential to obtain good morphologic and functional rebalancing of the jaw. In this paper, the authors present their experience with IANT, analyzing the various situations in which IANT is the only surgical preprosthetic option. Methods. Between 2003 and 2011, 35 patients underwent surgical IANT at our center. Thermal and physical sensitivity were evaluated in each patient during follow-up. The follow-up ranged from 14 to 101 months. Results and Conclusion. Based on our experience, absolute indications of IANT are as follows: (1) class IV, V, or VI of Cawood and Howell with extrusion of the antagonist tooth and reduced prosthetic free space; (2) class V or VI of Cawood and Howell with presence of interforaminal teeth; (3) class V or VI of Cawood and Howell if patient desires fast implantoprosthetic rehabilitation with predictable outcomes; (4) class VI of Cawood and Howell when mandibular height increase with inlay grafts is advisable.

    2010-06-01

    Full Text Available This essay discusses the phenomenon of the implementation of technologies designed in the management business, with emphasis on relations with public organizations. It proposes a reflection on the concept of sociological reduction by Guerreiro Ramos, recovering its roots in Husserl and Heidegger and [...] their relationship with the concepts of creative adaptation and the translation of managerial issues. Contextualized in the paradigm of new public management and the list of values and assumptions on which this movement is based, the analysis of the reproduction of practices known in private organizations by public ones seeking their legitimacy has revealed the formality and ceremonial aspect of this contemporary phenomenon. The importance of bringing knowledge from the organizational field that subsidizes management as well as the coherence of these cultural objects in terms of concepts and assumptions of organization are highlighted here. The process of transpositions, contrasting with reproducible traits of Brazilian managerial culture that are historically constructed but consistent with the notion of sociological reduction, requires a critical, conscious and engaged attitude on the part of members of the organization not only regarding the relevance of the imported content but also giving new meaning to the concepts underlying the management technologies.

    Abnormal neurodevelopment has been reported for infants who were born with transposition of the great arteries (TGA) and underwent arterial switch operation (ASO). This study evaluates the cerebral metabolism of TGA infants at birth and before ASO and neurodevelopment 1 year after ASO. Proton magnetic resonance spectroscopy (1H-MRS) was performed on 16 full-term TGA brains before ASO within 3-6 days after birth. The brain metabolite ratios of [NAA/Cr], [Cho/Cr], and [mI/Cr] evaluated measured. Ten infants were evaluated at 1 year using the Bayley Scales of Infants Development II (BSED II). Cerebral metabolism of infants with TGA was altered in parietal white matter (PWM) and occipital gray matter (OGM) at birth before ASO. One year after ASO, [Cho/Cr] in PWM remained altered, but all metabolic ratios in OGM were normal. The results of BSID II at 1 year showed delayed mental and psychomotor development. This delayed neurodevelopmental outcome may reflect consequences of the altered cerebral metabolism in PWM measured by 1H-MRS. It is speculated that the abnormal hemodynamics due to TGA in utero may be responsible for the impaired cerebral metabolism and the subsequent neurodevelopmental deficit. PMID:16897317

  1. Detection of caval obstruction by MR imaging in postoperative transposition of the great arteries

    International Nuclear Information System (INIS)

    Vena caval obstruction may cause significant morbidity after atrial repair of transposition of the great arteries (TGA). The authors compared two noninvasive methods of diagnosing vena caval obstruction with cardiac catherization. Gated MR imaging and Doppler echography were performed in 14 patients with TGA (Mustard procedure performed in six patients, Senning procedure in six, imaging performed 0.5-13.5 years after operation). Complete superior (SVC) or inferior (IVC) vena caval occlusion or partial obstruction (? 5 mm Hg mean gradient from cava to systemic venous artium) was present at catheterization in seven of 14 patients. MR imaging directly displayed complete SVC obstruction in both patients with this catheterization-proved diagnosis. A dilated azygous-hemiazygous complex (? 5 mm in diameter) was seen on MR imaging in five of seven patients with complete or partial vena caval obstruction and in none of seven patients without obstruction. SVC dilation (ratio of SVC to aortic diameter, ? 1.45) was seen in three of five patients with and in none of seven patients without vena caval obstruction. Saline contrast echography, performed in 11 of 14 patients was positive in only two patients with complete SVC obstruction. Turbulent nonphasic flow in the systemic venous atrium was seen on Doppler echography in five of seven patients with and three of seven patients without vena caval obstruction. Thus, MR imaging and Doppler echography are fairly sensitive detectors of vena caval obstruction in postoperative TGA, but MR imaging has greater specificity

  2. Thallium-201 myocardial imaging in case involving transposition of the great arteries after arterial switch operation

    International Nuclear Information System (INIS)

    Forty patients, including 39 with complete transposition of the great arteries and one with double outlet right ventricle, after arterial switch operation were studied with thallium myocardial imaging (TMI). In patients who had post-operative cardiac catheterization, the TMI findings were compared to those of catheterization studies. The right ventricular to left ventricular up-take ratio (RV/LV ratio) shown by TMI correlated well with the right-to-left ventricular systolic pressure ratio. Supravalvular pulmonic stenosis with significant pressure gradient was found in 14 patients, and all of them were noted to have an elevated RV/LV ratio. This ratio was noted to increase progressively on serial TMI studies in most patients who had significant pulmonic stenosis on first post-operative catheterization. Three patients had significant perfusion defects indicating the presence of myocardial damage. Two of them had occlusion of the coronary artery, but the other one had no coronary abnormalities able to be found by coronary arteriography. Air embolism or some other intra-operative transient insults to the myocardium were most likely to have been responsible for the perfusion defects. Thus, TMI was valuable as one of the noninvasive tools for follow-up of patients after arterial switching, particularly for those with late complications such as supravalvular pulmonic stenosis and coronary problems.

  6. Influence of occlusion of hepatic vein on drug concentration in portal vein during drug administration

    International Nuclear Information System (INIS)

    Objective: To evaluate the value of transcatheter chemotherapy through superior mesenteric artery (SMA) and hepatic artery (HA) when hepatic vein (HV) was temporally occluded. Methods: Altogether ten dogs, each of them was undengone four groups of experiments (A, B, C, D) respectively and subjected under self-control. A: transcatheter infusion of 5-Fu by SMA with HV occlusion (SMAI-THVO). B: only transcatheter infusion of 5-Fu throguh SMA(SMAI). C: infusion of 5-Fu through HA with HV occlusion (TAI-THVO). D: only infusion of 5-Fu through HA(TAI). 5 ml PV blood, withdrawn each once at 0.5, 5, 10, 15, 20, 30 min. after infusion of drug for each group respectively, was taken for analysis. The high performance liquid chromatograph (HPLC) was used to measure the blood concentration of 5-Fu in PV for pharmacokinetics, and the post-occlusion angiographic changes were analyzed. Results: The peak concentration (cm) of 5-Fu of occlusion groups (A and C) and the area under the curve (AUC) of 5-Fu were greater than those in control groups (B and D), A>B>C>D(P<0.05). The total value of clearance in occlusion groups (A and C) was lower than that of the control groups (B and C), A< B< C< D(P<0.01). Hepatic arterial angiography showed more arterial branches and dense shadows of the corresponding hepatic segments with hepatic venous occlusion. Conclusion: SMAI-THVO and TAI-THVO can markedly increase the blood concentration of 5-Fu in hepatic tissue and portal vein serving as a dual-route therapy with prolongation of anti-cancer effect.

    The azygos system veins vary greatly in their mode of origin, course, tributaries, anastomoses and termination. Therefore, we aimed to investigate the types of azygos system in this study. Our research was made in Anatomy departments on 48 conserved cadavers aging between 27-70 years, of which 35 were males and 13 females. In the research, the diameters and levels of the azygos vein, the hemiazygos vein, the accessory hemiazygos vein and the superior intercostal vein were investigated. The subjects were classified in Anson's system with a basis of vertical and horizontal connections in the azygos venous system the classification included primitive or embryological types, transient type, unicolon type as three basic types and their eleven subgroups. According to this classification (amongst 48 cadavers), one (2.1%) of our subjects was found to be Type I, 44 (91.7%) of them were found to be Type II, and one (2.1%) was found to be Type III. These values were similar to those in the literature, however two (4.2%) subjects did not fit in any otherwise defined groups and were named as atypic group. It is very important to identify the variations of the azygos system in the computed tomography and magnetic resonance imaging of mediastinum. The abnormal azygos venous system may easily be confused with aneurysm, lymphadenopathy and other abnormalities like tumor. It is important to keep these kinds of variations in mind while performing the mediastinal operations or surgery of large vessels. PMID:23303031

    Full Text Available Abstract Background Tumor thrombus in the portal vein is a common complication of hepatocellular carcinoma, but an extremely rare complication of common bile duct cancer. Case presentation A 78-year-old woman was referred to our department because of jaundice. Laboratory data showed severe liver dysfunction with high serum levels of total bilirubin and CA19-9. Computed tomography showed lesions in the middle bile duct and main portal vein. FDG PET scan and 3D imaging showed hot spots in the same location as those revealed by CT. Under a diagnosis of middle bile duct cancer with portal vein tumor thrombus, the patient underwent surgery. At laparotomy, the main tumor was found to be located in the middle bile duct with a tumor thrombus, 2 cm in diameter, in the main portal vein. The patient underwent pancreatoduodenectomy with thrombectomy. Histological examination showed that this thrombus had the same histological features as those of the main bile duct cancer (poorly differentiated adenocarcinoma. The postoperative course was uneventful and the patient is doing well without any signs of recurrence 18 months after surgery. Conclusion To our knowledge, this is the first report of successful resection of middle bile duct cancer with portal vein tumor thrombus.

    The intraosseous veins of the maxilla in newborns grow larger with enlargement of the bone and become disposed in three mutually perpendicular planes. The venous plexus of the alveolar process is large. V. v. vallares are thin and interlace forming a network. The veins of interdental septum are well pronounced. The thick venous network of the periosteum and the mucous membrane of the nasal surface of the palatine process includes the vessels transversal and longitudinal to the nasal septum. The venous loops of the incisor part are of triangular, pentagonal and polygonal shape. The veins of the palatine process are connected with 3-4 large vessels falling into the vessels of the tear duct. The transversal and oblique veins of the oral surface of the palatine process are connected with large vessels disposed in parallel to the medial structure of the hard palate. The venous network of the incisor part of the bone is restricted by densified small arc-shaped plexuses. Two-three largest veins lie sagittally and, connected by arc-shaped anastomoses, are tributaries of the vessels of the palate bone, soft palate and pharynx. PMID:1217983

  10. Anatomic relationship of intrahepatic bile ducts to portal veins revisited

    International Nuclear Information System (INIS)

    It is well accepted that intrahepatic bile ducts lie in front of corresponding portal vein branches. Since the authors' clinical experience with US was different, they studied 18 normal necropsy cadaver livers. The common bile duct, main portal vein, and hepatic artery were cannulated and injected respectively with air, dilute contrast medium, and mineral oil. The livers were then examined in anatomic position with CT. In the left lobe of the liver, the bile ducts were anterior to the portal vein in seven cases, posterior in seven cases, and were tortuous both anterior and posterior in three cases. In the right lobe, the bile ducts were anterior in nine cases, posterior in five cases, tortuous in one case, and not seen in two cases. In the porta hepatis, the bile ducts were anterior in eight cases, posterior in one case, tortuous in five cases, and not seen in three cases. Histologic specimens confirmed the anterior and posterior location of the bile ducts relative to the portal veins. In conclusion, intrahepatic bile ducts can be either anterior or posterior to the corresponding portal vein branches

    Directional empirical mode decomposition (DEMD) has recently been proposed to make empirical mode decomposition suitable for the processing of texture analysis. Using DEMD, samples are decomposed into a series of images, referred to as two-dimensional intrinsic mode functions (2-D IMFs), from finer to large scale. A DEMD-based 2 linear discriminant analysis (LDA) for palm vein recognition is proposed. The proposed method progresses through three steps: (i) a set of 2-D IMF features of various scale and orientation are extracted using DEMD, (ii) the 2LDA method is then applied to reduce the dimensionality of the feature space in both the row and column directions, and (iii) the nearest neighbor classifier is used for classification. We also propose two strategies for using the set of 2-D IMF features: ensemble DEMD vein representation (EDVR) and multichannel DEMD vein representation (MDVR). In experiments using palm vein databases, the proposed MDVR-based 2LDA method achieved recognition accuracy of 99.73%, thereby demonstrating its feasibility for palm vein recognition.

    Portal vein hypertension generally occurs in liver diseases like hepatic cirrhosis. It causes hemodynamic changes that are closely related to liver disease. At advanced stages of hepatic cirrhosis, portal vein hypertension leads to the atrophy of the right lobe of the liver and the hypertrophy of the left lobe through a process that has not yet been fully explained. Based on the hemodynamic changes that are known to occur, we hypothesize that liver volume is related to the distribution of blood flowing from the splenic vein (SV) that carries hepatotrophic factors from the spleen and pancreas. We studied blood flow in the portal vein system to validate this hypothesis through in vitro experimentation and a computational fluid dynamics (CFD) analysis involving both simplified and patient-specific models based on four healthy subjects and two patients with liver cirrhosis. The results confirmed the hypothesis that right-lobe atrophy is significantly influenced by the distribution of blood from the SV. Moreover, the patients with liver cirrhosis had a significantly larger mass fraction of spleen-derived blood in the left portal vein branch (LPV) than healthy subjects, a result consistent with right-lobe atrophy and left-lobe hypertrophy.

    2005-08-01

    Full Text Available Introduction & Background: Tens of millions of people – up to 40% of women and 25% of men – suffer from lower limb varicose veins. Several risk factors are also identified including genetics, gender, age, obesity, hor-mones, pregnancy, and occupation. Sclerotheraphy is commonly used to treat small varicose veins. Medium-sized and large varicose veins can be removed by a surgical procedure called Stab avulsion or phlebectomy. EVLT is a new alternative surgical method for varicose veins. Patients & Methods: Using 980nm and 940nm diode laser with a 600micron bare-tipped fiber endoluminally under ultrasound and Doppler monitoring, we treated 43 patients in Noor Vein Clinic, Tehran, Iran. Results: The procedure was well tolerated by all patients with just a local anesthesia. No major complications were encountered. We noticed that 980nm and 940nm are the perfect wave lengths causing less post-operational discomfort for patients with enhanced recovery time due to fewer traumas to the adjacent tissues. One small size skin burn and local paresthesia were observed. Conclusion: We concluded that EVLT with diode laser is a safe, fast, and effective method with low recurrence rate.

    2005-01-01

    Full Text Available INTRODUCTION Medial rotation deformity of the hip is a problem to patients who are handicapped by cerebral palsy but able to walk, because the knees point inward during gait („kissing patellae" and cause falls and frequent injuries. Knees and ankles are subject to stress and, therefore, they assume compensating positions. Lower legs assume position of valgus and external rotation, whereas feet rotate either inwards or outwards. Secondary deformities make gait more difficult and cause rapid tear of footwear. AIM The purpose of the paper was to retrospectively analyze the effects of transposition of the gluteus medius and minimus muscles, a procedure introduced for the first time in our country in order to correct the deformity. A new method of binding the muscles by wire was described. There had been no previous experience with this method. METHOD This operation was indicated in patients with spastic form of cerebral palsy, who were able to walk, who had difficulties in gait and whose lateral rotation was less than 10° along with the medial rotation of over 70° of the hip on the side of the deformity. Additional prerequisite for the operation was the absence of flexion contracture of more than 15° of either the hip or the knee on the side of deformity, as there is possibility of aggravation of the flexion hip deformity due to transposed gluteal muscles (now in front of the hip joint. Fifteen hips of 10 patients were operated on. Five patients were operated on bilaterally at one time. The average age was 8 (6-12 years. The majority of patients, 8 (80% were aged between 6 and 8. The average follow-up was 5 years (3-8. The assessment of the results was based on the comparison of rotational abilities of both hips before and after the operation (in unilateral and bilateral deformities, as well as on individual complaints before and after the operation. In patients with unilateral deformity, their „healthy" hips were the control hips. The analysis of the femoral neck anteversion before and after operation was performed. RESULTS Average values of medial and lateral rotation of the deformed hips before operation exhibited significant statistical difference when compared to control hips. The difference of average values of rotatory movements of control and operated hips was not statistically significant after operation. The difference of average preoperative values of the femoral neck anteversion in hips with deformity was statistically significant (49.40±4.63° compared to 32.8±3.1G. Postoperative average values of anteversion in operated and control hips were not statistically significant. The difference between average preoperative (49.40±4.63° and postoperative (35.80±7.66° values of the femoral neck anteversion was statistically significant. Excellent results were achieved in 5 (50% patients, i.e. 8 (53.3% hips; good results were achieved in 3 (30% patients, i.e. 5 (33.3% hips; poor result in 2 (20% patients, i.e. 2 (13.3% hips. All 5 patients who had undergone surgery of both hips had symmetric outcome. Three patients had excellent results, while two had good results. Patients with excellent and good results (80% of patients, 86.6% of hips showed neither weakening of the operated hip abduction nor pelvic instability (positive Trendelenburgh hip test. No complications were recorded postoperatively. CONCLUSION Transposition of gluteal muscles can be recommended in patients under 10 years of age as there is still a chance for their femoral neck to change orientation, to decrease the anteversion and thus to achieve long-lasting effect. Fixation of transposed muscles by wire proved to be effective.

    Full Text Available Injuries to the pancreas by blunt trauma are uncommon. The association of pancreatic injury with acute portal vein thrombosis secondary to blunt trauma abdomen is furthermore rare. The early diagnosis of the pancreas with injury to the portal vein is challenging and difficult. These injuries are associated with high morbidity and mortality, particularly if the diagnosis is delayed. Accurate and early diagnosis is therefore imperative and computed tomography plays a key role in detection. We present a case of child with a rare combination of pancreatic laceration and acute portal vein thrombosis following a blunt trauma to the abdomen. With extensive literature search we found no such cases has been described previously.

  17. Galen's vein aneurysm as cause of heart failure

    International Nuclear Information System (INIS)

    We present the case of a newborn admitted to the intensive care unit with a heart failure of difficult medical management. A large ductus arteriosus was found. It was surgically corrected, but the heart failure persisted and did not improve with medical treatment. Incidentally, a big Galen's vein aneurysm was found. Galen's vein aneurysm is a rare congenital pathology, originated by a fusion defect of the internal cerebral veins. Due to its low resistance, it produces a picture of high-output heart failure. Large defects may contain 50% to 60% of cardiac output. An aneurysm may be suspected in each newborn or infant with clinical picture of heart failure and right cardiac chamber dilation without any evidence of structural cardiac anomaly

    Portal vein thrombosis (PVT) is a relatively common complication in patients with liver cirrhosis, but several other causes might play an important role in PVT pathogenesis. We present a case of alcoholic chronic pancreatitis complicated by acute extensive PVT. The patient was managed conservatively with danaparoid sodium at first, but the thrombosis gradually extended. We then tried radiological intervention using the direct transhepatic and transjugular intrahepatic postsystemic shunt approaches. Although we were able to successfully catheterize the percutaneous transhepatic portal vein (PTP), we could not achieve recanalization of the portal vein. Therefore, PTP catheterization and systemic intravenous infusion of urokinase and heparin was performed to prevent further progression of the thrombosis and cavernous transformation was finally achieved. Computed tomography (CT) and magnetic resonance cholangiopancreatography revealed a pancreatic stone which had possibly induced dilatation of the tail duct and formation of a pancreatic pseudocyst and caused intractable pancreatitis. We performed endoscopic retrograde cholangiopancreatography and placed a stent in the pancreatic duct, which completely cured the pancreatitis. Retrospectively, the previous CT with curved multi-planar reconstruction was reviewed and a fistula was detected between the pancreatic pseudocyst and splenic vein. We concluded that the etiology of the PVT was not only inflammatory extension from pancreatitis but also a fistula between the pancreatic duct and the splenic vein. PMID:26183509

    In right lobe (RL) living donor liver transplantation (LDLT), portal vein (PV) variations are of immense clinical significance. In this study, we describe in detail our PV reconstruction techniques in RL grafts with variant PV anatomy and evaluate the impact of accompanying biliary variations on the recipient outcomes. In a total of 386 RL LDLTs performed between July 2004 and July 2012, the clinical data on 52 (13%) transplants using RL grafts with variant PV anatomy were retrospectively analyzed. Portal vein anatomy was classified as type 2 in 20 patients, type 3 in 24 patients, and type 4 in eight patients. The PV reconstruction techniques utilized included back-wall plasty (n = 21), back-wall plasty with saphenous vein graft interposition (n = 6), saphenous vein graft interposition (n = 5), cryopreserved iliac vein Y-graft interposition (n = 6), and quiltplasty (n = 3). There was no donor mortality. In a median follow-up of 29 months, none of the recipients had vascular complications. Anomalous PV anatomy was associated with a high (54%) incidence of biliary variations; however, these variations did not result in increased biliary complication rate. Overall, the 1- and 3-year patient survival rates of recipients were 91% and 81%, respectively. Vascular and biliary variations in RL grafts render LDLT technically more challenging. By employing appropriate reconstruction techniques, it is possible to successfully use RL grafts with PV variations without endangering recipient and donor safety. PMID:24252057

  20. Derepression of the plant Chromovirus LORE1 induces germline transposition in regenerated plants

    Transposable elements represent a large proportion of the eukaryotic genomes. Long Terminal Repeat (LTR) retrotransposons are very abundant and constitute the predominant family of transposable elements in plants. Recent studies have identified chromoviruses to be a widely distributed lineage of Gypsy elements. These elements contain chromodomains in their integrases, which suggests a preference for insertion into heterochromatin. In turn, this preference might have contributed to the patterning of heterochromatin observed in host genomes. Despite their potential importance for our understanding of plant genome dynamics and evolution, the regulatory mechanisms governing the behavior of chromoviruses and their activities remain largely uncharacterized. Here, we report a detailed analysis of the spatio-temporal activity of a plant chromovirus in the endogenous host. We examined LORE1a, a member of the endogenous chromovirus LORE1 family from the model legume Lotus japonicus. We found that this chromovirus is stochastically de-repressed in plant populations regenerated from de-differentiated cells and that LORE1a transposes in the male germline. Bisulfite sequencing of the 5' LTR and its surrounding region suggests that tissue culture induces a loss of epigenetic silencing of LORE1a. Since LTR promoter activity is pollen specific, as shown by the analysis of transgenic plants containing an LTR::GUS fusion, we conclude that male germline-specific LORE1a transposition in pollen grains is controlled transcriptionally by its own cis-elements. New insertion sites of LORE1a copies were frequently found in genic regions and show no strong insertional preferences. These distinctive novel features of LORE1 indicate that this chromovirus has considerable potential for generating genetic and epigenetic diversity in the host plant population. Our results also define conditions for the use of LORE1a as a genetic tool.

    Objective To evaluate temporal trends in prenatal diagnosis of transposition of the great arteries with intact ventricular septum (TGA/IVS) and its impact on neonatal morbidity and mortality. Methods Newborns with TGA/IVS referred for surgical management to our center over a 20-year period (1992 – 2011) were included. The study time was divided into 5 four-year periods, and the primary outcome was rate of prenatal diagnosis. Secondary outcomes included neonatal pre-operative status and perioperative survival. Results Of the 340 patients, 81 (24%) had a prenatal diagnosis. Prenatal diagnosis increased over the study period from 6% to 41% (p<0.001). Prenatally diagnosed patients underwent a balloon atrial septostomy (BAS) earlier than postnatally diagnosed patients (0 vs. 1 day, p<0.001) and fewer required mechanical ventilation (56% vs. 69%, p=0.03). There were no statistically significant differences in pre-operative acidosis (16% vs. 26%, p=0.1) and need for preoperative ECMO (2% vs. 3%, p=1.0). There was also no significant mortality difference (1 pre-operative and no post-operative deaths among prenatally diagnosed patients, as compared to 4 pre-operative and 6 post-operative deaths among postnatally diagnosed patients). Conclusion The prenatal detection rate of TGA/IVS has improved but still remains below 50%, suggesting the need for strategies to increase detection rates. The mortality rate was not statistically different between pre- and postnatally diagnosed patients; however, there were significant pre-operative differences with regard to earlier BAS and less mechanical ventilation. Ongoing study is required to elucidate whether prenatal diagnosis confers long-term benefit. PMID:25484180

    Full Text Available "nBackground: Nowadays, the treatment of choice for anatomical correction of transposition of great arteries is arterial switch but some children are not good candidates for this operation. In these cases atrial switch or Senning procedure is an accepted method, thus outcome of this procedure needs to be better delineated."n "nMethods: This prospective study included 65 patients that underwent Senning operation in Shahid Rajaee Hospital in Tehran, Iran from 2002 to 2009 and were followed-up for one year."n "nResults: The early and late mortality rates were 16.9% and 1.5%, respectively. 51.8% of early deaths were due to simple Senning procedure, 38.9% due to a Senning with the closure of ventricular septal defect, with or without the repair of pulmonary artery stenosis, 9.3% related to palliative Senning and one late death due to simple Senning. The most common arrhythmia was accelerated junctional rhythm (18.5%. 15% of cases had Senning pathway obstruction and 1.7% had baffle leaks. Regardless of the mortalities, three patients (5.7% had significant tricuspid regurgitation. Right ventricular systolic dysfunction was found in 13.3% of the cases, primarily in Senning with ventricular septal defect closure (37.5%. One case (1.9% had visible cyanosis and three (5.7% had exertional dyspnea but 94.3% of cases remained in functional class I."n "nConclusion: Since the majority of deaths following Senning procedure occur during the first month, especially on the second day post-operatively, assiduity during early post-operative period is crucial. Tricuspid regurgitation or right ventricular systolic dysfunction was not detected in most patients, suggesting optimistic prognosis for these patients.

    This paper aims to update clinicians on "hot topics" in the management of patients with D-loop transposition of the great arteries (D-TGA) in the current surgical era. The arterial switch operation (ASO) has replaced atrial switch procedures for D-TGA, and 90% of patients now reach adulthood. The Adult Congenital and Pediatric Cardiology Council of the American College of Cardiology assembled a team of experts to summarize current knowledge on genetics, pre-natal diagnosis, surgical timing, balloon atrial septostomy, prostaglandin E1 therapy, intraoperative techniques, imaging, coronary obstruction, arrhythmias, sudden death, neoaortic regurgitation and dilation, neurodevelopmental (ND) issues, and lifelong care of D-TGA patients. In simple D-TGA: 1) familial recurrence risk is low; 2) children diagnosed pre-natally have improved cognitive skills compared with those diagnosed post-natally; 3) echocardiography helps to identify risk factors; 4) routine use of BAS and prostaglandin E1 may not be indicated in all cases; 5) early ASO improves outcomes and reduces costs with a low mortality; 6) single or intramural coronary arteries remain risk factors; 7) post-ASO arrhythmias and cardiac dysfunction should raise suspicion of coronary insufficiency; 8) coronary insufficiency and arrhythmias are rare but are associated with sudden death; 9) early- and late-onset ND abnormalities are common; 10) aortic regurgitation and aortic root dilation are well tolerated; and 11) the aging ASO patient may benefit from "exercise-prescription" rather than restriction. Significant strides have been made in understanding risk factors for cardiac, ND, and other important clinical outcomes after ASO. PMID:25082585

    Full Text Available Purpose: A protective effect for estrogens against cardiovascular problems has long been known. The aim of this study was to investigate the vasorelaxant effect of 17?-Ethynylestradiol (17?-EE on human saphenous vein. Methods: The veins were suspended horizontally between two triangular stainless steel hooks for the measurement of isometric tension in individual organ baths containing 10ml Krebs solution, at 37°C and gassed with carbogen under 3gr optimum tension. The effect of different concentrations of 17?-EE (2-40 ?M on vascular tone was investigated in veins precontracted with PGF2?. Relaxation was measured after 40min and expressed as the percent decrease of initial contraction. To determine the involvement of potassium channels, endothelium, nitric oxide synthase, guanylylcyclase and prostaglandins in the vasorelaxant effect of estrogen, the veins were incubated with tetraethyl ammonium, N-nitro-L-arginine methyl ester, methylene blue or indomethacin, respectively for 20min prior to experimentation. Responses to 17?-EE were directly compared to those obtained in the same tissues in the absence of the inhibitors. Results: The mean relaxations induced by 17?-EE with concentrations of 2, 5, 10, 20 and 40?M in tissues precontracted with PGF2? were 19.8 ±5.5%, 26.1±10.8%, 32.2±7.4%, 48.6±10.8%and56±7.6%, respectively. The results of the inhibition of potassium channels, nitric oxide synthase, guanylylcyclase, cyclooxygenase and removing endothelium in relaxation induced by 17?-EE on precontracted veins with PGF2? proved no significant differences. Conclusion: This study showed that 17?-EE has significant vasorelaxant effect on human saphenous vein in a concentration-dependent manner. This effect is probably independent of potassium channels, nitric oxide synthase, guanylylcyclase, prostaglandin synthesis and endothelium functions.

    Methylation patterns of plants are unique as, in addition to the methylation at CG dinucleotides that occurs in mammals, methylation also occurs at non-CG sites. Genes are methylated at CG sites, but transposable elements (TEs) are methylated at both CG and non-CG sites. The role of non-CG methylation in transcriptional silencing of TEs is being extensively studied at this time, but only very rare transpositions have been reported when non-CG methylation machineries have been compromised. To understand the role of non-CG methylation in TE suppression and in plant development, we characterized rice mutants with changes in the chromomethylase gene, OsCMT3a. oscmt3a mutants exhibited a dramatic decrease in CHG methylation, changes in the expression of some genes and TEs, and pleiotropic developmental abnormalities. Genome resequencing identified eight TE families mobilized in oscmt3a during normal propagation. These TEs included tissue culture-activated copia retrotransposons Tos17 and Tos19 (Lullaby), a pericentromeric clustered high-copy-number non-autonomous gypsy retrotransposon Dasheng, two copia retrotransposons Osr4 and Osr13, a hAT-tip100 transposon DaiZ, a MITE transposon mPing, and a LINE element LINE1-6_OS. We confirmed the transposition of these TEs by polymerase chain reaction (PCR) and/or Southern blot analysis, and showed that transposition was dependent on the oscmt3a mutation. These results demonstrated that OsCMT3a-mediated non-CG DNA methylation plays a critical role in development and in the suppression of a wide spectrum of TEs. These in planta mobile TEs are important for studying the interaction between TEs and the host genome, and for rice functional genomics. PMID:26243209

The right circumaortic renal vein crossed the aorta and returned to the inferior vena cava behind the aorta.

  11. Gemstone silica veins in Kremenjacha volcanic rocks (Serbia)

    International Nuclear Information System (INIS)

    The Jeshevac volcanic complex located in central Serbia is made up of various Tertiary volcanic rocks. Kremenjacha hill is situated on the SW rim of the Jeshevac volcanic complex. Silica veins found in this site are made up of chalcedony varieties and crystalline quartz. Jasper veins are examined more thoroughly in this paper. Microscopic analysis has shown it is made up of cryptocrystalline silica with fluidal structure. X-ray powder diffraction analysis of the samples has shown crystalline silica-quartz, ruling out the presence of amorphous silica-opal. The results of spectrochemical analysis have indicated the presence of colouring agents originating mostly from ultramafic and mafic rocks. (Author)

    A 25-year-old woman with dermatomyositis suffered a right central retinal vein occlusion (CRVO) with visual acuity of 20/40. Examination of the right eye showed vitreous cells, suggesting inflammation of the central retinal vein leading to a CRVO as the presumed mechanism. She was admitted to hospital, and extensive evaluation was negative. She was maintained on corticosteroids to manage her dermatomyositis. One month later, she had macular edema and elevated intraocular pressure. Both resolved with dorzolamide, timolol, and intravitreal bevacizumab, and vision returned to 20/20 in the right eye.

    Primary subclavian vein stents are not recommended for venous thoracic outlet syndrome before surgical decompression by first rib resection due to a high risk of fracture because they are compressed between the clavicle and first rib. After rib removal, however, stent insertion has been advocated for venous restenosis, and it is felt that stent fracture is unlikely to occur. We present a case suggesting that repetitive differential vein movement during respiration may be one of the causative factors for stent fractures occurring in this anatomic region. PMID:26122410

    Spermatic phlebography using a transfemoral approach was performed in 24 patients with varicocele disease before occlusion of the gonadal veins by sclerotherapy. The treatment was successful in 23 patients; one patient had to be treated surgically as the spermatic vein was impossible to catheterize selectively. In another group of 20 patients in which surgery was performed without previous phlebography, there were four recurrences of the disease. In a third group of 10 patients surgery was performed after phlebography and in this group the varicocele recurred in one patient.

    We describe a 31-year-old woman with a history of migraines without aura, who presented to our emergency department due to a monocular visual disturbance. This was misdiagnosed as being related to her migraine, however, it was subsequently found to be caused by a central retinal vein occlusion. Patients suffering from migraine can experience visual disturbances in the form of auras. The neuropathological basis for this phenomenon is thought to be a spreading depression in the visual cortex, causing a hemifield active visual phenomenon. Missing the diagnosis of central retinal vein occlusion is common, especially in the setting of an initially normal fundoscopy examination. PMID:26115899

    Objective To pool reliable evidences for the optimum anterior transposition technique in the treatment of cubital tunnel syndrome by comparing the clinical efficacy of subcutaneous and submuscular anterior ulnar nerve transposition. Methods A comprehensive search was conducted in PubMed MEDLINE, Cochrane Library, EMBASE, Web of Science, OVID AMED, EBSCO and potentially relevant surgical archives. Risk of bias of each included studies was evaluated according to Cochrane Handbook for Systematic Reviews of Interventions. The risk ratio (RR) and 95% confidence intervals (CI) were calculated for the clinical improvement in function compared to baseline. Heterogeneity was assessed across studies, and subgroup analysis was also performed based on the study type and follow-up duration. Results Three studies with a total of 352 participants were identified, and the clinically relevant improvement was used as the primary outcomes. Our meta-analysis revealed that no significant difference was observed between two comparison groups in terms of postoperative clinical improvement in those studies (RR 1.04, 95% CI 0.86 to 1.25, P = 0.72). Meanwhile, subgroup analyses by study type and follow-up duration revealed the consistent results with the overall estimate. Additionally, the pre- and postoperative motor nerve conduction velocities were reported in two studies with a total of 326 patients, but we could not perform a meta-analysis because of the lack of concrete numerical value in one study. The quality of evidence for clinical improvement was ‘low’ or ‘moderate’ on the basis of GRADE approach. Conclusions Based on small numbers of studies with relatively poor methodological quality, the limited evidence is insufficient to identify the optimum anterior transposition technique in the treatment of cubital tunnel syndrome. The results of the present study suggest that anterior subcutaneous and submuscular transposition might be equally effective in patients with ulnar neuropathy at the elbow. Therefore, more high-quality randomized controlled trials with standardized clinical improvement metrics are required to further clarify this topic and to provide reproducible pre- and postoperative objective outcomes.

    The Synechocystis sp. PCC6803 insertion sequence ISY100 (ISTcSa) belongs to the Tc1/mariner/IS630 family of transposable elements. ISY100 transposase was purified and shown to promote transposition in vitro. Transposase binds specifically to ISY100 terminal inverted repeat sequences via an N-terminal DNA-binding domain containing two helix–turn–helix motifs. Transposase is the only protein required for excision and integration of ISY100. Transposase made double-strand breaks on a supercoiled ...

  2. A case report of congenitally corrected transposition of great arteries: Morphologic and functional evaluation with cardiac CT

    International Nuclear Information System (INIS)

    Congenitally corrected transposition of the great arteries (ccTGA) is a rare congenital anomaly characterized by atrioventricular and ventriculoarterial discordance. We report a case of new-onset heart failure in a 69-year-old female in whom cardiac CT demonstrated ccTGA without the associated cardiovascular anomalies. In this case, cardiac CT was useful for elucidating the rare and unexpected congenital etiologies of abrupt-onset heart failure in an old patient by the simultaneous evaluation of cardiac morphology and function as a single study (inserted).

    Previous magnetic resonance imaging studies have shown abnormalities of the internal jugular veins in patients with thoracic outlet syndrome (TOS), but this finding has largely been ignored. We, thus, prospectively performed diagnostic brachiocephalic venograms in all patients with diagnosed neurogenic TOS from April 2008 to December 2011 (mean age, 42.6; r, 16-68; 77.8% women and 22.2% men). Stenosis of the left internal jugular vein, left subclavian vein, right internal jugular vein, and right subclavian vein were assessed, and significant stenoses of these vessels were seen in 63.49%, 65.08%, 60.32%, and 68.25% of patients, respectively. Internal jugular vein stenosis was not present in 23.81%, present unilaterally in 28.57%, and present bilaterally in 47.62% of patients. Subclavian vein stenosis was not present in 17.46%, present unilaterally in 28.57%, and present bilaterally in 53.97% of patients. Phi coefficients of correlation were 0.067 between left internal jugular vein and left subclavian vein stenoses, 0.061 between right internal jugular vein and right subclavian vein stenoses, and 0 between any internal jugular vein and any subclavian vein stenoses, indicating there is no correlation between jugular vein stenosis and subclavian vein stenosis in these patients. We conclude that right and left internal jugular vein stenosis is common in patients with neurogenic TOS symptoms. Treatment of internal jugular vein stenosis could potentially benefit these patients, and the implications of these findings warrant further study. PMID:24462538

  7. ATYPIC DRAINAGE PATTERN OF POSTERIOR INTERCOSTAL VEINS INTO THE AZYGOS VENOUS SYSTEM

    Full Text Available The azygos venous system vary greatly in their mode of origin, course,tributaries, anastomoses and termination which resulst predominantly due to its complex embryological development. Azygos venous system develops as right and left azygos venous lines. Right azygos venous line develops into vertical part of azygos vein whereas the left one develops into accessory hemiazygos and inferior hemiazygos veins. These are connected by subcentral/ transvertebral veins. In the present case, we found an atypic drainage pattern of posterior intercostal veins into azygos venous system, left being more variable. Right superior intercostal vein formed by 2nd and 3rd posterior intercostal veins whereas left superior intercostal vein was found to be absent. 2nd, 3rd, 4th & 5th left posterior intercostal veins thus drained into accessory hemiazygos vein. Sixth and seventh left PICVs formed a common trunk with accessory hemiazygous vein and drained into the azygous vein at T6 level. Eighth one united with the hemiazygos vein and formed a common trunk which drained into azygos vein at T8 level. Such variations of the azygos venous system are important for a clinician during mediastinal surgeries to prevent inadvertent hemorrhagic complications.

    Full Text Available Studies have been carried out in order to increase the stability of vegetable oils due to economic and health protection reasons. There is a growing interest in the addition of natural antioxidants; especially herbs and spices. For this reason, this study aimed at evaluating the antioxidant potential of the oleoresins of oregano, basil, and thyme, as well as their behavior when applied to soybean oil under various concentrations. Firstly, the antioxidant activity was determined by the ?-carotene/linoleic acid system and by the quantification of total phenolic compounds. Next, different concentrations of oleoresins (500 to 3000 mg.kg-1 were added to the soybean oil, and its antioxidant potential was analyzed using the oxidative stability through a Rancimat equipment. The value of 3000 mg.kg-1 of thyme and oregano oleoresins was the concentration that presented the greatest oxidative stability to soybean oil making them a natural alternative to vegetable oil conservation.

    A previously healthy, non-smoking, 72-year-old woman was referred to our hospital with abnormal chest X-ray and chest discomfort. A 3.5-cm, well-defined, right paratracheal mass was revealed on non-contrast chest computed tomography (CT), which was suspected to be an azygous vein aneurysm, lymph adenopathy or neurogenic tumor. Whole-body integrated positron emission tomography/magnetic resonance imaging (PET/MRI) (Biograph mMR; Siemens Healthcare, Erlangen, Germany) was performed for the differential diagnosis. A homogenously enhancing mass connected with the azygous vein was well visualized in a post-contrast volumetric interpolated gradient echo (VIBE) sequence. Additionally, the PET showed minimal {sup 18}F-fluorodeoxyglucose (FDG) uptake (maximum standardized uptake value [SUVmax], 1.83), similar to that of the great vessels, with no filling defect to suggest thromboembolism and no significant FDG uptake to suggest active thrombo-embolism or malignancy. The imaging findings in integrated PET/MRI were useful to characterize azygous vein aneurysm. The patient had a video-assisted thoracoscopic surgery to relieve the symptom of chest pain. A congenital etiology of azygous vein aneurysm was confirmed by pathology.

    Full Text Available A distribuição intraparenquimal das veias porta-hepáticas foi estudada em 30 gansos domésticos. Latex Neoprene corado foi injetado pela veia isquiática e os animais forma fixados por imersão e injeção intramuscular com formol a 10% e dissecados. O fígado esteve composto por um grande lobo hepático direito e por um lobo hepático esquerdo menor, os quais estiveram conectados por uma ponte de parênquima. O lobo direito do fígado teve exclusivamente vasos do sistema porta-hepático formados pela distribuição intraparenquimal da veia porta-hepática direita, enquanto que no lobo esquerdo estes originaram-se da veia porta-hepática direita e de pequenas veias porta-hepáticas esquerdas. A veia porta-hepática direita emitiu o ramo caudal direito, que emitiu um pequeno ramo caudolateral direito e um grande ramo caudomedial direito. Cranialmente esta veia emitiu os ramos craniais direito e ramos lateral direito. A porção transversa da veia porta-hepática direita cruzou para o lobo hepático esquerdo, emitindo de 1 a 6 pequenos ramos craniais e caudais para a região média do fígado. No lobo esquerdo, o ramo esquerdo da veia porta-hepática direita emitiu o ramo cranial esquerdo, o ramo lateral esquerdo e o ramo medial. De 1 a 6 veias porta-hepáticas esquerdas foram identificadas desembocando ou no ramo esquerdo da veia porta-hepática direita ou em sua porção transversa, oriundos do ventrículo gástrico e do pró-ventrículo. Em 40% dos gansos uma veia porta-hepática própria oriunda da confluência de vasos venosos da face esquerda do ventrículo distribuiu-se na extremidade caudal do lobo esquerdo isoladamente.The intraparenchymal distribution of the hepatic portal veins in 30 domestic geese were studied. Stained Neoprene latex was injected into the isquiatic vessels, and the animals were fixed in 10% formaldehyde by immersion and intramuscular injection. The liver of geese was composed of a large right and a smaller left hepatic lobe, connected by a parenchyma bridge. The right hepatic lobe had vessels exclusively from the hepatic portal system composed by intraparenchymal distribution of the right hepatic portal vein, while the vessels of the left hepatic lobe came from the right hepatic portal vein and from small left hepatic portal veins. The right hepatic portal vein emitted the right caudal branch, which emitted a small right caudolateral branch and a large right caudomedial branch. Cranially this vein emitted right cranial and right lateral branches. The tranverse portion of the right hepatic portal vein crossed to the left hepatic lobe, emitting 1 to 6 small cranial and caudal branches to the medial area of the liver. In the left hepatic lobe, the left branch from the right hepatic vein emitted the left cranial, left lateral and left median branches. One to six left hepatic portal veins were identified arising from the left branch or from the transverse portion of the right hepatic portal vein. These vessels arose from the gizzard and pro-ventricle. In 40% of geese one proper hepatic portal vein originated from venous vessels of the gizzard and was distributed into the caudal extremity of the left hepatic isolated lobe.

    Full Text Available To study the activity of some antioxidant enzymes and accumulation of compatible osmolytes affected by different concentrations of chromium (Cr+3 (0, 5, 10, 15 and 20 mg/kg soil combined with different levels of manure (0, 10 and 20 ton/ha in basil (O. basilicum L., a factorial experiment, based on completely randomized design with four replications, was carried out at Research Greenhouse of Zabol University in 2012. Results of this study indicated that increasing the level of Cr+3 from 0 to 20 mg/kg soil, when 20 ton/ha manure was applied, decreased the activity of catalase (CAT, ascorbate peroxidase (APX and glutathione peroxidase (GPX enzymes decreased from 0.008, 0.537 and 0.081 to 0.006, 0.305 and 0.071 µmol H2O2/mg protein, respectively. This may be caused by the improvement in physiological activities of the plant in the presence of organic compounds. It seems that application of different amounts of manure led to an increase in leaf proline and carbohydrates content, via availability of macro- and- micro nutrients, especially nitrogen, even when different levels of Cr3+ heavy metal existed in the growth medium. The obtained correlation coefficients indicated a significant positive relationship between most physiological traits, and the highest correlation coefficient (0.84 was found between proline and soluble carbohydrates. It appears that organic compounds, such as manure, have considerable potential to reduce the harmful effects of Cr3+ heavy metal and improve physiological indices of basil.
